Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of medical device technology, and more specifically to an automated control system for a fluid collection box. Background Technology

[0002] When treating ophthalmic tissues, the flow rate of phacoemulsification and vitrectomy fluid needs to be controlled through the coordinated action of the effusion box and ophthalmic surgical equipment. However, the hot-melt welding process leads to problems such as poor sealing, dimensional instability, and insufficient weld strength. Therefore, a effusion box that can improve sealing reliability is needed. Currently, traditional effusion boxes rely on hot-melt welding to achieve sealing.

[0003] However, in practice, the following technical problems often arise when using a effusion collection box: Traditional fluid collection boxes typically employ simple planar seals, resulting in gaps or uneven compression at the sealing interface. This can lead to fluid leakage during long-term use or under pressure fluctuations, contaminating the equipment or affecting surgical safety. Furthermore, the traditional adhesive bonding method results in low assembly efficiency and stress concentration at connection points, causing structural loosening or seal failure, further exacerbating the risk of leakage.

[0019] The above-described embodiments of this disclosure have the following beneficial effects: Through an automated control system for a effusion box according to some embodiments of this disclosure, the effusion box can prevent liquid leakage during long-term use or pressure fluctuations, thereby improving the sealing performance of the effusion box; improving the assembly efficiency of the effusion box, reducing stress at connection points, and thus reducing structural loosening and the risk of leakage. Specifically, the reasons for the numerous technical problems of existing effusion boxes are as follows: the sealing design of traditional effusion boxes usually adopts a simple planar seal, resulting in gaps or uneven compression at the sealing interface, which easily leads to liquid leakage under long-term use or pressure fluctuations, contaminating equipment or affecting surgical safety; the traditional connection method is adhesive fixation, resulting in low assembly efficiency and stress concentration at connection points, leading to structural loosening or seal failure, further exacerbating the risk of leakage. Based on this, an automated control system for a liquid collection box is characterized in that the automated control system includes a liquid collection box and a control device, wherein the liquid collection box includes a cover plate, a sealing element, and a valve plate, the cover plate includes a front plate, a middle plate, and a rear plate, and the sealing element includes a middle plate seal and a rear plate seal; after the cover plates form a preliminary seal by clamping the sealing element, they are assembled and fixed; the liquid collection box is also provided with a liquid storage chamber, which is divided into a front liquid storage chamber and a rear liquid storage chamber by a reflective partition, both of which are used to control the liquid discharge after inputting air pressure; the liquid collection box is fixed to the control device during operation; the inner side of the liquid collection box is also provided with a hydrophilic coating; the control device is configured to perform the following steps: responding Upon detecting the installation of the aforementioned liquid collection box, the system controls the initiation of gas injection, outputting gas pressure to the liquid collection box and then inputting it into the liquid bottle; in response to detecting the gas pressure input of the aforementioned gas injection into the liquid bottle, the system controls the initiation of liquid injection, filling the liquid bottle into the storage tank; in response to detecting a stop command for the aforementioned liquid injection, the system controls the cessation of liquid injection; in response to detecting the initiation of waste liquid suction, the system draws waste liquid into the negative pressure chamber of the aforementioned liquid collection box; in response to detecting that the liquid in the aforementioned negative pressure chamber has accumulated to the upper limit, the system discharges the waste liquid from the aforementioned negative pressure chamber into the liquid collection bag; in response to detecting that the aforementioned negative pressure chamber has stopped discharging waste liquid, the system controls the initiation of the aforementioned gas injection, controlling the gas pressure output to achieve the target state; in response to detecting the aforementioned target state, the system stops the aforementioned gas injection. Because seals are provided between the front plate and the middle plate, and between the rear plate and the middle plate, the liquid collection box can prevent liquid leakage during long-term use or pressure fluctuations, thereby improving the sealing performance of the liquid collection box. Because the connection between the cover plates is by assembly, the assembly efficiency of the liquid collection box can be improved, the stress at the connection points can be reduced, and the possibility of structural loosening can be reduced, thereby reducing the risk of leakage of the liquid collection box.

[0033] In some embodiments, the aforementioned fluid collection box includes a cover plate, a seal, and a valve plate. The cover plate includes a front plate, a middle plate, and a rear plate, and the seal includes a middle plate seal and a rear plate seal. The cover plate can form the main protective structure of the fluid collection box and accommodate the seal and valve plate. The front plate, middle plate, and rear plate can all be integrally molded sheet metal. The seal can seal the gap between the middle plate and the rear plate, blocking the connection between the cavity of the fluid collection box and the outside. The sealing plate can be made of medical-grade silicone. For example, the seal can be made of liquid silicone. The valve plate can control the flow path inside the fluid collection box, reducing backflow of fluid. The valve plate can be made of highly elastic medical-grade rubber. For example, the valve plate can be made of butyl rubber.

