AI Technical Summary

Benefits of technology

This patent describes a system for measuring various physiological parameters of a person's body. The system includes a device that detects the parameter and sends a signal to a reading device, which then calculates the difference between the first and second measurements of the parameter. If the difference is small, the system stores a flag that indicates that the parameter has stabilized over time. This allows for the quick and accurate detection of stable parameters without the need for additional measurements. The system can also be used to measure temperature and predict when it will stabilize.

Problems solved by technology

The measurement of a body temperature using a thermometer device is not typically able to be performed instantly and requires an extended period of time up to at least a few minutes.
Such measurement time delay can be caused by the heat capacity of a sensing element of the thermometer device and the fact that applying the thermometer device to the patient tissues or skin draws down the temperature of the tissues or skin in the immediate region of the thermometer device.

Embodiment Construction

[0017]Various embodiments will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views.

[0018]In general, a system in accordance with an exemplary embodiment of the present disclosure provides a quick response in monitoring a physiological parameter of a subject, thereby allowing instant measurements of the parameter associated with the subject. In some examples, the system of the present disclosure includes a body-worn sensing patch (e.g., a temperature monitoring patch) that is activated to detect a physiological parameter (e.g., a body temperature) of the subject and communicate with a reading device via a wireless communication link. In some examples, the sensing patch is designed for a single use. When the sensing device is first attached to the subject's body or reattached to the body after detached, there exists a thermal unbalance between the subject's body and the sensing device t...

Abstract

A physiological parameter measuring system includes a parameter sensing device attachable to a body of the subject. The sensing device detects at least one physiological parameter when activated, and a reading device monitors a temperature variation over time and determines whether the parameter has been so stabilized as to be reliably detected. A stability indication flag can be stored in the system so that subsequent monitoring of the parameter is instantly performed.

Description

BACKGROUND[0001]The measurement of a body temperature using a thermometer device is not typically able to be performed instantly and requires an extended period of time up to at least a few minutes. Such measurement time delay can be caused by the heat capacity of a sensing element of the thermometer device and the fact that applying the thermometer device to the patient tissues or skin draws down the temperature of the tissues or skin in the immediate region of the thermometer device.SUMMARY[0002]In general terms, this disclosure is directed to a physiological parameter measuring system. In one possible configuration and by non-limiting example, the system is configured to determine the stability of a parameter before the parameter is detected, and a stability indication is used for instant measurement of the parameter. Various aspects are described in this disclosure, which include, but are not limited to, the following aspects.[0003]One aspect is a system for monitoring a physiol...
