Description

APPARATUS TO TEST FLUID SAMPLES AND THE PROCESS TO MAKE THE APPLIANCE RELATED REQUESTS This is a partial continuation request of the U.S. Patent Application Serial No. 08/981, 665 filed November 5, 1997, which is a partial continuation of the registered Application Serial No. 08 / 613,487. on March 1, 1996.

TECHNICAL AREA The present invention relates to the collection and testing of fluid samples for narcotics of abuse, more particularly, with a multiple card for narcotics testing to visually identify the presence of narcotics of abuse in particular in urine and a process to make the test card.

BACKGROUND OF ART The increased availability and taking of narcotics of abuse by the general population has caused employers, government agencies, sports groups and other organizations to use tests for the detection of narcotics, as a condition of employment and in order to maintain the safety in workplaces. Typical tests for the detection of narcotics are carried out in order to quickly identify, on a qualitative basis, the presence of narcotics in a fluid body that may be urine. A complete analysis of the sample in a laboratory can then be carried out only if the preliminary detection results are positive. Increasingly, such narcotics detection tests are being carried out on site or in workplaces and, in general, they are carried out by personnel carrying out tests that are not technically trained, such as laboratory technicians. Therefore, it is important that the narcotics detection procedure be simple but reliable. Moreover, the The test apparatus should be such as to allow the personnel carrying out the test to avoid any contact with the sample of the fluid being tested. Different forms of apparatus have been proposed for the collection and collection of fluid bodies, such as urine, which have proved to be uncomfortable in their operation since they include a certain number of steps separately. Initially, the sample was collected and then several additional steps were required to transfer the urine sample to an apparatus for analysis. This multi-step procedure required the manual handling of the shows by means of different apparatuses and the use of said transfer apparatus caused spills that may result in contamination of the tester and surroundings. In addition, personnel who are not technical and who carry out urine sample screening tests objected to having any type of contact with the urine sample and even with the test same Many of the known apparatuses for carrying out the tests were complexes, since they included a container for the test and, consequently, it was necessary to transfer the sample, or at least a part of it, to another compartment of the container with In order to carry out the test. Said transfer of the sample required vigorous agitation of the container or turning of the head to empty the flow of the sample in a test compartment. Therefore, it was necessary to make the containers drip proof under said condition and the result was a complicated and expensive container structure. Moreover, the containers incorporated the structure because the test strips were mounted in a test compartment of the container and whose structure also allowed the fluid sample to flow into the test compartment to make contact with the test strips. Said assembly of the test strips later resulted in the complication of the container structure, since it was also necessary that a provision be made to be able to see the test strips from outside the container. This was generally achieved by providing a transparent window or other assembly of the test strips so that they were visible to the personnel performing the tests.

DISCLOSURE OF THE INVENTION Therefore, the main object of the present invention is to provide a novel and improved apparatus for testing samples of fluid bodies, particularly urine, for the detection of different narcotics of abuse at the same time. Another object of the present invention is to provide a novel and improved test card having a plurality of immune test strips for testing on one or both sides of said card and each of those strips is reacted to a particular narcotic of abuse. and has a visual endpoint to indicate the presence or absence of a particular narcotic. A further object of the present invention is to provide a simple and effective process for making said test card for detecting narcotics. The objects of the present invention are achieved and the disadvantages of the prior art are eliminated by means of the test apparatus for detecting narcotics of abuse according to the present invention which may be composed of a container in the form of transparent rate to contain the sample of urine to be tested. The open top of the container has a cover or lid and there is a diametral slit in the lid. The slit is such The size accommodates the test card having a plurality of immune test strips for tests mounted thereon in parallel on one side and each of said strips reacts to a particular narcotic of abuse. You can insert the test card through the slit in order to have one of the ends immersed in the urine sample to a depth my auntie hm i - irtii lMi f 'rn r - r í i i, t. m. n-nmi ») -tmurii, nv, -.-,, - iifr - wt ifa previously determined from where you can see the visual results of each test strip through the transparent side of the container without removing the test card from the container in order to indicate the presence or absence of a particular narcotic of abuse in the urine sample. In case the sample proves to be "positive" to indicate the presence of a narcotic in the urine, then it is necessary to send the sample to a certified laboratory to confirm the test. For this purpose, a second closure cap is provided which is solid, i.e., has no slit, which can be screwed into the open end of the container in the form of a rate. The test card is removed from the container, the solid closure cap is screwed in to close it, and then it is ready to be sent to the laboratory. As described above, the test kit includes an abuse narcotic detection device for collecting and testing a urine sample. This test apparatus contains a container in the form of a fee having a substantially transparent side and an open upper part in which a closure cover is screwed which is provided with a slit for receiving a test card. A second solid closure cap is provided which is threaded onto the outer end of the container in the form of a rate to seal it and allow the safe transfer of the sample of the fluid that is contained in said container. The test kit also includes a test card for the detection of narcotics of abuse, which may include a thin, flat member that is the size and shape of a business card. A plurality of immune test strips are fixed for side-to-side testing in a parallel fashion on one or both sides of the test card within the contour thereof. Each of the test strips is reactive in order to provide a visual indication in response to a particular narcotic of abuse. In this way, the presence of multiple analytes can be detected simultaneously with the test card.

