Improved ear-hanging fixing device for temporary pipelines in hemodialysis

Abstract

The invention discloses an improved ear-hanging fixing device for temporary pipelines in hemodialysis. The improved ear-hanging fixing device of the present invention comprises an adjusting mechanismI. Both sides of the adjusting mechanism I are provided with connecting rods. One ends of the connecting rods, far away from the adjusting mechanism I are provided with adjusting mechanisms II. The tops of the adjusting mechanisms II are provided with ear hooks. The front surface of the right adjusting mechanism II is provided with an adjusting mechanism III. During wear, locking bolts are loosened according to neck size of a patient, so that a sliding rod slides in an inner cavity of a sliding tube for size adjustment until the wearing requirements of the patient are met. Meanwhile, the damped rotation of a rotating block in an inner cavity of a fixing frame also ensures the stability during wearing. Because the adjustment mechanism I, the adjustment mechanisms II, the adjustment mechanism III and the adjusting mechanism IV can be locked and fixed after the adjustment is completed, the stability during wearing is also improved, thereby facilitating use of users and wearing of patients, and reducing troubles of medical staff.

Description

technical field [0001] The invention relates to the technical field of hemodialysis, in particular to an improved hemodialysis temporary pipeline ear-mounted fixing device. Background technique [0002] Hemodialysis is one of the renal replacement therapy methods for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. ) inside and outside each hollow fiber, through diffusion / convection for material exchange, remove metabolic waste in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and return the purified blood to the whole process. For hemodialysis. [0003] In the treatment of hemodialysis, long-term tubes and temporary tubes may be used, and long-term tubes are convenient because they are used for a long time, and are not easy to be infected. Temporary tubes are used for a short time and may be ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an improved hemodialysis temporary pipeline ear-mounted fixing device, which has the advantages of being able to adjust the size according to the patient's use requirements and improving the wearing stability, and solves the possible problems in the treatment of hemodialysis. Long-term tubes and temporary tubes are used, and long-term tubes are convenient because they are used for a long time, and they are not easy to be infected. Tubes are inserted from the carotid artery, and after insertion, the temporary tube needs to be stabilized to ensure the normal operation of hemodialysis, and the traditional device for fixing the temporary tube cannot be adjusted according to the patient's neck. The size of the neck can be adjusted, and its fixing method is generally set on the patient's neck, which has poor stability, and because its size cannot be adjusted, and when the patient's neck size is large, it is not easy to wear, which is a medical The work of personnel causes trouble, and it cannot meet the needs of patients
