Abstract

[Solution]
In particular, a dual chamber apparatus for receiving and containing a liquid such as urine uses a generally cylindrical body having a removable top cover and an inner transverse funnel shaped wall. The transverse wall has a central circular orifice and divides the body into lower and upper chambers, each containing a forward flow and midpoint urine fluid sample. The lower chamber floatable orifice stopper is responsive to the pre-flow liquid filling the lower chamber to a predetermined height for closing the orifice, and the subsequent mid-point flow urine liquid is contained in the upper chamber . An annular float below the orifice stopper ensures proper stopper closure of the orifice. The bottom cover has an upright stopper push column and a flexible spring-like annular web adjacent to the periphery of the cover. When urine fluid is collected in the device and the device is pushed down into the bottom cover, the web flexes and the bottom cover column pushes the stopper firmly into the orifice, preventing leakage between the two chambers. Therefore, the stopper is locked into the orifice beyond the center. Other mechanisms for locking the stopper within the orifice include urine liquid releasable compression springs, urine liquid expandable hydrophilic materials, urine liquid activated boiling tablets, magnet elements and urine liquid activated adhesives. Disclosed. As the bottom cover flexes and pushes the stopper into the orifice, a microscopic hole in the device body above a predetermined urine level in the lower chamber exhausts air pressure from the lower chamber.

Description

  The present invention relates to the general field of devices for collecting and separately containing two samples of liquid, and more particularly to the separate containment of two samples of body fluid, and more particularly to analytical use. Collection of two samples of urine and separate accommodation.

  Under current circumstances, the desire or need for liquid sample collection and separate containment is often advocated. As an example, bacteriuria analysis requires the collection of a stream of what is commonly referred to as “midpoint flow” urine, as described below.

  The best mid-point flow urine specimen for bacterial diagnostic testing is a very precise 10-step using various disinfectants currently available by catheter insertion or in a wide range of mid-point flow urine collection systems Obtained directly from the patient's bladder by following the body cleaning techniques. In general, these redundant and very dull cleaning procedures are not followed at all, especially by younger female patients, due to ignorance or difficulty of acceptance.

  In addition to the inadequate cleaning process and the fact that a useful collection system that can capture and separate midstream urine specimens has not been available to date, the high incidence of false positive diagnostic results is Always remind us of the pitfalls in managing clinical urinary tract infections.

  The first part of the patient's urine flow is called pre-flow urine. Especially in women, this pre-flow urine is contaminated and unsuitable for urine analysis, especially for microbiological or bacteriological tests, while flowing through the external genitourinary tract, which is not well washed Always regarded as a thing. More frequently, forward flow urine contaminants produce high false positive results in experimental tests. This result is unfortunately derived from external contaminants located around the anatomical part of the external urogenital tract. These seemingly innocent false positive contaminants are dragged along with a clear clean urine flow from the bladder during the excretion process. This unintentionally contaminated forward flow urine is collected in a conventional single chamber collection container immediately after rinsing through the patient's genitourinary pathway, followed by subsequent cleaners, midpoint flow samples and Mixed and poorly mixed midpoint flow samples are considered inappropriate or unacceptable for experimental diagnostic procedures.

  A problem associated with midpoint flow urine collection as described above is to ensure proper cleaning of the preflow urine stream (not used for bacteriological analysis). If the flow of the pre-flow urine is very small, it will cause an improper washout of the urogenital pathway and subsequently contaminate the midstream urine flow collected, thereby allowing bacteriological urine analysis. It can cause adverse effects. On the other hand, if the pre-flow urine flow is very large, the patient may produce a mid-flow urine flow that is insufficient in quantity for urine analysis purposes (typically 6 to 12 ml is required) )

  So far, according to the inventors' knowledge, the most commonly used mid-flow urine collection procedure is presumed to be sufficient for the patient to rinse off the anatomical pathway. Continuously urinates into the toilet bowl (or other receptacle) in an amount of about 30 ml to about 50 ml of urine (which is later discarded), and cleaner for the uncontaminated mid-flow urine flow required It is required to provide a sample to collect the subsequent urine flow for analysis and finally complete urination into the container. In such procedures, the amount of pre-flow urine that is discarded is usually difficult to control for women, and if it is very low, it results in a contaminated mid-point flow urine flow, The midpoint flow urine flow can be very small for accurate biological analysis. Moreover, such a procedure requires that the patient not interrupt her (or his) urine flow to collect midpoint flow. This can make it difficult to collect midpoint flows. In any case, such treatment can cause unintended unhygienic urination into the patient's hand and / or urine collection container.

  Thus, as a first step, providing a device that automatically collects a pre-flow urine flow by a predetermined amount and then automatically collects a mid-flow urine flow as a second separate sample. Highly desirable. More importantly, the collection device completely separates the second clean midstream urine sample from the first pre-flow urine sample to prevent contamination of the midstream urine sample.

  Another example of the need to collect two simultaneous separate urine samples from the same individual relates to an individual drug test. Two simultaneous urine samples, usually from drug-tested individuals, are desirable even if not legally required, especially where legal issues are or could be included. The first of these urine samples is used for spot drug testing, and the second one of urine samples is the one where the drug test results at the spot suspect legitimacy and is involved in a legal struggle In other cases, it should be maintained or maintained in a preserved state that cannot be modified to perform subsequent drag tests, thus requiring a second drag test.

Accordingly, a primary object of the present invention is to provide an apparatus for receiving and holding two types of liquid, particularly urine samples, with the two types of samples being separated from each other.

  The dual chamber liquid receiving and holding device includes a liquid receiving and holding body having a continuous outer wall, an open top and an open bottom, and includes a removable top cover and bottom cover for the body. Preferably, the device body formed in a substantially cylindrical shape is formed with a substantially funnel-shaped transverse inner wall that divides the body into an upper liquid receiving and holding chamber and a lower liquid receiving and holding chamber. The walls are tapered downward toward the transverse inner wall orifice to allow fluid flow communication between the upper and lower chambers. Preferably, an annular depending locking flange surrounding the orifice has a narrow inner annular locking recess.

  An orifice stopper disposed within the lower chamber is responsive to the liquid filling the lower chamber to a predetermined height, and causes the stopper to float into a sealed engagement with the orifice, thereby lowering the lower chamber. Prevent further liquid flow into it. The stopper is preferably formed with a narrow outer annular bead configured to latch into the locking flange annular recess when the stopper is securely received within the orifice. The orifice is circular in shape and is located in the center of the transverse wall, and the stopper is formed with an upper conical orifice sealing area.

  The stopper is preferably formed with a circular skirt region extending outward. A ring-shaped float having a height selected to provide a predetermined liquid height in the lower chamber is located below the circular skirt region of the stopper to provide the stopper with stability when levitated Preferably it is done.