WAYS TO CARRY OUT THE INVENTION ^ gí? gá ^ fe As can be seen in Figures 1 and 2, a test case for the detection of abuse narcotics 10 according to the present invention and which includes a container in the form of a transparent rate or rate is generally indicated. for the test 1 1 having a cylindrical side 12, a closed bottom 13 and an open surface 14. The cylindrical side 12 may be a little tapered or right. The open end 14 of the test rate 1 1 contains external threads 21 on which an outer closing cover or cover 22 provided with corresponding internal threads sits, which are not shown in the drawing. The cover 22 has a circular surface 23 from the periphery on which a cylindrical wall 24 rests on the inner surface, which is provided with internal threads. The surface cover 23 has a diametrical groove 19 which is shaped to accommodate a test card, as described herein. A solid cover or lid 15 is also provided that is similar in size and shape to the cover 22, but is solid or has no groove so that the covers 15 and 22 can be mounted interchangeably at the open end 14 of the rate of test 1 1. During its transfer, cover 15 is usually placed at the bottom of the test rate. A strip for measuring temperature 16 is mounted on the bottom of the side of the test rate so that it reacts to the sample temperature of the test within the test rate. The container is essentially a rate for samples, as is commonly used in medicine and has a wall made of a material normally impermeable to the samples of the fluids it contains. The container of any suitable material, such as thermal plastic, can be formed or molded. It is preferred that the container be transparent, since this allows the results of the test card to be read without having to remove it from the rate. But a transparent wall is not necessary and can be translucent or opaque. It is sufficient that the material has a degree of transparency with which one can distinguish the presence or absence of lines in the test part of the test strips through the wall of the container when the test card is close or even separated from the test. the wall of the container. While the rate shown is cylindrical, it should be understood that other non-cylindrical shapes can be used. A test card 25 is shown, which will indicate the presence or absence of any of the five different narcotic abuses, in Figure 1 where it is inserted into the slit 19 located in the closure cap 22 and in more detail in Figures 3-6. The test card is of multiple types of narcotics of abuse in which test strips are mounted for five different types of narcotics of abuse. The test strips 26-30 are spaced parallel to one of the test sides 31 of the test card and extend longitudinally on the test card from the top to the bottom thereof. These test strips indicate the presence or absence of the following narcotics Specific abuse problems: PCP, cocaine, amphetamines (AMP), marijuana (THC) and opiates. Test strips 26-30 may be of the type made by Bionike South of San Francisco, California, Phmatec of San Diego, California, Arista Biological of Bethlehem, Pennsylvania and American BioMedica Corporation of Hudson, New York. Said test strips are characterized as immune test strips and use colloidal gold chemistry. Each test strip is dipped to a maximum line indicated in 32 and the test results are read in a test area indicated in 33. A blue line in the test area indicates that the test is "negative" or the test absence of the narcotic of particular abuse in the test sample. The test strips can be completely removed, as shown in Figure 6, or partially through the slots in the card so that parts of the test strip can be projected above the test surface. 31 of the card, as shown in Figure 5. If the test strips are completely removed, then the strips will be covered by the upper surface of the upper fold, as shown in Figure 6. It is possible to that the test card is formed by two bends 34 and 35, as can be seen in Figure 7, and said bends in turn are formed of a simple strip having a fold or fold. The fold 35 is formed by a plurality of die cut slots 37 having the shape and size to receive each of the test strips. In this way, in the manufacture of a test card, the two parts 34 and 35 are bent over the end 36 and adhere to each other. Then, the test strips are placed in the slots, as indicated in Figure 6, and each of them adhere to the surface of the first part 34 on which the second part 35 has been folded. this modification, the test strips are covered with the test surface 31. It is also an object of this invention to make this test card of two separate or individual folds 34 and 35, which are then adhered to each other and the strips are placed in the slots, as described above. In order to carry out a test for detecting narcotics of abuse using the test card according to the present invention, the person who is being tested must first provide a urine sample at the transparent test rate eleven . The quantity of the sample provided must be such as to allow the insertion of the test card up to the maximum line indicated in 32. It is also possible to provide lines on the surface of the wall of the test container, which indicate how far it should be fill in. Then, the test rate is closed with a sufficient amount of the sample for the test by screwing the lid 22 on top of the test rate. The cover 22 includes a movable strip that adheres 18, which is placed on the slot 19. In this way, when the container with the sample for the test is carried to the person who is carrying it out, the strip is removed of protection 