The repeated use of the phrase "in one embodiment" does not necessarily refer to the same embodiment, although it can.

[0022] In the present embodiment: as shown in Figure 1 The test tube assembly, the limiting structure and the rotating structure are included. The mechanical operation sequence is forced to be controlled through the cooperation of multiple modules, so as to reduce the risk of human error.

[0023] The test tube assembly includes a test tube 2 and a test tube cover 1. The test tube 2 is in sealed cooperation with the test tube cover 1 to avoid reagent pollution or volatilization. The test tube cover 1 is embedded with a silica gel sealing ring. The test tube 2 is made of transparent medical-grade polypropylene (wall thickness 1.2 mm)

[0024] The limiting structure includes a limiting plate 12, a limiting frame 5 and a torsion spring 11. The limiting plate 12 is hinged to the test tube cover 1 through the torsion spring 11. The limiting frame 5 is internally provided with a guide channel 51 for restricting the movement path of the limiting plate 12. The limiting plate 12 is forced to move along the preset path.

[0025] The rotating structure includes a rotating disc 4 and a base 3. The upper end of the rotating disc 4 is provided with an annular sliding groove 42. The base 3 is provided with an annular sliding rail 31 corresponding to the annular sliding groove 42. The rotating disc 4 is provided with a plurality of test tube 2 mounting grooves 41, which realizes precise angle stepping rotation and ensures that the test tubes 2 enter the operation position one by one, supports multiple reagent parallel management and adapts to standard detection process.

[0026] The test tube cover 1 is provided with an L-shaped tab 13. The tab 13 is fixed to the outer surface of the test tube cover 1. The tab 13 is provided with anti-slip lines to provide a clear force point and reduce the difficulty of opening the cover.

[0027] The limiting plate 12 and the upper end surface of the test tube cover 1 form an included angle of 45°-75°, which balances the mechanical strength and operation force and avoids accidental deformation of the limiting plate 12. The included angle is preferably 60°.

[0028] The limiting frame 5 is provided with a 60°-90° sector gap. The limiting frame 5 and the base 3 are fixedly connected to match the stepping angle of the rotating disc 4 and ensure that only one test tube 2 can be operated at a time.

[0029] The bottom surface of the base 3 is provided with an adsorption structure 32, which includes at least three suction disc units distributed in a ring shape, so as to enhance the stability of the device and avoid displacement during operation.

[0030] The guide channel 51 of the limiting frame 5 includes an initial blocking section 52 for limiting the movement of the test tube 2, so as to physically prevent the test tube 2 from being triggered by mistake during operation and provide tactile feedback.

[0031] More specifically, the utility model relates to a kit for cell detection, which comprises a test tube assembly, a limiting structure and a rotating structure. The test tube assembly comprises a test tube 2 and a test tube cover 1 provided with an L-shaped tab 13, and the surface of the tab 13 is processed with diamond-shaped anti-skid lines with a depth of 0.3-0.5 mm to assist manual opening and closing.

[0032] The limiting structure is composed of a limiting plate 12 hinged to the test tube cover 1 by a torsion spring 11 and a limiting frame 5 provided with a guide channel 51, and the limiting plate 12 is initially at an angle of 60° with the test tube cover 1. The limiting frame 5 is fixed to the base 3 by bolts, and the internal guide channel 51 is divided into an initial blocking section 52 and a passing section 53. The passing section 53 is a movement channel after the limiting plate is unlocked for sliding, and the width of the channel is larger than the thickness of the limiting plate 12 to realize sliding limiting. The rotating structure comprises a turntable 4 and a base 3, and the turntable 4 is provided with six test tube 2 mounting grooves 41. Rubber sealing rings are embedded in the grooves to fix the test tubes 2. The lower end of the turntable 4 is processed with a T-shaped annular sliding groove 42, and the base 3 is correspondingly provided with a T-shaped annular sliding rail 31. The gap between the two is matched to realize 60° step rotation. The bottom of the base 3 is provided with four silica gel suction disc units distributed in a 90° ring shape to ensure stable operation.

[0033] In embodiment 2, for a four-step detection process, the mounting grooves 41 of the turntable 4 are changed to four, the limiting angle of the sliding rail 31 is adjusted to 90°, and the fan-shaped gap of the limiting frame 5 is synchronously expanded to 90°.

[0034] In the working process: in the initial state, the first test tube 2 is in the gap of the limiting frame 5, and the limiting plates 12 of the remaining test tubes 2 are clamped into the passing section 53 of the limiting frame 5, and the turntable 4 cannot be rotated due to mechanical interlocking.

[0035] After the liquid taking operation on the test tube 2 is completed by the tab 13, the limiting plate 12 of the first test tube 2 is pressed to pass through the initial blocking section 52 and enter the passing section 53. The limiting plate 12 of the next test tube 2 enters the blocking section of the limiting frame 5.

[0036] If the user forcibly rotates without closing the test tube cover 1, the limiting plate 12 that has not been reset will collide with the side wall of the limiting frame 5 to generate resistance and prevent mistaken operation.

[0037] The design realizes high-precision anti-misoperation with single-step operation time less than or equal to 3 seconds and small rotation angle deviation through the hard interlocking of the limiting plate 12 and the frame, the automatic reset of the torsion spring 11 and the step control of the T-shaped slide rail 31, and is especially suitable for high-throughput laboratory scenes.
