DE2359740A1 - Patient surveillance indicator system - uses one numerical indicator for various measurements having set threshold valves - Google Patents

Abstract

Automatic patient surveillance system makes use of only one numerical indicator for the various measurements for which thresholds are indicated or adjusted. A switch provided for a respective adjusting member for a particular threshold is connected such that the set value of the threshold indicated. The various measurements can relate to arterial and veinous blood pressures, pulse rate etc. in, for example, an intensive care unit. Further functions can be installed such as recorded indications for the values exceeding the threshold values to save frontage space and confusion through dealing with too much information at once. Especially significant indications can be set to blink.

Device for the automatic monitoring of systems, especially for patient monitoring

The invention relates to a method and a device for automatic monitoring of the status of systems, in particular of patients in e.g. an intensive care unit.

The automatic monitoring of such patients in a more or less dangerous condition usually takes place in that on the patient's bed and / or in the monitoring center or a lounge of the nursing staff a warning signal is triggered, which indicates the exceeding or falling below one or more preselected upper or lower limit values of various physiological values measured on the patient Variables (e.g. arterial and venous blood pressure, pulse rate, rectal temperature, etc.) through the relevant measured variables make and cause the nursing staff to intervene. Each individual limit value overshoot or undershoot can also trigger automatic therapeutic measures or influence their triggering.

For automatic determination of exceedance or undershoot Preselected limit values, it is common to measure the respective measured variable with a pointer instrument, i.a. an (electric moving-coil instrument to display and the pointer position of this Instrument to be monitored by adjustable sensors (i.e. so-called. To use measuring mechanism controller). With other methods, the setting of the limit values is carried out on potentiometers provided with scales made or the setting of the potentiometer e.g. by the location of luminous pointers displayed on the screen of a cathode ray tube. The overshooting or undershooting of the limit value is then monitored electronically by comparators.

The disadvantage of this method is that it is permanent display each individual limit value require a display device, but at least a special scale. That is expensive and

above all demands a lot of space on the front panel of the or the monitoring equipment.

The inventive method for setting and monitoring of limit values avoids these disadvantages in that only a single display device is used to set the limit values which, when a switch or pushbutton is assigned to the respective setting element is actuated, the set limit value and after setting the limit value (s) for other display tasks (see e.g. patent application P 22 49 511.0 from 10.10.72) is available.

The display device common to all limit value setting devices can be used to support the operating personnel in addition to the corresponding Amount also show the measured variable (e.g. arterial pressure) and the dimension of the amount (e.g. mmHg) (when using a Multiple display according to P 22 49 511.0, this is done informally and without additional effort).

The switch, which must be operated to connect the display device to the respective limit value setting element, can have a further function: It can also be used to switch off the warning signal or a (stored) display that the limit value has been exceeded. As a result, further front panel area can be saved and the large number of control elements - which is mostly confusing for the operating personnel - can be reduced.

The display device can also be used for exceeding or falling below of a preset limit value to automatically display the measured variable which exceeds one of its limit values. or has fallen below. In order to emphasize this fact particularly clearly, the display (if it is is an electronic numeric display) flashing on and off; it indicates that it is automatic has switched to the critical measured variable.