[0034] In some embodiments, after a preliminary seal is formed between the cover plates by clamping sealing elements, they are assembled and fixed. The preliminary seal can be achieved by clamping the front plate and the middle plate together after a sealing element is provided between them, or by clamping the middle plate and the rear plate together after a sealing element is provided between them. The assembly and fixing can be achieved by assembling and fixing the front plate 6 to one side of the middle plate 4, and assembling and fixing the other side of the middle plate 4 to the rear plate 2. For example, the assembly and fixing can be achieved by ultrasonic welding, with the weld lines of the ultrasonic welding located in the peripheral area of ​​the groove and the raised structure. The peripheral area can characterize the edge of the groove and the raised structure, providing a bearing area for welding. The weld lines can be integrally formed on the side where the front plate and the middle plate meet, and on the side where the middle plate and the rear plate meet. The weld lines of the front plate and the middle plate are located in the same position, and the weld lines of the rear plate and the middle plate are located in the same position.

[0035] In some embodiments, the aforementioned effusion box is further provided with a liquid storage chamber, which is divided into a front liquid storage chamber and a rear liquid storage chamber by a reflective partition. Both the front and rear liquid storage chambers are used to control the liquid discharge after inputting air pressure. The effusion box is fixed to the control device during operation. The liquid storage chamber can be integrally formed and installed within the effusion box. In practice, the effusion box is snap-fitted to the control device. The control device can be a component that supports the operation of the effusion box, provides air pressure and negative pressure power, integrates control and sensing modules, and is adapted for ophthalmic surgical operations. For example, the control device can be the main unit of an ophthalmic phacoemulsification machine. In use, the reflective partition functions as follows: when the reflective partition receives an external light source, it reflects the received external light source to the front and rear liquid storage chambers for monitoring by adjacent light source sensors on the two side panels. The type of external light source is not limited; for example, the external light source can be an LED light. The position and type of adjacent external light source sensors are not limited. The aforementioned reflective baffle can be installed into a pre-set slot inside the aforementioned liquid storage tank via an edge-clamping structure. It can be used to separate the front and rear liquid storage tanks and reduce the impact of sudden pressure changes on the stability of the liquid discharge. For example, the reflective baffle can be made of ABS plastic. The aforementioned control device can characterize ophthalmic surgical equipment. The aforementioned ophthalmic surgical equipment can be a vitrectomy-phacoemulsification machine. The aforementioned side plate can be a sheet material used to form the aforementioned front and rear liquid storage tanks.

[0036] In some embodiments, a hydrophilic coating is further provided on the inner side of the aforementioned fluid collection box. This hydrophilic coating can be sprayed onto the aforementioned cover plate and also serves to reduce the adhesion of liquid to the inner wall of the cover plate, thereby reducing tissue fragments and waste fluid residue. For example, the transparent sheet can be polycarbonate, and the hydrophilic coating can be polyethylene glycol. The aforementioned control device is configured to perform the following steps: The first step involves initiating gas perfusion in response to the detection of the aforementioned effusion box installation. Gas pressure is output to the effusion box and then supplied to the fluid bottle. The installation of the effusion box indicates that it is secured to the control device. The fluid bottle is a sterile storage and delivery system for ophthalmic surgical perfusion fluid, providing sterile storage for the fluid perfusion of the effusion box. For example, the fluid bottle can be a sterile saline storage bottle. Gas perfusion indicates that gas output from the control device enters the effusion box through a gas inlet and then flows into the eye through a gas outlet. Simultaneously, the gas output from the gas inlet assists in driving the fluid perfusion, ultimately providing stable gas support for surgical field exposure.

[0037] The second step involves initiating liquid filling in response to the detected gas pressure input to the liquid bottle, thereby filling the liquid bottle into the storage tank. This storage tank can be used to store fluids used in ophthalmic surgery. The liquid filling process is characterized by the control device outputting gas pressure through the gas inlet and outlet to compress an external bottle and input liquid into the collection box.

[0038] Third, in response to the detection of a stop command to halt the liquid injection, the liquid injection is stopped. This stop command can be a shutdown signal generated by the control device to terminate the injection. For example, the shutdown signal could be a signal indicating that the gas injection pressure has exceeded the limit.

