Abstract

A body fluid collecting, transporting, and dispensing system includes a body fluid collecting receptacle and a handle for supporting the receptacle in a fluid collection position. The handle includes a fluid sample chamber in fluid communication with the receptacle to receive a sample of the body fluid and the handle is further removable from the receptacle for transport and dispensing of the body fluid sample through a tip. A flexible hollow streaker, attachable to the tip, enables streaking of fluid sample from the chamber onto an agar plate or the like.

Claims

1. A body fluid collecting, transporting, and dispensing system comprising:

a body fluid collecting receptacle;

a handle supporting the receptacle in a fluid collection position, said handle including a fluid sample chamber in fluid communication with the receptacle to receive a sample of the body fluid, said handle being removable from the receptacle for transport, storage, and dispensing of the body fluid sample;

a sample withdrawing and dispensing plunger with a head disposed in the chamber;

a tip in fluid communication with the chamber for withdrawing the fluid sample through a fitting in the receptacle and dispensing the fluid sample from the chamber; and

a flexible hollow streaker attachable to said tip to enable streaking of fluid sample from the chamber onto an agar plate or the like.

2. The system according to claim 1 wherein said handle comprises a sample withdrawing plunger with a head disposed in the chamber, and a tip for withdrawing the fluid sample through a fitting in the receptacle.

3. The system according to claim 2 wherein said plunger is removable from the head and handle and the system further comprises a tip cap to facilitate safe transport of the handle with the fluid sample.

4. The system according to claim 3 wherein the fluid sample chamber includes a rotatable stopper at an end opposite of said tip and the fluid sample chamber includes an air vent aperture, the aperture being disposed at a position exposable by rotation of the stopper in order to enable dispensing of the fluid sample through said tip with the cap removed.

5. The system according to claim 1 wherein the receptacle includes a displacement member fixed within the receptacle at a position raising a fluid sample level, within the receptacle, to the fitting.

6. The system according to claim 1 wherein said fluid communication includes a fitting through a sidewall of the receptacle and spaced apart from a bottom of the receptacle.

7. The system according to claim 6 wherein the receptacle includes a displacement member fixed within the receptacle at a position raising a fluid sample level, within the receptacle, to the fitting.

8. The system according to claim 1 wherein said handle further comprises a squeezable bulb disposed at an end of the chamber to withdraw the fluid sample into the chamber.

9. The system according to claim 1 further comprising a sealable/unsealable sidewall opening in the chamber at a spaced apart distance from said tip, unsealing of the port enabling dispensing of sample fluid through the tip.

10. The system according to claim 9 further includes separable tape member for sealing the sidewall opening.

11. The system according to claim 9 further including stretchable elastic member for sealing the sidewall opening and a mechanism for stretching the elastic member to expose the sidewall opening.

12. The system according to claim 8 wherein the bulb is removable from the chamber and a closable lid is provided to cover a top of the chamber

13. The system according to claim 12 wherein the receptacle includes a displacement member fixed within the receptacle at a position raising a fluid sample level, within the receptacle, to the fitting.

14. The system according to claim 1 further comprises a solid active reagent disposed in said chamber for dissolution by the fluid sample.

15. The system according to claim 1 further comprises a liquid active reagent disposed in said chamber for mixing with the fluid sample.

16. The system according to claim 1 wherein said fluid sample chamber initially includes a vacuum for drawing the sample from the receptacle.

17. The system according to claim 16 wherein the handle includes a vacuum tube holder.

18. The system according to claim 16 further comprises a plunger head disposed in the chamber, a removable top chamber seal and an plunger attachable to the head for dispensing of fluid sample from the chamber through a tip.

19. A body fluid collecting, transporting, and dispensing system comprising:

a body fluid collecting receptacle;

a body fluid expressor disposed in the receptacle;

a handle supporting the receptacle in a fluid collection position, said handle including a fluid sample chamber in fluid communication with the receptacle to receive a sample of the body fluid, said handle being removable from the receptacle for transport, storage, and dispensing of the body fluid sample;

a sample withdrawing and dispensing plunger with a head disposed in the chamber;

a tip in fluid communication with the chamber for withdrawing the fluid sample through a fitting in the receptacle and dispensing the fluid sample from the chamber; and

a flexible hollow streaker attachable to said tip to enable streaking of fluid sample from the chamber onto an agar plate or the like.
