Description

Technical area

The invention relates to a system for mass transfer via diffusion processes with an oxygenation module and an oxygen bottle, which has a carrying device for transporting an oxygenation module and an oxygen bottle, which is designed so that an oxygenation module and an oxygen bottle can be fixed thereon, so that the combination of the carrying device, the oxygenation module and the oxygen cylinder form a system for mobile use.

Background of the invention

Severe trauma, such as burns with inhalation trauma, smoke inhalation, near drowning, or traffic accidents, can cause multiple organ failure. Acute, severe lung failure (ARDS) often occurs. But pneumonia, chronic asthma, cystic fibrosis or pulmonary edema can also lead to serious life-threatening lung failure. However, conventional treatment with highly specialized intensive care ventilators and ventilators is not always sufficient in such cases to ensure an adequate supply of oxygen to the organism.

In the case of the life-threatening clinical picture of ARDS, treatment by means of extracorporeal membrane oxygenation (ECMO) is therefore often indicated. However, ECMO systems are only available at a few specialized treatment centers. Patients with ARDS must be transported to these centers, with an uninterrupted supply of oxygen to the patient during the transport. Mobile artificial lungs were developed for this purpose. Specially designed for the transport of patients with severe lung failure.

In the system of a mobile artificial lung, the patient's blood is passed through an extracorporeal circuit through an oxygenator, for example through a membrane oxygenator, in which the gas exchange required to supply the patient with oxygen takes place. In a membrane oxygenator, which forms a component of the mobile artificial lung, the gas and blood sides are separated from one another by a gas-permeable membrane and the gas exchange takes place through partial pressure differences across the membrane. An oxygenator is for single use only and is discarded after use. A blood pump as a further component of the mobile artificial lung ensures that the blood is conveyed through the oxygenator. The gas, in particular oxygen, is made available from oxygen bottles, which are also a component of the mobile artificial lung.

Various systems are known for transporting the individual components of a mobile artificial lung. The German Offenlegungsschrift DE 43 43 334 A 1 discloses a support structure for a device for mobile external circulatory support. The bridge-shaped support structure with feet protruding downwards in the front and rear area is provided with carrying handles at the front and rear and equipped with fastening means for fixing all components of the device in the operating position.

From the German Offenlegungsschrift DE 197 02 098 A1 a movable carriage with two wheels is known on which the mobile heart-lung machine is attached. Fold-out stands at the corners of the trolley ensure that this trolley is secure. The frame of the trolley is connected to a stretcher using safety brackets, for example, so that it can be transported.

The German Offenlegungsschrift DE 102 20 381 A1 describes a carrying device to which the components of the heart-lung machine are attached and securely fixed. The carrying device is implemented in the form of a carrying frame which has a handle and wheels for transporting the heart-lung machine. With the handle it is possible to tilt the heart-lung machine and move it on the wheels. A firm stand is ensured with this support frame by supporting elements in connection with the wheels.

In the European patent application EP 1 832 303 A 1, the heart-lung machine is transported by hanging a folding bracket, which is bent into a hook on its upper side, on the frame of a patient's bed. The heart-lung machine can be parked on an associated device base after transport.

The German translation DE 60 2005 003 851 T2 of the European patent specification EP 1 796 985 B1 discloses a cardboard basket-like container for carrying bottles such as beverage bottles. The container has a central wall extending in the longitudinal direction, receiving compartments on both sides of the central wall for receiving bottles and a handle section.

The German translation DE 602 02 350 T2 of the European patent specification EP 1 353 729 B1 describes a support device for a cylindrical gas container, for example an oxygen container, which is safely transported in emergency vehicles can and which allows a quick removal of the container for use. The support device includes a mounting bracket for attachment to a rigid support and a rigid frame for securing the container which is releasably connected to the mounting bracket. The carrying device is attached, for example, to an inner surface of an emergency vehicle by means of the mounting bracket.

With the systems shown, a mobile use of artificial lungs is possible, which, however, is mainly limited to a clinical area, since the systems are unwieldy and heavy and in some cases can only be transported in combination with a patient bed or a patient stretcher.

Presentation of the invention

One object of the invention is therefore to create a system for mass transfer via diffusion processes with an oxygenation module and an oxygen bottle that includes a carrying device, the carrying device enabling comfortable transport of an artificial lung outside of a clinical area, for example in an ambulance or helicopter .

