Description

Test piece reading device

Technical Field

The present invention relates to a test strip reading device, and more particularly, to a test strip reading device for reading a code.

Background

Test strip reading devices have been used to read samples or information carried on a particular test strip.

As shown in fig. 1A, the teststrip reading module 110 is embedded in a handheld device, such as a Personal Digital Assistant (PDA) or even a mobile phone, to form a simple personal palm-typeanalyte measuring device 100. In recent times, the handheld device is required to be light, thin, short and small, so that the teststrip reading module 110 must be light, thin, short and small in size and reduce power consumption, so as to meet the requirements of the handheld device and long-term operation. The conventionalanalyte measuring device 100 is configured with afront cover 101, a teststrip reading module 110, a position-limitingmember 103 for fixing the teststrip reading module 110, and aback cover 102, and measures a physiological parameter (such as blood glucose concentration, cholesterol value, uric acid concentration, or pH value) through a physiological sample carried on atest strip 120. Some analyte measuring devices can read different types of test strips, and in order to allow the analyte measuring device to add or confirm the type of test strip, a coding region can be formed at a certain position of the test strip.

For example, as shown in fig. 1A, fig. 1B and fig. 1C, thetest strip 120 is inserted into atest strip slot 143 formed by anupper support end 141 and alower support end 144 of the teststrip reading module 110, a plurality of holes 122 (e.g., the back of thetest strip 120 in the dashed line in fig. 1B) with different depths are formed at a certain position on thetest strip 120, and the teststrip reading module 110 has a mechanical code reading mechanism at positions corresponding to the plurality ofholes 122 in anupper module cover 140 and alower module cover 146, so as to detect and read the plurality ofholes 122 on thetest strip 120 inserted into the teststrip reading module 110, and decode theholes 122, so as to identify the type of thetest strip 120, assist the analyte measuring device to select a proper test configuration, and have an anti-counterfeiting function for thetest strip 120.

Such modules that read codes mechanically have problems that are practically applicable to the assembly and production of instruments. As shown in fig. 1B and fig. 1C, the components for detecting and reading the test strip coded signal and analyzing on the teststrip reading module 110 are disposed on thesame circuit board 153, thecircuit board 153 is located between the moduleupper cover 140 and the modulelower cover 146, and thegrounding strip 190 is located at the bottom of the modulelower cover 146, so that when the teststrip reading module 110 is assembled, the directions of placement and construction of the components (as shown by the dotted arrows in fig. 1C) are not consistent, and the assembly is not easy to be performed by manual means. In addition, thecircuit board 153 integrates the functions of detecting, reading signal and analyzing the test strip code, so that thecircuit board 153 needs to be thickened due to the complex functions and the increase of electronic components thereon. Since thecircuit board 153 is located between theupper module cover 140 and thelower module cover 146 and overlaps with the area of theoperation hole 142 of theupper module cover 140, the lower space of the area of theoperation hole 142 is enlarged to accommodate thecircuit board 153, so that the space of the teststrip reading module 110 is enlarged and must be thickened.

On the other hand, the sample on thetest strip 120 inserted by the test strip reading module may flow into the teststrip reading module 110 through the gap around theoperation hole 142 and theelectric contact portion 155, and contaminate the inside of the teststrip reading module 110, such as the electronic component (not shown in fig. 1B) on thecircuit board 153, so that the detection function of the teststrip reading module 110 is inaccurate. To avoid this problem, the teststrip reading module 110 is provided with a contamination-proof blocking member 160 around the code reading through hole, and theelectrical contact portion 155 is also provided with an electrical contactportion blocking member 161, however, the blockingmember 160 and the electrical contactportion blocking member 161 are separately provided, which is inconvenient in assembly.

Detailed Description

The following provides detailed embodiments of the strip code reading module, the strip code reading device and the biological detection system according to the present invention, and is referred to the drawings.

