Abstract
Abstract A device for obtaining cervical specimens directly as smears on microscope slides for cytologic evaluation. An identification slide is mounted in one end of a slide carrier that is slidably journaled in a tubular insertion housing, and the slide is arranged to be removed from the slide carrier after a smear has been obtained by rotation of the slide carrier and slide with respect to the insertion housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A cervical tissue cell specimen gathering device comprising an elongate, tubular insertion housing having an open insertion end and a rear end with a hole therethrough; a slide carrier including a shaft extending slidably and rotatably from a handle larger than said hole in the rear end, through said hole and into said housing, a collar on the shaft within the housing limiting travel of the shaft through the rear end in the direction of the handle, and a support frame for a slide at the end of the shaft opposite to the handle, said support frame being entirely within the housing when the collar is in engagement with the rear end of the housing, and projecting at least partially from the housing when the handle is in engagement with the rear end of the housing; and a microscope slide having a collection surface thereon, said slide being removably secured to the support frame, whereby said collection surface on the slide is outside the housing when the handle is in engagement with the rear end of the housing.
Claim 2
Dependent Claim
178 words
A cervical tissue cell specimen gathering device comprising an elongate, tubular insertion housing having an open insertion end and a rear end with a hole therethrough; a slide carrier including a shaft extending slidably and rotatably from a handle larger than said hole in the rear end, through said hole and into said housing, a collar on the shaft within the housing limiting travel of the shaft through the rear end in the direction of the handle, and a support frame for a slide at the end of the shaft opposite to the handle, said support frame being entirely within the housing when the collar is in engagement with the rear end of the housing, and projecting at least partially from the housing when the handle is in engagement with the rear end of the housing; and a microscope slide having a collection surface thereon, said slide being removably secured to the support frame, whereby said collection surface on the slide is outside the housing when the handle is in engagement with the rear end of the housing.
Claim 3
Dependent Claim
37 words
A cervical tissue cell specimen gathering device as in claim 1, wherein the slide has a cell gathering section formed of smooth material and a data receiving section formed of material adapted to receive character data thereon.
Claim 4
Dependent Claim
34 words
A cervical tissue cell specimen gathering device as in claim 2, wherein the data receiving section is within the housing when the handle is in engagement with the rear end of the insertion tube.
Claim 5
Dependent Claim
43 words
A cervical tissue cell specimen gathering device as in claiM 3, wherein the support frame is flexible and includes means whereby the microscope slide is snapped into the support frame and is adapted to be released therefrom during bending of said support frame.
Claim 6
Dependent Claim
22 words
A cervical tissue cell specimen gathering device as in claim 4, further including a positioning shield radiating from the insertion tube housing.
Claim 7
Dependent Claim
27 words
A cervical tissue cell specimen gathering device as in claim 4, wherein the support frame is formed as one piece with the shaft of the slide carrier.
Claim 8
Dependent Claim
43 words
A cervical tissue cell specimen gathering device as in claim 1, wherein the support frame is flexible and includes means whereby the microscope slide is snapped into the support frame and is adapted to be released therefrom during bending of said support frame.
