Description

MULTI-PURPOSE HOSPITAL BED

FIELD OF THE INVENTION

[0001] The present invention relates to a transfer and transport system for immobile prone patients in addition to having the means to facilitate air flow under a patient's back for the prevention of bed sores. Another beneficial object of the invention refers to the means whereby linen on a patient's support surface is conveniently changed with ease and without the necessity of moving the patient. The present invention is related to a changing of hospital gown, bathing, feeding, urinating or defecating a patient without moving the patient.

BACKGROUND OF THE INVENTION

[0002] All medical facilities have part of their routine, the constant transfer of patients from one support surface such as a permanently-placed hospital bed to another support surface such as another bed, a gurney or any other maneuverable support surface. This is inevitable because of the need for patients to be moved to other sections of the medical facility for surgery, further medical tests, x-rays and scans, the soaking of burn victims in water tubs, and etc. The transfer can be very uncomfortable and painful for the patients and may require a number of medical personnel to facilitate the transfer especially with immobile and heavy patients. [0003] Depending on how advanced facilities in a medical establishment are, non-ambulatory patients are moved in various ways. Often, several personnel are required to lift the patient at one time from one bed to another, usually a wheeled contraption, or to a wheelchair before being transported to another section of the medical facility. This leads to work-related complaints from nurses and medical attendants because of back injuries incurred.

[0004] Innovations have been attempted to facilitate the easy transfer and transport of immobile and critically-ill patients. Hoist type lifts wherein patients are suspended in a sling, have been used but this entails positioning the sling under the patient first and then physically lifting the patient which results in the change of the patient's body position and the application of pressure points other than those applied when in a prone position. This can be very uncomfortable for patients, particularly orthopaedic and burn patients. A similar system is the use of roller boards which, again, have to be positioned under a patient before transport and yet may not be able to securely keep the patient in place.

[0005] Other prior transfer devises have not been able to accomplish the transfer of patients in the smoothest pain- free manner possible. There have been conveyors introduced which may serve the purpose but would not be able to accommodate different-sized beds. These devises are set forth in U.S. Pat. Nos. 5, 163, 189; 4,776,047; 4,761 ,841 ; 3,769,642; 3,593,351 ; 3,413,663; 3,302,219; 2,733,452; 2,630,583; 2,536,707; 1,487,171 ; 1,263,611 ; 716,886; and 378,220. Likewise, US patents to DiMatteo and DiMatteo et al entails transferring a prone patient between a bed and another horizontal support by webs which move independently in a lateral direction. But, since the webs are in no way connected, the two support surfaces must be separated from each other during the transfer operation so that the movements of both webs do not interfere with each other. Therefore, the gap between both support surfaces would mean a lapse of support for the patient. In U.S. Pat. No. 4,747, 170 to Knouse, a web is attached to the edge of the sheet on the patient's bed so that as the web is wound onto a roller and it pulls the sheet, and thereby the patient, onto an adjacent support surface. But to do the vice- versa, it must be done from the other side of the bed which may not be accessible to the patient mover.

[0006] Carter, et al in U.S. Pat. No. 5,038,424, has improved on these other systems as described above by inventing a transfer system consisting of two support surfaces with the use of pliable webs, the opposite ends of which are wound about a pair of cylindrical rollers and driven by motors which are hydraulic. Another U.S. Pat. No. 6,591,435 to Hodgetts is similar in the sense that it transports a patient from a bed to a stretcher or vice versa through the use of a bed sheet and a conveyor attached to the bed or the stretcher. A first end of the sheet is removably attached to the conveyor and a second end of the sheet is free. The sheet is adapted to be positioned onto the patient supporting member of the bed or stretcher. The conveyor includes a roller received by bearings. The roller can also include a telescopic arrangement so that its length can be adjusted. [0007] Needless to say, all these contraptions cause discomfort and even pain to the patients being transferred and transported and would not work conveniently for patients in very serious condition. Movements incurred by transferring and transporting patients through such methods may even adversely affect their recovery.

[0008] Although this invention and its embodiments has as its primary purpose the convenient transfer of patients from one support surface to another with the minimum, if not zero, movement of the patient, there are secondary purposes which include the allowance of space and facilitation of air flow under a continuously-prone immobile patient to prevent bed sores; and, the convenient changing of bed sheets under an immobile patient which would ensure a hygienic environment for a critically-ill person forced to stay in hospital for a long period of time.

[0009] Those long-staying patients in medical facilities are often those who are critically ill, critically burned, comatose, or require surgical operations one after the other. Most often they are in a continual prone position subjecting them to the prevalence of pressure sores. Low air loss patient support structures or beds have been known in the medical field for the prevention and treatment of pressure sores. Support Systems International, Inc. has come up with exemplary low air loss beds relating to wound care management and prevention like their Flexicair and Restcue beds. Alternating pressure low air loss beds are also known; for example, U.S. Patent No. 5,044,029 to Vrzalik has air bags positioned alternatively in an inter-digital manner. For this purpose, this present invention would not need any other extra accessory. The planks can be lowered down and away or lowered to the sides and away from the patient's back in an alternating manner to facilitate air flow so that there would still be ample support under the patient whilst permitting air to circulate freely to the skin.

