Description

Technical Field

[0001] The present invention relates to the technical field of drainage tubes, and more particularly to a drainage tube for thoracic surgery with fixing and squeezing functions. Background Art

[0002] After thoracic surgery, it is often necessary to use a drainage tube to drain the pleural effusion, which can effectively reduce the pressure in the thoracic cavity, reduce the pressure on the lung tissue, and relieve symptoms such as difficulty breathing.

[0003] Chinese patent application number CN207605172U discloses a drainage tube for thoracic surgery equipped with a fixing and squeezing device, specifically relating to the field of drainage tubes. The drainage tube is provided with a positioning block at the drainage tube head position of the tube body, and several fixing devices are assembled on the bracket, and the tail end is connected to the effusion bottle; a rotating drum with a squeezing block is sleeved in the bulged tube body, and the motor connected to the rotating drum is provided with a fixing frame, wherein the fixing devices are distributed at intervals on the bracket, and each fixing device is provided with a suction cup at the bottom and an operating handle at the top.

[0004] This technical solution can fix the drainage tube outside the human body through a fixing device. During drainage, the motor drives the rotating drum to make the squeezing block squeeze the accumulated fluid in the tube into the fluid bottle, thereby promoting the smooth discharge of the accumulated fluid. However, in actual use, there is not only fluid but also gas in the chest cavity. The fluid bottle is usually in a negative pressure state, and the fluid is discharged by relying on the pressure difference between the negative pressure environment and the chest cavity. However, as the accumulated fluid is continuously squeezed into the fluid bottle, the gas will also enter synchronously, causing the pressure in the fluid bottle to gradually increase, the negative pressure environment to be destroyed, and the drainage tube to lose the negative pressure guidance. , the suction force on the accumulated fluid is reduced, resulting in poor drainage. In addition, although the continuous rotation of the rotating drum and the squeezing block in the scheme can increase the discharge volume of the accumulated fluid, it will cause the drainage tube to shift and become loose, requiring repeated winding; and the movement of the drainage tube may pull the suction cup assembly adsorbed on the human skin. Since the suction cup is close to the skin near the wound, it is easy to cause pain when pulled, and even cause the wound to rupture. Therefore, its practical effect is poor. For this reason, the present invention proposes a thoracic surgery drainage tube with fixing and squeezing functions, aiming to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a thoracic surgical drainage tube with fixing and squeezing functions to solve the problems raised in the above background technology: In order to achieve the above object, the present invention provides the following technical solutions: A thoracic surgical drainage tube with fixing and squeezing functions comprises a drainage tube, wherein the lower end of the drainage tube is fixedly connected to a fluid collection bottle, the fluid collection bottle is fixedly connected to a fixing frame, the fixing frame is fixedly connected to an squeezing frame, a rotating rod is rotatably mounted on the squeezing frame, an extrusion head is fixedly connected to an outer position of the rotating rod, a positioning pulley is movably connected inside the squeezing frame, and a movable pulley is movably connected to the side of the positioning pulley on the squeezing frame, the drainage tube passes through the movable pulley and the positioning pulley in sequence, and enters the squeezing frame to be squeezed by the squeezing head; One end of the rotating rod is fixedly connected to a No. 1 gear, the No. 1 gear is movably connected to the No. 2 gear, the No. 2 gear is fixedly connected to a screw rod, the screw rod is movably mounted on the exhaust bottle, a piston head is movably mounted on the screw rod, and the exhaust bottle is connected to the effusion bottle through an air intake pipe; One end of the air suction pipe is fixedly connected to a filter bin, a movable plate is movably installed in the filter bin, a brush bundle is fixedly connected to the movable plate, and a filter hole is opened on the filter bin at a position corresponding to the brush bundle.

