Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A patient weighing device which comprises, in combination, a bed having four legs, an individually removable weight detecting element disposed under each of said legs for supporting the bed, each of said removable weight detecting elements having an upper layer, a middle layer and a lower layer, said upper layer having a concave indentation and providing a load concentrating surface, said middle layer comprising pressure weight measure means and said lower layer comprising a support surface, said removable weight detecting elements each in communication with a counting and indicating device for identification of weight of the bed detected by the weight detecting elements under the bed legs.
Claim 2
Dependent Claim
107 words
A patient weighing device which comprises, in combination, a bed having four legs, an individually removable weight detecting element disposed under each of said legs for supporting the bed, each of said removable weight detecting elements having an upper layer, a middle layer and a lower layer, said upper layer having a concave indentation and providing a load concentrating surface, said middle layer comprising pressure weight measure means and said lower layer comprising a support surface, said removable weight detecting elements each in communication with a counting and indicating device for identification of weight of the bed detected by the weight detecting elements under the bed legs.
Claim 3
Dependent Claim
