Femoral artery intubation and indwelling catheter perfusion method capable of monitoring and increasing blood supply to lower limbs

Abstract

The invention relates to a femoral artery intubation and indwelling catheter perfusion method capable of monitoring and increasing blood supply to lower limbs, and relates to the technical field of medical supplies. The femoral artery intubation comprises an intubation main body and a puncture tube core, the two ends of the intubation main body are provided with openings, the intubation main body is provided with a hollow inner cavity, the puncture tube core is provided with a conical tip, and a perfusion pipeline used for monitoring and increasing blood supply to the lower limb is arranged in the intubation main body, the perfusion pipeline is opened in the middle of the intubation main body, a monitoring pipe is arranged one end, entending to the outside of the intubation main body, of the perfusion pipeline, and the indwelling catheter perfusion mode is also provided. According to the femoral artery intubation and indwelling catheter perfusion method capable of monitoring and increasing blood supply to the lower limbs, the femoral artery intubation and indwelling catheter perfusion method capable of monitoring and increasing blood supply to the lower limbs is different from manual observation of medical staff, the timeliness is good, lower limb ischemia complications can be recognized as soon as possible, data is provided for related scientific research of lower limb ischemia, the application prospect is good. Different from the mode that a lower limb far-end perfusion tube is punctured again to increase lower limb blood supply, the puncture frequency and puncture injury can be reduced, the occurrence rate of vascular complications is reduced and the pain of a patient is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a femoral artery catheterization and catheter perfusion method capable of monitoring and increasing the blood supply of lower extremities. Background technique [0002] The basic modes of ECMO operation include VA-ECMO and VV-ECMO. The principle of VA-EVMO is to draw venous blood through venous catheterization, undergo membrane oxygenation and remove carbon dioxide, turn venous blood into arterial blood, and then insert it through the artery. The tube returns to the arterial system. Due to the superficial position of the femoral artery and the simple anatomical structure, the femoral artery is often used as the return vessel for VA-ECMO; [0003] Since the femoral artery cannulation blocks the blood perfusion of the distal lower limbs, it may lead to lower limb ischemia and affect the prognosis of patients. This has become one of the more common complications...

AI Technical Summary

Problems solved by technology

[0003] Since the femoral artery cannulation blocks the blood perfusion of the distal lower limbs, it may lead to lower limb ischemia and affect the prognosis of patients. This has become one of the more common complications of VA-ECMO, and the monitoring of lower limb ischemia is mainly performed by medical staff. Observe whether the lower limbs have pale skin, coolness, fixed joints, increased muscle tension, etc., but once it is found, it is a serious deficiency and the timeliness is poor. The common solution in clinical practice is to go through the blood flow direction again and again Puncture into a separate perfusion tube at the distal end of the lower extremity, the operation is complicated, the puncture injury of the femoral artery is increased, and there is a possibility of increasing vascular complications, which further causes pain to the patient;
