Description

Eye therapy device Technical Field

[0001] The present invention relates to the field of mammalian eye treatment, and 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] Currently, artificial tears are the most effective treatment for dry eye. In addition to medications like artificial tears, physical therapy, such as warm compresses and massage, plays a crucial role in improving symptoms alongside medication. Warm compresses can dissolve abnormally solidified meibomian gland secretions, thereby unclogging the meibomian gland drainage channels. Massage can squeeze out lipid secretions stored in the meibomian glands, further unclogging the drainage channels.

[0004] However, the working principle of most existing methods is to control the inflation or leakage of the air bag through an air pump to perform a fixed massage on the eyes and surrounding areas. However, during this process, a fixed pressure is applied to the air bag, and the patient's eyelids can only be squeezed at a predetermined pressure. Directly controlling the inflation or leakage process through the air pump will repeatedly lead to unstable pressure, and it is impossible to accurately control or adjust the pressure during the massage process.

[0052] Embodiment: The present invention discloses an eye therapy device, referring to Figures 1 to 5, comprising:

[0053] The eye cup 1 includes a first surface 101, which is positioned inside the patient's eyelid during use. Specifically, the eye cup 1 can be a cup-shaped structure, including an outer surface of the cup, which is an arc-shaped surface that contacts the inner side of the patient's eyelid, namely the first surface 101. The eye cup 1 also includes an inner surface of the cup, namely a second surface 102, which is positioned relative to the eyeball 21 during use, with a certain gap between the eyeball 21 and the eyeball 21 to avoid the risk of direct contact with the eyeball 21 and causing damage to the patient's eye.

[0054] It should be noted that, as shown in Figures 2 and 3, the eye cup 1 in this embodiment can be used for ocular treatment, including but not limited to hot compresses and cold compresses. A cavity 103 is provided within the eye cup 1. The cavity 103 is connected to a liquid inlet pipe 11 and a liquid outlet pipe 12. The liquid inlet pipe 11 is connected to a liquid storage device 111. Liquid flows from the liquid storage device 111 through the liquid inlet pipe 11 into the cavity 103 and out of the cavity 103 through the liquid outlet pipe 12. Liquid at a certain temperature (determined by the cold / hot compress) can enter the cavity 103 through the liquid inlet pipe 11 and then flow out of the cavity 103 through the liquid outlet pipe 12, thereby performing heat exchange with the first surface 101, thereby achieving a cold / hot compress. The cavity 103 may not be connected to the first surface 101; alternatively, a plurality of through-holes may be provided on the first surface 101 to connect the first surface 101 to the cavity 103.

[0055] The squeezing unit 3 is opposite the first surface 101, and when the first surface 101 is positioned on the inner side of the eyelid, the squeezing unit 3 is positioned on the outer side of the eyelid and squeezes the outer side of the eyelid; the squeezing unit 3 squeezes the outer side of the eyelid. It should be noted that the squeezing unit 3 may include two parts, which are connected to the upper and lower sides of the eyecup 1, so that when the eyecup 1 is positioned, the squeezing unit 3 can be positioned corresponding to the upper and lower eyelids 222. The squeezing unit 3 can be fixed to the eyecup 1 as a whole, or it can be configured to be detachably connected to the eyecup 1. By way of example and not limitation, a slot can be provided at the bottom of the eyecup 1, and a buckle can be provided at the corresponding position where the squeezing unit 3 is connected to the eyecup 1. The detachable connection between the slot and the buckle is achieved by the connection between the slot and the buckle.

[0056] Specifically, referring to Figures 4 and 5 , the squeezing unit 3 includes a first acting portion 31 that contacts the outside of the eyelid, a second acting portion 32 that supports the first acting portion 31 and is connected to the eyecup 1, and a bladder cavity 33 located between the first and second acting portions 31, 32. The bladder cavity 33 is a deformable structure with an inner cavity and is located between the first and second acting portions 31, 32. When the bladder cavity 33 is inflated, the first and second acting portions 31, 32 move relatively apart (Figure 4), contacting the outside of the eyelid. When the bladder cavity 33 deflates, the first and second acting portions 31, 32 move closer together (Figure 5), moving away from the eyelid. When the first and second acting portions 31, 32 move relatively apart and the second acting portion 32 is secured to the eyecup 1, the first acting portion 31 can squeeze the outside of the patient's eyelid, achieving the squeezing process. The cooperation between the first and second acting portions 31, 32, and bladder cavity 33 creates pressure directed toward and acting on the outside of the eyelid.