  The device body has a narrow bead around the outside adjacent to the open bottom, and the bottom cover is configured to snap upward beyond this body bead for attachment of the bottom cover to the body. ing. Also preferably provided is a bottom cover locking ring that is sized to fit over the bottom cover, the bottom cover locking ring being attached to the body to secure the bottom cover to the body. It is configured to be linked to the form of the body so that it can be attached by screwing.

  The device according to the deformation comprises an adapter for diverting the strong flow of liquid contained in the device through the open top, the adapter being otherwise adapted to stop the liquid contained in the lower chamber. The stopper can be prevented from sealing tightly into the orifice when it floats into the orifice. The deflection adapter includes a mounting member removably attached to the open top of the apparatus body instead of the top cover. The dome-shaped element attached to the attachment member is positioned directly above the stopper when the attachment member is attached to the device body and when the stopper is levitated into the orifice by the liquid contained in the lower chamber. Be placed. The dome-shaped element is configured to divert the strong flow of liquid received in the device to the region of the transverse wall surrounding the orifice. The attachment member comprises a handle and means for removably attaching the handle to the attachment member.

Preferably, means are provided for pushing the stopper into a tight sealing relationship with the orifice so as to ensure that no liquid leaks between the upper and lower chambers.
In one aspect, the stopper pushing means comprises an annular spring-like flexible web formed in the bottom cover around a bottom cover region that extends downward, the web extending to the bottom of the device. In response to pushing down into the cover area, engage the center upright area of the bottom cover with the stopper and push the stopper up into the orifice to force the orifice against liquid leakage through the stopper. In order to provide a tight seal, the stopper outer annular bead is deflected upward in such a manner that the stopper outer annular bead is hooked into the locking flange annular recess. When the web bends upward so that the upright area of the bottom cover pushes the stopper firmly into the orifice and locks the stopper outer annular bead into the locking flange annular recess, the web is between the upper and lower chambers. In order to ensure that no liquid leaks over the stopper, the stopper is locked over the center to lock it into the orifice and the stopper outer annular bead is hooked into the locking flange annular recess.

  Preferably, it comprises a bottom cover extension sized to attach to a downwardly extending bottom cover region, the bottom cover extension being larger to ensure fixation beyond the center of the web. The size is sized to provide an installation area for the device body and an additional height for the bottom cover region extending downward.

  The dual chamber device according to the deformation comprises a spring arranged in the lower chamber below the stopper held in compression by the fiber disk. The disc is spring-loaded so that the spring engages with a stopper and pushes the stopper upward into the orifice and latches the stopper outer annular bead into the locking flange annular recess to securely seal the orifice. In response to contact with the aqueous liquid contained in the lower chamber for a predetermined length of time, preferably at least about 20 seconds, to soften the disk sufficiently to release it from its compressed state; In order to ensure that no liquid leaks over the stopper between the upper chamber and the lower chamber, the spring engages the stopper and pushes the stopper upward into the orifice so that the orifice is secured. The stopper outer annular bead is locked in the annular recess of the locking flange to seal It was.

  According to another variant, the dual chamber device comprises a hydrophilic element which is arranged in the lower chamber below the stopper and is very expandable with an aqueous liquid. The hydrophilic element responds to contact with the aqueous liquid contained in the lower chamber, thereby greatly expanding the element into contact with the stopper, pushing the stopper upward into the orifice, The stopper outer annular bead is hooked into the locking flange annular recess to securely seal the orifice, and the stopper is orificed to ensure that no liquid leaks through the stopper between the upper and lower chambers. Pushing further inwardly, the stopper outer annular bead is hooked into the annular recess of the locking flange.

  In yet another variant of the dual chamber device, the stopper pushing means comprises a liquid-dissolvable effervescent tablet disposed in the lower chamber below the stopper. The effervescent tablet provides a large amount of gas bubbles that rise to contact the stopper in response to contact with an aqueous liquid contained in the lower chamber, thereby pushing the stopper upward into the orifice. In order to tightly seal the orifice, a stopper outer annular bead is latched in the locking flange annular recess.

  In a dual chamber device according to a further variant, the stopper pushing means comprises a secondary bottom cover having a central region extending upwardly through the bottom cover, the central region comprising an elongated upright stopper engaging pin Have A removable spacer is placed between the bottom cover and the secondary bottom cover to maintain separation between the covers before use. Move the secondary bottom cover pin upward to force the stopper into the orifice when the spacer is removed, and the weight outside the device and the liquid contained within it will be outside the stopper to tightly seal the orifice The annular bead is hooked into the locking flange annular recess. The spacer is removed, the secondary bottom cover pin pushes the stopper firmly into the orifice, the stopper outer annular bead is hooked into the locking flange annular recess, and the device is pressed down onto the secondary bottom cover Thereafter, the secondary bottom cover is snapped upward across the bottom cover, causing the secondary bottom cover pin to lock a stopper within the orifice, and the stopper between the upper and lower chambers. The stopper outer annular bead is hooked into the locking flange annular recess to ensure that no liquid leaks through.

  The stopper pushing means of the double chamber device according to still another modification comprises a magnet element fixed to the stopper and another magnet element fixed to the transverse wall adjacent to the orifice, and the orifice before use of the device A removable spacer disposed between the stopper and the orifice to prevent magnetic attraction of the stopper into the liquid when the liquid is introduced into the lower chamber to the extent that the stopper floats into the orifice; The stopper is securely magnetically pulled into the orifice, and the stopper outer annular bead is latched into the locking flange annular recess by a magnet element to securely seal the orifice. When the stopper is pulled firmly magnetically into the orifice and the stopper outer annular bead is hooked into the locking flange annular recess, the magnet element will allow liquid to pass through the stopper between the upper and lower chambers. To ensure that there is no leakage, the stopper is further locked into the orifice and the stopper outer annular bead is hooked into the locking flange annular recess.

  In yet another variation of the dual chamber device, an aqueous liquid activated adhesive is applied to the transverse wall around the orifice and a removable spacer prevents the stopper from sticking into the orifice prior to use of the device. Therefore, it is disposed between the stopper and the orifice. When liquid is introduced into the lower chamber to raise the stopper into the orifice, the adhesive is activated so that no liquid leaks through the stopper between the upper and lower chambers. The stopper is locked in the orifice to ensure that

  In a dual chamber apparatus according to a further variant, a deflecting means is provided. The diverting means is a liquid that is received into the device through the open top to prevent the stopper from sealing tightly into the orifice when the liquid contained in the lower chamber raises the stopper into the orifice. It is provided to divert the powerful flow. The deflecting means includes a mounting member removably attached to the open top of the apparatus body instead of the top cover, and a stopper that is inserted into the orifice when the member is attached to the apparatus body and by liquid contained in the lower chamber. And a dome-shaped element attached to the attachment member so as to be in a position directly above the stopper when levitated. The dome-shaped element is configured to divert the strong flow of liquid received within the device into the region of the transverse wall surrounding the orifice. A handle and means for removably attaching the handle to the attachment member are provided.

