Description

  The present invention relates to a sensor fixture for attaching a biosensor to a quadruped animal in order to collect biological information such as body temperature from a quadruped animal such as livestock.

  In order to continuously acquire the body temperature of a quadruped animal, which is a mammal, and to grasp the transition of the state of the quadruped animal, for example, a measurement device equipped with a fixture that holds the temperature measuring unit inserted in the anus. Patent Documents 1, 2, and 3 disclose warming devices.

  For example, in Patent Document 1, in an animal body temperature measurement probe having a temperature sensor at the tip, an end-shaped annular rigid band fitted to the tail of the animal, and teeth on both ends of the band are disclosed. There is disclosed an animal body temperature measuring probe comprising a fixing tool including an engaging piece having the same.

  In Patent Document 3, in order to avoid the inconvenience of the tail being compressed by a fixture and to ensure safety, a temperature measuring unit on the distal end side is inserted from the anus of the animal into the intestine to measure the intestinal temperature. A sheath-type thermometer and a coil spring attached to the tail of the animal, and an end on the base side of the tail is connected to a predetermined position on the base end side of a region where the sheath-type thermometer is inserted An animal intestinal temperature measuring device including a coil spring has been proposed.

  Furthermore, in Patent Document 4, in the case of adopting a mode in which a body temperature sensor is inserted from the anus, in order to eliminate the disadvantage that the body temperature sensor is discharged together with the excrement when the animal gives out the excrement, An attachment device that enables stable body temperature measurement has been proposed.

  The fixture is a sensor that converts body temperature into an electrical resistance value, directly fixed to a part of the elastic belt, or an object to which the sensor is fixed is connected and fixed to the elastic belt, and the sensor is attached to the inner side of the front foot base and the abdomen. The telescopic belt is configured to be fixed using a part of the animal's foot, torso, neck, back, and chest in order to be installed in the sandwiched portion.

Japanese Utility Model Publication No. 07-3615 JP 2005-21418 A Japanese Patent No. 6164354 JP 2005-249765 A

  However, the fixture described in Patent Document 4 is limited to the case where a sensor that converts body temperature into an electrical resistance value is used, and when using a sensor for acquiring other biological information such as a heartbeat, the fitting is appropriate. In addition, there is a problem that it is necessary to attach a sensor to the measurement location and lack general versatility.

  Therefore, when we focused on the inside of the animal's tail as a part that is not discharged outside with the stool during excretion and is not easily affected by outside air, the inside of the tail is in contact with the body surface of the tail and is not easily affected by outside air. In addition to thin body hair, body temperature, heart rate, etc. can be detected continuously with high accuracy, but the position of the sensor is likely to shift when the tail is shaken, and because it is close to the anus, it is easily contaminated with feces during excretion. We have come up with a problem that it may be difficult to obtain accurate biological information.

  In view of the above problems, an object of the present invention is to provide a sensor attachment that can continuously measure biological information of a quadruped animal, is not easily contaminated with feces during excretion, and is easy to maintain even when it is dirty. .

  In order to achieve the above-mentioned object, the first characteristic configuration of the sensor fixture according to the present invention is a sensor fixture for attaching a biological information sensor to a quadruped walking animal as described in claim 1 of the claims. And a pulling portion constructed of a string-like or band-like annular body so as to be fitted into the tail of a quadruped walking animal, and pulling in the direction opposite to the tail so that the fitting does not leave the tail. A string-like or belt-like attachment part attached to the body of a quadruped walking animal, and the quadruped walking animal supported directly or indirectly by the insertion part and holding the biological information sensor on the base side of the tail And a sensor holding part wound around the tail.

  The biological information sensor is held on the base side of the tail by the sensor holding unit wound around the tail. A quadruped walking animal with a string-like or belt-like annular body inserted through the tail of the quadruped walking animal and pulled into the tail by a cord-like or belt-like attachment. The sensor holding part is directly or indirectly supported by the fitting insertion part. Therefore, even when the tail of a quadruped animal is swung around, the sensor holding part supported by the insertion part is stably kept wrapped around the tail. It will not get dirty.

  As described in claim 2, the second characteristic configuration is that, in addition to the first characteristic configuration described above, a part of the fitting insertion portion is formed of a water-impermeable material.

