Abstract

In an arrangement for monitoring a connection between two elements (2, 3) of a medical tubing system, preferably an artificial respiration system, a first sensor element (6) is arranged on the first of both elements (3) and a second sensor element (5) is arranged on the second of both elements (2) in the area of the connection (1). At least one sensor element (6) has at least one signal generator which generates a warning signal when both sensor elements move away from each other beyond a predetermined distance.

Claims

1. A system for monitoring a connection (1) between two tube elements (2, 3) of a medical tube conduction system said system comprising:

a first sensor element (4) provided in the region of the connection (1) on a first one of said two tube elements,

a second sensor element (6) provided in the region of the connection (1) on a second of the two tube elements,

the first sensor element (4) having at least one permanent magnet (5) generating a magnetic field,

the second sensor element (8) being a magnetic field response signal transducer formed by one of a magnetically actuable electrical contact and an electronic sensor responsive to a magnetic field,

with the second sensor element being positioned adjacent to the first sensor element and being actuated by the magnetic field of the permanent magnet of the first sensor element when the two tube elements of the medicinal tube conduction system are connected to one another, and with the second sensor element being deactivated, when the connection of two tube elements has become loose and wherein the two sensor elements (4,

     6) are separated from each other by more than a maximum predetermined amount,

a monitoring and indicating device (10) connected to the second sensor element (6) for generating at least one of an acoustic and optical alarm signal when said second sensor element (6) is deactivated.

2. A system according to claim 1, characterized by the fact that the monitoring and indicating device (10) is a device which is adapted to be arranged separate from the sensor elements (4, 6).

3. A system according to claim 1, wherein the monitoring and indicating device (10) has a housing (13) with at least one holder.

4. A system according to claim 3, wherein said at least one holder is formed of at least one attachment magnet (14) for the attachment of the housing (13).

5. A system according to claim 1, wherein the monitoring and indicating device (10) is a battery operated device.

6. A system according to claim 1, wherein the first and the second sensor elements are each firmly attached to the corresponding element (3) of the connection.

7. A system according to claim 6, wherein the first and the second sensor elements are each made in one piece with one of the two tube elements (2, 3) of the connection.

8. A system according to claim 1, wherein at least one sensor element (6) is removably attached to the corresponding tube element of the connection (1).

9. A system according to claim 1, wherein the second sensor element (6) is connected via a connecting cable (9) to an input (12) of the monitoring and indicating device (10).

10. A system according to claim 1, further comprising at least two sensor devices each comprising first and second sensor elements (4, 6) and monitoring one connection (1), said sensor devices being connected to one monitoring and indicating device (10).

11. A system according to claim 1, wherein the monitoring and indicating device (10) is an electronic system (19) which, after triggering even upon the restoration of an disturbed connection (1) and having an alarm disconnect key (18) for manually deactuating the alarm.

12. A system according to claim 1, wherein said two tube elements of the connection (1) are a Y-coupler (2) of an oxygen-supply system and a tube (3) connected with said Y-coupler.

13. A system according to claim 1, wherein said signal transducer is a reed contact (8).

14. A system according to claim 1, wherein said signal transducer is a hall sensor.

15. A system according to claim 1, wherein the second sensor element is connected with a wireless connection to an input (12) of the monitoring and indicating device (10).
