Abstract

A patient care system for monitoring respiratory distress problems and providing therapeutic treatment comprising, a sensor for generating patient derived respiratory activity signals, detecting an apnea episode from the signals, and providing in response to a detected apnea episode, stimulation of the patient by a momentary inflation of a pneumatic means adapted for placement under the patient to raise the patient and induce loss of equilibrium for startling the patient into a natural respiration pattern.

Claims

1. An inflatable pneumatic unit of the air mattress configuration for use in a respiratory stimulator system comprising:

a unitary inflatable casing constructed of an elastomeric material and having a plurality of open-ended intercommunicating elongated segments, said segments opening via at least one end thereof into the interior of the casing proximate at least one side of the casing; and

a singular relatively rigid apertured pneumatic tube extending into and along the interior of said at least one side of said casing and proximate the one ends of said segments, the apertures of said tube being predeterminably located to be in close communication with said segments, said tube being arranged within said casing for preventing said casing from becoming folded over and for providing uniform rapid momentary inflation and deflation thereof.

2. A unit according to claim 1 wherein a longitudinal portion of the exterior of said relatively rigid pneumatic tube constitutes a part of the exterior of said casing and said apertures are provided in that longitudinal portion of said tube in communication with the interior of said casing.

3. A unit according to claim 1 wherein the shape of said casing is substantially rectangular, and wherein said segments are arranged to extend substantially parallel to each other and substantially perpendicular to the portion of said pneumatic tube extending into the interior of said casing.

4. A unit according to claim 3 wherein said relatively rigid pneumatic tube enters the interior of said casing of one corner thereof and runs at least the length of said one side of said casing.

5. A pneumatic stimulating device comprising an inflatable elastomeric casing having in the interior a plurality of open-ended segmented areas coupled together by way of at least one internal common area, and a substantially rigid pneumatic tube extending into the interior of said casing, said pneumatic tube extending along said common area and being predeterminably apertured to provide a corresponding predetermined number of tube ports to be situate proximate the portion of each said segmented area coupling into said common area for enabling a uniform rapid inflation and deflation of said casing.