  If the insertion part is made of a non-permeable material, stool will be excreted from the anus and attached, or even if it is raining, the water of the stool will not infiltrate into the insertion part, such as cleaning Maintenance is easy.

  The third feature configuration is that, in addition to the first or second feature configuration described above, the sensor holding portion is made of a breathable material.

  If the sensor holding part is made of a breathable material, the attached tail can be kept in a good state without being steamed.

  In the fourth feature configuration, as described in claim 4, in addition to any of the first to third feature configurations described above, the attachment portion connected to the fitting insertion portion has a string shape or a belt shape. The elastic member is provided.

  Even if the posture of the quadruped walking animal may fluctuate due to walking or sitting, if the insertion part and the attachment part are connected via an elastic member, the insertion part is in the direction from the tail to the anti-tail Since the state pulled by is maintained, the insertion state is stably maintained without the insertion portion being detached from the tail portion.

  In the fifth feature configuration, in addition to any of the first to fourth feature configurations described above, the sensor holding portion is detachable directly or indirectly to the fitting insertion portion. It is in the point that is supported.

  Since the sensor holding part is detachably supported with respect to the insertion part, even if the biological information sensor fails and needs to be replaced, or the sensor holding part becomes dirty and needs to be replaced, Since only the sensor holding part needs to be removed from the insertion part, a large-scale operation such as removing the mounting part and the fitting insertion part becomes unnecessary.

  In the sixth feature configuration, in addition to any one of the first to fifth feature configurations described above, the annular body is formed to have a length of at least 40 cm. It is in.

  If the length of the annular body that is inserted into the tail is short, the fitting insertion part can be easily detached from the tail by the swinging up or turning operation of the tail, or the sensor can be displaced and the installation position of the sensor may be shifted. Is formed to a length of at least 40 cm (peripheral length of 80 cm or more), there is almost no possibility that the insertion portion is detached from the tail portion.

  In the seventh feature configuration, in addition to any one of the first to sixth feature configurations described above, a sheet-shaped sensor covering body that covers the outer surface of the sensor holding portion is provided. It is in the point to have.

  By covering the outer surface of the sensor holding part wound around the tail with the sheet-shaped sensor covering, feces during defecation are protected by the sensor covering without adhering to the sensor holding part.

  In the eighth feature, as described in claim 8, in addition to the seventh feature described above, the outer surface of the sensor cover is made of a water-impermeable material.

  If the outer surface of the sensor cover is made of a non-permeable material, stool is excreted and adhered from the anus, or even if it is raining, moisture infiltrates the sensor cover and soils the sensor cover. This can be avoided.

  In the ninth feature configuration, as described in claim 9, in addition to the seventh or eighth feature configuration described above, the sensor covering body is a part of the tail while covering the sensor holding portion. Is provided with a fixing portion that is fixed to be open to the outside air.

  If the sensor holding part wrapped around the tail is covered with the sensor cover and fixed with the fixing part, and a part of the tail is open to the outside air, the condition of the skin surface can be maintained without the tail becoming muddy. .

  In the tenth feature configuration, in addition to any one of the seventh to ninth feature configurations described above, the first sensor cover is detachably attached to the fitting insertion portion. There exists an attachment member and the 2nd attachment member which attaches the said sensor holding | maintenance part to the said sensor covering body so that attachment or detachment is possible.

  When the sensor cover attached to the insertion portion via the first attachment member is removed from the insertion portion, it can be removed integrally with the sensor holding portion attached to the sensor cover via the second attachment member. The operability of maintenance work such as cleaning and parts replacement is extremely good.

  In the eleventh characteristic configuration, in addition to any of the seventh to tenth characteristic configurations described above, the sensor covering body has at least 10 cm in the longitudinal direction of the tail. It is in the point formed in length.

  If the length in the direction along the longitudinal direction of the tail of the sensor covering is 10 cm or more, the sensor holding part can be sufficiently protected even when a large amount of excreted feces adheres, and further the tail Or since it becomes a contact area which can obtain sufficient frictional force with a sensor holding part, even if a tail is swung up or turned, it can avoid that it shifts or separates.

  In the twelfth characteristic configuration, as described in claim 12, in addition to any of the seventh to eleventh characteristic configurations described above, irregularities are formed on the inner surface of the sensor covering body. In the point.

