The utility model discloses a preparation device of eyedrops containing plasma and platelets, which comprises a negative pressure aseptic cavity composed of an injection tube, a filter chamber, a guide tube, a shunt tube and a plurality of eyedrops bottles. The upper end of the injection tube is provided with a rubber sealing plug, the lower end of the injection tube is connected with the upper end of the filter chamber, the lower end of the filter chamber is connected with the upper end of the guide tube, and the lower end of the guide tube is connected. The over-flow tube is connected with each eyedrops bottle, and a 2.5-3.5 micron pore size filter membrane is arranged in the middle of the filter chamber for removing blood cell components larger than 2.5-3.5 micron. The device for preparing eyedrops containing plasma and platelet of the utility model obtains platelet filtrate with plasma through membrane filtration method in a negative pressure sterile chamber, and obtains disposable eyedrops by filling multiple single-dose eyedrops bottles under negative pressure. The eyedrops are obtained in about 15 minutes, with high preparation efficiency, platelet-containing eyedrops, easy operation, and can be manufactured by medical staff or patients themselves in ordinary space. Prepare.
【技术实现步骤摘要】
含血浆及血小板滴眼剂制备装置
本技术涉及医药领域,具体涉及一种含血浆及血小板滴眼剂制备装置。
技术介绍
自体血浆制成的血源性滴眼液在眼表疾病的临床治疗中得到了广泛的应用,并取得了良好的临床疗效。研究表明,用含有血小板的自体血浆做成滴眼制剂代替药物滴眼液,对于特定眼部疾病能发挥更好的治疗效果,且药毒副作用更低,其效果也优于自体血清滴眼液。但是,血源性滴眼液中不宜添加防腐剂,以避免对角膜上皮的毒性作用,提取和配置血源性滴眼液的过程应该保证严格的无菌操作,以避免造成污染。技术专利(ZL200720013742.3)公开了一种自体血清眼水采集制备系统,包括采血装置、血清稀释瓶和分装装置,该系统需要室温静置2小时或4℃静置48小时,以形成血清。该套系统需要分段与外部空气连通,非密闭无菌。其静置步骤至少需要2小时,且静置方法获得的是血清,不是血浆,也不含血小板,对某些眼部疾病的治疗效果不佳。
技术实现思路
本技术的目的是提供一种制备效率高、操作方便、含血浆及血小板的滴眼剂制备装置。为实现上述目的,本技术的技术方案是:一种含血浆及血小板滴眼剂制备装置,包括由注射管、过滤腔、导流管、分流 ...
