Description

Technical Field

[0001] The invention relates to the technical field of blood sugar detection equipment, in particular to a plug-and-play enzyme electrode method biosensor blood sugar detection equipment. Background Art

[0002] Delete enzyme electrode biosensor is a composite sensor that combines a biologically active enzyme with an electrochemical electrode. The measurement process converts the enzyme reaction substrate to be measured into a product that responds to the electrochemical electrode through an enzymatic catalytic reaction. By measuring the response current of the electrochemical electrode, the concentration data of the enzyme reaction substrate is finally obtained.

[0003] The application of enzyme electrode biosensor in blood glucose detection can produce more accurate detection results. At the same time, since the activity of enzyme electrode changes very little in a short period of time (several minutes to tens of minutes), it can be used to detect blood glucose concentration in the human body. Specifically, when the blood sample is tested, the concentration of the blood sample is calculated based on the measured enzyme electrode response current and compared with the standard sample. The blood glucose test strip slot of existing blood glucose detection equipment is easily contaminated and cannot meet the requirements of continuous blood glucose detection.

[0004] For example, a continuous blood glucose detection device based on an enzyme electrode biosensor disclosed in China Invention Publication No. CN118130582A is provided with a sample insertion component, and the sample insertion component cooperates with an insertion component purification mechanism for purifying the sample insertion component to prevent impurities or contaminants from affecting the sensitivity of the sample insertion component, so that the present application can realize continuous detection of blood glucose concentration, avoid the problem of inaccurate blood glucose concentration detection due to continuous detection, and improve the detection efficiency. The setting of the covering insulating cover can avoid the loss or loss of the electrical signal between the output contact and the concentration detection electrode, thereby improving the accuracy of continuous detection.

[0005] During the detection process of the above-mentioned device, the sample test paper needs to be inserted into the working groove of the detection mechanism. During the detection process after the insertion, the sample test paper needs to ensure that the test paper is in close contact with the membrane of the sensor immobilized enzyme at all times. Therefore, in actual continuous use, after the test result of the previous test paper is calculated, it is necessary to wait for the disinfection mechanism of the application, that is, the ultraviolet sterilization lamp or air sterilizer in the disinfection seat for disinfection. This waiting process affects the detection efficiency, and because the disinfection seat is arranged adjacent to the membrane electrode of the sensor immobilized enzyme, the disinfection process of the application affects the subsequent reaction of glucose with oxidase or dehydrogenase. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a plug-and-play enzyme electrode method biosensor blood glucose detection device, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a plug-and-play enzyme electrode method biosensor blood glucose detection device, including a blood glucose detection device body, a detection port for detection is arranged in the middle of the upper end of the blood glucose detection device body, a protective shell for protection is arranged at one end of the detection port, a detection sensor for enzyme reaction is arranged in the protective shell, and a paper feeding module for transmitting the test strip is arranged inside the blood glucose detection device body. When the paper feeding module completes the transmission of the test strip, the highest area of ​​the conveyable position of the paper feeding module is located in the detection port; in the detection process of the traditional blood glucose detection device, the test strip is placed in the detection area, blood drips on the test strip, and the test strip is taken off after the detection is completed. This process often leads to the situation of blood contamination of the detection area mentioned in the background technology. In view of the above situation, a disinfection structure is added in the detection area. Although it has a disinfection effect, due to the risk of contact between the disinfection structure and the membrane electrode, the detection efficiency is reduced, the normal reaction of the enzyme electrode is affected, the detection accuracy is reduced, and the detection failure occurs;

