Description

Technical Field

[0001] The utility model relates to the field of blood glucose meter equipment, in particular to a portable blood glucose meter. Background Art

[0002] A blood glucose meter is an electronic device used to measure the glucose (blood sugar) concentration in human blood. It usually consists of a small handheld instrument and a test strip (also called a test paper) for collecting blood samples. When using a blood glucose meter, you first need to collect a small drop of blood from your fingertips or other parts of your body. Then place the blood sample on the test strip and insert it into the blood glucose meter for analysis. The blood glucose meter will measure the glucose concentration in the blood through electrochemical methods or optical sensors and display the results on the screen. However, in the existing technology, when collecting blood, it is impossible to adjust the length of the needle. The length of the needle is directly related to the puncture depth. If the needle is too long, it may cause too deep a puncture, causing pain or discomfort. On the contrary, if the needle is too short, it may not be able to puncture to the required depth normally, and multiple attempts may be required to succeed, which brings inconvenience to the user.

[0003] The patent with application number 202322041745.X discloses a portable blood glucose meter, including a main body assembly, including a blood glucose meter, a display screen, a control button, a switch and a base. The display screen is fixed to one side of the blood glucose meter, the control button is located below the display screen, the switch is fixed to one side of the blood glucose meter, the base is fixed to the bottom of the blood glucose meter, and the adjustment assembly is arranged on the blood glucose meter, including a needle, an adjustment part, a rotating part and a storage part. The adjustment part is arranged on the top of the blood glucose meter, the rotating part is arranged on the adjustment part, and the storage part includes one side of the blood glucose meter. The arrangement of the entire assembly can adjust the length of the needle.

[0004] Although the above technical solution can adjust the length of the blood collection needle, it cannot replace the blood collection needle, which is prone to cross infection during use. In addition, the blood collection needle in the above technical solution needs to be manually inserted into the finger for blood collection, which will cause fear to the user during the blood collection process, and the slow insertion of the needle into the finger will cause the user's pain to increase. Utility Model Content

[0005] Based on this, the purpose of the present utility model is to provide a portable blood glucose meter to solve the technical problem that when replacing the blood collection needle, cross infection is easy to occur during use, and the slow insertion of the needle into the finger will cause the user's pain to increase.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a portable blood glucose meter, comprising a blood glucose meter body and a mounting hole provided at the top of the blood glucose meter body, a sliding rod embedded in the mounting hole, and a knob with an annular structure rotatably engaged with the side wall of the mounting hole, wherein a positioning groove is provided on the inner wall of the mounting hole, a positioning block elastically engaged with the positioning groove is provided on the sliding rod, and a needle seat is fixed to the side wall of the sliding rod, a micro-pain needle is damped and inserted in the needle seat, and a retaining ring is threadedly sleeved on the knob and abuts against the sliding rod.

[0007] The present invention is further configured such that heat dissipation grooves are provided at both ends of the blood glucose meter body, a display screen is provided at the top end of the side wall of the blood glucose meter body, and a plurality of buttons are installed at the bottom end of the side wall of the blood glucose meter body.

[0008] The present invention is further configured such that a squeezing block slidably inserted into a positioning groove is protruded from the top end of the blood glucose meter, and the bottom end of the squeezing block abuts against the positioning block.

[0009] The present invention is further configured such that a spring abutting against the sliding rod is embedded in the mounting hole, and a connecting rod is slidably inserted into the side wall of the blood glucose meter body.

[0010] The utility model is further configured such that a pull plate is fixed to one end of the connecting rod, and the other end of the connecting rod passes through a spring and is fixedly connected to the sliding rod.

[0011] The present invention is further configured such that an installation groove is provided on the outer wall of the slide rod, and the positioning block is embedded in the installation groove.

[0012] The present invention is further configured such that an elastic plate is embedded in the installation groove, and two ends of the elastic plate are fixedly connected to the bottom wall of the installation groove and the positioning block respectively.

[0013] The utility model is further configured such that a slot is provided on the top wall of the mounting hole, and a protrusion is provided on the outer wall of the retaining ring and is slidably inserted into the slot.

[0014] In summary, the present invention has the following beneficial effects: the present invention embeds a slide bar and a knob in the mounting hole at the top of the blood glucose meter body, fixes a needle seat embedded in the knob on the side wall of the slide bar, inserts the micro-pain needle into the needle seat with a damper, thereby keeping the micro-pain needle fixed, and facilitates the removal and replacement of the needle after the micro-pain needle is pulled out, thus avoiding cross infection caused by repeated use of needles;

[0015] The knob is connected by rotating the side wall of the mounting hole, and the knob drives the retaining ring to move laterally during the rotation process. The retaining ring maintains axial positioning by the protrusion inserted in the card slot. The hand-held pull plate drives the connecting rod and the sliding rod to contract through the connecting rod, and after contraction, the spring is squeezed to make the elastic plate push the positioning block to be inserted into the positioning slot, so that the sliding rod remains fixed, and the squeezing block is pressed to push the positioning block out of the positioning slot. The spring pushes the micro-pain needle on the sliding rod to contact the finger on the side wall of the knob to complete the blood collection, so that the micro-pain needle is instantly inserted into the finger, avoiding the pain caused by slow insertion. At the same time, the side wall of the sliding rod abuts against the retaining ring, and the extension length of the micro-pain needle and the blood collection depth are adjusted by adjusting the position of the retaining ring.
