PICC (peripherally inserted central catheter) puncture fixation method

Abstract

A fixing method for PICC puncture. Input the desired pressure value through the remote control and start it. The wireless transmitting part on the remote control transmits the signal to the wireless transmission module. The microprocessor controls the pressure adjustment device to the adjustable Inflate the inflatable cushion. When the preset pressure value is reached, the pressurization is stopped and the pressure is kept stable at the preset value. After routine disinfection, the venipuncture of the catheter can be performed. The human body surface picks up signals to detect heart rate and blood pressure. The present invention can be directly placed on the upper arm, without the need for medical staff to keep watch during the puncture process, and has a larger contact area with the arm, combined with the pressure sensor, it can accurately sense the pressure on the arm, and the blood vessels burst when the pressure is adjusted to a suitable pressure There will be no sliding and shifting after the operation, and the medical staff can see the patient's blood pressure and heart rate information in real time and take timely measures to ensure the smooth progress of the puncture process.

Description

technical field [0001] The invention relates to a fixing method for PICC puncture. Background technique [0002] Central venous catheterization through peripheral venous puncture is to use a catheter to puncture from the vein of the peripheral arm. The catheter goes directly to the large vein close to the heart, which can avoid direct contact between chemotherapy drugs and the arm vein, and the blood flow of the large vein is very fast, which can Rapidly dilute chemotherapy drugs to prevent drugs from stimulating blood vessels, so it can effectively protect the veins of the upper limbs, reduce the occurrence of phlebitis, relieve pain of patients, and improve the quality of life of patients. The current puncture method is to first measure the length of the patient from the puncture site to the superior vena cava with a tape measure. After selecting the puncture site at the elbow, tie a venous tourniquet. After routine disinfection, venipuncture of the catheter is performed, ...

AI Technical Summary

Problems solved by technology

In practical application, it is found that some elderly patients are thin and have very thin blood vessels. After the ordinary venous tourniquet is tied on the upper arm of the patient, it is difficult to find the position of the needle, and multiple punctures are required, which increases the pain of the patient; On the one hand, the puncture process requires relatively high technical requirements for the operation. The patient's blood vessels are easy to slip during the puncture process using a common tourniquet, and it takes repeated punctures to succeed, which brings great pain to the patient.
