Description
技术领域technical field
本发明涉及留置针，属于医疗器械技术领域。The invention relates to an indwelling needle and belongs to the technical field of medical instruments.
背景技术Background technique
输液几乎可将所有药液通过血管输入人体，实现治疗和预防疾病的目的，临床中，为避免多次穿刺造成血管的损伤及减少病人的痛苦，也为减轻医护人员的操作强度，已普遍使用了留置针（管）技术。现在临床使用的留置针一般包括留置针座、留置软管、延长管、延长管座、装置于延长管上的止液夹，这种结构组成的留置针中其延长管都是采用单腔导管，在输液暂停过程中，通过操作延长管上的止液夹使延长管座与留置针座和留置软管之间形成隔断，避免空气和异物通过留置软管进入到病人血液中。但由于人体静脉压的作用，在暂停输液的过程中，血液会逆流而进入到留置软管及留置针座中，甚至于进入到延长管的止液夹以下部分中，时间一长就会在这些部位中形成血栓，需要使用肝素钠对留置针管进行抗凝封闭，以达到在留置针管中不产生栓塞的目的，而在输液和对留置针管进行抗凝封闭的过程中均需要使用针刺连接，这样无形中增加 了护士的工作量和劳动强度，同时也存在医护人员被针刺误伤的危险性，针对上述问题的存在，中国专利CN104043162A公开了一种名称为防血栓静脉留置针及其防血栓的方法的专利申请，该防血栓静脉留置针包括留置针座、留置软管、穿刺针和延长管，留置针座的侧壁上设有药液输入口，留置针座的一端设有药液输出口，留置软管与留置针座的药液输出口连接，穿刺针的针尖从留置针座的另一端穿入留置针座内，经药液输出口从留置软管穿出，还包括引流软管、引流条和夹具，所述引流软管的一端与药液输入口连接，另一端与延长管的一端连接，引流条设在引流软管中，夹具夹在引流软管上。但该专利申请存在有以下缺陷：①引流管和引流条的设置，造成工艺复杂，制造成本高；②引流管和引流条的存在影响输液过程中药液的滴注速度和顺畅性，甚至于造成药液滴注通道的阻塞，特别地亲水材料制成的引流线存在有纤维脱落并溶解于针座腔体和留置软管中的可能，造成纤维异物随液体进入人体血液中，严重危害人体健康。Infusion can inject almost all medicinal liquid into the human body through blood vessels to achieve the purpose of treating and preventing diseases. In clinical practice, it has been widely used in order to avoid the damage of blood vessels caused by multiple punctures and reduce the pain of patients, as well as to reduce the operating intensity of medical staff. Indwelling needle (tube) technology. The clinically used indwelling needles generally include an indwelling needle base, an indwelling hose, an extension tube, an extension tube base, and a liquid stop clip installed on the extension tube. The extension tubes of the indwelling needles with this structure are all single-lumen catheters. , During the suspending process of infusion, by operating the liquid stop clip on the extension tube, the extension tube base, the indwelling needle base and the indwelling hose are separated to prevent air and foreign matter from entering the patient's blood through the indwelling hose. However, due to the venous pressure of the human body, during the suspension of the infusion, the blood will flow back into the indwelling hose and the indwelling needle seat, and even enter the part below the stop clamp of the extension tube. When thrombus forms in these parts, it is necessary to use heparin sodium to anticoagulate and seal the indwelling needle to achieve the purpose of not generating embolism in the indwelling needle, and needle connection is required in the process of infusion and anticoagulant sealing of the indwelling needle In this way, the workload and labor intensity of nurses are virtually increased, and there is also the risk of accidental injury of medical personnel by needle sticks. In view of the existence of the above problems, Chinese patent CN104043162A discloses an antithrombotic venous indwelling needle and its antithrombotic indwelling needle. The patent application for the method of thrombosis, the anti-thrombotic venous indwelling needle includes an indwelling needle base, an indwelling hose, a puncture needle and an extension tube. Liquid output port, the indwelling hose is connected with the liquid medicine output port of the indwelling needle base, the needle tip of the puncture needle penetrates into the indwelling needle base from the other end of the indwelling needle base, and passes through the indwelling hose through the liquid medicine output port, and includes Drainage hose, drainage strip and clamp, one end of the drainage hose is connected to the liquid medicine input port, the other end is connected to one end of the extension tube, the drainage strip is arranged in the drainage hose, and the clamp is clamped on the drainage hose. But this patent application has the following defects: 1. the arrangement of the drainage tube and the drainage strip causes complex process and high manufacturing cost; Cause the blockage of the infusion channel of the drug solution, especially the drainage line made of hydrophilic material may have fibers falling off and dissolving in the cavity of the needle seat and the indwelling hose, causing the fiber foreign matter to enter the blood of the human body with the liquid, seriously endangering the human health.
