Abstract

Fluid communication devices may be provided for use with intraosseous devices. Apparatus and methods may also be provided to communicate fluids with an intraosseous device.

Claims

1. A medical apparatus comprising:

a container having a first and a second compartment formed therein;

the first compartment having a configuration and dimensions compatible with a standard intravenous fluid bag;

the second compartment at least partially surrounding the first compartment;

the second compartment operable to apply force to the first compartment;

the first compartment capable of holding an internal fluid pressure of at least 1000 mm mercury in response to force applied to the first compartment by the second compartment;

a connector operable to releasably engage the second compartment with a source of fluid pressure; and

an indicator operable to display a pressure measurement of a fluid within the second compartment.

2. The medical apparatus of claim 1 wherein the medical device further comprises:

a fastener operable to releasably connect at least two portions of the container; and

the first compartment at least partially formed by operation of the fastener.

3. The medical apparatus of claim 2 wherein the fastener comprises at least one fastener chosen from the group consisting of a zipper, a hook and loop fastener, a buckle, and a clip.

4. The medical apparatus of claim 1 wherein the container further comprises a blood pressure cuff.

5. The medical apparatus of claim 1 wherein the container further comprises the container having an opening sized to allow fluid connectors to be attached to a fluid bag in the first compartment.

6. The medical apparatus of claim 1 wherein the connector further comprises at least one component chosen from the group including a one-way valve. a two-way valve, and a three way stop cock

7. The medical apparatus of claim 1 further comprising a regulator operable to control the delivery of fluid from the source of fluid pressure to the second compartment.

8. The medical apparatus of claim 7 wherein the regulator operates in association with the indicator to control the pressure of any fluid within the second compartment.

9. The medical apparatus of claim 1 wherein the indicator is operable to display pressures around up to 2000 mm Hg.

10. A medical apparatus comprising:

a container having a compartment formed therein;

the compartment having a configuration and dimensions compatible with holding an intravenous fluid bag;

a spring at least partially disposed within the container and to expand into the compartment;

a stop operable to restrict the expansion of the spring; and

a trigger operable to disable the stop.

11. The medical apparatus of claim 10 wherein the spring comprises a leaf spring.

12. The medical apparatus of claim 10 wherein the spring comprises a spiral spring.

13. The medical apparatus of claim 10 further comprising the spring:

operable to be removed from the container;

operable to be compressed; and

operable to be replaced in the container.

14. The medical apparatus of claim 10 further comprising a removable section configured to contain the spring when compressed.

15. The medical apparatus of claim 10 further comprising the spring configured to provide substantially constant force against a fluid bag in the compartment as the spring expands into the compartment.

16. The medical apparatus of claim 10 further comprising:

a fastener operable to releasably connect at least two portions of the container; and

the first compartment at least partially formed by operation of the fastener.

17. The medical apparatus of claim 10 wherein the fastener comprises at least one fastener chosen from the group consisting of a zipper, a hook and loop fastener, a buckle, and a clip.

18. The medical apparatus of claim 10 wherein the container further comprises the container having an opening sized to allow fluid connectors to be attached to any intravenous fluid bag in the first compartment.

19. A method for providing intraosseous fluid delivery comprising:

providing a container including a compartment having a configuration and dimensions compatible with holding an intravenous fluid bag;

inserting a fluid bag into the compartment;

connecting the fluid bag in fluid communication with an intraosseous device disposed at an insertion site in a patient; and

activating a force against the fluid bag to increase the fluid pressure.

20. The method of claim 19 wherein the force comprises the delivery of high pressure fluid to the container.

21. The method of claim 20 further comprising regulating the delivery of high pressure fluid to pressure around 2000 mm Hg.

22. The method of claim 19 wherein the force comprises the expansion of a spring at least partially disposed within the compartment.