This object is achieved by a system for mass transfer via diffusion processes with an oxygenation module and an oxygen bottle, which comprises a carrying device, with the features of independent claim 1. Advantageous further developments of the carrying device emerge from dependent claims 2 to 13.

The invention comprises a system for mass transfer via diffusion processes with an oxygenation module and an oxygen bottle, which comprises a carrying device for transporting an oxygenation module and an oxygen bottle, which is characterized by at least two receiving elements with surfaces facing in opposite directions, on which the oxygenation module or the oxygen bottle can be fixed by means of a fixing agent. The two receiving elements are connected to one another via a connecting element which has a handle that enables simple, safe and ergonomically favorable transport of the oxygenation module or the oxygen bottle and simplifies mobile use.

In one embodiment of the carrying device of the system, the oxygenation module or the oxygen bottle is fixed to the surfaces in an essentially upright position for transport. The expansion of the receiving elements essentially follows the height of the oxygenation module or the oxygen bottle in the upright position. As a result, the oxygenation module or the oxygen bottle rests on the surfaces in some areas and is supported by the carrying device, the hold of the oxygenation module or the oxygen bottle on the carrying device is increased and wearing comfort is improved.

In one embodiment of the carrying device, the receiving elements each have a kink, which creates two sections that are arranged at an angle to one another. The two sections form between them an area in which the oxygenation module or the oxygen bottle, which defines the required size of the angle, can be fixed by means of the fixing means. Due to the resulting zigzag shape, the oxygenation module or the oxygen cylinder with several areas rests against the receiving elements, so that the support of the oxygenation module or the oxygen cylinder is further improved. The oxygenation module or the oxygen bottle is also enclosed in some areas by the receiving elements, so that there is protection against damage during transport.

In another embodiment of the carrying device, the receiving elements each have a curvature, in the concave area of which the oxygenation module or the oxygen bottle can be fixed by means of the fixing means. As a result of the resulting waveform, the oxygenation module or the oxygen bottle is partially enclosed by the receiving elements. This leads to an increase in the safety of the oxygenation module or the oxygen cylinder against damage during transport.

In a further development of the carrying device, the carrying handle is formed by a recess in the connecting element, so that the connecting element can be made in one piece.

In one embodiment of the carrying device, both receiving elements are located on opposite sides of a central plane. The connecting element, which realizes the connection of the two receiving elements, is designed here at an acute angle to the center plane. In this way, the two receiving elements are brought close to the center plane and a device that is comfortable to wear is the result.

In one embodiment, the two receiving elements and the connecting element are formed in one piece. Production of the carrying device is simplified since the necessary assembly steps are omitted.

In a further development of the carrying device, an oxygenation module or an oxygen bottle is fixed with the fixing means on each of the two surfaces. As a result, the weight on the carrying device is evenly distributed and it is easier for one person to carry it with one hand.

The oxygenation module is fixed on one surface and the oxygen bottle on another surface of the carrying device with the fixing means. As a result of the arrangement of these two objects on the carrying device, the result is an artificial lung system which is suitable for mobile use.

One embodiment of the carrying device enables the oxygenation module or the oxygen bottle fixed on one surface with a fixation means to be removable and / or exchangeable individually and independently of an oxygenation module or the oxygen bottle fixed on the other surface with a fixation means. This results in the possibility of reacting variably and quickly to changing requirements during use.

In a further development of the carrying device, it is possible to fix the surface of a receiving element on the body of a person by means of a fixing means. Accordingly, there is no need to transport the carrying device by hand, so that other activities can be carried out.

One embodiment of the carrying device has a display device for displaying data that are output by the oxygenation module or the oxygen bottle. This ensures a direct assignment of the output data to the oxygenation module or the oxygen bottle fixed on the carrying device. Another embodiment of the carrying device has an operating unit for the oxygenation module or the oxygen bottle, so that the fixed oxygenation module or the oxygen bottle no longer needs its own operating unit. One embodiment of the carrying device has both a display device and an operating unit with the advantages resulting therefrom in each case.

One embodiment of the carrying device has a fastening element for a remote control for the oxygenation module or the oxygen bottle, so that the remote control is immediately and directly available.

