Description

Technical Field

[0001] This application relates to the field of thoracic drainage bottle technology, and more particularly to a closed thoracic drainage bottle. Background Technology

[0002] Closed chest drainage involves inserting one end of a drainage tube into the pleural cavity, while the other end is connected to a water-seal bottle positioned lower down. This allows for the drainage of air or collection of fluid from the pleural cavity, enabling the lung tissue to reopen and restore function. As a treatment method, it is widely used for the drainage of hemothorax, pneumothorax, and empyema, as well as post-thoracotomy procedures, playing a vital role in the treatment of these diseases.

[0003] The existing closed thoracic drainage bottle cannot monitor the amount of pleural fluid in the collection bottle, cannot make timely judgments when there is an active bleeding tendency, and cannot provide early warning when the pleural fluid in the collection bottle is about to be full. Moreover, if the drainage tube of the existing closed thoracic drainage bottle becomes blocked during the drainage process, it cannot be automatically cleared, and staff need to remove the tube and clear it, which increases the patient's suffering. Summary of the Invention

[0004] This application provides a closed thoracic drainage bottle, solving the technical problems of existing closed thoracic drainage bottles that cannot monitor the amount of pleural fluid in the collection bottle, cannot make timely judgments when active bleeding tendencies occur, and cannot provide early warnings when the collection bottle is about to be full. Furthermore, existing closed thoracic drainage bottles do not automatically clear blockages in the drainage tubing during drainage, requiring staff to remove the tubing and clear the blockage, increasing patient suffering. This application achieves the ability to monitor the amount of pleural fluid in the collection bottle, promptly determine active bleeding tendencies, provide early warnings when the collection bottle is about to be full, and automatically clear blockages in the drainage tubing during drainage without requiring tubing removal, thus reducing patient suffering.

[0005] Firstly, this application provides a closed thoracic drainage bottle, comprising a collection bottle, a water seal bottle, and a pressure measuring bottle. The collection bottle contains a liquid level alarm component and a fan component. A connecting tube is located at the top of the collection bottle, and a drainage component is installed inside the connecting tube. A flow meter is installed at the bottom end of the connecting tube extending into the collection bottle. The liquid level alarm component is suspended inside the collection bottle, and when the liquid level in the collection bottle rises to the point of contacting the liquid level alarm component, it can float the liquid level alarm component. The fan component is located directly below the bottom end of the connecting tube extending into the collection bottle. When the connecting tube... When liquid in the pipe enters the collection bottle, it can impact the rotation of the fan assembly. When the liquid in the collection bottle floats the liquid level alarm component and contacts the fan assembly, it can stop the fan assembly from rotating. The unblocking component includes a pressurizing part, a first on / off valve, a second on / off valve, a third on / off valve, and a side pipe. The first on / off valve and the second on / off valve are respectively located inside the top and bottom ends of the connecting pipe. The pressurizing part is located outside the top end of the connecting pipe, and the side pipe is located outside the bottom end of the connecting pipe. The third on / off valve is located inside the side pipe.

[0006] In conjunction with the first aspect, in one possible implementation, the liquid level alarm component includes a fixed plate, a sliding rod assembly, a float plate, a grid plate, and a first sensor; the fixed plate is fixedly connected to the inner side of the collection bottle; the sliding rod assembly passes through the fixed plate and is slidably connected to the fixed plate, with the top end of the sliding rod assembly overlapping the top surface of the fixed plate; the float plate is fixedly connected to the bottom end of the sliding rod assembly; the grid plate is located directly below the fan assembly and is fixedly connected to the side of the float plate; the first sensor is disposed on the top surface of the fixed plate.

[0007] In conjunction with the first aspect, in one possible implementation, the fan assembly includes a rotating shaft and a plurality of fan blades; the two ends of the rotating shaft are rotatably connected to the inner side of the collection bottle; the plurality of fan blades are located directly below the bottom end of the connecting tube and are arranged in a ring array on the outer side of the rotating shaft and fixedly connected to the rotating shaft; a second sensor is provided on the outer side of the rotating shaft.

[0008] In conjunction with the first aspect, in one possible implementation, the unblocking assembly further includes a side collection box; the side collection box is disposed outside the connecting pipe, and the side pipe extends into the side collection box.

[0009] In conjunction with the first aspect, in one possible implementation, the slide bar assembly includes a slide bar and a top plate; the slide bar passes through the fixed plate and is slidably connected to the fixed plate; the top plate is fixedly connected to the top end of the slide bar and can overlap the top surface of the fixed plate.

