Description

Eye treatment device Technical Field

[0001] The present invention relates to the field of eye treatment, in particular to an eye treatment device. Background Art

[0002] The incidence of eye diseases in China is increasing year by year, becoming one of the most common eye diseases. Keratoconjunctivitis sicca, also known as keratoconjunctivitis sicca, refers to a broad range of conditions characterized by abnormalities in tear quality or quantity, or abnormal tear dynamics leading to decreased tear film stability, accompanied by ocular discomfort or damage to ocular surface tissue. Patients typically experience dry eyes, foreign body sensation, burning sensation, photophobia, blurred vision, and visual fatigue.

[0003] For some eye diseases, especially acute eye inflammation (such as drug-induced eyelid contact dermatitis, acute sensitive conjunctivitis, allergic conjunctivitis, orbital cellulitis, acute dacryocystitis, episcleritis, closed eye trauma, aqueous deficiency eye, etc.), cold compress can be used for treatment. For other eye diseases, such as chronic inflammation and pain, chalazion, chronic blepharitis, Demodex blepharitis, iridocyclitis, eye fatigue, eye syndrome, etc., hot compress can be used for treatment.

[0004] However, current methods of applying cold or hot compresses typically require multiple instruments, and precise temperature control is difficult. Existing eye compresses place temperature control / detection components near the eye, posing significant risks and high costs. Therefore, an eye compress device that overcomes these limitations is needed.

[0005] Summary of the Invention

[0006] In order to overcome the above technical defects, the purpose of the present invention is to provide an eye treatment device, which aims to solve the problems of the existing inability to integrate cold or hot compresses for the eyes, difficulty in accurately controlling the temperature, high risks of use, and high costs.

[0007] The present invention discloses an eye treatment device, comprising:

[0008] an eyelid actuator comprising a first surface, the first surface being positioned inside the patient's inner eyelid when in use, the eyelid actuator having a cavity defined therein, the first surface engaging the cavity;

[0010] a liquid inlet pipe connecting the liquid storage area and the eyelid actuator so that the second liquid is transported from the liquid storage area to the cavity;

[0011] a liquid outlet tube, connected to the eyelid actuator, so that the second liquid flows out of the cavity;

[0012] a temperature action device connected to the circulation pipeline to heat or cool the first liquid passing through the circulation pipeline;

[0013] Temperature control device, used to control temperature, the temperature control device includes

[0014] a first sensor, configured to obtain a first temperature inside the liquid storage portion;

[0015] a second sensor for acquiring a second temperature of the second liquid after passing through the cavity;

[0016] a control submodule, configured to control a second liquid flow rate and / or an operating parameter of the temperature action device according to the first temperature and the second temperature;

[0017] Based on the temperature control device, after the temperature action device heats or cools the first liquid, heat exchange is performed between the first liquid in the temperature control area and the second liquid in the liquid storage area. The second liquid enters the cavity in the eyelid actuator through the liquid inlet pipe and then flows out from the liquid outlet pipe to perform heat exchange with the first surface.

[0018] Preferably, a peristaltic pump is further included, connected to the liquid inlet tube, to control the flow rate of the second liquid entering the cavity.

[0019] Preferably, the liquid outlet pipe is connected to a negative pressure device, and the second liquid is extracted from the cavity through the negative pressure device.

[0020] Preferably, it further comprises a circulation pipeline connected to the temperature control zone, so that the first liquid enters and exits the temperature control zone through the circulation pipeline.

[0021] Preferably, the temperature control device further includes:

[0022] The third sensor is arranged on the temperature action device to obtain a third temperature and feed it back to the control submodule to adjust the second liquid flow rate and / or the operating parameters of the temperature action device.

[0023] Preferably, the temperature control device further comprises at least one fourth sensor for collecting the ambient temperature and feeding it back to the control submodule to adjust the second liquid flow rate and / or the operating parameters of the temperature action device.