[0010] Again, for long-staying patients to which the slightest movement may cause excruciating pain, there is a need for a system to change bed linen with ease. Routine in hospital is to fold a linen lengthwise and position it along the length of the patient with the folded side pushed a little under the patient's back. Then the patient is turned a little in order to pull the other side of the sheet from underneath. This works only for patients that can be moved without entailing pain. However, this present invention includes 2 or 3 -dimensional planks laid inter-digitally in 2 palettes to give a complete support surface to the patient but each plank, being separate from each other, can thus be fitted with a separate fitted sheet, also 2 or 3 -dimensional. Therefore, they can be rotated periodically so that a clean side is always under the patient until such time that all two or three sides have been soiled and would necessitate its change.

[0011] Although this invention utilizes wooden or aluminium material or any other similar and suitable material to substitute, the planks can also be in the form of air bags which can be inflated or deflated alternatively to fit the purpose of the support surface. In this case, a pneumatic system needs to be introduced and changes made to the apparatus to accommodate such changes. The apparatus can also be changed from being manually operated to being powered, whether by electric, hydraulic, pneumatic, or whatever suitable energy.

[0012] This device to transfer and transport patients will be simple to operate and maintain and would not conflict with the other portions of the medical system; thus accomplishing the transfer and transport of patients from one location to another in a medical establishment in an efficient pain-free manner by a minimum of personnel.

[0013] Also there is a need to have a transport system for patients, which is provided with facility to change a dress and bed sheet of the patient without lifting or moving the patient. Further there is a need to provide a transport system for patients, which is provided with a facility to have a wash of the patients and to enable the patients to feed and to urinate or defecate with ease and convenience.

[0014] The abovementioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.

The system further comprises a means for raising the plurality of predetermined sections wherein the means is manual, pneumatic or mechanical. The system further comprises a means for securing the base center to the rods.

[0087] The plurality of predetermined sections of the bed include a plurality of planks placed in an inter digital position so that the plurality of planks are separated by equal space. Each plank in the plurality of planks is a two dimensional plank. The two dimensional plank is a rectangular plank. Each plank in the plurality of planks is a three dimensional plank. The three dimensional plank is a triangular plank.

[0088] Each of the planks comprises a center base provided with the central axial hole which acts as a rotating center. A soft permanent cover is arranged over the center base and a removable, changeable bed sheet is arranged over the soft permanent cover. Each plank is fitted with a separate bed sheet so that each plank is rotated separately to provide a clean surface always under the patient. Each plank is also removable.

[0089] The system further comprises a handle attached to one end of the axle rod which is attached to the base of the bed to manually rotate one of the pluralities of predetermined sections. The handle is provided with a hole at one end to receive a locking pin to lock the handle with a strong rigid frame in the base of the bed.

[0090] This invention is an apparatus to transfer and transport patients consisting of two similar support surfaces for receiving and supporting a patient before transportation to another location for any purpose deemed necessary by medical staff. They may be manoeuvrable or set on the floor in a permanent manner depending on whether it is to transport a patient or not. Such systems should be accessible in radiology, burn units, testing units and other sections of the medical establishment for the easy, pain-free and convenient manoeuvring of patients.

[0091] The support surfaces of these hospital beds would consist of two palettes and each is made of a series of rectangular 2-dimensional or triangular 3 -dimensional planks inter-digitally positioned. Each palette can be moved interchangeably downwards to the sides, or straight down, and away from a patient's back. The two beds are placed beside each other's free side and when a palette of one bed is lowered down, the corresponding palette of the other, where the patient is to be transferred, is raised up to fill the void created by the lowering down of the previous palette. This is repeated until both the palettes of one bed have taken the place of the palettes of the other bed thereby completing the new support surface where the patient lays. No movement is required from either the patient or any movement caused to the body. The manoeuvrable bed can then be moved away from the other to transport the patient to any location in the medical facility as desired.

[0092] In accordance with the embodiments of the system and as mentioned above, there are two similarly-designed support surfaces or hospital beds to support and receive a prone immobile patient for eventual transport to another section of a medical establishment and these two hospital beds are of two different kinds, one being stable and the other manoeuvrable for the transport of the patient. Both the beds in this invention are operated manually but it is open to the possibility of changing the system from being manual to being pneumatic, hydraulic, electrical, or whatever with the addition of accessories like motors, gears, air and oil jacks, etc. The stable bed rests upon a strong structure made of any durable hard material. The head in each end of the bed has an arch under which the connecting sections are extended from one side of the structure to the other to make the structure more stable. The manoeuvrable bed likewise rests on an equally strong structure made of any durable hard material just like the stable bed but the base of the manoeuvrable bed has wheels attached to the base structure to enable the transport and transfer of patients to another location in the medical establishment.

[0093] An aspect of this invention is that each of the two beds which compose this system has two palettes and each palette is composed of 2- dimensional rectangular or 3 -dimensional triangular planks placed in an inter- digital manner (i.e. there is equal space between each plank). At the sides of the bed heads, there are holes to which each opposite ends of one palette are attached. Corresponding holes also hold firmly in place the other palette. There are holes in both stable and manoeuvrable beds to which are positioned the locking pins which have been set on corresponding holes in each opposite side to serve as locking mechanisms and to keep the palettes in place.

[0094] The embodiments of this invention include the fact that the two palettes in the stable bed are similar to the palettes of the manoeuvrable bed. One is composed of an axle rod which holds it in place to the base of the bed and on each end of the axle rod are two grooves wherein one groove is bored beside the handle end of the axle rod and the another groove is bored at the other end. To ensure the permanent stable position of the axle rod to the base structure of the bed, there are 2 curved pins positioned inside the grooves. The axle rod is firmly set into the grooves. This one palette has approximately seven strong rods and each rod has one end attached to the axle rod attached to the bed structure base while the other end of the rod is free to enable the sliding in of a plank. On each rod end are 3 holes angled equally (120 degrees) to each other to which a metal ball bearing assembly positioned on the hole of a plank is set to ensure the stable positioning of the plank on the rod and to prevent unwanted movements. The handle end is attached to the axle rod for easy and convenient manual rotating work. At the end of this handle, there is a hole to which a locking pin is positioned. Likewise, there is a plastic covering at the end of the handle similar to the plastic cover at the ends of motorcycle handle bars. This has no purpose other than for comfort and beauty.

