Description
Technical field
The present invention relates to medical-therapeutic treatment of human body core temperature monitoring device technical fields, the in particular to measurement method of abdomen core temperature
And equipment.
Background technique
Human body DIE Temperature is a kind of important medical vital sign, is being had a fever and body temperature in a variety of situations such as postoperative rehabilitation
It is to generally require to need in the meantime long-term to the progress of human body DIE Temperature as physical rehabilitation situation is constantly changed
The human body DIE Temperature of real-time measurement, medical treatment measurement refers to the temperature of body interior thoracic cavity, abdominal cavity and nervous centralis, due to human body
Nuclear temperature not Easy Test clinically often represents body temperature with the temperature of ear-drum, forehead, oral cavity, armpit, rectum etc., and practical
The core temperature difference 0.2-0.8 degree with the measurement of these positions only, rectal temperature is closest to human body DIE Temperature
's.Human body DIE Temperature deviates 1 degree Celsius of normal range (NR) and is then likely to compromise life, so can long-term, real-time, accurate and fast
To measure human body DIE Temperature most important.
But human body DIE Temperature is measured at present, it is to be inserted into the conduit with temperature sensor by invasive method
Human body DIE Temperature is obtained in human vas or in rectum, these methods may generate side effect, infection, blood vessel solidification
Etc. consequences, be great pain for patients and uncomfortable.And be inserted into human vas or rectum in thermometric not yet
Too suitable long-term detection in real time.
Or DIE Temperature is estimated by measurement shell temperature, this is by hand or thermocouple, thermistor, electronics temperature
Sensor, infrared temperature measuring instrument and forehead contact are spent, can estimate DIE Temperature, but due to human skin and other
Temperature drop inside and outside intermediate structure, the temperature and DIE Temperature of these sensors acquisition have certain error, this temperature is missed
Difference is not constant, is significantly changed according to factors such as difference, perspiration, room temperature, measuring point, the fat thickness of individual,
And forehead thermometric inconvenience fixation and wearing also unsuitable long-term detection in real time.
DIE Temperature is estimated also by oral temperature device, and thermometer is placed on the sublingual temperature measured and core temperature
Degree difference 0.2 degrees centigrade, however even if oral temperature there is also small error, such as breathe, ingest or other cavitys activity
Also result in the error of measurement temperature.Pass through oral cavity measurement core temperature also unsuitable long-term monitoring in real time.
Also by the infrared thermometer of plug-in type ear canal, eardrum is opposite to abut brain and relatively accurate reflection core body
Temperature, but everyone ear canal shapes are different from, and the bending of ear canal may can hinder to connect with factors such as earwax in ear canal
Nearly eardrum leads to the increase for measuring temperature error.Contact of the thermometer with eardrum easily causes ear infection, this is serious doctor
Treatment situation.Pass through eardrum measurement core temperature also unsuitable long-term monitoring in real time.
It is put into oxter also by by temperature sensor, by stepping up armpit, so that oxter is formed closed environment prevents heat
Amount is lost, to obtain estimation DIE Temperature, usual auxillary temperature differs 0.2-0.8 degrees Celsius than DIE Temperature, however oxter
For temperature there is also small error, spy is that not tolerant oxter keeps closed environment when arm activity, standing, taking thing, is caused
Measurement temperature error sharply becomes larger.Pass through oxter measurement core temperature also unsuitable long-term monitoring in real time.
Obtained also by a temperature sensor is fixed in abdomen abdomen close to enteron aisle temperature, thus to estimate people
Body DIE Temperature, but because the difference of individual causes error to become larger, if the adipose tissue of cradle abdomen is than relatively thin, skin
Be close to internal enteron aisle thus the temperature surveyed can more accurately antimer inner core temperature, with the growth of people, abdominal tissues
With fat is improper thickens, the decline of the temperature of organization internal causes the temperature measured by this method from the error of DIE Temperature
Constantly become larger, not can accurately reflect the DIE Temperature of all ages and classes, the different crowds such as fat or thin.
Summary of the invention

Work as kiWhen≤0.00001, that is, think in all detection parameters reach stable state.
DIE Temperature T is measured firstxPeriod as a measurement period, start in second measurement period
When, need to only obtain temperature sensor (3) close to intestinal tract skin surface temperature numerical value, core temperature that the first measurement period is obtained
Spend TxIt measures with second close to intestinal tract skin surface temperature numerical valueDifference, as internal enteron aisle DIE Temperature and body surface temperature
The temperature T of the temperature losses part of degreeIt mends, second measurement period obtain close to intestinal tract skin surface temperature numerical valueIn addition
TIt mendsNumerical value afterwards is as second measurement period enteron aisle DIE Temperature Tx.And so in third measurement period with same side
Formula obtains enteron aisle DIE Temperature Tx。
In conjunction with shown in Figure 12, describing can be by the T that obtains in same a period of timexTemperature group data use minimum two
Multiplication minimizes program or other coupled equations solvers to obtain the more accurately temperature number close to dashed centre line region
Value, to provide DIE Temperature Tx。
Obtain temperature sensor effective readings when, by variable heater to temperature sensor close to skin surface apply
Add 1 DEG C or so of fixed temperature to disturb, then obtain effective readings of temperature sensor, with provide to because in skin heat loss due to produce
The estimation that raw temperature reduces is corrected, this method is computationally concise effective, but because of actual skin temperature
It is the factors such as volatilization, environment temperature, cross-ventilation of the skin surface sweat variation as caused by many factors that degree, which reduces,
It may cause some errors, but according to aforementioned product structure of the invention and wear mode, offer one opposite envelope can be provided
The above-mentioned generation for leading to error is avoided in the small area closed.
It should be noted that measuring device of the invention can also include for other physiological parameters except temperature collection
Sensor, such as: blood oxygen transducer, heart rate sensor, blood pressure sensor, blood glucose sensor etc., obtained data include
Core temperature and other optional readings, the numerical value such as blood oxygen, heart rate, blood pressure, blood glucose carry out display storage, or transmission
To host computer.
Above is only a specific embodiment of the present invention, but structure feature of the invention is not limited thereto, the present invention
It can be used on similar product, within the field of the present invention, made changes or modifications are all by any those skilled in the art
Cover within the scope of the patent of the present invention.
