Description

Technical Field

[0001] This invention belongs to the field of medical testing equipment technology, and specifically relates to a home-use human body testing device that combines blood glucose, uric acid, and blood ketones. Background Technology

[0002] With the continuous development of home medical products, consumer demand for simple medical diagnostic products is constantly increasing. Home medical products must not only have an appealing appearance but also ensure good handheld usability. To accommodate the elderly, large-screen displays and voice-reported test results are highly competitive in the market. For such multifunctional devices, a compact design suitable for handheld operation makes a rational spatial layout particularly important.

[0003] A search revealed that Chinese Patent Publication No. CN214539261U, authorized on October 29, 2021, discloses an endocrinology uric acid detection device. The device includes a detection box, with a test strip box, a timer, and a colorimetric plate fixedly connected from left to right at the top. A rotating groove is formed in the middle of the inner wall of the detection box, and a connecting rod is evenly rotatably connected within the groove. A rotating ring is fixedly connected to the ends of the connecting rods, and a sample collection cup is disposed within the rotating ring. The sample collection cup is fixedly connected to the rotating ring via a fixing mechanism. A driving mechanism for rotating the rotating ring is installed at the bottom of the detection box. This application, by incorporating a timer, detection box, test strip box, and colorimetric plate, allows medical personnel to control the test time of the test strips within a reasonable range, avoiding excessively short or long test times that could affect the test results. Simultaneously, it allows for even rinsing of the sample collection cup with clean water, improving rinsing efficiency and cleaning effect.

[0004] However, the device still has the following drawbacks: although it can avoid the test results from being too short or too long, the accuracy of the test strip recognition is generally required to be high, the conditions for using the test strip are also affected by the environment, and the cumbersome card insertion method of the test strip is time-consuming and laborious. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a home-use three-in-one human body detection device for blood glucose, uric acid, and blood ketones, comprising an upper housing and a lower housing. The top of the lower housing is connected to the top of the upper housing, and a cutting assembly is rotatably connected to one side of the top of the upper housing. A driving assembly is rotatably connected to the inner wall of the upper housing, and a test strip is driven onto the driving assembly. A drying assembly is installed at the bottom of the upper housing, near the cutting assembly. A winding assembly is located on the side of the driving assembly away from the cutting assembly, and the winding assembly is driven onto the other end of the test strip. An ultraviolet lamp is also located on the side of the winding assembly away from the driving assembly.

[0006] Furthermore, the cutting assembly includes a positioning ring; a conical cover is fixedly connected to the inner wall of the positioning ring, and a positioning hole is provided at the center of the central axis of the conical cover, and cutting grooves are provided on both sides of the inner wall of the conical cover.

[0007] Furthermore, both sets of cutting grooves are interconnected with positioning holes, and the two sets of cutting grooves are symmetrically arranged with the central axis of the positioning ring as the center. A sealing cover is rotatably connected to one side of the top of the positioning ring, and a light source for irradiating the test strip is provided at the bottom of the sealing cover.

[0008] Furthermore, the drive assembly includes two sets of drive limiting rings; each set of drive limiting rings has an adjustment groove on its outer wall and near the top side, and a pressure rod is laterally slidably connected in the adjustment groove, with a linkage collar rotatably connected to both ends of the pressure rod.

[0009] Furthermore, pressure rollers are rotatably connected to the center of the central axis of both sets of drive limiting rings, and positioning collars are rotatably connected to both ends of the pressure rollers. A tension spring is elastically connected between the top end of the positioning collar and the bottom end of the linkage collar.

[0010] Furthermore, a drive rod is embedded at the center of the central axis of the pressure roller, and both ends of the drive rod are rotatably connected to the inner wall of the positioning collar. A handwheel is fixedly connected to one end of the drive rod.

[0011] Furthermore, the winding assembly includes a winding rod; the outer wall of the winding rod is fixedly connected to one end of the test strip, and two sets of winding limiting rings are fixedly connected to the outer wall of the winding rod, and the two sets of winding limiting rings are used to limit the test strip in the winding state on the outer wall of the winding rod.

[0012] Furthermore, the drying component includes an airflow duct; the airflow duct is laterally connected to one side wall of the lower housing of the detector, one end of the airflow duct is connected to a micro air pump, and the bottom end of the micro air pump is fixedly connected to the bottom end of the inner wall of the lower housing of the detector.

[0013] Furthermore, the top of the airflow duct and the side near the micro air pump are connected to an extension tube, and the other end of the extension tube is connected to a bend. The outer wall of the bend and the side away from the micro air pump are provided with several sets of air holes. The bend and the ultraviolet lamp are symmetrically arranged with the central axis of the winding rod as the center. The outer wall of the airflow duct and the side away from the micro air pump are connected to several diversion tubes.

