Abstract: Blood pressure values measured in four limbs are plotted on first to fourth linear axes which extend from an origin in an upper right direction, an upper left direction, a lower left direction, and a lower right direction respectively, and a rectangle composed of vertices which are determined by the plotted blood pressure values is illustrated to present the blood pressure values. This allows a specific measured value in each site to be easily known, and the relationships between the blood pressure values in the four limbs are intuitively understood from the shape of the rectangle.

Abstract: To disclose a biomedical signal processor with a simple configuration and a minimum space capable of confirming an operating condition and a signal collection state of the biomedical signal processor such as an electrocardiograph. As an example of the biomedical signal processor according to the present invention, a Holter electrocardiograph supplies biomedical signals to a light-emitting element (LED) 30 and applies a bias supply voltage from a power supply section 80 to the LED 30. By setting a bias voltage to a voltage so that a level of a minimum supply voltage to the LED 30 becomes a positive potential when electrocardiogram signals are input to an input amplification section 10, the LED 30 turns OFF when power is turned OFF, becomes half-lit when power is turned ON and its luminescence intensity is variable when signals are collected normally, making it possible to easily check a state of the apparatus.

Abstract: A biomedical signal cable that is applicable to also serving as an antenna for radio transmissions. The biomedical signal cable is a connects a medical telemetery having a radio transmission function and a biomedical electrode and places a selective high-resistance body with respect to a radio signal at a position away from a base of the signal cable by approximately a ¼ wavelength of the transmission frequency of the medical telemetery.

Abstract: The present invention provides a telemeter for medical care to determine position information of a patient in a narrow range in the following manner. Position information transmitters using electromagnetic induction radio are arranged at necessary positions in a medical facility, and a receiver for receiving position information is built in the telemeter for medical care carried by each of patients. The position information is superimposed on a signal transmitted by the telemeter transmitter for medical care and a receiving device receives the position information together with the living body information of the patient. Further, the past position information of the patient is stored and compared with the present position information of the patient.

Abstract: To disclose a biomedical signal cable ideally applicable to also serving as an antenna for radio transmissions. The biomedical signal cable according to the present invention is a biomedical signal cable that connects a medical telemetery having a radio transmission function and a biomedical electrode and places a selective high-resistance body with respect to a radio signal, for example, a ferrite core 120 at a position away from a base 110 of a signal cable 100 by approximately a ¼ wavelength of the transmission frequency of the medical telemetery. In this way, the present invention makes a high frequency signal produce resonance, thereby improving an antenna efficiency of the biomedical signal cable.

Abstract: An apparatus for alerting a doctor which provides an alarm corresponding to a patient, and receives living body information signals transmitted through a transmitter. The apparatus alerts a doctor with a buzzer sound or a vibration indicating that the condition of the patient and of the living body information signals has changed suddenly. The apparatus includes a portable casing having a front plate, a rear plate, a top plate, a bottom plate, a left plate, and a right plate. The casing is provided with a circuit plate on which an electric circuit is mounted which receives and treats the living body information signals. Moreover, the apparatus is provided with a display portion provided on the casing and connected with the electric circuit. The wave form of at least an electrocardiogram signal included in the living body information signals is displayed on the display portion.

Abstract: A breathing detection air bag is disclosed, which includes an air bag and a detector. The air bag includes a sponge body capable of being expanded and contracted with contraction and expansion of a pectoral or abdominal part of a person, a sponge cover enclosing the sponge body for preventing air contained in the pores of the sponge body from escaping from the pores, and a flange provided integrally with the edge of the sponge cover and an air guide tube for guiding an air stream caused by the expansion and contraction of the sponge body.
