Abstract

Abstract A machine for the treatment of infectious medical waste which eliminates sharps and the need for special waste handling and hauling. The waste enters hopper (13) and is chopped in chamber (15). A high phenol coefficient liquid is stored in container (28) and pumped into the cutting chamer (15). The chopped treated waste travels down chute (18) and is compacted in container (20). Additionally, all functions are interlocked with sensors (FIGS. 4A-C) to insure no waste passes through the machine without being treated.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 189 words
A machine for the disposal and treatment of infectious medical waste comprising: (a) cutting chamber; (b) said cutting chamber comprising rotating cutting blades of sufficient spinning velocity to cut metal and fibrous materials; (c) said cutting chamber being fed a fluid with a high phenol coefficient for sufficient quantity to render bacteria and viral infectious waste safe for common waste disposal practices; (d) said phenol fluid fed via a chemical dosing pump; (e) said cutting blades in said cutting chamber interlocked with a proximity sensor on a waste input door to insure machine operator safe from splashing or premature spinning of said cutting blades; (f) said cutting blades in said cutting chamber interlocked with a proximity sensor on a waste output door to insure operator will not come in contact with said infectious medical waste; (g) cutting blades interlocked with fluid flow sensors located in a phenol fluid flow tube to insure said infectious waste is treated for safe handling; (h) said cutting blades interlocked with fluid level sensors located at a base of a phenol fluid holding tank to insure said infectious waste is treated for safe handling.
Claim 2
Dependent Claim 189 words
