Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an ophthalmic airbag pressure dressing. Background Technology

[0002] The skin and muscle layers around the eyes are thin and relatively sensitive. Postoperative bleeding is common after ophthalmic surgery, requiring pressure to reduce it. Furthermore, the recovery process after ophthalmic surgery is dynamic, with varying pressure requirements at different stages. For example, higher pressure is needed in the early stages of surgery to effectively stop bleeding and reduce swelling, while the pressure needs to be appropriately reduced as the wound heals.

[0003] Currently, routine eye surgery mainly relies on simple gauze bandages. The tightness of the bandage depends on the subjective experience of medical staff. If it is too loose, it cannot provide pressure to stop bleeding. If it is too tight, it may lead to poor blood circulation in the eye, causing tissue ischemia and hypoxia, and increasing the patient's pain.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0054] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality of" means two or more, unless otherwise explicitly defined.

[0056] Please see Figure 1 and Figure 3 This embodiment provides an ophthalmic balloon pressure dressing, which includes: a dressing body 100, a balloon compression component 200, and a pressure sensor 300. The balloon compression component 200 is connected to the dressing body 100 and is used to compress the dressing body 100 for hemostasis. The pressure sensor 300 is connected to the balloon compression component 200 and is used to monitor the pressure of the balloon compression component 200.

[0057] In this embodiment, the dressing body 100 can be adhered to the wound on the patient's eye. The airbag compression component 200 applies pressure to the eye to stop bleeding, and the pressure sensor 300 monitors the pressure of the airbag compression component 200, allowing for precise control of the applied pressure. For example, after ophthalmic surgery, the dressing body 100 can be adhered to the eye, and the airbag compression component 200 can be controlled to apply pressure to the dressing body 100 to achieve hemostasis. In the early stages of surgery, the airbag compression component 200 can be controlled to apply a first pressure to the eye, which can be understood as a higher pressure, thus facilitating hemostasis and reducing swelling. As the wound heals, the airbag compression component 200 can be controlled to apply a second pressure to the eye, which can be understood as a lower pressure, to further promote wound healing. The specific values ​​of the first and second pressures can be precisely controlled by the pressure sensor 300. It should be understood that both the first and second pressures are within the pressure range that the patient can tolerate, ensuring both hemostasis and patient comfort. If the patient experiences pressure pain in the eye, the pressure can be appropriately reduced.

[0058] It is understood that the pressure sensor 300 can be a flexible thin-film pressure sensor 300. The flexible thin-film pressure sensor 300 has the advantages of being thin, light, and flexible, and can conform to the skin around the eyes, which can improve the comfort of the patch body 100. The flexible thin-film pressure sensor 300 can be understood as existing technology, and the specific structure of the flexible thin-film pressure sensor 300 will not be described in detail.

[0059] Therefore, in this embodiment, the airbag compression component 200 is used to apply pressure to the eye wound to achieve hemostasis. At the same time, the pressure sensor 300 monitors the pressure and can precisely control the pressure to achieve phased pressure control, which is beneficial to the recovery of eye trauma.

[0060] Specifically, please refer to Figure 2 The airbag compression assembly 200 includes: an elastic base 210, an airbag portion 220, and an inflatable balloon 230. The elastic base 210 is connected to the dressing body 100. The airbag portion 220 is disposed on the elastic base 210. The inflatable balloon 230 is connected to the airbag portion 220. The inflatable balloon 230 is used to inflate and pressurize the airbag portion 220, and the inflatable balloon 230 is connected to the pressure sensor 300.

[0061] In this embodiment, the elastic base 210 is connected to the dressing body 100. The elastic base 210 is used to mount the airbag portion 220, which is connected to the inflatable balloon 230. It is understood that when the airbag portion 220 is inflated, it expands, thereby applying pressure to the dressing body 100 through the elastic base 210. The inflatable balloon 230 is used to inflate the airbag portion 220. For example, when pressure needs to be applied to the dressing body 100, the inflatable balloon 230 can be pressed, causing it to inflate and pressurize the airbag portion 220. The elastic base 210 facilitates the even application of pressure to various areas of the eye, achieving uniform pressure application.

[0062] Specifically, please refer to Figure 2 The elastic base 210 includes a sponge pad 211, one side of which is connected to the dressing body 100 and the other side is connected to the airbag part 220.

[0063] In this embodiment, the elastic base 210 can be made of a sponge pad 211. The sponge pad 211 is made of a porous, lightweight, and elastic material. The sponge pad 211 is located between the air bladder portion 220 and the dressing body 100. The air bladder portion 220 needs to apply pressure to the dressing body 100 through the sponge pad 211. On the one hand, the sponge pad 211 can help to evenly apply the pressure of the air bladder portion 220 during expansion to various areas of the eye. On the other hand, the sponge pad 211 has a cushioning property, which prevents the air bladder portion 220 from applying excessive pressure to the eye during expansion, thereby reducing patient pain and improving the comfort of using the dressing. A pressure sensor 300 can be provided on the side of the sponge pad 211 closest to the dressing body 100.

