The latter is preferably positioned in the compartment in a coiled or stacked condition. One needle 28 extends into but not through the thickened bottom wall 23 of stopper i2, as illustrated in Figure l, the wall being recessed at 32 to receive the tube enlargement 29 upon the reception of a downward force and in order to permit the needle to extend into the sealed interior of the bottle. Vrlube 3i is of sufcient diameter to permit blood to ow therethrough and the strength of its wall structure prevents collapse in the presence of a vacuum within the bottle II.

Also positioned within the bottle and carried i with its upper end sealed in the bottom wall 23 of stopper I2, is a vertical rigid tube 33 which extends substantially to the lower end of the bottle for a reason which will be explained.

The unit construction is completed by the presence of a cup-shaped sealing cap I4 overlying the compartment 23 with its side wall enclosing the bottle neck and extended inwardly, as at 34, to underlie the lower bead I8. Within the top of cap I4 and carried thereby is a resilient sealing wafer or disc 36 which is compressed against the top surface of ring 24. Cap I4 may preferably be formed of a light, destructible metal or of a plastic and may be positioned upon the bottle in any well known manner.

The unit is sold in the sealed condition illustrated in Figure 1. The parts within the bottle are sterilized and aseptic and air has been exhausted from the bottle to create a vacuum therein. In placing the unit in use, the cap I4 is first removed and the free needle 28 withdrawn from the compartment 23. This is accomplished without actual physical contact with the needle, the operator instead grasping the enlarged end 29 of the rubber tube 3I. The needle is inserted into the patient in the usual manner and bottle II supported in a position to receive the blood. The physician or attendant then exerts a downward force upon the head of the needle 28 carried by the stopper and forces the inner end thereof into the interior of the bottle. The vacuum within the bottle is immediately `ef fective to draw blood from the patient.

Upon the bottle being lled with the predetermined quantity of blood, the inner needle 28 is drawn from the stopper I2 whereupon the natural resilience of the material instantly seals the opening and the contained fluid is insured against contamination.V The administrative kit comprising the two needles and their conduit 3i can then be discarded, having served its purpose.

In emptying the bottle, the container is preferably inverted so that the end of tube 33 within the bottle is positioned above the uid level. A hypodermic needle is then inserted through the bottom wall 23 into the end of tube 33 to provide for the entrance of air into the space above the contained fluid. A second needle is inserted through the stopper I2 at the recess 32 and the iiuid is conducted therethrough by the action of gravity.

In the described preferred embodiment the liquid-containing space within bottle Il was evacuated of all air to create a vacuumreffective to draw the blood into the bottle. The unit is usable, however, in the absence of the vacuum. In such a case, the operation previously described is applicable but with the following variation.

4 The bottle will be filled by the action of gravity and so must be placed at a level below the patient. Further, the entrance of uid will displace air from the bottle which must be permitted to escape. Accordingly a third needle would be inserted through the bottom wall 23 to permit this escape.

While the particular apparatus herein shown and described in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of my invention, and that I do not mean to limit myself to the details of construction or design herein shown, other than as defined in the appended claims.

I claim:

1. Apparatus for withdrawing and storing animal body iiuids comprising a container, a resilient stopper sealing an aperture in said container and formed with a compartment therein substantially wholly within said container, an administering set positioned in said compartment including a hypodermic needle and means to penetrate said stopper tc connect said set interiorly to the sealed interior of said container, and means sealing said compartment, whereby said apparatus in its completely assembled form may be sterilized as a unit, and said sterility maintained until the instant of inserting said hypodermic needle in a patient.

2. Apparatus for withdrawing and storing body uids comprising a container having an opening, a resilient closure in the opening of said container formed with an open-sided compartment, an administering set'including a flexible uidcarrying tube and a closure-penetrating element on the end thereof extended partially through said closure and adapted to be pressed entirely 0 therethrough so as to connect the interior of said tube with the interior of said container, and a removable closure sealing the open side of said compartment.

3. Apparatus for withdrawing and storing body fluids comprising a container having an opening, a resilient stopper sealing said opening and formed with an outwardly opening compartment, an administering set including a length of noncollapsible flexible tubing with hypodermic needles seated in its endspositioned in said compartment, one of said needles being'adapted to extend through said closure into said container, a rigid tube sealed in said closure and extended substantially to the opposite wall of said container and adapted to serve as an air conduit for incoming air upon the inversion of said container and the insertion of a third needle through said closure to open thereinto, and a removable closure sealing said compartment.

4. Apparatus for withdrawing and storing body fluids comprising a bottle having a reduced neck formed exteriorly with spaced beads, a flanged hollow rubber stopper seated in said neck in airtight `relationship and formed with a compartment therein, an administering set positioned in said compartment comprising sterile needles connected to the opposite end of a length of iiexible tubing, a sealing ring overlying said flange and the outer of said beads to secure said stopper in place, and a removable sealing cap including a sealing disc overlying said ring to close vsaid compartment in airetight relationship, said cap extending around Y.said neck to overlie the inner of said beads.
