Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] The core of the present invention is to provide an injection needle, which can be preloaded into an automatic injection device and ensure safe sterility. Another core of the present invention is to provide an automatic injection device including the above injection needle, which can realize one-button automatic injection on the basis of ensuring safety and sterility, and has low manufacturing cost.
[0035] Please refer to figure 1 and figure 2 , fi...

The invention discloses an injection needle. The injection needle comprises a needle base, a double-blade needle body arranged on the needle base, a needle protecting cap and a sealing membrane, wherein the needle protecting cap is connected with one end of the needle base, sleeves the exposed outer periphery of one end of the double-blade needle body, and is an elastic part; the sealing membraneis arranged at the other end of the needle base and used for sealing the double-blade needle body. The injection needle can be loaded into an automatic injection device in advance, safety and sterility are guaranteed, and when the injection needle is applied to the automatic injection device, one-key type automatic injection of the automatic injection device can be realized on the basis that the safety and sterility are guaranteed; the injection needle can adapt to most existing buckle type bottle package medicine in the market, a needle pre-encapsulating technology is not needed, the using limit of the medicine is reduced, and the producing and manufacturing cost for medical instrument combination and assembly is lowered. The invention further discloses the automatic injection device withthe injection needle. The automatic injection device comprises the injection needle, and can realize one-key type automatic injection on the basis that the safety and sterility are guaranteed, and the producing and manufacturing cost is low.
Description
technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, to an injection needle. In addition, the present invention also relates to an automatic injection device comprising the above-mentioned injection needle. Background technique [0002] With the increasing incidence of sudden diseases such as cardiovascular and cerebrovascular diseases, emergency injection devices that can realize one-button automatic injection function are particularly important. [0003] Injection devices in the prior art are usually aimed at the management of chronic diseases such as diabetes, including injection pens and injection needles. Due to the high safety and sterility requirements for self-management injection needles, usually, injection pens and matching The injection needles used are purchased and sold separately, and then assembled and replaced when used. However, it takes a certain amount of time to temporarily assemble the injec...
