Description

一种亲水导尿管的润湿组件 Wetting of a hydrophilic urinary catheter assembly

技术领域 FIELD

[0001] 本发明涉及一种医用器具,尤其涉及一种亲水导尿管的润湿组件。 [0001] The present invention relates to a medical appliance, in particular, relates to the wettability of a hydrophilic urinary catheter assembly.

背景技术 Background technique

[0002] 在泌尿系统狭窄或损伤以及瘫痪等病人中,广泛采用间歇式自行插入导管进行导尿,使得病人日常生活和工作能够正常进行。 [0002] In the stenosis or injury, and urinary system paralysis patients, extensive use of intermittent self catheterization insertion catheter, such that the patient daily life and work can be performed properly. 间歇式自行插入用的导尿管通常在其插入段表面都需要涂上润滑物质,以实现导管插入段表面润滑和较低的摩擦系数,提高插入尿道过程中的舒适性。 Intermittent self-insertion catheter insertion section thereof generally require a surface coated with lubricant, in order to achieve the surface lubricity and low coefficient of friction of the catheter insertion section, improve comfort during insertion into the urethra. 目前市面上存在两种不同方式来实现导尿管插入部分的表面润滑。 Currently on the market there are two different ways to achieve lubricated catheter into the surface portion.

[0003] 其一:在导尿管插入段表面涂布润滑剂,润滑剂与导管表面以物理粘附形式附着(如凡士林、硅油),在普通状态下一直保持表面润滑效果。 [0003] One: the insertion section in the catheter surface coating lubricant, with the catheter attached to the surface (e.g., petrolatum, silicone oil) in the form of a physical adhesion, surface lubrication remains in normal state. 但是相对于亲水涂层技术而言,这种采用润滑剂涂布方式进行表面润滑的方法,需要使用的润滑剂量较大,同时涂布不易做到均匀,导管插入和拔出尿道过程中造成大量润滑剂残留在尿道内,引起不适;同时普通涂布润滑剂的方法无法比亲水涂层润滑技术达到更低的表面摩擦系数。 However, with respect to the hydrophilic coating technology, this embodiment uses a lubricant coating the surface lubricating method, the need to use a larger amount of lubricant, not easy to do while uniformly coated catheter during insertion and removal of the urethra caused by large amount of lubricant remaining in the urethra, causing discomfort; ordinary method simultaneously applying a lubricant to reach the surface friction coefficient not lower than the hydrophilic coating lubrication technology.

