Patient weighing scale with hoist

摘要

The present patient weighing scale provides an automatic display of the patient's weight in digital form. For this purpose, a stretcher is secured to a cantilever boom through supporting means including two beam type transducers, for example double bending beam transducers, responsive to vertical forces and located in the respective ends of a tubular crossbar. The tubular crossbar is one element in a chain of supporting elements between trhe stretcher and the cantilever boom. The supporting elements include preferably pivots or bearings arranged so that the forces resulting from the weight of the patient extend in parallel to the direction of gravity whereby the transducer measuring axis always coincides with the direction of the gravity vector independently of the boom angle.
