DETAILED DESCRIPTION

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0037] like Figures 1 to 13 The device is a pleural effusion drainage nursing device for thoracic surgery patients, comprising a bottle body 1, a top cover 2 is fixedly connected to the top of the bottle body 1, a connecting tube 3 is fixed to the top of the top cover 2, a connecting tube 3 is installed inside the connecting tube 3, and the connecting tube 3 is used for connecting the external drainage tube;

[0038] An opening 4 is formed through the top of the top cover 2, and the connecting pipe 3 is connected to the opening 4. The inner circle of the opening 4 is rotatably connected to a first ring 5. The bottom end of the first ring 5 passes through the opening 4 and is located below the top cover 2. An air outlet 6 is formed symmetrically through the top of the top cover 2. A cavity 7 is formed inside the top cover 2. Both the two air outlets 6 and the opening 4 are connected to the cavity 7. An opening and closing mechanism is installed inside the cavity 7. The opening and closing mechanism is used to control the opening and closing of the two air outlets 6.

[0039] A rotating mechanism is installed inside the cavity 7. When the bottle body 1 is tipped over, the rotating mechanism is used to drive the first ring 5 to rotate. A discharging mechanism is fixedly installed at the bottom of the first ring 5. When the bottle body 1 is tipped over, the discharging mechanism is used to keep the discharging end below the liquid level inside the bottle body 1. A tipping detection sensor 11 is fixed on the inner wall of the cavity 7. A battery 12 is installed on the inner wall of the cavity 7. During operation, since the patient turns over during deep sleep, it is easy to pull the water seal bottle and cause the water seal bottle to tip over. At the same time, if the medical staff is not present, the water seal bottle will not tip over after it tips over. It can be handled in time. There is a situation where the drainage tube is separated from the liquid surface and connected to the air, and the liquid in the water seal bottle flows out of the bottle. The entry of air into the drainage tube may cause bacterial infection, which may cause serious complications. The outflow of effusion will affect the doctor's test results of the effusion. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. First, the medical staff inserts the drainage tube through the connecting tube 3 into the inside of the first ring 5, and then the medical staff fixes the drainage tube through the clamping mechanism, which is helpful to prevent the drainage tube from being pulled when the bottle body 1 is pulled. Pull out the bottle 1. During use, the patient's pleural effusion, under the action of gravity and the patient's breathing, flows along the drainage tube through the connecting tube 3 into the interior of the first ring 5, and then is discharged into the bottle 1 along the discharging mechanism. When the bottle 1 is not tipped over, the discharging mechanism remains in a vertical state under the action of gravity and falls below the liquid level inside the bottle 1. After the bottle 1 is tipped over due to external force, the tipping detection sensor 11 provided can sense the direction in which the bottle 1 is tipped, and then control the opening and closing mechanism to close the air outlet 6 in the tipping direction to prevent the bottle 1 from tipping over. To stop the accumulated liquid from flowing out, the air outlet 6 away from the tipping direction is located at the top after the bottle body 1 is tipped over. The rotation angle of the first ring 5 can be adjusted by the rotating mechanism, so that the discharging mechanism can swing along the tipping direction. After the bottle body 1 is tipped over, under the action of gravity, the bottle body 1 drives the discharging mechanism to rotate, so that the discharging mechanism can adjust the direction after rotation, and keep the discharging end below the liquid level inside the bottle body 1 under the action of gravity, which is beneficial to prevent air from entering the patient's chest cavity, so that the bottle body 1 can still be used normally after being tipped over.

