Femoral artery catheter fixing device

Abstract

The invention discloses a femoral artery catheter fixing device. The femoral artery catheter fixing device comprises a storage fixing seat, a latex pad is arranged on the lower surface of the storage fixing seat, a fixing mechanism is arranged on the upper surface of the storage fixing seat and composed of transverse hasps and longitudinal hasps, an outer side connecting mechanism is arranged on the outer side of the storage fixing seat, and the outer side connecting mechanism is composed of a first bandage, a magic tape face A, a second bandage and a magic tape face B. According to the femoral artery catheter fixing device, the fixing mechanism, the latex pad, a pressure sensor, an adjustable hasp and a telescopic connecting pipe are arranged, a catheter can be fixed through the fixing mechanism, the probability that the catheter falls off, is broken and is bent is reduced, the latex pad separates the skin from the catheter, pressure damage to the skin is reduced, skin damage is avoided, use is safe, the pressure sensor dynamically pays attention to the femoral artery pressure of a patient, a basis is provided for selecting a proper infusion device, and the comfort of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a femoral artery catheter fixing device. Background technique [0002] Hepatic arterial infusion chemotherapy has been used in patients with advanced hepatic malignancies and has been shown to have favorable response rates and survival benefits. The Guidelines for the Diagnosis and Treatment of Primary Liver Cancer (2019 Edition) also pointed out that for some patients with hepatic malignant tumors, HAIC treatment method can be used as appropriate when the effect of transarterial chemoembolization is not good, because of its repeatability, precision and safety. It is recommended by the Japanese liver cancer guidelines as the standard treatment for liver cancer with portal vein tumor thrombus. HAIC is intubated from the femoral artery, and the end of the cannula is connected to the blood supply artery of the liver tumor, and the chemotherapy drugs are perfused...

AI Technical Summary

Problems solved by technology

The following problems occurred in the clinical implementation process: 1. The exposed femoral artery tube (including vascular sheath, catheter and microcatheter) is about 60cm long and needs to be fixed at the root of the thigh. At present, there is no device to fix the exposed catheter in clinical practice. , distorted, or even detachment, the medical staff need to spend a lot of time to wrap the exposed catheter with multiple layers of gauze, and then fix it with a bandage; Cause pressure injury, redness or even damage; 3. The common complication of femoral artery puncture is bleeding at the puncture point. At present, catheter fixation needs to be covered with multiple layers of gauze, which is not conducive to the observation of bleeding and has potential safety hazards; 4. At present, femoral artery Invasive blood pressure measurement in the local area requires a pressure sensor connected to a connecting tube, and then an external monitor to complete the process, which is complicated; 5. It takes a long time for medical staff to complete this operation; 6. Patients stay in bed for a long time, and their comfort level decreases
