Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a portable device integrating dual-liquid irrigation and suction after surgery for multi-space infections in oral and maxillofacial surgery. Background Technology

[0002] Multi-space infections of the oral and maxillofacial region are common acute and severe conditions in oral and maxillofacial surgery, often requiring surgical incision and drainage. Postoperative dressing changes and irrigation of the surgical area are crucial aspects of treatment. This typically involves alternating use of saline and hydrogen peroxide to repeatedly irrigate the surgical area to clean the wound, disinfect, and promote granulation tissue growth.

[0003] Currently, in clinical practice, medical staff typically use syringes to draw saline and hydrogen peroxide separately, manually inject them into the wound to rinse it, and then use a separate suction device to aspirate the accumulated waste fluid after rinsing. This traditional method has the following shortcomings: 1. Repeatedly drawing up the irrigation fluid with a syringe and changing the syringe multiple times results in a long dressing change time, increasing the workload of medical staff; 2. The limited aspiration volume of a single syringe is insufficient to meet the needs of large-volume flushing, requiring repeated aspiration; 3. Physiological saline and hydrogen peroxide need to be used alternately, but the existing device cannot simultaneously load two large volumes of flushing fluid and switch between them conveniently; 4. Fluid tends to accumulate in the surgical area after rinsing, requiring the use of a suction device for aspiration, which disrupts the procedure and increases the risk of contamination.

[0004] Therefore, how to provide a portable device integrating dual-liquid irrigation and suction after multi-space infection surgery in oral and maxillofacial surgery has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address at least one technical problem in the prior art, this invention provides a portable dual-liquid irrigation and suction device for postoperative multi-space infection in oral and maxillofacial surgery. The liquid storage module, control module, and waste liquid collection module can be independently replaced, repaired, and upgraded. Different capacity liquid storage modules can be flexibly selected according to clinical scenarios to achieve multiple uses in one device. There is no liquid leakage during module replacement, ensuring a hygienic operating environment.

[0006] To achieve the above objectives, the present invention provides a portable dual-liquid irrigation and suction device after multi-space infection surgery in oral and maxillofacial surgery, comprising: a base, a housing, a liquid storage module, a control module, a waste liquid collection module, and an operating handle. The housing is installed on the top of the base, and the liquid storage module, the control module, and the waste liquid collection module are detachably connected from top to bottom inside the housing. The operating handle is connected to the liquid storage module and the waste liquid collection module respectively.

[0007] Furthermore, the liquid storage module includes a drawer, which is slidably mounted inside the box via a slide rail. The interior of the drawer is divided into two cavities by a partition, each containing a hydrogen peroxide storage container and a saline storage container. The hydrogen peroxide storage container and the saline storage container are connected to a main pipeline via branch lines. The main pipeline is connected to the liquid outlet channel inside the operating handle. The hydrogen peroxide storage container and the saline storage container are each equipped with a hydrogen peroxide suction pump and a saline suction pump, respectively, which are connected to two branch lines.

[0008] Furthermore, the control module includes a second drawer, which is slidably mounted inside the box via a slide rail. The second drawer contains a controller and a power module, and the power module is electrically connected to the controller.

[0009] Furthermore, the waste liquid collection module includes a third drawer, which is slidably mounted inside the box via a slide rail. A waste liquid collection tank is installed inside the third drawer. The waste liquid collection tank is connected to the liquid collection channel inside the operating handle via a waste liquid collection pipe. The liquid collection channel is located outside the liquid outlet channel. A waste liquid collection pump is installed inside the waste liquid collection tank, and the waste liquid collection pump is connected to the waste liquid collection pipe.

[0010] Furthermore, the outer end of the liquid collection channel is wrapped with a woven sheath.

[0011] Furthermore, a one-way valve is provided at the top opening of the waste liquid collection tank where it connects with the waste liquid collection pipeline, and a drain pipe is installed at the bottom with a drain valve installed on the drain pipe.

[0012] Furthermore, a detachable Y-type filter is installed at the connection point between the hydrogen peroxide storage container and the saline storage container.

[0013] Furthermore, a top cover is installed on the top of the box, a handle is installed on the top of the top cover, and a control panel is provided on the front of the top cover, which is electrically connected to the controller.

[0014] Furthermore, a groove is provided on one side of the box, and a pipe hook is installed in the groove.

[0015] Furthermore, adjustable feet are installed at the four corners of the bottom of the base.

[0016] The beneficial effects of this invention are as follows: 1. This invention integrates the delivery of rinsing fluid and the absorption of waste fluid into the same device and the same operating handle, so as to realize the simultaneous rinsing and suction. This solves the pain point of traditional methods where rinsing is done before suction and the operation is not continuous, significantly shortens the dressing change time, and reduces the workload of medical staff.

