AI Technical Summary

Technical Problem

Existing miniaturized dialyzers are difficult to clean effectively at accident sites, causing impurities to enter the patient's blood vessels, posing a risk of infection and preventing timely hemodialysis treatment.

Method used

A self-cleaning hemodialysis machine was designed, which includes a pre-fill cleaner. It uses high-speed airflow and cleaning fluid to exhaust air and clean the arterial fistula needle and venous fistula needle when they are connected to the outside world, thereby achieving automatic cleaning of the arterial fistula needle and venous fistula needle.

Benefits of technology

The cleaning of arteriovenous fistula needles and venous fistula needles can be completed before treatment, ensuring timely hemodialysis treatment, reducing the risk of infection, and is suitable for emergency treatment of patients with sudden illnesses at the scene of an accident.
