Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a three-lumen two-balloon tube anti-pressure ulcer dressing. Background Technology

[0002] The three-lumen two-balloon tube is an important treatment for esophageal and gastric variceal bleeding, and its fixation effect directly affects the success rate of hemostasis. Current pain points in nursing care stem from the insufficient compatibility between existing pressure ulcer dressings and the characteristics of the three-lumen two-balloon tube. The following problems exist: the three-lumen two-balloon tube requires fixation through nasal traction, but the human nasal alar region has an irregular three-dimensional curved shape. Currently used square pressure ulcer dressings, due to their planar structure not matching the physiological shape of the nasal alar, are prone to edge lifting and wrinkling during application. When the patient breathes, swallows, or makes slight head movements, poorly fitted pressure ulcer dressings can shift, exposing the local protected area and losing their pressure-relieving effect.

[0003] Meanwhile, during the traction process of the three-lumen two-balloon tube, the pressure generated by the inflation of the gastric and esophageal balloons is concentrated and transmitted to the nasal fixation point through the tube. The buffer layer of the pressure ulcer dressing of conventional thickness is relatively thin and cannot effectively disperse this high-intensity pressure. Under prolonged pressure, the blood circulation of the nasal skin tissue is obstructed, which can easily lead to ischemic damage and pressure ulcers. In severe cases, it can even cause skin ulceration and infection, increasing the patient's pain and the difficulty of care. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a pressure ulcer dressing for three-lumen two-balloon tubes. It solves the problems of poor fit, weak pressure ulcer prevention effect, and lack of tube limiting when used with existing pressure ulcer dressings for three-lumen two-balloon tubes, thereby improving patient comfort, reducing the risk of pressure ulcers, and ensuring treatment safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pressure ulcer dressing for a three-lumen two-balloon tube includes a base fabric layer, an anti-pressure block on the base fabric layer, a limiting groove on the anti-pressure block for restricting the movement of the three-lumen two-balloon tube, an adhesive layer on the base fabric layer, and a dustproof paper covering the adhesive layer.

[0006] Preferably, the anti-pressure block includes an extension end integrally formed with the anti-pressure block, the extension end being able to extend into the user's nostril, the shape and size of the extension end being designed to allow it to extend into the user's nostril, thereby improving the anti-pressure effect of the anti-pressure block.

[0007] Preferably, the extended end is symmetrically provided with fitting grooves that adapt to the edge of the nasal wing. The shape of the fitting groove matches the contour of the nasal wing edge, which can closely fit the edge of the nasal wing, further enhancing the fit between the patch and the nose, and reducing local pressure and discomfort caused by poor fit.

[0008] Preferably, the pressure relief block has a thickened section at the position outside the nostril, and the thickness of the thickened section is greater than that of other areas of the pressure relief block. Since the part of the three-lumen two-balloon tube outside the nostril exerts greater pressure on the nasal skin, the thickened section can better buffer and disperse this pressure, enhance the protection of the local skin, and improve the effect of preventing pressure sores.

[0009] Preferably, there are three limiting grooves, each corresponding to one of the three pipes of the three-lumen two-bladder tube. The three limiting grooves can limit the movement of the three pipes of the three-lumen two-bladder tube, effectively reducing the displacement of the pipes caused by various factors during traction.

[0010] Preferably, the adhesive layer is applied to the side of the base fabric layer facing the skin, using a breathable and hypoallergenic medical adhesive material. The breathability ensures that the skin can breathe normally, reducing problems such as stuffiness and dampness caused by prolonged coverage; the hypoallergenic properties reduce the risk of skin allergies, allowing the patch to be safely applied to the skin of the nose.

[0011] Preferably, the dustproof paper covers the outside of the adhesive layer and is paper or plastic film coated with an anti-sticking substance. During storage and transportation, the dustproof paper can effectively prevent the adhesive layer from being contaminated, ensure that the adhesive layer has good adhesion when used, and ensure that the application can be used normally.

[0012] Preferably, the two ends of the base fabric layer without anti-pressure blocks are provided with bendable fitting ends. The fitting ends can be bent according to the actual shape of the patient's nasal wings, making it easy to fit the patient's nasal wings, further improving the overall stability and comfort of the dressing, and reducing the phenomenon of dressing shifting during use.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model significantly improves the protection and fixation effect through the innovative design of the anti-pressure block. The one-piece molded extension end of the anti-pressure block can be inserted into the nostril. With the symmetrically set fitting grooves on the extension end, it can accurately fit the contour of the nasal wing edge and closely fit the irregular curved surface of the nose. It effectively solves the problems of poor fit and easy displacement of traditional square pressure sore patches, and reduces local pressure and discomfort. Furthermore, the thickened part of the anti-pressure block outside the nostril can specifically buffer the high pressure during the traction of the three-lumen two-balloon tube, disperse the pressure and improve local blood circulation, reduce the risk of pressure sores, and the three limiting grooves correspond to the three tubes of the three-lumen two-balloon tube to achieve precise positioning, reduce tube displacement, ensure the stability of the pressure hemostasis position, and improve the treatment effect.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0019] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0021] Please seeFigures 1-4 A pressure ulcer dressing for a three-lumen two-balloon tube includes a base fabric layer 1, a pressure-resistant block 2 on the base fabric layer 1, a limiting groove 22 on the pressure-resistant block 2 for restricting the movement of the three-lumen two-balloon tube, an adhesive layer 3 on the base fabric layer 1, and a dustproof paper 4 covering the adhesive layer 3.