[0006] By adopting the above technical solution, the extrusion head rotates continuously, squeezing the drainage tube to generate negative pressure in the drainage tube, making the drainage smoother. When the extrusion head rotates, the drainage tube drives the movable pulley to move upward, thereby avoiding the position where the drainage tube contacts the wound and reducing the impact on the wound. The exhaust bottle absorbs the gas in the effusion bottle and discharges the gas to maintain the negative pressure environment in the effusion bottle. A filter bin is provided at one end of the intake pipe, and the intake air is filtered through the filter bin, making the intake smooth and not easy to be blocked.

[0007] Preferably, a mounting groove is provided on the fixing frame, a fixing bolt is threadedly connected to the fixing frame, one end of the fixing bolt is fixedly connected to a fixing plate, and the fixing plate is located in the mounting groove.

[0012] By adopting the above technical solution, the movable pulley moves downward by gravity, pulling the drainage tube downward, thereby reserving part of the length. When the extrusion head rotates to pull the drainage tube, it moves upward through the movable pulley, avoiding the position where the drainage tube contacts the wound from moving.

[0013] Preferably, a rubber sleeve is movably connected in the extrusion frame, and both ends of the rubber sleeve pass through the extrusion frame and are fixedly connected to a limiting head, and the drainage tube is fixedly connected in the rubber sleeve.

[0014] By adopting the above technical solution, the rubber sleeve wraps the drainage tube through deformation, thereby fixing the connection.

[0015] Preferably, the fluid collection bottle is fixedly connected with a connecting port, the connecting port is fixedly connected with a threaded platform, the fixing frame is fixedly connected with a sealing frame, the fixing frame is fixedly connected with a No. 1 sealing ring at a side position of the sealing frame, the connecting port and the threaded platform are located on the fixing frame, and the threaded platform is located at a side position of the No. 1 sealing ring, a sealing cover is movably installed on the fixing frame, the sealing cover is threadedly connected to the threaded platform, and the sealing frame and the No. 1 sealing ring are located on the inner side of the sealing cover.

[0018] By adopting the above technical solution, the eccentric block and the center of the exhaust bottle are misaligned with each other, so that when the screw rod rotates, the eccentric block is restricted and cannot rotate synchronously, thereby moving up and down.

[0019] Preferably, a discharge pipe is fixedly connected to the bottom of the exhaust bottle, a one-way exhaust valve is fixedly connected to the discharge pipe, a rubber stopper is fixedly connected to the fixed frame, one end of the intake pipe and the drainage pipe passes through the rubber stopper and enters the fluid accumulation bottle, and a one-way air inlet valve is fixedly connected to the intake pipe.

[0020] By adopting the above technical solution, when the piston head moves downward, the gas in the liquid accumulation bottle can be easily discharged through the discharge pipe.

[0023] Preferably, the filter bin and the air intake pipe are in communication with each other, a spring is provided on the filter bin at an inner side of the movable plate, and the air intake pipe is in communication with the filter bin through the air guide pipe.

[0024] By adopting the above technical solution, when the movable plate moves to a side position of the air guide tube, the air guide tube can easily absorb the gas on the side of the movable plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1) When the drainage tube is in use, the stepper motor rotates forward and reverse, causing the extrusion head to squeeze the drainage tube downward or upward. Squeezing the drainage tube increases the flow rate of the drainage tube, making drainage smoother. The extrusion head squeezes the drainage tube downward, pulling the drainage tube downward. By reserving sufficient length at the movable pulley, the movable pulley moves upward, thereby preventing the upper end of the drainage tube from moving relative to the wound. Then, the extrusion head rotates in the opposite direction, pushing the drainage tube upward, eliminating the influence of the previous downward movement, and making the connection position between the drainage tube and the wound more fixed; 2) When the drainage tube is in use, the rotating rod rotates the screw rod through the No. 1 and No. 2 gears. The screw rod rotates forward to raise the piston head, thereby sucking air into the effusion bottle. The screw rod rotates backward to lower the piston head, thereby expelling the inhaled gas. This maintains the negative pressure environment in the effusion bottle, allowing the effusion bottle to maintain smooth drainage of the drainage tube through the good internal negative pressure environment. 3) The suction pipe absorbs the gas in the effusion bottle and filters the gas through the filter chamber to prevent impurities from entering the suction pipe and causing pipe blockage. When the suction pipe stops sucking air, the movable plate resets and the brush bundle is inserted into the filter hole in the opposite direction, thereby dredging the filter hole and making the filter chamber less likely to be blocked.

