Abstract
Description
Technical Field
[0001] This application relates to the technical field of blood glucose testing devices, and in particular to a dynamic biochemical collector. Background Technology
[0002] Diabetes is a common disease, and for diabetic patients, measuring blood sugar is an essential daily task. However, measuring blood sugar alone is far from sufficient to address the issue of blood ketone levels caused by problems with blood sugar metabolism.
[0003] For diabetic patients, diabetic ketoacidosis or diabetic ketoacidosis is the most common emergency. If not treated in time and properly, the mortality rate is high. However, most dynamic blood sampling devices on the market usually only monitor blood glucose and have weak or no ability to monitor blood ketone levels. Moreover, dynamic blood sampling devices on the market are usually disposable and have high costs for long-term use. Therefore, there is an urgent need for a device that can detect both blood glucose and blood ketone levels at the same time. Summary of the Invention
[0004] To address the issue that traditional blood glucose monitoring devices can only monitor blood glucose levels but not blood ketone levels, this application provides a dynamic biochemical data acquisition device.
[0005] The dynamic biochemical collector provided in this application adopts the following technical solution:
[0006] A dynamic biochemical data acquisition device includes a mounting box, a blood glucose probe and a blood ketone probe housed within the mounting box, and a power supply within the mounting box. The mounting box also houses a dual-channel control chip. The power supply powers the blood glucose probe, blood ketone probe, and control chip. The blood glucose probe and blood ketone probe are used to collect blood glucose and blood ketone information, respectively. The control chip receives blood glucose and blood ketone information through two communication channels. A communication module is also located within the mounting box and is electrically connected to the control chip. The communication module outputs the signals processed by the control chip. This technical solution allows for the simultaneous collection of blood glucose and blood ketone information by the blood glucose probe and blood ketone probe. The collected information is then processed by the control chip with two signal receiving channels and transmitted via a signal transmission module to an information processing center for further processing, achieving synchronous acquisition of blood glucose and blood ketone information.
[0007] The above technical solution enables the simultaneous detection of blood glucose and blood ketone information in human tissue fluid using blood glucose probes and blood ketone probes. The information is then received by a dual-channel control chip and output through a communication module, thus achieving synchronous monitoring of blood glucose and blood ketones.
[0008] Optionally, the blood glucose probe and the blood ketone probe have the same structure. The blood glucose probe includes an electrode probe, an insertion needle, and a mounting cylinder made of insulating material. The mounting cylinder is located in the mounting box. The electrode probe is used to electrically connect with the control chip to transmit signals. One end of the electrode probe is inserted into the mounting cylinder. One end of the insertion needle is used to puncture human skin. The other end of the insertion needle is located in the mounting cylinder. The end of the insertion needle located inside the mounting cylinder is provided with an arc-shaped connecting plate made of elastic material. When the insertion needle is installed in the mounting cylinder, the connecting plate abuts against the inner wall of the mounting cylinder. At this time, the insertion needle is electrically connected to the electrode probe.
[0009] Optionally, the insertion needle includes a needle body and several electrodes. One end of the needle body is the insertion end, and the electrodes are disposed at the insertion end of the needle body. The electrodes are insulated from the needle body. The electrodes are divided into three groups, which are defined as a working electrode group, a counter electrode group, and a reference electrode group, respectively. Both the working electrode group and the counter electrode group are provided with several electrodes, and the electrodes of the working electrode group and the counter electrode group are connected in series with each other. The connecting plate is connected to the other end of the needle body except for the insertion end. The outer wall of the connecting plate is provided with three first metal contacts circumferentially around its axis. The connecting plate is insulated from the first metal contacts. The inner wall of the mounting cylinder is provided with three second metal contacts spaced apart circumferentially around its axis. The three first metal contacts are connected in series with the three groups of electrodes, respectively. When the needle body and the connecting plate are installed in the mounting cylinder, the connecting plate is pressed against the inner wall of the mounting cylinder, and the three first metal contacts abut against the three second metal contacts, respectively. The three second metal contacts are connected in parallel with the electrode needles.