  The device body is composed of a rigid plastic material, which preferably comprises a high density polypropylene. Further, the upper and lower chambers preferably have a volume of about 80 ml and about 100 ml, respectively, for use in a device for urine collection.

  In general, an elongate handle and means for removably attaching the handle to the upper region of the container outer wall are provided so that the handle protrudes substantially radially from the upper region. The handle is formed with a gripping area that is angled upward and outward when the handle is attached to the container outer wall.

  Any version of the dual chamber device comprises an elastomeric member located on the container outer wall in the region of the lower chamber, the elastomeric member being able to remove liquid from the lower chamber It can be pierced with a needle. The elastomeric element is automatically sealed after the hypodermic needle is withdrawn from the puncture site. Preferably, a cover is provided that securely covers the elastomeric element, the cover being detachable from the elastomeric element, but cannot be reattached to the elastomeric element after removal, so that the liquid in the lower chamber can be removed. Provides a visual indication that a tamper has occurred.

  Pressure release means may be provided to evacuate air from the lower chamber so as to prevent liquid withdrawal from the lower chamber to the upper chamber caused by pressure. The pressure release means may comprise a pinhole formed in the lower chamber above the predetermined liquid level through the side wall of the device body, the pinhole preferably being 0.01 mm or more Having a diameter between about 0.1 mm.

A top cover or cap 104, a bottom cover or cap 106 attached to the open bottom of the body, and a bottom cover locking ring 108 screwed onto the body to secure the bottom cover to the body (as described below). And an angle forming handle 110 detachably attached to the body by a taper forming attachment 112 protruding from the upper region of the body. The hole 120 (shown in a highly exaggerated size in all relevant figures for clarity) can be about 0.01 mm to about 0.05 mm in diameter.

  The top cover 104 is shown in FIG. 2 as having an annular device that seals the recess or groove 116. The handle 110 has a mounting region 118 at its distal end that is sized and sized to fit upwardly into the body attachment 112 (FIG. 4) in the form of a tapered tongue and groove. When the dual chamber apparatus 100 (and variations thereof described below) is used to collect pre-flow and mid-point flow urine samples, the handle 110 is particularly easy during urine sample collection. It is designed to be ergonomically convenient and effective for use by female patients to provide access. Thus, the handle 110 preferably has an overall length L1 that can be about 4.5 inches and a central bending angle α that can be about 45 degrees, and further includes a handle mounting area 118 and a device body. Mounting part 112 attaches the handle at an upward angle β of about 30 degrees combined with angle α (FIG. 1).

FIG. 5 shows a top view of the device body 102, which can be constructed from a rigid plastic material, such as high density polypropylene, for example, which can be transparent, translucent, or opaque. As shown in the longitudinal section of FIG. 6 and Figure 6a, device body 102 includes an outer wall 124 of a height H ₁ which can be about 3.5 inches for urine specimen collection, which may be about 2.5 inches the open top 126 having an outer diameter D _1, is formed having an open bottom 128 having an outer diameter D _2, which may be about 2.25 inches. The body wall 124 may have a thickness T ₁ that is about 0.05 inches.

  A first outer threaded top cover receiving area 130 is formed on the adjacent body wall 124 below the open top 126 and a second outer threaded bottom locking ring receiving area 132. Is formed on the adjacent body wall above the open bottom 128. The outer annular bead 124 is formed around the body wall 124 at the bottom open end 128.

Formed across the device outer wall 124 is a funnel-shaped transverse inner wall 140 that divides the device body 102 into an upper chamber 142 and a lower chamber 144. These chambers have urine collection volumes of about 80 ml and about 100 ml, respectively. Central circular orifice 146 in the transverse inner wall 140 has an inlet opening with a diameter D ₃ which may be about 0.80 inches, and is formed by a peripheral orifice ring 148 hanging down. The orifice ring is formed in a conical shape, that is, slightly expanded in diameter toward the lower chamber 144.

  A narrow colored ring 136 on the outer surface 138 of the body wall 12 adjacent below the first threaded region 140 is provided as a visual “full” guide when liquid is introduced into the upper chamber 142. Has been.

Hanging from the transverse inner wall 140 and surrounding orifice ring 148 and extending below it is a stopper retaining ring 150 having an outer diameter D ₄ that can be about 1.25 inches. A narrow shallow inner annular stopper retaining groove or recess 152 is formed around the stopper fixing ring 148 adjacent above the lower edge 156 of the stopper fixing ring.

The buoyant orifice stopper 160 shown in FIGS. 7-9 is approximately 1.25 inches with a hollow conical orifice sealing area 162 and a lower radially extending skirt area 164. obtained, the whole has a height _{H 2.} Orifice seal area 162 is formed and sized to fit tightly within the orifice ring 148 described above, thereby sealing orifice 146. Surrounding the lower region of the orifice sealing area 162 is an annular locking bead 166 sized and sized to fit closely within the stopper locking ring annular locking groove 152 (described above). is there. What forms part of the orifice stopper 166 is a hung guide or push column 168. What is formed around the lower region of the guide or column 168 is a sawtooth-shaped annular retaining ring 170 (FIGS. 7 and 8).

As shown in FIGS. 8 and 9, several (six shown) internal stiffeners 172 are provided to impart stiffness to the orifice seal region 162. The stopper 160 is preferably made of the same rigid plastic material as the device body 102. The orifice stopper skirt portion 164 preferably has an outer diameter D ₅ that can be about 0.59 inches at the lower skirt peripheral edge 174. Column 168 has an outer diameter _{D 6,} which may be approximately 1.97 inches.

The annular orifice stopper float portion 180 shown in FIGS. 10 to 12 is preferably made of a closed polystyrene foam so as to have buoyancy. As will be described later, the float portion 180 is formed and sized so as to provide buoyancy to the orifice stopper 160. For such purposes, the float portion 180 has a diameter D ₇ that can be about 1.0 inch at the inner surface 182 to loosely fit over the orifice stopper guide or column 168, and the orifice stopper The outer surface 184 has an outer diameter D ₈ that can be about 1.57 inches to fit loosely below the skirt region 164. The upper peripheral region 186 of the float portion 180 is chamfered at an angle of about 45 degrees so that the float portion fits below the orifice stopper skirt region 164. Float portion 180 is, for example, have the _second thickness T _2, which may be about 0.39 inches, and is selected according to the desired liquid accommodating volume of the lower chamber 144 (FIG. 6). The float portion 180 allows the device body 102 to tilt according to the patient's skill while discharging urine (or other liquid) into the lower chamber 144, even if the orifice stopper is itself buoyant. Even when done, it functions to lift the orifice stopper 160 into engagement with the orifice 146.

