Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a needleless injection system.
Background
The traditional syringe is an injection mode for injecting medicines into a human body through a stainless steel needle, and the injection mode easily causes subcutaneous and muscle tissue damage, produces cysts and even infection, is not only painful and uncomfortable for patients, but also causes fear for most patients (especially infants). The accidental breakage of the needle is easy to happen in the injection process, and a large amount of medicine injected through the metal needle is concentrated at one point, so that the medicine is formed into a lump at the injection part and is not easy to absorb.
160 hundred million needles are treated every year all over the world, and sharp metal needles are combined with various components such as rubber pistons, plastic materials and the like, so that the environment pollution and the resource waste are caused to human beings.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a needleless injection system to solve the medicament that traditional syringe injected into and be difficult to absorb, and make the painful strong problem of feeling of patient.
To solve the above technical problem, the present invention provides a needle-free injection system, comprising:
the air source input end of the injection gun is communicated with the air pressure device through a hose;
the injection end connector of the injection gun is detachably provided with an injection head.
Optionally, the needleless injection system further comprises a pressure regulating device installed on the air pressure device, and the air source input end is communicated with the pressure regulating device through the hose.
Optionally, the injection end of the injection gun comprises a barrel, a pinhole bracket, a hole nut and a needle joint nut; wherein,
the pinhole bracket is positioned in the gun barrel and is fixed through a hole nut; the pin joint nut is rotationally fixed on the hole nut.
Optionally, the side of the barrel is provided with an opening for connecting with an injection cylinder.
Optionally, the injection gun is further provided with a dose adjustment device for adjusting the injected dose.
Optionally, the pneumatic device comprises a gas cylinder and an air compressor.
The needleless injection system provided by the utility model comprises an injection gun, wherein the air source input end of the injection gun is communicated with an air pressure device through a hose; the injection end connector of the injection gun is detachably provided with an injection head. The utility model provides a needleless injection system uses compressed gas as power, makes the medicament accelerate to 200 types of plus-pressure drugs speed 300 meters per second to form an extremely tiny liquid flow, pierce through the skin top layer rapidly, spread in the soft tissue, increase the absorption area, improve the absorption effect, needleless injection avoids the syringe needle fracture in the human body, and the pain that just significantly reduces.
Drawings
Fig. 1 is a schematic view of a needleless injection system provided by the present invention;
fig. 2 is a schematic view of the exploded structure of the injection end of the gun.
Detailed Description
The present invention provides a needleless injection system, which is described in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
Example one
The utility model provides a needleless injection system, which comprises an injection gun 1, wherein an air source input end 11 of the injection gun 1 is communicated with an air pressure device 3 through a hose 2; an injection head 13 is detachably arranged on the joint of the injection end 12 of the injection gun 1. The air pressure device 3 comprises an air bottle and an air compressor.
Further, the needleless injection system further comprises a pressure regulating device 4 installed on the air pressure device 3, and the air source input end 11 is communicated with the pressure regulating device 4 through the hose 2. The pressure regulating device 4 is used for regulating the air pressure of the air pressure device 3.
Specifically, please refer to fig. 2, which is a schematic diagram of an exploded structure of the injection end 12 of the injection gun 1. The injection end 12 of the injection gun 1 comprises a barrel 121, a needle hole bracket 122, a hole nut 123 and a needle joint nut 124; wherein the pinhole bracket 122 is located in the barrel 121 and is fixed by a hole nut 123; the pin connector nut 124 is rotatably fixed to the hole nut 123. Specifically, the side of the barrel 121 is provided with an opening for connecting an injection cartridge. The gun 1 is further provided with a dose setting device 14 for setting the dose to be injected.
The needleless injection system provided by the utility model takes compressed gas as power, so that the medicine is accelerated to the speed of 200 plus 300 meters per second, and an extremely tiny liquid flow is formed, which rapidly penetrates through the surface layer of the skin and is diffused in soft tissues, thereby increasing the absorption area and improving the absorption effect; the pressure can be controlled by the pressure regulating device, the injection pressure can be changed at will, and the medicament can be accurately reached to a target part. Needleless injection avoids needle breakage in the body and greatly reduces pain.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
