Description

Technical Field

[0001] This utility model relates to the field of blood glucose meter technology, and in particular to a test strip connection structure for a blood glucose meter. Background Technology

[0002] A blood glucose meter is a medical device used to measure the concentration of glucose in human blood and is widely used for daily monitoring by diabetic patients. When using it, a disposable test strip needs to be inserted into the test strip slot of the blood glucose meter so that the electrodes of the test strip make contact with the meter's detection circuitry to perform a blood glucose test.

[0003] A search revealed a utility model patent with authorization announcement number CN207586239U, which discloses a portable blood glucose meter, comprising a blood glucose meter body, a controller, an anti-slip rubber sleeve, and a test strip holder; the upper middle part of the surface of the blood glucose meter body is provided with a display screen, the lower middle part of the surface of the blood glucose meter body is provided with a public hole, the bottom surface of the blood glucose meter body is provided with a test strip insertion hole, the side wall of the test strip insertion hole is provided with a positioning slide, and a positioning component is provided in the positioning slide.

[0004] Traditional blood glucose meter test strip inserts typically use a fixed structure, where the test strip is held in place by elastic contacts or friction after insertion. However, this design has the following problems: 1. Some blood glucose meters rely solely on friction to hold the test strip in place, which may cause the test strip to loosen or fall off, affecting the measurement results; 2. After insertion, a significant portion of the test strip is exposed, which may deform due to external forces, such as touching or moving the blood glucose meter, affecting the stability of the test. Therefore, improvements are needed. Utility Model Content

[0005] This invention provides a test strip connection structure for a blood glucose meter, which solves the problem that some blood glucose meters rely solely on friction to fix the test strip, which may cause the test strip to loosen or fall off, affecting the measurement results. It also solves the problem that the test strip may deform due to external force after insertion, affecting the stability of the test.

[0006] To solve the above-mentioned technical problems, this utility model provides a test strip connection structure for a blood glucose meter, including a blood glucose meter body. A test strip insertion slot is fixedly connected to the bottom of the blood glucose meter body, and the position of the test strip insertion slot corresponds to that of the test strip insertion. Two sliding pins are slidably connected to the side wall of the test strip insertion slot, and the sliding pins penetrate the test strip insertion slot. A clamping plate is fixedly connected to one end of the sliding pin located inside the test strip insertion slot. A spring is sleeved on the outer side of the sliding pin. A fixing plate is fixedly connected to the bottom of the blood glucose meter body. A threaded rod is threadedly connected to the inside of the fixing plate, and the threaded rod penetrates the fixing plate. A frame is mounted on the end of the threaded rod via a bearing. The inner wall of the frame has an inclined surface, and the inclined surface of the frame abuts against the end of the sliding pin located outside the test strip insertion slot.

[0007] Preferably, one end of the spring is fixedly connected to the clamping plate, and the other end of the spring is fixedly connected to the inner wall of the test paper insertion slot expansion groove. The spring provides auxiliary repositioning for the clamping plate.

[0008] Preferably, a guide sleeve is fixedly connected to the clamp, and a guide pin is slidably connected inside the guide sleeve. The end of the guide pin is fixedly connected to the inner wall of the test paper insertion slot. The guide sleeve and guide pin provide guidance for adjusting the clamp.

[0009] Preferably, a knob is fixedly connected to the other end of the threaded rod, and the knob and the threaded rod are an integral structure. The knob facilitates the rotation of the threaded rod.

[0010] Preferably, a guide rod is fixedly connected to the frame, the guide rod passing through the fixed plate and slidably connected to the fixed plate. The guide rod guides the movement of the frame.

[0011] Preferably, a magnetic sleeve is fixedly connected to the bottom of the blood glucose meter body, a magnetic block is attracted inside the magnetic sleeve, a connecting frame is fixedly connected to the magnetic block, and a pad is fixedly connected to the end of the connecting frame, with the position of the pad corresponding to the position of the test strip insertion expansion slot. By setting the pad, the test strip inserted into the blood glucose meter body can be auxiliaryly supported, making it less prone to bending under force. At the same time, the pad is fixed by the magnetic attraction of the magnetic sleeve and the magnetic block, which is convenient for use.

[0012] Preferably, the connecting bracket is L-shaped and made of plastic. By setting the connecting bracket to an L-shape, the position of the pad and the test paper insertion expansion slot can be aligned.

[0013] Compared with related technologies, the test strip connection structure for a blood glucose meter provided by this utility model has the following advantages:

[0014] This utility model provides a test strip connection structure for a blood glucose meter. Through the coordinated design of a sliding pin, a clamping plate, and a spring, the test strip can be automatically clamped and released. When the knob is rotated, the threaded rod pushes the frame to move, and the inclined structure drives the sliding pin to slide, so that the clamping plate stably holds the test strip, ensuring accurate alignment when the test strip is inserted and improving the detection accuracy.

[0015] This utility model provides a test strip connection structure for a blood glucose meter. By setting a magnetic sleeve, a magnetic block, a connecting frame, and a pad at the bottom of the blood glucose meter body, the pad is fixed to the bottom of the blood glucose meter body by magnetic attraction and corresponds to the test strip insertion position of the blood glucose meter body. In this way, the test strip can be effectively supported after being inserted into the body, preventing the test strip from bending. Attached Figure Description