[0057] Optionally, to achieve the aforementioned deformation of the bladder cavity 33, an air inlet 34 is provided on the side of the second action portion 32 facing away from the first surface 101. The second action portion 32 has an opening on the side closer to the first surface 101, which is sealed by the bladder cavity 33 and the first action portion 31. The pressure supply unit 4 can be connected to the air inlet 34 via a connecting tube 35, allowing gas to be input and enter the bladder cavity, thereby applying pressure to the second action portion 32. The gas then flows through the opening to the bladder cavity 33, causing the first action portion 31 to move away from the second action portion 32 under the action of the bladder cavity 33.

[0058] In this embodiment, based on the above, as an option, since the first action portion 31 needs to directly contact the outside of the patient's eyelid, it can be made of an elastic material such as silicone. Furthermore, the side of the first action portion 31 that contacts the outside of the eyelid forms a curved surface with a first curvature. The first action portion 31 can form a structure that contacts the outside of the eyelid, which is different from the existing airbag design that directly contacts the eyelid for compression. This allows the airbag cavity 33 to impact the first action portion 31 after impact, resulting in a more uniform compression effect on the outside of the eyelid.

[0059] Optionally, the second action portion 32 includes a concave arc-shaped surface 321, and the sac cavity 33 is connected to the concave arc-shaped surface 331 through an opening. Since the concave arc-shaped surface 331 wraps the sac cavity 33 to limit the direction of pressure after the sac cavity 33 is deformed, the pressure is concentrated on the first action portion 31 to squeeze the eyelid, and only deforms in the vertical direction. Preferably, the first action portion 31 has a curved surface with a first curvature, and the two ends of the second action portion 32 extend out of the two ends of the first action portion 31 respectively, and bend toward the first action portion 31 to form a second curvature, wherein the second curvature is greater than the first curvature. The two ends of the second action portion 32 extend out of the two ends of the first action portion 31, forming a shape similar to the second action portion 32 wrapping the first action portion 31, further reducing the deformation of the sac cavity 33 to the circumferential side after inflation, so that the pressure squeezes the eyelid along the direction perpendicular to the length of the first action portion 31 and the second action portion 32.

[0060] In a preferred embodiment, the capsule cavity 33 adopts a multi-layer nested structure in a direction perpendicular to its length. For example, as shown in FIG4 , the capsule cavity 33 includes a first capsule cavity 331 and a second capsule cavity 332. The first capsule cavity 331 is stacked on the second capsule cavity 332 in the direction perpendicular to its length to form a multi-layer IOU structure. The first capsule cavity 331 is connected to the second capsule cavity 332, and the first capsule cavity 331 is connected to the first action portion 31, while the second capsule cavity 332 is connected to the second action portion 32. When inflated, the multi-layer nested structure extends upward in the direction perpendicular to its length, and when deflated, the multi-layer nested structure retracts downward in the direction perpendicular to its length.

[0061] Through the specific structure of the above-mentioned first action part 31, the second action part 32, and the capsule cavity 33, the action force can be limited to deformation of other surfaces and only deform in the vertical direction. Combined with the curvature of the concave arc surface 321, the action force is uniform and concentrated, thereby achieving precise extrusion control.

[0062] The pressure supply unit 4 includes a positive pressure storage container 41 and a power pump 42 to provide pressure to the bladder cavity 33. The positive pressure storage container 41 is provided, and the power pump 42 functions to store a stable pressure at a threshold within the positive pressure storage container 41, thereby providing a stable pressure to the bladder cavity 33. When the bladder cavity 33 is inflated, a stable pressure is always provided. After each deformation of the bladder cavity 33, the first action portion 31 compresses the eyelid, thus ensuring a stable output for each compression action. The addition of the pressure-stabilizing cylinder (i.e., the positive pressure storage container 41) allows for a good balance between smooth pressure control and rapid pressure switching (in conjunction with multiple control valves).

