Description

Stretcher for people with mobility disabilities

Technical Field

The present invention relates to a stretcher for patients suffering from complete immobility (quadriplegia) or partial immobility (paraplegia), for patients suffering from alzheimer's disease, for post-operative transfer from an operating room or operating table to a normal stretcher or directly to the bed, or in general, a stretcher can be said to be suitable for persons with mobility difficulties.

Background

Articulated stretchers are known, which can adopt a horizontal configuration in the manner of a bed or an interleaved configuration in the manner of a chair, comprising arms forming three bodies constituting a backrest, a seat and a leg rest, which on the one hand can move in height due to the action of hydraulic cylinders and on the other hand can oscillate with respect to the seat, also by means of hydraulic mechanisms, from a horizontal position to an interleaved position and vice versa.

This type of stretcher allows the disabled to control the operation of the stretcher to take a desired position; however, when the patient has to be transferred from the stretcher to a bed or wheelchair, the assistance of a nurse is required, since this type of stretcher lacks means to facilitate such transfer.

This is even more important if the patient has to be transferred from the operating table to a stretcher or directly to a bed after surgery, since the patient is drowsy from anesthesia and does not cooperate with this action. The nurse transfers the patient using his or her arm, but the nurse may involuntarily cause the suture to burst in one or both patients because there is no homogeneous understanding of the patient's bearing, stretching, or deposition, and because the patient's surgical incision is often not visible, covered by gauze or bandage.

Furthermore, in general, besides combing, cleaning, showering, one of the main concerns of disabled persons is the need for a professional nurse to help them fulfill all the physiological needs of evacuating the physiological waste, even when the patient wishes to move to another place without leaving the bed, for example close to the window for his or her visual entertainment and distraction. In these cases, they also require the help of a nurse.

Summary of The Invention

The present invention relates to a stretcher for persons with mobility impairment, which provides a satisfactory solution to the problems previously set forth, with multiple degrees of freedom, facilitating multiple operations, in particular automatically transferring the patient from the stretcher to a wheelchair or bed, distributing his or her weight, with hardly any action, without requiring the intervention of a nurse, allowing the patient to satisfy his or her physiological evacuation needs directly through the stretcher itself, among others.

A stretcher basically comprises a base or frame, a column that extends or retracts in height relative to the frame, the column having an upper end and a lower end, a fixed central support mounted at the upper end of the column, a front support inclined relative to the fixed central support and a rear support inclined relative to the central support. Likewise, it has front, middle and rear modules that can be coupled to the front, middle and rear supports, respectively, wherein the modules are configured in the inclined area of the patient in his or her recumbent or seated position.

Based on this structure, the stretcher object of the invention is basically prominent in that the module has a transport nest movable in a direction transverse to the support actuated by the drive motor. The socket has a movement in a direction transverse to the support in two directions of movement: towards the exterior of the stretcher for removing the patient from the stretcher, and towards the interior of the stretcher to contain the patient therein.

In order to facilitate the transfer of the patient from the bed to the stretcher, alternative possibilities are envisaged, the stretcher may comprise holding and dragging mechanisms mounted on the support, each having a bucket in contact with the patient, holding him or her in an initial phase and then dragging him or her in the same direction of movement of the nest in a final phase.

In order to cooperate with the action of transferring the patient to or from the stretcher, it is also envisaged that the posts of the support module will also have a tilting movement with respect to the frame and a lateral displacement movement with respect to the frame itself. In this respect, it has been envisaged that the mounting posts are made tiltable relative to a carriage, which in turn is laterally movable relative to a frame, wherein the frame preferably has a central cavity over which the carriage moves.

Furthermore, as previously mentioned, the stretchers can be used to promote physiological evacuation of the patient in the sitting position, in which case the central module comprises two smaller transport stretchers instead of one, the two smaller transport stretchers being arranged distant from each other with a space defined therebetween for allowing evacuation of the patient therethrough, for example a portable toilet, which can be arranged below in correspondence with said space.

It is also envisaged that these pockets will be integrally actuated by a motor and shaft connecting the movement of the two pockets. In this way, the patient can be transferred in a sitting position from the stretcher to a wheelchair arranged close to the stretcher or, conversely, from the wheelchair to the stretcher, activating the movement of the pockets of the central module and of the front and rear modules.

