Description

一种预封式溶液包装及便携式亲水性导尿管 技术领域
本发明属于医学、卫生学技术领域，涉及导管，尤其涉及一种预封式溶液包装及便携式亲水性导尿管。
背景技术
间歇性导尿管通常用于受尿失禁痛苦的患者或者无法进行自主排尿的人。在频繁活动的社会文化中，有能力自由离开家一天或者更长时间是生活的重要部分。为了适应这种需求，已经开发出一次性导尿管以便允许患者进行自主导尿。需要导尿的人每天通常会使用若干导尿管，因而需要一种既廉价又不牺牲安全性和舒适度的导尿管。
间歇性导尿管的较高的日使用率导致需要导尿的患者每当长时间离开家时都需要随身携带若干导尿管。包装好的导尿管倾向于大且笨重，从而导致难以分开地携带一定量的导尿管。
现行市场上的大多数导尿产品在外观、使用和回收上都有受到携带、使用时间或地点的约束，并且大多采用纸塑或全塑袋包装，包装柔软、易弯折，体积大，透明的薄膜更不利于病患携带时隐私的保护，经常给使用者带来一定的尴尬。而且目前市场上便于携带的导尿管一种是用润滑剂润滑导管表面，患者使用后润滑剂容易留在患者身体或身上其他部位，很不方便；另外一种是把亲水性导尿管长期浸泡在水溶液中，时间长后比较容易滋生微生物，或者对亲水性表面产生一定的破环。
发明内容
本发明针对上述问题，提供一种预封式溶液包装及便携式亲水性导尿管。
本发明的目的可以通过下述技术方案来实现：一种预封式溶液包装，包括管体、热封膜、封闭溶液盖体、溶液和针；所述管体包括内管部和外管部，所述内管部和外管部的两端均为开口，所述内管部设置于外管部内，并且内管部的长度小于外管部的长度，内管部的一端与外管部的一端相连接，内管部的另一端热封有热封膜，所述外管部的另一端与封闭溶液盖体连接，所述内管部的外壁、外管部的内壁、热封膜和封闭溶液盖体的内侧表面围成一密封的溶液腔，所述溶液腔内设有溶液；所述封闭溶液盖体包括盖顶面和盖侧壁，所述盖顶面的外侧表面形成有按压部，盖顶面的内侧表面垂直设有一根以上的针，所述按压部、针和热封膜 三者的位置相对应，所述针的尾部与按压部相连接；当所述按压部未受到朝向盖顶面内侧的外力时，所述针位于溶液腔内，并且针的针尖与热封膜之间具有间距，避免在未使用之前，针触碰到热封膜或戳破热封膜，造成溶液腔内的溶液流出；当所述按压部受到朝向盖顶面内侧的外力，使得针的针尖戳破热封膜时，所述溶液腔内的溶液从热封膜上的戳破口流至内管部内。
优选地，所述按压部凸出于盖顶面的外侧表面。更优选地，所述按压部与针的尾部与连接为一体。
进一步地，所述针的表面设有一条以上的溶液防堵凹槽。更进一步地，所述溶液防堵凹槽呈长条形且两端分别向针的针尖和针尾延伸。
可选地，所述针呈圆锥状，所述溶液防堵凹槽的两端分别延伸至针的针尖和针尾。或，所述针的针尖部分呈圆锥状，针的其余部分呈圆柱状，所述溶液防堵凹槽的两端分别延伸至针的针尖和针尾。
一种便携式亲水性导尿管，包括上述的预封式溶液包装、封闭导尿管盖体和亲水性导尿管；所述预封式溶液包装的管体的外管部的一端与封闭导尿管盖体连接，所述亲水性导尿管包括导尿管管体和导尿管接头，所述导尿管管体的一端与导尿管接头连接，导尿管管体的另一端封闭且其上设有小孔，导尿管管体的表面设有亲水性涂层，所述亲水性导尿管按照导尿管管体的另一端朝向预封式溶液包装的管体的内管部内的方向装入内管部内，所述导尿管接头的顶端露出于管体的外管部的一端端面。
