Abstract
Pressure sensing devices for use with an inflatable bladder and monitoring apparatus for an at rest subject are disclosed herein. The device can comprise a housing comprising a recess and configured to be welded in a seam of the inflatable bladder. A pressure sensor can be located within the recess with a sensing side configured to be exposed to the cavity of the inflatable bladder and a reference side configured to be exposed to ambient air. A printed circuit board can be located within the recess and coupled to the pressure sensor. The pressure sensor is operable to detect a pressure change within the cavity due to a force exerted by a subject on the inflatable bladder.
Claims18
An apparatus for monitoring a subject at rest comprising:
- an inflatable bladder comprising a cavity containing a fluid and a hermetically sealed seam;
- a housing hermetically sealed within the seam, the housing having a distal end with a distal aperture there through opened to the cavity, a proximal end with a proximal aperture there through opened to atmosphere, and an opening accessing a recess having a track provided in each side wall of the recess;
- a pressure sensor having a sensing side exposed to the cavity of the inflatable bladder and a reference side exposed to ambient air within the recess of the housing;
- and
- a printed circuit board coupled to the pressure sensor, wherein the pressure sensor is operable to detect a pressure change within the cavity due to a force exerted by a subject on the inflatable bladder,
- wherein the pressure sensor and the printed circuit board are mounted on a planar base configured to slide within each track through the opening into the recess so that the pressure sensor and printed circuit board are fully within the recess.
A pressure sensing device for use with an inflatable bladder, the device comprising:
- a housing comprising a center portion having an opening accessing a recess having a track provided in each side wall of the recess, the housing configured to be welded in a seam of the inflatable bladder;
- a pressure sensor having a sensing side configured to be exposed to the cavity of the inflatable bladder through a distal end of the housing and a reference side configured to be exposed to ambient air within the recess of the housing;
- and
- a printed circuit board located within the recess and coupled to the pressure sensor, wherein the pressure sensor is operable to detect a pressure change within the cavity due to a force exerted by a subject on the inflatable bladder,
- wherein the pressure sensor and the printed circuit board are mounted on a planar base configured to slide within each track through the opening into the recess so that the pressure sensor and printed circuit board are fully within the recess.