[0024] Preferably, a blocking sensor extending to the temperature control zone is also provided on the liquid storage part. When it is monitored that the temperature of the first liquid in the temperature control zone exceeds a first threshold, the flow of the second liquid and / or the operation of the temperature action device are automatically interrupted.

[0025] Preferably, the temperature of the first surface is collected under different ambient temperatures, different flow rates, and different liquid storage temperatures, and then a fluid dynamics model is used to establish a thermodynamic model at each point in the second liquid flow path, and the established thermodynamic model is used to calculate the temperature of the first surface under different conditions.

[0026] Preferably, a protection sensor is connected to the temperature action device, and when it is detected that the temperature on the temperature action device exceeds a second threshold, the operation of the temperature action device is automatically interrupted.

[0027] Preferably, the eyelid actuator is detachably connected to the liquid storage part through the liquid inlet tube.

[0028] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0029] The dry eye treatment device provided by the present invention utilizes a temperature control device to control a temperature action device to heat / cool the first liquid passing through a circulation pipe. The first liquid enters the temperature control zone in the liquid storage part, and heats / cools the second liquid located in the liquid storage area through heat transfer in the liquid storage part. The second liquid enters the cavity from the liquid storage area through the liquid inlet pipe, and performs a hot / cold compress on the patient's eyelid through the first surface. The second liquid that has acted on the first surface then flows out through the liquid outlet pipe to form a circulation path. Based on the multi-stage heat transfer method, the temperature control device is used to achieve multi-stage precise temperature control on the patient's eyelid, realizing the integration of cold and hot compresses. The temperature action device can be arranged at a certain distance from the patient's eyes to solve the problem of high risk of using cold or hot compresses on the eyes. Existing hot compress devices have a heating device arranged on the treatment head, which not only poses an electromagnetic hazard to the eyes, but also may cause the risk of the treatment head exceeding a safe temperature. In particular, the temperature of the heating device itself must exceed the safe quality temperature when working. Once there is a problem with temperature control or heat insulation, the treatment head may cause the risk of overheating and burning the patient's sensitive and fragile eyes. The present invention uses multi-stage heat conduction involving liquid. The water flowing through the eyelid actuator is constant temperature water that has completed temperature control. It can be stably controlled within a safe temperature and there is no risk of overheating. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment: This embodiment discloses an eye treatment compress device. Figure 1 is a schematic structural diagram of an embodiment of the eye treatment compress device according to the present invention. As shown in Figure 1 , the eye treatment compress device includes an eyelid actuator 1, a liquid reservoir 5, a liquid inlet pipe 11, a liquid outlet pipe 12, a circulation pipe 15, a temperature control device 3, and a temperature control device 4. The solid lines in Figure 1 represent various pipes, such as the liquid inlet pipe 11, the liquid outlet pipe 12, and the circulation pipe 15, while the dashed lines indicate the temperature detection relationship between the temperature control device 4 and various components. The following describes the various structural components of the eye treatment compress device in detail.

[0045] Referring to Figures 1, 2, and 3, the eyelid actuator 1 is typically used in sets of two, acting on the left and right eyes respectively. Each eyelid actuator 1 includes a first surface 101 and a second surface 102. The first surface 101 is positioned on the inner side (i.e., inner eyelid) of the patient's upper eyelid 221 and lower eyelid 222 during use, and the second surface 102 faces the patient's eyeball 21. A cavity 103 is provided inside the eyelid actuator 1. The first surface 101 engages with the cavity 103 so that after a preset temperature (cold / hot) liquid is injected into the cavity 103, heat is transferred to the inner eyelid of the patient's eye through the first surface 101. It should be noted that Figures 2 and 3 are only one structural style of the eyelid actuator in this embodiment. Other styles may also be used in other embodiments, such as an eyelid actuator structure with separate upper and lower eyelids, an eyelid actuator that only acts on the inner side of the upper eyelid, etc. Regardless of the style used, the eyelid actuator must include a first surface that acts on the inner side of the inner eyelid and a cavity that engages with the first surface.

