The instant mixing eyedrops bottle comprises a dust cap, a liquid outlet nozzle and its catheter, an outer bottle body and an inner compartment. The outlet nozzle is integrated and connected with the lower long catheter. The upper and middle parts of the long catheter have a round hole of moderate size on both sides of the symmetrical tube. The outer bottle body and the inner compartment are fixed together. There are the same round holes corresponding to the catheter in the inner compartment. When the outer wing of the nozzle is rotated, the two round holes of the catheter can be driven to coincide or dislocate with the two round holes of the compartment. When the eyedrops are not opened, the circular holes on the long catheter do not coincide with the circular holes on the inner compartment, the four holes are cross-distributed, the drug powder does not contact with the solvent, and the stability is good. When the patient is in use, the outer wing of the liquid nozzle is rotated so that the holes on the catheter can be transferred to the position coinciding with the holes in the inner compartment, the dust cap is tightened, the bottle body is shaken, the drug powder and solvent are passed through. Through the contact of small holes, nano-eye drops such as eye drops or nano-micelle eye drops are formed.

即用即混型滴眼液瓶
本技术涉及一种滴眼液瓶,特别是一种可以实现当用药时药物粉末与溶剂即时无菌条件下混合形成滴眼溶液,即用即混的滴眼液容器,属于药瓶包装容器领域。
技术介绍
由于现代生活节奏和方式的改变,手机和电脑成了人们必备的学习和娱乐工具,而由此带来的眼部疾病也越来越多,滴眼液是治疗眼部疲劳和疾病的重要手段,现在滴眼液的品种也越来越丰富,如纳米胶束滴眼液就是一种新兴的具有很大前景的滴眼液,专利技术人研究结果表明,环孢霉素A(CyclosporineA,CSA)的纳米胶束滴眼液不仅可以显著提高药物的疗效,而且具有更高的眼部耐受性,但却受到稳定性这一包括纳米胶束滴眼液在内的纳米眼用滴眼液所面临的普遍问题的限制,严重阻碍了CSA纳米胶束滴眼液的开发和临床应用。专利技术人的已有研究表明,在25℃的避光条件下,专利技术人研制的CSA纳米胶束滴眼液在3个月内能保持稳定,相比于已有技术及文献报道,稳定性已有大幅度提高,但离进一步开发和临床应用所要求的的稳定性时间仍不足。此外,一些药物,如利福平,在水溶液状态下药物分子不稳定,容易水解而失去药物活性,难以制备成水溶液性滴眼液,限 ...
