Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a bedside drainage device for hepatobiliary surgery. Background Art

[0002] In the clinical treatment process of hepatobiliary surgery, drainage operation is an extremely important and common treatment method. For example, after operations such as partial hepatectomy and cholecystectomy, metabolic products such as residual fluid and blood often remain in the patient's body. If they cannot be discharged in a timely and effective manner, it is extremely easy to cause complications such as infection and tissue adhesion, seriously affecting the patient's recovery process and prognosis. Therefore, a reliable bedside drainage device plays a crucial role in the patient's recovery.

[0003] However, there are many problems with the bedside drainage devices widely used in the market at present. In terms of movement and positioning, most traditional drainage devices adopt a fixed base or a simple universal wheel design. The devices with a fixed base are difficult to move flexibly. When the patient needs to transfer beds or the ward layout is adjusted, medical staff need to spend a lot of energy moving the device, which not only increases the work burden but also may cause the drainage tube to shift or even fall off due to shaking during the handling process; while for some devices equipped with universal wheels, their braking structure is not stable, and during daily nursing operations such as turning the patient over and changing the bedsheet, the device is prone to accidental sliding, seriously affecting the stability and safety of drainage.

[0004] Low device integration is also a major defect of existing drainage devices. Traditional devices usually set the flushing system, drainage collection system, control and monitoring system, etc. separately, and the components are connected by complex pipelines. This design not only occupies a large amount of ward space, making the ward environment appear crowded and messy, but also greatly increases the operation difficulty and error probability of medical staff. For example, when dealing with the blockage of the drainage tube emergently, medical staff need to switch operations between multiple scattered components, which not only wastes the treatment time but also may cause the patient's condition to deteriorate due to untimely operation.

[0005] Drainage tube blockage is a problem that has long troubled clinical treatment. The drainage fluid in hepatobiliary surgery often contains substances such as tissue fragments, blood clots, and bile crystals. During the drainage process, these substances are extremely easy to adhere to the inner wall of the drainage tube and gradually form blockages. Once the drainage tube is blocked, not only the expected drainage effect cannot be achieved, but also the pressure in the patient's body may increase, causing serious consequences such as pain and infection. At present, manual flushing or replacing the drainage tube is commonly used clinically to solve the problem, but the manual flushing operation is cumbersome and the flushing effect is difficult to guarantee; frequent replacement of the drainage tube will increase the patient's pain and infection risk, and at the same time also increases the medical cost.

[0006] In the observation and treatment of the drainage fluid, the existing devices are seriously lacking in intelligence. Medical staff need to frequently observe indicators such as the volume, color, and properties of the fluid in the drainage bag at close range, which not only consumes a large amount of time and energy but also poses a risk of missing changes in the patient's condition due to untimely observation. In addition, when the traditional drainage device drains the fluid, medical staff usually need to manually pour the fluid in the drainage bag into a designated container, and it is extremely easy for the fluid to leak during this process, polluting the ward environment and further increasing the risk of nosocomial infection. Therefore, it is of great significance to develop a bedside drainage device for hepatobiliary surgery with flexible mobile positioning, high integration, intelligent anti-blocking, and treatment functions to improve the clinical treatment level and the patient's rehabilitation experience. Summary of the Invention

The positioning electric push rod, the flushing pump, the device power supply, the camera, and the outward pushing electric push rod are respectively electrically connected to the intelligent control component.

[0013] A further solution of the present invention is that the display touch screen is connected with a hanging buckle plate, and the screen power supply and the screen wireless communication module are both positioned and connected with the hanging buckle plate.

[0014] A further solution of the present invention is that telescopic pull rods are connected to the tops of the first moving plate and the second moving plate.

[0015] A further solution of the present invention is that a buffer pad is connected to the pushing end of the positioning electric push rod, and a limit inductor electrically connected to the intelligent control component is inlaid at the end of the buffer pad far away from the positioning electric push rod.

[0016] A further solution of the present invention is that the brine tank and the flushing pump are both connected to the first moving plate through a bearing plate. The brine tank is movably inserted into the bearing plate, and a liquid supplement cover is connected to the top of the brine tank.

[0017] A further solution of the present invention is that a supplementary light is connected to the top of the camera and is electrically connected to the intelligent control component.

[0018] A further solution of the present invention is that the intelligent control component includes a control cabinet. A cabinet door is hinged at the opening of the control cabinet.

A bag body connecting head and a hanging joint are connected to the top of the transparent bag body. A bag body liquid discharge head is connected to the bottom of the transparent bag body.

