Description

Technical Field

[0001] This utility model relates to the field of biotechnology equipment technology, and in particular to a fully automated chromosome harvester. Background Technology

[0002] Fully automated chromosome harvesters (also known as automated cell harvesters) can automatically harvest metaphase chromosomes from peripheral blood, bone marrow, amniotic fluid, blood-stained cells, chorionic villus cells, or other samples. They are also suitable for micronucleus and FISH applications. This system automatically completes the pre-harvest process of cell chromosomes through a pre-set program, including automatic addition of colchicine and incubation at a controlled temperature, hypotonic treatment of cells, pre-fixation, and fixation. It automatically centrifuges the cell suspension, discards the supernatant, adds hypotonic and fixative solutions, and performs shaking and pipetting operations. Examples include a harvesting and processing system for fully automated chromosome harvesting equipment disclosed in Chinese Utility Model Patent CN209117705U, and a high-efficiency multi-drug injection device and its chromosome harvesting and processing system disclosed in Chinese Utility Model Patent CN 211284347U, etc. However, current equipment of this type usually has the following problems: In the harvesting chamber of the chromosome harvester, due to the oscillation and rotation of the harvester's process for handling tissue fluid, the liquid will splash out / evaporate and gradually deposit on the inner wall of the chamber. This will cause bacteria and other sources of contamination to grow in the chamber, thus affecting the processing effect of the equipment. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a chromosome harvesting and processing device with sterilization function that features a simple structure, a more rational design, and the ability to solve bacterial contamination.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a chromosome harvesting and processing device with sterilization function, comprising a main unit, the main unit having a body and a centrifuge mechanism, the centrifuge mechanism being located below the harvesting chamber of the main unit; an ultraviolet light source is provided in the harvesting chamber, the ultraviolet light source being connected to the main unit and facing the harvesting chamber and the centrifuge mechanism; a motor is installed on the body, the motor being connected to the main unit and connected to a scattering lens, a focusing lens and a light shield, the scattering lens being driven by the motor to block in front of the ultraviolet light source to form a structure that scatters light toward the harvesting chamber, the focusing lens being driven to block in front of the ultraviolet light source to form a structure that focuses light toward the centrifuge mechanism, and the light shield being driven to block the ultraviolet light source to form a structure that blocks the light from escaping.

[0005] Furthermore, the ultraviolet light source is installed on the bottom surface of the top plate of the machine body, with the ultraviolet light source facing downwards and aimed at the centrifuge mechanism.

[0006] Furthermore, the motor is mounted on the top plate, and the motor's output shaft passes through the top plate and connects to the scattering lens, the focusing lens, and the light-shielding plate, respectively.

[0007] Furthermore, the scattering lens, the focusing lens, and the light-shielding plate are each connected to a connecting rod, and each connecting rod is connected to the output shaft of the motor.

[0008] Furthermore, a connector is provided at the bottom of the motor's output shaft, and the connecting rods of the scattering lens, focusing lens, and light-shielding plate are respectively connected and fixed to the side of the connector.

[0009] Preferably, each connecting rod and connector is an integral structure made of plastic material.

[0010] Furthermore, each connecting rod extends horizontally from the side of the connector, so that the positions of the scattering lens, focusing lens, and light shield are lower than the position of the ultraviolet light source.

[0011] As an alternative, a safety switch can be installed next to the front compartment door on the front of the machine body. The safety switch is connected to the main unit to form a linkage structure with the front compartment door, so that the power supply of the ultraviolet light source is forcibly disconnected when the front compartment door is opened, ensuring the safety of the operator when the front compartment door is open.

[0012] This invention utilizes an ultraviolet light source within the harvesting chamber to sterilize the interior and centrifugation mechanism with ultraviolet light. This effectively inhibits bacteria and other contaminants within the chamber and centrifugation mechanism, reducing contamination and damage to samples during prolonged processing and ensuring optimal treatment results. The entire sterilization structure is simple and effective. Different functions can be achieved by switching between a light-shielding plate, a scattering lens, and a focusing lens controlled by a motor. It is simple, practical, and low-cost.

[0017] In this embodiment, refer to Figures 1-3The chromosome harvesting and processing equipment with sterilization function includes a main unit, which has a body 1 and a centrifuge mechanism 2 located below the harvesting chamber of the main unit. An ultraviolet (UV) light source 5 is installed in the harvesting chamber, connected to the main unit and facing the harvesting chamber and centrifuge mechanism. A motor 3 is installed on the body 1, controlled by the main unit. The motor 3 is connected to a scattering lens 6, a focusing lens 7, and a light-shielding plate 8. The scattering lens 6 is driven by the motor 3 to block the UV light source 5, forming a structure that scatters light towards the harvesting chamber, thus purifying and sterilizing the entire cavity of the harvesting chamber. The focusing lens 7 is driven to block the UV light source 5, forming a structure that focuses the light towards the centrifuge mechanism 2, thus focusing the UV light onto the centrifuge mechanism 2 for sterilization. The light-shielding plate 8 is driven to block the UV light source 5, forming a structure that blocks the light from escaping, thus covering the UV light source 5 during sample processing and preventing accidental opening of the UV light source 5 by the sample or operator, which could cause harm.

[0018] The ultraviolet light source 5 is installed on the bottom surface of the top plate 11 of the machine body 1, with the ultraviolet light source 5 facing downwards and aligned with the centrifugal mechanism 2. The motor 3 is installed on the top plate 11, and the output shaft of the motor 3 passes through the top plate 11 and is connected to the scattering lens 6, the focusing lens 7 and the light shield 8 respectively.

[0019] The scattering lens 6, the focusing lens 7, and the light-shielding plate 8 are each connected to a connecting rod 9, and each connecting rod 9 is connected to the output shaft of the motor 3.

[0020] A connector 4 is provided at the bottom of the output shaft of motor 3. The connecting rods 9 of the scattering lens 6, the focusing lens 7, and the light shield 8 are respectively connected and fixed to the side of the connector 4. When motor 3 is working, connector 4 will rotate, thereby driving each connecting rod 9, as well as the scattering lens 6, the focusing lens 7, and the light shield 8 to rotate simultaneously, so as to rotate the scattering lens 6, the focusing lens 7, or the light shield 8 to the desired position.

[0021] Each connecting rod 9 and the connector 4 are integrated into one structure and are made of plastic material.

[0022] Each connecting rod 9 extends horizontally from the side of the connector 4, so that the positions of the scattering lens 6, the focusing lens 7, and the light shield 8 are lower than the position of the ultraviolet light source 5, so as to block the ultraviolet light source 5 from below.

[0023] A safety switch 10 can also be installed next to the front compartment door on the front of the machine body 1. The safety switch 10 is connected to the main unit to form a linkage structure with the front compartment door, so that the power supply of the ultraviolet light source is forcibly disconnected when the front compartment door is opened, ensuring the safety of the operator when the front compartment door is open.

[0024] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
