Definitions

  • the present invention relates to a supervision system for the automatic registration of data concerning people in need of care. A method for such supervision is also disclosed.
  • Smart houses are houses for people with special needs, for example elderly or disabled. In such houses, functions and services related to the diseases or handicaps from which the inhabitants suffer should be provided. Such functions may be, for example, if the person has a heart problem, monitoring the heart rhythm, or if the person falls out of bed.
  • a “bed guard” exists for use in so called smart houses.
  • the “bed guard” is a small sheet, (100cm x 50cm with a thickness of 28mm) to be placed on top of the ordinary mattress. It comprises a pressure sensor registering if someone is lying on the bed. If the person leaves the bed for longer than a predetermined period of time, an alarm may be triggered, so that the person may be helped back to bed.
  • This "bed guard” only registers presence, and transmits no other information than an alarm signal. Being a separate sheet, it is also easily moved or deformed, so that it does not function properly.
  • Patent Specifications US 5 515 865 and US 4 895 160 describe mattresses for the supervision of sudden infant death.
  • the mattresses comprise pressure sensors for registering breathing and initiate an alarm if the breathing stops for a longer than a predetermined period of time.
  • the system disclosed in US 5 515 865 also triggers actions to stimulate the infant if the breathing stops.
  • the system disclosed in US 4 895 160 also comprises other types of sensors, for example, for temperature and humidity in the room. The systems do not differentiate between different types of problems and no information other than an alarm is transmitted.
  • Biofeedback is a method of helping people control their stress levels, that is reducing the negative effects of stress in everyday life.
  • the user is sitting or lying down while the reactions of the body, such as heart rate or breathing rate, are registered, the signals are amplified and displayed to the user, for example, on a screen or in the form of sound pulses. In this way, the user is informed about his own reactions and how they vary. Experiments have shown that it is possible in this way to control your physical stress reactions and relax better.
  • a communications system for transmitting information about the state of a person, comprising a mattress comprising at least one type of sensor for registering at least one body function of a person lying on the mattress, and a communications module for transmitting data through a standard telecommunications interface.
  • the communications module is adapted for wireless communication.
  • the communications system also comprises a signal processing means and means for converting the output signals from the sensors to input signals of the appropriate format for the processing means.
  • the mattress may comprise, for example, the following sensors
  • the sensors are essentially the same type of acoustic pressure sensors, each transmitting a signal comprising a spectrum of frequencies.
  • the processing means then preferably comprises functions for separating the signal frequency components.
  • a preferred embodiment of the mattress comprises air compartments surrounded by a flexible material, such as foam rubber.
  • the sensors may be located in the air compartments, each sensor being enclosed in an essentially hemispherical or hemicylindrical capsule.
  • the walls of the capsule are selected so that pressure changes from the desired direction are registered by the sensor whereas pressure changes in all other directions are attenuated by the capsule walls.
  • a method for using the apparatus is also disclosed in which the sensors register whether or not someone is present on the mattress. Other data is registered only when a person is found to be lying on the bed.
  • Data about a client's state may be transmitted, for example, to one or more of the following:
  • Data may be transmitted and/or stored for several different purposes:
  • the invention enables sick, elderly or disabled people to continue living in their homes even as their need of care increases.

