Abstract: The present disclosure provides, for example, a fitting implement that reduces stress on an animal. A fitting implement is to be worn by an animal and includes: a collar section to be fitted around a neck of the animal; and a first belt section and a second belt section each having an end connected to the collar section, wherein the first and second belt sections each include, at another end thereof, a connecting section configured to connect the other ends together.

Abstract: Provided are a wearable instrument and other things capable of setting suitable tightness. A wearable device includes the following: a collar; a belt having one end connected to the collar, and extending to the animal's back via a dog's armpit when the wearable device is attached to the dog; and a joint where the belt length is adjusted. The belt has a wearable-device index indicated for the length adjustment with the joint, the wearable-device index corresponding to a measuring-instrument index indicated on an index belt included in a measuring instrument.

Abstract: A body surface temperature measurement device capable of appropriately performing measurement of a body surface temperature of an animal is realized. A body surface temperature measurement device includes a temperature sensing unit including an infrared ray detection sensor and a cover that covers the infrared ray detection sensor, in which the cover closely contacts a body surface of the animal and at least a part of a contact surface of the cover, which contacts the body surface of the animal, is formed into a curved surface that bulges toward a body surface side of the animal.

Abstract: In order to increase the chances of acquiring biological information from a haired living organism, an electrode instrument includes: a belt configured to fit the electrode instrument to a living organism; a projection projecting from the belt; and an electrically conductive cloth disposed on a surface of the projection or in a vicinity thereof to function as a part of an electrode.

Abstract: An easy-to-fit measuring instrument is provided. A measuring instrument (10) includes: a main wearable unit (1) to be fitted either to a neck of an animal on which measurement is to be made or close to the neck; and an electrode belt (5) including an electrode (6) to be fitted, for measurement of biological information, in such a manner that the electrode is in contact with at least either one of left and right axillae of the animal, wherein the electrode belt has a first end that is connected to the main wearable unit and a second end that is to be connected to the main wearable unit in a location that is closer to a back of the animal than the first end is close to the back of the animal.

Abstract: A state acquisition computer is provided that includes an interface configured to acquire data for indicating an inter-beat interval of an animal, and a processor configured to convert a Poincare plot of inter-beat intervals into a prescribed coordinate system, and based on a standard deviation of the Poincare plot after conversion, acquire information indicating a psychological state or a physical state of the animal.

Abstract: Computers are that include interfaces configured to acquire data indicating a pulse or heartbeat of an animal, and processors configured to determine whether a prescribed condition is satisfied or not based on the data indicating the pulse or the heartbeat of the animal, and calculate a respiratory rate in a period of time for which the prescribed condition is satisfied, are provided.

Abstract: A wearable instrument is provided that measures biological information over an extended period of time by enabling an electrode to be readily pressed to an axilla of an animal. The wearable instrument includes: electrodes to be placed under the left and right axillae of a dog to produce an electrocardiogram; pull-up straps to be placed in direct contact with the axilla to press the electrodes onto the axilla; and a cinch strap placed across the anterior chest of the dog to draw the left and right sections of the pull-up strap together.
