[0027] In order to further understand the content of the present application, the present application will be described in detail in conjunction with the drawings and embodiments. It should be understood that the embodiments are only used to explain the present application and not to limit the present application.

[0028] The following will be described in detail in conjunction with the drawings and embodiments Figures 1-5 The present embodiment will be described in further detail.

[0029] In conjunction with Figures 1-6 As shown in the drawings, the blood mixing device in the present embodiment comprises a base 100 and a roller assembly arranged on the base 100. The roller assembly is swingably mounted on the upper side of the base 100 through a swing assembly 110. The roller assembly comprises a roller housing 120. The upper side of the roller housing 120 is concave to form a groove 121. The groove 121 is parallelly arranged with rotatable rollers 122. The roller housing 120 is provided with a mounting cavity 201. The mounting cavity 201 is provided with supports 210 for mounting corresponding rollers 122. One side of the support 210 is provided with a servo motor 211 for driving the roller 122 to rotate. The mounting cavity 201 is provided with a distance adjusting assembly for adjusting the distance between adjacent supports 210.

[0030] In actual use, strip-shaped slots 1221 are arranged on the opposite side walls of the groove 121 in a direction perpendicular to the roller 122. The two ends of the roller 122 are rotatably mounted on the support 210 through a rotating shaft penetrating the corresponding strip-shaped slot 1221, as shown in Figure 2 and Figure 3 As shown in the drawings, the servo motor 211 is fixedly mounted on one side wall of the support 210 and is used to connect the corresponding rotating shaft to drive the roller 122 to rotate. Therefore, in actual use, the bottle containing the blood sample is placed between the two rollers 122. The bottle is driven to rotate by driving the roller 122 to rotate through the servo motor 211, so that the blood in the bottle is mixed.

[0031] The variable pitch component, in conjunction with the strip groove 1221, allows for the synchronous adjustment of the spacing between adjacent supports 210, thereby adjusting the spacing between adjacent rollers 122. This enables bottles of different diameters to be placed between adjacent rollers 122, thus improving the applicability of the device.

[0032] The oscillating component enables the roller housing 120 to oscillate reciprocally above the base 100, which, in conjunction with the roller 122 driving the bottle to rotate, further improves the mixing effect of the blood in the bottle.

[0033] In this embodiment, the pitch-changing assembly includes a slide plate 220 slidably disposed in the mounting cavity 201. The slide plate 220 is provided with a groove 221 corresponding to the bracket 210. The bracket 210 is provided with a sliding column 212 located in the corresponding groove 221. The mounting cavity 201 is provided with a first driving member for driving the slide plate 220 to move along the extension direction of the roller 122.

[0034] In this embodiment, a slide rail (not shown in the figure) is provided on the inner wall of the mounting cavity 201 along the axial direction of the roller 122, and the slide plate 220 is slidably mounted on the slide rail, thereby realizing the stable sliding of the slide plate 220 in the mounting cavity 201;

[0035] In this embodiment, the number of rollers 122 is set to 5, and the number of brackets 210 is adapted to the number of rollers 122. The groove 221 is designed with the middle bracket 210 as the guide. Figure 2 As shown, the central slide 221 is arranged along the axial direction of the roller 122. The slides 221 on both sides of the central slide 221 are inclined. Therefore, with the cooperation of the slide 221 and the corresponding slide column 212, when the first driving member drives the slide plate 220 to reciprocate along the axial direction of the roller 122, the side walls of the slides 221 on both sides of the central slide 221 press against the corresponding slide column 212, so that the position of the central support 210 remains unchanged. With the support 210 as the boundary, the supports 210 on both sides move away from or closer to each other to adjust the distance between adjacent supports 210. In actual use, in order to make the adjacent supports 210 move at equal intervals, the inclination angle of the corresponding slide 221 can be designed so that the movement of the slide plate 220 drives the supports 210 on both sides of the central support 210 to adjust at equal intervals.