[0022] The anti-pressure block 2 includes an extension end 21 integrally formed with the anti-pressure block 2. The extension end 21 can be inserted into the user's nostril. The shape and size design of the extension end 21 enable it to be inserted into the user's nostril to improve the anti-pressure effect of the anti-pressure block 2.

[0023] The extension end 21 is symmetrically provided with fitting grooves 211 that are adapted to the edge of the nose. The shape of the fitting grooves 211 matches the contour of the edge of the nose, which can fit tightly to the edge of the nose, further enhancing the fit between the patch and the nose, and reducing local pressure and discomfort caused by poor fit.

[0024] The pressure relief block 2 has a thickened part 23 located outside the nostril. The thickness of the thickened part 23 is greater than that of other areas of the pressure relief block 2. Since the part of the three-lumen two-balloon tube outside the nostril puts greater pressure on the nasal skin, the thickened part 23 can better buffer and disperse this pressure, enhance the protection of the local skin, and improve the effect of preventing pressure sores.

[0025] There are three limiting grooves 22, which correspond to the three pipes of the three-lumen two-bladder tube respectively. The three limiting grooves 22 can limit the three pipes of the three-lumen two-bladder tube, effectively reducing the displacement of the pipes caused by various factors during traction.

[0026] The adhesive layer 3 is applied to the skin-facing side of the base fabric layer 1. It uses breathable and hypoallergenic medical adhesive material. The breathability ensures that the skin can breathe normally, reducing problems such as stuffiness and dampness caused by prolonged coverage. The hypoallergenic properties reduce the risk of skin allergies, allowing the patch to be safely applied to the skin of the nose.

[0027] Dustproof paper 4 covers the outside of the adhesive layer 3. It is paper or plastic film coated with anti-sticking material. During storage and transportation, dustproof paper 4 can effectively prevent the adhesive layer 3 from being contaminated, ensure that the adhesive layer 3 has good adhesion when used, and ensure that the application can be used normally.

[0028] The base fabric layer 1 without the anti-pressure block 2 has two bendable fitting ends 11 at both ends. The fitting ends 11 can be bent according to the actual shape of the patient's nasal wings, making it easy to fit the patient's nasal wings, further improving the overall stability and comfort of the dressing, and reducing the phenomenon of the dressing shifting during use.

[0029] During preparation, the base fabric layer 1 is made of a suitable medical textile material, such as a breathable non-woven fabric, and is cut into a basic shape that conforms to the size and shape of the nasal wing area. When making the anti-pressure block 2, a material with cushioning properties, such as high-density sponge or silicone, can be used. The anti-pressure block 2 is fixedly connected to the base fabric layer 1 through molding and other processes to ensure that the integrally formed extension end 21 is firmly connected to the anti-pressure block 2. Three limiting grooves 22 are opened on the anti-pressure block 2 corresponding to the position of the three-lumen two-balloon tube. A fitting groove 211 adapted to the edge of the nasal wing is symmetrically processed on the extension end 21. The anti-pressure block 2 is thickened at the position outside the nostril to form a thickened part 23. The side of the base fabric layer 1 facing the skin is evenly coated with a breathable and hypoallergenic medical adhesive material to form an adhesive layer 3. Paper or plastic film coated with an anti-adhesive substance is covered on the outside of the adhesive layer 3 to make a dustproof paper 4, thus completing the preparation of the dressing. When using the patch, medical staff first clean the patient's nasal skin to ensure it is dry and clean. Carefully peel off the dustproof paper 4 from the edge of the patch, taking care to avoid contaminating the adhesive layer 3. Gently insert the extended end 21 of the patch into the patient's nostril, so that the fitting groove 211 is precisely fitted with the edge of the nasal wing. At the same time, bend the fitting end 11 of the base fabric layer 1 and attach it to the nasal wing. The three tubes of the three-lumen two-balloon tube are respectively located in the three limiting grooves 22 of the anti-pressure block 2, thereby limiting the three tubes on the three-lumen two-balloon tube to a certain extent.

[0030] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
