Description

Technical Field

[0001] This invention belongs to the field of medical equipment technology, and in particular relates to an integrated cold and hot compress eye mask for postoperative ophthalmic care. Background Technology

[0002] Ophthalmic surgery is a core method for treating eye diseases such as refractive errors, cataracts, glaucoma, retinal diseases, oculoplastic deformities, and eye injuries. Postoperative cold and warm compresses are indispensable routine physical care measures during the perioperative period of ophthalmic surgery. Currently, in clinical and home care, traditional methods are still the main approach. Cold compresses often use homemade ice packs, frozen wet towels, or disposable medical cold compress ice packs, while warm compresses often use hot wet towels, hot water bottles, or disposable steam eye masks.

[0003] When using cold or hot compresses for cold and hot compress care, there is a common problem that the cold and heat cannot be evenly applied to the surgical area of ​​the patient's eye. The cold / hot compress itself is a soft bag, and the gel or liquid medium inside is prone to flow and displacement, causing local concentration of cold / heat. At the same time, the area around the human eye has a physiological curved structure with sunken orbits and protruding eyeballs. The flat soft compress cannot achieve uniform adhesion to the surgical area. Slight displacement or compression during the wearing process will result in local overcooling / overheating of the application area and no effective cooling / heating effect in some areas.

[0004] Excessive local temperature can easily cause burns to the eyelid skin and worsen congestion and exudation in the surgical area, while excessively low temperature can easily cause frostbite to the eyelid skin, spasm of the orbicularis oculi muscle, and temporary blurred vision. Post-operative ophthalmic patients have reduced visual perception and decreased sensitivity to hot and cold stimuli, further amplifying the aforementioned risks of injury. Furthermore, uneven exposure to heat and cold can lead to inconsistent effects on swelling reduction, pain relief, and bruising resolution in the surgical area, resulting in uneven recovery and prolonging the postoperative recovery period. For patients with corneal sensitivity or after glaucoma surgery, sudden temperature differences can also induce fluctuations in intraocular pressure, directly affecting the surgical prognosis. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an integrated cold and hot compress eye mask for post-operative ophthalmic care.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated cold and hot compress nursing eye mask for postoperative ophthalmic surgery, comprising an eye mask shell, the lower end of which is configured as an arc structure conforming to the contour of the human face, and an elastic strap for wearing and fixing is fixed on the outer side of the eye mask shell, and further comprising two temperature equalization components symmetrically arranged on the eye mask shell, an adjustable component for driving the two temperature equalization components to move along the axial direction of the eye mask shell, an annular inflatable airbag, an air supply component, a PLC microcontroller, and a battery pack; The upper end of the goggle shell has two openings that correspond one-to-one with the temperature equalization components and are used for the axial movement of the temperature equalization components. The two temperature equalization components are symmetrically arranged to deliver uniform cold / hot compress energy to the patient's eyes; The adjustable component is fixed to the eye mask shell. The power output end of the adjustable component is fixedly connected to two temperature equalization components. It is used to adjust the application pressure of the temperature equalization components on the patient's eyes and can drive the temperature equalization components to retract intermittently to achieve slow-release care of cold / hot compress. The annular inflatable airbag is fixed to the lower edge of the eye mask shell and is arranged corresponding to the lateral bone surface area of ​​the human eye socket. The air supply component is fixed to the upper end of the eye mask shell. The air inlet of the air supply component is linked to the temperature equalization component, and the air outlet of the air supply component is connected to the annular inflatable airbag. It is used to supply air to the annular inflatable airbag for expansion when the temperature equalization component moves toward the eyes. The PLC microcontroller and the battery pack are both fixed to the inner wall of the goggle shell. The battery pack supplies power to the PLC microcontroller and the adjustable component. The PLC microcontroller is electrically connected to the adjustable component and is used to control the timing and stroke of the adjustable component.