[0095] In accordance with this embodiment, the locking pin is to contribute to the stabilization of the palette when positioned. It is a metal on the handle which is slid into a hole making one locking mechanism to set and which then goes into another hole in the base structure thereby locking the whole palette securely onto the structure base.

[0096] The other palette is composed of an axle rod which holds it in place at the base of the bed. On each end of the axle rod two grooves are provided wherein one grove is positioned beside the handle end and the other groove is positioned at the another end. To ensure the permanent stable position of the axle rod to the base structure of the bed, there are two curved pins arranged in place inside the grooves. The axle rod is firmly set into the grooves. This palette has approximately six rods and each has its one end attached to the axle rod attached to the bed structure base while the other end is free to enable the sliding in of a plank. On each rod end are 3 holes angled equally (120 degrees) to each other to which a metal ball bearing assembly positioned on the hole of a plank is set to ensure the stable positioning of the plank on the rod and to prevent unwanted movements. On each rod of this particular palette, which is one of the two, what is different from the other is that at the end side attached to the axle rod, there is a curvature which is an essential part of the design to ensure that this particular palette does not touch against the other palette. The handle end of the rod is attached to the axle rod for easy and convenient manual rotating work. At the end of this handle is a hole to which a locking pin is positioned. Likewise, there is a plastic covering at the end of the handle similar to the plastic cover at the ends of motorcycle handle bars. This has no purpose other than for comfort and beauty. The locking pin is to contribute to the stabilization of the palette when positioned. It is a metal on the handle which is slid into a hole making one locking mechanism set which then goes into another hole in the base structure thereby locking the whole palette securely onto the structure base. [0097] The planks which have been mentioned can either be rectangular 2- dimensional planks or triangular 3 -dimensional planks which when placed in an inter-digital manner in a series become one palette. Each plank, this composite unit of the two palettes as mentioned, has a center which goes through the whole length of the plank and would be useful in enabling the plank to rotate. The planks are each slid into a corresponding rod as mentioned above which has been attached permanently to the side of the bed structure. Each plank can be made of any solid durable material, whether wood, aluminium or any other suitable material, and each has a hole which is the rotating center and through which the planks are put together to make one palette. To ensure that each plank does not move loosely or shake or cause the turning of the palette thereby leading to the off balance of the patient, a ball bearing assembly has been put in place wherein a round metal ball is attached to a spring and both are positioned inside a hole which is again positioned over another hole in the plank. A groove is made on the hole to keep a curved metal firmly in place. Another groove keeps the metal ball in place. A hole at the end of each rod mentioned above is for the purpose of putting the metal ball bearing assembly in place. Also, this mechanism will enable the palette to stay firm when in one position and not to move unnecessarily.

[0098] Another aspect of the planks is that each has a soft permanent cover, preferably made of foam but may be made of any other suitable soft sponge-like material, which goes around each plank and also around the plank is a removable, changeable bed sheet to keep the permanent cover clean. Through the rotation of each plank this sheet is likewise rotated and thus ensuring that a clean side is always under the patient's back. If the plank is 2- dimensional there would be two sheet changes and if it is 3 -dimensional there would be three sheet changes after which each fitted sheet is slid out and a clean one is put in place. All the planks would be similar in all the four palettes of the two beds.

[0099] Another aspect of the invention is that although it is mentioned that the planks are made of strong, hard and durable material, an alternative would be that instead of using planks as the composite units of the palettes, plastic sacs can be used and which can then be filled with air like a balloon to be pressurized as desired. Pressure can be regulated as desired and this mechanism would not only be useful for the prevention of bed sores in a patient but would also serve the same purpose as claimed above to transfer and transport patients.

[00100] It must be reiterated that the system as described is manual. However, the device can easily be altered in such a way that it can be operated electrically, hydraulically, pneumatically, and etc.

[00101] To transfer and transport a patient, the manoeuvrable bed is positioned beside the stable bed where the patient lies and then the palettes of the manoeuvrable bed are turned 90 degrees downwards to the side of the bed after which one palette of the stable bed is cranked 90 degrees downwards thereby creating spaces to which the planks of one palette of the manoeuvrable bed can fill. The manoeuvrable bed is then slid into the stable bed and a palette is raised 90 degrees upwards to fill up the empty spaces. Next, a palette of the stable bed is cranked downwards and then the other palette of the manoeuvrable bed is raised to fill the empty spaces. The patient is now completely transferred onto the manoeuvrable bed, ready to be transported. Finally, the manoeuvrable bed is separated from the stable bed.

[00102] Still another aspect of the invention is a further beneficial use in that each plank as mentioned above can be separately fitted with separate linen. This gives convenience when changing bed linen without the necessity of lifting the patient or moving the patient even slightly. Palettes can be interchangeably lowered downwards or to the sides away from the patient's back and have their fitted sheets changed. The planks can be rotated periodically to ensure that a clean side is always under the patient.