[0039] The fourth step involves, in response to the detection of waste fluid aspiration initiation, drawing the waste fluid into the negative pressure chamber of the aforementioned effusion box. This negative pressure chamber serves as a cavity providing negative pressure support for temporary storage during surgical aspiration. The waste fluid aspiration process involves the control device applying negative pressure through the negative pressure interface to draw fragments generated during intraocular surgery back into the temporary fluid storage chamber, then into the negative pressure chamber. When the fluid level reaches its upper limit, a peristaltic pump discharges the fragments through the fluid outlet into the effusion bag, thus completing the fragment removal process.

[0040] Fifth, in response to the detection that the liquid accumulation in the negative pressure chamber has reached the upper limit, the waste liquid in the negative pressure chamber is discharged into a collection bag. The upper limit can be used to determine whether the negative pressure chamber meets the conditions for waste liquid discharge. The collection bag can be used to collect the surgical waste liquid discharged from the negative pressure chamber.

[0041] The sixth step involves controlling the initiation of gas perfusion in response to the detection that the negative pressure chamber has stopped discharging waste liquid, and controlling the gas pressure output to achieve the target state. This target state can be characterized by the intraocular pressure being stably maintained within the surgical safety threshold range (e.g., 20-30 mmHg) after gas is output into the eye through gas outlet 13, resulting in a full and clear intraocular visual field.

[0042] Step 7: In response to the detection of the above target state, stop the above gas injection.

The dimensions of both the middle plate seal 5 and the rear plate seal 3 may be 0.3~0.5mm larger than the dimensions of the corresponding grooves. The protrusion and the groove may be integrally formed. It should be noted that the specific arrangement of the protrusion and the groove is not specifically limited and can be adjusted according to actual needs. The connection between the front plate 6 and the middle plate 4 may be a snap-fit ​​and fixed assembly. One side of the aforementioned middle plate 4 may be provided with a groove that matches the shape of a protrusion on one side of the aforementioned front plate 6. The protrusion of the aforementioned front plate 6 and the groove of the aforementioned middle plate 4 are clamped together to achieve a seal. The protrusion of the aforementioned front plate 6 and the groove of the aforementioned middle plate 4 are clamped together to form a sealing barrier. The assembly and fixation of the aforementioned front plate 6 and the aforementioned middle plate 4 can be characterized by using ultrasonic welding to fix the aforementioned front plate 6 and the aforementioned middle plate 4, so that the aforementioned front plate 6 and the aforementioned middle plate 4 are connected. The other side of the aforementioned middle plate 4 may be provided with a protrusion that matches the shape of a groove on one side of the aforementioned rear plate 2. The protrusion of the aforementioned middle plate 4 and the groove of the aforementioned rear plate 2 are clamped together to form a sealing barrier. The aforementioned rear plate sealing element 3 is embedded between the aforementioned middle plate 4 and the aforementioned rear plate 2. It should be noted that the connection method of the aforementioned middle plate 4 and the aforementioned rear plate 2 is not specifically limited here, and can be adjusted according to actual needs. For example, the connection between the middle plate 4 and the rear plate 2 can be achieved by first snapping the middle plate 4 and the rear plate 2 together, and then using ultrasonic welding to fix the middle plate 4 and the rear plate 2 together. For example, the dimensions can be the width and length of the seal. The shape of the middle plate seal 5 can be an annular structure adapted to the groove shape of the middle plate 4, and the shape of the rear plate seal 3 can be an annular structure adapted to the groove shapes of both the middle plate 4 and the rear plate 2. This annular structure can reduce liquid leakage inside the sump. The dimensions of both the middle plate seal 5 and the rear plate seal 3 are larger than the dimensions of their corresponding grooves to improve the sealing performance. This sealing barrier can reduce liquid or gas leakage from the sump.

[0044] Optionally, the weld lines on the connecting side of the front plate 6 and the middle plate 4, and on the connecting side of the middle plate 4 and the rear plate 2, can all be reinforcing ribs. The weld lines on the connecting side of the front plate 6 and the middle plate 4, and on the connecting side of the middle plate 4 and the rear plate 2, serve as reinforcing ribs to improve the stability and rigidity of the liquid collection box.

[0045] Optionally, after the protrusion of the front plate 6 engages with the groove of the middle plate 4, the gap between the front plate 6 and the middle plate 4 can be less than 0.1 mm. Similarly, after the protrusion of the middle plate 4 engages with the groove of the rear plate 2, the gap between the middle plate 4 and the rear plate 2 can be less than 0.1 mm. The gaps between the front plate 6 and the middle plate 4, and between the middle plate 4 and the rear plate 2, are both less than 0.1 mm to improve the sealing performance of the liquid collection box, enabling it to achieve long-term stable use.

