Abstract

The invention provides a double-membrane filter for medicine dispensing. The double-membrane filter comprises a filter body, two filtering membranes and two top filter covers, wherein the two storagetanks are formed in the filter body by encircling a base plate with a sidewall; the base plate has a first surface and a second surface and is provided with a first through hole and a second through hole, wherein the first through hole is located in the first surface and the second through hole is located in the second surface; the outer side of the sidewall is provided with a first insertion pipeand a second insertion pipe; the first insertion pipe is internally provided with a first insertion hole which is communicated with the first through hole; the second insertion pipe is internally provided with a second insertion hole which is communicated with the second through hole; a cover plate covers the filter and is provided with a circle of insertion boards; diversion holes are formed inthe insertion boards; the top filter covers cover the storage tanks and are located in the storage tanks; the diversion holes are communicated with the second through hole; and the filtering membranesare located between the base plate and top filter covers and completely covers the first surface, and the edges of the filtering membranes are arranged between and bonded with the second surface andthe insertion boards through pressing. Since the double-membrane filter is provided with the two filtering membranes, two filtering passages are formed, so filtering efficiency is improved, and medicine dispensing time is reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a double-membrane drug dispensing filter. Background technique [0002] In the traditional dispensing method of soft infusion bottles, the disposer generally uses a disposable dispenser to suck a small amount of liquid in the soft infusion bottle and inject it into the powder injection bottle. After the powder in the injection bottle is dissolved, it is pumped back into the disposable dispenser. , and finally inject the liquid medicine into the infusion bottle. In the above-mentioned dispensing method, the insoluble particles in the dissolved liquid medicine are directly injected into the infusion bottle without being filtered, and the liquid medicine is easy to be polluted, wasted, and complicated to operate during the preparation process. insufficient. [0003] For this reason, a dispensing filter has appeared in the industry, which can directly connect the powder i...
