Technical Field
The utility model belongs to the technical field of medical care instruments, and particularly relates to a transfemoral catheter fixing device.
Background
Transfemoral transfemorrhoea is a surgical procedure used in regional chemotherapy, selecting the femoral artery on the most strongly pulsating side as the vascular access. If the femoral artery beats equally in the two groins, the right femoral artery is typically selected. If the femoral artery was punctured within week l, the contralateral femoral artery is preferably used. The puncture point should be selected to be about 2cm below the transverse striation of the femoral artery and just below the pulsation of the femoral artery.
Too high a puncture point may cause the puncture needle to cross the abdominal invar ligament, making hemostasis difficult after surgery. If the puncture point is too low, the femoral artery enters the position of the muscle contraction tube deeply, the puncture is not easy to succeed, and the femoral artery branches, and the femoral vein runs below the femoral artery, so the arteriovenous fistula is easy to cause.
The general operation flow is as follows:
1. prepare for washing hands and wearing a mask.
2. The prepared medicine is carried to the bedside, the bed number, the name, the treatment items and the like are checked, and the aim and the method of femoral artery injection are explained for the patient or family members.
3. Assisting the patient to take the supine position, straightening the lower limbs and slightly extending and outward rotating.
4. Checking the package, validity period, etc. of the injector, checking again, and sterilizing the skin of the puncture site by conventional method.

After returning blood, the injector is fixed by the right hand, the piston is drawn by the left hand, and samples are collected according to requirements or connected with a blood transfusion device.
6. After blood drawing or transfusion, the needle is pulled out quickly, and the local part is pressed by 3-5 root tip poison cotton swabs or gauzes for more than 5 minutes.
7. Assisting the patient to take a comfortable lying position and tidying the articles.
8. Sterilizing and washing hands.