As shown in fig. 2A, 2B and 2E, thetest strip 220 is inserted into the teststrip reading module 210, wherein the upper supportingend 241 and the lower supportingend 244 of themodule 210 form atest strip slot 243. In order to increase the assembly speed of the teststrip reading module 210, the teststrip reading module 210 of the present invention separately sets the functions of detecting the coded signal of thetest strip 220 and reading the coded signal formed by thecode hole 222 of theanalytical test strip 220 on two different circuit boards, namely, afirst circuit board 253 for detecting the coded signal of the test strip and asecond circuit board 256 for reading the coded signal of the analytical test strip, wherein ashielding cover 248 is disposed on thesecond circuit board 256 to protect thesecond circuit board 256. Wherein the lower surface of themodule top cover 240 is provided with a plurality ofoperation holes 242 for sequentially accommodating the first stroke elements including theactuating element 250, theblocking element 260, agrounding plate 290 provided with a plurality of through holes, and amodule bottom cover 246 capable of accommodating theconductive element 270 and theelastic element 280. Thefirst circuit board 253 is disposed on the bottom of the module lower cover 246 (or the module upper cover 240), and is fixed by thefixing members 296, for example, by screws, and thegrounding plate 290 is disposed between the moduleupper cover 240 and the modulelower cover 246, that is, thegrounding plate 290 is disposed on theconductive element 270. As shown in fig. 2A and fig. 2B, such a configuration enables thefirst circuit board 253, thesecond circuit board 256 and related components of the teststrip reading module 210 to be assembled in the same direction (e.g. the direction of the dotted arrow) in a time-sharing manner, so that when the teststrip reading module 210 is assembled, different components do not need to adjust the original placement direction in order to match other components at each stage, and the assembly directions of the components are kept consistent, thereby being easily converted into an automated machine assembly, reducing the manual assembly requirement to accelerate the assembly speed, and improving the production efficiency.

Referring to fig. 1C, thecircuit board 153 and the modulelower cover 146 are overlapped up and down, so that the thicknesses of the two are overlapped. In fig. 2A, thesecond circuit board 256 with a thicker third thickness and a more complex assembly is cut off a rectangular area, and the original function of detecting the coded signal of the test strip in the rectangular area is shifted to thefirst circuit board 253 with a second thickness and located at the bottom of thelower cover 246 of the module. Since thefirst circuit board 253 has simpler functions, thefirst circuit board 253 is made of a thinner material and is arranged on the same side of the hollowed rectangular area, so that thefirst circuit board 253 and thesecond circuit board 256 are staggered up and down in the space of the modulelower cover 246, and thefirst circuit board 253 and thesecond circuit board 256 are not overlapped up and down, so that the second thickness of thefirst circuit board 253 and the third thickness of thesecond circuit board 256 are not overlapped, and the first thickness of the teststrip reading module 210 is not affected. Referring to fig. 2D, acircuit board 153 according to the prior art is disposed between the moduleupper cover 140 and the modulelower cover 146. Referring to fig. 2A and fig. 3A to fig. 3C, regarding the position relationship between thefirst circuit board 253 and thesecond circuit board 256 in the teststrip reading module 210 according to the present invention, it can be understood that thesecond circuit board 256 is located outside the space of the moduleupper cover 240 and the modulelower cover 246, so that the first thickness of the teststrip reading module 210 according to the present invention can be reduced. Preferably, the thickness is reduced by about 0.25 mm.

Referring to fig. 2E, the teststrip reading module 210 has twoelectrical contacts 255 disposed in the electricalcontact operation hole 257 at positions corresponding to the electrodes on thetest strip 220, and electrically connected to the electrodes on the test strip, so that thetest strip 220 inserted into the teststrip reading module 210 transmits the electrical signals of the physiological parameters measured by the physiological sample carried by thetest strip 220 to thefirst circuit board 253 of the teststrip reading module 210.

In order to overcome the problems of the conventional mechanical code reading module, especially to achieve the effects of reading accuracy, preventing contamination, and improving assembly convenience, the teststrip reading module 210 of the present invention has a sealingelement 264 integrally formed at the edges of theoperating slot 245 and the electricalcontact operating hole 257 to accelerate assembly and enhance the contamination blocking function, as shown in fig. 2C and 2E, the position relationship between the sealingelement 264 and the electricalcontact operating slot 257 is shown.

