Urinanalysis vial

Claim 2

A vial for liquid specimens including, in combination: (a) an elongated elastic bellows having a closed bottom and top neck of generally cylindrical configuration, said bellows being biased to an extended position defining a given volume and capable of being manually collapsed; and (b) a straw axially positioned in said bellows, an upper portion of said straw being circumferentially frictionally engaged by said neck, said straw being substantially contained within said bellows when said bellows is in the extended position, whereby said bellows is axially guided by said straw when said bellows is collapsed with said straw thereupon being frictionally urged through said neck such that the upper end of said straw projects substantially from said bellows, said straw further functioning as a passage for transferring a liquid specimen by suction into said bellows upon manual release of the bellows.

Claim 3

A vial according to claim 1, in which said straw is disposed of after a specimen has been transferred into said bellows; and a cap receivable over said neck and defining a fixed volume for collection of liquid and sediment.

Claim 4

A vial according to claim 2, in which said bottom is shaped to be held in a centrifuge.

Claim 5

A urinanalysis vial for collecting, centrifuging and dispensing urine specimens incidental to laboratory analysis, including, in combination: (a) an elongated plastic tube having a corrugated wall normally biased to an expanded position defining a given initial volume and capable of being axially collapsed in the manner of a bellows, one end of said tube defining a bottom shaped to be received and held in a centrifuge machine and the other end of said tube defining a top terminating in a cylindrical collar coaxial with the corrugated wall; (b) a straw received axially in said tube having an outside diameter substantially equal to the inside diameter of said cylindrical collar so that the upper end of said straw is frictionally held in said collar, the remaining portion of the straw passing axially down the tube, the corrugations of the wall defining minimum internal diameters being related to the diameter of the straw such that when the corrugated wall is collapsed in the manner of a bellows, the exterior wall of the straw will function to hold the corrugations in substantial rectilinear axial alignment; and (c) a cap having an interior hollow portion defined by a initial cylindrical entrance for fitting over said collar so that the cap is supported on the top of the tube, said hollow portion communicating with said cylindrical entrance and extending up into said cap to define a fixed volume for the collection of sediment and a given amount of fluid upon centrifuging of a liquid specimen in said tube, whereby said cap can be removed and said tube can be manually axially collapsed to cause said straw to be urged frictionally through the collar by the bottom of the tube engaging the straw during the collapsing of the corrugated wall, the extending end of the tube serving as a conduit for sucking a urine specimen into said tube upon manual releasing of the pressure holding the tube in its collapsed state, the tube being filled with a known given volume of specime after the corrugated walls reach their normal expanded position, said straw then being pulled from the collar and disposed of and said cap replaced on the collar, the tube then being in condition for transfer to a centrifuge machine, the liquid specimen being maintained in its sterile condition, said cap again being removable after centrifuging to provide a fixed volume of liquid and sediment for intermixing and dispensing onto an examination slide.

Claim 6

A urinanalysis vial for collecting, centrifuging and dispensing urine specimens incidental to laboratory analysis, including, in combination: (a) an elongated plastic tube having a corrugated wall normally biased to an expanded position defining a given initial volume and capable of being axially collapsed in the manner of a bellows, one end of said tube defining a bottom shaped to be received and held in a centrifuge machine and the other end of said tube defining a top terminating in a cylindrical collar coaxial with the corrugated wall; (b) a straw received axially in said tube having an outside diameter substantially equal to the inside diameter of said cylindrical collar so that the upper end of said straw is frictionally held in said collar, the remaining portion of the straw passing axially down the tube, the corrugations of the wall defining minimum internal diameters being related to the diameter of the straw such that when the corrugated wall is collapsed in the manner of a bellows, the exterior wall of the straw will function to hold the corrugations in substantial rectilinear axial alignment; and (c) a cap having an interior hollow portion defined by a initial cylindrical entrance for fitting over said collar so that the cap is supported on the top of the tube, said hollow portion communicating with said cylindrical entrance and extending up into said cap to define a fixed volume for the collection of sediment and a given amount of fluid upon centrifuging of a liquid specimen in said tube, whereby said cap can be removed and said tube can be manually axially collapsed to cause said straw to be urged frictionally through the collar by the bottom of the tube engaging the straw during the collapsing of the corrugated wall, the extending end of the tube serving as a conduit for sucking a urine specimen into said tube upon manual releasing of the pressure holding the tube in its collapsed state, the tube being filled with a known given volume of specime after the corrugated walls reach their normal expanded position, said straw then being pulled from the collar and disposed of and said cap replaced on the collar, the tube then being in condition for transfer to a centrifuge machine, the liquid specimen being maintained in its sterile condition, said cap again being removable after centrifuging to provide a fixed volume of liquid and sediment for intermixing and dispensing onto an examination slide.

Claim 7

A vial according to claim 4, in which said cap is of a transparent material so that said specimen can be visually examined prior to removal from said cap.

Claim 8

A vial according to claim 4, in which said cap is of a pliable plastic material so that it can be manually squeezed to facilitate dispensing of said specimen.

Claim 9

A vial according to claim 4, including flexible tie means for preventing complete separation of said cap from said tube after removal from the top until an intentional pulling force is applied to the cap to separate the same.

Claim 10

A vial for liquid specimens, comprising: an elongated elastic bellows having a closed bottom and a top defining a generally cylindrical neck, said bellows being normally biased to an extended position and being manually collapsible to a compressed position; and a straw generally coaxially positioned within said bellows with said straw substantially contained within said bellows and with an upper portion of said straw frictionally engaged within said neck when said bellows is in the extended position; said closed bottom of said bellow pushing said straw partially through said neck upon manual collapse of said bellows whereupon said neck frictionally engages a lower portion of said straw and said straw projects a substantial distance from said bellows; said bellows being releasable subsequent to collapse to draw a liquid specimen through said straw into the interior of said bellows.

Claim 11

A vial for liquid specimens, comprising: an elongated elastic bellows having a closed bottom and a top defining a generally cylindrical neck, said bellows being normally biased to an extended position and being manually collapsible to a compressed position; and a straw generally coaxially positioned within said bellows with said straw substantially contained within said bellows and with an upper portion of said straw frictionally engaged within said neck when said bellows is in the extended position; said closed bottom of said bellow pushing said straw partially through said neck upon manual collapse of said bellows whereupon said neck frictionally engages a lower portion of said straw and said straw projects a substantial distance from said bellows; said bellows being releasable subsequent to collapse to draw a liquid specimen through said straw into the interior of said bellows.
