Abstract

The invention discloses a stabbing prevention puncture needle. The stabbing prevention puncture needle comprises a needle holder, a needle body, a protection cover and a locking part. The needle body is fixed onto the needle holder, and the wall of the needle body is provided with a bayonet; the protection cover externally sleeves the needle body and is shorter than the needle body, and the protection cover is matched with the needle holder before accessing to a stabbing prevention state and separated from the needle holder when accessing to the stabbing prevention state; the locking part is positioned in the protection cover, the locking part and the protection cover are relatively fixed in the axial direction of the needle body, the locking part is provided with a through hole allowing the needle body to pass through and further provided with a projection towards the needle body, and in the stabbing prevention state, the projection is matched with the bayonet of the needle body to enable the locking part and the needle body to be fixed together, and the distance between the projection and one end, close to the point of the needle body, of the protection cover is larger than that between the bayonet of the needle body and the point of the needle body. The stabbing prevention puncture needle which is capable of preventing the used puncture needle from stabbing people is provided for solving the technical problem that the used puncture needle is prone to stabbing people.

Description

technical field [0001] The invention relates to a medical transfusion device. Specifically, it is a stab-proof puncture needle used for indwelling needles. Background technique [0002] At present, human transfusion has been widely used as an important and effective medical method for treating diseases. When the human body is transfused, the needle made of metal will cause pain to the patient when it is penetrated into the blood vessel of the human body. Multiple punctures are required if the disease requires multiple infusions. The indwelling needle can solve the above problems. The indwelling needle generally includes a puncture component and an infusion component. After the puncture is completed, the puncture component is separated from the human body. A part of the soft infusion needle of the infusion assembly is left in the blood vessel of the human body, and when infusion is performed next time, the infusion needle and the infusion tube can be connected for infusion...