Referring to fig. 2E and fig. 3A, the position relationship of the electriccontact operation hole 257 and theoperation slot 245 of the moduleupper cover 240 and the sealingelement 264, and the position relationship of the moduleupper cover 240, the modulelower cover 246 and thefirst circuit board 253 are shown. Theelectrical contact 255 of the teststrip reading module 210 can be electrically connected to the electrode of thetest strip 220. When thetest strip 220 is inserted into thetest strip slot 243, the working electrode and the counter electrode on thetest strip 220 are electrically contacted with the twoelectrical contacts 255. Theelectrical contact 255 is preferably made of gold, and the corresponding test strip electrode is preferably made of gold, for example

The material used in the bloodest strip makes the current generated by the strip have better stability and conductivity. The coding structure of thetest strip 220 is not limited to the shape of the cavity, and can be selected from other designs, such as one of a bump, a sawtooth, a row of teeth, a slit, a groove, and a through hole, and is configured to operate with the teststrip reading module 210. The lower surface of theupper module cover 240 has anoperation slot 245, theoperation slot 245 is provided with a plurality of operation holes 242 for sequentially accommodating a first stroke component comprising a startingcomponent 250, ablocking component 260, agrounding plate 290 provided with a plurality of through holes, and alower module cover 246 capable of accommodating aconductive component 270 and anelastic component 280, thefirst circuit board 253 is disposed at the bottom of theupper module cover 246, wherein the bottom of the lower module cover is provided with a through hole for electrically connecting theelastic component 280 with the firstconductive region 234 of thefirst circuit board 253, in another embodiment, theupper module cover 240 has a plurality ofoperation slots 245 corresponding to and corresponding to the operation slots 245Each of the first and second operating stroke elements,ground plate 290 and modulelower cover 246 are configured.

Please refer to fig. 3A, which is a partial cross-sectional view of a test strip inserted into a teststrip reading module 210 according to a first embodiment of the present invention, wherein the teststrip reading module 210 of the present invention includes a moduleupper cover 240 having a test strip slot, a modulelower cover 246, afirst circuit board 253 and asecond circuit board 256, as shown in fig. 3A, thetest strip slot 243 and the moduleupper cover 240 are integrally formed, and a test stripupper bearing end 241 and a test strip lower bearingend 244 are defined in thetest strip slot 243, which define a height for accommodating atest strip 220, so that the height for inserting thetest strip 220 can be determined when thetest strip 220 is ejected out of the moduleupper cover 240, that is, the insertion height of thetest strip 220 is controlled by a single object, and the height defines a test strip slot height by the two bearing ends, the test strip slot height range H1 can be defined as a test strip thickness plus a proper gap, as shown in fig. 3A, when the thickness of the test piece is 1.0mm, the gap between the lower support end and the bottom surface of the test piece is set to be 0.05-0.5 mm, so the height range H1 of the proper test piece slot is about 1.05-1.5 mm.

Theoperation slot 245 of theupper module cover 240 has anoperation hole 242, the operation hole contains a first operation stroke component, the first operation stroke component contains the startingcomponent 250 and theblocking component 260, thelower module cover 246 contains a second operation stroke component, wherein the second operation stroke component contains aconductive component 270, anelastic component 280 and agrounding component 290, theconductive component 270, theelastic component 280 and thegrounding component 290 are arranged between the first operation row component and the second operation row component, the bottom of the lower module cover 246 (or the upper module cover 240) is provided with afirst circuit board 253, and the outer side of theupper module cover 240 is provided with asecond circuit board 256. The firstconductive region 234 and the secondconductive region 235 are disposed on thefirst circuit board 253, the firstconductive region 234 is electrically connected to the secondconductive region 235, thesecond circuit board 256 is disposed with the thirdconductive region 236, the secondconductive region 235 of thefirst circuit board 253 is electrically connected to the thirdconductive region 236 of thesecond circuit board 256 by theconnector 230, and theconnector 230 is one of a Flexible Printed Circuit (FPC) or a conductive rubber connector, but is not limited thereto. Theconnector 230 shown in fig. 4A is a conductive rubber connector, while theconnector 230 shown in fig. 4B is a Flexible Printed Circuit (FPC), and the electronic signal Vs can be electrically connected to a ground terminal (not shown) of thefirst circuit board 253 all the way through a path formed by theconductive element 270 and thegrounding element 290, and if the electronic signal Vs is a voltage, the loop will form a current.