[0063] A plurality of control valves are used to control the on and off of the pressure in and out of the sac cavity 33. In this embodiment, a control valve is provided to control the pressure of the sac cavity 33 to perform the squeezing action, and a control module 7 is also included to control the pressure supply unit 4 and each control valve to control and generate a variety of treatment modes. The control unit controls the plurality of control valves to achieve different pressure changes inside the sac cavity 33 under different treatment modes, so that the first action part 31 on the squeezing unit 3 moves relatively away from the second action part 32 at different frequencies and displacements to squeeze the outside of the eyelid, thereby achieving precise control of the squeezing operation to suit different patients. Specifically, different frequencies can be controlled by controlling the on and off time of the pressure in the sac cavity 33, and different displacements can be achieved by providing stable pressures of different thresholds by the above-mentioned pressure supply unit 4. Therefore, it is different from the existing problem that it can only connect an air pump to inflate the airbag and squeeze the eyelid, and cannot accurately control or adjust the pressure.

[0064] In this embodiment, specifically, to achieve pressure control in the bladder cavity 33, the control valve includes:

[0065] The first control valve 51 is disposed on the positive pressure storage container 41 and cooperates with the power pump 42 to control the pressure provided. The first control valve 51 can be connected to the atmosphere or the negative pressure device 8, so that the first control valve 51 adjusts the pressure of the positive pressure storage container 41 to always maintain a certain threshold value based on the control parameters of the power pump 42, thereby maintaining a stable pressure in the bladder cavity 33.

[0066] The second control valve 52 is connected between the pressure supply unit 4 and the squeezing unit 3. The second control valve 52 can control the on-off frequency of the pressure supply unit 4 providing pressure to the bladder cavity 33, thereby coordinating different treatment modes set by the control unit.

[0067] The third control valve 53 is used to connect the extrusion unit 3 to ambient air pressure or to the negative pressure device 8. This third control valve 53 is used to connect to the atmosphere or the negative pressure device 8 to achieve decompression of the bladder cavity 33. It cooperates with the second control valve 52 to control the on / off duration of the pressure within the bladder cavity 33, thereby adjusting the extrusion frequency of the first action portion 31. For illustration, in this embodiment, each negative pressure device 8 can be the same or different, and can be configured according to the actual scenario.

[0068] In this embodiment, based on the above-mentioned control valves and the pressure supply unit 4, flexible control can be implemented to execute a multi-mode extrusion action so as to be selected according to different scenarios. Specifically, the following settings can be made:

[0069] In an optional embodiment, the pressure supply unit 4, the first control valve 51, and the second control valve 52 cooperate to control the formation of linear pressurization within the bladder cavity 33, thereby generating a first treatment mode. Specifically, as an example, the linear pressurization within the bladder cavity 33 can be achieved by using the power pump 42 in conjunction with the first control valve 51 to linearly increase the pressure in the positive pressure storage container 41. The second control valve 52 then controls the pressure output from the positive pressure storage container 41 to the bladder cavity 33, continuously switching the pressure value in the positive pressure storage container 41 on and off, thereby achieving linear pressurization within the bladder cavity 33 as the second control valve 52 is switched on and off. In this first treatment mode, continuous pressure can be delivered to the patient's eyelid.

[0070] In an optional embodiment, a second treatment mode is generated based on the pressure supply unit 4 and the second control valve 52 cooperating to control the formation of a horizontal pressure within the bladder cavity 33. Specifically, as an example, the pressure in the positive pressure storage container 41 is maintained at a certain threshold by the power pump 42 cooperating with the first control valve 51. The second control valve 52 then cooperates with the third control valve 53 to control the inflation and deflation of the bladder cavity 33. During each inflation, the horizontal pressure is maintained for a period of time, so that the first action part 31 continues to compress the outer side of the eyelid for a period of time, ensuring that the patient's eyelid is compressed for a sustained period of time.