[0010] Optionally, the electrode contact pin includes a bracket and three conductive strips. The bracket has an axis, and the three conductive strips are circumferentially spaced around the axis of the bracket. The three conductive strips are insulated from each other. When one end of the electrode contact pin is inserted into the mounting cylinder, the three conductive strips respectively abut against three second metal contacts.
[0011] Optionally, the bracket includes a connecting column, an isolation plate, and a connecting sleeve made of insulating material. Three isolation plates are provided and circumferentially spaced around the axis of the connecting column on its sidewall. The connecting sleeve is cylindrical and coaxially disposed at one end of the connecting column. One end of the isolation plate extends into the connecting sleeve and is flush with the end of the connecting sleeve away from the connecting column. Three conductive strips are fixed between two isolation plates, with one end of each conductive strip extending into the connecting sleeve and flush with the end of the connecting sleeve away from the connecting column. An insulating material clamping bolt is threaded onto the end of the connecting sleeve away from the connecting column. The clamping bolt is used to fix the end of the conductor to the end of the connecting sleeve. When the connecting column and the three conductive strips are inserted into the mounting sleeve, the end of the connecting sleeve abuts against the end of the mounting sleeve.
[0012] Optionally, the conductive strips have different widths. The area enclosed by two adjacent isolation plates is defined as the installation area. The three conductive strips are respectively fitted into the three installation areas. The three second metal contacts are all elongated, and the width of the three second metal contacts corresponds to the width of the three conductive strips. When the end of the electrode needle is correctly inserted into the installation cylinder, the three second metal contacts are fitted into it. In the corresponding installation area, the three first metal contacts on the connecting plate are also elongated, and the width of the three first metal contacts corresponds to the width of the three second metal contacts. The outer wall of the connecting plate has a groove for embedding. The three first metal contacts are embedded into the grooves. When the connecting plate is correctly inserted into the installation cylinder, the three second metal contacts are embedded into the three grooves. The protruding part of the connecting plate between two adjacent grooves is embedded between the two second metal contacts and abuts against the inner wall of the installation cylinder.
[0013] Optionally, both ends of the connecting plate are provided with push rods, one end of each push rod extends toward the insertion end of the insertion needle, and the ends of the two push rods away from the connecting plate are connected to each other. The push rods are made of elastic material. When the connecting plate is inserted into the mounting cylinder, the push rods push the connecting plate against the inner wall of the mounting cylinder.
[0014] Optionally, one end of the push rod is bent and extended away from the connecting plate. The part of the push rod connected to the connecting plate is defined as the vertical end, and the bent and extended part of the push rod is defined as the bent end. The end of the mounting cylinder used to connect the insertion needle is provided with a receiving groove. The receiving groove penetrates the inner wall of the mounting cylinder. When the connecting plate is correctly installed in the mounting cylinder, the bent end of the push rod is embedded in the receiving groove.
[0015] Optionally, the inner walls at both ends of the receiving groove are provided with limiting blocks. The limiting blocks are located on the side of the receiving groove facing the inner hole of the mounting cylinder. When the bent end of the push rod is located in the receiving groove, the limiting block abuts against the side wall at the junction of the vertical end and the bent end of the push rod.
[0016] Optionally, the insertion pin is connected to the middle of the connecting plate, and the middle of the connecting plate away from the insertion pin is provided with a positioning port. The inner wall of the mounting cylinder is provided with a positioning block. When the bent end of the push rod is embedded in the receiving groove, the positioning block is embedded in the positioning port.
[0017] In summary, this application simultaneously detects blood glucose and blood ketone information in human tissue fluid using blood glucose and blood ketone probes. The information is then received by a dual-channel control chip and output through a communication module, achieving synchronous monitoring of blood glucose and blood ketones. Furthermore, by modularizing the blood glucose and blood ketone probes, the insertion needles of the probes can be replaced after use, allowing the remaining parts to be used sustainably. This reduces usage costs and is also conducive to the construction of a green ecosystem. Attached Figure Description

[0033] The following is in conjunction with the appendix Figures 1-13 This application will be described in further detail.
