Filtering sorter

Abstract

Through the arrangement of a driving part, a middle channel pipeline can be driven to rotate in the process that a culture solution is filled and filtered and sorted by using a filter membrane, and a spiral guide plate on the inner wall of the middle channel pipeline rotates along with the middle channel pipeline; when the culture solution flows downwards through the middle channel pipe, the flowing direction of the culture solution penetrating through the filter membrane is not traditional vertical downward, so that the risk that the filter membrane is blocked can be effectively reduced.

Description

Technical Field

[0001] This utility model relates to the field of cell sorting technology, specifically a filter sorting instrument. Background Technology

[0002] Stem cells are a type of pluripotent cell with self-replication ability. Under certain conditions, they can differentiate into various functional cells and have broad application prospects in clinical treatment. Stem cell culture usually includes steps such as filtration, sorting, and enrichment. In filtration and sorting, the culture medium flows to a filter membrane with filtration effect for filtration and sorting. However, if the direction of the culture medium flowing down the filter membrane remains unchanged, long-term use can easily lead to filter membrane blockage. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a filter sorting instrument. The technical solution adopted includes a lower plate, a fixed filter cartridge, a filter membrane, a mounting part, an outer cylinder, an outer box, a motor, a central channel tube, a spiral guide plate, a removable plug, a U-shaped ring, a circular ring, and a drive part. The fixed filter cartridge is fixed at the through hole in the center of the lower plate, and the filter membrane is installed inside the fixed filter cartridge. The mounting part is set in the area outside the fixed filter cartridge on the lower plate. The outer cylinder is installed through the mounting part. The outer box is integrally formed on the upper side of the outer cylinder. The motor is installed on the outer box. Two U-shaped rings are integrally formed on the inner wall of the outer cylinder. Two rings are integrally formed on the outer wall of the central channel tube, and the rings fit into a U-shaped ring. The top of the central channel tube is sealed with a removable plug. After opening the removable plug, the culture medium is added from the opening at the top of the central channel tube. A spiral guide plate is integrally formed on the inner wall of the central channel tube. The upper ring is driven to rotate by a drive unit set in the outer box. As the upper ring rotates, the central channel tube also rotates synchronously, and the spiral guide plate on its inner wall rotates accordingly. When the culture medium flows down through the central channel tube, its flow direction when passing through the filter membrane is not the traditional vertical downward direction, which can effectively reduce the risk of filter membrane clogging.

[0004] As a preferred technical solution of this utility model, the mounting part includes an upper mounting frame, an internal thread and an external thread cylinder. The inner wall of the upper mounting frame is provided with an internal thread, and the external thread cylinder is installed in conjunction with the internal thread. The inner wall of the external thread cylinder is in contact with the outer wall of the fixed filter cylinder.

[0005] As a preferred embodiment of this invention, the motor is powered by a battery and controlled by a remote control device.

[0006] As a preferred technical solution of this utility model, the inner ring is integrally formed at the bottom of the inner wall of the outer cylinder. After the outer threaded cylinder is assembled and connected with the upper mounting frame, the bottom surface of the inner ring contacts the top surface of the fixed filter cylinder.

[0007] As a preferred technical solution of this utility model, the drive unit includes an external tooth surface and a gear. The outer box body is connected to the groove of the upper cross-section U-shaped ring. The output shaft of the motor extends into the outer box body and the gear is fixedly installed at its output end. The outer side of the upper ring is the external tooth surface. The external tooth surface and the gear mesh with each other. After the motor starts, it can drive the gear to rotate. Under the meshing of the gear and the external tooth surface, it can drive the upper ring to rotate, thereby causing the middle channel tube to rotate.

[0008] The beneficial effects of this utility model are as follows: By setting the drive unit, the central channel pipe can be driven to rotate during the process of filling the culture medium and filtering and sorting it using the filter membrane. The spiral guide plate on its inner wall rotates accordingly. When the culture medium flows down through the central channel pipe, its flow direction when passing through the filter membrane is not the traditional vertical downward direction, which can effectively reduce the risk of the filter membrane being blocked.
