Abstract
A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(12) As shown in the attached drawing figures, a collector-analyzer apparatus includes an interface portion 110 (FIGS. 1 and 2) and a receiver portion 120 (FIGS. 5 and 6). These two portions are joined by a flexible interconnection tube 20 so that they may be conveniently set some distance apart during operation.
(13) As shown in FIGS. 1 and 2 interface portion 110 is adapted for joining with the urethra, either male or female, and as such, enables reception of discharged urine; see the arrow labeled “fluid” in FIG. 2. These figures illustrate penis 5 which is inserted into proximal open end 12 of urine tube 10. Tube 10 may be of a transparent soft elastomeric material such as a silicone gel. Internal ribs 16 within tube 10 are shown and it is pointed out that they provide an improved gripping of tube 10 around penis 5 so that penis 5 is secured within tube 10 by suction action with no leakage. Shown also, are a spherical enclosure 30, vent holes 36 to allow air to enter enclosure 30, and proximal entry 32 in enclosure 30 holds tube 10 securely in place.
(14) FIG. 2 illustrates further the character of interface portion 110 including rigid disc 50 shown edgewise, which may be a circular flat object secured within distal end 14 of urine tube 10. It is pointed out that urine tube 10, being of an elastomeric material, may be stretched around the periphery of disc 50 to hold it in place axially relative to urine tube 10. Disc 50 has a central hole 14 which accepts proximal end 22 of interconnection tube 20 securing it in place with a tight fit. Fluid sensor 62 may be mounted on disc 50 as shown and as will be described may be functional in the process of generating suction when urine is present within urine tube 10. It is suction that draws urine from tube 10 to tube 20. One or more electromechanical vent valves 40 are contained within enclosure 30 and mounted through holes in disc 50 which secures valves 40 in place. Valves 40, when open, provide air flow into urine tube 10 but prevents fluid from passing outward (one-way valve). Valves 40 are of such size as to allow some air to enter tube 10, and while suction overcomes the tendency of pressure rising due to this air inflow, to maintain a negative pressure within tube 10 suction is increased to compensate. Fluid sensor 62 may also have a companion sensor to monitor air pressure (suction). Connector 70 is used to allow separation of interconnection tube 20 to allow a more comfortable management of the joining of urine tube 10 with the penis 5 or the urethra and to allow a user to move about freely when the apparatus is not being used. Electrical wires (see FIG. 9) will also be disconnected at that time. Ano-ring 72 is used to seal connector 70.
(15) FIG. 3 illustrates the joining of urine tube 10 with the female urethra 3 at the urethral orifice which is adjacent to the tissue surface of the vestibule. As shown, urine tube 10 may be flared or forced into a flared condition thereby conforming opening 12 as a suction cup type joint for improved suction holding.
(16) FIG. 4 shows an enablement wherein urine tube 10 is engaged with an undergarment 80 such as an underwear, under-pant, panty, diaper or similar item worn by an individual when using the apparatus. As shown, urine tube 10 may be inserted through an opening or a slit, fold, etc. 82 in undergarment 80, wherein opening 82 may have a strong elastic edge or closure capable of helping to hold urine tube 10 in place so that axial movement between urine tube 10 and undergarment 80 is minimized and loss of suction attachment is also minimized. In this case urine tube 10 is secured in place by both garment 80 as well as by suction as previously described.
(17) In FIG. 5 case 200 may include a hinged cover 205 as shown. Cover 205 may have a digital processor system 208 mounted within. System 208 may be a Seetec model W759 digital processor with seven-inch LCD monitor resistive touch panel and WIFI, Bluetooth, and GPS communication capability or any equivalent as will be known to those of skill in the art.
(18) In FIG. 6, as shown, case 200 may enclose graduated canister 210 with its attached, sealed lid 215. Case 200 may also house motor driven vacuum pump 220 with its attached shut-off valve 230 and vacuum gauge 240. Suction tube 250, may interconnect shut-off valve 230 with canister lid 215 and may include filter 260 which may be used to prevent vacuum pump oil from traveling upstream into canister 210 and also may prevent bacteria from traveling downstream to reach pump 220 where it would be exhausted to the environment. Vacuum pump 220 may be powered by AC current via power cord 270 as shown, or alternately may be powered by a DC battery pack with inverter (not shown). Suction (low pressure) in canister 210 is developed in interconnection tube 20 and urine tube 10 for application at penis 5 or urethra 3 as previously described. Urine, when present, is therefore sucked through urine tube 10, interconnection tube 20, and into canister 210 where it can be analyzed. In like manner, other fluids may be suctioned into canister 210 for analysis.
