Hematodialysis upper limb internal fistula supporting and improving device

Abstract

The invention discloses a hematodialysis upper limb internal fistula supporting and improving device. According to the technical scheme, the hematodialysis upper limb internal fistula supporting and improving device comprises a fixing mechanism and a temperature control mechanism, wherein the temperature control mechanism is connected with the fixing mechanism; the temperature control mechanism comprises a shell, an air blower, an ultrasonic probe and a controller; the fixing mechanism comprises a bottom plate and a binding band; the binding band is connected with the bottom plate; the shell is connected with the bottom plate; the air blower is positioned on a side surface of the shell and communicates with a cavity of the shell with the outside; a heater is placed in the air blower; the controller is positioned in the shell and is electrically connected with the air blower, the heater and the ultrasonic probe separately; an arm of a patient is fixed on the bottom plate through the shell and the binding band; and the ultrasonic probe is in contact with the skin of the upper surface of an arteriovenous internal fistula on the arm, the ultrasonic probe monitors blood flow to controlthe air blower and the heater to change the temperature of the outside of the arm, thus, the blood flow maintains in a normal state, and the problem that in an arteriovenous internal fistula surgery,blood voltage is not stable is solved.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for improving hemodialysis upper limb flaccidity support. Background technique [0002] Hemodialysis is the most effective treatment for patients with chronic renal failure and acute drug poisoning. Arteriovenous fistula is one of the surgical procedures, mainly used for hemodialysis treatment. Arteriovenous fistula is a small operation of vascular anastomosis. The artery near the wrist of the forearm is sutured to the adjacent vein, so that arterial blood flows in the vein after the anastomosis, forming an arteriovenous fistula. The blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment, and provide sufficient blood for dialysis. Adequacy of treatment is guaranteed. [0003] During the impotence operation, the patient cannot change the position at will, and the dialysis time is long, the blood pressure and blood flow will not always remain...

AI Technical Summary

Problems solved by technology

[0003] During the impotence operation, the patient cannot change the position at will, and the dialysis time is long, the blood pressure and blood flow will not always remain unchanged, and the patient may cause blood pressure and blood flow in the arteries and veins due to sleep or involuntary activities, etc. Changes in blood flow make the effect of blood flow between arteries and veins worse, reduce the therapeutic effect of arteriovenous fistula surgery, and even cause arteriovenous fistula surgery to fail, which not only increases the workload of doctors, but also imposes a burden on patients. bring financial and physical burden