The movable pulley 21 can move up and down, thereby reserving part of the drainage tube 1. When the lower position of the drainage tube 1 is pulled, it is convenient to move upward through the movable pulley 21, thereby avoiding pulling the contact position between the drainage tube 1 and the wound. The drainage tube 1 passes through the movable pulley 21 and the positioning pulley 19 in turn, and enters the extrusion frame 12 to be squeezed against the extrusion head 15.

[0029] A mounting groove 4 is provided on the fixing frame 3, and a fixing bolt 5 is threadedly connected to the fixing frame 3. One end of the fixing bolt 5 is fixedly connected to a fixing plate 6 for increasing the contact area and improving the stability of the installation. The fixing plate 6 is located in the mounting groove 4, so that the fixing frame 3 can be easily clamped on the side of the bed.

[0030] The rotating rod 13 is rotatably connected to the extrusion frame 12 through the No. 1 bearing 16. A stepper motor 17 is fixedly connected to one side of the extrusion frame 12. The stepper motor 17 rotates forward and then reverses, rotating forward and reverse regularly. The stepper motor 17 is fixedly connected to the other end of the rotating rod 13, and the rotating rod 13 is fixedly connected to the extrusion head 15 through the connecting rod 14.

[0031] A No. 1 support rod 18 is fixedly connected to the extrusion frame 12, and a positioning pulley 19 is rotatably connected to the No. 1 support rod 18. The No. 1 support rod 18 supports the positioning pulley 19. A slide groove 23 is provided on the extrusion frame 12, and a No. 2 support rod 20 is movably installed in the slide groove 23. The movable pulley 21 is rotatably connected to the No. 2 support rod 20. The No. 2 support rod 20 moves up and down in the slide groove 23, thereby driving the movable pulley 21 to move synchronously. Limiting plates 22 are fixedly connected to both ends of the No. 2 support rod 20.

[0032] A rubber sleeve 24 is movably connected inside the extrusion frame 12, and both ends of the rubber sleeve 24 pass through the extrusion frame 12 and are fixedly connected with limiting heads 25. The limiting heads 25 prevent the rubber sleeve 24 from detaching from the extrusion frame 12. The drainage tube 1 is fixedly connected inside the rubber sleeve 24. The rubber sleeve 24 is appropriately enlarged by elasticity so that it can be installed on the drainage tube 1.

[0033] The use steps of the present invention are as follows: the upper end of the drainage tube 1 is fixedly connected to the wound position, the drainage tube 1 passes downward through the rubber sleeve 24, the movable pulley 21, and the positioning pulley 19, and then enters the extrusion frame 12, passes downward through the fixed frame 3 and the rubber stopper 39 into the effusion bottle 2, so that the effusion in the pleural cavity is introduced into the effusion bottle 2, and the No. 2 support rod 20 in the movable pulley 21 moves to the lowest position of the slide groove 23. When the stepping motor 17 rotates forward, the rotating rod 13 and the extrusion head 15 rotate synchronously, so that the extrusion head 15 rotates downward and squeezes the drainage tube 1 inside the extrusion frame 12. When the drainage tube 1 is squeezed downward, it pushes the drainage tube 1 downward, so that the movable pulley 21 moves upward, and the No. 2 support rod 20 moves upward synchronously, so that the contact position between the upper end of the drainage tube 1 and the wound will not move, causing problems with the wound; After the stepper motor 17 finishes forward rotation, it reverses, causing the rotating rod 13 and the extrusion head 15 to rotate upward, thereby pushing the drainage tube 1 upward, causing the drainage tube 1 to move upward, thereby eliminating the impact caused by the downward movement of the drainage tube 1 during the previous forward rotation. The extrusion head 15 squeezes the drainage tube 1, making the liquid flow in the drainage tube 1 smoother and less prone to blockage. The extrusion head 15, movable pulley 21 and other structures make it difficult for the upper end of the drainage tube 1 to move in contact with the wound, thereby improving the fixing effect.

