Description

Hemodialysis is with nursing bed

Technical Field

The invention relates to the technical field of medical care, in particular to a nursing bed for hemodialysis.

Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The blood and electrolyte solution with similar organism concentration are subjected to substance exchange inside and outside one hollow fiber by the principles of dispersion, ultrafiltration, adsorption and convection, so that the metabolic waste in the body is removed, the electrolyte and acid-base balance is maintained, excessive water in the body is removed at the same time, and the purified blood is returned.

Since a patient is drawn off a part of blood during hemodialysis, the patient feels cold remarkably, and the hemodialysis time is long, so that the patient needs to be externally heated. The existing hemodialysis heating equipment usually adopts an electric blanket, but the electric blanket carries radiation effect, so that the health hidden danger exists in the long-term use of patients.

To this end, we propose a care bed for hemodialysis.
