An optical approach for reliable in-situ early blood detection at catheter extraction points

Country of Origin: Singapore
Reference Number: TOSG20160927008
Publication Date: 4 October 2017

Summary

A Singapore hospital has developed a biomedical sensing, monitoring and alerting device which is capable of detecting and differentiating active re-bleeding from other fluids at the central venous catheter extraction site. 

The organisation is interested in establishing license agreements and research cooperation agreements with commercialization partners such as SMEs and research institutions in the healthcare industry.

Description

The solution offers a real-time monitoring system that triggers an alert after blood leakage is detected. When the central venous catheter is removed, this device will be placed between the dressing and the compressive bandage that holds the medical gauze in place. 



There are two conditions and systems in the technology: 

1) detection of fluid i.e. water, urine, blood; 

2) differentiation of blood from the other fluids. 



The first system is based on the light absorption characteristics of different fluids. Two wavelengths are used in this technology: 950 nm to expose the presence of fluid, and 528 nm to indicate the presence of hemoglobin (red blood cells). A parallel method to reveal fluid presence based on electric resistive pattern of different fluids is another system in this device. Blood, urine, and water have different electrical conductivity. Therefore, a simple threshold mechanism will be sufficient to manifest the presence of water. 



In the event where blood leakage is detected, the solution will trigger an alarm via a remote warning system through a Low Energy Bluetooth module, and medical attention will be provided



The hospital seeks the following types of partnerships with the SMEs or research institutions:



- Licensing agreements

- Research Cooperation agreements

Advantages and Innovations

This technology will be applicable in the clinical settings where differentiation between blood and other bodily fluids is necessary. Besides monitoring central venous catheter removal site as described, this technology will also be useful for monitoring wounds of patients who have undergone surgery in any other parts of the body.  



Close monitoring of central venous catheter extraction site may not be available and severe bleeding may lead to catastrophic consequences. 



A real time monitoring device that detects blood leakage from wounds and is capable of differentiating blood from other bodily fluid will be advantageous. The solution can potentially provide better patient care where intervention is administered in a timely manner. This device will also trigger an alarm via a remote warning system through a low frequency Bluetooth module which is convenient and efficient for the healthcare providers.

Stage Of Development

Available for demonstration

Requested partner

The Singapore healthcare institution seeks to work with SMEs of all sizes or research/healthcare institutions in a licensing or research cooperation agreement partnership.



The partner sought could be a healthcare institution or healthcare technologies provider.



Under a licensing agreement:

The partner can license the technology to offer as a product or service to their customers.



Under a research cooperation agreement:

The partner can undertake joint development with the Singapore healthcare organisation to offer to introduce new products to targeted markets/segments.
