Abstract

A breathing gas-carrying patient connection (2) for the artificial respiration of a patient (1) by an anesthesia apparatus or respirator (3) with one or more sensors (9, 10, 11) for detecting patient-relevant measured variables and with a telemetric transmission of the sensor data from the patient connection (2) to a machine-side connection element (13) for the patient connection (2), wherein the telemetric transmission of the sensor data is designed for wireless bidirectional communication between the patient connection (2) and the connection element (13), makes possible the reliable transmission of data into the machine-side connection element (13).

First claim

What is claimed is:

1. A patient connection arrangement for artificial respiration of a patient with an anesthesia apparatus or respirator having a machine-side connection element, the patient connection arrangement comprising:
a patient connection for applying to an air passage of the patient, where the patient connection includes a tube;
one or more sensors located on said patient connection for measuring patient-relevant variables;
a telemetric transmission means for telemetrically transmitting said patient-relevant variables from said patient connection to said machine-side connection element such that said anesthesia apparatus or said respirator receives said patient-relevant variables, said telemetric transmission means being in bidirectional communication with said patient connection and said machine-side connection element;
an energy storage arranged on said patient connection and being configured to store energy when said telemetric transmission means are connected to said anesthesia apparatus or respirator, and providing energy when said telemetric transmission means are interrupted; and
a data storage arranged on said patient connection and being configured to store sensor data, said sensor data including variable information and static data, said data storage being integrated with said telemetric transmission means and configured to be part of transferring of data between the patient connection and the anesthesia apparatus or respirator, the transferring also going through the telemetric transmission means, said sensor data including patient-relevant variables information on patient data measured by said one or more sensors during a time period during which said telemetric transmission means was interrupted;
wherein the energy storage and the data storage are located on a sidewall of the tube, and electrically connected to the telemetric transmission means and the one or more sensors.

2. A patient connection arrangement in accordance with claim 1 , wherein: said variable information includes patient data, respiration parameters and information on preparation performed in case of multiple usability of the patient connection.

3. A patient connection arrangement in accordance with claim 1 , wherein:
said static data includes one of geometric characteristics, physical characteristics, information on use, manufacturer data, manufacturing and shelf life data.

4. A patient connection arrangement in accordance with claim 1 , wherein:
said variable information includes information on preparation performed in case of multiple usability of the patient connection.

5. A patient connection arrangement in accordance with claim 1 , wherein said telemetric transmission means is designed as inductive or capacitive elements.

6. A patient connection arrangement, the patient connection arrangement comprising:
one of an anesthesia apparatus or respirator;
a patient connection including a tube having a first end configured to connect to a branch of one of the anesthesia apparatus or the respirator, said patient connection having a second end configured to apply air to a patient;
one or more sensors located on said patient connection for measuring patient-relevant variables;
a telemetric transmitter on said patient connection telemetrically transmitting said patient-relevant variables from said patient connection to the branch of the one of the anesthesia apparatus or respirator for transfer of said patient-relevant variables to the one of the anesthesia apparatus or respirator along the branch, said telemetric transmitter being in bidirectional communication with the one of the anesthesia apparatus or respirator through the branch;
an energy storage arranged on said patient connection and being configured to store energy when said telemetric transmitter is connected to said one of anesthesia apparatus or respirator, and providing energy when said telemetric transmitter is interrupted; and
a data storage arranged on said patient connection and being configured to store sensor data, said sensor data including variable information and static data, said data storage being integrated with said telemetric transmitter and configured to be part of transferring of data between the patient connection and the one of the anesthesia apparatus or respirator, the transferring also going through the telemetric transmission means, said sensor data including patient-relevant variables measured by said one or more sensors during a time period during which said telemetric transmitter was interrupted;
wherein the energy storage and the data storage are located on a sidewall of the tube, and are electrically connected to the telemetric transmitter and the one or more sensors.

7. A patient connection arrangement in accordance with claim 6 , wherein:
said variable information includes patient data.

8. A patient connection arrangement in accordance with claim 6 , wherein: said variable information includes respiration parameters.

9. A patient connection arrangement in accordance with claim 6 , wherein:
said variable information includes information on preparation performed in case of multiple usability of the patient connection.

10. A patient connection arrangement in accordance with claim 6 , wherein:
said variable information includes patient data, respiration parameters and information on preparation performed in case of multiple usability of the patient connection.

11. A patient connection arrangement in accordance with claim 10 , wherein:
said static data includes one of geometric characteristics, physical characteristics, information on use, manufacturer data, manufacturing and shelf life data.

12. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes geometric characteristics of said patient connection.

13. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes physical characteristics of said patient connection.

14. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes information on use of said patient connection.

15. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes manufacturer data of said patient connection.

16. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes manufacturing and shelf life data of said patient connection.

17. A patient connection arrangement in accordance with claim 6 , wherein:
said static data includes one of geometric characteristics, physical characteristics, information on use, manufacturer data, manufacturing and shelf life data.

18. A patient connection arrangement in accordance with claim 6 , wherein: said data storage is configured to perform data logging of the patient relevant variables measured by said one or more sensors during the time period.

19. A patient connection arrangement in accordance with claim 6 , wherein:
said sensor data includes information relating to a number of uses of said patient connection.