[0017] 2. The liquid storage module can simultaneously hold two large-capacity liquid storage containers, namely hydrogen peroxide and physiological saline. The two flushing solutions can be switched with one button through an independent suction pump, eliminating the need to repeatedly change syringes or tubing and greatly improving flushing efficiency.

[0018] 3. The liquid storage module, control module, and waste liquid collection module are independent of each other, and different capacity liquid storage modules can be flexibly selected according to clinical scenarios to achieve multiple uses of one machine; each module can be replaced, repaired and upgraded independently, reducing the total life cycle cost.

[0019] 4. No liquid leakage occurred during module replacement. The one-way valve design of the waste liquid collection box prevents backflow, ensuring a hygienic and safe operating environment.

[0020] 5. The portable design, including a handle, built-in power supply, and compact structure, makes the device suitable not only for operating rooms and wards, but also for emergency outpatient visits, primary care wards, and field medical scenarios, with broad clinical application prospects.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0028] refer to Figure 1 This invention provides a portable device integrating dual-liquid irrigation and suction after multi-space infection surgery in oral and maxillofacial surgery, comprising: a base 1, a housing 2, a liquid storage module 3, a control module 4, a waste liquid collection module 5, and an operating handle 6. The housing 2 is installed on the top of the base 1. The liquid storage module 3, the control module 4, and the waste liquid collection module 5 are detachably connected from top to bottom inside the housing 2. The operating handle 6 is connected to the liquid storage module 3 and the waste liquid collection module 5 respectively.

[0029] The liquid storage module 3, control module 4, and waste liquid collection module 5 are independent and detachable, allowing users to replace, repair, or upgrade individual modules according to clinical needs, significantly reducing usage costs and maintenance difficulty. The three modules are arranged vertically in a compact structure, reducing the overall footprint and facilitating flexible placement and movement in space-constrained environments such as operating rooms and wards. The integration of irrigation and suction functions into a single device solves the problems of separation between irrigation and suction and the need for frequent instrument changes in traditional operations, simplifying the operation process. Each module can be independently disassembled and assembled, facilitating transportation and portability, and providing feasible solutions for bedside operations, emergency outpatient visits, and field medical scenarios.

[0030] refer to Figure 2 The liquid storage module 3 includes a drawer 7, which is slidably mounted inside the housing 2 via a slide rail. The interior of the drawer 7 is divided into two cavities by a partition 8. The two cavities are respectively equipped with a hydrogen peroxide storage container 9 and a saline storage container 10. The hydrogen peroxide storage container 9 and the saline storage container 10 are respectively connected to the main pipeline via branch lines. The main pipeline is connected to the liquid outlet channel inside the operating handle 6. The hydrogen peroxide solution container and the saline storage container 10 are respectively equipped with a hydrogen peroxide suction pump and a saline suction pump, which are respectively connected to the two branch lines.

[0031] The drawer 7 is divided into two independent chambers by the partition 8, which can simultaneously hold both hydrogen peroxide and saline for irrigation. The ample capacity avoids the cumbersome operation of repeated aspiration with traditional syringes, meeting the clinical need for large-volume irrigation after surgery. The hydrogen peroxide and saline aspiration pumps operate independently, allowing for easy switching of irrigation solutions as needed during surgery. This one-button switching eliminates the need to replace any tubing or instruments, significantly reducing dressing change time. The drawer design makes loading, unloading, replacing, and cleaning the storage containers extremely convenient. Medical staff can easily pull out the drawer for operation, reducing operational difficulty. The independent storage containers, combined with the tubing connection method, effectively prevent liquid leakage during module replacement, ensuring a hygienic operating environment and the safety of medical staff.

[0032] To further optimize the technical solution, a miniature concentration sensor and a temperature sensor were added inside the hydrogen peroxide storage container 9 to monitor the effective concentration of hydrogen peroxide in real time. When the detected concentration is lower than the effective threshold, the system automatically prompts for replacement; when the temperature deviates from the optimal activity range, temperature compensation is performed through the constant temperature jacket surrounding the hydrogen peroxide storage container 9.

[0033] To address the gas-generating characteristics of hydrogen peroxide, a slow-release pulse irrigation mode was designed. This mode delivers hydrogen peroxide intermittently in short pulses (e.g., 0.5-1 second per pulse), with a 2-3 second interval between each pulse. This allows sufficient time for the generated gas to escape, preventing gas accumulation in deep spaces and thus avoiding pressure buildup. Based on the hydrogen peroxide decomposition rate and wound reactivity, the timing of alternating saline-hydrogen peroxide irrigation is intelligently optimized. First, saline is used to pre-irrigate and moisten the wound, diluting some secretions. Then, hydrogen peroxide is pulsed in place to exert its bactericidal effect. Finally, saline is used to rinse away decomposition products and foam, forming an intelligent pre-irrigation-sterilization-final irrigation mode.