[0010] In conjunction with the first aspect, in one possible implementation, the closed thoracic drainage bottle provided in this application further includes a temperature sensor; the temperature sensor is disposed inside the collection bottle and is capable of detecting the temperature of the liquid inside the collection bottle.

[0011] In conjunction with the first aspect, in one possible implementation, the closed thoracic drainage bottle provided in this application further includes a controller; the first on / off valve, the second on / off valve, the third on / off valve, the pressurization unit, the first sensor, and the second sensor are respectively electrically connected to the controller.

[0012] Secondly, this application provides a method for using a closed thoracic drainage bottle, including:

[0013] Connect the bottom end of the connecting tube to the collection bottle and connect the top end of the connecting tube to the patient's chest cavity;

[0014] The controller controls the first and second opening and closing valves to open, and controls the third opening and closing valve to close, so that liquid can be drawn into the collection bottle through the connecting pipe.

[0015] The flow rate in the connecting tube per hour is monitored by the flow meter to promptly determine whether there is a tendency for active bleeding.

[0016] After the liquid leaves the connecting tube and enters the collection bottle, it impacts the fan assembly to rotate. The second sensor detects that the fan assembly is rotating normally, and at this time the connecting tube is in a normal drainage state.

[0017] When the liquid level in the collection bottle continues to rise until it touches the float plate, the float plate and the fence plate are lifted upwards. At the same time, the top of the slide rod assembly moves away from the first sensor. The first sensor sends a signal to the controller, and the controller issues a warning signal that the liquid level is about to be full, reminding the staff to replace the drainage bottle as soon as possible.

[0018] When the liquid level in the collection bottle continues to rise and the float plate and the fence plate continue to float upward until the fence plate contacts the fan assembly, the fan blades are locked at the fence plate and stop rotating. At this time, the second sensor detects that the fan assembly has stopped rotating and sends a signal to the controller. After receiving the signals sent by the first sensor and the second sensor, the controller issues a liquid level full alarm signal to remind the staff to replace the drainage bottle.

[0019] When the liquid level in the collection bottle does not reach the float plate and a blockage occurs in the connecting pipe, and liquid stops flowing from the bottom of the connecting pipe, the fan assembly will stop rotating. At this time, the second sensor sends a signal to the controller, which controls the first and second opening and closing valves to close, and simultaneously controls the third opening and closing valve to open. It also controls the pressurization unit to start, pressurizing the connecting pipe and conveying the foreign objects blocking the connecting pipe to the side pipe for discharge. Afterward, the controller controls the pressurization unit to stop working, controls the third opening and closing valve to close, and controls the first and second opening and closing valves to open, continuing normal drainage through the connecting pipe.

[0020] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0021] This application employs a collection bottle, a water seal bottle, and a pressure measuring bottle. The collection bottle is equipped with a liquid level alarm component and a fan component. A connecting pipe is installed at the top of the collection bottle, and a drainage component is installed inside the connecting pipe. A flow meter is installed at the bottom of the connecting pipe to monitor the drainage flow rate per hour, thereby enabling timely judgment of whether there is a tendency for active bleeding. The liquid level alarm component is suspended inside the collection bottle. When the liquid level in the collection bottle rises to the point of contacting the liquid level alarm component, it can float the liquid level alarm component, which can issue an early warning signal that the liquid level is about to be full.

[0022] The fan assembly is located directly below the bottom end of the connecting tube that extends into the collection bottle. When liquid in the connecting tube enters the collection bottle, it can impact the fan assembly to rotate. By observing the normal state of the fan assembly, it can be known that the connecting tube is in a normal drainage state and there is no blockage.

[0023] When the liquid in the collection bottle continues to float the liquid level alarm component and comes into contact with the fan component, it can stop the fan component from rotating. The liquid level alarm component sends out a liquid level warning signal and a fan component stop rotating signal, so that it knows that the liquid level in the collection bottle is full. At this time, the liquid level alarm component will send out a liquid level full alarm signal again to remind the staff to replace the drainage bottle, and at the same time reduce the possibility of causing active bleeding tendency.

