Injection valve, which has a housing (1) with a passage (2) for medical fluids or body fluids and attached to the passage, across through the housing's wall an itinerary channel (3) for injection of other medical fluids in the passage or for removal of fluids samples from the passage, which lateral channel has a shutting device (9). The lateral channel's (3) opening on the housing's outside is created by an upright tube's (7) free end (8) and the shutting device is created by a stretched elastic membrane (9) covering the tube's free end, that at a distance from the tube reclining section is tightly fitted to the housing around the tubing and at one point on the free section of the tubing has a self-tightening puncture (12), which membrane (9) is transverse through the self-puncture depressible over the tubing, past its free end, for release of this end, so that accessibility is achieved to the mentioned lateral channel for injection or sampling.<IMAGE> |
