Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
A cassette for pathological tissue examination consisting of a container proper and a lid, the lid being engagable with and detachable from the container proper, the container proper and the lid are made of a chemical-resistant synthetic resin, partition means associated with at least one of said container proper and said lid so that when said container proper and said lid are engaged the interior surface of the container proper, the interior surface of the lid and said partition means define a plurality of cylindrical sample chambers which are independent and separated from one another, the interior surface of the container proper defining each of said chambers having a plurality of small through-holes, the interior surface of the lid defining each of said chambers having a plurality of small through-holes, and a surface of at least one of said container proper and said lid having means for recording information for identifying pathological tissue.

Claim 7
Dependent Claim
236 words
A cassette for the pathological examination of a multiplicity of separate tissue samples consisting essentially of main container body means and lid means engagable therewith, both of which are made of chemical resistant synthetic resin, said main container body means having an upper surface, hinge means connecting said upper surface to said lid means in a movable manner, when said main container body means and said lid means are not engaged, said hinge means maintains said upper surface substantially coplanar with said lid means, said upper surface having chamber means defining a plurality of independent, individual, separate, substantially cylindrical, sample chambers therein, wherein each of said sample chambers has a lower surface containing a plurality of small through-holes therein, said lid means having a plurality of circular, projected rims equal in number to said sample chambers and dimensioned and positioned so as to engage said sample chambers in a sealable manner when said main container body means and said lid means are engaged, the area of said lid means encompassed by each of said circular rims having a plurality of small through-holes so as to provide flow communication between each of said sample chambers and said lid means, and a surface of at least one of said main container body means and said lid means, proximate to each of said sample chambers, having means for recording information related to the samples in each of said chambers.
Claim 8
Dependent Claim
236 words
A cassette for the pathological examination of a multiplicity of separate tissue samples consisting essentially of main container body means and lid means engagable therewith, both of which are made of chemical resistant synthetic resin, said main container body means having an upper surface, hinge means connecting said upper surface to said lid means in a movable manner, when said main container body means and said lid means are not engaged, said hinge means maintains said upper surface substantially coplanar with said lid means, said upper surface having chamber means defining a plurality of independent, individual, separate, substantially cylindrical, sample chambers therein, wherein each of said sample chambers has a lower surface containing a plurality of small through-holes therein, said lid means having a plurality of circular, projected rims equal in number to said sample chambers and dimensioned and positioned so as to engage said sample chambers in a sealable manner when said main container body means and said lid means are engaged, the area of said lid means encompassed by each of said circular rims having a plurality of small through-holes so as to provide flow communication between each of said sample chambers and said lid means, and a surface of at least one of said main container body means and said lid means, proximate to each of said sample chambers, having means for recording information related to the samples in each of said chambers.
Claim 9
Dependent Claim