[0051] In addressing the aforementioned technical problems in the process of adopting technical solutions, and considering the application scenario—vacuum collection boxes for elderly patients with fragile eye tissues—the following technical problem often arises: Traditional vacuum collection boxes rely solely on rudimentary control devices. Given the fragility of the elderly's eye tissues, pressure fluctuations within the negative pressure chamber cannot be promptly relieved, and there is no automatic protection mechanism when the negative pressure is too high. This results in the negative pressure being directly transmitted to the suction tubing, frequently causing injury to the patient's tissue cells. Furthermore, the traditional waste fluid flow channel lacks an anti-backflow design, causing backflow of waste fluid during the waste discharge process when the negative pressure drops sharply, contaminating the work area and potentially leading to infection. Additionally, the inner surface of the storage chamber may absorb residue, causing impurities carried by the perfusion fluid to accumulate on the tube walls, gradually narrowing or even blocking the flow channel, posing an infection risk to high-risk patients. To address the following requirements for this application scenario: precise negative pressure control, anti-backflow design, and reduced flow channel blockage, we have decided to adopt the following solution: Optionally, the inlet of the aforementioned phacoemulsification infusion channel can be larger than the inlet of the aforementioned vitreous curing infusion channel. The aforementioned negative pressure chamber can be equipped with a miniature pressure relief valve. The miniature pressure relief valve can be a diaphragm structure with a diaphragm thickness ranging from 0.1 to 0.15 mm. The opening pressure threshold of the miniature pressure relief valve can be in the range of -0.05 to -0.03 MPa. A dust cap can be provided on the outer side of the aforementioned miniature pressure relief valve. A snap-fit ​​flange can be provided on the inner side of the aforementioned dust cap, and a matching snap-fit ​​groove can be provided at the corresponding position on the aforementioned rear plate. The aforementioned dust cap and the aforementioned rear plate can be detachably connected via the snap-fit ​​flange and snap-fit ​​groove. A one-way anti-backflow valve can be embedded in the waste liquid channel between the aforementioned negative pressure chamber and the waste discharge connector. The inner surfaces of the aforementioned internal infusion channel and the aforementioned storage tank can be coated with a hydrophilic coating. The aforementioned hydrophilic coating can be cured onto the inner surfaces of the aforementioned internal infusion channel and the aforementioned storage tank using a UV curing process. The inlet of the aforementioned phacoemulsification infusion channel is larger than that of the aforementioned vitreous infusion channel, which can be used to meet the different demand requirements of the aforementioned phacoemulsification fluid and the aforementioned vitreous infusion fluid. The aforementioned miniature pressure relief valve can detect when the negative pressure value in the aforementioned negative pressure chamber exceeds the opening pressure threshold, and automatically rupture to release pressure, thereby reducing tissue damage caused by negative pressure. The thickness range of the aforementioned miniature pressure relief valve can balance structural strength and pressure relief reliability. The aforementioned opening pressure threshold can reduce the occurrence of the miniature pressure relief valve activation caused by the normal operating negative pressure in the aforementioned negative pressure chamber. The aforementioned dust cap and the aforementioned rear plate are detachably connected by a snap-fit, which can improve the integrity of the miniature pressure relief valve function and enhance the aseptic nature of the operation process. The aforementioned snap-fit ​​flange can be used to engage with the snap-fit ​​groove, limit the installation offset of the dust cap, and enhance the sealing of the connection. The aforementioned snap-fit ​​groove can be used to adapt and fasten with the snap-fit ​​flange, provide installation support for the dust cap, and enable quick installation and removal of the dust cap. The aforementioned corresponding positions can characterize the positions on the rear plate that match the size of the dust cap snap-fit ​​flange. The aforementioned one-way backflow prevention valve can reduce the occurrence of waste liquid backflow when discharging waste liquid into the aforementioned negative pressure chamber. For example, the snap-fit ​​flange can be an annular flange, the snap-fit ​​groove can be an annular groove, and the one-way backflow prevention valve can be a duckbill type one-way valve. The aforementioned hydrophilic coating design can reduce the adsorption of proteins and cells on the pipe wall, reduce the risk of flow channel blockage, and improve the flowability of the filling liquid. For example, the hydrophilic coating material can be a polyethylene glycol-based coating. The aforementioned waste discharge outlet is an interface located on the aforementioned front plate for discharging waste liquid.