[0034] This application discloses a dynamic biochemical collector, referring to... Figure 1 , Figure 2 and Figure 13 It includes an installation box 1 made of insulating material, a blood glucose probe 2 and a blood ketone probe 3 installed in the installation box 1, a temperature sensor 10 installed in the installation box 1, and a power supply installed in the installation box 1.
[0035] The mounting box 1 includes a lower cover 12 and an upper cover 11. The blood glucose probe 2, blood ketone probe 3, temperature sensor 10, and power supply are all located in the lower cover 12. The lower cover 12 has a battery compartment, and the power supply includes a button battery installed in the battery compartment to provide power.
[0036] A dual-channel control chip is fixedly installed inside the top cover 11. The control chip adopts the ADUCM355BCCZ chip. The ADUCM355BCCZ chip integrates two AFE modules, which can simultaneously acquire signals from two three-electrode 52 sensors. The current signals of the blood ketone probe 3 and the blood glucose probe 2 are respectively connected to the two AFE modules.
[0037] The ADUCM355BCCZ chip has a communication serial port, and a communication module is located inside the top cover 11. The communication module includes a Bluetooth module. The communication serial port and the Bluetooth module are electrically connected to communicate. The sampled sensor signals are output to a personal terminal or data processing terminal through the Bluetooth module for real-time transmission of sampled data.
[0038] The upper cover 11 is detachably installed on the lower cover 12. When the upper cover 11 and the lower cover 12 are assembled, the control chip is electrically connected to the power supply, and the blood glucose probe 2, blood ketone probe 3 and temperature sensor 10 are electrically connected to the control chip. The control chip controls the current supplied to the blood ketone probe 3, blood glucose probe 2 and temperature sensor 10.
[0039] Reference Figure 1 —6 and Figure 12 , 13 The blood glucose probe 2 and the blood ketone probe 3 have the same structure. The lower cover 12 is integrally equipped with three mounting tubes, two of which are used to install the blood glucose probe 2 and the blood ketone probe 3, and the remaining one is used to install the temperature sensor 10.
[0040] The blood glucose probe 2 includes an electrode probe 4, an insertion needle 5, and an installation tube 6. The installation tube 6 is inserted into the installation tube.
[0041] The insertion needle 5 includes a needle body 51 and a connecting plate 7. The connecting plate 7 is made of an elastic material and is arc-shaped. One end of the needle body 51 is inserted into human skin, and the other end of the needle body 51 is fixedly connected to the connecting plate 7. Several electrodes 52 are provided on the outer wall of the end of the needle body 51 that is inserted into human skin. The electrodes 52 are insulated from the needle body 51. The insulation method is a conventional technique, which can be selected by those skilled in the art according to the actual situation. The electrodes 52 are divided into three groups, which are defined as the working electrode group 53, the counter electrode group 54, and the reference electrode group 55, respectively. The working electrode group 53 and the counter electrode group each have several electrodes 52 connected in series; in this embodiment, two are used. The counter electrode group 54 is configured with one electrode 52.
[0042] By using several identical electrodes 52 in series for detection, the detected current signal becomes larger and more stable, and is less susceptible to external interference.
[0043] Reference Figure 1 —6 and Figure 12 , 13The working electrode 52 has a glucose oxidase layer coated on its surface. A current is generated through a chemical reaction between the glucose oxidase layer and the human tissue fluid. By detecting the magnitude of this current, the glucose content in the human tissue fluid can be detected, thereby detecting the blood glucose level. The counter electrode 52 and the reference electrode 52 are used to assist in the stable transmission of the current signal. The working electrode 52, counter electrode 52, and reference electrode 52 are all existing technologies, and those skilled in the art can select them according to the actual situation.
[0044] On the working electrode 52 of the blood ketone probe 3, the glucose oxidase layer was replaced with a β-hydroxybutyrate dehydrogenase layer.
[0045] Reference Figure 1 —6. Three elongated metal contacts 71 are provided circumferentially around the outer wall of the connecting plate 7, with their lengths parallel to the axis of the connecting plate 7. The first metal contacts 71 are fixedly mounted to the outer wall of the connecting plate 7. The widths of the three first metal contacts 71 are all different, resulting in different intervals between them. Three sets of electrodes 52 are connected in series with the three first metal contacts 71.
