Detail description of preferred embodiments
Further description of structure or technical terms involved in the present invention is stated as follows:
Test strip
Reagent strip applied to the present invention can be common transverse lateral flow reagent strip. In the prior art, specific structure and testing rules for such reagent strip are well known to common technicians in this field. Common reagent strip includes specimen collection area, marking area, test area and water absorption area; specimen collection area includes specimen collection cushion; marking area includes marking cushion; water absorption area includes water absorption cushion; furthermore, test area contains essential chemical substances that can detect analyzed substances. Common reagent strip is mainly represented by nitroate cellulose reagent strip. In other words, nitroate cellulose is provided in the test area, to which, specific adhesion molecule is attached to display test results; alternatively, it is also applicable to use cellulose acetate membrane or nylon membrane, etc. Normally, width of reagent strip is between 3mm and 6mm, which can be 4mm in a particular embodiment.
According to detailed description hereinafter, referred text attached to illustrations is an integral part of this document, which provides description of particular embodiments for the present invention through illustrations. It is not excluded that other particular embodiments are also applicable to the present invention, and structure of this utility model can be changed within the coverage of the present invention.
According to the present invention, test strip 400 as applicable to the electric reading device contains graphic information that can be identified by the electric reading device, which can identify different positions of numerous areas on the test strip through analysis on graphic information. In a particular embodiment, such graphic information is represented by a barcode as shown in FIG 4-8. Each area on the test strip or information in each area can be distinguished through analysis of barcode 401 and 4021 on the test strip 400 by the electric reading device. In the present invention, barcode 401 and so forth on the test strip 400, can cover on the front surface of test strip 400 through printing or typing to facilitate identification for users. Nevertheless, it is also convenient for identification by the electric reading device. In a further particular embodiment, upper surface of test strip 400 is covered by adhesive tape, on the surface of which barcode 401 is printed.
In a particular embodiment, numerous areas are isolated by the barcode 401 on the test strip 400; in another embodiment, however, area 402 and 403 are isolated by the barcode 401 on the test strip. In a further particular embodiment, the size of area 402 and 403 on the test strip 400 is the same as shown in FIG4, which can facilitate the electric reading device 100 to read information. In a particular embodiment, widths of area 402 and 403 are both 10mm with height equivalent to the width of test strip 400.
To ensure accurate differentiation of area 402 and 403 on the test strip 400 by electric reading device 100, identical image or barcode is not provided at the same position corresponding to the two areas. In other words, area 402 and 403 are free of identical information that can be read by the electric reading device.
In a particular embodiment, two areas as isolated by barcode 401 on the test strip 400 comprise test area 403 and product information area 402, which are in the same size. In a particular embodiment, position and size of test area 403 is the same as that of practical test area on the test strip 400; thus, it can ensure accurate and effective acquisition of test results of specimen on the test strip 400 by the electric reading device. Furthermore, product information area 402 also consists of another barcode 4021 and 4023 and so forth, containing information on specific product types as tested by the test strip 400. Particularly speaking, different test strips can be normally used to test such different products like HCG, marijuana and morphine, etc. after treatment. Differentiation of types of products as tested by the test strip is a problem to be solved when such test strips used to test different products require the same testing equipment to read test results. Arrangement of product information area and barcode in it serves as a technical solution to solve this problem. Different barcodes in the product information area represent different product types as tested by the test strip. In other words, a particular barcode represents a particular product type as tested by the test strip.
In a particular embodiment, to identify each area and information demonstrated respectively, barcode 401 in the isolated area of the test strip 400 is different from barcode 4021 in the product information area 402. In a particular embodiment, the two can be in different colors; whereas profile of the two barcodes is different or both profile and color of the two barcodes are different in a further particular embodiment.
