Description

TECHNICAL FIELD

[0001] The application relates to the technical field of negative pressure eye masks, in particular to a negative pressure eye mask for postoperative bathing of ophthalmology. BACKGROUND

[0002] After ophthalmic surgery, there is a wound on the eye, at this time, the defense barrier of the eye is temporarily damaged, and the resistance is significantly decreased. If the bathing water containing bacteria, viruses, fungi and other microorganisms accidentally enters the eyes, it is easy to cause infection, and light causes redness, pain, and increased secretion. Heavy may cause vision loss, surgery failure, and even require secondary surgery intervention. In addition, the postoperative eye tissue is in a sensitive state, and the temperature change of water, the water flow pressure or the impurities (such as disinfectants, minerals) contained in the water may directly stimulate the wound or the ocular surface, induce inflammation and interfere with the normal healing process. Therefore, a special device is needed to effectively block the living water from entering the eyes during bathing.

[0003] The existing negative pressure eye mask constructs a negative pressure environment by extracting internal gas through an air extraction device, and utilizes the characteristic that the external pressure is greater than the internal pressure to make the edge of the eye mask closely contact the skin around the eyes, so as to realize the effect of preventing water from entering. However, for postoperative patients of ophthalmology, there is a wound on the eye, and the negative pressure formed on the inner side of the eye mask is easy to cause irritation to the wound, causing discomfort. At the same time, the rubber material at the bottom of the eye mask is easy to be worn out due to friction and other factors, thereby causing air leakage, which directly leads to the failure of the negative pressure state of the eye mask, and the bathing water cannot be blocked from entering the eye, which may cause secondary damage to the eye. Therefore, we design a negative pressure eye mask for postoperative bathing of ophthalmology to solve the above problems. SUMMARY

[0004] In view of the problem that the negative pressure formed on the inner side of the existing eye mask is easy to cause irritation to the wound of the postoperative patient of ophthalmology, causing discomfort, and the rubber material at the bottom of the eye mask is easy to be worn out due to friction and other factors, thereby causing air leakage, which directly leads to the failure of the negative pressure state of the eye mask, and the bathing water cannot be blocked from entering the eye, the purpose of the present application is to provide a negative pressure eye mask for postoperative bathing of ophthalmology.

[0021] Compared with the prior art, the technical scheme provided by the application has at least the following beneficial effects:

[0022] In the above scheme, the inner side of the plastic ring is sucked to air by the negative pressure suction mechanism, so that the atmospheric pressure inside the first circular groove is less than the atmospheric pressure outside, so that a negative pressure state is formed inside the first circular groove, so that the eye cover is pressed tightly, so that the surgical patient can be bathed with the eye cover adhering to the eyes, thereby providing stable and reliable eye protection for postoperative bathing, significantly reducing the risk of infection or irritation caused by bath water infiltration, and thereby improving the overall practicality of the device.

[0023] By means of the isolation plate, the first circular groove is divided into multiple regions, and under the action of the elastic film, the air of the region that leaks cannot flow into other regions, so that other regions always maintain a negative pressure state, so that the eye cover can always be tightly adhered to the skin around the eyes, avoiding the "overall negative pressure collapse" caused by local air leakage, ensuring that most regions of the eye cover are tightly adhered to the skin around the eyes, and fundamentally solving the fatal defect of the traditional negative pressure eye cover "one damaged all", thereby improving the protection capability of the device and significantly improving the durability and adaptability of the device in actual use.

[0024] By means of the third circular groove, the inner side of the first air bag is blown, so that the first air bag is inflated, so that the first air bag can be squeezed in accordance with the face of the person, thereby solving the problem of "rigid adhesion and easy gap" of the traditional single negative pressure suction, reducing the risk of water infiltration to a lower level, and at the same time, the face shapes of different patients are significantly different, and the fixed size of the traditional eye cover is easy to cause sealing failure due to "incompatible adhesion", and after inflation, the skin is adhered with "elastic pressure", which can disperse local stress and reduce the stimulation to the sensitive area around the eyes, compared with the extrusion of the traditional hard edge.

[0025] By rotating the defogging mechanism, the spur gear is driven to rotate, thereby driving the rotating rod to rotate, thereby wiping the water vapor on the inner side of the eye patch, when the patient releases the squeezing of the second air bag, at this time, under the action of the compression spring, the driving shaft is pushed to reset, thereby making the rotating rod reset, so that when the patient squeezes back and forth, the rotating rod can rotate back and forth, thereby wiping the inner side of the eye patch back and forth, thereby effectively removing the water vapor on the inner side of the eye patch, ensuring clear vision, thereby facilitating the patient to clean the body, effectively solving the problem that blurred vision hinders bathing, thereby improving the overall practicality of the device.

