[conditions]
Using a tensile tester, the center of the belt-shaped fabric is placed in the center between the chucks, and the belt-shaped fabric is clamped so that the distance between the chucks is 50 mm, and the strip is stretched at a tensile speed of 100 mm/min.

The first garment and the second garment are the same in that they have a base fabric arranged around the torso and a stretch sensor, and the second garment further has a belt-like shape arranged around the torso. It has fabric. On the other hand, in the first clothing and the second clothing, the stretch sensor in the first clothing is provided in the base fabric, while the stretch sensor in the second clothing is provided in the belt-shaped fabric. There is a difference.

First, the first clothing will be explained. The first garment has a base fabric arranged around the torso and a stretch sensor, the stretch sensor being provided on the base fabric.

The base fabric is the fabric that makes up the clothing worn by the quadruped and is placed around the torso of the quadruped. Torso circumference means the circumference of the torso, including the back and abdomen of a quadruped. The base fabric in the lengthwise direction of the quadruped may, for example, cover the area from the withers to the waist. The base fabric may also cover the prothorax of the tetrapod.

Materials for the base fabric include knitted fabrics, woven fabrics, and non-woven fabrics. Of these, knitted fabrics are preferred because of their excellent stretchability. Knitted fabrics include weft knitted fabrics or warp knitted fabrics. The weft knitted fabric includes a circular knitted fabric. Weft knitted fabrics (circular knitted fabrics) include, for example, jersey knitting (flat knitting), bare jersey knitting, welted jersey knitting, milling knitting (rubber knitting), pearl knitting, single bag knitting, smooth knitting, tuck knitting, float knitting, and single knitting. Examples include hem knitting, lace knitting, and additional hair knitting. Examples of warp knitted fabrics include single denby knitting, open denby knitting, single atlas knitting, double cord knitting, half knitting, half base knitting, satin knitting, single tricot knitting, double tricot knitting, half tricot knitting, single Russell knitting, Examples include double Russell knitting and jacquard knitting. Examples of woven fabrics include woven fabrics formed by plain weave, twill weave, satin weave, and the like. Moreover, the woven fabric is not limited to a single woven fabric, and may be a multiple woven fabric such as a double woven fabric or a triple woven fabric. Note that the base fabric may be formed in a mesh shape.

Knitted fabrics and woven fabrics preferably contain at least one type of fiber selected from the group consisting of natural fibers, synthetic fibers, regenerated fibers, and semi-synthetic fibers. Natural fibers include, for example, cotton, hemp, wool, and silk. Among these, cotton is preferred. Moisture absorption, water absorption, heat retention, etc. are improved by including cotton. The natural fibers may be used as they are, or may be subjected to post-processing such as hydrophilic treatment and antifouling treatment. Examples of synthetic fibers include acrylic; polyesters such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene isophthalate, polylactic acid, and polyacrylate; polyamides such as nylon 6 and nylon 66; be done. Examples of regenerated fibers include rayon such as modal, cupra, polynosic, and lyocell. Examples of semi-synthetic fibers include acetate, triacetate, and the like. These may use only 1 type, and may use 2 or more types.

The extension sensor is a sensor that can detect the degree of extension and contraction, and is not particularly limited as long as it is a sensor that can measure changes in the chest circumference based on respiration of the quadruped animal by extension and retraction. . The stretch sensor includes, for example, a stretchable capacitor. A stretchable capacitor is an element whose capacitance changes due to expansion and contraction, and the change in the capacitance can be used to measure the respiratory state of a quadruped animal. The expansion/contraction sensor preferably has at least a capacitor element whose capacitance changes due to expansion and contraction, and a skin contact electrode. The capacitor element whose capacitance changes due to expansion and contraction is a capacitor-type element having at least a structure in which at least a first stretchable conductor layer, an stretchable dielectric layer, and a second stretchable conductor layer are laminated in this order. is preferred. The skin contact surface of the skin contact electrode is preferably an elastic conductor layer. For details of the expansion/contraction sensor, for example, reference can be made to Japanese Patent Application Laid-Open No. 2019-072048.

In the first garment, a stretch sensor is provided on the base fabric, and the stretch sensor is arranged so as to be able to detect the stretch in the direction around the trunk of the tetrapod, thereby measuring the degree of stretch around the trunk based on the respiration of the tetrapod. can be detected.

