Problems solved by technology

Moreover, the frequent dumping of urine samples from one container to another in medical facilities and laboratories, with corresponding opening and sealing of containers creates the potential for contamination among medical facilities and laboratory personnel
In addition, there is a possibility of container leakage during transportation
This leakage also has the potential to contaminate the specimen, other nearby specimens, or personnel who must remove improperly sealed containers in the laboratory

Embodiment Construction

[0016] Such as figure 1 As shown in FIG. 2 and FIG. 2 , assembly 10 includes tube 12 and cover 14 . Tube 12 is integrally molded from thermoplastic material and includes an open top end 16 and a closed bottom end 18 . A generally cylindrical side boundary 20 extends from the open top end 16 to a location 22 between the open top end 16 and the closed bottom end 18 and defines an outer diameter "a".

[0017] Tube 12 also includes a generally conical base 24 extending from base end location 22 of cylindrical side boundary 20 to base end 18 of tube 12 . More particularly, conical base 24 has an apex that is integral with cylindrical side surface 20 at location 22 and thus defines a substantially identical diameter. The conical base 24 tapers to a smaller cross-sectional dimension further from the cylindrical side boundary 20 and terminates at a small diameter spherical base wall 26 .

[0018] Tube 12 also includes a fin 28 extending integrally outwardly from conical base 24 . ...

Abstract

A urine sample container assembly is provided. The assembly includes a vacuum tube and a cap for maintaining a vacuum condition in the tube and sealing the tube after a urine sample is placed therein. The tube includes an open top end engaging the shroud and a cylindrical interface extending from the open top end. A conical base extends from the lower end of the cylindrical interface to the bottom end of the tube. The fin extends outwardly from the conical base and defines a profile substantially the same as that of the round bottom tube. In this way, the tube can be used in chemical analyzers constructed for round-bottomed tubes and in centrifuges so that the sediment is retained in the conical bottom.

Description

technical field [0001] The present invention relates to a tube, in particular a urine sample tube, which can efficiently collect a sample and can be used with any of the different types of laboratory testing devices. Background technique [0002] Urine samples are usually collected by the patient in an open container and then transferred into the container by a nurse or medical professional. The container is then sealed and shipped to a laboratory for analysis. A lab technician will open the container and pour some of the urine into several other containers for analysis. For example, a portion of the urine sample is poured into a tube with a conical bottom arranged for use in a centrifuge. The tubes are sealed and centrifuged so that cells, exfoliation or crystals collect at the conical bottom of the tube as a pellet. The liquid portion of the sample is decanted and the precipitate remaining in the conical portion of the tube is transferred to a microscope slide for furth...
