Description

Technical Field

[0001] The invention belongs to the field of automatic peritoneal dialysis, and in particular relates to a pump noise control method and system for automatic peritoneal dialysis. Background Art

[0002] Peritoneal dialysis is one of the main treatments for patients with end-stage renal disease. It mainly uses the human peritoneum as a semipermeable membrane to remove excess water, metabolites and toxins from the body, thereby achieving the purpose of blood purification and replacing kidney function. Automated peritoneal dialysis is achieved by injecting peritoneal dialysis fluid into the human peritoneal cavity through an automated peritoneal dialysis device connected to a dialysis line. Automated peritoneal dialysis has gradually become widely used because of its advantages such as significantly improving the quality of life of patients, good dialysis effects, and less prone to complications related to the operation.

[0003] Automated peritoneal dialysis machines generally use the patient's sleep time at night to exchange peritoneal dialysis fluid to remove toxins. Due to the characteristics of nighttime operation and the fact that the tubing on the patient side of the automated peritoneal dialysis tube set should not be too long, the automated peritoneal dialysis machine is generally near the user, and the operating noise of the equipment will greatly affect rest.

[0004] The working noise of existing automatic peritoneal dialysis is about 45dB with physical sound insulation measures on the shell and inside the equipment, and about 55dB when the cover is open and exposed. Noise analysis shows that the main source of working noise comes from the pump. When the pump is working, the gas flow at the pump outlet is too large and unstable, which will cause a lot of noise when entering the air path. Although the shell and interior of the equipment have been physically noise-reduced, the ambient noise is relatively loud during daytime use, which may not affect the treatment experience. However, when used at night, the physical noise reduction effect is not obvious, and there is still a lot of noise, which affects the user experience. Therefore, a pump noise control method and system for automatic peritoneal dialysis can well achieve control and noise reduction from the source, which is of great significance to improving the user experience of automatic peritoneal dialysis machines. Summary of the invention
