Fixing equipment with blood care temperature control for hemodialysis

Abstract

The invention specifically relates to fixing equipment with blood care temperature control for hemodialysis, and belongs to the field of hemodialysis. The equipment includes an arm fixing sleeve equipped with a locking plate, and a supporting base is installed at the bottom of the arm fixing sleeve; the equipment further includes a thermostatic box, and the thermostatic box is installed on the armfixing sleeve located on the side of the supporting base; a pass-through hole passes through the thermostatic box; and a heating system and a heat preservation chamber communicating with each other are installed in the thermostatic box, a return pipe is installed in the heating system, two ends of the return pipe are respectively connected to a control valve A and a control valve B, wherein the interiors of the control valve A and the control valve B are provided with temperature sensors, and the heat preservation chamber sleeves the exterior of the pass-through hole. A blood delivery tube islimited and fixed on the thermostatic box through the pass-through hole, the return pipe realizes the purpose of returning superheated air in the heating system to be neutralized with cold air and returning supercooled air with sub-standard temperature to be reheated, the heating and the heat preservation are separated, the stable temperature of a heat source is realized, so that indirect uniformtemperature control is conveniently realized.

Description

technical field [0001] The invention relates to the field of hemodialysis, in particular to a fixed device for hemodialysis with blood care and temperature control. Background technique [0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution containing the same concentration as the body are inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection. Material exchange, removal of metabolic waste in the body, maintenance of electrolyte and acid-base balance; removal of excess water in the body at the same time, and the whole process of reinfusing purified blood is called hemodialysis.

AI Technical Summary

Problems solved by technology

[0003] In practical applications, the temperature of blood will drop when it flows in the pipeline, and then there are devices for blood heating on the market, but most of the devices have a problem that directly heats the blood to control the temperature, but the temperature control is uniform. The temperature and the intensity of heating are not easy to control, and it is easy to cause local overheating of the blood or insufficient local temperature control.
