Be provided with the disposable use sterile dispensing device of defecator
Technical field
This utility model relates to field of medical article technology, particularly a kind of disposable use sterile dispensing device that is provided with defecator.
Background technology
State Bureau has issued the mandatory industry standard of pharmaceuticals industry: yy0804 " medicinal liquid translator requires and test method " on January 6th, 2010, and comes into effect on June 1st, 2012.
Domestic and international existing dosage adopts indirect method, and as made up a prescription by disposable syringe, this kind of method has following shortcoming:
(1) make up a prescription by repeatedly aspirating to realize, more complicated, multi-step operation increases workload;
(2) easily cause drug waste, make medicine residual in a large number in medicine bottle, syringe;
(3) because syringe needle easily infects in exposure air repeatedly;
(4) aqueous injection glass disintegrating slag is easily pumped in liquid bottles;
(5) disposable syringe, because internal surface area is large, is added with lubricant;
(6) a large amount of raw materials of disposable syringe consumption, produce a large amount of hospital refuse;
(7) make up a prescription in process and produce a large amount of microgranules, sufferer is caused to health threat.
Wherein, main species and the production process of the microgranule in process that makes up a prescription have: one, plastic particles, transfusion bag adsorbate in process of production; Two, rubber particle produces in the time of needle for inserting bottle puncture plug; Three, fiber, batting, dust particle contacts generation during opening bag and puncturing with indoor environment; Four, carbon black particle, the microgranule that some pharmaceutical preparatioies itself exist; Five, insoluble micelle due to the restriction of purifying technique, produces in Chinese herbal and crude drugs preparations production process; Six, crystalline solid microgranule, changes and increase memory time in the situation that produces in medicament storage condition; Seven, glass chip microgranule, the microgranule being scattered while being cutting ampoule; Eight, drug microparticles, adds when medicine, because some powder dissolve not exclusively, between medicine, physical and chemical effect, solvent change, pH value variation etc. occurs and produces.Above-mentioned various microgranule causes health threat to sufferer.
