[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 7 As shown in the embodiment of the present invention, a multi-chamber thoracentesis and drainage device for thoracic surgery includes a transparent shell 1, a water storage shell 11 on one side of the transparent shell 1, an air outlet 111 at the top of the water storage shell 11, a sterile gauze 112 inside the air outlet 111, two fluid collection tanks 3 inside the transparent shell 1, a puncture needle 2 above the transparent shell 1, a drainage tube 21 fixed to one end of the puncture needle 2, an exhaust hose 141 inside the water storage shell 11, one end of the exhaust hose 141 being able to communicate with the fluid collection tank 3, and the other end of the exhaust hose 141 being inserted into the water inside the water storage shell 11;

[0035] The other end of the drainage tube 21 is provided with a connecting component, which can communicate with one of the liquid collection tanks 3. A micro motor 12 is installed at the bottom of the transparent shell 1. Two rollers 121 are rotatably connected inside the transparent shell 1. A movable plate 123 is sleeved on the outside of the two rollers 121. The movable plate 123 can be locked on the outside of the liquid collection tank 3. Mounting brackets 132 are provided on both sides inside the transparent shell 1. An infrared transmitter and an infrared receiver are respectively installed on one side of the two mounting brackets 132. One of the liquid collection tanks 3 is placed between the infrared transmitter and the infrared receiver. A distance sensor is also installed on one of the mounting brackets 132.

[0036] When the infrared receiver fails to receive the signal from the infrared transmitter, the micro motor 12 is activated to drive the moving plate 123 to push the liquid collection tank 3 for replacement.

[0037] During thoracic surgery, patients may experience pleural effusion, resulting in high pressure within the cavity. This necessitates drainage of the fluid, requiring the use of a drainage device. To use this device, the staff picks up the puncture needle 2 and inserts its tip into the pleural effusion area. The transparent housing 1 is then fixed to the bed. Under the pressure within the pleural cavity, the effusion drains through the puncture needle 2 into the drainage tube 21. The drainage tube 21 then drains the effusion into the effusion container 3 via a connecting assembly. Simultaneously, air inside the liquid collection tank 3 is discharged into the water inside the water storage shell 11 through the exhaust hose 141. This air is filtered by the water and discharged through the air outlet 111. The sterile gauze 112 inside the air outlet 111 filters the air that needs to be discharged. The water inside the water storage shell 11 also seals the port of the exhaust hose 141, preventing external air from entering the liquid collection tank 3. During the drainage process, the infrared transmitter and receiver begin to operate. When the liquid level inside the liquid collection tank 3 reaches the positions of the infrared transmitter and receiver, the infrared... The receiver's light reception capacity decreases, and the liquid collection tank 3 is about to fill up, requiring replacement. At this point, the micro motor 12 is triggered, starting and rotating the roller 121. The roller 121 then rotates the conveyor belt 122, which in turn moves the moving plate 123. The moving plate 123 pushes the spare liquid collection tank 3 towards the center of the transparent housing 1. Simultaneously, the connecting component disconnects from the full liquid collection tank 3. Pushed by the spare liquid collection tank 3, the full liquid collection tank 3 moves to the other side. Meanwhile, the distance sensor monitors the liquid collection tank 3 in real time. When the liquid-filled collection tank 3 is pushed, the distance sensor detects the increase in distance and the backup collection tank 3 moves toward the distance sensor. When it moves to the distance sensor, the distance sensor detects the backup collection tank 3 and controls the micro motor 12 to stop rotating at the closest position. The connecting component reconnects with the backup collection tank 3 for use. At this time, the collection tank 3 can be automatically replaced, which can avoid the situation where the staff cannot know the contents of the collection tank 3 in time, resulting in the inability to drain the liquid normally. In addition, if the backup collection tank 3 is not used, it can be taken out and used for other devices.

[0038] like Figures 1 to 5 As shown, bottom limiting plates 13 are fixed on both sides of the bottom of the transparent shell 1. The liquid collection tank 3 slides between the bottom limiting plates 13. Top limiting plates 131 are fixed on both sides of the upper part of the transparent shell 1. The top limiting plates 131 are fixedly connected to the mounting bracket 132. A connector 31 is fixed on the top of the liquid collection tank 3. The two top limiting plates 131 can guide the connector 31.