[0071] In an optional embodiment, a third treatment mode is generated based on the pressure supply unit 4, the second control valve 52, and the third control valve 53 cooperating to control the pulse pressure within the bladder cavity 33. Specifically, as an example, a pulse pressure of 40 kPa can be generated. The power pump 42 cooperates with the first control valve 51 to maintain the pressure in the positive pressure storage container 41 at 40 kPa. The second control valve 52 and the third control valve 53 are opened and closed at a certain frequency, so that the first action part 31 continuously and frequently compresses the patient's eyelid.

[0072] Based on the various treatment modes provided in this embodiment, including but not limited to the above modes, one or more of the above treatment modes can also be selected, such as running in the first treatment mode for 5 minutes and then running in the second treatment mode, etc. Other modes that can be implemented according to each control valve and pressure supply unit 4 are also possible, and they are not listed here one by one.

[0073] The present invention utilizes a positive pressure storage container 41 and multiple control valves to inflate the bladder cavity 33. Compared to directly using a power pump to inflate the bladder cavity, this method not only stabilizes the pressure in the bladder cavity and allows for quick and precise adjustment, but also facilitates multiple treatment modes. Patients with varying sensitivities can simply be treated by controlling the stable pressure within the positive pressure storage container 41 at different levels.

[0074] In the present invention, as shown in FIG6 , FIG7 , or FIG8 , in a preferred embodiment, the eye therapy device further comprises an integrated panel 6 , comprising a liquid outlet port 62 , a liquid inlet port 61 , and a pressure port 63 . The pressure port 63 is connected to a plurality of control valves. The eye cup 1 and the extrusion unit 3 are detachably connected to the respective ports on the integrated panel 6 via the liquid inlet pipe 11 , the liquid outlet pipe 12 , and the connecting pipe 35 , respectively. Specifically, as shown in FIG8 , the liquid inlet pipe 11 , the liquid outlet pipe 12 , and the connecting pipe 35 can be integrated via a connecting portion 9 , which is provided with a port 91 corresponding to the liquid inlet port 61 , a port 92 corresponding to the liquid outlet port 62 , and a port 93 corresponding to the pressure port 63 . Through the one-to-one correspondence between the ports, the eye cup 1 and the extrusion unit 3 are integrated and detachable. The integrated panel 6 can also integrate other components, including but not limited to a water storage device 111 for storing liquid entering the eye cup 1 , thereby reducing space usage and facilitating the replacement of both the eye cup 1 and the extrusion unit 3 .

[0075] In a preferred embodiment, the liquid outlet pipe 12 is used to extract the liquid entering the cavity from the liquid inlet pipe 11. In order to control the flow state of the liquid, a negative pressure device 8 can be connected to the liquid outlet pipe 12. The liquid is extracted from the cavity through the negative pressure device 8, thereby controlling the liquid with a certain temperature to stably pass through the cavity at a preset flow rate and perform heat exchange with the first surface 101. Further optionally, since the negative pressure device 8 is used to extract the liquid, the extracted liquid can be collected so that it can be discharged autonomously, forming an autonomous liquid circulation path for hot compress / cold compress. Specifically, the negative pressure device 8 includes a negative pressure container for connecting to the liquid outlet pipe 12 and loading the treatment liquid, and a water outlet is provided on the negative pressure container. After the negative pressure container is connected to the pressure supply unit 4 so that the pressure supply unit 4 provides a certain pressure, the liquid in the negative pressure container is discharged autonomously through the water outlet.

[0076] As an illustration, liquid passing through the cavity is drawn out by negative pressure and then enters the negative pressure container. Within the negative pressure container, liquid is then drawn out by the negative pressure device 8. A flow rate control device, such as a peristaltic pump / power pump, may also be provided in the liquid inlet pipe 11, so that the liquid flows uniformly through the liquid inlet pipe 11 and the liquid outlet pipe 12 at a preset stable flow rate (the flow rate can be controlled by adjusting the operating parameters of the negative pressure device 8 or the peristaltic pump / power pump). The use of piping allows the pressure supply unit 4 to provide a certain pressure, allowing the liquid in the negative pressure container to be further discharged from the water outlet, thereby preventing the liquid discharged from the liquid outlet pipe 12 from accumulating in the negative pressure container.

