Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a tumor care fluid drainage device. Background Technology

[0002] In the clinical care of tumors, some tumor patients (such as those with abdominal or thoracic tumors) may experience fluid retention. If the fluid cannot be drained in a timely and safe manner, it can lead to complications such as chest tightness, abdominal distension, or infection, which can seriously affect the patient's recovery process. Therefore, fluid drainage devices are one of the core auxiliary devices in tumor care.

[0003] Currently, traditional tumor care fluid drainage devices often suffer from problems such as unreasonable structural design, limited functionality, and poor safety and convenience. Firstly, most devices only have basic drainage functions and lack precise flow rate adjustment mechanisms. Excessive flow rate can easily cause dizziness and nausea in patients, while insufficient flow rate prevents timely drainage of fluid. Furthermore, the lack of flow rate locking function makes them susceptible to fluctuations due to external interference. Secondly, monitoring of fluid collection volume relies on manual observation by medical staff, lacking real-time monitoring and full-volume warning mechanisms, making fluid overflow highly likely and causing environmental cross-infection or patient skin irritation. Thirdly, emergency protection capabilities are weak. When the device is shaken, pulled, or the drainage catheter is accidentally dislodged, it cannot quickly stop the flow, leading to fluid leakage and further increasing nursing risks.

[0004] In addition, the traditional fluid drainage devices have independent functional components without coordinated linkage, which not only increases the workload of medical staff, but also fails to fully meet the long-term, safe and comfortable fluid drainage needs of cancer patients.

[0005] Therefore, a tumor care fluid drainage device was developed to address the shortcomings of the aforementioned traditional technologies. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a tumor care fluid drainage device that overcomes the technical shortcomings of traditional tumor care fluid drainage devices, such as uncontrollable flow rate, lack of real-time monitoring and early warning for fluid collection, inability to quickly stop flow in case of emergencies, and lack of coordinated operation among components. This device achieves precise, safe, and convenient fluid drainage, reduces the workload of medical staff, improves the safety and comfort of tumor patients during fluid drainage, and meets the needs of long-term clinical care.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A tumor care fluid drainage device includes a device body, on which a fluid collection chamber, a drainage conduit, and a fixing component are provided. The fluid collection chamber is embedded inside the device body. One end of the drainage conduit is connected to the fluid collection chamber, and the other end of the drainage conduit is used to connect to the patient's fluid accumulation site. The fixing component is integrally formed with the device body. The device body is also provided with a flow rate regulating component for regulating the flow rate of fluid drainage, a monitoring component for real-time monitoring of the fluid collection volume, and an emergency flow-stopping component for quickly stopping the flow and preventing fluid leakage in case of accidental tube dislodgement or shaking. The flow rate regulating component is installed at the connection between the drainage conduit and the fluid collection chamber. The monitoring component is installed inside the fluid collection chamber. The emergency flow-stopping component is installed on the drainage conduit. The monitoring component is signal-connected to a control module. The control module is signal-connected to the flow rate regulating component and the emergency flow-stopping component.

[0008] When the control module determines that the monitoring component detects that the amount of liquid in the liquid collection chamber has reached the preset full threshold, the control module controls the flow rate adjustment component to lock the flow rate and triggers an early warning prompt from the monitoring component.

[0009] When the control module determines that the emergency flow-stopping component detects that the device shaking amplitude exceeds the preset threshold or the drainage tube is accidentally dislodged, the control module controls the emergency flow-stopping component to quickly close the drainage tube, and at the same time controls the monitoring component to issue an early warning.

[0010] Furthermore, the flow rate regulation component includes a regulating valve core, a driving component, and a flow rate sensor. The regulating valve core is embedded at the connection between the drainage conduit and the effluent collection chamber. The outer peripheral wall of the regulating valve core is provided with uniformly distributed stepped threaded grooves. The driving component is fixedly connected to the regulating valve core, and both the driving component and the flow rate sensor are signal-connected to the control module. The flow rate sensor is installed inside the drainage conduit. The flow rate sensor is used to detect the effluent discharge flow rate in real time. The control module controls the driving component to drive the regulating valve core to rotate according to the effluent discharge flow rate.

