New description: [New technical field] The technology of this creation provides a single biochemical test piece, especially the test piece structure used to measure the blood sugar level in blood. [Previous technology] According to the advancement of technology, many of the early basic tests that can only be carried out in hospitals have become home-based instruments, and even have personal instruments that can be carried around, so that patients can always The detection action can be carried out by itself. In recent years, the proportion of elderly people suffering from diabetes has increased significantly. Therefore, there are many instruments on the market that can detect blood sugar levels by themselves, and the detection method only needs to contaminate the so-called biochemical test strips. Inserted into the blood glucose meter, the blood sugar level in the blood can be detected. As shown in the first figure and the second figure, it is a biochemical test piece 1, which is mainly printed with a second conductive film on a substrate ii. 11. A reaction zone worker 2 is disposed at one end of the second conductive film 11i, and the reaction zone 112 is simultaneously contacted with the two conductive films 1 1 1. Further, an insulating layer is disposed on the second conductive film 11 1 . 2, the insulating layer 12 and a recess 120 on the side of the reaction zone 112, the recess 120 is covered with a protective film 13, and the protective film 13 is provided with a ventilation Hole 1 3 When using biochemical test strip 1, the blood is mainly dripped into the reaction zone 1 1 2 of the groove work 20, and the blood is covered by the capillary phenomenon. 3 M378383 reaction zones 1 i 2 ' Finally biochemical The test piece is inserted into the blood stasis detecting instrument to cause the blood to react in the reaction zone 112, and electrochemical changes are made, and the blood glucose detecting instrument receives the change of the two conductive film iii to detect the blood sugar in the gold liquid. Since the biochemical test piece 1 is a single-use product, a new biochemical test piece 1 must be used for each test, but the biochemical test piece 1 may affect the reaction zone due to humidity in the air, excessive time of placement, or temperature. 2, and the resistance value of the conductive film 1 ii of each biochemical test piece 1 is slightly different, so the accuracy of the detected blood sugar level will also be affected. Therefore, how to eliminate the above problems is the technical difficulty point that the creators of the case want to solve. [New content] Therefore, in view of the above-mentioned shortcomings, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, this design was used to measure blood. A new patent for the structure of the test piece of blood sugar content. The main purpose of this creation is that the biochemical test strip is mainly composed of a matrix, a three-conducting membrane, an insulating layer and a protective film. Before the blood enters the reaction zone, the second detecting device is used to measure the conductive film. The resistance value is used as a reference value, and when the blood enters the reaction zone to generate a reaction, the resistance value of the two conductive films covered by the reaction zone is measured, and finally, the reference value and the resistance value after the reaction are calculated, and the M378383 is read. 'This is to increase the accuracy of the system and reduce the detection error value. The secondary purpose of this creation is: when the biochemical test strip is inserted into the external testing equipment, by correcting the design of the conductive film, it is possible to speculate that the amount of money entered in the reaction zone is sufficient to improve the accuracy of the biochemical test piece. The purpose. [Embodiment] The above-mentioned objects and effects are achieved, and the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present creation, and the features and functions are as follows. Please refer to the third, fourth, fifth, sixth, seventh and eighth figures, which are the three-dimensional appearance, the exploded view, the perspective view and the preferred embodiment of the creation. As is clear from the figure, the biochemical test strip 2 mainly comprises: a substrate 3; the second conductive film 3 1 ' is coated on the surface of the substrate 3, wherein the two conductive films 31 are in a conducting state' and the other is separately The conductive film 31 is disposed on the outermost side of the substrate 3; a reaction region 3 2 ' is coated on the surface of the substrate 3, and simultaneously covers one of the two conductive films 31, and a separate conductive film 3 1 ; An insulating layer 4 is disposed on the substrate 3 and covers the conductive 5 M378383 film 31 and the reaction zone 32, and an opening 4 1 ' is formed on the portion covering the reaction zone 32 by the opening 4 1 a protective film 5 is formed to cover the opening 4 1 of the insulating layer 4 and is provided with a through hole 5 1 and a slight distance between the protective film 5 and the reaction zone 32; When the biochemical test piece 2 is created, the blood sample is placed on the side of the opening 4 1 due to the protective film 5 and There is a slight distance between the reaction zones 32. Therefore, the blood sample can be sucked into the reaction zone 32 by the capillary action generated by the small distance, and the through hole 51 of the protective film 5 can increase the suction speed of the blood sample. After the blood sample is covered with the entire reaction zone 3 2, the biochemical test strip 2 can be inserted into the detecting device 6 from one end of the exposed conductive film 31, so that the detecting device 6 performs the detecting action on the biochemical test strip 2. Before the biochemical test strip 2 is inserted into the detecting device 6 and the blood is not inhaled, the detecting device 6 first energizes the two-conducting conductive film 31, and records the resistance value passed as the reference resistance value, and when the blood sample is inhaled After filling the entire reaction zone 3 2, the blood sample dissolves and reacts the reagent (or reactant) added in the reaction zone 32, and an electrochemical reaction change occurs, and a resistance is generated during the change process. And the detecting device 6 measures the resistance value of the two conductive films 31 covered by the reaction zone 32 at this time, and the electrical reaction changes due to the reaction zone 3 2 M378383 generate resistance, so finally The measured resistance is different from the resistance value of the reference value, and the detecting device 6 compares the received resistance value with the resistance value of the reference value as a basis for calculating the blood sugar content in the blood sample. The impedance value of the conductive film 3 1 of the biochemical test piece 2 may be different, and the reaction zone 32 may also affect the enzyme in the moon b due to the temperature susceptibility, the placement time or the temperature, so that the parent biochemical test piece 2 is detected. The result is inaccurate, because #, by comparing the resistance value of the reference value with the measured resistance value, to improve the accuracy of detecting blood glucose; In addition, 'users are collecting their own blood samples, possibly due to blood samples collected. If the amount is too small or the blood sample is inhaled into the reaction zone 32, the error of the detection data value is too large. Therefore, the purpose of providing the conductive film 31 in the two-conducting state is mainly to establish a reference resistance value to be inhaled as the reaction zone 32. After the blood is compared, the correct blood sugar content (concentration) is calculated by the error of the two. Further, the reaction zone 32 is covered with the two conductive films 31 at the same time, and if the blood sample is not diffused, The touched two conductive films 31, since the detecting device 6 is turned on and can not detect the resistor, the detection means 6 determines that insufficient blood sample without detecting operation, thereby to achieve avoid detection device 6 detects an invalid operation. However, the above description is only a preferred and feasible embodiment of the present invention, and thus does not limit the scope of the patent of the creation. Therefore, the equivalent structure of the 7 M378383 and the illustrated content is directly or indirectly. Those who apply to other related technical fields should all be included in the scope of the spirit of this creation and be combined with Chen Ming.
