Abstract
In an adaptor for a flow sensor, a tubular body is adapted to allow respiratory gas to pass through. At least one fluid-resistant member is disposed in the tubular body. At least two pairs of first passages are formed in the fluid-resistant member and adapted to lead out pressures at two positions in the tubular body which are to be detected by the flow sensor.

An adaptor for a flow sensor, comprising:
- a tubular body, adapted to allow respiratory gas to pass through;
- at least one fluid-resistant member, disposed in the tubular body;
- and
- at least two pairs of first passages, formed in the fluid-resistant member and adapted to lead out pressures at two positions in the tubular body which are to be detected by the flow sensor.
1 more element
A connector, comprising:
- a body, adapted to be attached to a tubular body of an adaptor for a flow sensor;
- a plurality of first joint pipes, each of which is adapted to be coupled with an external tube, and communicated, when the connector is attached to the tubular body, with at least one of holes each of which is formed on the tubular body and communicated with at least one of first passages formed in a fluid-resistant member disposed in the tubular body for leading out pressures at two positions in the tubular body, wherein:
- the first joint pipes extend in an axial direction of the tubular body when the connector is attached to the tubular body;
- and
- the body and the first joint pipes are monolithic.