In a particular embodiment as shown in FIG 5 and 6, barcode 401 in the isolated area and barcode 4021 in the product information area belong to ID barcode. To identify differences between the two, width and space of the two ID barcodes is varied in some embodiments. In a particular embodiment, width of isolated ID barcode 401 is 4mm; whereas that of ID barcode 4021 in the product information area is 1mm; height of the two ID barcodes is equivalent to the width of test strip. Different width of the two barcodes is convenient for identification by the reading device. In a further particular embodiment, color of the two ID barcodes is different; isolation ID barcode 401 is in orange color; whereas ID barcode 4021 is in red color. In this case, to ensure more obvious comparison in the color of barcodes, external surface of test strip is in white color. When the external surface of test strip is in white color, while isolation barcode and ID barcode are in orange and red color respectively, obvious contrast among the three colors and excessive color differences are favorable for identification and definition by the reading device, and thus ensure accurate reading of relevant information.
In a particular embodiment as shown in FIG 6, test area 403 on the test strip includes a control line 4031 for control over test results; such control line is used to judge if test results of test strip 400 is valid. As shown in FIG 7 and 8, display of corresponding test results— test line 4032, is still available when relevant products are tested by the test strip 400. Both control line and test line are in the test area, of which, profile and color are not limited on condition that they can be read and identified by the electric reading device. In a particular embodiment, both control line and test line are in strip lines. More particularly, color of marked object used in combination with test strip, control line and test line are in the same color with gold mark, namely purple.
To prevent any error to identification product information area 402 and test area 403 by computing element 103, test line 4032 and control line 4031 as indicated by potential test results of all products in the test area 403 are not provided in the product information area 402.
The present invention also involves an electric reading device that can read test strip as shown in FIG1. Reading device 100 of the present invention includes an image acquisition element 101, an image transmitting element 102 and a computing element 103. Image acquisition element 101 can obtained relevant images, in particular, image of at least two areas on the test strip 400; whereas transmitting element 102 aims at information transmission between image acquisition element and computing element. Image acquisition element of the present invention aims to transmit image acquired to the computing element 103 through transmitting element 102. Computing element 103 of reading device 100 can convert graphic information as acquired on the test strip 400 into a series of values, namely grouping values to facilitate differentiation of each area on the test strip 400 through analysis of such grouping values.
In a particular embodiment, a limit value H is preset for the computing element 103; a series of values as converted from images, namely grouping values are to be compared with limit value H for the computing element to obtain isolation positions among such values. According to the present invention, preset limit value H is an empirical value as calculated based on empirical data. In an embodiment, such limit value H can be any value between 0 and 255. In a preferred embodiment, limit value H can be selected between 0 and 50, and it can be 4 in a particular embodiment. Isolation point for corresponding images will be defined through analysis of isolation positions of such values as obtained by computing element 103. According to the present invention, isolation point on each image refers to the boundary point of each graph on the image or boundary point indicating variation to the color of such graph. After that, computing element 103 will identify isolation blocks on the image through comparison in space between each isolation point on the image so as to further identify areas as isolated by the isolation block on the image through comparison in space between each isolation block.
In a further particular embodiment, once at least two areas are obtained on the image of test strip 400 through calculation, computing element 103 will further differentiate grouping values in each area for comparison with valve value P prior to judgment of information in each specific area based on comparison results. According to a specific approach, values in each area are to be compared with valve value P to define area information based on the comparison results. For instance, a consequential value is preset to represent one certain area, such as a for area A, b for area B, c for area C and so on. In a further particular embodiment, one certain value S can be preset to differentiate different areas. In other words, once the grouping values in the area are compared with valve value P, specific area information is to be defined through comparison of compared results with preset value S. For instance, compared results over the preset value S is to be defined as area A; whereas that below and equal to the preset value S is to be defined as area B and C respectively. Furthermore, preset value S can be deemed as a range for definition of specific area information based on interrelation between comparison results and the range of preset value S. For instance, compared results within this range are to be defined as area A; whereas that below or out of this range will be defined as area B and C respectively.
According to the present invention, valve value P is preset within computing element 103, which can be either a single value or a value within the certain range. Nevertheless, it can be also represented by numerous fixed values. It is applicable to set valve value or different fixed values when valve value P is represented by numerous fixed values. In a particular embodiment, once grouping values in each area are compared with each set fixed value, results identical or corresponding to fixed value will represent the certain area defined as a specific area.