[0014] Furthermore, the other end of each of the several groups of diverter tubes extends to the bottom of the inner wall of the conical groove, and the ends of the several groups of diverter tubes are closed. The end of the airflow duct and the side near the several groups of diverter tubes extend to the center of the central axis at the bottom of the inner wall of the conical groove. A miniature electric push rod is also embedded in the inner wall of the airflow duct, and the output end of the miniature electric push rod is connected to a photoelectric sensor. A through hole is opened on the outer wall of each of the several groups of diverter tubes and the side near the photoelectric sensor.

[0015] The beneficial effects of this invention are:

[0016] 1. One end of the drive component moves one end of the test strip to the cutting component during rotation. Inside the cutting component, the user can easily contact the test strip with their pricked finger. The test strip provides the user's blood to the blood glucose, uric acid, and ketone analyzer for analysis. The cutting component can also cut a section of the test strip during rotation. The drying component can then push the cut section of the test strip upwards inside the cutting component. It can also dry the cutting component and the winding component. Combined with the continuous operation of the ultraviolet lamp, the test strip in the winding state is sterilized and disinfected, improving the ease of use of the test strip.

[0017] 2. By continuously pulling the linkage collar with the tension spring, the linkage collar gradually approaches the positioning collar. As the pressure rod slides along the inner wall of the adjusting groove, it presses one side of the test strip, ensuring that the pressed test strip remains firmly connected between the pressure rod and the pressure roller. During the rotation of the handwheel on the drive rod to one side, one end of the test strip is sequentially passed through the inlet and outlet during horizontal conveying. The inlet and outlet horizontally position both ends of the test strip within the conical groove, facilitating the user to drip blood from a pricked finger onto the test strip between the inlet and outlet, thus improving the stability of blood collection.

[0018] 3. The positioning ring is sealed by rotating the sealing cover, and the conical groove is sealed. Then, the output end of the micro electric push rod drives the photoelectric sensor to adjust the distance between the sensor and the test strip. When the blood reacts with the reagent, the light source on the sealing cover inside the instrument will illuminate the reaction area of ​​the test strip. The photoelectric sensor at the bottom of the test strip measures the intensity of the reflected light. Different concentrations of blood glucose, blood ketones, and uric acid will produce different color intensities, corresponding to different reflected light signals. The instrument calculates the concentration of each component in the blood based on this.

[0019] 4. The rotation of the positioning ring allows the built-in cutting grooves on both sides to cut the test strip. After the sealing cover separates from the positioning ring, the output end of the micro electric push rod pushes the photoelectric sensor upward, pushing out the cut test strip at its top. This facilitates the separation of the cut test strip from the conical groove. At this moment, the photoelectric sensor extends out of the airflow duct, making it easy to clean the surface of the photoelectric sensor with a wet wipe. When the micro electric push rod drives the photoelectric sensor back into the airflow duct, the continuous operation of the micro air pump delivers gas to several component flow tubes, and the airflow is delivered to different positions of the photoelectric sensor through the through holes to air dry the surface of the wiped photoelectric sensor, thereby improving the measurement accuracy of the photoelectric sensor for reuse.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a home-use three-in-one human body detection device for blood glucose, uric acid, and blood ketones, comprising an upper housing 1 and a lower housing 2; exemplarily, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown.

An ultraviolet lamp tube 8 is also provided on the side of the winding assembly 7 away from the driving assembly 4.

[0034] Furthermore, an LCD screen 9 and a control panel 10 are embedded and installed on one side of the top of the upper housing 1 of the detector. A conical groove 11 is provided on the other side of the top of the upper housing 1 of the detector. An inlet 12 is provided on the inner wall of the conical groove 11 and on the side closer to the control panel 10. An outlet 13 is provided on the inner wall of the conical groove 11 and on the side away from the inlet 12. Both the inlet 12 and the outlet 13 are fitted onto the outside of the test strip 5.

[0035] Two sets of partitions 14 are fixedly connected to the bottom of the inner wall of the lower housing 2 of the detector, and the two sets of partitions 14 are symmetrically arranged with the central axis of the lower housing 2 of the detector as the center. A first mounting hole 15 is opened on one side of both sets of partitions 14 and the lower housing 2 of the detector.

Two sets of second mounting holes 17 are opened on the outer wall of the lower housing 2 of the detector and on the side near the reserved groove 16. A support plate 18 is horizontally fixedly connected to the outer wall of the lower housing 2 of the detector and on the side near the reserved groove 16. A third mounting hole 19 is opened on the outer wall of the support plate 18.

