[0002] A portable blood glucose tester is a small, portable device used to conveniently test a person's blood sugar level. It usually consists of a small blood glucose meter and a blood glucose test strip. The user can test by placing a small drop of blood on the test strip and then inserting the test strip into the blood glucose meter. The blood glucose meter will quickly analyze the glucose content in the blood and display a digital result of the blood glucose level. The small design of the portable blood glucose tester makes it easy to carry and can monitor blood sugar at any time. It is especially suitable for diabetic patients or people who need to closely monitor their blood sugar levels.

The plastic tube 41 is clamped inside the groove, and the slide groove 44 is provided on the inner walls of the left and right sides of the groove. A pressure spring 45 is fixedly installed on the top of the slide groove 44, and a lower pressure ring 46 is fixedly installed on the bottom end of the pressure spring 45. The fixing plate 43 and the rear end of the plastic tube 41 are adapted to abut against each other, and the fixing plate 43 limits the rear end of the plastic tube 41. The operator presses the needle 42 with his finger to remove blood, and the left and right sides of the lower pressure ring 46 are slidably connected to the inside of the slide groove 44, and the lower pressure ring 46 and the plastic tube 41 are adapted to be clamped, and the lower pressure ring 46 presses the plastic tube 41 downward to fix it inside the connecting block 3.
[0027] Reference Figure 3-Figure 6 The protection component 5 includes an inner groove 51 opened at the top of the front end of the plastic tube 41, a sliding block 52 is slidably connected inside the inner groove 51, a buffer spring 1 53 is fixedly installed at the bottom end of the sliding block 52, and a buffer spring 2 54 is fixedly installed at the rear end of the inner wall of the inner groove 51. A protective cover 55 is slidably connected to the surface of the front end of the plastic tube 41, and a slider 56 is fixedly installed on the inner wall of the top of the protective cover 55. The cross-sectional shape of the sliding block 52 is a "concave" shape. The front end of the sliding block 52 and the slider 56 are adapted to contact, and the rear end of the sliding block 52 extends to the top of the plastic tube 41. The operator can press the plastic tube 41 downward to keep it away from the slider 56. At this time, the slider 56 is no longer moved by the sliding block 52. Limiting, buffer spring 1 53 is vertically arranged, the bottom end of buffer spring 1 53 is fixedly installed on the bottom wall of inner groove 51, buffer spring 2 54 is horizontally arranged, the front end of buffer spring 2 54 is fixedly installed on the rear end face of slider 56, slider 56 is slidably connected to the inside of inner groove 51, a cylindrical groove 57 is opened at the front end of protective cover 55, a card block 58 is fixedly installed on the inner wall of cylindrical groove 57, the inner diameter of cylindrical groove 57 is larger than the diameter of needle 42, there are four card blocks 58 and they are circumferentially distributed inside cylindrical groove 57, the operator can place alcohol tissue between card block 58 and the inner wall of cylindrical groove 57, at this time, moving protective cover 55 will make the alcohol tissue wipe and disinfect needle 42.
[0028] Working principle: the operator first pulls the lower pressure ring 46 upwards, so that the lower pressure ring 46 compresses the pressure spring 45 and moves upwards, and then inserts the plastic tube 41 into the inside of the groove. At this time, the operator loosens the lower pressure ring 46 again, so that the lower pressure ring 46 moves downward under the action of the rebound force of the pressure spring 45 until it abuts against the top of the plastic tube 41. At this time, the lower pressure ring 46 fixes the plastic tube 41 inside the groove. At this time, the operator pushes the plastic tube 41 backwards, so that the rear end of the plastic tube 41 abuts against the end face of the fixing plate 43. At this time, the operation of installing the plastic tube 41 on the surface of the connecting block 3 is completed.
[0029] When the operator needs to test blood sugar, first clamp the disinfectant alcohol tissue between the clamping block 58 and the inner wall of the cylindrical groove 57, and at this time the rear end of the slider 56 abuts against the front end of the slider 52, and then the operator presses the rear end of the slider 52 downward. At this time, the slider 52 is pressed downward and compresses the buffer spring 53, so that the front end of the slider 52 is separated from the slider 56. At this time, the rear end of the protective cover 55 is no longer limited, and the operator presses the protective cover 55 backward with his finger, and the protective cover 55 will drive the slider 56 to slide backward inside the inner groove 51 until the cylindrical groove 57 moves close to the needle 42, and then the needle 42 extends to the outside of the protective cover 55. The operator touches the front end of the needle 42 with his finger to pierce the finger, and then removes the test strip 2 to drop blood on the surface of the test strip 2, and then inserts the test strip 2 into the inside of the device body 1, and then opens the device body 1 for blood sugar testing.