  The unevenness formed on the inner surface of the sensor cover ensures air permeability between the skin surface of the tail and avoids adverse effects due to stuffiness.

  The thirteenth feature configuration includes a temperature sensor and a heart rate sensor in the biological information sensor, in addition to any one of the first to twelfth feature configurations described above, as described in claim 13. The sensor holding unit includes a first storage unit that holds the temperature sensor on the base side of the tail, and a second storage unit that holds the heart rate sensor on the tip side of the tail from the temperature sensor.

  When a temperature sensor and a heart rate sensor are used as the biological information sensor, an accurate body temperature can be measured by holding the temperature sensor at a site with little body hair on the base side of the tail close to the torso by the first housing part. If the heart rate sensor is held on the distal end side of the tail from the temperature sensor by the two housing units, the heart rate can be measured sufficiently.

  In addition to any one of the first to thirteenth feature configurations described above, the fourteenth feature configuration receives a signal from the biological information sensor and transmits the signal to the outside. The signal processing unit to be mounted is attached at any point between the fitting portion and the mounting portion.

  Since the detection value by the biological information sensor can be taken out via the signal processing unit, the biological information can be continuously obtained without human intervention.

  As described above, according to the present invention, it is possible to provide a sensor attachment that can continuously measure biological information of a quadruped walking animal, is not easily contaminated with feces during excretion, and can be easily maintained even when it is dirty.

Hereinafter, a sensor fixture to which the present invention is applied will be described with reference to the drawings.
1 (a) and 1 (b) show a sensor attachment 100 attached to a cow, which is an example of a quadruped walking animal. The sensor fixture 100 is used to attach a biological information sensor for collecting biological information of a quadruped animal such as body temperature and pulse to the body surface of the quadruped animal.

  In the following, the structure of the sensor attachment 100 will be described in detail by taking a cow as an example of a quadruped walking animal. However, the sensor attachment 100 can be attached not only to a cow but also to a bull, and the size is adjusted. Therefore, it can be worn on quadruped mammals other than cattle, such as horses and camels, and can be worn on pets such as dogs.

  As shown in FIGS. 1 (a), 1 (b) and FIGS. 4 (a), 4 (b), the sensor attachment 100 includes a belt-like annular body 11 that is inserted into the tail 3 through the tail 2 of the cow 1. A band-shaped mounting portion 20 to be mounted on the body of the cow 1 in a state of being pulled in the anti-tail portion direction, that is, the direction toward the neck portion 4 so that the insertion insertion portion 10 is not detached from the tail portion 3; A sensor holding unit 30 that is supported directly or indirectly by the fitting insertion unit 10 and is wound around the tail 2 so as to hold the biological information sensor on the base side of the tail, and a sensor covering body 40 that covers the sensor holding unit 30. I have.

  A signal processing unit 50 that receives a signal from the biological information sensor and transmits the signal from the biological information sensor to the outside is detachably attached between the insertion unit 10 and the mounting unit 20, and a signal is transmitted between the biological information sensor and the signal processing unit 50. A line is arranged.

  The signal processing unit 50 includes a timing circuit, a signal processing circuit that receives an output signal of the biological information sensor and generates biological information, a storage circuit that stores biological information generated by the signal processing circuit, and a storage circuit A communication circuit that wirelessly transmits stored biometric information to the outside, a battery that supplies power to each circuit block, and the like are provided.

  Zigbee adopting “IEEE 802.15.4” is used as a wireless communication standard adopted for communication circuits. In large-scale facilities that keep a large number of animals, Zigbee is suitable because it has a large breeding area and a large number of individuals, so it has a long communication distance, a sufficient number of connected nodes, and a long battery life of several years. . It is also possible to use Bluetooth (Blue tooth is a registered trademark) adopting the wireless communication standard “IEEE 802.15.1”, Wi-Fi adopting the wireless communication standard “IEEE 802.11”, or the like.

  Since the detection value by the biological information sensor can be taken out via the signal processing unit 50, the biological information can be continuously obtained without human intervention. For example, the trend data indicating the transition of the sampled biological information is output at a predetermined time, the trend data before and after it is output when the biological information shows an abnormal value different from normal, The biometric information or the average value of the biometric information can be output. It is also possible to output sampled biological information in response to a request from an external device.

