Medical Measuring Device

Abstract

The invention relates to a medical measuring device (10) comprising at least one measuring apparatus (12, 14), which has at least one sensor (16, 18) for generating a measuring signal of a patient (20, 22). A measuring data detection device (24) is also provided, which is designed to exchange measuring signals with the at least one measuring apparatus (12, 14) via an, in particular, wireless communication route (24, 26). The at least one measuring apparatus (12, 14) is designed to signal the quality of the measuring signals.

Description

Further advantages of the application possibilities of the present invention emerge from the following description of an embodiment of the invention with the single drawing.

The single FIGURE of the drawing shows a medical measuring device 10 in the form of a distributed medical measuring system with measuring apparatuses 12 and 14 and a central measuring data detection device 24 which is used for storing and displaying medical measuring data and for central control of the measuring apparatus 12 and 14.

The measuring data detection device 24 comprises an LCD display screen 38 for displaying medical measuring data. The medical measuring data comprise, for example, a curve pattern 42 and numerical values 40 for measuring values. The measuring data detection device 24 has various operating elements 46 for adjusting measuring parameters, the display on the screen 38 and functions of this type of the measuring data detection device 24.

The measuring device 12 is a portable ECG measuring apparatus which has a plurality of ECG electrodes 16 as sensors. As shown in the FIGURE, a patient 20 carries the ECG measuring apparatus 12 on his upper body, on which the ECG electrodes 16 are fastened. The ECG measuring device 12 has an ECG recorder for recording the ECG signals picked up via the ECG sensor 16. It also comprises a radio unit, with which it can build up a radio communication connection 26 with the measuring data detection device 24 for transmitting measuring signals.

To facilitate the correct placing of the ECG electrodes 16 on the upper body of the patient 20 for medical staff, the ECG measuring apparatus 12 has a three-colored LED 34 and a loudspeaker 30. The LED 34 and the loudspeaker 30 are used for optical or acoustic signaling of the quality of measuring signals which are captured via the ECG electrodes 16.

When the ECG measuring apparatus 12 detects that no measuring signal with adequate quality can be received via the ECG electrodes 16, it switches the color of the LED 34 to red to display a poor or lesser signal quality. Furthermore, an acoustic signal in the form of a short periodic audio signal sounds over the loudspeaker 30 for as long as the signal quality is not adequate.

The signal quality is checked fully automatically in the ECG measuring apparatus 12, as soon as it is switched on. It is also possible to start a test of the signal quality by actuating a signal quality test button 36 on the ECG measuring apparatus 12. This may be carried out, for example, by the patient 20 himself. When the signal quality is adequate, the ECG measuring device 12 transmits measuring signals of the ECG electrodes 16 via the radio communication connection 26 to the measuring data detection device 24 which shows the signals received, for example in the form of the curve pattern 42 on the large LCD display screen 38 and records the course of the measuring signals.

The measuring apparatus 14 is a pulsoximeter and connected to a pulsoximeter sensor 18, in which one finger 22 of the patient is located. The measuring signals of the sensor 18 are transmitted to the pulsoximeter measuring apparatus 14. The measuring apparatus comprises a comparator for comparing the signal quality of the measuring signals received with the predetermined threshold value for a predetermined signal quality. When the signal quality received is less than the predetermined threshold value, the comparator output signal activates an LED 32 and an audio signal generator which controls the loudspeaker 28 with an audio signal. In this case, there is therefore optical and acoustic signaling that the quality of the signal of the pulsoximeter sensor 18 is not adequate to ensure reliable recording in the measuring data detection device 24.

The signal quality can then be changed by the patient or medical staff by changing the position of the pulsoximeter sensor 18 in order to receive an adequate signal quality. When the signal quality is adequate, the measuring signals are transmitted from the pulsoximeter measuring apparatus 14 via a radio communication connection 26 to the measuring data detection device 24 which displays the measuring signals received in the form of numerical values on the screen 38 and records them.