[0034] For example 2, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , combined with the basis of Example 1, the difference is that one end of the rotating rod 13 is fixedly connected to the No. 1 gear 26, the No. 1 gear 26 is movably connected to the No. 2 gear 27, and the No. 2 gear 27 is fixedly connected to the screw rod 29, so that the rotating rod 13 drives the screw rod 29 to rotate, and the screw rod 29 is movably installed on the exhaust bottle 28. The screw rod 29 rotates synchronously with the forward and reverse rotation of the rotating rod 13. A piston head 32 is movably installed on the screw rod 29, so that the piston head 32 is easy to rise and fall. The exhaust bottle 28 is connected to the effusion bottle 2 through the intake pipe 35, so that the exhaust bottle 28 absorbs the gas in the effusion bottle 2 through the intake pipe 35 to maintain a negative pressure environment.

[0035] A connecting port 7 is fixedly connected to the fluid effusion bottle 2, a threaded platform 8 is fixedly connected to the connecting port 7, a sealing frame 9 is fixedly connected to the fixing frame 3, a sealing ring 10 is fixedly connected to the fixing frame 3 at a side position of the sealing frame 9, and the sealing frame 9 supports the sealing ring 10. The connecting port 7 and the threaded platform 8 are located on the fixing frame 3, and the threaded platform 8 is located at a side position of the sealing ring 10. A sealing cover 11 is movably installed on the fixing frame 3, and the sealing cover 11 is threadedly connected to the threaded platform 8, so that the sealing cover 11 and the threaded platform 8 can be installed and disassembled, making it easy to install and disassemble the fluid effusion bottle 2, and the sealing frame 9 and the No. 1 sealing ring 10 are located on the inner side of the sealing cover 11.

[0036] The exhaust bottle 28 is fixedly connected to the fixed frame 3, and the screw rod 29 is rotatably connected to the exhaust bottle 28 through the No. 2 bearing 30. An eccentric block 31 is threadedly connected to the screw rod 29, and the eccentric block 31 is slidingly connected to the inner wall of the exhaust bottle 28 through the piston head 32. The piston head 32 is fixedly connected to the eccentric block 31, so that the eccentric block 31 can easily drive the piston head 32 to move up and down.

[0037] A discharge pipe 33 is fixedly connected to the bottom of the exhaust bottle 28, and a one-way exhaust valve 34 is fixedly connected to the discharge pipe 33. The gas in the exhaust bottle 28 can be easily discharged through the discharge pipe 33 and the one-way exhaust valve 34. A rubber plug 39 is fixedly connected to the fixed frame 3. One end of the intake pipe 35 and the drainage tube 1 pass through the rubber plug 39 and enter the fluid accumulation bottle 2. The rubber plug 39 seals the connection port 7. A one-way air intake valve 36 is fixedly connected to the intake pipe 35, so that the exhaust bottle 28 can easily absorb the gas in the fluid accumulation bottle 2 through the one-way air intake valve 36.

