DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device combining a therapy device and a peripheral circulation monitor, and more particularly to a device suitable for the medical field and the physiotherapy fields such as acupuncture, moxibustion, and chiropractic.

[0002]

2. Description of the Related Art In the medical field and physical therapy field, various therapies such as electric therapy, magnetic therapy, ultrasonic therapy, radiation therapy, drug administration, acupuncture, moxibustion, chiropractic, massage, and phototherapy are performed. In phototherapy, which is one such therapy, for example, a living body light irradiation device and a lamp that irradiates a living body with light having a spectrum ranging from the near ultraviolet region to the far infrared region (Japanese Patent Application Laid-Open No. 8-308943). A composite lamp for irradiating a light beam suitable for a living body in a wide spectral range from the far-infrared region to the ultraviolet region (Japanese Patent Application Laid-Open No. 9-99105), simulated sunlight approximated to natural sunlight by a combination of a plurality of light sources Simulated sunlight irradiation device (Japanese Patent Application Laid-Open No. 9-99106), in which an emission spectrum effective for treatment is superimposed on black body radiation light whose emission intensity gradually decreases in the visible region as the wavelength becomes shorter. A light beam irradiation device for a living body that irradiates a light beam has been proposed.

[0003] The effect of a therapy such as phototherapy can be determined by evaluating the degree of blood circulation. For example, there has been known a method of determining the effect of light treatment or the like by observing the temperature of the body surface of a subject using a thermograph image.

[0004]

As is conventionally done, the determination of the therapeutic effect using thermographic images involves the following:
There are problems with accuracy, real-timeness, and the adjustment of the stimulus applied by the therapy device. When the irradiation light reaches the body surface of the subject, the body surface receives radiant heat, and blood vessels are expanded by the stimulation of the radiant heat. The thermographic image is for measuring and imaging the radiant heat reflected from the body surface, and is not for observing the actual blood flow but for measuring the effect of stimulating the radiant heat. For this reason, it is not always possible to accurately determine the therapeutic effect when using the thermograph image.

[0005] In the treatment apparatus, it is necessary to adjust the optimum intensity of the stimulus to be applied to the subject and the treatment time in accordance with the subject and the degree of the disease. However, usually, the intensity of the stimulus applied to the subject by the treatment device and the treatment time are determined according to a general pattern obtained based on experience, and the control of the treatment device is not necessarily appropriate according to the subject and the degree of the disease. Is not always performed, and over-treatment or inadequate treatment may be performed. In addition, judgment of the therapeutic effect using thermographic images is insufficient in terms of accuracy and real-time performance, and it is difficult to accurately grasp the change in the therapeutic effect performed during the treatment. It is difficult to make accurate and real-time adjustments.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems and to provide a therapeutic device capable of measuring a therapeutic effect accurately and in real time, and to adjust a stimulus applied to a subject. It is an object of the present invention to provide an accurate and real-time treatment device.

[0010] The value of the measurement wavelength and the number of measurement wavelengths of the image data obtained by the image measurement unit can be determined according to the biological information to be obtained. Further, the content of the image calculation performed by the image calculation unit can be determined by a calculation formula determined according to the data type and the number of data of the image data obtained by the image measurement unit and the biological information to be obtained. The light source for irradiating the living body with light in the optical image measurement means can use any light source including a predetermined wavelength, and when the light source used for phototherapy includes the wavelength required for measurement, the light source for measurement is used. And a light source for phototherapy.

[0011] Biological information such as oxyhemoglobin and deoxyhemoglobin obtained by the optical image measuring means indicates a change in blood flow in the peripheral circulation and can be used as an index for judging a therapeutic effect.

When the light emitted from the light source 21 does not include light having a wavelength used for measurement by the optical image measuring means 3, a light source including the wavelength range is added to the light source 21;
As a configuration in which a light source including the wavelength range is separately arranged, the subject 10 is irradiated with light having a wavelength required for measurement by the optical image measurement unit 3. In the case where the wavelength required for the measurement is included in the external light, the configuration in which the external light is applied to the subject 10 in addition to the light source 21 can omit the light source. Light emitted from the light source passes through the stratum corneum / basal layer, which is the epidermis, reaches the dermis / subcutaneous tissue, improves blood flow in peripheral blood vessels, and has the effect of improving peripheral circulation secondarily. . For example, the red region is effective for analgesia, anti-inflammatory, detoxification, circulation improvement, etc., and the yellow region is effective for promoting metabolism, anti-inflammatory, absorption of induration, etc. due to its relatively strong effect on the deep part. Is effective for paralytic diseases and skin diseases.

