Abstract

This invention discloses a portable hemodialysis accessory with a blood leakage sensor, relating to the field of hemodialysis monitoring technology. The invention includes a housing, with a venous vessel fixation seat and an arterial vessel fixation seat connected to its two sides respectively. Each of the venous and arterial vessel fixation seats has a vessel slot on one side. A monitoring system connected to the leakage sensor is disposed within the housing, and a control panel and an audible and visual alarm are disposed on the outside of the housing and connected to the monitoring system. This invention, through the monitoring system within the housing, can receive the detection signal transmitted by the leakage sensor in real time. When blood leaks into the vessel slot and comes into contact with the leakage sensor, the monitoring system quickly analyzes and processes the signal, immediately triggering an alarm light on the control panel and activating the audible and visual alarm. This dual audio and visual alert allows medical personnel to detect the abnormality immediately.
