Abstract
An interface pressure monitoring system includes an underlayment interposed between a patient support surface and a patient supported thereon and a processor. The underlayment includes pressure sensors such as, for example, an array of piezoelectric pressure sensors. The processor acquires pressure data from the underlayment, analyzes the data and stores the analyzed data for further processing, alerting and/or reporting.
Claims21
A system for monitoring localized interface pressures produced between a surface and a patient supported thereon, said monitoring system comprising:
- an underlayment adapted to be interposed between a patient support surface and a patient resting adjacent said patient support surface, said underlayment comprising a plurality of pressure sensors;
- and
- a processor in electrical communication with said pressure sensors of said underlayment, said processor being adapted to:
- acquire and map pressure data as measured by said pressure sensors;
- store said mapped pressure data;
- analyze said stored pressure data for the determination of the body position of the patient from the group consisting of:
- the supine position;
- the prone position;
- and
- a lateral position;
- determine, based upon whether the determined body position of the patient has remained unchanged, from one said body position to another said body position, over a length of time exceeding an established threshold value, whether repositioning of the patient should take place;
- generate a graphical image of said mapped pressure data, wherein said graphical image comprises a written language identification of the regions of the body of the patient that are placed at heightened risk for tissue breakdown as a result of the determined body position of the patient remaining unchanged over a length of time exceeding said established threshold value;
- and
- display, through a user interface, said graphical image.