In the first garment, it is important that the base fabric with the stretch sensor has a tensile strength of 0.3 N/cm or more and 3.0 N/cm or less when stretched 20% in the direction around the torso. By setting the tensile strength at 20% elongation to 0.3 N/cm or more, the stretch sensor can be fixed at a desired position of the quadruped animal, so that the measurement accuracy can be improved. Therefore, the tensile strength at 20% elongation is 0.3 N/cm or more, preferably 0.5 N/cm or more, more preferably 1.0 N/cm or more. However, if the tensile strength at 20% elongation exceeds 3.0 N/cm, the base fabric is difficult to stretch, so the stretch sensor is also difficult to stretch, resulting in poor measurement accuracy. Therefore, the tensile strength at 20% elongation is 3.0 N/cm or less, preferably 2.5 N/cm or less, more preferably 2.0 N/cm or less.

The tensile strength at 20% elongation in the direction around the body was measured by placing the center of the test piece made of the base fabric in the center between the chucks of the tensile tester and chucking the test piece so that the distance between the chucks was 50 mm. It can be measured by pinching and elongating at a tensile speed of 100 mm/min.

The ratio of the area covered with the base fabric to the body surface area of the quadruped is, for example, preferably 30% or more, more preferably 40% or more, and even more preferably 50% or more. The upper limit of the ratio of the area covered with the base fabric is, for example, preferably 70% or less, more preferably 65% or less, still more preferably 60% or less.

The base fabric preferably has electrodes on the side of the skin. By having electrodes on the lateral side of the skin, it is also possible to measure temporal fluctuations in the heart rate as biological information of the tetrapod.

The position where the electrodes are placed should be close to the heart of the tetrapod. For example, it is preferable to place the electrodes on the side of the skin of the base fabric that covers the anterior chest when worn by the tetrapod.

The stretch sensor may be fixed to the base fabric, but it is preferably removable. By making it detachable, the base fabric can be washed with the expansion/contraction sensor removed. In addition, since the stretch sensor is detachable, the stretch sensor can be used in common even if the wearer has a plurality of clothes. The expansion/contraction sensor can be detachable using, for example, hook-and-loop fasteners such as Velcro (registered trademark) and Free Velcro (registered trademark).

Next, the second clothing will be explained. The second garment has a base fabric arranged around the torso, a strip-shaped fabric arranged around the torso, and a stretch sensor, and the stretch sensor is provided on the strip-shaped fabric.

The base fabric, like the first clothing, is a fabric that constitutes the clothing worn by the tetrapod, and is arranged around the body of the tetrapod.

For the description of the stretch sensor used in the second clothing, refer to the description of the stretch sensor used in the first clothing.

The belt-shaped fabric is a separate member from the base fabric, and is a circular fabric that is arranged around the body of the tetrapod. Torso circumference means the circumference of the torso, including the back and abdomen of a quadruped. The width of the belt-shaped fabric is preferably 5% or more, more preferably 10% or more, still more preferably 15% or more and 30% or less with respect to the width of the base fabric in the body length direction of the tetrapod. is preferably 25% or less, and still more preferably 20% or less.

The strip-shaped fabric may be partially or entirely laminated on the base fabric. For example, when part of the strip-shaped fabric is laminated on the base fabric, both ends of the strip-shaped fabric are laminated on the base fabric. A configuration example is given.

For the material of the strip-shaped fabric, the material of the base fabric can be referred to, and the material of the strip-shaped fabric may be the same as or different from the material of the base fabric. Also, the belt-like fabric may be formed in a mesh shape.

In the second garment, a stretch sensor is provided on the belt-shaped fabric, and by arranging the stretch sensor so as to be able to detect the stretch in the direction around the trunk of the quadruped animal, the degree of stretch around the trunk based on the respiration of the quadruped animal can be measured. can be detected. For the description of the stretch sensor, the description of the first garment can be referred to.

In the second garment, it is important that the belt-shaped fabric provided with the stretch sensor has a tensile strength of 0.3 N/cm or more and 3.0 N/cm or less when stretched 20% in the direction around the torso. By setting the tensile strength at 20% elongation to 0.3 N/cm or more, the stretch sensor can be fixed at a desired position of the quadruped animal, so that the measurement accuracy can be improved. Therefore, the tensile strength at 20% elongation is 0.3 N/cm or more, preferably 0.5 N/cm or more, more preferably 1.0 N/cm or more. However, if the tensile strength at 20% elongation exceeds 3.0 N/cm, the belt-shaped fabric is difficult to stretch, so the stretch sensor also becomes difficult to stretch, resulting in poor measurement accuracy. Therefore, the tensile strength at 20% elongation is 3.0 N/cm or less, preferably 2.5 N/cm or less, more preferably 2.0 N/cm or less.