[0046] Reference Figure 1 —6. The mounting cylinder 6 is cylindrical, and three elongated second metal contacts 64 are fixedly mounted circumferentially around its inner wall. The three second metal contacts 64 are fitted against the inner wall of the mounting cylinder 6. The width of the three second metal contacts 64 corresponds one-to-one with the width of the three first metal contacts 71, and the first metal contacts 71 and the second metal contacts 64 can fit together. The connecting plate 7 is protruding 651 between two first metal contacts 71. The part between the protrusions 651 of the connecting plate 7 where the first metal contacts 71 are embedded is defined as the embedding groove 72, and the first metal contacts 71 are located in the embedding groove 72.
[0047] Reference Figure 1 —6. The connecting plate 7 is used to fix the needle body 51 to the mounting cylinder 6. The protrusions 73 of different widths between the two first metal contacts 71 of the connecting plate 7 and the intervals of different widths between the second metal contacts 64 inside the mounting cylinder 6 slide and engage accordingly. When the connecting plate 7 is inserted into the mounting cylinder 6 and the protrusions 73 of the connecting plate 7 slide and are installed in the intervals between the first metal contacts 71 and the second metal contacts 64 of corresponding widths, the first metal contacts 71 and the second metal contacts 64 are correctly fitted and connected.
[0048] By using the cooperation between the first metal contact 71 and the second metal contact 64 with different widths, and the sliding cooperation between the protrusion 73 of the connecting plate 7 with different widths and the second metal contact 64 inside the mounting cylinder 6, the first metal contact 71 and the second metal contact 64 will not be misaligned when the connecting plate 7 is inserted into the mounting cylinder 6. As a result, when the working electrode group 53, the counter electrode group 54 and the reference electrode group 55 on the needle body 51 are connected to the control chip, the current delivered by the control chip can be transmitted to the correct electrode group 52, and the signal detected by the working electrode 52 can also be transmitted to the control chip along the correct route.
[0049] Reference Figure 1 —6. The electrode contact 4 includes a bracket 41 made of insulating material, three conductive strips 42, and a clamping bolt 414 made of insulating material. The bracket 41 includes a connecting post 411, an isolation plate 412, and a connecting sleeve 413 made of insulating material.
[0050] The isolation plate 412 is provided in three pieces and is integrally disposed around the axis of the connecting column 411 on the side wall of the connecting column 411. The connecting sleeve 413 is cylindrical and is integrally disposed on one end of the connecting column 411. One end of the isolation plate 412 extends into the connecting sleeve 413 and is flush with the end of the connecting sleeve 413 away from the connecting column 411. The isolation plate 412 is integrally connected to the inner wall of the connecting sleeve 413.
[0051] The space enclosed by two adjacent isolation plates 412 is defined as the installation area 415. Three conductive strips 42 are respectively fixedly embedded in the three installation areas 415, and one end of the conductive strip 42 extends into the connecting sleeve 413 and is flush with the end of the connecting sleeve 413 away from the connecting post 411. The tightening bolt 414 is threadedly installed on the end of the connecting sleeve 413 away from the connecting post 411.
[0052] Reference Figure 1 —6. The three isolation plates 412 are respectively slidably engaged with the intervals between the three second metal contacts 64 inside the mounting cylinder 6. One end of the electrode contact 4 is slidably engaged with the mounting cylinder 6. When one end of the electrode contact 4 is slidably inserted into the mounting cylinder 6, the three isolation plates 412 are respectively slidably installed in the intervals between the three second metal contacts 64, and at the same time, the three conductive strips 42 are respectively attached and tightly connected to the three second metal contacts 64. When the connecting post 411 and the three conductive strips 42 are inserted into the mounting sleeve, the end of the connecting sleeve 413 is pressed against the end of the mounting sleeve. The end of the mounting sleeve that is pressed against the connecting sleeve 413 is provided with a retaining ring 65. The connecting sleeve 413 is pressed against the mounting sleeve, thereby pushing the retaining ring 65 to be attached and pressed against the end of the connecting tube.
