    Abstract: PCT No. PCT/GB95/01894 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Aug. 10, 1995 PCT Pub. No. WO96/05879 PCT Pub. Date Feb. 29, 1996A fluid handling device has a needle retraction assembly which brings about the retraction of a hollow needle after use. A hollow body portion is provided at one end, with an end wall having a mounting portion including a needle passage. A hollow needle having a leading end portion is movable between a first position in which the leading end portion of the needle protrudes from a front end portion of said mounting portion and a second position in which the needle is withdrawn within the hollow body portion. A spring acts to bias the needle into the second, withdrawn position. The needle is provided with a portion of enlarged diameter at a location spaced from the leading end portion. A retainer maintains the needle in its first position until use is completed. The retainer includes an O-ring positioned in a circumferential groove in the portion of enlarged diameter. The O-ring abuts the end of a sleeve slidable within the mounting portion and which can be forced forwardly to dislodge the O-ring so as to permit the needle to move from its first position into its second position under the influence of the spring.

    Abstract: There is disclosed a vial having a cap ordinarily closed by a one-way valve and capable of being engaged by the barrel of a hypodermic syringe to enable the syringe to be charged with fluid from the vial when inverted. Preferably the one-way valve is a spring-pressed ball. Preferably the cap is externally screw threaded to mate with a screw threaded syringe. The arrangement minimises contamination for multi-dose vials without the possibility of the syringe being contaminated with latex.

    Abstract: Syringe (1) with retractable needle (10) has a needle (10) m ovable from the working position to the engaged position inside o f the cylinder (4), whilst the handle (8) is equipped with the co mpression spring (28) to press the needle (10) to the engaged pos ition. The needle (10) is placed in the socket (18) placed in the handle (8), which is equipped with the ring (20) positioned in a groove (19) of the socket (18) and abutting the end of a dislodg eable sleeve (36), which during the move to the front removes the ring (20) from the groove (19) and permits a retraction of the n eedle (10) with the socket (18) into the piston (6) under the inf luence of the spring (28).