[0021] A further solution of the present invention is that a rotating ring is sleeved outside the mobile plug.

[0022] The beneficial effects of the present invention:

[0023] 1. Flexible movement and reasonable space utilization: The casters installed at the bottom of the first moving plate and the second moving plate endow the entire drainage device with flexible movement performance, enabling it to move easily within the ward. More importantly, the cooperation between the first moving plate and the second moving plate allows all devices to be conveniently moved under the bed. When using the drainage device, it greatly reduces the space occupied by the device in the ward, effectively preventing the drainage device from interfering with the normal nursing work of medical staff. At the same time, it also provides a more spacious and comfortable space for the accompanying work of family members, optimizing the utilization efficiency of the ward environment. The positioning electric push rod can firmly fix the first moving plate after determining the position, ensuring the stability of the drainage process and avoiding affecting the drainage effect due to the movement of the device.

[0024] 2. Equipment integration and easy disinfection: The electric control equipment and the drainage equipment are respectively integrated on the first and second moving plates, with clear functional partitions, facilitating the operation and management of medical staff. After use, the two plates can be separated, and only the second moving plate and the connected drainage equipment are disinfected, improving the disinfection efficiency and reducing the overall disinfection workload and cost.

[0025] 3. Prevention of drainage tube blockage: The intelligent control component regularly controls the flushing pump to flush the double - cavity diversion tube with the brine in the brine tank, timely removing impurities and secretions in the tube, effectively preventing blockage, ensuring smooth drainage, and reducing the pain and risk borne by patients due to re - catheterization.

[0026] 4. Intelligent observation and processing: The camera real - time shoots the liquid collection state of the drainage bag, and transmits the information to the display touch screen through the intelligent control component and the screen wireless communication module. Medical staff can grasp the drainage situation at any time without approaching the patient, improving work efficiency. When draining liquid, by sending instructions through the display touch screen, the intelligent control component controls the external push electric push rod to move out of the moving groove body, facilitating the operation of medical staff, with a high degree of intelligence.

[0027] 5. Reasonable structural design and safe use: The double - cavity diversion tube cooperates with the one - way valve, which not only ensures the normal discharge of the drainage liquid but also prevents the reverse flow of liquid during flushing, avoiding secondary harm to patients. The design of the moving groove body and the liquid collection frame makes the collection and treatment of the drainage liquid more convenient and centralized, reducing the risk of liquid leakage and pollution.

Detailed implementation manners

[0038] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] As Figures 1 to 8 shown, a bedside drainage device for hepatobiliary surgery includes a first moving plate 5. The first moving plate 5 is connected to a second moving plate 21 through a connecting piece 20. Multiple groups of casters 7 are respectively connected to the bottoms of the first moving plate 5 and the second moving plate 21;

[0041] A plurality of positioning electric push rods 8 are inserted at the bottom of the first moving plate 5. The top of the first moving plate 5 is connected with a brine tank 12, a flushing pump 14 connected to the brine tank 12, an intelligent control component 15, a device power supply 16, a support positioning rod 17, and a plug-in slot body 38. The top of the support positioning rod 17 is connected with a camera 18. The plug-in slot body 38 is rotatably connected with a rotating plate 37. The rotating plate 37 is connected with an outward pushing electric push rod 36. The pushing end of the outward pushing electric push rod 36 is connected with a positioning tube 35. The positioning tube 35 is threadedly inserted with a mobile plug 33;

[0042] The top of the second moving plate 21 is connected with a guiding slot body 22. A moving slot body 23 is longitudinally inserted into the guiding slot body 22. The inserted end of the moving slot body 23 is detachably connected with the mobile plug 33. A liquid collecting frame 28 is horizontally inserted into the moving slot body 23. The top of the moving slot body 23 is connected with a connecting rod 25. The connecting rod 25 is hung and connected with drainage bags 29 corresponding to the camera 18 and the liquid collecting frame 28 respectively. The drainage bags 29 are connected with double-chamber diversion tubes 30. One liquid inlet of the double-chamber diversion tube 30 is connected with a drainage tube 32 through a one-way valve 31. The other liquid inlet of the double-chamber diversion tube 30 is connected with the flushing pump 14 through a pipeline;

[0043] The intelligent control component 15 is connected with a display touch screen 2 through a screen wireless communication module 4. The display touch screen 2 is connected with a screen power supply 3. The positioning electric push rods 8, the flushing pump 14, the device power supply 16, the camera 18, and the outward pushing electric push rods 36 are respectively electrically connected with the intelligent control component 15.

