Description

Analyte measurement module

The present invention relates to a test strip code reading apparatus, and more particularly to a test strip code reading apparatus having an elastic element for reading code.

The device for measuring physiological parameters (such as blood glucose concentration, cholesterol value, uric acid concentration, or pH value) can be sampled through the sampled sample to facilitate measurement under preset device conditions. Some analyte measuring devices can read different types of test pieces. In order to allow the analyte measuring device to increase or confirm the type of the test piece, or to achieve the anti-counterfeiting effect, a coding area can be made in a certain part of the test piece. For example, a hole of different depth is formed in a certain part of the test piece, and the analyte measuring device decodes the hole before reading the sample in the test piece to identify the type of the test piece and assist in reading the sample piece. The module selects the appropriate test configuration and can also have the function of anti-counterfeiting.

Such modules that utilize mechanical read coding also have some problems that are actually applied to the assembly of the instrument. For example, the combination of multiple components makes the control of dimensional tolerances difficult. As shown in FIG. 1 , the upper cover 101 of the conventional analyte measuring device housing already includes the upper structure 104 of the test strip slot during molding, and only the circuit board on which the test strip reading module 100 is disposed is required. The components such as the 103 and the back cover 102 are assembled one by one, and the upper cover 101 and the module body 140 together form a test strip slot space. However, this type of assembly is easily affected by the tolerances of the analyte measuring device housing and the reading module for injection molding, which often requires rework to adjust the height difference of the bearing surface of the test piece after assembly, because the test piece cannot be accurately discriminated. A measurement error caused by the encoding occurs.

On the other hand, the test piece measured by the test strip reading module has a sample of the sample, which is being tested. During the insertion of the slice reading module and the detection process, if the sample sample accidentally enters the inside of the analyte measuring device or the physiological parameter measuring device, the sample reading module may contaminate the sample sample and affect the test piece. The function of reading the electronic components in the module causes inaccurate detection, so it is urgent to provide an improvement method to solve the contamination problem of the sample sample.

In addition, when the test strip reading module 100 is to be applied to a handheld device such as a mobile phone or a personal digital assistant (PDA) to provide an immediate and convenient measurement by the user, the test strip reading module of the prior art. The appearance and height of the 100 obviously cannot match the characteristics of the handheld device that emphasizes lightness and shortness. Therefore, the present invention provides a modular thin test strip reading device that satisfies the functions of the test strip reading module when applied to the handheld device and the needs of the shape of the handheld device mechanism.

In order to overcome the problems of the conventional mechanical code reading module, in particular, it is necessary to take into consideration the correctness of the interpretation, the prevention of pollution and the improvement of assembly convenience. In order to achieve the object of the present invention, the present invention provides a test strip reading device comprising a module upper cover body, at least one test piece bearing end and a plurality of operation holes, wherein the plurality of operation holes can be placed into the plurality of first operation strokes a circuit board having a plurality of perforations and a plurality of operation holes for moving between the plurality of first operation stroke assemblies between each of the plurality of operation holes and each of the plurality of perforations, wherein the plurality of perforations at the bottom of the circuit board are provided a plurality of conductive regions; and a module lower cover body provided with a plurality of second operation stroke assemblies, wherein the contact and separation states of the plurality of second operation stroke assemblies and the conductive regions determine a read signal.

Please refer to FIG. 2C , which is a partial cross-sectional view of the test strip insertion test module reading module 210 according to the first embodiment of the present invention, wherein the test strip reading module 210 of the present invention includes a test strip slot. The module upper cover body 240, a circuit board 253, and a module lower cover body 246.