[0046] In the present invention, the cavity 103 is not connected to the first surface 101, that is, when the eye treatment device is in use, the second liquid entering the cavity 103 is confined in the cavity 103 and does not enter or exit the first surface 101 or the patient's eyelid.

[0047] In addition, the eyelid actuator 1 can be made of a hard material. In some embodiments, the eyelid actuator can also be made of a flexible material, thereby improving the comfort of the patient when the eye is placed in the eye.

[0048] Referring to Figures 1, 4, and 5, the liquid reservoir 5 is provided with a liquid storage area 501 and a temperature control area 502 that are not interconnected. A first liquid is stored and circulated in the temperature control area 502, while a second liquid is stored and circulated in the liquid storage area 501. The first and second liquids do not circulate with each other, but heat exchange occurs between them. Within the liquid reservoir 5, the liquid storage area 501 and the temperature control area 502 can be a structure that surrounds each other, or they can be independent of each other but have a heat transfer interface. The first and second liquids can be the same liquid, for example, both are medical liquids that can act on the inside of the eyelid (including but not limited to a predetermined type of therapeutic liquid or purified water that reaches a predetermined purity). Alternatively, the first and second liquids can be two different liquids. It should be noted that the second liquid in the liquid storage area 501 will enter the cavity 103 through the liquid inlet tube. Although the second liquid does not enter or exit the eyelid, in this embodiment, to ensure hygiene and safety and prevent accidental leakage that may cause eye contamination, the second liquid is preferably a medical liquid that can act on the inside of the eyelid as described above. Since the first liquid in temperature control zone 502 only needs to exchange heat with the second liquid, and liquid storage zone 501 and temperature control zone 502 are not connected to each other, the first liquid can be any liquid, preferably a liquid with a low specific heat capacity to improve temperature control efficiency. In some embodiments, considering safety issues during use and preventing hardware damage during use that may cause the first liquid to overflow into cavity 103, a configuration is adopted in which the first liquid and the second liquid are configured as medical liquids.

[0049] As a preferred example, the liquid storage area 501 can also be arranged into a structure surrounding the pipeline. Specifically, the temperature control area 502 is a cavity for storing liquid, and the liquid storage area 501 is integrated into the cavity structure of the temperature control area 502 in a structure surrounding the pipeline. The liquid storage area 501 can be any one of the pipeline structures of staggered arrangement, staggered surrounding arrangement (as shown in Figure 5), mesh structure arrangement or multi-layer U-shaped or round-shaped surrounding structure arrangement, wherein the second liquid enters the pipeline, the temperature control area 502 is filled with the first liquid, and the first liquid wraps the staggered distributed pipeline, so that the pipeline is completely immersed in the first liquid, so that the temperature of the first liquid is transferred to the second liquid through the pipeline shell.

[0050] Referring to Figure 1 , the liquid inlet tube 11 connects the liquid reservoir 501 with the eyelid actuator 1, allowing the second liquid to be transported from the liquid reservoir 501 into the cavity 103. The liquid outlet tube 12 communicates with the eyelid actuator 1, allowing the second liquid to flow out of the cavity 103. The liquid outlet tube 12, in conjunction with the liquid inlet tube 11, forms a path for the liquid to flow from the liquid reservoir 501 into the cavity 103 and then out. Through this path, the second liquid conducts heat to the first surface 101, which is in contact with the cavity 103, thereby providing a cooling or heating compress to the eyelids.

[0051] The liquid inlet pipe 11 and the liquid outlet pipe 12 are respectively sealed at one end with the liquid inlet pipe connection port 111 and the liquid outlet pipe connection port 112 of the eyelid actuator. The sealing connection method can be selected according to needs. For example, the liquid inlet pipe 11 and the liquid outlet pipe 12 can be integrally formed with the eyelid actuator 1 to ensure the sealing of the connection.