[0034] refer to Figure 3 The control module 4 includes a second drawer 11, which is slidably mounted inside the housing 2 via a slide rail. Inside the second drawer 11 are a controller 12 and a power module 13, and the power module 13 is electrically connected to the controller 12.

[0035] The built-in power module 13 enables the device to operate without relying on an external power grid, enhancing its portability and adaptability to the field. The controller 12, as the core control unit, enables precise driving of the suction pump, waste liquid collection pump, and other actuators. The control module 4 is designed separately from the liquid storage module 3 and the waste liquid collection module 5, facilitating independent maintenance, software upgrades, or power supply replacement of the control system without affecting the normal use of other modules. The controller 12 works in conjunction with the control panel 18, facilitating parameter setting, maintenance, and power supply replacement of the controller 12.

[0036] refer to Figure 4 and Figure 5 The waste liquid collection module 5 includes a drawer 3 22, which is slidably mounted inside the housing 2 via a slide rail. A waste liquid collection tank 14 is installed inside the drawer 3 22. The waste liquid collection tank 14 is connected to the liquid collection channel inside the operating handle 6 via a waste liquid collection pipeline. The liquid collection channel is located outside the liquid outlet channel. A waste liquid collection pump is installed inside the waste liquid collection tank 14, and the waste liquid collection pump is connected to the waste liquid collection pipeline.

[0037] The outflow and collection channels are integrated within the same operating handle 6, with the collection channel encasing the outflow channel. This coaxial sleeve structure enables simultaneous irrigation and suction. As the irrigation fluid reaches the wound through the inner tube, waste fluid is immediately aspirated through the outer tube, resolving the issue of fluid accumulation after irrigation requiring separate suction in traditional methods. The waste fluid collection pump operates continuously, removing waste fluid the instant the irrigation fluid reaches the wound, effectively preventing fluid accumulation in the surgical area, reducing the risk of infection, and maintaining a clear surgical field. The waste fluid collection pump provides active negative pressure suction, with collection efficiency far exceeding that of natural drainage, reducing the burden of manual operation for medical staff. The optimal suction negative pressure is automatically matched based on the current irrigation flow rate, ensuring that waste fluid is promptly removed without causing excessive negative pressure damage to the wound during the simultaneous irrigation and suction mode.

[0038] To further optimize the technical solution, the outer end of the liquid collection channel is wrapped with a braided sheath 15.

[0039] The braided sheath 15 enhances the wear resistance of the outer end of the collection channel and extends the service life of the operating handle 6; the braided structure improves the bending resistance while ensuring a certain degree of flexibility, preventing the pipeline from being compressed or broken during bending and ensuring smooth waste fluid suction; the wrapping layer can prevent metal or other hard materials from directly contacting the oral soft tissue, reducing the risk of mechanical damage to the wound and surrounding mucosa.

[0040] To further optimize the technical solution, a one-way valve is installed at the top opening of the waste liquid collection tank 14 where it connects with the waste liquid collection pipeline, and a drain pipe is installed at the bottom with a drain valve on the drain pipe.

[0041] The one-way valve ensures that waste liquid can only enter the waste liquid collection tank 14 through the collection pipeline and cannot flow back to the operating handle 6 or the pipeline, completely eliminating the risk of waste liquid backflow and contamination; the bottom drain pipe, together with the drain valve, allows medical staff to directly discharge waste liquid without disassembling the waste liquid collection tank 14, which is simple to operate and avoids secondary contamination caused by waste liquid splashing during the pouring process; the drain valve can be opened at any time to discharge waste liquid, so that the waste liquid collection tank 14 can be used continuously without interrupting the surgical operation due to the waste liquid being full.

[0042] To further optimize the technical solution, a detachable Y-type filter is installed at the connection point of the hydrogen peroxide storage container 9 and the physiological saline storage container 10.

[0043] The Y-type filter effectively filters particulate impurities (such as glass shards, rubber particles, etc.) in the irrigation fluid, preventing foreign objects from entering the surgical area with the irrigation fluid and ensuring patient safety. The detachable design of the filter facilitates regular cleaning or replacement of the filter element, avoiding blockage and bacterial growth caused by long-term use and ensuring the cleanliness of the irrigation fluid. While filtering impurities, it also protects the downstream pipeline and suction pump, reducing wear and blockage of the pump body and pipeline caused by particulate matter.

[0044] To further optimize the technical solution, a top cover 16 is installed on the top of the box 2, a handle 17 is installed on the top of the top cover 16, and a control panel 18 is provided on the front of the top cover 16. The control panel 18 is electrically connected to the controller 12.