As shown in FIGS. 13-17, the bottom cover 106 having an overall height H ₃ that can be about 1.06 inches is recessed with a rigid upper side having a diameter D ₉ that can be about 1.18 inches. A central bottom base 190 is provided. The central bottom base 190 is surrounded by a thin, flexible upper arcuate annular web 192 that has spring characteristics and may be about 0.63 inches above the bottom base lower surface 194. distance _{d 1} extends. The radially outer end of the web 192 terminates in a first device body mounting flange 196 that extends annularly upward, the flange 196 facing inwardly and an annular upwardly extending direction. A second device body sealing flange 200. Projecting upward from the bottom base is an orifice stopper guide 208. Formed around the inside of the guide 208 is an orifice stopper retaining ring 210 that is formed in a complementary manner to the orifice stopper retaining ring 170 (FIGS. 7 and 8). Has been. Outer diameter _{D 10} of the guide portion 208 may be about 0.75 inches.

  The bottom cover 106 is attached to the apparatus body 102 and is shown in the side views of FIGS. 15 to 17 (shown by dotted lines). FIG. 15 shows the bottom cover 106 with the annular web 192 in its uncompressed state. FIG. 16 shows the bottom cover 106 with a web 192 (not shown) in its compressed state. This compression state is achieved by pushing down to the bottom cover resting on the rigid surface 211 until the base region 190 is no longer visible. FIG. 17 is a longitudinal cross-sectional view (corresponding to FIG. 14 and derived from FIG. 16), with the bottom cover web 192 beyond its center as a result of the bottom cover 106 being pushed down onto the surface 211. Deflection to the stop state, thereby pushing the orifice stopper 160 upward into a tightly sealed relationship with the orifice 146 is shown. This locks the stopper locking bead 166 in the orifice locking recess 152 and locks the stopper in the orifice to ensure that no liquid leaks between the upper chamber 142 and the lower chamber 144. It includes a process.

The bottom cover 106 is preferably composed of a relatively high density polypropylene that is less stiff than the device body 102 so that the web 192 can flex in the manner described above. Due to the relative flexibility of the bottom cover 106, the offset push of the bottom cover deflects the web 192 to its locked state beyond its center, thereby pushing the stopper 160 firmly into the orifice 146 and pushing the stopper. It is unlikely that it will lock into it (as described above, an area of the bottom cover flange 196 is sufficient to allow liquid leakage from the lower chamber 144). May be moved from). To avoid this very unlikely possibility, the device body threaded so that a bottom cover locking ring 108 made of the same rigid plastic material as the device body 102 locks the bottom cover 106 to the device body. It is screwed firmly into area 132.
(Double chamber apparatus 100a according to the first modification)
The double chamber apparatus 100a according to the first modification shown in the form of being disassembled and aligned in FIG. 18 includes the above-described double chamber body 102, top cover 104, bottom cover 106, and bottom cover locking ring. 108, handle 110, orifice stopper 160, orifice stopper float 180, top cover sealing ring 212, bottom cover locking ring / bottom cover sealing ring 214, and orifice stopper sealing ring 216. The sealing rings 212, 214 orifices 216 are preferably constructed from rubber (eg, neoprene) or elastomeric plastic (eg, silicon).

  In the above-mentioned range, the above-described double chamber apparatus 100 is included in the double chamber apparatus 100a, and is formed so as to distinguish the features, but has an additional bottom cover height (defined below). Is identical to the dual chamber apparatus 110a described above except that it is a circular bottom cover extension member 220 that fits over the central bottom cover base 190. The extension member 220 includes an annular mounting flange 222 that is sized to attach the member to the bottom cover central base portion 100 and extends upward. The inner surface 223 of the flange 222 has a curvature that matches the curvature of the bottom cover web 192. The flange 222 is preferably colored red to facilitate visibility. Forming part of the member 222 is an enlarged flat circular support plate region 224 that doubles the “installation area” larger than that provided by the central bottom cover base 100. Provided to chamber apparatus 100a to ensure over-center locking of bottom cover web 192 as well as consequent locking of orifice stopper 160 to orifice 146. The support plate 224 is formed with a relatively thin, narrow annular perimeter locking region 226 that mates with the bottom cover locking ring 108, as will be described in more detail below. The support plate region 224 has a central opening 225 that allows the extension member 220 to fit upward into the bottom cover region 190.

Further shown in FIG. 18 is first a threaded area 230 inside the top cover 104 where the sealing ring 212 is received, and a bottom cover locking ring where the sealing ring 214 is received. And a similar threaded region 232 inside 108. The top cover threading area 240 is screwed with the threading area 130 on the device body 102, and the bottom cover locking ring threading area 232 is screwed with the threading area 132 on the device body. As shown in FIG. 19, bottom cover locking ring 108 has a central aperture 240 of diameter _{D 11} which may be about 2.09 inches. For flap 241, the diameter _{D 12} which may be about 1.97 inches.

The dual chamber apparatus 100a is shown in FIG. 20 in its fully assembled state before use. Bottom cover extension support plate region 224 is shown as having a diameter D _13. The bottom cover extension 220 provides a distance d ₂ from the surface 211 to the bottom cover locking ring 108 that is greater than the above-described bottom cover height d ₁ (FIG. 14) and can be about 0.55 inches. This distance d ₂ is dual chamber device 100a may represent the total amount of deflection of the bottom cover web 192 when pressed downwardly into the surface 211 as shown in FIG. 21 representing a state after the use of dual chamber device ing. In this regard, the red color of the bottom cover extension region 222 is no longer visible when the device 100a is in a compressed state after use as shown in FIG.

  In FIG. 22, the double chamber apparatus 100a is shown in longitudinal section with its fully assembled top cover 104 prior to use removed, thus corresponding to FIG. 20 without the top cover 104. The orifice stopper 160 is attached to the stopper adjacent to the lower portion of the stopper region 162 and is shown at the lowermost position below the orifice 146 and rests on the bottom cover guide column 210. The float ring 180 is shown in its lowest position resting on the bottom cover web 192. The bottom cover seal portion 214 is shown in a state of being installed on the bottom cover locking ring 108, and its threading region 232 is shown in a state of being screwed to the threading region 132 of the apparatus body.