A further development of the carrying device has a segmentation for collapsing, so that space-saving storage or transport of the carrying device is possible without the objects oxygenation module and oxygen bottle. Furthermore, the segmentation enables the carrying device to be used in a space-saving manner if only one object, oxygenation module or oxygen bottle is to be transported.

The carrying device for the two objects simplifies and facilitates their transport and thus supports a mobile application of the entire system.

The aforementioned and further advantages, special features and expedient developments of the invention also become clear on the basis of the exemplary embodiments which are described below with reference to the figures.

Description of exemplary embodiments

In 1a is schematically a support device 101 shown. The carrying device 101 has two receiving elements 102 with surfaces facing in opposite directions 102a and 102b as well as a connecting element 103 on, in that a handle 104 is integrated for transport. Arrows illustrate the dimensions 105a and 105b the receiving elements 102 . The receiving elements 102 identify the sections of the carrying device 101 , to which objects, namely an oxygenation module or an oxygen bottle, are fixed for transport and the connecting element 103 indicates the section of the carrying device 101 that connects the two receiving elements 102 manufactures.

If necessary, on the receiving elements 102 Fastening aids, such as spacers or the like, can be attached that simplify the assembly of objects and also stabilize the objects on the carrying device 101 support.

The handle 104 is exemplified by a recess in the connecting element 103 and is therefore an integral part of it. Will be the handle 104 directly during the manufacture of the carrying device 101 with trained, additional assembly steps can accordingly be omitted. However, this does not preclude the need to attach to the carrying device 101 an additional element as a handle 104 for transporting the carrying device 101 can be attached.

By means of the fixative 106 it is possible to use different objects, namely an oxygenation module 401 or an oxygen cylinder 402 , to the surface 102a and 102b to fix. As a fixative 106 A variety of options are available for fastening the objects. For variable use of the carrying device 101 For example, tear-resistant flexible materials are suitable, in particular tear-resistant textile tapes which are equipped, for example, with a Velcro fastener as a closure means. In its typical shape, a Velcro fastener is made up of two textile strips, one of which has small barbs and the other of which has loops. The two different strips are pressed together and thus result in a durable quick-release fastener that can be released almost as often as you like. Snap connections, hooks, buckles, etc. offer further possibilities for a closure made of flexible material.

Flexible materials as a fixative 106 can be used universally, as they can be variably adapted to the shape and size of a wide variety of objects. In contrast, when using a rigid bracket as a fixation means 106 the flexibility of the carrying device 101 in relation to a possible use reduced, but the security of the fixed objects against unintentional detachment from the fixation means is increased 106 . Since adaptations to different objects are not possible with a rigid holder, this type of fastening is particularly useful for constant use of the carrying device 101 of interest.

In 1b is schematically a support device 101 with two mounting elements 102 with the curved surfaces 107a and 107b shown. A reciprocal arrangement of the receiving elements 102 with the curved surfaces 107a and 107b on opposite sides of the median plane 108 with simultaneous alignment of the connecting elements 103 at an acute angle to the median plane 108 causes a waveform of the carrying device 101 arises.

In addition to the 1a and 1b illustrated examples of a carrying device 101 with two mounting elements 102 with surfaces facing in opposite directions 102a and 102b and 107a and 107b that have a fastener 103 connects with each other, are also variants of a carrying device 101 conceivable in which this arrangement with further receiving elements 102 , each of which has additional fasteners 103 are connected to each other, is expanded. This makes it possible to transport more than two objects at the same time.

In 2a is schematically a support device 101 with a segmentation 201 shown. This segmentation 201 allows the carrying device to be folded up 101 for example, in the event that only one object is to be transported. This is the carrying device 101 even lighter and easier to use. When storing the folded carrying device 101 Without fixed objects, there is also less space required. A locking device 202 on the carrying device 101 ensures the cohesion of the segments when folded.

The segmentation 201 is realized, for example, by means of a hinge that has a movable connection on one edge of the two receiving elements 102 manufactures. To avoid inadvertent collapsing of the carrying device 101 is segmentation 201 in the open state by means of a locking device 203 locked. Rod or film hinges, for example, but also other hinges or devices for collapsing the carrying device are suitable as hinges 101 , for example joints, are conceivable.

2 B shows an example of a collapsed carrying device 101 in a plan view with the segmentation 201 and associated locking device 202 .