[0044] Working principle

[0045] Moving and positioning principle: A plurality of casters 7 installed at the bottoms of the first moving plate 5 and the second moving plate 21 endow the device with flexible moving ability. Medical staff can easily push the device to move according to the position of the patient's hospital bed. When reaching the predetermined position, the intelligent control component 15 issues an instruction to the positioning electric push rod 8, and the positioning electric push rod 8 pushes downward to firmly fix the first moving plate 5 on the ground, ensuring that the device will not displace during the drainage process and guaranteeing the stability of drainage.

[0046] Drainage principle: Connect the drainage tube 32 to the drainage part of the patient. Under the action of the pressure difference, the drainage fluid such as the accumulated fluid and blood in the patient's body flows through the drainage tube 32, passes through the one-way valve 31, and flows into the double-chamber diversion tube 30, and then enters the drainage bag 29 for collection. The one-way valve 31 connected to one liquid inlet of the double-chamber diversion tube 30 only allows the drainage fluid to flow from the drainage tube 32 to the double-chamber diversion tube 30. When the flushing pump 14 flushes the double-chamber diversion tube 30, the one-way valve 31 can prevent the flushing liquid from flowing back, avoiding adverse effects on the patient.

[0047] Anti-clogging principle: The intelligent control component 15 controls the start of the flushing pump 14 at regular intervals according to a pre-set time program. The flushing pump 14 extracts brine from the brine tank 12 and injects it into the double-chamber diversion tube 30 through a pipeline. The impact force of the brine is used to flush the inner wall of the double-chamber diversion tube 30, removing impurities such as attached tissue fragments and blood clots, keeping the double-chamber diversion tube 30 unclogged, and ensuring the smooth progress of the drainage work.

[0048] Drainage fluid observation principle: The camera 18 at the top of the support and positioning rod 17 captures the liquid collection state of the drainage bag 29 in real time, obtaining image information such as the amount, color, and properties of the liquid in the drainage bag 29. The camera 18 transmits the captured content to the intelligent control component 15. After the intelligent control component 15 processes the image information, it sends the data to the display touch screen 2 through the screen wireless communication module 4. Medical staff can clearly view the liquid collection situation of the drainage bag 29 at a position away from the hospital bed, timely grasp the changes in the patient's condition, and improve work efficiency.

[0049] Drainage principle: When the liquid in the drainage bag 29 reaches a certain amount and needs to be drained, medical staff operate and input a drainage instruction on the display touch screen 2. The display touch screen 2 transmits the instruction to the intelligent control component 15 through the screen wireless communication module 4. The intelligent control component 15 starts the external push electric push rod 36. The pushing end of the external push electric push rod 36 pushes the positioning tube 35. The positioning tube 35 drives the moving plug 33 threadedly connected to it. The moving plug 33 pushes the moving groove body 23 out of the guiding groove body 22 to a position convenient for operation. At this time, the drainage switch of the drainage bag 29 is opened, and the drainage fluid flows into the liquid collection frame 28 horizontally inserted into the moving groove body 23, completing centralized collection and facilitating subsequent unified treatment. After use, the first moving plate 5 and the second moving plate 21 can be separated through the connecting member 20, and the second moving plate 21 connected to the drainage device can be disinfected separately for the next use.

[0050] Embodiment 2

[0051] As Figures 1 to 8 shown, a bedside drainage device for hepatobiliary surgery includes a first moving plate 5. The first moving plate 5 is connected to a second moving plate 21 through a connecting member 20. Multiple groups of casters 7 are respectively connected to the bottoms of the first moving plate 5 and the second moving plate 21;

[0052] Multiple groups of positioning electric push rods 8 are inserted into the bottom of the first moving plate 5. The top of the first moving plate 5 is connected with a brine tank 12, a flushing pump 14 connected to the brine tank 12, an intelligent control component 15, an equipment power supply 16, a support and positioning rod 17, and a plug-in slot body 38. The top of the support and positioning rod 17 is connected with a camera 18. The plug-in slot body 38 is rotatably connected with a rotating plate 37. The rotating plate 37 is connected with an external push electric push rod 36. The pushing end of the external push electric push rod 36 is connected with a positioning tube 35. The positioning tube 35 is threadedly inserted with a moving plug 33;

