Fistula protecting device for hemodialysis patients

Abstract

The invention discloses a fistula protecting device for hemodialysis patients, and relates to the technical field of medical auxiliary instruments. The fistula protecting device comprises a fistula protecting device body; the fistula protecting device body comprises an outer shell and a base; the outer shell is made of PVC hard plastic of a U-shaped structure; an opening is formed in one side of the outer shell; a sliding groove is formed in the position, close to the opening, of the top of the outer shell; a fixing frame is arranged in the sliding groove in a penetrating mode; a handle is arranged at the top of the fixing frame; an arm shield is arranged at the bottom of the fixing frame; a fastening piece is arranged between the outer shell and the fixing frame; a ventilation groove is formed in the upper portion of the interior of the outer shell; an infrared lamp is arranged at the bottom of the ventilation groove; an arm support is arranged at the bottom in the outer shell; and the arm support is hinged to the inner wall of the outer shell. According to the beneficial effects, the arm of a patient can be effectively fixed and protected; when the air temperature is relatively low, the arm of the patient can be irradiated and baked through the infrared lamp; and a good ventilation facility is provided, the placing angle of the arm can be adjusted inside, and the device is simple, practical, humanized in design and capable of being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a fistula protection device for hemodialysis patients. Background technique [0002] "As we all know, 365 days a year, the patient needs to undergo hemodialysis 3 times a week, leaving 2 needle holes for one dialysis, and 156 punctures for 52 weeks a year, leaving 312 needle holes, so the maintenance and puncture of the internal fistula can be done One can imagine how important it is. Hemodialysis is one of the main treatment measures for chronic renal failure at present. During hemodialysis, it is necessary to drain the blood in the human body into an artificial kidney device outside the body to achieve the purpose of dialysis. Establishing a good vascular access is The primary condition for the smooth implementation of long-term maintenance hemodialysis has an important impact on the effect of dialysis and the long-term survival of patients.

AI Technical Summary

Problems solved by technology

During hemodialysis, a puncture needle is inserted in the arm, and the quilt cannot be covered, resulting in the exposed arm, which is easy to catch cold and causes the blood vessels to contract due to cold stimulation, which affects the blood flow; During dialysis, the arm on the puncture side is generally not fixed. When the patient's arm is shaking or moving, the internal fistula puncture tube used for hemodialysis is easily pulled, and in turn, the corresponding internal fistula puncture needle will be displaced. As a result, hematoma or puncture needle falls off, which increases the pain of the patient and the risk of blood loss; on the other hand, the patient's arm does not have a good protective device to protect it. If the corresponding internal fistula puncture needle is touched, the corresponding internal fistula puncture needle may puncture the patient's arteriovenous blood vessels and cause subcutaneous hematoma, which will also bring pain to the patient.
