[0001]
[Industrial applications]
The present invention relates to a thermometer that is worn on the ear to measure the body temperature in the ear, and measures the body temperature in the ear to grasp the state of head blood flow (balance between left and right) to prevent stroke and cerebral infarction, The present invention relates to an inspection device for performing an inspection.
[0002]
2. Prior Art and Problems to be Solved by the Invention
Devices that are worn in the ear canal to measure body temperature are more widely known than before. In addition, the measurement mainly focuses on the measurement of the eardrum temperature, and in particular, a device that does not cause an error depending on the measurement position has been proposed.
[0003]
For example, a specific mechanism for measuring a body temperature in an ear canal by an infrared ray amount is disclosed in Japanese Patent Application Laid-Open No. 2001-54505. No. 139849 and JP-A-2001-54505.
[0004]
Techniques for measuring body temperature with a plurality of directional directions are disclosed in JP-A-8-275924 and JP-A-7-184866.
[0005]
Further, electrical processing and correctness detection processing of the temperature detected by the sensor are disclosed in JP-A-2001-346776 and JP-A-2001-340302.
[0006]
Japanese Patent Laid-Open No. 6-90909 discloses that a so-called headphone style is used as a means for mounting the ear canal thermometer at an accurate position.
[0007]
The aforementioned thermometer is intended to measure an accurate body temperature, and is provided with a plurality of sensors having a plurality of directivities, and is also intended to improve inaccuracies between wearing states of the ear canal of the instrument.
[0008]
By the way, when the body temperature of the ear canal is measured, the accuracy of the wearing state is determined, and the body temperature in the ear canal is measured because the body temperature in the ear canal is not constant. That is, the artery that supplies blood to the brain and the draining vein are close to each other around the eardrum, and the body temperature changes due to fluctuations in blood flow or distance to blood vessels.
[0009]
Therefore, the present invention has proposed a testing apparatus which detects this body temperature displacement (temporal displacement and positional displacement), grasps the cerebral blood flow state (particularly, right and left blood flow balance) of the test object, and can apply it to various applications. Things.
[0010]
[Means to solve the problem]
The left and right blood flow balance testing device of the present invention incorporates an in-ear body temperature measurement unit including a temperature sensor having directivity to at least the front of the eardrum and the back of the head when the ear canal is worn. Two ear wearing bodies, an arch-shaped wearing urging unit that holds the ear wearing bodies at the distal end portions in opposite states and urges them in the facing direction, and performs a predetermined arithmetic processing on the measurement results of the measuring unit. And a processing unit for displaying.
[0011]
Therefore, the ear wearing body is worn at a normal position by the use of the wearing urging part, and the body temperature of the predetermined part (directional direction part) is measured by the in-ear body temperature measuring part, and the arterial flow and the venous flow are determined from the temperature difference of each part. You can know left and right cerebral blood flow balance (brain activity).
[0012]
Further, if the directional temperature sensor measures the temperature at many points around the eardrum (the invention of claim 2), the brain activity can be grasped more accurately.
[0013]
In addition, when the change in brain activity is grasped based on the temporal displacement of the measurement result (the invention of claim 3), the psychological movement of the measurer is also known by observing the temporal change together with the addition of an external factor. Can be applied (it can be applied as a lie detector).
[0014]
Further, by providing the ear-wearing body with the vibration detecting unit (the invention of claim 4), not only measurement based on blood flow but also noise caused by an aneurysm can be picked up.
[0015]
Further, if a sound generating mechanism for amplifying an external sound and generating a predetermined volume is incorporated in the ear wearing body (the invention of claim 5), the external sound can be easily heard in a state where the ear wearing body is worn. It can also be applied to hearing tests.
[0016]
Embodiment
Next, an embodiment of the present invention will be described. The device shown in the embodiment includes two ear wearing bodies 1, a wearing urging unit 2, and a processing unit (such as a personal computer) 3.
[0017]
The in-ear body 1 incorporates a plurality of in-ear body temperature measuring units 11 having a predetermined directivity, a vibration detecting unit 12, and a sound generating mechanism 13, and outputs detected data to the processing unit 3 or outputs audio data. It has a data line 14 for inputting.
[0018]
When the in-ear temperature measurement unit 11 wears the ear wearing body 1 in the ear, as illustrated in FIG. 3, the center part A of the eardrum A, the outer part B, C, D, E, H, and G A waveguide is provided so as to have directivity and has a temperature sensor for detecting infrared rays guided by each waveguide. In particular, as the directional direction, a portion where the influence of the artery B easily appears immediately (front of the head in the eardrum) b, a portion where the influence of the artery B hardly appears immediately (back of the head in the eardrum) e, and the effect of the vein C immediately Optimally, a portion that is likely to appear or a portion C, D, or G that is an intermediate portion of the above portion is optimal. Of course, the intermediate portions C, D, and G may be omitted. These temperature measurement data are sent to the processing unit 3 as independent data for each sensor.
[0019]
The vibration detection unit 12 detects air vibrations minutely, and can grasp the blood flow sound of the artery B.
[0020]
The sound generation unit 13 can surely hear external sounds (for questions for hearing at various medical examinations and questions when used as a lie detector) even when the ear-wearing body 1 is worn on the ears. Or to generate a predetermined sound to determine whether or not it is possible to hear.
[0021]
The mounting biasing portion 2 is formed of an elastic body, and the ear mounting body 1 is attached to both end portions so as to face each other. When the insertion portion of the ear mounting body is mounted in the ear, no positional displacement occurs. As described above.
[0022]
The processing unit 3 compares the in-ear body temperature (infrared ray amount) of each part (a, b, c, d, e, f, g) detected by the in-ear body temperature measuring unit 11 according to the purpose of use, It incorporates a program for calculating the temporal displacement and displaying the result.
[0023]
Specifically, by comparing the temperature in the left and right ears by all the sensors with the corresponding portions, it is possible to know the balance between the left and right cerebral blood flows. Further, when looking at the temperature of the part B close to the artery B, the temperature of the part E where the influence of the artery B hardly appears immediately, and the temperature change to the part where the influence of the vein C readily appears easily, for example, A sudden change in temperature indicates an increase in blood flow to the brain, indicating that the brain has transitioned to an excited state (can be applied as a lie detector).
[0024]
Further, it is possible to confirm whether or not the above-mentioned temperature change of the part B depends only on the arterial blood flow by corresponding to the temporal displacement of the detected temperature value of the part E (correction based on the detection result is possible). .
[0025]
Therefore, by measuring the temperature of each part and comparing and verifying the positional displacement and temporal displacement, the state of cerebral blood flow can be grasped, and the stroke and brain It can be used as a diagnostic device in various medical fields, for example, it can be used as a material for measures to prevent diseases related to head blood flow such as infarction.
[0026]
Further, by incorporating the vibration detection unit 12 and the sound generation device 13, the blood flow sound can be detected and used as a device for detecting an aneurysm, etc., and the transmission of external sound is facilitated, so that the device as a lie detector can be used. It also performs its function and can be used as a hearing test device.