[0053] A guide groove body 22 is connected to the top of the second moving plate 21. A moving groove body 23 is longitudinally inserted into the guide groove body 22. The inserted end of the moving groove body 23 is detachably connected to the moving plug 33. A liquid collecting frame 28 is horizontally inserted into the moving groove body 23. A connecting rod 25 is connected to the top of the moving groove body 23. The connecting rod 25 is connected by a hanging buckle to drainage bags 29 corresponding to the camera 18 and the liquid collecting frame 28 respectively. The drainage bags 29 are connected to a double-chamber diversion tube 30. One liquid inlet of the double-chamber diversion tube 30 is connected to a drainage tube 32 through a one-way valve 31. The other liquid inlet of the double-chamber diversion tube 30 is connected to the flushing pump 14 through a pipeline;

[0054] The intelligent control component 15 is connected to a display touch screen 2 through a screen wireless communication module 4. The display touch screen 2 is connected to a screen power supply 3. The positioning electric push rod 8, the flushing pump 14, the device power supply 16, the camera 18, and the outward push electric push rod 36 are respectively electrically connected to the intelligent control component 15.

[0055] The display touch screen 2 is connected to a hanging buckle plate 1. The screen power supply 3 and the screen wireless communication module 4 are both fixedly connected to the hanging buckle plate 1.

[0056] The advantages of the above settings are as follows:

[0057] Convenient installation and disassembly: The display touch screen 2 is connected through the hanging buckle plate 1. Compared with traditional fixed installation, it can be quickly installed and disassembled without complex tools and cumbersome processes. When maintaining the equipment, adjusting the position, or repairing faults, medical staff can easily remove or reinstall the display touch screen 2 from the hanging buckle plate 1, significantly improving the operation efficiency and reducing the time and labor costs consumed by equipment installation and disassembly.

[0058] Rational use of space: The hanging buckle plate 1 can be flexibly installed on the ward wall, the guardrail of the hospital bed, etc., enabling the display touch screen 2 to get rid of the restriction of the desktop space. It can adjust the height and angle according to actual needs, facilitating medical staff and patients to watch and operate. This design avoids the display touch screen 2 occupying the limited desktop space beside the hospital bed, making room for other medical equipment or items, optimizing the ward space layout, and creating a clean and orderly environment.

[0059] Orderly line management: The screen power supply 3 and the screen wireless communication module 4 are both fixedly connected to the hanging buckle plate 1, and the relevant lines can be concentrated and fixed in the area near the hanging buckle plate 1. In this way, it is convenient to uniformly manage and organize the lines, effectively avoiding the situation of line entanglement and chaos, reducing the risk of faults such as short circuits and poor contact caused by line chaos, and at the same time facilitating the inspection and maintenance of the lines.

[0060] Improved safety: The stable positioning connection of the hanging plate 1 ensures that the display touch screen 2 is not easy to shake or fall during use, ensuring stable operation of the equipment. At the same time, the reasonable connection between the screen power supply 3, the screen wireless communication module 4 and the hanging plate 1, combined with orderly line management, reduces safety hazards such as tripping and electric shock, creating a safer use environment for medical staff and patients.

[0061] The tops of the first movable plate 5 and the second movable plate 21 are both connected with telescopic pull rods 6 .

[0062] The advantages of the above settings are:

[0063] Convenient for mobile control: The telescopic pull rod 6 connected to the top of the first movable plate 5 and the second movable plate 21 provides a convenient point of force for medical staff to move the drainage device. Compared with directly pushing the plate surface, applying force through the pull rod is more ergonomic and can more easily control the moving direction and speed of the device, especially in narrow ward corridors or when the device needs to be accurately positioned, it can effectively prevent the device from colliding with obstacles such as beds and walls, thereby improving the flexibility and accuracy of mobile operations.

[0064] Adapt to different scene requirements: The telescopic rod 6 can be adjusted in length according to the actual use scene and the height of the user. When the device needs to be moved to the bottom of the bed for storage, the rod can be shortened to reduce the space occupied; when the device needs to be moved over a long distance or the medical staff is tall, the extended rod can make the operation more comfortable and labor-saving, meet the use requirements in a variety of scenes, and improve the versatility of the device.

[0065] Improved operating comfort: During long-term or frequent movement of the drainage device, the telescopic pull rod 6 can effectively reduce the fatigue of medical staff who bend over or lean over to operate. By adjusting the pull rod to a suitable height, medical staff can maintain a relatively upright and comfortable posture to push the device, reducing the risk of strain on the waist, arms and other parts, which helps to improve the working experience of medical staff.

[0066] Save space: When not in use, the telescopic rod 6 can be retracted to the shortest state, close to the top of the first movable plate 5 and the second movable plate 21, without adding extra space to the device, ensuring that the device can still maintain a compact shape when idle, which is easy to store and manage, and is particularly suitable for ward environments with limited space.

