Patent ID: 8562916

Claim:
A medical wastes disposal apparatus comprising: a gate including heating means and opening and closing means on a housing lower portion of a vertical-type cylindrical-shaped housing opened at both upper and lower ends thereof, a piston including heating means and compression means based on ascent and descent on an upper portion of the housing, a hatch including opening and closing means for opening and closing of a side opening provided on a side of the housing, a drain-board arranged below the gate on the lower portion of the vertical-type cylindrical-shaped housing to receive cake obtained by melt sterilization and volume reduction of medical wastes with heating compression and a push plate tightly joined to the gate to enable maintaining a predetermined spacing between the push plate and the drain-board and wherein cake dropping upon opening of the gate can be automatically discharged outside by the push plate tightly joined to the gate when the gate is closed, and a side hole provided on the lower portion of the vertical-type cylindrical-shaped housing and a fork mechanism provided with drawing and entering means, which is capable of drawing out of and entering into the side hole and wherein when a polypale or cans in which medical wastes are received, are fed from the side opening on the side of the vertical-type cylindrical-shaped housing, a fork of the fork mechanism is caused to advance into an interior of the housing to receive the polypale or cans on the fork, and after the hatch for the side opening is closed, the fork is caused to retreat to enable loading the polypale or cans on the gate, which is disposed on the housing lower portion, without tipping, wherein when a polyethylene bag with medical wastes received therein is supplied to the cylindrical-shaped housing and the compression means lowers the piston to compress the medical wastes, the piston is repeatedly caused to go up and down for stepwise compression whereby the polyethylene bag with medical wastes received therein is prevented from entering into a clearance between an inner wall of the cylindrical-shaped housing and the piston and from bursting due to rapid compression, and when a cake obtained by melt sterilization and volume reduction with heating compression is discharged, the gate is fully opened to lower a lower surface of the heating means of the piston to a point adjacent to an upper surface of the heating means of the gate and the gate is closed to enable forcibly scraping off the cake adhering to the heating means tightly joined to the piston.
