Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nasal high-flow protective shield for preventing pressure injury. Background Technology

[0002] High-flow nasal cannula (HFNC) is a form of non-invasive respiratory support that rapidly improves oxygenation. It delivers a continuous flow of high-flow-rate oxygen via a high-flow nasal cannula, with adjustable and relatively constant oxygen concentration, temperature, and humidity. During treatment, a protective mask is required; however, the mask's straps can cause pressure and friction on the patient's skin, leading to skin damage and discomfort.

[0003] To address the aforementioned issues, Chinese patent application CN202410967847.0 discloses a protective device for a high-flow nasal strap. This device ensures comfort during wear by incorporating a hollow foam pearl cotton layer on the strap and providing several equally spaced ventilation holes on the surfaces of both the front and rear elastic fabric strips.

[0004] However, the above solutions cannot effectively protect the auricle of different patients, and prolonged wear will still cause significant pressure and friction damage to the upper part of the auricle. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a nasal high-flow protective shield to prevent pressure injury, which can reduce the pressure and friction of the fixing strap on the patient's auricle when the patient wears it for a long time, thereby improving the wearing comfort.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a nasal high-flow nasal mask for preventing pressure injury, comprising a mask body, fixed straps on both sides of the mask body, a connecting part on the outer side of the mask body for connecting a functional catheter, and a fixing device at the end of the fixed straps; a protective sleeve that fits with the patient's auricle is also provided on the fixed straps, and the protective sleeve is slidably connected to the fixed straps.

[0008] The protective sleeve includes an upper sleeve and a lower sleeve. The upper sleeve has a sliding hole that mates with the fixing strap, and the sliding hole and the fixing strap are slidably connected. A rigid ring that mates with the fixing strap is also fixed inside the sliding hole to facilitate the sliding of the fixing strap. The lower sleeve has a snap-fit ​​block fixed on one side near the upper sleeve, and a C-shaped part that mates with the auricle on the other side. The C-shaped part has a ventilation groove, and several ventilation holes are evenly distributed at the bottom of the ventilation groove to ensure dryness at the clamping point and improve comfort. The upper sleeve has a snap-fit ​​groove on the side near the lower sleeve that mates with the snap-fit ​​block, and the snap-fit ​​block and the snap-fit ​​groove are snap-fit ​​connected. The upper sleeve has an integrally formed fitting part on the side near the human skin, and the fitting part extends along the fixing strap. The upper sleeve and the lower sleeve are made of elastic material, and the surfaces of the upper sleeve and the lower sleeve are made of a skin-friendly layer.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention features a protective sleeve that can move along a fixed strap, which protects the patient's auricle, prevents excessive pressure and friction damage, and improves the patient's comfort when wearing the device. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] As shown in the figure, this utility model provides a nasal high-flow nasal mask for preventing pressure injury, including a mask body 1, with a connecting part 11 on the outer side of the mask body 1 for connecting the functional catheter; fixing straps 2 are fixed on both sides of the mask body 1, and fixing devices are also provided at the tail of the fixing straps 2, such as Velcro or buckles, to wear the mask body 1 on the patient's face; a protective sleeve 3 is also provided on the fixing strap 2 to fit the patient's auricle, and the protective sleeve 3 is slidably connected to the fixing strap 2. In this way, for different patients, the protective sleeve 3 can be slid along the fixing strap 2 to the patient's auricle. At the same time, since the protective sleeve 3 and the fixing strap 2 are slidably connected, the fixing strap 2 will not move when the patient turns over after wearing the mask, so that there will be no relative friction on the auricle, thereby preventing damage to the auricle from the fixing strap.

[0023] Based on the above overall scheme, the protective sleeve 3 includes an upper sleeve 31 and a lower sleeve 32. The upper sleeve 31 has a sliding hole 311 that cooperates with the fixing band 2. The sliding hole 311 and the fixing band 2 are slidably connected. In order to facilitate the sliding of the fixing band 2 in the sliding hole 311, a rigid ring 313 that cooperates with the fixing band 2 is also fixed in the sliding hole 311.

[0024] Considering that different patients have different ear sizes, and sometimes it is necessary to change the lower cover 32 accordingly, the lower cover 32 is fixed with a snap-fit ​​block 321 on the side near the upper cover 31, and a C-shaped part 322 that fits the ear on the other side for easy wearing. The upper cover 31 is provided with a snap-fit ​​groove 312 that fits the snap-fit ​​block 321 on the side near the lower cover 32. The snap-fit ​​block 321 and the snap-fit ​​groove 312 are snapped together; thus, the lower cover 32 can be easily changed.

[0025] In summary, when using the device, first put the main body 1 of the mask on the patient, and then use the fixing strap 2 to fix it. When fixing, first select the lower sleeve 32 and the upper sleeve 31 that fit the patient's auricle and combine them. Then move the protective sleeve 3 along the fixing strap to the upper part of the patient's auricle and clamp it. Then use the fixing device to fix the fixing strap 2 to complete the wearing of the entire protective mask.

[0026] Preferably, to further reduce pressure damage, the upper sleeve 31 and the lower sleeve 32 are made of elastic material. The upper sleeve 31 can also be provided with an integrally molded fitting part on the side close to the human skin. The fitting part extends along the fixing band 2 (depending on the situation, not shown in the figure). The surface of the upper sleeve 31 and the lower sleeve 32 is made of skin-friendly layer. At the same time, the C-shaped part 322 is provided with a ventilation groove 3221, and a number of ventilation holes 3222 are evenly provided at the bottom of the ventilation groove 3221. In this way, after wearing, it can ensure that the contact area between the lower sleeve 32 and the auricle is dry, and improve the wearing comfort.

[0027] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
