Title:
MEDICAL INSTRUMENT
Document Type and Number:
Japanese Patent JP3872190
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a medical instrument which makes information at the time of maintenance and check by storing a history in the case of the operation of shocking external force by means of a shock sensor when the power source of an instrument is in an off state and realizes cost down by providing one shock sensor with sensitivity with respect to external force operating in any direction.
SOLUTION: In the medical instrument incorporating the shock sensor 140 in transfusion pump 1 is arranged to tilt the sensitivity axis direction of the shock sensor 140 in a direction along an X-Z plane along the horizontal direction of the transfusion pump 1, in a direction along a Y-Z plane along the vertical direction of the pump 1 and in all the directions along a Y-X plane along the front/rear direction of the pump 1 to secure the sensitivity of shocking external force with respect to all the directions and to store detection even when the power source is in an off state at the time of detecting shocking external force not smaller than a prescribed value by the sensor 140.
