Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a chest cavity care anti-blockage drainage device. Background Technology

[0002] In clinical closed thoracic drainage, traditional thoracic drainage devices mainly consist of drainage tubes, drainage bottles, and auxiliary components, relying on gravity drainage to remove pleural effusion and pneumothorax. However, in actual nursing care, factors such as viscous drainage fluid, blood clot formation, and tissue debris blockage can easily lead to poor drainage or even complete blockage of the drainage tube. Currently, routine nursing care often relies on medical staff manually squeezing the drainage tube at regular intervals to clear the blockage through physical compression. However, this method not only increases the workload of medical staff but also makes it difficult to standardize the timing and force of the squeezing.

[0003] Although some improved devices employ a reciprocating mechanical squeezing structure, which can replace manual intermittent squeezing of the drainage tube and reduce nursing workload and the risk of tube blockage to some extent, these conventional squeezing structures still have significant limitations: they generally lack real-time monitoring and intelligent judgment functions for the drainage tube blockage status, and cannot automatically identify whether there is a blockage in the drainage tube; they can only perform squeezing at a fixed frequency according to a preset cycle. This results in the device being unable to initiate squeezing intervention in a timely manner at the initial stage of tube blockage, and also unable to determine the optimal squeezing time based on the actual drainage status, easily leading to problems such as over-squeezing, delayed squeezing, or ineffective squeezing. Summary of the Invention

[0004] To address the numerous shortcomings of existing chest drainage devices in terms of tube blockage prevention, intelligent monitoring, and automatic compression control, this paper proposes a chest care anti-blockage drainage device.

[0011] Furthermore, two positioning plates are fixedly installed on the pipe limiting groove, the extrusion assembly is located between the positioning plates, and a press switch is provided on the side wall of the positioning plate.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention utilizes the linkage between the buoyancy component of the water seal cavity and the laser photoelectric detection unit. By taking advantage of the fluctuation or stillness of the liquid surface in the water seal cavity when the drainage tube is unobstructed or blocked, the light-blocking plate is driven to form an intermittent or continuous optical path signal. The controller can determine whether the drainage tube is blocked in real time based on the signal characteristics. After the blockage signal is triggered, the controller can automatically send instructions to the adjustment component and the drive component to work, realizing the fully automated operation of the pipeline unblocking process without the need for medical staff to manually squeeze the drainage tube at regular intervals.

[0015] 2. This invention, through the adjustment component, simultaneously drives the squeezing roller to block the end of the drainage tube near the patient while squeezing the squeezing roller, cuts off the backflow path of gas and liquid, and prevents blood clots, tissue debris or drainage fluid in the tube from flowing back into the patient's chest cavity during the unblocking process, thus ensuring the safety of the unblocking operation from a physical structure perspective.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1-8As shown, the present invention discloses a chest cavity care anti-blockage drainage device, comprising a movable base 1, a column 2 on the movable base 1, a crossbeam 3 integrally formed on the top of the column 2, a drainage bottle 4 placed on the movable base 1, a pipe limiting groove 5 connecting the crossbeam 3 and the movable base 1, a squeezing component 6 slidably mounted on the pipe limiting groove 5, an adjusting component 7 at the bottom of the crossbeam 3, the squeezing component 6 abutting against the adjusting component 7, a driving component 8 on the column 2 connected to the squeezing component 6, a tube blockage detection unit 9 on the column 2 located on one side of the drainage bottle 4, and a controller (not shown in the figure) installed on the column 2, the tube blockage detection unit 9, the driving component 8, and the adjusting component 7 all electrically connected to the controller.