[0038] The use steps of the present invention are as follows: when the rotating rod 13 rotates, the screw rod 29 is driven to rotate through the No. 1 gear 26 and the No. 2 gear 27. When the rotating rod 13 rotates, the screw rod 29 drives the eccentric block 31 and the piston head 32 to move upward, so that the piston head 32 moves upward in the exhaust bottle 28, so that the exhaust bottle 28 absorbs the gas in the effusion bottle 2 through the suction pipe 35. The one-way air inlet valve 36 makes it easy to inhale the air through the suction pipe 35, so that the gas cannot flow into the effusion bottle 2 in the reverse direction. When the piston head 32 moves upward to the uppermost position of the exhaust bottle 28, the rotating rod When 13 rotates in the opposite direction, the screw rod 29 drives the eccentric block 31 and the piston head 32 to move downward, thereby pushing the gas sucked into the exhaust bottle 28 downward, and discharging it through the exhaust pipe 33 and the one-way exhaust valve 34, thereby discharging the gas in the effusion bottle 2. When the drainage tube 1 is draining, the gas will be discharged. These gases will enter the effusion bottle 2 and destroy the internal negative pressure environment. The gas in the effusion bottle 2 is absorbed by the exhaust bottle 28 and other structures, thereby maintaining the negative pressure environment, so that the lower end of the drainage tube 1 is well absorbed by the negative pressure, thereby improving the smoothness of the drainage tube 1 drainage.

[0039] For example three, please refer to Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 and Figure 9 , combined with the basis of Example 2, the difference is that one end of the suction pipe 35 is fixedly connected to the filter bin 37, and a movable plate 40 is movably installed in the filter bin 37. The movable plate 40 moves left and right in the filter bin 37, and a brush bundle 45 is fixedly connected to the movable plate 40. The filter bin 37 is provided with a filter hole 43 at a position corresponding to the brush bundle 45, so as to dredge the filter hole 43.

[0040] A No. 2 sealing ring 41 is fixedly connected to the edge of the movable plate 40, and the No. 2 sealing ring 41 slides on the inner wall of the filter bin 37. Through good air tightness, the suction pipe 35 can easily absorb the movable plate 40 to move. A movable rod 44 is fixedly connected to the movable plate 40, and the movable rod 44 is slidably connected to the filter bin 37. The movable rod 44 enables the movable plate 40 to move in a straight line, so that the brush bundle 45 can be easily aligned with the filter hole 43 for dredging.

[0041] The filter bin 37 and the air intake pipe 35 are connected to each other. A spring 42 is provided on the filter bin 37 at the inner side of the movable plate 40. The spring 42 pushes the movable plate 40 to reset. The air intake pipe 35 is connected to the filter bin 37 through the air guide pipe 38, so that the air intake pipe 35 enters the filter bin 37 through the air guide pipe 38 to absorb gas.

[0042] The use steps of the present invention are as follows: when the suction pipe 35 is sucking air, the gas in the suction pipe 35 is extracted, so that the filter chamber 37 generates negative pressure, so that the movable plate 40, the brush bundle 45 and the movable rod 44 move inward, and the brush bundle 45 moves out of the filter hole 43. The movement of the movable plate 40 causes the spring 42 to compress. When the movable plate 40 moves to the side position of the suction port at one end of the air guide pipe 38, the filter chamber 37 and the suction pipe 35 are connected through the air guide pipe 38. The diameter of the air guide pipe 38 is much smaller than that of the suction pipe 35, so that when the movable plate 40 moves to the side position of the suction port at one end of the air guide pipe 38, the suction pipe 35 still contains a large suction force, which is convenient for fixing the movable plate 40 and maintaining the compression state of the spring 42. At this time, the gas in the filter bin 37 is introduced into the intake pipe 35 through the air guide pipe 38, and the filter bin 37 absorbs the gas in the effusion bottle 2 through the filter hole 43. When the exhaust bottle 28 is exhausted through the exhaust pipe 33, the suction force of the intake pipe 35 disappears, the spring 42 resets, and the movable plate 40 is reset, so that the brush bundle 45 is inserted into the filter hole 43, thereby clearing it and avoiding blockage during inhalation. At the same time, the movable plate 40 is reset and moved to the other side of the air guide pipe 38, so as to seal the filter bin 37 again.
