The invention discloses a disposable safety blood taking needle comprising a holding body, a needle body and a needle cap; a lateral tubular cavity used for receiving the needle body is arranged in the holding body; the needle body tip penetrates from the left end of the holding body; the needle cap wraps the tip and is detachably connected with the holding body; the holding body comprises a tearing rib, a left shell and a right shell; the upper portion of the left shell and the upper portion of the right shell are hinged via a rotary shaft; the lower portions of the left and right shells areconnected via the tearing rib; the lateral tubular cavity laterally penetrates the left and right shells; the needle body tail is fixedly connected with the left shell. The holding body of the disposable safety blood taking needle comprises the left and right shells that are mutually hinged to each other, and the tearing rib can keep the holding body stable in connection; when the blood taking needle is used, the tearing rib is dismounted so as to easily fold the left and right shells, thus bending and folding the needle body in a folding process, contracting the tip into the left shell, and effectively preventing the waste blood taking needle from causing secondary pollution.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a disposable safety blood collection needle. Background technique [0002] Existing blood collection needles have great potential safety hazards after use. This is because the needle tip will be exposed outside the holding body after the needle cap is removed. Therefore, it needs to be carefully packaged during the discarding process to avoid re-injury and secondary infection. . Contents of the invention [0003] In the disposable safety blood collection needle provided by the present invention, the holding body of the blood collection needle can be bent after the use of the blood collection needle, because the bending place will cause pressure on the middle of the needle body in the holding body, so that the needle tip is relatively The relative displacement of the body port is loosened, so that the needle tip retracts into the holding body. [0004] A disposable s...