As shown in FIG. 2C, the test strip slot 243 is integrally formed with the module upper cover body 240, and the test piece upper end 241 and the test piece lower bearing end 244 are defined in the test strip slot 243, and the two bearers are supported. The height defines a height to accommodate the test piece 220, so that the height at which the test piece 220 is inserted can be determined when the module cover body 240 is ejected, that is, the test piece 220 is inserted into the height control through a single object, and the height is supported by the height. The end defines a test piece slot height, and the test piece slot height range 226 can be defined as a test piece thickness plus a suitable gap, as shown in FIG. 2C, when the test piece thickness is 1.0 mm, the lower bearing end The gap with the bottom surface of the test piece is set to 0.05~0.5mm, so the appropriate test piece slot height The range 226 is approximately 1.05 mm to 1.5 mm.

The module upper cover 240 includes a first operational stroke assembly, and the first operational stroke assembly includes an activation element 250, a barrier element 260, and an operation aperture 242 that can receive the activation element 250.

The circuit board 253 is provided with a conductive region 292 electrically connected to the signal source 291 for emitting the electronic signal Vs.

In the embodiment, the circuit board 253 is disposed at a position between the module upper cover 240 and the module lower cover 246, so that the overall thickness of the test strip reading module 210 is formed by the transmission assembly of FIG. The test piece reading module of 11~12mm can reduce the thickness of the module by about 2~3mm. In this embodiment, by adjusting the stacking order between components, the test piece reading module 210 is compared with the prior art. The test strip reading module is lighter and thinner. The barrier element 260, which is disposed in each of the operation holes 242, operates independently, and thus does not interfere with the operation of the barrier element 260 disposed adjacent or other operation holes 242.

The elastic member 280 used in the present invention is not limited to a spring, and other elastic-providing members such as a metal dome and a metal dome are applicable. The conductive element 270 can be a cylindrical or spherical element, but is not limited to other shapes. The material can be a metal material such as steel. The barrier element 260 is an elastic component and can be made of rubber or silicone. On the circuit board 253, a plurality of through holes 251 are arranged to match the operation holes 242 to accommodate a plurality of blocking elements 260, and a plurality of conductive areas are disposed on the circuit board 253 with respect to the periphery of the plurality of through holes 251. 292. When the test strip 220 is inserted, the plurality of barrier elements 260 move up and down through the plurality of perforations 251 according to the coding design of the holes 222 of the test strip 220.

When the test strip 220 is not inserted into the test strip reading module 210, the elastic element 280 bears against the lower end 254 of the conductive element 270, pushing the conductive element 270 upward, and a top surface 258 of the short-circuiting protrusion 272 is configured to respond to the elastic element 280. Pushing to contact the conductive region 292 of the circuit board 253, Therefore, the electronic signal Vs can pass through the conductive region 292 of the circuit board 253 to the conductive member 270 and form a conductive state with the ground member 290 through the elastic member 280, and the formed path is electrically connected to the ground end, and the 2D picture is the test piece reading. The bottom view of the module shows the position of the conductive area 292 in the test strip reading module 210, and the second E is a schematic diagram of adding the lower cover body 246 to the test strip reading module shown in the second drawing. The module lower cover 246 is fixed to the circuit board 253 by screws 296.

If the electronic signal Vs is a voltage, the above loop will form a current. In another embodiment, the signal source 291 that emits the electronic signal Vs may be disposed on the circuit board 253. As shown in the left operation hole 242 of FIG. 2C, after the test piece 220 is inserted into the test piece reading module 210, when the starting element 250 corresponds to the hole 222 without the convex portion 224, the starting element 250 is not pressed, and is electrically conductive. The component 270 is still in contact with the conductive region 292 of the circuit board 253 to form a conductive state, which can be interpreted as a first encoded signal.

As shown in the right operation hole 242 of FIG. 2C, when the activation member 250 is pressed corresponding to the convex portion 224 of the test piece 220, the position of the activation member 250 in the operation hole 242 presses the barrier member 260 downward, thereby making The top surface 258 of the short-circuit protrusion 272 of the conductive element 270 and the conductive region 292 of the circuit board 253 form a disconnected state, and the electronic signal Vs from the signal source 291 cannot be transmitted to the ground, so that no loop is formed to form a current, and it is interpreted as The second coded signal. In addition, the starting height 225 of the actuating element 250 that is squeezed by the raised portion 224 is between about 0.4 mm and 0.8 mm, which facilitates the actuation of the first operational stroke assembly and the second operational stroke assembly. In other words, when the test strip 220 is disposed above the test strip reading module 210, the current-free state means that the convex portion 224 is present in the hole 222, which can also be used as a test strip. Interpretation of the hole password on 220.

