Abstract: There is provided a vital information processing apparatus capable of effectively reducing small-amplitude noise and isolated noise without degrading an abrupt change portion in a processing target vital signal. A vital signal detected by a vital signal detector (10) is input from a vital signal input unit (20). A sync signal extractor (25) extracts, e.g., the QRS wave form of an electrocardiogram signal of the input signal and outputs the extracted wave as a sync signal (26). A preprocessor (30) performs predetermined preprocessing for the processing target vital signal, e.g., a K sound signal and outputs the preprocessed signal to median filters (40, 45). Each of the median filters (40, 45) filters the Korotkoff sounds using the QRS signal (26) as the index value and outputs the resultant signal.

Abstract: In medical facilities in which medical treatments are performed at a plurality of locations, the state of a patient can be continuously and time-serially determined even if the location at which the medical treatment is given changes. Patient information collection systems for collecting medical treatment results of patients are installed in a plurality of locations where medical treatments are performed. A server system (800) capable of receiving information from each system and storing patient information is arranged. Every time the patient is moved from one room to another room, the destination is sent to the server system (800), and the server system can trace and store the patient information. Data collected from a patient and to be sampled and stored are temporarily displayed and confirmed by a physician or the like, and the confirmed data are specified as sampled data.

Abstract: A method and apparatus for recording electrocardiogram information, in which ST deviation can readily be visualized and ischemia can be diagnosed with ease at the same time. Compressed recorded waveforms of electrocardiogram waveforms are partitioned and recorded as compressed waveforms of a plurality of lines in a first recording area of a recording paper for recording electrocardiogram information. A predetermined number of lines of the recorded compressed electrocardiogram waveforms in the first recording area are selected in a second recording area neighboring the first recording area, the selected waveforms are superimposed in synchronism with a predetermined characteristic point of the selected waveforms, and the waveforms are recorded while changing location in the area neighboring the predetermined lines of the first recording area.

Abstract: It is an object to project an alarm display device from a retracted position in the body of a biological information processing apparatus when it is determined that such a display is necessary according the results of date processed. The alarm display unit is set on the upper part of the apparatus. It is engaged to an enclosure so that there are two states; retracted/stored and projected. This alarm display unit comprises four alarm display devices, set in a line on the tip of the projected alarm display unit, which perform the displays indicating emergency in the case where it is projected. The alarm display unit is automatically projected when emergency has occurred on the subject and the condition is displayed by the alarm display device.

Abstract: An electrocardiographic waveform recorder, analyzer, printer and display for superimposing in synchronization, for a predetermined period of time, ECG waveforms. The waveforms are superimposed and synchronized with a predetermined characteristic ECG point (the R-wave peak point) and a plural number of waveforms are expressed while the superimposed positions, at which they are expressed, is changed at fixed intervals of the waveforms, permitting state of deviation recognition.In addition, an ST trend graph and a heart rate output are used for comparisons with environmental conditions. Also, data is recorded continuously over time and displayed and printed at intervals corresponding to the occurrence of the characteristic point of the waveform which permits change in the superimposed waveform display positions. A P wave, a T wave and a QRS wave can be extracted, along with their crest values and the crest value at an arbitrary position in an ST region.

Abstract: An electrode and a lead wire therefor used with a device for measuring the electrical signals emanating from a living body, such as a cardiograph or electroencephalograph employed for examination and diagnostic purposes. The electrode consists of two layers of finely divided electrically conductive material, that are printed in laminated fashion on the opposite surfaces of an insulating film. The lead wire comprises plural laminated layers of finely divided electrically conductive material on the opposite sides of an insulating film, the laminated layers being interspersed with or encased by carbon layers and insulating layers. Since X-rays penetrate the electrode and the lead wire, an X-ray photograph may be taken during visual inspection of the biosignals without the image of the electrode and the lead wire appearing on the film to hinder diagnosis.
