Gas sensor kit and gas supply unit
A gas sensor kit includes a gas sensor that measures a gas concentration of an exhalation gas of a subject and a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject. In the gas sensor, the gas sensor has a convex portion that is supported when connected with the gas supply unit, and the gas supply unit has at least one locking claw that supports the convex portion when connected with the gas sensor.
1. A gas sensor kit comprising:
a gas sensor that measures a gas concentration of an exhalation gas of a subject;
a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject, wherein
the gas sensor has a convex portion that is supported when connected with the gas supply unit, and a cable attachment surface to which a cable is attached, and
the gas supply unit has a pair of laterally disposed locking holes and a plurality of locking claws, wherein each locking claw partially defines an end of one of the locking holes, and wherein at least one locking claw supports the convex portion and at least one locking claw supports the cable when connected with the gas sensor.
2. The gas sensor kit according to claim 1 , wherein
the convex portion is provided on a surface opposed to the cable attachment surface.
3. The gas sensor kit according to claim 1 , wherein:
the gas supply unit includes a tube attachment surface to which a tube is attached, and
at least one of the plurality of locking claws is provided on a surface opposed to the tube attachment surface.
4. The gas sensor kit according to claim 1 , wherein:
the gas supply unit includes a tube attachment surface to which a tube is attached, and
at least one of the plurality of locking claws is provided in the same side as the tube attachment surface.
5. The gas sensor kit according to claim 1 , wherein:
the gas supply unit includes a tube attachment surface to which a tube is attached,
at least four of the plurality of locking claws form two pairs of locking claws,
a first pair of the locking claws is provided on the same side as the tube attachment surface, and
a second pair of the locking claws is provided on a surface opposed to the tube attachment surface.
6. The gas sensor kit according to claim 1 , wherein:
the convex portion has an elongated and extended shape, and
at least two of the plurality of locking claws form a paired structure with which a major axis of the extended shape is supported from both ends of the gas sensor.
7. The gas sensor kit according to claim 1 , wherein a casing of the gas supply unit has a cap shape that covers a casing of the gas sensor.
8. A gas supply unit which is connected with a gas sensor which measures a gas concentration of an exhalation gas of a subject and supplies a therapeutic gas, supplied through a tube, to the subject, the gas supply unit comprising:
a pair of laterally disposed locking holes,
a plurality of locking claws, wherein each locking claw partially defines an end of one of the locking holes, and wherein at least one locking claw supports a convex portion provided in the gas sensor, and
wherein the plurality of locking claws are provided on the same side of the gas supply unit as the side to which the tube is attached, and on a side opposite to the side to which the tube is attached.
9. A gas sensor kit comprising:
a gas sensor that measures a gas concentration of an exhalation gas of a subject; and
a gas supply unit that supplies a therapeutic gas, supplied through a tube, to the subject, wherein
each of the gas supply unit and the gas sensor has an attachment and detachment mechanism by which the gas supply unit is capable of being attached to and detached from the gas sensor so that a direction of extension of the tube is reversible.
10. The gas sensor kit according to claim 9 , wherein the attachment and detachment mechanism includes a magnet.
