AI Technical Summary
When used, nasal oxygen tubes are fixed by hanging them on the patient's ears, which causes pressure on the face and auricle. Prolonged use can easily lead to pressure sores.
A nasal oxygen cannula pad has been designed, including a protective plate, a fixing member, and a flexible pad. The protective plate has a through groove for embedding the nasal oxygen cannula, the fixing member is connected by Velcro, the flexible pad fits the cheek or ear area, and the strip pad is used to distribute pressure.
It effectively reduces the risk of pressure sores in the cheek and ear areas, improves patient comfort, and the connection between the nasal oxygen tube and the pad is convenient and avoids damage.

Abstract
Claims
1. A nasal cannula for use with a nasal oxygen cannula, characterized in that, To provide padding for the cheek and / or auricular regions of patients using nasal oxygen tubes, thereby preventing pressure sores caused by prolonged direct pressure from the nasal oxygen tubes on the cheek and / or auricular regions, including: The protective plate is shaped to fit the patient's cheek area or auricle area. One side of the plate has a through groove that runs through both sides, which is used to embed the body of the nasal oxygen tube. The side of the protective plate with the through groove is a Velcro-style textured surface or a needle-like surface. The fastener is a hook-and-loop fastener with a pin or loop surface corresponding to the side of the guard plate having the through slot. The fastener is directly or indirectly hook-and-loop bonded to the guard plate and at least covers a portion of the through slot. A flexible padding material is applied to the other side of the protective plate, and its shape matches the patient's cheek area or ear area.
2. The nasal cannula pad according to claim 1, characterized in that: wherein The width of the through groove is the same as the outer diameter of the nasal oxygen cannula.
3. The nasal cannula pad according to claim 1, characterized in that: wherein The width of the through groove is greater than the outer diameter of the nasal oxygen cannula.
4. The nasal cannula pad according to claim 1, characterized in that: wherein When the nasal cannula pad is used to provide cheek support for patients using nasal canns, the side of the pad closest to the patient's cheek is curved, and the side of the flexible pad closest to the patient's cheek is curved to fit the patient's cheek area.
5. The nasal cannula pad according to claim 1, characterized in that: wherein, When the nasal cannula pad is used to provide auricular support for patients using nasal cannulas, the pad includes an outer cover and an ear hook. The ear hook is shaped to match the patient's auricle. An embedding groove is formed between the ear hook plate and the outer cover plate to match the patient's auricle and allow it to be embedded. The flexible padding material is applied to the inner surface of the embedding groove and / or the area of the ear hook that fits against the patient's head.
6. A nasal cannula with a protective pad assembly, characterized by include: Two nasal cannula pads are nasal cannula pads as described in any one of claims 1 to 5, wherein the two nasal cannula pads are respectively used to provide padding for the cheek area and auricle area of the patient using the nasal cannula. and A strip-shaped pad is detachably connected to two of the nasal oxygen cannula pads, and the tube of the nasal oxygen cannula between the two nasal oxygen cannula pads presses against the area between the patient's cheek and auricle.
7. The nasal oxygen cannula pad assembly according to claim 6, characterized in that: wherein The material of the strip pad is any one or more of elastic stretchable silicone, latex, nitrile, or woven fibers.
8. The nasal cannula pad assembly according to claim 7, characterized in that: wherein The strip-shaped pad is wavy, and the stretching direction of the strip-shaped pad is the same as the length direction of the nasal oxygen cannula. The curved area of the wavy strip-shaped pad that protrudes towards the patient's face is designated as the pressure ulcer prevention area, and the curved area of the wavy strip-shaped pad that protrudes outward away from the patient's face is designated as the pressure covering area. The pressure ulcer prevention area and the pressure covering area are evenly spaced apart.
9. The nasal cannula pad assembly according to claim 8, characterized in that: wherein, The wavy strip-shaped pad has several through holes evenly distributed on it, and the through holes are located on the pressing part. The curved pressing portion forms an arc-shaped embedding space at the through hole. The nasal oxygen cannula is embedded in the embedded space formed by several through holes, and the strip-shaped pad is pressed onto the patient's face.
10. The nasal cannula pad assembly according to claim 6, characterized in that: wherein The nasal oxygen cannula pad and the strip pad are connected by snap-fit, magnetic connection or Velcro connection.