In 3 is schematically an example of a carrying device 101 with an integrated display device 301 , an integrated control unit 302 as well as a remote control 303 shown. The remote control 303 is exemplary by means of a fastening element 304 on the carrying device 101 attached.

On the integrated display device 301 For example, it is possible to display data from one on the carrying device 101 pinned object. In contrast to a display device arranged at a central point, on which data from many different objects and display devices are brought together and displayed at the same time, a direct assignment of the displayed data to the outputting object is thus possible.

Depending on the type of object, the data are, for example, operating or process data or states, characteristic curves or other data of the object that are shown on the display device 301 are representable. In particular, graphic display devices in the form of a screen are recommended as display devices 301 , however, other display devices, for example mechanical or electromechanical display devices, are also suitable for integration in the carrying device 101 imaginable.

Is it the one on the carrying device? 101 fixed object, for example around an oxygenation module 401 , the oxygen saturation and / or the CO ₂ content in the blood, the blood temperature, the flow rate of the blood or the battery status are examples of data that are shown on the display device 301 are representable. With a fixed oxygen cylinder 402 a level indicator would be conceivable, for example.

In addition to displaying the data from one fixed object, there is also the option of displaying the data from two fixed objects, namely from the fixed oxygenation module 401 and from the fixed oxygen cylinder 402 , together on the display device 301 so that a quick overview of the data of both objects is possible. But also the integration of a display device 301 for each fixed object on the respective side of the carrying device 101 is conceivable so that, in turn, an exact assignment of the data to each individual object is possible.

With an integrated control unit 302 is one on the carrying device 101 fixed object controllable. This is particularly important when objects that are predominantly identical or compatible with one another, for example oxygenation modules 401 on the carrying device 101 come into use.

One on the carrying device 101 attached remote control 303 allows control of one on the carrying device 101 fixed object, for example an oxygenation module 401 from a greater distance and independent of direct access to the oxygenation module 401 . The remote control 303 thus enables control without direct visual contact to the object to be steered, for example during transport in a helicopter in which all persons are buckled up and cannot move freely. Through the fastener 304 Is the remote control 303 at a defined location on the carrying device 101 stored and is therefore directly available when required. Examples of a fastener 304 the remote control are: Velcro fasteners, magnetic holders, clip elements or holders for plugging in or on, but also other fastening elements 304 are imaginable.

Alternatively, the fastening element 304 be designed so that both an attachment to the carrying device 101 as well as on a standard standard rail usually attached to operating tables, to which control elements of other devices and facilities can also be connected.

Both an integrated display device 301 as well as an integrated control unit 302 for the oxygenation module 401 lead to a simplified structure of the oxygenation module 401 , to a reduction in the cost of its manufacture and to a possibility of downsizing its structural shape, so that a weight reduction of the oxygenation module 401 and accordingly the artificial lung for mobile transport is reached.

In 4a a system of a mobile artificial lung for use on a patient is shown schematically. The system includes a carrying device 101 in wave form with two receiving elements 102 , in the case of the concave portion of the curved surface 107a by means of a fixative 106 an oxygenation module 401 and in the mutually arranged concave area of the curved surface 107b by means of a fixative 106 an oxygen cylinder 402 is fixed. Both the oxygenation module 401 as well as the oxygen cylinder 402 are partially on the respective curved surface 107a or 107b at. This regional concern of the oxygenation module 401 and oxygen cylinder 402 on the respective curved surface 107a or 107b can, however, also be interrupted accordingly when using fastening aids.

The height 403a of the oxygenation module 401 follows the expansion 105a the curved surface 107a and the height 403b the oxygen cylinder 402 follows the expansion 105b the curved surface 107b . The connecting element 103 with the handle 104 realizes the connection of the two receiving elements 102 with the curved surfaces 107a and 107b , with the handle 104 in this case, for example, both in the connecting element 103 as well as in the two receiving elements 102 is integrated.

To simplify the assembly of the hose systems required for using the system as a mobile artificial lung, they are systematically separated according to their functions on the two opposite sides of the carrying device 101 guided. The tube system for the oxygenation module 401 is thus on the curved surface side 107a and the tube system for the oxygen cylinder 402 accordingly on the curved surface side 107b . On the one hand, this enables easy assignment of the different hose systems to their functions and, on the other hand, offers strain relief for the individual hoses.