[0036] Specifically, one end of the driving component 4 is used to move one end of the test strip 5 to the cutting component 3 during rotation. Inside the cutting component 3, it is convenient for the user to contact the test strip 5 with their pricked finger. The test strip 5 provides the user's blood to the blood glucose, uric acid, and blood ketone triple analyzer for analysis. The cutting component 3 can also cut a section of the test strip 5 during rotation. After that, the drying component 6 can push the cut section of the test strip 5 upwards inside the cutting component 3. It can also dry the inside of the cutting component 3 and the winding component 7. With the continuous operation of the ultraviolet lamp 8, the test strip 5 in the winding state is sterilized and disinfected.

[0037] The cutting assembly 3 includes a positioning ring 31; for example, such as Figure 5 As shown.

[0038] The inner wall of the positioning ring 31 is fixedly connected to a conical cover 32, and a positioning hole 33 is provided at the center of the central axis of the conical cover 32. Cutting grooves 34 are provided on both sides of the inner wall of the conical cover 32. Both sets of cutting grooves 34 are connected to the positioning hole 33, and the two sets of cutting grooves 34 are symmetrically arranged with the central axis of the positioning ring 31 as the center. A sealing cover plate 35 is rotatably connected to the top side of the positioning ring 31, and a light source for irradiating the test strip is provided at the bottom end of the sealing cover plate 35.

[0039] Furthermore, the bottom of the conical cover 32 is rotatably attached to the inner wall of the conical groove 11. The manual rotation of the conical cover 32 is used to cut the test paper strip 5 in the inlet 12 and outlet 13 using two sets of cutting grooves 34.

[0040] The driving component 4 includes two sets of driving limiting rings 41; for example, such as Figure 6 and Figure 7 As shown.

[0041] An adjustment groove 44 is provided on the outer wall and near the top of each of the two sets of drive limiting rings 41. A pressure rod 45 is laterally slidably connected in the adjustment groove 44. Both ends of the pressure rod 45 are rotatably connected to a linkage collar 46. A pressure roller 47 is rotatably connected at the center of the central axis of each of the two sets of drive limiting rings 41. Both ends of the pressure roller 47 are rotatably connected to a positioning collar 48. A tension spring 49 is elastically connected between the top of the positioning collar 48 and the bottom of the linkage collar 46. A drive rod 42 is embedded in the center of the central axis of the pressure roller 47. Both ends of the drive rod 42 are rotatably connected to the inner wall of the positioning collar 48. Both ends of the drive rod 42 are rotatably connected to the second mounting hole 17. A handwheel 43 is fixedly connected to one end of the drive rod 42. Both sets of positioning collars 48 are engaged with the inner wall of the reserved groove 16.

[0042] The winding assembly 7 includes a winding rod 71; for example, such as Figure 6 As shown.

[0043] The outer wall of the winding rod 71 is fixedly connected to one end of the test strip 5, and two sets of winding limiting rings 72 are fixedly connected to the outer wall of the winding rod 71. The two sets of winding limiting rings 72 are used to limit the test strip 5 in the winding state on the outer wall of the winding rod 71. Both ends of the winding rod 71 are rotatably connected to the inside of the first mounting hole 15, and a torsion spring is provided between the connection between the first mounting hole 15 and the winding rod 71.

[0044] The drying assembly 6 includes an airflow duct 61; for example, such as Figure 8 As shown.

[0045] The airflow duct 61 is transversely connected to one side wall of the lower housing 2 of the detector, and is located between two sets of partitions 14. One end of the airflow duct 61 is connected to a miniature air pump 62, and the bottom end of the miniature air pump 62 is fixedly connected to the bottom end of the inner wall of the lower housing 2 of the detector. The top of the airflow duct 61, near the miniature air pump 62, is connected to an extension tube 63, and the other end of the extension tube 63 is connected to a bend 64. Several sets of air holes 65 are opened on the outer wall of the bend 64, away from the miniature air pump 62. The bend 64 and the ultraviolet lamp tube 8 are symmetrically arranged with the central axis of the winding rod 71 as the center. The outer wall of the airflow duct 61, away from the micro air pump 62, is connected to several diversion tubes 66. The other end of each diversion tube 66 extends to the bottom of the inner wall of the conical groove 11, and the ends of the diversion tubes 66 are closed. The end of the airflow duct 61, near the diversion tubes 66, extends to the center of the central axis at the bottom of the inner wall of the conical groove 11. A micro electric push rod 67 is also embedded in the inner wall of the airflow duct 61, and the output end of the micro electric push rod 67 is connected to a photoelectric sensor 68. Through holes are opened on the outer wall of each diversion tube 66, near the photoelectric sensor 68.

