Description

Technical Field

[0001] The present invention relates to the technical field of blood glucose testers, in particular to a blood glucose tester. Background Art

[0002] With the dietary culture of modern people, a large proportion of the population suffers from "three highs", which endangers their health. For this reason, professionals have developed testing equipment, among which blood glucose tester is one of them. The equipment can effectively test blood glucose, so as to develop reasonable eating habits.

[0003] However, when the blood glucose tester is in use, the test strip needs to be manually aligned with the plug-in port, which takes a certain amount of time. When inserting the test strip into the blood glucose tester, if the connection with the contact head is unstable during internal insertion, poor contact may occur during testing, resulting in errors in the test results. At the same time, because the plug-in port of the blood glucose tester is always exposed to the outside, if foreign matter enters the inside, the contact head may be blocked when the test strip is plugged in, which makes cleaning more troublesome.

[0004] Therefore, the demand for high-reliability products is imminent, so we have proposed a blood glucose tester that facilitates the insertion of test strips and prevents incomplete insertion of the test strips into the socket, which causes errors in the test. At the same time, when inserting the test strips, the differential connections are automatically cleaned to prevent clogging by foreign objects. Summary of the invention

At the same time, when the test strip is inserted, the differential connection is automatically cleaned to prevent clogging by foreign objects. This solves the problem that when the blood glucose tester is in use, the test strip needs to be manually aligned with the plug-in interface, which takes a certain amount of time. When inserting the blood glucose tester, if the connection with the contact head is unstable during internal insertion, poor contact may occur during testing, resulting in errors in the test results. At the same time, because the plug-in interface of the blood glucose tester is always exposed to the outside, if foreign objects enter the inside, the contact head may be easily blocked when the test strip is inserted, and cleaning is also more troublesome.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a blood glucose tester having the following beneficial effects:

[0019] 1. The blood glucose tester moves upward through the bending plate, and a small gap is left between the two bending plates.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The blood glucose tester comprises a shell 1, a starting mechanism 2 is movably connected inside the shell 1, a connecting rod 3 is fixedly connected to the top of the starting mechanism 2, a conveying mechanism 4 is fixedly connected to the right end of the connecting rod 3, an injection mechanism 5 is fixedly connected to the bottom of the starting mechanism 2, a mounting block 6 is fixedly connected to the right end of the injection mechanism 5, an air hole 7 is opened inside the mounting block 6, and a plug connector 8 is fixedly connected to the bottom of the mounting block 6.

[0031] Furthermore, the starting mechanism 2 includes a movable plate 21, and the movable plate 21 is movably connected to a guide rod 22 on one side close to the conveying mechanism 4, the bottom of the movable plate 21 is fixedly connected to a support rod 23, the bottom of the support rod 23 is fixedly connected to a movable block 24, and the top of the movable block 24 is fixedly connected to a tension spring 25.

[0032] Furthermore, the conveying mechanism 4 includes a slider 41 inside, and the slider 41 is movably connected to a movable rod 42 at one end away from the connecting rod 3, and the movable rod 42 is movably connected to a gear 43 at a side away from the connecting rod 3, and the gear 43 is movably connected to a rack 44 at a side away from the movable rod 42, and the rack 44 is fixedly connected to a bent plate 45 at a side away from the gear 43, and a track 46 is provided at the rear end of the bent plate 45 and located inside the shell 1, and a guide block 47 is fixedly connected to the upper end of the track 46, and a limiting block 48 is fixedly connected to the side of the guide block 47 away from the track 46.

[0033] The movable rod 42 has a driving force on the gear 43, which makes the gear 43 rotate. As the gear 43 rotates, the toothed teeth engage, thereby driving the rack 44 to move upward. Due to the positioning connection relationship between the rack 44 and the bent plate 45, the bent plate 45 is driven to move upward together, so that the bent plate 45 moves along the trajectory of the track 46. As the bent plate 45 moves upward, a small gap is left between the two bent plates 45. At this time, the taken out test strip is placed in the upper end of the guide block 47. Due to the baffle effect of the limit block 48, the test strip slides between the two bent plates 45. As the movable plate 21 is released, the bent plate 45 moves downward along the trajectory of the track 46 through the connection relationship of the internal structure. Because the right end of the bent plate 45 is made of rubber material, the test strip is also driven downward by friction, thereby driving the test strip to be inserted into the inside of the plug connector 8, thereby facilitating the insertion of the test strip and preventing the test strip from being incompletely plugged into the socket, resulting in an error in the test.

[0034] Embodiment 2:

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The blood glucose tester comprises a shell 1, a starting mechanism 2 is movably connected inside the shell 1, a connecting rod 3 is fixedly connected to the top of the starting mechanism 2, a conveying mechanism 4 is fixedly connected to the right end of the connecting rod 3, an injection mechanism 5 is fixedly connected to the bottom of the starting mechanism 2, a mounting block 6 is fixedly connected to the right end of the injection mechanism 5, an air hole 7 is opened inside the mounting block 6, and a plug connector 8 is fixedly connected to the bottom of the mounting block 6.

[0036] Furthermore, the starting mechanism 2 includes a movable plate 21, and the movable plate 21 is movably connected to a guide rod 22 on one side close to the conveying mechanism 4, the bottom of the movable plate 21 is fixedly connected to a support rod 23, the bottom of the support rod 23 is fixedly connected to a movable block 24, and the top of the movable block 24 is fixedly connected to a tension spring 25.

