Abstract

Resuscitator devices including inflation control devices and the inflation control valves can prevent an excessive number of breaths per minute during manual resuscitation from being delivered to a patient. The inflation control valves are inlet valves for a resuscitator device having a flexible chamber that extends from a first end to a second end, the second end being configured to attach to an airway adjunct. The valve housing may be configured to be disposed about the first end and to receive air for inflating the flexible chamber, the valve housing being partially disposed within the flexible chamber. The inflation control member may be configured to control inflation rate of the flexible chamber, the inflation control member being disposed within the valve housing and movable with respect to the valve housing.

Claims

1. An inlet valve for a resuscitator device having a flexible chamber that extends from a first end to a second end, the second end being configured to attach to an airway adjunct, comprising:

a valve housing configured to be disposed at the first end and to receive air for inflating the flexible chamber, the valve housing being partially disposed within the flexible chamber; and

an inflation control member configured to control a rate of inflation of the flexible chamber, the inflation control member being disposed within the valve housing and movable with respect to the valve housing.

2. The valve according to claim 1, wherein the inflation control member is configured to cause a predetermined delay between substantially full inflation and compression of the flexible chamber.

3. The valve according to claim 1, wherein the inflation control member is configured to allow the flexible chamber to inflate when the inflation control member is disposed at a first position with respect to the valve housing.

4. The valve according to claim 2, wherein the inflation control member is configured to allow maximum compression of the flexible chamber when the inflation control member is disposed at a second position with respect to the valve housing.

5. The valve according to claim 1, wherein the valve housing extends between a first end and a second end, the second end being closed.

6. The valve according to claim 5, wherein:

the inflation control member includes a spring and a platform; and

the spring is fixedly disposed to the second end and the platform.

7. The valve according to claim 5, wherein:

the valve housing includes at least a first portion and a second portion, the second portion being configured to be disposed substantially within the flexible chamber, and

the second portion including an outlet section configured to deliver air into the flexible chamber.

8. The valve according to claim 7, wherein the inflation control member is configured to allow the flexible chamber to inflate when the control member is disposed between the outlet section and the closed end of the valve housing.

9. The valve according to claim 1, wherein the inflation control member is configured to permit one maximum compression per every about 5 seconds.

10. A resuscitator device, comprising:

a flexible chamber that extends from a first end to a second end, the second end being configured to deliver air to a patient through an airway adjunct; and

an inlet valve disposed at the first end and partially disposed within the flexible chamber, the inlet valve including;

a valve housing configured to receive air for inflating the flexible chamber; and

an inflation control member configured to control a rate of inflation of the flexible chamber, the inflation control member being disposed within the valve housing and movable with respect to the valve housing.

11. The device according to claim 10, further comprising:

an airway adjunct disposed at the second end.

12. The device according to claim 11, wherein the inflation control member is configured to allow the flexible chamber to inflate when the inflation control member is disposed at a first position with respect to the valve housing.

13. The device according to claim 12, wherein the inflation control member is configured to allow maximum compression of the flexible chamber when the inflation control member is disposed at a second position with respect to the valve housing.

14. The device according to claim 10, wherein the valve housing extends between a first end and a second end, the second end being closed.

15. The device according to claim 14, wherein:

the inflation control member includes a spring and a platform; and

the spring is fixedly disposed to the second end and the platform.

16. The device according to claim 14, wherein:

the valve housing includes at least a first portion and a second portion, the second portion being configured to be disposed substantially within the flexible chamber, and

the second portion including an outlet section configured to deliver air to into the flexible chamber.

17. The device according to claim 16, wherein the inflation control member is configured to allow the flexible chamber to inflate when the control member is disposed between the outlet section and the closed end of the valve housing.

18. The device according to claim 10, wherein the inflation control member is configured to permit one maximum compression of the flexible chamber per every about 5 seconds.

19. The device according to claim 10, wherein the flexible chamber is configured to deliver 700 mL of air during a maximum compression with one hand or 1100 mL or during a maximum compression with two hands.

20. The device according to claim 10, wherein the inflation control member is configured to cause a predetermined delay between compression and substantially full inflation of the flexible chamber.