[0052] The above optional embodiments, as an inventive point of this disclosure, solve the technical problem of "the inability to release pressure in time when the negative pressure fluctuates in the negative pressure chamber, the lack of an automatic protection mechanism when the negative pressure is too strong, resulting in the negative pressure being directly transmitted to the suction pipeline, causing injury to tissue cells; causing the waste liquid to flow back in reverse when the negative pressure drops suddenly during the waste discharge process, resulting in contamination of the working area and causing infection; and causing impurities carried by the perfusion fluid to be easily adsorbed and accumulated on the pipe wall, resulting in the flow channel gradually narrowing or even blocking." The specific factors that lead to the lack of a negative pressure self-protection mechanism in effusion boxes, resulting in liquid contamination and the risk of blockage are as follows: For effusion boxes used by elderly patients with fragile eye tissues, traditional effusion boxes rely solely on rudimentary control equipment. Given the fragility of the elderly's eye tissues, pressure fluctuations within the negative pressure chamber cannot be promptly relieved. Furthermore, the lack of an automatic protection mechanism when negative pressure is too high causes the negative pressure to be directly transmitted to the suction tubing, frequently resulting in tissue injury to the patient. Additionally, the traditional waste liquid flow channel lacks a backflow prevention design, causing waste liquid to flow back during the waste discharge process when negative pressure suddenly drops, contaminating the work area and potentially leading to infection. Finally, the inner surface of the storage chamber may absorb residue, causing impurities carried by the perfusion fluid to easily accumulate on the tube walls, leading to gradual narrowing or even blockage of the flow channel, posing a risk of infection to high-risk patients. If the above factors are addressed, the effusion box can possess a negative pressure self-protection mechanism, reducing the occurrence of liquid contamination and minimizing the risk of blockage. To achieve this effect, the effusion box for ophthalmic surgical equipment disclosed herein is equipped with a diaphragm-type micro-pressure relief valve to possess a negative pressure self-protection mechanism. When encountering abnormal negative pressure, it can automatically weaken the threat of abnormal air pressure. Because a one-way anti-backflow valve is provided, the situation of waste liquid backflow caused by a sudden drop in negative pressure and contamination of the working area is reduced, thus reducing the risk of infection. Furthermore, a hydrophilic coating is provided to reduce the adsorption and accumulation of impurities carried by the infusion fluid on the inner wall of the effusion box, thereby reducing the risk of blockage inside the effusion box and minimizing the risk of aspiration injury to the patient's tissue cells.

[0053] In addressing the second technical problem mentioned above, and considering the application scenario—the effusion box for elderly cataract patients at high risk of tissue fragility—the following third technical problem often arises: Because the lens nucleus of elderly cataract patients is often hardened, resulting in larger and more easily deposited fragments, and because traditional waste liquid internal channels lack filtration designs, lens fragments and vitreous fibers in the waste liquid directly enter the waste discharge component. This leads to residue accumulation that cannot be cleaned, causing contamination of the fragile eye tissues of elderly patients. Furthermore, because traditional infusion output connectors lack integrated pressure sensing modules, there is no real-time pressure monitoring; judgment relies solely on experience. This results in improper installation of the effusion box, failure to detect infusion fluid supply interruptions in a timely manner, and inaccurate pressure detection, causing irreversible damage to the fragile eye tissues of elderly patients. To meet the following requirements for this application scenario—adapting to the fragility of eye tissues, reducing residue clogging of the flow channel, and ensuring high pressure detection accuracy—we have decided to adopt the following solution: Optionally, a detachable filter assembly may be provided in the middle section of the aforementioned waste liquid internal flow channel. The filter assembly may include a nylon filter membrane and a support frame. The support frame can be connected to the inner wall of the aforementioned waste liquid internal flow channel via a rotating snap-fit. Pressure sensing chambers may be integrated into the drainage channels of both the aforementioned front and rear liquid storage tanks. A flexible sensing diaphragm may be provided in the pressure sensing chamber. The surface of the flexible sensing diaphragm may be provided with contrast color coding. When the aforementioned liquid collection box is installed on a control device, the flexible sensing diaphragm may be positioned on the side facing the optical sensor of the control device. A rigid support ring may be provided on the other side of the pressure sensing chamber. The rigid support ring may be positioned on the outer periphery of the deformation area of ​​the aforementioned flexible sensing diaphragm. The inner diameter of the rigid support ring may be adapted to the diameter of the deformation area of ​​the aforementioned flexible sensing diaphragm. The thickness of the rigid support ring may be in the range of 1~2 mm. The rigid support ring may be fixed to the base of the aforementioned pressure sensing chamber by assembly. The aforementioned filter assembly can intercept residues larger than 20 μm in diameter while allowing residues smaller than 20 μm to pass through, thus reducing the potential clogging caused by residues larger than 20 μm. The nylon filter membrane is nested within the support frame, which in turn supports the nylon filter membrane, allowing it to spread and shield against residues. The pressure sensing chamber may be equipped with contrast color coding, which displays different colors depending on the pressure received. When the liquid collection box is installed in the control device, the optical sensor can detect changes in the contrast color coding caused by the deformation of the flexible sensing diaphragm to monitor the pressure in the drainage channel. The drainage channel characterizes the flow path for discharging liquid from the front and rear liquid storage chambers. For example, a white contrast color code indicates that the optical sensor can detect a moderate pressure at the infusion output connector; a green contrast color code indicates a slightly high pressure; and a yellow contrast color code indicates an unstressed pressure. The rigid support ring can be made of medical-grade polycarbonate. This material enhances both rigidity and mechanical strength. The rigid support ring can support the flexible sensing diaphragm, and its thickness range improves support effectiveness and spatial adaptability. No specific limitations are placed on the thickness range of the rigid support ring or the connection method between it and the base; adjustments can be made according to actual needs. For example, ultrasonic welding can be used for assembly and fixation.

