Abstract
A method and apparatus for collecting and storing urine comprises a collecting funnel and collection tank. The funnel has a valve that opens flow of urine begins and closes once the flow stops based on a flow sensor. The flow time of urine is recorded and used to regulate the evacuation and inert gas filling of a head space in the collection container once the urine is collected. The inert gas protects the urine from oxidation so that degradation is minimized while in the collection container. A similar control can be exercised when a bottle is filled with urine from the collection container, wherein head space in the bottle is filled with inert gas for oxidation protection to form a finished package. The head space of finished package can be evacuated to minimize degradation of the urine once the urine is accessed an initial time in the finished package.

DESCRIPTION OF THE INVENTION
(5) One embodiment of the invention is depicted in
(6) Still referring to
(7) Included with the funnel is a valve 23 and a collection container 25. The valve 23 controls the flow of urine from the stall 22 to the collection container 25. While any valve can be used, a preferred valve is a gate valve. The valve is also one that provides an air tight seal to the collection container 25.
(8) The apparatus 20 also includes a sensor 27, which is designed to sense the beginning and end of the flow of urine into the funnel, preferably a contact sensor that detects contact of urine with the funnel wall 29. This can be any type of sensor that would detect contact with the wall by a material such as urine. These contact sensors are well known in the art so that a further description of them is not needed for understanding of the invention. Of course other sensors may be employed that will detect the flow of urine into the funnel, e.g., ones using light.
(9) The sensor 27 is linked to a controller 31, with the controller 31 designed to control the flow of an inert gas source, designated as 32 in
(10) The collection container 25 and funnel are preferably cooled or chilled to around 60 degrees F. so that the urine when contacting the funnel wall 29 and entering the collection container 25 is chilled. The cooling is shown as coils 35 on the funnel and coils 37 on the collection container, wherein a cooling fluid (not shown) is supplied to the coils 35 and 37 for cooling purposes. Of course, other known ways to chill the funnel and collection container can be employed.
(11) The collection container can also be equipped with a discharge line 39 that is in communication with the bottling apparatus 30 with its use described hereinafter.
(12) The assembly of the collection container, the funnel, the controller, sensor, inert gas supply, and valve are considered means for collecting and storing urine in an oxygen free atmosphere to minimize the degradation of the urine during the collection and storage thereof. The supply of the inert gas is essential for filling the collection container prior to its receipt of urine and then can be optionally employed to provide additional inert gas once the flow of urine ceases and the valve 23 closes.
(13) In the method aspect of the urine collection, the valve 23 is in its closed state and the collection container is filled with an inert gas at a pressure around atmospheric. Once urine begins to fall into the funnel 21 and contact the funnel wall 29, the sensor 27 detects the urine and signals the controller 31 to open the valve 23. Because the inert gas is heavier than air, it occupies the volume of the collection container 25 and the urine passes through the inert gas and towards the bottom of the collection container 25.
(14) Once the sensor 27 determines that no more urine is flowing into the funnel 21, the controller 31 closes the valve 23 and the urine is held in the collection container under cover of the inert gas, thus not in the presence of oxygen.
(15) Once the valve 23 is closed, the controller 31 can, optionally, supply additional inert gas to the collection container to ensure that it only contains inert gas. This is an optional step because once the urine is funneled into the collection container 25; the inert gas therein is displaced out through the valve opening during the filling step. Therefore, the inert gas should still occupy the volume of the collection container 25 remaining after urine is collected therein. The supply of the inert gas to the collection container 25 assures the oxygen free state of the urine while in the collection chamber.
(16) The timer of the controller 31 is used in conjunction with the supply of inert gas after collection of urine and closing of the valve 23. That is, the timer tracks the time that the valve 23 is open and then provides a flow of inert gas from source 32 via opening of the inert gas valve 33 that matches or approximates the time that the valve 23 is open. Of course, the controller 31 could be designed to supply inert gas to the collection container 25 for a period longer than the valve 23 opening time, if so desired, to provide further assurance of an absence of oxygen into the collection chamber.
(17) Once a quantity of urine is collected, it can be sent to the bottling apparatus 30 via the discharge line 39. Prior to sending the collected urine to the bottling apparatus 30, the supply line is purged of any air with inert gas. This assures that the travel of the urine in the oxygen-free state in the collection container 25 does not encounter any oxygen on the way to the bottling apparatus 30. This purging can be done in any conventional way and further details of this step are not deemed necessary for understanding of the invention.
(18) Turning now to
(19) One difference in the bottling apparatus and method of filling is that the apparatus 30 includes a feed line for inert gas and a feed line for urine. This aspect of the apparatus is shown schematically in
(20) In
(21) In
(22) The invention also entails a system to preserve as much as possible the oxygen free state of the urine in the finished package 53. With reference to
(23) In
(24) While a typical vacuum plug or rubber stopper and vacuum pump are preferred, any means that would be able to remove air (evacuate it) in a container holding an amount of urine can be employed in conjunction with the finished package.
