Abstract
Abstract A cold sterilization unit comprises an open-topped tank having a closure lid hingedly attached thereto. An insert tray is disposed within the tank, and linkage means interconnect the tray to the lid to effect movement of the tray with movement of the lid. The linkage means includes means operative to lift the tray upwardly in substantially horizontal position, out of a sterilization liquid within the tank, during initial opening of the lid, and then operates to effect a tilting of the tray to an angular position during further opening of the lid beyond the predetermined opening position to effect a gravity dumping of implements in the tray into a collection receptacle which removably engages the tray.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
254 words
A cold sterilization unit comprising an open-topped tank adapted to contain a sterilizing liquid bath therein, a closure lid hingedly attached to said tank for closure thereof, a perforated insert tray disposed in said tank, said perforated insert tray having a perforated collection receptacle removably attached thereto, both said tray and said attached collection receptacle being adapted to be substantially fully immersed in said bath when said closure lid is in closed position, connecting means interconnecting said tray to said lid to effect movement of both said tray and its attached collection receptacle with movements of said lid, said connecting means including means operative to lift said tray and its attached collection receptacle upwardly in substantially horizontal position to a position above the normal surface level of said bath during initial opening of said lid thereby to effect a drainage of liquid via said perforated insert tray into said bath, said connecting means being further operative to effect tilting of said tray and its attached collection receptacle to a position angularly inclined to horizontal and located above the normal surface level of said bath during further opening of said lid beyond a predetermined opening position thereby to effect a gravity dumping of implements in said tray toward said collection receptacle and to effect further drainage of liquid into said bath via the perforations in said collection receptacle, whereafter said collection receptacle may be detached from said insert tray to permit the removal of instruments from said sterilization unit without manual handling of said instruments.
Claim 2
Dependent Claim
254 words
A cold sterilization unit comprising an open-topped tank adapted to contain a sterilizing liquid bath therein, a closure lid hingedly attached to said tank for closure thereof, a perforated insert tray disposed in said tank, said perforated insert tray having a perforated collection receptacle removably attached thereto, both said tray and said attached collection receptacle being adapted to be substantially fully immersed in said bath when said closure lid is in closed position, connecting means interconnecting said tray to said lid to effect movement of both said tray and its attached collection receptacle with movements of said lid, said connecting means including means operative to lift said tray and its attached collection receptacle upwardly in substantially horizontal position to a position above the normal surface level of said bath during initial opening of said lid thereby to effect a drainage of liquid via said perforated insert tray into said bath, said connecting means being further operative to effect tilting of said tray and its attached collection receptacle to a position angularly inclined to horizontal and located above the normal surface level of said bath during further opening of said lid beyond a predetermined opening position thereby to effect a gravity dumping of implements in said tray toward said collection receptacle and to effect further drainage of liquid into said bath via the perforations in said collection receptacle, whereafter said collection receptacle may be detached from said insert tray to permit the removal of instruments from said sterilization unit without manual handling of said instruments.
Claim 3
Dependent Claim
101 words
The unit of claim 1 wherein said perforated collection receptacle comprises a basket having walls adapted to overlie and to removably engage walls of said tray adjacent and along a forward edge of said tray, said basket having at least one wall thereof formed of a perforated mesh material, said connecting means comprising linkage means operative to lift the rearward edge of said tray to a position above said forward edge of said tray during said tilting operation and to position the mesh wall of said basket above the surface of said bath and generally below other portions of said basket.
Claim 4
Dependent Claim
182 words
A cold sterilization unit comprising an open-topped tank adapted to contain a bath of germicidal solution therein, a lid adapted to be moved between closed and open positions relative to the open top of said tank, holder means adapted to be immersed within the bath in said tank for supporting instruments to be sterilized within said germicidal bath, said holder means including a perforated collection receptacle removably attached thereto for immersion into said bath along with said holder means and instruments, and linkage means responsive to movement of said lid from its said closed to its said open position for lifting both said holder and its attached receptacle from said bath and for depositing any instruments supported by said holder means into said collection receptacle at a position above the normal surface level of bath, whereby germicidal solution adhering to said instruments drains into said bath via the perforations in said collection receptacle whereafter said collection receptacle may be detached from said holder means for removal of said instruments from said sterilization unit without manually contacting instruments contained in said collection receptacle.
Claim 5
Dependent Claim
182 words
A cold sterilization unit comprising an open-topped tank adapted to contain a bath of germicidal solution therein, a lid adapted to be moved between closed and open positions relative to the open top of said tank, holder means adapted to be immersed within the bath in said tank for supporting instruments to be sterilized within said germicidal bath, said holder means including a perforated collection receptacle removably attached thereto for immersion into said bath along with said holder means and instruments, and linkage means responsive to movement of said lid from its said closed to its said open position for lifting both said holder and its attached receptacle from said bath and for depositing any instruments supported by said holder means into said collection receptacle at a position above the normal surface level of bath, whereby germicidal solution adhering to said instruments drains into said bath via the perforations in said collection receptacle whereafter said collection receptacle may be detached from said holder means for removal of said instruments from said sterilization unit without manually contacting instruments contained in said collection receptacle.
Claim 6
Dependent Claim
50 words
The unit of claim 3 wherein said holder means comprises a tray having slot-and-channel means on the bottom thereof and a slot oN each of a pair of opposite sides thereof, said linkage means comprising arms extending from said lid and slidably engaging each of said slot-and-channel and slot means.
Claim 7
Dependent Claim
43 words
The unit of claim 4 wherein the one of said arms which engages the slot-and-channel means on the bottom of said tray is curved in configuration, the other two arms which engage the slot means on opposite sides of said tray being telescopic.
