AI Technical Summary

⚠Technical Problem

Existing wrist hemostasis systems do not take into account the differences in patients' preoperative bleeding risk levels when setting compression parameters, resulting in insufficient or excessive compression intensity. Furthermore, they lack real-time monitoring and dynamic adjustment of local blood flow status, making it difficult to effectively identify signs of bleeding and adjust compression strategies, thus affecting hemostasis efficacy and safety.

⚗Method used

Patient data is acquired through the preoperative assessment module. Preoperative bleeding risk level is generated using platelet count, INR, APTT and anticoagulant data. Individualized initial compression pressure and duration are set. Hemostasis stability index is generated through PPG signal and bioelectrical impedance monitoring to achieve dynamic adjustment of compression intensity and duration.

🎯Benefits of technology

It enables individualized matching and dynamic feedback control of compression parameters, improving the safety, stability, and adaptability of the wrist hemostasis process, and reducing the risk of oozing and rebleeding.

Abstract

The application discloses a wrist hemostasis system and method based on preoperative evaluation, and relates to the technical field of intelligent medical treatment, and comprises the following steps: acquiring patient data and corresponding medication data, inputting the patient data into a preset weighted scoring model, and outputting a preoperative bleeding risk level; the patient data comprises platelet count, international normalized ratio (INR), and activated partial thromboplastin time (APTT); according to the preoperative bleeding risk level, setting an individualized compression initial pressure and a basic compression time length; the compression initial pressure is a fixed multiple of systolic pressure, and the compression time length is a matching value in a preset interval; after the hemostasis device is controlled to be boosted to the initial pressure, a stepwise decompression program is executed, the compression pressure is gradually reduced, and a distal PPG signal is synchronously monitored; when the PPG signal is stable and reappears, the corresponding pressure is recorded as a blood flow recovery pressure; while reducing the risk of bleeding and rebleeding, the safety, stability and individual adaptation degree of the wrist hemostasis process are improved.