[0024] The further configuration of the unblocking component includes a pressurizing unit, a first on / off valve, a second on / off valve, a third on / off valve, and a side pipe. The first and second on / off valves are respectively located inside the top and bottom ends of the connecting pipe. The pressurizing unit is located outside the top end of the connecting pipe, and the side pipe is located outside the bottom end of the connecting pipe. The third on / off valve is located inside the side pipe. When the liquid level alarm component fails to issue a near-full liquid level warning signal, and the connecting pipe becomes blocked, causing the fan component to stop rotating normally, the first and second on / off valves are closed, the third on / off valve is opened, and the pressurizing unit is activated. This continuously pressurizes the connecting pipe, causing foreign objects in the connecting pipe to be discharged through the side pipe, thus automatically unblocking the connecting pipe. After the connecting pipe is unblocked, the third on / off valve is closed, the pressurizing unit stops working, and the first and second on / off valves... This system allows for continued normal drainage; it effectively solves the technical problems of existing closed thoracic drainage bottles, which cannot monitor the amount of pleural fluid in the collection bottle, cannot promptly assess active bleeding tendencies, and cannot provide early warnings when the collection bottle is about to fill. Furthermore, existing closed thoracic drainage bottles do not automatically clear blockages in the drainage tubing during drainage, requiring staff to remove the tube and clear the blockage, increasing patient suffering. This system enables monitoring of the amount of pleural fluid in the collection bottle, timely assessment of active bleeding tendencies, early warnings when the collection bottle is about to fill, and automatic clearing of blockages in the drainage tubing during drainage, eliminating the need for tube removal and reducing patient suffering.

[0036] Reference Figure 1-3This application provides a closed thoracic drainage bottle, including a collection bottle 1, a water seal bottle 2, and a pressure measuring bottle 3. The collection bottle 1 is equipped with a liquid level alarm component 4 and a fan component 5. A connecting pipe 6 is located at the top of the collection bottle 1, and a drainage component 7 is installed inside the connecting pipe 6. A flow meter 13 is installed at the bottom end of the connecting pipe 6 extending into the collection bottle 1. The liquid level alarm component 4 is suspended inside the collection bottle 1, and when the liquid level in the collection bottle 1 rises to the point of contacting the liquid level alarm component 4, it can float the liquid level alarm component 4. The fan component 5 is located directly below the bottom end of the connecting pipe 6 extending into the collection bottle 1. When the liquid level in the connecting pipe 6... When the liquid enters the collection bottle 1, it can impact the fan assembly 5 to rotate. When the liquid in the collection bottle 1 floats the liquid level alarm component 4 and contacts the fan assembly 5, it can stop the fan assembly 5 from rotating. The unblocking component 7 includes a pressurizing part 71, a first on / off valve 72, a second on / off valve 73, a third on / off valve 74, and a side pipe 75. The first on / off valve 72 and the second on / off valve 73 are respectively located inside the top and bottom ends of the connecting pipe 6. The pressurizing part 71 is located outside the top end of the connecting pipe 6, and the side pipe 75 is located outside the bottom end of the connecting pipe 6. The third on / off valve 74 is located inside the side pipe 75.In this embodiment, the collection bottle 1, water seal bottle 2, and pressure measuring bottle 3 are all conventional instruments in the prior art. The collection bottle 1 and water seal bottle 2 are connected by a first pipe 9, and the water seal bottle 2 and pressure measuring bottle 3 are connected by a second pipe 10. The middle of the pressure measuring bottle 3 is connected to a third pipe 11 that is open to the atmosphere or connected to a suction device, and the top right side of the pressure measuring bottle 3 is connected to a fourth pipe 12 that is connected to a suction device. The above connections and functions are all in the prior art and will not be described in detail here. In normal use in this embodiment, the bottom end of the connecting tube 6 is connected to the collection bottle 1, and the top end of the connecting tube 6 is connected to the patient's chest cavity. By controlling the opening of the first opening and closing valve 72 and the second opening and closing valve 73, and controlling the closing of the third opening and closing valve 74, the fluid can be drained into the collection bottle 1 through the connecting tube 6. The flow meter 13 normally detects the drainage volume per hour in the connecting pipe 6. When the drainage volume per hour exceeds 200ml, it indicates a tendency for active bleeding in the patient's pleural cavity. The flow meter 13 will promptly issue an alarm to remind staff to treat the patient in a timely manner. During normal drainage, after the liquid enters the collection bottle 1, it impacts the rotation of the fan assembly 5. The normal rotation of the fan assembly 5 indicates that the drainage is in a normal state. When the liquid level in the collection bottle 1 continues to rise until it contacts the liquid level alarm assembly 4, the bottom of the liquid level alarm assembly 4 will float upwards. The upward floating of the bottom of the liquid level alarm assembly 4 indicates that the liquid level is about to reach the full level, and the liquid level alarm assembly 4 can issue an early warning that the liquid level is about to reach the full level. An alarm signal (which can be enhanced by adding a flashing light) reminds staff to replace the drainage bottle as soon as possible. When the liquid level in collection bottle 1 continues to rise and the bottom of the liquid level alarm component 4 continues to float upwards until the bottom of the liquid level alarm component 4 contacts the fan component 5, the fan component 5 is locked at the bottom of the liquid level alarm component 4 and stops rotating. At this time, the stopping state of the fan component 5 and the liquid level alarm component 4's earlier warning signal indicate that the liquid level in collection bottle 1 has reached the full state (maximum liquid level state). At this time, the liquid level alarm component 4 again issues a full liquid level alarm signal (which can be enhanced by adding a buzzer) to remind staff to replace the drainage bottle. When the liquid level in the collection bottle 1 continues to rise and the bottom of the liquid level alarm component 4 continues to float upwards until the bottom of the liquid level alarm component 4 contacts the fan component 5, the fan component 5 is locked at the bottom of the liquid level alarm component 4 and stops rotating. At this time, the liquid level in collection bottle 1 is fully charged (maximum liquid level state) and the liquid level alarm component 4 issues a full liquid level alarm signal (which can be enhanced by adding a buzzer) to remind staff to replace the drainage bottle. During normal use, if the liquid level in collection bottle 1 does not reach the liquid level alarm component 4, and a blockage occurs in connecting pipe 6, the fan assembly 5 will stop rotating when liquid stops flowing from the bottom of connecting pipe 6. At this time, the blockage in connecting pipe 6 can be determined simply by observing the state of the fan assembly 5 stopping. As the first and second opening and closing valves 72 and 73 are closed, and the third opening and closing valve 74 is opened, the pressurization unit 71 is activated to pressurize the connecting pipe 6, transporting the foreign object blocking the connecting pipe 6 to the side pipe 75 and discharging it. After the unblocking is completed, the pressurization unit 71 is stopped, the third opening and closing valve 74 is closed, and the first and second opening and closing valves 72 and 73 are opened to continue normal drainage through connecting pipe 6.