  In the longitudinal sectional view of FIGS. 23 and 23a, which is similar to FIG. 22 but represents the subsequent operational phase of the dual chamber device 100a, a liquid 250 such as a patient's urine is placed in the upper chamber 142 of the device body 102. Shown as being released. The lower chamber 144 is shown already filled with liquid (urine), which pushes the orifice stopper 160 upward on the float 180 so that the stopper region 162 is pushed into a sealing relationship with the orifice 146. On the other hand, the liquid is beginning to fill the upper chamber 142. Assuming that the device 10a was used for collection of patient urine for bacterial analysis, the urine 252 contained in the lower chamber 144 should consist of pre-flowed urine, and thus the lower chamber. Has a sufficient volume to ensure that the urine 254 collected in the upper chamber 142 forms a clean mid-point flow urine. The upper surface 253 of the urine 252 matches the predetermined urine height in the lower chamber 144 so that the orifice stopper 160 is lifted up to this height into sealing engagement with the orifice 146. Respond to.

  A vertical support column 168 depending from the orifice stopper skirt region 164 is nested within a larger diameter guide column 208 extending upwardly from the bottom cover 106. Thus, the upward movement of the orifice stopper 160 is completely guided and restrained in the bottom cover guide column 208. At this point, the bottom cover annular flexible web 192 remains undeflected prior to use of the device.

  The orifice stopper locking ring 150 stabilizes the stopper sealing area 162 so that it is directed into the orifice 146 whenever the device body 102 is tilted at various angles during its use. Thus, regardless of how each patient places her (or his) device body 102 during the liquid (urine) collection process, including pre-flow urine capture, separation and accurate orifice stopper sealing and closure The mechanical integrity of the full-duplex chamber apparatus 100 is always maintained and does not impair the stabilizing action of the float 180.

  24, 24a, similar to FIGS. 23, 23a, the dual chamber device 100a is shown after its use, with the top cover 104 attached to the device body 102 and the handle 110 removed from the member 112. Is shown in the state. The device 100a is shown pressed down on a hard surface 211 so that the bottom cover base region 190 and the bottom cover extension 220 are fully retracted into the device body 102. In this state, the bottom cover column 210 pushes the orifice stopper 160 upward into a tight sealing relationship with the orifice 146 and the stopper seal 216 is pushed in a sealing relationship with the lower region of the orifice ring 148. This process locks the stopper locking bead 166 in the orifice locking recess 152 and locks the stopper in the orifice to ensure that no liquid leakage occurs between the upper chamber 142 and the lower chamber 144. Each step is included. In this state, the colored bottom extension flange 222 is hidden, thereby providing a visual indication that proper locking has occurred. Occasionally, a nervous and poorly knowledgeable patient can leave the dual chamber device 100a unlocked. This red colored flange 22 is clearly visible to nurses and technical staff and can immediately remind them to lock them to the device 100a before transporting it to the analytical laboratory. .

  As a result, locking beyond the center of the bottom cover web 192 causes the bottom cover 190 to lock in its upper position as shown, thereby ensuring that the orifice stopper 160 is within the orifice 146 (as described above). Lock to. Thereby. Despite the rough operation of the apparatus 100a, the liquid 252 cannot leak from the lower chamber 144 to the liquid 254 held in the upper chamber 142. The bottom cover locking ring 108 provided with the seal 114 prevents liquid leakage around the bottom cover 106 that may have occurred if the device 100a was not properly pressed against the surface 211 during the locking process. To prevent. When the bottom cover base portion 100 to which the bottom cover extension 220 is attached is retracted upward as described above, the bottom cover extension peripheral latching region 226 is bent downward and the bottom cover adjacent to the central opening 240 is formed. The locking ring radial protrusion 241 is bypassed and then protrudes outwardly across them, keeping the bottom cover web 102 locked beyond its center.

  Assuming that the lower chamber liquid 252 is forward flow urine and the upper chamber liquid 254 is midpoint flow urine, the upper chamber midpoint flow urine is used for bacterial analysis and is The device 100a that still contains flowing urine is discarded.

  Device 100a or device 100 (without bottom cover extension 220) deflects bottom cover web 192, and bottom cover center region strut 190 and bottom cover extension (for device 100a) into lower chamber 144. It will be appreciated that when pushed down to push upward, the volume of the lower chamber decreases, causing high air pressure in the lower chamber region above the liquid 252. This high air pressure is sufficient to cause the liquid 252 to flow out of the lower chamber 144 beyond the orifice stopper 160 and into the upper chamber 142, which can contaminate the upper chamber liquid 254. A device body hole 120 is provided for venting air from the lower chamber 144 to relieve internal pressure and thereby prevent the liquid 252 from flowing past the orifice stopper 160.

  However, under some circumstances it may be necessary to have access to the urine 252 in the lower chamber 144 after the orifice stopper 160 (and variations thereof) is locked in the orifice 146 as described above. Or it may be desirable. For example, when testing a drug in an individual's urine, it may be necessary or legally required to preserve the reservation or second part of the individual's urine specimen in a manner that does not tamper with it. If a spot drag test is discussed and proof is required, the spot drag test will be performed on urine 254 obtained from the upper chamber 142 and the second urine 252 portion (as described above) ) Retained in the lower chamber 144 until required to verify the result of the spot drag test.

However, after the orifice stopper 160 is locked in the orifice 146 as described above, the stopper cannot be released from the orifice without destroying the device 100a. Accordingly, for use in drag testing of the dual chamber apparatus 100a (and other variations of the dual chamber apparatus described herein), the lower chamber 144, as represented in FIGS. The outer wall 138 of the device body 102 in this region has a self-sealing syringe access port 260 covered by a removable plastic or hard plastic protective cap 262 tapped in place and thermally sealed. ing. As shown in FIG. 26, after the protective cap 262 has been removed, it cannot be reattached by hand, thereby ensuring an unobtrusive specimen in the lower chamber 144, It provides a visual indication that urine 252 in 144 may have already been accessed and processed in such a way as to adversely affect urine drug testing. Syringe needle 264 is inserted through port 260 and attached syringe 266 is used to withdraw a certain amount of urine 252 from lower chamber 144 that can be used for a secondary drug test.
(Double chamber apparatus 100b according to the second modification)
The inventors have found that a strong rapid flow of liquid 250 (eg, urine released from a female patient) into the device upper chamber 142 that impinges on the orifice stopper 160 prevents proper orifice sealing when the stopper floats into the orifice 146. It was determined that it could cause stopper stoppering to the extent possible. As a result, within the scope of the present invention, as shown in FIGS. 27 to 31, it is possible to provide a flow escape sanitary barrier adapter 270 that constitutes a part of the dual chamber device 100 b according to the second modification. include.

