AI Technical Summary

Technical Problem

Existing anti-pulling technologies lack proactive and real-time physical intervention mechanisms, have a high false alarm rate, limited monitoring dimensions, rigid constraint methods, and make it difficult to balance comfort and safety.

Method used

An anti-extubation device based on artificial intelligence early warning was designed, which includes a sensing module, a decision-making module, and a constraint module. It uses an image acquisition device to monitor the patient's kinematic data in real time, identifies extubation behavior characteristics through a neural network model, and provides on-demand constraint through a dual locking mechanism of the arm and hand units.

Benefits of technology

It significantly reduced false alarm rates and unplanned extubation events, improved patient comfort and safety, reduced the duration of mechanical restraint and pharmacological sedation, and lowered the risk of complications.

Abstract

The invention relates to a pipe pulling prevention device based on artificial intelligence early warning. The system mainly comprises a sensing module, a decision module and a constraint module. The sensing module is responsible for collecting human body kinematics data of a patient; the decision-making module analyzes whether the tube drawing tendency exists and outputs a control instruction; a constraint module performs an intervention on the patient in response to the instruction. Wherein the arm unit is switched between a locking fixed mode and an unlocking movable mode through a hinge connected with a large arm ring and a small arm ring, and the movement of an elbow joint is limited; and the hand unit is switched between a folding hiding mode and an unfolding releasing mode through the protective cover in the bracelet, so that a space for wrapping the hand is formed, and intelligent anti-tube-drawing protection is realized. Compared with the prior art, the method has the advantages of realizing active defense closed loop, giving consideration to comfort and safety and the like.
