Fluid delivery and measurement systems and methods
View Patent ↗Fluid delivery and measurement systems and methods are disclosed.
1. A device, comprising:
(1) a housing having an interior and an exterior;
(2) a flexible member within the interior of the housing and mechanically coupled to the housing, the flexible member forming first and second chambers within the interior of the housing;
(3) a fluid reservoir within the first chamber of the housing; and,
(4) a microprobe extending from the fluid reservoir, through the flexible member and into the second chamber of the housing, the microprobe being configured to translate in a first direction and rotate substantially freely in plane perpendicular to the first direction.
2. The device of claim 1 , wherein a first end of the microprobe is in the fluid reservoir and a second end of the microprobe is capable of extending to the exterior of the housing.
3. The device of claim 1 , wherein the microprobe is mechanically coupled to the flexible member.
4. The device of claim 1 , wherein the microprobe comprises a needle.
5. The device of claim 1 , wherein the microprobe comprises a microneedle.
6. The device of claim 1 , wherein the flexible member comprises a septum.
7. The device of claim 1 , further comprising a pump in fluid communication with the fluid reservoir.
8. The device of claim 7 , wherein the pump is configured to draw a fluid from the microprobe into the fluid reservoir.
9. The device of claim 7 , wherein the pump is configured to deliver a fluid from the fluid reservoir to the microprobe.
10. The device of claim 9 , wherein the pump comprises a gas generating source.
11. The device of claim 9 , wherein the pump comprises an electrochemical cell.
12. The device of claim 7 , wherein the pump comprises a gas generating source.
13. The device of claim 7 , wherein the pump comprises an electrochemical cell.
14. The device of claim 1 , wherein the device comprises a second device for delivering a fluid from the fluid reservoir to the exterior of the device via the microprobe.
15. The device of claim 1 , wherein the device comprises a second device for delivering a fluid to the fluid reservoir from the exterior of the device via the microprobe.