[0026] By setting the squeezing water removal unit, the second air bag is continuously squeezed, so that the inner side of the rubber strip is continuously raised and reset, so that when water enters due to wear on one side of the rubber strip, the water inside the rubber strip can be pushed out to the outside when the rubber strip is raised, thereby preventing water from accumulating inside the rubber strip, thereby actively removing the accumulated water inside the rubber strip, cutting off the conduction chain of "accumulated water→penetration into the eye patch" from the source, significantly reducing the risk of water penetration, thereby improving the overall practicality of the device.

[0044] As shown in Figures 1 to 8 The embodiment of the present application provides an eye postoperative bathing water-proof negative pressure eyecup, which comprises an eyecup 1, one side of the eyecup 1 is provided with a contour matched with the periphery of eyes, and a plastic ring 2 is fixedly connected, an outer wall of the plastic ring 2 forms a first circular groove 5, rubber strips 3 are fixedly connected to two side edges of the plastic ring 2, the plastic ring 2 is provided with a first ring groove 12 extending along a direction, and a plurality of second circular grooves 13 are formed in the plastic ring 2 and communicated with the first circular groove 5 and the first ring groove 12.

[0045] A negative pressure adsorption mechanism, the negative pressure adsorption mechanism comprises a double-way diaphragm pump 10, an input end of the double-way diaphragm pump 10 is fixedly connected with a first connecting pipe 11, and one end of the first connecting pipe 11 penetrates to the inner side of the plastic ring 2 and is fixedly connected with a gas outlet of the first ring groove 12.

[0046] A rotating defogging mechanism, the rotating defogging mechanism is arranged on the inner side of the eyecup 1 and is used for removing water mist attached to the inner side of the eyecup 1.

[0047] After the double-way diaphragm pump 10 is started, air in the first ring groove 12 in the plastic ring 2 is extracted through the first connecting pipe 11, the air is extracted from the first circular groove 5 through the second circular groove 13, and negative pressure is formed in the first circular groove 5.

[0048] Under the action of the negative pressure, the rubber strips 3 on the two sides of the plastic ring 2 are closely attached to the skin around the eyes, and the negative pressure state of the first circular groove 5 further reinforces the attachment effect, so that the bathing water is prevented from penetrating from the edge of the eyecup 1 and irritation to the postoperative incision or infection is avoided.

[0049] When bathing, the inside of the eye cover 1 produces water mist due to temperature difference, affecting the line of sight, and the defogging mechanism is rotated to remove the water mist attached to the inside of the eye cover 1, quickly restoring a clear field of view, facilitating normal bathing operation of the patient, and without the need to frequently remove the eye cover 1 to interrupt protection.

[0050] In the above scheme, the negative pressure suction mechanism is arranged to suck air on the inside of the plastic ring 2, so that the atmospheric pressure on the inside of the first circular groove 5 is less than the atmospheric pressure outside, so that a negative pressure state is formed on the inside of the first circular groove 5, so that the eye cover 1 is pressed tightly, so that the surgical patient can bathe with the eye cover 1 adhering to the eyes, thereby providing stable and reliable eye protection for postoperative bathing, significantly reducing the risk of infection or irritation caused by bath water infiltration, thereby improving the overall practicality of the device.

[0051] Optionally, a plurality of elastic films 14 are arranged on the inside of the second circular groove 13, and the inside of the first circular groove 5 is fixedly connected with a plurality of isolation plates 8.

[0052] The first circular groove 5 is divided into multiple areas by the isolation plates 8, and under the action of the elastic films 14, the air in the area where air leakage occurs cannot flow into other areas, so that the other areas always maintain a negative pressure state, so that the eye cover 1 can always be tightly attached to the skin around the eyes, avoiding the "overall negative pressure collapse" caused by local air leakage, ensuring that most areas of the eye cover 1 are tightly attached to the skin around the eyes, and fundamentally solving the fatal defect of the traditional negative pressure eye cover 1 "all or nothing", thereby improving the protection capability of the device and significantly improving the durability and adaptability of the device in actual use.

[0053] As shown in Figures 2 to 5 Optionally, the device further comprises a connecting portion 32 arranged between the eye cover 1 and the plastic ring 2, a fourth circular groove 29 is arranged on the inside of the connecting portion 32, a sixth connecting pipe 30 is fixedly connected to the output end of the bidirectional diaphragm pump 10, and one end of the sixth connecting pipe 30 is fixedly connected to the air inlet of the fourth circular groove 29. The connecting portion 32 can be used to fix the bidirectional diaphragm pump 10 and provide a channel for gas delivery. Specifically, the output end of the bidirectional diaphragm pump 10, the sixth connecting pipe 30, and the fourth circular groove 29 are connected in sequence. The fourth circular groove 29 is used to output the gas in the bidirectional diaphragm pump 10.