In the present embodiment, thegrounding sheet 290 is disposed between theupper module cover 240 and thelower module cover 246, so that the overall thickness of the teststrip reading module 210 can be reduced by about 2-3 mm compared to the prior art teststrip reading module 110 disclosed in fig. 1C, and the teststrip reading module 210 is lighter and thinner compared to the prior art test strip reading module by adjusting the stacking sequence between the components in the present embodiment. Theelastic member 280 used in the present invention is not limited to a spring, and other members capable of providing elastic force, such as a metal spring, a metal spring (metal dome), may be used. Theconductive element 270 may be a cylindrical or spherical element, but is not limited to other shapes, and may be made of metal, such as steel. The blockingmember 260 is an elastic member, which may be made of rubber or silicone. In thegrounding plate 290, a plurality of throughholes 294 are configured to match the operation holes 242 to accommodate a plurality of blockingmembers 260 to actuate therein. When thetest strip 220 is inserted, the blockingmembers 260 move up and down through the throughholes 294 according to the coding design of thehole 222 of thetest strip 220.

As shown in fig. 3A, when thetest strip 220 is not inserted into the teststrip reading module 210, theelastic element 280 abuts against theconductive element 270, theconductive element 270 is pushed upwards, and the short-circuit protrusion 270 contacts theground strip 290 in response to the pushing of theelastic element 280, so that the electronic signal Vs can be transmitted from theground strip 290 to the firstconductive region 234 on thefirst circuit board 253 through theelastic element 280, and then transmitted to the thirdconductive region 236 on thesecond circuit board 256 through theconnector 230 via the secondconductive region 235 on thefirst circuit board 253 to form a conductive loop for the processing circuit of thesecond circuit board 256 to read to analyze the electronic signal Vs, determine the code of the test strip and determine the type of the test strip inserted into the teststrip reading module 210. The electronic signal Vs is a ground signal, and may be a voltage-current signal.

If the electrical signal Vs is a voltage, the loop will form a current. As shown in theleft operation hole 242 of fig. 3A, after thetest strip 220 is inserted into the teststrip reading module 210, when theactuating element 250 corresponds to thehole 222 without theprotrusion 224, theactuating element 250 is not pressed, and theconductive element 270 still contacts with the ground strip to form a conductive state, which can be interpreted as a first encoding signal. As shown in theright operation hole 242 of fig. 3A, when the activatingelement 250 is pressed corresponding to theprotrusion 224 of thetest strip 220, the position of the activatingelement 250 in theoperation hole 242 presses the blockingelement 260 downward, so that theconductive element 270 and thegrounding strip 290 form an open circuit state, and the electronic signal Vs from the signal source 291 cannot be transmitted to the thirdconductive area 236 of thesecond circuit board 256, so that no loop is formed to form a current, and the electronic signal is interpreted as a second encoding signal by thesecond circuit board 256. In addition, the activation height H2 of theactivation element 250 pressed by theprotrusion 224 is about 0.4mm to 0.8mm, which means that the activation of the first operation stroke element and the second operation stroke element can be effectively performed. In other words, when thetest strip 220 is disposed above the teststrip reading module 210, the above-mentioned no-current state indicates that theprotrusion 224 exists in thehole 222, which can also be used for decoding the password of the hole on thetest strip 220.

Therefore, those skilled in the art can understand the principle of reading the password of the test strip reading device of the present invention. In another embodiment, the test strip hole 222 (where theprotrusion 224 exists is designed to be in a conductive state, and where theprotrusion 224 does not exist is designed to be in an open circuit state. by the configuration of the above embodiment, it can be interpreted or identified the code of a single hole on thetest strip 220 according to whether the electronic signal Vs from the signal source 291 forms a loop or not.

The present invention provides the following solution to the problem of blood or dust contamination which often occurs in handling the test strip reading module during use, but is not limited thereto. Please refer to fig. 3B, which is a partial cross-sectional view of a test strip inserted into teststrip reading module 210 according to a second embodiment of the present invention. Fig. 3B follows the same reference numerals as fig. 3A. Thebarrier element 260 of figure 3B differs from thebarrier element 260 of figure 3A in that theconductive element 270 is shaped to match thebarrier element 260 in response to different types ofbarrier elements 260.

Referring to another embodiment of fig. 3C, the configuration and operation principle of the components of each portion are substantially similar to those of the embodiment of fig. 3B, except that the shape of thebarrier component 260 is changed, and theactivation component 250 and theconductive component 270 are combined into an elongated cylindricalconductive component 450, theconductive component 450 has afirst end 452 for contacting thehole 222 of thetest strip 220 and asecond end 454 for abutting against theelastic component 280, theconductive component 450 has afirst groove wall 457 closer to thefirst end 452 and asecond groove wall 458 opposite to thefirst groove wall 457, and the space between thefirst groove wall 457 and thesecond groove wall 458 is aside groove 456.