  An acceleration sensor that detects the movement of the cow 1 may be incorporated in the signal processing unit 50 and used in combination with a biological information sensor provided on the tail. In this case, although depending on the purpose of the measurement using the acceleration sensor, it is preferable that the signal processing unit 50 is mounted at a position that is 20 cm or more away from the tail portion that is not easily affected by the shake of the tail portion 3.

  The insertion portion 10 includes an annular body 11 and a cord-like body 13 having one end joined to the annular body 11 and the other end connected to the mounting portion 20 via a connector 15. Reference numeral 13 is a non-stretchable belt-like thick fabric.

  The other end side of the cord-like body 13 is folded back to one end side by a connecting tool 15 and fixed by a locking tool 14 so as to be adjustable in length. When the locking tool 14 is loosened to increase the overlapping length of the cord-like body 13, the cord-like body 13 is shortened, and when the overlapping length is reduced, the cord-like body 13 is lengthened.

  Although it depends on the length of the annular body 11, the non-water-permeable structure is formed on the opposite side of the annular body 11 from the joint portion of the cord-like body 13 over a length of about ¼ to 1/2 of the length of the annular body 11. A covering portion 12 is provided in which the fabric is covered with a conductive material. A cushion member is interposed between the non-stretchable fabric and the covering portion 12 so that the skin surface is not scratched when attached to the tail portion 3. Since the coating | coated part 12 is comprised with the water-impermeable material, the water | moisture content of the feces excreted from the cow 1 does not impregnate, and can be cleaned easily.

  The length of the annular body 11 is preferably configured to be at least 40 cm. The length of the annular body 11 means a length obtained by folding the annular body 11 in half, and the upper limit is not particularly limited, but is determined by the physical condition of the animal to be applied. For example, in the case of a cow, 80 cm to 100 cm is acceptable. If the length of the annular body 11 to be inserted into the tail portion 3 is short, the insertion portion 10 may be easily detached from the tail portion 3 due to the swinging or turning operation of the tail 2, but the annular body 11 is at least 40 cm. When it is formed in the above length, there is almost no possibility that the insertion portion is detached from the tail portion.

  The mounting portion 20 is composed of a non-stretchable belt-like thick fabric, a cord-like body 22 that hangs down from the back portion 6 of the cow 1 to the trunk portion 7, and a connector 26 on the distal end side of the cord-like body 22. And the elastic belt 21 having one end connected to the cable-like body 13 via the connector 15 and the other end connected to the cable-like body 22 via the connector 27 such as a cannabis hook. It is prepared for.

  The cord-like body 22 is provided with retaining rings 25a and 25b for locking at two places along the extending direction. After the left and right elastic belts 23 are wound around the left and right front legs 5 of the cow 1, respectively, The cannula hook 24 provided at the tip of the elastic belt 23 is hung on the retaining rings 25a and 25b (see FIGS. 1B and 4B).

  The insertion part 10 is pulled toward the neck 4 of the cow 1 by an elastic belt 21 so that the insertion part 10 does not loosen and separate from the tail part 3 with various movements of the cow 1. In this state, the pair of left and right cords 22 and the elastic belt 23 are hooked and fixed to the front legs 5.

  The cord-like bodies 13 and 22 and the annular body 11 constituting the fitting insertion portion 10 and the mounting portion 20 are constituted by flat strips having a width in the range of 30 mm to 50 mm. The cord-like bodies 13 and 22 are not limited to the band-like bodies, and may be constituted by string-like bodies.

  FIG. 2A shows the external appearance of the sensor holding unit 30. The sensor holding unit 30 includes a base material 31 formed in a horizontally long rectangular shape with a thick fabric or knitted fabric having stretchability and air permeability, a biological information sensor housing portion 32 provided on the base material 31, and a sensor coating A second attachment member 33 for detachably attaching the sensor holding part 30 to the body 40 and a fixing part 34 for fixing the base material 31 wound around the tail 2 of the cow 1 are provided.

  The base material 31 may be made of a fabric woven or knitted using, for example, a filament yarn such as polyester fiber and a urethane yarn so as to have quick drying, breathability, and stretchability. If the sensor holding part 30 is comprised with the air permeable material, the mounted | wearing tail 2 can maintain the favorable state of the skin surface, without being steamed.

