编辑同志:目前国内各地使用的安瓿几乎还都是直颈安瓿。直颈安瓿在开启使用时,用砂轮难锯痕,用手掰开时也易碎。安瓿容积越大,颈就越粗,更容易掰碎刺破手。因此,在使用时只好用镊子等将安瓿打开。但这种操作方法会使玻璃屑落入,影响药液的澄明度。为了考查对澄明度的影响,我们取2ml、10ml、20ml三种装有蒸溜水经检查澄明度合格的直颈安瓿各100支(在割颈及熔封时,安瓿颈要留长一些,以便在打开后能进行第二次熔封)。用镊子打开安瓿,马上进行第二次熔封,按《中国药典》进行澄明度检查,结果2ml 的70%,10ml 的81%,20ml 的97%有玻璃屑。因此说明用镊子打开安瓿这种操作方法,对药液澄明度的影响是严重的。安瓿愈大,玻璃屑落人的机会就愈多。使用前是合格的药品,在使用时却变成了
Editorial comrades: ampoules used throughout the country are almost all straight neck ampoules. Straight-neck ampoules in the open to use, with the grinding wheel difficult to mark, hand breaking apart when fragile. The larger ampoule, the more coarse the neck, the easier it is to break the broken thorn. Therefore, the use of forceps and so had to open the ampoule. However, this method of operation will fall into pieces of glass, affecting the clarity of the liquid. In order to examine the impact of clarity, we take 2ml, 10ml, 20ml three with clear water after inspection of the clarity of straight neck ampoules each 100 (in the neck cutting and sealing, ampoule neck to stay longer, so After opening can be a second fuse). Opened the ampoule with tweezers, and immediately carried out a second seal, according to the “Chinese Pharmacopoeia” for clarity examination, the results of 2ml of 70%, 81ml of 10ml, 20ml of 97% glass crumbs. Therefore, open the ampoule with tweezers this method of operation, the clarity of the liquid medicine is serious. The bigger the ampoule, the more chance the glass crumbs will fall. Before use is a qualified drug, it becomes in use