[0011] Furthermore, the monitoring component includes a float-type liquid level sensor, which is movably embedded inside the liquid collection chamber. The float-type liquid level sensor includes a float, a liquid level transmission rod, and a signal transmitter. The float is fixedly connected to the liquid level transmission rod, and the signal transmitter is connected to the end of the liquid level transmission rod away from the float. The signal transmitter is also connected to the control module. The float is used to float up and down with the change in the amount of liquid collected, thereby driving the liquid level transmission rod to move synchronously. The signal transmitter is used to convert the liquid level signal into an electrical signal and feed it back to the control module. When the liquid level reaches a preset full-capacity threshold, the control module triggers an early warning.

[0012] Furthermore, the monitoring component is connected to an early warning component, which is embedded in the top of the main body of the device. The early warning component includes an indicator light and a buzzer, both of which are connected to the control module. When the liquid accumulation reaches the preset full-volume threshold, the emergency flow-stopping component detects excessive shaking or accidental pipe disconnection, the control module simultaneously triggers the indicator light to light up and the buzzer to sound an alarm.

[0013] Furthermore, the fixing components include a flexible fixing strap, a metal elastic wire, a toothed buckle, and a tension sensor. The flexible fixing strap is symmetrically fixed to both sides of the device body. The metal elastic wire is embedded inside the flexible fixing strap and is used to enhance the support of the flexible fixing strap. The toothed buckle is fixedly connected to one end of the flexible fixing strap, and the side of the device body is provided with a slot that matches the toothed buckle. The tension sensor is installed inside the flexible fixing strap and is connected to the control module. The tension sensor is used to detect the tension of the fixing strap in real time.

[0014] Furthermore, it also includes an interface adaptive adjustment component, which is located at the end of the drainage catheter near the patient's fluid accumulation site. The interface adaptive adjustment component includes a three-jaw adaptive chuck, an elastic sealing sleeve, an adjusting ring, and an interface pressure sensor. The three-jaw adaptive chuck is fixedly connected to the drainage catheter. The elastic sealing sleeve is nested at the connection between the three-jaw adaptive chuck and the drainage catheter. The adjusting ring is sleeved on the outer periphery of the three-jaw adaptive chuck, and the adjusting ring and the jaws of the three-jaw adaptive chuck are driven by inclined surface engagement. The interface pressure sensor is installed on the inner side of the jaws of the three-jaw adaptive chuck and is signal-connected to the control module. The interface pressure sensor is used to detect the contact pressure between the jaws of the three-jaw adaptive chuck and the interface.

[0015] Furthermore, the emergency flow control assembly includes a flow control valve, a sway sensor, and a disconnection detection pin. The flow control valve is installed on the drainage conduit and includes a valve seat, a valve disc, and a power component. The valve disc is movably embedded inside the valve seat, and the power component is fixedly connected to the valve disc and connected to the control module via signal. The sway sensor is installed inside the main body of the device and is connected to the control module via signal. The sway sensor is used to detect the sway amplitude of the device in real time. The disconnection detection pin is movably embedded inside the three-jaw adaptive chuck. One end of the disconnection detection pin is connected to the control module via signal, and the other end of the disconnection detection pin is used to abut against the drainage device interface.

[0016] Furthermore, it also includes a buffer pad and a return spring. The buffer pad has a built-in honeycomb elastic structure, one end of the return spring is fixedly connected to the buffer pad, and the other end of the return spring is fixedly connected to the inner wall of the main body of the device.

[0017] Furthermore, a detachable drain valve is provided at the bottom of the liquid collection chamber. A pull rope connects the drain valve to the liquid level transmission rod of the monitoring component. When the liquid level transmission rod rises to the full threshold, the drain valve is pulled by the pull rope, thereby putting the drain valve in the ready-to-open state.

[0018] Furthermore, it also includes a power module, which is installed inside the main body of the device.