A different color design of the curved surfaces 107a and 107b simplifies the assignment of the to the carrying device 101 attached objects to their respective functions. A design option is, for example, red as a label for the side with the oxygenation module 401 and white as identification for the side with the oxygen cylinder 402 at. However, other color combinations are also possible.

Via the integration of other objects, for example filter, detector and sensor systems or also infusion attachments on the carrying device 101 it is possible to expand the mobile artificial lung into a heart-lung machine system for mobile use. Appropriately placed recesses and / or fastening options on the carrying device 101 support and simplify the arrangement, assembly and adjustment of the objects to be attached.

4b shows the system as an example 4a in a top view.

The two independent components oxygenation module 401 and oxygen cylinder 402 the mobile artificial lungs are on the carrying device 101 combined into one system. Due to the mutual distribution of the two components, it is possible to attach the individual weights to the carrying device 101 to distribute so that a unilateral weight load on the carrying device 101 is avoided. Comes as an oxygen bottle 402 If a standardized bottle of e.g. 600ml or 800ml oxygen is used, it is possible to use the known weight of the oxygen bottle 402 by influencing the weight of the oxygenation module 401 balance. This is done, for example, by designing and dimensioning the battery as the energy supply for the oxygenation module 401 , which ensures the network-independent mobile function of the mobile artificial lung or via the selection of the oxygenation module used 401 .

Another way of influencing the weight distribution on the transport device 101 arises when the transport device 101 is designed in a lightweight construction. As in 5a is exemplified by means of this lightweight construction in the connecting element 103 a cavity 501 formed, which is also in one or in both receiving elements 102 can be continued. In this cavity 501 weight elements can then be integrated with which a weight compensation is possible. In addition to the weight elements are in the cavity formed 601 further elements, for example sensors for flow measurements, can also be integrated. One version of the carrying device 101 in a lightweight construction is easy to implement and offers a high level of stability in addition to the possibility of integrating various elements.

5b shows schematically the example of a transport device 101 in lightweight construction in a top view.

The longitudinal alignment of the handle 104 in the connecting element 103 of the system points in the direction of movement of a person and thus supports ergonomically favorable transport by hand by the person. During such a transport, the system is carried as an extension of the natural posture of the person's arm, so that it is not necessary to twist the arm or hand around the handle 104 to be able to enclose. In addition, the arm does not have to be stretched very far away from the body during transport, as the two components of the system adjust the longitudinal direction of the handle during transport 104 following one after the other on the carrying device 101 Are fixed. This high level of comfort makes it easier and, accordingly, if necessary, to transport two systems at the same time by one person.

With a further integration of the handle 104 from the fastener 103 in the two receiving elements 102 the transport of just one component is simplified, for example of the oxygenation module 401 on the system. The resulting one-sided load on the carrying device 101 is compensated for during transport by the fact that the carrying position at which the person holds the handle 104 encloses, in the direction of the oxygenation module 401 shifts. This supports the ergonomically favorable carrying of the carrying device 101 by one person. The ergonomic design of the carrying device 101 Overall, people who are subject to special regulations for carrying objects, such as pregnant women, can also transport a system.

For a transport, the two components become an oxygenation module 401 and oxygen cylinder 402 of the mobile artificial lung in an upright position in the concave areas of the curved surfaces 107a and 107b arranged and fixed so that they are partially removed from the surfaces 107a and 107b be enclosed. This provides additional protection of the components from impact and damage during transport. This is particularly important because of the high gas pressure in the oxygen cylinder 402 which, if not handled properly, can cause the cylinder to explode, especially the oxygen cylinder 402 poses a great risk, which can be reduced by this protection. The requirement for protection of the oxygenation module 401 arises from the need to function properly during treatment of a patient caused by a damaged oxygenation module 401 could no longer be guaranteed.

The roll-off zones of the carrying device provide further protection against damage 101 resulting from the mutual arrangement of the convex areas of the curved surfaces 107a and 107b result and both the carrying device in the event of a collision with another object or an impact 101 as well as those on the carrying device 101 fixed components oxygenation module 401 and oxygen cylinder 402 protect.

