Description
技术领域 technical field
本实用新型涉及医疗器械，具体涉及一种压力注射器械。The utility model relates to a medical device, in particular to a pressure injection device.
背景技术 Background technique
注射器械，是一种临床中常用的治疗器械，适用于药物注射治疗、局部麻醉给药、病变部位直接注入治疗等。但在皮肤肌肉较丰满且压力较高部位注射时，常常由于注射筒内反馈压力过高，导致注射针与针筒脱落、药物外泄、甚至因为注射针与针筒脱落瞬间滑动误刺入正常组织，引起损伤，后果严重。Injection equipment is a commonly used clinical treatment equipment, which is suitable for drug injection treatment, local anesthesia administration, direct injection treatment of lesion parts, etc. However, when injecting in areas with plump skin and muscles and high pressure, the injection needle and the syringe often fall off due to the high feedback pressure in the injection barrel, the drug leaks out, and even the injection needle and the syringe slide off instantly and slip into the normal area by mistake. tissue, causing damage with serious consequences.
注射器械因压力导致注射针与针筒脱落，通常发生在注射针与针筒连接部位，因连接部位为光滑面接触，不能承受针筒内部压力。所以在对压力较大部位注射时，施术者常常因压力过大，导致注射针与针筒脱落、药液外泄，药液对施术者和患者都可造成损伤。同时因为担心压力注射针与针筒脱落，施术者不敢过度施压推注药物，最终引发药物不能注入治疗部位，影响治疗。为此开发一种压力部位注射治疗器械成为急需解决的临床问题。The injection needle and the syringe of the injection device fall off due to pressure, which usually occurs at the connection part of the injection needle and the syringe. Because the connection part is in contact with a smooth surface, it cannot withstand the internal pressure of the syringe. Therefore, when injecting to a part with high pressure, the operator often causes the injection needle and the syringe to fall off due to excessive pressure, and the medicinal liquid leaks out, and the medicinal liquid can cause damage to the operator and the patient. At the same time, because the pressure injection needle and the syringe are worried about falling off, the operator dare not apply excessive pressure to inject the drug, which will eventually cause the drug to be unable to inject the treatment site, affecting the treatment. For this reason, developing a pressure site injection therapy device has become an urgent clinical problem to be solved.
目前国内仍采用常规注射针与针筒连接，即连接部位为光滑面接触，压力部位操作时为了防止注射针与针筒脱落，施术者不敢过度施压推注药物，药物不能注入治疗部位，达不到治疗要求。如果因压力过大，导致注射针与针筒脱落、药液外泄，药液对施术者和患者都可造成损伤，后果严重。At present, conventional injection needles and syringes are still connected in China, that is, the connection part is in contact with a smooth surface. In order to prevent the injection needle and syringe from falling off during the operation of the pressure part, the operator dare not apply excessive pressure to push the drug, and the drug cannot be injected into the treatment area. , can not meet the treatment requirements. If the injection needle and syringe fall off due to excessive pressure and the liquid medicine leaks out, the liquid medicine can cause damage to both the operator and the patient, with serious consequences.
