The invention discloses a freeze-drying drug application device, which belongs to the field of freeze-dried medicine, including a drug cavity, a recovery solvent cavity and a sealing strip. The drug cavity is arranged adjacent to the recovery solvent cavity. The seal is arranged between the drug cavity and the recovery solvent cavity. The seal strip separates the drug cavity from the recovery solution cavity, when the cavity is restored to the solvent. When the solvent is restored to apply pressure, the recovery solvent can break the sealing strip open so that the recovery solvent is mixed with the freeze-dried medicine; the bottom of the drug cavity is set up the exhaust pipe, and the exhaust valve is set outside the exhaust pipe, and the bottom of the solvent cavity is restored and the infusion tube and the injection pipe are set at the bottom of the solvent cavity. The freeze-dried drug dispensing device of the invention can easily mix freeze-dried drugs and recover solvents, and the whole mixing process is carried out in a sealed sterile cavity, and the possibility of drug contamination is eliminated. The device injects different kinds of recovery solvents according to different freeze-dried drugs and is convenient for mixing. The device is a disposable medical device.
【技术实现步骤摘要】
一种冻干药物施药装置
本专利技术涉及冻干药物领域,具体地说,本专利技术涉及一种冻干药物施药装置。
技术介绍
真空冷冻干燥,也称升华干燥。其原理是将材料冷冻,使其含有的水份变成冰块,然后在真空下使冰升华而达到干燥目的。冻干药物是一种使用冻干技术处理药物的方法,通过冻干可以延长和标准化在液态中最小的药物产品的保质期。冻干是通过将液体药物直接转化为蒸汽而没有液体的中间形态,而从冷冻药物中去除液体部分的方法,冻干的主要步骤为冷冻(从液态至固态),初级干燥(升华)和二次干燥(用于除去非冷冻液体)。冻干后的药物使用时需要与复原溶剂混合后才能给患者输液或者注射,现有技术将冻干药物与复原溶剂分开包装,使用时用注射器在药瓶内混合,复原溶剂根据药物种类的不同选择也不同,上述混合过程中可能产生药物污染的风险,由于冻干过程需要先降温后升温,经过上述温度变化复原溶剂可能失效,所以不能将药物和复原溶剂一起进行冻干处理。
技术实现思路
本专利技术所要解决的技术问题是提供一种冻干药物施药装置,该装置不会出现药物混合被污染的问题,方便混合施用冻干药物。为了解决上述技术问题,本专利技术所采用的技术方案是:一种冻干药物施药装置,包括药物腔、复原溶剂腔和密封条,所述药物腔与复原溶剂腔相邻设置,密封条设置在药物腔与复原溶剂腔之间,密封条将药物腔与复原溶剂腔隔开,当对复原溶剂腔内的复原溶剂施加压力时复原溶剂可以将密封条冲开使复原溶剂与冻干药物混合;所述药物腔的底部设置排气管,排气管外设置单向排气阀,所述复原溶剂腔的底部设置输液管和注液管。优选的,所述复原溶剂腔底部还设置备用注液管,备用注液管设在注液管旁 ...