The tensile strength at 20% elongation in the direction around the body was measured by placing the center of a strip-shaped fabric test piece in the center between chucks using a tensile tester, and placing the test piece so that the distance between chucks was 50 mm. It can be measured by pinching with a chuck and elongating at a tensile speed of 100 mm/min.

The tensile strength at 20% elongation in the direction around the torso of the base fabric in the second clothing is not particularly limited, and the tensile strength at 20% elongation may be less than 0.3 N/cm. Although it may exceed 0 N/cm, it preferably satisfies the range of 0.3 N/cm or more and 3.0 N/cm or less. If the tensile strength at 20% elongation in the direction around the torso of the base fabric satisfies the range of 0.3 N / cm or more and 3.0 N / cm or less, the tensile strength at 20% elongation in the direction around the torso of the base fabric The strength and the tensile strength at 20% elongation of the belt-like fabric may be different or the same, and are preferably the same. By being the same, there is no difference in the degree of expansion and contraction between the belt-shaped fabric and the base fabric, so the measurement accuracy can be improved.

The stretch sensor may be fixed to the belt-shaped fabric, but it is preferably removable. By making it detachable, it is possible to wash the belt-like fabric with the expansion/contraction sensor removed. In addition, since the stretch sensor is detachable, the stretch sensor can be used in common even if the wearer has a plurality of clothes. The expansion/contraction sensor can be detachable using, for example, hook-and-loop fasteners such as Velcro (registered trademark) and Free Velcro (registered trademark).

The belt-shaped fabric may be fixed to the base fabric, but it is preferably removable. By making it detachable, the belt-like fabric and the base fabric can be washed separately. In addition, since the belt-like fabric is detachable, the belt-like fabric and clothing can be used in any combination. The belt-like fabric can be made removable using, for example, hook-and-loop fasteners such as Velcro (registered trademark) and Free Velcro (registered trademark), buckles, hooks, buttons, and the like.

Tetrapods are amphibians, reptiles, or mammals, with mammals being preferred. Examples of mammals other than humans include dogs, cats, cows, horses, and pigs, preferably dogs, cats, or cows.

The present invention also includes a clothing-type biological information measuring device for quadrupeds. The clothing-type biological information measuring device for quadrupeds according to the present invention transmits the biological information measuring clothing (that is, the first clothing or the second clothing) and the data detected by the stretch sensor to a receiver. The present invention is characterized in that it has a transmitter that transmits data, a receiver that receives data transmitted from the transmitter, and a computing unit that computes the data received by the receiver.

It is preferable that the extension sensor is electrically connected to the transmitter by wiring or the like. On the other hand, it is preferable that the transmitter and the receiver are wirelessly connected.

The transmitter is preferably provided on the base fabric in the first garment, and preferably provided on the belt-shaped fabric in the second garment. On the other hand, the receiver and the arithmetic unit may be provided on the base fabric or the belt-like fabric, but preferably they are not provided on the base fabric or the belt-like fabric and are separately provided. By separating them, the weight of the clothing-type biological information measuring device can be reduced, so that the load on the quadrupeds can be reduced.

It is preferable that the calculation unit detects whether abnormal respiration has occurred in the quadruped animal based on the data detected by the extension sensor.

　As a calculation unit, for example, at least a central processing unit (CPU) or the like may be provided. It is also preferable to have a storage unit (for example, memory) for storing ecological information data obtained from the quadruped.

It is also preferable that the clothing-type biological information measuring device for quadrupeds further includes electrodes arranged on the side of the skin of the base fabric. By having electrodes arranged on the side of the skin of the base fabric, it is also possible to measure temporal fluctuations in the heart rate as biological information of the quadruped animal.

Examples of the abnormal breathing detection method for quadrupeds according to the present invention include the following three methods.

That is, the first detection method is a time-varying waveform of the depth of breathing, which continuously has a maximum value indicating a turning point from inspiration to expiration and a minimum value indicating a turning point from expiration to inspiration. a step of acquiring a waveform from a quadruped animal (hereinafter sometimes referred to as a measurement respiratory waveform acquisition step), and a time at which the waveform has a maximum value T ₁ , T ₂ , . . . , T _i , . . . , T _n , where n is a natural number of 3 or more, a step of continuously calculating the time difference (T _i −T _i−1 ) for a plurality of locations (hereinafter sometimes referred to as a time difference calculation step); If the difference between the time difference (T _i -T _i-1 ) and the time difference (T _i-1 -T _i-2 ) is 1 second or more, the step of detecting that abnormal breathing has occurred (hereinafter referred to as the first (sometimes referred to as an abnormal respiration detection step).