[0054] Further, the plastic ring 2 has a second ring groove 18 extending in the extension direction; the inside of the plastic ring 2 is provided with a second mounting groove 7, the inside of the rubber strip 3 is provided with a first mounting groove 6, the first mounting groove 6 communicates with the second mounting groove 7, and a first air bag 9 is mounted in the first mounting groove 6 and the second mounting groove 7; a plurality of third circular grooves 15 are arranged in the plastic ring 2, and the first air bag 9, the third circular grooves 15, and the second ring groove 18 are sequentially connected in communication.

[0055] By setting the third circular groove 15, the inside of the first air bag 9 is blown, so that the first air bag 9 is inflated, so that the first air bag 9 can be squeezed in accordance with the human face, thereby solving the problem of "rigid fitting and easy gap" of the traditional single negative pressure adsorption, reducing the risk of water seepage to a lower level, while the face shape of different patients is significantly different, and the fixed size of the traditional eye mask 1 is easy to cause sealing failure due to "fitting mismatch", and after inflation, it is "elastic pressure" to fit the skin, compared with the traditional hard edge extrusion, it can disperse the local stress and reduce the stimulation to the sensitive area around the eyes.

[0056] Further, the bidirectional diaphragm pump 10 is controlled by a PLC (Programmable Logic Controller), which can control the intermittent start of the bidirectional diaphragm pump 10. When the surgical patient needs to take a bath, the surgical patient can wear the eye mask 1 to the face to fit the skin around the eyes, and then the PLC controls the bidirectional diaphragm pump 10 to start, thereby driving the input end of the bidirectional diaphragm pump 10 to suck air to the inside of the plastic ring 2, so that the atmospheric pressure inside the first circular groove 5 is less than the atmospheric pressure outside, thereby forming a negative pressure state inside the first circular groove 5, thereby pressing the eye mask 1, so that the surgical patient's bathing eye mask 1 can be fitted with the skin around the eyes, thereby providing stable and reliable eye protection for postoperative bathing, significantly reducing the risk of infection or irritation caused by bath water seepage, thereby improving the overall practicality of the device.

[0057] At the same time, when the eye mask 1 and the eyes are tightly fitted, due to the long-term contact of the outside rubber strip 3 with water during use, it is easy to cause wear, thereby causing air leakage, and when the rubber strip 3 leaks, at this time, due to the multiple isolation plates 8 dividing the first circular groove 5 into multiple areas, and under the action of the elastic film 14, the air in the area that leaks cannot flow into other areas, thereby making other areas always maintain a negative pressure state, so that the eye mask can always be tightly fitted with the skin around the eyes, avoiding the "overall negative pressure collapse" caused by local air leakage, ensuring that most areas of the eye mask are tightly fitted with the skin around the eyes, and fundamentally solving the fatal defect of the traditional negative pressure eye mask "one loss leads to all losses", thereby improving the protection ability of the device and significantly improving the durability and adaptability of the device in actual use.

[0058] As Figures 2 to 5As shown, further, the third circular groove 15 is provided with a second connecting pipe 16 at the air outlet, and one end of the second connecting pipe 16 is installed at the air inlet of the first air bag 9; the driving assembly further comprises a fifth connecting pipe 25 installed between the air inlets of the two connecting seats 21, and the eyeshade 1 is fixedly connected with a second air bag 22 on one side, the inner side of the second air bag 22 is provided with a third air bag 23, and the fourth connecting pipe 24 is installed at the air outlet of the third air bag 23 and penetrates to the outer side of the second air bag 22 and is fixedly connected with the fifth connecting pipe 25, and the inner side of the plastic ring 2 is provided with a squeezing water removal unit.

[0059] The two sides of the first air bag 9 are fixedly connected with the rubber strips 3 respectively, and the end of the first air bag 9 is not fixed with other parts, so that the end of the first air bag 9 extends when the first air bag 9 expands.

[0060] When the PLC controls the bidirectional diaphragm pump 10 to start, the inner side of the plastic ring 2 is sucked to air, at this time the output end of the bidirectional diaphragm pump 10 blows air to the inner side of the first air bag 9, so that the first air bag 9 expands, so that the first air bag 9 can conform to the face of the person and be squeezed, thereby solving the problem of "rigid fitting and easy gap" of the traditional single negative pressure adsorption, reducing the risk of water seepage to a lower level, and the face shape of different patients is significantly different, and the fixed size of the traditional eyeshade is easy to cause sealing failure due to "fitting mismatch", and after inflation, the skin is matched with "elastic pressure", compared with the traditional hard edge squeezing, the local stress can be dispersed, and the stimulation to the sensitive area around the eyes is reduced.