[0045] The handle 17 allows medical staff to carry the device with one hand, enabling rapid transfer between the bedside, ward, and operating room, making it especially suitable for emergency outpatient visits and field medical scenarios. The control panel 18 provides an intuitive operating interface, allowing medical staff to switch the type of irrigation fluid, adjust the irrigation / suction flow rate, and start and stop the equipment via buttons or touch, making operation convenient and efficient. The control panel 18 is electrically connected to the controller 12, integrating all control functions on the top of the device, which conforms to ergonomic operating habits.

[0046] To further optimize the technical solution, a groove 19 is provided on one side of the box 2, and a pipe hook 20 is installed in the groove 19.

[0047] The operating handle 6 and its connecting tubing can be hung on the tubing hook 20 during breaks in use to prevent the tubing from dragging on the ground and causing contamination or tangling. The tubing hook 20 is embedded in the groove 19, which reduces the risk of damage caused by accidental collisions and makes the overall appearance of the machine neater. The tubing hook 20 is reasonably positioned so that medical staff can easily access and return the operating handle 6 at any time, improving work efficiency.

[0048] To further optimize the technical solution, adjustable support feet 21 are installed at the four corners of the bottom of the base 1.

[0049] The adjustable feet 21 can be adjusted in height according to the surface of the placement, ensuring that the device remains level and stable even on uneven surfaces and preventing tipping. The feet are equipped with anti-slip pads, which increase the friction between the device and the placement surface, while absorbing the micro-vibrations generated by the working parts such as the suction pump and reducing noise. The feet raise the base 1 a certain height off the placement surface, which is beneficial for heat dissipation and moisture prevention at the bottom and protects the internal electronic components.

[0050] The working process of this invention is as follows: (1) Pull out drawer one, put the storage containers containing hydrogen peroxide and saline into the two chambers respectively, connect the quick connectors between each branch and the main line, confirm that the Y-type filter is installed in place, push drawer one into the box and lock it.

[0051] Confirm that the one-way valve at the top of the waste liquid collection tank is working properly, the bottom drain valve is closed, and the waste liquid collection pipeline is securely connected to the collection channel of the operating handle.

[0052] Start the device by turning on the power switch on the control panel. The controller completes a self-test, and the power module supplies power to each suction pump and the controller.

[0053] (2) Medical staff hold the operating handle and align the outlet end of the fluid channel with the surgical wound. Select the required type of irrigation fluid through the control panel, and the controller drives the suction pump in the corresponding reservoir to start. Driven by the suction pump, the irrigation fluid is collected in the main pipeline through the branch line, and then delivered to the wound through the fluid channel inside the operating handle to achieve targeted irrigation.

[0054] While the flushing fluid is being output, the waste fluid collection pump continues to operate, creating negative pressure within the collection channel. Under this negative pressure, the accumulated flushing waste fluid in the surgical area is drawn in through the outer end of the collection channel and flows along the waste fluid collection pipeline into the waste fluid collection tank. A one-way valve ensures that the waste fluid does not flow back into the collection tank, and a braided sheath protects the outer end of the collection channel from obstruction during bending operations.

[0055] When hydrogen peroxide needs to be used alternately, medical staff can simply switch to hydrogen peroxide mode with a single button on the control panel. The controller stops the saline aspiration pump and simultaneously starts the hydrogen peroxide aspiration pump, which then delivers the hydrogen peroxide to the wound through the same main pipeline and outlet channel. The switching process is instantaneous, requiring no replacement of tubing or handles, ensuring continuity of operation.

[0056] (3) When the control panel indicates that the waste liquid collection tank level is close to the upper limit, or after each dressing change operation, the medical staff should align the drain pipe with the designated waste liquid collection container. Open the drain valve, and the waste liquid will flow out through the drain pipe under gravity. After draining, close the drain valve, and the waste liquid collection tank will be ready for continued use.

[0057] (5) When a certain flushing fluid is used up or a storage container of a different capacity needs to be replaced, pull out drawer one, disconnect the quick-connect fitting, take out the old container, put in the new container and reconnect it. Because the pipeline joint is equipped with a leak-proof structure, there is no liquid leakage during the replacement process.

[0058] Pull out the waste liquid collection box for thorough cleaning and disinfection, or replace the disposable waste liquid collection bag.

[0059] Pull out drawer two to inspect the controller, upgrade the software, or replace the power module.

[0060] (6) After operation, hang the operating handle on the pipe hook on the side of the box and tidy up the pipes. The device can be easily lifted off the table and transported to the next location using the top handle. The adjustable feet of the base can be readjusted to ensure the device is placed stably after transport.

[0061] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
