The present invention relates to a powder allotting device, and more particularly to an automatically powder allotting device.
With progress of modern-medicine technology and concept, medical centers now provide Chinese herb with pills, capsules, or medical powders for patients instead of bags of Chinese herbs.
Recently medical powders being used by most of medical units are processed powders, wherein these medical powders are placed into convenient pots, thereby medical staffs allot different amounts of medical powders for different patients with various diseases. However, conventional medical powder allotting device is not very precise for allocating medical powders, because it is still necessary for medical staffs to allocate amounts of medical powders by personal experience and sense.
After medical powder packing device allocates medical powders, it may still remain some surplus powders. Thereafter, these surplus medicines may drop into following medicines to different disease that could lead to unpredictable results for next patient. However, the surplus powders only can be cleared or collected by some tools such as brush or dust cleaner. Additionally, these cleared or collected powders would merely be dumped, and that may cause higher cost and waste issue.
The conventional medical powder allotting devices substantially include an allocating device and a packing device, as disclosed in TW Pat. No. I247604. Referring to
According to foresaid prior art, the medical powders need to be scraped flat or allocated equally by artificiality. However, the medical powders are allocated or scraped flat only rely on personal experience or sense of medical staffs, whereby allocation of the medical powders is not very precise. Hence, the conventional medical powder still lacks a complete technology for equally allocating medical powders.
Moreover, as medical powders are allocated into an allocating device, there may remain some surplus medical powders thereof that may lead to a lot of unpredictable results. For avoiding these unpredictable results, medical staffs need to implement extra clear action after allocated medical powders. However, it may cause medical cost up that the extra clear action need extra expending of human resource, cost, and medical powders