[0037] Reference Figure 1 , 4 -6. The liquid level alarm component 4 includes a fixed plate 41, a sliding rod assembly 42, a float plate 43, a fence plate 44, and a first sensor 45. The fixed plate 41 is fixedly connected to the inner side of the collection bottle 1. The sliding rod assembly 42 passes through the fixed plate 41 and is slidably connected to the fixed plate 41, with the top end of the sliding rod assembly 42 overlapping the top surface of the fixed plate 41. The float plate 43 is fixedly connected to the bottom end of the sliding rod assembly 42. The fence plate 44 is located directly below the fan assembly 5 and is fixedly connected to the side of the float plate 43. The first sensor 45 is located on the top surface of the fixed plate 41. The fan assembly 5 includes a rotating shaft 51 and multiple fan blades 52. The two ends of the rotating shaft 51 are rotatably connected to the inner side of the collection bottle 1. The multiple fan blades 52 are located directly below the bottom end of the connecting pipe 6 and are arranged in a ring array on the outer side of the rotating shaft 51 and fixedly connected to the rotating shaft 51. A second sensor 53 is provided on the outer side of the rotating shaft 51. In this embodiment, when the liquid level in the collection bottle 1 continues to rise, it first contacts the float plate 43 and the grid plate 44. The float plate 43 is lifted by buoyancy, which in turn lifts the grid plate 44. After the float plate 43 is lifted, the bottom end of the sliding rod assembly 42 no longer touches the top surface of the fixed plate 41; that is, the top end of the sliding rod assembly 42 leaves the first sensor 45. The first sensor 45 can no longer sense the top end of the sliding rod assembly 42, thus the first sensor 45 can send out a warning signal indicating that the liquid level is about to be full, reminding staff to replace the drainage bottle as soon as possible. When the liquid level in the collection bottle 1 continues to rise... The system continues to rise, and the float plate 43 and the fence plate 44 continue to float upwards until the fence plate 44 contacts the fan assembly 5. At this point, the fan blades 52 are engaged with the fence plate 44 and stop rotating. The second sensor 53 detects that the fan assembly 5 has stopped rotating. The signals detected by the first sensor 45 and the second sensor 53 can be used to determine that the liquid level in the collection bottle 1 has reached the full level (maximum liquid level). At this point, the liquid level alarm component 4 sends out a full liquid level alarm signal to remind the staff to replace the drainage bottle.

[0038] Reference Figure 1 The unblocking component 7 also includes a side collection box 76; the side collection box 76 is disposed on the outside of the connecting pipe 6, and the side pipe 75 extends into the side collection box 76. In this embodiment of the application, the side collection box 76 is further provided so that when unblocking the connecting pipe 6, foreign objects in the connecting pipe 6 can be discharged through the side pipe 75 into the side collection box 76 for collection, avoiding direct discharge of foreign objects to the outside and causing pollution.

