Description

FIELD OF THE INVENTION

The present disclosure relates to an apparatus for collecting, storing and transferring a liquid specimen.

BACKGROUND OF THE INVENTION

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Fluid biological specimens are routinely collected and analyzed for a variety of medical and other purposes. It is commonplace for a patient visiting a medical facility for evaluation and/or treatment to be asked to deposit a urine specimen in a cup and provide that specimen to a medical professional for testing. It is also increasingly common for athletes involved in competitive sports to be required to provide a urine specimen which may be divided into two or more sample vials in order to test those athletes for illegal performance enhancing drugs or practices such as doping. More than one sample of the specimen is typically taken from the cup and preserved in the event that the results of one sample analysis are inconclusive or to provide additional evidence of a particular result. Of course it is not only athletes who may undergo testing via urine analysis wherein the specimens must be protected from contamination starting from collection in a cup throughout transfer and analysis of specimen samples. Thus, it is often necessary to prevent spillage or contamination of liquid specimens throughout any transport of the specimen or transfer thereof to another container(s).

Most currently used specimen cups do not provide apparatus for transferring of a liquid specimen to a vial or other container for laboratory testing of the specimen.

Accordingly, it is an object of the present disclosure to provide an apparatus for collecting, storing and transferring a liquid specimen that improves over prior art devices.

FIGS. 1-6 illustrate example embodiments of a specimen collection, storage and transfer apparatus 10 according to the present invention. A specimen cup 12 provides a receptacle into which a liquid specimen, for example urine, is deposited through an opening 14 in the top of the specimen cup. As well known in the art, the specimen cup 12 defines a threaded portion 15 surrounding the opening 14 for engaging a lid 16 having a complementary threaded portion 17. The apparatus 10 includes the lid 16 for sealing the opening 14 and retaining a liquid specimen in the specimen cup 12. In the illustrated embodiment, the lid 16 includes a concave center portion 18 extending substantially across a diameter of the lid for covering the entirety of the opening 14 of the specimen cup 12. A collar 20 is formed integral with the center portion 18 and protrudes outwardly from a bottom side 19 of the center portion 18. An aperture 22 extends through the lid 16 and the collar 20. The center portion 18 is generally smooth surrounding the aperture 22 for receiving a seal thereon. In one embodiment, the aperture 22 is approximately 3.175 millimeters (3.175 mm) in diameter, D. In other embodiments, depending on the size of the specimen cup 12 and the application, a diameter of the aperture 22 may be in a range between about two millimeters (2 mm) to about one centimeter (1 cm). The aperture 22 is defined collectively by the center portion 18 and the collar 20. In the illustrated embodiments, the lid 16 and collar 20 is formed of plastic. However, in other embodiments the lid may be formed of other types of materials.

As shown in FIG. 2, the collar 20 extends below the center portion 18 of the lid a length L which averages about 5 mm. Due to the concave shape of the center portion 18, the length L of the collar 20 extending below the center portion is not uniform about a circumference of the collar. In other embodiments, the length L of the collar extending below the center portion 18 of the lid may be in a range of about 3 millimeters to about 2 centimeters or more depending on the size of the container and/or a tube 26 of the transfer assembly 50 (described further hereinbelow). The collar 20 being configured to support the tube 26 of the transfer assembly in an upright position as shown in FIG. 2.

Referring to FIG. 6, in one embodiment, the apparatus 10 further includes a seal 24 for removably covering and providing an airtight and leak proof seal over the aperture 22. The aperture 22 may be sealed with an adhesive seal 24 covering the aperture. In one embodiment, the seal 24 is formed of a circular shaped plastic material having a reusable adhesive disposed on one side thereof for removable attachment to an upper surface 23 of the center portion 18 of lid 16 surrounding the aperture 22. As shown in FIG. 1, the surface 23 is smooth in part for receiving the seal 24 and facilitating a secure coupling therewith for retaining a liquid specimen in the specimen cup 12 even in the event the specimen cup 12 is tipped over or shaken while a liquid specimen is stored therein.

In one embodiment, the aperture 22 has a diameter D of approximately 3.175 (3.175 mm) and the seal 24 is formed of a plastic material in the shape of a circle generally and having a diameter of about 25.4 millimeters (25.4 mm). Thus in one embodiment the area of the seal 24 with a reusable adhesive on one side thereof, is about sixty-five (65) times the area of the aperture 22 to be closed via the seal 24. In other embodiments, a ratio of the area of the seal 24 relative to the area of the aperture 22 may be less and in a range between about 24 to about 65 or more. In other embodiments a single use seal may be used wherein an area of the seal may be only slightly larger than the area of the aperture 22 for closing the aperture in a leak proof manner.

