Description

Technical Field

[0001] This utility model relates to the field of blood glucose meter technology, and in particular to a blood glucose meter that is easy to operate. Background Technology

[0002] Blood glucose monitoring is an important part of the daily management of diabetic patients. Traditional blood glucose meters usually require separate lancing devices and test strips, and the operation steps are cumbersome.

[0003] A search revealed a utility model patent with authorization announcement number CN104142402B, which discloses a blood glucose meter. The blood glucose meter includes a microprocessor, a test strip insertion port, and a calibration device. The test strip insertion port is used to insert a test strip, the calibration device is used to collect calibration code information from the test strip, and the microprocessor is used to provide corresponding current compensation based on the calibration code collected by the calibration device.

[0004] In existing technologies, some blood glucose meters' lancets cannot be fully retracted, making them prone to loosening or scratching users during transport and causing inconvenience. Furthermore, traditional lancets have a fixed puncture depth, which cannot accommodate the skin thickness of different individuals, potentially leading to difficulty in blood collection or increased pain. Therefore, improvements are needed. Utility Model Content

[0005] This invention provides a convenient blood glucose meter that solves the problem that some blood glucose meters cannot be fully stored, making them easy to loosen or scratch users when carried, and causing inconvenience in operation. It also solves the problem that the puncture depth of traditional puncture needles is fixed and cannot adapt to the skin thickness of different people, which may lead to difficulty in blood collection or increased pain.

[0006] To solve the above-mentioned technical problems, this utility model provides a convenient blood glucose meter, including a blood glucose meter body. A storage slot is fixedly connected to the left side of the blood glucose meter body. A lancet housing is slidably connected inside the storage slot. The lancet housing has an adjustable sampling depth mechanism inside. A slider is fixedly connected to the outer wall of the lancet housing. The slider passes through the storage slot and is slidably connected to the storage slot. A positioning block is fixedly connected to the top of the lancet housing. A positioning post is fixedly connected to the top inner side of the storage slot. The positioning post is engaged with the positioning block.

[0007] Preferably, the storage slot has an internal cavity, and the blood collection needle housing is located within the cavity. The blood collection needle housing can extend and retract within the cavity of the storage slot.

[0008] Preferably, a knob is fixedly connected to the end of the slider, and the knob is slidably connected to the outer wall of the receiving groove. The knob facilitates the control of the sliding block to move the blood collection needle housing in and out of the receiving groove.

[0009] Preferably, a locking pin is slidably connected to the inner wall of the positioning post, and the locking pin engages with the positioning block. A spring is provided inside the positioning post, with one end of the spring fixedly connected to the locking pin and the other end of the spring fixedly connected to the inner surface of the positioning post. The spring force can act on the locking pin, causing the locking pin to engage with the positioning block, thereby increasing the stability of the blood collection needle housing when stored in the storage slot.

[0010] Preferably, the blood sampling depth adjustable mechanism includes a fixing plate fixedly connected to the inside of the blood sampling needle housing. An adjusting rod is mounted inside the fixing plate via a bearing. An adjusting sleeve is threadedly connected to the lower section of the adjusting rod. A threaded head is fixedly connected to the lower end of the adjusting sleeve. A needle is threadedly connected to the outside of the threaded head. The needle penetrates the blood sampling needle housing and is slidably connected to it. A knob is fixedly connected to the top of the adjusting rod and is rotatably connected to the inside of the blood sampling needle housing. The adjustable blood sampling depth mechanism facilitates control of the length of the needle extending from the blood sampling needle housing, allowing the user to stably control the blood sampling depth and simplifying operation.

[0011] Preferably, the side wall of the blood collection needle housing has a groove, and the position of the groove corresponds to the position of the knob. The groove facilitates the rotation of the knob.

[0012] Preferably, a guide pin is fixedly connected to the outer side of the adjusting sleeve, and a guide groove is fixedly connected to the inner wall of the blood collection needle housing. The guide pin and the guide groove are slidably connected. The guide pin and the guide groove guide the axial movement of the adjusting sleeve on the adjusting rod.

[0013] Compared with related technologies, the blood glucose meter provided by this utility model, which is easy to operate, has the following advantages:

[0014] This utility model provides a convenient blood glucose meter. By setting a storage slot on the left side of the blood glucose meter body, the blood collection needle housing is located in the storage slot. The slider and the knob realize the rapid extension and retraction of the blood collection needle housing, which is convenient to carry and avoids the needle tip being exposed. In this way, the spring-locking structure of the positioning post and the locking pin ensures that it is stable when stored and prevents accidental slippage.

[0015] This invention provides a convenient blood glucose meter. By setting an adjustable blood sampling depth mechanism inside the blood sampling needle housing, the adjustable blood sampling depth mechanism can achieve needle extension and retraction by rotating the adjustment rod with the adjustment sleeve. Users can accurately control the blood sampling depth, reduce pain, and the operation is simple and convenient. Attached Figure Description
