A biological information measurement device according to the present invention detects a signal expressing biological information from a fingertip using an internal sensor (S). A first perfusion index and first biological information aside from the first perfusion index are obtained from the signal detected by the internal sensor (S, S). It is determined whether or not the first perfusion index is greater than or equal to a first threshold (S). When the first perfusion index is greater than or equal to the first threshold, the first biological information is permitted to be displayed in a display unit (S). However, when the first perfusion index is less than the first threshold, a notification is made indicating that an external sensor that is lighter than a main body, is an entity separate from the main body, and is communicably connected to the main body is to be used (S).

Biological information measurement device

A portable electrocardiograph having a display function and method is disclosed. In measuring an electrocardiographic waveform, an electrocardiograph () is held in position by a grip including a negative electrode () while simultaneously pressing a contact section including a positive electrode () against an electrode contact portion other than the right hand of the subject. The measurement result is displayed on a display unit () during the measurement operation. The measurement method is divided into the induction mode I in which the contact section including the positive electrode () is pressed against the subject's left hand, and the induction mode II in which the contact section including the positive electrode () is pressed against the subject's lower left abdomen. In induction mode I, the measurement result is displayed horizontally on the display (), while in the measurement in mode II, the measurement result is displayed vertically.

Electrocardiograph and display method for electrocardiograph

A portable electrocardiograph and method of use are disclosed. According to one aspect of the present invention, a portable electrocardiograph is provided which includes: a rectangular housing having at least a first outer surface and a second outer surface; a first electrode provided on the first outer surface of the housing; an electrode formation face provided on the second outer surface of the housing; and a second electrode provided within the electrode formation face; wherein the electrode formation face includes an electrode region in which the second electrode is positioned and a non-electrode region which is positioned so as to surround the electrode region.

Portable electrocardiograph

The thermometer includes an oscillation unit having a time constant circuit with a compound resistor including a reference resistor and a temperature sensitive resistor. The compound resistor is switched between the reference and temperature sensitive resistors. A comparator compares the oscillation frequencies of the oscillation unit by switching over the compound resistor between the reference and temperature sensitive resistors at a variable sampling interval, and outputs digital data corresponding to the temperature sensed by the temperature sensitive resistor. The digital data corresponding to the sensed temperature are converted and displayed on a temperature data display unit. The resistive value of the reference resistor and the sampling time are switchable according to the range of temperature measurement. The temperature data conversion unit has several sections which are switchably selected according to particular ranges of temperature measurement. Each of these temperature data sections, upon receipt of the digital data from the comparison unit, outputs appropriate temperature data according thereto. A switching unit switches between the various sections of the temperature data conversion unit. A switching control device, in response to the output of the temperature data conversion unit, determines the range of temperature measurement, and appropriately controls the switching actions of the reference resistor, the sampling time switching unit, and the temperature data conversion means switching unit.

Electronic thermometer with multi range measurement capability

An electronic thermometer of the present invention includes: a temperature sensor for sensing temperature and outputting a digital signal value representative thereof; a temperature conversion data storage unit having at least a first data storage area for storing temperature conversion data of relatively high resolution and a second data storage area for storing temperature conversion data of relatively low resolution; a read-out element for, when the digital signal produced by the temperature sensor is within a first range, reading-out corresponding temperature conversion data from the first data storage area according to the value of the digital signal, and, when the digital signal, produced by the temperature sensor is within second range, reading out corresponding temperature conversion data from the second data storage area according to a selected value of the digital signal, and a display for displaying a temperature corresponding to the temperature conversion data. Whereby, when the temperature is in the first range, high resolutions and high accuracy of indication can be obtained while when the temperature is in the second range, low resolution which may be quite acceptable may be attained. Thereby, the capacity of the temperature conversion data storage unit may be more economically effectively utilized.
