Internal arteriovenous fistula puncture protection and heat preservation device

Abstract

The invention discloses an internal arteriovenous fistula puncture protection and heat preservation device, and relates to the technical field of medical instruments. The internal arteriovenous fistula puncture protection and heat preservation device comprises a lower sleeve, the top of the lower sleeve is fixedly connected with an elastic band, the top of the elastic band is fixedly connected with an upper sleeve, and the side, away from the elastic band, of the upper sleeve is fixedly connected with a first hook-and-loop fastener. The internal arteriovenous fistula puncture protection and heat preservation device has the beneficial effects that through the arrangement of the lower sleeve and the upper sleeve, a nurse moves the arm of a patient into the lower sleeve, the lower portion ofthe arm makes contact with a first base layer, then the nurse rotates the upper sleeve to reset the upper sleeve, then the first hook-and-loop fastener and a second hook-and-loop fastener are stuck again, so that the lower sleeve and the upper sleeve are closed, use by the patient is facilitated, the arm of the patient cannot touch an internal fistula limb when the arm is taken out of the lower sleeve and the upper sleeve, and the device is better in safety.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an arteriovenous fistula puncture protection and heat preservation device. Background technique [0002] Arteriovenous fistula is to artificially establish a short circuit between an artery and a vein through surgery, so that patients on hemodialysis can effectively perform extracorporeal circulation. Under normal circumstances, our most common arteriovenous puncture is the anastomosis between the distal radial artery and the cephalic vein. This is our preferred long-term vascular access, but if no suitable blood vessels can be found in both forearms, we can Using a replacement vessel, a fistula of the grafted vessel is established. Generally, the commonly used transplanted blood vessels mainly include autologous blood vessels and artificial blood vessels. During hemodialysis internal fistula puncture, frequent punctures are required, but due to the natural contracti...

AI Technical Summary

Problems solved by technology

During hemodialysis internal fistula puncture, frequent puncture is required, but due to the natural contraction of blood vessels with temperature changes, especially in cold winter, the difficulty of puncture and the pain of patients will increase

In addition, the temperature of the hemodialysis room drops in winter, and the exposed part of the arm will make the patient feel obvious discomfort during the dialysis process. If it is covered with a quilt, it will easily cause safety accidents

The existing arteriovenous fistula puncture protection and heat preservation device is inconvenient to use, and the device cannot be conveniently fixed or removed from the patient's arm, and at the same time, it is easy to touch the fistula limb, causing damage to the fistula limb , In addition, medical staff need to observe the condition of the internal fistula operation limb in real time during treatment, and the existing internal fistula care products are inconvenient to observe