18 and the lower end of the test card is inserted to detect _dy & Narcotic multiple 25 in the slot until the bottom of the test card sits at the bottom of the test rate. Thirty to forty eight (30-48) ml of the sample will ensure that the bottom of the strip contacts it. The level of this amount of fluid will be a little below or above the top line 32. Then, the test card remains in place, at least, for three minutes and the test results can be read on each individual test strip through the transparent wall of the container. In this way, if a line that can be reddish blue or pink appears on any of the test strips, this indicates that the test is "negative" and the absence of that particular narcotic of abuse in the test sample. When you get a negative result, the urine sample and the container are discarded. If no such line appears, then the presence of any of the five narcotics of abuse in the sample is indicated. However, when the results of the test are positive, it is preferable to send the sample to a certified laboratory for confirmatory analysis by means of more specific test methods, such as gas chromatography or mass spectrometry. In order to send the sample into the container, the closure cap 22 is removed and the solid cap 15 is screwed into the open end of the container. Figure 8 shows a modification of the test card in 44. In this modification, the test strips are covered, but the relevant parts of the test and the sample strips ^^^^^^ ± m ^^^^^^^^^^^^^^^ * É t ** ^ * i¡Mm¡m test are exposed through the openings. The test card 44 comprises a central styrene fold 45, which has a thickness of 1.25mm corresponding to, or which is a little larger than, thickness of the test strips and slots are provided in the center fold to receive the test strips. The upper and lower faces of the central fold 45 are covered by a lower fold 46 and an upper fold 47, which can be made in one piece with double the material shown in the 48 and 49 to wrap around the central fold 45, as shown in Figure 10. The upper and lower folds can be made of a thin sheet of vinyl or cardboard covered with plastic. The upper fold 47 has a plurality of test windows 50 by means of which the results of the test can be seen by means of the test strips. At the upper and lower ends of the card there are openings for the sample 51, by means of which the liquid sample may have contact with the absorbent parts or receive the sample from the test strips. In Figures 10-16 there is shown a modification made to the test card 44, in which the card is made of three separate folds which are then removed. The upper and lower folds 46 and 47 are made of a thin sheet of vinyl that has a thickness of 0.33mm. The fold of the center 45 is made of styrene with a thickness of approximately 1.25mm. The upper fold 47 has, similarly, the test openings or windows 50, the openings receiving the sample 51 and the lower fold 46 is solid, *** - * as shown. The central fold 45 has a plurality of slots extending longitudinally 52 and a test strip 53 is inserted into each of these slots, as shown. The test strip generally has a length less than that of slot 52. In this representation, only one test strip for THC (marijuana) is shown. While the representation of the test card has a provision for five test strips, it must also be understood that the card can be made in the same way with less than five strips and even only with one strip if desired . In said modification, the sales 50 and 51 for the omitted slots are usually solid. Turning to Figure 17, at 54 a modification is made to the test card, which has test strips on both sides to increase the number of different narcotics that can be tested while maintaining the same size and configuration of the card test. The test card 54 has a front face or surface 55 which is the same front face 47 of the test card shown in Figure 10. However, the reverse side of this test card is shown at 56 in the Figure 18 and has an additional number of test strips, as shown. The number of test strips mounted on the reverse side of the test card may vary, as shown on the back faces of the test cards 57, 58 and 59 illustrated in Figures 22, 23 and 24, respectively. The test card 54 has folds or front and rear faces 55 and 56, a central fold 60 and intermediate folds 61 and 62. These intermediate folds are similar to the central fold 45 shown in Figure 1 1. These folds and panels are adhered to each other, as shown in Figures 19-21. For efficiency purposes, the intermediate folds 61 and 62 would be the same as the central fold 45, but only one or more of the slots 52 in the intermediate folds can be assembled with a test strip in said intermediate folds. In this way, five suitable test strips could be assembled in the intermediate fold 61 to match the narcotics of abuse, as shown in Figure 17 and one or more of these tests can be assembled in the intermediate fold 62 to match the narcotics, as illustrated in the back folds 56 in Figures 18 and 22-24. The front panel 55 has a plurality of test openings 63 and a plurality of windows or openings receiving the sample 64. These openings are positioned in such a manner as to correspond to the visual portions of the test and the portions receiving the sample from a sample. test strip 53. Similarly, each of the rear panels 56-59 has an adequate number of test windows 65 and windows that receive the sample or openings 66. The central fold 60 has no openings in order to maintain a separation between the test strips in the intermediate folds 61 and 62. In the process to make or