Abstract

The invention discloses a detachable automatic suction injector which comprises a needle head, a needle tube and a piston rod, wherein the needle tube is provided with a baffle ring; the piston rod is provided with a pressing shank; the baffle ring encircles the needle tube by a round; the width of the baffle ring extending to the surround is consistent; the pressing shank is of a circular shape around the piston rod serving as a circle center; an air bag is arranged between the pressing shank and the baffle ring; two ends of the air bag are respectively provided with an upper end connection device and a lower end connection device; the upper end connection device is detachably connected with the pressing shank; the lower end connection device is detachably connected with the needle tube; an inflating nozzle and a deflating nozzle which are used for inflating and deflating the air bag are arranged on the surface of the air bag. By inflation on the air bag, the piston rod can be pushed to move, so that the needle head can suck liquid; automatic control is realized; the upper end connection device, the lower end connection device and the air bag can be detached from the injector and also assembled on the injector, so that circulating utilization is realized, and the utilization rate of resources is increased.

Description

technical field [0001] The invention relates to a detachable automatic suction syringe, which belongs to the field of medical equipment. Background technique [0002] A syringe is a common medical appliance. The syringe is composed of a needle barrel with a small hole at the front end and a matching piston rod. Syringes are used to inject or withdraw small amounts of liquids into or from otherwise inaccessible areas. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. The process of withdrawing or injecting gas or liquid with a syringe and needle is called injection. [0003] At the same time, the syringe also has a suction function. The most commonly used in medical practice is to use the syringe to draw blood for the diagnosis of diseases. In the preparation of micro-dosage, use the syringe to suck the liquid medicine to realize the transf...