[0067] Enhanced safety: The setting of the telescopic pull rod 6 makes the moving process of the device more stable and controllable, reducing the risk of the device tipping over, component damage or drainage tube pulling due to improper operation, ensuring patient safety and normal operation of the equipment. At the same time, the stable moving operation also reduces the possibility of medical staff being injured during the handling process.

[0068] The pushing end of the positioning electric push rod 8 is connected with a buffer pad 9, and a limit inductor 10 electrically connected to the intelligent control component 15 is inlaid at the end of the buffer pad 9 away from the positioning electric push rod 8.

[0069] The advantages of the above settings are as follows:

[0070] Protection device and the ground: The buffer pad 9 connected to the pushing end of the positioning electric push rod 8 can effectively buffer the impact force between the push rod and the ground when the positioning electric push rod 8 pushes down to fix the first moving plate. It avoids the direct hard contact between the positioning electric push rod 8 and the ground, prevents the ground from being worn and the end of the push rod from being damaged, protects the ward floor facilities, extends the service life of the positioning electric push rod 8, and reduces the equipment maintenance cost.

[0071] Achieve precise positioning: The limit inductor 10 inlaid at the end of the buffer pad 9 away from the positioning electric push rod 8 can sense the contact state between the buffer pad 9 and the ground or other positioning surfaces in real time and feed back the signal to the intelligent control component 15. When the buffer pad 9 touches the positioning surface and reaches the set pressure or position, the limit inductor 10 triggers a signal, and the intelligent control component 15 timely controls the positioning electric push rod 8 to stop working, ensuring that the first moving plate is precisely fixed at the positioning point, avoiding damage to the device caused by excessive downward pressure or inaccurate positioning, and improving the working stability of the drainage device.

[0072] Enhance safety protection: The combined setting of the buffer pad 9 and the limit inductor 10 can effectively prevent the positioning electric push rod 8 from overextending due to out-of-control or failure, avoid collision damage to surrounding personnel and equipment, and prevent the device's own structure from being damaged due to excessive force. For example, in case of misoperation or system failure, the limit inductor 10 can quickly respond and cut off the power supply of the positioning electric push rod 8 to ensure use safety.

[0073] Improve equipment reliability: Through the buffering of the buffer pad 9 and the precise control of the limit inductor 10, the impact and wear of the positioning electric push rod 8 during the working process are reduced, the probability of equipment failure is lowered, the drainage device maintains stable and reliable performance during long-term use, provides continuous and effective support for the drainage work in hepatobiliary surgery, and reduces the impact on patient treatment caused by equipment instability.

[0074] The saline water tank 12 and the flushing pump 14 are both connected to the first moving plate 5 through the bearing plate 11. The saline water tank 12 is movably inserted into the bearing plate 11, and a liquid supplement cover 13 is connected to the top of the saline water tank 12.

[0075] The advantages of the above settings are as follows:

[0076] Convenient for equipment installation and maintenance: The saline tank 12 and the flushing pump 14 are connected to the first movable plate 5 through the bearing plate 11. This modular installation method makes the installation and disassembly of the two more convenient. When the equipment fails, medical staff do not need to disassemble the entire drainage device in a complicated manner. They only need to separate the bearing plate 11 from the first movable plate 5 to inspect and replace the saline tank 12 or the flushing pump 14 separately, which greatly reduces the difficulty of maintenance, shortens the maintenance time, and improves the maintainability of the equipment.

[0077] Convenient saline refill and management: The saline tank 12 is movably connected to the carrier plate 11, so that the saline tank 12 can be easily removed. When the saline in the tank is insufficient, medical staff can quickly remove the saline tank 12 for fluid replenishment. Compared with the fixed saline tank, this method does not require operation in situ, reducing the inconvenience caused by space limitations. At the same time, the design of the fluid replenishment cover 13 on the top of the saline tank 12 further ensures the sealing of the fluid replenishment process, prevents saline from spilling or external impurities from entering the tank, and ensures the cleanliness and effectiveness of the flushing saline.

[0078] Optimize spatial layout and stability: The load-bearing plate 11, as a connecting component, can reasonably arrange the brine tank 12 and the flushing pump 14, so that the installation of the two on the first movable plate 5 is more compact and orderly, effectively utilizing the space, and avoiding the overall stability of the device being affected by the messy placement of the equipment. The load-bearing plate 11 provides a stable support for the brine tank 12 and the flushing pump 14, enhances the stability of the equipment during movement or operation, reduces the risk of component damage caused by shaking, and ensures the normal operation of the drainage device.