Therefore, those skilled in the art can understand the principle of password reading of the test strip reading device of the present invention. In another embodiment, the portion of the test strip hole 222 where the convex portion 224 is present is designed to be electrically conductive. Where the raised portion 224 is not present, it is designed to be broken. road. Through the configuration of the above specific embodiment, the current can be formed according to the electronic signal Vs from the signal source 291, and the code of the single hole on the test strip 220 can be interpreted or recognized. Taking a two-bit encoding as an example, one of the encoding states represents 0, and the other encoding state represents 1; vice versa.

In this embodiment, referring to FIG. 2B, the test strip reading module 210 further includes an electrical contact portion 255 electrically connected to the electrodes on the test strip 220, and the electrical contact portion 255 is electrically contacted by two contacts. Point formation. When the test strip 220 is inserted into the test strip slot 243, the working electrode and the counter electrode on the test strip 220 are in electrical contact with the two contacts, wherein the material of the electric contact portion is preferably made of gold material, and the corresponding electrode material of the test strip is compared. Good for gold materials, such as the Righttest® Blood test strip, allows the current produced by the test strip to have better stability and conductivity. The test piece 220 is not limited to the design of the concave shape, and may be other design choices, such as one of a bump, a saw tooth, a row of teeth, a slit, a groove and a through hole, and the test piece is read with the test piece. Group 210 performs a combination of actions.

Please refer to FIG. 2F, which is a partial cross-sectional view of the test strip insertion test strip reading module 210 in the second embodiment of the present invention. The 2Fth diagram is a partial improvement based on the 2Cth diagram, and the 2Fth diagram is the same as the 2C diagram. The difference between the 2F map and the 2C map is that the second embodiment of the 2F can further reduce the height of the reading module 210. The grounding component 290 and the conductive region 292 are disposed on the circuit board 253. Therefore, the grounding component 290 originally disposed at the bottom of the module lower cover 246 can be removed, so that the height of the test strip reading module 210 is reduced, and the elastic force is reduced. Element 280 can be formed of any resilient material that is electrically conductive or non-conductive.

As described above, on the circuit board 253, a plurality of through holes 251 are arranged to match the operation holes 242 to accommodate the corresponding plurality of blocking elements 260 to move up and down in the plurality of through holes 251, and the original grounding element 290 is set to be set. The conducting component 293 on the circuit board 253 completes the task of the grounding component 290. The conducting component 293 is disposed around the through hole 251 with respect to the first side of the conductive component 270, and the conductive region 292 is disposed on the circuit board 253 with the through hole 251. around And relative to the second side of the perforations 251 of each of the conductive elements 270. Therefore, each of the conductive elements 293 and the conductive regions 292 are respectively disposed around the through holes 251 of the circuit board 253 and are electrically isolated from opposite sides of the through holes 251 of the conductive member 270, and the effect thereof is the same as that in the first embodiment. The grounding element 290 and the conductive region 292 are the same. In the present embodiment, when the test strip 220 is not inserted, the elastic member 280 bears against the lower end 254 of the conductive member 270, pushing the conductive member 270 upward, so that the conductive region 292 on the circuit board 253 is in contact with the conductive member 293. A short circuit is formed, so that the electrical signal Vs contacts the conductive region 292 of the circuit board 253 and the conductive member 293 through the conductive member 270 to form a conductive state and form a loop.

