FIELD: medical equipment. ^ SUBSTANCE: blocking mechanism is used for controlling interaction of parts of sharp medical instruments as hypodermic injection syringes. Blocking mechanism has stop for holding sharp medical instrument and connector. Stop has first profiled part made for mutual engagement with second profiled part disposed on case part of sharp medical instrument. Connector is made for motion relatively mentioned case part to position at which connector and stop are mutually engaged. Connector is made for change in relative engagement force between first and second profiled parts at movement to mentioned position of mutual engagement which fact provides ability of disconnecting of stop from case part. Lock has two flexible feet, which are connected together by their ends. First profiled part is placed onto each foot. Connector is capable of bending feet when being engaged with stop to move the feet to meet each other. ^ EFFECT: reliable engagement; simplified design; compactness. ^ 41 cl, 12 dwg |