[0052] The other end of the liquid inlet tube 11 is connected to the liquid storage part 5. In a preferred embodiment, the eyelid actuator 1 is detachably connected to the liquid storage part 5 via the liquid inlet tube 11, so that the eyelid actuator 1 becomes a disposable replaceable component, ensuring hygiene and safety and avoiding cross infection of the eyes. Specifically, as an example, as shown in FIG4 , an integrated panel 6 is provided in the liquid storage part 6, and a first connection port 61 and a second connection port 62 for connecting to the ends of the liquid inlet tube 11 and the liquid outlet tube 12, respectively, are provided on the integrated panel 6. The first connection port 61 connected to the liquid inlet tube 11 is connected to the liquid storage area 501, and the second connection port connected to the liquid outlet tube 12 can be connected to a container for storing waste liquid.

[0053] In this embodiment, preferably, a peristaltic pump 13 is further included, which is connected to the liquid inlet pipe 11 to control the flow rate of the second liquid entering the cavity 103, so as to further control the flow rate and flow of the second liquid entering the cavity 103, and further control the temperature of the second liquid entering the cavity 103. When the peristaltic pump 13 is controlled to accelerate, the flow rate of the second liquid is relatively large, and more heat is transferred to the first surface 101, so that the temperature is slightly higher at this time. When the peristaltic pump 13 is controlled to decelerate, the flow rate of the second liquid is relatively small. Since the second liquid will generate some heat loss during the process of entering the cavity 103, the temperature of the first surface 101 is slightly lower at this time. Other existing devices that can achieve quantitative flow control can also replace the peristaltic pump 13.

[0054] The above-mentioned liquid outlet pipe 12 is used to allow the second liquid to flow out from the cavity 103. In a preferred embodiment, in order to control the flow state of the liquid, the other end of the liquid outlet pipe 12 is connected to a negative pressure device 14, that is, the negative pressure device 14 can be a container for accumulating waste liquid. Liquid is extracted from the cavity 103 by the negative pressure device 14, thereby controlling the second liquid with a certain temperature to stably / pass through the cavity 103 at a preset flow rate and perform heat exchange with the first surface 101. The negative pressure device 14 is used to extract the second liquid, and the extracted liquid can be collected so that it can be discharged outwards independently, forming an independent liquid circulation path for hot compress / cold compress. By adjusting the working parameters of the negative pressure device 14, the flow rate of the second liquid entering the negative pressure device 14 after being extracted can be effectively controlled. In conjunction with a flow rate control device such as a peristaltic pump 13 / power pump connected to the liquid inlet pipe 11, the liquid flows evenly at a preset flow rate in the liquid inlet pipe 11 and the liquid outlet pipe 12 and is discharged to the negative pressure container. Compared to solutions that only incorporate a peristaltic pump 13 or a power pump, for example, a flow control device, the simultaneous provision of a negative pressure device can smooth out the liquid flow rate, making temperature control easier and preventing significant temperature fluctuations. In particular, for applications where the inlet pipe 11 or outlet pipe 12 is long or has a small inner diameter, the negative pressure device 14 can ensure consistent and stable flow rates at all locations, even in very thin pipes. If manufacturing errors in the inlet pipe 11, outlet pipe 12, and / or eyelid actuator 1 result in inconsistent liquid resistance, the negative pressure device 14 can help overcome these issues and effectively improve stability.

[0055] The circulation pipeline 15 is in communication with the temperature control zone 502 , so that the first liquid enters and exits the temperature control zone 502 through the circulation pipeline.

[0056] The temperature action device 3 is connected to the circulation pipe 15 and heats or cools the first liquid passing through the circulation pipe 15. Specifically, the temperature action device 3 is arranged at a certain position in the circulation pipe 15. The first liquid in the temperature control zone 502 flows into the circulation pipe 15, passes through the temperature action device 3, is heated or cooled, and then re-enters the temperature control zone 502.