The second detection method is a time-varying waveform of the depth of breathing, which continuously has a maximum value indicating a turning point from inspiration to expiration and a minimum value indicating a turning point from expiration to inspiration. a step of acquiring a waveform from a quadruped animal (measured respiratory waveform acquisition step) _; and T ₁ , _T ₂ , . When the natural number is 3 or more, a step of continuously calculating the time difference (T _i −T _i-1 ) for a plurality of locations (time difference calculation step), and a step of calculating the average value of the calculated time differences (hereinafter referred to as the average value calculation step), the calculated average value of the time difference, and the time difference (T _i −T _i-1 ), if the difference is 0.8 seconds or more, it is detected that abnormal respiration has occurred. step (hereinafter sometimes referred to as a second abnormal breathing detection step).

The third detection method is a time-varying waveform of the depth of breathing, which has a maximum value indicating a turning point from inspiration to expiration and a minimum value indicating a turning point from expiration to inspiration in succession. a step of acquiring a waveform from a quadruped animal (measured respiratory waveform acquisition step) _; and T ₁ , _T ₂ , .

The first detection method to the third detection method are identical in that they have a measured respiratory waveform acquisition step, a time difference calculation step, and an abnormal _breathing detection step. T _i-1 ) and the time difference (T _i-1 −T _i-2 ) to determine whether abnormal breathing has occurred. Based on the difference between (T _i -T _i _- ₁ ), it is determined whether abnormal breathing has occurred. ) is different in that it is determined whether or not abnormal respiration has occurred based on the rate of decrease in the value of .

Each detection method will be explained below.

[First detection method]
(Measured respiratory waveform acquisition step)
In the measured respiration waveform acquisition step, a temporal variation waveform of respiration depth (hereinafter sometimes referred to as a measured respiration wave) is acquired from the quadruped animal. The measured respiratory wave has successive maxima and minima, the maxima indicating the turning point from inspiration (inhalation) to expiration (exhalation), and the minima from expiration (exhalation) to inspiration (inhalation). It shows the turning point to

(Time difference calculation step)
In the time difference calculating step, when the times T ₁ , T ₂ , . . . , _T _i , . The time difference (T _i -T _i-1 ) between the time T i at which the respiratory wave reaches its maximum value and the time T _i _-1 at which the measured respiratory wave reaches its maximum value is continuously calculated for a plurality of points. do. The number of times the time difference is measured is not particularly limited, and is preferably 2 or more, more preferably 3 or more, and the upper limit is preferably 5 or less, more preferably 4 or less.

A procedure for measuring the difference (T _i -T _i-1 ) between time T _i and time T _i-1 will be described with reference to the drawings. In FIG. 1, curve 1 indicated by a solid line indicates the measured respiratory waveform obtained from a _quadruped animal. _i-1 , and the difference between the time T i at which the measured respiratory waveform reaches its maximum value and the time T _i _-1 is the time difference (T _i -T _i-1 ). In FIG. 1, the horizontal axis indicates time, and the vertical axis indicates the depth of breathing.

The present invention focuses on the time at which the measured respiratory waveform reaches its maximum value, not the time at which the measured respiratory waveform reaches its minimum value. By measuring the time difference at the position where the measured respiration waveform has the maximum value, the measurement accuracy is higher than measuring the time difference at the position where the minimum value t is obtained.

(First abnormal respiration detection step)
In the first abnormal breathing detection step, the difference between the time difference (T _i -T _i-1 ) calculated in the time difference calculation step and the time difference (T _i-1 -T _i-2 ) is calculated. Seconds or more (preferably 1.2 seconds or more, more preferably 1.5 seconds or more) is detected as occurrence of abnormal respiration. By making a judgment based on the difference between the time difference (T _i -T _i-1 ) and the time difference (T _i-1 -T _i-2 ), like the second detection method and the third detection method described later, The presence or absence of abnormal respiration can be easily detected without calculating the average value.

For example, any one of coughing, sneezing, belching, vomiting, and spitting can be detected as abnormal respiration.

[Second detection method]
(Measured respiratory waveform acquisition step)
