Description

本考案は低背圧の注射針不要な装置に関し、特に、医療器具に応用され、輸血や点滴を行うことができる低背圧の注射針不要な装置に関する。   The present invention relates to a low back pressure injection needle-free device, and more particularly to a low back pressure injection needle-free device that can be applied to medical instruments and can perform blood transfusion and infusion.

医療従事者が薬剤を注入する時に使用する薬剤添加チューブは、従来、図１に示すような、薬剤添加口ａ１１を具える中空チューブａ１である。前記薬剤添加口ａ１１は栓体ａ１２を有し、前記栓体ａ１２は軟性の物質である。医療従事者が薬剤を注入する時に、まず薬剤を注入装置２ａで抽出して吸入し、注入装置ａ２の注射針ａ２１を栓体ａ１２から薬剤添加チューブａ１内にまで差し込み、その後、注入装置ａ２のプッシュロッドａ２２を押せば、薬剤を薬剤添加チューブａ１内に注入することができる。   Conventionally, a drug addition tube used when a medical worker injects a drug is a hollow tube a1 having a drug addition port a11 as shown in FIG. The drug addition port a11 has a plug a12, and the plug a12 is a soft substance. When a medical worker injects a drug, the drug is first extracted and inhaled by the injection device 2a, the injection needle a21 of the injection device a2 is inserted from the plug a12 into the drug addition tube a1, and then the injection device a2 By pushing the push rod a22, the medicine can be injected into the medicine addition tube a1.

しかしながら、注射針ａ２１は鋭利な構造であるため、医療従事者が注入装置ａ２を使用する時、不注意により注射針ａ２１で刺して怪我をする可能性があり、もし注射針ａ２１が清潔でない場合は感染を引き起こすこともある。
また、注入装置ａ２の注射針ａ２１を使用して薬剤を直接人体の中に注入する場合、注入する速度が速すぎると患者に不快感を与え、しかも注入装置ａ２を抜く時に空気の回流により生じる圧力、（以下これを「背圧」という。）により患者に痛みを与えることになる。 However, since the injection needle a21 has a sharp structure, when a medical worker uses the injection device a2, the injection needle a21 may be inadvertently punctured with the injection needle a21, and the injection needle a21 is not clean.

In addition, when a medicine is directly injected into the human body using the injection needle a21 of the injection device a2, the patient is uncomfortable if the injection speed is too high, and is caused by the circulation of air when the injection device a2 is pulled out. The pressure (hereinafter referred to as “back pressure”) causes pain to the patient.

従って、注射針ａ２１を使わないで薬剤を添加できる薬剤添加チューブａ１を設計することができれば、医療従事者が感染する機会をなくし、使用上の安全性を高めることができ、しかも、使用後の注射針ａ２１を捨てる必要がなく、コストも削減できる。   Therefore, if the drug addition tube a1 that can add a drug without using the injection needle a21 can be designed, the medical staff can eliminate the chance of infection and increase the safety in use. It is not necessary to discard the injection needle a21, and the cost can be reduced.