[0057] It should be noted that the circulation pipe 15 is important in the present invention. By setting up the circulation pipe, the first liquid can be recycled, saving costs. Compared with the technical solution of directly setting the temperature action device in the temperature control zone 502, it is difficult to perform cooling by direct setting, and therefore the cooling and heating devices need to be separated. The method of setting up the circulation pipe can simplify the temperature action device, making it possible to use a set of temperature action devices to achieve heating and cooling at the same time; direct setting will cause the temperature action device to occupy the volume of the liquid storage part, thereby making the overall volume of the liquid storage part too large, or causing the volume of the liquid storage area to be limited, affecting the heat conduction efficiency of the second liquid; in addition, the risk of liquid conductivity is also reduced by the circulation pipe. The use of the circulation pipe 15 is more conducive to precise temperature control, making the temperature change convergent and controllable, and the temperature can be finely adjusted each time, with an accuracy of +-0.1°C.

[0058] Specifically, in this embodiment, the aforementioned temperature action device 3 includes, but is not limited to, cooling / heating elements such as semiconductor chips. As an example, this embodiment further includes a heat dissipation module connected to one side of the semiconductor chip, enabling the semiconductor chip to operate in cooling mode and cool the first liquid. By changing the direction of the current, the direction of heat flow in the semiconductor chip can be altered, enabling the chip to achieve cooling or heating functions without requiring replacement of other components, thereby enabling a wider temperature control range. The heat dissipation module may include, but is not limited to, components such as a fan.

[0059] As can be seen from the above description, the present invention adopts a multi-stage temperature conduction method, that is, the first liquid is cooled / heated through the temperature action device 3 and the circulation pipe 15, and then the first liquid exchanges heat with the second liquid in the liquid storage part 5 in a non-contact manner. The second liquid then enters the cavity 103 through the liquid inlet pipe 11 to conduct heat conduction with the first surface 101, and the first surface 101 acts on the patient's inner eyelid.

[0060] Multi-stage temperature control is achieved through heat transfer. At this time, the temperature action device 3 can be arranged at a certain distance from the patient's eyelid. Different from the existing form of setting a heating element on the liquid inlet pipe or the eyelid actuator and setting the temperature adjustment / detection element near the eye, it effectively avoids the risk of electromagnetic waves to the sensitive and fragile eyes when the electrical components near the eyes are used.

[0061] At the same time, it can avoid large temperature fluctuations of the heating plate, which may cause the risk of exceeding the safe temperature, and the problem that direct heating cannot accurately control the temperature of the first surface.

[0062] Furthermore, the components of the eyelid actuator are greatly simplified, enabling one-time replacement of the eyelid actuator while significantly reducing costs. The present invention utilizes multi-stage heat conduction involving liquids, and the water flowing through the eyelid actuator is temperature-controlled and can be stably maintained within a safe temperature range, eliminating the risk of overheating.

[0063] By heat transfer, hot compress and cold compress can be simultaneously achieved on one device. For example, the operating temperature of hot compress can be 37 degrees Celsius to 45 degrees Celsius, and the operating temperature of cold compress can be 0 degrees Celsius to 20 degrees Celsius. The present invention is not limited to this.

[0064] Compared to directly heating / cooling the second liquid, this method of cooling / heating the first liquid through the temperature action device 3 and the circulation conduit 15 and then non-contactingly exchanging heat with the second liquid in the liquid reservoir 5 helps ensure liquid safety and hygiene, minimizing the risks of eye treatment caused by liquid leakage. Furthermore, this two-stage liquid heat conduction method ensures uniform heating of the second liquid, maintaining a stable temperature, avoiding large fluctuations, and making temperature control easier, thereby improving temperature control accuracy and patient experience during treatment of sensitive eye areas.

[0065] Since the present invention adopts a multi-stage temperature conduction method, it has very high requirements for temperature control.