In a further particular embodiment of the present invention, computing element 103 can compare grouping values in each area with a set value K to obtain a series of binary values; such binary values will be further compared with fixed binary values as preset in each area; when the two are identical, this area shall be defined as one certain area. It is applicable to define one or more fixed binary values as preset in each area or a range value. In a practical embodiment, if binary value as obtained in the area is the same as one of fixed binary values, the specific area information can be confirmed. However, to ensure accurate differentiation of difference among numerous areas by computing element 103, fixed binary values as set for each area are different. In a particular embodiment, if numerous binary values are set for one certain area, fixed binary values set in another area will not cover the set binary values. In the present invention, the set value K is defined between 0 and 255 based on empirical data; whereas the preferred one is between 0 and 50. In a particular embodiment, the set value K is 4. In a particular embodiment, any value in each area is to be compared with the set value 4; any value over and below 4 is to be set as 1 and 0 respectively so as to obtain a binary value for each area, such as 0101 or 00000101, etc. The binary value as obtained is to be further compared with one or more fixed binary values as preset for each area; any binary value identical to one certain fixed binary value in one certain area shall represent the defined area.
In some particular embodiments, preset fixed binary values in each area are provided with corresponding data definition table to identify information in each specific area; furthermore, such data definition table aims to indicate specific information in each area. Therefore, it is applicable to identify specific implications of each defined area, and obtain information contained if the obtained binary value is identical to one certain binary value through comparison with the fixed binary value in the area. Detailed description of a particular embodiment is stated as follows: As shown in FIG 2 and 3, testing device 200 is used in combination with test strip 400 to test various products, and to quickly convert test results into relevant information for reflection on the computer or other electric systems as connected; once such information is acquired by the operator, reading device 100 is to be scattered in the testing device 200. The testing device 200 comprises a fixing device 300 for placement of test strip 400, a base 201 and a shell 202. The testing device 200 also includes an image acquisition element 101 comprising two parts— a camera element 203 and a plane mirror 204; image of test strip 400 within the testing device 200 (the image covers at least two areas on the test strip) is transmitted to the camera element 203 through reflection by the plane mirror 204; the camera element 203 acquires corresponding image through photographing. To ensure precise photographing, such testing device also includes a separator 205, a hole 2052 corresponding to the cam on the separator, a LED lamp 2051 and light barrier 206, 208 and 209 and a plane mirror fixing plate 207. As shown in FIG 3, the testing device 200 also includes a transmitting element 102, a transmitting element 210 (102) connected with camera device 203, a transmitting element interface 211 on the testing device and an opening 210 on the shell for placement of transmitting element interface 211. Transmitting element 210 is connected with camera device 203; whereas image of test strip 400 as stored in the camera device is to be transmitted to the follow-up element connected through connection of transmitting element 210 with transmitting interface 211. In a particular embodiment, the testing device is connected with the computer or computerized system for transmission of corresponding graphic information.