[0004] 其二:在导尿管插入段表面涂覆亲水涂层材料,该亲水涂层材料与导尿管表面以较牢固的化学键相连接,涂层在接触到润湿液后较短的时间内(数秒钟至数十秒钟)能表现出较强的润滑效果,极大地减小了导尿管的表面摩擦系数。 [0004] Second: the hydrophilic surface coating material in the coating section of the catheter is inserted, the hydrophilic catheter surface coating material at a relatively strong chemical bond is connected to the coating after exposure to the wetting fluid than within a short time (several seconds to tens of seconds) can show strong lubricating effect, greatly reduces the coefficient of friction of the surface of the catheter. 对于亲水润滑涂层的润湿,市面上有两种比较便捷的实现方式:第一种,将该带有亲水涂层的导尿管和润湿液一起密封包装在不透气的包装袋内,亲水涂层和润湿液在储存期间持续的保持接触。 For wetting a hydrophilic lubricious coating, more convenient There are two kinds of ways: First, the catheter with the wetting fluid and sealed with a hydrophilic coating packaged in airtight bags inner, hydrophilic coating and a wetting liquid during storage to maintain constant contact with. 该方式由于要求包装材料不透气,不能采用环氧乙烷气体灭菌,只能采用辐照灭菌,因此对包装、导管和涂层材料的要求都较高,由于较高的材料成本导致过高的产品价格,运输储存的成本较高。 Since this embodiment requires a gas-impermeable packaging material, it can not be used ethylene oxide gas sterilization, radiation sterilization can only be used, so the packaging, the catheter and the coating material requirements are high, due to higher material costs result in over high prices, high cost of transport and storage. 该实现方式主要的不足在于打开包装后润湿液容易溢出,给使用带来不便,同时容易造成身边环境的污染。 The implementation of major drawback is that the wetting liquid after opening the package easy to overflow, to use the inconvenience, but likely to cause pollution of the environment around. 第二种,为了避免第一种实现方法出现的不足(材料成本高、润湿液溢出),采用了特别的结构设计和操作方法实现亲水涂层的润湿。 Second, to avoid insufficient to achieve a first method occurs (the material cost is high, the wetting fluid overflow), using a special structural design and method of operation to achieve wetting of a hydrophilic coating. 主要的实现方法是:用润湿液贮器封装润湿液,亲水导尿管管与润湿液贮器一起包装在包装袋内,使用时通过施加外力打开润湿液贮器,润湿液流出到包装袋内,亲水导尿管插入段在润湿液中浸泡一定的时间(一般推荐时间为不少于30s),然后拆开包装袋取出亲水导尿管,此时亲水导尿管表面已成润滑状态,可以舒适地使用。 The main implementation is: package with a wetting fluid container a wetting fluid, a hydrophilic urinary catheter wetting fluid container tube and packaged together in a packaging bag, by applying an external force to open the wetting fluid container when in use, a wetting liquid flows into a package, a hydrophilic urinary catheter insertion section some time to soak in the wetting fluid (typically less than the recommended time is 30s), then open the packaging bag unloading hydrophilic urinary catheter, this time the hydrophilic catheter surface has become lubrication, can comfortably use. 第二种方法比第一种方法实现了减低包装材料成本,减少了润湿液溢出造成环境污染的风险,但是实际状况下仍存在一些不足,例如,为了使润湿液浸泡到导尿管整个可插入段,仍需要有较大量的润湿液,虽然目前也有通过收窄导尿管可插入段包装内腔的大小来实现减少润湿液的需求量,但减少润湿液的效果不明显,且易造成导管表面与包装袋粘结不易拔出;又如,亲水导尿管插入段在润湿液中浸泡一定的时间,延长了操作等待时间,病人在紧急状态下不能快速得到使用,造成一定程度的不便。 The second method to implement than the first method of packaging to reduce material costs, reduces the risk of wetting liquid overflow of environmental pollution, but the actual situation there are still some deficiencies, for example, to make the wetting liquid to soak the entire catheter section can be inserted, still a need for a greater amount of dampening fluid, although there may be inserted through the narrowed segment size package catheter lumen to achieve a reduction of the demand wetting fluid, but little effect to reduce wetting fluid , and could easily lead the catheter surface with the adhesive not easy to pull the bag; another example, the hydrophilic urinary catheter insertion section some time to soak in the wetting fluid, the extended operation waiting time, the patient can not be obtained quickly in an emergency use , resulting in a certain degree of inconvenience.

[0005] 综上分析两种主流的导尿管润滑形式,同时对比了两种亲水导尿管管的润湿实现方式。 [0005] Analysis of the two main catheter Lubrication In summary, while the comparative two ways to achieve wetting of the hydrophilic urinary catheter tube. 就亲水导尿管管润湿实现的第二种方式中存在的润湿液用量大、操作需要等待、易造成涂层表面与包装粘结和润湿液溢出等不足,本发明提供了一种亲水导尿管管的润湿实现方案,避免了上述不足的同时能有效为亲水涂层润滑导尿管进行润湿。 The amount of the hydrophilic urinary catheter wetting fluid to a second embodiment of the present tube to achieve wetting large, wait operation, easy to cause the adhesive coated surface of the package and the lack of dampening fluid overflow, the present invention provides a wetting a hydrophilic urinary catheter to achieve simultaneously seed tube embodiment, to avoid the above deficiencies can effectively wetting a hydrophilic urinary catheter coating lubrication.