When the stimulating means 2 irradiates light, an automatic light source intensity adjusting means 41 is provided as the control means 4. The light-source-intensity automatic adjusting unit 41 adjusts the intensity of the light emitted by the light source based on the peripheral circulation state or the therapeutic effect obtained by the optical image measuring unit 3 so as to obtain a predetermined therapeutic effect.

FIG. 3 is a schematic diagram for explaining a configuration example of the optical image measuring means. In FIG. 3, the optical image measuring unit 3 of the treatment apparatus 1 includes a light detecting unit 3a, an image measuring unit 3b, and an image calculating unit 3c. The image data obtained by the image calculation unit 3c is subjected to data processing by the control unit 4 to form a control signal for controlling the stimulus unit 2. This image data can be displayed by the image display processing means 5. Subject 1
0 is stimulated by stimulating means (not shown), and the subject 10 is illuminated with light from the light source 30.
The light emitted from 0 is guided to the light detecting means 3a.
The light detecting means 3a two-dimensionally detects the emitted light with a two-dimensional detector (not shown), and the image measuring unit 3b calculates the wavelength λ
Image data D1 (t1), D2 (t
.., Dn (t1) are obtained as time-series image data of t1, t2,..., And the image calculation unit 3c performs a calculation process on the time-series image data.

Here, the image data D1 (t1), D2
(T2),... Represent not a single numerical value but a representative pixel matrix. For example, in the case of a 100 × 100 image of 10,000 pixels, D1 (t1) is originally 10
It has an amount of 10,000 total pixels represented by a matrix of 0 rows × 100 rows. Here, in order to simplify the notation, one of the pixels is represented as D1 (t1). Therefore, when D1 (t1) appears during the calculation,
It means that the same numerical value has the total number of pixels of the matrix.

The operations f, g, and h are examples of image operations performed by the image operation unit 3c, and include a plurality of image data having different measurement times for a plurality of wavelengths from time-series image data output by the image measurement unit 3b. Is typically used to calculate the temporal change rate of the image, and the biological information is obtained based on the calculation. For example, the operations f, g, and h are the wavelengths λ1, λ
2,... Λm are calculated using the image data at times ta, tb, and tc as variables. Three times (ta, t
As a set of (b, tc), for example, first (t1, tc)
2, t3), then (t2, t3, t4), (t3, t
(4, t5), at sequentially shifted times,
An image operation defined by f, g, and h is performed.

For example, when obtaining the oxyhemoglobin (oxygenated hemoglobin) variation and the deoxyhemoglobin (deoxygenated hemoglobin) variation in the living body,
The image measurement unit 3b measures image data of two wavelengths over time. The image calculation unit 3c calculates the following formulas (1), (2), and 4 for the four image data obtained by the image measurement unit 3b from the image data of two wavelengths at two times.
As shown in (3), each value is multiplied by a predetermined weight, and an arithmetic process of adding and subtracting these values is performed to obtain an oxyhemoglobin variation and a deoxyhemoglobin variation.

[ΔOxyHb], [ΔdeOxyHb] [ΔOxyHb] = k1 × D1 (t2) + k2 × D2 (t2) −k1 × D1 (t1) −k2 × D2 (t1) [ΔdeOxyHb] = k3 × D1 (t2) + k4 × D2 (t2) −k3 × D1 (t1) −k4 × D2 (t1) (1) [ΔOxyHb], [ΔdeOxyHb] [ΔOxyHb] = k1 × D1 at the second time point (T3) + k2 × D2 (t3) −k1 × D1 (t2) −k2 × D2 (t2) [ΔdeOxyHb] = k3 × D1 (t3) + k4 × D2 (t3) −k3 × D1 (t2) −k4 × D2 (t2) (2) [ΔOxyHb], [ΔdeOxyHb] [ΔOxyHb] = k1 × D1 (t4) + k2 × D2 (t4) −k1 × D1 (t3) −k2 × D2 ( t3) [ΔdeOxyHb] = k3 × D1 (t4) + k4 × D2 (t4) −k3 × D1 (t3) −k4 × D2 (t3) (3) where D1 (t) is at time t of wavelength λ1. A value representing one pixel of image data is shown, and D2 (t) is a wavelength λ2
3 shows a value representing one pixel of the image data at time t.

