Determination device, determination method, and sensor device
In order to provide a novel determination device capable of determining the type of excretion by a subject and a related technology thereof, a determination device includes at least one processor, and the at least one processor carries out a determination process of determining the type of excretion by a subject by referring to a first gas concentration detected by a first gas sensor and a second gas concentration detected by a second gas sensor which differs from the first gas sensor in gas species to be mainly detected.
1 . A determination device comprising at least one processor,
the at least one processor being configured to carry out a determination process of determining a type of excretion by a subject by referring to a first gas concentration detected by a first gas sensor and a second gas concentration detected by a second gas sensor,
the first gas sensor being configured to detect a first gas derived from a stool,
the second gas sensor being configured to detect a second gas that is derived from flatus and that differs from the first gas,
in the determination process, (i) in a case where the first gas concentration detected by the first gas sensor is greater than or equal to a first threshold, the at least one processor determining that the type of excretion by the subject is a stool and thereafter ending the determination process, and
in the determination process, (ii) in a case where the first gas concentration detected by the first gas sensor is less than the first threshold, and the second gas concentration detected by the second gas sensor is greater than or equal to a second threshold, the at least one processor determining that the type of excretion by the subject is flatus.
2 . The determination device according to claim 1 , wherein the at least one processor is configured to further carry out a notification process of notifying a notification terminal used by a service provider of the type of excretion determined.
3 . A determination method comprising:
an acquisition process of at least one processor acquiring a first gas concentration detected by a first gas sensor and a second gas concentration detected by a second gas sensor; and
a determination process of the at least one processor determining a type of excretion by a subject by referring to the first gas concentration and the second gas concentration,
the first gas sensor being configured to detect a first gas derived from a stool,
the second gas sensor being configured to detect a second gas that is derived from flatus and that differs from the first gas, and
in the determination process, the at least one processor determining that the type of excretion by the subject in the following manner:
(i) in a case where the first gas concentration detected by the first gas sensor is greater than or equal to a first threshold, the at least one processor determines that the type of excretion is a stool and thereafter ends the determination process; and
(ii) in a case where the first gas concentration detected by the first gas sensor is less than the first threshold, and the second gas concentration detected by the second gas sensor is greater than or equal to a second threshold, the at least one processor determines that the type of excretion is flatus.
4 . A sensor device comprising:
a first gas sensor configured to detect a first gas derived from a stool; and
a second gas sensor configured to detect a second gas that is derived from flatus and that differs from the first gas,
the sensor device being configured to transmit, to a determination device configured to determine a type of excretion by a subject, a first gas concentration detected by the first gas sensor and a second gas concentration detected by the second gas sensor,
in the determination device, at least one processor carrying out a determination process of determining the type of excretion by the subject by referring to the first gas concentration detected by the first gas sensor and the second gas concentration detected by the second gas sensor; and
in the determination process,
(i) in a case where the first gas concentration detected by the first gas sensor is greater than or equal to a first threshold, the at least one processor determining that the type of excretion by the subject is a stool and thereafter ending the determination process;
(ii) in a case where the first gas concentration detected by the first gas sensor is less than the first threshold, and the second gas concentration detected by the second gas sensor is greater than or equal to a second threshold, the at least one processor determining that the type of excretion by the subject is flatus.