[0039] Reference Figure 4-7The sliding rod assembly 42 includes a sliding rod 421 and a top plate 422. The sliding rod 421 passes through the fixed plate 41 and is slidably connected to the fixed plate 41. The top plate 422 is fixedly connected to the top end of the sliding rod 421 and can overlap the top surface of the fixed plate 41. In this embodiment, the sliding rod assembly 42 includes a sliding rod 421 and a top plate 422. The top plate 422 and the sliding rod 421 can suspend the float plate 43 and the fence plate 44 on the top surface of the fixed plate 41. When the liquid level in the collection bottle 1 does not touch the float plate 43, the top plate 422 is in contact with the fixed plate 41. The first sensor 45 senses the contact between the top plate 422 and the fixed plate 41. When the liquid level in the collection bottle 1 rises and the float plate 43 floats, the sliding rod 421 is also lifted, causing the top plate 422 to leave the fixed plate 41. At this time, the first sensor 45 cannot detect the top plate 422, thus issuing a warning signal that the liquid level is about to be full, reminding the staff to replace the drainage bottle as soon as possible.

[0040] Reference Figure 1-3 The closed thoracic drainage bottle provided in this application embodiment also includes a temperature sensor 8; the temperature sensor 8 is disposed inside the collection bottle 1 and can detect the temperature of the liquid inside the collection bottle 1. In this application embodiment, the temperature sensor 8 is further provided to detect the temperature of the liquid in the collection bottle 1, and when the temperature of the temperature sensor 8 is greater than 38°C, an abnormal temperature alarm is triggered by the temperature sensor 8 to alert staff that the patient has a tendency for active bleeding in the thoracic cavity.

[0041] Reference Figure 1-6 The closed thoracic drainage bottle provided in this application embodiment also includes a controller; the first on / off valve 72, the second on / off valve 73, the third on / off valve 74, the pressurizing unit 71, the first sensor 45, and the second sensor 53 are electrically connected to the controller. In this application embodiment, a PLC controller is further provided. The controller sends detection signals to the first sensor 45 and the second sensor 53, thereby controlling whether the first on / off valve 72, the second on / off valve 73, the third on / off valve 74, and the pressurizing unit 71 operate, and issuing commands for low-level warning and full-level alarm, facilitating automated drainage.

[0042] This application provides a method for using a closed thoracic drainage bottle, including:

[0043] Connect the bottom end of the connecting tube 6 to the collection bottle 1 and the top end of the connecting tube 6 to the patient's chest cavity. The controller opens the first and second opening / closing valves 72 and closes the third opening / closing valve 74, allowing fluid to drain into the collection bottle 1 through the connecting tube 6. The flow meter 13 monitors the drainage volume in the connecting tube 6 per hour to promptly determine if there is a tendency for active bleeding. After the fluid leaves the connecting tube 6 and enters the collection bottle 1, it impacts the rotation of the fan assembly 5. The second sensor 53 detects that the fan assembly 5 is rotating normally, indicating that the connecting tube 6 is in a normal drainage state. When the liquid level in the collection bottle 1 continues to rise until it contacts the float plate 43, the float plate 43 and the grid plate 44 are lifted upwards. Simultaneously, the top end of the sliding rod assembly 42 moves away from the first sensor 45, which sends a signal to the controller. The controller issues a warning signal indicating the liquid level is about to reach full, reminding staff to replace the drainage bottle as soon as possible. As the liquid level in the collection bottle 1 continues to rise, the float plate 43 and the grid plate 44 continue to rise until the grid plate 44... When the fan assembly 5 is contacted, the fan blade 52 is engaged with the fence plate 44 and stops rotating. At this time, the second sensor 53 detects that the fan assembly 5 has stopped rotating and sends a signal to the controller. After receiving the signals from the first sensor 45 and the second sensor 53, the controller issues a full liquid level alarm signal to remind the staff to replace the drainage bottle. When the liquid level in the collection bottle 1 does not contact the float plate 43 and a blockage occurs in the connecting pipe 6, the fan assembly 5 will stop rotating when liquid stops flowing from the bottom of the connecting pipe 6. At this time, the second sensor 53 sends a signal to the controller, which controls the first and second opening and closing valves 72 and 73 to close, and simultaneously controls the third opening and closing valve 74 to open. It also controls the pressurization unit 71 to start, pressurizing the connecting pipe 6 and conveying the foreign objects blocking the connecting pipe 6 to the side pipe 75 for discharge. After that, the controller controls the pressurization unit 71 to stop working, controls the third opening and closing valve 74 to close, and controls the first and second opening and closing valves 72 and 73 to open, continuing the normal drainage work through the connecting pipe 6.
