Abstract
A fluid specimen collection cup assembly includes a cup defining a large mouth by which a specimen is introduced to the cup. A cover for the mouth is selectively removable. A needle is disposed in one of the cover and the cup defining a fluid passage from inside the cup assembly to outside the cup assembly.

FI~LD OF TEE I~VE~TIO~
This invention is directed to medical specimen collection bottles and more partlcularly to specimen collection bottles also used to transport the specimen from which samples for testing are subsequently taken.
BA~ un~ OF TEE I~VERTIO~
It is common in the medical field to collect body fluids in containers or bottles having a large mouth. The large mouth facilitates filling the bottle. The bottles are capped with a cover which is selectively removable. A screw type cover is typically employed.
Such CUp8 are commonly used for collecting urine speclmens. The patient will commonly be asked to fill the specimen cup. The cover i8 placed over the cup after it has been filled.
The cover is later removed by a medical technician. A needle is fixed to a syringe and a protective plastic guard removed from the needle to expose a needle tip. The needle tip is dipped into the cup and immersed in the specimen. The syringe plunger is pulled back, drawing a sample of the specimen into the syringe. An evacuated test tube with a sealing rubber top is provided. The tip of the needle is plunged through a rubber seal over an end of an evacuated test tube. The plunger of the syringe is then depressed to fill the test tube with the sample of the urine specimen.
Multiple test tubes of samples from a single specimen can be provided in this fashion. The test tube or tubes are then delivered ~2.--to the test facility. The required tests of the urine specimen, such as urine analysis and a urine culture, are conducted on the samples provided in the test tubes.
It is desired to minimize for health care workers, a~
much as possible, the handling of needles and the potential for exposure to bodily fluids. The risk of being accidentally exposed to potentially fatal viruses transmitted in bodily fluids is in Iarge part a function of the frequency of exposure to such fluids.
The risk associated with exposure is potentially aggravated by the coinciding presence of sharp ob~ects, such as needles, capable of piercing the skin of a person.
SUMMABY OF T~R IRVRRTIO~
A fluid specimen collection cup assembly is disclosed comprising a large mouth cup into which the specimen may be deposited. A cover for the large mouth cup is selectively removable. A needle is disposed in one of the cover and the cup defining a fluid passage from inside the cup assembly to outside the cup assembly.
The inventive specimen collection cup assembly reduces the potential for exposure to both bodily fluids and to needles of health care workers preparing specimens for testing. Additionally, the opportunity for contamination of the specimen itself is also reduced. Further, the number of fluid transfers necessary to provide a specimen for testing is reduced. Also, the proposed cup eliminates the use of syringes in transferring fluid from the cup to test tubes.

~RTATT.Rn DRSCRIPTIO~ OF Tn~ ~n~ b~ _MBODIMERT
A fluid specimen collection cup assembly 10 is substantially like specimen collection CUp8 widely in use today throughout the medical field. A cup 12 has a large mouth 14 at a top end 16 for the introduction of fluid specimens. A cover 18 is used to close the mouth 14. The cup 12 and cover 18 have engaging threads 20 for fixing the cover 18 to the cup 12. In some embodiments, threading the cover 18 tightly against the top end 16 will produce sealing engagement therebetween.
The cup assembly 10 is distinguished from cups already in use by the presence of a needle support 22 approximately 5mm in dia. on a side of the cup 12 and a needle 26 extending therefrom.
The needle 26 i8 retained in the needle support 22 by threading engagement therebetween. The attachment is essentially the same as is widely employed to fix needles to syringes. The needle 26 has a retainer element 28 with four fins 30 extending parallel to the needle 26 and a flange 32 engaging threads 34 in the needle support 22. The needle 26 is preferably of small size, 23 gauge for example, which is sufficiently small to resist unassisted 2 1 62~58 flow of the specimen therethrough. Although the needle 26 and needle support 22 are shown extending in a downward direction from near a bottom 32 of the cup 12, alternative embodiments may have the needle support 22 and needle 26 extending from near the top end 16 of the cup 12 or even from the cover 18. A protective cap 38 is removably positioned over the needle 26. The cap 38 has four grooves 40 for receiving the fins 30 of the needle. The cap 38 can be used to thread the needle 26 into the needle ~upport 22.
Fluid i~ introduced to the cup 12 through the large mouth 14 at the top end 16. When the fluid specimen collection cup assembly 10 is used to hold a urine specimen, the urine can be introduced into the cup 12 either directly by the patient, or through a catheter (not shown). A catheter is typically used to direct urine into the cup 12 when it is particularly important tb provide a specimen uncontaminated by anything outside the bladder from which it is drawn, or when the patient i8 confined to bed.
Fluid from the cup 12 is then introduced to an evacuated, sealed test tube 42, or Vacutainer~, as shown in Figure 2. The fluid is introduced to the test tube 42 by first removing the protective cap 38 from the needle 26 and plunging the needle 26 through a rubber seal 44 over an end of the test tube 42. The vacuum in the test tube 42 draws fluid from the cup 12 through the needle 26 and into the test tube 42. The covered cup may be vented to atmosphere or may have a sufficient volume of air inside to permit the fluid to pass therefrom. Any one of several well known vent means can be integrated into the cup assembly 10 if necessary.
When the cup assembly 10 is pulled away from the test tube 42, the rubber seal 44 tends to close behind the withdrawn needle 26, preventing any fluid from leaking out of the test tube, as well as preventing any contamination of the fluid by things outside the test tube 42.
Once sufficient sample~ have been drawn, the remainin8 specimen in the cup 12 is appropriately disposed of. The needle 26 is then unthreaded from the cup 12, and the cup 12, the cover 18 and the needle 26 are then disposed of.
\
It is readily apparent that there is no need to remove the cover 18 from the cup 12 to draw samples, thereby minimizing any risk of spilling the urine specimen onto oneself. There is also a reduced risk of health care workers handling and testing the specimen of sticking themselves with a needle, particularly a contaminated needle, in that there is no longer a need to withdraw a portion of the specimen with a needle tipped syringe (not shown) to transfer some portion of the specimen into a test tube 42. This is particularly beneficial, as it is often necessary to extract multiple samples from the fluid specimen collection cup assembly 10 to perform at least a urine analysi~ and a urine culture.
While one embodiment of the invention has ben described in detail, it will be apparent to those skilled in the art that the disclosed embodiment may be modified. Therefore, the foregoing description is considered exemplary rather than limiting, and the true scope of the invention is defined in the following claims.
