Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell culture technology, specifically to a fluid replenishment device for cell culture. Background Technology
[0002] Cell culture refers to a method of enabling organisms to survive, grow, reproduce, and maintain their main structures and functions by simulating the in vivo environment (sterility, suitable temperature, pH, and certain nutritional conditions) outside the body. Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technique. Whether for bioengineering as a whole or for biological cloning technology, cell culture is an indispensable process; cell culture itself is the large-scale cloning of cells. Cell culture technology can cultivate a single cell into a large number of simple single cells or minimally differentiated multicellular organisms, which is an essential step in cloning technology, and cell culture itself is cell cloning. Cell culture technology is an important and commonly used technique in cell biology research. Through cell culture, large numbers of cells can be obtained, and these cells can be used to study cell signal transduction, cellular synthesis and metabolism, cell growth and proliferation, etc.
[0003] When cells are cultured in traditional culture containers, it is often necessary to replenish the cells with nutrient solution. The traditional method is to manually add the liquid using a dropper. Some containers have been modified to add a replenishment device, eliminating the need for manual replenishment. However, this method increases equipment costs and the traditional culture containers are discarded, resulting in underutilization and waste. Therefore, we propose a replenishment device based on a circular bottle container. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0025] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0026] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0027] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.
[0028] In related technologies, the traditional method of replenishment is to manually add liquid using a dropper. Some containers have been modified to add liquid replenishment devices, eliminating the need for manual replenishment. However, this method increases equipment costs, and traditional culture containers are discarded, resulting in underutilization and waste.
[0029] To address some of the problems in the related technologies, this application provides a liquid replenishment device for cell culture. When needed, a container 13 is connected to the bottle opening 12 above the culture flask 11, and the valve 17 is manually controlled to replenish the liquid.
[0030] This application is described below with reference to the accompanying drawings and specific embodiments:
[0031] Combination Figures 1-3 This application provides a fluid replenishment device for cell culture, including a culture device 1; the culture device 1 includes: a culture flask 11 with a bottle mouth 12 at the top; a box body 13 disposed above the culture flask 11; a support plate 14 disposed at the bottom of the box body 13; a liquid inlet 15 disposed at the top of the box body 13; a fluid replenishment port 16 disposed at the bottom of the box body 13; and a valve 17 disposed at the bottom of the box body 13 and connected to the bottle mouth 12.
[0032] When using it, first put the cells and culture medium into the culture flask 11, and place the box 13 filled with replenishment medium on top of the culture flask 11. Then, connect the replenishment port 16 at the bottom of the box 13 with the bottle mouth 12 and put it into the incubator. When it is necessary to replenish the culture medium, open the valve 17 on the replenishment port 16, and then the liquid enters the culture flask 11 from the replenishment port 16 through the bottle mouth 12. The liquid replenishment is convenient and quick, and the box 13 can also act as the bottle cap of the culture flask 11.
[0033] In some embodiments, the housing 13 has a semi-cylindrical structure, and the liquid inlet 16 is located at the center of the housing 13. The housing 13 is configured as a semi-cylindrical structure, with the valve 17 extending out for easy rotation operation.
[0034] In some embodiments, an observation window 18 is provided on the outer side wall of the housing 13. The observation window 18 is for convenient observation of the liquid inside the housing 13, and then liquid is added from the liquid inlet 15 at the top.
[0035] In some embodiments, the culture device 1 is provided with an auxiliary component 2, which includes: a fixing plate 21 disposed on the outer side wall of the culture flask 11; and a rubber ring 22 disposed on the inner wall of the fixing plate 21. The fixing plate 21 is fitted onto the outer side wall of the culture flask 11 by the rubber ring 22, and is used to limit the position of the box body 13 and the support plate 14.
[0036] In some embodiments, the fixing plate 21 and the support plate 14 are threadedly connected. The threaded connection between the fixing plate 21 and the support plate 14 increases the stability of the support plate 14 and the housing 13.
[0037] In some embodiments, the outer walls of the liquid inlet 16 and the bottle mouth 12 are provided with vent holes 23. The vent holes 23 are for the convenience of the box body 13 replacing the cap with vent holes.
[0038] In some embodiments, a placement base 24 is provided below the support plate 14 to accommodate the liquid inlet 16. When not in use, the box 13 stands upright in the placement base 24 via the support plate 14 to prevent residual liquid from dripping from the liquid inlet 16.
[0039] In some embodiments, the interior of the placement base 24 is provided with absorbent cotton pads 25. The absorbent cotton pads 25 are for facilitating the absorption of residual liquid dripping from the replenishment port 16.
