Problems solved by technology
[0002] Among the traditional syringes, one is a glass syringe that is repeatedly sterilized, and the other is a plastic syringe that is disposable and discarded. When using these two types of syringes, the needle needs to be inserted into the medicine bottle containing the liquid medicine first. In the process, inject the patient after inhaling the liquid medicine, the syringe and the medicine bottle are set separately, the work efficiency is low and the operation is cumbersome during injection
In order to overcome the above-mentioned defects, various syringes combining syringes and medicine bottles have also appeared at present, such as the utility model patent of patent No. CN98249286.3, which discloses a dental anesthetic syringe used in dentistry. Bottles and needles are disposable, but syringes are reusable, so this kind of syringe cannot ensure the self-destructability of the syringe itself after the injection is completed, fundamentally prevents the phenomenon of repeated use, and cannot guarantee personal health
At the same time, after the existing syringes are used up, the collectors of the syringes will accidentally be stabbed by the exposed syringe needles when collecting the discarded syringes, which is very poor in safety.

Embodiment Construction
[0018] As shown in Figure 1, the present invention comprises a hollow overcoat 1, an end of the overcoat 1 inserted and fixed therein, a handguard 2 arranged in the same hole as the overcoat 1, a medicine bottle 4 positioned in the inner cavity of the overcoat 1,
[0019] A fixed seat 5 is set in the inner cavity of the jacket 1, and the fixed seat 5 slides left and right along the inner cavity of the jacket 1 between the two ports of the jacket. 4. The bayonet of the head is provided with a beveled protrusion 10 on the outside of the bayonet. There is a protrusion 11 in the inner cavity of one end of the jacket 1, which restricts the fixing seat 5 from sliding out of the port of the jacket 1. The other end of the jacket 1 There is a protrusion 12 with a slope in the inner cavity of the inner cavity, and the protrusion 12 cooperates with the protrusion 10 of the fixing seat 5, and restricts the fixing seat 5 from returning to the inner cavity of the jacket 1, and the outer side...

A self-destroying high-safety expendable injector with built-in liquid medicine bottle for preventing cross infection of diseases is composed of hollow external sleeve, hand protector fixed to one end of said external sleeve, liquid medicine bottle in the inner cavity of external sleeve, fixer sliding in external sleeve, needle installed to said fixer, and push rod inserted in the back plug of liquid medicine bottle.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to a disposable self-destruction safety syringe with a built-in medicine bottle and ensuring that the syringe cannot be reused after injection. Background technique [0002] Among the traditional syringes, one is a glass syringe that is repeatedly sterilized, and the other is a plastic syringe that is disposable and discarded. When using these two types of syringes, the needle needs to be inserted into the medicine bottle containing the liquid medicine first. In the process, the patient is injected after inhaling the liquid medicine. The syringe and the medicine bottle are set separately, and the work efficiency is low and the operation is cumbersome during injection. In order to overcome the above-mentioned defects, various syringes combining syringes and medicine bottles have also appeared at present, such as the utility model patent of patent No. CN98249286.3, which discl...
