Abstract

The invention relates to a method and an arrangement for respiratory support for a patient and an airway prosthesis. The spontaneous breathing of a patient is recorded with sensors and an additional amount of oxygen administered by means of a jet gas flow at the end of a lung inhalation process. Oxygen uptake on inhalation is thus improved. Where necessary the exhalation process of the patient can be retarded by a counter-current to prevent a collapse of the airways. The above manner of proceeding is achieved by means of an arrangement, comprising an oxygen pump connected to an oxygen source and an airway prosthesis, which may be connected by means of a catheter. The spontaneous breathing of the patient is recorded by means of sensors, connected to a controller, for activating the oxygen pump. The airway prosthesis has a tubular nozzle body with a connector for the catheter, whereby two of the sensors are provided on the nozzle body. The airway prosthesis and the integrated or introduced jet catheter are of such a size that the patient may breathe and speak freely.

Claims

1. A process for respiratory support for a patient, wherein the patient'"'"'s spontaneous respiration is recorded by sensors, and an additional quantity of oxygen is administered to the lung at the end of an inhalation process.

2. The process according to claim 1, wherein the oxygen quantity has a volume of 25 ml to 150 ml.

3. The process according claim 1, wherein the patient'"'"'s exhalation process is slowed by a counter-flow.

4. An arrangement for respiratory support to a patient, including an oxygen pump to be connected to an oxygen supply, as well as an airway prosthesis, to be connected via a catheter, wherein sensors are intended to record the patient'"'"'s spontaneous respiration, same sensors being connected with a control unit to activate the oxygen pump, and the airway prosthesis possesses a tubular support body with a connector for the catheter, wherein two of the sensors are assigned to the support body.

5. The arrangement according to claim 4, in which a sensor is placed against the interior wall of the support body.

6. The arrangement according to claim 4, wherein the end of the catheter which is located within the support body is redirected so as to be approximately parallel to its longitudinal axis, as well as being provided with a jet nozzle at its end.

7. The arrangement according to claim 4 in which the oxygen pump consists of a piston pump.

9. The arrangement according to claim 4, wherein further respiratory sensors are intended in addition to the sensors.

8. The arrangement according to claim in which the catheter is provided with a double lumen.

10. An airway prosthesis possessing a tubular support body with a connector for a jet catheter, wherein the support body includes at least two sensors.

11. The airway prosthesis according to claim 10, wherein a sensor is affixed to the internal wall of the support body.

12. The airway prosthesis according to claim 10, wherein the catheter end within the support body is directed so as to be parallel to its longitudinal axis.

13. A catheter as a tubular instrument to one of whose ends at least one sensor is affixed.

14. The catheter according to claim 13 in which the end possesses a jet nozzle.

15. The catheter according to claim 13, wherein the end is bent.