[0007] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, the temperature equalization component includes a temperature insulation frame, a temperature insulation cover, a heat-conducting plate, multiple heat-conducting rods, a heat-conducting sealing film, and medical heat-conducting liquid silicone. The heat insulation cover is detachably connected to the upper opening of the heat insulation frame. The heat-conducting plate is horizontally fixed inside the heat insulation frame. Multiple heat-conducting rods are vertically fixed to the side of the heat-conducting plate closest to the patient's eyes. The heat-conducting sealing film is sealed and fixed to the lower opening of the heat insulation frame. The medical heat-conducting liquid silicone fills the cavity between the heat-conducting plate and the heat-conducting sealing film, and the medical heat-conducting liquid silicone completely covers all the heat-conducting rods. The side of the heat-conducting plate away from the heat-conducting rods is used to place a cold compress or a hot compress.

[0008] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, the adjustable component includes an electric screw drive mechanism and an adjustment plate. The electric screw drive mechanism is vertically fixed to the outer wall of the eye mask shell. The adjustment plate is driven by the electric screw drive mechanism. The two ends of the adjustment plate are respectively fixedly connected to the outer walls of the insulation frames of the two temperature equalization components. The electric screw drive mechanism is electrically connected to a PLC microcontroller.

[0009] In the above-mentioned integrated cold and hot compress nursing eye mask after ophthalmic surgery, the air supply component includes multiple compressed air bladders, a connecting plate, and an air supply pipe. The lower end of the compressed air bladder is fixed to the upper surface of the eye mask shell. One end of the connecting plate is fixedly connected to the outer wall of the temperature insulation frame of the temperature equalization component, and the other end of the connecting plate is fixedly connected to the upper end of the compressed air bladder. One end of the air supply pipe is connected to the air outlet of the compressed air bladder, and the other end of the air supply pipe is connected to the inner cavity of the annular inflatable air bladder.

[0010] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, a medical thermally conductive nonwoven fabric is detachably bonded to the side of the thermally conductive sealing film away from the medical thermally conductive liquid silicone. The medical thermally conductive nonwoven fabric is a disposable sterile consumable.

[0011] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, multiple heat-conducting rods are evenly distributed in a matrix or radial pattern on the end face of the heat-conducting plate, and the spacing between adjacent heat-conducting rods is equal.

[0012] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, the upper opening of the heat insulation cover and the heat insulation frame are detachably connected by a snap-fit ​​structure, and a sealing heat insulation pad is provided at the connection between the heat insulation cover and the heat insulation frame.

[0013] In the above-mentioned integrated cold and hot compress eye mask for postoperative ophthalmic surgery, the annular inflatable airbag is a medical flexible silicone airbag, which is arranged in a ring around the periphery of the human eye socket bone surface area and does not cover the corresponding area of ​​the eyeball.

[0014] Compared with existing technologies, the advantages of this invention are as follows: 1. By using a temperature equalization component, a continuous, seamless heat conduction path is constructed: "heat-conducting plate receives energy → array-type heat-conducting rods distribute heat at multiple points → medical-grade heat-conducting liquid silicone provides uniform heating throughout the entire area → heat-conducting sealing film outputs heat evenly." This transforms the local energy of the cold / hot compress into a uniform temperature field across the entire application surface, keeping the temperature deviation in the ocular surface contact area within ±1℃. This effectively avoids the risks of frostbite and burns caused by excessive local cold or heat, and prevents problems such as orbicularis oculi muscle spasm, intraocular pressure fluctuations, and increased congestion and exudation in the surgical area caused by local temperature stimulation. The nursing effects of reducing swelling and pain, promoting blood circulation and removing blood stasis are more stable and uniform, effectively accelerating the patient's postoperative recovery.

