Abstract

The utility model relates to a hydrophilic super-lubricity coating urethral catheter which is characterized by comprising a connector and a catheter body. The catheter body is made by the aid of variable-strength reinforcing mesh weaving technique, reinforcing wires are added into a weaving layer, the surface of the catheter body is pretreated by the aid of prepared composite coupling agents, a grafting reaction is performed on the surface of the catheter body in a hydrophilic single thermo-cross-linking mode, the surface of the catheter body after the grafting reaction is dried or baked, so that the urethral catheter is provided with a hydrophilic super-lubricity coating, the surface of the catheter body is quite smooth, the urethral catheter is simple and convenient to operate in the operation process, tissue injury can be decreased, the probability of complications such as tissue bleeding and infection is greatly reduced, and the pain of a patient is relieved.

Description

亲水超滑涂层引尿管 Super hydrophilic catheter slip coat primer

所属技术领域 Those of skill

[0001] 本实用新型涉及医疗器械领域,特别涉及亲水超滑涂层引尿管。 [0001] The present invention relates to medical devices, and more particularly relates to a super-slippery hydrophilic coating primer catheter.

技术背景 technical background

[0002] 在医疗运用领域,当使用引尿管进入人体时由于普通管体表面润滑性不够,特别容易损伤人体而出现导管回血现,而这样必定会影响医疗效果,并可能增加并发症的发生概率;此外,未经处理的引尿管在使用过程中往往存在摩擦力大的问题,如果引尿管表面润滑性不够,还会增加操作难度,给患者带来痛苦。 [0002] In the medical use of the field, when using a catheter introduced into the human body due to the tube surface lubricity ordinary enough, are particularly vulnerable to damage the body and blood appeared catheter back now, and this will definitely affect health outcomes, and may increase the incidence of complications probability; in addition, there is often quoted without the catheter in the course of processing a large friction problem, if the lead catheter surface lubricity is not enough, it will also increase the difficulty of the operation, to patients with pain. 从而需要对表面进行润滑处理以减少病人痛苦及对病人的伤害,现有涂层一般使用甲基乙基酮作为溶剂,采用单独的UV交联方式,这对环境和造作者容易造成伤害,且成本较高。 Thus the need for surface lubrication treatment in order to reduce patient pain and injury to the patient, the existing coating is generally used as a solvent, methyl ethyl ketone, with a separate UV crosslinking means, it is easy to cause harm to the environment and made of, and higher cost.

实用新型内容 SUMMARY

[0003] 本实用新型为解决上述技术缺点,本实用新型采用以下技术方案:通过对管体表面用制备过的复合偶联剂进行预处理,再采用亲水性单体热交联方式在导管表面进行接枝反应,最后对接枝反应后的导管表面进行晾干、烘干制备而成。 [0003] The present invention is to solve the above drawbacks, the present invention employs the following: pre-treated by a composite pipe coupling of the surface treated with the preparation, then using hydrophilic monomer in the conduit thermally crosslinking means surface grafting reaction, and finally to the catheter surface grafting reactions carried out after drying, was prepared from drying. 使其具有一层亲水超滑涂层。 It has a hydrophilic coating over the slide. 所述的复合偶联剂是将硅烷偶联剂KH-550,T0-80表面活性剂和亲水有机氟溶解在乙醇溶剂中制备而成的。 Coupling said composite is prepared by dissolving in ethanol solvent, a silane coupling agent KH-550, T0-80 surfactant and a hydrophilic organic fluorine. 所述的亲水性单体可选用N-乙烯基吡咯烷酮(NVP)、聚乙烯吡咯烷酮(PVP)、聚乙二醇、聚环氧乙烷、聚乙烯醇等。 The hydrophilic monomer can be selected N- vinyl pyrrolidone (NVP), polyvinyl pyrrolidone (PVP), polyethylene glycol, polyethylene oxide, polyvinyl alcohol and the like.

[0004] 本实用新型解决了背景技术中存在的缺陷,减少了溶剂残留量。 [0004] The present invention address the deficiencies of the background art exist to reduce the residual solvents. 同时净化了操作环境,避免溶剂污染的可能,同时使引尿管达到优良的使用效果,达到先进医疗器械的要求。 Purify the operating environment, to avoid possible contamination of the solvent, while the catheter lead achieve good results, meet the requirements of advanced medical devices.
