Abstract

本实用新型为一种橡塑复合膜封装式负压采血管,用于各类检验用血的采集,由透明塑料管和橡塑复合密封膜构成;透明塑料管口部有加厚部分,橡塑复合密封膜由丁基橡胶层和塑料膜层两层复合而成;管口带加厚部分的透明塑料管和橡塑复合密封膜以热塑封装方式牢固结合为一体。橡塑复合密封膜,上层为丁基橡胶层起密封作用,针刺后又能复原,以保持真空度,下层为塑料薄膜层,用于与塑料试管热塑粘合,并加强复合薄膜的保真空性能。产品保真空期大于2年,此技术能大幅度降低采血管的生产成本与价格。

Description

橡塑复合膜封装式负压采血管
(一)技术领域:本实用新型涉及一种负压采血管,特别是橡塑复合膜封装式负压采血管,适用于各类抗凝血的采集与检验,属于医疗器械技术领域。
(二)背景技术:
目前国内外市场上开始普遍采用负压采血管,其构造均是由玻璃或透明塑料试管,医用无毒丁基橡胶塞,彩色塑帽三部分构成;而其中丁基橡胶塞的成本占采血管成本的一半以上,丁基橡胶又是进口物资,随全国大中小医院,负压采血管的大量使用,丁基橡胶将成为紧缺物资。
(三)发明内容:
本实用新型的目的是为解决目前医用负压采血管的成本过高及防止采血管内容物污染问题,本实用新型提供一种橡塑复合膜封装式负压采血管,构造如图1-3所示,由透明塑料管(1)和橡塑复合密封膜(2)构成;透明塑料管(1)口部有加厚部分(1a),橡塑复合密封膜(2)由丁基橡胶层(2a)和塑料膜层(2b)两层复合而成;管口带加厚部分(1a)的透明塑料管(1)和橡塑复合密封膜(2)以热塑封装方式牢固的结合为一体,透明塑料管(1)中预先放进附合剂,附合剂为抗凝或促凝剂,以检验项目而定。试管内抽真空,试管外壁贴上用于记载检验项目的标签。
橡塑复合膜由药用丁基橡胶层与塑料薄膜层叠加粘合组成,总厚只有0.5~1.0mm,预先压制为成品,裁制为与试管口尺寸相等的圆片使用,上层为橡胶层,起密封作用,针刺后又能复原,以保持真空度,下层为塑料薄膜层,用于与透明塑料试管热塑粘合,开加强复合薄膜以保持真空性能。产品的保真空期大于2年,试管口的加厚部分(1a)能增加橡塑复合密封膜的粘贴面积和增加试管强度。
本实用新型的优点之一是能够大幅度降低采血管的生产成本与价格,简化生产工艺,节省大量进口丁基橡胶材料,减少成本,又简化了工序,更适合于自动化流水线生产。其二是其密封程度和保真空期大大优于橡胶塞的密封办法,其三因本行业标准规定:不得用手触及塞子,为此国外产品还增加了安全帽,这就更增加了制造工艺复杂性和生产成本,此产品的生产使用均适宜于机械办法而可以淘汰手工操作,所以不需要增加安全帽。其四因橡塑复合膜较胶塞薄,采血穿刺就更容易。
(四)附图说明

图2橡塑复合密封膜立体图
图3图2中的A细部,橡塑复合密封膜层间构造剖面示意图
负压采血器在国内已开始全面推广普及,生产厂家将面临广泛的市场竞争,而市场竞争的焦点在于价格:
进口的负压采血器(以美国BD公司产品为代表),其采血针2.20元/支,负压采血管1.14元/支(合计3.60元人民币/套),目前国产的负压采血器(以北京与湖南浏阳产品为例),其产品每套出厂价为1.20元左右,其中负压采血管0.65元/支,采血针0.55元/支。但是目前国内还在传统使用的一次性塑料注射器采血,其总成本不到0.60元/套(注射器、试管与附加剂等),为此,要全面推广使用负压技术不仅仅是传统习惯的问题,更主要的是价格问题。中国还是一个不发达的发展中国家,广大民众的生活水平、医疗水平与医疗成本,决不能与国外发达国家相比,要全面普及负压采血技术,如何大幅度降低其成本与价格是关键。
橡塑复合膜封装式负压采血管,其总材料成本为0.10元/支左右(其中塑料管0.06,复合膜0.03,标签0.01),出厂销售价格将在0.20元/支以下,其价格将是国产产品的1/3,进口产品的1/6,无疑将有极大的竞争(包括与传统注射器的竞争)潜力。
中国是一个十多亿人口的大国,采血器的社会需求量巨大,大城市的一所医院每年的需求量将是数十万支、上百万支(尤其是现在采用多项目采血,每个病人需要采多支血样,需要多支负压采血管,那么该实用新型无疑将发挥极大的经济效益与社会效益。
(五)具体实施方式:
图1~3是本实用新型的实施例图,口部有加厚部分(1a)的透明塑料管(1),丁基橡胶层(2a)与塑料膜层(2b)经叠合粘合制成总厚为0.5~1.0mm的橡塑复合密封膜,在塑料管底部喷注附加剂(抗凝或促凝剂)将透明塑料管(1)口部端面与橡塑复合密封膜在自动机械设备内,抽真空和热塑封装。
