Multifunctional autologous internal arteriovenous fistula limb fixing and protecting device for hemodialysis patient

Abstract

The invention discloses a multifunctional autologous internal arteriovenous fistula limb fixing and protecting device for a hemodialysis patient, which comprises a limb fixing assembly including a base and an arm fixing part arranged on the base; a rotating clamping assembly comprising a clamping assembly and a rotating assembly, wherein the rotating assembly comprises a vertical rod, a movable joint, a transverse rod and a magnetic attraction piece arranged at the other end of the transverse rod; a clamping assembly clamped on a bed frame, wherein the vertical rod and the clamping assembly are integrally connected, and the transverse rod and the bottom end of the base are movably connected in a clamped mode through a magnetic attraction piece; and a control assembly comprising a control box, wherein a warm air assembly, an inflation assembly, a microprocessor, a control button and a power supply assembly are arranged in the control box; The device has the characteristics of fixing the arm of a patient, monitoring blood leakage, warming and keeping warm, lifting the position according to conditions and being integrally fixed and stable, the pain of the patient can be effectively reduced, and the use safety of internal fistula and the comfort of the patient are improved.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to a multifunctional device for fixing and protecting the limbs of autogenous arteriovenous fistulas of hemodialysis patients. Background technique [0002] Hemodialysis is one of the main methods to treat chronic renal insufficiency. The prerequisite for treatment is to have a reliable vascular access, which directly affects the patient's dialysis and survival. Domestic and foreign studies have shown that vascular access has become the number one reason for hospitalization of maintenance dialysis patients and is the main factor causing medical expenses. Autogenous arteriovenous fistula is the most ideal vascular access for hemodialysis patients, and is called the "lifeline" of dialysis patients. A long-term use, unblocked and well-functioning arteriovenous fistula can not only solve the unnecessary pain and treatment costs caused by repeated fistula operations, but also satisfy hemodia...

AI Technical Summary

Problems solved by technology

[0004] 1) Poor hand fixation;

[0005] Since one dialysis treatment takes 4 to 4.5 hours, the patient cannot stay in one posture for a long time due to the long dialysis treatment time, and often causes bleeding or hematoma at the puncture site of the arteriovenous fistula due to physical activities, and even the puncture needle slips off;

[0006] 2) During the dialysis process, it is necessary to closely observe whether there is any abnormality such as blood leakage and bleeding at the puncture point of the patient. At present, the nursing staff can only rely on artificial observation at all times. Sometimes the medical staff is busy with other patients and fails to detect the bleeding and bleeding in time

It will cause bleeding or even slippage of the puncture needle;

[0007] 3) After arteriovenous fistulaplasty, swelling of the limb on the side of the fistula is due to the obstruction of venous return due to the lack of establishment of the corresponding collateral circulation after the vein is cut off. At the same time, avoid weight-bearing or pressure on the limbs on the fistula side; currently, pillows are used to achieve the purpose of cushioning, which has poor stability and is prone to displacement;

[0008] 4) At present, there is a simple U-shaped fixing pad, which has poor fixation. When the patient suddenly lifts up after waking up, the fixing pad is also taken up together so that the effect of fixing the arm cannot be achieved;

[0009] 5) When patients undergo hemodialysis treatment, their limbs should be exposed for easy observation. In winter, the blood vessels will constrict after being cold, which will cause insufficient blood flow and discomfort caused by the patient's limbs being cold;
