Resuscitator device

1. A resuscitator bag for providing positive pressure ventilation to patients, the resuscitator bag comprising:

an upper plate;

a lower plate hingedly coupled to the upper plate;

a bellows disposed between the upper plate and the lower plate;

at least one biasing member configured to move the upper plate and the lower plate apart;

a valve assembly comprising an inlet valve and an outlet valve;

wherein the valve assembly is in fluid communication with an interior chamber defined by the upper plate, the lower plate and the bellows;

an indicator that gives an indication when the resuscitator bag has been sufficiently inflated; and

a regulated inlet port fluidly connected to the bellows, the regulated inlet port is adjustable from the exterior of the resuscitator without opening the bellows, wherein the regulated inlet port comprises an adjustable valve assembly configured to control a flow rate of environment air through the inlet port and into the bellows, wherein the adjustable valve assembly controls a fill time of the bellows.

2. The resuscitator bag of claim 1 , wherein the indicator provides the indication when the resuscitator bag reaches an expanded configuration.

3. The resuscitator bag of claim 1 , wherein the upper plate further comprises a cavity for securing a tube and mask.

4. The resuscitator bag of claim 1 , further comprising a maximum inlet port fluidly connected to the resuscitator bag that is configured to allow air to freely enter the resuscitator bag.

5. The resuscitator bag of claim 1 , wherein the adjustable valve assembly is configured to adjust the fill time of the bellows by changing the size of an inlet port opening.

6. The resuscitator bag of claim 1 , wherein at least a portion of the adjustable valve assembly is configured to rotate to change the size of the opening.

7. The resuscitator bag of claim 1 , wherein the fill time is at least approximately 3 seconds and/or less than or equal to approximately 7 seconds.

8. The resuscitator bag of claim 1 , wherein the fill time is at least approximately 3 seconds and/or less than or equal to approximately 4 seconds.

9. The resuscitator bag of claim 1 , wherein a volume of the interior chamber when the resuscitator bag is in an expanded configuration is at least approximately 100 milliliters and/or less than or equal to approximately 800 milliliters.

10. The resuscitator bag of claim 1 , wherein a volume of the interior chamber when the resuscitator bag is in an expanded configuration is at least approximately 300 milliliters and/or less than or equal to approximately 400 milliliters.

11. The resuscitator bag of claim 1 , wherein the at least one biasing member comprises at least one spring functionally linked to the upper plate and the lower plate.

12. The resuscitator bag of claim 11 , wherein the bellows contains at least one support structure attached to the bellows and which is generally parallel to the upper and lower plates.

13. The resuscitator bag of claim 1 , further comprising at least one volume limiter which can be engaged to limit the volume of air which the bellows will deliver.

14. The resuscitator bag of claim 1 , further comprising a selector configured with settings corresponding to respective volumes wherein a change in setting on the selector will change the volume of air which the bellows will deliver.

15. A resuscitator bag for providing positive pressure ventilation to patients, the resuscitator bag comprising:

an upper plate;

a lower plate hingedly coupled to the upper plate;

a bellows disposed between the upper plate and the lower plate;

at least one biasing member configured to move the upper plate and lower plate apart;

a valve assembly comprising an inlet valve and an outlet valve; and

a regulated inlet port fluidly connected to the bellows, the regulated inlet port is adjustable from the exterior of the resuscitator without opening the bellows, wherein the regulated inlet port comprises an adjustable valve assembly configured to control a flow rate of environment air through the inlet port and into the bellows, wherein the adjustable valve assembly controls a fill time of the bellows;

wherein a fill time at which the resuscitator bag moves from a compressed configuration to an expanded configuration corresponds to a ventilation rate for the patient.

16. The resuscitator bag of claim 15 , further comprising an indicator that provides an indication when the resuscitator bag has been sufficiently inflated.

17. A method of providing assisted breathing to a patient, the method comprising:

manipulating an adjustable valve assembly to control a flow rate of environment air through an inlet port of a resuscitator bag, wherein the adjustable valve assembly is adjustable from the exterior of the resuscitator bag without opening the bellows, wherein the adjustable valve assembly controls a fill time of the bellows;

placing a mask on the patient, the mask being in fluid communication with a resuscitator bag;

moving the resuscitator bag to a compressed configuration to provide the patient with air; and

releasing the resuscitator bag and waiting for the resuscitator bag to give an indication that it has been sufficiently inflated and is ready to be compressed before moving the resuscitator bag to the compressed configuration again.

18. The method of claim 17 , further comprising the step of selecting a biasing member depending on the patient's size and connecting the biasing member to the resuscitator bag.

19. The method of claim 17 , wherein waiting for the resuscitator bag to reach an expanded configuration comprises observing an indicator for notification that the resuscitator bag has reached the expanded configuration.

20. The resuscitator bag of claim 15 , further comprising an inlet port regulator which can adjust the fill time at which the resuscitator bag moves from a compressed configuration to an expanded configuration.
