Description

Technical Field

[0001] The utility model relates to the technical field of smear machines, in particular to a smear base suitable for high-speed centrifugation. Background Art

[0002] The cell smear centrifuge uses high-speed spinning of the centrifuge cup to rapidly sediment the cell suspension under the action of centrifugal force. During the centrifugation process, the cell components separate according to their density, with denser cells settling at the bottom of the cup and less dense cells suspended at the top. By controlling the centrifugation time and speed, cell components of different densities can be separated. The separated cell suspension can then be applied to a glass slide to create a smear.

[0003] During centrifugation, the cell suspension is placed in a centrifuge tube and centrifuged by rotating the centrifuge tube. However, in current cell smear centrifuges, the centrifuge tube is movably plugged into the centrifuge disk or clamped on the centrifuge disk. During high-speed centrifugation, the centrifuge tube is prone to shaking or moving up and down, thereby affecting the centrifugal effect and making it difficult to adapt to high-speed centrifugation requirements.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figures 1 to 4 As shown, the smear base of the present invention includes a filter membrane cup 1 and a mounting seat 2.

[0022] The filter membrane cup 1 is used to hold a cell suspension and achieve cell stratification during centrifugation. A rotating clamp 3 is provided at its lower end for secure connection to the mounting base 2. The rotating clamp 3 comprises a filter membrane base 31 and a clamping plate 32. The filter membrane base 31 is fixed to the bottom of the filter membrane cup 1, while two clamping plates 32 are provided, symmetrically distributed on the outer wall of the filter membrane base 31.

[0023] Figure 4 As shown, the mounting seat 2 is used to install the entire smear base in the centrifuge. A clamping portion 4 is provided thereon for cooperating with the rotating clamping member 3 to achieve a stable fixation of the filter membrane cup 1. Specifically, a mounting groove 21 is provided in the mounting seat 2, and the clamping portion 4 is provided in this mounting groove 21. The clamping portion 4 includes a clamping groove 41 and a limiting plate 42 symmetrically arranged on the side wall of the mounting groove 21. The clamping groove 41 is used to receive the clamping plate 32, and a stable connection is achieved by the close contact between its inner wall and the clamping plate 32. The limiting plate 42 is provided above the clamping groove 41, and is used to abut against the upper side of the clamping plate 32 to further enhance the stability of the connection.

[0024] In actual operation, when the filter membrane cup 1 needs to be fixed to the mounting base 2, it is only necessary to rotate the clamping plate 32 into the clamping groove 41 until it is tightly abutted against the inner wall of the clamping groove 41 and the upper side of the clamping plate 32 abuts against the limit plate 42. This connection method is simple and easy to use, and can ensure that the filter membrane cup 1 will not shake or move during high-speed centrifugation.

[0025] In order to further enhance the stability and service life of the structure, Figure 2 and Figure 3 As shown, the clamping plate 32 is extended outwardly along the filter membrane base 31, and its outer wall is arc-shaped, matching the arc-shaped inner wall of the clamping groove 41. This design increases the contact area and improves the stability of the connection.

[0026] In addition, the bottom of the filter membrane base 31 is provided with a fixing groove 311 for installing the filter membrane, which facilitates the replacement of filter membranes of different specifications according to actual needs. At the same time, the top of the filter membrane cup 1 is also threaded with an end cap, which is used to seal the filter membrane cup 1 during centrifugation to prevent the cell suspension from splashing out.

[0027] To sum up, the smear base suitable for high-speed centrifugation of the utility model realizes a firm connection between the filter membrane cup and the mounting seat through a unique rotating clamping part and clamping part design, effectively solves the problem that the centrifuge tube is prone to shaking or moving during high-speed centrifugation, and improves the centrifugal effect and service life.

[0028] Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.