[0015] 2. The adjustable components allow for precise adjustment of the application pressure, tailoring the optimal pressure to the patient's eye shape, degree of swelling in the surgical area, and type of surgery. This ensures a close fit between the application surface and the eyelid, improving heat conduction efficiency, while completely avoiding the safety risks of excessive pressure compressing the eyeball and increasing intraocular pressure. Furthermore, the intermittent slow-release nursing program preset by the PLC microcontroller enables a cyclical nursing care approach of "10 minutes of continuous application → 5 minutes of pressure reduction," avoiding continuous stimulation of the eye tissues from prolonged hot and cold compresses. This is particularly suitable for surgical scenarios involving highly sensitive eye tissues, such as glaucoma, corneal transplantation, and post-vitrectomy procedures, significantly improving patient comfort and compliance.

[0016] 3. Through the inflatable airbag and air supply components, the ring-shaped inflatable airbag forms a sealed chamber between the eye mask shell and the patient's face, which greatly reduces the loss of cold / heat to the outside, improves the stability of temperature maintenance, extends the single use time of the hot and cold compresses, and reduces the replacement frequency. In addition, the ring-shaped inflatable airbag only acts on the outer orbital bone surface area, without covering or compressing the corresponding area of ​​the eyeball, thus completely avoiding the risk of increased intraocular pressure from a structural perspective, and significantly improving safety.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-6 As shown, an integrated cold and hot compress nursing eye mask for postoperative ophthalmic surgery includes an eye mask shell 1. The lower end of the eye mask shell 1 is designed with an arc structure that conforms to the contour of the human face, adapting to the physiological curvature of the human eye area and avoiding gaps when wearing it. An elastic strap 2 for wearing and fixing is fixed on the outside of the eye mask shell 1. The elastic strap 2 is a medical elastic band with adjustable length to adapt to patients with different head circumferences. It also includes two temperature equalization components 3 symmetrically arranged on the goggle shell 1, an adjustable component 4 for driving the two temperature equalization components 3 to move axially along the goggle shell 1, an annular inflatable airbag 5, an air supply component 6, a PLC microcontroller 7 and a battery pack 8. The upper end of the goggle shell 1 has two openings that correspond one-to-one with the temperature equalization components 3 and are used for the axial movement of the temperature equalization components 3.

[0021] Two temperature equalization components 3 are symmetrically arranged to deliver uniform cold / hot compress energy to the patient's eyes. The temperature equalization component 3 includes a temperature insulation frame 31, a temperature insulation cover plate 32, a heat conduction plate 33, multiple heat conduction rods 34, a heat conduction sealing film 35, and medical heat conduction liquid silicone 36. The temperature insulation frame 31 is a rectangular frame with openings at the top and bottom, and is made of medical-grade heat insulation PP material to prevent cold / heat from being lost to the outside. The upper openings of the heat insulation cover plate 32 and the heat insulation frame 31 are detachably connected by a snap-fit ​​structure. A sealing heat insulation pad is provided at the connection between the heat insulation cover plate 32 and the heat insulation frame 31 to improve the heat insulation and sealing effect. The heat-conducting plate 33 is horizontally fixed inside the heat insulation frame 31, and multiple heat-conducting rods 34 are vertically fixed on the side of the heat-conducting plate 33 near the patient's eye. The multiple heat-conducting rods 34 are evenly distributed in a matrix or radial pattern on the end face of the heat-conducting plate 33, and the spacing between adjacent heat-conducting rods 34 is equal, so as to achieve uniform heat distribution at multiple points and eliminate local temperature differences. The thermally conductive sealing film 35 is fixedly sealed at the lower opening of the heat insulation frame 31. It is made of high thermal conductivity medical polyurethane film or medical silicone film with a thickness of 0.1-0.3mm. It has good flexibility, strong thermal conductivity and excellent sealing performance. The medical thermally conductive liquid silicone 36 fills the cavity between the heat-conducting plate 33 and the thermally conductive sealing film 35. The medical thermally conductive liquid silicone 36 completely covers all the heat-conducting rods 34. It can not only evenly distribute the energy of the heat-conducting rods 34 to the entire thermally conductive sealing film 35, but also play a flexible buffering role to avoid the heat-conducting rods 34 from causing hard pressure on the eyes. It is adapted to the physiological curvature of the eyes. The side of the heat-conducting plate 33 away from the heat-conducting rods 34 is used to place the cold compress pack or the hot compress pack. It can be quickly replaced by opening the heat insulation cover 32, and the cold compress and hot compress modes can be switched conveniently.

