药房分裝药液一般多系虹吸管分裝法,或用量杯逐瓶倒入投药瓶,视达最高刻度后停止灌注,混悬液尚应时常攪拌,因此精神紧張,費时,费力。鑒于此,作者長期以来想寻求一种:药液自动分裝装置。最初,迷信洋法,想一步实現机械化,而设计了附有貼箋裝置的“药液自动分裝机”,但是没有人制造。党指出“土法先上馬”后,作者采用土法,改变了研究方向:先是定量分裝,结果,因投药瓶誤差很大,如100ml瓶,最大誤差为-24%,即实际容量为76ml,所以有的液面超过最上刻度,有的却装不滿,不便患者服药。同时發現,虽投药瓶誤差大,但自瓶底至最高刻度的距离却都相等。于是,作者应用了虹吸原理,經过百余次实驗,終于制成“药液自动分裝器”(下簡称分装器)。
The pharmacy dispensing liquids are generally made up of siphon dispensing methods, or the dosage cups are poured into bottle by bottle. After the maximum scale is reached, the pours are stopped. The suspension should be stirred constantly, so it is stressful, time-consuming and laborious. In view of this, the author has long sought a solution: automatic liquid dispensing device. At first, superstitiously, in order to realize mechanization in one step, he designed a “liquid automatic dispensing machine” with a sticker device, but no one made it. The party pointed out that after the “land method was first launched,” the author used the soil method to change the direction of research: first quantitative dispensing, the results, due to errors in the injection bottle, such as 100ml bottles, the maximum error is -24%, that is, the actual capacity is 76ml, so some liquid level exceeds the upper scale, but some are dissatisfied, inconvenience patients medication. At the same time, it was found that although the error of the medicine bottle is large, the distance from the bottom of the bottle to the highest mark is equal. So, the author applied the siphon principle, and after more than a hundred experiments, he finally made the “liquid automatic dispenser” (hereinafter referred to as the subpackager).
