Hand-held automatic hypodermic fixator

Abstract

The invention provides a hand-held automatic hypodermic fixator comprising an outer sleeve, an inner sleeve and a propeller; the side face of the lower segment of the outer sleeve is provided with an opening, so an injector can be placed in; the opening of the outer sleeve is provided with an openable protector cover; the lower segment of the outer sleeve is provided with an adjusting fixing mechanism, and provided with scales; the top of the lower segment of the outer sleeve is also provided with a needle hole; the upper segment of the outer sleeve is provided with inner thread, the inner sleeve is provided with outer thread, and the inner sleeve can slide up and down in the outer sleeve; the propeller is arranged in the inner sleeve, and provided with a guide rail in the inner sleeve length direction; the guide rail is nested in a guide slot on the side wall of the inner sleeve; the propeller can move up and down relative to the inner sleeve; the propeller is driven by an electric control drive mechanism; the electric control drive mechanism is arranged on the inner sleeve, can adjust the propulsion stroke length of the propeller, and can adjust the propulsion time of the propeller. The hand-held automatic hypodermic fixator can stabilize the injector, so the injection can be automatically done, thus providing better injection effect for patients.

Description

technical field [0001] The invention relates to an injection aid, in particular to a hypodermic injection fixator. Background technique [0002] Subcutaneous injection is a commonly used treatment method in the medical industry at present, but due to the different drugs injected under the skin, the length and thickness of the needles are different, and the length of the needle handle is also different, and some subcutaneous injections such as low molecular weight heparin require injection stability. Relatively high, when nurses usually operate, they need to fix the skin with one hand, and perform multiple operations such as needle removal, puncture, injection, and needle withdrawal with the other hand, which may easily cause the nurse's hand to move around when injecting, and press when injecting The injection handle will inevitably affect the effect of puncture. Moreover, different nurses have different injection techniques, which will also bring different puncture pains t...
