Problems solved by technology

[0004] The more successful needle-free syringes on the market mostly use strong springs as the power source of the syringes, which are small in size, light in weight, and easy to carry. However, after each injection is completed, a special reset device is required to recompress the spring to store energy and operate The process is too cumbersome

Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the pneumatic needle-free injector of the present invention will be further described in detail through the following examples and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] It should be noted that when an element is said to be "fixed" to another element, it may be directly fixed to the other element or may be fixed to the other element through an intermediate element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or connected to the other element through intervening elements. In addition, unless otherwise specified, the descriptions of the terms "first" and "second" in the specification are only used to distinguish each component, elem...

Abstract

The invention discloses a fixed-dosage single-injection pneumatic needleless injector. The fixed-dosage single-injection pneumatic needleless injector comprises a power supply device, a power unit, a shooting type cavity, a gun tube and a disposable ampoule bottle, wherein the power supply device comprises an air source, a reversing valve and air delivering hoses; a pressure regulating device and a pressure gage are arranged on an air outlet pipeline of the air source; an air outlet of the air source is connected with the two air delivering hoses through the reversing valve; and the air delivering hoses are connected with the power unit. The air discharge pressure of the air source can be adjusted, and injection of different parts and different injection depths is realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a fixed-dose single-injection pneumatic needle-free injector. Background technique [0002] Needle-free syringes do not need to use needles when injecting drugs, and use the principle of high-pressure jets to make the liquid medicine form a finer fluid, which instantly penetrates the skin and reaches the subcutaneous area. [0003] Needle-free injection can not see the needle, the psychological resistance to treatment will be minimized, and the compliance of treatment will be improved, especially for children with diabetes. Needle-free injection can bring many benefits to diabetic patients, such as greatly reducing the pain caused by needle-based syringes, and avoiding the formation of induration at the injection site after repeated injections. [0004] The more successful needle-free syringes on the market mostly use strong springs as the power source of the syringes, which are s...
