Abstract

Blood collecting and processing container and a storage cap member assembly, by which blood specimens may be collected, stored, transferred, processed, and the blood constituents analyzed, without transfer to other containers, and providing other advantages of convenience, savings of time and effort, and attaining other advantages while avoiding certain disadvantages of prior art equipment for this use.

Claims

1. Blood collecting and processing means comprising:

a container member having a storage chamber and an open ended capillary tube;

the bore of said storage chamber being of substantially greater size than the bore of said capillary tube;

said container means including a tapered hollow neck portion extending outwardly of said storage chamber and connecting said capillary tube to said storage chamber;

said container member being closed at the end thereof remote from said capillary tube;

means on said container member for providing easy separation of said capillary tube and neck portion from said storage chamber;

opening mEans in the side wall of said container member for forming a vent;

said opening means being located in said container member at a point farther remote from said closed end than is said separation means.

2. The invention as set forth in claim 2 in a combination in which the vent opening means is provided in the portion thereof adjacent the intersection of the storage chamber and the neck portion.

3. The invention as set forth in claim 2, and including an elongated cap member having sidewalls and a closed end;

said cap member being configured to provide an effective sealing engagement with said container member in covering relation with the open end of said capillary tube and also the said vent opening of said container member, whereby said cap member provides a storage container and a cover cap for said container member.

4. The invention as set forth in claim 1 in a combination in which the container separation means comprises a score providing for conveniently breaking said capillary tube and neck portion from said storage chamber.

5. The invention as set forth in claim 4, and including an elongated cap member having sidewalls and a closed end;

said cap member being configured to provide an effective sealing engagement with said container member in covering relation with the open end of said capillary tube and also the said vent opening of said container member, whereby said cap member provides a storage container and a cover cap for said container member.

6. The invention as set forth in claim 1, and including an elongated cap member having sidewalls and a closed end;

said cap member being configured to provide an effective sealing engagement with said container member in covering relation with the open end of said capillary tube and also the said vent opening of said container member, whereby said cap member provides a storage container and a cover cap for said container member.

7. Blood collecting and processing means comprising:

a container member having a storage chamber and an open ended capillary tube;

the bore of said storage chamber being of substantially greater size than the bore of said capillary tube;

said container member including a tapered hollow neck portion extending outwardly of said storage chamber and connecting said capillary tube to said storage chamber;

said container member being closed at the end thereof remote from said capillary tube;

there being also provided an elongated cap member having sidewalls and a closed end;

said cap member being configured to provide an effective sealing engagement with said container member in covering relation with the open end of said capillary tube and also the said vent opening of said container member, whereby said cap member provides a storage container and a cover cap for said container member;

in a combination in which said cap member is formed to include resiliently flexible material by which the cap member, by a sequence of force and a releasing thereof, provides an operative drawing of material outwardly of said neck and capillary tube and into the storage chamber of the cap member.

8. The invention as set forth in claim 7 in a combination in which the inner wall of the cap member adjacent its open end is provided with an inwardly-projecting circumferentially-extending ring which sealingly engages said container.
