[0002] Cell culture is a technology that simulates the cell growth environment in vivo under in vitro conditions, and through providing suitable nutrition, temperature, gas and physical conditions, cells can grow, reproduce and carry out various physiological activities in a laboratory environment, and cell culture is an important technical means indispensable in modern biology, medicine and biotechnology research, and liquid waste that no longer has use value is easily produced in the cell culture process, which mainly includes old culture medium replaced in the cell culture process, cell metabolites, cell fragments and other possible pollutants, and a waste liquid collection device is needed to collect and process waste liquid during cell culture waste liquid collection, and its main function is to efficiently and safely collect and temporarily store waste liquid produced in the cell culture process, and to avoid waste liquid pollution of the laboratory environment and operating personnel.

[0003] The existing collection device usually uses a waste liquid cylinder to collect waste liquid during collection, and since the opening of the waste liquid cylinder is large, splashing occurs when pouring waste liquid, which pollutes the cell culture experiment and the environment, affects the accuracy of the experimental results, and the waste liquid cylinder has limited capacity, and for a large amount of waste liquid produced by large-scale cell culture experiments, the waste liquid cylinder needs to be frequently replaced, which is inconvenient to operate and can easily cause secondary pollution, increases the workload and operation risk of the experimental personnel.

[0004] Therefore, in view of the above-mentioned existing collection device, since the opening of the waste liquid cylinder is large, splashing occurs when pouring waste liquid, which pollutes the cell culture experiment and the environment, affects the accuracy of the experimental results, and the waste liquid cylinder has limited capacity, and the waste liquid cylinder needs to be frequently replaced, which is inconvenient to operate and can easily cause secondary pollution, increases the workload and operation risk of the experimental personnel, a cell culture waste liquid collection device can be designed, the bottle opening is installed in a non-horizontal manner, and the two sides are different in height, so that the waste liquid can smoothly flow into the bottle body during pouring, waste liquid overflow caused by liquid surface tension or improper pouring angle is avoided, and the accuracy of the experimental results is ensured. SUMMARY

[0005] In order to overcome the problem that the existing collection device is prone to splashing when pouring waste liquid, which pollutes the cell culture experiment and the environment, and affects the accuracy of the experimental results.

[0006] The technical solution of this utility model is as follows: a cell culture waste liquid collection device, including a bottle body, a cap, a bottle mouth, a splash guard, a drain pipe and a flow meter. The cap is installed at the upper end of the bottle body, and the bottle mouth is provided above the cap. The outer wall of the bottle mouth is fitted with a splash guard. One end of the bottle mouth is the cup mouth guide side, and the side of the bottle mouth away from the cup mouth guide side is the overflow prevention side.

[0007] Preferably, the upper end of the cap is connected to a bottle neck, which is fixedly connected to the bottle mouth, and the lower end of the cap is fixed with a sealing strip, which seals the cap to the bottle body.

[0008] Preferably, the lower interior of the bottle is provided with a sloping plate, which is fixedly connected to the bottle body.

[0009] Preferably, a threaded head is fixed to the outer end of the bottle body, the threaded head is connected to the bottle body, a drain pipe is sleeved on the outer end of the threaded head, the drain pipe is threadedly fixed to the threaded head, and a sealing ring is installed inside the threaded head.

[0010] Preferably, the outer end of the drain pipe is fixed with a connector, and a valve is installed at one end of the connector.

[0011] Preferably, a flow meter is installed on the outside of the bottle body, and a detection rod is installed at one end of the flow meter. The detection rod passes through the cap and extends into the inside of the bottle body. Several sets of rubber clips are installed on the outer end of the bottle body, and the flow meter is fixed to the bottle body by several sets of rubber clips.

[0012] Preferably, a support plate is fixed to the lower end of the bottle body, and several sets of anti-slip blocks are provided circumferentially at the lower end of the support plate.

[0013] The beneficial effects of this utility model are:

[0014] Compared to traditional waste liquid collection devices, this method involves installing the bottle opening at different heights on both sides. Using the cup-mouth guide side and the overflow prevention side, along with a splash guard to support the container during waste liquid pouring, ensures accurate alignment with the bottle opening. This allows the waste liquid to flow smoothly into the bottle during pouring, preventing overflow due to liquid surface tension or improper pouring angle. This guarantees the accuracy and reliability of experimental results. Furthermore, the relatively narrow bottle neck and the gentle, smooth slope of the curved surface connecting the cup-mouth guide side and the bottle neck allow water to flow slowly down the slope, preventing splashing of waste liquid upon impact during pouring. This reduces the risk of laboratory and environmental pollution and provides favorable conditions for cell culture. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment: a cell culture waste liquid collection device, including a bottle body 1, a cap 2, a bottle mouth 4, a splash guard 5, a drain pipe 6 and a flow meter 10. The cap 2 is installed on the upper end of the bottle body 1, and the bottle mouth 4 is provided above the cap 2. The outer wall of the bottle mouth 4 is fitted with a splash guard 5. One end of the bottle mouth 4 is the cup mouth guide side, and the side of the bottle mouth 4 away from the cup mouth guide side is the overflow prevention side.