[0037] Furthermore, the jet mechanism 5 includes a fixed rod 51 inside, a driving rod 52 is hinged at the bottom of the fixed rod 51, a receiving rod 53 is hinged on the side of the driving rod 52 away from the fixed rod 51, an extrusion block 54 is fixedly connected to the side of the receiving rod 53 away from the driving rod 52, a return spring 55 is fixedly connected to the side of the extrusion block 54 close to the receiving rod 53, an empty box 56 is movably connected to the side of the extrusion block 54 away from the receiving rod 53, and a fixed plate 57 is fixedly connected to the side of the empty box 56 away from the return spring 55.

[0038] When the moving block 24 moves downward, it drives the fixed rod 51 to move downward together, and then there is a thrust on the end of the driving rod 52. Because the driving rod 52 is an inclined rod and the driving rod 52 is connected to the receiving rod 53, the receiving rod 53 moves to the side close to the plug connector 8, and drives the extrusion block 54 to move together, so that the extrusion block 54 has an extrusion force on the empty box 56, so that the inside of the empty box 56 is compressed, and the gas inside the empty box 56 is connected through the internal pipeline, so that the upper end of the air hole 7 is sprayed, so as to clean the upper end of the plug connector 8, so as to achieve the effect of automatically cleaning the differential connection when the test strip is plugged in to prevent clogging by foreign matter.

The side of the connecting rod 3 close to the movable rod 42 is fixedly connected to the net side of the slider 41 close to the connecting rod 3. The top of the moving block 24 is fixedly connected to a tension spring 25.

[0042] Please refer to 4. The conveying mechanism 4 includes a slider 41 inside. The end of the slider 41 away from the connecting rod 3 is movably connected to a movable rod 42. The side of the movable rod 42 away from the connecting rod 3 is movably connected to a gear 43. The side of the gear 43 away from the movable rod 42 is movably connected to a rack 44. The side of the rack 44 away from the gear 43 is fixedly connected to a bent plate 45. The side of the bent plate 45 away from the rack 44 is made of rubber material. A card block is fixedly installed at the rear end of the rack 44, and the card block is located inside a track 46. A track 46 is opened at the rear end of the bent plate 45 and located inside the shell 1. The upper end of the track 46 is fixedly connected to a guide block 47. The side of the guide block 47 away from the track 46 is fixedly connected to a limiting block 48.

[0043] Please refer to 5. The jet mechanism 5 includes a fixed rod 51 inside. A driving rod 52 is hinged at the bottom of the fixed rod 51. A receiving rod 53 is hinged on the side of the driving rod 52 away from the fixed rod 51. A squeezing block 54 is fixedly connected to the side of the receiving rod 53 away from the driving rod 52. A pressing block is fixedly installed on the side of the squeezing block 54 away from the receiving rod 53. The pressing block is located inside the empty box 56. The interior of the empty box 56 is connected with the interior of the air hole 7. A return spring 55 is fixedly connected to the side of the squeezing block 54 close to the receiving rod 53. The side of the squeezing block 54 away from the receiving rod 53 is movably connected to the empty box 56. The side of the empty box 56 away from the returning spring 55 is fixedly connected to a fixing plate 57.

[0044] Working principle: when measurement is required, the connecting rod 3 is pushed downward, so that the connecting rod 3 moves downward along both sides of the housing 1, thereby exerting a downward pressure on the support rod 23, causing the support rod 23 to move downward, thereby driving the moving block 24 to move downward together, and then exerting a downward pulling force on the tension spring 25, causing the tension spring 25 to be stretched internally, thereby accumulating elastic potential energy internally to prepare for the reset of the moving block 24. At the same time, when the moving block 24 moves downward, it drives the connecting rod 3 to move downward together. Due to the connection relationship between the sliders 41 and 31, the slider 41 also moves downward, thereby exerting a driving force on the gear 43 through the movable rod 42, causing the gear 43 to rotate. As the gear 43 rotates, the gear teeth are engaged with each other, thereby driving the rack 44 to move downward. The rack 44 and the bent plate 45 are positioned and connected, thereby driving the bent plate 45 to move upward, so that the bent plate 45 moves along the track of the track 46. As the bent plate 45 moves upward, a small gap is left between the two bent plates 45. At this time, the taken out test strip is placed in the upper end of the guide block 47. Due to the baffle effect of the limit block 48, the test strip slides between the two bent plates 45. As the movable plate 21 is released, the bent plate 45 moves downward along the track of the track 46 through the connection relationship of the internal structure. Because the right end of the bent plate 45 is made of rubber material, the friction force drives the test strip to move downward as well, thereby driving the test strip to be inserted into the inside of the plug connector 8, thereby facilitating the insertion of the test strip and preventing the test strip from being incompletely connected to the socket, resulting in an error in the test.

[0045] At the same time, when the moving block 24 moves downward, it drives the fixed rod 51 to move downward together, and then there is a thrust on the end of the driving rod 52. Because the driving rod 52 is an inclined rod, and the driving rod 52 is connected to the receiving rod 53, the receiving rod 53 moves to the side close to the plug connector 8, and drives the extrusion block 54 to move together, so that the extrusion block 54 has an extrusion force on the empty box 56, so that the inside of the empty box 56 is compressed, and the gas inside the empty box 56 is connected through the internal pipeline, so that the upper end of the air hole 7 is sprayed, so as to clean the upper end of the plug connector 8, so as to achieve the effect of automatically cleaning the differential connection when the test strip is plugged in to prevent clogging by foreign matter.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