As shown in the left operating hole 242 of the 2F, when the test piece 220 is inserted and the starting element 250 corresponds to the test piece hole 222 without the convex portion 224, the starting element 250 is not pressed, so that the conductive element 270 remains tested. When the sheet 220 is not inserted, the conductive region 292 is in contact with the conductive element 293 to form a conductive state, which can be interpreted as a first encoded signal; as shown in the 2F right operating hole 242, when the starting component 250 corresponds to the bump of the test strip 220 When the portion 224 is squeezed, the position of the activation member 250 in the operation hole 242 presses the barrier member 260 downward, so that a top surface 258 of the conductive member 270 is separated from the circuit board 253, and the conductive region 292 on the circuit board 253 is electrically connected. The element 293 is in an open state, so that the electronic signal Vs and the conducting element 293 form a non-conducting state and can be interpreted as a second encoded signal. Each of the conductive elements 293 is electrically connected to a detecting circuit (not shown) on the circuit board 253, such that each of the conductive elements 293 is in contact with the conductive region 292 to form a conductive state, and is sent to the detecting circuit to interpret the foregoing encoding. Signal.

The present invention proposes the following solutions in dealing with the problem of blood or dust contamination which often occurs in the use of the test strip reading module, but is not limited thereto.

As shown in FIG. 2C, when the test piece is inserted into the test strip slot 243, the actuating element 250 will move up and down in response to the coding of the hole 222 in the test piece, and will move to the lower barrier element 260 while moving, and the blocking element is again The conductive element 270 is further extruded, thereby interpreting the code on the test strip, wherein the barrier element comprises a first barrier 261 of a cantilever type and a second barrier parallel to the side wall 263, so that each of the activation elements can operate independently without being affected by the actuation in the adjacent operation holes 242, and there is a case of erroneous reading. In addition, the first barrier 261 is deformed when the starting element 250 is actuated downward, so that the starting element 250 requires an additional pressure difference when the pressing element is pressed, so that the lower conductive element 270 is more accurately operated to achieve accurate encoding, and the other On the other hand, when external contaminants enter the reading module via the operating hole 242, they are collected in the two V-shaped contaminant collecting portions 262 under the starting element without directly affecting the conductive operation mode of the lower layer.

Referring to FIG. 3A, for another embodiment, the component arrangement and actuation principle of each portion is substantially similar to the embodiment of FIG. 2C, with the difference that the elongated component 150 is used in place of the activation component 150, the conductive component 350 has a first end 352 for contacting the aperture 322 of the test strip 320, and a second end 354 for abutting the resilient member 380, the conductive element 350 having a first slot wall 357 closer to the first end 352 and relative to the first The second groove wall 358 of the groove wall 357. The space between the first groove wall 357 and the second groove wall 358 is a side groove 356.

As shown in the left operation hole 342 of FIG. 3A, when the test piece 320 is inserted into the test piece slot 343 defined between the bearing end 341 and the test piece lower bearing end 344, and the conductive member 350 corresponds to the test piece. When the hole 322 of the 320 does not contain the protrusion 324, the conductive element 350 is not pressed, so that the second groove wall 358 of the conductive element 350 is still in contact with the conductive area 392 on the circuit board 353, so the electronic signal Vs is transmitted through the conductive area 392. Forming a conductive state with the grounding member 390 and forming a loop, which can be interpreted as a first encoded signal; as shown in the right operating hole 342 of FIG. 3A, when the conductive member 350 is pressed against the raised portion 324 of the test strip 320, it is squeezed. At this time, the position of the conductive member 350 in the operation hole 342 moves downward, thereby causing the second groove wall 358 of the conductive member 350 to be separated from the conductive portion 392, so that the electronic signal Vs and the ground member 390 form an open state.

As shown in FIG. 3A, the barrier elements 360 disposed in each of the operation holes 342 operate independently, and thus do not interfere with the operation of the barrier elements 360 in which the other operation holes 342 are disposed. Since the blocking element 360 is preferably an elastic material, it can follow the upper and lower sides of the conductive element 350. It moves and deforms, so it maintains a matching state with the first groove wall 357. However, since the electronic signal Vs from the signal source 391 cannot be transmitted to the ground terminal when the conductive element 350 and the ground element 390 are in an open state at this time, the loop is not formed to form a current, and is interpreted as the second encoded signal.

