Definitions
- the present invention relates to an automatic insulin pump, and more particularly, to an automatic insulin pump, which can reduce load applied to a rotary shaft providing ahead power to a piston to thereby improve durability thereof.
- the glycosuria patient or a protector for the glycosuria patient injects insulin into the patient twice or three times a day.
- the amount of insulin needed for the patient varies according to time and patient' s body conditions. For example, more insulin needs to be injected during taking a meal tha ' n in normal times.
- the conventional method for manually injecting insulin has several disadvantages in that it is impossible to inject an exact amount of insulin to the patient, and in that the patient suffers from an inconvenience of going to a hospital to administer insulin more than insulin injected in normal times.