From the mutual arrangement of the curved surfaces 107a and 107b this also results in increased stability of the carrying device 101 , so that the use of very light materials is favored and thus a mobile use of the system is supported. The use of various known plastics, such as polyvinyl chloride (PVC) or polycarbonate (PC), is conceivable, although the use of other plastics or materials is not excluded. Materials that can be cleaned quickly and easily are particularly recommended.

The carrying device 101 facilitates positioning and fixation on the body of a person due to the wave shape. This can be both a patient and a person treating the patient or any other person. Only one component of the mobile artificial lung, for example the oxygenation module, is required for this 401 , on the curved surface 107a the carrying device 101 fixed. The fixation on the person's body then takes place on the other curved surface 107b . This type of use is particularly suitable when an oxygen cylinder is present, for example in an ambulance or a helicopter.

The use of the carrying device is supported 101 as part of a system of a mobile artificial lung during a fixation on the body of a patient in that the mobile artificial lung can be used regardless of its position. It is not absolutely necessary to operate the system in a standing position. Treatment can also be carried out if the patient is lying on a stretcher with a fixed mobile artificial lung or is sitting in a wheelchair.

The material for the carrying device is recommended for use on a person's body 101 For example, coated styrofoam, which is low in vibration and light and which, in contrast to other materials such as metal, feels comparatively warmer and softer on the body. A comparable effect is achieved by enveloping Styrofoam or rigid foam with a textile material that can be closed, for example, with a zipper or a Velcro fastener. This simultaneously cleans the transport device 101 facilitated. As additional materials for the carrying device 101 aluminum or carbon also appear suitable.

The fixation of the carrying device 101 on another object, for example a stretcher, a patient's bed or a frame, is also given and is comparable to a fixation on the body of a person. A fixation is also possible here if both the oxygenation module 401 as well as the oxygen cylinder 402 on the carrying device 101 are fixed. Flexible straps with Velcro straps or buckles, which can be variably adapted to different bodies and objects, are suitable for fixation.

Alternatively, one on the carrying device allows 101 attached bracket 404 attaching the carrying device 101 on the one usually found on operating tables Standard standard rail. For attaching the carrying device 101 becomes the holder, which is designed, for example, in the form of a bracket 404 simply hooked into the standard rail of the operating table. An additional one in the fastener 103 integrated handle 405 makes it easier to hang up the carrying device 101 in the standard standard rail.

The oxygenation module 401 and the oxygen cylinder 402 are also separately on a carrying device each 101 fixable. The weight of the mobile artificial lung during transport by hand by a person is thus evenly distributed over both arms of the person and the wearing comfort is thus further increased. The distribution of the components on two carrying devices 101 does not affect a possible fixation on a person's body.

With the integration of one or more additional support elements 406 on the carrying device 101 becomes the stability of the carrying device already given by the wave shape 101 improved. This also provides further protection for the oxygenation module 401 and the oxygen cylinder 402 realized from damage.

Freely available areas of the carrying device 101 that do not contain any objects, operating units, display devices or other elements are available for information, safety information or instructions for use, for example. It also appears expedient to apply pictograms with information about the objects to be attached, via hose guides and / or necessary connections on the associated surfaces of the carrying device 101 . This increases the safety when using the carrying device 101 significantly improved.

This information is applied, for example, directly via an imprint on the carrying device 101 , via stickers or other suitable carrier elements. Different colors, fonts, graphics or other design elements can be incorporated into the design.

For storage before or during an operation, the use of a stand or a frame for receiving the carrying device is designed 101 as appropriate. An example of this are racks such as those used for servers in data centers or for the presentation of television sets.

In 6a is an example of a rack 601 to accommodate the carrying device 101 shown. In the rack 601 the carrying device is located 101 with an oxygenation module 401 and an oxygen cylinder 402 . The rack 601 Is designed so that the carrying device 101 it can also be parked with only one or even without fixed objects. To secure the transport device 101 in the rack 601 are used, for example, locking or clip devices that the transport device 101 Hold in a predetermined position.

By using a rack 601 the already existing stability of the carrying device 101 further increased. The rack also offers 601 an additional protection against damage, for example by impact or impact, if it is with corresponding side walls 602 is provided. Furthermore, the side walls offer 602 protection against dust or splash water and a lining 603 of the rack 601 for example with foam or styrofoam increases the protective effect even more.
