DETAILED DESCRIPTION

[0063] A holding means 1 shown in FIG. 1 for holding an oxygenator 2 and a blood pump 3 has a frame 4. The frame 4 can be connected with a carrying case housing 13 in a torque-proof way as shown in FIG. 3 and serves for fitting the oxygenator 2 and the blood pump 3 relative to each other. The frame 4 has a frame section 5 and another frame section 6. The oxygenator 2 is connected with the frame section 5 in a torque-proof way and the blood pump 3 is connected with the other frame section 6 in a torque-proof way.

[0064] The holding means 1 also has a handle 7, which is connected with the frame 4 in a torque-proof way. The handle 7 is, in particular, designed as a single piece with the frame 4. The handle 7 is connected with one end of the frame 4 in a torque-proof way here. The frame section 5 and the other frame section 6 are arranged at another end of the frame 4.

[0065] The frame section 5 and the other frame section 6 are arranged in such a way that an oxygenator is arranged closer to the handle 7 than a blood pump outlet 43 shown in FIG. 7, wherein the blood flowing from the blood pump outlet 43 flows into the oxygenator 2 via the oxygenator inlet. The blood pump outlet 43 is therefore arranged further away than the oxygenator inlet 42, viewed from the handle 7 in a vertical direction, so that the direction of the blood flowing out of the blood pump 3 points diagonally upwards. The blood pump 3 is, in particular, arranged in such a way that blood exiting from the blood pump 3 flows in a direction towards the handle 7. The blood flow direction rises in a vertical direction between the blood pump 3 and the oxygenator 2.

[0066] FIG. 2 shows the holding means 1 from a different viewing angle than that of FIG. 1. As is clear from FIG. 2 the handle 7 has a guide 8. The guide 8 serves for guiding fluid lines illustrated in FIG. 7 and has a gap 10, in which the fluid lines shown in FIG. 7 are arranged. In addition, the guide 8 has several protrusions 26, which protrude radially inwards and prevent the fluid lines from falling out of the guide 8.

[0067] The frame 4 of the holding means 1 has another guide 9 for guiding at least one fluid line. The other guide 9 has another gap 11, in which the at least one fluid line is arranged. The other guide 9 has side walls 27, which prevent the fluid line from falling out of the other guide 9.

[0068] FIG. 3 shows a carrying case 12 according to the invention with the holding means 1, which is connected with a carrying case housing 13 in a torque-proof way and is partly arranged in the carrying case housing 13. As is clear from FIG. 3 the handle 7 is arranged outside of the carrying case housing 13. In addition, a part of the frame 4 protrudes from the carrying case housing 13 through a passage opening 25.

[0069] The carrying case housing 13 has a first housing section 14 and a second housing section 15, which are connected with each other in a torque-proof way. The carrying case 12 also has a closing cover 20, which covers part of the second housing section 15.

[0070] A further passage opening 22 is provided on one side of the carrying case 12. A branch line, not illustrated, can extend through the further passage opening 22 and is in fluid-connection with one end of an analysis means not illustrated here. The blood extracted from the patient can be analysed in the analysis means. The other end of the branch line not illustrated here is connected with a connector, via which blood can be branched off.

[0071] The carrying case 12 has a footprint 44, with which the carrying case 12 is placed on a positioning surface, such as for example a floor. The footprint 44 is arranged at an end of the carrying case 12 that lies opposite the handle 7 relative to a horizontal level. When the carrying case 12 is placed on the floor with its footprint 44 the carrying case 12 is aligned in such a way that the oxygenator inlet is arranged in a vertical direction above the blood pump outlet.

[0072] FIG. 4 shows a perspective illustration of the first housing section 14. The first housing section 14 has a first mounting 16. The first mounting 16 serves for receiving a part of the frame 4, the oxygenator 2 and the blood pump 3. The first mounting 16 has a part 28 that serves for receiving the oxygenator 2 for this. In addition, the first mounting 16 has another part 29 that serves for receiving the blood pump 3. In addition, the first mounting 16 has a further part 41 that serves for receiving a part of the frame 4.

[0073] The first housing section 14 delimits the passage opening 25 and the further passage opening 22 together with the second housing section 15. In addition, the first housing section 14 delimits a fluid outlet passage 21 together with the second housing section 15. The fluid outlet passage 21 formed jointly with the second housing section makes it possible that a fluid, such as for example condensate water, can flow out of the carrying case 12.

[0074] FIG. 5 shows a perspective illustration of the second housing section 15. The second housing section 15 has a second mounting 17. The second mounting 17 serves for receiving a part of the frame 4, the oxygenator 2 and the blood pump 3. The second mounting 17 has a part 18 that serves for receiving the oxygenator 2, and another part 19 that serves for receiving the blood pump 3 for this. Part 18 as well as the other part 19 of the second mounting 17 are designed as an opening. In addition, the further part 40 of the second mounting 17 receiving the part of the frame 4 is designed as an opening.

[0075] The second housing section 15 has several elevations 30, which enter corresponding holes provided in the first housing sections 14 for a connection with the first housing section 14. In addition, the second housing section 15 has a recess 31, which is also designed as an opening.