[00103] It is of further benefit that this invention makes it possible to accommodate the free passage of air flow under the patient's back to prevent the development of bed sores in continuously-prone and critically-ill patients. The palettes can be interchangeably lowered downwards or to the sides away from the patient's back in timed intervals to ensure that the patient's back is uniformly opened to the free flow of air. This is also very important for critically burned patients.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[00206] In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

TYPE A

[00207] With the Type A beds, the position change of the planks in both the stationary and maneuverable beds is made possible by the manual method. However, it should be noted that movement of the rod can likewise be facilitated by electronic and mechanical control with the use of accessories such as motors and gear boxes. This system has been designed to move the planks in rods in an upwards and downwards motion.

[00208] A detailed description of the embodiments herein commences with reference to Figs. l, 2 & 3, there is a triangular 3-dimensional plank 1 which when placed in an inter-digital position in a series becomes one palette. It must be mentioned here that this plank 1, this composite unit of the palette, do not have to be only 3- dimensional. It can also be a 2-dimensional rectangle. Each plank has a center 2 which goes through the whole length of the plank and would be useful in enabling the plank to rotate. The planks are each slid into a corresponding rod 7 and each of these rods has been attached permanently to the side of the bed 23.

[00209] Each plank can be made of any solid durable material, whether wood, aluminum or any other suitable material, and each plank has a hole 4 which is the rotating center and through which the planks are put together to make one palette. To ensure that each plank does not move loosely or shake or cause the turning of the palette thereby leading to the off balance of the patient, a ball bearing assembly has been put in place wherein a round metal ball 8 is attached to a spring 9 and both are positioned inside a hole 10 which is again positioned over hole 4 in the plank (Figs 6, 1 & 8). A groove is made on hole 10 to keep a curved metal 12 in place firmly. Another groove 13 keeps the metal ball in place. [00210] Hole 14 is provided at the end of each rod 7 for the purpose of putting the metal ball bearing assembly in place (Figs. 4 & 5). Also, this mechanism will enable the palette to stay firm when in one position and not to move unnecessarily.

[00211] Each plank has a soft permanent cover 5, preferably made of foam but may be made of any other suitable soft sponge-like material, which goes around each plank.

[00212] An alternative is given as part of this invention. The Type C beds, details of which are given below, use plastic sacs instead of planks as the composite units of the palettes. These sacs are then filled with air like a balloon to be pressurized or depressurized as desired to alter their volume and thus, their size. (Figs. 51 - 58)

[00213] Also around the plank is a removable changeable bed sheet 6 to keep a clean permanent cover 5 and through the rotation of each plank, this sheet 6 is rotated likewise and thus ensuring that a clean side is always under the patient's back. If the plank is 2-dimensional, then there would be 2 sheet changes and if the plank is 3-dimensiona, then there would be 3 sheet changes after which each fitted sheet is slid out and a clean one put in place.

[00214] All the planks would be similar in all the four palettes of the two beds making up the Type A system.

[00215] These two hospital beds are of 2 kinds: one stable and the other maneuverable for the transport of the patient. Both the beds in this invention are operated manually but it should be noted that accessories like motors, gears, air and oil jacks, etc., can be added to change the system from being manual to being pneumatic, hydraulic, electrical, or whatever.

(1) The stable bed (Fig.9)

[00216] Upon the base of the bed rests a strong structure 15 which is made of any durable hard material. The head in each end of the bed has an arch 97 under which the connecting sections 96 are running from one side of the structure to the other to make the structure more stable. They have holes 21 and 22 to which is positioned locking pin 31 which has been set on holes 30 and 42 provided in each opposite side. Each bed has 2 palette 16 (Fig.12) and 29 (Fig.17). Each bed is composed of 2-dimensional rectangular or 3-dimensional triangular planks placed in an inter-digital manner (i.e. there is equal space between each plank). At the sides of the bed heads are holes 17 to which one end of palette 16 is attached and 18 to which the other end is attached. Holes 19 and 20 hold each end of palette 29. (Figs. 10 & 11)

[00217] Palette 16 is composed of an axle rod 23 which holds palette 16 in place to the base of the bed. On each end of the axle rod are two grooves 24 and 25 wherein groove 25 is positioned beside the handle end and groove 24 at the other end (Fig.14 & 15), To ensure the permanent stable position of axle rod 23 in the base structure of the bed 15, there are 2 curved pins 36 (Fig.16) in place inside grooves 24 and 25. Axle rod 23 is firmly set into grooves 24 and 25. [00218] In palette 16 there are approximately seven rods 7. Each rod 7 for each plank is a strong rod in which one end 26 is attached to axle rod 23 while the other end 27 is free to enable the sliding in of the plank. On each rod end 27, there are three holes angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each plank to ensure the stable positioning of the plank on the rod and to prevent unwanted movements.

[00219] Handle end 28 is a rod attached to axle rod 23 for easy and convenient manual rotating work. At the end of this handle is a hole 30 to which a pin 31 is positioned inside (Fig.13). Likewise, there is a plastic covering 32 at the end of the handle similar to the plastic cover at the ends of motorcycle handle bars. This has no purpose other than for comfort and beauty.

[00220] With regards to the pin 31, its purpose is to contribute to the stabilization of the palette when positioned. It is a metal on the handle which is slid into a hole 30 making one locking mechanism set which then goes into a hole 21 in the base structure thereby locking the whole palette onto the structure base 15.