In the illustrated embodiment, the seal 24 defines a protrusion 24A extending outwardly from a circumference of the seal for grasping the seal and facilitating removal and/or installation or otherwise handling of the seal. In the illustrated embodiment the protrusion 24A is made of the same material as the seal and formed integral therewith. In one embodiment, the protrusion 24A extends outwardly from the circumference of the seal 24 approximately 3 mm and defines a generally rectangular or trapezoidal shaped tab having a width of about 2-3 mm. In one embodiment the protrusion 24A includes an adhesive on one side thereof the same as the remainder of the seal 24. Alternatively, in other embodiments, the protrusion 24A does not have an adhesive disposed on either side thereof so the protrusion 24A does not adhere to the lid 16 which may better facilitate grasping and removing the seal 24 from lid 16.

Referring to FIG. 1, the apparatus 10 includes a transfer assembly 50 including the lid 16, a tube 26 and a second cup 28 attached to the tube. The tube 26 defines a first end 29 and an opposing second end 31. The second end 31 can be inserted through the aperture 22 located in the lid 16 such that the second end of tube 26 may be submerged in a liquid specimen contained in the specimen cup 12 when the lid is coupled to the specimen cup. The tube 26 is supported in an upright position relative to the specimen cup 12 by contact with the collar 20. In the illustrated embodiment, the tube 26 fits snugly within the aperture 22 so that there is a leak proof seal formed between the tube 26 and lid 16 and so that the tube 26 is positioned generally perpendicular to the opening 14 in the specimen cup 12 when the tube is coupled to the lid 16 and the lid is attached to the specimen cup. This snug fit arrangement between the lid 16 and the tube 26 provides a coupling between the tube 26 and the lid 16 so that transfer assembly 50 stays together as one unit which can be picked up and handled without the tube 26 falling apart from the lid 16. Additionally, in one embodiment, the second cup 28 (described following) is also attached to the tube 26 so that the entire transfer assembly 50 is provided as an assembly of coupled together parts. However, it is not necessary that an outer wall of the tube 26 form an air tight or leak proof seal with the aperture 22 within the collar 20. Thus, in other embodiments the tube 26 can be loose fit within the collar 20 and still maintain the second cup 28 in a generally upright position.

In one embodiment, the tube 26 defines a length sufficient so that the second end 31 of the tube may be positioned within the aperture 22 such that the second end 31 of the tube extends all the way to the interior bottom of the specimen cup 12 for allowing transfer of substantially the entire contents from the specimen cup 12 via the tube 26. In the FIG. 1 embodiment the second end 31 of tube 26 is flat and generally perpendicular to a length of the tube.

Referring to FIG. 4, in another embodiment, the second end 31 of tube 26 is angular and defines an angle alpha relative to the long axis 37 of the tube, the angle alpha being in a range between about 90 degrees and about 45 degrees and configured to prevent blockage of the second end 31 of the tube 26 by the flat bottom 27 of specimen cup 12.

Referring again to FIG. 2, a first end 29 of the tube 26 passes through and is affixed to the bottom 34 of a cup 28. As shown in FIG. 2, the cup 28 includes a nipple 41 extending outwardly from the bottom of the cup. In the FIG. 2 embodiment, the nipple is formed integral with the cup 28. The nipple 41 defines a hole through the nipple and the bottom 34 of the cup 28 for receiving the tube 26 therethrough. The first end 29 of the tube is inserted into the hole in nipple 41 and sealably fixed thereto. In the FIG. 2 embodiment, a needle 36 protrudes from the first end 29 of tube 26 and is affixed thereto. The needle 36 is configured to pierce a seal of an evacuated vial (not shown) for transferring a liquid specimen contained in the specimen cup 12 through the tube 26 and into the vial. In another embodiment (not shown) the first end 29 of tube 26 may extend through the nipple 41 and define a pointed end that extends into the interior of cup 28 for engagement with a vial. Thus the needle 36 may be omitted in some embodiments of the apparatus 10. The needle 36 extends into the cup 28 such that potential spillage of a specimen from the first end 29 of tube 26 disposed therein is contained within the cup. A tip 38 of the needle 36 is disposed within the cup 28 thereby to prevent spillage of specimen outside the cup 28 and potential injury to or contamination of a user, such as a lab technician, from puncture by the needle 36. By preventing a technician from contacting the needle 36, the disposition of the needle 36 inside the cup 28 also prevents a technician from contaminating the specimen.