  • a number of pressure sensors 13 located in the hip region of the mattress detect the pressure on the mattress, and thereby whether or not a person is lying on the bed. If the person leaves the bed for a period of time exceeding a threshold value, an alarm may be transmitted.
  • the system is provided with software that registers, and adapts to, a pattern of behaviour for a certain person, so called habit cycle monitoring.
  • sensors 15 for registering heart activity there are sensors 15 for registering heart activity, and sensors 17 for registering respiration.
  • the sensors 15 for registering heart activity may be sensitive pressure or acoustic sensors registering sound or pressure or vibration sensors.
  • the sensors 17 for registering respiration are preferably pressure or acoustic sensors or detectors.
  • This second set of pressure sensors 19 may be used together with the first set of pressure sensors 13 to register epileptic seizures, which are associated with characteristic movement patterns.
  • the acoustic sensors may register other symptoms, such as coughing.
  • the sensors 13, 15, 17, 19 are preferably arranged in a mattress with air filled closed cavities, which will function as a resonance chamber, amplifying the sounds. In the chest region there may also be a second set of pressure detectors.
  • the pressure sensors 13, 19 and the heart rate and respiration sensors 15, 17 may also be used to determine whether or not the person lying on the mattress is asleep, in which case he will move very little and the heart rate and the breathing will be slower. If the person wakes up at night, this will normally be detected by the system as a period of tossing and turning.
  • the vibration elements may start vibrating to induce sleep.
  • the frequencies used should be adapted to the frequencies of the human brain in the state of relaxation and sleep, respectively. When a person lies down on the mattress, the relaxation may start with vibrations corresponding to the frequency of the brain during sleep (0.5Hz-3Hz).
  • calming pulsations may be initiated, which may have a frequency between 3Hz and 12Hz, corresponding to the frequency of the brain when a person is totally relaxed. This will cause the person to become more relaxed.
  • the frequency may then be reduced, step- wise if desired, to the frequency corresponding to sleep (0.5Hz - 3Hz).
  • the vibrations may stop. This is registered by one or more of the sensors 13, 15, 17, 19.
  • the pressure sensors 13, 19, the heart rate and respiration sensors 15, 17 may also be used together with a pair of loudspeakers and/or the vibration elements, in a biofeedback system.
  • the pressure sensors 13, 19 are then primarily used to register the presence of the person. Other sensors are only activated if someone is lying on the mattress.
  • the same set of sensors are used for registering presence, movements, heart rate and respiration.
  • the sensors are then sensitive acoustic sensors, that register air pressure and changes in air pressure.
  • the signal registered by the sensors will then be a combination of a number of different signals with different frequencies.
  • the different components are extracted using analysis methods known in the art.
  • each of the acoustic sensors is arranged in a capsule, which is preferably hemispherical or hemicylindrical.
  • the remaining walls of the capsule are preferably insulated so that no pressure or pressure changes will be transferred through these walls. In this way, only pressure and pressure changes taking place above the capsule will be registered.
  • the sensor should be sensitive to low frequency pressure changes, in the range from 0Hz to lOHz.
  • Figure 2 shows a cross-section of a mattress 25 according to a preferred embodiment of the invention, seen from the side, with a person lying on it.
  • the difference compared to Figure 1 is that the control device 29 is built into the head end of the mattress.
  • the control device may of course be placed in other parts of the mattress, but the head end is feasible, since the control device can easily be placed there without being noticeable to the person lying on the bed.
  • the number of cables needed is also reduced.
  • the mattress 25 has an upper 26 and a lower 27 layer.
  • the upper layer is made of, for example, foam rubber with air channels, approximately 7-8 mm wide, running across the mattress with approximately 5cm between the channels. As shown in the figure, the air channels widen at the bottom. Thus 15-20% or the surface on which the person is lying is air. the rest is foam rubber or another suitable material which adapts better to the shape of the body because of the air channels.
  • One or more weight sensors 31 are arranged in the mattress in the region on which the person's hips will be located, for registering presence and movements. Sensors for heart and lung activity, 33 and 35 respectively, are arranged in the mattress below the chest of the person.

Abstract

L'invention concerne un matelas comprenant un certain nombre de capteurs permettant d'enregistrer des fonctions du corps comme la fréquence cardiaque ou la respiration d'une personne allongée sur ce matelas. Les données sont transmises à un centre de soins de santé ou similaire, chargé de surveiller les paramètres de santé de la personne. Un certain traitement des données peut être réalisé localement dans un ordinateur, par exemple, pour déclencher des alarmes dans différents types de situations d'urgence. Le matelas peut également comprendre des éléments vibrants permettant d'induire des vibrations calmantes et de prévenir les escarres localisés aux points d'appui.