[0054] The above optional embodiments, as an inventive point of this disclosure, solve the technical problem of "causing lens fragments and vitreous fibers in the waste liquid to directly enter the waste discharge component, resulting in the accumulation of residue that cannot be cleaned and can only be replaced as a whole; causing the lack of real-time pressure monitoring, relying solely on experience to judge, resulting in the incomplete installation of the effusion box, the inability to detect the interruption of the infusion fluid supply in time, and inaccurate pressure detection, causing irreversible damage to elderly patients with fragile eyes". The specific factors leading to the inability to clean up accumulated debris in the effusion box, improper installation, failure to detect interruptions in the infusion fluid supply, and inaccurate pressure detection are as follows: For effusion boxes used in elderly cataract patients who are at high risk due to their fragile eye tissues, the lens nucleus in these patients is often hardened, resulting in larger and more easily deposited fragments. Furthermore, traditional waste fluid channels lack filtration designs, allowing lens fragments and vitreous fibers in the waste fluid to directly enter the waste discharge components. This leads to debris accumulation that cannot be cleaned, contaminating the fragile eye tissues of elderly patients. Additionally, the traditional infusion output connector lacks an integrated pressure sensing module, resulting in no real-time pressure monitoring and reliance on experience. This leads to improper installation of the effusion box, failure to detect interruptions in the infusion fluid supply, and inaccurate pressure detection, causing irreversible damage to the fragile eye tissues of elderly patients. If the above factors are addressed, the accumulation of residue in the effusion box can be reduced, the risk of improper installation and interruption of irrigation fluid supply going undetected can be reduced, and the risk of inaccurate pressure detection can be lowered. To achieve this effect, the effusion box of the ophthalmic surgical equipment disclosed herein is equipped with a removable filter component to reduce the accumulation of the aforementioned residue. Because it is equipped with a pressure sensing membrane with contrast color coding, the pressure state inside the effusion box can be detected, so as to facilitate the detection of proper installation of the effusion box, timely detection of interruption of irrigation fluid supply, and reduction of the risk of inaccurate pressure detection.

[0055] In addressing the technical problem three mentioned above, and considering the application scenario—the effusion box for elderly cataract patients with fragile tissues—the following technical problem four often arises: Traditional effusion boxes lack the function to detect blockages in waste fluid, making it difficult to detect blockages promptly. Furthermore, the inability to accurately identify the box's condition leads to delayed and high-risk misjudgment rates of pipe blockage detection, necessitating manual judgment and increasing the risk of over-cleaning of the elderly patient's fragile tissues. To meet the following requirements for this application scenario—reducing tissue blockage, assessing blockages, and protecting the fragile tissues of elderly patients—we have decided to adopt the following solution: Optionally, the aforementioned liquid collection box is also equipped with a turbidity sensor and an ultrasonic flow sensor. The turbidity sensor and ultrasonic flow sensor are communicatively connected to the aforementioned control device. It should be noted that the aforementioned communication connection may include, but is not limited to, 3G / 4G connections, WiFi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultrawideband) connections, and other currently known or future development communication methods. The aforementioned turbidity sensor may be a sensor based on the principle of light transmission. For example, the turbidity sensor may be a scattered light sensor. The aforementioned ultrasonic flow sensor may be a time-difference measurement sensor. For example, the ultrasonic flow sensor may be a Doppler ultrasonic flow sensor.