[0064] Specifically, please refer to Figure 3 The elastic base 210 includes a silicone pad 212 and a sponge pad 211. The silicone pad 212 is connected to the dressing body 100. The sponge pad 211 is disposed on the side of the silicone pad 212 away from the dressing body 100. An air bladder 220 is disposed on the side of the sponge pad 211 away from the silicone pad 212. A pressure sensor 300 is disposed between the silicone pad 212 and the sponge pad 211.

[0065] In this embodiment, the elastic base 210 includes two parts: a silicone pad layer 212 and a sponge pad layer 211. It can be understood that the patch body 100, the silicone pad layer 212, and the sponge pad layer 211 are stacked in sequence. That is, the airbag part 220 is connected to the patch body 100 in sequence through the sponge pad layer 211 and the silicone pad layer 212. The airbag part 220 can apply pressure evenly to the patch body 100 through the silicone pad layer 212 and the sponge pad layer 211. At the same time, the sponge pad layer 211 has a cushioning property, which can reduce the impact of the airbag part 220 on the eye during the expansion process. The silicone pad layer 212 can further reduce the impact of the airbag part 220, ensuring that the airbag part 220 applies pressure evenly and stably to the eye.

[0066] Specifically, please refer to Figure 2 The airbag section 220 includes: a plurality of airbag components 221 and a first conduit 222, the first conduit 222 being used to connect two adjacent airbag components 221, so that the plurality of airbag components 221 form an airbag network 223.

[0067] In this embodiment, the airbag part 220 includes a plurality of airbag components 221. It can be understood that the plurality of airbag components 221 are evenly distributed within the patch body 100, and the plurality of airbag components 221 are interconnected through the first conduit 222 to form an airbag network 223. The function of the airbag network 223 is to facilitate the even application of pressure from the plurality of airbag components 221 to various areas of the eye, and to avoid the airbag components 221 concentrating on applying pressure at a certain point in the eye. For example, if a single airbag is used, when the airbag is inflated, the airbag may concentrate on applying pressure at the middle of the eyeball, which may result in excessive pressure at the middle of the eyeball.

[0068] Specifically, please refer to Figure 2 The inflatable balloon 230 includes: a balloon body 231, a second conduit 232, and a control valve 233. The second conduit 232 is used to connect the balloon body 231 and the balloon part 220. The control valve 233 is disposed on the second conduit 232 and is used to control the air intake and exhaust of the second conduit 232.

[0069] In this embodiment, the balloon body 231 is used to inflate the airbag part 220, the second conduit 232 is used to connect the balloon body 231 and the airbag part 221, and the control valve 233 is disposed on the second conduit 232. The control valve 233 has a first state and a second state. When it is in the first state, the second conduit 232 is in the conducting state, that is, the balloon body 231 is connected to the airbag part 220, and the balloon body 231 can be pressed to inflate the airbag part 220. When it is in the second state, the second conduit 232 is in the disconnected state, and the airbag part 220 can be depressurized through the second conduit 232.

[0070] Specifically, please refer to Figure 2 and Figure 4 The dressing body 100 includes an adhesive portion 110 and a covering portion 120. The adhesive portion 110 is used to adhere to and connect with the patient's eye. The covering portion 120 is connected to the adhesive portion 110 and forms a hollow cavity with the adhesive portion 110.

[0071] In this embodiment, the adhesive portion 110 refers to the side that adheres to and contacts the skin, and the covering portion 120 is connected to the edge of the adhesive portion 110 and covers the adhesive portion 110. The connection between the adhesive portion 110 and the covering portion 120 can form a hollow cavity. The hollow cavity contains an airbag compression assembly 200. For example, the hollow cavity can contain a pressure sensor 300, a sponge pad 211, and an airbag network 223.

[0072] In one implementation, please refer to Figure 4 and Figure 6 The fitting part 110 includes: a first gauze base layer 111, a waterproof ring 112, and an adhesive part 113. The first gauze base layer 111 is used to fit and connect with the patient's eye. The waterproof ring 112 is disposed on the first gauze base layer 111.

The covering part 120 includes a second gauze base layer 121, which is connected to the first gauze base layer 111.

[0073] In this embodiment, the first gauze base layer 111 can be bonded to the patient's eye via the adhesive portion 113, and the first gauze base layer 111 is provided with a waterproof ring 112, which can prevent blood leakage and avoid affecting the adhesiveness of the adhesive portion 113. The first gauze base layer 111 and the second gauze base layer 121 are connected to form a hollow cavity, which can accommodate the airbag compression component 200.

[0074] Optionally, the first gauze base layer 111 includes anhydrous fusible fabric, which is used to adhere and connect to the patient's eye.

[0075] The waterproof ring 112 includes a silicone ring, which is disposed on the anhydrous imitation fabric; the adhesive part 113 includes a gel 115 disposed on the anhydrous imitation fabric and a release paper 116 connected to the gel 115; the second gauze base layer 121 includes a spunlace nonwoven fabric, which is connected to the anhydrous imitation fabric.

The silicone ring is soft and comfortable, and it prevents blood leakage, avoiding affecting the adhesiveness of the gel 115. The manufacturing process is simple and easy to implement.

[0077] In another implementation, please refer to Figure 5 and Figure 7 The bonding portion 110 includes a first gauze base layer 111 and a third gauze base layer 114 disposed around the first gauze base layer 111.
