    • A patient ambulation motion detector is intended for attachment to a lateral generally vertical surface of a patient'body. The detector includes a motion sensor switch and a detachment detector switch which are mounted on a circuit board, the circuit board being in turn enclosed within an attachment casing which is attachable to a lateral surface of the patient's body. The motion sensor switch is a mercury switch mounted to the circuit board and having the axis of movement of the mercury contained therein oriented generally parallel to the circuit board so as to be responsive to declination of that portion of the patient's body to which the detector is attached and which declination is indicative of impending ambulation. The detachment detector switch is a spring contact switch which is openable and closable by a plunger acting thereon and sensitive to detachment of the detector from the patient's body. The detector may be wired to a conventional switched nurse call system.
    • 患者行走运动检测器旨在用于附接到患者身体的横向大致垂直的表面。 检测器包括安装在电路板上的运动传感器开关和分离检测器开关,电路板又被封装在可附接到患者身体侧面的附接壳体内。 运动传感器开关是安装在电路板上的水银开关,其中所含汞的运动轴线基本上平行于电路板定位,以便响应于检测器所在的患者身体部分的偏角 并且哪个倾斜表示即将来临的行动。 分离检测器开关是弹簧接触开关,其通过在其上作用的柱塞可打开和关闭,并且敏感地将检测器与患者身体分离。 检测器可以连接到常规的交换护士呼叫系统。
