Abstract

The invention belongs to the field of medical apparatuses, and discloses an anti-stabbing injector. The anti-stabbing injector comprises a syringe cylinder, a syringe needle, a piston located in the syringe cylinder, and a covering piece, wherein a rubber head is arranged on the syringe cylinder; the syringe needle comprises a syringe seat, a syringe stem and a syringe point which are sequentially connected; the syringe seat is connected with the rubber head; the covering piece comprises a syringe cap section which can be arranged on the syringe stem in a sleeving manner and can move in the axial direction of the syringe stem; a cavity is formed in the syringe cap section; an elastic piece is arranged in the cavity; and the elastic piece is arranged on the syringe needle in a sleeving manner, and under a reset state, the syringe point can be closed. According to the anti-stabbing injector disclosed by the invention, the syringe needle is closed through the elastic piece; and besides, a sliding section adopts a wedge-shaped structure, and the distance between the syringe cylinder and the syringe seat is enlarged, so that the syringe needle and the covering piece are simultaneously separated from the syringe cylinder, the situation that after the injector is used, when the syringe needle is drawn out, a patient is stabbed by the syringe needle and is infected is avoided, the syringe needle is avoided from being repeatedly used, the effect of preventing stabbing is realized, the safety is high, the protective effect is good, the structure is simple and reasonable, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a syringe assembly, in particular to a stab-proof syringe. Background technique [0002] Disposable syringes are one of the most widely used devices in medical institutions and the most common medical items in nursing work. However, the needles of the syringes are sharp, and the nurses are often stabbed when using or operating, for example, when pulling out the needles, bending the needles, destroying the shape, and putting the needle barrel into the sharps box. [0003] Needlestick injury is the most common accident in clinical work. It is highly harmful and has serious consequences. It will cause the spread of a variety of blood-borne diseases and have a great impact on the physical and mental health of needlestick injuries. For example, accidental needlestick injuries make healthcare workers highly susceptible to blood-borne diseases such as AIDS, hepatitis B, and C. [0004] Th...