[0076] FIG. 6 shows a carrying case 12 without the closing cover 20. As is clear from FIG. 6 a part of the oxygenator 2, a part of the blood pump 3 and a part of the frame 4 are released due to the design of the second gap 17 described above. This means that the components are visible from the outside. Spare parts and/or sensors and/or the branch line can be arranged in the gap 31.

[0077] The first mounting 16 of the first housing section 14 and the second mounting 17 of the second housing section 15 form a hollow space, in which the oxygenator 2, a part of the frame 4 and the blood pump 3 are arranged in such a way that they cannot move relative to each other and/or not relative to the carrying case housing 13.

[0078] FIG. 7 shows a side section illustration of the carrying case 12 according to a second design with several fluid lines. The section is realised in such a way that the inside of the carrying case housing 13 is visible. As is clear from FIG. 7 the oxygenator 2 and the blood pump 3 are each fluid-connected with several fluid lines.

[0079] The fluid lines include a first line 32, which is fluid-connected with a blood pump inlet 33 at one end. The first line 32 is fluid-connected with the patient at another end. A second line 34 of the fluid lines is fluid-connected with a blood pump outlet 43 at one end. In addition, the second line 34 is fluid-connected with the oxygenator 2, in particular, with the oxygenator inlet, at another end. The blood flowing into the oxygenator 2 flows back to the patient via a third line 36 following the gas exchange.

[0080] In addition, the oxygenator 2 is fluid-connected with a fourth line 37. The oxygenator 2 is supplied with has via the fourth line 37. One end of the fourth line 37 is fluid-connected with a gas source not illustrated in FIG. 3, such as for example a gas tank or a pneumatic control console.

[0081] The blood pump 3 is fluid-connected with three fifth lines 38. The blood pump 3 is supplied with gas, such as for example oxygen or air, by means of the fifth lines 38, or the same is vented from the same. The supply or venting of gas can realise a pump effect, which lastly effects a blood volume flow through the oxygenator 2.

[0082] With the carrying case 12 illustrated in FIG. 7 all fluid lines are guided through the handle 7. All fluid lines extend in the same direction. The three fifth lines 38 are guided through the other guide 9 of the frame 4.

[0083] FIG. 8 shows the use of the carrying case 12 illustrated in FIG. 3 in a hospital room. The carrying case 12 is attached to a hospital bed 39. A patient from whom blood is extracted, which then flows to the carrying case 12, lies in the hospital bed 39. The blood enriched with oxygen in the oxygenator then flows back to the patient.

[0084] The carrying case 12 is also fluid-connected with a device 24 for controlling or regulating a gas volume flow in the fluid lines by means of the fluid lines. The blood volume flow conveyed by the blood pump 3 and the gas volume flow supplied to the oxygenator 2 can be controlled or regulated by controlling or regulating the gas volume flow in the fluid lines. The device 24 is attached to a wall of the hospital room with this application and is fluid-connected with the oxygenator 2 and/or the blood pump 3 via fluid lines. The device 24 is fluid-connected with at least one gas source not illustrated here.

[0085] The design illustrated in FIG. 8 differs from the design illustrated in FIG. 7 in that the fluid lines in fluid connection with the patient extend from the handle 7 in another direction than the other fluid lines connected with the device 24. The fluid lines in fluid connection with the patient can also extend in different directions if patient access is realised at different body points.

[0086] FIG. 9 shows the use of the carrying case 12 illustrated in FIG. 3 in an emergency situation, where a patient lying on the floor is suffering from acute heart or lung insufficiency. The carrying case 12 is placed on the floor. It is clear from FIG. 9, as with FIG. 8, that the carrying case 12 is fluid-connected with the patient via respective fluid lines. In addition, it is clear from FIG. 9 that the carrying case 12 is fluid-connected with the device for controlling or regulating 24. The device for controlling or regulating 24 is fluid-connected with the gas source 23, wherein the device 24 is fluidically arranged between the gas source 23 and the carrying case 12.

[0087] FIG. 10 shows an illustration of a part of the carrying case 12 according to the invention according to a third embodiment example. The carrying case 12 has a fitting device 45, which is fitted on the first housing section 14. The fitting device 45 has a holder 46 and a holder mounting 47. As is clear from FIG. 11 the holder 46 is of a heel-shaped design at both its ends. The two heel-shaped ends are connected with each other by an intermediate bridge 48. The intermediate bridge 48 has a central U-shaped section. The intermediate bridge 48 is visible in FIG. 10, as a plate 49 of the fitting device 45 is illustrated partly transparent. The plate 49 covers a part of the holding mounting 47.

[0088] With the position of the holder 46 illustrated in FIG. 10 this is arranged in the holder mounting 47. The carrying case 12 cannot be connected with the hospital bed in this position of the mounting 46.

[0089] FIG. 11 shows the carrying case 12 according to the third design, wherein the holder 46 is in an unfolded position. The heel-shaped ends of the holder 46 each protrude from the holder mounting 47 and the first housing section 14 and can be connected with the hospital bed that is not illustrated.

[0090] The holder 46 is turned in one direction for transferring the holder 46 from the folded position illustrated in FIG. 10 into the unfolded position shown in FIG. 11. A further turning of the holder in this direction is not possible, as the U-shaped section of the intermediate bridge 48 bumps against the plate 49 and thus prevents a further turning of the holder 46. The U-shaped section is arranged in the gap visible in FIG. 10 in the position of the holder 46 illustrated in FIG. 11.
