[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-5 The glycated hemoglobin measuring instrument shown in the figure comprises a glycated hemoglobin measuring instrument body 1, a display screen 104 is provided on the top of the glycated hemoglobin measuring instrument body 1, an operating table 5 fixed to the top of the glycated hemoglobin measuring instrument body 1 is provided on the rear side of the display screen 104, and a magnifying camera 9 facing the operating table 5 is fixed on the rear side of the display screen 104;

[0035] A control panel 103 is fixedly provided on the front side of the glycated hemoglobin measuring instrument body 1, a detection cabin 101 is provided on the top of the glycated hemoglobin measuring instrument body 1, and a cover plate 102 hinged on the top of the glycated hemoglobin measuring instrument body 1 is provided on the top of the detection cabin 101. During the test, the test paper card with the mixed solution added is placed inside the detection cabin 101, and the detection cabin 101 is closed by the cover plate 102;

[0036] A connecting bracket 10 for adjusting the angle of a display screen 104 is provided at the top of the glycated hemoglobin meter body 1. The display screen 104 is movably connected to the glycated hemoglobin meter body 1 via the connecting bracket 10. Two lighting lamps 8 are fixedly provided on the rear side of the display screen 104, and the lighting lamps 8 can provide illumination in dim conditions.

[0037] Before officially using the glycated hemoglobin measuring instrument body 1 to measure glycated hemoglobin, preparation work is required. First, a blood sample is collected, and the sample is mixed with a reagent, and the mixed liquid is dripped onto a test paper card. These operations can be performed on the top of the operating table 5. During the operation, the magnifying camera 9 on the back side of the display screen 104 is turned on, and the operation situation on the top of the operating table 5 is photographed by the magnifying camera 9, and the photographed picture is magnified and displayed on the display screen 104 in real time. Since the test paper cards and other instruments involved in the above operation are relatively small in size, it is inconvenient to observe them with the naked eye during operation. By taking pictures with the magnifying camera 9 and magnifying them using the display screen 104, more detailed observation can be performed during the operation, making the operation more convenient.

[0038] The last step of the operation is to drop the mixture of the reagent and the blood sample onto the test paper card, then place the test paper card inside the detection chamber 101 for detection, and display the final test results on the display screen 104. In addition, the glycated hemoglobin measuring instrument body 1 can also be connected to a computer, a printer and other equipment to input the test results into a database for storage or directly print them out.

[0039] When adding the mixed liquid, you need to ensure accuracy and avoid leakage of the mixed liquid, such as Figure 1-5 As shown, a detachable mounting seat 3 is provided at the top of the operating table 5, a vertical plate 4 is fixedly provided at the top of the mounting seat 3, a dripping assembly 7 is provided at the front side of the vertical plate 4, and the dripping assembly 7 includes an adjustment block 701 connected to the front side of the vertical plate 4 through a damping bearing, and a test paper card fixing piece 702 for placing a reagent card is fixedly provided at the front side of the adjustment block 701;

[0040] A reagent bottle fixing piece 704 is provided at the bottom of the test paper card fixing piece 702, and two elastic clips 705 are fixedly provided at the top of the reagent bottle fixing piece 704. A reagent bottle 2 is provided at the top of the reagent bottle fixing piece 704, and the lower half of the reagent bottle 2 is clamped between the two clips 705. The reagent bottle 2 clamped and fixed by the clips 705 can be aligned with the dripping port of the test paper card on the test paper card fixing piece 702;

[0041] The bottom end of the adjusting block 701 is provided with two insertion holes 706 , and the two insertion holes 706 are provided with guide rods 703 inside. The bottom end of the guide rod 703 extends to the bottom of the adjusting block 701 and is fixedly connected to the reagent bottle fixing plate 704 .

[0042] The top of the adjustment block 701 is provided with two balancing channels which are respectively connected to the inside of the two sockets 706 to balance the air pressure inside and outside the sockets 706. A friction pad 707 which contacts the outer end of the guide rod 703 is fixedly provided on the inner wall of the socket 706, so that the sliding of the guide rod 703 has resistance and the guide rod 703 can have a hovering function. The bottom end of the test paper card fixing piece 702 is fixedly provided with a frame which matches the contour of the test paper card, and the test paper card can be clamped at the bottom end of the test paper card fixing piece 702 by using the frame.

[0043] The blood sample and the detection reagent are mixed evenly in the reagent bottle 2 to form a mixed solution, and then the pure test paper card is fixed to the bottom of the test paper card fixing piece 702 through the frame on the test paper card fixing piece 702, and then the reagent bottle 2 storing the mixed solution is fixed to the top of the reagent bottle fixing piece 704 through the clamping piece 705. The positions of the clamping piece 705 and the frame are pre-set, so that the reagent bottle 2 and the test paper card will automatically align with each other after the two are fixed, and the extrusion port of the mixed solution on the reagent bottle 2 is facing the test paper card. The dripping port of the paper card, the next step is to push the reagent bottle fixing piece 704 upward and make the guide rod 703 slide in the insertion hole 706, driving the reagent bottle 2 to move upward, so that the extrusion port on the reagent bottle 2 can be accurately docked with the dripping port of the test paper card. After the two are docked, rotate the adjustment block 701 to rotate the dripping assembly 7 by 180° as a whole, and rotate the reagent bottle 2 originally with the bottle mouth facing upward to the bottle mouth facing downward. Finally, squeeze the reagent bottle 2 and squeeze the mixed liquid into the dripping port, so that the mixed liquid can be dripped on the test paper card;

[0044] This method can accurately dock the extrusion port on the reagent bottle 2 with the dripping port of the test paper card, and during the docking process, the extrusion port of the reagent bottle 2 faces upward, which greatly reduces the risk of mixed liquid leakage and improves the success rate of the operation.

