Abstract
Proposed is a system for the detection and/or transmission of signals representing the vital functions, such as ECG signals and pulse rate, of patients, sports-men/women, etc. The system consists of a sensor, a sensor-signal transmitter which transmits the signals fed to it by the sensor, and a receiver unit, the transmit-ter power of a sensor attached to the patient or sportsman/woman being set at a level such that the signal will be transmitted, with-out any interference, by teleme-try to the sensor unit (22) at least within buildings, sports cen-tres, stadiums and similar facili-ties. In addition, when a multi-plicity of transmitters which are not shielded from each other are operating simultaneously within the reception range of the receiver unit (22), the transmitter frequencies lie in a non-overlapping frequency-allocation scheme.
Description
2 ~74114 A System for the Detection and /or Transmission of Signals Representing Vital Functions The present invention relates to a system for the detection and/or transmission of signals representing vital functions, such as, for example, ECG signals, heart rate, etc., as set out in the preamble to Patent Claim 1.
Prior Art Systems for the detection and/or transmission of signals representing vital functions, such as, for example, ECG signals, heart rate, and so on, from patients, athletes, or the like are known in medical technology and in the sports sciences. These systems allow users to monitor their own physical signals.
Usually, these systems are such that the person involved can move freely, i.e., a display apparatus is located in the immediate vicinity of the user or on the user's person and this serves as a receiver unit, which can be in a form of a wrist watch or a tachometer-like display on the handlebars of a bicycle.
Transmission from sensors to à receiver unit can be effected either through wires or by wireless means (telemetry).
~ The telemetric transmissions of signals has already been I described in DE 42 15 549 Al and DE 42 23 657 Al. In the systems that are described in these documents, which consist essentially of a sensor, a sensor signal transmitter for reading and retransmitting the sensor signals, and a receiver unit, the range of the sensor transmitter is quite limited. The receiver cannot be positioned at any great distance from the athlete or patients in order to permit external monitoring of the athlete or patient.
In the same way, it is scarcely possible to monitor a group of such persons using telemetry or set up an easily read display within visual range of such persons so as to permit them to 21 7477~
monitor themselves. The systems do not permit any long-term archiving and analysis of the physical signals referred to above.
Task and Advantages of the Present Invention It is the task of the present invention to eliminate the disadvantages of the prior art and permit universal use of the system so as to permit effective management of complex monitoring situations, for example, in the domain of sport, rehabilitation, and health care.
These problems have been solved by the distinguishing features as set out in Patent Claim 1.
The secondary claims describe advantageous and useful developments of the system according to the present invention.
It is the basic concept of the present invention that the system according to the present invention incorporates a transmitter that is independent of the power supply, which is set up on or in the vicinity of the patient, athlete, or the like; neither the weight nor the size of this transmitter restrict the freedom of movement of the athlete or patient. The transmitter has a power 1 output that permits interference-free transmission of the sensor signal even over long distances. If a multiplicity of such transmitters that are not shielded from each other are operated simultaneously within the reception range of a receiver unit, the transmitting frequencies of the transmitters and the receiving frequencies of the receivers lie in a non-overlapping frequency-frequency-allocation scheme. If the sensor signals display time curves that are not identical, more than one transmitter (e.g., two transmitters) can be tuned to one transmission frequency. If necessary, the number of transmitters operating on a single i 2174774 -channel can be further increased by appropriate coding of the sensor signals.
It is especially preferred if the transmitter is an additional transmitter that is located in the vicinity of the patient, athlete, or like, and the transmitter that is used to read a sensor signal that is transmitted from shorter range (< 2 meters) from a co~mercially available sensor with a sensor signal transmitter incorporate a receiver circuit or a sensor-matching circuit and an amplifier.
In a simple version of the present invention, it is advantageous that the receiver that is used to generate and emit the signals representing vital functions incorporate at least one display element with a microprocessor. The display element (e.g., a large and easily read LED display or LCD display) can be set up within visual range of the patient or athlete in order to permit said athlete or patient to monitor themselves and adapt their effort accordingly, so as to provide continuous protection against 20- physical over-exertion. In addition, this means that monitoring can be carried on by a third party.
It is particularly advantageous if the receiver of one or a multiplicity of systems has one or several interfaces to a personal computer when, in order to permit the simultaneous operation of a multiplicity of systems on one personal computer, the bus system of the interfaces to the PC incorporates a multiplexer. This makes it possible to maintain continuous records of the transmitted signals with the help of the personal computer in order to permit long-term analysis, for example, in order to optimize training.