The cup 28 defines an open top 40 for receiving a vial therein. Thus, an inside diameter of cup 28 is configured for receiving a vial therein for inserting the vial in cup 28 and transferring the specimen to the vial as will be disclosed further hereinafter. Depending on the size of the specimen cup 12 and the size of a vial (not shown) intended to be used with the apparatus 10, the diameter of the cup 28 may be sized accordingly. Thus, the diameter of the cup 28 should be at least slightly larger than the diameter of the vial. As mentioned above, a height of the cup 28 should be at least longer than a length of the needle 36 extending into the cup.

FIG. 7 illustrates an embodiment of a specimen transfer assembly 50 according to the present invention. The transfer assembly 50 includes a lid 16, tube 26 inserted through the aperture 22 in the lid and the transfer cup 28 attached to the first end of the tube 26 as described above. The transfer assembly 50 is configured for use with commercially available specimen cups and can be coupled thereto via the threads 17 defined by the lid 16.

In use of apparatus 10, the specimen cup 12 may be provided to a patient for depositing a liquid specimen such as urine in the specimen cup 12 via opening 14. The lid 16 may be placed on the specimen cup 12 via the threads 15, 17 for attaching the lid to the specimen cup and sealing the opening 14 thereof. The seal 24 may be attached to the center portion 18 of the lid 16 and used to seal the aperture 22 in the lid for transporting and/or storage of the specimen within the specimen cup 12.

Thereafter, to transfer the specimen from the specimen cup 12 to an evacuated vial (not shown), the seal 24 must be removed from covering the aperture 22 in the lid. The transfer assembly 50 is then coupled to the lid 16 by inserting the second end 31 of tube 26 through the aperture 22 and into the specimen cup via the opening 14 therein. The second end 31 of the tube 26 being pushed through the lid 16 so the end thereof extends at least into and is covered by a liquid specimen (not shown) contained within the specimen cup 12. The transfer assembly 50 being positioned as shown in FIG. 1 so that the tube 26 extends outwardly from the specimen cup 12 in an upright position and generally perpendicular with the opening 14 of the specimen cup 12. The cup 28 also being generally in an upright position so that the opening 40 thereof is disposed substantially parallel to the opening 14 of specimen cup 12. A vial (not shown) to which the specimen is to be transferred may typically be covered at the top with a penetrable seal.

To carry out the transfer, a vial as described above (not shown) is placed top down into the opening 40 of cup 28 of the transfer assembly 50. A technician pushes the evacuated vial downwards against the needle 36 until the tip 38 of the needle 36 penetrates the seal of the evacuated vial forming a continuous channel between the evacuated vial and the second end 31 of the tube 26 submerged in the specimen. Once a sealed channel is formed, a sample of the specimen from the specimen cup 12 is transferred to the sample vial by suction. After a volume of the sample is transferred to the sample vial, the vial may be removed from the apparatus 10 by the technician by pulling the vial away from the needle 36 and out of the cup 28. This procedure may be repeated as needed to obtain additional samples.

Once transfer of one or more samples is complete, the tube 26 attached to the cup 28 may be removed from the collar 20 of the lid 16 by application of minimal force by the technician. In one embodiment, any spillage of the specimen which may occur as the result of removal of the tube 26 from the specimen cup 12 is contained within the concave center portion 18 of the lid 16 and is thereby controlled preventing contamination of the laboratory space and the technician. Any spillage thus contained may be cleaned by procedures well known in the art.

In the embodiment shown in FIG. 2, the aperture 22 is displaced from the center of the center portion 18 of the lid 16 thereby minimizing the possibility that potentially contaminated spillage of the specimen collected on the concave surface 18 of the lid 16 will fall back into the specimen cup 12 through the open aperture 22. In one embodiment, the specimen cup 12 may be sealed by placing the seal 24 over the aperture 22. The tube 26 and cup 28 of transfer assembly 50 may then be disposed of properly by means well known in the art. The specimen remaining in the sealed specimen cup 12 may be stored for potential future use without the need for further manipulation or may be disposed of safely without spillage.

Example embodiments thus being described, it will be appreciated by one skilled in the art that example embodiments may be varied through routine experimentation and without further inventive activity. Variations are not to be regarded as a departure from the spirit and scope of the exemplary embodiments, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