[0045] The blood sample and the reagent are mixed inside the reagent bottle 2, such as Figure 3 , 6 As shown in , 8, the reagent bottle 2 includes an elastic bottle body 201 filled with a liquid reagent, a transparent bottle bottom 202 is fixedly provided at the bottom end of the elastic bottle body 201, an extrusion nozzle 203 is provided at the bottle mouth of the elastic bottle body 201 through a thread, the extrusion nozzle 203 is directed downward, and the elastic bottle body 201 is squeezed to squeeze out the mixed liquid, and a closing cap 204 is provided at the top of the extrusion nozzle 203 through a snap-fit ​​sleeve, and when separating the extrusion nozzle 203 and the closing cap 204, a little force is required to pull the closing cap 204 off the extrusion nozzle 203.

[0046] The main body of the reagent bottle 2 is composed of an elastic bottle body 201, and the transparent bottle bottom 202 is used to enable the mixing of the blood sample and the reagent inside the elastic bottle body 201 to be clearly seen from the bottom of the reagent bottle 2. The reagent is originally stored in the elastic bottle body 201. When adding the blood sample, the extrusion nozzle 203 is removed, and the blood sample is added through the opening of the elastic bottle body 201. Then, the extrusion nozzle 203 is installed at the opening of the elastic bottle body 201 through a thread to close the elastic bottle body 201. When the mixed liquid is dripped, the closing cap 204 is pulled out from the top of the extrusion nozzle 203 with appropriate force. When the mixed liquid needs to be discharged, the elastic bottle body 201 is squeezed to squeeze the mixed liquid through the extrusion nozzle 203. The extrusion nozzle 203 is the extrusion port of the mixed liquid. Under normal circumstances, even if the extrusion nozzle 203 is facing downward, the mixed liquid will not flow out. The elastic bottle body 201 must be squeezed to apply pressure to the mixed liquid so that the mixed liquid can be squeezed out through the extrusion nozzle 203.

[0047] After the blood sample is added into the reagent bottle 2, the reagent bottle 2 needs to be shaken to mix the reagent and the blood sample evenly. Figure 3 , 7 As shown in , 8, a mixing assembly 6 is provided at the rear side of the vertical plate 4, and the mixing assembly 6 includes a spring 605 and a rubber tube 606 provided at the top of the mounting seat 3, the spring 605 is located inside the rubber tube 606, a film 603 is fixedly provided at the top of the spring 605, the top of the rubber tube 606 is connected to the film 603, and a small camera 604 is fixedly provided at the top of the film 603, and the picture taken by the small camera 604 can be displayed on the display screen 104.

[0048] The mixing assembly 6 further includes a fixing sleeve 601, which is made of a transparent material. Both sides of the fixing sleeve 601 are fixed with sheet-like protrusions. The inner wall of the fixing sleeve 601 is fixed with elastic pads 602. The bottom film 603 is arranged at the bottom end of the fixing sleeve 601. When the blood sample is mixed with the reagent, the elastic bottle body 201 is inserted into the fixing sleeve 601, and the inner side of the elastic pad 602 contacts the outer end of the elastic bottle body 201.

[0049] A detachable transparent support plate 607 is provided on the inner wall of the fixing sleeve 601, and the small camera 604 is arranged inside the fixing sleeve 601 and located at the bottom of the transparent support plate 607. Although the transparent support plate 607 and the negative film 603 are connected to the fixing sleeve 601, the two do not seal the bottom end of the fixing sleeve 601, and both can be disassembled and separated from the fixing sleeve 601.

[0050] After the blood sample is added into the reagent bottle 2, the bottom end of the elastic bottle body 201 is inserted into the fixed sleeve 601. Under the elastic force of the elastic pad 602, the lower half of the elastic bottle body 201 is clamped and fixed inside the fixed sleeve 601. Then, the fixed sleeve 601 is pulled by the sheet-like protrusion, thereby driving the spring 605 to bend. After the sheet-like protrusion is loosened, the fixed sleeve 601 loses its restraint, and the elastic force of the spring 605 is released, driving the fixed sleeve 601 to swing violently, thereby driving the reagent bottle 2 to shake, so that the reagent and the blood sample are mixed evenly. This operation is repeated several times. During the mixing process, The small camera 604 can capture the mixing of the reagent and blood inside the elastic bottle body 201 through the transparent support plate 607 and the transparent bottle bottom 202, and display the captured image on the display screen 104 in real time. Therefore, during the mixing process, the mixing situation can be observed in real time through the display screen 104 to determine whether the reagent and the blood sample are mixed evenly. The small camera 604 also shakes with the fixed sleeve 601 during the mixing process. Therefore, the small camera 604 and the reagent bottle 2 are always in a relatively static state. The image taken by the small camera 604 is clearer and will not be affected by shaking.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
