A special needle for insulin pump to prevent the needle from falling off

Abstract

The invention discloses a special insulin pump needle capable of preventing a needle head from getting fallen. The special insulin pump needle comprises an insulin pump, a catheter, a connecting softhose, a kneading handle, a threaded tube, an inner tube, a sealing gasket, a groove, a buffering sponge, an outer tube, a threaded block, a fixed seat, an infusion soft hose, a shell, a lithium battery, a humidity sensor, a cavity, a rotating shaft, sticky cloth, a liquid leakage sensor, an alarm light, a hard needle and a soft needle. The special insulin pump needle provided by the invention is reasonable in structure, novel in design, simple to operate and convenient to mount; by arranging the cavity, the shell, the soft needle, the hard needle and the rotating shaft, a patient can do selection conveniently in accordance with own demands; meanwhile, the soft needle and the hard needle are rotatably connected to the cavity, so that the soft needle and the hard needle can be conveniently placed and carried; and real-time monitoring can be implemented by virtue of the humidity sensor, the liquid leakage sensor, the lithium battery and the alarm light, so that influence of perspiration and needle falling to an infusion effect can be prevented.

Description

technical field [0001] The invention relates to a trocar, in particular to a special needle for an insulin pump that prevents the needle from falling off, and belongs to the technical field of medical devices. Background technique [0002] The insulin pump consists of a pump, a small syringe and an infusion tube connected to it. The small syringe can hold up to 3ml of insulin. After the syringe is loaded into the pump, the guide needle at the front end of the connected infusion tube is inserted into the patient's chest with a needle injector. Subcutaneous (normally the abdominal wall), and then the screw motor of the battery-driven insulin pump pushes the piston of the small syringe to infuse insulin into the body. Inject into the user's skin to keep blood sugar stable throughout the day to achieve the purpose of controlling diabetes. [0003] Existing insulin pumps are generally composed of a pump body, a delivery catheter, and a drug storage catheter. The delivery cathete...

AI Technical Summary

Problems solved by technology

[0003] Existing insulin pumps are generally composed of a pump body, a delivery catheter, and a drug storage catheter. The delivery catheter is generally fixedly connected to the needle, which is not easy to carry and use, and patients and medical staff cannot know in time whether they are sweating or the needle is falling off.

Insulin leakage is caused, and small needles are implanted under the skin. There are two types of needles: soft needles and hard needles. The patient feels uncomfortable when the hard needle is implanted, but there is no danger of the needle coming out. The patient feels comfortable with the soft needle, but there is The danger of needle breakage and prolapse, ordinary infusion needles are not easy to place, and patients cannot choose soft and hard needles according to their own needs, which brings inconvenience to patients and affects the treatment effect