In the above equations (1), (2) and (3),
[ΔOxyHb] is the pixel value of the variation of oxyhemoglobin, and [ΔdeOxyHb] is the pixel value of the variation of deoxyhemoglobin. The value of [[Delta] OxyHb] at the first time point is four pixel values D1 obtained from a total of four measurement images of two wavelengths at time points t1 and t2 as in equation (1).
(T1), D2 (t1), D1 (t2), D2 (t2)
Is multiplied by (−k1, −k2, k1, k2) as a weight, and is added. The value of [ΔdeOxyHb] at the first time point is the same as the original pixel value D1.
(T1), D2 (t1), D1 (t2), D2 (t2)
Are multiplied by (−k3, −k4, k3, k4) as weights and added.

As shown in equations (2) and (3), the values at the second and third time points are respectively shifted from time (t1, t2) to (t2, t3), (t3, t4). You can ask by going. Note that the original pixel value D1
(T1), D2 (t1), and the like can be obtained from the output value of the two-dimensional detector or a value obtained by logarithmically converting the detector output. Note that since the above calculation is performed for each pixel, the obtained image is an image in which the variation amount of oxyhemoglobin or deoxyhemoglobin is set to each pixel.

The calculation example of the optical measuring means shown in FIG. 4 is a calculation example of an image in the case of measuring at two wavelengths λr and λg. When the measurement times are t1, t2, t3, t4, t5,..., The signal values at each time of each pixel of the image data based on the wavelength component of the wavelength λg are G1, G2, G3, G4, and G, respectively.
, And the signal values at each time of each pixel of the image data based on the wavelength component of the wavelength λr are R1, R2, R
3, R4, R5,... Here, the signal value of each pixel is represented as a representative of each pixel of the CCD. For example, in a 512 × 600 CCD, each of 300,000 pixels has a signal value corresponding to a light receiving image. .

The magnitudes of the pixel signal value Gi at the wavelength λg and the pixel signal value Ri at the wavelength λr are 0 ≦ Gi, Ri ≦ 4095 (409
(6 gradations), and when the values of Gi and Ri are small, the light intensity is low, and when the values of Gi and Ri are large, the light intensity is high. In order to obtain the processed image, the image data Gi of the first wavelength λg and the image data Ri of the second wavelength λr at the time i and the image data Gj and the second wavelength λr of the first wavelength λg at the time j are obtained. An operation is performed using a combination of four image data having different measurement wavelengths and measurement times from the image data Rj, and a set of image data is obtained by the operation.
Note that time i and time j are different times. For example, when time i is a certain measurement time, time j can be the next measurement time.

FIG. 4 schematically shows the relationship between the measured image data and the processed image data. The signal values G1, R1,
And signal values G2 and R2 at time t2 (4 surrounded by a solid line in the figure).

Hereinafter, similarly, calculation is performed using a combination of measured image data having different wavelengths and times to obtain processed image data D34, D45,.

575 nm (green) as the first wavelength λg
By using 600 nm (red) as the second wavelength λr, changes in oxyhemoglobin and deoxyhemoglobin can be obtained from the image data Gi and Ri. Oxyhemoglobin change [ΔOxyHb]
And the amount of change in deoxyhemoglobin [ΔdeOxyHb] are represented by the following equations using image data Gi, Gj, Ri, and Rj, respectively. [ΔOxyHb] = k1 (logGj−logGi) + k2 (logRj−logRi) (4) [ΔdeOxyHb] = k3 (logGj−logGi) + k4 (logRj−logRi) (5) where k1 to k4 are oxyhemoglobin It is a coefficient obtained from the spectrum of deoxyhemoglobin,
For example, k1 = −79, k2 = 212, k3 = 20, k4 =
-322 or the like.

The biological information such as the amount of change in oxyhemoglobin or deoxyhemoglobin obtained by the optical image measuring means 3 is
It indicates a change in blood flow in the peripheral circulation caused by the treatment device, and can be used as an index for judging the treatment effect. The control means 4 uses data such as the amount of change in oxyhemoglobin or deoxyhemoglobin obtained by the optical image measurement means 3 as an index of the therapeutic effect, and controls the intensity of the stimulating means and the treatment time based on the index.
