Abstract

A manual intravenous pump includes an input line, a fluid reservoir operatively connected to the input line, and an output line operatively connected to the fluid reservoir. The manual intravenous pump further includes a manually operable actuator, configured to facilitate the flow of fluid from the input line, through the fluid reservoir, and to the output line.

Claims

1. A manual intravenous pump comprising:

an actuator housing including a manually operable member operatively connected to a first facilitating member and a second facilitating member; and

a reservoir housing removably attached to the actuator housing, wherein the reservoir housing includes;

a first fluid input line, having a first end and a second end, the first end configured to be operatively connected to a fluid source that is external to the actuator housing and external to the reservoir housing;

a first fluid reservoir operatively connected to the second end of the first fluid input line;

a second fluid input line, having a first end and a second end, the first end configured to be operatively connected to the fluid source;

a second fluid reservoir operatively connected to the second end of the second fluid input line; and

at least one fluid output line operatively connected to the first fluid reservoir and the second fluid reservoir,

wherein the first end of the first fluid input line and the first end of the second fluid input line each remain operatively connected to the fluid source during manual actuation of the manually operable member,

wherein the first facilitating member is configured to facilitate flow of a fluid from the fluid source through the first fluid reservoir during manual actuation of the manually operable member and is further configured to cease facilitating flow of a fluid from the fluid source through the first fluid reservoir substantially upon cessation of manual actuation of the manually operable member, and

wherein the second facilitating member is configured to facilitate flow of a fluid from the fluid source through the second fluid reservoir during manual actuation of the manually operable member and is further configured to cease facilitating flow of a fluid from the fluid source through the second fluid reservoir substantially upon cessation of manual actuation of the manually operable member.

2. The manual intravenous pump of claim 1, wherein the first facilitating member is configured to operate out of phase with the second facilitating member.

3. The manual intravenous pump of claim 1, wherein the first facilitating member is configured to operate in phase with the second facilitating member.

4. The manual intravenous pump of claim 1, wherein each of the first and second reservoirs is an asymmetric diaphragm pump.

5. The manual intravenous pump of claim 1, wherein each of the first and second reservoirs is a symmetric diaphragm pump.

6. The manual intravenous pump of claim 1, wherein the manually operable member is a crank.

7. The manual intravenous pump of claim 1, wherein the manually operable member is a trigger.

8. The manual intravenous pump of claim 1, wherein the manually operable member includes at least one pivoting handle.

9. A manually operable device comprising:

at least one housing;

a first input line operatively connected to a fluid source that is external to the at least one housing;

a second input line operatively connected to the fluid source;

a first fluid reservoir operatively connected to the first input line;

a second fluid reservoir operatively connected to the second input line;

an output line operatively connected to the first fluid reservoir and the second fluid reservoir; and

a manually operable actuator, configured to facilitate a flow of fluid from the fluid source, through the first input line and second input line, through the first fluid reservoir and second fluid reservoir, and to the output line during manual operation of the manually operable actuator, and further configured to cease facilitation of the flow of fluid from the fluid source, through the first input line and second input line, through the first fluid reservoir and second fluid reservoir, and to the output line substantially upon cessation of the manual operation of the manually operable actuator, wherein each of the first and second input lines remains operatively connected to the fluid source during manual operation of the manually operable actuator.

10. The manually operable device of claim 9, wherein the manually operable actuator is a crank.

11. The manually operable device of claim 9, wherein the manually operable actuator is a trigger.

12. The manually operable device of claim 9, wherein the manually operable actuator includes at least one pivoting handle.

13. The manually operable device of claim 9, wherein the at least one housing includes a reservoir housing configured to house the first and second fluid reservoirs.

14. The manually operable device of claim 13, wherein the at least one housing further includes an actuator housing configured to house the manually operable actuator, wherein the reservoir housing is removably attached to the actuator housing.

15. The manually operable device of claim 9, wherein each of the first and second fluid reservoirs is a diaphragm pump.

16. The manually operable device of claim 9, wherein each of the first and second fluid reservoirs is defined by a cylinder.

17. The manually operable device of claim 9, wherein each of the first and second fluid reservoirs is defined by a bulb.

18. An intravenous fluid pumping kit comprising:

a fluid bag;

a fluid line; and

a pump including;

a housing;

a first fluid reservoir having a first fluid input operatively connected to the fluid bag, and a fluid output;

a second fluid reservoir having a second fluid input line operatively connected to the fluid bag, the second fluid reservoir being further connected to the fluid output; and

means for facilitating flow of fluid through the first and second fluid reservoirs from the fluid bag, through the first and second fluid inputs, and to the fluid output,

wherein the fluid bag is external to the housing.

19. The intravenous fluid pumping kit of claim 18, wherein the pump housing includes a first housing and a second housing.

20. The intravenous fluid pumping kit of claim 18, wherein the fluid line has a first end connected to the fluid bag and a second end connected to the first fluid input of the first fluid reservoir.

21. The intravenous fluid pumping kit of claim 18, wherein the fluid line includes a fluid input line and a fluid output line.

22. The intravenous fluid pumping kit of claim 21, wherein the fluid input line has a first end connected to the fluid bag and a second end connected to the first fluid input of the first fluid reservoir, and wherein the fluid output line has a first end connected to the fluid output of the first fluid reservoir.