[0040] As an embodiment of the present invention, the clamping mechanism includes a first annular groove 13 and a second annular groove 14. The first annular groove 13 is provided on the inner ring of the receiving tube 3. A sealing ring is fixed at the edge of the groove of the first annular groove 13. Four arc plates 15 are slidably connected inside the first annular groove 13. The four arc plates 15 are threadedly connected with threaded rods 16 through threaded holes. The second annular groove 14 is provided on the outer wall of the receiving tube 3. Four openings 17 are provided in a circumferential array on the inner wall of the first annular groove 13. The first annular groove 13 is connected with the second annular groove 14 through the four openings 17. A driving ring 18 is slidably connected inside the second annular groove 14. A first bevel gear 19 is fixed on the top of the driving ring 18. The four threaded rods 16 respectively pass through the openings 17 and extend to the inside of the second annular groove 14, where a second bevel gear 20 is fixed. The four second bevel gears 20 are meshed with the first bevel gear 19. The four threaded rods 16 are respectively engaged with the four openings 17. 7 Rotational connection; during operation, after the medical staff inserts the drainage tube through the connecting tube 3 into the interior of the first circular ring 5, the medical staff rotates the driving ring 18, and the driving ring 18 drives the first bevel gear 19 to rotate, and the first bevel gear 19 is meshed with the second bevel gear 20, and the first bevel gear 19 drives the four second bevel gears 20 to rotate, and the four second bevel gears 20 all drive the threaded rod 16 fixedly connected thereto to rotate, and the rotation of the four threaded rods 16 drives the arc plate 15 threadedly connected thereto to move, and the four arc plates 15 move to clamp the drainage tube in the center, so as to prevent the patient from turning over and pulling the drainage tube so that the drainage tube is separated from the bottle body 1, so as to prevent the air from entering the patient's chest cavity from the pulled-out drainage tube, so as to facilitate the patient to perform effective pleural effusion drainage treatment, and the notch edge of the first annular groove 13 is fixed with a sealing ring, so as to improve the sealing performance and reduce the possibility of external air entering the drainage tube from the connecting tube 3.

[0041] As an embodiment of the present invention, the opening and closing mechanism includes two first electric telescopic rods 21, which are respectively fixedly connected to two opposite side walls of the cavity 7. Sliders 22 are fixed to the telescopic ends of the two first electric telescopic rods 21. Both sliders 22 are flexible rubber sliders, and both sliders 22 are slidably connected to the cavity 7. The two sliders 22 respectively match the two air outlets 6. Sealing components are installed on one side of the two air outlets 6 facing each other. The sealing components are used to seal the air outlets 6 after the sliders 22 block the air outlets 6. The sealing components are located inside the cavity 7. During operation, after the bottle body 1 is tilted, according to the tilt detection sensor 11, the tilting direction of the bottle body 1 can be detected, and then the corresponding first electric telescopic rod 21 is started. The first electric telescopic rod 21 extends to drive the slider 22 to move, and the slider 22 moves to block the air outlet 6 located below after the bottle body 1 is tilted, which is beneficial to preventing the liquid accumulation from draining out of the lower air outlet 6 after the bottle body 1 is tilted. Through the provided sealing components, the sealing performance between the air outlet 6 and the slider 22 can be increased, which is beneficial to preventing the liquid accumulation from seeping out of the air outlet 6.

[0042] As an embodiment of the present invention, the sealing component includes a fixed rod 23 and a limit plate 24. The fixed rod 23 is fixedly connected to the inside of the cavity 7. An inclined plate 25 is rotatably connected to the outer circle of the fixed rod 23. The inclined plate 25 is located at the edge of the air outlet 6. The limit plate 24 is fixedly connected to the inside of the cavity 7. A telescopic rod 26 is fixed to one side of the limit plate 24 close to the inclined plate 25. A sliding pin 27 is fixed to the telescopic end of the telescopic rod 26. A relief groove 28 is formed on one side of the inclined plate 25 facing the limit plate 24. The sliding pin 27 is slidably connected to the relief groove 28. A baffle 29 is fixed to the outer circle of the telescopic end of the telescopic rod 26. A spring 30 is sleeved on the outer circle of the telescopic rod 26. One end of the spring 30 is fixedly connected to the limit plate 24, and the other end of the spring 30 is fixedly connected to the baffle 29. During operation, during the process of the telescopic end of the first electric telescopic rod 21 extending to drive the slider 22 to move, the slider 22 abuts against the inclined plate 25, and during the continuous movement of the slider 22, the slider 22 presses the inclined plate 25 to make the inclined plate 25 rotate around the fixed rod 23. The rotation of the inclined plate 25 makes the distance between the inclined plate 25 and the limit plate 24 smaller, so that the inclined plate 25 can push the telescopic rod 26 to expand and contract to drive the baffle 29 to press the spring 30. After the slider 22 completely blocks the air outlet 6, under the elastic force of the spring 30, the inclined plate presses against one side of the slider 22. Because the slider 22 is made of rubber material, the slider 22 will deform under the extrusion of the spring 30, which can make the slider 22 and the air outlet 6 closer, which is beneficial to increasing the sealing performance between the slider 22 and the air outlet 6, and is beneficial to preventing the occurrence of liquid accumulation seepage.