[0008] In order to solve the above problems, the paper feeding module includes a paper feeding roller, a transfer roller and a winding roller symmetrically arranged inside the main body of the blood glucose testing device. A transfer roller located directly below the detection port is arranged between the winding roller and the paper feeding roller. The paper feeding roller, the transfer roller and the winding roller are connected by a transmission mechanism, and the transmission mechanism drives the three rollers to start rotating at the same time. A transmission port opened on the main body of the blood glucose testing device is arranged on one side of the paper feeding roller. A test paper card strip is placed on the transmission port during the detection process. The material of the test paper card strip can be aluminum, plastic, etc., because the test paper card strip is finally wound on the winding port. The winding roller needs to have a certain degree of ductility. The test paper card strip is arranged in an array with multiple groups of bayonet slots. The test paper body can be detachably placed in the bayonet slots. It should be noted that unlike traditional test paper, the test paper body is slightly bent due to the curved surface of the transfer roller when it is transmitted to the highest point. The test paper body is selected as Roche blood glucose test paper. The test paper is stuck in the bayonet slot. Finally, the test paper card strip is wound on the winding roller. This part of the test paper can be collected uniformly to avoid arbitrary discarding. The test paper card strip passes through the paper feed roller and the transfer roller in turn and the tail end is wound on the winding roller.

[0009] A further improvement of the technical solution of the present invention lies in that: mounting blocks are symmetrically arranged at the left and right ends of the transfer roller, the transfer roller is rotatably connected to the two groups of mounting blocks, and the bottoms of the two groups of mounting blocks are fixedly connected with electric control push rods, each of the electric control push rods is vertically fixed on the suspension, and in order to ensure that the mounting blocks are lifted under the action of the electric control push rods and the lifting does not deviate, guide rods passing through the mounting blocks are symmetrically arranged at both ends of the suspension, and the two mounting blocks are slidably connected to the corresponding guide rods respectively.

[0010] A further improvement of the technical solution of the present invention is that in order to avoid the reaction and contact between the disinfection component and the enzyme electrode, a disinfection component is arranged at the bottom of the suspension to separate the detection area and the disinfection area. The disinfection component includes a disinfection box installed at the bottom of the suspension, and an air disinfection component can be installed inside the disinfection box. The disinfection box is symmetrically provided with disinfection ducts along the axis of the transfer roller, and the other ends of the two disinfection ducts are fixedly installed with disinfection seats, and the middle parts of the two disinfection seats are provided with through-holes for the detection test paper body to pass through. An ultraviolet disinfection lamp can be installed on the upper part of the disinfection seat, and the ultraviolet disinfection lamp directly kills the detection surface of the detection test paper body. The bottom of the disinfection seat connected to the disinfection duct can transmit air disinfection gas. Therefore, it can be seen from the above that the separation of the disinfection area and the detection area largely avoids the adverse reaction between the disinfection operation and the enzyme electrode, and the disinfection area uses the through-hole to disinfect the transmitted test paper strip during the transmission process, which does not affect the detection efficiency while avoiding the reduction of the disinfection effect. While separating and disinfecting, the disinfection and detection operations are still integrated to ensure the detection efficiency.

[0011] A further improvement of the technical solution of the present invention is that: the front and rear ends of the transfer roller are rotatably installed with transmission pipes through fasteners, and the other ends of the two transmission pipes are connected to a liquid adding pipe, on which a vertical pipe for installing an electric control valve is arranged, and an electromagnet is sleeved on the outside of the liquid adding pipe, so the material of the liquid adding pipe needs to have good conductivity, and an electromagnetic coil is surrounded by the outside of the electromagnet, and the electromagnetic coil is electrically connected to the battery assembly through a wire, and a magnetorheological fluid is injected into the liquid adding pipe. It should be noted that when the electromagnetic coil is energized, the electromagnet generates magnetism, so after the magnetorheological fluid inside the liquid adding pipe senses the magnetic field and magnetism, the magnetorheological fluid changes from a low-viscosity fluid to a solid form with controllable yield strength. After the magnetorheological fluid becomes solid, magnetorheological fluid is gradually added through the vertical pipe, and the magnetorheological fluid eventually enters the transfer roller from a solid state.