[00221] Palette 29 is composed of an axle rod 33 which holds palette 16 in place to the base of the bed. On each end of the axle rod are two grooves 34 and 35 wherein groove 35 is positioned beside the handle end and groove 34 is positioned at the other end (Fig.19). To ensure the permanent stable position of axle rod 33 in the base structure of the bed 15, there are two curved pins 36 set in place inside grooves 34 and 35. Axle rod 33 is firmly set into grooves 34, 35. [00222] In palette 29 are approximately six rods 37. Each rod 37 provided to receive each plank is a strong rod in which one end 38 is attached to axle rod 33 while the other end 39 is free to enable the sliding in of the plank. On each rod end 39, there are three holes angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each plank to ensure the stable positioning of the plank on the rod and to prevent unwanted movements.

[00223] There is a curvature 40 on rod 37, at the end side attached to axle rod 33 and the curvature 40 which is an essential part of the design to ensure that palette 16 does not touch against palette 29.

[00224] Handle end 41 is a rod attached to axle rod 33 for easy and convenient manual rotating work. At the end of this handle is a hole 42 to which pin 31 is positioned inside (Fig.18). Likewise, there is a plastic covering 32 at the end of the handle similar to the plastic cover at the ends of motorcycle handle bars. This has no purpose other than for comfort and beauty.

[00225] With regards to pin 31, its purpose is to contribute to the stabilization of the palette when positioned. It is a metal on the handle which is slid into a hole 42 making one locking mechanism to set which then goes into a hole 22 in the base structure thereby locking the whole palette onto the structure base 15.

(2) The maneuverable bed [00226] Upon the base of the bed rests a strong structure 43 (Fig.20) which is made of any durable hard material and has holes to keep the palettes in place. There is a hole 44 to position axle rod 23 in place and hole 45 to hold one end of palette 16. The hole 46 keeps in place the head section of palette 29 and hole 47 is for its side handle. The hole 48 facilitates the entry of pin 33 which is in the handle of palette 16 and hole 49 for pin 31 in the handle of palette 29 (Figs.21 & 22).

[00227] This base has 4 wheels 50 attached to the base structure 43 to enable the transport and transfer of patients to another location in the medical establishment.

[00228] The palettes 16, 29 of both stationary and maneuverable beds are similar.

TYPE B

[00229] With the Type B multi-purpose hospital beds, the change in position of the planks is by vertical movement instead of a rotational movement with rods as in Type A. This upward or downward vertical movement can be made possible with a manual jack, a motor or a gear box. In this case, the system makes use of the pneumatic jack. What follows is a description of the parts:

(1) The Pneumatic Stationary Bed (Fig.39)

[00230] The base (Fig.31) of the pneumatic stationary bed 52 is a structure to which other parts are attached. It has four recessed bed plates which hold the pneumatic jacks in place. On each plate are four holes 53 to fit in the screws attaching the pneumatic jack legs.

[00231] The first of the two palettes (Fig.32) making up the pneumatic stationary bed 56 has a U-shaped frame 57 bearing four recessed bed plates 60 with holes 65 (Fig.33). The pneumatic jack is screwed down to the palette 56 through a hole 65. This palette 56 has seven strong rods 59 whose one ends are attached to the structure 57 while the opposite end 27 is free to enable the sliding in of the plank (Figs. 4 & 5). On each rod end 27, there are three holes 14 angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each plank to ensure the stable positioning of the plank on the rod and to prevent unwanted movements. All in all, the first palette of the pneumatic stationary bed has four pneumatic jacks 67, 68, 69, 70 which are screwed down to the base of the bed through recessed bed plates. Their function is to raise the palettes up and down in a vertical direction. Each jack has two pressurised air inlets' and when the pressurised air enters the inlet above the jack, the jack cylinder goes down but when pressurised air enters the inlet under the jack, its cylinder goes up (Fig.35).

[00232] A mechanical tap 71 with a control lever 72 is provided. It functions to route a determined amount of air pressure from the compressor to hoses 73, 74. Moreover, this manual tap has one inlet hole 75 which connects to the air compressor and two outlet holes 76, 77 as well. The lowering and raising of the control lever 72 allows pressurised air to enter either exit hole 76 or 77 (Fig.37).

[00233] There are connecting hoses to allow the routing of pressurised air from the compressor to the manual tap thereby distributing pressurised air to the four pneumatic jacks. Hose 73 connects to inlet holes under the jacks 67, 68, 69, 70 through a 3 -way connector 78. Therefore, when the control lever 72 of the manual tap is raised, pressurised air enters hose 73 through outlet hole 77 thus raising jacks 67, 68, 69, 70 which in turn allow the first palette 56 with its corresponding planks to go up. As for hose number 74, it connects to the inlet holes above the jacks 67, 68, 69, 70 through a 3-way connector 78. When the control lever 72 of the manual tap is lowered, pressurised air enters hose 74 through hole 76 thereby lowering pneumatic jacks 67, 68, 69, 70 which in turn makes palette 56 together with its corresponding planks to go down.

[00234] The second palette (Fig.34) of the two palettes of the stationary pneumatic bed is a U-shaped structure 95 with six legs 96 attached to it wherein one end of each leg lies firmly on the structure while the other end is attached to corresponding rods 7 of the palette planks. These palette rods 7 are strong rods whose ends, as mentioned, are attached to the legs 96 on the structure while their opposite ends are free to allow the sliding in and out of the planks. On each rod end are three holes angled equally (120 degrees) to each other to which the metal ball bearing assembly is set on the hole of each plank to ensure the stable positioning of the plank on the rod and to prevent unwanted movements. Also, there are four recessed bed plates 79 which hold the pneumatic jacks in place. On each plate are four holes 98 to fit in the screws attaching the pneumatic jack legs.

