[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0068] Existing blood cell detection and immunoassay devices are mostly automatically detected. During the detection of the analyte, a lead screw motor is mostly used to drive a camera to take pictures for clinical observation. However, the lead screw motor drive will have jitter, and the lead screw motor has poor repeat positioning accuracy, and the positioning error can only be controlled within 0.01 mm, resulting in phenomena that affect the photographing effect and detection performance. To at least solve one of the above technical problems, the embodiments of the present application provide a medical detection device, which can solve the technical problems of jitter and poor positioning accuracy during the detection process, which affect the photographing effect and detection performance.

[0069] Specifically, as Figure 1 shown, the embodiments of the present application provide a medical detection device, which includes a Y-axis drive platform 1, an X-axis drive platform 2, a three-in-one reagent card (not shown in the figure), a pipetting device 3, and a camera device 4. The Y-axis drive platform 1 is provided with a stage, and the Y-axis drive platform 1 can drive the stage to move along the Y-axis. The X-axis drive platform 2 is arranged on the stage to move along the Y-axis under the transportation of the stage and the drive of the Y-axis drive platform 1. The three-in-one reagent card is used for the detection of blood cells, hemoglobin, and inflammatory indicators. The three-in-one reagent card is arranged on the X-axis drive platform 2 to move along the X-axis under the drive of the X-axis drive platform. In summary, under the drive of the two drive platforms, the three-in-one reagent card completes two-way positioning, making the detection automated and more accurate.

[0070] It should be noted that the three-in-one reagent card provided in the embodiments of the present application can simultaneously detect three types of medical indicators, namely blood cell detection, hemoglobin detection, and inflammatory indicator detection. The above detections can be completed simultaneously through the three-in-one reagent card, minimizing medical consumables as much as possible. In addition, during the blood cell detection process, the above three-in-one reagent card combined with this device can complete the five-classification blood cell detection, that is, the detection of neutrophils, lymphocytes, eosinophils, basophils, and monocytes in the white blood cells of blood cells, which is more comprehensive and specific than the three-classification detection and has more clinical value in medicine.

[0071] More specifically, as Figure 1 shown in combination with Figures 2 to 6 shown, the above pipetting device 3 is arranged above the Y-axis driving platform 1 and the X-axis driving platform 2 and is used for sampling the object to be measured and moving the sample. The camera device 4 is arranged on one side of the pipetting device 3 and is used for photographing the object to be measured. Specifically, the camera device 4 includes a Z-axis driving mechanism 54, a microscopic camera assembly 52, and a gearbox reducer. The microscopic camera assembly 52 is arranged at the output end of the Z-axis driving mechanism 54 to move along the Z-axis under the drive of the Z-axis driving mechanism 54. The gearbox reducer is adapted to the Z-axis driving mechanism 54 to perform deceleration adjustment on the Z-axis driving mechanism 54.

[0072] The detection process of the medical detection device provided in the embodiments of the present application is as follows: When detecting the object to be measured, the object to be measured is dropped onto the three-in-one reagent card, and the three-in-one reagent card is placed on the X-axis driving platform 2. The Y-axis driving platform 1 drives the carrier table to drive the X-axis driving platform 2 to move along the Y-axis, and the X-axis driving platform 2 drives the three-in-one reagent card to move along the X-axis. In the case of positioning completion, the pipetting device 3 samples the object to be measured and moves the sample to a preset position. The microscopic camera assembly 52 is driven by the Z-axis driving mechanism 54 and adjusts under the gearbox reducer to photograph the object to be measured throughout the process.

[0073] From the above content, it can be seen that in the embodiments of the present application, the gearbox reducer is set to adjust the motor. Compared with the detection device that only sets a lead screw motor, the medical detection device provided in the present application has higher stability during the detection process, and there will be no jitter phenomenon during the detection process, ensuring the stability of the CCD camera 521 during the detection. In addition, through the positioning adjustment of the gearbox reducer, the positioning accuracy of the object to be measured is improved, and the detection accuracy is increased. After measurement, the positioning accuracy of the detection device equipped with the gearbox reducer can reach 0.001 mm, while the positioning accuracy of the original detection device driven only by the lead screw motor can only reach 0.01 mm.

[0074] In an alternative example, as Figures 2 to 6As shown, the gearbox reducer includes a gearbox main body 59, a gearbox cover plate 58, a gearbox fixing member 60, and upper and lower gearbox fixing plates 61. The gearbox cover plate 58 is covered on the gearbox main body 59. The gearbox fixing member 60 is connected to the gearbox main body 59 and is used to fix the gearbox main body 59 on the gearbox cover plate 58. The upper and lower gearbox fixing plates 61 are arranged on the periphery of the gearbox main body 59 and are configured as assembly plates of the gearbox main body 59. By arranging the structure of the gearbox reducer, the volume ratio of the structure is minimized as much as possible, the volume structure of the medical detection device is simplified, and the space occupancy rate is reduced.