[0043] As an embodiment of the present invention, the rotation mechanism includes a second electric telescopic rod 31 and a gear 32. The second electric telescopic rod 31 is fixed to the side wall of the cavity 7, and a rack 35 is fixed to the telescopic end of the second electric telescopic rod 31. The gear 32 is fixed to the outer ring of the first ring 5, and the gear 32 meshes with the rack 35. During operation, after the bottle body 1 is detected to be tilted by the tilt detection sensor 11, taking Figure 1 the position shown as a reference, when the bottle body 1 tilts to the left or right, the second electric telescopic rod 31 is not activated. After the bottle body 1 tilts, the hollow rod 9 rotates around the pin 33 and swings downward under the action of gravity, so that the discharge end of the discharge mechanism is inserted below the liquid level and is not connected to the outside air. When the bottle body 1 tilts forward or backward, the second electric telescopic rod 31 is activated. The second electric telescopic rod 31 can drive the rack 35 to move. During the movement of the rack 35, it can drive the gear 32 to rotate. The rotation of the gear 32 can drive the first ring 5 to rotate. The first ring 5 can drive the discharge mechanism to rotate, so that after the bottle body 1 tilts, the position of the discharge mechanism can be adjusted, and after the position of the discharge mechanism is adjusted, it can cooperate with the action of gravity to drive the discharge mechanism to bend, which is beneficial to the discharge mechanism still being below the liquid level and not communicating with the air after the bottle body 1 tilts, and thus is beneficial to the normal use after the bottle body 1 tilts.

[0044] As an embodiment of the present invention, the discharging mechanism includes a first pulling tube 8, two pin columns 33, and two connecting plates 34. The first pulling tube 8 is fixedly communicated with the bottom of the first ring 5. The bottom end of the first pulling tube 8 is fixedly communicated with a hollow rod 9. A cylinder 10 is slidably sleeved on the lower end of the hollow rod 9. The lower end of the cylinder 10 is connected with a gravity adjusting mechanism. When the liquid level height inside the bottle body 1 gradually changes, the gravity adjusting mechanism is used to adjust so that the discharge end of the accumulated liquid is always below the liquid level. The lower end of the outer circle of the cylinder 10 is connected with a floating mechanism. The floating mechanism is used to drive the gravity adjusting mechanism to float in the upper space of the liquid inside the bottle body 1. The discharging mechanism is located below the floating mechanism. The two pin columns 33 are symmetrically fixed to the lower end of the outer circle of the first ring 5. The two connecting plates 34 are symmetrically fixed to the upper end of the outer circle of the hollow rod 9. The adjacent pin column 33 and the connecting plate 34 are rotatably connected. During operation, the accumulated liquid enters the inside of the first pulling tube 8 after passing through the first ring 5, then passes through the first pulling tube 8 and enters the hollow rod 9, then enters the cylinder 10 along the hollow rod 9, and finally is discharged into the inside of the bottle body 1 through the gravity adjusting mechanism. When the bottle body 1 is not tilted, the discharging mechanism remains vertical under the action of gravity and drops below the liquid level inside the bottle body 1. As the liquid level in the bottle body 1 rises, the floating mechanism also rises. The floating mechanism drives the cylinder 10 to slide upward along the hollow rod 9. At the same time, the cylinder 10 drives the gravity adjusting mechanism to move upward, so that the gravity adjusting mechanism is always below the liquid level and remains at the same depth. This is beneficial to preventing the gravity adjusting mechanism from being inserted too deep into the liquid level, increasing the resistance that needs to be overcome for drainage, and thus affecting the drainage effect. After the bottle body 1 is tilted due to external pulling, the gravity adjusting mechanism drops downward under the action of gravity, thereby pulling the lower part of the cylinder 10 to drop. At this time, the first pulling tube 8 is bent and deformed. The two connecting plates 34 rotate around the first ring 5. The two connecting plates 34 jointly drive the hollow rod 9 to rotate, so that when the first pulling tube 8 is bent, it will not be overly deformed due to the pulling of gravity and block the inside of the first pulling tube 8. After the bottle body 1 is tilted, the rotating mechanism drives the first ring 5 to adjust the angle, so that the hollow rod 9 can swing downward under the action of gravity and will not be blocked by the connecting plate 34, causing a fold angle between the cylinder 10 and the first ring 5, thereby adapting to the direction change after the bottle body 1 is flipped, so that the cylinder 10 and the gravity adjusting mechanism always drop downward under the action of gravity, so that the gravity adjusting mechanism can be located below the liquid level after dropping downward, which is beneficial to preventing air from entering the patient's chest cavity, and thus is beneficial to the normal use of the bottle body 1 after it is tilted.