As shown in FIG 4, 5 and 6, barcodes 401 are on the external surface of test strip 400; such barcodes 401 divides test strip into area 402 and 403. Wherein, to enable computing element of reading device 100 to effectively identify practical test area on the test strip and corresponding test results , area 403 serves as test area, which has the same position and size as practical test area on the test strip 400. Whereas another area 402 is on the external surface of test strip, which aims to indicate types of products as tested by the test strip 400. To facilitate analysis and computation by computing element 103, area 402 and 403 are in the same size. Area 402 can be at any position on the surface of test strip (except for test area). In a particular embodiment, area 402 is in the marking area of the test strip or on the external surface corresponding to the water absorption area, which is adjacent to test area. Area 402, namely product information area, designed with another ID barcode 4021 and 4023, aims to reflect information on product types as tested by the test strip through such barcodes in the product information area of the test strip. Digits of barcode in the product information area are defined as per practical demands. In a particular embodiment, the barcode comprises 4 digits; whereas that in a further particular embodiment comprises 8 digits. As shown in FIG 5 and 6, ID barcode 4021 in the product information area 402 indicates that the test strip 400 aims to test one certain substance in the specimen, such as morphine. Whereas ID barcode 4021 and 4023 provided in the product information area 402 shown in FIG 8, indicates that the test strip 400 aims to test another substance in the specimen, such as marijuana. Isolation barcode 401 may have the same color as the ID barcode 4021 in the product information area 402 (See FIG 5). However, the two may have different colors as shown in FIG 6-8. Particularly speaking, isolation barcode 401 may be in orange color; whereas ID barcode 4021 in the product information area 402 is in red color. To differentiate isolation barcode 401 and ID barcode 4021 in the product information area 402, certain space 4022 is to be reserved between barcode in the product information area 402 and isolation barcode 401, to facilitate effective identification of information by the reading device 100.
ID barcodes in the product information area are isolated by interval. As shown in FIG 8, interval 4024 is used to isolate ID barcode 4021 and 4023. Normally, interval 4024 aims to indicate corresponding information on product types through combination and arrangement with ID barcode 4021 and 4023. In an embodiment, ID barcode 4021 in the product information area has the same width as interval 4024. Once the test strip 400 is placed into the fixing device 300, leaving the side with barcode oriented upwards, further place fixing device 300 into the testing device 200. At this point, testing device 200 will start to work, and LED 2051 will lighten areas isolated by the barcode on the test strip 400. Plane mirror 204 will reflect such areas forward the camera device 203, which will further proceed with photographing, and transmit images to the follow-up computing element 103 through transmitting element 210 for corresponding analysis and treatment.
Firstly, computing element 103 will convert graphic information obtained into a series of values or grouping values prior to comparison with preset limit value H, namely 4, inside the computing element. Once the isolation position of such grouping values is obtained, further obtain isolation points on the image obtained based on the isolation position, namely isolation point 411, 412, 413, 414, 415, 416, 417 and
418 on the test strip. After that, computing element 103 will further obtain isolation block 421, 422, 423 as well as 4021, 4023, etc. through comparison in space between each isolation point. Once all isolation blocks are obtained, computing element 103 will obtain area 402 and 403 through analysis of space between each block for further comparison between information in area 402 & 403 and set value K-4 to obtain a binary value. In area 402 as shown in FIG 5, 6 and 7, the binary value as obtained is 00000001; whereas the binary value obtained in area 402 shown in FIG 8 is 00000101; the binary value obtained in area 403 as shown in FIG 5, 6 as well as 7 and 8 is 00000000, 00100000 and 00100100 respectively. Area 402 and 403 are defined as product information area and test area respectively through comparison between such binary values and a series of fixed binary values in the two area of computing element 103 (to facilitate differentiation of the two areas by computing element 103, preset fixed Binary values in the two areas are different; furthermore, identical barcode or image are not set at the same position in the two area on the test strip 400; for instance, barcode information is not provided at the position corresponding to the area 402 if test line and control line are provided; particularly speaking, if the binary value as provided for the test line and control line simultaneously is 00100100, it will not be set within the product information area). Furthermore, specific products as tested by the test strip are to be obtained based on the binary value in the corresponding product information area. For instance, if preset value 00000001 in the computing element indicates that the product tested is morphine, what tested by the test strip as shown in FIG 5 and 6 is morphine as contained in the specimen. Test results of morphine are to be obtained comparison between test line 4032 and control line 4031 in the test area 403.
In a particular embodiment as shown in FIG 7, information in area 402 as obtained by computing element through analysis and comparison of information on the test strip is 00000001; whereas that in area 403 is 00100100. Area 402 is defined as product information area based on the preset value in the computing element. Barcode marking in this area indicates that the product as tested by the test strip is morphine; area 403 serves as test area, in which, test results are valid and positive. Such information is to be reflected by the computing element for acceptance by the operator to complete corresponding test.