[0021] This invention achieves real-time monitoring of thoracic drainage tube 41 blockage and automated compression and unblocking operations through the electrical linkage and mechanical coordination of the blockage detection unit 9, adjustment component 7, drive component 8, and compression component 6. The pipe limiting groove 5 limits the drainage tube 41 and provides a sliding track for the compression component 6. The core working principle is as follows: the blockage detection unit 9 monitors the patency of the drainage tube 41 in real time and transmits the detection signal to the controller. The controller analyzes and judges the signal to determine whether the drainage tube 41 is blocked. If a blockage is determined, the controller immediately sends an action command to the adjustment component 7 and drive component 8. First, the adjustment component 7 adjusts the compression force of the compression component 6 to make the compression component 6 fit against the drainage tube 41. Then, the drive component 8 drives the compression component 6 to slide along the pipe limiting groove 5, and the compression component 6 physically squeezes the blocked drainage tube 41 to unblock the pipe.

[0022] like Figures 1-8 As shown, the drainage bottle 4 has an independent drainage chamber and a water seal chamber inside. The top of the drainage chamber has a bottle opening 1, and a screw cap 1 is screwed onto the bottle opening 1. The top of the water seal chamber has a bottle opening 2, and a screw cap 2 is screwed onto the bottle opening 2. The drainage tube 41 and the vent tube 42 are sealed through the screw cap 1. The water seal tube 43 and the exhaust tube 44 are sealed through the screw cap 2. The vent tube 42 and the water seal tube 43 are connected by a connecting tube 45. A buoyancy ball 46 is provided inside the water seal tube 43. A buoyancy rod 47 is slidably passed through the exhaust tube 44. A light-blocking plate 48 is fixed to the top of the buoyancy rod 47. The bottom of the buoyancy rod 47 is fixed to the buoyancy ball 46. The tube blockage detection unit 9 corresponds to the light-blocking plate 48. The bottom end of the water seal pipe 43 abuts against the bottom wall of the water seal cavity. A limiting groove 49 is provided on the water seal pipe 43. The limiting groove 49 extends to the opening at the bottom end of the water seal pipe 43. The buoyancy rod 47 slides through the limiting groove 49 and is fixedly connected to the buoyancy ball 46. There is a movable gap between the buoyancy rod 47 and the top wall of the limiting groove 49. The top end of the exhaust pipe 44 is threaded with a cap 3 410. A vent hole 411 is provided on the cap 3 410. A sliding hole for the buoyancy rod 47 to slide through is provided in the middle of the cap 3 410. The pipe blockage detection unit 9 includes a laser emitter 91 and a laser receiver 92. The laser emitter 91 and the laser receiver 92 are respectively installed on the front and rear sides of the column 2. The light-blocking plate 48 is located between the laser emitter 91 and the laser receiver 92. The light-blocking plate 48 has a light-transmitting hole 412. The light beam emitted by the laser emitter 91 passes through the light-transmitting hole 412 and is received by the laser receiver 92.

[0023] Working principle: The buoyancy ball 46 inside the water seal tube 43 is fixedly connected to the buoyancy rod 47 inside the exhaust pipe 44, and the buoyancy rod 47 passes through the limiting groove 49 of the water seal tube 43 and the sliding hole of the cap 410, achieving vertical sliding without jamming; when the drainage tube 41 is unobstructed, the patient's breathing causes the air pressure in the drainage chamber and the water seal chamber to fluctuate, and the liquid level in the water seal chamber fluctuates synchronously. The buoyancy ball 46 moves up and down with the liquid level, and the buoyancy rod 47 pulls the top light-blocking plate 48 to move up and down accordingly; when the drainage tube 41 is blocked, the air pressure fluctuation disappears, the liquid level is still, and the buoyancy ball 46, the buoyancy rod 47 and the light-blocking plate 48 are also fixed. The limiting groove 49 limits the sliding direction of the buoyancy rod 47 to prevent it from deviating and causing the light-blocking plate 48 to be misaligned, thus ensuring the accuracy of the detection.

