Technical Field
[0001] This utility model relates to the field of blood glucose meter technology, specifically a portable blood glucose meter. Background Technology
[0002] A portable blood glucose meter is a small medical device that can quickly detect the concentration of glucose in the blood. It is mainly used for daily blood glucose monitoring by diabetic patients, and is also suitable for blood glucose screening in healthy individuals. With changes in people's lifestyles, the incidence of diabetes is rising year by year. Patients need to monitor their blood glucose regularly to adjust their diet, medication, and exercise plans to avoid complications caused by excessively high or low blood glucose levels. Traditional blood glucose testing requires going to the hospital and relies on large testing instruments, which has problems such as long testing cycles and cumbersome procedures. It cannot meet the needs of patients for real-time monitoring and timely adjustment of health plans. Therefore, portable blood glucose meters that can perform blood glucose testing anytime and anywhere have become a market necessity, providing users with a convenient and efficient blood glucose monitoring solution. Traditional blood glucose testing technologies have many shortcomings, seriously affecting user experience and testing results. On the one hand, traditional testing devices are bulky and inconvenient to carry, making it difficult for users to monitor their blood glucose levels when out and about, resulting in undetected blood glucose fluctuations and potentially delaying disease control. On the other hand, test strips and blood collection components of traditional devices are often stored separately, making the process complicated and lacking effective protective structures. Test strips are susceptible to moisture and contamination, affecting testing accuracy, and blood collection components are easily damaged or pose safety hazards. In addition, the operation steps of traditional devices are cumbersome and not user-friendly for elderly users or those with weaker operational skills, increasing the difficulty of blood glucose monitoring and failing to meet users' needs for convenient and accurate blood glucose testing. Therefore, we propose a portable blood glucose meter. Utility Model Content

The top end is connected to a hinge block that can rotate, and the end end has a positioning groove 15 for installing the blood-sticking needle 8. It can be rotated out to a suitable blood collection angle. Blood-drawing needle 8: The positioning groove 15 of the needle head fixing rod 7 is inserted at the top, and the outer wall is attached to the rubber block 11 for blood collection. Under the action of the fixing component, it will not loosen during blood collection.

The third groove 16 is distributed in a ring at the bottom of the needle fixing rod 7, and is equipped with a locking block 9 and a second spring 10 inside. It provides a track for the sliding of the locking block 9 and helps to fix the blood-piercing needle 8. Rubber groove 17: Symmetrically distributed inside the third sliding groove 16, connected to the positioning groove 15, for placing the rubber block 11, providing space for the rubber block 11 to fit the lancet 8.
[0027] Working Principle: In the test strip dispensing stage, the test strip storage box 6 is the core component for storing the test strips. It is fixed in the placement slot inside the right end of the detector body 1 by an installation assembly. The upper and lower ends of the test strip storage box 6 have symmetrically distributed second sliding grooves 14. Each second sliding groove 14 has a mounting positioning block 3 slidably installed inside it. The end of the mounting positioning block 3 is connected to a symmetrically distributed first spring 4, which is fixed inside the second sliding groove 14. When the test strip storage box 6 is installed into the placement slot at the right end of the detector body 1, the front end of the mounting positioning block 3 will be inserted into the mounting holes at the upper and lower ends of the placement slot under the elastic force of the first spring 4. The test strip storage box 6 is fixed in place by the mounting positioning block 3. Inside the right end of the instrument body 1, when it is necessary to remove the test strip, the fixing of the detector cover 2 must first be released. The detector cover 2 has symmetrically distributed first sliding grooves 13 at its upper and lower ends, and an installation positioning block 3 with a first spring 4 is also installed inside. By pressing the installation positioning block 3 to compress the first spring 4 and disengage it from the installation hole, the fixing of the detector cover 2 can be released. Since the fixing blocks on both sides of the front end of the test strip storage box 6 are rotatably connected to one end of the telescopic connecting rod 5, and the other end of the telescopic connecting rod 5 slides with the guide rod in the connecting groove 12 of the detector cover 2 through the internal telescopic sliding groove, after the fixing of the detector cover 2 is released, when the right end of the detector cover 2 is pulled outward, the telescopic connecting rod 5 will slide along the guide rod in the telescopic sliding groove, and at the same time surround the test strip storage box. When the connecting rod of box 6 rotates, the test strip can be directly removed from the test strip storage box 6 to complete the test strip retrieval operation. In the blood collection preparation stage, when the needle fixing rod 7 needs to be used, first release the fixation of the left end detector cover plate 2 in the same way as the right end. Press the mounting positioning block 3 in the first sliding groove 13 of the left end detector cover plate 2 to compress the first spring 4 so that it is disengaged from the mounting hole. Then open the left end detector cover plate 2. The placement groove inside the left end of the detector body 1 is provided with a hinge block. The connecting post at the top of the needle fixing rod 7 is rotatably engaged with the hinge block. Therefore, after opening the left end detector cover plate 2, rotating the needle fixing rod 7 will rotate the needle fixing rod 7 out of the placement groove to a suitable blood collection angle. The end of the needle fixing rod 7 is provided with a positioning groove 1. 5. Multiple annularly distributed third sliding grooves 16 are provided at the bottom. Each third sliding groove 16 has a rubber groove 17 communicating with the positioning groove 15 on its inner side. A locking block 9 is slidably installed inside the third sliding groove 16. The bottom end of the locking block 9 is connected to a second spring 10, and the back is provided with an inclined rubber block 11 located in the rubber groove 17. When the tip of the lancet 8 is inserted into the positioning groove 15, the locking block 9, under the elastic force of the second spring 10, will tightly fit the inclined rubber block 11 at the front end with the outer wall of the lancet 8. The lancet 8 is firmly fixed through the elastic clamping structure, ensuring that the lancet 8 will not loosen during blood collection. The placement grooves at both ends of the detector body 1 provide installation space for each component, and the mounting holes at the top and bottom ends serve as positioning references.Whether it's the test strip storage box 6 being fixed to the right-end slot via the insertion and engagement of the mounting positioning block 3 with the mounting hole, or the two detector cover plates 2 being fixed to both ends of the detector body 1 via their own mounting positioning blocks 3 engaging with the corresponding mounting holes, or the needle fixing rod 7 being rotated via a hinge block, all these methods utilize mounting and fixing components to ensure the stability of each component in the non-operational state. Simultaneously, they allow for easy release of the fixings when operation is required, enabling actions such as test strip retrieval and needle rotation, ultimately achieving the efficient and convenient use required for a portable blood glucose meter.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
