The present invention relates generally to the field of medical analysis devices, and more particularly to the field of body fluid collection devices, and still more particularly to body fluid collecting, storage, transporting, and dispensing systems, for blood, saliva, sperm, pus, and even more particularly to a system enabling streaking, or wiping, a sample onto an agar plate or the like.
Urine analysis is one of, if not the, most common medical lab analysis procedures. The present inventor understands that many millions of such urine analysis procedures are performed each week in the United States alone.
Such urine analysis procedures typically involve having a patient urinate into a hand held cup-like receptacle and then sending (that is, transporting) the entire urine-containing receptacle to an appropriate laboratory for analysis, even though only a small amount of the contained urine is required for analysis. The end result is that for any particular laboratory, a relatively large number of such urine collecting receptacles, representing a large volume of space and often requiring being kept cool, must be transported to the laboratory, even though only a small percentage (10-15 ml) of each urine sample is needed for the analysis. Moreover, the handling of the cumulative large quantity of urine contained in the many receptacles can present health risks to health care personnel, because of the possibility of hepatitis virus, AIDS virus, chlamydiaT, and other pathogens being present in the urine samples, and the possibility of urine spillage. Which can soil the users hand.
In addition, abusive drug testing of individuals for employment purposes and civil or criminal matters is widely performed, and improvements to the collecting and testing of urine samples and the collecting and transporting of back-up urine samples are needed. This applies to other on-site testing such as IVD analytical testing for UTI, diabetes, pregnancy, ovulation, HIV among others.
It is thus an objective of the present invention to provide a urine (or other bodily fluid) containing, transporting, and dispensing system that overcomes the above-mentioned problems heretofore encountered in existing urine collection and transporting procedures.
Another objective is to provide for safe collection transport and dispensing of a body fluid onto an agar plate, or the like, by smearing or streaking.
Prior art devices for this purpose have included dip sticks for transferring a sample onto a plate for examination and analysis. Thos procedure is not secure, meaning that accidental touching or contamination of the sample can easily occur.
A body fluid collecting, transporting, and dispensing system in accordance with the present invention generally includes a body fluid collecting receptacle and, in combination therewith, an ergonomic handle for supporting the receptacle in a fluid collection position. The handle includes a fluid collecting and storage sample chamber which is in fluid communication with the receptacle to receive a sample of the body fluid.
Because the handle is removable from the receptacle, it provides for safe transport and dispensing of the body fluid sample. In other words, the original collecting receptacle can be sealed and disposed while a fluid sample is securely kept and sealed and then separately transported and dispensed at a receiving area (lab).
More particularly, in accordance with the present invention, the handle may include a sample withdrawing plunger with a head disposed in the chamber and a tip for withdrawing a fluid sample through a fitting in the receptacle. Preferably, the plunger is removable from the head and handle and the system further comprises a tip cap to facilitate safe transport of the handle containing the fluid sample. Multiple reusable plungers may be provided and used at all receiving area or labs.
In one embodiment, the present invention the fluid sample chamber includes a rotatable stopper at an end opposite of the tip and the fluid chamber includes an air vent aperture.
This aperture is disposed at a position exposable by rotation of the stopper in order to enable dispensing of the fluid sample through the tip with the cap removed.
In one embodiment, a flexible hollow streaker is provided and attachable to the tip for enabling streaking, or swiping, of fluid sample from the chamber onto an agar plate or the like.
In order to improve efficiency of fluid collection, the receptacle may include a displacement member which is fixed within the receptacle and disposed at a position which raises a fluid sample level within the receptacle up to the fitting.
In this manner, when a patient can only excrete a small quantity of fluid sample it still can be effectively collected by the receptacle while at the same time providing a sufficient size fluid sample to the collection handle.
This feature is available for all of the embodiments in accordance with the present invention which includes several handle configurations.
For example, in another embodiment of the present invention, the handle includes a squeezable bulb disposed at an end of the chamber to withdraw the fluid into the chamber.
A sealable and unsealable port in the chamber may be provided at a spaced apart distance from the tip with unsealing of the port enabling dispensing of the fluid sample through the tip. This port operates in a manner similar to the air vent aperture hereinabove described.
In one sub-embodiment, a separable tape member is provided for sealing the port and in another sub-embodiment, a stretchable elastic member is provided for sealing the port along with a mechanism for stretching the elastic member to open the port, when desired, for dispensing of the fluid sample.
The fluid sample chamber may include a tip for withdrawing the fluid sample as hereinabove noted through a fitting in the receptacle and further may include a moveable center tube for introducing the fluid sample into the chamber through an end thereof disposed at a spaced apart distance from the tip.
This end is disposed below the squeezable bar bulb and provides venting for the fluid sample drawn into the chamber.
In that regard, a colored float may be disposed in the chamber for indicating a level of fluid sample in the chamber, thus providing an elderly user an indication of a sufficient sample being collected.
In this embodiment, a cap is provided for sealing the tip and for moving the center to and from the first position to the second position. In order for this function to occur, the cap includes structure including the two opposing cavities of different depths. A first cavity enables sealing of the tip without engagement of the center tube and thus no displacement thereof. The second cavity enables sealing of the tip with engagement and movement of the center tube to the second position.
With the center tube moved to the second position, an egress opening is unsealed thereby enabling later discharge of the sample fluid through the tip.
Further, in accordance with the present invention the bulb may be removable from the chamber and a closable lid may be provided to cover a top of the chamber. The lid may include a puncturable portion, which enables removal of the fluid sample by a syringe or needle by a specialized IVD analytical machine.
All of the embodiments of the present invention provide for the collection, storage, transportation, and dispensing of samples, such as urine, sperm, saliva, blood with absolutely no human contact therewith. Further, the possibility of human contact is eliminated in accordance with the present invention and therefor provides a closed or self-containing system for safe and hygienic fluid sample procedures.
The present invention may further provide advantage by including a solid active reagent disposed in the chamber for dissolution by the fluid sample or a liquid active reagent disposed in a chamber for mixing with the fluid sample. Any number of active reagents may be utilized for conventional pre-treatment of fluid body samples.
In another embodiment of the present invention, a prevacuated tube and holder, which acts as a handle, is provided for drawing the sample from the receptacle.
In yet another embodiment of the present invention, the fluid sample chamber may initially include a vacuum for drawing the sample from the receptacle and a plunger head may be disposed in a chamber with a removable top chamber seal along with a plunger attachment of the head for dispensing of the fluid sample from the chamber through a tip.
A still further embodiment of the present invention provides for a wick to introduce fluid samples into the chamber by lateral flow mechanism. This embodiment is particularly suited for enabling the use of reagent strips which are visible through a chamber window for indicating the presence of at least one component of the fluid sample. In this manner, a prescreening of the sample may be provided by the present invention.
With the use of a rectangular chamber, a plurality of reagent strips may be disposed against each rectangular phase for indicating the presence of a plurality of specific components of the fluid sample. For example, if three reagent strips are utilized on the each rectangular face, a total of twelve preliminary tests may be utilized in accordance with the present invention. Alternatively, the reagent strips may be wetted by flooding or dipping.
In yet another embodiment of the present invention, the receptacle may include at least one reagent strip disposed at the bottom thereof which is visible therethrough for performing the preliminary tests. In addition, this embodiment facilitates the use of a conventional copier machine for recording the results of the preliminary tests provided by the test strips.