Furthermore, the stretcher also envisages the possibility of moving the front and rear modules with respect to the central module, so as to adapt their position to the dimensions of the patient, wherein each front and rear support comprises for this purpose a respective arm: a stationary arm and an extendable arm opposite the stationary arm, wherein each module is connected to the extendable arm such that it can be actuated at the location of each extendable arm to position the front and rear modules relative to the central module according to the height of each patient.

The stretcher object of the invention may also be rotated by jointly turning the front module, the central module and the rear module with respect to the frame in order to pass from the longitudinal position of the modules into the transverse position, with blocking means fixing said positions. In this way, the patient can change his or her orientation, for example, sitting near a table or looking out of a window.

In addition, it should be noted that the stretcher may be used as a place for personal grooming of the patient, for which it may comprise a bathroom, preferably made of flexible plastic, equipped with a drain, which may preferably be coupled to the module.

Accordingly, it has been envisaged that the frame will include a clean water tank and a dirty water tank from which respective conduits exit, leading to a clean water conduit of the bathing enclosure and a dirty water conduit connected to a drain of the bathing enclosure.

Likewise, the stretcher may include a curtain that may be coupled to the modules, for example, to protect the privacy of the patient while bathing or while meeting his or her physiological evacuation needs.

The stretcher is preferably automated and comprises a set of batteries integrated in the frame, which power the motor and other hydraulic elements, and has connections for connecting auxiliary equipment, such as a dryer, which can be used to dry the patient after bathing.

In short, it is a stretcher that is convenient for physically handicapped persons to voluntarily, since it allows them to move and adopt different positions outside the bed, all the stretcher positions generally having to be adjusted by pressing a command or control element commanding different motors and hydraulic elements, being constrained in these positions in a simple and automatic way.

As such, the stretcher imparts independence to the patient while meeting his or her physiological evacuation needs, without the need for the presence and assistance of others. The last aspect is very important for the patient as it offers the possibility of being able to care for him or herself in the stretcher itself.

Furthermore, it should be noted that the stretcher is of a size suitable for use in hospitals, clinics or outpatient clinics, in particular in private homes, since it has suitable means to pass through doorways 75 cm wide.

Detailed Description

In view of the drawings, the following is a preferred embodiment of a stretcher for mobility impaired people, which constitutes the object of the present invention.

As can be observed in fig. 1, the stretcher essentially comprises a base or frame (1) with a wide central cavity, a carriage (2) movable in a transverse direction within said cavity, a column (3) extending or retracting in height, having an upper end and a lower end, wherein the lower end is assembled to allow tilting with respect to the carriage (2), a central fixed support (4) mounted on the upper end of the column (3), said central fixed support having a front end (6) and a rear end (7).

Likewise, the stretcher comprises a front support (5) inclined with respect to the front end (6) of the fixed central support (4), a rear support (8) inclined with respect to the rear end (7) of the central fixed support (4), a front module (9), a central module (10) and a rear module (11) module respectively couplable to the front support (5), the central support (4) and the rear support (8), with transport sockets (12) destined for moving the patient from the stretcher, for example to a bed or from a bed to a stretcher, actuated by a drive motor.

The modules (9,10,11) can be arranged in a coplanar arrangement in the manner of a bed to facilitate the position of a lying patient who rests his or her lower limbs, torso and head on the front module (9), the central module (10) and the rear module (11), respectively, as shown in fig. 1.

Another possibility envisaged in stretchers is that the modules (9,10,11) will be staggered with respect to the front (9) and rear (11) modules, inclined with respect to the central module (10), in a seating position configured in the manner of a chair or armchair for the patient, as shown in fig. 2, in which the front module (9) serves as a leg support and the rear module (11) serves as a backrest.

As shown in fig. 2, the stretcher may be used to promote the physiological action of the patient through it in this sitting position, for which it is envisaged that the central module (10), which may be coupled to the central support (4), will comprise two smaller transport nests (13) instead of one, the two smaller transport nests (13) being distanced from each other, defining a space between them to allow the physiological evacuation of the patient, as can be observed more clearly in fig. 3.

These smaller sockets (13) are actuated integrally by a drive motor (14) and a shaft (67) connecting the movements of the two smaller sockets (13).

Fig. 4 shows that the anterior support (5) is formed by an inner forearm (15) and an extendable forearm (16), the extendable forearm (16) being longitudinally movable relative to the inner forearm (15). Furthermore, the front module (9) is in turn mounted on extendable forearms (16).

Likewise, the rear support (8) is formed by an inner rear arm (17) and an extendable rear arm (18), the extendable rear arm (18) being longitudinally movable relative to the inner rear arm (17). Furthermore, the rear module (11) is in turn mounted on an extendable rear arm (18).

