Abstract

The present invention relates to a dialyzer, in particular to a peritoneal dialyzer, comprising at least one compressor and comprising at least one pneumatic consumer which is in communication with the compressor such that it can be acted on by compressed air from the compressor, wherein the dialyzer communicates or can communicate with at least one blood pressure cuff such that the blood pressure cuff can be supplied with compressed air by the compressor of the dialyzer.

Claims

1. A dialyzer comprising

at least one compressor,

at least one blood pressure cuff,

a pneumatic system containing at least one pneumatic consumer in communication with the compressor such that the pneumatic consumer can be acted on by compressed air supplied from the compressor, wherein the dialyzer communicates or can communicate with the at least one blood pressure cuff such that the blood pressure cuff can be supplied with compressed air by the compressor, and

at least one valve located between the compressor and the blood pressure cuff and one or more lines between the compressor and the blood pressure cuff can be closed off or released by said valve, wherein the valve is configured as a multiway valve, which is designed such that either the blood pressure cuff or other consumers are in compressed air communication with the compressor.

2. The dialyzer in accordance with claim 1, wherein the dialyzer has at least one connection to which the blood pressure cuff is or can be releasably connected.

3. The dialyzer in accordance with claim 2, wherein the connection is a plug-in connection.

4. The dialyzer in accordance with claim 1, wherein the dialyzer has a control or regulation unit which is configured such that it controls or regulates the supply of the blood pressure cuff with compressed air and/or the procedure of the blood pressure measurement.

5. The dialyzer in accordance with claim 4, wherein the control or regulation unit is configured such that it controls or regulates the operation of the dialyzer.

6. The dialyzer in accordance with claim 1, further comprising at least one pressure sensor for detecting the blood pressure, with the sensor forming a component of the dialyzer or being in communication with the dialyzer such that the measured pressure value can be displayed at the dialyzer.

7. The dialyzer in accordance with claim 1, wherein the dialyzer is configured such that the data acquisition, storage and processing of the data measured by use of the blood pressure cuff takes place in the dialyzer.

8. The dialyzer in accordance with claim 1, wherein all components required for the blood pressure measurement and for the processing of the measured data are arranged in the dialyzer, with the exception of the blood pressure cuff.

9. The dialyzer according to claim 1, wherein the dialyzer is a peritoneal dialyzer.

10. A dialyzer comprising

at least one compressor,

at least one blood pressure cuff,

a pneumatic system containing at least one pneumatic consumer in communication with the compressor such that the pneumatic consumer can be acted on by compressed air supplied from the compressor, wherein the dialyzer communicates or can communicate with the at least one blood pressure cuff such that the blood pressure cuff can be supplied with compressed air by the compressor, and

at least one valve located between the compressor and the blood pressure cuff and one or more lines between the compressor and the blood pressure cuff can be closed off or released by said valve, wherein the valve is configured as a multiway valve, which is designed such that either the blood pressure cuff or other consumers are in compressed air communication with the compressor, and wherein the multiway valve is a 2-way valve.
