Description

Technical Field

[0001] This utility model relates to the field of biosafety cabinets, and more particularly to an emergency treatment device for chemotherapy drug spillage integrated into a biosafety cabinet. Background Technology

[0002] During the preparation and use of chemotherapy drugs, drug spills may lead to risks such as exposure of medical staff and environmental pollution. Traditional emergency response relies on manual operation and is inefficient. As a result, a chemotherapy drug spill emergency response device integrated into a biosafety cabinet has emerged. This device is mainly used in scenarios such as chemotherapy drug research and development workshops in pharmaceutical companies, and can quickly respond to spill events in the core operating space of the biosafety cabinet. Emergency response systems for chemotherapy drug spills integrated into biosafety cabinets typically consist of three parts: first, an intelligent detection module installed inside the cabinet that monitors drug leaks in real time via sensors; second, automatic adsorption and isolation components, such as liftable anti-diffusion baffles and highly absorbent materials, which prevent drug diffusion and initially adsorb the spilled drug; and third, a negative pressure collection system that draws residual drugs and contaminants into a sealed container through dedicated piping to prevent secondary contamination. The main function of this system is to shorten emergency response time, reduce the risk of human contact, and ensure that spilled drugs are collected and disposed of properly, further improving the safety and compliance of chemotherapy drug handling. Existing chemotherapy drug spill handling technologies largely rely on direct manual operation, lacking enclosed operating spaces and protective gloves, which easily leads to personnel contact with the drugs. Furthermore, the absence of dedicated locking and sealing structures allows volatile drug gases to easily diffuse, polluting the environment and posing health risks. Handling spills requires external storage and spraying equipment, making the process cumbersome. The lack of flow regulation and multi-angle spraying designs results in incomplete drug dilution and neutralization. The absence of a negative pressure exhaust system makes it difficult to remove harmful gases, and the dispersed functional components lead to slow emergency response and low handling efficiency. Therefore, a chemotherapy drug spill emergency handling device integrated into a biosafety cabinet is proposed to address these problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-2 An embodiment of this utility model provides a chemotherapy drug spill emergency handling device integrated into a biosafety cabinet, including a support frame 1, a box 2 fixedly connected to the top of the support frame 1, a pull pin assembly 3 fixedly connected to one side of the box 2, a cover plate 7 installed on the outer side of the top of the box 2, a partition 8 fixedly connected to the inner wall of the box 2, an exhaust fan 9 installed on the top of the partition 8, an exhaust pipe 10 installed on the top of the exhaust fan 9, a sliding groove 11 opened on the inner wall of the box 2, a front door 6 slidably connected to the inner wall of the support frame 1, a sealing port 5 fixedly connected to one side of the front door 6, and a glove 4 installed on the inner side of the box 2.

[0017] The support frame 1 provides stable support for the entire device, ensuring that the box 2 remains in a fixed position during operation. When chemotherapy drugs spill, staff can use gloves 4 inside the box 2 to reach into the device for emergency operations, avoiding direct contact with the drugs. The front door 6 can slide along the groove 11 on the inner wall of the box 2 to open and close the device. During the opening and closing process, the sealing port 5 and the front door 6 move synchronously to ensure the sealing of the box 2 and prevent spilled drugs from evaporating or spreading to the external environment. The cover plate 7 can cover the top of the box 2 to further enhance the sealing of the device. The partition 8 divides the interior of the box 2 into different functional areas. The vacuum pump 9 is installed on top of the partition 8. After starting, it can draw in any drug evaporation gases or residual pollutants that may be present in the box 2 through negative pressure, and then discharge them to the designated purification system through the exhaust pipe 10 to avoid leakage of harmful gases. Reference Figures 1-6 The pull pin assembly 3 includes a housing 23, which is fixedly connected to one side of the box 2. A locking block 22 is slidably connected to the inner wall of the housing 23. A pin 25 is fixedly connected to the middle of the locking block 22. A locking spring 24 is sleeved on the outside of the pin 25. A handle 26 is fixedly connected to one end of the pin 25.

