Abstract

Disclosed is a fluid collection device wherein multiple, individual, samples of fluid can be withdrawn simultaneously. The device includes an evacuated chamber and an adapter which substantially simultaneously distributes the blood to each individual chamber.

Claims

1. A blood collection device, comprising:

(a) an adapter including a piercing probe, a manifold in fluid communication with the piercing probe, a plenum in fluid communication with the manifold, the plenum sealed with an adapter septum; and

(b) a body having one or more evacuated chambers, each of said chambers having an aperture aligned with the piercing probe, each of said apertures sealed with a septum;

the adapter selectively movable relative to the body to pass the piercing probe through the septum and fluidly connect the plenum with the one or more evacuated chambers.

2. The blood collection device of claim 1, wherein the adapter is releasably mounted to the body.

3. The blood collection device of claim 1, further comprising a needle holder assembly for cooperating with the adapter and body.

4. The blood collection device of claim 1 wherein the body includes means for slidingly engaging the adapter.

5. The blood collection device of claim 1 comprising a plurality of chambers.

6. The blood collection device of claim 5 wherein a single septum seals the plurality of apertures.

7. The device of claim 1 further comprising means for immobilizing the adapter relative to the body for shipping.

8. A device for transferring blood from a source to an evacuated chamber, comprising:

a piercing probe, a manifold in fluid communication with the piercing probe, a plenum in fluid communication with the manifold, and a septum which seals the plenum.

9. A method of transferring blood from a source to an evacuated chamber, comprising:

(a) providing a blood transfer device comprising a piercing probe, a manifold in fluid communication with the piercing probe, and a septum which seals the manifold;

(b) penetrating the septum on the manifold to expose the piercing probe to the blood source; and

(c) passing the piercing probe through a second septum to fluidly connect the piercing probe to the evacuated chamber.

10. A blood collection device, comprising:

(a) one or more evacuated chambers, wherein in each of said one or more evacuated chambers the cross-section perpendicular to the long axis is asymmetric in shape, each of said one or more evacuated chambers having an aperture; and

(b) a septum which seals each aperture.

11. The blood collection of device of claim 10 comprising a plurality of evacuated chambers.

12. The blood collection device of claim 11 wherein each chamber is sealed with a septum.

13. The blood collection device of claim 11 wherein a single septum seals a plurality of apertures.
