Description

An automatic drug-taking mechanism for an injection intelligent medicine cabinet

technical field

The invention belongs to the field of medicine dispensing mechanisms of intelligent medicine cabinets, and in particular relates to an automatic medicine taking mechanism of intelligent medicine cabinets for injections.

Background technique

The current automated pharmacy realizes the functions of large-scale storage and fast and accurate drug delivery, which greatly reduces the workload of finding medicine in the pharmacy, but it still depends on manual labor to deliver the medicine from the pharmacy to the ward. Therefore, the workload of this part has not been reduced. In addition, the current automated pharmacies mainly target boxed medicines, but there are relatively few researches on automated equipment for storage of injection medicines. For the storage of injection medicines, the trough-type automated pharmacy can store, but one box of medicines is output at a time. Medicines are wasted when the demand is small. In addition, the carousel-type automated pharmacy can also store injection medicines, but it cannot achieve single-bottle output. Because injection medicines have the characteristics of large difference in shape and size and fragility, there is currently no equipment for storage and single-bottle output of injection medicines. In addition, the existing automated pharmacies often collide and squeeze the medicines during the dispensing process, so they cannot be used for the storage of medicines with special requirements in this regard. At present, medical staff in ordinary hospitals have to take injections and medicines back and forth between the ward and the pharmacy, which is labor-intensive and inefficient. It is necessary to develop an automated device that can store injections and medicines and output them in a single bottle.

In the prior art, the medicine dispensing mechanism of the intelligent medicine cabinet for injection mainly uses a graduation plate to divide the medicine. There must be a separate driving part, and the cost is relatively high.

In view of this, the present invention provides an automatic drug-taking mechanism of an injection smart medicine cabinet with a simple structure and low cost, which can accurately dispense glass bottled injection drugs according to the requirements of the drug list.