  Two biological information sensor accommodating portions 32 are provided in the vertical direction of the central portion of the base material 31, and are configured to accommodate two types of biological information sensors. As the biological information sensor, a temperature sensor and a heart rate sensor are preferably used, the temperature sensor is held in the first housing portion 32a, and the heart rate sensor is held in the second housing portion 32b. A thermistor or a thermocouple is preferably used as the temperature sensor, and a reflection type optical sensor that detects a blood flow that pulsates with light is preferably used as the heart rate sensor. However, the present invention is not limited to this type of sensor.

  The sensor holding part 30 is wound around the tail 2 so that the biological information sensor accommodating part 32 is positioned on the inner skin of the tail 2. In this state, the temperature sensor is located on the base side of the tail 2, and the heart rate sensor is located on the distal end side of the tail from the temperature sensor. An accurate body temperature can be measured by holding the temperature sensor at a portion of the base side of the tail 2 near the trunk where there is little body hair by the first accommodating part 32a, and the tail 2 of the tail 2 can be measured by the second accommodating part 32b. If the heart rate sensor is held on the tip side, the heart rate can be measured sufficiently.

  The biological information sensor housed in the biological information sensor housing unit 32 is not limited to a temperature sensor or a heart rate sensor, and other sensors that can acquire biological information can also be used. In addition to biometric information sensors, it houses sensors that detect movements such as accelerometers to detect walking, sitting, and tail swinging of cows, and humidity sensors that detect the environment near the skin. It is also possible to do.

  A pair of non-stretchable strips 33 serving as the second mounting member 33 is provided on the upper side of the base material 31 so as to sandwich the biological information sensor housing 32, and a pair of hook-and-loop fasteners 33 a and 33 b are provided at both ends of the strip 33. Is provided. A large number of loops serving as locking portions are vegetated on the hook-and-loop fastener 33a, and a large number of hooks serving as engaging portions are vegetated on the hook-and-loop fastener 33b.

  Similarly, in the base material 31, a pair of surfaces serving as the fixing portions 34 are provided at one end in the longitudinal direction of the surface on which the biological information sensor accommodating portion 32 is provided and the other end in the longitudinal direction of the opposite surface. Fasteners 34a and 34b are provided.

  As shown in FIG. 2 (b), the sensor cover 40 includes an inverted trapezoidal sheet member 41 that is used to cover the outer surface of the sensor holding unit 30, and an annular shape of the fitting insertion unit 10 that has the sheet member 41 described above. A first attachment member 42 detachably attached to the body 11, a pair of insertion portions 43 for holding the sensor holding portion 30 described above, and a tail portion 2 covering the outer surface of the sensor holding portion 30 wound around the tail 2. A fixing portion 44 is provided to be fixed to.

  The sheet member 41 is composed of a breathable member having an outer surface made of a water-impermeable material and an inner surface having an uneven surface. As the non-water-permeable material, for example, a non-stretchable cloth having a water-repellent property coated with a urethane resin on the surface and woven with synthetic fiber yarn is used. As the breathable member, a urethane foam sheet having a thickness of several millimeters and having an appropriate cushioning property is used. Both are lightweight and do not put great stress on the animals they are wearing.

  Since the outer surface is made of a water-impermeable material, stool is excreted and adhered, or even if it is raining, moisture infiltrates inside the sensor cover 40 and soils the sensor holding unit 30. There is nothing. Further, since the inner surface is formed with irregularities, air permeability between the tail 2 and the skin surface is ensured, and adverse effects due to stuffiness can be avoided.

  If an oil such as beef tallow or lard is attached to the surface of the water-impermeable material used for the covering portion 12 or the sensor covering body 40, it is difficult to get dirt, and maintenance work such as cleaning when dirty becomes easy.

  Three strips 44a, 44b, 44c distributed in the vertical direction are provided as the fixing portion 44, and a plurality of hooks serving as engaging portions are vegetated at the tips of the strips 44a, 44b, 44c. A fastener 47 is provided. Furthermore, a hook-and-loop fastener 48 is provided on the back surface of the sheet member 41 in a vertically long posture, and a large number of loops serving as locking portions are vegetated.

