TILT SENSOR FOR USE WITH PROXIMAL FLOW SENSING DEVICE
First Claim
Patent Images
1. A sensor adapted to detect and provide information related to tilted and non-tilted orientations, the sensor comprising:
- a first flow-through port adapted to receive a first fluid flow; and
a flow stopping member, wherein the flow stopping member is moveable between a first position and a second position, wherein, while the flow stopping member is in the first position, flow of the first fluid through the first flow-through port is measurably inhibited by the flow stopping member and the orientation of the sensor corresponds to a substantially non-tilted orientation.

Abstract
A tilt sensor is provided that is generally adapted to detect tilted and non-tilted stated of an object associated therewith, which in some cases is a ventilation circuit component. The tilt sensor may correspond to a pneumatically operated tilt sensor that can be used in conjunction with a ventilator to help prevent compromised measurements from certain elements which can be used in a ventilator patient circuit.

9. A method of determining an orientation of an object, comprising:
-
receiving a fluid flow in a primary flow path; detecting at least one of an increase in the fluid flow through the primary flow path and a decrease in pressure in the primary flow path; and in response to the detecting step, determining that the primary flow path comprises a tilted orientation. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A system, comprising:
-
a primary fluid flow path; a tilt sensor comprising a fluid flow path and a flow stopping member adapted to inhibit fluid from flowing through the tilt sensor fluid flow path in a first position and further adapted to allow fluid flow through the tilt sensor fluid flow path in a second position; and a pressure sensor operable to detect that the flow stopping member is in the second position by detecting a decrease in fluidic pressure in the primary fluid flow path. - View Dependent Claims (19, 20, 21)