进一步地，还包括橡胶垫，所述橡胶垫设置于预封式溶液包装的管体的外管部的一端与封闭导尿管盖体的连接处。更进一步地，所述预封式溶液包装的管体的外管部的一端与封闭导尿管盖体为螺纹连接。
与现有技术相比，本发明的有益效果：设计了一种包装，采用双层的管体，管体的外层与封闭溶液盖体、热封膜构成密封的溶液腔，从而将溶液预封。管体的内层与相配套的封闭导尿管盖体来密封放置亲水性导尿管。携带时，包装内的溶液与亲水性导尿管相互不接触。使用时，只需按压封闭溶液盖体的相应部位，使针刺破密封溶液的热封膜，溶液就可以流入管体内层内并淹没亲水性导尿管，达到使表面亲水性涂层溶胀润滑的目的，然后取下封闭导尿管盖体，从管体内层取出亲水性导尿管就可以进行使用，使用完后，将亲水性导尿管放回即可。整个产品的体积小，便于独立携带，在使用和回收方面都很方便。管体、封闭溶液盖体、封闭导尿管盖体采用非透明的热塑性材料制成，可以保护隐私且制造成本低。而且其内部可以放置各种规格的亲水性导尿管，适用性好。

其中，所述管体1可以采用热塑性材料或硅胶材料制成，热塑性材料可以是PVC、聚氨酯，硅胶材料可以是乳胶。所述内管部101和外管部102的横截面可以为圆形，并且内管部101和外管部102同轴设置，对应的所述按压部303和针5可以设置于盖顶面301的中心。所述热封膜2采用不透水的热封材料制成，热封材料可以是塑料膜或铝塑膜。所述封闭溶液盖体3和针5可以采用一体式结构。所述封闭溶液盖体3和针5均可以采用热塑性高分子材料制成。所述按压部303可以凸出或齐平或内凹于盖顶面301的外侧表面，只要按压部303能够被朝向盖顶面301内侧按压即可，本实施例中，按压部303采用凸出于盖顶面301的外侧表面的设计，便于按压操作。
实施例2
预封式溶液包装，与实施例1的区别在于针5的数量，参见图4和图5，所述针5的数 量为一根。
其余数量的针5可以参考实施例1和实施例2进行设置。
实施例3
在实施例1和实施例2的基础上的预封式溶液包装，考虑到在针5的针尖戳破热封膜2后，针5有可能会堵住热封膜2上的戳破口，使得溶液腔内的溶液4无法顺利流出，故在针5的表面设有一条以上的溶液防堵凹槽501，便于溶液腔内的溶液4沿着溶液防堵凹槽501从戳破口流出，合理避免了针5堵住热封膜2上的戳破口。所述溶液防堵凹槽501呈长条形，溶液防堵凹槽501的两端分别向针5的针尖和针尾延伸，至于溶液防堵凹槽501的端部是否通至针5的针尖和/或针尾则不作限制，只要保证溶液腔内的溶液4沿着溶液防堵凹槽501能从戳破口流出即可。
本实施例中，参见图6和图7，示出了两种常规形状的针5及其上的溶液防堵凹槽501的布置结构。参见图6，所述针5的整体呈圆锥状，针5的表面设有两条溶液防堵凹槽501，所述溶液防堵凹槽501的两端分别延伸至针5的针尖和针尾。参见图7，所述针5的针尖部分呈圆锥状，针5的其余部分呈圆柱状，针5的表面设有三条溶液防堵凹槽501，所述溶液防堵凹槽501的两端分别延伸至针5的针尖和针尾。图8和图9分别示出上述两种形状的针5从在溶液腔内到戳破热封膜2的过程。其余形状的针5和溶液防堵凹槽501的布置结构可以参考图6和图7进行设置。
实施例4
