PICC duct outer fixing sleeve

Abstract

The invention discloses a PICC duct outer fixing sleeve. The PICC duct outer fixing sleeve includes an inner belt and an outer belt; a groove opening running through the inner and outer side faces ofthe inner belt is formed in one end of the inner belt, primary snap fastener pieces are arranged at the end, away from the groove opening, of the inner side face of the inner belt, and a plurality ofgroups of secondary snap fastener pieces capable of fastening with the primary snap fastener pieces are arranged on the outer side surface of the inner belt; the inner belt is further provided with vent holes; the outer belt is used for coating the inner belt and includes an outer main body and connection belts, wherein the connection belts are arranged at two ends of the outer main body, and faces, capable of cooperating with each other, of a second hook-and-loop fastener are arranged on the inner side surfaces of the connection belts and the outer side surface of the outer main body respectively; and faces, capable of cooperating with each other, of a first hook-and-loop fastener are arranged on the outer side face of the inner belt and the inner side face of the outer main body respectively. By adopting the PICC duct outer fixing sleeve, problems such as infection on patient skin caused by using tape for fixing can be avoided; the PICC duct outer fixing sleeve has good breathability, can improve comfort of punctured parts of a patient and reduce the possibility of infecting or crushing the punctured parts, and is conducive to prolonging the service life of a PICC duct.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a PICC catheter external fixing sleeve. Background technique [0002] The PICC tube is a central venous catheter placed through peripheral venipuncture. It uses a catheter to puncture the vein of the peripheral arm. The catheter goes directly to the large vein near the heart to avoid direct contact between chemotherapy drugs and the vein of the arm. In addition, the blood flow speed of the large vein is very high. Fast, it can quickly dilute the chemotherapy drugs and prevent the drugs from stimulating the blood vessels, so it can effectively protect the upper limb veins, reduce the occurrence of phlebitis, relieve the pain of patients, and improve the quality of life of patients. [0003] Under normal circumstances, the existing PICC tube can be used continuously for one year or more, but during use, the arm cannot move too much or too vigorously to prevent the catheter from fa...

AI Technical Summary

Problems solved by technology

[0004] Traditional fixation of PICC tubes mainly relies on the method of tape wrapping. This method can fix the outside of PICC tubes well, but after a long time, it is easy to affect the skin at the puncture site, and even cause inflammation and infection of the skin or veins. The consequences are relatively Serious, and the tape is fixed, the shape is not good, and the function is relatively simple, which seriously affects the comfort of the patient
