Abstract

A collapsible reservoir system is disclosed herein. The collapsible reservoir system includes a first tube pneumatically connected to the collapsible reservoir, and a second tube pneumatically connected to the collapsible reservoir. The second tube is configured to generally remain open in the absence of an externally applied compressive force. The second tube is positioned relative to the collapsible reservoir such that a compressive force applied to the collapsible reservoir can also compress and thereby restrict the second tube. A corresponding method for controlling the pressure of a collapsible reservoir system is also provided.

Claims

1. A collapsible reservoir system comprising:

a manually collapsible reservoir filled with gas;

a first tube pneumatically connected to the manually collapsible reservoir; and

a manually collapsible second tube pneumatically connected and continuously open to the manually collapsible reservoir, said second tube configured to generally remain open in the absence of an externally applied compressive force, said second tube being positioned relative to the collapsible reservoir such that a manual compressive force applied to the collapsible reservoir simultaneously compresses and thereby restricts the second tube to increase the back pressure within the manually collapsible reservoir to direct gas from the reservoir through the first tube.

2. The collapsible reservoir system of claim 1, wherein the second tube extends generally along the length of the collapsible reservoir such that an operator can engage the second tube at a plurality of different locations and does not need to find a specific point of contact in order to restrict the second tube.

3. The collapsible reservoir system of claim 1, wherein at least a portion of the second tube is secured to an outer surface of the collapsible reservoir to increase the likelihood that a compressive force applied to the collapsible reservoir will also compress and thereby restrict the second tube.

4. The collapsible reservoir system of claim 1, wherein at least a portion of the second tube is disposed in close proximity to an outer surface of the collapsible reservoir to increase the likelihood that a compressive force applied to the collapsible reservoir will also compress and thereby restrict the second tube.

5. The collapsible reservoir system of claim 1, wherein at least a portion of the second tube is disposed about the periphery of the collapsible reservoir in a generally spiraled pattern to increase the likelihood that a compressive force applied to the collapsible reservoir will also compress and thereby restrict the second tube.

6. The collapsible reservoir system of claim 1, wherein the second tube comprises a reservoir end physically connected to the manually collapsible reservoir, and a free end that opens to the exterior of the reservoir.

7. The collapsible reservoir system of claim 6, wherein the second tube is an exhaust tube configured to release excess pressure from the collapsible reservoir system.

8. A collapsible reservoir system comprising:

a first tube pneumatically connected to an inlet hose of a patient circuit;

a manually collapsible reservoir pneumatically connected to the first tube; and

a second tube pneumatically connected and continuously open to an outlet hose of the patient circuit;

wherein the second tube is configured to generally remain open in order to release excess pressure to the exterior of the collapsible reservoir system, and wherein at least a portion of the second tube is integral with the manually collapsible reservoir such that a manual compressive force applied to the collapsible reservoir further occludes the second tube.

9. The collapsible reservoir system of claim 8, wherein the second tube comprises a plurality of tubes.

10. The collapsible reservoir system of claim 8, wherein the second tube extends generally along the length of the collapsible reservoir such that an operator can engage the second tube at a plurality of different locations and does not need to find a specific point of contact in order to restrict the second tube.

11. The collapsible reservoir system of claim 8, wherein at least a portion of the second tube is disposed in close proximity to an outer surface of the collapsible reservoir to increase the likelihood that a compressive force applied to the collapsible reservoir will also compress and thereby occlude the second tube.

12. The collapsible reservoir system of claim 8, wherein at least a portion of the second tube is disposed about the periphery of the collapsible reservoir in a generally spiraled pattern to increase the likelihood that a compressive force applied to the collapsible reservoir will also compress and thereby occlude the second tube.

13. The collapsible reservoir system of claim 8, further comprising a valve operatively connected to the first tube.

14. The collapsible reservoir system of claim 13, further comprising a fresh gas supply operatively connected to the first tube.

15. The collapsible reservoir system of claim 14, further comprising a second valve operatively connected to the second tube the second valve being adjustable to adjust the positive end expiratory pressure of the collapsible reservoir system.

16. A method for controlling the pressure of a collapsible reservoir system comprising;

providing a collapsible reservoir in fluid communication with a patient circuit;

providing a first tube in fluid communication with the patient circuit;

providing a second tube in fluid communication with the patient circuit;

compressing the collapsible reservoir and generally simultaneously compressing the second tube such that the second tube becomes occluded and creates a back pressure within the collapsible reservoir such that at least a portion of the contents of the collapsible reservoir are transferred to the patient circuit; and

releasing the collapsible reservoir after said compressing the collapsible reservoir, wherein said releasing the collapsible reservoir also opens the second tube such that excess pressure in the collapsible reservoir system can be released therethrough.

17. The method of claim 16, wherein said compressing the collapsible reservoir and generally simultaneously compressing the second tube includes manually squeezing the collapsible reservoir and generally simultaneously manually squeezing the second tube.

18. The method of claim 16, wherein said providing a second tube includes providing a second tube that extends generally along the length of the collapsible reservoir such that an operator can engage the second tube at a plurality of different locations and does not need to find a specific point of contact in order to restrict the second tube.

19. The method of claim 16, wherein the second tube comprises a free end through which the excess pressure is released to the exterior of the collapsible reservoir system.

20. The method of claim 16, wherein said providing a second tube includes providing a second tube disposed about the periphery of the collapsible reservoir in a generally spiraled pattern.