[0018] The pull pin assembly 3 is mainly used to control the locking and unlocking of the front deflector 6. When it is necessary to close and lock the front deflector 6, push the handle 26 to drive the latch 25 to slide along the inner wall of the housing 23. The locking block 22 moves synchronously with the latch 25. At this time, the locking spring 24 is compressed and stores elastic potential energy. When the latch 25 is inserted into the corresponding locking position of the front deflector 6, release the handle 26. The locking spring 24 releases its elastic potential energy, pushing the locking block 22 and the latch 25 to reset, so that the latch 25 is stably locked in the locking position, thereby fixing the front deflector 6. When the front door 6 needs to be opened, pull the handle 26 again to overcome the spring force of the locking spring 24, causing the bolt 25 to be pulled out from the locked position, releasing the restriction on the front door 6 so that the front door 6 can slide open along the slide groove 11. The front door 6 is specially designed with a high-transparency anti-corrosion material. This material not only has excellent transparency to ensure clear and unobstructed vision, but also has excellent anti-corrosion properties, effectively resisting the erosion of the door body by various environmental factors, ensuring the stability and reliability of long-term use. Reference Figures 1-4 A water storage tank 14 is fixedly connected to one side of the tank body 2. A water pump 17 is installed inside the water storage tank 14. A pipe 15 is fixedly connected to the output end of the water pump 17.

[0019] The water tank 14 is used to store cleaning liquids required for emergency treatment. When chemotherapy drugs spill out, if it is necessary to dilute, neutralize or clean the spilled drugs, the water pump 17 is started. The water pump 17 uses its own power to extract the liquid in the water tank 14, and then transports the liquid to the subsequent spraying components through the pipe 15 connected to the output end, providing liquid support for the treatment of the drug spill area and ensuring that cleaning or neutralization operations can be carried out in a timely manner. Reference Figures 3-5 Pipe 15 is fixedly connected to a connecting pipe 18 at the end away from the water pump 17. An adjusting ball 19 is installed on the outside of the connecting pipe 18. A nozzle 21 is installed on the inside of the adjusting ball 19. An adjusting bracket 20 is installed on the outside of the nozzle 21. A bracket 12 is rotatably connected to both ends of the nozzle 21. A drive motor 16 is fixedly connected to the rear side of the housing 2. A rotating shaft 13 is fixedly connected to the output end of the drive motor 16. The bracket 12 is fixedly connected to the inner wall of the housing 2.

[0020] The liquid delivered from pipe 15 enters regulating ball 19 via connecting pipe 18. Regulating ball 19 can adjust the flow rate of the liquid by rotation to ensure that the spray volume meets the emergency treatment requirements. After passing through regulating ball 19, the liquid enters nozzle 21, which atomizes or sprays the liquid in a columnar shape to the area where the medicine overflows. Regulating frame 20 can fine-tune the spray angle of nozzle 21. Simultaneously, after the drive motor 16 starts, it drives the relevant components to rotate via rotating shaft 13, thereby causing nozzle 21 to rotate around the rotation points at both ends of bracket 12, achieving comprehensive spraying of different areas inside the box 2, ensuring that the overflowing medicine is fully diluted, neutralized, or cleaned, and avoiding medicine residue. Reference Figures 1-2 The glove 4 is snapped into the inside of the sealed port 5.

[0021] The glove 4 is connected to the sealed port 5 by a snap-fit ​​mechanism, which not only ensures a tight connection between the glove 4 and the sealed port 5 to prevent the leakage of drug vapors inside the box 2 from the connection, but also ensures that the glove 4 will not fall off the sealed port 5 when the operator is using the glove 4. At the same time, the snap-fit ​​structure facilitates the subsequent disassembly and replacement of the damaged glove 4, ensuring the continuous use of the device. Reference Figure 6 The pin 25 passes through the housing 2 and is slidably connected to the inside of the front door 6.