assemble a test card of narcotics having test strips on one side, like the card 54 shown in Figure 17, the back panel 46 is fixed in its position by placing the card in a suitably configured cavity 67 in a template or guide 68. The cavity 67 has sufficient depth to accommodate the central fold 45 and the upper fold 55 for the cavity to effectively align the components of the test card in their proper positions. The template 68 may have one or more cavities 67. The back panel 46 may be placed in the cavity 67 by hand or by means of a machine. Then, a middle panel is placed, as in Figure 11, on the seated rear panel 46 that adheres to the middle panel. This central panel will have grooves extending longitudinally from side to side and in parallel and, then, an immune test strip 5 is placed for testing in one or more of these grooves. Subsequently, the front panel 55 is placed on the middle or central panel 45 to enclose the test strips. The front panel 55 has the appropriate test window 63, the window receiving the test 64, as described above. Then, the assembled test card having test strips on one of its faces is removed from the template. In order to make a test card of two. side, as illustrated in Figures 18 and 22-24, the assembled test card is turned over, as described, and repositioned in the cavity so that the face or front panel 55 is on the template. jgjg ^^ Subsequently, a second middle or central fold 45 is placed, which has adhesive on both sides, on the rear panel 46 and additional strips in the grooves of this second middle panel. Then a third panel, which forms a rear face 56-59 of the test card with two sides, adheres to the second middle panel. The completed two-sided test card, which will appear as shown in Figures 19 and 21 when viewed sideways, will then be complete and removed from the template. In order to protect the test card during its transfer and to prevent any deterioration of the test strips due to the atmosphere, the test card 54 is inserted, as shown in Figure 26, into a bag of tinsel 69 with the proper shape. The upper part 70 of the bag 69 is sealed to store the card completely and can be affixed with a stamp with the expiration date or any other information deemed appropriate. Each of the test strips 26-30 and 53 is a one-step immune assay in which a specially labeled narcotic (narcotic conjugate) competes with the narcotic that may be present in the sample by the limited number of mandatory sites in the sample. an antibody. The test strip consists of a strip of membranes in which a conjugate of narcotics has been immobilized. A complex of colloidal gold antibodies is dried at one end of the membrane. In the absence of any narcotic in the urine sample, the colloidal gold antibody complex moves with the urine sample by means of a capillary action to make contact with the immobilized conjugate of narcotics. An antigenic antibody reaction occurs forming a visible line in the test area. The formation of a visible line in the test area occurs when the test is negative for the narcotic. In this way, a simple test line indicates that the sample does not contain analytes or that its presence is below the cut level. When a narcotic is present in the urine sample, the narcotic or its metabolite will compete with the immobilized conjugate of narcotics in the test area for the limited sites of antibodies in the complex of antibodies labeled with colloidal gold. If a sufficient quantity of the narcotic is present, it will fill all the mandatory spaces available, thus preventing the antibody of the label from binding with the narcotic conjugate. The absence of a line or band of color in the test area indicates a positive result. In the membrane strip there is a control line or band that includes a different reaction of antigens / antibodies. The control line is not influenced by the presence or absence of the narcotic in the urine and, therefore, must be present in all reactions. In summary, without a single band in the control zone and none appears in the test zone, then the results are "positive", indicating that the particular narcotic is present and above a predetermined level that will vary of 25-1000ng./ml. Depending on the particular narcotic involved. If two color bands appear, one in the control region and one in the irittaiMiÉtaiki? test region, then the test results are "negative", which indicates that the level of said particular narcotic is below the predetermined sensitivity detection. If there are no bands of different colors visible in the control area or in the test area or if there is a visible band in the test area, but not in the control area, then the result is not valid, so it is recommended to retest the sample with another test card. The test card can also be used as a delivery system for biological detection or monitoring device by replacing the test strips with strips treated with suitable chemicals to react with different and biologically selected agents in military operations. Then, the strips can function in a manner similar to narcotic strips of abuse to provide a visual indication of the presence of a specific biological agent in a predetermined amount or the absence thereof.

INDUSTRIAL APPLICATION In this way, it can be seen that the present invention shows a novel and improved test kit for the detection of narcotics of abuse, which includes a container for the sample of the fluid to be tested and a test card for Multiple narcotics is introduced into the sample inside the container and the visual results of the sample are read on the test card at