[0075] In an alternative example, as Figure 5 shown, the microscope camera assembly 52 provided in the embodiment of the present application includes: a CCD camera 521, a lens barrel 523, and a conversion head 522. An objective lens 524 is provided on the lens barrel 523. The conversion head 522 is used to connect the CCD camera 521 and the lens barrel 523. Through the microscope camera assembly 52, the object to be measured can be directly detected and processed.

[0076] Furthermore, as Figures 2 to 6 shown, the camera device 4 further includes a Z-axis movement top plate 50 for installing the Z-axis drive mechanism 54, and a camera fixing plate 51 for installing the microscope camera assembly 52. The Z-axis movement top plate 50 and the camera fixing plate 51 are configured as assembly plates of the camera device 4.

[0077] Still further, as Figure 5 shown, the camera device 4 further includes a helical pin 62 and a helical rack 63 for locking the microscope camera assembly 52 on the Z-axis drive mechanism 54. The helical pin 62 and the helical rack 63 are arranged at the side end of the microscope camera assembly 52 and are connected to the output end of the Z-axis drive mechanism 54.

[0078] Even further, the camera device 4 further includes a camera optocoupler fixing plate 55 and a camera optocoupler shutter 56. The camera optocoupler fixing plate 55 and the camera optocoupler shutter 56 are arranged at the shooting end of the microscope camera assembly 52 to assist the microscope camera assembly 52 in shooting, so that the shooting information can be transmitted to the detection terminal of the detection personnel in the form of optical signals.

[0079] It should be noted that the Z-axis drive mechanism 54 provided in the embodiment of the present application can be a drive motor. In the structure provided in the embodiment of the present application, necessary guide rails, etc. need to be equipped for navigation, and the existing guide rails, etc. are not described in detail in the embodiment of the present application. In addition, during the process of the microscope camera assembly 52 shooting the detection, a colloidal gold camera 64 and a colloidal gold supplementary light 65 can be additionally equipped for auxiliary shooting (as Figure 6 ), to ensure the shooting clarity.

[0080] In another alternative example of the present application, as Figures 7 to 8 shown, the pipetting device 3 provided by the embodiment of the present application includes a Z-axis lead screw motor 36, a sampling rod 43, and a sampling tip 45. The sampling rod 43 is arranged at the output end of the Z-axis lead screw motor 36 to suck the sampling tip 45 and move along the Z-axis under the drive of the Z-axis lead screw motor 36.

[0081] Furthermore, the pipetting device 3 further includes an injection pump 37. The injection pump 37 is arranged at the side end of the Z-axis lead screw motor 36 and is used to pump out the sample liquid.

[0082] It should be noted that, as Figures 7 to 8 shown, the pipetting device 3 further includes a Z-axis pipetting top plate 38, a Z-axis pipetting vertical plate 39, a Z-axis pipetting bottom plate 40, a Z-axis pipetting linear guide rail 41, a Z-axis pipetting slide rail fixing block 42, a pipe joint 44, a Z-axis pipetting opto-coupler baffle 46, a Z-axis pipetting opto-coupler fixing member 47, a Z-axis pipetting opto-coupler sensor 48, a deep groove ball bearing 49 and other necessary structures to assist in pipetting, and cooperate with the camera device 4 to assist in shooting and information transmission. For example, the Z-axis pipetting top plate 38, the Z-axis pipetting vertical plate 39, the Z-axis pipetting bottom plate 40, the Z-axis pipetting linear guide rail 41, the Z-axis pipetting slide rail fixing block 42, the pipe joint 44, etc. jointly constitute the structure of the pipetting device 3 to assist in pipetting; the Z-axis pipetting opto-coupler baffle 46, the Z-axis pipetting opto-coupler fixing member 47, the Z-axis pipetting opto-coupler sensor 48 cooperate with the camera device 4 to assist in shooting and information transmission.

[0083] In another alternative example of the present application, as Figure 9 shown, the medical detection device provided by the embodiment of the present application further includes a communication device 5. The communication device 5 is electrically connected to the camera device 4 to transmit the shooting result.

[0084] Furthermore, the communication device 5 includes: a communication circuit board 67, an RJ45 to USB adapter 66, an external interface 69, and a switch 68. The communication circuit board 67 is electrically connected to the camera device 4. The RJ45 to USB adapter 66 is integrated on the communication circuit board 67 and is used to connect the camera device 4; the external interface 69 is integrated on the communication circuit board 67 and is used to access external devices. The switch 68 is integrated on the communication circuit board 67 and is used to control the opening and closing of the communication circuit board 67.

[0085] It should be noted that the above-mentioned communication device 5 is an external structure, which needs to be communicatively connected to the medical detection device to ensure information transmission and facilitate the detection personnel to receive detection information at any time.

[0086] According to the medical detection device provided by the embodiments of the present application, by setting a gearbox reducer to adjust the motor, compared with the detection device that only sets a lead screw motor, the medical detection device provided by the present application has higher stability during the detection process, and there will be no jitter phenomenon during the detection process, ensuring the stability of the camera shooting during the detection; in addition, through the positioning adjustment of the gearbox reducer, the positioning accuracy of the object to be measured is improved, and the accuracy of the detection is increased.