[0022] Please see Figures 1-3 In this embodiment, the upper end of the cap 2 is connected to a bottleneck 3, which is fixedly connected to the bottle mouth 4. The lower end of the cap 2 is fixed with a sealing strip 9. The cap 2 is sealed to the bottle body 1 by the sealing strip 9. The bottleneck 3 narrows the bottle mouth 4, and the curved surface connecting the cup mouth guide side and the bottleneck 3 has a gentle and smooth slope, which allows the water to flow slowly down the slope, preventing the waste liquid from splashing due to impact when it is poured, and reducing the risk of laboratory contamination. The lower end of the inside of the bottle body 1 is provided with an inclined plate 12, which is fixedly connected to the bottle body 1. By gradually thinning the inclined plate 12 towards the drain outlet, the waste liquid is guided to flow along the surface of the inclined plate 12, so that the waste liquid flows naturally to the drain outlet under the action of gravity, ensuring that the waste liquid can be discharged smoothly and reducing the residue of waste liquid in the bottle body 1.

[0023] Please see Figures 2-3In this embodiment, a threaded head 7 is fixed to the outer end of the bottle body 1. The threaded head 7 is connected to the bottle body 1. A drain pipe 6 is sleeved on the outer end of the threaded head 7. The drain pipe 6 is threadedly fixed to the threaded head 7. A sealing ring is installed inside the threaded head 7. By using the sealing ring to assist the threaded head 7 in sealing the connection with the drain pipe 6, the leakage of waste liquid at the connection is effectively prevented, ensuring the sealing of the waste liquid discharge process and ensuring the stable discharge of waste liquid. A connector is fixed to the outer end of the drain pipe 6. A valve 8 is installed at one end of the connector. By using the valve 8, the discharge of waste liquid is precisely controlled. The drain pipe 6 can be opened or closed as needed to avoid too much or too little waste liquid discharge, prevent waste liquid backflow, and improve operational safety.

[0024] Please see Figures 2-4 In this embodiment, a flow meter 10 is provided on the outside of the bottle body 1. A detection rod is installed at one end of the flow meter 10. The detection rod extends through the cap 2 into the inside of the bottle body 1. Several sets of rubber clips 11 are installed on the outer end of the bottle body 1. The flow meter 10 is fixed to the bottle body 1 by several sets of rubber clips 11. By using the flow meter 10 to assist in detecting the waste liquid collected inside the bottle body 1, the amount of waste liquid collected in real time is monitored, providing accurate data support for operators, preventing spills and contamination, and reducing the risk of laboratory contamination. A support plate 13 is fixed at the lower end of the bottle body 1. Several sets of anti-slip blocks are provided circumferentially at the lower end of the support plate 13. By using the support plate 13 in combination with several sets of anti-slip blocks to assist in supporting the bottle body 1, the waste liquid bottle is effectively fixed and the waste liquid is collected stably, preventing it from tilting or tipping over due to liquid shaking or external force during the suction process, thus improving the overall stability.

[0025] During operation, first, place the bottle body 1 in the designated collection position. Use the support plate 13 combined with several sets of anti-slip blocks to support the bottle body 1, fixing the waste liquid bottle for stable collection. Use the sealing strip 9 to fasten the cap 2 to the bottle body 1 for sealing, facilitating the subsequent removal of the cap 2 for overall cleaning of the bottle body 1. Next, thread the drain pipe 6 to the threaded head 7. When the drain pipe 6 is installed to collect waste liquid, close the valve 8. Position the container bottle, supported by the splash ring 5, aligned with the bottle mouth 4. The bottle mouth 4 is installed non-horizontally, with different heights on both sides. Use the cup mouth guide side and the overflow prevention side to ensure that the waste liquid flows smoothly into the bottle body 1 during pouring, avoiding overflow due to liquid surface tension or improper pouring angle, and reducing contact between the waste liquid and the external environment. Combined with the relatively narrow bottle mouth 4 due to the neck 3, and the curved connection surface between the cup mouth guide side and the neck 3, the waste liquid is effectively collected. The gentle slope allows water to flow slowly down the slope, preventing splashing of waste liquid during dumping and reducing the risk of laboratory and environmental pollution. This provides favorable conditions for cell culture. Once the waste liquid has been collected and stabilized, the flow meter 10 can assist in detecting the waste liquid collected inside the bottle 1, monitoring the collection volume in real time, and providing accurate data support for operators. When the waste liquid reaches the specified level, the inclined plate 12 gradually thins towards the drain pipe 6, guiding the waste liquid to flow along the surface of the inclined plate 12. Under gravity, the waste liquid flows naturally to the drain outlet. When it is necessary to drain the waste liquid completely for cleaning the bottle 1, the valve 8 is opened in conjunction with the inclined plate 12 to ensure smooth discharge of the waste liquid, reducing the residue of waste liquid in the bottle 1. The sealing ring inside the threaded head 7 fits the drain pipe 6 to prevent leakage of waste liquid at the connection, ensuring stable discharge of waste liquid and facilitating the cleaning of the bottle 1.

[0026] Through the above steps, by installing the bottle opening 4 at different heights on both sides, and using the cup opening guide side and the anti-overflow side to assist in supporting the container bottle when pouring waste liquid, combined with the anti-splash ring 5, it is ensured that the bottle opening 4 can be accurately aligned. This allows the waste liquid to flow smoothly into the bottle body 1 during the pouring process, avoiding waste liquid overflow caused by liquid surface tension or improper pouring angle, thus ensuring the accuracy and reliability of experimental results. Combined with the fact that the bottle opening 4 is relatively narrower due to the bottleneck 3, and the smooth and gentle slope of the curved surface connecting the cup opening guide side and the bottleneck 3, the water can flow slowly down the slope, preventing the waste liquid from splashing due to impact when pouring, reducing the risk of laboratory and environmental pollution, and providing favorable conditions for cell culture.