When the test piece 320 is disposed above the test piece reading module 310, the hole 322 is in a state of no current when the convex portion 324 is not present. Therefore, those skilled in the art can understand the principle of password reading of the test strip reading device of the present invention. According to the configuration of the above embodiment, the current can be interpreted according to the electronic signal Vs from the signal source 391. Or identify the code of a single hole on the test strip 320. Taking a two-bit encoding as an example, one of the encoding states represents 0, and the other encoding state represents 1; vice versa.

Please refer to FIG. 3B, which is a partial cross-sectional view of the test strip insertion test strip reading module 310 in the fourth embodiment of the present invention. Fig. 3B is a partial improvement based on Fig. 3A, and Fig. 3B is the same as that of Fig. 3A. The difference between FIG. 3B and FIG. 3A is that the grounding element and the conductive region 392 are disposed on the circuit board 353 at the same time, so that the grounding element 390 originally disposed at the bottom of the test strip reading module 310 can be It is removed to further reduce the height of the test strip reading module 310, and the elastic element 380 can be formed of any resilient material that is electrically conductive or non-conductive. Similar to the 2F, the original grounding element 390 is changed to the conducting element 393, disposed on the circuit board 353 around the through hole 351 with respect to the first side of the shorting protrusion 372 of each conductive element 350, and the conductive region 392 is formed on the circuit board 353. The upper perforation 351 is around the second side of the shorting protrusion 372. Therefore, each of the conductive elements 393 and the conductive regions 392 are respectively disposed around the through holes 351 on the circuit board 353 to be electrically isolated from the two sides of the short-circuit protrusions 372.

In the fourth embodiment, when the test strip 320 is not inserted, the second end 354 of the elastic element 380 pushes the conductive element 350 upward, so that the conductive area 392 is in contact with the conductive element 393 to form a short circuit. Therefore, the electronic signal Vs transmits the conductive region through the conductive member 350 392 is in contact with the conductive element 393 to form a conductive state and form a loop. As shown in the left operation hole 342 of FIG. 3B, when the test piece is inserted and the conductive member 350 corresponds to the test piece hole 322 which does not include the convex portion 324, the conductive member 350 is not pressed, so that the conductive member 350 remains tested. When the sheet 320 is not inserted, the conductive region 392 is in contact with the conductive member 393 to form a conductive state, which can be interpreted as a first encoded signal; as shown in the right operating hole 342 of FIG. 3B, when the conductive member 350 corresponds to the bump of the test strip When the portion 324 is squeezed, the position of the conductive member 350 in the operating hole 322 presses the blocking member 360 downward, so that the second groove wall 358 of the conductive member 350 is separated from the conductive portion 392 and the conductive member 393 to form an open state. The electronic signal Vs and the conducting element 393 form a non-conducting state and can be interpreted as a second encoded signal. Each of the conductive elements 393 is electrically connected to a detecting circuit (not shown) on the circuit board 353, so that each of the conductive elements 393 is in contact with the conductive region 392 to form a conductive state, and is sent to the detecting circuit to read the foregoing. Coded signal.

In order to solve the problems caused by the past barrier elements and the blood pollution caused by the inadvertent entry of blood into the physiological parameter measuring device, the solution proposed by the present invention is as follows, but is not limited thereto.

As shown in FIG. 3A, after the test strip 320 is inserted, the blocking element 360 is deformed as the conductive element 350 moves up and down. The blocking element 360 includes a first barrier 361 and a second barrier 363 to make the respective conductive elements. The operation of the 350 can be operated independently, so that the common blocking element does not accidentally press into the adjacent conductive element to cause an erroneous reading. Moreover, the first barrier 361 causes the barrier element 360 to have an additional pressure difference during the process of being squeezed, so that the first barrier 361 is deformed, so that the interlocking conductive component 350 can be more accurate in motion, thereby improving the accuracy of reading.
