    • Apparatus is described for measuring both the systolic and diastolic blood pressure of an individual. A pressurable cuff having an additional tightening band for advantageously positioning a cuff and microphone on an artery is described. The microphone is connected to first the second filters having respective passbands for analyzing the frequency content for recovered pulse signals. The apparatus provides for automatic pressurizing and depressurizing of the cuff whereby the artery is occluded and opened to permit passage of the blood flow. The pressure at the time of receipt of signals from the filters is measured as the systolic pressure. The diastolic blood pressure is measured with apparatus in accordance with the invention by monitoring signals from one of the filters.

    • A sphygmomanometer is provided with an automatic pressure inflation and deflation means for feeding a pressurized air into a cuff wound on the upper arm or the like so as to close the arterial blood flow. Korotkoff's sounds are detected during an interruption of the pressurized air feeding. The air is intermittently repressurized so long as the Korotkoff's sounds can be detected, and is switched over to an exhausting state when the Korotkoff's sounds are no longer detected. The systolic/diastolic blood pressure values are detected during the exhausting state and are digitally indicated. A continuous sound is generated until the Korotkoff's sounds reappear, and thereafter a sound is generated which is synchronized with Korotkoff's sounds.
    • 血压计设置有自动压力充气和放气装置,用于将加压空气供给到缠绕在上臂等上的袖带中,以封闭动脉血流。 在加压空气供给中断期间检测到Korotkoff的声音。 只要可以检测到Korotkoff的声音,空气被间歇地加压,并且当Korotkoff的声音不再被检测到时,空气被切换到疲劳状态。 在排气状态下检测收缩压/舒张压值,并进行数字显示。 直到Korotkoff的声音再次出现才产生连续的声音,此后产生与Korotkoff声音同步的声音。

    • A fluid pump has a pumping member which defines the boundary of a pump chamber and is driven to reciprocate between the positions of expanding and contracting the pump chamber for drawing in the pump chamber a fluid and feeding it into a vessel to be pressurized thereby. The pumping member is connected to the output shaft of a reversible motor through a driving linkage capable of translating the rotary motion of the output shaft into the reciprocating motion of the pumping member. A release valve is provided in a fluid path between the pump chamber and the vessel for rapidly releasing the pressurized fluid out of the vessel. The release valve is operatively connected to the motor output shaft through a release valve actuator which responds to the reversal of the motor for opening the release valve and has a delay mechanism providing a delayed response action in opening the release valve so that the initiation of opening the release valve is inhibited until the output shaft rotates in the reverse direction through an angle of more than 180 degrees from the reversing point, thereby inhibiting an unintended opening of the release valve due to the reverse translation of the reciprocating motion of the pumping member because of kickback by pressurized fluid in the pump chamber when the motor is stopped.
    • 流体泵具有泵送构件,其限定泵室的边界并且被驱动以在泵室膨胀和收缩的位置之间往复运动,以在泵室中抽吸流体并将其输送到容器中以被加压。 泵送构件通过能够将输出轴的旋转运动转换成泵送构件的往复运动的驱动联接器连接到可逆电动机的输出轴。 释放阀设置在泵室和容器之间的流体路径中,用于将加压流体快速地从容器中释放出来。 释放阀通过释放阀致动器可操作地连接到电动机输出轴,释放阀致动器响应于马达的反转以打开释放阀,并具有延迟机构,其在打开释放阀时提供延迟的响应动作,使得开启 释放阀被禁止,直到输出轴沿相反方向从反转点旋转大于180度的角度,从而由于泵送构件的往复运动的反向平移而禁止释放阀的意外打开,因为 当电机停止时,通过泵室中的加压流体回引。
