Abstract

The present invention provides a heart-lung machine which can be carried by one person and can be used independently from an external power supply, consisting of at least three modules (1, 2, 3), wherein a first module (1) contains the blood circulating elements which are necessary for the function of a heart-lung machine, a second module (2) contains a pump drive (9) and an electronic measuring equipment and a control logic (11) and a third module (3) contains the programming unit (14), whereas the second unit is separably connected to the first and the third module.

Claims

1. A heart-lung machine which can be carried by one person and can be used independently from an external power supply, consisting of three or more modules (1, 2, 3), wherein a first module (1) contains the blood circulating elements which are necessary for the function of a heart-lung machine, a second module (2) contains a pump drive (9) and an electronic measuring equipment and a control logic (11) and a third module (3) contains the programming unit (14), whereas the second unit is separably connected to the first and the third module.

2. The heart-lung machine as claimed in claim 1 consisting of three modules.

3. The heart-lung machine as claimed in claim 1, wherein at least one module is affixed to a housing.

4. The heart-lung machine as claimed in claim 1, wherein said three modules are affixed to a housing.

5. The heart-lung machine as claimed in claim 1, wherein the modules can seperably be connected to each other by means of handholds.

6. The heart-lung machine according to claim 1, wherein modules are affixed to housings which can seperably be connected to each other by means of handholds.

7. The mobile heart-lung machine according to claim 1, wherein the first module comprises a blood-pump (5), an oxygenator (6), a filter (8) and a blood conveying system.

8. The heart-lung-machine according to claim 1, wherein the first module comprises a blood-pump (5), an oxygenator (6), a filter (8), a blood conveying system, a connection for a venous cannula, a reservoir (4) and a connection for an arterial cannula.

9. The heart-lung-machine according to claim 1, wherein the second module comprises a pump drive (9), an electronic measuring equipment and a control logic (11) and valves for adjusting the internal bypass.

10. The heart-kung machine according to claim 1, wherein the second module comprises a pump drive (9), an electronic measuring equipment and a control logic (11), valves for adjusting the internal bypass, an emergency energy supply and operating units for the emergency operation.

11. The heart-lung machine according to claim 1, wherein the second module comprises a pump drive (9), an electronic measuring equipment and a control logic (11), valves for adjusting the internal bypass, an emergency energy supply, operating units for the emergency operation and joints to the first and the third module.
