Description

Dialysate heating device

Technical Field

The utility model relates to the technical field of dialysis, in particular to a dialysate heating device.

Background

Dialysis is a therapeutic approach for the treatment of renal failure. When kidneys fail to properly filter and remove waste and excess fluids from the body, dialysis can help remove such waste and fluids to maintain balance and health of the body. Dialysis is largely divided into two types: hemodialysis and peritoneal dialysis.

Hemodialysis is a process in which blood from a patient is drawn out of the body through a dialysis machine, filtered and cleaned through a filter (dialyzer), and the treated blood is returned to the patient. The dialysis machine simulates the kidney function and can remove waste, salt and excess fluid from the blood while regulating the electrolyte balance.

Hemodialysis mainly comprises the following steps: (1) establishing a vascular access: before the beginning of a dialysis treatment, it is necessary to establish a passageway in the patient's blood vessel, typically by selecting an arteriovenous fistula (AVG) or using a temporary dialysis catheter; (2) dialysis machine connection: the patient's blood is drawn off and flows through a dialysis machine in which there is a filter (dialyzer) and dialysate which is contacted with the blood through a semi-permeable membrane in the filter to assist in the removal of waste; (3) blood cleaning: the blood passes through a filter and a dialyzate in a dialysis machine, and metabolites, toxins, redundant liquid and the like are removed, so that the internal environment disorder is corrected; (4) blood reinfusion: the filtered blood is returned to the patient until a dialysis treatment is completed.

In steps (2) - (4), the temperature of the blood decreases during the process of flowing the blood from the patient back to the body after cleaning through the dialyzer, which may be uncomfortable for the patient, and the blood comes into contact with a large amount of unheated dialysate, especially in the case of low air temperature, which may even lead to severe hypothermia, which may endanger the patient's life. Therefore, how to reduce the temperature difference between the reflowed blood and the blood in the human body, improve the dialysis comfort level, and ensure the constancy of the temperature during the perfusion of the dialysate during the peritoneal dialysis becomes a technical problem to be solved urgently.