  What is shown with a flow escape sanitary barrier adapter 270 is a peripheral mounting ring 272 and an equally spaced elongated downwardly angled beam 276 (four such beams are shown). And a central dome 274 supported from the mounting ring. The handle attachment part 112 a is fixed to the attachment ring 272 for receiving the handle 110.

  As shown in FIG. 29, the central dome 274 is placed directly over the orifice 146 and the stopper 160 when the flow escape sanitary barrier adapter 270 is snapped onto the upper edge of the device body 102a. As shown, the introduced urine flow 250 (shown in broken lines) flows down around the dome 274, reaches the transverse wall 140, and flows down to the side area of the stopper 160. This effectively reduces the liquid flow along the stopper.

A dual chamber device 100b according to a second variant is shown in FIG. 31 and shows that the handle 110 is detachably attached to a mounting part 112b formed on a deflector mounting ring 272. FIG. The dual chamber device 100b is the same as the device 100a described above except that the handle 110 is attached to the sanitary barrier adapter 270 and the handle attachment part 112 is not attached to the device body 102a. In an embodiment, the interior is configured and operates in the above-described manner of apparatus 100a. After the liquid is released into the body 102a, the adapter 270 with the handle 110 attached is removed from the device body 102a and discarded. Adapter 270 provides a hygiene barrier to maintain the bactericidal properties of body 102a from being unintentionally contaminated by contact with the patient's unclean outer body region. The top cover 104 is screwed into the device body 102a to seal the device 100b for subsequent urine analysis.
(Double chamber apparatus 100c according to the third modification)
Locking of the orifice stopper 160 into the orifice 146 in a more automatic manner (as described above with respect to the devices 100, 100a and 100b) will cause the bottom cover web 192 to be centered beyond its center in at least some situations. It will be appreciated that this is more desirable than the mechanical locking method described above, which requires the dual chamber apparatus 100 or 100a to be manually depressed to deflect to a stop state.

For this purpose, FIGS. 32 to 38 show a spring-type orifice stopper locking assembly 280 for a dual chamber device 100c (FIGS. 35 to 37) according to a third variant. As shown, the locking assembly 280 includes a relatively small, preferably cylindrical housing 282 that includes a top 286 and cylindrical sidewalls 299. The housing base 290 is screwed upward into the bottom of the side wall 288 (FIGS. 32 to 33). The housing 282 has a height _{H 4,} which may be approximately 0.31 inches.

  As best shown in FIG. 33, a relatively large centrally located aperture 292 is formed in the housing top 286. The conical compression spring 294 is held inside the housing 282 by a circular member 296 fixed to the housing base 290, and is maintained in its compressed state by a spring holding disk 298 that is rigid and can be softened by an aqueous liquid. Yes. The disc can be formed from a suitable fiber material, such as cardboard, for example, and is positioned above the compressed spring 294 and directly below the top aperture 292.

A housing base 290 having a diameter D ₁₄ that can be about 0.63 inches is formed with a central liquid inlet aperture 300 and has a plurality of small short legs 302. These short legs 302 soften the spring retaining discs 298 and release the compression of the springs 294, separating the locking assembly 280 upwardly from the device bottom cover 106a and collecting the liquid collected in the lower chamber 144. (Urine) can enter the housing 282 through the base aperture 300. An air outlet 304 is provided in the housing sidewall 288. To facilitate screwing the housing base 290 into the housing sidewall 288, a groove 306 is formed in the base lower surface 308 (FIG. 34) to receive a screw driver blade.

  As shown in a longitudinal section in FIGS. 35 to 37, the dual chamber apparatus 100c according to the third modification incorporates the spring type orifice stopper locking assembly 280 described above. Shown to further configure the dual chamber device 100c are a device body 102b, a bottom cover 106a, an orifice stopper 160a, a float 180 and a handle 110. The double chamber device 100c eliminates the bottom cover locking ring 108 as unnecessary for the reasons described below.

  The device body 102b has the same structure as the device body 102 described above except that the lower threaded region 132a is formed directly above the lower end of the device body for screwable attachment of the bottom cover 106a. They are shown to be identical in point.

  The orifice stopper 160a is identical in all respects to the orifice stopper 160 described above, except that the sag column 170a is shorter than the column 170 shown in FIGS. 7 and 8 and is closed at the lower end 310. It is. The bottom cover 16a is formed with a peripheral inner threaded attachment region 312 that eliminates the annular web 192 and allows the base portion 194a to be generally flat and extend across the entire device body 102b. Except for the above, it is similar to the bottom cover 106 (FIGS. 13 to 17) described above. This peripheral inner threading attachment region 312 fits with the device body threading region 132a during assembly of the dual chamber device 100c.

  As shown in FIGS. 35-37, the compressed spring orifice stopper locking assembly 280 is within the column 208a, directly below the orifice stopper closed lower end or bottom 310, and the upper surface 318 of the bottom cover 106a. Is attached. Column 208a is formed with a plurality of vertical slits (not shown) to allow aqueous liquid access to locking assembly 280 and disk 298.

  In the pre-use state of the dual chamber apparatus 100c shown in FIG. 35, the orifice stopper 160a rests on the top 286 of the locking assembly housing 282 and the float 180 rests on the bottom cover upper surface 318. Yes.

  Corresponding to FIG. 35, but represented in FIG. 36, which represents the subsequent operation or use phase of the dual chamber device 100c, the orifice stopper 160a floats upward into a sealing engagement with the orifice 146, and the upper chamber To the extent that 142 is subsequently partially filled with liquid (urine) 154, liquid has been introduced into the dual chamber apparatus 100c having the lower chamber 144 filled. At this time represented, the spring retaining disk 298 is not sufficiently softened by the aqueous liquid 152 in the lower chamber 144 to release the locking spring 294 from its indicated compressed state.

  Preferably, immersion in an aqueous liquid (urine) for at least about 20 seconds is required to soften the spring retaining disk 298 sufficiently to release the spring 294. This allows sufficient time for the orifice stopper 160a to float upward into the orifice 146 to stop liquid flow into the lower chamber 144. This softening of the spring retaining disk 298 causes the spring 294 to release, which in turn pushes the disk upward through the housing opening 296, causing the orifice stopper 160 to enter a tight sealing relationship with the orifice 146. It expands to push it up further. At this time, the stopper seal portion 216 is pushed in a sealed relationship with respect to the lower region of the orifice ring 148. This process is performed between the upper chamber 142 and the lower chamber 144 by locking the stopper locking bead 166 in the orifice locking recess 152 and locking the stopper in the orifice, as shown in FIG. Ensure that no liquid leaks occur. FIG. 38 is an enlarged view of the region 38 of FIG. 37 showing the above-described operation of the spring-type orifice stopper locking assembly 180.

