Description

Technical Field

[0001] This application relates to the field of experimental tool technology, specifically a biological sample transfer workbench. Background Technology

[0002] In biomedical laboratories, the pharmaceutical industry, and clinical testing, it is frequently necessary to transfer biological samples (such as cell cultures, microorganisms, tissue samples, reagents, etc.) between different containers or equipment. These operations usually need to be performed in a sterile environment to prevent environmental contamination of the samples or leakage of pathogens from the samples that could endanger the health of the operators.

[0003] Existing sample transfer equipment is usually a box with a sterilization function. When transferring samples, the samples are placed in the box for transfer. This transfer method is usually suitable for long-distance transfers, but there is a risk of bumps and secondary contamination. It is not conducive to the rapid transfer of uncontaminated samples on the work surface, and the efficiency is low.

[0004] Therefore, this application provides a biological sample transfer stage to solve the above problems. Utility Model Content

[0005] This application provides a biological sample transfer workbench, which aims to solve the problems of low efficiency in existing sample transfer equipment mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a biological sample transfer workbench, comprising a work surface, a conveyor belt disposed on the work surface, a controller for controlling the operation of the conveyor belt, and a protective cover disposed on the work surface for covering the conveyor belt to prevent contamination of the biological sample.

[0007] The protective cover includes a long, narrow frame with a protective cavity inside. The frame is mounted on a conveyor belt through the protective cavity. The frame has several operating ports arranged in a linear array, each with a hinged cover. In operation, the cover of an adjacent workstation is opened, the sample is placed onto the conveyor belt through the opened operating port, the cover is closed, and the conveyor belt is started via a controller to transport the sample. When the sample reaches the next required workstation, the conveyor belt is stopped via the controller, the cover of the next workstation is opened, and the sample is removed from the operating port. The entire process does not require the sample to leave the workstation, the transport path is continuous and stable, and the protective cover effectively prevents external environmental contamination, resulting in high efficiency.

[0008] Preferably, for ease of observation, the cover plate is made of transparent material, and a handle is fixedly installed on the cover plate to facilitate observation of the movement of the sample.

[0009] Preferably, for ease of maintenance, a positioning base adapted to support the frame is fixedly installed on the table surface by bolts, and a first sealing gasket is embedded between the positioning base and the table surface to facilitate disassembly and maintenance of the frame.

[0010] Preferably, for ease of installation, a fixed frame adapted to the frame is fixedly installed on the positioning base, the frame is sleeved on the fixed frame, a second sealing gasket is sandwiched between the fixed frame and the frame, and a knob that passes through the fixed frame is screwed onto the outer wall of the frame to ensure sealing effect and facilitate disassembly and assembly.

[0011] Preferably, in order to ensure the cover is sealed, a support ring adapted to the cover is fixedly installed on the inner wall of the operating port, and a third sealing gasket is fixedly installed on the support ring to ensure the environment inside the frame is sealed.

[0012] Preferably, for disinfection purposes, several evenly distributed ultraviolet lamp strips are fixedly installed on the side of the operating port within the frame. The ultraviolet lamp strips are electrically connected to the controller, further improving the safety of the internal environment of the equipment.

[0013] This transfer workbench opens a cover of an adjacent workstation, places the sample into the conveyor belt within the frame through the opened operating port, then closes the cover, and starts the conveyor belt via the controller to transport the sample. When it reaches the next required operating station, the controller stops the conveyor belt, then opens the cover of the next adjacent workstation, and removes the sample from the operating port. The entire process does not require the sample to leave the workstation, the transfer path is continuous and stable, and the protective cover effectively prevents external environmental pollution, resulting in high efficiency.

[0014] This transfer workbench uses a controller to activate ultraviolet light strips to disinfect the transport space on the conveyor belt within the frame in real time, ensuring that samples are not secondary contaminated during the transfer process and further improving the safety of the internal environment of the equipment.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a biological sample transfer workbench, such as Figure 1-5 As shown, the transfer workbench includes a work surface 1, a conveyor belt 2 mounted on the work surface 1, a controller 3 for controlling the operation of the conveyor belt 2, and a protective cover 4 mounted on the work surface 1 to cover the conveyor belt 2 and prevent contamination of biological samples.

[0025] The protective cover 4 includes a long frame 41 with a protective cavity 42 inside. The frame 41 is covered on the conveyor belt 2 through the protective cavity 42. The frame 41 has a number of operation ports 43 arranged in a linear array, and the operation ports 43 are hinged with cover plates 44.

[0026] In use, open the cover 44 of an adjacent workstation, place the sample into the conveyor belt 2 inside the frame 41 through the opened operation port 43, then close the cover 44, start the conveyor belt 2 through the controller 3 to transport the sample, and when it reaches the next required operation station, stop the conveyor belt 2 through the controller 3, then open the cover 44 of the adjacent next workstation, and take out the sample from the operation port 43. The whole process does not require the sample to leave the workstation, the conveying path is continuous and stable, and the protection of the protective cover 4 can effectively avoid external environmental pollution, resulting in high efficiency.

[0027] Specifically, the cover plate 44 is made of transparent sheet material, and a handle 45 is fixedly installed on the cover plate 44.

[0028] In use, a cover plate 44 is made of transparent sheet material such as acrylic and tempered glass to facilitate observation of the movement of the sample. The cover plate 44 can be pulled by the handle 45 for easy operation.

[0029] More specifically, a positioning base 46 adapted to support the frame 41 is fixedly installed on the tabletop 1 by bolts, and a first sealing gasket 47 is embedded between the positioning base 46 and the tabletop 1.

[0030] In use, the frame 41 and the positioning base 46 are installed separately. The positioning base 46 is fixed to the table 1 with bolts, and the frame 41 is fitted onto the positioning base 46, which facilitates the disassembly and maintenance of the frame 41.

[0031] Furthermore, a fixed frame 48 adapted to the frame 41 is fixedly installed on the positioning base 46. The frame 41 is sleeved on the fixed frame 48. A second sealing gasket 49 is sandwiched between the fixed frame 48 and the frame 41. A knob 410 that passes through the fixed frame 48 is screwed onto the outer wall of the frame 41.

[0032] In use, the second sealing gasket 49 is fitted onto the fixing frame 48, and then the frame 41 is fitted onto the positioning base 46 to clamp the second sealing gasket 49. Then, the frame 41 and the positioning base 46 are fixed by the knob 410 to ensure the sealing effect and facilitate disassembly and assembly.

[0033] Furthermore, a support ring 411 adapted to the cover plate 44 is fixedly installed on the inner wall of the operating port 43, and a third sealing gasket 412 is fixedly installed on the support ring 411.

[0034] When in use, the cover plate 44 is attached to the support ring 411 when closed.

[0035] Example 2

[0036] Unlike Embodiment 1, when the conveyor belt 2 is in operation, bacteria may enter the space inside the frame 41 when the cover plate 44 is repeatedly opened and closed. Therefore, several evenly distributed ultraviolet lamp strips 5 are fixedly installed inside the frame 41 on the side of the operation port 43. The ultraviolet lamp strips 5 are electrically connected to the controller 3.

[0037] During use, the ultraviolet light strip 5 is turned on by the controller 3 to disinfect the transport space on the conveyor belt 2 inside the frame 41 in real time, ensuring that the sample will not be contaminated during the transfer process and further improving the safety of the environment inside the equipment.