[00235] All in all, the second palette of the maneuverable bed has four pneumatic jacks 80, 81, 82, 83 which are screwed down to the base of the bed and the palette through recessed bed plates. Their function is to raise the palettes up and down in a vertical direction. Each jack has two pressurised air inlets. When pressurised air enters the inlet above the jack, the jack cylinder goes down but when pressurised air enters the inlet under the jack, its cylinder goes up.

[00236] Likewise, a mechanical tap 84 with a control lever 85 is provided to enable the routing of a determined amount of air pressure from the compressor to hoses 86, 87. Moreover, this manual tap has one inlet hole 88 which connects to the air compressor and two outlet holes 89, 90 as well. The lowering and raising of the control lever 84 allows air pressure to enter either exit hole 89 or hole 90 (Fig.38).

[00237] The connecting hoses provided allow the routing of pressurised air from the compressor to the manual tap thereby distributing pressurised air to the four pneumatic jacks. Hose 87 connects to inlet holes under the jacks 80, 81, 82, 83 through a 3 -way connector 78. Therefore, when the control lever 85 of the manual tap is lowered, pressurised air enters hose 87 through outlet hole 90 thus raising jacks 80, 81, 82, 83 which in turn allow the second palette 53 with its corresponding planks to go up. As for the hose 86, it connects to the inlet holes above the jacks 80, 81, 82, 83 through a 3-way connector 78. When the control lever 85 of the manual tap is raised pressurised air enters hose 86 through hole 89 thereby lowering pneumatic jacks 80, 81, 82, 83 which in turn make the second palette together with its corresponding planks to go down.

(2) The pneumatic maneuverable bed (Fig41)

[00238] The base (Fig40) of the pneumatic maneuverable bed is a strong structure 92 to which other parts are attached. For example, the six plank rods 7 of the first palette are attached so that one end of the rods are positioned firmly onto the structure while their opposite ends are free to allow the sliding in and out of the planks, On each rod end, there are three holes angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each plank to ensure the stable positioning of the plank on the rod and to prevent unwanted movements, Also, there are four recessed bed plates which hold the pneumatic jacks in place, On each plate four holes 94 are provided to fit in the screws attaching the pneumatic jack legs. Moreover, the pneumatic maneuverable bed has four wheels 50 to enable the bed to move freely and thereby allowing the convenient transfer of patients from one section to another in any hospital establishment.

[00239] The second palette (Fig.34) of the pneumatic maneuverable bed is exactly the same as the second palette of the pneumatic stationary bed with similar specifications where the pneumatic jacks, the manual tap, and the connecting hoses are concerned (See above for its detailed explanation).

TYPE C BED

[00240] With the Type C hospital beds, the surface of the beds are divided into sections just like the Type A and Type B beds. However, unlike the latter types where planks make up the surface of the beds and are alternatively taken away from and moved towards a patient's back, Type C uses a system of air sacs which are permanently positioned on the bed structure. By regulating the air content of the sacs of one bed, their volume can be reduced and thereby reducing their size. With the reduction of the size of the air sacs, necessary space is freed to allow the air sacs of the other bed to enter and to fill these empty spaces. The Type C multi-purpose hospital bed is actually made of two beds: the stationary and the maneuverable.

(1) The stationary bed (Fig .61)

[00241] The stationary bed of Type C is composed of the following parts: the air sacs 101, the structure 1 16, the manual lever and the connecting hose 120. What follows is a detailed description. The air sacks (Figs. 51-58) are made of a base Center 106, air tubes 108, Divider 113 and Temporary Cover 109.

A. Base Center (106)

[00242] The base center is made of a hard solid material with a hole 107 in the center which plays a part in the rotating function. The air sacs are attached to the palette axle rod 7 from this hole. To prevent the air sacs from moving loosely or from falling out of the palette rod, a ball bearing assembly has been put in place wherein a spring 9 and a round metal ball 8 are arranged inside a hole 102 and positioned over the base center 3. A groove 103 is provided in the upper part of the hole to keep a curved metal spring 12 in place to prevent the spring from being dislodged from the hole. Likewise, an indentation 104 is provided below the hole to keep the metal ball in place. On the palette axle rod, there are three holes 14 to which the metal ball falls in place to allow the rotation and the removal of the air sacs from the palette rod. This mechanism has been designed in such manner that the air sacs while locked in any three positions can be rotated through 120 degrees.

B. Air tubes (108)

[00243] The air tubes are cylindrical sacks which are elastic and these can be found positioned around the base center. When compressed air enters the tubes through inlet hole 110, their volume increases and when compressed air is emptied from the tubes, their volume decreases and thus the tubes would then rest on the base center.

C. Divider (113)

[00244] A divider (Fig.58) has been provided so that each air tube is attached to one part of it. This divider functions to route compressed air to all the air tubes simultaneously. There are outlet holes 114 on the divider which connects to the hole number 110 of the air tubes. Compressed air enters the divider through inlet holes 115 and is passed from the outlet holes 114 to the air tubes.

D. Temporary Cover (109)

[00245] A textile material covers all around each air sac. This sheet protects the air sac from being contaminated and dirtied. However, it is temporary and can easily be replaced when necessary. On the sheets there are holes 111 through which the axle palette rod 7 is passed and other holes 112 through which are passed the inlet holes of the divider 115.

[00246] As for the base (Fig.59) of the stationary bed, it is a strong structure 116 made of hard durable material with an arch 1 17. There are nine rods 7 attached to the axle rod 1 18and each being a strong rod with one end 26 resting on the axle rod 1 18 while its opposite end 27 is free to enable the sliding in of each air sac. On each rod end 27, there are three holes 14 angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each air sac to ensure the stable positioning of the air sac on the rod and to prevent unwanted movements.