[0056] The aforementioned control device is further configured to perform the following steps: The first step involves receiving the waste liquid flow rate signal collected by the ultrasonic flow sensor and the waste liquid concentration signal collected by the turbidity sensor in response to the aforementioned control device initiating negative pressure suction. The negative pressure suction characterizes the waste liquid suction operation performed by the control device. The waste liquid flow rate signal characterizes the rate at which the waste liquid flows within the flow channel during suction. The waste liquid concentration signal characterizes the content of intraocular fragments in the waste liquid. For example, the waste liquid flow rate signal could be 10 mL / min, and the waste liquid concentration signal could be 80 NTU (Nephelometric Turbidity Unit).

[0057] The second step involves filtering and preprocessing the aforementioned waste liquid flow rate and concentration signals to remove abnormal fluctuations, resulting in preprocessed flow rate and concentration signals. This filtering and preprocessing represents the process of removing interference from the sensor-acquired signals using mean filtering. The abnormal fluctuations represent signals that deviate from the normal range of waste liquid flow and fragment content variation. For example, abnormal fluctuations could be a flow rate signal jumping from 10 mL / min to 45 mL / min within a preset time period and then falling back to 10 mL / min within the same time period, or a concentration signal jumping from 80 NTU to 250 NTU within a preset time period and then falling back to 80 NTU within the same time period. For example, the preset time period could be 1 second. The preprocessed flow rate signal represents the waste liquid flow rate signal after filtering and preprocessing. The preprocessed concentration signal represents the waste liquid concentration signal after filtering and preprocessing.

[0058] The third step involves generating the state characteristics of the liquid accumulation box based on the pre-processed flow rate and concentration signals. These state characteristics characterize the smoothness of flow in all channels within the liquid accumulation box. In practice, the control device can generate these state characteristics using a multi-parameter fusion algorithm based on the pre-processed flow rate and concentration signals. For example, the smoothness of flow could be 70%.

[0059] The fourth step is to determine the flow status of the effusion box based on the aforementioned characteristics. The flow status can represent the specific operational condition type corresponding to the characteristics (e.g., unobstructed, blocked, cleared, or abrupt change). The unobstructed state indicates a flow smoothness of 60%-90%, with no blockages or leaks in the effusion box's channels, allowing tissue fragments to drain smoothly with the waste fluid, ensuring the normal progress of ophthalmic surgery. The blocked state indicates a flow smoothness of 0%-30%, where the effusion box's channels are blocked by large tissue fragments and foreign bodies generated during intraocular cutting, hindering waste fluid flow and obscuring the surgical field, requiring anti-blockage procedures. The cleared state indicates a flow smoothness of 90%-100%, with almost no residual tissue fragments in the waste fluid, optimal channel flow, and the target intraocular tissue having been largely cut and aspirated, allowing the surgery to enter its final stage. The above-mentioned sudden change state can characterize a drastic change in the smoothness of flow that exceeds the normal fluctuation range within 1 second (such as the smoothness of flow dropping from 70% to below 20%, or the smoothness of flow rising from 30% to above 95%), which may be caused by sudden blockage, abnormal unblocking or surgical operation.

[0060] The fifth step involves generating control commands in response to the determination that the flow state is blocked, and controlling the suction pump of the aforementioned control device to perform anti-blocking operations. These control commands can characterize adjustments to the suction pump's operating parameters related to the blockage in the flow channel of the aforementioned liquid collection box, as well as control signals defining the intensity and safety boundaries of the anti-blocking operation. For example, the suction pump's operating parameters could be reverse rotation for 5 seconds. The anti-blocking operation can characterize controlling the suction pump to rotate in reverse via the aforementioned control commands to impact the accumulated debris within the flow channel, thereby breaking up particle aggregation. In practice, control commands can be generated using a parameter adaptive algorithm based on the aforementioned pre-processed flow rate signal and the aforementioned pre-processed concentration signal.

[0061] The first sub-execution step, in response to determining that the flow state after the suction pump performs the anti-clogging operation is in a cleared state, displays an anti-clogging operation success message. This anti-clogging operation success message indicates that the anti-clogging operation was successful. In practice, the control device can display this anti-clogging operation success message.

[0062] The second sub-execution step, in response to determining that the flow state of the suction pump after performing the anti-clogging operation is still blocked, involves performing the aforementioned anti-clogging operation again. It should be noted that the method for detecting the flow state of the suction pump after performing the anti-clogging operation is the same as the method for generating the state characteristics of the liquid collection box based on the aforementioned pre-processing flow rate signal and pre-processing concentration signal, and for determining the flow state of the liquid collection box based on the aforementioned state characteristics; therefore, it will not be described again.