[0039] When the liquid collection tank 3 moves inside the transparent shell 1, in order to ensure that the spare liquid collection tank 3 can push the liquid collection tank 3 filled with liquid, it is necessary to guide the movement direction of the liquid collection tank 3. Therefore, a bottom limiting plate 13 is set to guide the bottom end of the liquid collection tank 3, so that the liquid collection tank 3 can move horizontally inside the transparent shell 1. At the same time, the top limiting plate 131 can guide the connector 31. The two sides of the connector 31 are close to the top limiting plate 131. When the liquid collection tank 3 moves, it can ensure that the angle of the connector 31 will not change, which makes it easier for the connecting components to connect with the connector 31.

[0040] like Figures 1 to 8 As shown, the connecting assembly includes a fixing block 14 fixed to the top of the inside of the transparent shell 1. An insertion tube 151 passes through the inside of the fixing block 14. A lifting plate 15 is fixed to the bottom of the insertion tube 151. One side of the inside of the lifting plate 15 is connected to the drainage tube 21, and the other side of the inside of the lifting plate 15 can be connected to the exhaust hose 141. An inlet pipe 32 and an exhaust port 33 are respectively provided on both sides of the inside of the connector 31. The inlet pipe 32 can be connected to the drainage tube 21, and the exhaust port 33 can be connected to the exhaust hose 141. A lifting frame 152 is fixed to the top of the insertion tube 151. A rotating hole is opened on the other side of the lifting frame 152. A protrusion 155 is fixed inside the rotating hole. A connecting shaft 124 is fixed to the top of one of the rollers 121. A rotating column 125 is fixed to the top of the connecting shaft 124. A spiral groove 126 is opened on the outside of the rotating column 125. The protrusion 155 can be slidably connected to the inside of the spiral groove 126.

[0041] When replacing the spare liquid collection tank 3, in the initial state, the protrusion 155 is at the bottom of the spiral groove 126. The micro motor 12 drives the roller 121 to rotate, the roller 121 drives the connecting shaft 124 to rotate, the connecting shaft 124 drives the rotating column 125 to rotate, and the rotating column 125 drives the spiral groove 126 to rotate. Under the guidance of the spiral groove 126, the protrusion 155 will cause the lifting frame 152 to move upward. At the same time, the lifting frame 152 pulls up the lifting plate 15 and separates it from the connector 31 through the insertion tube 151. There is a distance between the spare liquid collection tank 3 and the liquid collection tank 3 below the lifting plate 15. When the lifting plate 15 separates from the connector 31, the spare liquid collection tank 3 contacts the liquid collection tank 3 below the lifting plate 15, which will not cause interference between the two liquid collection tanks 3. After the liquid collection tank 3 is replaced, the micro motor 12 is started to drive the roller 121 to rotate in the opposite direction. At this time, the rotating column 125 drives the protrusion 155 to move downward through the spiral slide 126. The protrusion 155 drives the lifting plate 15 to move downward through the lifting frame 152 and cover the top of the connector 31. At this time, the drainage pipe 21 is connected to the liquid inlet pipe 32, and the exhaust hose 141 is connected to the exhaust port 33, which makes it easier to replace the liquid collection tank 3.

[0042] like Figures 1 to 8 As shown, an annular groove 127 is provided on the outside of the rotating column 125 above the spiral groove 126, and the protrusion 155 can be slidably connected to the annular groove 127.

[0043] When the protrusion 155 rotates to the top of the spiral groove 126, the roller 121 will continue to rotate to drive the liquid collection tank 3 to be replaced. At this time, the spiral groove 126 will get stuck on the protrusion 155. Therefore, an annular groove 127 is provided at the top of the spiral groove 126. After the protrusion 155 moves into the inside of the annular groove 127, it can rotate horizontally inside the annular groove 127, so that the roller 121 can continue to rotate to drive the liquid collection tank 3 to move.

[0044] like Figures 1 to 8 As shown, a first spring 154 is fixed to the top of the lifting frame 152, and a support shell 153 is sleeved on the outside of the lifting frame 152. The top of the first spring 154 is fixedly connected to the first spring 154.

[0045] When the lifting frame 152 rises, it will compress the first spring 154. When the rotating column 125 rotates in the opposite direction, the elastic force of the first spring 154 will push the lifting frame 152. The lifting frame 152 will press the protrusion 155 downward. At this time, it is convenient for the protrusion 155 to slide from the inside of the annular slide groove 127 into the inside of the spiral slide groove 126, so as to prevent the protrusion 155 from failing to slide into the spiral slide groove 126, which would cause the lifting plate 15 to fail to be fixed with the connector 31.

