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 percutaneous penetration of insulin"), 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

Embodiment
[0053] Embodiment: When using the insulin pump, first wear it on the body through the belt 11, then judge the most suitable injection position through the position recording device 2 and move the catheter to it, and the patient manually pinches the injection needle 45 to place it Insert it into the skin and fix it on the abdomen. At this time, the platinum electrode 32 is pasted on the skin next to it, and the pulse current output by the pulse direct current generator 3 is used to accelerate the diffusion of insulin.

The invention discloses an insulin pump and an injection method based on current pulse permeation. One end is connected, one side of the waist belt is connected with a strap, the two sides of the strap are correspondingly equipped with shoulder straps, one end of the shoulder strap is movably connected with one side of the strap through a buckle, and the top of the insulin pump is installed with a A pulsed direct current generator, one side of the pulsed direct current generator is electrically connected to a platinum electrode, the outer peripheral surface of the platinum electrode is provided with a fixed patch, and a position recording device is installed on one side of the belt, and the position recording The device includes a mounting seat, and a guiding groove is provided on the belt, and the inner wall of the guiding groove is slidingly connected with the mounting seat. The present invention has the characteristics of high diffusion rate and automatic judgment of the optimum injection position.
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...