[0063] Step 6: In response to determining that the aforementioned flow state is a cleaning state, control the aforementioned control device to generate a prompt message. This prompt message can represent a signal to the surgical operator indicating that tissue cleaning is complete and the surgery is to be stopped; for example, the prompt message can be indicated by a green indicator light on the control device.

[0064] Step seven: In response to determining that the aforementioned flow state is a sudden change, the control device is controlled to perform a safety protection operation. This safety protection operation can characterize measures taken by the control device to reduce damage to ocular tissues in response to sudden anomalies. For example, the safety protection operation could be shutting down the suction operation.

[0065] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "delayed and high misjudgment rate of pipeline blockage identification, relying solely on manual judgment, leading to the risk of over-cleaning of fragile tissues in elderly patients." Specific factors contributing to the delayed and high misjudgment rate of pipeline blockage identification, the lack of objective evidence regarding the degree of target tissue cleaning, and the reliance on manual judgment leading to the risk of tissue residue or over-cleaning are as follows: For effusion boxes used in elderly cataract patients, a high-risk group with fragile tissues, traditional effusion boxes lack the function of detecting whether waste fluid is blocked. This results in the inability to detect blockages in a timely manner and to accurately identify the state characteristics of the effusion box, leading to delayed and high misjudgment rate of pipeline blockage identification, relying solely on manual judgment, and thus the risk of over-cleaning of fragile tissues in elderly patients. To achieve this effect, the automated control system for effusion boxes in this disclosure is equipped with a turbidity sensor and an ultrasonic flow sensor to identify the blockage status of the effusion box, and then performs anti-blockage operations accordingly. If aspirated tissue is detected, the aspiration operation is immediately stopped.

[0066] The above-described embodiments of this disclosure have the following beneficial effects: Through an automated control system for a effusion box according to some embodiments of this disclosure, the effusion box can prevent liquid leakage during long-term use or pressure fluctuations, thereby improving the sealing performance of the effusion box; improving the assembly efficiency of the effusion box, reducing stress at connection points, and thus reducing structural loosening and the risk of leakage. Specifically, the reasons for the numerous technical problems of existing effusion boxes are as follows: the sealing design of traditional effusion boxes usually adopts a simple planar seal, resulting in gaps or uneven compression at the sealing interface, which easily leads to liquid leakage under long-term use or pressure fluctuations, contaminating equipment or affecting surgical safety; the traditional connection method is adhesive fixation, resulting in low assembly efficiency and stress concentration at connection points, leading to structural loosening or seal failure, further exacerbating the risk of leakage. Based on this, an automated control system for a liquid collection box is characterized in that the automated control system includes a liquid collection box and a control device, wherein the liquid collection box includes a cover plate, a sealing element, and a valve plate, the cover plate includes a front plate, a middle plate, and a rear plate, and the sealing element includes a middle plate seal and a rear plate seal; after the cover plates form a preliminary seal by clamping the sealing element, they are assembled and fixed; the liquid collection box is also provided with a liquid storage chamber, which is divided into a front liquid storage chamber and a rear liquid storage chamber by a reflective partition, both of which are used to control the liquid discharge after inputting air pressure; the liquid collection box is fixed to the control device during operation; the inner side of the liquid collection box is also provided with a hydrophilic coating; the control device is configured to perform the following steps: responding Upon detecting the installation of the aforementioned liquid collection box, the system controls the initiation of gas injection, outputting gas pressure to the liquid collection box and then inputting it into the liquid bottle; in response to detecting the gas pressure input of the aforementioned gas injection into the liquid bottle, the system controls the initiation of liquid injection, filling the liquid bottle into the storage tank; in response to detecting a stop command for the aforementioned liquid injection, the system controls the cessation of liquid injection; in response to detecting the initiation of waste liquid suction, the system draws waste liquid into the negative pressure chamber of the aforementioned liquid collection box; in response to detecting that the liquid in the aforementioned negative pressure chamber has accumulated to the upper limit, the system discharges the waste liquid from the aforementioned negative pressure chamber into the liquid collection bag; in response to detecting that the aforementioned negative pressure chamber has stopped discharging waste liquid, the system controls the initiation of the aforementioned gas injection, controlling the gas pressure output to achieve the target state; in response to detecting the aforementioned target state, the system stops the aforementioned gas injection. Because seals are provided between the front plate and the middle plate, and between the rear plate and the middle plate, the liquid collection box can prevent liquid leakage during long-term use or pressure fluctuations, thereby improving the sealing performance of the liquid collection box. Because the connection between the cover plates is by assembly, the assembly efficiency of the liquid collection box can be improved, the stress at the connection points can be reduced, and the possibility of structural loosening can be reduced, thereby reducing the risk of leakage of the liquid collection box.
