Bed apparatus having movable bedboard

A body weight threshold determination unit determines that the body weight of a user on a bed is at a body weight threshold or higher, and a center-of-gravity position area determination unit determines that the center-of-gravity position thereof has moved to an abnormal position (monitored area). In such a case, the bed user is detected to be in an abnormal position when a body weight center-of-gravity position monitoring unit detects that such a state has continued for a prescribed length of time or longer. When a back-raising operation has been carried out, a movable bedboard determination unit inputs the movable bedboard information, and a monitored area adjustment unit adjusts the monitored area. The monitored area is thereby constantly set to a suitable area in accordance with the state of the movable bedboard. In this manner, the combined information of the body weight information and center-of-gravity position information of the user is determined, whereby the movement of the user can be more accurately monitored with fewer misdetections, high detection accuracy, and high reliability in an electric bed having a movable bedboard.

Leak detector for detecting leak of liquid injected into blood vessel using pulse signal

A leak detector sequentially emits pulse signals toward a human body at a position at which a needle is inserted, detects pulse signals reflected inside of the human body, and measures a time interval between the emission and the detection for each of the pulse signals. Then, the leak detector calculates the difference between the measured interval and a predetermined time interval, and generates a leak warning for notification when the difference exceeds an acceptable range. Since a swelling on the surface of the human body causes a path of the pulse signal to extend, the leak detector can detect, based on the extended signal path, that the needle has come off a blood vessel.