[0024] The laser emitter 91 and laser receiver 92 of the tube blockage detection unit 9 are horizontally aligned, and the light-blocking plate 48 is located between the two optical paths and has a light-transmitting hole 412. The laser beam can pass through the light-transmitting hole 412 and be received by the receiver. When the drainage tube 41 is unobstructed, the light-blocking plate 48 moves up and down with the liquid surface, and the optical path is intermittently open and closed. The receiver transmits intermittent photoelectric signals to the controller. When the drainage tube 41 is blocked, the light-blocking plate 48 is stationary, and the optical path remains continuously open or closed. The receiver transmits continuous photoelectric signals to the controller, providing a direct basis for the controller to judge the tube blockage.

[0025] like Figures 1-8 As shown, the extrusion assembly 6 includes an n-shaped plate 61, which is slidably sleeved on the pipe limiting groove 5. An extrusion cylinder 62 is fixedly connected to the top of the n-shaped plate 61. A sliding block 63 is slidably adapted inside the extrusion cylinder 62. A sliding rod 64 is fixedly connected to the bottom of the sliding block 63. The sliding rod 64 slides through the top of the extrusion cylinder 62 and the top of the n-shaped plate 61. An extrusion wheel 65 is rotatably installed at the bottom end of the sliding rod 64. The extrusion wheel 65 is located inside the n-shaped plate 61 and extends into the pipe limiting groove 5. A sliding rod 66 is fixedly connected to the top of the sliding block 63. The sliding rod 66 slides through the top of the extrusion cylinder 62. An extrusion wheel 67 is rotatably installed at the top end of the sliding rod 66. A return spring 68 is slidably sleeved on the sliding rod 64. The return spring 68 abuts against the bottom wall of the sliding block 63 and the extrusion cylinder 62.

[0026] Working principle: The extrusion assembly 6 is based on the n-shaped plate 61, which is slidably fitted onto the pipe limiting groove 5, allowing the entire extrusion assembly 6 to slide smoothly along the extension direction of the limiting groove. This provides a motion basis for subsequent rolling extrusion and unblocking along the length of the drainage pipe 41. At the same time, the structure of the n-shaped plate 61 can protect and limit the extrusion components. The extrusion cylinder 62 is fixed to the top of the n-shaped plate 61, and the sliding block 63 inside is the core linkage component. Sliding rod 1 64 and sliding rod 2 66 are fixed to its upper and lower ends, respectively. The two sliding rods can slide vertically synchronously with the sliding block 63 inside the extrusion cylinder 62, thereby driving the extrusion roller 1 65 at the bottom and the extrusion roller 2 67 at the top to rise and fall synchronously. Extrusion roller 1 65 extends into the pipe limiting groove 5. The slot 5 contains the actuator that directly squeezes the drainage tube 41. Its rotating installation design converts the sliding friction of the squeezing component 6 along the limiting groove into rolling friction, which improves the smoothness of squeezing and clearing, and avoids damage to the wall of the drainage tube 41 by hard friction. The squeezing wheel 67 at the top is a force adjustment component. It does not act directly on the drainage tube 41, but abuts against the subsequent adjustment component 7. When the adjustment component 7 pushes the squeezing wheel 67 up and down, the squeezing wheel 65 can be moved up and down synchronously through the linkage of the sliding rod 66, the sliding block 63, and the sliding rod 64, thereby changing the downward pressure of the squeezing wheel 65 on the drainage tube 41 and realizing flexible adjustment of the squeezing force.

