[0002] In the field of cell culture, serum, as a key natural culture medium component, is rich in various nutritional ingredients required for cell growth and is an indispensable substance for animal cell in vitro culture. Serum is usually purchased in the form of a large-capacity bottle with a capacity of 1L to meet the needs of large-scale cell culture experiments. However, the amount of serum required each time during the actual preparation of complete culture medium is only about 40ml. In order to avoid the risk of contamination that may be caused by repeatedly taking serum from the storage bottle, as well as the potential damage to the effective ingredients in the serum caused by repeated freezing and thawing, researchers usually need to quantitatively sub-pack the large bottle of serum, and the sub-packaging specifications are usually 40ml tubes, i.e. the serum is sub-packaged into 40ml centrifugal tubes for subsequent use.

[0003] The sub-packaging process is usually carried out under strict sterile conditions, i.e. in a clean bench, to ensure a sterile state. However, after sub-packaging is completed, in order to ensure the sterility of the serum during subsequent storage and use, the centrifugal tube opening also needs to be sealed with a membrane to prevent external sources of contamination from entering the centrifugal tube through the small gap between the tube opening and the tube cover, thereby protecting the serum from contamination.

[0028] The fixing member 2 is detachably connected to the upper end of the base 11, used for fixing the centrifugal tube 3, ensuring that the centrifugal tube 3 does not move when winding the sealing film;

[0029] The rotating member 4 is fixedly installed on the top plate 12, the output shaft of the rotating member 4 is connected to the support rod 5, and the support rod 5 is provided with a through channel, which is directed to the opening edge of the centrifugal tube 3;

[0030] The placing cylinder 6 is arranged on the side of the support rod 5 away from the centrifugal tube 3, and the placing cylinder 6 is used for storing the sealing film and is provided with an opening communicating with the channel, so that the end of the sealing film can pass through the channel and be wound on the centrifugal tube 3;

[0031] The control switch 7 is arranged on the base 11, used for controlling the start and stop of the rotating member 4; the user can conveniently control the rotation of the rotating member 4 through the control switch, so as to control the winding speed and times of the sealing film.

[0032] Use process:

[0033] Disinfection preparation: first, the device is subjected to ultraviolet radiation or ozone fumigation disinfection for standby, and then the outer surface of the device is disinfected with 75% alcohol before being moved to the corresponding position on the table top of the super-clean workbench.

[0034] Install the sealing film: put the sealing film roll of the corresponding width specification into the placing cylinder 6, and pull the first end of the sealing film out to the outside of the channel through the channel.

[0035] Fix the centrifugal tube: place the centrifugal tube to be sealed in the fixing member 2.

[0037] Complete winding: break the end of the sealing film, take out the sealed centrifugal tube, and place the next centrifugal tube to be sealed for operation in turn.

[0038] In summary, through the use of the centrifugal tube winding device of the present application, through the semi-automatic winding operation, the repeated manual labor of the sealing operation personnel is reduced, especially the work of maintaining the same posture for a long time, effectively avoiding the muscle and joint strain problems caused by continuous repeated actions, and protecting the health of the operation personnel; the design of the fixed number of winding ensures the consistency of the thickness of each winding, and ensures that the biological samples such as serum are in a sterile state.

[0039] Specifically, the center line of the rotating member 4 and the center line of the fixing member 2 are located on the same axis, and the output shaft of the rotating member 4 is an L-shaped structure, thereby ensuring that the rotating member 4 drives the support rod to rotate around the outer periphery of the centrifugal tube 3.

[0040] Specifically, when the rotating member 4 rotates, the extension part of the L-shaped output shaft can drive the support rod (and the channel and the sealing film thereon) to rotate around the outer periphery of the centrifugal tube.

[0041] Around the film operation:

[0042] In the around the film process, the fixed member 2 is used to fix the centrifugal tube, and the rotating member 4 drives the support rod and the channel to rotate through the L-shaped output shaft. With the rotation, the sealing film is gradually wound on the outer periphery of the centrifugal tube to form a tight seal.

[0043] On the basis of the above embodiment, the top end of the fixed member 2 is provided with a counterbore, the inner wall of the counterbore is provided with a rubber layer or a spring clamp, the rubber layer or the spring clamp is in interference fit with the centrifugal tube 3, and the opening of the counterbore is provided with a guide structure which is a tapered guide opening or an arc-shaped guide plate.

[0044] Specifically, the inner wall of the counterbore is provided with a rubber layer or a spring clamp, and the present application preferably uses a rubber layer. Due to the excellent elasticity and wear resistance of the rubber layer, it can well adapt to the slight unevenness of the surface of the centrifugal tube 3, and form an interference fit with the centrifugal tube 3 through elastic deformation, to ensure the tightness and stability of the connection.

[0045] In order to further simplify the assembly process of the centrifugal tube 3 and improve the assembly efficiency, the opening of the counterbore is provided with a guide structure which can be a tapered guide opening or an arc-shaped guide plate. The function is to guide and position when the centrifugal tube 3 is inserted into the counterbore, so that the centrifugal tube 3 can smoothly enter the counterbore and form an interference fit with the rubber layer or the spring clamp. The present application preferably uses a tapered guide opening.

[0046] That is, the height of the channel is slightly larger than the width of the sealing film, which can ensure that the sealing film moves freely and unobstructed in the channel, thereby smoothly completing the winding process.

[0047] On the basis of the above embodiment, the support rod 5 is connected with the output shaft of the rotating member 4 through a position adjusting member, which can adjust the height difference and spacing between the channel and the centrifugal tube 3. The position adjusting member includes a horizontal telescopic rod and a vertical telescopic rod. The head end of the horizontal telescopic rod is connected to the output shaft of the rotating member 4, the tail end is connected to the head end of the vertical telescopic rod, and the tail end of the vertical telescopic rod is connected to the top end of the support rod 5. The above horizontal telescopic rod and vertical telescopic rod are both existing mature technologies and have self-locking function.

[0048] That is, the use of the horizontal telescopic rod and the vertical telescopic rod can adjust the height difference and spacing between the channel and the centrifugal tube. It is very important to adapt to centrifugal tubes of different heights and sealing films of different thicknesses, which can ensure that the sealing film is tightly and uniformly wound on the centrifugal tube.

[0049] The self-locking function of the horizontal telescopic rod and the vertical telescopic rod means that after the position is adjusted, it can be firmly locked at the required position and will not move due to external factors (such as vibration, gravity, etc.).

[0050] On the basis of the above embodiment, the rotating member 4 is a rotary motor, and the workbench 1 further comprises a waste collecting box, which is arranged on the side of the base 11.

[0051] Specifically, the control end of the rotary motor has a function of presetting the number of rotation circles. After the start control switch 7 is started, the rotary motor will rotate according to the preset number of rotation circles and automatically stop after reaching the specified number of circles, ensuring the stability and consistency of each film winding operation.

[0052] The arrangement of the waste collecting box enables the waste generated in the film winding process to be conveniently collected, avoiding the scattering and accumulation of the waste, thereby maintaining the neatness and hygiene of the workbench.

[0053] It should be noted that in the present specification, relational terms such as first and second are used merely to distinguish one entity from another entity, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0054] The principle and implementation mode of the present application are described by using specific examples in the present specification, and the above embodiment is only used to help understand the method and core idea of the present application. It should be pointed out that for ordinary skilled persons in the art, without departing from the principle of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