[0019] The above approach has the following beneficial effects:

[0020] 1. This solution coordinates the flow rate adjustment component, monitoring component, and emergency flow control component through a control module, achieving precise flow rate adjustment, full-volume warning, and coordinated flow control for fluid drainage. Compared with traditional tumor care fluid drainage devices, which are mostly single-function drainage devices with independent operation of each component and no coordinated design, this solution effectively solves the core pain points of traditional devices, such as uncontrollable flow rate, lack of indication when the fluid is full and easy to overflow, and leakage of fluid when the tube is accidentally dislodged or shaken. The accuracy of flow rate adjustment is significantly improved, and the flow control response is rapid, greatly enhancing the safety and accuracy of fluid drainage and reducing safety hazards in clinical nursing.

[0021] 2. This solution integrates auxiliary components such as an interface adaptive adjustment component, a buffer pad and a return spring, and a detachable drainage valve. Each auxiliary component is linked and compatible with the core component. Compared with traditional liquid drainage devices that have a single interface specification, no skin protection structure, and require disassembly for cumbersome drainage, this solution can be adapted to different models of drainage devices without additional adapters. At the same time, it can effectively disperse local skin pressure and avoid pressure injury from long-term wear. It can be operated quickly without disassembling the device during drainage, which significantly improves the clinical adaptability, wearing comfort and operation convenience of the device, and reduces the workload of medical staff.

[0022] 3. This solution adopts a dual design of electronic control coordination and mechanical linkage. The core linkage structure does not require complex electronic control components. It relies on conventional mechanical parts and simple electronic control to achieve multiple functions. Moreover, the fixed components and the main body of the device are integrally molded, and the integration of each component is high. Compared with the redundant structure, scattered parts, easy damage and inconvenient maintenance of traditional liquid discharge devices, the device is lightweight, more stable, and has a significantly reduced failure rate. It is also easy to disassemble and clean and can be reused, which reduces production and maintenance costs and enhances the clinical application value of the device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The following detailed description illustrates the specific implementation method:

[0033] Example 1:

[0034] As attached Figures 1 to 5As shown: A tumor care fluid drainage device includes a main body 1, on which a fluid collection chamber 2, a drainage conduit 3, and a fixing component are provided. The fluid collection chamber 2 is embedded inside the main body 1. One end of the drainage conduit 3 is connected to the fluid collection chamber 2, and the other end of the drainage conduit 3 is used to connect to the patient's fluid accumulation site. The fixing component is integrally formed with the main body 1. The main body 1 is also provided with a flow rate regulating component for adjusting the fluid drainage flow rate, a monitoring component for real-time monitoring of the fluid collection volume, and an emergency flow-stopping component for quickly stopping the flow and preventing fluid leakage in case of accidental tube dislodgement or shaking. The flow rate regulating component is installed at the connection between the drainage conduit 3 and the fluid collection chamber 2. The monitoring component is installed inside the fluid collection chamber 2. The emergency flow-stopping component is installed on the drainage conduit 3. The monitoring component is signal-connected to a control module, and the control module is signal-connected to the flow rate regulating component and the emergency flow-stopping component.

[0035] When the control module determines that the monitoring component detects that the amount of liquid in the liquid collection chamber 2 has reached the preset full threshold, the control module controls the flow rate adjustment component to lock the flow rate and triggers the monitoring component to issue an early warning. When the control module determines that the emergency stop component detects that the device shaking amplitude exceeds the preset threshold or the drainage tube 3 is accidentally dislodged, the control module controls the emergency stop component to quickly close the drainage tube 3 and controls the monitoring component to issue an early warning.

[0036] The flow rate regulation assembly includes a regulating valve core 4, a drive component 5, and a flow rate sensor. In this embodiment, the drive component 5 is a motor. The regulating valve core 4 is embedded at the connection between the drainage conduit 3 and the effluent collection chamber 2. The outer peripheral wall of the regulating valve core 4 is provided with uniformly distributed stepped threaded grooves. The drive component 5 is fixedly connected to the regulating valve core 4, and both the drive component 5 and the flow rate sensor are signal-connected to the control module. The flow rate sensor is installed inside the drainage conduit 3. The flow rate sensor is used to detect the effluent discharge flow rate in real time. The control module controls the drive component 5 to drive the regulating valve core 4 to rotate according to the effluent discharge flow rate.