[0012] A further improvement of the technical solution of the present invention is that: in the above, after the solid magnetorheological fluid enters the transfer roller, because the upper end of the transfer roller is arrayed with multiple groups of expansion holes, the solid magnetorheological fluid is released from the expansion holes. During this process, the electric control push rod starts to gradually drive the transfer roller to the highest point. After the transfer roller is at the highest position, the solid liquid abuts the test paper strip and the test paper body, and the test paper body is stably exposed at the detection port, thereby achieving the stability of the test paper body during blood sugar testing and ensuring the accuracy of the test results. The upper end of the transfer roller is hollow, and the lower end of the transfer roller is solid.

[0013] A further improvement of the technical solution of the present invention is that: a mounting seat is provided between the transfer roller and the winding roller, the mounting seat is fixedly installed inside the main body of the blood glucose testing equipment, and a cylinder is provided at the bottom of the mounting seat, and the other end of the cylinder is connected to the detection component. After the detection is completed, as the winding roller continues to wind, the detected test paper body is gradually transmitted to the winding roller. Then the detection component set in this process, specifically including a camera, transmits the color performance of the test paper to the display screen as a reference for the test results.

[0014] A further improvement of the technical solution of the present invention is that: in order to ensure the drying and further disinfection of the test strip body, a vertical plate is installed on the inner wall of one side of the blood glucose testing equipment body close to the transmission port, and an air insulation module is installed on the vertical plate. The air insulation module includes a round seat arranged in the middle of the vertical plate, and the round seat and the vertical plate are provided with openings matching the transmission port for test strip card transmission. A toothed disk is embedded on the outer wall of the round seat, and fan teeth are meshed and connected on four sides of the toothed disk. The four fan teeth are correspondingly keyed to a drive shaft, and each drive shaft is provided with a transmission wheel, and the four transmission wheels are all connected with a transmission belt.

[0015] A further improvement of the technical solution of the present invention is that an adjustment groove is provided on one side of the round seat close to the transfer roller, and an engaging seat is clamped in the adjustment groove. The engaging seat is rotatably connected to a heating tube whose other end is connected to a heating nozzle through a linkage seat. After the rotation of the drive shaft, the fan teeth on the four sides of the round seat begin to rotate due to the transmission of the transmission belt. Due to the engagement, the round seat rotates on itself, and the engaging seat clamped on the round seat follows the rotation. Finally, the heating nozzle connected to the heating tube begins to heat, dry and disinfect the transmitted test paper strip and the test paper body in all directions, thereby sterilizing the residual gas in the box while avoiding moisture on the test paper body, thereby avoiding failure of blood glucose detection.

[0016] A further improvement of the technical solution of the present invention is that: the two heating pipes are both connected to a hot air transmission pipe, and the hot air transmission pipe is connected to an external heating component.

[0017] Compared with the prior art, the invention has the following beneficial effects: by separating the disinfection area from the detection area, the adverse reaction between the disinfection operation and the enzyme electrode is avoided to a large extent, and the disinfection area is disinfected during the transmission process through the through-hole, which does not affect the detection efficiency and avoids the reduction of the disinfection effect. While the disinfection is separated, the disinfection and detection operations are still integrated to ensure the detection efficiency.

[0018] When the test paper body is transmitted to the highest point, it is slightly bent due to the arc surface of the transfer roller, and the test paper is stuck in the card slot. Finally, the test paper card strip is wound on the winding roller. This part of the test paper can be collected uniformly to avoid being discarded at will.

[0019] The sector teeth on the four sides of the round seat start to rotate. Due to the meshing, the round seat rotates on its own, and the engaging seat connected to the round seat rotates accordingly. Finally, the heating nozzle connected to the heating tube starts to heat, dry and disinfect the transmitted test paper card strip and the test paper body in all directions, thereby disinfecting the residual gas in the box and avoiding moisture in the test paper body, thus avoiding failure of blood sugar test;

[0020] The transfer roller is gradually driven to the highest point by the electric control push rod. After the transfer roller is at the highest position, the solid liquid abuts the test paper strip and the test paper body. The test paper body is stably exposed at the detection port, thereby achieving the stability of the test paper body during blood sugar testing and ensuring the accuracy of the test results.

