Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a portable multifunctional blood glucose and blood lipid analyzer. Background Technology

[0002] The blood glucose and lipid analyzer is a medical device that integrates modern biotechnology and intelligent design. It is designed for efficient and accurate health monitoring. The instrument can simultaneously detect multiple indicators in the blood, such as total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, triglycerides, and blood glucose. It is mainly used for home self-monitoring and for medical institutions to conduct immediate testing on patients. With its fast, accurate, and convenient detection performance, the blood glucose and lipid analyzer has become an important tool for chronic disease management and primary care.

[0003] Currently, portable blood glucose and lipid analyzers are widely used in ordinary households. In actual home use, when conducting tests, the test strip is often inserted into the instrument by hand. During this process, since the test strip is directly in contact with the hand, the testing area is easily contaminated by various impurities on the hand. This significantly increases the possibility of contamination of the test strip, which in turn adversely affects the accuracy of the analysis results and may lead to deviations in the test results.

[0004] Therefore, based on the above problems, we invented a portable multifunctional blood glucose and lipid analyzer. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0034] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a portable multifunctional blood glucose and blood lipid analyzer.

[0035] like Figures 1-12 As shown, a portable multifunctional blood glucose and lipid analyzer includes an analyzer body 1, a drawer slot 21 on the analyzer body 1, a drawer 2 inserted into the drawer slot 21, a test strip 50 placed in the drawer 2, a test strip slot 3 matching the test strip 50 on the drawer 2, a protective sleeve 51 covering the test strip 50, and a tear slit on the protective sleeve 51. The drawer 2 has a lifting mechanism for lifting the test strip 50 and a limiting component for limiting the position of the test strip 50. Specifically, the limiting component includes components disposed in the drawer 2. The inner wall has a buffer groove 4, and a wedge plate 5 is slidably installed in the buffer groove 4. It is worth mentioning that the side of the wedge plate 5 away from the bottom of the buffer groove 4 has a smooth inclined surface, which faces upward. The wedge plate 5 is fixedly installed to the bottom of the buffer groove 4 by a buffer spring 6. The drawer 2 is provided with a tearing mechanism for tearing the protective sleeve 51. The drawer slot 21 is provided with a slot 46 that matches the protective sleeve 51. The analyzer body 1 is provided with a bag discharge hole 45 for discharging the protective sleeve 51. The drawer slot 21 is provided with a pushing mechanism for pushing the test paper 50.

[0036] In order to stably lift the test paper 50 placed in drawer 2, a lifting mechanism is provided. The lifting mechanism includes a top plate 7 that is slidably connected to the inner wall of drawer 2. The bottom of drawer 2 is provided with a top groove 8. A limit rod 10 is fixed in the top groove 8. Two top blocks 9 and two top springs 11 are sleeved on the limit rod 10. The two ends of the top springs 11 are fixed to the top blocks 9 and the inner wall of the top groove 8, respectively. The top blocks 9 are slidably sleeved on the limit rod 10. The lower end of the top plate 7 is provided with a slide groove 13. Two sliders 14 are slidably installed in the slide groove 13. A scissor fork 12 is provided below the top plate 7. The upper ends of the scissor fork 12 are rotatably installed with the two sliders 14, respectively. The lower ends of the scissor fork 12 are rotatably installed with the two top blocks 9, respectively.

[0037] Through the above technical features: when multiple test papers are stacked in drawer 2, the test papers press down on top plate 7 by limiting the wedge plate 5. Top plate 7 is compressed by scissor fork 12 and top block 9 to top spring 11, so that the uppermost test paper 50 is always in a position flush with test paper slot 3, thereby ensuring that test paper 50 can be stably pushed out.

[0038] To tear open the protective sleeve 51, a tearing mechanism is provided. This mechanism includes two openings 15 on the drawer 2, each containing two inclined plates 16. It should be noted that each inclined plate 16 within the same opening 15 has an inclined surface on its opposite side, facing inwards towards the drawer 2. A rotating shaft 18 is located on one side of each inclined plate 16, and a drive roller 20 is coaxially mounted on the outside of the rotating shaft 18. A roller belt 17 is rotatably mounted on the outside of the inclined plates 16. It should be noted that the surface of the roller belt 17 is frosted to increase friction with the protective sleeve 51, enabling the roller belt 17 to reliably tear open the protective sleeve 51. The drive roller 20... Driven by the roller belt 7, the rotating shaft 18 is rotatably connected to the inclined plate 16 through the limiting block 19. The two rotating shafts 18 are connected by a gear set 22. Further, the gear set 22 includes a first connecting plate 24 disposed in the bag opening hole 15. Two intermediate shafts 25 are rotatably mounted on the first connecting plate 24. A second gear 28 is coaxially mounted on the intermediate shaft 25. The two second gears 28 are meshed with each other. A first gear 27 is coaxially mounted on each of the two rotating shafts 18. The two first gears 27 are meshed with the two second gears 28 respectively. A second connecting plate 26 is rotatably mounted between the rotating shafts 18 and the intermediate shafts 25 on the same side.

