An upper bearing end 241 and a lower bearing end 244 of the test piece are defined in the groove 243. The two bearing ends define a height to accommodate the test piece 220, so that the insertion height of the test piece 220 can be ejected into the module upper cover 240. It is determined at that time, that is, the height of the test strip 220 is controlled through a single object, and the height is defined by the two end ends of a test strip slot height. The test strip slot height range H1 can be defined as a test strip thickness plus The last suitable gap, as shown in Figure 3A, when the thickness of the test piece is 1.0mm, the gap between the lower bearing end and the bottom of the test piece is set to 0.05 ~ 0.5mm, so the appropriate test slot height range H1 is about 1.05 mm ~ 1.5mm.

The operation slot 245 of the module upper cover 240 has an operation hole 242.

A first conductive region 234 and a second conductive region 235 are disposed on the first circuit board 253. The first conductive region 234 is electrically connected to the second conductive region 235. A third conductive region 236 is disposed on the second circuit board 256. The first circuit The second conductive region 235 of the board 253 and the third conductive region 236 on the second circuit board 256 are electrically connected by a connector 230. The connector 230 is one of a flexible circuit board (FPC) or a conductive rubber connector. , But not limited to this. The connector 230 shown in FIG. 4A is a conductive rubber connector, and the connector 230 shown in FIG. 4B is a flexible circuit board (FPC), and the electronic signal Vs can pass through the conductive element 270 and the ground element 290 The formed path is electrically connected to the ground terminal (not shown) of the first circuit board 253 all the way. If the electronic signal Vs is a voltage, the above-mentioned circuit will form a current.

In this specific embodiment, the grounding piece 290 is disposed 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 compared with that of the prior art disclosed in FIG. 1C. The test strip reading module 110 can reduce the module thickness by about 2 ~ 3mm. In this specific embodiment, by adjusting the stacking order between the components, the test strip reading module 210 is compared with the conventional technology. The module is thinner and lighter. The elastic element 280 used in the present invention is not limited to a spring, and other elements capable of providing elastic force such as a metal dome and a metal dome can be applied. The conductive element 270 may be a cylindrical or spherical element, but is not limited to other shapes. The material may be a metal material, such as steel. The blocking element 260 is an elastic element, which can be made of rubber or silicon. A plurality of through holes 294 are arranged on the grounding plate 290 to match the operation holes 242 to accommodate the plurality of blocking elements 260 for operation therein. When the test strip 220 is inserted, the plurality of blocking elements 260 move up and down through the plurality of perforations 294 according to the coding design of the holes 222 of the test strip 220.

As shown in FIG. 3A, when the test strip 220 is not inserted into the test strip reading module 210, the elastic element 280 is pressed against the conductive element 270, and the conductive element 270 is pushed upward, and the short-circuited protrusion 270 is corresponding to the push of the elastic element 280. The electronic signal Vs can be transmitted from the ground plate 290 to the first conductive region 234 on the first circuit board 253 through the elastic element 280 and pass through the second conductive region 235 on the first circuit board 253. Then, it is transmitted to the third conductive region 236 on the second circuit board 256 via the connector 230 to form a conductive loop, which can be read by the processing circuit of the second circuit board 256 to analyze the electronic signal Vs, determine the coding of the test strip and determine the insertion. Test strip type of the test strip reading module 210. The electronic signal Vs is a ground signal, and may also be a voltage current signal.

If the electronic signal Vs is a voltage, the above-mentioned circuit will form a current. As shown in the left operating hole 242 in FIG. 3A, after the test strip 220 is inserted into the test strip reading module 210, when the activation element 250 corresponds to the hole 222 without the protrusion 224, the activation element 250 is not squeezed and is conductive. The element 270 is still in contact with the ground plate to form a conductive state, and can be interpreted as a first coded signal. As shown in the right operation hole 242 in FIG. 3A, 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 blocking member 260 downward, so that The conductive element 270 and the ground plate 290 form an open circuit state, and the electronic signal Vs from the signal source 291 cannot be transmitted to the third conductive region 236 of the second circuit board 256. Therefore, if a loop is not formed to form a current, the second circuit board 256 Interpreted as a second coded signal. In addition, the starting height H2 of the starting element 250 being squeezed by the convex portion 224 is between about 0.4 mm and 0.8 mm, which helps the first and second operating stroke components to effectively perform their operations. In other words, when the test strip 220 is arranged above the test strip reading module 210, the above-mentioned no-current state means that there is a convex portion 224 in the hole 222, which can also be used for the test strip. Interpretation of the hole password on 220.

