Abstract

The invention provides a puncture-preventing indwelling needle. The puncture-preventing indwelling needle comprises a catheter base, a needle file, a needle tube and a protection mechanism, wherein the needle file sleeves the catheter base in a sliding manner; the needle tube is mounted to the needle file, and the needle point can penetrate through the catheter base; the protection mechanism is arranged between the catheter base and needle file, and is composed of a protection base and a protection plate mounted on the protection base, the protection base is provided with a protection base body allowing the needle tube to pass through, and an accommodating cavity for accommodating part of the needle tube is formed in the protection base body; the protection plate is provided with a protection plate body, a baffle plate accommodated in the accommodating cavity is formed at one end of the protection plate body, the baffle plate has the first state of pushing against the needle tube and a second state of sheltering the needle point, a support structure is arranged in the accommodating cavity, the support structure applies a supporting force to the needle tube, and the direction of the supporting force is opposite to that of the resisting force applied by the baffle plate. For the puncture-preventing indwelling needle, the support structure applies the supporting force to the needle tube, the direction of the supporting force is opposite to that of the resisting force applied by the baffle plate, so that the needle tube has small possibility of deformation under the pushing and pressing of the baffle plate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-acupuncture indwelling needle. Background technique [0002] At present, ordinary indwelling needles on the market do not have the anti-puncture function. After the puncture is completed and the needle tube is pulled out, the needle tip is exposed and it is easy to stab medical staff or other related personnel, causing cross-infection. In order to solve the problem that the exposed needle tip is easy to injure people after the puncture is completed, anti-acupuncture indwelling needles have appeared on the market. [0003] Existing anti-acupuncture indwelling needles usually include a catheter base, a needle base, a needle tube, a protection base and a spring sheet. The elastic baffle that blocks the needle tip. During the use of the anti-acupuncture indwelling needle, the elastic baffle is pressed against the needle tube and does not block the needle tip. When th...
