Current pulse permeation based insulin pump and injection method

Abstract

The invention discloses a current pulse permeation based insulin pump and an injection method. The current pulse permeation based insulin pump comprises an insulin pump, wherein a waistband is arranged at one side of the insulin pump, a telescopic part is arranged at one end of the waistband and is connected with the other end of the waistband, a sling is connected with one side of the waistband,shoulder straps are correspondingly mounted at the two sides of the sling, one end of each shoulder strap is movably connected with one side of the sling through a snapping buckle, a pulse direct-current generator is mounted at the top of the insulin pump, a platinum electrode is electrically connected with one side of the pulse direct-current generator correspondingly, a fixing paster is arrangedat the outer periphery of the platinum electrode, a position recording device is mounted at one side of the waistband and comprises a mounting seat, a guiding groove is formed in the waistband, and the internal wall of the guiding groove is in sliding connection with the mounting seat. The current pulse permeation based insulin pump and the injection method have the characteristics that the rateof diffusion is high, and an optimal injection position is automatically judged.

Description

technical field [0001] The invention relates to the technical field of insulin subcutaneous injection, in particular to an insulin pump and an injection method based on current pulse penetration. Background technique [0002] An insulin pump is an intelligently controlled insulin delivery device. It inserts the guide needle into the patient's skin, and then the screw motor of the battery-driven insulin pump pushes the piston to infuse insulin into the body. When the patient uses it for himself, he usually injects it in the abdomen and thighs to achieve the purpose of controlling diabetes. [0003] At present, after insulin is injected into the human body, it will accumulate under the skin, and it will take a long time to diffuse before entering the blood. It may be caused by hypoglycemia due to the large amount of medication that reaches the standard, and it cannot be continuously and stably infused according to the needs of the body. The existing experimental results show t...

AI Technical Summary

Problems solved by technology

[0003] At present, after insulin is injected into the human body, it will accumulate under the skin, and it will take a long time to diffuse before entering the blood. It may be caused by hypoglycemia due to the large amount of medication that reaches the standard, and it cannot be continuously and stably infused according to the needs of the body. The existing experimental results show that pulse current It can effectively improve the transdermal diffusion efficiency of insulin (see the paper "Promoting Effect of Pulse Current on Transdermal Insulin Penetration"), but it has not been applied in insulin pumps yet;

[0004] In addition, patients generally select the injection site manually based on experience, which is prone to multiple injections of insulin in the same small area, and fat hyperplasia and subcutaneous induration are prone to occur after repeated injections for a long time