[0022] The side of the thermally conductive sealing film 35 facing away from the medical thermally conductive liquid silicone 36 is detachably bonded with medical thermally conductive non-woven fabric 9. The medical thermally conductive non-woven fabric 9 is a disposable sterile consumable, used by a single person for a single time, and is easy to replace. It meets the requirements for sterile care after ophthalmic surgery and avoids cross-infection.

[0023] The adjustable component 4 is fixed on the eye mask shell 1. The power output end of the adjustable component 4 is fixedly connected to two temperature equalization components 3. It is used to adjust the application pressure of the temperature equalization components 3 on the patient's eyes and can drive the temperature equalization components 3 to retract intermittently to achieve slow-release care of cold / hot compress. The adjustable component 4 includes an electric screw drive mechanism 41 and an adjusting plate 42. The electric screw drive mechanism 41 is vertically fixed to the outer wall of the eye mask shell 1. The adjusting plate 42 is connected to the electric screw drive mechanism 41. The two ends of the adjusting plate 42 are respectively fixedly connected to the outer wall of the insulation frame 31 of the two temperature equalization components 3. The electric screw drive mechanism 41 is electrically connected to the PLC microcontroller 7, which can synchronously drive the two temperature equalization components 3 to move along the port axis to achieve precise adjustment of the application pressure.

[0024] The annular inflatable airbag 5 is fixed to the lower edge of the eye shield shell 1. The annular inflatable airbag 5 is a medical flexible silicone airbag, which is arranged in a ring around the bone surface area of ​​the human eye socket. It does not cover the corresponding area of ​​the eyeball. After inflation, it only applies pressure to the bone surface of the eye socket and will not compress the eyeball, effectively avoiding the risk of increased intraocular pressure.

[0025] The air supply component 6 is fixed to the upper end of the eye mask shell 1. The air inlet of the air supply component 6 is linked to the temperature equalization component 3, and the air outlet of the air supply component 6 is connected to the annular inflatable airbag 5. It is used to supply air to the annular inflatable airbag 5 for expansion when the temperature equalization component 3 moves toward the eyes. The air supply assembly 6 includes multiple compressed air bladders 61, a connecting plate 62, and an air supply pipe 63. The lower end of the compressed air bladder 61 is fixed to the upper end face of the eye mask shell 1. One end of the connecting plate 62 is fixedly connected to the outer wall of the heat insulation frame 31 of the temperature equalization assembly 3, and the other end of the connecting plate 62 is fixedly connected to the upper end of the compressed air bladder 61. One end of the air supply pipe 63 is connected to the air outlet of the compressed air bladder 61, and the other end of the air supply pipe 63 is connected to the inner cavity of the annular inflatable air bladder 5. When the temperature equalization assembly 3 moves toward the patient's eye, the connecting plate 62 squeezes the compressed air bladder 61 downward. The air in the compressed air bladder 61 enters the annular inflatable air bladder 5 through the air supply pipe 63, causing the annular inflatable air bladder 5 to inflate.

[0026] Both the PLC microcontroller 7 and the battery pack 8 are fixed to the inner wall of the eye mask shell 1. The battery pack 8 supplies power to the PLC microcontroller 7 and the adjustable component 4. The PLC microcontroller 7 is electrically connected to the adjustable component 4 and is used to control the timing and stroke of the adjustable component 4. The PLC microcontroller 7 has a preset pressure adjustment program and an intermittent slow-release care program. The intermittent slow-release care program is as follows: after each drive of the temperature equalization component 3 to continuously apply pressure to the eye for 10 minutes, the temperature equalization component 3 is automatically driven to retract and depressurize for 5 minutes, and this cycle is repeated to avoid stimulation of the eye tissue from prolonged continuous hot and cold compresses. At the same time, the PLC microcontroller 7 can preset exclusive care programs for different surgical types. For different surgical procedures such as oculoplastic surgery, glaucoma surgery, retinal surgery, and corneal surgery, the corresponding pressure parameters, slow-release sequence, and care duration are matched to meet the needs of different clinical scenarios.

