Abstract

Some patients and infants cannot communicate and may not be monitored 24x7. If they begin to suffer pain, it may not be detected for a significant period of time. Patients with diminished cognitive function or infants may not be able to express that they are feeling some level of discomfort. A means to track the signs of pain and alert appropriate caregivers could potentially alleviate needless and significant discomfort. This invention describes a device for patients unable to express themselves that can detect the possible signs of pain and discomfort and alert caregivers who would be able to provide some level of relief for the patient.

System to detect pain in patients who can 't express themselves.

Some Patients and infants cannot communicate and may not be monitored 24x7. If they begin to suffer pain, it may not be detected for a significant period of time. Patients with diminished cognitive function or infants may not be able to express that they are feeling some level of discomfort.. A means to track the signs of pain and alert appropriate caregivers could potentially alleviate needless and significant discomfort.

A number of behavioral scales currently exist using a manual observation of the patient for a short time to determine pain. An on-going holistic of all factors with a baseline and moving comparison was not found.

Assessment and detection of pain in noncommunicative severely brain-injured patients - http://www.coma.ulg.ac.be/papers/vs/schnakers_ExpertRevNeurother2010.pdf

Articulates the problem of detecting pain in severely brain damaged patients and discusses a number of behavioral scales with observation as possible solutions.

Pain Assessment IN Advanced Dementia (PAINAD) - http://www.geriatricpain.org/Content/Assessment/Impaired/Pages/PAINADToolInstru ctions.aspx

This pain behavior tool is used to assess pain in older adults who have dementia or other cognitive impairment and are unable to reliably communicate their pain. It can be used by a nurse or by a CNA to screen for pain-related behaviors. A nurse observes the patient for 3-5 mins and selects scores on the checklist to determine an overall score that suggest pain.

Premature Infant Pain Profile (PIPP)

The Premature Infant Pain Profile (PIPP) is a behavioral measure of pain for premature infants. A nurse manually scores the patient before a painful procedure and then again after. Includes behavioral state, heart rate, oxygen saturation, brow bulge, eye squeeze, and nasolabila furrow.

Device for detecting pain sensation - https://www.google.com/patents/EP1878382B1

This invention is based on the concept that information concerning pain is contained in the waves that propagate through an artery. The device measures the waves passing through a patients arteries and calculates pain levels from that information.
