In-bed patient scale
First Claim
1. A scale system for measuring the weight of a person supported on a bed frame which can have plural articulatable sections, the scale system comprising:
- (a) a load assembly mountable on a bed frame and having length and width dimensions related to length and width dimensions of the frame, the load assembly comprising plural planar and substantially rigid load receivers which are sized for accommodation of bed frame articulation, the load assembly having a height dimension which is small relative to its width and length dimensions whereby the presence of the load assembly in association with a mattress on the bed frame does not appreciably raise the mattress above the frame,(b) a plurality of load sensors disposed at selected locations in the load assembly each having an output signal representative of the load carried by the assembly in the vicinity of the sensor, and(c) a system output device operable for receiving the several sensor output signals and for producing a system output signal which is representative of the total load carried by the load assembly.

Abstract
A scale disposable on a bed frame for measuring the weight of a person in the bed on a mattress, the scale comprising a relatively thin scale frame assembly having overall length and width dimensions related to the dimensions of the bed frame. A plurality of load cells are carried by the scale frame assembly at selected locations in the assembly, each cell producing a signal representative of the weight applied to the frame assembly in its vicinity. A scale control and display device receives the several load cell signals and produces a scale output signal indicative of the weight of a person supported on the mattress.

16. A scale system for measuring the weight of a person supported on a bed frame which can have plural articulatable sections, the scale system comprising:
-
(a) A load assembly mountable on a bed frame and having length and width dimensions related to length and width dimensions of the frame, the load assembly comprising plural planar and substantially rigid load receivers which are sized for accommodation of bed frame articulation, the load assembly having a height dimension which is small relative to its width and length dimensions whereby the presence of the load assembly in association with a mattress on the bed frame does not appreciably raise the mattress above the frame, b) a plurality of load sensors disposed at selected locations in the load assembly adjacent each longitudinal edge of the load assembly in an array in which the sensors are disposed in pairs with each sensor adjacent one edge being opposite a corresponding sensor adjacent the opposite load assembly edge, each having an output signal representative of the load carried by the assembly in the vicinity of the sensor, and c) a system output device operable for receiving the several sensor output signals and for producing a system output signal which is representative of the total load carried by the load assembly. - View Dependent Claims (17, 18, 19, 20, 21)
