Abstract

A quick connection system between an anesthesia respiration system and an absorber has a gas-tight connection between the anesthesia respiration system and the absorber. The absorber (1) has a concentrically arranged gas inlet opening (8) and a gas outlet opening (9) on its front side (4) for this purpose, as well as a guide plate (3) that can be pushed into an absorber mount at the anesthesia respiration system. Centering notches (11, 12), which engage a centering pin at the absorber mount, are provided at the guide plate (3) in the direction of pushing in.

Claims

1. An anesthesia respiration system to absorber connection device, comprising:

an absorber that can be connected with the anesthesia respiration system, the absorber having an absorber housing, with a gas inlet opening concentrically arranged relative to a gas outlet opening on a front side said absorber housing, as well as a guide plate;

an anesthesia respiration system absorber mount, said guide plate being adapted to be pushed into said absorber mount;

a centering notch provided on a front side of said guide plate in the direction of pushing in; and

a centering pin, which engages the centering notch and fixes the guide plate in an end position, said centering pin being fastened to said absorber mount.

2. A device in accordance with claim 1, wherein the guide plate has another centering notch arranged offset form said centering notch by 180°

.

3. A device in accordance with claim 1, wherein the guide plate has lateral surfaces with flattened portions along the direction of pushing in.

4. A device in accordance with claim 1, wherein the centering notches have wall surfaces, which have a wedge-shaped design and receive the centering pin.

5. A device in accordance with claim 1, wherein said centering pin has an upper part, which can perform a stroke movement and is under spring tension.

6. A device in accordance with claim 5, wherein locking grooves, at least partially receiving said upper part, are present at the centering notches.

7. A device in accordance with claim 6, wherein said entry bevels for the upper part are arranged upstream of the locking grooves.

8. An anesthesia respiration system to absorber quick connection system, comprising:

an absorber having an absorber housing, with a gas inlet opening concentrically arranged relative to a gas outlet opening on said absorber housing, and a guide portion;

an anesthesia respiration system absorber mount, said guide portion being adapted to be pushed into said absorber mount;

a centering notch provided on a front side of said guide portion with respect to a direction of pushing said absorber guide portion into said absorber mount; and

a centering pin, which engages the centering notch and fixes the guide plate in an end position, said centering pin being fastened to said absorber mount.

9. A connection system in accordance with claim 8, wherein the guide plate has another centering notch arranged offset form said centering notch by 180°

.

10. A connection system in accordance with claim 8, wherein the guide plate has lateral surfaces with flattened portions along the direction of pushing in.

11. A connection system in accordance with claim 8, wherein the centering notches have wall surfaces, which have a wedge-shaped design and receive the centering pin.

12. A connection system in accordance with claim 8, wherein said centering pin has an upper part, which can perform a stroke movement and is under spring tension.

13. A connection system in accordance with claim 12, wherein locking grooves, at least partially receiving said upper part, are present at the centering notches.

14. A connection system in accordance with claim 13, wherein said entry bevels for the upper part are arranged upstream of the locking grooves.
