Abstract

Abstract An automatic blood pressure measuring apparatus including an occluding device having a cuff to apply a pressure to a body member of asubject, 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.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 177 words
An apparatus for automatically measuring blood pressure of a living subject, including an occluding device (22) having a cuff (10) for applying a pressure force to a body member of the subject; and blood-pressure determining means (S3) for determining the blood pressure according to a variation in a pulse wav generated at the body member in relation to a change in the pressure force applied thereto by the occluding device, characterized by comprising: abnormality detecting means (34, 60) for monitoring a blood circulatory system of said subject for normal functioning thereof, and generating abnormality signal representing an abnormality associated with said blood circulatory system; control means (50, 52, 54), responsive to each of said abnormality signal, for actuating said occluding device (22) to apply said pressure force to said body member, and causing said blood-pressure determining means (S3) 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 said abnormality detecting means.
Claim 2
Independent Claim 177 words
An apparatus for automatically measuring blood pressure of a living subject, including an occluding device (22) having a cuff (10) for applying a pressure force to a body member of the subject; and blood-pressure determining means (S3) for determining the blood pressure according to a variation in a pulse wav generated at the body member in relation to a change in the pressure force applied thereto by the occluding device, characterized by comprising: abnormality detecting means (34, 60) for monitoring a blood circulatory system of said subject for normal functioning thereof, and generating abnormality signal representing an abnormality associated with said blood circulatory system; control means (50, 52, 54), responsive to each of said abnormality signal, for actuating said occluding device (22) to apply said pressure force to said body member, and causing said blood-pressure determining means (S3) 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 said abnormality detecting means.
Claim 3
Dependent Claim 39 words
An apparatus as recited in claim 1, wherein said abnormality detecting means comprises at least one electrode (38) attachable to a cuticle of the subject and detecting a variation in electromotive force to detect heart beats of the subject.
Claim 4
Dependent Claim 60 words
An apparatus as recited in claim 2, wherein said abnormality detecting means (34) comprises means (40, 44, 46) for obtaining a number of said heart beats per unit time, and generating a beat-number abnormality signal representing an abnormality associated with said number of the heart beats when said number of the heart beats does not fall within a predetermined range.
Claim 5
Dependent Claim 47 words
An apparatus as recited in claim 2, wherein said abnormality detecting means (34) comprises means (42, 48) for obtaining an interval of said heart beats, and generating an arrhythmia signal representing an arrhythmic condition of the heart when said interval does not fall within a predetermined range.
Claim 6
Independent Claim 52 words
An apparatus as recited in claim l, wherein said abnormality detecting means (60) comprises a photoelectric device (76, 78, 80) which senses a variation in amount of light transmitted through a finger tip of the subject and detects a blood pulse wave corresponding to a blood flow pulsation in the finger tip.
Claim 7
Dependent Claim 57 words
An apparatus as recited in claim 1, wherein said abnormality detecting means (60) has plural electrodes (84) adapted to be held in contact with a finger of the subject and sensing a variation in impedance of the finger, said abnormality detecting means (60) detecting a blood pulse wave corresponding to a blood flow pulsation in the finger.
Claim 8
Dependent Claim 65 words
An apparatus as recited in claim 5 or 6, wherein said abnormality detecting means (60) comprises means-for determining a volume of a blood flow in the finger based on an amplitude of said blood pulse wave, and generating a blood-insufficiency signal (SB) representing insufficiency of the blood flow when a rate of decrease in said amount of the blood flow has exceeded a predetermined value.
Claim 9
Independent Claim 103 words
An apparatus as recited in any one of the preceding claims 1-7, further comprising: another abnormality detecting means (R6) for judging that the blood pressure determined by said blood-pressure determining means is abnormal, when the determined blood pressure does not fall within a predetermined range; and % an abnormality indicator (56) providing a concurrent indication of said abnormality associated with said blood circulatory system and of an abnormality of the blood pressure, when said abnormality signal is generated from said abnormality detecting means (34, 60) and when said determined blood pressure is judged to be abnormal by said another abnormality detecting means (R6).
Claim 10
Dependent Claim 81 words
An apparatus as recited in claim 8, wherein said abnormality indicator (56) provides a concurrent indication of an abnormality associated with said heart beats and of the abnormality of the blood pressure, when an abnormality associated with number of the heart beats per unit time and/or an abnormality associated with an interval of the heart beats is/are detected by said abnormality detecting means (34) and when the abnormality of the blood pressure is detected by said another abnormality detecting means (R6).
Claim 11
Dependent Claim 69 words
An apparatus as recited in claim 8, said abnormality indicator (56) provides a concurrent indication of insufficiency of a blood flow in a finger of the subject, and of the abnormality of the blood pressure, when a decrease in volume of said blood flow is detected by said abnormality detecting means (60) and when the abnormality of the blood pressure is detected by said another abnormality detecting means (R6).
Claim 12
Dependent Claim 119 words
An apparatus as recited in claim 3, further comprising: another abnormality detecting means (R6) for sensing blood pulses at said body member occluded by said occluding means (22), counting a number of said blood pulses per unit time, and judging that the counted number of the blood pulses is outside a predetermined range; and an abnormality indicator (56) providing a concurrent indication of the abnormality associated with the number of the heart beats, and of an abnormality associated with said counted number of the blood pulses, when both of said abnormalities associated with said numbers of the heart beats and the blood pulses are detected by said abnormality detecting means (34) and said another abnormality detecting means (R6), respectively.