[0077] In this embodiment, an eye therapy device is provided, in which pressure is provided to the capsule cavity 33 by a supply unit, and then the pressure is transmitted to the first action part 31. The pressure can be provided by gas or liquid. When gas is used to provide pressure, as shown above as an example, an air inlet 34 connected to the capsule cavity 33 can be provided on the second action part 32, so that the gas stored in the positive pressure storage container 41 can be conducted from the air inlet 34 to the capsule cavity 33 (the first capsule cavity 331 and the second capsule cavity 332 are connected) for inflation. When liquid is used to provide pressure, the liquid can be directly stored in the positive pressure storage container 41, and the second control valve 52 is used to control the on-off, and the amount of liquid entering the capsule cavity 33 each time controls the pressure generated by each squeezing action. Alternatively, gas and liquid are used to provide pressure. As an optional embodiment, the first capsule cavity 331 and the second capsule cavity 332 are not connected to each other. The first capsule cavity 331 is close to the side of the first action part 31, and the second capsule cavity 332 is connected to the pressure supply unit 4. On either side of the first bladder cavity 331 are a liquid inlet branch (not shown) and a liquid outlet branch (not shown), each connected to the liquid inlet tube 11 and the liquid outlet tube 12. A one-way valve is also installed on the side of the liquid inlet branch connected to the liquid inlet tube 11 to prevent liquid in the liquid inlet branch from flowing back into the liquid inlet tube 11 and causing contamination. A certain amount of gas can be stored in the second bladder cavity 332 in advance; or it can be directly connected to the pressure supply unit 4 to adjust the inflation or deflation of the second bladder cavity 332 during the squeezing process. Simultaneously, the first bladder cavity 331 is connected to the liquid inlet tube 11 and the liquid outlet tube 12 via the liquid inlet branch and the liquid outlet branch, respectively. That is, when applying a hot or cold compress, liquid enters the cavity and also enters the first bladder cavity. The liquid entering the first bladder cavity 331 generates a certain amount of pressure, further applying a certain amount of pressure to the first action part 31, while also affecting the outer side of the eyelid through heat conduction. This allows the outer side of the eyelid to be squeezed while also applying a hot or cold compress, achieving precise control of the squeezing action and multi-mode selection.

[0078] The eye therapy device provided in this embodiment includes an eye cup 1. A cavity can be provided in the eye cup 1 to allow liquid of a certain temperature to pass through, thereby transferring heat to a first surface 101 in contact with the patient's eyelid, thereby applying a hot or cold compress to the eyelid. A squeezing unit 3 is connected to the eye cup 1 and can be configured to include two parts, corresponding to the outer side of the upper eyelid 221 and the outer side of the lower eyelid 222, respectively. A first action portion 31 of the squeezing unit 3 is in contact with the eyelid, and a second action portion 32 is connected to the eye cup 1. The first action portion 31 and the second action portion 32 are connected by a sac cavity 33. A pressure supply unit 4 is used to apply pressure to the sac cavity 33, so that the sac cavity 33 deforms and pushes the first action portion 31 away from or closer to the second action portion 32, thereby squeezing the eyelid.

[0079] Specifically, a positive pressure storage container 41 is provided to realize steady-state input of pressure in the capsule cavity 33 of the extrusion unit 3, and a plurality of control valves are also provided (such as a first control valve 51 provided on the positive pressure storage container 41, a second control valve 52 for controlling the connection between the pressure supply unit 4 and the capsule cavity 33, a third control valve 53 for connecting the capsule cavity 33 to realize decompression, etc.). The two cooperate to control the capsule cavity 33 to form different internal pressure changes, thereby generating a variety of treatment modes, specifically including but not limited to linear pressurization, horizontal, pulse and other pressure change states, thereby realizing multi-mode control of pressure stability when achieving eye treatment with the assistance of massage, so as to be applicable to a wider range of scenarios.

[0080] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. 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.
