A negative pressure adsorption hypodermic injection device relates to a device for subcutaneously injecting insulin and other medicaments. It consists of an adsorption device, an air compression device, a quick deflation device, and an injection syringe. Among them, the adsorber 1 and the air compressor 3 are connected by the air pipe 2. The air in the adsorber 1 can be quickly extracted through the air compressor 3, so that a negative pressure is formed in the adsorber 1 and the skin shrinks and bulges. Adjust the puff height of the skin. The injection syringe 4 is sealed and connected to the absorber 1 through the needle step, and when the skin shrinks and bulges, the needle is automatically pierced into the skin, and then the medicament can be injected. The quick deflation device consists of a rubber plug 5. When the rubber plug 5 is pulled out, the air pressure in the absorber 1 returns to atmospheric pressure, the skin relaxes and becomes smooth, and the needle is automatically pulled out from the skin. For subcutaneous injection, the present invention has the characteristics of easy skin tightening, rapid needle injection, convenient injection, convenient use, wide application range, etc., and solves the problem that it is difficult for the elderly and thin people to inject subcutaneous injections such as insulin.
Description
技术领域technical field
本发明涉及皮下注射装置，具体涉及一种利用负压吸附进行皮下注射的皮下注射装置。The invention relates to a subcutaneous injection device, in particular to a subcutaneous injection device for subcutaneous injection using negative pressure adsorption.
技术背景technical background
注射是借助注射器一类的医疗器械将液体或气体注入人体，以达到诊断、治疗或预防疾病的目的。目前的注射途径有以下几种：皮内注射、皮下注射、肌肉注射、静脉注射、动脉注射等。对于于疫苗和菌苗的预防接种、局部麻醉及如胰岛素等某些药物的注射，必须采用将药剂注入皮下组织的皮下注射方法。常用皮下注射部位有上臂外侧、腹部、大腿外侧、臀部等部位，不同部位有不同效果。目前，皮下注射患者都是利用一只手直接挤压注射部位皮肤使脂肪层收缩，另一只手用注射器将药剂注入皮下组织的注射方法。这种注射方法对于不同人群，会有一定的困难，如老人身体不灵活而难以自我注射，偏瘦者由于脂肪过少而难以将药剂注入皮下组织等。此外，对于某些患者，如糖尿病者，需要经常注射胰岛素等药剂，而由于现有这种注射技术的局限性，他们只能在身体正面易于注射部位如腹部进行注射，如此长期在同一部位会造成局部皮下脂肪组织萎缩，形成难看的橘皮样凹陷及局部皮肤硬化。因此，一种新的能将注射部位皮肤收缩鼓起的注射装置成为当前皮下注射的迫切需求。Injection is the injection of liquid or gas into the human body with the aid of medical devices such as syringes for the purpose of diagnosing, treating or preventing diseases. The current injection routes include the following: intradermal injection, subcutaneous injection, intramuscular injection, intravenous injection, arterial injection, etc. For the vaccination of vaccines and bacterins, local anesthesia, and the injection of certain drugs such as insulin, it is necessary to use the subcutaneous injection method of injecting the drug into the subcutaneous tissue. Commonly used subcutaneous injection sites include outer upper arm, abdomen, outer thigh, buttocks, etc. Different parts have different effects. At present, subcutaneous injection patients all use one hand to directly squeeze the skin of the injection site to shrink the fat layer, and the other hand uses a syringe to inject the drug into the subcutaneous tissue. This injection method will have certain difficulties for different groups of people, such as the elderly are not flexible enough to self-inject, and the underweight people have difficulty injecting the drug into the subcutaneous tissue due to too little fat. In addition, some patients, such as diabetics, need frequent injections of insulin and other medicaments, and due to the limitations of the existing injection technology, they can only inject at the front of the body where it is easy to inject, such as the abdomen. Cause local subcutaneous adipose tissue atrophy, form unsightly orange peel-like depressions and local skin hardening. Therefore, a new injection device that can shrink and bulge the skin at the injection site has become an urgent need for current subcutaneous injection.
发明内容Contents of the invention
本发明目的是提供一种用于皮下组织注射的注射装置。本发明由一个负压吸附装置，一个空气压缩装置，一个快速泄气装置，和一个给药模块组成。具体有易于将注射部位皮肤收缩鼓起，实现自动快速扎针，方便注射并有效避免断针现象，适用面广等特点。本发明中负压舱1和空气压缩器3由气管2连接，通过空气压缩器3可迅速抽取负压舱1内的空气，使负压舱1内形成负压进而使皮肤收缩鼓起，可通过空气压缩器3调节皮肤的鼓起高度。给药模块4通过针头6的台阶和负压舱1密封连接，当皮肤收缩鼓起时针头自动扎入皮肤中，然后即可进行药剂注射。快速泄气装置由气阀5构成，当调节气阀5时，负压舱1内气压恢复为大气压强，皮肤舒张恢复平整，针头自动从皮肤中拔出。The object of the present invention is to provide an injection device for subcutaneous tissue injection. The invention consists of a negative pressure adsorption device, an air compression device, a quick deflation device, and a drug delivery module. Specifically, it is easy to shrink and bulge the skin at the injection site, realize automatic and rapid needle insertion, facilitate injection and effectively avoid broken needles, and have a wide range of applications. In the present invention, the

具体实施方法Specific implementation method
本发明的具体的实施方式是：先往给药模块4的药剂室内注好药剂，将给药模块4与负压舱1连接旋紧，将气阀5关紧；将空气压缩器3用气管2与负压舱1密封连接，空气压缩器3可由手动真空枪构成，亦可用小气泵实现自动压缩气体。将负压舱1平置于需注射皮肤处(如臀部)，手动挤压真空枪3(或启动气泵)抽走负压舱1内空气，使皮肤迅速收缩鼓起，此过程中由于皮肤鼓起，针头6自动扎入皮肤中使患者不感到疼痛；缓慢将药剂注入皮肤内，注射完后调节气阀5使负压舱1内压强达到大气压进而皮肤舒张平整，此过程中针头6自动从皮肤中拔出。此装置便于老年人及偏瘦者快速找到扎针口，不必在扎针时捏压皮肤，造成皮下脂肪组织萎缩，形成难看的橘皮样凹陷及局部皮肤硬化，此外由于注射装置固定吸附在注射处，有效避免了断针的危险。更适于糖尿病患者随时随地自我注射胰岛素治疗。The specific embodiment of the present invention is: first go to the medicament chamber of the