[00247] With regards to the manual lever 72, it serves as the handle of a mechanical tap 71 (Fig.37) which functions to route compressed air to the air tubes inside the air sacs through connecting hose number 120. This sort of control tap has an inlet hole 75 which connects the tap to the air compressor as well as two outlet holes 76, 77. When the lever 72 is raised, the compressed air enters the air sacs through outlet hole 76 and when the lever 72 is lowered, the compressed air exits the air sacs through outlet hole 77.

[00248] Finally there is a connecting hose 120 (Fig.61) which functions in routing the compressed air from the mechanical control tap 71 to the air sacs. There are 3 -way connectors provided so that air is distributed simultaneously and equally to all the air sacs.

(2) The Maneuverable Bed (Fig.60)

[00249] The maneuverable bed of the Type C multi-purpose hospital bed is made of similar air sacs to that of the stationary bed (Please see above for detailed explanation).

[00250] The base 119 of the maneuverable bed is a strong structure made of hard durable material. There are eight rods 7 attached to the axle rod 123 and each rod is a strong rod with one end 26 resting on the axle rod 123 while its opposite end 27 is free to enable the sliding in of each air sac. On each rod end 27, there are three holes (14) angled equally (120 degrees) to each other and to which the metal ball bearing assembly is set on the hole of each air sac to ensure the stable positioning of the air sac on the rod and to prevent unwanted movements. Four wheels (50) have been provided for the easy and convenient handling of the whole structure.

[00251] There is also a mechanical tap 71 (Fig.37) with a pump handle that functions to route compressed air to the air tubes inside the air sacs through connecting hose number 121. This sort of control tap has an inlet hole 75 which connects the tap to the air compressor as well as two outlet holes 76, 77. When the lever 72 is raised, the compressed air enters the air sacs through outlet hole 76 and when the lever 72 is lowered, the compressed air exits the air sacs through outlet hole 77.

[00252] Likewise, a connecting hose 121 functions in routing the compressed air from the mechanical control tap 71 to the air sacs. There are 3- way connectors provided so that air is distributed simultaneously and equally to all the air sacs (Fig.62).

[00253] According to one embodiment herein, a Type 4 bed is provided to enable not only the transfer of the patient but also the changing of bed sheets, changing of gown, feeding the patient, bathing the patient, and urinating or defecating the patient easily and effortlessly without lifting the patient physically or without moving the patient in a bed.

TYPE 4 BED

[00254] According to one embodiment of the present invention, a system provided for transferring a patient from one bed to another bed comprises a first bed having a plurality of predetermined sections wherein the first bed is moveable and comprises a surface for resting the patient. A second bed having a plurality of predetermined sections is provided wherein the second bed is moveable and comprises a surface for resting the patient. A means is provided for combining the surface of the first bed with the surface of the second bed by removing at least one of the plurality of predetermined sections of the surface of the first bed and replacing the at least one of the plurality of predetermined sections of the surface of the first bed with at least one of the plurality of predetermined sections of the surface of the second bed without requiring a movement from the patient and without causing any movement to a body of the patient and without lifting the patient.

[00255] The means is an electronic control unit to control a movement of the first bed and the second bed electronically. The electronic control unit is programmed to work automatically during a transferring operation of a patient from one bed to another bed, during a bathing operation of the patient in a bed, during a feeding operation of the patient in a bed , during urinating process of the patient in a bed and during defecating operation of the patient in a bed wherein the bathing operation, the feeding operation, the urinating process and the defecating operation are preformed without moving a patient out of a bed.

[00256] The pluralities of predetermined sections of the surface of the first bed and the pluralities of predetermined sections of the surface of the second bed have a center base provided with a central axial hole to receive a rod. A vertical hole is connected to the central axial hole. A ball bearing assembly is arranged in the vertical hole. A groove is arranged over the vertical hole and a metal locking pin provided in the groove.

[00257] The first bed and the second bed further comprises an electromechanical system to move the first bed and the second bed to a left direction, to a right direction, in a back ward direction, in a forward direction automatically without any manual intervention. The electro mechanical system comprises a plurality of sensors attached to each of the two frames provided in the first bed and the second bed. The electro mechanical system comprises a first engine coupled to each wheel provided in the first bed and in the second bed to turn the each wheel. The electro mechanical system comprises a spinning wheel. One distal end of the spinning wheel is attached to the wheel and another distal end of the spinning wheel is attached to a first turning mechanism.

[00258] The electro mechanical system comprises a second turning mechanism. The first turning mechanism is rotatably engaged to the second turning mechanism. The electro mechanical system comprises a second engine wherein the second turning mechanism is coupled to a shaft of the second engine. The second engine is operated to move the wheel to a right direction or to a left direction.

[00259] The control unit regulates speed and direction of movement of the wheels. The control unit determines a position of first bed and second bed, based on an output from the sensors.

[00260] Each of the plurality of predetermined sections has a plurality of planks and wherein each of the plurality of planks is lowered or raised independently of each other.

[00261] The electromechanical system comprises a plurality of pneumatic pumps coupled to the plurality of planks respectively so that each of the plurality of planks is operated individually. Each pneumatic pump has an inlet tube for permitting compressed air inside the pneumatic pump and an outlet pipe to exhaust air from the pneumatic pump.

