The puncture-preventing lancet according to the embodiment of the present utility model is described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the puncture-preventing lancet according to the embodiment of the present utility model, which is convenient to fix, includes a receiving seat 10 and a needle body 20.

The storage seat 10 comprises a storage tube 11, a handle 12 and an elastic piece 13, wherein the handle 12 is arranged on the outer wall of the storage tube 11, the elastic piece 13 is arranged in the storage tube 11, and the handle 12 and the elastic piece 13 are both positioned at the right end of the storage tube 11.

The storage tube 11 is a circular tube, the left end and the right end are mutually communicated, a circular channel is arranged inside the storage tube, the right end of the outer wall of the storage tube 11 is provided with a handle 12, medical staff can pinch the handle 12 to control the movement of the storage tube 11, the right end of the inside of the storage tube 11 is provided with an elastic piece 13, and the elastic piece 13 can be a spring and has certain elasticity.

The needle body 20 comprises a needle tube 22 and a needle head 21, the needle tube 22 is movably arranged in the accommodating tube 11 and can be locked by the handle 12, and the needle head 21 is arranged at the right end of the needle tube 22 and penetrates out from the right end of the accommodating tube 11; when the lock of the needle tube 22 by the handle 12 is released, the elastic member 13 urges the needle tube 22 to move leftward along the housing tube 11, so that the needle 21 is retracted from the outside of the housing tube 11 to the housing tube 11 portion.

Specifically, the needle tube 22 is inserted into the circular channel inside the storage tube 11 from the left end of the storage tube 11, can slide left and right in the circular channel, and can rotate in the circular channel, the right end of the needle tube 22 is connected with the needle 21 for blood collection, when the needle tube 22 moves to the limit position of the right end in the storage tube 11, the right end of the needle tube 22 can abut against the elastic piece 13 in the storage tube 11 and compress the elastic piece 13 to store the elastic piece 13, and the needle 21 can be inserted out from the right end of the storage tube 11 so as to be exposed outside the storage tube 11, and meanwhile, the needle tube 22 is fixed by the handle 12 on the storage tube 11, so that the needle tube 22 and the storage tube 11 are mutually fixed, and thus, a medical staff can pinch the handle 12 to control the insertion of the needle 21 into a blood vessel of a patient for blood collection. When the blood drawing is completed, the medical staff is holding the handle 12 to control the needle 21 to be pulled out from the blood vessel, and the needle 21 is still exposed outside the storage tube 11, so that the risk of accidental stabbing of the medical staff exists. At this time, medical staff can manually release the locking of handle 12 to needle tubing 22, thereby the elastic force is produced to the elastic component 13 of holding force and is produced thrust to needle tubing 22 left for needle tubing 22 moves from the right-hand member of holding tube 11 to the left, and in the in-process that needle tubing 22 moved, syringe needle 21 also can follow the removal, thereby automatic from holding tube 11 outside and shrink to holding tube 11 in, so, just so can hide syringe needle 21 in holding tube 11, holding tube 11 can not expose outside, and then just does not have the risk of stabbing medical staff, is favorable to using.

According to the puncture-proof blood taking needle convenient to fix, the needle head 21 can be hidden, so that the needle head 21 is prevented from being exposed to the outside to accidentally puncture medical staff, and meanwhile, the puncture-proof blood taking needle is convenient to fix on the skin of a patient during blood drawing, and the needle head 21 is prevented from slipping.

Advantageously, in one embodiment of the present utility model, a needle handle is provided on the outer wall of the needle cannula, and the handle 12 is removably coupled to the needle handle 221 to lock the needle cannula 22.

Preferably, an avoidance port 111 is disposed in the middle of the outer wall of the accommodating tube 11, and the avoidance port 111 extends along the length direction of the accommodating tube 11, so as to avoid the needle handle 221.

Therefore, the needle handle on the outer wall of the needle tube can be detachably connected with the handle on the storage tube, so that the needle tube is fixed through the handle, and the needle head and the storage tube are kept relatively fixed, so that medical staff can pinch the handle and the needle handle to control the needle head to penetrate into blood vessels when blood is collected. And when blood sampling is accomplished, make needle handle and handle mutually separate in order to release the locking to the needle tubing, owing to set up on the storage tube and dodge mouthful 111 to make the needle tubing can drive the needle handle and move from right to left at the storage tube outside, so as to ensure that the needle tubing can remove the left end to the storage tube and make the syringe needle shrink to the storage tube inside hide.

Advantageously, in another embodiment of the present utility model, a resilient locking block 222 is further included, said resilient locking block 222 being disposed on said needle cannula 22; the elastic locking block 222 locks the needle tube 22 in the receiving tube 11 when the elastic member 13 urges the needle tube 22 to the left end of the receiving tube 11.

Preferably, a locking groove 112 is provided at the left end of the inner wall of the receiving tube 11, and when the needle tube 22 moves to the left end of the receiving tube 11, the elastic locking block 222 is locked in the locking groove 112 to lock the needle tube 22.

When the elastic piece 13 drives the needle tube 22 to move to the left end along the containing tube 11, the needle 21 can be contracted into the containing tube 11, at this time, the needle tube 22 and the containing tube 11 are movably connected, so if the needle tube 22 is acted by external force, the needle 21 still can slide out of the containing tube 11, in order to avoid the phenomenon, a groove body is arranged at the left end of the bottom of the needle tube 22, an elastic locking block 222 is arranged in the groove body, meanwhile, a locking groove 112 is arranged at the left end of the inner wall of the containing tube 11, and therefore, when the needle tube 22 moves to the left end from the right end along the containing tube 11, the elastic locking block 222 can be ejected out of the groove body and clamped into the locking groove 112, so that the needle tube 22 is limited, and even if the needle tube 22 is acted by external force, the needle tube is not shifted, thereby being beneficial to hiding the needle 21.

Advantageously, in some embodiments of the utility model, the upper surface of the handle 12 is provided with a first adhesive layer 121, the first adhesive layer 121 being used for adhesively securing the needle handle 221.

Preferably, a stopper 122 is provided on the upper surface of the handle 12 at the left side of the first adhesive layer 121, and the stopper 122 is used for blocking the needle handle 221.

The first adhesive layer 121 may be a double faced adhesive tape, and release paper is provided on the double faced adhesive tape, when the needle 21 is required to be used for blood drawing, the needle tube 22 can be moved rightward along the storage tube 11, the needle 21 is penetrated out from the right end of the storage tube 11, then the release paper is torn off, the needle handle 221 on the needle tube 22 is adhered to the first adhesive layer 121 for fixing, and the needle handle 221 can be blocked by the stop block 122 and is not easy to slide, so that a medical staff can pinch the handle 12 and the needle handle 221 to control the needle 21 for blood drawing.

Advantageously, in further embodiments of the present utility model, the lower surface of the handle 12 is provided with a second adhesive layer 123, the second adhesive layer 123 being used to adhere the handle 12 to the skin of a patient.

Similarly, the second adhesive layer 123 may be a double sided tape, and release paper is provided on the double sided tape, so that when the needle 21 is used for blood collection, the release paper on the second adhesive layer 123 can be torn off, and then the second adhesive layer 123 is adhered to the skin around the puncture opening, so that the needle 21 can be fixed, and the needle 21 is ensured not to shift in the blood collection process.