[0066] Temperature control device 4 is used to control the temperature. This temperature control device 4 can accurately control the first liquid and the second liquid, thereby controlling the temperature of the first surface 101 applied to the patient's inner eyelid. In this embodiment, after the temperature action device 3 heats or cools the first liquid using temperature control device 4, heat exchange occurs between the first liquid in the temperature control area 502 and the second liquid in the liquid storage area 501. The second liquid enters the cavity 103 within the eyelid action device 1 through the liquid inlet pipe 11 and then flows out of the liquid outlet pipe, exchanging heat with the first surface 101.

[0067] Specifically, in this embodiment, the temperature control device 4 is used to achieve accurate temperature control. The temperature control device 4 includes:

[0068] First sensor 41 is used to obtain a first temperature of the second liquid or within liquid reservoir 5 before entering the liquid inlet pipe. First sensor 41 is disposed on liquid reservoir 5 to detect the temperature therein, i.e., the first temperature. This first temperature is the temperature of the first liquid, and due to heat exchange, this first temperature also represents the temperature of the second liquid, i.e., the temperature of the second liquid before entering cavity 103.

[0069] The second sensor 42 is used to obtain a second temperature of the second liquid after passing through the liquid outlet tube 12. The second sensor 42 can be placed at the rear end of the liquid outlet tube 12 (e.g., in front of a container for storing waste liquid) to obtain real-time temperature of the second liquid after passing through the cavity 103. Based on this second temperature and the first liquid temperature, heat loss after passing through the patient's eyelids can be determined.

[0070] It should be noted that, in this embodiment, the first sensor 41 and the second sensor 42 are preferably not arranged on the liquid outlet pipe 12 or the liquid inlet pipe 11, let alone on the eyelid actuator 1. This can keep the electronic components away from the eyes to avoid the risk of eye damage. On the other hand, it can achieve a one-time replacement of the eyelid actuator and the liquid outlet pipe and liquid inlet pipe while greatly reducing costs.

[0071] The control submodule 43 is used to control the second liquid flow rate and / or the working parameters of the temperature action device 3 according to the first temperature and the second temperature. As described above, the second liquid enters the cavity 103 and transfers heat to the first surface 101 to perform a hot compress / cold compress on the inner side of the patient's inner eyelid, that is, the temperature action device 3 is precisely controlled to heat / cool the first liquid to a preset temperature, and the temperature of the second liquid that enters the cavity 103 and generates heat transfer with the first surface 101 is further adjusted by controlling the second liquid flow rate.

[0072] In an optional embodiment, the temperature control device 4 described above may further include:

[0073] The third sensor 31 is arranged on the temperature action device 3 to obtain the third temperature and feed it back to the control submodule 43 to adjust the second liquid flow rate and / or the working parameters of the temperature action device. The above-mentioned third sensor 31 is arranged on the temperature action device to obtain the specific temperature of the temperature action device, thereby realizing accurate temperature control of the first liquid temperature.

[0074] In an optional embodiment, based on the above-mentioned temperature control device 4, it also includes at least one fourth sensor 44 for collecting ambient temperature and feeding it back to the control submodule 43 to adjust the second liquid flow rate and / or the working parameters of the temperature action device. As described above, in this embodiment, multi-stage temperature control is achieved by the temperature control device to determine the temperature of the second liquid entering the cavity 103 and reaching the patient's eyelid through the first surface 101. In this process, the ambient temperature will cause the second liquid to generate a certain amount of heat loss when entering the cavity 103 and during the heat transfer from the cavity 103 to the patient's eyelid. Therefore, the monitoring of the ambient temperature will affect the accuracy of temperature control. Based on this, the fourth sensor 44 is set so that the fourth sensor 44 collects the ambient temperature, so that the temperature loss caused by the environment is taken into account in the control submodule 43, and the second liquid flow rate (specifically, the working parameters of the peristaltic pump 13 can be adjusted) and / or the working parameters of the temperature action device 3, thereby improving the accuracy of temperature control.

