Description

Technical Field

[0001] This utility model relates to the field of nasal decompression dressing technology, specifically a nasal decompression dressing for intraoperative use. Background Technology

[0002] Pressure injuries are localized injuries to the skin and / or subcutaneous soft tissues caused by pressure or pressure combined with shear force. They are usually located at bony prominences and may also be related to medical devices or other objects. Medical device-related pressure injuries refer to pressure injuries caused by the use of medical devices used for diagnosis or treatment, and are one of the most common intraoperative pressure injuries. The operating room is the department that uses medical devices most extensively, and the prevention of pressure injuries during surgery has become a focus of research. The target population is often elderly patients, those with long operation times, and those who are thin. The key prevention sites are often bony prominences such as the sacrum, coccyx, heel, and scapula. There is less attention paid to younger patients, such as those undergoing thyroid surgery, and there are fewer preventive measures for pressure injuries to the nose. Because thyroid surgery is performed in the neck, the normal placement area of ​​the endotracheal tube after general anesthesia (either through the mouth or nose) will affect the surgical field. Therefore, medical devices such as endotracheal tubes are often raised to the forehead. Some tubes will compress the protruding tip and bridge of the nose. The skin of the nose is thin, the subcutaneous tissue is small, and the peripheral blood supply is limited, making it prone to pressure injuries. Meanwhile, other patients undergoing neck and maxillofacial surgeries have also experienced situations where medical instruments such as endotracheal tubes are raised to the forehead during surgery, and some of these tubes can compress the protruding tip and bridge of the nose. Due to the three-dimensional shape of the nose, there is currently no suitable foam dressing for protecting the nasal skin and relieving pressure. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an intraoperative nasal decompression dressing, which solves the problem that, due to the lack of subcutaneous tissue in the nose, if pressure injury to the nose is not effectively prevented during surgery, the resulting pressure injury often leads to severe damage, poor prognosis, and is prone to pigmentation, even affecting the patient's facial appearance.

[0004] This utility model provides the following technical solution: a nasal decompression dressing for intraoperative use, comprising a mesh-like adhesive foam dressing, a middle layer of decompression dressing bonded to the top of the mesh-like adhesive foam dressing, two buffer airbags symmetrically arranged on both sides of the mesh-like adhesive foam dressing, an inflation valve provided on the side of the buffer airbags, two facial fixation patches symmetrically arranged at the bottom of both sides of the middle layer of the decompression dressing, and a tracheal intubation support assembly provided at the top of the middle layer of the decompression dressing;

[0005] The endotracheal tube support assembly includes a top connector at the top of the middle layer of the decompression dressing. The top of the top connector has a connecting slot, and a connecting block is inserted into the connecting slot. The bottom end of the connecting block is inserted into the connecting slot. Two connecting springs are symmetrically arranged in the connecting slot. The bottom end of the connecting spring is connected to the bottom wall of the connecting slot, and the top end of the connecting spring is fixedly connected to the bottom of the connecting block. The top of the connecting block has a top mounting groove, and a limit support plate is provided in the top mounting groove.

[0006] Preferred technical solution 1: A rotating connecting rod is inserted through the middle of the limiting support plate, and the two ends of the rotating connecting rod are rotatably connected to the inner wall of the top mounting groove.

[0007] Preferred technical solution 2: The side of the facial fixation patch is in the shape of a semi-fan that can be pasted.

[0008] This solution increases the adhesive area of ​​the facial fixation patch, making it easier to apply to the patient's face. It uses an elastic hydrogel material with excellent fluidity and adhesion.

[0009] Preferred technical solution three: The bottom end of the top connecting seat is in an arc shape that facilitates connection.

[0010] This design makes the connection between the top connector and the middle layer of the pressure-reducing dressing more secure.

[0011] Preferred technical solution four: The limiting support plate is in an arc-shaped curved shape to facilitate support of the endotracheal tube.

[0012] This design allows the limiting support plate to more easily support the endotracheal tube. It is made of semi-circular hard silicone material and can be used as an external support for placing the endotracheal tube to prevent it from slipping out.

[0013] Preferred technical solution five: The internal filling of the middle layer of the pressure-reducing dressing is made of elastic hydrogel beads of varying sizes and uniformly distributed.

[0014] This solution effectively distributes the pressure on the nose, preventing continuous pressure on any single point.

[0015] Compared with the prior art, this utility model provides an intraoperative nasal decompression dressing, which has the following beneficial effects:

[0016] (1) This utility model provides a pressure-reducing dressing intermediate layer on a mesh-like adhesive foam dressing, and an endotracheal tube support assembly on top of the pressure-reducing dressing intermediate layer. The limiting support plate in the endotracheal tube support assembly can limit and support the endotracheal tube during the operation, and the connecting block at the bottom of the limiting support plate is inserted into the connecting slot. Two connecting springs are provided in the connecting slot, and the connecting springs can provide a certain buffer for the limiting support plate, so that the pressure of the endotracheal tube on the mesh-like adhesive foam dressing and the pressure-reducing dressing intermediate layer is effectively buffered. At the same time, the softness and support of the mesh-like adhesive foam dressing and the pressure-reducing dressing intermediate layer can provide more effective protective support for the patient's nose, effectively avoiding pressure damage to the patient's nose caused by the endotracheal tube during long-term surgery, and better protecting the nose.