[0053] Reference Figure 1—6, The third connecting tube also has an installation sleeve and an electrode contact 4 inserted in it. The temperature sensor 10 is connected to the electrode contact 4 in the same way as the blood ketone probe 3 and the blood glucose probe 2. The electrode contact 4 in the third connecting tube has only two conductive strips 42, and the installation cylinder 6 in the third connecting tube has only two second metal contacts 64.
[0054] The mounting box 1 contains a first conductor 8, which includes a substrate 81 made of insulating material and a signal transmission strip 83 made of conductive material. In this embodiment, copper is used. One end of the substrate 81 is integrally provided with three connecting rings, and the areas corresponding to the three connecting rings are respectively designated as the first area, the second area, and the third area. The connecting ring corresponding to the first area is connected to the connecting sleeve 413 of the electrode probe 4 of the blood glucose probe 2, the connecting ring corresponding to the second area is connected to the connecting sleeve 413 of the electrode probe 4 of the blood ketone probe 3, and the connecting ring corresponding to the third area is connected to the connecting sleeve 413 of the electrode probe 4 of the temperature sensor 10.
[0055] The first zone has three signal transmission strips 83, which are bonded together. An insulating layer 84 is provided between two adjacent signal transmission strips 83 to insulate them from each other. One end of the signal transmission strip 83 extends to the connecting ring. The ends of the three signal transmission strips 83 are surrounded to form a ring. The end of the signal transmission strip 83 located at the connecting ring passes through the connecting ring and abuts against the end of the corresponding conductive strip 42.
[0056] The second zone, like the first zone, has three signal transmission strips 83. The third zone has two signal transmission strips 83, and the setting method is the same as that in the first zone.
[0057] Referring to the figure, the detection head 13 is detachably mounted on the lower cover 12, and the three electrode pins 4 and the first lead wire 8 are all fixedly installed in the detection head 13. The three connecting rings of the first lead wire 8 are coaxially disposed at the ends of the connecting sleeves 413 of the three electrode pins 4. The three connecting rings are fixed to the ends of the connecting sleeves 413 of the three electrode pins 4 by tightening the clamping bolts 414. At this time, the end of the conductive strip 42 of any electrode pin 4 is correspondingly and tightly connected to the signal transmission strip 83 of the first lead wire 8.
[0058] One end of the electrode contact pin 4 extends from the detection head 13. The retaining ring 65 has an integrally formed protrusion 651 on one side of the connecting tube, and a groove is opened on the end face of the connecting tube. The protrusion 651 and the groove are interlocked and fitted together. During installation, the mounting cylinder 6 is first inserted into the connecting tube, and the protrusion 651 is fitted into the groove. Then, the detection head 13 is installed onto the lower cover 12. At this time, one end of each of the three electrode contact pins 4 is inserted into the three mounting cylinders 6, and the conductive strip 42 of the electrode contact pin 4 is respectively abutted and connected to the corresponding second metal contact 64 in the mounting cylinder 6.
[0059] The detection head 13 presses the connecting sleeve 413 of the electrode contact 4 against the retaining ring 65, and presses the retaining ring 65 against the end of the connecting tube. The position of the connecting sleeve 413 is positioned by the cooperation between the protrusion 651 of the retaining ring 65 and the groove of the connecting tube. At the same time, the isolation plate 412 of the bracket 41 inserted into the connecting sleeve 413 fixes the circumferential position of the second metal contact 64. This makes it less likely that the second metal contact 64 will rotate circumferentially due to the insertion and removal of the connecting plate 7 when the connecting plate 7 is inserted or removed, thus improving the overall service life.
[0060] Reference Figure 1 , Figure 5 —11, A push rod 9 is fixedly installed at both ends of the connecting plate 7. The push rod 9 extends towards the end of the needle body 51 that pierces the skin. The ends of the two push rods 9 are connected to each other, and the connected ends of the push rods 9 are bent in a direction away from the axis of the connecting plate 7. Both push rods 9 are made of elastic material.
