Description

Insulin pen of safe type

Technical Field

The utility model belongs to the technical field of the medical equipment technique and specifically relates to an insulin pen of safe type.

Background

The insulin pen avoids the tedious process that the patient draws insulin in the insulin medicine bottle by using an injector, can avoid the embarrassment that the patient injects insulin in public places, and brings convenience for the patient with poor eyesight or even blindness to inject insulin. When the existing insulin pen is used for injection, after sufficient insulin dosage is checked and confirmed, a dosage adjusting knob is rotated to adjust the number of required injection units. If the injected insulin is a suspension, the insulin pen should be turned upside down 10 times or so until the drug solution becomes a uniform white suspension, in order to prevent the concentration of the drug solution from being non-uniform and causing poor blood sugar control. Fast acting insulin (such as norhalol), short acting insulin (such as norhalol R) and insulin glargine (lefluide) are clear solutions that can be directly injected. Partial insulin injection patients have time difference in compliance, the needle is pulled out immediately after RI finishes, the needle is not pulled out after the needle point stays for 10 seconds according to requirements, and the residual quantity of insulin in the pen cannot be clearly distinguished by old people of a few years, so that the RI injection dose is insufficient or the insulin is not injected on the day to influence the treatment effect, and an insulin pen with a prompt function is needed at present.
