Needle protection structure and needle device

Abstract

The invention relates to the field of medical instruments, and specifically discloses a needle protection structure, a protection method and a needle device. The needle protection structure includes a needle base, a needle tube and a protection base, and the needle tube is connected to the needle base; the protection base is provided with a pinhole, and is rotatably connected to a cover plate, and the cover plate is provided with The needle passage; also includes a lock needle assembly, the lock needle assembly includes a torsion spring; the needle base has at least the following two position states relative to the protective seat: in the first position state, the needle passage is aligned with the needle hole , at this moment, the torsion spring is in the state of diastolic energy storage, and the needle tube passes through the coil, the pinhole and the needle-threading channel; in the second position state, the needle tube withdraws from the needle-threading channel, and the needle-threading channel and the needle hole are staggered. The above-mentioned needle protection structure is used to store the sharp part of the needle tube after the needle is used, so as to avoid the exposure of the sharp end of the needle tube, causing secondary injury and cross-infection, and protecting patients and medical staff.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a needle protection structure, a protection method and a needle device. Background technique [0002] Various types of needle devices are the most commonly used disposable consumables in medical institutions. The needles of traditional needle devices are usually exposed after use, which can easily cause accidental needle stick injuries and environmental pollution. Needlestick injuries and the resulting cross-infection are a safety and health problem that has plagued medical staff for a long time. After use, the pointed end of the contaminated needle tube is exposed, which is easy to cause secondary injury and cross-infection. Therefore, it is necessary to design a needle device with better safety, which can minimize the risk of secondary injury and cross-infection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a need...
