Description

一种反压式医药用瓶及其配药装置和注射装置组合件技术领域 An anti-pressure medicine bottle and dispensing member and the injection device TECHNICAL FIELD composition

[0001] 本发明涉及医疗器械领域,特别涉及一种反压式医药用瓶及其配药装置和注射装置组合件,即反压式西丁瓶及其配药装置和注射装置组合件。 [0001] The present invention relates to the field of medical devices, and particularly relates to an anti-pressure medicine bottle and dispensing means and the assembly of the injection device, i.e. cefoxitin trans-pressure bottle and dispensing means and the injection device assembly.

背景技术 Background technique

[0002] 众所周知,常见的医药用瓶有安瓿瓶、西林瓶、卡式瓶、预充式注射器等。 [0002] It is well known common pharmaceutical bottles ampoules, vials, bottles card, prefilled syringes and the like.

[0003] 安瓿瓶是用火焰密封的玻璃小瓶,常用于存放注射用的药物以及疫苗、血清等,其清洗烘干灭菌和灌装工艺成熟,灌装中的封口采用火焰加热已灌装药液的安瓿瓶颈部,待其融化后,用拉丝封口工艺使安瓿瓶密封。 [0003] The ampoule was flame sealed glass vial for injectable use commonly used for storing drugs and vaccines, serum, etc., which washing and drying the sterilization and filling process maturity, filling and sealing the drug by flame heating the filling liquid ampoule neck portion, until melted, using a wire sealing process so that the seal ampoule. 但因其封口采用火焰加热,不能适用于非耐热性药物;另一方面在灌封过程中,存在由于高温引起药液化学反应从而影响药品质量的风险。 However, because the sealing flame heating, heat can not be applied to non-drug; on the other hand in the potting process, since the presence of liquid due to high temperature chemical reactions affecting the quality of the risk of the drug. 在使用时,需要用砂轮切割瓶颈、徒手掰开或硬器打开安瓿瓶颈,利用注射器抽吸安瓿瓶内的药物进行注射,注射器直接接触药品。 In use, to be cut with a grinding wheel bottleneck, break apart, or hard hand an ampoule open bottleneck, using a syringe pump drug injection ampule, syringe direct contact with drugs. 在配制操作过程中极容易导致粘于瓶壁的砂轮末及玻璃屑掉入药瓶内,毒性药液与配制人员皮肤直接接触造成感染,安瓿瓶打开过程中药液与外界空气接触,存在二次污染问题,且其所生产产品的剂量大小受限。 During operation formulation very easily lead to the end of the grinding wheel and adhered to bottle wall glass chips fall into the vial, toxic chemical formulator direct contact with the skin caused by infection, during the opening of the ampoule liquid in contact with the outside air, the presence of two secondary pollution problems, and the products they produce dose size is limited.

[0004] 西林瓶因多用其盛装早期盘尼西林而得名,西林瓶又称钠钙玻璃制注射剂瓶,是一种胶塞封口的小瓶子。 [0004] Vial containing early due to its multi-named penicillin, also known as soda lime glass vials made of injection bottle, a vial stopper sealing. 有棕色,透明等种类,一般为玻璃材质,其瓶颈部较细,瓶颈以下粗细一致,瓶口略粗于瓶颈,略细于瓶身,可用做碘酒瓶,注射液瓶,口服液瓶等。 Brown, transparent type, etc., usually made of glass, thin section bottleneck, the bottleneck of the same thickness, slightly thicker than the bottleneck bottle, the bottle is slightly finer than, be used as iodine bottle, bottle injection, oral liquid bottles . 当用作注射液瓶使用时,与安瓿瓶相类似,配制操作过程繁琐,需要利用注射器抽吸西林瓶内的药物进行注射,在用注射器抽吸西林瓶内的药物过程中,由于瓶内产生负压难于吸出药液,需加大抽吸力度、让针管内产生负压并倒立时药液吸入针管,但拔出瞬间有会造成空气吸入针管,存在二次污染问题。 When used as an injection liquid bottle, ampoule and similar to the preparation process complicated operation requires the use of a syringe pump injection drug resistant bottle, in the process of pumping the drug vial with the syringe amoxicillin, since a bottle negative pressure is difficult to suck out the liquid, the need to increase the intensity of aspiration, let a negative pressure within the needle and the liquid suction needle when inverted, but there is cause instant pull air into the syringe, there is no secondary pollution.