(19) FIG. 7 illustrates graduated canister 210 with lid 215. As described, urine is delivered into canister 210 via interconnection tube 20 which is fitted to inlet 217 of lid 215. Suction is applied at fitting 218 of lid 215. Sensors 280a, 280b, and 280c are representative of a wide variety of sensor and sensory materials that may be utilized in characterizing collected samples of urine or other fluids. Such sensors may be mounted, as shown, in strips on the interior side surface of canister 210 as shown or may have another form and may be mounted in other ways. Such sensors may be used to detect liquid level, trace chemicals, biological agents, occult blood, and other foreign agents or components of collected urine as described in the foregoing Brief Discussion of Related Analytics.
(20) FIG. 8 illustrates vacuum gauge 240 capable of reading vacuum in mm Hg on the inner scale and inches of Hg on the outer scale with higher vacuum (stronger suction/lower pressure) increasing in a counter-clockwise movement of the gauge's indicator. Suction of about 5 inches (145 mm) Hg is controlled as a maximum set point by gauge 240 so that valve 230 is automatically closed when vacuum level attempts to exceed this value thereby preventing damage to the penis sheath or to the tissues of the labia minora/vestibule. Vacuum operations include two modes: Standby and Active. In Standby mode, a low level of suction is created after which vacuum pump 220 is shut down. This low level of suction maintains attachment of the proximal end 12 of urine tube 10 to penis or urethral aperture. During standby mode valves 40 and 240 are held closed to preserve suction for the maintenance of attachment of urine tube 10. Standby mode may be held throughout the night, but if urine enters tube 10 while the system is in Standby mode, urine sensor 62 immediately triggers Active mode operation through computer 208. Sensor 62 signals computer 208 which causes pump 220 to turn on and valves 40 and 240 to open. Suction is generated at urine tube 10 which overcomes air inflow through valves 40 to maintain suction which forces urine through tubes 10 and 20 and into canister 210. When sensor 62 no longer detects the presence of urine, the reverse occurs so that the apparatus resumes the Standby mode. In an alternate mode of operation, vacuum pump 220 may be on during standby to assure that enough suction is produced to hold attachment of urine tube 10 as described above. FIG. 10 shows the above operation in detail.
(21) FIG. 9 shows how several interconnections between components of the described system are joined. Computer 208 controls operations. Urine tube 10 is joined to the urethra by suction during Standby mode. When urine enters urine tube 10 urine-sensor 62 detects it and signals computer 208 which, in turn, signals vacuum gage 240 and opens vacuum valve 230 and also turns on vacuum pump 220. Computer 208 signals inlet valves 40 thereby opening them. With vacuum pump 220 now operating and with vacuum valve 230 open, suction is applied through vacuum tube 250 and canister 210 and interconnection tube 20 and urine tube 10 which flushes the urine into canister 210. When urine sensor 62 no longer senses urine in urine tube 10 the signal to computer 208 is extinguished and signals are sent to inlet valves 40 and, through vacuum gauge 240 to close vacuum valve 230 and close-down vacuum pump 220. In the alternative, standby mode may be entered with vacuum valve 230 and/or vacuum pump 220 throttled to achieve a low suction level as monitored by vacuum gauge 230. When urine is present in canister 210 sensors 280 determine the presence of, and quantitative characteristic of several species within the urine such as: proteins, drugs, occult Blood, sodium chloride (NaCl), and other elements, compounds, and substances. Such content may be determined down to micro levels using one or more of the techniques described in the foregoing Brief Discussion of Related Analytics. It is within the skill level of those experienced in the computer arts to define an algorithm or software program such as defined in FIG. 10 to carry out the processes described in FIG. 9. It is within the skill level of those experienced in systems engineering to define a means for interconnecting the components of the apparatus as shown in FIG. 9.
(22) It should be recognized that the described apparatus may be adapted for use with animals other than humans. For instance, there is a need for taking and analyzing urine samples of farm animals such horses, mules, cows, and non-farm animals and other mammals.