[0017] (2) This utility model is designed specifically for preventing pressure injuries to the nose, conforms to the physiological morphology and structure of the nose, has good conformability, is easy to apply, and is convenient for clinical use. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A nasal decompression dressing for intraoperative use, comprising a mesh-like adhesive foam dressing 1, which has decompression and moisture-absorbing functions, and is shaped like a three-dimensional triangle, which can fit the nose well and avoid damage to the nose. The top of the mesh-like adhesive foam dressing 1 is bonded with a decompression dressing middle layer 2. Two cushioning airbags 3 are symmetrically arranged on both sides of the mesh-like adhesive foam dressing 1. An inflation valve 4 is arranged on the side of the cushioning airbag 3. Two facial fixation patches 5 are symmetrically arranged at the bottom of both sides of the decompression dressing middle layer 2. An endotracheal tube support component 6 is arranged at the top of the decompression dressing middle layer 2.

[0026] The endotracheal tube support assembly 6 includes a top connecting seat 601 disposed at the top of the middle layer 2 of the decompression dressing. The top of the top connecting seat 601 has a connecting slot 602. A connecting block 603 is inserted into the connecting slot 602. The bottom end of the connecting block 603 is inserted into the connecting slot 602. Two connecting springs 604 are symmetrically arranged in the connecting slot 602. The bottom end of the connecting spring 604 is connected to the bottom wall of the connecting slot 602. The top end of the connecting spring 604 is fixedly connected to the bottom of the connecting block 603. The top of the connecting block 603 has a top mounting groove 605. A limiting support plate 606 is disposed in the top mounting groove 605. A rotating connecting rod 607 is inserted through the middle of the limiting support plate 606. The two ends of the rotating connecting rod 607 are rotatably connected to the inner wall of the top mounting groove 605.

[0027] Example 2: The difference between this example and Example 1 is that the side of the face fixing patch 5 is a semi-fan shape that can be pasted.

[0028] This increases the adhesive area of ​​the facial fixation patch 5, making it easier to apply to the patient's face. It is made of elastic hydrogel material, which has excellent fluidity and adhesion.

[0029] Example 3: The difference between this example and Example 1 is that the bottom end of the top connecting seat 601 is an arc shape that facilitates connection.

[0030] This makes the connection between the top connector 601 and the middle layer 2 of the pressure-reducing dressing more secure.

[0031] Example 4: The difference between this example and Example 1 is that the limiting support plate 606 is in an arc-shaped bend that facilitates the support of the endotracheal tube.

[0032] The limiting support plate 606 makes it easier to support the endotracheal tube. It is made of semi-circular hard silicone material and can be used as an external support for placing the endotracheal tube to prevent it from slipping out.

[0033] Example 5: The internal filling of the middle layer 2 of the pressure-reducing dressing is made of elastic hydrogel beads 201 of varying sizes and uniformly distributed.

[0034] It can effectively distribute the pressure on the nose, preventing continuous pressure on a single point.

[0035] In this embodiment, since the nose lacks subcutaneous tissue, if pressure injury to the nose is not effectively prevented during surgery, the resulting pressure injury is often more severe, with a poorer prognosis. It is prone to pigmentation and may even affect the patient's facial appearance. Therefore, it is very necessary to design an intraoperative nasal decompression dressing to prevent pressure injury.

[0036] In summary, during specific implementation, when a patient undergoes anesthesia for neck or maxillofacial surgery, or when the endotracheal tube is raised to the forehead, medical staff first need to inflate the cushioning airbag 3 located on the side of the mesh-like adhesive foam dressing 1 with appropriate gas. This allows the cushioning airbag 3 to contact the side of the mesh-like adhesive foam dressing 1. Then, using the facial fixation patch 5, the device is attached to the side of the patient's nose, allowing the mesh-like adhesive foam dressing 1 to be fixed to the nose. Because the cushioning airbag 3 is inflated with appropriate gas, the contact between the facial fixation patch 5 and the mesh-like adhesive foam dressing 1 and the cushioning airbag 3 enhances the contact between the cushioning airbag 3 and the side of the mesh-like adhesive foam dressing 1, making the mesh-like adhesive foam dressing 1 fit the patient's nose more closely, thereby improving the stability of the mesh-like adhesive foam dressing 1 and the patient's nose.

[0037] Next, when it is necessary to provide limiting support through the limiting support plate 606 in the endotracheal tube support assembly 6, the bottom end of the limiting support plate 606 is rotatably connected to the connecting plug 603 through the rotating connecting rod 607. The bottom end of the connecting plug 603 is slidably inserted into the connecting slot 602 opened at the top of the top connecting seat 601, and two connecting springs 604 are symmetrically arranged in the connecting slot 602. Thus, the connecting springs 604 can provide a certain elastic support for the connecting plug 603, so that when the endotracheal tube moves or its own weight comes into contact with the limiting support plate 606, the rebound force of the connecting springs 604 can provide effective buffering.

[0038] This allows the endotracheal tube to be effectively supported, and the mesh-like adhesive foam dressing 1 and the pressure-reducing dressing intermediate layer 2 above the nose can provide a more comfortable user experience for the nose, so as to avoid the endotracheal tube directly squeezing the nose and causing pressure damage to the nose during the long surgical anesthesia process, thus better protecting the nose.

[0039] Although the embodiments disclosed in this utility model are as described above, the content described is merely for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