The above-described locking of the orifice stopper 160a into the orifice 146 by the orifice stopper locking assembly 280 is fully automatic and fills the lower chamber 144 of the device body without the need for manual intervention. It will be appreciated that it works only in response to liquid (urine) 154.
(Double chamber apparatus 100d according to the fourth modification)
A fourth dual chamber device 100d is depicted in FIGS. 39-40, which is a highly inflatable and hydrophilic to provide automatic locking into the orifice 146 of the orifice stopper 160a described above. The process is otherwise as described above with respect to the spring-loaded orifice stopper locking assembly 280 (FIGS. 35-38). They are similar and comparable.

  39, the expandable hydrophilic material capsule or element 330 is placed in the orifice stopper column 170 above the bottom cover 106a and in contact with the lateral stopper closing member 332. As shown in FIG. Has been placed. The orifice stopper column 168a rests on the hydrophilic material capsule 330 and the float 180 rests on the bottom cover upper surface 318 of the bottom cover 106a.

  As shown in the longitudinal section after use of FIG. 40 (corresponding to FIG. 39), the aqueous liquid (urine) 252 fills the lower chamber 144 and the liquid is the above-described opening in the column 208a. Flowing through and in contact with the hydrophilic material capsule 330, causing the material to expand significantly, thereby pushing the orifice stopper 160 upward into a sealing relationship with the orifice 146. An upward force is exerted on the stopper bottom portion 310, and at this time, the stopper seal portion 216 is pushed in a sealing relationship with respect to the lower region of the orifice ring 148. The process locks the stopper locking bead 166 into the orifice locking recess 152, thereby locking the stopper in the orifice and preventing liquid leakage between the upper chamber 142 and the lower chamber 144. Make sure.

Again, as in the case of a spring-type orifice stopper locking assembly 280, the use of the expandable hydrophilic material capsule 330 allows the liquid (urine) to fill the device body lower chamber 144 without manual intervention. ) Provide automatic locking of the orifice stopper 160b into the orifice 146 in response to 154 only.
(Double chamber apparatus 100e according to the fifth modification)
A double chamber apparatus 100e according to a fifth modification is shown in FIGS. The dual chamber 100e utilizes a gas generation assembly 340. The assembly includes an aqueous liquid active, effervescent tablet or element 342 disposed within a cylindrical tablet housing 344 to achieve automatic locking of the orifice stopper 160b into the orifice 146. The dual chamber device 100e is similar in many respects to both the dual chamber devices 100c and 100d described above.

  As shown in the longitudinal sectional views of FIGS. 41 to 44, the gas generation assembly 340 is installed in the orifice stopper column 168b and attached to the bottom cover upper surface 318 in the dual chamber apparatus 100e. As shown in the pre-use state of FIG. 41, the orifice stopper column 168 b rests on the bottom cover upper surface 318, such as a float 180.

  As shown in detail in FIG. 42, the gas generating assembly tablet housing 344 includes a top 350, a cylindrical side wall 352, and a bottom 354. The housing bottom 354 is formed with a plurality of small short legs 356 that upwardly separate the gas generating assembly 340 from the apparatus bottom cover upper surface 318 so that the liquid collected in the lower chamber 144 is In order to activate the effervescent tablet 342, it can enter through the aforementioned slits in the bottom cover column 208a and through the holes 358 formed in the housing bottom 354. A hole 360 is provided in the housing top 350 to allow the generated gas bubbles 362 to escape from the housing 344 (FIGS. 43 and 44). A hole 366 is formed in the housing sidewall 352 to allow air to escape from the housing 344 during the initial activity of the effervescent tablet 342.

As shown in the longitudinal cross-sectional view of FIG. 43, the gas bubble 362 rising from the gas generator 340 has the orifice stopper 216 pressed against the lower region of the orifice ring 148 in a sealing relationship. Push 160 up into a sealing relationship with orifice 146. The process locks the stopper locking bead 166 into the orifice locking recess 152, thereby locking the stopper in the orifice and preventing liquid leakage between the upper chamber 142 and the lower chamber 144. Make sure. Similar to the dual chamber devices 100c and 100d described above, when the lower chamber 144 is filled with aqueous liquid (urine) 152, the occurrence of the orifice stopper 160b into the orifice 146 without intervention by hand. Gas locking is achieved.
(Double chamber apparatus 100f according to sixth modification)
45 to 49, a double chamber apparatus 100f according to a sixth modification includes an apparatus body 102b, an orifice stopper 160c, a bottom cover 106b, an orifice stopper pressing base portion 380, a bottom cover and stopper pressing. A very soft removable sponge element 382 arranged between the base parts.

  45 and 47 with a bottom cover 106b, which is open at the bottom and ends in an upper tubular region 386 that extends to the upper side of the smaller diameter, extends to the upper centrally located position. A lower tubular portion 384. In other respects, the bottom cover 106b is the same as the above-described bottom cover 106a.

  Orifice stopper 160c is formed with an elongate centrally depending tubular pushpin guide 388 that fits securely within bottom cover upper tubular region 386. The orifice stopper 160c is placed on the upper end region 390 of the bottom cover lower tubular region 384 (FIG. 45) in a state before use of the dual chamber device 100f. In other respects, the orifice stopper 160c is substantially the same as the orifice stopper 160a described above.

  The push base portion 380 is formed with a flat bottom portion 392 in the center of which an upper extending column 394 that fits securely in the bottom cover lower tubular region 384 is located. Extending upward from the top 396 of the column 394 is an elongated orifice stopper push pin 400 that extends upwardly in a mating relationship through the orifice stopper pin guide 388. As shown in FIG. 45, the top 396 of the push base column top 396 is spaced substantially below the upper end region 390 of the bottom cover lower tubular region 384. The push base 380 is formed with a recessed well region 402 surrounding the column 394 where the sponge element 382 is accommodated. The recessed area is further formed by a perimeter mounting flange 406 configured to snap upward to the bottom cover 106b, as shown in FIG. The perimeter mounting flange 406 extends approximately 270 degrees around the push base portion 380 to provide adequate space for removing the sponge element 382 from the push base, as will be described below (FIG. 29).

As shown in FIG. 46, the sponge element 382 has a central diameter D ₁₅ that can be about 0.08 inches and a height H that can be about 0.4 inches to fit loosely around the column 394. _{And 5} . A relatively wide gap 410 is formed in the sponge element 382 to allow removal of the element from the push base recessed area 402. A thin protruding finger tab 412 is connected to the sponge element 382 on the opposite side of the gap 410. Before the liquid (urine) is introduced into the device 100f, the sponge element 382 is removed from the recess 402 of the push base and discarded. Friction between the column 394 and the tubular region 384 maintains the push base 380 at its front sponge removal conditions. A liquid (urine) filling device 100f is subsequently set on the surface 11 as described below.