For the aforementioned reasons, the movement of the extendable forearms (16) determines the overall movement (18) of the front module (9) with respect to the central module (10) in the same way as the movement of the extendable rear arms determines the overall movement of the rear module (11) with respect to the central module (10), which makes it possible to adapt the position of the modules (9,11) to the size of the patient, as can be observed in fig. 4.

Fig. 5 shows how preferably the movement of the extendible arms (16,18) relative to the inner arms (15,17) is performed by means of a rotary switch (23) mounted on the end of the extendible arms (16, 18). These rotary switches (23) rotate the worm (19), the worm (19) being screwed onto a bush (20) firmly connected to the inner arms (15,17) so that they convert the rotary motion of the rotary switch (20) into a longitudinal movement of the extendible arms (16, 18).

In relation to the inclination of the front support (5) or of the rear support (8) with respect to the central support (4) shown in figure 6, and therefore of the front module (9) and of the rear module (11) with respect to the central module (10), a combination of respective motors (21) mounted on the central support (4) has been envisaged, as can be observed in figure 5, or more in detail, in figure 7, with a worm screw (24) which attacks a toothed wheel (22) firmly connected to each front support (5) or rear support (8), so that the rotary action of each motor (21) determines the respective inclination of the front support (5), as can be observed in detail in figure 7, or the respective inclination of the rear support (8) with respect to the central support (4), and is firmly and respectively connected to each front module (9) or rear module (11) with respect to the central module (10), wherein the stretcher adopts the seated position of fig. 2.

As mentioned previously, the height of the column (3) can be extended or retracted, which determines the raising or lowering of the central module (10) and therefore of the front (9) and rear (11) modules, which means that the patient on a stretcher, whether lying or sitting, is raised or lowered depending on the position of the front (9) and rear (11) modules.

Fig. 8 shows that the column (3) is connected at the top to the central support (4) with the head (25) interposed between them and at the bottom to a housing (26) inclined with respect to the aforesaid carriage (2) and that the column (3) comprises a hydraulic cylinder (27) arranged between the housing (26) and the head (25), which causes a vertical movement of the column (3).

The column (3) is formed by various cylinders, including an upper cylinder (29), a middle cylinder (30) and a lower cylinder (31), wherein it is envisaged that the upper cylinder (29) and the central support (4) may be rotated relative to the middle cylinder (30), causing an overall rotation of the modules (9,10,11) from the longitudinal orientation shown in fig. 1 to the transverse orientation shown in fig. 9. In order to fix the stretcher in a longitudinal or transverse orientation, it has been envisaged that the post (3) will comprise an anchoring element (32) connecting the upper cylinder (29) to the intermediate cylinder (30), as can be observed in fig. 8 or illustrated in detail in fig. 9.

In order to fix the position and orientation adopted by the modules (9,10,11), while facilitating the vertical movement of the cylinders (29,30,31), it has been envisaged that the cylinders (29,30,31) will be guided to move between them, for which purpose the upper cylinder (29) and the intermediate cylinder (30) will have guides (68), as shown in fig. 15, for example corresponding to projections (69), as shown in fig. 8, envisaged in the intermediate cylinder (30) and in the lower cylinder (31), respectively, along which said guides (68) move.

Likewise, fig. 8 shows the combination of a hydraulic tilting cylinder (28) arranged between the carriage (2) and the housing (26), which determines the tilting of the housing (26) and thus of the column (3) relative to the carriage (2) during its movement.

The inclination of the column (3) is particularly pointed out to facilitate the transfer of the patient from the stretcher to the bed or vice versa, as shown in fig. 10 or 11.

In these cases, the synchronized action of the modules (9,10,11) is particularly important, more specifically of the cooperating transport nests (12) when the patient is moving to or from the stretcher, as is possible in fig. 10 and 11. In these figures, it is also possible to observe the combination of the fixing and dragging mechanism (71) mounted on the supports (5,4,8) for co-operating with the transport nest (12) in the transfer of the patient from the bed to the stretcher.

Fig. 12 shows that the module (9,10,11) comprises: a drive roller (33) and a driven roller (34) around which the transport nest (12) is continuously moved, a motor (not shown) which drives the transmission (25) causing the drive roller (33) to rotate, a lower tray (36) protecting the nest (12), and a frame (37) with fixing means (38) for fixing the modules (9,10,11) to the supports (5,4, 8).