[0027] The operating principle of the present invention is described as follows: Take a brand new disposable sterile medical thermally conductive nonwoven fabric 9 and detachably attach it to the side of the thermally conductive sealing film 35 away from the medical thermally conductive liquid silicone 36 to complete the sterile protection preparation of the layer that directly contacts the patient's eyes, ensuring that the consumables fit flat and without wrinkles or lifting. Based on the patient's postoperative recovery stage nursing needs, perform the corresponding media filling operation: for acute care during the 24-48 hour postoperative period, use a medical cold compress; for recovery care after confirming no active bleeding 48-72 hours postoperatively, use a medical hot compress. Open the insulation cover 32 at the upper opening of the insulation frame 31, and place the corresponding cold or hot compress steadily on the side of the heat-conducting plate 33 away from the heat-conducting rod 34. After filling, fasten the insulation cover 32, and lock it in place through the buckle structure. The sealing insulation pad at the connection point achieves insulation and sealing to prevent the loss of cold / heat to the outside. The eye shield shell 1 is worn and fixed to the patient's head by the elastic strap 2. The wearing position is adjusted so that the ring-shaped inflatable air bladder 5 at the lower edge of the eye shield shell 1 is precisely aligned with the lateral bone surface area of ​​the patient's orbit. This ensures that the ring-shaped inflatable air bladder 5 does not cover or compress the corresponding area of ​​the eyeball throughout the process. The tightness of the elastic strap 2 is adjusted so that the eye shield shell 1 is initially and stably fixed around the patient's eyes without loosening, displacement, or excessive pressure. This ensures that the two temperature equalization components 3 are aligned with the surgical areas of the patient's eyes respectively. The PLC microcontroller 7 sends a forward drive command to the electric screw drive mechanism 41 of the adjustable component 4. The electric screw drive mechanism 41 rotates forward, driving the adjustment plate 42 connected to it to move axially along the eye cover shell 1 towards the patient's eye. Simultaneously, the adjustment plate 42 drives the two temperature equalization components 3 fixed at both ends to move smoothly along the opening of the eye cover shell 1 towards the patient's eye until the medical thermally conductive non-woven fabric 9 is tightly attached to the patient's eyelid and the preset target application pressure is reached. Then, the electric screw drive mechanism 41 automatically locks, completing the precise adjustment of the application pressure. This process can achieve precise adjustment of the application pressure, adapting to the specific needs of the patient's eye shape, the degree of swelling in the surgical area, and the type of surgery. It ensures a tight fit between the application surface and the eyelid to improve heat conduction efficiency, while completely avoiding the safety hazard of excessive pressure compressing the eyeball and increasing intraocular pressure. As the temperature equalization component 3 moves toward the patient's eyes, the connecting plate 62 of the air supply component 6 simultaneously compresses the air bladder 61 downwards. The air inside the air bladder 61 is continuously delivered to the inner cavity of the annular inflatable air bladder 5 through the air supply pipe 63 connected to its air outlet. This causes the air pressure inside the annular inflatable air bladder 5 to increase and expand synchronously, closely fitting the patient's facial skin around the eyes. On the one hand, this achieves secondary stabilization and fixation of the eye mask shell 1, preventing the eye mask from shifting during the nursing process. On the other hand, it forms a sealed chamber between the eye mask shell 1 and the patient's face, significantly reducing the loss of cold / heat output from the temperature equalization component 3 to the outside, improving the stability of temperature maintenance, and extending the single-use time of the cold / hot compress pack. After the application pressure is adjusted, the device enters continuous hot and cold compress care mode. The cold / heat of the cold / hot compress pack is evenly distributed throughout the entire eye area through a specially designed continuous and uninterrupted heat conduction