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.

In foretell hemodialysis is with nursing bed, the backward flow mechanism includes that retaining cavity bottom runs through a back flow of fixed mounting, still install the pump body on the back flow, the one end and the hot-water tank upper end intercommunication of retaining cavity are kept away from to the back flow.
In the above-mentioned nursing bed for hemodialysis, the upper end of the hot water tank is also provided with a water filling port.
Compared with the prior art, this nursing bed for hemodialysis's advantage lies in:
1. the trigger mechanism is arranged to be matched with the hot water tank, the communicating pipe, the water storage cavity and the coiled pipe for use, and a patient can guide hot water into the bed body to supply heat to the bed body by pulling the second pull rope on the bed head, so that the operation is labor-saving and convenient, the control is easy, and no other side effect exists;
2. through setting up backflow mechanism cooperation retaining cavity and hot-water tank and using, can take out the interior refrigerated water of retaining cavity and heat again in the hot-water tank, recycle, the environmental protection of economizing on water more.