Therefore, persons with ordinary knowledge in the art can understand the password reading principle of the test strip reading device of the present invention. In another embodiment, the test piece hole 222 (where the convex portion 224 is present is designed to be conductive, and where the convex portion 224 is not present is designed to be open circuit. Through the configuration of the above specific embodiment, it may be Based on whether the electronic signal Vs from the signal source 291 constitutes a current or not, it can decode or identify the code of a single hole on the test strip 220. Take a two-bit code as an example, where one code state represents 0, and the other code The status represents 1; vice versa.

In dealing with the problem of blood or dust contamination that often occurs in the use of the test strip reading module, the present invention proposes the following solutions, but is not limited thereto. Please refer to FIG. 3B, which is a partial cross-sectional view of the test strip inserting test strip reading module 210 in the second embodiment of the present invention. FIG. 3B uses the same element symbols as those in FIG. 3A. The barrier element 260 in FIG. 3B is different from the barrier element 260 in FIG. 3A. In order to respond to different types of the barrier element 260, the shape of the conductive element 270 is adjusted so as to match the barrier element 260.

Please refer to another specific embodiment in FIG. 3C. The component configuration and operation principle of each part are basically similar to the embodiment in FIG. 3B. The difference is that the shape of the blocking element 260 is changed, and the activation element 250 and the conductive element 270 are combined into An elongated columnar conductive element 450 having a first end 452 for contacting the hole 222 of the test piece 220 and a second end 454 for abutting the elastic element 280. The conductive element 450 has a relatively close The first groove wall 457 of the first end 452 and the second groove wall 458 opposite to the first groove wall 457. The space between the first groove wall 457 and the second groove wall 458 is a side groove 456.

As shown in the left operating hole 242 of FIG. 3C, when the test piece 220 is inserted into the test piece slot 243 defined between the test piece end 241 and the test piece lower end 244 and the conductive element 450 corresponds to the test piece When the hole 222 of 220 does not include the protrusion 224, the conductive element 450 is not squeezed, so that the second groove wall 458 of the short-circuited protrusion 272 of the conductive element 450 is still in contact with the ground plate 290, so the electronic signal Vs passes through the ground plate 290 and The elastic element 280 and the first conductive region 234 of the first circuit board 253 form a conductive state and form a loop, and can be interpreted as a first coded signal. As shown in the right operation hole 242 in FIG. 3C, when the conductive element 450 is pressed corresponding to the protruding portion 224 of the test piece 220, the position of the conductive element 450 in the operation hole 242 moves downward, thereby making the conductive element 450 The second groove wall 358 of the short-circuiting protrusion 272 is detached from the ground piece 290, so that the electronic signal Vs from the signal source 291 and the first conductive region 234 of the first circuit board 253 form a disconnected state.

As shown in FIG. 3C, the blocking elements 360 disposed in each operation hole 242 operate independently, and therefore do not interfere with the operations of the blocking elements 360 disposed in other operation holes 242. Since the blocking member 360 is preferably made of an elastic material and can be deformed as the conductive member 450 moves up and down, it is maintained in a matched state with the first groove wall 457. However, since the ground plate 290 and the first conductive region 234 of the first circuit board 253 are disconnected at this time, the electronic signal Vs from the signal source 291 cannot pass through the first conductive region 234 on the first circuit board 253. Each of the second conductive regions 235 is then transmitted by the connector 230 to the third conductive region 236 of the second circuit board 256. Therefore, no loop is formed to form a current, and it is interpreted as a second coded signal.

When the test strip 220 is disposed above the test strip reading module 210, when there is no convex portion 224 in the hole 222, the current is in a non-current state. Therefore, people with ordinary knowledge in the field can understand the password reading principle of the test strip reading device of the present invention. Through the configuration of the above embodiments, the current can be interpreted based on the electronic signal Vs from the signal source 291 and can be interpreted. Or identify the code of a single hole on the test strip 220. Take two-bit encoding as an example, one of the encoding states represents 0, and the other encoding state represents 1; and vice versa.