[0022] The pin 25 passes through the housing 2 and extends into the inside of the front door 6. Through the sliding connection with the front door 6, the front door 6 can be locked and unlocked. When the pin 25 slides along the inside of the front door 6 under the action of the pull pin assembly 3, the locking state can be flexibly switched. When locked, it can restrict the sliding of the front door 6 to ensure that the housing 2 is closed. When unlocked, it releases the restriction, making it easy for the front door 6 to open. Moreover, the structure that passes through the housing 2 can ensure the stability of the pin 25 during the movement process and avoid the displacement that would cause the locking to fail. ReferenceFigure 6 One end of the locking spring 24 is fixedly connected to the outside of the locking block 22, and the other end of the locking spring 24 is fixedly connected to the inner wall of the housing 23.

[0023] The locking spring 24 is connected to the locking block 22 and the housing 23 at both ends. When the latch 25 is pulled or pushed, the locking block 22 will move along the inner wall of the housing 23, causing the locking spring 24 to be compressed or stretched. The locking spring 24 stores elastic potential energy through deformation. When the external force disappears, the elastic potential energy is converted into kinetic energy, pushing the locking block 22 back to the initial position, thereby driving the latch 25 to reset, realizing the automatic locking of the front door 6 without the need for additional manual operation, improving the convenience of operation in emergency handling, while ensuring the stability of the locked state and preventing the latch 25 from being accidentally loosened due to vibration or other factors.

[0024] Working principle: When this chemotherapy drug spill emergency handling device integrated into the biosafety cabinet is in operation, the support frame 1 first provides stable support for the entire device, ensuring that the cabinet 2 remains in a fixed position. When chemotherapy drugs spill, personnel can use gloves 4, which are clipped to the inside of the sealed port 5, to reach into the cabinet 2 for emergency operations, avoiding direct contact with the drugs and preventing drug evaporation or diffusion. The cover 7 on the top outer side of the cabinet 2 further enhances the sealing. To lock the front door 6, push one end of the pin 25 in the pull-pin assembly 3. The handle 26 drives the pin 25 to slide along the inner wall of the housing 23. The locking block 22 moves synchronously with the pin 25, compressing and storing the elastic potential energy of the locking spring 24 sleeved on the outside of the pin 25. When the pin 25 passes through the housing 2 and slides to the locking position inside the front door 6, releasing the handle 26 releases the elastic potential energy of the locking spring 24, pushing the locking block 22 and the pin 25 to reset, thus automatically locking the front door 6. To unlock, pulling the handle 26 overcomes the elastic force of the locking spring 24 to pull out the pin 25. When handling spilled medicine, water is stored on one side of the housing 2. The water pump 17 inside the tank 14 starts, delivering the cleaning liquid inside the tank to the connecting pipe 18 through the output pipe 15. The liquid then enters the regulating ball 19 on the outside through the connecting pipe 18. The liquid flow rate can be controlled by rotating the regulating ball 19. Subsequently, the liquid enters the nozzle 21 inside the regulating ball 19, where it is atomized or sprayed in a columnar shape to the overflow area. At the same time, the spray angle can be finely adjusted by the adjusting bracket 20 on the outside of the nozzle 21. After the drive motor 16 on the rear side of the tank 2 starts, it drives the relevant components through the rotating shaft 13 at the output end. The operation causes the nozzles 21, which are rotatably connected to the support 12 at both ends, to rotate around the support 12, so as to achieve full spraying inside the box 2 to fully dilute and neutralize the drugs. In addition, the partition 8 fixedly connected to the inner wall of the box 2 divides the box into different functional areas. After the vacuum pump 9 at the top of the partition 8 is started, it draws in the drug volatile gases or residual pollutants in the box 2 through the negative pressure, and then discharges them to the designated purification system through the exhaust pipe 10 at the top of the vacuum pump 9, so as to avoid the leakage of harmful gases and finally complete the safe emergency treatment of chemotherapy drug spillage.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
