[0026] 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.

[0027] The following is in conjunction with the appendix Figures 1 to 5 The specific embodiments of this utility model will be described in further detail.

[0028] Depend on Figures 1 to 5 As shown, this utility model includes a platform 1, with an operating table 2 fixedly connected to the front side of the platform 1. To facilitate the pouring of waste liquid during operation of the operating table, a connecting block 3 is fixedly connected to the left and right side walls of the platform 1. Each connecting block 3 has a first liquid discharge channel 4 inside, and each first liquid discharge channel 4 has a liftable baffle plate 5 inside. A collection bucket 6 is detachably connected to the lower side of each first liquid discharge channel 4. A negative pressure channel 7 for providing negative pressure to the inside of the first liquid discharge channel 4 is connected to the rear side of the first liquid discharge channel 4.

[0029] It should be noted that the platform 1 is a laminar flow hood, which is existing technology, such as the laminar flow hood model SJ-CJ-2F. This application does not improve the working principle of the laminar flow hood, but only makes relevant improvements to the support structure of the platform to meet the waste liquid collection requirements. Therefore, the working principle of the laminar flow hood will not be described in detail here. The operating platform 2 is the horizontal platform surface on the front side of the platform 1, which is used by the staff to perform operations on.

[0030] During use, staff can perform dust-free operations on the operating table 2. If waste liquid needs to be poured out during the work process, the baffle plate 5 can be raised to expose the first liquid discharge channel 4. At this time, the waste liquid can be poured directly into the first liquid discharge channel 4, and the waste liquid will enter the collection tank 6 through the first liquid discharge channel 4. During the process of pouring out the waste liquid, the negative pressure channel 7 will continuously provide a slight negative pressure to the inside of the first liquid discharge channel 4, reducing the probability of polluting aerosols inside the first liquid discharge channel 4 spreading to the operating table 2, thereby reducing pollution.

[0031] Furthermore, by Figures 1 to 5 As shown, in order to facilitate operation by staff, a support plate 8 is fixedly connected inside the first liquid channel 4. An electric push rod 9 is rotatably connected to the lower side of the support plate 8. A movable plate 10 is rotatably connected to the lower side of the electric push rod 9. The movable plate 10 is fixedly connected to the corresponding barrier plate 5.

[0032] It should be noted that the electric linear actuator 9 is existing technology. For example, the electric linear actuator 9 of model LX835 has its moving end connected to the moving plate 10, which will not be described in detail here.

[0033] Furthermore, by Figures 1 to 5 As shown, in order to make the opening and closing of the baffle plate 5 smoother, each first liquid channel 4 is provided with a baffle port 11 on the side near the operating table 2. The upper side of the baffle port 11 is connected to a first sliding groove 12, and the baffle plate 5 is slidably connected to the first sliding groove 12.

[0034] When it is necessary to raise the barrier plate 5, the electric push rod 9 can be activated to retract its moving end, and then the moving plate 10 will drive the barrier plate 5 to slide upward along the first sliding groove 12, thus raising the barrier plate 5 upward.

[0035] Furthermore, by Figures 1 to 5 As shown, in order to achieve a better sealing effect for the barrier plate 5, the barrier opening 11 is V-shaped with a wider top and a narrower bottom, and the bottom part is provided with rounded corners. A sealing strip 13 that is compatible with the barrier opening 11 is fixedly connected to the lower side of the barrier plate 5.

[0036] When in use, the sealing strip 13 is made of rubber. With the V-shaped design of the barrier opening 11, the barrier plate 5 can be tightly fitted to the barrier opening 11 under the action of the sealing strip 13, ensuring the airtightness of the barrier plate 5 to the barrier opening 11.

[0037] Furthermore, by Figures 1 to 5 As shown, in order to reduce the risk of biological contamination, a disinfection lamp 14 is fixedly connected to the lower side of the movable plate 10;

[0038] It should be noted that the disinfection lamp 14 is an ultraviolet disinfection lamp 14, which is existing technology and will not be described in detail here;

[0039] When in use, the disinfection lamp 14 is a normally open disinfection lamp 14, which can always disinfect the lower side of the moving plate 10. When the barrier plate 5 is open, the disinfection lamp 14 can meet the waste liquid dumping needs under the blocking effect of the barrier plate 5 without causing damage to the hands of the staff.

