Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a hemodialysis monitoring and nursing device capable of adjusting filtration volume. Background Art

[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing similar concentrations to the body are exchanged inside and outside the hollow fibers through diffusion, ultrafiltration, adsorption and convection principles to remove metabolic waste from the body, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] For example, a blood dialysis monitoring and nursing device with adjustable filtration volume, disclosed in publication number CN110354326A (CN110354326B), includes a base, a storage tank and a dialysis tube. The blood filtered by the secondary filter is discharged through a discharge tube, which is convenient for medical personnel to collect blood for testing and check whether the initial dialysis effect of the blood is achieved. After the predetermined effect is achieved, the switch valve on the third connecting tube is closed, so that the dialyzed blood is discharged from the finished product tube, which is convenient for the next step of processing. If the predetermined effect is not achieved, the device cannot be used and needs to be repaired in time to avoid danger to the patient. After the third detection tube detects that the blood dialysis has achieved the predetermined effect, the blood is discharged from the finished product tube. When the blood passes through the discharge tube, the heating tube heats the blood in the discharge tube. When the dialyzed blood is heated to a temperature suitable for the human body, it is transported back to the human body to avoid harm to the human body. By observing the actual situation of the patient, the flow of the limiting valve is controlled to protect the patient's safety.

[0004] When medical staff in this patent perform hemodialysis on patients, the blood filtration volume in the equipment remains unchanged. Since the patient's physical condition is different from before, the patient's physical recovery is slower after hemodialysis.
