Definitions

  • Monitoring device for diminishing the risk of acuiring pressure ulcers.
  • Pressure ulcer development is a major problem in many groups of patients, among others in patients with spinal cord injuries (SCI) who are for long periods sitting down in their wheel chairs.
  • SCI spinal cord injuries
  • the prevalence of pressure ulcers among these groups has been reported to be as high as 20 - 30 %.
  • Other exposed groups are old patients or persons that have a decreased sense of consciousness, due to injury or disease, for instance in intensive care or during surgery.
  • the pressure ulcer is in it self a medical hazard as it can become the forerunner of serious (potentially life threatening) infections.
  • the ulcer also imposes social limitations and inconvenience for the patient.
  • the alternative is plastic surgery.
  • the healing period takes several months, during which the patient must relieve his or her area of sitting continuously.
  • the rehabilitation after an operation usually takes about four to six weeks and both methods inflicts great suffering for the patient and high costs for the society.
  • Figure 1 shows a battery operated electronic device according a preferred embodiment of the invention
  • the Communication unit board 20 comprises a Microcontroller 21, an Analogue to digital converter 22, a Bluetooth module 23, Voltage converters 26, an USB connector 24, a Battery charger 25 and a Connector to the Alarm unit 27. Power is supplied to Communication unit circuit board 20 via the Battery 3 which is connected to the battery charger 25 and the Voltage converters 26.
  • the battery 3 supplies power to the Communication unit board 20 and the Alarm unit 30 and can be charged via the charger 25 by inputting power through the USB connector 24.
  • the voltage converters 26 converts the voltage from the Battery 3 to suitable violate levels.
  • the charger 25 could be left out if non-rechargeable batteries where used or if the battery would be charged externally.
  • the Pressure sensors 5 can be connected to the Alarm unit 30 via the Data cable 4 and the Connector to sensors 36.
  • a number of Amplifiers 31 amplifies the pressure signals from the Pressure sensors 5. For each Pressure sensor 5 there is a corresponding Amplifier 31, thus the number of Pressure sensors 5 should be lower or equal to the number of Amplifiers 31, normally their numbers being equal. In the current design there are 8 Amplifiers 31 and 8 Pressure sensors 5, however the invention is not limited to these numbers.
  • Pressure data and/or an alarm history can be stored on a memory card in Digital memory card reader 34, which then can be removed and inserted in an external unit for analyses of the stored data.
  • An external unit attached to any of the interfaces can send preferences to the Microcontroller 21 to update its software or to change parameters.
  • the Pressure sensors 5 can be integrated in a protective cover for measuring under larger surfaces at a number of measuring points such as in the case of surveying the risk for pressure ulcers for a person confined to a wheel chair.
  • TimeK is a time constant, which is determined by the updating frequency of the pressure signals from the Pressure sensors 5.
  • PressureEnergy is a variable that is used to hold a value that we call the pressure energy. It is defined as the pressure integrated over the time constant TimeK. Where the pressure is determined based on the amplified pressure signals from the Pressure sensors 5.
  • Step 43 PressureEnergy is weighted by ReBehaviour and the output is called RiskLevel.
  • the alarm can take into account the level of pressure and for how long it consists, or likewise for how long time a period of pressure relief lasts. This makes it possible for the alarm to go off at a correct point of time instead of giving off false alarms or missing to give off an alarm when it should. For instance if the pressure is very high the alarm will go off faster than if there is a lower pressure. If the duration of the pressure relief is short, the alarm will activate again, after a shorter time than if a long period of pressure relief had been done.
