Definitions

  • the invention relates to a device for making an emergency call with the aid of an emergency call device which, when a trigger signal arrives, issues the emergency call, a mobile emergency transmitter being provided which transmits a trigger signal to the emergency call device on command of the user.
  • Automatic emergency call systems play an important role in the care of the elderly and the sick. If necessary, the user can make an automatic emergency call at any time by operating a device provided for this purpose, which is forwarded to the appropriate places.
  • Known emergency call systems work with a small emergency transmitter (also called radio finger) that the needy always carries with them or that is mounted on a wheelchair and that sends a trigger signal at the push of a button.
  • the trigger signal is intercepted by a permanently installed emergency call device, which makes an emergency call.
  • a permanently installed emergency call device which makes an emergency call.
  • the emergency call device can, for example, be installed in a central building or in the user's apartment and can be connected to a telephone line or directly to a care station.
  • the object of the present invention is to provide a device which automatically makes an emergency call in dangerous situations.
  • a device which is characterized by at least one monitoring device which is connected to at least one sensor for monitoring the condition of the user and which has means for deriving a trigger signal when impermissible conditions occur to the emergency call device.
  • an emergency call can also be made actively by the user by pressing the send button on the emergency transmitter. If this is not possible for him, the emergency call is automatically made if an impermissible combination of measured values occurs.
  • the system can be expanded as required, taking additional sensors into account.
  • the user can be made aware of an impending false alarm by at least one signal generator for warning the user when a trigger signal occurs.
  • the user must be able to prevent the emergency call. This can be achieved by means of manual suppression of a previously triggered emergency call by the user, for example by a button on the emergency call device, the actuation of which prevents an emergency call. After a preset period of time has elapsed, the emergency call is made if the user does not prevent this in time.
  • a monitoring device which can be worn on the body and has at least one sensor for monitoring body functions, which emits a trigger signal when an impermissible state occurs.
  • Belts that can be worn on the body in the thorax area and that contain sensors for measuring breathing, heart rate, body temperature or other physical or biological parameters can be used, for example, to monitor body functions. The person in question
  • Monitoring device can be built into the belt or worn as a separate device to which the sensors transmit the measurement signals by wire or wirelessly. Appropriate transmission equipment also makes it possible to transmit the measurement data directly to a stationary monitoring device.
  • a monitoring device which is designed to receive and process one or more of the measurement signals emitted by the sensors, is stationary and is connected to the emergency call device for transmitting trigger signals. The measurement signals emitted by the sensors are transmitted to the monitoring device.
  • At least one of the sensors is equipped for the wireless transmission of the measurement signals to the stationary monitoring device.
  • the monitoring device of this embodiment of the invention as with the portable monitoring devices, there is an expedient plausibility check and evaluation of the measurement signals of the associated sensors.
  • a trigger signal is emitted.
  • the trigger signal can be a pure switching signal or also contain evaluation data regarding the urgency or the type of the trigger signal.
  • monitoring devices have means for linking and / or evaluating received measurement signals and for deriving trigger signals to the emergency call device.
  • the trigger signals are expediently transmitted between the monitoring devices and the emergency call device in digitized form in order to largely avoid reception errors.
  • the emergency call device has means for logically linking the trigger signals.
  • the emergency call device recognizes any existing evaluation data of the monitoring devices and links the trigger signals according to their urgency or combinatorial requirements. For example, it can be provided that certain signals always lead to an emergency call and others whose evaluation data indicate this should only lead to an emergency call if they occur together with further trigger signals. For example, the trigger signal transmitted by pressing the emergency button from the emergency transmitter should have absolute priority and lead directly to an emergency call, regardless of other signals.
  • the emergency call device makes a decision as to whether an emergency call is made or not.
  • each monitoring device can be equipped with its own transmitter, or it can become the portable emergency transmitter by the respective
  • Two further advantageous refinements of the invention can be achieved by an inclinometer that can be worn on the body and is connected to a monitoring device for detecting a fall, or by an inclinometer that can be mounted on a wheelchair and is connected to a monitoring device to detect a tipping over of the wheelchair. Furthermore, it can be advantageous to attach a seat contact that can be mounted on a wheelchair and is connected to a monitoring device. In the event that the user passes out and falls off the wheelchair or if the wheelchair tips over, the connected monitoring device detects this and there is a trigger signal which causes the emergency call device to make an emergency call. If the wheelchair is empty anyway or the user leaves the wheelchair, there is no trigger signal.
  • the condition of people is asleep is monitored by a contact mat connected to a monitoring device for application in a bed, which has sensors for measuring at least the mechanical load on the mat.
  • a monitoring device for application in a bed
  • Such mats usually contain a number of pressure, temperature and moisture sensitive sensors that sense fine mechanical vibrations, load differences, temperatures and humidity. This allows the breathing movement of a person lying on it to be monitored very precisely. Heart activity or tremors can also be determined. Furthermore, the body temperature or moisture can be detected and the associated
  • Monitoring device can be transmitted for evaluation. With such a mat, possibly in conjunction with a time measurement, it is possible to reliably detect dangerous respiratory arrests or epileptic seizures, which then lead to an emergency call.
  • the measurement of the oxygen content of the blood is achieved by means of a sensor which can be worn on the ear and is equipped with a transmitter for transmitting measurement signals and is designed to measure the oxygen content of the blood.
  • a sensor is worn similar to a hearing aid and has a transmitter for transmitting its measurement signals.
  • Monitoring devices are adjustable. This can prevent the monitoring devices from striking in those cases when there is a short-term change in the measured values approved by the user. This includes, for example, increasing the maximum permitted heart rate before exercising or decreasing the minimum permitted heart rate before going to bed.
  • An emergency call device suitable for the construction of an emergency call system according to the invention is characterized in that, in addition to an input for the trigger signal of the emergency transmitter, at least one further input is provided for at least one further trigger signal.
  • the trigger signals can be transmitted both galvanically and wirelessly from a connected monitoring device to the emergency call device.
  • the emergency call device In order to give the user the opportunity to prevent the emergency call by actuating the means provided for this purpose, it is provided in a first embodiment of the emergency call device according to the invention that means are provided for delaying the emergency call triggered by the at least one further trigger signal by a predefinable period of time. Depending on the local conditions, it may make sense not to specify the time period constantly, but to keep it variable. For this purpose, in a further development of the emergency call device according to the invention it is provided that the time period is adjustable.
  • An emergency transmitter suitable as a manual trigger for a device is characterized in that at least one input for the measurement signals of at least one sensor and means for transmitting a trigger signal when an impermissible state occurs are provided.
  • this emergency transmitter can also serve as a transmission station for other sensors or monitoring devices.
  • the emergency transmitter can also be designed with evaluation electronics for monitoring measurement signals.