[0005] 卡式瓶瓶口装有胶塞并用铝盖密封,尾部用橡胶活塞密封,类似于预装药液的玻璃针管注射器,另配有注射用双通导针针头和推杆。 [0005] Cassette bottle finish with an aluminum seal and rubber stopper, sealed with a rubber plunger tail, similar to the pre-chemical glass syringe needle, comes with a two-way injection syringe needle and the push rod guide. 使用过程导针针头扎入瓶口胶塞,推杆放于瓶尾部的橡胶活塞上用力,药液在活塞的压力下注入人体。 Needle use guide bar into the bottle stopper, the plunger force placed on the end of the rubber piston bottle, liquid under pressure into the body of the piston. 由于卡式瓶后活塞没被铝盖用压力密封、在高温灭菌时药液膨胀极易使活塞脱落,属无法进行终端灭菌产品。 Since the card-type aluminum cap bottle is not sealed piston pressure, at high temperature chemical sterilization expansion piston off easily, is not terminally sterilized products. 卡式瓶使用过程药液不与注射器任何部件接触,解决了注射时二次污染问题。 Cassette bottle is not in contact with liquid during use syringe of any member, to solve the problem of secondary pollution injection. 但是,由于卡式瓶为非终端灭菌产品,其尾部用橡胶活塞密封,使用时又能够滑动,致使其密封的可靠性工艺要求高,生产成本大,生产剂型选择受局限。 However, since the non-terminal sterilization cassette bottle product, the tail with a rubber piston seal, the use of time and capable of sliding, resulting in a high sealing reliability of the process requires large production costs, the production of a dosage form selected subject to the limitations.

[0006] 预充式注射器是将注射药物直接灌装在玻璃注射器中,且玻璃注射器上安装有注射针头,将注射器和药液包装容器合二为一,使用时直接注射,使用非常方便且保质期与安瓶和西林瓶一样。 [0006] The pre-filled syringe is filled in directly injectable pharmaceutical glass syringe, and mounted on a glass syringe with a needle, syringe and combined liquid containers, direct injection use, easy to use and shelf life Like ampoules and vials. 它有以下几个非常突出的优点:(1)使用时无交叉感染,病房中不洁净的空气接触不到药品,做到正安全注射;(2)医生护士使用极为方便,无需抽药,无需安装针头,直接注射,一次性使用;(3)药品充分利用,无残留药液;(4)野外场合适合自我注射。 It has several very prominent advantages: no cross-infection (1) use, ward unclean air out of the reach of drugs, so being safe injection; (2) the doctors and nurses extremely easy to use, no need to smoke drugs, no a needle mounting, direct injection, disposable; (3) full use of drugs, no residual liquid; (4) field situation for self-injection. 但是,预充式注射器同样适用于非终端灭菌产品,如生物活性疫苗等,而且其包材价格高昂,难于推广。 However, prefilled syringes are equally applicable to non-sterile end products, such as vaccines and other biological activity, and its packaging material expensive, and difficult to promote.

[0007] 对于大量药品来讲,其在药厂的生产包装、销售中的储运和医院的使用方式没有显著变化,尤其是药品的包装决定了医院使用方式,并且涉及配药普遍存在二次污染,全世界也没有理想的解决方案,不能实现药物生产和注射人体的无缝对接。 [0007] For a large number of drugs in terms of its production of pharmaceutical packaging, no significant change in sales of transportation and hospital use, especially for pharmaceuticals packaging determines the way hospitals, and involves dispensing common secondary pollution the world there is no ideal solution, can not achieve seamless drug production and injection of the human body.
