Description

An insulin pump infusion trocar

technical field

The utility model relates to an insulin pump infusion trocar, which relates to an infusion trocar used together with an insulin pump and capable of regularly and quantitatively injecting insulin into a human body.

Background technique

At present, insulin pumps and disposable insulin pump infusion components are relatively new medical devices in the medical field. This is a new way to treat diabetes. Its main function is to infuse a small amount of insulin into the patient's body every short period of time by artificially setting the infusion volume of the insulin pump, so as to achieve a good control of the patient's blood sugar, so as to relieve the pain of high blood sugar and the complications caused by diabetes. Existing imported and domestic insulin pumps are generally composed of a pump body, a disposable delivery catheter, a drug storage device, a propulsion mechanism and related infusion components. Due to the infusion needle and catheter of the existing infusion components, the installation is not convenient enough. , It is easy to cause quality problems such as leakage, which brings inconvenience to patients and affects the therapeutic effect.

Contents of the invention

The purpose of this utility model is to provide an insulin pump infusion trocar for the above shortcomings, which can be used with an insulin pump to effectively treat patients according to the dose set by the insulin pump. It is easy to install and use, safe, reliable, and reliable. The leaked injection can be easily connected and separated from the insulin pump, which can effectively control the patient's blood sugar and achieve the expected therapeutic effect.

An insulin pump infusion trocar is realized by adopting the following scheme: an insulin pump infusion trocar is composed of a needle seat, a non-woven fabric with adhesive, and a curved needle. The needle seat is installed on the adhesive non-woven fabric, and the needle seat is equipped with a curved needle. The needle seat is exposed at both ends of the looper. An infusion catheter installation hole is arranged on one side of the needle seat, and the infusion catheter is inserted into the installation hole. One end of the looper is covered with a sheath to form a trocar, and the other end of the looper is inserted into the infusion catheter.

The looper is a 70-110° looper.

Described looper adopts 90 ° looper.

The infusion catheter is made of polyethylene (PE) material and has certain elasticity and hardness.

working principle :

   First install the liquid aspiration needle on the outer conical locking joint at the front end of the drug storage cylinder, pull the core rod, drive the piston to extract the insulin liquid, pump the liquid into the drug storage barrel, and then remove the liquid aspiration needle and the core rod . Then install the drug storage device in the drug storage compartment of the insulin pump, and at the same time, the drug injection push rod is connected with the piston in the drug storage cylinder with threads, and then the conical joint is installed on the front end of the drug storage cylinder. On the collar and the outer conical locking joint, assemble the male connector and the female connector of the infusion line separator, then hang the insulin pump on the waist of the patient, and insert the trocar into the patient's abdomen subcutaneously. Turn on the DC motor of the insulin pump, push the injection push rod through the reducer, and the piston at one end of the injection push rod advances along the inner cavity of the drug storage cylinder, and the insulin liquid in the drug storage cylinder passes through the front end of the drug storage cylinder. The conical joint, infusion catheter, infusion line separator, infusion catheter and the curved needle in the trocar are injected into the subcutaneous skin of the human abdomen, and the adhesive non-woven fabric is pasted on the injection site of the human abdomen.

When the patient needs to take the insulin pump out of the body, the male and female connectors in the infusion line separator can be rotated 90° to separate them, so that the insulin pump can be removed from the patient and bent Needles, infusion catheters, adhesive non-woven fabrics and male connectors can remain on the human body for easy use by patients. Since the front end of the male connector is equipped with a silicone sealing plug to prevent contamination.

An insulin pump infusion cannula features:

1. The shape of the needle seat of the utility model is very suitable for piercing the human body with a curved needle, and fits well with the human body. Since the part of the curved needle entering the human body is small, it will not bring pain and discomfort to the patient during puncturing and infusion.

2. When the patient needs to separate the insulin pump from the body, the male and female connectors in the infusion line separator can be rotated to separate them. Therefore, the insulin pump is removed from the patient, and the curved needle, the infusion catheter, the adhesive non-woven fabric and the convex connector can be left on the human body, which is convenient for the life of the patient.

3. Since the material of the infusion catheter is polyethylene (PE), it will not react with the insulin solution and prevent its deterioration. The infusion catheter has a certain degree of elasticity and hardness, which can prevent it from being squeezed and deformed during infusion and blocked.
