PCT No. PCT/SE88/00002 Sec. 371 Date Jul. 10, 1989 Sec. 102(e) Date Jul. 10, 1989 PCT Filed Jan. 12, 1988 PCT Pub. No. WO88/05286 PCT Pub. Date Jul. 28, 1988.Equipment suited for taking fluid samples from patients includes a sample taking device which is provided with a front needle (2) and a rear needle (3) whose pointed ends face away from one another. The pointed end of the front needle (2) is intended for piercing a vein or like blood vessel, while the pointed end of the rear needle (3) is intended for piercing a sealing stopper of a vacuum-type test tube capable of being partially inserted into the sampling device. Defined between the mutually facing ends of respective needles is a space (9) which accommodates a flow regulator (10) for regulating the flow through the needles. The sample taking equipment is characterized in that it also includes a protective casing which is intended to accommodate the simple taking device and which includes a cover part (22) which protects the front needle point and a cover part (20) which co-acts with the flow regulator (10) in a manner such as to hold the flow passage through the needles (2,3) open when the sample taking device is introduced into the protective cover. |