[0075] The present invention utilizes temperature control device 4 to determine heat exchange between the first liquid and the second liquid, and between the second liquid and the first surface 101. This differs from the conventional method of installing temperature control device 3 on the eyelid actuator 1, which can create safety hazards. Because temperature control device 3 is located farther from the side of the eyelid actuator 1 where the first surface 101 contacts the patient's eyelid, the precise temperature value transferred from the second liquid to the first surface 101 can be calculated based on data collected by the various sensors in temperature control device 4.

[0076] This embodiment preferably calculates the temperature of the first surface 101 in real time by setting up a fluid dynamics model. In this embodiment, the temperature of the first surface 101 is collected at different ambient temperatures, different flow rates, and different constant temperature water tank (i.e., liquid reservoir) temperatures. The fluid dynamics model is then used to establish a thermodynamic model for each location along the second liquid flow path, thereby determining the temperature of the second liquid at each location in the device. Finally, the established model is used to calculate the temperature of the first surface 101 of the eyelid actuator 1 under different conditions. The specific steps include:

[0077] S1. Determine the fluid mechanics model: Select a fluid mechanics model suitable for the fluid type and problem. In this embodiment, the Navier-Stokes equation is exemplarily selected. This equation is one of the basic equations describing fluid motion and takes into account the velocity and pressure distribution of the fluid.

[0078] S2. Establish an energy equation: To model the temperature drop, an energy equation for the fluid must be established. This equation should include terms for convection, conduction, and possibly other energy loss mechanisms. For steady-state problems, the energy equation can be simplified to the Laplace equation.

[0079] S3. Setting Boundary Conditions: To solve the fluid dynamics and energy equations, appropriate boundary conditions must be specified. These conditions include the inlet fluid temperature, outlet fluid temperature, and a fixed temperature or heat flux at the boundary. In this example, the boundary conditions include varying the first temperature, second temperature, ambient temperature, and second liquid flow rate, as well as sampling the temperature of first surface 101 at varying first temperature, second temperature, ambient temperature, and second liquid flow rate.

[0080] S4. Numerical Solution: Discretize the established fluid dynamics model and energy equation and solve them using numerical methods. Commonly used methods include the finite element method, finite difference method, or finite volume method.

[0081] S5. Simulate temperature drop: The temperature drop process of the fluid in the entire area is simulated by numerical solution. Based on the simulation results, the temperature distribution of the fluid at different locations can be obtained.

[0082] S6. Analyze the results: Analyze the simulation results to identify the main mechanisms and influencing factors of the temperature drop. You can also modify the boundary conditions or model parameters to study the temperature loss under different circumstances.

[0083] In an alternative embodiment, a CFD fluid dynamics simulation program (including but not limited to Fluent, CFX, etc.) can be used to implement a solution for calculating the temperature of the first surface 101 in real time by setting a fluid dynamics model. Specifically, using one or more of the first temperature, second temperature, third temperature, ambient temperature, and second liquid flow rate, as well as the temperature of the first surface 101 collected under different conditions as boundary conditions, a thermodynamic model is established at each location in the second liquid flow path using the CFD fluid dynamics simulation program to obtain the temperature of the first liquid / second liquid at each location in the device. Finally, the established model is used to calculate the temperature of the first surface 101 of the eyelid actuator 1 under different conditions.

[0084] When using the eye treatment device of the present invention, the control submodule 43 dynamically adjusts the parameters of the temperature action device 3 according to the temperature of the first surface 101 calculated in real time by the model, and / or adjusts the flow rate of the second liquid through the peristaltic pump 13, thereby adjusting the temperature of the first surface 101 to the target temperature.

[0085] In other embodiments, the temperature of the first surface 101 can be simulated and calculated by setting an empirical model or a deep learning model, but by setting a fluid dynamics model to calculate the temperature of the first surface 101, real-time calculation and thus real-time adjustment can be achieved, and after repeated experiments, this method has high temperature control accuracy.