[0037] The monitoring component includes a float-type liquid level sensor, which is movably embedded inside the liquid collection chamber 2. The float-type liquid level sensor includes a float 6, a liquid level transmission rod 7, and a signal transmitter. The float 6 is fixedly connected to the liquid level transmission rod 7, and the signal transmitter is connected to the end of the liquid level transmission rod 7 away from the float 6. The signal transmitter is also connected to the control module. The float 6 is used to float up and down with the change in the amount of liquid collected, thereby driving the liquid level transmission rod 7 to move synchronously. The signal transmitter is used to convert the liquid level signal into an electrical signal and feed it back to the control module. When the liquid level reaches the preset full-capacity threshold, the control module triggers an early warning.

[0038] The fixing components include a flexible fixing band 8, a metal elastic wire, a toothed buckle 9, and a tension sensor. The flexible fixing band 8 is symmetrically fixed to both sides of the main body 1 of the device. The metal elastic wire is embedded inside the flexible fixing band 8 and is used to enhance the support of the flexible fixing band 8. The toothed buckle 9 is fixedly connected to one end of the flexible fixing band 8. The side of the main body 1 of the device is provided with a slot that matches the toothed buckle 9. The tension sensor is installed inside the flexible fixing band 8 and is connected to the control module. The tension sensor is used to detect the tension of the fixing band in real time.

[0039] The emergency flow control assembly includes a flow control valve, a sway sensor, and a detachment detection pin. The flow control valve is installed on the drainage conduit 3 and includes a valve seat, a valve disc, and a power component. The valve disc is movably embedded inside the valve seat, and the power component is fixedly connected to the valve disc and connected to the control module via signal. The sway sensor is installed inside the main body 1 of the device and is connected to the control module via signal. The sway sensor is used to detect the sway amplitude of the device in real time. One end of the detachment detection pin is connected to the control module via signal, and the other end of the detachment detection pin is used to contact the drainage equipment interface.

[0040] It also includes a power module, which is installed inside the main body 1 of the device. The power module is connected to the control module, flow rate regulation component, monitoring component, emergency flow stop component, fixing component and early warning component by signal, and provides stable power supply to each component.

[0041] The specific implementation process is as follows: First, medical staff pre-process the device. Based on the clinical needs of the patient's fluid accumulation site (such as the abdominal cavity or pleural cavity), the core parameters are preset through the control module, including the full-volume threshold of the fluid collection chamber 2 and the device shaking warning threshold. After the preset is completed, the end of the drainage catheter 3 furthest from the main body 1 is connected to the patient's fluid accumulation site. At the same time, the drainage device interface is connected to the corresponding end of the drainage catheter 3, ensuring that the dislodgement detection pin is in tight contact with the drainage device interface, so that the dislodgement detection pin is in a compressed state. At this time, the dislodgement detection pin sends an electrical signal to the control module indicating that the interface is properly connected. After receiving the signal, the control module controls the stop valve of the emergency stop component to remain open, preparing for fluid drainage.

[0042] Next, the flexible fixation strap 8 is wrapped around the patient's wearing area (such as the waist or chest). Based on the patient's body shape, the engagement position of the toothed buckle 9 with the side groove of the device body 1 is adjusted to achieve stepless tension adjustment of the flexible fixation strap 8. During this process, the tension sensor inside the flexible fixation strap 8 detects the tension of the strap in real time and continuously feeds the tension signal back to the control module. The control module determines whether the tension is appropriate based on a preset tension range threshold. If the tension is lower than the lower limit of the tension range threshold (too loose), the control module controls the monitoring component to trigger a preliminary warning, prompting medical staff to adjust the buckle position to prevent the device from shaking or falling off during movement due to being too loose. If the tension is higher than the upper limit of the tension range threshold (too tight), the control module also triggers a preliminary warning, reminding medical staff to loosen the fixation strap to avoid pulling on the patient's skin due to excessive tightness. The flexible fixation strap 8 contains metal elastic wires that provide support, ensuring stability while preventing strap deformation and providing comfort. Compared to existing fixation components that only offer a single fixation function, this invention effectively solves the problems of existing devices lacking a lightweight fixation structure and being prone to shaking and falling off. It also avoids the risks of being too tight or too loose, improving the safety and comfort of clinical wear.

