Vibration-crushing micro-pill machine

The invention pertains to the technical field of medicine preparation and relates to a vibration-crushing micro-pill machine which comprises a liquid storage pot, a pill dripping system, a cooling circulation device, a micro-pill collecting machine and a control circuit, wherein the pill dripping system comprises a dropper, a jet hole, a vibration exciter and a gear pump. The dropper is connectedwith the vibration exciter by a rigid connecting rod. The lower part of the dropper is provided with one or more jet holes, the upper part of which is a liquid inlet and the lower part thereof is a nozzle. The dropper is connected with an electric valve at the lower part of the liquid storage pot by pipes on which the gear pump is arranged. The side wall of the dropper is provided with two insertion holes in which a heater and a temperature sensor respectively connected with the control circuit are arranged. The control circuit controls the make-and-break of the heater according to the detected temperature of the temperature sensor. The cooling circulation device comprises a condensation column, a stirring device, a filter, a cooling cylinder, a cooling pump and an electromagnetic pump. The vibration-crushing micro-pill machine has the advantages of chance of batch production of micro-pills, high production efficiency, simple equipment structure and convenient control.

Method using 3D printing technology to prepare dropping pills

The invention relates to a method using the 3D printing technology to prepare dropping pills. The method using the 3D printing technology to prepare the dropping pills comprises the steps of (1) using polyethylene glycol and the like as base materials, carrying out heating melting, (2) adding prescription drugs at the specified temperature, carrying out mixing, even stir and freeze drying to obtain solid powder, carrying out sieving on the solid powder, and (3) placing the solid powder into a powder box of a 3D printer, and preparing the dropping pills through electronic drafting, remote data transmission and laser scanning printing. According to the method using the 3D printing technology to prepare the dropping pills, due to the facts that through a series of technologies such as the electronic design technology, the remote data transmission technology, the laser scanning technology and the raw material and auxiliary material melting technology, the specific drug powder materials are melted, and electronic model graphs are changed into the real dropping pills according to designed indications, the advantages of the dropping method of preparing the dropping pills are kept, and the defects that due to the influence of the factors such as physical properties of liquid medicine, droppers and cooling liquid, pill weights are different, the roundness of pills is difficult to control, the percent of pass is low, and specially-shaped dropping pills cannot be easily prepared when the dropping method is used for preparation are overcome.

Preparation method for condensed pill of traditional Chinese medicines

The invention belongs to the field of medicine preparation, and particularly discloses a preparation method for a condensed pill of traditional Chinese medicines. The preparation method comprises thefollowing steps: preparing particles from a part of a medicinal material extract and fine medicinal material powder, carrying out pressing to from a pill mold, adopting the pill mold as a base pill, and rounding the remaining prescription amounts of the medicinal material extract and the fine medicinal material powder and a proper amount of an excipient to form the pill. According to the preparation method disclosed by the invention, effective components can be reserved to the greatest extent; the preparation method well solves problems in proportioning stability of the extract and the medicinal powder; prepared condensed pills are small in pill weight difference, accurate in dosage, shortened in dissolution and dispersion time limit, good in absorption, stable and controllable in qualityand improved in curative effect; a production period is shortened; process is simple; a production environmental is good in sanitation condition; labor intensity is reduced; various quality indexes are obviously improved; and good social and economic benefits are obtained.

Mirabilitum praeparatum throat-soothing dropping pill and preparation method thereof

The invention relates to a traditional Chinese medicine formulation mirabilitum praeparatum throat-soothing dropping pill and a preparation method thereof. The traditional Chinese medicine formulation mirabilitum praeparatum throat-soothing dropping pill comprises the following active pharmaceutical components in parts by weight: 20-80 parts of mirabilitum praeparatum, 0.5-5 parts of borneol, 1-5 parts of dementholized peppermint oil and 1-6 parts of menthol; an auxiliary material comprises the following components in parts by weight: 100-350 parts of polyethylene glycol-4000 and 1-6 parts of steviosin. The invention also relates to the preparation method of the mirabilitum praeparatum throat-soothing dropping pill. The mirabilitum praeparatum throat-soothing dropping pill disclosed by the invention is relatively high in heat stability by selecting the steviosin as a flavoring agent, and can not be decomposed by being heated for a long time, thereby solving the problem of instable heat of aspartame in the prior art; meanwhile, the preparation method disclosed by the invention solves the problem that a dropper is easy to adhere in a dropping process by regulating the matrix ratio, therefore, the preparation process is more suitable for large-scale industrialized production and ensures the smoothness of a production process.