[0086] In order to further demonstrate the temperature control effect of the treatment device provided by this embodiment, the temperature of the second liquid located near the first surface determined by the above-mentioned eye treatment device is compared with the temperature (actual accurate value) measured by the temperature sensor arranged on the side of the liquid inlet tube near the eyelid actuator in real time. As shown in Figure 6, it can be seen that under multiple ambient temperatures, the temperature control provided by this embodiment is within plus or minus 0.5 of the actual accurate value, indicating that the temperature control of the eye treatment device provided by this embodiment is more accurate and safer.

[0087] In an optional embodiment, a blocking sensor 51 extending to the temperature control zone 502 is further provided on the liquid storage portion 5. When it is detected that the temperature of the first liquid in the temperature control zone 502 exceeds a first threshold value, the flow of the second liquid and / or the operation of the temperature action device are automatically interrupted. The blocking sensor 51 is provided to further reduce the risk during use. The blocking sensor 51 is arranged on the liquid storage portion 5 and partially extends to the temperature control zone 502. When an abnormality is detected in the temperature control zone 502, a stop operation is performed, i.e., the above-mentioned autonomous interruption of the flow of the second liquid and / or the operation of the temperature action device is reduced, thereby reducing the damage to the patient's eyes caused by the second liquid with abnormal temperature contacting the patient's eyelids. In a preferred embodiment, when the detection value of the blocking sensor 51 is abnormal, the peristaltic pump 13 is controlled to reverse, thereby accelerating the second liquid with abnormal temperature to move away from the eye.

[0088] In an optional embodiment, a protection sensor 32 is connected to the temperature application device 3. When the temperature of the temperature application device 3 exceeds a second threshold, the temperature application device 3 is automatically interrupted. In this embodiment, the protection sensor 32 is arranged on the semiconductor chip to detect the operating status of the semiconductor chip in real time to ensure that the semiconductor chip is operating normally after receiving the preset operating instructions. If the heating / cooling temperature of the semiconductor chip is abnormal, the protection sensor 32 is fed back to the control submodule 43 to prevent the temperature application device (semiconductor chip) from abnormally burning out during use of the therapeutic compress device, thereby improving the safety of the use process.

[0089] In this embodiment, the first liquid is heated / cooled by controlling the temperature action device 3 by the temperature control device 4 in the circulation pipe 15. The first liquid enters the temperature control area 502 in the liquid storage part 5 through the circulation pipe 15, and heats / cools the second liquid located in the liquid storage area 501 through heat transfer in the liquid storage part 5. The second liquid enters the cavity 103 from the liquid storage area 501 through the liquid inlet pipe 11, and performs hot / cold compress on the patient's eyelids through the first surface 101. Then, the second liquid that has acted on the first surface 101 flows out through the liquid outlet pipe 12 to form a circulation path.

[0090] In the embodiment provided by the present invention, based on the above, further, based on the temperature control device 4, a first sensor 41 is used to monitor the first temperature within the liquid reservoir to determine the temperature of the second liquid entering the liquid inlet pipe 11. A second sensor 42 arranged behind the liquid outlet pipe 12 is used to obtain the temperature of the second liquid after it acts on the first surface (the patient's eyelid) through the cavity 103. Based on this, the amount of heat transferred from the second liquid to the first surface 101 can be calculated, and the hot compress / cold compress / rinsing process of the patient's eyelid can be accurately controlled according to the operating parameters of the temperature action device 3. Furthermore, a third sensor 31 is provided to monitor the temperature of the temperature action device 3 in real time, and a fourth sensor 44 is provided to collect the ambient temperature, thereby improving the accuracy of temperature control during use of the treatment device. A blocking sensor 51 and a protection sensor 32 can also be provided. When an abnormality is detected in the second liquid / temperature action device 3, the liquid circulation path can be directly terminated, thereby improving safety during use.

Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
