Taiwan application No. 103218437 discloses a multifunctional physiological measurement device, which has a plurality of test paper slots, selected from any combination of a blood glucose test paper slot, a uric acid test paper slot, a cholesterol test paper slot, a heme test slot and a triglyceride test paper slot, and can simultaneously detect a plurality of physiological signals, thereby forming a multifunctional detector, which can satisfy the requirement of one machine for multiple purposes. However, in order to install the plurality of reagent strip slots, the body is difficult to be miniaturized, and a user is likely to have a problem of mistakenly inserting a wrong slot, which is likely to cause a problem of obtaining wrong physiological data.

Therefore, taiwan patent application No. 107200586 discloses a physiological detection device and a test strip with an automatic determination function for calibrating parameters of the test strip, where the test strip includes a measurement electrode structure and a code electrode structure, and the test strip can be inserted into the physiological detection device to read the measurement electrode structure and the code electrode structure to obtain a measurement signal and a code, and obtain a calibration parameter according to the code, and the physiological detection device can obtain calibrated physiological data through an integrated operation of the calibration parameter and the measurement signal, and according to the design of the calibration parameter, after the test strip is inserted into a single slot, it can know which physiological data the test strip is to detect through the obtained code, and after the calibration parameter is calibrated, it can obtain correct physiological data.

Detailed Description

The present invention will now be described in further detail by way of examples, but it is to be understood that the following examples are illustrative only and are not to be construed as limiting the practice of the present invention.

The reaction region 30 is used for dropping a blood sample.

The first working electrode 40 is formed on the test strip 20 and electrically connected to the reaction region 30, and the second working electrode 50 is also formed on the test strip 20 and electrically connected to the reaction region 30. When the blood sample is dropped into the reaction region 30, an electrical signal is generated and can be measured between the first working electrode 40 and the second working electrode 50.

The determination electrode 60 is formed on the test strip 20, the determination electrode 60 includes a wiring circuit 61, in an embodiment, the wiring circuit 61 is directly electrically connected to the second working electrode 50, the wiring circuit 61 has a specified resistance, when the wiring circuit 61 is directly electrically connected to the second working electrode 50, the specified resistance approaches to 0, and the specified resistance of the wiring circuit 61 is determined according to the type of the physiological data to be measured, and the specified resistance is changed by changing the material of the specified resistance, including but not limited to changing the line width, line length, cross-sectional width, and the like of the wiring circuit 61.

The value of the specific resistance is related to the type of the physiological data, so that the physiological measurement apparatus 10 can know the type of the physiological data to be measured after knowing the value of the specific resistance through the determination electrode 60. When the physiological detection device 10 receives the electrical signal, the physiological detection device 10 can determine the measurement value of the physiological data since the physiological detection device 10 already knows the type of the physiological data.

Please refer to fig. 3 to 7, which are schematic diagrams of other embodiments of the wiring circuit 61 according to the first embodiment. The wiring circuit 61 in different embodiments has the specified resistance with different values. In one embodiment, the wiring circuit 61 may have a meander line 62, and the presence of the meander line 62 may increase the value of the specified resistance. The number of bending times of the repeated bending circuit 62 can determine the value of the designated resistance, and the resistance is higher as the number of bending times is larger, as shown in fig. 3 to 7, which are schematic diagrams of the repeated bending circuit 62 having different bending times and the designated resistance having different values, different types of physiological data can be correlated with each other.

Referring to fig. 8 to 10, which are schematic views of a second embodiment, the determining electrode 60 has two contacts 601, and the two contacts 601 are electrically connected to the wiring circuit 61 respectively, and similarly, the wiring circuit 61 may have the repeated bending circuit 62, as shown in fig. 9 to 10, the wiring circuit 61 in different embodiments of the repeated bending circuit 62 is used to obtain the assigned resistances with different values, and assign physiological data related to different types.

In addition, referring to fig. 11, in order to increase the wiring space, in an embodiment, the first working electrode 40 and the second working electrode 50 can be located on a first surface 201 of the test strip 20, and the determining electrode 60 is located on a second surface 202 of the test strip 20, and the first surface 201 and the second surface 202 are disposed back to back. Thus, the wiring circuit 61 has a sufficient space, and the upper limit value of the predetermined resistance is increased by increasing the wire length. In order to determine whether the insertion direction of the test strip 20 is correct, the first working electrode 40 and the second working electrode 50 on the first surface 201 and the determination electrode 60 on the second surface 202 are disposed at vertically offset positions, and through the offset design, the test strip 20 cannot be activated when the insertion direction is incorrect.

As mentioned above, the present invention has at least the following advantages over the prior art:

1. the judgment electrode is used to obtain the value of the specified resistance and judge the type of the physiological data to be measured, so as to meet the requirement of automatically judging and detecting the type of the physiological data.

2. The type of the physiological data to be detected is identified by judging the numerical value of the specified resistance, and the single-side design of the detection test piece can have enough identification quantity to meet the use requirement.

3. When the types of more physiological data need to be identified, the detection test piece can be designed in a double-sided mode, and the judgment electrode can be arranged on one side of the detection test piece, so that the detection test piece has sufficient wiring space, the numerical value of the specified resistance is increased, and the use requirement is met.