[0027] like Figures 1-8 As shown, the adjusting assembly 7 includes a fixed plate 71, a guide plate 72, and an electric push rod 73. The fixed plate 71 is fixed between the column 2 and the crossbeam 3. A linkage rod 74 slides through the middle of the fixed plate 71. The guide plate 72 is parallel to the moving direction of the extrusion assembly 6 and is fixed to one end of the linkage rod 74. The guide plate 72 is located between the pipe limiting groove 5 and the fixed plate 71. Both the guide plate 72 and the pipe limiting groove 5 are in an inclined state. The extrusion wheel 67 rolls in contact with the bottom of the guide plate 72. The other end of the linkage rod 74 is fixed to a guide plate 75 parallel to the guide plate 72. The electric push rod 73... Rod 73 is fixedly installed on one side of column 2. A movable frame 76 is fixedly installed on the output shaft of electric push rod 73. A pressing rod 77 is fixedly installed on one side of the bottom of movable frame 76. A pressing wheel 78 is rotatably installed at one end of pressing rod 77. The pressing wheel 78 rolls in contact with guide plate 75. A long slot 79 is opened on crossbeam 3 for movable frame 76 to slide through. After movable frame 76 passes through long slot 79, push frame 710 is fixedly connected. A horizontal rod 711 is fixedly installed at the end of push frame 710. A pressing roller 712 is fixedly connected at the end of horizontal rod 711. The pressing roller 712 extends into pipe limiting groove 5.

[0028] Working principle: When the electric push rod 73 drives the adjustment component to operate, the squeezing roller 65 squeezes the drainage tube 41. At the same time, the moving frame 76 simultaneously drives the push frame 710 and the horizontal rod 711 to extend the squeezing roller 712 into the pipe limiting groove 5, forming a tight seal on the upper part of the drainage tube 41. This structural design ensures that when the squeezing roller 65 rolls along the drainage tube 41 towards the drainage bottle 4 to clear the blockage, the upper part of the drainage tube 41 near the patient is always blocked by the squeezing roller 712. This physically cuts off the backflow path of gas and liquid, preventing blockages or drainage fluid from flowing back into the patient's chest cavity during the clearing process, thus improving the safety of the clearing operation.

[0029] like Figures 1-8 As shown, two positioning plates 713 are also fixedly installed on the pipe limiting groove 5. The extrusion assembly 6 is located between the positioning plates 713. A push switch (not shown in the figure) is provided on the side wall of the positioning plate 713. When the n-shaped plate 61 moves to contact the push switch, the push switch is triggered. A limiting rod 714 is fixedly connected to the guide plate 72. The limiting rod 714 slides through the fixed plate 71.

[0030] The two positioning plates 713 on the pipe limiting groove 5 form the sliding range of the extrusion assembly 6. The n-shaped plate 61 of the extrusion assembly 6 is limited to move between the two plates, which prevents the n-shaped plate 61 from sliding out of the pipe limiting groove 5 from the physical structure. The push switch on the side wall of the positioning plate 713 is an electrically controlled trigger and is electrically connected to the controller. When the n-shaped plate 61 slides with the drive assembly 8 to contact the push switch, the push switch immediately sends an electrical signal to the controller. After receiving the signal, the controller accurately controls the start and stop of the servo motor 81 and the electric push rod 73, realizing the automatic triggering of the decompression and reset action after the extrusion and unblocking is in place, as well as the automatic start of the whole machine after the extrusion assembly 6 is reset in place. No manual intervention is required, ensuring the automated closed loop of the extrusion and unblocking process.

[0031] like Figures 1-8 As shown, the drive assembly 8 includes a servo motor 81, a pull rope 1 82, a pull rope 2 83, a rope reel 1 84, and a rope reel 2 85. The servo motor 81 is fixedly mounted on the side wall of the column 2. The output end of the servo motor 81 is connected to a drive shaft 86. Both the rope reel 1 84 and the rope reel 2 85 are rotatably mounted on the side wall of the column 2. The drive shaft 86 drives the rope reel 1 84 and the rope reel 2 85 to rotate synchronously through a bevel gear set 87. A through slot 88 is provided at the end of the crossbeam 3. A guide rope wheel 89 is rotatably installed inside. One end of the pull rope 82 is wound around the wind rope wheel 84, and the other end of the pull rope 82 passes around the guide rope wheel 89 and is fixed to the n-shaped plate 61. One end of the pull rope 83 is wound around the wind rope wheel 85, and the other end of the pull rope 83 moves through the column 2 and the positioning plate 713 and is fixed to the n-shaped plate 61. A guide rope wheel 810 is rotatably installed on the side wall of the positioning plate 713 facing away from the n-shaped plate 61, and the pull rope 83 passes around the guide rope wheel 810.

