Abstract

A manually operable pump includes a fluid line operatively connected to a fluid source, and a manually operable actuator. A facilitator is used to facilitate flow of fluid from the fluid source through the fluid line. The facilitator is operably connected to the manually operable actuator. A piezoelectric system is operably connected to the manually operable actuator, and configured to capture energy from manual actuation of the manually operable actuator and regulate the speed of the facilitator.

Claims

1. A manual intravenous pump comprising:

a first housing having at least one roller disposed therein, the at least one roller being configured to engage a fluid line to facilitate flow of a fluid therethrough;

a second housing having;

a manually operable actuator; and

a piezoelectric system operably connected to the manually operable actuator and operably connected to the at least one roller, wherein the piezoelectric system captures energy supplied by manual actuation of the manually operable actuator, and wherein the piezoelectric system employs the captured energy to regulate a speed at which the at least one roller rotates.

2. The manual intravenous pump of claim 1, wherein the fluid line is disposed inside the first housing, wherein the fluid line has a first end connected to a first aperture of the first housing and is configured to be connected to an input line, and wherein the fluid line has a second end connected to a second aperture of the first housing and is configured to be connected to an output line.

3. The manual intravenous pump of claim 1, wherein the first housing has a slot configured to receive the fluid line, wherein the fluid line has a first end connected to a fluid source.

4. The manual intravenous pump of claim 1, wherein the at least one roller includes a plurality of rollers configured to engage opposing sides of a fluid line.

5. The manual intravenous pump of claim 1, wherein the at least one roller includes an elongated rotary device having a plurality of sections configured to engage a fluid line at a plurality of locations.

6. The manual intravenous pump of claim 1, wherein the piezoelectric system is configured to dissipate the captured energy after cessation of manual actuation of the manually operable actuator.

7. The manual intravenous pump of claim 1, wherein the piezoelectric system includes at least one piezoelectric crystal.

8. A manually operable pump comprising:

a fluid line operatively connected to a fluid source;

a manually operable actuator;

means for facilitating a flow of fluid from the fluid source through the fluid line, the means for facilitating being operably connected to the manually operable actuator; and

a piezoelectric system operably connected to the manually operable actuator, configured to capture energy from manual actuation of the manually operable actuator and regulate a speed of the means for facilitating.

9. The manually operable pump of claim 8, further comprising a fluid reservoir operably connected to the fluid line.

10. The manually operable pump of claim 8, wherein the manually operable actuator is a crank.

11. The manually operable pump of claim 8, wherein the manually operable actuator is a trigger.

12. The manually operable pump of claim 8, wherein the manually operable actuator includes at least one pivoting handle.

13. The manually operable pump of claim 8, wherein the means for facilitating includes at least one peristaltic roller.

14. The manually operable pump of claim 8, further comprising a housing.

15. The manually operable pump of claim 14, wherein the fluid source is external to the housing.

16. An intravenous fluid pumping kit comprising:

a fluid bag;

a fluid line; and

a pump including;

a housing;

at least one roller configured to engage the fluid line, wherein rotation of the at least one roller facilitates a flow of fluid through the fluid line;

a manually operable actuator operably connected to the at least one roller, such that manual actuation of the manual operable actuator causes the at least one roller to rotate; and

a piezoelectric system operably connected to the manually operable actuator and operably connected to the at least one roller, wherein the piezoelectric system captures energy supplied by manual actuation of the manually operable actuator, and wherein the piezoelectric system employs the captured energy to regulate a speed at which the at least one roller rotates.

17. The intravenous fluid pumping kit of claim 16, wherein the housing includes a first housing and a second housing.

18. The intravenous fluid pumping kit of claim 16, wherein the housing includes a slot configured to receive the fluid line.

19. The intravenous fluid pumping kit of claim 16, wherein the fluid line includes a first fluid line disposed inside the housing, and a second fluid line external to the housing and operably connected to the first fluid line.