This process often leads to the situation of blood contamination of the detection area mentioned in the background technology. In view of the above situation, a disinfection structure is added in the detection area. Although it has a disinfection effect, due to the risk of contact between the disinfection structure and the membrane electrode, the detection efficiency is reduced, the normal reaction of the enzyme electrode is affected, the detection accuracy is reduced, and the detection failure occurs;

[0037] In response to the above problems, the paper feeding module includes a paper feeding roller 501, a transfer roller 502 and a winding roller 503 which are symmetrically arranged inside the main body 100 of the blood glucose testing device. A transfer roller 502 is arranged between the winding roller 503 and the paper feeding roller 501 and is located directly below the detection port 200. The paper feeding roller 501, the transfer roller 502 and the winding roller 503 are connected by a transmission mechanism 522. The transmission mechanism 522 simultaneously drives the three rollers to start rotating. A transmission port 504 is arranged on one side of the paper feeding roller 501 and is opened on the main body 100 of the blood glucose testing device. A test paper strip 505 is placed on the transmission port 504 during the detection process. The material of the test paper strip 505 can be aluminum, plastic, etc., because it is finally wound on the winding roller. 503, it needs to have a certain degree of ductility. There are multiple groups of bayonet holes 506 arranged in an array on the test paper card strip 505, and the test paper body 507 can be detachably placed in the bayonet hole 506. It should be noted that unlike traditional test paper, the test paper body 507 is slightly bent due to the curved surface of the transfer roller 502 when it is transmitted to the highest point. The test paper body 507 is selected as Roche blood glucose test paper. The test paper body 507 is stuck in the bayonet hole 506, and finally the test paper card strip 505 is wound on the winding roller 503. This part of the test paper body 507 can be collected uniformly to avoid arbitrary discarding. The test paper card strip 505 passes through the paper feeding roller 501 and the transfer roller 502 in turn and the tail end is wound on the winding roller 503.

[0038] Embodiment 2, on the basis of embodiment 1: mounting blocks 508 are symmetrically arranged at the left and right ends of the transfer roller 502, the transfer roller 502 is rotatably connected to the two groups of mounting blocks 508, and the bottoms of the two groups of mounting blocks 508 are fixedly connected with electric control push rods 509, each electric control push rod 509 is vertically fixedly installed on the suspension 510, in order to ensure that the mounting block 508 is lifted under the action of the electric control push rod 509 and the lifting is not offset, guide rods 511 penetrating the mounting block 508 are symmetrically arranged at both ends of the suspension 510, and the two mounting blocks 508 are slidably connected to the corresponding guide rods 511 respectively.

[0039] In order to avoid the reaction and contact between the disinfection component and the enzyme electrode, a disinfection component is set at the bottom of the suspension 510 to separate the detection area and the disinfection area. The disinfection component includes a disinfection box 600 installed at the bottom of the suspension 510. The air disinfection component can be installed inside the disinfection box 600. The disinfection box 600 is symmetrically provided with disinfection ducts 601 along the axis of the transfer roller 502. The other ends of the two disinfection ducts 601 are fixedly installed with disinfection seats 602. The middle of the two disinfection seats 602 is provided with a through hole 603 for the detection test paper body 507 to pass through. The upper part of the disinfection seat 602 can be installed The ultraviolet disinfection lamp directly disinfects the detection surface of the test paper body 507, and the bottom of the disinfection seat 602 connected to the disinfection conduit 601 can transmit air disinfection gas. Therefore, it can be seen from the above that the separation of the disinfection area and the detection area can largely avoid the adverse reaction between the disinfection operation and the enzyme electrode, and the disinfection area can disinfect the transmitted test paper strip 505 during the transmission process through the through hole 603, which does not affect the detection efficiency and avoids the reduction of the disinfection effect. At the same time as the separation and disinfection, the disinfection and detection operations are still integrated to ensure the detection efficiency.