[0032] Working principle: After the servo motor 81 starts, the output end drives the transmission shaft 86 to rotate. The transmission shaft 86 transmits power synchronously to the first rope winding wheel 84 and the second rope winding wheel 85 on the column 2 through the bevel gear set 87, realizing the synchronous rotation of the two rope winding wheels and providing synchronous power for the winding and unwinding of the rope. The bevel gear set 87 consists of two meshing bevel gears. One bevel gear is linked to the central shaft of the first rope winding wheel 84 and the second rope winding wheel 85, and the other bevel gear is fixedly connected to the transmission shaft 86. Rope winding and tension transmission: When the first and second rope winding wheels rotate synchronously, the first rope 82 and the second rope 83 are wound and unwound in opposite directions (one winding and one unwinding): When unblocking, the first rope winding wheel 84 releases the first rope 82 and the second rope winding wheel 85 winds up the second rope 83, providing downward tension to the extrusion assembly 6; when resetting, the first rope winding wheel 84 winds up the first rope 82 and the second rope winding wheel 85 releases the second rope 83, providing upward tension to the extrusion assembly 6; the servo motor 81 can realize forward and reverse rotation and speed adjustment. With the instructions of the controller, it can accurately control the sliding direction (unblocking / resetting) of the extrusion assembly 6 and adjust the sliding speed.

[0033] In practical use, medical staff move the device to the patient's bedside using the casters, and step on the brake to fix the moving seat 1; connect one end of the drainage tube 41 to the patient's chest drainage interface, and pass the other end through the tube limiting groove 5 and into the drainage cavity of the drainage bottle 4 to complete the connection of the drainage tube 41; add sterile saline to the water seal cavity of the drainage bottle 4 so that the bottom end of the water seal tube 43 is immersed in the saline to form a water seal layer, and the limiting groove 49 is below the water seal layer throughout the entire process; The controller activates the laser emitter 91 to emit a laser. When the drainage tube 41 is unobstructed, the water seal layer fluctuates with the patient's breathing, causing the buoyancy ball 46 and buoyancy rod 47 to fluctuate, which in turn causes the light-blocking plate 48 to fluctuate, allowing the laser receiver 92 to intermittently receive the laser emitted by the laser emitter 91. When the drainage tube 41 is blocked, the water seal layer does not fluctuate. In this case, the laser receiver 92 either passes through the light-transmitting hole 412 on the light-blocking plate 48 continuously or is blocked. At this time, the laser receiver 92 transmits a light path blocking signal or a light path opening signal to the signal processing module of the controller. The signal processing module starts timing. When the timing exceeds the predetermined time, the electric push rod 73 is triggered to extend, driving the moving frame 76 and the pushing frame 710 to move, causing the squeezing roller 712 and squeezing wheel 65 to press the drainage tube 41. Then, the controller controls the servo motor 81 to work. 1. Drive the first rope reel 84 and the second rope reel 85 to rotate, causing the first rope reel 84 to release the first rope 82 and the second rope reel 85 to reel in the second rope 83. This allows the n-shaped plate 61 to slide downward along the pipe limiting groove 5, thereby driving the first extrusion roller 65 to roll and extrude the drainage pipe 41, squeezing the gas and liquid in the drainage pipe 41 towards the drainage bottle 4, thus clearing the drainage pipe 41. When the n-shaped plate 61 touches the lower push switch, the controller controls the servo motor 81 to pause, and the electric push rod 73 retracts, causing the extrusion roller 712 and the first extrusion roller 65 to separate from the drainage pipe 41. At this time, the drainage pipe 41 remains unobstructed.