Referring to FIG. 4A, an embodiment in which a conductive rubber connector 231 is used as the connector 230. The conductive rubber connector 231 includes a fourth conductive region 238, which is composed of a plurality of electrical contacts electrically isolated from each other.

In order to solve the problems caused by the barrier element in the past and the blood staining problem caused by blood entering the physiological parameter measuring device accidentally, a solution proposed by the present invention is as follows, but is not limited thereto.

As shown in FIG. 3A, after the test strip is inserted into the test slot 243, the starting element 250 will move up and down in response to the coding of the hole 222 on the test strip 220, and it will be squeezed to the lower blocking element 260 while moving, blocking The element further squeezes the conductive element 270 to interpret the code on the test piece 220. The blocking element 260 is an elastic element, which can be made of rubber or silicon rubber, so as to be an integrated rubber film carrying a plurality of starting elements 250. In addition, the blocking element 260 is deformed when the starting element 250 is moved downward, so that the starting element 250 requires an additional pressure difference when it is pushed down. On the other hand, when external contaminants enter the reading module through the operation hole 242, Will be collected on the surface of the barrier element 260 to prevent contaminants from flowing to the underlying circuit elements.

Another solution proposed by the present invention is shown in FIG. 3B. After the test piece is inserted into the test piece slot 243, the starting element 250 will move up and down due to the coding of the hole 222 on the test piece, and it will be squeezed to the same time as it moves. The lower barrier element 260, the barrier element further squeezes the conductive element 270, thereby interpreting the code on the test strip, wherein the barrier element includes a first barrier 261 in a cantilever shape and a second barrier 263 parallel to the side wall, so that each start The components can operate independently, and will not be affected by the actions in the adjacent operation holes 242, and there will be cases of incorrect code reading. In addition, the first barrier 261 will deform when the starting element 250 is actuated downward, so that the starting element 250 needs an additional pressure difference when it is pushed down, so that the conductive element 270 linked below can act more accurately and achieve the purpose of accurate coding. On the other hand, when external pollutants enter the reading module through the operation hole 242, they will be collected in two V-shaped pollutant collection portions 262 under the activation element, without directly affecting the conductive operation mode of the lower layer.

Another solution proposed by the present invention is shown in FIG. 3C. After the test piece 220 is inserted, the blocking element 360 will be deformed as the conductive element 450 moves up and down. The blocking element 360 includes a first barrier 361 and a second barrier. The barrier 363 allows the operations of the respective conductive elements 450 to operate independently, so that there is no case where a wrong barrier is pressed to a neighboring conductive element when the barrier element is shared, which causes a wrong reading of the code. In addition, the first barrier 361 causes the barrier element 360 to require an additional pressure difference during the process of being squeezed, deforms the first barrier 361, and makes the kinetic energy of the linked conductive element 450 more accurate, which can improve the accuracy of code reading.

As shown in FIG. 3C, the improved barrier element 360 is provided with a pollutant collecting device 362. The pollutant collecting portion 362 is formed between the first barrier 361 and the second barrier 363, and the second barrier 363 is close to and parallel to The first side wall 345 of the operation hole and the pollutant collecting part 362 are matched with the side groove 456. As shown in FIG. 3C, the cross section of the pollutant collecting portion 362 is a pocket-like groove. When the pollutant P from the test strip or the air accidentally enters the test strip reading module 310, the pollutant P will be confined in the pollutant collection part 362, and will not enter the lower layer of the module and affect the conductivity. Mode of action.

The barrier element 360 shown in FIG. 3C is compared with the barrier element 260 in FIG. 3B. The first barrier 361 of the barrier element 360 is thicker and narrower than the first barrier 261 in FIG. 3B. The element is more concentrated in force, and the blocking element 360 forms an individual sleeve structure. Therefore, during the extrusion of the individual sleeve, the kinetic energy of the connected conductive element 450 is more accurate, and it is not affected by other neighboring conductive elements 450. The blocking element 360 also includes a pollutant collecting portion 362. As shown in FIG. 3C, a U-shaped groove with a cross-section like a pocket is shown. The design of the blocking element of the present invention is not limited to other similar types.