[0043] After fixation, the drainage catheter 3 guides the accumulated fluid in the patient's body to the fluid collection chamber 2. During this process, the flow rate regulation component works throughout. The flow rate sensor inside the drainage catheter 3 detects the fluid discharge flow rate in real time and converts the flow rate signal into an electrical signal, which is then fed back to the control module. The control module compares the real-time flow rate with the preset target flow rate. If the real-time flow rate is lower than the preset value, the control module controls the drive component 5 (motor) to rotate forward, causing the regulating valve core 4 to rotate synchronously. By changing the engagement depth between the stepped threaded groove on the outer peripheral wall of the regulating valve core 4 and the inner wall of the drainage catheter 3, the cross-sectional area of ​​the drainage channel is increased, thereby increasing the fluid discharge flow rate. If the real-time flow rate is higher than the preset value, the control module controls the drive component 5 to rotate in the reverse direction, causing the regulating valve core 4 to rotate in the reverse direction, reducing the cross-sectional area of ​​the drainage channel and decreasing the discharge flow rate until the real-time flow rate matches the preset target flow rate. At this point, the drive component 5 stops working and remains in a self-locking state to ensure stable flow rate. By combining the stepped threaded groove design of the regulating valve core 4, the flow rate of the effluent discharge can be precisely adjusted. The adjustment accuracy is improved compared with the conventional smooth threaded valve core. It effectively solves the technical defects of the existing device, such as the inability to precisely adjust the flow rate and the tendency to cause dizziness, nausea and other discomfort in patients due to excessive flow rate. It can adapt to the effluent drainage needs of different patients and improve the pertinence of clinical care.

[0044] During the drainage process, the float 6 inside the drainage collection chamber 2 floats upward synchronously with the increase in drainage volume, causing the liquid level transmission rod 7 to rise synchronously. The signal transmitter at the end of the liquid level transmission rod 7 converts the liquid level signal into an electrical signal, which is continuously fed back to the control module. The control module judges in real time whether the liquid level has reached the preset full-capacity threshold. When the drainage volume has not reached the threshold, the monitoring component maintains normal monitoring status, the flow rate regulation component maintains the preset flow rate, the emergency stop component remains open, and the device drains normally. When the drainage volume reaches the preset full-capacity threshold, the control module immediately performs a dual linkage operation: first, it locks the drive component 5 of the flow rate regulation component, prohibiting the rotation of the regulating valve core 4, thereby locking the flow rate and preventing continued drainage from causing drainage overflow that could pollute the environment or cause cross-infection; second, it triggers the warning prompt of the monitoring component, reminding medical staff to deal with the drainage in a timely manner. This overcomes the limitation of existing devices where monitoring and flow rate regulation are independent, solving the defect of no full-capacity warning and further ensuring drainage safety through flow rate locking.

[0045] Throughout the entire drainage process, the emergency drainage component remains on standby. The shaking sensor inside the main body 1 detects the shaking amplitude of the device in real time and feeds the shaking signal back to the control module. When the patient turns over or moves normally and the shaking amplitude does not exceed the preset threshold, the emergency drainage component remains open and does not affect normal drainage. When the patient moves violently or is accidentally bumped, causing the device to shake beyond the preset threshold, the control module immediately controls the power component of the emergency drainage component to close the valve disc of the drainage valve quickly, closing the drainage tube 3 to prevent the drainage tube 3 from falling off and causing leakage of fluid due to violent shaking. At the same time, the control module triggers an alarm to remind medical staff to check the status of the device.

[0046] If the drainage device interface accidentally becomes detached, the detachment detection pin loses its contact force, and the control module quickly responds by controlling the stop valve to close, thus quickly stopping the flow and preventing continuous leakage of fluid that could contaminate clothing and hospital beds. At the same time, an alarm is triggered to notify medical staff to reconnect the interface in a timely manner.

[0047] After the drainage procedure is completed, medical staff disconnect the drainage catheter 3 from the patient's fluid accumulation site, disassemble the fixing components, and clean and disinfect the device for future reuse.

[0048] Example 2:

[0049] The difference from Embodiment 1 is that the monitoring component is connected to an early warning component, which is embedded in the top of the main body 1 of the device. The early warning component includes an indicator light and a buzzer, both of which are connected to the control module. When the liquid accumulation reaches the preset full threshold, the emergency flow stop component detects that the shaking exceeds the threshold, or the tube is accidentally dislodged, the control module simultaneously triggers the indicator light to light up and the buzzer to sound an alarm.

[0050] The specific implementation process is as follows: During drainage, the early warning component, monitoring component, and emergency flow control component work together to respond to abnormal situations in real time. When the monitoring component detects that the accumulated fluid volume reaches the preset full-volume threshold, or when the emergency flow control component detects that the device shaking exceeds the threshold or the drainage catheter 3 is accidentally dislodged, the control module immediately triggers the early warning component to activate. The indicator light illuminates, and the buzzer sounds an alarm, providing a clear and intuitive warning signal to medical staff. Medical staff can quickly identify the type of abnormality through the indicator light, promptly handle the accumulated fluid, adjust the device's fixation, or reconnect the catheter. After handling, the control module automatically triggers the early warning component to reset and return to standby mode. The newly added early warning component in this embodiment overcomes the limitation of existing devices that only provide single feedback on abnormalities. It adopts a dual warning mode of light and sound, solving the shortcomings of existing devices where warnings are not intuitive and medical staff are prone to missing abnormalities. This significantly shortens the response time for medical staff and reduces nursing risks.

[0051] Example 3:

[0052] As attached Figure 1 As shown, the difference from Embodiment 2 is that it also includes an interface adaptive adjustment component. The interface adaptive adjustment component is located at the end of the drainage catheter 3 near the patient's fluid accumulation site. The interface adaptive adjustment component includes a three-jaw adaptive chuck 10, an elastic sealing sleeve, an adjusting ring 11, and an interface pressure sensor. The three-jaw adaptive chuck 10 is fixedly connected to the drainage catheter 3. The elastic sealing sleeve is nested at the connection between the three-jaw adaptive chuck 10 and the drainage catheter 3. The adjusting ring 11 is sleeved on the outer periphery of the three-jaw adaptive chuck 10, and the adjusting ring 11 and the jaws of the three-jaw adaptive chuck 10 are driven by inclined surface engagement. The interface pressure sensor is installed on the inner side of the jaws of the three-jaw adaptive chuck 10. The interface pressure sensor is connected to the control module and is used to detect the contact pressure between the jaws of the three-jaw adaptive chuck 10 and the interface. The tube dislodgement detection pin is movably embedded in the inner side of the three-jaw adaptive chuck 10.

[0053] The specific implementation process is as follows: Align the drainage device interface with the center of the three-jaw adaptive chuck 10 and slowly push it in until the interface contacts the dislodgement detection pin on the inner side of the three-jaw adaptive chuck 10, until the dislodgement detection pin is completely compressed. Subsequently, medical staff manually rotate the adjusting ring 11, using the inclined surface meshing transmission between the adjusting ring 11 and the jaws to drive the three jaws to retract synchronously towards the center, gradually clamping the drainage device interface. No additional tools are required during the process, making it convenient to operate.

[0054] As the jaws retract and clamp, the elastic sealing sleeve nested at the connection between the jaws and the drainage tube 3 is simultaneously squeezed, tightly fitting the interface and the inner wall of the jaws to form a double seal and prevent fluid leakage. At the same time, the interface pressure sensor on the inner side of the jaws detects the contact pressure between the jaws and the interface in real time and continuously feeds the pressure signal back to the control module. The control module makes a judgment based on the preset contact pressure threshold.

[0055] If the pressure is lower than the preset threshold, the control module triggers an early warning component to prompt medical staff to continue rotating the adjusting ring 11 until the pressure reaches the target. If the pressure is higher than the preset threshold, the early warning component will issue a warning simultaneously to prevent excessive pressure from damaging the drainage device interface or clamps. After docking, the tube detachment detection pin remains in close contact with the interface, and the interface pressure sensor continuously monitors the pressure. If a sudden drop in pressure occurs (interface loosening), a signal is immediately sent to the control module, simultaneously triggering an early warning and emergency flow control.

