Embodiment 1

[0019] The present invention provides a low-pressure needle-free injector, which includes an injection gun 1, the air source input end 11 of the injection gun 1 communicates with the air pressure device 3 through a hose 2; the injection end 12 of the injection gun 1 is detachable on the joint The injection head 13 is installed on the ground. The air pressure device 3 includes a gas cylinder and an air compressor.

[0020] Further, the low-pressure needle-free injector also includes a pressure regulating device 4 installed on the air pressure device 3 , and the air source input end 11 communicates with the pressure regulating device 4 through the hose 2 . The pressure regulating device 4 is used to adjust the air pressure of the air pressure device 3 .

[0021] Specifically, see figure 2 , is a schematic diagram of the exploded structure of the injection end 12 of the injection gun 1 . The injection end 12 of the injection gun 1 includes a gun barrel 121, a needle hole brac...

Abstract

The invention discloses a low-pressure needleless injection syringe, and belongs to the field of medical appliances. The low-pressure needleless injection syringe includes an injection gun, the air-source input end of the injection gun is communicated with an air pressure device through a hose, and a connector of the injection end of the injection gun is detachably provided with an injection head.The provided low-pressure needleless injection syringe uses compression air as power, speed of an medical agent is increased to 200-300 meters per second, an extremely small liquid flow is formed, penetrates through the skin surface rapidly and diffuses in soft tissue, the absorption area is increased, the absorption effect is improved, needleless injection can prevent syringe needles from beingbroken in the human body, and the pain is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a low-pressure needle-free injector. Background technique [0002] The traditional syringe is an injection method that injects medicine into the human body through a stainless steel needle. This injection method can easily cause subcutaneous and muscle tissue damage, cysts, and even infection. Not only the pain is strong, the patient is uncomfortable, but most patients (especially infants and young children) have a sense of fear. Accidental breakage of the needle is prone to occur during the injection process, and a large amount of medicine injected through the metal needle is concentrated at one point, and the medicine forms a lump at the injection site, which is not conducive to absorption. [0003] The whole world has to process 16 billion needles every year, and there are sharp metal needles, rubber pistons, plastic materials and other components together, which c...
