Pressure relief reminder and associated method for the prevention of pressure sores
First Claim
1. An apparatus for preventing the formation of pressure sores on the skin of an individual, comprising:
- an inclination sensor for detecting a change in inclination from an initial nontilted position to a subsequent tilted position;
a microprocessor in communication with said inclination sensor, said microprocessor configured for generating an indication signal at the end of a timing cycle and said microprocessor configured for resetting the timing cycle based upon input from said inclination sensor; and
an indicator in communication with said microprocessor, said indicator configured for alerting the individual of the need to relieve pressure on certain areas of the skin of the individual upon receiving said indication signal from said microprocessor, wherein said microprocessor is configured for generating said indication signal to cause said indicator to alert the individual when said inclination sensor detects an inclination in the initial nontilted position, wherein in the initial nontilted position at the end of the timing cycle said indication signal is generated and the alert is issued by said indicator, wherein the alert is issued in the initial nontilted position;
wherein said microprocessor is configured such that subsequent to said indicator issuing the alert said inclination sensor detects a change from the initial nontilted position to the subsequent tilted position that causes said microprocessor to prevent resetting of the timing cycle to prevent generation of said indication signal to prevent issuing of the alert when in the tilted position; and
wherein said microprocessor is configured for resetting the timing cycle subsequent to detecting the tilted position by said inclination sensor to generate a subsequent indication signal to cause said indicator to issue a subsequent alert when said inclination sensor indicates a change from the tilted position back to the initial nontilted position without the need to manually reset the timing cycle, wherein the subsequent alert is issued in the initial nontilted position.

Abstract
An apparatus and method for preventing the formation of pressure sores on the skin of an individual is provided. The apparatus includes an inclination sensor for detecting a change in inclination of an object holding the individual. A microprocessor is in communication with the inclination sensor and generates an indication signal at the end of a timing cycle. The microprocessor resets the timing cycle based upon input from the inclination sensor. An indicator is in communication with the microprocessor and alerts the individual of the need to relieve pressure on certain areas of the skin of the individual upon receiving the indication signal.