[0039] In this invention, the upper inclined plate 16 is fixed to the inner wall of the bag opening 15 by a fixing plate 29. A sliding groove 33 is provided on the inner wall of the bag opening 15, and a vertical rod 30 is fixed inside the sliding groove 33. A return spring 31 is sleeved on the vertical rod 30. A sliding plate 32 is slidably installed inside the sliding groove 33, and the vertical rod 30 slides through the sliding plate 32. The sliding plate 32 is fixed to the lower inclined plate 16. A lifting block 23 is rotatably connected to the lower rotating shaft 18. The inner wall of the bag opening 15 is provided with… The lifting groove 34, which is slidably installed with the lifting block 23, has a rotating shaft 18 rotatably passing through it on the upper side. A connecting rod 47 is provided on the side of the rotating shaft 18 away from the drawer 2. A connecting groove 48 is provided in the connecting rod 47. The connecting groove 48 is slidably connected to the rotating shaft 18. A connecting spring 49 is provided in the connecting groove 48. The two ends of the connecting spring 49 are fixed to the connecting groove 48 and the rotating shaft 18 respectively. The analyzer body 1 is provided with an association mechanism 35 for associating the rotating shaft 18 in the two strip removal holes 15.

[0040] In this invention, the correlation mechanism 35 includes a cavity 40 disposed within the analyzer body 1. Two correlation shafts 36 are rotatably mounted within the cavity 40. Both correlation shafts 36 rotatably penetrate the analyzer body 1 and extend to the drawer slot 21. A correlation motor 37 is installed within the cavity 40. One correlation shaft 36 and the drive shaft of the correlation motor 37 are coaxially mounted with pulleys 38. The two pulleys 38 are connected by a synchronous belt drive. The other correlation shaft 36 and the drive shaft of the correlation motor 37 are mounted with a transmission gear 39. The two transmission gears 39 are meshed and connected. The two correlation shafts 36 are connected to the two connecting rods 47 by splines.

[0041] Through the above technical features: the associated motor 37 drives two associated shafts 36 to rotate in opposite directions, the associated shafts 36, together with the connecting rod 47, drive the rotating shaft 18 to rotate, and the rotating shaft 18 drives another rotating shaft 18 to rotate through the gear set 22. At the same time, the rotating shaft 18 drives the drive roller 20 to rotate, and the drive roller 20 drives the roller belt 17 to rotate. At this time, the roller belt 17 can tear the protective sleeve 51 covering the drive roller 20 to both sides and discharge it through the bag discharge hole 45. On the one hand, when placing the test paper 50, it will not come into contact with the fingers under the protection of the protective sleeve 51, avoiding contamination. On the other hand, it is not necessary to replace the test paper 50 after each test, reducing the workload of the test personnel.

[0042] The pushing mechanism includes a drive groove 41 located at the top of the drawer groove 21. Two rotating rods 42 are rotatably mounted in the drive groove 41. Rotating rollers 44 are coaxially mounted on both rotating rods 42. The rotating rollers 44 on the two rotating rods 42 are connected by a push belt. A rotating motor 43 is installed in the drive groove 41. The drive shaft of the rotating motor 43 is coaxially mounted with one of the rotating rods 42. A push rail 52 is provided at the edge of the protective sleeve 51. The push rail 52 matches the push belt.

[0043] With the above technical features, during testing, the protective sleeve 51 of the test strip 50 is first torn off, so that the push rail 52 and the rotating roller 44 come into direct contact. Then, the rotating motor 43 drives the rotating rod 42 to rotate, the rotating rod 42 drives the rotating roller 44 to rotate, and the rotating roller 44 drives the push belt to rotate. The push belt first pushes the test strip 50 on the upper side out of the test strip slot 3. After the blood sample is collected, the rotating motor 43 drives the test strip 50 to move in the opposite direction until the test strip 50 is inserted into the slot 46 for testing. After the test is completed, the test strip 50 can be removed. This is more convenient when performing blood glucose and blood lipid tests.

[0044] Working principle:

[0045] The motor 37 drives two shafts 36 to rotate in opposite directions. The shafts 36, together with the connecting rod 47, drive the rotating shaft 18 to rotate. The rotating shaft 18 drives another rotating shaft 18 to rotate through the gear set 22. At the same time, the rotating shaft 18 drives the drive roller 20 to rotate, and the drive roller 20 drives the roller belt 17 to rotate. At this time, the roller belt 17 can tear the protective sleeve 51 covering the drive roller 20 to both sides and discharge it through the bag discharge hole 45, so that the push rail 52 and the rotating roller 44 are in direct contact. Then, the motor 43 drives the rotating rod 42 to rotate, the rotating rod 42 drives the rotating roller 44 to rotate, and the rotating roller 44 drives the push belt to rotate. The push belt first pushes the test strip 50 on the upper side to extend out of the test strip slot 3. After the blood sampling is completed, the motor 43 drives the test strip 50 to move in the opposite direction until the test strip 50 is inserted into the slot 46 for testing. After the test is completed, the test strip 50 can be removed.

[0046] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0047] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this invention.
