[0018] The present invention will be further described below with reference to the embodiments.
[0019] As shown in the figure, a pressure-ulcer-preventing nasal oxygen tube is fabricated based on an existing nasal oxygen tube. The existing nasal oxygen tube includes a nasal plug 1, an oxygen tube 2, and an elastic band 3. The oxygen tube 2 connects to the nasal plug 1, and the elastic band 3 is installed on both sides of the nasal plug 1, clipped to the ears or around the back of the head. In this embodiment, a nasal mask 4 is directly connected and installed to the nasal plug 1, and the elastic band 3 is divided into a nasal wing strap 31 and a nasal bridge strap 32. A head covering 5 is also added. The nasal mask 4 is composed of a left nasal wing frame 41, a left nasal bridge frame 42, a nose tip clip 43, a right nasal bridge frame 44, and a right nasal wing frame 45, which are sequentially generated and connected. The left nasal wing frame 41 is directly connected to the left end of the nasal plug 1, and the right nasal wing frame 45 is directly connected to the right end of the nasal plug 1, forming an integrated nasal plug and nasal mask structure 6. Both the nasal plug 1 and the nasal mask 4 are made of plastic. Medical silicone pads are provided on the nasal plug 1 and nasal mask 4 at the positions where they contact the user's facial skin. This allows the nasal plug 1 to cover the nostrils and rest on the bridge of the nose, providing comfort and distributing pressure on the nostrils, reducing the likelihood of pressure sores. A flat, elastic band hole 7 is provided on each of the left nasal wing bracket 41, left nasal bridge bracket 42, right nasal bridge bracket 44, and right nasal wing bracket 45. The nasal wing strap 31 is divided into a left nasal wing strap 311.
[0020] The left and right nostril straps 311 and 312 are respectively installed on the elastic band holes 7 on the left and right nostril brackets 41 and 45; the nose bridge straps 32 are divided into left nose bridge straps 321 and right nose bridge straps 322, and are respectively installed on the elastic band holes 7 on the left and right nose bridge brackets 42 and 44; the elastic bands 3 are the left nostril strap 311, right nostril strap 312, and left nose bridge strap 321.
[0021] A cheek pad 8 is provided on the right nasal bridge strap 322 at the position where it fits against the patient's cheek skin. The head cover 5 includes an integrally connected top cover 51 and back cover 52. On both sides of the junction of the top cover 51 and back cover 52 are the left ear exposure position 53 and the right ear exposure position 54, respectively. The upper side of the left ear exposure position 53 is directly connected to the left nasal bridge strap 321, and the lower side of the left ear exposure position 53 is directly connected to the left nasal wing strap 311. The upper side of the right ear exposure position 54 is directly connected to the right nasal bridge strap 322, and the lower side of the right ear exposure position 54 is directly connected to the right nasal wing strap 312. Both the head cover 5 and the elastic band 3 are made of skin-friendly fabrics such as pure cotton cloth, gauze, or other materials. The elastic band 3 is further made by wrapping a sponge block with skin-friendly fabric. At the same time, dense ventilation holes are provided on both the head cover 5 and the elastic band 3. This makes up the pressure ulcer prevention nasal oxygen tube of this utility model.
[0022] To accommodate different patients and head shapes, the developers initially added an adjustment buckle to the elastic band to securely hold the nasal plug / nose mask structure 6 and the head cover 5 in place. However, in actual use, the adjustment buckle would compress the patient's face. Therefore, the nasal plug 1, nasal mask 4, head cover 5, and elastic band 3 were made into multiple models of different sizes to better accommodate different head shapes. Instead of using the adjustment buckle, the pressure on the face could be avoided.
