DEVICE FOR COMPRESSING TUBE

摘要

PURPOSE: To prevent the leaking of a fluid even after the withdrawal of a hypodermic injection needle without leakage between sampling and injection treatment by providing a compressor with a port for allowing the insertion of the hypodermic injection needle into a tube with a part of the tube held by the compressor being partially exposed. CONSTITUTION: A compressor 159 keeps at least a part of a wall part of a tube 146 compressed to allow an access by an injection needle with a self-sealing function applied of the wall of the tube 146. This device 159 has an upper compression plate 160 and a lower compression plate 162 and these plates 160 and 162 have a smaller diameter in the cross section than the outer diameter in that of the tube 146 when assembled. With a flange 164, the plates 160 and 162 can be fixed by an adhesion or the like and a port 166 is formed at the center of the upper plate 160. The port 166 is so arranged to expose the tube 146 thereby preventing leakage even after the withdrawal of the injection needle.
