[0002] A syringe is a common medical appliance, mainly used to extract or inject gas or liquid with a needle. The syringe can also be used for medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum, while the currently used medical syringes require When used with a needle, the patient needs to suffer pain during use, and it has a certain cross-infection effect. At the same time, the drug solution usually accumulates in the patient's body after injection, and the absorption rate is low

The invention discloses a medical needleless injector. The medical needleless injector comprises an outer pipe, a push disk, a medicine storage bag, a bottom table and a window, wherein a top groove is formed in the top end of the outer pipe, and one side of the top groove is of an opening structure; the top end of the push disk is of an arc-shaped structure, the push disk is arranged in the top groove, the lower part of the top groove is connected with one end of a first push rod, and the other end of the first push rod penetrates through the bottom of the top groove and extends into the outer pipe to be connected with one end of the medicine storage bag; a spring, a second push rod and fixed connecting pieces are arranged, the fixed connecting pieces are a plurality of plastic sheets distributed in an equal spacing manner, the spring can be guaranteed to always maintain in a compressed state and stored in the injector, and when the injector needs to be used, the push disk is pressed,and the first push rod drives the second push rod to break the fixed connecting pieces; and under the springback effect of the spring, the medicine storage bag can be extruded to complete liquid medicine injection, the pressing process and the pressing distance are greatly shortened through the design, and the use convenience is improved.
Description
technical field [0001] The invention relates to the related technical field of medical injectors, in particular to a medical needle-free injector. Background technique [0002] A syringe is a common medical appliance, mainly used to extract or inject gas or liquid with a needle. The syringe can also be used for medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum, while the currently used medical syringes require When used with a needle, the patient needs to suffer pain during use, and it has a certain cross-infection effect. At the same time, the liquid medicine usually accumulates in the patient's body after injection, and the absorption rate is low. [0003] For this reason, a kind of medical needle-free injector is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a medical needle-free injector, which realizes rapid injection without using with a needle, an...
