Description

Technical Field

[0001] This utility model relates to the field of blood glucose meter technology, and in particular to a blood glucose meter with an easy-to-replace needle. Background Technology

[0002] Blood glucose meters assist in diabetes management by detecting the concentration of glucose in the blood. They are mainly divided into two types: photoelectric and electrode. Photoelectric meters calculate blood glucose values ​​by measuring the intensity of reflected light from changes in the color of the test strip, but are easily affected by ambient light or test strip contamination. Electrode meters, on the other hand, use an electrochemical method to detect the reaction current, resulting in smaller errors (±0.5), stronger anti-interference capabilities, and no need for frequent calibration.

[0003] The utility model patent with patent authorization announcement number CN213640872U discloses an electronic blood glucose meter, which includes an electronic blood glucose meter body, test strips, a display screen and buttons. The upper side wall of the electronic blood glucose meter body has a test strip slot, in which test strips are inserted. The right side wall of the electronic blood glucose meter body is provided with an arc-shaped mounting plate, and a blood collection needle is fixedly connected to the arc-shaped mounting plate through a connecting device. The blood collection needle includes a needle rod and a needle sleeve. The lower end of the outer side wall of the needle rod has an external thread, and a needle tip is fixedly connected to the lower side wall of the needle rod. The upper end of the inner side wall of the needle sleeve has an internal thread.

[0004] However, existing blood glucose meters also have certain shortcomings. Most current blood glucose meters require the use of needles to absorb and process blood. Since needles are often fixed in place using bolts or threads, and the disassembly and assembly of these threads and bolts require specialized tools, this is undoubtedly inconvenient for replacement. Therefore, improvements are needed. Utility Model Content

[0005] This invention provides a blood glucose meter with an easy-to-replace needle, solving the problem that existing blood glucose meters are mostly used with needles to absorb and detect blood. Since the needles are mostly fixed by bolts or threads, the disassembly and assembly of threads and bolts require professional operating tools, making it inconvenient to replace and use them.

[0006] To solve the above-mentioned technical problems, this utility model provides a blood glucose meter with easy needle replacement, including a blood glucose meter body. The front of the blood glucose meter body is provided with control buttons, and a display screen is provided on the front of the blood glucose meter body above the control buttons. Multiple evenly distributed friction grooves are formed on the side of the blood glucose meter body. An installation head is provided on the inner wall of the blood glucose meter body, and a needle body is slidably connected to the inner wall of the installation head. A replacement mechanism is provided on the blood glucose meter body. A support screw is fixedly connected to the front of the blood glucose meter body above the display screen, and a protective plate is rotatably sleeved on the outer side of the support screw, with the protective plate in contact with the blood glucose meter body.

[0007] Preferably, a screw cylinder is threadedly connected to the outer side of the support screw, and a pressing plate is fixedly connected to the back of the screw cylinder. The pressing plate is movably connected to the support screw and contacts the protective sheet. Through the cooperation of the pressing plate and the screw cylinder, the protective sheet can be pressed and fixed.

[0008] Preferably, the protective sheet has multiple friction patterns on its front side, and these friction patterns are evenly distributed on the protective sheet. By setting the friction patterns, the friction contact effect on the surface of the protective sheet can be improved.

[0009] Preferably, a limiting plate is fixedly connected to the front of the supporting screw. The limiting plate is made of rubber, and the screw cylinder can be moved and limited by the setting of the limiting plate.

[0010] Preferably, a counterweight is fixedly connected to the inner wall of the protective plate. The counterweight is made of stainless steel. The setting of the counterweight can ensure the deflection effect of the protective plate.

[0011] Preferably, the replacement mechanism includes a fixing frame, which is fixedly connected to the inner wall of the blood glucose meter body. A rod is slidably connected to the vertical part of the fixing frame. The rod is slidably connected to the needle body. A guide block is fixedly connected to the lower side of the rod. An end is fixedly connected to the end face of the rod away from the needle body. A spring is welded to the end face of the end face near the needle body. The other end of the spring is welded to the vertical part of the fixing frame. Through the cooperation of the spring, the rod, and other structures, the needle body can be inserted and limited.

[0012] Preferably, the guide block contacts the needle body and is slidably connected to the vertical part of the fixing frame. The guide block can guide the movement of the insertion rod.

[0013] Compared with related technologies, the blood glucose meter provided by this utility model, which facilitates needle replacement, has the following beneficial effects:

[0014] This invention provides a blood glucose meter that facilitates needle replacement. By pulling the tip away from the needle body, the insertion rod slides along the vertical part of the fixing frame. Under the action of the guide block, the insertion rod is kept in a stable moving state, and finally the insertion rod is detached from the needle body, allowing for quick disassembly and replacement of the needle body.

[0015] This invention provides a blood glucose meter that facilitates needle replacement. By pushing the screw cylinder to rotate counterclockwise, the screw cylinder can move towards the limiting plate due to the threaded connection, thereby causing the squeezing plate to disengage from the protective plate. Under the action of the counterweight, the two protective plates can be deflected and contacted from top to bottom, shielding and protecting the display screen and preventing accidental impact damage to the blood glucose meter display screen when idle.