参见图10至图11，一种便携式亲水性导尿管7，包括实施例1-3的预封式溶液包装、封闭导尿管盖体6和亲水性导尿管7，其中，所述预封式溶液包装的针5的表面设有溶液防堵凹槽501。
所述预封式溶液包装的管体1的外管部102的一端与封闭导尿管盖体6连接，本实施例中，外管部102的一端与封闭导尿管盖体6为螺纹连接，具体地，外管部102的一端外壁设置外螺纹，封闭导尿管盖体6的内壁设置相配合的内螺纹，也可以是外管部102的一端内壁设置内螺纹，封闭导尿管盖体6的外壁设置相配合的外螺纹；封闭导尿管盖体6可以采用顺时针5拧开的设计，便于从预封式溶液包装的管体1的外管部102上取下。所述外管部102的一端与封闭导尿管盖体6的连接处还设有橡胶垫8，所述橡胶垫8避免溶液4流入从连接处的缝隙流出，保证连接处的密封性。
所述亲水性导尿管7属于现有技术，常规的亲水性导尿管7包括导尿管管体701和导尿管接头702，所述导尿管管体701为软管，导尿管管体701的一端与导尿管接头702连接， 导尿管管体701的另一端封闭且两侧分别设有一小孔，所述导尿管管体701的表面设有亲水性涂层，遇水溶液4浸泡后，亲水性涂层会溶胀润滑，使导尿管管体701表面的摩擦阻力减小，插入更轻松，从而减少病人痛苦，所述亲水性导尿管7设置于预封式溶液包装的管体1的内管部101内。
其中，所述预封式溶液包装的管体1的内管部101和外管部102及封闭导尿管盖体6的横截面可以为圆形，内管部101和外管部102同轴设置，对应的预封式溶液包装的按压部303和针5可以设置于盖顶面301的中心。所述预封式溶液包装的溶液4为水溶液4或其他消毒溶液4。所述封闭导尿管盖体6可以采用与预封式溶液包装的管体1相同的材料制成，如热塑性材料或硅胶材料，热塑性材料可以是PVC、聚氨酯，硅胶材料可以是乳胶。
安装时，使亲水性导尿管7的导尿管管体701的另一端朝向预封式溶液包装的管体1的内管部101内，将导尿管管体701沿着内管部101置入内部，再使导尿管接头702的顶端露出于管体1的外管部102的一端端面，这样便于将亲水性导尿管7从管体1的内管部101内取出，之后在管体1的外管部102的一端套上橡胶垫8并装上封闭导尿管盖体6，使管体1的内管部101内处于密封状态即可。
使用时，参见图12，按压预封式溶液包装的封闭溶液盖体3上的按压部303，使按压部303连接的针5的针尖戳破热封膜2，溶液腔内的溶液4沿着针5的溶液防堵凹槽501从热封膜2的戳破口流入管体1的内管部101内，进而流向亲水性导尿管7。当流入到内管部101内的溶液4达到一定程度时，一部分溶液4会从亲水性导尿管7的导尿管管体701的另一端的小孔流至导尿管管体701的内部。由于溶液腔和管体1的内管部101的内部存在压力差，溶液腔内的溶液4和管体1的内管部101内的溶液4最终达到一定平衡，实现淹没亲水性导尿管7的导尿管管体701。之后，拧开封闭导尿管盖体6，取出亲水性导尿管7即可使用，使用完后，可以将亲水性导尿管7放回管体1的内管部101内，再装上封闭导尿管盖体6即可。
应当指出，对于经充分说明的本发明来说，还可具有多种变换及改型的实施方案，并不局限于上述实施方式的具体实施例。上述实施例仅仅作为本发明的说明，而不是对本发明的限制。总之，本发明的保护范围应包括那些对于本领域普通技术人员来说显而易见的变换或替代以及改型，且以所附权利要求为准。