1~ 2 1 7 47 74 Similarly, it is possible to record a multiplicity of signal patterns from completed training units over a specific time, in order to permit performance and comparative analyses.
It is also an advantage that in order to identify an individual transmitter, prior to transmission, each transmitter provides the æensor signal with a recognition signal.
, .
Finally, it is also useful if the receiver has acoustic and or optical elements to trigger an alarm to indicate individual signal limit values. In this way, it is possible to prevent the athlete, patient, or the like running the risk of over-exerting themselves physically. The limiting values can be programmed by way of a special limiting-value programming device.

~ 21 74174 Wo 95/10974 PCT/DE94/01235 The embodiment of a sensor and an additional transmitter that is shown in Figure 1 comprises a sensor with a sensor-signal transmitter 1 (for example, an infrared transmitter or an ECG
electrode), a signal line 2, a sensor matching circuit 3, an amplifier 4, a signal shaper 5, a microprocessor 6, and a high-frequency transmitter module 7. The embodiment of a sensor with a sensor-signal transmitter and an additional transmitter as shown in Figure 2 comprises a sensor with a sensor-signal transmitter 8 for the telemetric transmission of sensor signals to the receiver circuit 9 of the additional transmitter 10, an amplifier 11, a signal shaper 12, a microprocessor 13, and a - high-frequency transmitter module 14.
~ The system receiver unit that is shown in Figure 3 comprises a lS high-frequency receiver module 15, a decoder 16, a microprocessor 17 with àn interface 18, a display driver 19, and two LCD
displays 20, 21. Finally, Figure 4 shows a receiver station for the system according to the present invention that incorporates "n" receiver units 22 that each comprise the above-described modules, i.e., high-frequency receiver 15, decoder 16, microprocessor 17 and interface 18. The embodiment that is shown incorporates a bus system 25 and a multiplexer 26 to provide for communication with a personal computer 24.
System operation In order to measure pulse rate, for example, the patient or athlete wears the sensor with the sensor signal transmitter 8 in the area of the heart and this feeds the pulse signal to the additional transmitter lo by telemetry. The transmitter 10 is located at a suitable position on the patient's or athlete's clothing and transmits an HF-modulated signal to a receiver ~_ 21 74774 station 22 that is located some distance away. As an alternative, the hard-wired sensor 1 (e.g., a clip-on ear sensor) can be attached to the patient or athlete in order to detect the pulse rate. When this is done, the sensor signal is sent to the additional transmitter lo by way of the signal line 2.
The receiver unit 22 incorporates two LCD displays 20, 21, that can be installed within visual range of the athlete or patient.
The transmitter 10 is a quartz-controlled narrow band type (that operates, for example, in the 434 MH2 band in Germany) with a ~ defined frequency allocation; this provides for extremely reliable and interference-free operation, i.e., a number of ` persons (the precise number depending on the selected frequency allocation) can be monitored simultaneously in the reception area of the monitoring system. After the matching circuit 3 or a receiver circuit 9, the signal value that is picked up is appropriately amplified by an amplifier 4, 11. The signal shaper 5, 12 generates a signal that can be analyzed by the microprocessor 6, 13 that follows, which is located in the transmitter. The microprocessor 6, 13 computes an average value from a number of incoming sensor signals, carries out validity tests, and generates the data record that is then fed to the high-frequency transmitter module 7, 14. The data record contains the transmitter identification, the signal value identification (e.g., for heart rate or ECG signal), the signal value information, and the system time. The transmitter power can be adjusted to match it to different areas of use. The high-frequency receiver module 15 of the receiver unit 22 receives the coded data that is transmitted from the high-frequency transmitter module 7, 14 and passes it to the decoder 16. The decoded signals are processed by the microprocessor 17. The microprocessor can carry out a minimum or maximum analysis, and in the event that a programmed limiting value is either exceeded or not reached, can trigger an alarm signal. The sensor-signal values are displayed on the two LCD
displays 20, 21 by the display driver 19. In parallel to this, data can be output through an interface 18 (e.g., RS232 interface) to a personal computer 24.
~.
- In the case of a plurality of systems that are operated simultaneously with the receiving unit 23, the data can be output to the personal computer 24 alone. The data are read into the - personal computer 24 through the interfaces 18, the bus system 25, and the multiplexer 26. Association with each particular ~ transmitter is effected with the help of the transmitter identification. In a simple manner, the personal computer can display the incoming data, store it, and either display it or output it in real time in the form of tables, graphs, and calculations by way of a monitor or a printer.
