Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a decompression patch for a non-invasive ventilator mask. Background Art
[0002] Non-invasive ventilators are clinically used to treat sleep apnea syndrome and related diseases. These diseases cause decreased blood oxygen saturation, increased sympathetic nerve tension, decreased parasympathetic nerve tension, increased blood carbon dioxide concentration, decreased pH value, and increased negative pressure in the chest, which seriously affect the functions of various important organs, especially brain function and cardiovascular function. The contact surface between the ventilator mask and the nose is a thin silicone sheet. The skin on the bridge of the nose and the sides of the nose of patients who use ventilators for a long time is under long-term pressure, which can easily cause local blood circulation disorders and pressure sores. The stuffiness caused by long-term wearing can easily cause discomfort to patients.
[0003] In order to avoid long-term pressure on the skin on both sides of the patient's nose bridge and nose wings, which may cause local blood circulation disorders and pressure sores, and the stuffiness caused by long-term wearing may easily cause discomfort to the patient, the Chinese utility model application number 202122476453.X proposes a protective patch for a non-invasive ventilator mask with good decompression effect, which belongs to the field of medical devices. A protective patch for a non-invasive ventilator mask with good decompression effect, including a fitting layer, the fitting layer includes an inner connecting layer, a dressing layer and an adhesion layer fixed to each other, an installation layer is provided on the upper side of the fitting layer, the installation layer includes an outer connecting layer and a fixing layer, and an extension layer is provided on the upper end of the inner connecting layer for plugging with the outer connecting layer; the utility model can enhance the fixing effect between the device and the mask; the existing problems are:
[0004] Due to the position of the facial features, general masks directly cover the mouth and nose when in use, and the mouth, nose and face need to be stably fitted through a corresponding arc structure. However, when the existing pressure-reducing stickers for non-invasive ventilator masks are in use, their overall structure is mostly a flat curved surface, which cannot fit the patient's facial features well to achieve a stable fit. Moreover, as a mask sticker layer, the use of a matching structure is likely to increase the facial pressure of the patient when wearing the mask, and cannot achieve a good pressure-reducing effect. Utility Model Content
[0005] In view of the defects in the prior art, the utility model provides a decompression patch for a non-invasive ventilator mask, which has a simple overall structure and can achieve stable fitting according to the positions of the facial features, while effectively reducing the pressure on the corresponding positions of the patient's face when wearing it.
[0006] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0008] Furthermore, the bottom raised layer is arranged along the bottom arc-shaped raised portion of the main body of the pasting layer, and the bottom raised layer is arranged as a strip-shaped raised layer as a whole, and is arranged in a "C" shape as a whole.
[0009] Furthermore, the bottom raised layer is configured as a mesh silicone layer.
[0010] Furthermore, two groups of first support layers are provided, which are located on both sides of the surface of the layer body and at the same time located at the arc-shaped transition position on the front side of the layer body.
[0011] Furthermore, the first supporting layer is provided in an arch-bridge-like protrusion, and the connection position between the first supporting layer and the surface of the main body of the pasting layer is provided in a curved transition. The first supporting layer is hollow inside and is provided as a silicone layer as a whole.
[0012] Furthermore, the first contact layer is configured as a thin layer of silicone, the second contact layer is configured as a hemispherical silicone layer with through holes on the surface, and multiple groups of the second contact layer are protrudingly arranged along the surface of the first contact layer.