[0061] The portion connecting the push rod 9 to the connecting plate 7 is defined as the vertical end 91, and the bent extension portion of the push rod 9 is defined as the bent end 92. The mounting cylinder 6 has a receiving groove 61 at one end for connecting the insertion needle 5. The receiving groove 61 penetrates the inner wall of the mounting cylinder 6. When the connecting plate 7 is correctly installed into the mounting cylinder 6, the bent end 92 of the push rod 9 is embedded in the receiving groove 61.
[0062] A limiting block 62 is integrally provided on the inner wall of both ends of the receiving groove 61. The limiting block 62 is located on the side of the receiving groove 61 facing the inner hole of the mounting cylinder 6. When the bent end 92 of the push rod 9 is located in the receiving groove 61, the limiting block 62 abuts against the side wall at the junction of the vertical end 91 and the bent end 92 of the push rod 9.
[0063] Reference Figure 1 , Figure 5 —11, the connection between the needle body 51 and the connecting plate 7 is located in the middle of the connecting plate 7. At the same time, a positioning port 74 is provided in the middle of the side of the connecting plate 7 away from the needle body 51. A positioning block 63 is fixedly installed on the inner wall of the mounting cylinder 6. When the bent end 92 of the push rod 9 is embedded in the receiving groove 61, the positioning block 63 is embedded in the positioning port 74.
[0064] When installing the connecting plate 7, firstly, the protruding part 73 of the connecting plate 7 is slidably installed between the two second metal contacts 64 on the inner wall of the mounting cylinder 6. Then, the connecting plate 7 is pushed to slide by the push rod 9. When the push rod 9 pushes the connecting plate 7 to slide to the bending part of the push rod 9 and presses against the limiting block 62, the push rod 9 is pushed further. Since the push rod 9 is made of elastic material, the push rod 9 will undergo elastic deformation and be embedded in the receiving groove 61, thus completing the fixation of the connecting plate 7 and the needle body 51.
[0065] Reference Figure 1 ,Figure 5 —11. Since the connecting plate 7 is pushed by the push rod 9, the needle body 51 and the electrode 52 on the needle body 51 will not be touched during the installation of the insertion needle 5, which is more hygienic to use, and the electrode 52 is less likely to be damaged during the installation of the insertion needle 5.
[0066] During use, the positioning block 63 provides support, making it less likely for the connecting plate 7 to shift when the needle 51 is inserted into the skin. The needle 51 can be inserted to the specified depth and is more stable during insertion, making it less likely to cause secondary damage to the skin.
[0067] When the needle body 51 is pulled out, the needle body 51 can be pulled out smoothly due to the cooperation between the push rod 9 and the limit block 62.
[0068] Reference Figure 1 , Figure 5 —11, A second wire with the same structure as the first wire 8 is also fixedly installed inside the upper cover 11. The second wire is electrically connected to the control chip. The only difference between the second wire and the first wire 8 is that the second wire does not have a connecting ring at its end. At the same time, one end of the second wire is tapered. The end of the first wire 8 away from the detection head 13 has a V-shaped groove that fits into the tapered end of the second wire. When the upper cover 11 and the lower cover 12 are assembled, one end of the second wire fits into the V-shaped groove.
[0069] The base plate 81 at one end of the first conductor 8 with a V-shaped groove is integrally provided with a fixing ring 82. The fixing ring 82 is fixed to the lower cover 12 by bolts, thereby supporting and fixing the end of the first conductor 8, making the connection between the second conductor and the first conductor 8 more stable.
[0070] Meanwhile, since the detection head 13, mounting cylinder 6, and insertion pin 5 are all modularly designed, the first two can be directly replaced by modular plugging and unplugging if damaged. After use, the insertion pin 5 can be pulled out and replaced with a new pin, which makes the overall service life of the equipment longer and the operating cost lower. When the power is depleted, the power supply can be replaced by opening the top cover 11.
[0071] The lower cover 12 is detachably fitted with adhesive tape, which is used to attach the lower cover 12 to the human body. The lower cover 12 is also detachably fitted with a protective cover, which covers the insertion needle 5.
[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
