FIELD OF THE INVENTION
The present disclosure relates to the technical field of auxiliary medical
equipment, in
particular to an automatic medicine distributor.
BACKGROUND ART
When a patient is hospitalized, the doctor will issue a prescription according
to the patient's
condition, and then the hospital's pharmacy nurse will dispense and mark the
medicine for
the patients in the hospital according to the prescriptions issued by the
doctors. After the
medicines are prepared, the medicine box containing the medicines will be
distributed to the
corresponding patient.
However, because the pharmacy nurse works a lot every day and the volume of
tablets is
small, when the dosage of tablets in the prescription is large, the dispenser
might easily count
the wrong number of tablets due to being too tired. In case of long-time work,
the situation
of mismatched tablets occurs from time to time.
In general, a small difference in the dosage of tablets used will not have a
significant impact
on the patient; but for some tablets, a small difference in the number of
tablets may lead to
a serious medical accident.
The inventor found in the research that the existing tablet distribution has
the following
shortcomings:
manual dispensing is easy to make mistakes.