As shown in theleft operation hole 242 of fig. 3C, when thetest strip 220 is inserted into thetest strip slot 243 defined between theupper support end 241 and thelower support end 244 of the test strip and theconductive element 450 does not include theprotrusion 224 corresponding to thehole 222 of thetest strip 220, theconductive element 450 is not pressed, so that thesecond groove wall 458 of the short-circuit protrusion 272 of theconductive element 450 still contacts thegrounding plate 290, and therefore the electronic signal Vs forms a conductive state and forms a loop through thegrounding plate 290 and theelastic element 280 and the firstconductive region 234 of thefirst circuit board 253, and can be read as the first encoding signal. As shown in theright operation hole 242 of fig. 3C, when theconductive element 450 is pressed corresponding to theprotrusion 224 of thetest strip 220, the position of theconductive element 450 in theoperation hole 242 moves downward, so that the second groove wall 358 of the short-circuit protrusion 272 of theconductive element 450 is separated from thegrounding plate 290, and the electronic signal Vs from the signal source 291 and the firstconductive region 234 of thefirst circuit board 253 form an open circuit state.

As shown in fig. 3C, the blockingmember 360 of eachoperation hole 242 operates independently, so that the operation of the blockingmembers 360 of the other operation holes 242 is not interfered. Sinceisolation element 360 is preferably made of an elastic material, it can deform along with the up-and-down movement ofconductive element 450, and thus maintains a matching state withfirst trench wall 457. However, since thegrounding strip 290 is in an open circuit state with the firstconductive area 234 of thefirst circuit board 253, the electronic signal Vs from the signal source 291 cannot pass through the secondconductive areas 235 from the firstconductive area 234 of thefirst circuit board 253 and then is transmitted to the thirdconductive area 236 of thesecond circuit board 256 by theconnector 230, and thus no loop is formed to form a current, which is interpreted as a second encoding signal.

When thetest strip 220 is disposed above the teststrip reading module 210, thehole 222 is in a non-current state without theprotrusion 224. Therefore, those skilled in the art can understand the principle of reading the password of the test strip reading device of the present invention, and through the configuration of the above embodiment, the current can be formed according to the electronic signal Vs from the signal source 291, so as to interpret or identify the code of the single hole on thetest strip 220. Take two-bit encoding as an example, where one encoding state represents 0 and the other encoding state represents 1; and vice versa.

Referring to fig. 4A, in an embodiment of using theconductive rubber connector 231 as theconnector 230, theconductive rubber connector 231 includes a fourthconductive area 238 formed by a plurality of electrical contacts electrically isolated from each other, a thirdelectrical contact 2381 at a first end of the fourthconductive area 238 is matched with and contacts the thirdconductive area 236 on thesecond circuit board 256, a fourthelectrical contact 2382 at a second end of the fourthconductive area 238 is matched with and contacts the secondconductive area 235 on thefirst circuit board 253, and the secondconductive area 235 is electrically connected to the firstconductive area 234, such that the plurality of encoding signals correspondingly connected are transmitted from the firstconductive area 234 to the thirdconductive area 236 through the secondconductive area 235 and the fourthconductive area 238. The secondelectrical contact 2361 of the thirdconductive region 236 has the same area and shape as the firstelectrical contact 2351 of the secondconductive region 235. Each of the thirdconductive regions 236 is mated with at least 2 thirdelectrical contacts 2381 at a first end of the fourthconductive region 238, and each of the secondconductive regions 235 is mated with at least 2 fourthelectrical contacts 2382 at a second end of the fourthconductive region 238.

