Device with an anesthesia respiration system and an absorber
View Patent ↗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.
1. An anesthesia respiration system to absorber connection device, comprising:
an absorber for connecting 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 of 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 a 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 from 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 2 , 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 2 , 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 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 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 from 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 9 , 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 9 , 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 entry bevels for the upper part are arranged upstream of the locking grooves.
