PHYSIOLOGICAL MEASUREMENT DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18667442 titled 'PHYSIOLOGICAL MEASUREMENT DEVICE

The abstract describes a physiological measurement device that flexes to position an optical assembly over a tissue site, transmitting optical radiation into the tissue and receiving the attenuated radiation after passing through pulsatile blood flow.

• Device body with base, legs, and optical housing
• Optical assembly in the housing
• Flexes to position housing over tissue site, then unflexes to attach housing and illuminate tissue
• Optical assembly transmits and receives optical radiation through tissue with pulsatile blood flow attenuation

Potential Applications: - Medical monitoring of blood flow and tissue oxygenation - Non-invasive measurement of physiological parameters - Research in vascular health and perfusion monitoring

Problems Solved: - Invasive procedures for blood flow measurement - Limited access to real-time tissue oxygenation data - Difficulty in continuous monitoring of physiological parameters

Benefits: - Non-invasive and continuous monitoring - Real-time data on tissue oxygenation and blood flow - Improved understanding of vascular health and perfusion dynamics

Commercial Applications: Title: "Non-Invasive Physiological Monitoring Device for Healthcare Applications" Potential commercial uses in healthcare settings for patient monitoring, research institutions for physiological studies, and sports science for performance optimization.

Questions about the technology: 1. How does the device differentiate between different types of tissue in terms of optical radiation attenuation? 2. Can the device be used for long-term monitoring of chronic conditions such as peripheral vascular disease?

Frequently Updated Research: Ongoing studies on the accuracy and reliability of the device in various clinical settings and patient populations.

Original Abstract Submitted

An physiological measurement device provides a device body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.
