A sensor insertion assembly includes: a sensor insertion device comprising a needle member configured to be inserted in a living body together with a biological information sensor and to be pulled out of the living body after leaving a distal end side of the sensor in the living body; and a base plate detachably attached to a first end side of the sensor insertion device, the base plate comprising a clamp portion configured to move so as to clamp a proximal end side of the sensor extending to an outside of the living body after pulling out the needle member and along with an operation of detaching the sensor insertion device from the base plate.

Sensor insertion device set and base plate

A sensor insertion device includes: a housing; a needle member comprising a needle portion configured to be inserted in the living body with a sensor and to be movable in the housing in an insertion direction and a pulling-out direction; a first urging member configured to urge the needle member in the insertion direction to move the needle member to a first position; a second urging member configured to urge the needle member in the pulling-out direction to move the needle member that has reached the first position to a second position; and a switching mechanism configured to perform selective switching from movement of the needle member by an urging force of the first urging member to movement of the needle member by an urging force of the second urging member when the needle member reaches the first position.

A sensor insertion device includes a first elastic member; a second elastic member; an elastic energy variable mechanism configured to elastically deform the first elastic member and the second elastic member to achieve an energy accumulated state; a first holding mechanism configured to hold a position of the first elastic member in the energy accumulated state; and a second holding mechanism configured to hold a position of the second elastic member in the energy accumulated state for a period of time during which, after the release of the first elastic member from the first holding mechanism in the energy accumulated state, the needle member is moved to the insertion position by the first elastic energy.

Sensor insertion device and replacement part

A light guide unit of a fluorescence sensor is disclosed, which includes at least an optical-waveguide film in which one or more optical waveguides are formed. Each of these films includes a plurality of optical channels that output excitation light (E) or input fluorescence (F). All the optical channels are covered with a fluorescence unit.

Fluorescence sensor

A digestive tract device that can reduce an indwelling-induced burden on the living body includes: a tubular portion that includes a through hole; a holding portion that is provided on a proximal end side of the tubular portion, and holds the tubular portion in the living body; and support portions and which are provided in the holding portion, and are in contact with a plurality of sites of the digestive organ of the living body, and support the holding portion in such a way that the holding portion can move in at least one direction of a circumferential direction and a longitudinal direction of the tubular portion.

Digestive tract device

A component measuring apparatus is provided with a case having a cylindrical case main body and a cover arranged to cover the base end opening section of the case main body; a chip mounting section for mounting a chip; a light measuring section for detecting a prescribed component; a printed board whereupon a control section having a function of controlling the operation of the light measuring section is arranged; a liquid crystal display device; a battery arranging section for arranging a battery provided on the cover; an O-ring arranged between the case main body and the light measuring section on the leading end section of the case main body; and an O-ring arranged between the case main body and the cover on the base end opening section of the case main body. Sealing of inside the case is ensured by the O-ring.
