Abstract

Devices and methods are disclosed for transferring multiple fluids from multiple supply reservoirs to multiple corresponding receptacle reservoirs. The devices and methods may be configured to prevent or reduce the incidence of a user transferring a fluid to an incorrect receptacle reservoir.

Claims

1. A fluid transfer system, comprising:

A. a first receptacle reservoir including;

(i) a first receptacle reservoir body,

(ii) a first receptacle interior volume disposed within the first receptacle reservoir body the first receptacle interior volume being capable of containing a measurable quantity of fluid, and

(iii) a first receptacle reservoir interface in fluid communication with the first receptacle interior volume;

B. a second receptacle reservoir including;

(i) a second receptacle reservoir body,

(ii) a second receptacle interior volume disposed within the second receptacle reservoir body the second receptacle interior volume being capable of containing a measurable volume of fluid, and

(iii) a second receptacle reservoir interface in fluid communication with the second receptacle interior volume;

C. a first supply reservoir including;

(i) a first supply reservoir body,

(ii) a first supply interior volume disposed within the first supply reservoir body,

(iii) a first fluid contained within the first supply interior volume, and

(iv) a first supply reservoir interface in fluid communication with the first supply interior volume and capable of coupling with the first receptacle reservoir interface in order to create a first fluid communication junction between the first supply interior volume and the first receptacle interior volume the first supply reservoir interface being mechanically incompatible with the second receptacle reservoir interface so as to prevent a fluid communication junction therebetween; and

D. a second supply reservoir including;

(i) a second supply reservoir body,

(ii) a second supply interior volume disposed within the second supply reservoir body,

(iii) a second fluid contained within the second supply interior volume, and

(iv) a second supply reservoir interface in fluid communication with the second supply interior volume and capable of coupling with a second receptacle reservoir interface in order to create a second fluid communication junction between the second supply interior volume and the second reservoir interior volume the second supply reservoir interface being mechanically incompatible with the first receptacle reservoir interface so as to prevent a fluid communication junction therebetween.

2. The fluid transfer system of claim 1 wherein a body of the first receptacle reservoir comprises a thin flexible material and a body of the second receptacle reservoir comprises a thin flexible material.

3. The fluid transfer system of claim 1 further comprising a pump device disposable cartridge and wherein the first receptacle reservoir and the second receptacle reservoir are both disposed in the pump device removable cartridge.

4. The fluid transfer system of claim 1 wherein the first supply reservoir interface is releasably secured to the first supply reservoir body and the second supply reservoir interface is releasably secured to the second supply reservoir body.

5. The fluid transfer system of claim 1 wherein the first supply reservoir interface is contiguously formed into the first supply reservoir body and the second supply reservoir interface is contiguously formed into the second supply reservoir body.

6. A method for transferring fluids, comprising:

a. creating a first fluid communication junction between a first receptacle reservoir and a first supply reservoir by coupling a first receptacle reservoir interface to a first supply reservoir interface the first supply reservoir interface being mechanically incompatible with a second receptacle reservoir interface so as to prevent a fluid communication junction therebetween;

b. transferring a first fluid from the first supply reservoir into the first receptacle reservoir through the first fluid communication junction of the first supply reservoir interface and first receptacle reservoir interface;

c. creating a second fluid communication junction between a second receptacle reservoir and a second supply reservoir by coupling the second receptacle reservoir interface to a second supply reservoir interface, the second supply reservoir interface being mechanically incompatible with the first receptacle reservoir interface so as to prevent a fluid communication junction therebetween; and

d. transferring a second fluid from the second supply reservoir into the second receptacle reservoir through the second fluid communication junction of the second supply reservoir interface and second receptacle reservoir interface.

7. The method of claim 6 wherein transferring the first fluid from the first supply reservoir into the first receptacle reservoir comprises decreasing the pressure in the first receptacle reservoir with a pump device and wherein transferring the second fluid from the second supply reservoir into the second receptacle reservoir comprises decreasing the pressure in the second receptacle reservoir with a pump device.

8. The method of claim 6 wherein transferring the first fluid from the first supply reservoir into the first receptacle reservoir comprises increasing the pressure in the first supply reservoir with a pump device and wherein transferring the second fluid from the second supply reservoir into the second receptacle reservoir comprises increasing the pressure in the second supply reservoir with a pump device.

9. The method of claim 6 wherein transferring the first fluid from the first supply reservoir into the first receptacle reservoir comprises decreasing the internal volume of the first supply reservoir with a movable plunger and wherein transferring the second fluid from the second supply reservoir into the second receptacle reservoir comprises decreasing the internal volume of the second supply reservoir with a movable plunger.

10. The method of claim 6 wherein transferring the first fluid from the first supply reservoir into the first receptacle reservoir comprises increasing the internal volume of the first receptacle reservoir with a movable plunger and wherein transferring the second fluid from the second supply reservoir into the second receptacle reservoir comprises increasing the internal volume of the second receptacle reservoir with a movable plunger.

11. A fluid transfer system, comprising:
