[0037] First embodiment:

[0038] The embodiment of the present invention provides a high negative pressure drainage device integrating single-chamber flushing and multi-slot drainage. Figure 1-12 As shown, the high negative pressure drainage device with single-chamber flushing and multi-slot drainage in one comprises: a shell 1, on which two placement slots 2 are provided, respectively used to place a drainage bottle 3 and a flushing bottle 5, on which a first bottle cap 4 and a second bottle cap 6 are respectively sealed and installed, the first bottle cap 4 is provided with an air suction port 7 and a drainage inlet 8, and the second bottle cap 6 is provided with a liquid outlet pipe 9 and an air supply port 10 extending into the flushing bottle 5; a drainage tube 17 connected to the drainage inlet 8, the drainage tube 17 is provided with a plurality of drainage channels 42, which are used to be inserted into the patient's body for drainage, a flushing tube 18 is provided in the drainage tube 17, one end of the flushing tube 18 extends from one side of the drainage tube 17 to the outside of the drainage tube 17, and is connected to the top of the liquid outlet pipe 9, and the flushing tube 18 is used to transport flushing liquid to flush the inside of the drainage tube 17; a negative pressure component for providing a negative pressure environment for the drainage bottle 3, the negative pressure component is arranged in the shell 1.

[0039] In this embodiment, through innovative design, the blockage problem is effectively handled during use, and the drainage effect is significantly improved. The device mainly includes a shell 1, on which two placement slots 2 are carefully designed, which are used to place the drainage bottle 3 and the flushing bottle 5 respectively. The two bottles are isolated from the outside world by the first bottle cap 4 and the second bottle cap 6 that are sealed, ensuring the airtightness and safety of the device. The first bottle cap 4 is equipped with an air suction port 7 and a drainage inlet 8 for connecting the negative pressure component and the drainage tube 17, while the second bottle cap 6 is provided with a liquid outlet pipe 9 and an air supply port 10 extending to the inside of the flushing bottle 5, providing the necessary channels for the flushing process.

[0040] The drainage tube 17 connected to the drainage inlet 8 of the first bottle cap 4 is one of the core components of the device. A plurality of drainage channels 42 are cleverly arranged inside the drainage tube 17, which can be efficiently inserted into the patient's body for multi-channel drainage. Even if one drainage channel 42 is blocked, the remaining drainage channels 42 can still be used, reducing the influence of the blockage of the drainage tube 17 on the drainage, and greatly improving the drainage efficiency and effect. More importantly, a flushing tube 18 is specially designed inside the drainage tube 17. One end of the flushing tube 18 extends from one side of the drainage tube 17 to the outside, and is closely connected to the top of the liquid outlet tube 9, forming a closed-loop flushing system. During use, the flushing tube 18 can accurately deliver the flushing liquid, and flush the inside of the drainage tube 17 in a timely and effective manner, effectively avoiding the blockage problem, ensuring the unobstructed flow of the drainage tube 17, and thus ensuring the smooth progress of the entire drainage process.

[0041] In order to further enhance the drainage effect, the device is also equipped with a set of negative pressure components, which are cleverly arranged inside the housing 1 and can provide a stable high negative pressure environment for the drainage bottle 3. Through the air suction port 7, the negative pressure component can effectively draw air from the drainage bottle 3 to create an ideal negative pressure state, thereby greatly enhancing the drainage capacity of the drainage tube 17 and accelerating the discharge speed of body fluids.

[0042] In a further preferred embodiment of the present invention, an anti-skid pad is provided in the placement groove 2, and the anti-skid pad is made of rubber material. The drainage bottle 3 and the flushing bottle 5 are placed on the anti-skid pads in the two placement grooves 2 respectively.

[0043] In this embodiment, in order to further improve the stability and safety of the device, an anti-skid pad is specially added in the placement groove 2. The anti-skid pad is made of rubber material. By placing the drainage bottle 3 and the flushing bottle 5 on the anti-skid pads in the two placement grooves 2, accidental sliding during operation is effectively prevented, ensuring the stability of the device in use.

[0044] In a further preferred embodiment of the present invention, the negative pressure assembly includes: a negative pressure pump 11 fixedly mounted on the inner wall at the bottom of the shell 1, the air inlet of the negative pressure pump 11 being connected to an exhaust pipe 12; a mounting tube 14 mounted in the shell 1, the mounting tube 14 being connected to the exhaust pipe 12, and one end of the mounting tube 14 extending to the outside of the shell 1; a first connecting hose 15 connected to one end of the mounting tube 14, the other end of the first connecting hose 15 being connected to the exhaust port 7, for extracting air from the drainage bottle 3; wherein a first air pressure sensor 16 is provided on the mounting tube 14, and the first air pressure sensor 16 is located in the shell 1.

[0045] In this embodiment, the core of the negative pressure assembly is a negative pressure pump 11 fixedly mounted on the inner wall of the bottom of the housing 1. The negative pressure pump 11 is connected to the mounting tube 14 in the housing 1 through the suction pipe 12 on its air inlet, forming a continuous air flow channel from the negative pressure pump to the outside of the housing. One end of the mounting tube 14 extends to the outside of the housing 1, and the other end is tightly connected to the suction port 7 on the drainage bottle 3 through the first connecting hose 15, which realizes the effective extraction of air in the drainage bottle and creates an ideal negative pressure environment for the device.

[0046] In order to accurately control and monitor the negative pressure state, a first air pressure sensor 16 is specially provided on the mounting tube 14. The sensor is located inside the housing 1 and can monitor the air pressure changes in the mounting tube in real time, thereby ensuring that the operating state of the negative pressure pump 11 is always within the optimal range, which not only avoids the discomfort caused by excessive negative pressure to the patient, but also ensures sufficient suction to maintain an efficient drainage effect. This design not only improves the intelligence level of the device, but also provides medical staff with the ability to monitor and adjust negative pressure parameters in real time, greatly improving the accuracy and safety of the operation.

[0047] In a further preferred embodiment of the present invention, the back side of the housing 1 is open, and a back plate 101 is detachably mounted thereon by means of screws, so as to facilitate installation and maintenance of components in the housing 1 after the back plate 101 is removed.

[0048] In this embodiment, in order to facilitate the operation of the installation components and maintenance components inside the housing 1, the back side of the housing 1 is designed to be open. This design is combined with the detachable back plate 101 through screws to achieve convenient opening and closing of the rear of the housing. When it is necessary to inspect, maintain or replace the internal components, the operator can easily remove the back plate 101 to obtain direct access to the internal space of the housing 1, which greatly simplifies the maintenance process and improves maintenance efficiency.

[0049] In a further preferred embodiment of the present invention, a touch screen 25 is embedded on the housing 1 for the staff to set parameters and also for displaying the air pressure value monitored by the first air pressure sensor 16 .

[0050] In this embodiment, in order to provide a more intuitive and convenient operating experience, a touch display screen 25 is embedded in the shell 1. This design allows the staff to set parameters through an intuitive interface, including but not limited to the adjustment of key operating parameters such as negative pressure intensity and flushing frequency, ensuring that the device can be personalized according to different medical needs and patient conditions, thereby improving the accuracy and effectiveness of treatment.

[0051] The touch screen 25 also has a real-time display function, which can clearly display the air pressure values ​​monitored by the first air pressure sensor 16 and the second air pressure sensor 24. This feature is crucial for monitoring the operating status of the device and ensuring the stability and safety of the negative pressure environment. Medical staff can observe the real-time data on the display screen to understand the operating status of the device in a timely manner and respond quickly to possible abnormal conditions, thereby avoiding a decrease in treatment effect or patient discomfort caused by unstable air pressure.

[0052] It should be noted that the connection between the touch display screen 25 and the various electrical components can be easily achieved by those skilled in the art through existing technologies, and will not be described in detail here.

[0053] In a further preferred embodiment of the present invention, a lithium battery 26 is installed in the housing 1 for supplying power to electrical components, and a charging port 27 is provided on the housing 1 for charging the lithium battery 26 .

[0054] In this embodiment, in order to ensure that the device can operate stably in various environments, a lithium battery 26 is carefully installed inside the housing 1 as the main power source for the electrical components inside the device, providing continuous and stable power support for the electrical components in the device. The introduction of the lithium battery 26 frees the high negative pressure drainage device from dependence on fixed power sources, greatly enhancing its application flexibility and convenience in mobile medical scenarios.

[0055] The charging port 27 provided on the housing 1 provides convenience for charging the lithium battery 26. Through the charging port 27, medical staff or equipment managers can easily charge the device to ensure that it has sufficient power for long-term use or continuous operation. This design not only simplifies power management and reduces the risk of equipment downtime due to insufficient power, but also improves the user-friendliness of the device, allowing operators to use the device more efficiently and calmly in a busy medical environment, providing patients with uninterrupted high-quality treatment services.

[0056] The connection method between the lithium battery 26, the charging port 27 and each electrical device is an existing mature technology, which is well known to those skilled in the art and will not be described in detail here.

[0057] In a further preferred embodiment of the present invention, a filtering and sterilization mechanism is also provided between the exhaust pipe 12 and the mounting pipe 14, and the filtering and sterilization mechanism includes: a filter box 13 fixedly installed in the shell 1, the exhaust pipe 12 and the mounting pipe 14 are respectively connected to the pipe interfaces on both sides of the filter box 13, and are connected to the inside of the filter box 13; a filter 38 installed in the filter box 13, for filtering the air extracted from the drainage bottle to isolate bacteria and viruses; a plurality of ultraviolet lamps 39 installed on the inner walls on both sides of the filter box 13, for sterilizing bacteria and viruses on the filter 38 in the filter box 13.

[0058] In this embodiment, in order to effectively prevent the spread of bacteria and viruses during the extraction and treatment of air in the drainage bottle, a filtering and sterilizing mechanism is added between the air extraction pipe 12 and the mounting pipe 14. The core component of this mechanism is a filter box 13 fixedly installed in the housing 1, and the pipe interfaces on both sides thereof are respectively connected to the air extraction pipe 12 and the mounting pipe 14, ensuring the continuity and smoothness of the airflow when passing through the filter box 13. A high-efficiency filter 38 is installed inside the filter box 13, which can finely filter the air extracted from the drainage bottle 3, effectively isolate bacteria, viruses and other microorganisms in the air, prevent them from spreading in the medical environment, and ensure the health and safety of patients and medical staff.

[0059] In addition, multiple ultraviolet lamps 39 are installed on the inner walls of both sides of the filter box 13, which can emit high-intensity ultraviolet rays to deeply disinfect bacteria and viruses on the surface of the filter 38, further strengthening the protective effect of the filtering and sterilization mechanism, and ensuring that the air treated by the filter box 13 reaches a high degree of purification. This design not only significantly improves the biosafety of the device, but also provides a safer and cleaner working environment for medical staff, reduces the risk of cross infection in the medical environment, and improves the hygiene level of the entire medical system and the treatment effect of patients.

[0060] In another embodiment of the present invention, a linkage mechanism for providing driving force for the flushing liquid is also provided in the shell 1, and the linkage mechanism includes: a three-way diverter valve 19 connected to the air outlet end of the negative pressure pump 11, and one end of the three-way diverter valve 19 is connected to a connecting pipe 20; an installation box 21 fixedly installed in the shell 1, the connecting pipe 20 is connected to the installation box 21, and a second air pressure sensor 24 is installed on the installation box 21 to monitor the air pressure in the installation box 21; a second connecting hose 23 connected to the air supply port 10, and the top end of the second connecting hose 23 is connected to a connecting port 22 provided at the bottom of the installation box 21, and the connecting port 22 extends to the outside of the shell 1; a diffusion hopper 28 connected to one end of the three-way diverter valve 19, and the diffusion hopper 28 is adapted to the exhaust port starting from one side of the shell 1.

[0061] In this embodiment, in order to achieve accurate control and efficient delivery of the flushing liquid, a set of linkage mechanisms is added inside the housing 1, the core of which is a three-way diverter valve 19 connected to the air outlet of the negative pressure pump 11. One end of the three-way diverter valve 19 is connected to the installation box 21 through a connecting pipe 20. The installation box 21 is fixed in the housing 1, and a second air pressure sensor 24 is installed thereon for real-time monitoring of the air pressure changes in the box to ensure that the air pressure is within a suitable range, thereby accurately regulating the flow rate and amount of the flushing liquid.

[0062] One end of the second connecting hose 23 is connected to the air delivery port 10, and the other end is connected to the connection port 22 provided at the bottom of the installation box 21. The connection port 22 extends to the outside of the housing 1, forming a direct passage from the installation box 21 to the flushing liquid delivery point. When the negative pressure pump 11 is working, a part of the air flow is guided to the installation box 21 through the regulation of the three-way diverter valve 19, and the increase in the air pressure in the flushing bottle 5 causes the flushing liquid to flow smoothly from the liquid outlet pipe 9 to the flushing pipe 18, thereby realizing the delivery of the flushing liquid.

[0063] In addition, the other end of the three-way diverter valve 19 is connected to a diffusion hopper 28, which is adapted to the exhaust port on one side of the shell 1. When the airflow generated by the negative pressure pump 11 passes through the diffusion hopper 28, the airflow is diffused, reducing the airflow velocity at the exhaust port, reducing the exhaust noise, and ensuring the smooth operation of the device.

[0064] By adjusting the three-way diverter valve 19, the pressure of the gas in the flushing bottle 5 can be adjusted, thereby adjusting the flushing liquid delivery speed.

[0066] In this embodiment, in order to provide flexible adjustment and stable limiting of the angle of the drainage tube 17, a limiting mechanism is specially designed on one side of the housing 1, which is mainly composed of components such as a mounting plate 29, a rubber block 30, a hard sleeve 31, a mounting column 32, a slide bar 33, a stopper 34, a spring 35 and a pin 37. The mounting plate 29 is fixed to one side of the housing 1, and the rubber block 30 is fixedly installed on the side away from the housing 1. The rubber block 30 is provided with a clamping position, which is adapted to the hard sleeve 31 fixedly sleeved on the drainage tube 17. The hard sleeve 31 is clamped at the clamping position, so that the initial fixing and adjustment of the angle of the drainage tube 17 is achieved.

[0067] The mounting post 32 is also fixedly mounted on one side of the housing 1, and a slide rod 33 is slidably mounted on a slide hole on one side of the mounting post 32, and the slide rod 33 can rotate on the slide hole, and one end of the slide rod 33 is fixedly connected to the mounting plate 29, and the other end is fixed with a stopper 34. A spring 35 is slidably sleeved on the slide rod 33, and through the elastic action of the spring 35, the pin rod 37 on the mounting plate 29 can be pinned into the pin groove 36, and at the same time, the drainage tube 17 is ensured to be stable in the adjusted position.

[0068] The pin rod 37 is fixed on the mounting plate 29. One side of the mounting column 32 is provided with a plurality of annular pin grooves 36 distributed at equal intervals. The pin rod 37 can be inserted into the pin groove 36. By cooperating with the pin rod 37 and different pin grooves 36, the position of the mounting plate 29 can be further fixed, thereby achieving the fixation of the angle of the drainage tube 17.

[0069] To sum up, the introduction of the limiting mechanism not only provides flexibility in adjusting the angle of the drainage tube 17, but also ensures the stability of the drainage tube 17 after adjustment, avoids the decrease in drainage effect due to position change, and improves the convenience of operation of the device in actual application and the comfort of patient treatment.

[0070] In a further preferred embodiment of the present invention, an isolation portion 40 is provided in the drainage tube 17, and the cross-section of the isolation portion 40 is cross-shaped, dividing the interior of the drainage tube 17 into four channels, one of which is a drainage channel 42, and the remaining three channels are flushing channels 43; at the end of the drainage tube 17 inserted into the patient's body, the drainage channel 42 is in a closed state at this end, and flushing ports 41 are provided between the drainage channel 42 and the three flushing channels 43, and the flushing ports 41 are intermittently and evenly spaced, and the flushing channel 42 is the flushing tube 18.

[0071] In this embodiment, in order to optimize the efficiency of drainage and flushing and avoid cross contamination, an isolation portion 40 is cleverly provided inside the drainage tube 17, and its cross-section is a cross-shaped structure, which cleverly divides the internal space of the drainage tube 17 into four independent channels. Among them, one channel is designed as a drainage channel 42, which is specifically used to drain the liquid or secretions in the patient's body, and the remaining three channels are used as flushing channels 43, which are used to transport flushing fluid to the target area to achieve cleaning and disinfection of the drainage site. Even if one drainage channel 42 is blocked, the remaining drainage channels 42 can continue to drain, reducing the impact of the blockage on the drainage.

[0072] At the end of the drainage tube 17 inserted into the patient's body, the drainage channel 42 is in a closed state. This design ensures the unidirectionality of the drainage process, prevents external air or flushing liquid from flowing back into the patient's body, and ensures the safety of the operation. At the same time, a plurality of flushing ports 41 are provided between the flushing channel 43 and the drainage channel 42. These flushing ports 41 are arranged intermittently and at equal intervals, ensuring that the flushing liquid can be evenly distributed, effectively cleaning the entire drainage area and improving the flushing effect.

[0073] It is worth noting that the flushing channel 43 is actually the internal extension of the flushing tube 18, which not only provides a delivery path for the flushing liquid, but also realizes the precise injection of the flushing liquid through the design of the flushing port 41, further enhancing the pertinence and effect of the flushing. This innovative design not only simplifies the operation process and reduces the workload of medical staff, but also significantly improves the use effect of the device.

[0074] Second embodiment:

[0075] In this embodiment, another implementation method is provided for the arrangement of the drainage tube 17 and the flushing tube 18 in the first embodiment, such as Figure 13-14 As shown, the flushing tube 18 can also be located at the center of the drainage tube 17, and together with the isolation portion 40, divide the interior of the drainage tube 17 into four drainage channels 42. The interior of the flushing tube 18 is the flushing channel 43. Flushing ports 41 are also provided between the flushing tube 18 and the four drainage channels 43, and the flushing ports are provided intermittently and at equal intervals.

[0076] In this embodiment, in order to further improve the efficiency and safety of flushing and drainage, the flushing tube 18 is cleverly designed at the center of the drainage tube 17, and works together with the isolation portion 40 to divide the internal space of the drainage tube 17 into four independent drainage channels 42. This design allows the flushing tube 18 to not only be located at the center of the drainage tube 17, but also to be provided with multiple flushing ports 41 between the four drainage channels 42, which are intermittently and evenly spaced, ensuring that the flushing liquid can be uniformly and accurately sprayed from the center to the surroundings, achieving full coverage and effective cleaning of the drainage area.

[0077] The flushing channel 43 is located inside the flushing tube 18, which not only provides a direct delivery path for the flushing liquid, but also realizes multi-directional injection of the flushing liquid through the design of the flushing port 41 between the four drainage channels 42, thereby enhancing the pertinence and effect of the flushing. This innovative internal structure design not only optimizes the flushing and drainage process, improves the convenience and efficiency of operation, but also ensures the uniform distribution of the flushing liquid, effectively avoids flushing dead corners, reduces the risk of cross infection, and provides patients with a more accurate, efficient, and safe treatment experience.

[0078] In summary, this embodiment places the flushing tube 18 at the center of the drainage tube 17 and cooperates with the isolation part 40 to not only achieve precise control and uniform distribution of the flushing liquid, but also improve the efficiency of flushing and drainage, and provides another solution to the problem of easy clogging of traditional drainage tubes.

[0079] It is worth noting that the circuits, electronic components and modules involved in the present invention are all prior art, and those skilled in the art can fully implement them. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0080] In summary, compared with the related art, the present device realizes precise control and efficient delivery of flushing liquid while using negative pressure drainage by setting up the coordinated use of the linkage mechanism and the negative pressure mechanism, ensures the stability of flow and pressure during the flushing process, and improves the flushing effect and safety;

[0081] By optimizing the multi-channel drainage tube 17 and providing a flushing tube 18, the influence of the blockage of the drainage tube 17 on the drainage is greatly reduced. At the same time, the drainage tube 17 can be flushed to solve the problem of drainage tube blockage;

[0082] The introduction of the limiting mechanism not only provides flexible adjustment of the angle of the drainage tube 17, but also ensures its stability after adjustment, avoids the reduction of drainage effect due to position change, and improves the convenience of operation of the device in practical application and the comfort of patient treatment;

[0083] By adding a filtering and sterilizing mechanism, the present invention effectively controls the spread of bacteria and viruses in the medical environment, improves the biosafety protection capability of the device, and provides safer and cleaner work for medical staff and patients.
