Dialysis system with blood detection and patient movement monitoring
The granted patent US12070540B2 describes an innovative dialysis system designed to enhance patient safety and treatment efficacy during dialysis procedures. Central to this system is a dialysis machine that incorporates a dialysate flow path and an extracorporeal blood flow path, which connects to a patient's limb at a blood access point. A key feature of the system is a detector assembly positioned adjacent to the access point, which includes a wetness detector for blood detection, an integrated inertial measurement unit (IMU) for monitoring the patient's pulse, and a transmitter for relaying critical data to the dialysis machine. The IMU can measure the pulse by either monitoring blood vessels or blood flow through the dialysis system's tubing.
The patent further outlines functionalities that enhance the system's responsiveness to patient conditions. Upon detecting blood, the dialysis machine can issue alerts or halt treatment as necessary. Additionally, the system can analyze changes in pressure related to the patient's pulse and limb movement, allowing it to correlate these factors and adjust treatment accordingly. If the IMU detects a lack of limb movement alongside pressure changes, the machine can again issue alerts or cease operation. The detector assembly is designed to be wireless and battery-powered, with provisions for monitoring its usage and battery life, ensuring continuous and reliable operation during dialysis treatments.