  As shown in FIG. 3A, the pair of belt-like portions 33 serving as the second attachment members 33 provided in the sensor holding portion 30 described above are inserted into the insertion portions 43 and folded, whereby the hook-and-loop fasteners 33a and 33b are formed. The sensor holding part 30 is fixed to the sensor cover 40 by engaging.

  As shown in FIGS. 3A and 3B, the first attachment member 42 is formed of a non-stretchable belt-like body, and a pair of hook-and-loop fasteners 42a and 42b are provided on the upper end side and the lower end side. By winding and folding the first attachment member 42 around the covering portion 12 provided in the annular body 11, the hook-and-loop fasteners 42 a and 42 b are engaged and the sensor covering body 40 is fixed to the fitting insertion portion 10. In FIG. 3B, the sensor holding unit 30 is not drawn, but actually, the sensor holding unit 30 is disposed inside the sensor cover 40.

  As shown in FIGS. 5A and 5B, the fixing portion 44 is a sheet member that is formed with an opening portion 49 in which a part of the tail 2 is opened to the outside air in a state where the sensor holding portion 30 is covered. 41 can be fixed to the tail 2. Accordingly, in a state where the tail 2 is fixed, a part of the tail 2 is released to the outside air, and the tail 2 is kept in a good state without being steamed.

  As described above, the outer surface of the sensor holding unit 30 wound around the tail 2 is covered with the sheet-like sensor coating 40, so that feces during defecation do not adhere to the sensor holding unit 30. Protected by.

  The inverted trapezoidal sheet member 41 constituting the sensor covering 40 is preferably formed in a length of at least 10 cm in the longitudinal direction of the tail 2, and is further formed in a length of 15 cm or more. preferable.

  If formed in such a length, the sensor holding part 30 can be sufficiently protected even when a large amount of excreted feces adheres, and furthermore, the tail 2 or the sensor holding part 30 and a sufficient frictional force. Therefore, even if the tail 2 is swung up or turned, it is possible to avoid displacement or separation. The upper limit of the length is not particularly limited, but is limited to about 20 cm to 30 cm so that the movable range of the tail 2 is limited and the cow 1 is not stressed.

  The shape of the sheet member 41 constituting the sensor cover 40 is not limited to the inverted trapezoidal shape, but can be fixed to the tail 2 by covering the outer surface of the sensor holding part 30 wound around the tail 2 such as a rectangular shape. Any shape can be used.

  As described above, the sensor holder has an insertion part formed of a string-like or band-like annular body so as to be inserted into the tail part of a quadruped walking animal, and the insertion part is not detached from the tail part. It is supported directly or indirectly by a strap-like or belt-like attachment part that is pulled in the direction of the anti-tail part and attached to the body of a quadruped walking animal, and the biological information sensor is held on the base side of the tail And a sensor holding part wound around the tail of the quadruped walking animal.

  Therefore, even when the tail of a quadruped animal is swung around, the sensor holding part supported by the insertion part is stably kept wrapped around the tail. There is no dirt or damage.

  In the above-described embodiment, an example in which the first attachment member 42 that detachably attaches the sensor cover 40 to the fitting portion 10 and the second attachment member 33 that attaches the sensor holding portion 30 to the sensor cover 40 detachably is provided. However, the sensor holding portion 30 may be configured to be directly supported by the fitting insertion portion 10 in a detachable manner.

  As a specific configuration of each mounting member, a snap button, a cannula hook, a resin-made locking tool, or the like can be used as appropriate in addition to the above-described hook-and-loop fastener.

  As described above, the sensor cover 40 is detachably attached to the insertion portion 10, so that the biological information sensor may need to be replaced due to failure, or the sensor holding portion may need to be replaced due to contamination. However, since only the sensor holding body 40 to which the sensor holding portion or the sensor holding portion is attached needs to be removed from the insertion portion, a large-scale operation for removing the mounting portion 20 and the insertion portion 10 is not necessary.

  Each of the embodiments described above is merely an example of the present invention, and the present invention is not limited by the description.Specific configurations such as the material and shape size of each part constituting the sensor fixture are as follows. Needless to say, the design can be changed as appropriate within the range where the effects of the present invention are exhibited.