[0045] As an implementation manner of the present invention, the floating mechanism includes a second ring 36, the second ring 36 is fixed to the lower end of the outer circle of the cylinder 10, and a plurality of floating balls 37 are fixedly connected to the outer wall circumference of the second ring 36 in an array; during operation, the provided floating balls 37 can provide buoyancy to float the cylinder 10, so that the cylinder 10 rises synchronously after the liquid level rises, and the cylinder 10 drives the gravity adjustment mechanism to rise, so that the gravity adjustment mechanism is always below the liquid level and always at the same depth below the liquid level, which is beneficial to preventing the insertion depth from being too deep and causing an increase in drainage resistance, resulting in difficult drainage.

[0046] As an implementation manner of the present invention, the gravity adjustment mechanism includes a second pull tube 38, the second pull tube 38 is fixed to the bottom of the cylinder 10, the second pull tube 38 is communicated with the inner circle of the cylinder 10, a discharge tube 39 is fixed to the lower end of the second pull tube 38, a gravity block 40 is fixed to the lower end of the discharge tube 39, and a plurality of discharge ports 41 are penetrated through the outer wall of the discharge tube 39; during operation, the accumulated liquid enters the second pull tube 38 from the cylinder 10 and then is discharged below the liquid level after passing through the discharge tube 39. After the bottle body 1 is tilted, the hollow rod 9 swings so that the discharge tube 39 can still be below the liquid level. When the liquid level rises above the plane where the first ring 5 is located, the cylinder 10 tilts upward under the action of the floating balls 37. Under the action of the gravity block 40, the discharge tube 39 is always in a vertical state, and the discharge tube 39 drives the second pull tube 38 to bend, so that the discharge tube 39 is inserted below the liquid level, which is beneficial to the normal use of the bottle body 1. Through the provided plurality of discharge ports 41, the accumulated liquid can be discharged laterally from the discharge ports 41 when the discharge tube 39 is in contact with the wall surface of the bottle body 1, which is beneficial to the normal use of the bottle body 1. At the same time, using a plurality of discharge ports 41 to discharge the accumulated liquid below the liquid level is beneficial to the stability of the liquid level, preventing the liquid level from shaking violently during drainage, which is beneficial to the discharge tube 39 always being below the liquid level and reducing the situation where the discharge tube 39 is separated from the liquid level due to the shaking of the liquid level.