[0061] As shown in the figure, Figures 3 to 6 The rotating defogging mechanism comprises a rectangular groove 33 opened in the inner side of the eyeshade 1, two rotating shafts 19 are rotatably connected to the inner side of the rectangular groove 33, and one rotating strip 4 is fixedly connected to the top of the eyeshade 1 through the two rotating shafts 19 penetrating the top of the eyeshade 1; the rotating defogging mechanism further comprises two connecting seats 21 fixedly connected to the inner side of the second ring groove 18, a limiting sliding groove 26 is opened in the inner side of each connecting seat 21, a driving shaft 27 is slidably connected to the inner side of the limiting sliding groove 26, a compression spring 31 is installed between the inner side of the limiting sliding groove 26 and the driving shaft 27, and a driving assembly is arranged on one side of the rotating shaft 19; the driving assembly comprises a straight gear rack 28 fixedly connected to the other end of the driving shaft 27, a straight gear 20 is fixedly connected to the outer wall of the rotating shaft 19, and the straight gear 20 is engaged with the straight gear rack 28.

[0062] When water vapor appears on the inner side of the eyeshade 1, so that the patient cannot see the outside, the patient can squeeze the second air bag 22 back and forth with his hand. When the patient squeezes the second air bag 22, the air inside the third air bag 23 is squeezed into the inner side of the limiting sliding groove 26 under the action of the force of the patient, so as to push the driving shaft 27 to move in the direction of the fourth circular groove 29, drive the straight rack 28 to move, drive the straight gear 20 to rotate, drive the rotating bar 4 to rotate, and wipe the water vapor on the inner side of the eyeshade 1. When the patient releases the squeezing of the second air bag 22, the driving shaft 27 is reset under the action of the compression spring 31, so that the rotating bar 4 is reset. When the patient squeezes back and forth, the rotating bar 4 can rotate back and forth, so as to wipe the inner side of the eyeshade 1 back and forth, effectively remove the water vapor on the inner side of the eyeshade 1, ensure clear vision, and facilitate the patient to clean the body. The problem of blurred vision hindering bathing is effectively solved, and the overall practicability of the device is improved.

[0063] By rotating the defogging mechanism, the straight gear 20 is driven to rotate, thereby driving the rotating bar 4 to rotate, so as to wipe the water vapor on the inner side of the eyeshade 1. When the patient releases the squeezing of the second air bag 22, the driving shaft 27 is reset under the action of the compression spring 31, so that the rotating bar 4 is reset. When the patient squeezes back and forth, the rotating bar 4 can rotate back and forth, so as to wipe the inner side of the eyeshade 1 back and forth, effectively remove the water vapor on the inner side of the eyeshade 1, ensure clear vision, and facilitate the patient to clean the body. The problem of blurred vision hindering bathing is effectively solved, and the overall practicability of the device is improved.

[0064] As shown in Figures 5 to 8 , the water squeezing and removing unit includes a third connecting pipe 17 installed at the air inlet of the second mounting groove 7, and one end of the third connecting pipe 17 penetrates to the outside of the plastic ring 2 and is fixedly connected with the second air bag 22.

[0065] When the patient squeezes the second air bag 22, the air inside the second air bag 22 is squeezed into the inside of the first mounting groove 6 and the second mounting groove 7 under the action of the patient's force, thereby squeezing the rubber strip 3, pushing the rubber strip 3 to stretch upwards, and causing the rubber strip 3 to bulge. When the patient releases the squeezing of the second air bag 22, the rubber strip 3 returns to the original state. Therefore, the patient continuously squeezes the second air bag 22, so that the inside of the rubber strip 3 continuously bulges and returns. When the rubber strip 3 is worn on one side and water enters, the water inside the rubber strip 3 can be pushed out to the outside when the rubber strip 3 bulges, thereby preventing water from accumulating inside the rubber strip 3, actively removing the accumulated water inside the rubber strip 3, cutting off the conduction chain of "accumulated water -> seepage into the eyecup", significantly reducing the risk of water seepage, and improving the overall practicality of the device.

[0066] By setting the squeezing water removal unit, the second air bag 22 is continuously squeezed, so that the inside of the rubber strip 3 continuously bulges and returns. When the rubber strip 3 is worn on one side and water enters, the water inside the rubber strip 3 can be pushed out to the outside when the rubber strip 3 bulges, thereby preventing water from accumulating inside the rubber strip 3, actively removing the accumulated water inside the rubber strip 3, cutting off the conduction chain of "accumulated water -> seepage into the eyecup 1", significantly reducing the risk of water seepage, and improving the overall practicality of the device.
