Injection protection device for intramuscular injection

Abstract

The invention belongs to the technical field of safety accessories of injectors, and particularly relates to an injection protection device for an intramuscular injection. The injection protection device achieves the purpose of simple, efficient and accurate intramuscular injection operation by arranging a limiting ring for insertion, an inner tube unit, a spring unit and a radial clamping plate unit on a protective outer tube. The injection protection device has the advantages that the structure of the protection device is reasonable and effective, the insertion action of the injector is not too deep, too fast or inclined easily during intramuscular injection, the action of firstly clamping an inner tube to the bottom and then inserting the injector into the muscle is simple and efficient, the injector has a clamping anti-return effect after a needle is inserted in place, a needle cylinder of the injector does not need to be held and fixed, the protection device is suitable for injectors with needle cylinders with different thicknesses, and the whole intramuscular injection operation is more accurate, sanitary and convenient.

Description

technical field [0001] 本发明属于注射器安全配件技术领域,尤其涉及一种肌肉注射器用注射防护装置。 Background technique [0002] 注射防护装置,指的是配合注射器使用,主要用于提升注射操作安全性和洁净度的辅助配件,其结构主要包括防护外管和管内限位块,其中防护外管保证遮盖保护和引导针头插入的功能,管内限位块则用于限制针头的最大插入深度,避免发生针头插入过深的问题。 [0003] 但是另一方面,现有的注射防护装置在用于肌肉注射时,则又存在以下两个问题:第一,整个防护装置过长、管内限位块限制针头的最大插入深度不足,不能满足相较于皮肤注射操作更深的肌肉注射的要求;第二,整个注射防护效果不到位,辅助注射使用仍然存在使用不够方便、不够高效以及对操作精度要求相对较高的问题。 [0004] 所以综上所述,市场上急需一种适用于肌肉注射,且可以让注射操作更加简单、精准、舒适、卫生以及安全的注射防护装置。 [0005] 专利公告号为CN211751547U,公告日为2020.10.27的中国实用新型专利公开了一种适用于注射器的安全防护组件,包括固定座和针管护罩,所述针管护罩与固定座设有活动卡接机构,针管护罩的前部与固定座的前部之间设有铰接回弹机构,针管护罩与固定座解除卡接后铰接回弹机构的回弹力使针管护罩围绕铰接处翻转并将注射器针管罩设其中;在固定座的上设有将固定座安装在注射器上的安装机构。 [0006] 但是该实用新型专利中的注射器安全防护组件,存在配合注射器使用时整个注射操作仍然难度较大、准度不方便把控的问题。 Contents of the invention [0007] 本发明提供一种肌肉注射器用注射防护装置,其能通过在防护外管上设置插入用限位环、内管单元、弹簧单元以及径向卡合板单元的方式,达到肌肉注射操作简单、高效以及精准的目的。 [0008] 本发明解决上述问题采用的技术方案是:一种肌肉注射器用注射防护装置,包括防护外管,以及设置在所述防护外管内环面上的插入用限位环,还包括设置在所述防护外管内并用于插入安装注射器的内管单元,设置在所述插入用限位环上表面上并用于对所述内管单元的向下插入动作进行缓冲保护的弹簧单元,以及设置在所述防护外管外环面上端位置处并在所述内管单元上插入注...

AI Technical Summary

Problems solved by technology

[0003] But on the other hand, when the existing injection protection device is used for intramuscular injection, there are the following two problems: first, the entire protection device is too long, and the limit block in the tube limits the maximum insertion depth of the needle. Compared with the skin injection operation, the requirement for intramuscular injection is deeper; second, the overall injection protection effect is not in place, and the use of auxiliary injection still has the problems of inconvenient use, insufficient efficiency, and relatively high requirements for operation accuracy

[0006] However, the syringe safety protection component in this utility model patent has the problem that the entire injection operation is still difficult when used with a syringe, and the accuracy is inconvenient to control.
