摘要： In a system of monitoring the blood pressure of a living body for an extended period of time, it is desired to alleviate the pain caused by pressure on the living body. The invention comprises a pulse wave detecting means for detecting pulse waves from the artery of a living body, a blood pressure measuring means for measuring the actual blood pressure of the living body, and a control means which finds a relationship between the pulse waves detected by said pulse wave detecting means and the actual blood pressure measured by the blood pressure measuring means, which determines the blood pressure based on the pulse waves and which continuously displays it on a display unit. From the relationship between the actual blood pressure found by the control means and the pulse waves, therefore, the blood pressure is determined on the basis of the pulse waves and is continuously displayed. Therefore, the blood pressure need not be continuously measured using a cuff, and the pain from which the living body suffers is greatly alleviated.

摘要： A noninvasive optical oximeter for measuring oxygen saturation of arterial blood. A sample of blood is illuminated with light at four different wavelengths. Light reflected by the blood is sensed by a photodetector and a plurality of output signals are created in response thereto. The reflected light at each of the four wavelengths is detected after contact with the blood and is correlated with the oxygen saturation of the patient's blood using mathematical relationships for arterial and venous oxygen saturation. The present invention provides a noninvasive backscatter oximeter which is capable of providing accurate indications of a patient's blood oxygen saturation without the need for obtaining prior information relating to the oxygen content of the patient's blood.

摘要： A compact, low noise inflation system for pressurizing occlusion cuffs used in conjunction with automatic blood pressure monitoring equipment. In the preferred embodiment, an electric pump is controlled by a closed-loop, pressure feedback control circuit which compares the cuff pressure with a desired pressurization profile set by the user or stored in a memory device. Acoustic filters are connected to the intake and exhaust ports of the pump to attenuate the intensity of acoustic noise and pressure waves to allow accurate detection of oscillometric pulse data by the blood pressure monitoring system.

摘要： A system for automatically positioning a blood pressure monitor transducer in a desired position relative to an underlying artery. The positioning system comprises a positioniong motor which drives a gear assembly. The gear assembly is operatively engaged with a lead screw having a follower mounted thereto in threaded engagement therewith. The follower is secured to a strap which is routed through a roller system. As the motor is activated in response to output signals from the sensor mounted within transducer housing, the lead screw will rotate, thereby effectuating lateral movement of the transducer housing and sensor along a path defined by the strap.

摘要： A cardiovascular monitor having improved safety features and data transmission ability. Sensing devices placed on a patient's body, such as electrocardiogram electrodes and phonocardiogram microphones, are electrically isolated from the data recorder and AC powerline, thereby protecting the patient from dangerously high voltages existing in the recorder and the external power source. Isolation amplifiers are employed in the signal conditioning circuitry at the front end of the recorder. Special isolation transformers are also used to prevent ground loop currents between the signal conditioner and the recorder thus minimizing noise due to powerline leakage. Similarly, isolation amplifiers are used during the playback mode between the recorder and a data processor to avoid ground loop currents between the recorder and the processor.

摘要： An automatic blood pressure measuring apparatus including an occluding device having a cuff to apply a pressure to a body member of a subject, and a blood-pressure determining device to determine a blood pressure according to a variation in a pulse wave in relation to a change in the cuff pressure. The apparatus comprises a detector for monitoring a blood circulatory system of the subject, and generating signals representing an abnormality associated with the circulatory system. The apparatus further comprises a control device for actuating the occluding device to apply the cuff pressure to the body member, and causing the blood-pressure determining device to execute a predetermined series of blood-pressure measuring steps to measure the blood pressure, thereby permitting an automatic measurement of the blood pressure of the subject when the blood circulatory system is found abnormal by the detector.

摘要： A cuff mechanism for use with a blood pressure measuring apparatus which comprises a flexible band, accommodating a cuff within the same wrappable (windable) in a cylindrical roll about an arm of a human body, and an air cylinder as a pulling means for pulling the band to tightly compress the band about the arm operated by pressurized air supplied in common with an air bag disposed in the band from an air supplying means. The flexible band is provided with, on occasion, a plurality of cross cuts formed on both sides thereof for better adaptation to the shape of an arm, and the air cylinder is sometimes pivoted to a stationary member swingably with a pin for being variable in the pulling direction of the band for better adaptation of the band to an arm of ununiform thickness and of irregular surface.

摘要： A method and apparatus for detection of coronary artery disease. The apparatus records and analyzes that portion of the phonocardiogram lying between about 100 to 600 Hz. An electrocardiogram is also recorded and examined in order to pinpoint the diastolic window of PCG data. This window of data is subject to autocorrelation analysis and spectral analysis, resulting in a partial correlation coefficient index and a power density index. A linear combination of these two indices results in a Cardiac Screening Index which is indicative of the presence or absence of coronary artery disease.

摘要： An improved optical sensor which has increased sensitivity and which is resistant to the effects of ambient light. In one embodiment of the invention, the sensor housing has a flat lower face with a central protrusion in which a plurality of light emitting diodes and an optical sensor are mounted. When the sensor is placed on the patient's tissue, the portion of the sensor face containing the LEDs and detector protrudes slightly into the tissue to provide improved optical coupling of the sensor to the skin. A light absorbing compliant material is attached to the perimeter of the sensor to reduce the effects of ambient light and to provide a cushion to minimize discomfort to the patient. In an alternate embodiment of the sensor, the LEDs and detector are mounted in a horizontal configuration substantially parallel to the surface of the tissue. The light produced by the LEDs is projected into a central chamber of the housing where the respective beams are combined and directed toward the tissue. In this emodiment, the desired combining of the beams can be achieved through the use of a set of mirrors or a prism. Various combinations of the improvements provided by each of the embodiments described above can be incorporated into either a transmission or backscatter optical sensor to provide a compact, sensitive optical sensor which is resistant to interference caused by ambient light.

摘要： An inflation system for providing rapid, linear inflation of a container, such as an occlusion cuff used in connection with a blood pressure monitoring system. The invention system provides an automatic fast-fill of the cuff to a predetermined pressure level, followed by a smooth, linear pressurization profile which is independent of the volume of the cuff. An efficient electronic actuation system allows the system to inflate the cuff many times using the power supplied by a low power battery. A pressure relief system is provided to automatically terminate operation of the inflation system once systolic pressure has been detected or if the pressure in the system rises above a predetermined level. The system is extremely lightweight and compact, thus allowing a patient to carry the system on his person without undue fatigue.