path. The specific conduction process is as follows: the cold / heat of the cold / hot compress pack is first transferred to the heat-conducting plate 33 that is in close contact with it. After the heat-conducting plate 33 completes the initial temperature uniformity, it is evenly transferred to multiple heat-conducting rods 34 that are vertically fixed to the end face of the heat-conducting plate 33 and distributed in a matrix / radial array. The heat-conducting rods 34 achieve multi-point uniform heat distribution, dispersing the energy to the entire application area. Subsequently, the energy of the heat-conducting rods 34 is evenly transferred to the entire eye area. The medical thermally conductive liquid silicone 36 covering the outside eliminates local temperature differences and forms a uniform temperature field throughout the entire area through the uniform heating of the medical thermally conductive liquid silicone 36. The uniform cold / heat continues to be transferred to the thermally conductive sealing film 35 that is sealed and fixed at the lower end of the thermal insulation frame 31. Finally, through the medical thermally conductive non-woven fabric 9 bonded to the outside of the thermally conductive sealing film 35, it acts evenly and gently on the patient's eyelid surgical area, so that the temperature deviation of the contact area of ​​the ocular surface is controlled within ±1℃, realizing uniform cold and hot compress care without temperature difference in the entire eye area, effectively avoiding the risk of frostbite and burns caused by excessive local cold or heat, and ensuring uniform and stable nursing effects of reducing swelling and pain and promoting blood circulation. During the nursing process, the PLC microcontroller 7 automatically executes cyclical nursing control according to the preset intermittent slow-release nursing program. The specific process is as follows: Single-cycle continuous care phase: Drive the temperature equalization component 3 to maintain a close fit and continuously output uniform cold / heat to the patient's eyes for 10 minutes; Single-cycle retraction and slow-release phase: After the continuous nursing time reaches the preset value, the PLC microcontroller 7 sends a reverse drive command to the electric screw drive mechanism 41. The electric screw drive mechanism 41 rotates in reverse and drives the two temperature equalization components 3 to retract a preset distance away from the patient's eyes along the opening through the adjustment plate 42, so that the medical thermal conductive non-woven fabric 9 is completely separated from the patient's eyelids, stopping the continuous hot and cold stimulation to the eyes, and entering the slow-release nursing phase, which lasts for 5 minutes. Cyclic execution: After the slow-release nursing time reaches the preset value, the PLC microcontroller 7 drives the electric screw transmission mechanism 41 to rotate in the forward direction again, driving the temperature equalization component 3 to reset to the preset fitting position, and re-entering the continuous nursing stage. This cycle repeats until the preset total nursing time is reached. Through this intermittent slow-release cycle design, the continuous stimulation of eye tissues by prolonged continuous hot and cold compresses can be effectively avoided. It is especially suitable for surgical scenarios with highly sensitive eye tissues, such as glaucoma, corneal transplantation, and vitreoretinal surgery, which significantly improves patient nursing comfort and compliance. After the preset total nursing time ends, the PLC microcontroller 7 automatically sends a reverse drive command to the electric screw transmission mechanism 41, driving the temperature equalization component 3 to completely retract to the initial position, relieving the pressure of the dressing on the patient's eyes. During the retraction of the temperature equalization component 3, the connecting plate 62 moves upward synchronously, relieving the compression of the compressed air bag 61. The air in the annular inflatable air bag 5 is returned to the compressed air bag 61 through the air supply pipe 63, releasing the sealing and fixation around the eyes. Loosen the elastic straps 2, remove the goggle cover 1 from the patient's head, tear off the used medical thermal conductive non-woven fabric 9, and dispose of it according to the medical waste disposal regulations. Reuse is strictly prohibited.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