[0040] Furthermore, by Figures 1 to 5 As shown, to reduce the risk of biological contamination, the movable plate 10 has multiple ventilation holes 15, and the rear side wall of the operating platform 2 has a gas channel 16. Each negative pressure channel 7 is connected to the gas channel 16. The front side of the gas channel 16 has an installation port 17. Multiple negative pressure fans 18 are fixedly connected to the inner wall of the installation port 17, and a connecting sleeve 19 is fixedly connected to the front side of the installation port 17. The negative pressure fans 18 are miniature negative pressure ventilation fans, such as the miniature axial flow fan of model Lang C8020, which is existing technology and will not be described in detail here.

[0041] During use, as the baffle plate 5 rises, the negative pressure fan 18 will start simultaneously, drawing the gas inside the gas channel 16 and the negative pressure channel 7 outwards, ensuring that the aerosol inside the first liquid discharge channel 4 will not diffuse to the outside through the baffle port 11. Under the action of the vent 15, the air pressure on the upper and lower sides of the moving plate 10 inside the first liquid discharge channel 4 can be kept constant. Furthermore, a gas purification device is also connected to the outside of the mounting port 17 to further treat the extracted gas to render it harmless. The specific model of the air purification system can be selected according to the operation of the clean bench, and no further restrictions are imposed here.

[0042] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the collection of waste liquid, a second liquid channel 20 is provided on the left and right side walls of the operating table 2, which is connected to the bottom of the corresponding first liquid channel 4. A placement port 21 is connected to the lower side of the second liquid channel 20, and a placement plate 22 is fixedly connected to the bottom of the placement port 21. The collection bucket 6 is placed on the placement plate 22.

[0043] Furthermore, by Figures 1 to 5As shown, in order to ensure that the waste liquid will not cause secondary pollution, a second sliding groove 23 is provided on the inner top wall of the placement port 21. A sliding sleeve 24 is slidably connected inside the second sliding groove 23. A sealing cover 25 is fixedly connected to the bottom of the sliding sleeve 24. The sealing cover 25 has an opening in the middle for liquid to be discharged. A rubber strip 26 that matches the inner diameter of the collection tank 6 is fixedly connected to the lower side of the sealing cover 25. A liquid level sensor is also provided inside the collection tank 6. When there is too much liquid inside the collection tank 6, a buzzer alarm will be triggered.

[0044] In use, under the action of the rubber strip 26, the sealing cover 25 can seal the collection tank 6. The waste liquid poured out inside the first liquid discharge channel 4 will enter the collection tank 6 through the second liquid discharge channel 20 and the sealing cover 25. When it is necessary to treat the waste liquid inside the collection tank 6, the sealing cover 25 can be lifted up. At this time, the sliding sleeve 24 slides up along the second sliding groove 23, so that the sealing cover 25 is disengaged from the collection tank 6, and the collection tank 6 can be removed for pouring.

[0045] Furthermore, by Figures 1 to 5 As shown, in order to facilitate the operation of the staff, a fixed frame 27 is fixedly connected to each of the left and right sides of the lower side of the operating table 2, and a foot switch 28 is provided inside each fixed frame 27.

[0046] It should be noted that the foot switch 28 is existing technology, such as the foot switch with model number TFS201, which will not be described in detail here; in this embodiment, the electric telescopic rod and the negative pressure fan 18 are connected in parallel and then connected in series with the corresponding foot switch 28, and connected to the power module inside the platform 1. After the foot switch 28 is triggered by the operator's foot, the electric telescopic rod and the negative pressure fan 18 will move together, generating negative pressure and opening the barrier plate 5 at the same time.

[0047] When using this invention, workers can perform dust-free operations on the operating table 2. If waste liquid needs to be poured out during the work process, the baffle plate 5 can be raised to expose the first liquid discharge channel 4. At this time, the waste liquid can be poured directly into the first liquid discharge channel 4, and the waste liquid will enter the collection tank 6 through the first liquid discharge channel 4. During the process of pouring out the waste liquid, the negative pressure channel 7 will continuously provide a slight negative pressure to the inside of the first liquid discharge channel 4, reducing the probability of polluting aerosols inside the first liquid discharge channel 4 spreading to the operating table 2, thereby reducing pollution.

[0048] This utility model has a novel structure, ingenious design, and simple and convenient operation. This design effectively facilitates the pouring of waste liquid during operation on the workbench, makes the operation of the staff easier, makes the opening and closing of the barrier plate 5 smoother, achieves a better sealing effect, reduces the risk of biological pollution, and reduces the probability of the spread of polluting aerosols.

[0049] Although the present invention 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 invention should be included within the protection scope of the present invention.
