Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a non-invasive mask pressure ulcer prevention patch. Background Art

[0002] Non-invasive ventilators have become an important means of respiratory support for the treatment of respiratory failure. In clinical use, especially in patients with emaciated faces, it is easy for non-invasive respiratory masks to fit poorly and leak air, resulting in low minute ventilation volume of patients and poor treatment effects. In order to closely fit and use non-invasive respiratory masks for a long time, skin erythema and breakage are likely to occur at pressure points such as both sides of the nose wings, the bridge of the nose, both zygomatic bones, and the mandible, and then medical device-related pressure ulcers will appear.

[0003] At present, the pressure ulcer prevention patch between the non-invasive respiratory mask and the patient's skin is a hydrocolloid dressing, which is a skin-friendly dressing mainly made of hydrophilic colloid. Although the hydrocolloid dressing can isolate the direct contact between the non-invasive respirator and the skin, the thickness of the hydrocolloid dressing is relatively thin, so its pressure ulcer prevention effect is limited, and when the hydrocolloid dressing is torn off, it will also cause problems such as skin pain and residual glue marks. Therefore, a non-invasive mask pressure ulcer prevention patch is proposed. Content of the Utility Model

[0004] The utility model is proposed to solve the shortcomings existing in the prior art, and provides a non-invasive mask pressure ulcer prevention patch.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a non-invasive mask pressure ulcer prevention patch, including a non-invasive mask body, a connection pressure groove is pressed at the edge of the non-invasive mask body, a hollow rubber ring is fixedly installed at the bottom of the connection pressure groove, and a decompression patch is fixedly installed at the bottom of the hollow rubber ring;

[0006] The decompression patch includes an upper decompression layer, and the upper decompression layer is fixedly connected with the hollow rubber ring. An assembly and disassembly component is installed at the bottom of the upper decompression layer, and a skin-friendly decompression layer is fixedly installed at the bottom of the assembly and disassembly component.

[0007] Further, the connection pressure groove includes an annular rubber strip, and the annular rubber strip is fixedly installed at the top of the hollow rubber ring. A connection groove matching the non-invasive mask body is opened at the top of the annular rubber strip. The setting of the connection groove is beneficial to pressing the edge of the non-invasive mask into the inner side of the annular rubber strip.

[0008] Further, a first extrusion pad is fixedly connected to one inner wall of the connection groove, a second extrusion pad is fixedly connected to the other inner wall of the connection groove, and both the first extrusion pad and the second extrusion pad are in contact with the non-invasive mask body, increasing the extrusion force between the annular rubber strip and the non-invasive mask body, making it not easy to fall off, thereby improving the fixing effect.

[0009] Furthermore, the disassembly and assembly component includes a hook surface of Velcro, and the hook surface of Velcro is fixedly installed at the bottom of the upper decompression layer. The bottom of the hook surface of Velcro adheres to a loop surface of Velcro, and the loop surface of Velcro is fixedly installed at the top of the skin-friendly decompression layer. The fixing speed of Velcro is very fast. As long as the loop surface of Velcro is covered on the hook surface of Velcro, it can be quickly fixed and can be used multiple times.

[0010] Furthermore, the material of the upper decompression layer is selected as a foam pad. The foam pad is made of foam material, has good elasticity and softness, and its softness can also well adapt to the facial curve of the human body, avoid pressing on the face, and help reduce facial fatigue.

[0011] Furthermore, the material of the skin-friendly decompression layer is selected as flannelette. Flannelette is a fabric made of fibers such as cotton, wool, and chemical fibers. Its characteristic is that fluff is woven on the surface of the fabric. The fluff of flannelette is soft and comfortable, does not bring a tingling feeling to people, has a very good skin-friendly effect, and also has a certain hygroscopicity to ensure the dryness of the area where the patient's face is pressed.

[0012] Furthermore, both the hollow rubber ring and the annular rubber strip are adhesively connected to the upper decompression layer. Adhesive connection can form a very reliable connection because it can fully fill the gap between the connection surfaces and form a solid fixing structure.

[0013] Advantages of the utility model:

[0014] When the utility model is in use, for this pressure ulcer prevention patch for a non-invasive face mask, through the arranged connection pressure groove, hollow rubber ring, upper decompression layer, disassembly and assembly component, and skin-friendly decompression layer, as a whole, when in use, it can be fixed on the non-invasive face mask body for use, without being adhesively attached to the facial skin of the patient. Therefore, problems such as skin pain and residual glue marks during removal can be avoided. At the same time, the whole adopts three-layer decompression, which can effectively prevent pressure injury to the face caused by long-term wearing of the non-invasive face mask. Moreover, after the hollow rubber ring is compressed, the gas inside it actively moves to the place with less pressure and quickly fills that place, thus ensuring the overall sealing performance.

[0015] When the utility model is in use, for this pressure ulcer prevention patch for a non-invasive face mask, through the arranged upper decompression layer, disassembly and assembly component, and skin-friendly decompression layer, the skin-friendly decompression layer can be conveniently disassembled for cleaning or replacement, improving the overall use effect.