[0046] Specifically, the tension spring 49 continuously pulls the linkage collar 46, causing the linkage collar 46 to gradually approach the positioning collar 48. During the sliding process of the pressure rod 45 on the inner wall of the adjustment groove 44, the pressure rod 45 presses one side of the test strip 5, so that the pressed test strip 5 is always closely connected between the pressure rod 45 and the pressure roller 47. During the rotation of the handwheel 43 on the drive rod 42 to one side, one end of the test strip 5 is passed through the inlet 12 and the outlet 13 in sequence during the horizontal conveying process. The inlet 12 and the outlet 13 are used to horizontally position both ends of the test strip 5 in the conical groove 11, so that the user can drip the blood from the pricked finger onto the test strip 5 between the inlet 12 and the outlet 13.

[0047] The rotation of the sealing cover plate 35 is used to seal the positioning ring 31, so that the conical groove 11 is in a sealed state. Then, the output end of the micro electric push rod 67 drives the photoelectric sensor 68 to adjust the distance between it and the test strip 5. When the blood and the reagent react chemically, the light source on the sealing cover plate 35 inside the detector will illuminate the reaction area of ​​the test strip 5. Then, the photoelectric sensor 68 located at the bottom of the test strip 5 measures the intensity of its reflected light. Different concentrations of blood glucose, blood ketones, and uric acid will produce different color intensities, corresponding to different reflected light signals. The instrument calculates the concentration of each component in the blood accordingly.

[0048] The rotation of the positioning ring 31 can cut the test strip 5 using the built-in cutting grooves 34 on both sides. After the sealing cover 35 separates from the positioning ring 31, the output end of the micro electric push rod 67 pushes the photoelectric sensor 68 upward, pushing out the cut test strip 5 at its top. This facilitates the separation of the cut test strip 5 from the conical groove 11. At this moment, the photoelectric sensor 68 extends out of the airflow duct 61, making it easy to clean and wipe the surface of the photoelectric sensor 68 with a wet wipe. When the micro electric push rod 67 drives the photoelectric sensor 68 back into the airflow duct 61, the micro air pump 62 continuously delivers gas to several component flow tubes 66 and uses through holes to deliver airflow to different positions of the photoelectric sensor 68 for drying the surface of the wiped photoelectric sensor 68, thereby improving the measurement accuracy of the photoelectric sensor 68 for reuse.

[0049] The working principle of the home-use blood glucose, uric acid, and blood ketone three-in-one human body detection device proposed in this invention is as follows:

[0050] By continuously pulling the linkage collar 46 through the tension spring 49, the linkage collar 46 gradually approaches the positioning collar 48. During the process of the pressure rod 45 sliding on the inner wall of the adjustment groove 44, the pressure rod 45 presses one side of the test strip 5, so that the pressed test strip 5 is always closely connected between the pressure rod 45 and the pressure roller 47. During the process of rotating the handwheel 43 on the drive rod 42 to one side, one end of the test strip 5 passes through the inlet 12 and the outlet 13 in sequence during the horizontal conveying process. The inlet 12 and the outlet 13 are used to horizontally position both ends of the test strip 5 in the conical groove 11, so that the user can drip the blood from the pricked finger onto the test strip 5 between the inlet 12 and the outlet 13.

[0051] The positioning ring 31 is sealed by rotating the sealing cover plate 35, so that the conical groove 11 is in a sealed state. Then, the output end of the micro electric push rod 67 drives the photoelectric sensor 68 to adjust the distance between it and the test strip 5. When the blood and the reagent react chemically, the light source on the sealing cover plate 35 inside the detector will illuminate the reaction area of ​​the test strip 5. The photoelectric sensor 68 located at the bottom of the test strip 5 measures the intensity of the reflected light. Different concentrations of blood glucose, blood ketones, and uric acid will produce different color intensities, corresponding to different reflected light signals. The instrument calculates the concentration of each component in the blood based on this.

[0052] The rotation of the positioning ring 31 allows the built-in cutting grooves 34 on both sides to cut the test strip 5. After the sealing cover 35 separates from the positioning ring 31, the output end of the micro electric push rod 67 pushes the photoelectric sensor 68 upward, pushing out the cut test strip 5 at its top. This facilitates the separation of the cut test strip 5 from the conical groove 11. At this moment, the photoelectric sensor 68 extends from the airflow duct 61, making it easy to clean and wipe the surface of the photoelectric sensor 68 with a wet wipe. When the micro electric push rod 67 drives the photoelectric sensor 68 back into the airflow duct 61, the micro air pump 62 continuously delivers gas to several component flow tubes 66 and uses through holes to deliver airflow to different positions of the photoelectric sensor 68 for drying the surface of the wiped photoelectric sensor 68, thereby improving the measurement accuracy of the photoelectric sensor 68 for reuse.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