As can be observed in fig. 13, each of the above-mentioned fixing and dragging mechanisms (71) for moving the patient comprises a mast (39), to which mast (39) can be coupled a container (40) envisaged on each support (5,4,8), see fig. 4, and a cylinder (41) connected to mast (39) having a longitudinally movable extensible rod (42), the end of bucket (43) being associated with extensible rod (42) with a hinge (44) interposed therebetween. The bucket (43) supports the patient during the initial phase of the transfer operation from the bed to the stretcher, as can be observed in fig. 10, and, in the final phase with the opposite orientation, drags the patient, accommodating him or her on the stretcher, as shown in fig. 11.

Fig. 10 also shows that the bucket (43) comprises rollers (70) at the bottom, which can rest on the lower tray (36) in order to hold the patient during the initial transfer movement from the bed to the stretcher, and subsequently keep the rollers (70) in contact with the nest (12) during the dragging movement of the nest (12) as shown in fig. 11.

It has been contemplated that the hinge (44) will include a rotation blocking element that secures the orientation of the bucket (43) in the secured position of fig. 10 or the drag position of fig. 11.

Likewise, the hinge (44) comprises a tilt blocking element that fixes or releases the position of the bucket (43) to facilitate its tilting and lifts the patient during the movement of the extendable rod (42) in order to then switch from the holding orientation to the dragging orientation and vice versa.

The hinge (44) comprises a bolt having a head (45) with a through hole crossed by the end of the extendible rod (42), a cylindrical body (46) emerging from the lower part of the head (45), as shown in fig. 14, comprising, in addition to the above-mentioned rotation blocking means, a bush (47) firmly connected to the back of the bucket (43), said rotation blocking means comprising a thread defined in the cylindrical body (46) and a first nut (48), onto which the first nut (48) is screwed, fixing the orientation of the bucket (43).

The extendable rod (42) of the cylinder (41) is connected to the head (45) by a tilt stop arrangement comprising a thread defined in the extendable rod (42) and a second nut (49) which, once loosened, allows an upward tilting movement of the bucket (43), bushing (47) and bolt around the extendable rod (42) in order to clear the patient during a subsequent extension of the extendable rod (42).

Next, once the bucket (43) has cleared the patient, the bucket (43) is rotated downwards so that its position can be fixed to the extendible bar (42) by means of the second nut (49), in order to then release the first nut (48), which allows the bucket (43) and the bushing (47) to rotate around the cylindrical body (46) until the relative orientation of the shovel (43) corresponding to the dragging position is achieved, to continue the dragging movement of the patient towards the stretcher (see fig. 11).

Furthermore, and with respect to the frame (1), in fig. 15, it can be observed that the central cavity comprises a worm bucket (50) which is attacked by a motor (53) which mounts the carriage (2) and allows the carriage (2) to move laterally with respect to the frame (1). Likewise, the frame (1) has a tubular profile and wheels (51) mounted on extendable members (52) which can be housed in the above-mentioned tubular profile of the frame (1) or can protrude therefrom to promote the sustainability and stability of the stretcher with respect to certain positions and/or orientations of the posts (3) and therefore of the modules (9,10,11) with respect to the frame (1). The frame (1) similarly comprises brakes (54), see also fig. 10, which cooperate in the support and sustainability of the frame (1) in the position in which the wheels (51) extend.

In addition, the possibility of using a stretcher as a personal grooming place for the patient has been envisaged, as can be observed in fig. 16, wherein the stretcher comprises a bathing enclosure (57) equipped with a drainage tube.

The bathing enclosure can be coupled to a module (9,10,11) having fixing means envisaged for this purpose; likewise, the frame (1) comprises a clean water tank (55) from which a clean water pipe (58) emerges towards the stretcher and a dirty water pipe (59) emerging from the dirty water tank (56) and connected to the drain of the bathing hood (57), respectively. Likewise, it is envisaged that a clean water supply conduit (60) and a dirty water drain conduit (61) will emerge from the tanks (55,56), respectively.

Likewise, the stretcher may be considered autonomous due to the combination of batteries (62), the batteries (62) being integrated in the frame (1) and having output connections (63) to couple auxiliary devices of interest, such as a dryer, for drying the patient after bathing and which has a charging socket (64) to facilitate battery recharging (61).

In addition, in this same fig. 16 or 2 it can be observed that the stretcher comprises a curtain (65) that can be coupled to the modules (5,4,8), in particular to the container (40) of the fixed support (4), protecting the privacy of the patient during bathing or while meeting its physiological evacuation needs.
