Abstract
A surgery table load monitoring system utilizing a base member fixed to a surgery table support. The base member is connected to at least one platform structural member to determine load forces due to the weight of a patient on the platform structured member. Detectors are used to indicate particular stresses and generate a signal which may be employed to disable movement of the surgery table.
Claims15
An apparatus for monitoring forces applied to a medical table, comprising:
- a patient support;
- a base member, said base member being directly connected to said patient support of the medical table structure, said base member;
- at least a first strain gauge and a second strain gauge, said first and second strain gauges being mounted on said base member, said first strain gauge possessing a different strain direction from said second strain gauge, said first strain gauge detecting the quantity of a first force on said base member deriving from movement of said base member in a first direction by said connected patient support, said second strain gauge detecting the quantity of a second force on said base member, deriving from movement of said base member in a second direction by said connected patient support, said first and second strain gauges generating first and second output signals, respectively;
- a motor mechanism directly connected to said base member, said motor mechanism positioning said base member and said connected patient support;
- and
- a controller, said controller receiving said first and second output signals from said first and second strain gauges, respectively, and determining the functioning of said motor mechanism.