[0047] As an embodiment of the present invention, brackets 42 are symmetrically fixed to the lower end of the outer ring of the cylinder 10. Through grooves 43 are formed through the opposite sides of the two brackets 42. Slide pins 44 are symmetrically fixed to the outer ring of the discharge pipe 39. The slide pins 44 are slidably connected to the through grooves 43. During operation, when the cylinder 10 tilts upward due to the bottle body 1 falling over and the liquid level being relatively high, the discharge pipe 39 drives the second pull pipe 38 to bend under the action of the gravity block 40. There is a situation where the second pull pipe 38 is blocked due to a large bending amplitude of the second pull pipe 38. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. Through the provided brackets 42, during the process of the discharge pipe 39 driving the second pull pipe 38 to bend, due to the action of gravity, the slide pins 44 on the outer ring of the discharge pipe 39 slide along the through grooves 43. After the slide pins 44 move to the side of the through grooves 43, the brackets 42 can provide a supporting effect on the discharge pipe 39. The gravity block 40 drives the discharge pipe 39 to be in a vertical state. The discharge pipe 39 rotates together with the slide pins 44, so that the bending arc of the second pull pipe 38 becomes smaller, which is beneficial to the second pull pipe 38 remaining unblocked during the bending process, and thus beneficial to the accumulated liquid passing through the bent second pull pipe 38.

[0048] As an embodiment of the present invention, a limit block 45 is fixed to the lower end of the outer ring of the hollow rod 9. The limit block 45 is slidably connected to the inner ring of the cylinder 10. A sliding seal ring 46 is fixed to the upper end of the inner ring of the cylinder 10. The sliding seal ring 46 is slidably connected to the outer ring of the hollow rod 9. During operation, through the provided limit block 45, the cylinder 10 can be limited when sliding on the outer ring of the hollow rod 9 to prevent the cylinder 10 from separating from the hollow rod 9. The provided sliding seal ring 46 can increase the sealing performance between the hollow rod 9 and the cylinder 10, which is beneficial to reducing the possibility of air entering the interior of the cylinder 10.

[0049] The working principle of the present invention:

[0050] When the patient turns over during a deep sleep, the water seal bottle may be easily pulled and may fall over. At the same time, if the medical staff is not present, the water seal bottle cannot be handled in time after it falls over. There is a situation where the drainage tube is separated from the liquid surface and connected to the air, and the liquid in the water seal bottle flows out of the bottle. The entry of air into the drainage tube may cause bacterial infection and may cause serious complications. The outflow of effusion will affect the doctor's test results of the effusion. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. First, the medical staff inserts the drainage tube through the connecting tube 3 into the interior of the first ring 5, and then the medical staff fixes the drainage tube through the clamping mechanism, which helps to prevent the drainage tube from being pulled out of the bottle body 1 when the bottle body 1 is pulled. During use, the patient's pleural effusion passes through the connecting tube 3 along the drainage tube under the action of gravity and the patient's breathing and enters the interior of the first ring 5, and then is discharged along the discharging mechanism to In the bottle body 1, when the bottle body 1 is not tipped over, the discharging mechanism maintains a vertical state under the action of gravity and falls below the liquid level inside the bottle body 1. After the bottle body 1 is tipped over due to external force, the provided tipping detection sensor 11 can sense the direction in which the bottle body 1 is tipped over, and then control the opening and closing mechanism to close the air outlet 6 located in the tipping direction to prevent the accumulated liquid from flowing out. The air outlet 6 away from the tipping direction is located at the top after the bottle body 1 is tipped over, and the rotation angle of the first ring 5 can be adjusted by the provided rotating mechanism, so that the discharging mechanism can swing along the tipping direction. After the bottle body 1 is tipped over, under the action of gravity, the bottle body 1 drives the discharging mechanism to rotate, so that the discharging mechanism can adjust its direction after rotation, and keep the discharging end below the liquid level inside the bottle body 1 under the action of gravity, which is beneficial to prevent air from entering the patient's chest cavity, so that the bottle body 1 can still be used normally after it is tipped over.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention to be protected, and the scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
