Automatic medicine taking device
Technical Field
The invention belongs to the field of dispensing systems, and particularly relates to an automatic medicine taking device.
Background
When a medicine feeding and quantifying device of an intelligent traditional Chinese medicine dispensing machine is researched, a design scheme is changed for a plurality of times through research, a spiral medicine feeding mode is tried at first, although the spiral medicine feeding mode basically realizes the functions of active medicine feeding and accurate medicine measurement, under the repeated test, because the traditional Chinese medicine particles are required to be continuously added into a medicine storage bottle along with the use of the medicine, the situation that no air enters is difficult to be ensured in the adding process. Once air enters the medicine storage bottle, the medicine is easily hardened after long-term use, and the medicine feeding efficiency is affected. On the other hand, in the spiral medicine feeding mode, only one of a pair of traditional Chinese medicines can be sent at a time, and a patient generally cannot buy only one pair of traditional Chinese medicines at a time, so that the efficiency is low, meanwhile, after the spiral medicine feeding device is used for a long time, traditional Chinese medicine particles are attached to a medicine storage bottle and a stirrer, the cleaning is difficult, the mildew is easy to occur, and the quality of medicines is influenced, so that how to design an automatic medicine taking device which can reduce the contact chance between the medicines and air as much as possible and match multiple medicines simultaneously becomes a subject of research of technicians in the field.