[0046] like Figures 1 to 7 As shown, a sliding hole 142 is provided inside the fixed block 14, and a telescopic tube 156 is fixed on one side of the top of the lifting plate 15. The telescopic tube 156 is slidably connected to the sliding hole 142.

[0047] During the movement of the lifting plate 15, in order to ensure the connection between the inside of the lifting plate 15 and the exhaust hose 141, a telescopic tube 156 is slidably connected to the sliding hole 142. When the lifting plate 15 is raised or lowered, it will drive the telescopic tube 156 to rise or fall inside the sliding hole 142, thereby keeping the exhaust hose 141 connected to the lifting plate 15 at all times, so as to facilitate the connection between the exhaust port 33 and the exhaust hose 141.

[0048] like Figures 1 to 8 As shown, two insertion tubes 151 are fixed at the bottom of the lifting plate 15. The two insertion tubes 151 are respectively connected to the inside of the drainage tube 21 and the telescopic tube 156. The two insertion tubes 151 can be inserted into the inside of the liquid inlet tube 32 and the exhaust port 33.

[0049] When the lifting plate 15 needs to be connected to the inlet pipe 32 and the vent 33, when the lifting plate 15 is covered on the top of the connector 31, the two inserts 151 are inserted into the inlet pipe 32 and the vent 33, thereby connecting the lifting plate 15 with the inside of the connector 31.

[0050] like Figures 1 to 8 As shown, sliding cavities 311 are provided on both sides of the top of the connector 31. A pair of baffles 312 are provided inside the sliding cavity 311. The two pairs of baffles 312 cover the top of the liquid inlet pipe 32 and the exhaust port 33 respectively. A second spring 313 is fixed on both sides of the baffle 312. The other end of the second spring 313 is fixed to the inside of the sliding cavity 311. A slope is provided on one side of the top of the baffle 312. Sloping surfaces are provided on both sides of the bottom of the insertion tube 151.

[0051] To ensure the sealing of the liquid collection tank 3, two sets of baffles 312 are installed to block the inlet pipe 32 and the vent 33. When the lifting plate 15 needs to connect with the connector 31, the lifting plate 15 moves the insertion tube 151 towards the top of the connector 31. At this time, the insertion tube 151 is inserted into the inlet pipe 32 and the vent 33. The inclined surface of the insertion tube 151 contacts the inclined surface of the baffle 312. At this time, the baffle 312 can be pushed to both sides. At the same time, the baffle 312 squeezes the second spring 313. When the connector 31 is separated from the lifting plate 15, the elastic force of the second spring 313 drives the baffle 312 to automatically reset, so that the baffle 312 can automatically block the inlet pipe 32 and the vent 33, thereby preventing the liquid inside the liquid collection tank 3 from leaking out.

[0052] like Figures 1 to 9 As shown, a connecting frame 114 is fixed to one end of the exhaust hose 141 inside the water storage shell 11, and multiple floats 113 are fixed to the top of the connecting frame 114.

[0053] During use, the installation position of the transparent shell 1 may not be horizontal, which will cause the horizontal plane inside the water storage shell 11 to tilt. The water inside the water storage shell 11 needs to rely on the water level to prevent air from flowing backward. Therefore, a connecting bracket 114 is fixed to the end of the exhaust hose 141, and a float ball 113 is fixed to the top of the connecting bracket 114. The float ball 113 floats on the water surface. Therefore, when the water storage shell 11 tilts or the water level drops due to evaporation during use, the float ball 113 can automatically adapt to the current water level, thereby keeping the depth of the exhaust hose 141 in the water stable and avoiding changes in depth from affecting the exhaust of the exhaust hose 141 and preventing air from entering.

[0054] like Figures 1 to 9 As shown, a conical frame 115 is fixed to the bottom end of the connecting frame 114, and the bottom end of the conical frame 115 can contact the inner wall of the water storage shell 11.

[0055] When the float 113 floats, it may float to the edge of the water storage shell 11 due to its tilt, causing the vent hose 141 to be in the shallow water area, which will affect the filtration effect of the water flow inside the water storage shell 11. Therefore, a conical frame 115 is set up. The conical frame 115 is in the water. When the float 113 floats in the shallow water area of ​​the water storage shell 11, the bottom end of the conical frame 115 will contact the inclined inner wall of the transparent shell 1. Under the guidance of the inclined inner wall, the conical frame 115 slides and drives the connecting frame 114. The connecting frame 114 drives the float 113 to move to the deep water area, thereby keeping the vent hose 141 in the deep water area.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