[0056] When the drainage operation is completed or the drainage equipment needs to be replaced, rotate the adjusting ring 11 in the opposite direction to drive the claws to expand outward synchronously, loosening the interface for easy disassembly. The elastic sealing sleeve automatically resets, facilitating subsequent cleaning. Throughout the process, the interface adaptive adjustment component achieves multi-specification interface adaptation through inclined surface meshing transmission. Combined with pressure monitoring and sealing linkage, no additional adapters are required, adapting to different models of drainage equipment and ensuring docking stability and sealing.

[0057] Example 4:

[0058] The difference from Embodiment 3 is that it also includes a buffer pad and a return spring. The buffer pad has a built-in honeycomb elastic structure, one end of the return spring is fixedly connected to the buffer pad, and the other end of the return spring is fixedly connected to the inner wall of the device body 1.

[0059] The specific implementation process is as follows: When the device is installed and fixed, the buffer pad is positioned to fit the patient's skin, and the return spring is in a naturally extended state, supporting the buffer pad to maintain a moderate fit with the skin without compressing it and preventing gaps between the device and the skin. During drainage, when the patient's movement causes slight shaking of the device or small changes in the tension of the fixing strap, the return spring simultaneously expands and contracts. Under the elastic force of the return spring, the buffer pad adjusts slightly to follow the skin contour, always maintaining a tight fit. The honeycomb elastic structure built into the buffer pad effectively disperses the local pressure of the device on the skin, and together with the cushioning effect of the return spring, prevents local pressure concentration during long-term wear. When the device is removed, the return spring automatically returns the buffer pad to its initial position, facilitating subsequent reuse. The buffer pad can also be directly wiped clean, making operation convenient. The entire process relies solely on the mechanical cooperation of the buffer pad and the return spring, without the need for additional electrical control, to achieve flexible skin protection and meet the needs of patients for long-term wear.

[0060] Example 5:

[0061] As attached Figure 4 As shown, the difference from embodiment 4 is that the bottom of the liquid collection chamber 2 is provided with a detachable drain valve 13. A pull rope 12 is connected between the drain valve 13 and the liquid level transmission rod 7 of the monitoring component. When the liquid level transmission rod 7 rises to the full threshold, the drain valve 13 is pulled by the pull rope 12, thereby putting the drain valve 13 in the ready-to-open state.

[0062] The specific implementation process is as follows: Before starting the drainage, check the installation status of the drain valve 13 to ensure that it is tightly fitted to the bottom of the fluid collection chamber 2 without any looseness or leakage. At this time, the pull rope 12 is in a naturally relaxed state, and the drain valve 13 remains closed to ensure normal fluid collection. During the drainage process, the liquid level transmission rod 7 of the monitoring component rises synchronously with the increase of the fluid volume. When the fluid reaches the preset full-volume threshold, the liquid level transmission rod 7 continues to rise, pulling the pull rope 12 connected to it. The pull rope 12 is tightened and pulls the valve stem of the drain valve 13, causing the drain valve 13 to switch to the ready-to-open state, without the need for medical staff to manually adjust the pretreatment. After receiving the full-volume prompt from the warning component, medical staff can quickly drain the fluid by directly pressing the drain valve 13 in the ready-to-open state without disassembling the device, making the operation convenient. After the fluid is drained, the liquid level transmission rod 7 descends and resets with the float 6, the pull rope 12 relaxes synchronously, and the drain valve 13 automatically springs back to the closed state, restoring the fluid collection function. For thorough cleaning or maintenance, the drain valve 13 can be directly disassembled, residual fluid removed, and then reinstalled and secured. The entire process is triggered by the mechanical linkage between the liquid level transmission rod 7 and the pull rope 12, eliminating the need for additional electrical control. This adapts to the needs of rapid clinical care and ensures efficient and convenient drainage of accumulated fluid.
