Abstract
Abstract A culture collecting swabbing tip is carried on one end portion of a small diameter flexible wire which enables the tip to reach into a curved and narrow body passage. A sleeve-type handle is telescoped slidably onto the other end portion of the wire and enables the effective length of the wire to be adjusted so that the wire can fit into an outer transport tube but can be effectively lengthened to reach into a long body passage. The transport tube contains a glass ampoule which may be broken to moisten the swabbing tip with a culture-sustaining transport media after a culture has been collected on the tip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A culture collecting and transporting unit comprising a tube made of self-sustaining but flexible material, said tube having an open outer end and a closed inner end, a transport media located within said tube, a cap telescoped removably with the open end portion of said tube and adapted to close said tube, and a culture collecting device located within said tube, said unit being characterized in that said culture collecting device comprises an elongated flexible wire, a swabbing tip on the inner end portion of said wire and located adjacent said transport media, and a sleeve telescoped slidably over the outer end portion of said wire and telescoped slidably into said cap, said sleeve being of such length that the inner end portion of said sleeve projects inwardly from the inner end of said cap and into the outer end portion of said tube when said cap is telescoped to a fully closed position on said tube.
Claim 2
Dependent Claim
157 words
A culture collecting and transporting unit comprising a tube made of self-sustaining but flexible material, said tube having an open outer end and a closed inner end, a transport media located within said tube, a cap telescoped removably with the open end portion of said tube and adapted to close said tube, and a culture collecting device located within said tube, said unit being characterized in that said culture collecting device comprises an elongated flexible wire, a swabbing tip on the inner end portion of said wire and located adjacent said transport media, and a sleeve telescoped slidably over the outer end portion of said wire and telescoped slidably into said cap, said sleeve being of such length that the inner end portion of said sleeve projects inwardly from the inner end of said cap and into the outer end portion of said tube when said cap is telescoped to a fully closed position on said tube.
Claim 3
Dependent Claim
36 words
A culture collecting and transporting unit as defined in claim 1 in which the outer end of said sleeve is closed, the outer end of said wire normally abutting the closed outer end of said sleeve.
Claim 4
Dependent Claim
41 words
A culture collecting and transporting unit as defined in claim 2 further including a bend formed in the outer end portion of said wire and frictionally engaging the inside of said sleeve to restrict sliding of said sleeve along said wire.
Claim 5
Dependent Claim
45 words
A culture collecting and transporting unit as defined in claim 1 in which said sleeve is telescoped snugly over said wire and into said cap whereby said sleeve and said wire are pulled outwardly of said tube when said cap is removed from said tube.
Claim 6
Dependent Claim
126 words
A method of using the culture collecting and transporting unit defined in claim 4, said method comprising the steps of, manually grasping said tube and said cap and pulling said cap away from said tube, grasping said sleeve and said cap and pulling said cap off of said sleeve, pinching said tube into grasping engagement with said wire while pulling on said sleeve to slide said sleeve outwardly along said wire, removing said device from said tube, collecting a culture on said swabbing tip and replacing said device in said tube all while holding said sleeve, pinching said tube into grasping engagement with said wire while pulling on said sleeve and sliding said sleeve outwardly off of said wire, and replacing said cap on said tube.