Referring to fig. 4B, in an embodiment of using theflexible circuit board 232 as theconnector 230, theflexible circuit board 232 includes a fourthconductive region 238, a first end of the fourthconductive region 238 is electrically connected to the thirdconductive region 236 of thesecond circuit board 256 in the connection socket, a second end of the fourthconductive region 238 is electrically connected to the secondconductive region 235 of thefirst circuit board 253, and the secondconductive region 235 is matched with and electrically connected to the firstconductive region 234, such that each of the plurality of encoding signals corresponding to the connection is transmitted from the firstconductive region 234 to the thirdconductive region 236 through the secondconductive region 235 and the fourthconductive region 238. Because theflexible circuit board 232 may sag at the bending portion due to the length relationship thereof, so that theflexible circuit board 232 interferes with the components below theflexible circuit board 232, a thin metal sheet is additionally installed on the lower edge of theflexible circuit board 232 to support theflexible circuit board 232, thereby avoiding the above-mentioned problems.

To solve the problems of the blocking assembly in the past and the blood contamination caused by the careless blood entering the inside of the physiological parameter measuring device, the present invention provides a solution as follows, but is not limited thereto.

As shown in fig. 3A, after the test strip is inserted into thetest strip slot 243, the activatingelement 250 moves up and down according to the code of thehole 222 on thetest strip 220, and pushes the blockingelement 260 below while moving, and the blocking element further pushes theconductive element 270, thereby reading the code on thetest strip 220, wherein the blockingelement 260 is an elastic element, which can be made of rubber or silicone rubber, so as to serve as an integrated rubber film for supporting a plurality of activatingelements 250. In addition, the blockingmember 260 is deformed when the actuatingmember 250 is actuated downward, so that an additional pressure difference is required when the actuatingmember 250 is pressed downward, and on the other hand, when external contaminants enter the reading module through theoperation hole 242, the contaminants are collected on the surface of the blockingmember 260, and the contaminants are prevented from flowing to the circuit components below.

In another solution proposed by the present invention, as shown in fig. 3B, after the test strip is inserted into thetest strip slot 243, theactuating element 250 moves up and down according to the code of thehole 222 on the test strip, and pushes the blockingelement 260 below while moving, and the blocking element further pushes theconductive element 270, so as to read the code on the test strip, wherein the blocking element includes afirst blocking element 261 in a cantilever shape and asecond blocking element 263 parallel to the side wall, so that each actuating element can operate independently without being affected by the actuation in theadjacent operation hole 242, and thus the code reading error occurs. In addition, thefirst blocking part 261 is deformed when the startingcomponent 250 moves downwards, so that the startingcomponent 250 needs an extra pressure difference when being pressed downwards, theconductive component 270 linked below is enabled to move more accurately, and the purpose of accurate coding is achieved.

Another solution proposed in the present invention is shown in fig. 3C, after thetest strip 220 is inserted, the blockingelement 360 deforms along with the up-and-down movement of theconductive element 450, and the blockingelement 360 includes afirst blocking element 361 and asecond blocking element 363, so that the respectiveconductive elements 450 can operate independently, and thus, the situation of erroneous code reading caused by mistakenly pressing the adjacent conductive elements when the blocking elements are shared does not occur. Thefirst barrier 361 makes thebarrier assembly 360 require additional pressure difference in the process of being extruded, so that thefirst barrier 361 is deformed, the actuation of the linkedconductive assembly 450 can be more accurate, and the accuracy of code reading can be improved.

As shown in fig. 3C, the modifiedbarrier assembly 360 is provided with acontaminant trap 362, thecontaminant trap 362 is formed between afirst barrier 361 and asecond barrier 363, thesecond barrier 363 is adjacent to and parallel to thefirst sidewall 345 of the aperture, and thecontaminant trap 362 is matched with theside groove 456. As shown in fig. 3C, thecontaminant trap 362 is shaped like a pocket groove. When the contaminant P from the test strip or the air inadvertently enters the test strip reading module 310, the contaminant P is confined in thecontaminant collecting portion 362 and will not enter the lower layer of the module to affect the conductive operation.

In comparison with thebarrier element 260 of fig. 3B, thebarrier element 360 of fig. 3C has a thickness and width of thefirst barrier 361 of thebarrier element 360 that are increased and narrower than thefirst barrier 261 of fig. 3B, so that the barrier element is stressed more intensively, and thebarrier element 360 forms a respective sleeve structure, so that during the process of being squeezed by the respective sleeve, the linkedconductive elements 450 can be actuated more precisely without being affected by other adjacentconductive elements 450, and thebarrier element 360 also includes acontaminant collecting portion 362, such as a U-shaped groove with a cross-section like a pocket shown in fig. 3C.