[00262] The pneumatic tap has a control tap connected to the inlet tube and the outlet tube to permit air inside the pneumatic pump through the inlet tube to lift a piston in the pneumatic pump to raise each of the plurality of plank and to exhaust air from the pneumatic pump through the outlet tube to move down the piston from a raised condition to lower each of the plurality of plank.

[00263] The electromechanical system comprises a second electronic control unit to regulate an opening operation and a closing operation of the control tap to regulate a movement of the piston to control a lowering and raising operation of each plank automatically and wherein each of the pluralities of plank is moved vertically up and down alternatively to enable to replace a bed sheet without moving a patient or to enable to change a hospital gown without lifting a patient.

[00264] With respect to FIG 70- 72, an electronic system can make possible electronic communication between the two hospital beds. This system includes an electronic control unit, which has been programmed 146 (FIG.70) to do the necessary tasks without any manual intervention. Each bed has its own electronic control unit 146 and thus making it possible for the system to work automatically when transferring patients, changing sheets or hospital gowns, when bathing patients, feeding them, or when they wish to urinate or defecate. These works are done through electronic coordination between the two beds in this transfer system. On each bed has been provided a mechanical electrical system making it possible for the bed to be moved automatically to the left, to the right, backward or forward without manual intervention. This is also possible because the system has wheels 150, which are turned by an engine 151. Likewise, one spinning wheel 152 is provided, one end of which is attached to the wheel 150 and the other end to the turning mechanism 148. This turning mechanism 148 is attached to the shaft of the engine 149 with the use of a smaller turning mechanism; thus, with the turning of the engine 149, the wheel 150 is moved to the left or to the right, as desired. A control unit 146 regulates speed and the desired direction to which the wheel 150 is to move. Through sensors 153, the control unit 146 initially determines the position of the beds in relation to each other and then simultaneously arranges the planks as programmed; after which the engines 149, 151 move the beds to their positions. Thus patients and tasks pertaining to the patients can be done automatically.

[00265] The mechanism of the planks in Type 4 has been designed in such manner that each plank can be raised or lowered on its own, independent of the rest. This is possible since each plank has its own separate pneumatic pump supplied with the required air pressure through an opening 124 of a tube 125(Fig 71) connected to the control tap. An electronic unit 123 controls the opening and closing of the tap enabling the entry of air pressure through a tube 126 onto a cylinder 121 and exiting through an exit 127 to empty onto the pneumatic pump of a plank through a shaft 122. [00266] This mechanism enables the performance of two tasks. They are as follows. One task is the changing of a bed sheet under a hospital patient without the necessity of moving the patient and the second task is the changing of a patient's hospital gown without a need to lift the patient.

[00267] For performing the first task i.e. the change of a bed sheet under a hospital patient, the steps detailed below are to be followed as shown in FIG 74 -FIG 84. The first plank is lowered (Fig.74). A rolled bed sheet (130) is placed on the first plank which has been lowered (Fig.75). The second plank in the sequence is lowered and the rolled bed sheet is moved onto it (Fig.76). The first plank is raised (Fig.77). The third plank in the sequence lowers down (Fig.78). The bed sheet rolls onto the third plank (Fig.79). The second plank goes up (Fig.80). The fourth plank in the sequence goes down (Fig.81). The bed sheet rolls onto the fourth plank (Fig.82). The third plank goes up (Fig.83). The fifth plank in the sequence goes down (Fig.84). The sequence of steps is repeated until the bed sheet is completely spread out under the patient lying on the bed. To remove the sheet, the same steps are followed but from the opposite end of the bed.

[00268] To change a patient's hospital gown, the following processes are carried out. The mechanism used to change a patient's hospital gown follows the same steps as that of changing a bed sheet except that in this case a hospital gown is rolled and thereafter unrolled under a patient's posterior. Herewith, the hospital gown 130 (FIG.86) has been designed in such manner that after performing the steps mentioned above, the gown completely covers the patient by folding both sides over the body and fastening with buttons, laces, or zippers.

[00269] With respect to FIG. 88 and FIG.89, the gown 130 has buttons 131provided at the front to fasten the gown 130 after putting the gown 130 on the body of the patient. The gown is provided with straps 132 attached to the upper portion of the gown 130 so that the straps 132 are tied after putting on the gown 130.

[00270] In addition to the above, the mechanism makes it convenient to- feed a patient as shown in FIG 90 to FIG 95. The system includes a folding mechanical arm 133 (FIG 87 & FIG 90) attached to rods at one side. This arm 133 has an arc 134(FIG.91) connected to the axle rod 33(FIG 92) through a hole 136 (FIG 93). This folding arm 133 can be rotated and positioned behind a patient thus raising the upper portion of the body to enable the patient to eat meals with ease.

[00271] This system also comes with a mechanical arm 137 (FIG 94) that is equipped with a tube 138 connected to one or more rods. A pin 140 fixed on the axle rod rests on a dent 139 (FIG 95) to prevent the arm from being detached while turning. A spring mechanism 141 ,142 bears the brunt of the force.

[00272] The system also helps the patient to urinate or defecate without moving out of the bed as shown in FIG 96. A tray or bowl or basin 143 is positioned below the bed after moving the folding arm to keep a patient in a raised /slanting position. [00273] When a patient needs to urinate or defecate, one or more planks are removed from under the patient's bottom to create an opening under which a basin 143 is placed for sanitary purposes.

[00274] The process of bathing a patient using the bed is shown in FIG 97 and FIG 98. For bathing a patient, one or more planks are removed from under the patient until enough space is created to drain water properly. A basin 145 (FIG 97, FIG 98) is positioned under the bed to catch the water.
