FIELD OF THE INVENTION

Our invention is a CAMERA-BASED PATIENT POSITIONING AND BED SORE PREVENTION MONITORING SYSTEM.

BACKGROUND OF THE INVENTION
In today's ICU and critical care environment where patient positioning monitoring, bed sore prevention, and infection control are paramount, traditional contact-based positioning sensors and manual monitoring systems present significant limitations.

To address these challenges, Criterion Tech Pvt. Ltd., has developed an innovative Camera-Based Patient Positioning and Bed Sore Prevention Monitoring System utilizing cutting-edge computer vision technology that enables completely contactless detection of patient positioning parameters.

This Camera-Based Monitoring System combines advanced computer vision algorithms with real-time AI analysis to capture patient positioning data through the detection of body landmarks, orientation angles, and bed configuration parameters. The system operates without any physical contact with the patient, eliminating discomfort and reducing infection transmission risks while maintaining clinical-grade accuracy for bed sore prevention protocols.

Being edge-processed, the system ensures complete patient privacy and has minimal regulatory compliance requirements, making it easier to deploy across various ICU and healthcare settings.

The system features revolutionary privacy-first design where all patient images are immediately processed and blurred to protect patient identity, with original image data destroyed locally within seconds of parameter extraction. The advanced edge computing architecture ensures that no identifiable patient data ever leaves the monitoring device, providing unprecedented privacy protection while maintaining accurate clinical monitoring capabilities.

In ICU environments, this revolutionary system provides automatic monitoring of critical patient positioning parameters - body orientation, head elevation, bed angles, and movement patterns - without requiring any intervention from healthcare staff. Nurses and doctors can obtain accurate positioning data and bed sore risk assessments simply by installing the device in the patient room, eliminating the time-consuming process of manual position checks and sensor application. This automation significantly reduces workload on clinical staff while ensuring continuous, uninterrupted positioning monitoring for optimal bed sore prevention.

PRIOR ART SEARCH
Hospital bed state detection via camera: A system for monitoring a room of a patient includes a server and a monitoring device. The monitoring device is configured to obtain at a first time a first image of at least a part of the room; identify a first state of the patient based on first image; obtain at a second time a second image of the at least the part of the room; identify a second state of the patient based on the second image; and, in response to the first state being different from the second state, sending a first notification to the server. The server is configured to, in response to receiving the first notification, set a monitored condition of the patient to a first value.