[0040] Embodiment 3, based on Embodiment 1 and Embodiment 2: The front and rear ends of the transfer roller 502 are rotatably mounted with a transmission pipe 512 through fasteners, and the other ends of the two transmission pipes 512 are connected to a liquid adding pipe 513, and the liquid adding pipe 513 is provided with a vertical pipe 514 on which an electric control valve is installed. The outer sleeve of the liquid adding pipe 513 is provided with an electromagnet 515, so the material of the liquid adding pipe 513 needs to have good conductivity, and the outer sleeve of the electromagnet 515 is surrounded by an electromagnetic coil 516, and the electromagnetic coil 516 The battery assembly is electrically connected via a conductor 517, and magnetorheological fluid is injected into the liquid adding pipe 513. It should be noted that when the electromagnetic coil 516 is energized, the electromagnet 515 generates magnetism. Therefore, after the magnetorheological fluid in the liquid adding pipe 513 senses the magnetic field and magnetism, the magnetorheological fluid changes from a low-viscosity fluid to a solid form with controllable yield strength. After the magnetorheological fluid becomes solid, magnetorheological fluid is gradually added through the vertical pipe 514, and the magnetorheological fluid eventually enters the transfer roller 502 from a solid state.

[0041] In the above, after the solid magnetorheological fluid enters the transfer roller 502, the solid magnetorheological fluid is released from the expansion holes 518 because a plurality of expansion holes 518 are arrayed at the upper end of the transfer roller 502. During this process, the electric control push rod 509 starts to gradually drive the transfer roller 502 to the highest point. After the transfer roller 502 is at the highest position, the solid liquid abuts the test paper strip 505 and the test paper body 507. The test paper body 507 is stably exposed at the detection port 200, thereby achieving the stability of the test paper body 507 during the blood sugar detection process and ensuring the accuracy of the test results. The upper end of the transfer roller 502 is hollow, and the lower end of the transfer roller 502 is solid.

[0042] A mounting base 519 is provided between the transfer roller 502 and the winding roller 503. The mounting base 519 is fixedly installed inside the main body 100 of the blood glucose testing device, and a cylinder 520 is provided at the bottom of the mounting base 519. The other end of the cylinder 520 is connected to the detection component 521. After the detection is completed, since the winding roller 503 continues to wind, the detected test paper main body 507 is gradually transmitted to the winding roller 503. Then the detection component 521 provided in this process specifically includes a camera, which transmits the color performance of the test paper to the display screen as a reference for the test results.

[0043] In order to ensure the drying and further disinfection of the test paper body 507, a vertical plate 700 is installed on the inner wall of one side of the blood glucose testing equipment body 100 close to the transmission port 504, and an air insulation module is installed on the vertical plate 700. The air insulation module includes a round seat 701 arranged in the middle of the vertical plate 700, and the round seat 701 and the vertical plate 700 are provided with an opening 702 matching the transmission port 504 for transmitting the test paper strip 505. A toothed disc 703 is embedded on the outer wall of the round seat 701, and fan teeth 704 are meshed and connected on four sides of the toothed disc 703. The four fan teeth 704 are all connected to a driving shaft 705 with corresponding keys. Each driving shaft 705 is provided with a transmission wheel 706, and the four transmission wheels 706 are all connected with a transmission belt 707 for transmission.

[0044] The round seat 701 is provided with an adjustment groove 708 on one side close to the transfer roller 502, and a fitting seat 709 is clamped in the adjustment groove 708. The fitting seat 709 is rotatably connected to a heating tube 711 whose other end is connected to a heating nozzle 713 through a linkage seat 710. After the rotation of the driving shaft 705, the sector teeth 704 on the four sides of the round seat 701 start to rotate due to the transmission of the transmission belt 707. Due to the meshing, the round seat 701 rotates, and the fitting seat 709 clamped on the round seat 701 rotates accordingly. Finally, the heating nozzle 713 connected to the heating tube 711 starts to heat, dry and disinfect the transmitted test paper strip 505 and the test paper body 507 in all directions, thereby disinfecting the residual gas in the box while avoiding the moisture of the test paper body 507 and avoiding the failure of blood glucose detection. Both heating tubes 711 are connected to a hot air transmission tube 712, and the hot air transmission tube 712 is connected to an external heating component.
