Description
Technical Field
The present invention relates to a needle protection structure, and more particularly to a needle protection structure with deep stability and safety.
Background
In modern medicine, it is a normal state that the treatment is carried out by injection and infusion, and the used syringe needle is usually sheathed with a sheath in real time, so as to prevent accidental puncture and infection to patients or medical staff, facilitate subsequent syringe disposal operation and prevent the syringe needle from being recycled. In addition, in medical examination, blood collection and examination are also important ways for obtaining physiological and pathological information of human bodies, so that a sheath is also required to be sleeved on the blood collection needle for venous blood collection after blood collection, so that the condition that virus cross infection is caused by accidental puncture of the needle or the blood collection needle is prevented from being recycled and used is avoided. The prior art has the patent application number as to the design of the needle head sheath structure of the injector and the blood taking needle, and the related art: 201120350499.0, 201220578676.5, 201310417227.1, 201320060383.2, 201410114478.7, 201320568812.7, 201410114477.2, 201410381297.0, 201420052270.2, 201420138326.6, and the like. The needle head protective cover structure mainly comprises an injection tube (or a blood sampling tube), a needle head seat is arranged on the injection tube, a needle head used for injection (or blood sampling) is convexly arranged on the needle head seat, a needle head cover is covered on the needle head seat and used for protecting the needle head, a safety protective cover is connected on one side of the needle head seat, a connecting mechanism (or a turnover mechanism) capable of bending is arranged on the lower section part of the safety protective cover, and the safety protective cover is in a state of being attached to one side of the needle head cover before the injection tube (or the blood sampling tube) is used; when the safety protection device is used, the safety protection sleeve is turned down by the connecting mechanism (or the turnover mechanism), then the needle head cover is taken down to expose the needle head, so that injection (or blood sampling) operation is carried out, after the injection (or the blood sampling) is finished, the safety protection sleeve is pushed to be bent and closed in the direction of the needle head, an elastic mechanism is connected below the connecting mechanism (or the turnover mechanism), the elastic mechanism is used for facilitating the automatic sheathing of the safety protection sleeve on the needle head, and the needle head is sheathed and prevented from being exposed, so that the purpose of safety protection of the used needle head is achieved.
Although the sheath structure of the aforementioned prior injection and blood sampling needle can achieve the purpose of protecting the needle after use, the sheath structure still has its disadvantages, such as: the safety sheath is integrally connected to one side of the needle head seat, so that the needle head seat and the safety sheath need to be provided with a complex mold in the integral manufacture, the manufacture complexity and the cost of the safety sheath are improved, the safety sheath is not in accordance with the economic benefit, and if the safety sheath is arranged on the needle head seat in an adhesion mode, the safety sheath is easy to fall off, so that the prior art has a non-ideal design aiming at the integral (connection) manufacture of the safety sheath and the needle head seat. Moreover, the two sections of the elastic mechanism connected to the connecting mechanism (or the turnover mechanism) also have a supporting function, but the connecting acting force of the elastic mechanism is not strong, so that the jade can be broken at the upward turnover bending after the downward turnover operation of the connecting mechanism before use, or the two sections of the elastic mechanism connected to the connecting mechanism (the turnover mechanism) can be broken, which can cause the safety sheath to be incapable of being used normally; in addition, when the syringe or blood collection needle covered with the safety sheath after use is discarded in the subsequent collection, transportation and other processes, the two sections of the connecting mechanism (turnover mechanism) or the connecting section of the elastic mechanism and the connecting mechanism (turnover mechanism) may be broken by external impact, and the safety sheath may fall off, which may cause a potential danger in needle waste disposal and need to be improved. Therefore, how to improve the disadvantages of the safety sheath structure of the prior injector, blood collection needle, etc., is an important direction for the industry to solve and overcome.
In view of the disadvantages of the prior art and the fact that the structure of the safety sheath for syringes, blood collection needles, etc. is not ideal, the inventor of the present invention is expecting to develop a needle safety sheath structure with better stability, safety and economic benefits, so as to serve the public and promote the development of the industry, and thus the present invention is developed based on the multi-time conception.