  Use of the dual chamber device 100f is apparent from FIGS. When liquid (urine) fills the lower chamber 144 of the device, the orifice stopper 160c floats upward into a sealing relationship with the orifice 146, whereas liquid (urine) is collected in the upper chamber 142 of the device. Is done. Liquid 152 (urine) is collected in the lower chamber 144, and liquid (urine) 154 is collected in the upper chamber 142 installed on the surface 211. The weight of the liquids 152 and 154 in the liquid (urine) device body 102 b causes the device body with the bottom cover 106 b to be set downward into the push base recess 402, so that the stopper seal portion 216 is attached to the orifice ring 148. The push pin 400 pushes the orifice stopper 160c upward in such a manner that the orifice stopper 160 is pushed upward into a tight seal relation with the orifice 146 in a state where the orifice stopper 160 is pushed against the lower region. I will let you. The process includes the step of latching the stopper locking bead 166 into the orifice locking recess 152.

Following such downward placement of the device body 102b, the cover 104 is installed on the device body and the device 100f holds the push base portion 380 on the bottom cover 106b so that the push base peripheral flange 406 is at the bottom. It is manually pushed downward on the surface 211 so as to ride over the periphery of the cover in a snap manner. This locks the stopper 160c into the orifice 146, and even beyond the orifice stopper between the upper chamber 142 and the lower chamber 144 without the stopper being removed from the orifice (even if care is not taken). The apparatus 100f can be handled without leakage of the liquid (urine) 152.
(Double chamber apparatus 100g according to the seventh modification)
The double chamber device 100g according to the seventh modification shown in FIGS. 50 to 52 provides magnetic locking in the orifice 146 of the orifice stopper 160d in the manner described later. As shown in FIG. 50, the above-described orifice stopper 160d corresponding to the above-described orifice stopper 160b (FIG. 41) has a magnet member 420 attached to the lower surface 422 of the stopper skirt portion 164 around the surface. Formed. The magnet member 420 may constitute a single-part annular magnet and may include two or more magnet segments. A corresponding magnet member 424 is attached to the outer surface 426 of the orifice locking ring 150 spaced above the stopper magnet member 420.

  In order to keep the magnet members 424 and 420 separated prior to use of the device 100g, a removable soft-type sponge spacer 430 is disposed between the locking ring magnet member 424 and the orifice stopper 160d in a dual chamber. FIG. 50 shows the device body 102b initially installed. The molded spacer 430 is a separation region 432 formed in a conical shape, and a finger tab 434 is connected to the region. First, the orifice stopper 160d is placed on the bottom cover 106a so that the float portion 180 is placed.

As shown in FIG. 52, the spacer 430 is removed from the apparatus body 102b, and the orifice stopper 160d floats upward to the engaged state with the orifice 146 by the liquid (urine) collected in the lower chamber 142. When the magnet members 424 and 420 are attracted to each other, the stopper seal 216 is pushed in a sealing relationship with respect to the lower region of the orifice ring 148, and the stopper locking bead 166 is orifice locked. While locked in the recess 152, the orifice stopper is pulled firmly into the orifice 146, thereby locking the stopper in the orifice and causing liquid leakage between the upper chamber 142 and the lower chamber 144. Ensure that there is no.
(Double chamber apparatus 100h according to the eighth modification)
The dual chamber apparatus 100h according to the eighth variation shown in FIGS. 53-56 provides locking of the orifice stopper 160 into the orifice 146 by a liquid activated cement process in the manner described below. As shown in the pre-use state of FIG. 53, the double chamber apparatus 100h includes an apparatus body 102c, an orifice stopper 160, a float part 180, an orifice, and a bottom cover 106a. Orifice stopper 160 and float 180 are shown resting on bottom cover 106 a below orifice 146. A coating of aqueous liquid (urine) actuated cement (adhesive) 440 is applied to and around the inner surface 442 of the orifice ring 148 (FIG. 54) and is a flexible removable “release” 444. Is first protected by. The release can be made from wax paper or plastic material.

As shown in the post-use state of FIGS. 55 and 56, the “release” 444 is withdrawn from the orifice ring 148 and activated by exposing the cement coating 440 to liquid (urine) flowing into the device body 102b. Let As the liquid 252 is collected in the lower chamber 144, the orifice stopper 160 is lifted upward into a sealing engagement with the orifice 146, thereby contacting the activated cement coating 440 and the orifice The stopper is solidified in the orifice ring 148. This permanently locks the orifice stoper 160 and tightly seals within the orifice 148 so that the upper chamber 142 and the lower chamber 144 are independent of subsequent handling or mishandling of the dual chamber device 100h. Prevents the liquid 252 from leaking between.
(Summary of use of double chamber apparatus 100a as an example)
The operational usage of the double chamber apparatus 100a as an example is shown in each step in FIGS. 57A to 57H. When patients with dirty or less clean anatomical parts use the device 100a, an earlier pre-flow urine volume (40-70 ml) is considered quite useful. This is because the external genitourinary tract extending from the urethra to the device 100a is washed, rinsed and cleaned. Such a washing and rinsing mechanism forms a cleaner tube for the subsequent mid-point flow sample that flows through this same tube into the dual chamber apparatus 100a. Thus (see FIGS. 22-24) the dual chamber apparatus 100a is capable of capturing pre-contaminated flow urine that has been rinsed earlier and isolating the urine in a separate lower chamber 144. The dual chamber apparatus 100a continues to collect a later, cleaner midpoint flow sample in the upper chamber 142 separated from the lower chamber 144 by the orifice stopper 160. This separation and isolation. Can completely eliminate the mixing of contaminated pre-flow samples and clean mid-point flow samples in the dual chamber apparatus 100a (which has been described above for all the dual chamber apparatuses 100 and 100b-100h described above). ).

  FIG. 57A represents the dual chamber device 100a (with the handle 110 removed) in its assembled initial pre-use state and generally corresponds to FIG. 20 described above. The device body 102 is closed by the top cover 104 and then sealed by an adhesive sealing strip 450 marked as sterilized. This indicates that the device is in a sterilized state. The bottom cover 106 (not shown) is held by the locking ring 108 and rests on the bottom extension member 220.

In FIG. 57B, the handle 110 is shown fitted upward to the device body fitting 112 with the adhesive sealing strip 450 still in place. The handle 110 is shown in FIG. 57C with the device body mounting part 112 fully received.
