Description

自动止液护帽
(一)技术领域
本实用新型属于医疗器械领域，具体涉及自动止液护帽。 
(二)背景技术
目前，不带静脉针的输液器一般采用护帽形式保护输液器末端，以确保整支输液器的安全无菌。带护帽不带静脉针的输液器从生产，经灭菌，到用户拆开包装使用，期间始终保持无菌状态。但在使用输液器之前需要排净输液器内的气体，这段时间里会致使输液器末端的污染，甚至导致整支输液器被污染而使用者不自知。 
对于一些患者需要严格控制给药量，一次性输液器排气过程中难以避免药液的浪费，药液的浪费量难以计量，往往患者使用的药液量与医生开出的量是有一定差距。 
(三)发明内容
需要解决的技术问题是：避免输液器排气过程中药液的浪费，保持输液器末端的无菌状态更持久。 
本实用新型是可以采用下述技术方案实现的：自动止液护帽由排气口(3)、防滑棱(1)、密封套(2)、焊接线(4)、疏水膜材(5)、密封棱(6)组成，如图1、2、3所示，焊接线在超声波焊接时使用。密封棱采用双螺纹设计，使得自动止液护帽与接头的连接更紧密，防止漏液。防滑棱采用半圆柱形支撑自动止液护帽，增加了使用时的摩擦力，加固了自动止液护帽的强度，防止外力损伤。疏水膜材使气体通过、阻住液体，因而可通过排气口排净输液器内气体同时药液不流出，有效避免了药液的浪费。自动止液护帽壳体由注塑机一次性注塑而成，壳体是指排气口、防滑棱、密封套、焊接线、密封棱组成的整体。疏水膜材采用超声焊接，或热熔焊接，或胶粘，或互锁压方式固定在壳体上，护冒内部采用一定锥度设计，方便脱模。自动止液护帽壳体采用聚丙烯(PP)，或聚乙烯(PE)，或丙烯腈-苯乙烯-丁二烯共聚物(ABS)，或聚甲基丙烯酸甲酯(PMMA)医用材料。 
本实用新型还可以采用下述技术方案实现：自动止液护帽由上盖(1)，底座(2)，疏水膜材(3)，鲁尔锁定接口(4)，鲁尔内圆锥面(5)，压膜筋(6)，防滑棱(7)组成，如图4、5、6所示。鲁尔内圆锥面设置一定锥度。鲁尔锁定接口采用双螺纹设计，使得自动止液护帽与接头的连接更紧密，防止漏液。防滑棱采用锯齿形设计，增加了使用时的摩擦力，加固了自动止液护帽的强度，防止外力损伤。上盖设置两个半圆形镂空，可使透过疏水膜材的气体通过，并设置了支撑疏水膜材用的横梁，上盖高度范围为1～20mm。底座侧面设计半椭形凹槽，凹槽的长轴长范围为1～10mm，短轴长的范围为0～2mm，上盖相应位置设计有相对大小的半椭形凸槽，整个凹凸设计环绕在上盖与底座的整个侧面，此项设计是为了使上盖与底座的配合更紧密，防止疏水膜材与上盖的脱落。疏水膜材使气体通过、阻住液体，因而可通过上盖排净输液器内气体同时药液不流出，有效避免了药液的浪费。自动止液护帽壳体由注塑机一次性注塑而成，壳体是指底座， 鲁尔锁定接口，鲁尔内圆锥面，防滑棱组成的整体。压膜筋在上盖底部，压膜筋与上盖整体注塑。压膜筋在超声焊接时使用：利用超声焊接将疏水膜材固定在上盖上，将焊有膜材的上盖压进底座。疏水膜材采用超声焊接，或热熔焊接，或胶粘，或互锁压方式固定在自动止液护帽内。自动止液护帽壳体、压膜筋和上盖采用聚丙烯(PP)，或聚乙烯(PE)，或丙烯腈-苯乙烯-丁二烯共聚物(ABS)，或聚甲基丙烯酸甲酯(PMMA)医用材料。 
本实用新型与现有技术相比，产品结构简单，外观漂亮，制造工艺简单，生产成本低，可以有效避免药液的浪费，提高了输液治疗的安全性、有效性，保持输液器末端的无菌状态更持久，使用方便，牢固度可靠，适合推广使用。
