Description
Technical Field
[0001] This utility model relates to the field of medical testing equipment technology, and in particular to a blood analyzer sampling device. Background Technology
[0002] In medical testing equipment, samples need to be aspirated, transported, and tested by a sampling mechanism to obtain test results. For sample aspiration after testing, the most common process involves placing the sample in a designated location for aspiration and transport by the sampling mechanism. This transfer action requires a specialized sampling mechanism. Traditional sampling mechanisms simply aspirate by moving up and down, with a loading platform below for loading. This method is labor-intensive and has significant limitations. Summary of the Invention

[0015] Furthermore, both the horizontal movement sensing mechanism and the vertical movement sensing mechanism are photoelectric sensors, and a horizontal baffle and a vertical baffle for blocking the photoelectric sensors are connected between the two.
[0016] The beneficial effects of this invention are as follows: During use, the horizontal movement drive mechanism of the horizontal motion component drives the fixed base to move horizontally via the horizontal movement transmission mechanism, which in turn drives the second support of the vertical motion component to move.

The second bracket 210 is connected to a horizontal guide auxiliary mechanism 150, and the vertical motion assembly 200 is connected to a fixed base 141. The horizontal movement drive mechanism 120 drives the horizontal movement transmission mechanism 130 to move the fixed base 141 horizontally.
[0037] The sampling mechanism 300 includes a sampling needle 310 and a swab 320 connected to the end of the sampling needle 310. The sampling needle 310 is connected to the vertical slider 250 through a connector. The sampling needle 310 is arranged parallel to the vertical linear guide shaft 240. The vertical movement drive mechanism 220 drives the vertical slider 250 to move along the vertical linear guide shaft 240 through the vertical movement transmission mechanism 230.
[0038] In use, the horizontal movement drive mechanism 120 of the horizontal motion component 100 drives the fixed base 141 to move horizontally via the horizontal movement transmission mechanism 130, which in turn drives the second support 210 of the vertical motion component 200 to move. The horizontal guide auxiliary mechanism 150 ensures the stability of the second support 210's horizontal movement. The vertical movement drive mechanism 220 of the vertical motion component 200 drives the vertical movement transmission mechanism 230 to move the vertical slider 250 along the vertical linear guide axis 240, thereby driving the sampling mechanism to move vertically. Both horizontal and vertical movements are equipped with sensing mechanisms, enabling convenient and precise position control. The horizontal motion component 100 can drive multiple vertical motion components 200 to move horizontally simultaneously, which can improve work efficiency while reducing costs.
[0039] Please refer to Figure 2 and Figure 5The vertical motion component 200 includes two vertical linear guide shafts 240, which are horizontally spaced apart. The vertical slider 250 is nested and slides with both vertical linear guide shafts 240. The two vertical linear guide shafts 240 enhance vertical stability and ensure vertical movement.

The horizontal slide 153 is located below the horizontal guide rail 151, and the roller 154 slides in conjunction with the horizontal slide 153. The roller 154 includes a rotating wheel and a central shaft sleeved within the rotating wheel. The second support 210 has an extension frame, and both ends of the central shaft are connected to the extension frame. This provides horizontal movement limits at both the upper and lower ends of the second support 210, improving the stability of horizontal movement and preventing deviation. It is understood that the central shaft can be either a fixed shaft or a rotating shaft. When a fixed shaft is used, it rotates in conjunction with the rotating wheel; when a rotating shaft is used, bearings are correspondingly installed on the extension frame to facilitate the rotation of the rotating shaft.
[0043] Please refer to Figure 2 and Figure 3 The horizontal movement drive mechanism 120 includes a first motor, and the horizontal movement transmission mechanism 130 includes a first driving pulley 131, a first driven pulley 132, and a first synchronous belt 133. The first driving pulley 131 and the first driven pulley 132 are horizontally spaced apart.

[0049] Specifically, the vertical motion component 200 includes two vertical linear guide shafts 240 and two vertical sliders 250. The two vertical linear guide shafts 240 on the same vertical motion component 200 are horizontally spaced apart, and the two vertical sliders 250 are vertically spaced apart, with one vertical slider 250 simultaneously nested and sliding with both vertical linear guide shafts 240. The two vertical linear guide shafts 240 enhance vertical stability and ensure vertical movement; the two vertical sliders 250 improve the overall stability of the second support 210. Furthermore, it eliminates the need for a vertical movement auxiliary mechanism, reducing costs, simplifying equipment complexity, and facilitating maintenance. Specifically, on the same vertical motion component 200, both vertical sliders 250 are connected to the sampling needle 310, ensuring the stability and connection strength of the sampling needle 310. Specifically, the sampling needle 310 and the vertical slider 250 are detachably connected.
