[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a high-flow nasal catheter oxygen inhalation fixing device. Background Art
[0002] The high-flow machine continuously provides patients with a high-flow (8-80L / min) inhaled gas treatment method with adjustable and relatively constant oxygen concentration (21%-100%), temperature (31-37°C) and humidity through a high-flow dedicated nasal cannula. It is a new type of oxygen therapy equipment and cannot improve the patient's ventilation ability. However, the high-flow respiratory humidification therapy device can treat patients with respiratory failure and significantly improve their vital signs. The high-flow respiratory humidification therapy device has a good effect in improving patients' PaO2 and SaO2.
[0003] When using a high-flow machine, you need to wear a high-flow nasal cannula. Compared with ordinary nasal cannula, high-flow nasal cannula is worn more tightly. Existing nasal cannula is simply fixed on the user's head with a nylon strap, which often causes discomfort or even pressure on the patient's face. This discomfort is especially obvious for patients who need to wear nasal cannula for a long time. In addition, it is not convenient and flexible for users to adjust the tightness of the fixing strap during wearing, and it cannot adapt to the head shape and face size of different patients, which further increases the patient's discomfort. Utility Model Content
[0004] In view of the above problems, the present application provides a high-flow machine nasal catheter oxygen inhalation fixing device, comprising two sheet-like air bags, the sheet-like air bags are symmetrically connected to the two sides of the nasal catheter, and the side of each sheet-like air bag away from the nasal catheter is connected to the connecting part;
[0005] A connecting portion, the connecting portion being used to detachably connect two sheet-shaped airbags;
[0006] When the two sheet-like air bags are not inflated, the two sheet-like air bags and the connecting part fasten the nasal catheter to the user's nose;
[0007] When the two sheet-like air bags are inflated, the inner sides of the sheet-like air bags expand toward the cheeks of the user.
[0008] Furthermore, the outer sides of the two sheet-like airbags are made of non-deformable fabric, and when the two sheet-like airbags are inflated, the outer sides of the sheet-like airbags do not expand outwards.
[0009] Furthermore, the connecting portion is a detachable fastening belt from one end of the sheet-like airbag away from the nasal catheter, the other ends of the fastening belt are connected to each other via a buckle, and the length of the fastening belt can be adjusted by the buckle.
[0010] The high-flow machine nasal catheter oxygen inhalation fixing device also includes an arc-shaped strip air bag with both ends fixedly connected to the sheet air bag, the arc-shaped strip air bag spans the user's nose bridge, and the arc-shaped strip air bag is connected to the inside of the sheet air bag.
[0011] Furthermore, a manual air pump for inflating the sheet-like airbag and the arc-shaped strip airbag and an air release valve for deflating the sheet-like airbag and the arc-shaped strip airbag are provided on the sheet-like airbag, and the manual air pump and the air release valve are connected to the sheet-like airbag through an extension tube.
[0012] Furthermore, a third fastening portion is provided at the lower side of the nasal catheter, and the third fastening portion includes a fixing plate provided at the lower side of the nasal catheter, and the fixing plate fits the skin under the nose of the user.

[0025] The following examples further illustrate the content of the utility model, but should not be construed as limiting the utility model. Without departing from the spirit and essence of the utility model, modifications or replacements made to the methods, steps or conditions of the utility model are within the scope of the utility model.
[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0027] like Figure 1 As shown, the nasal cannula 1 is connected to the oxygen machine through the oxygen tube 2, an air inlet channel 101 is provided on one side of the nasal cannula, and the oxygen tube is connected to the air inlet channel through a thread, and two nasal suction tubes 102 are provided on the upper side of the nasal cannula 1. The nasal cannula is also provided with a fixing device, including two sheet air bags 301, and the sheet air bags 301 are symmetrically connected to the two sides of the nasal cannula 1, and each sheet air bag 301 is connected to the connecting part at one side away from the nasal cannula;
[0028] A connecting portion, the connecting portion being used to detachably connect two sheet-shaped airbags;
[0029] When the two sheet-like airbags 301 are not inflated, the two sheet-like airbags 301 and the connecting portion fasten the nasal catheter to the user's nose;
[0030] When the two sheet-like air bags are inflated, the inner sides of the sheet-like air bags expand toward the cheeks of the user.
[0031] The high-flow machine nasal cannula oxygen inhalation fixing device provided by the present application is a dual-purpose design, which can selectively inflate the sheet-like airbag. When the fixing strength of the nasal cannula needs to be adjusted, the size of the sheet-like airbag can be changed by inflating or deflating. When the two sheet-like airbags are inflated, their inner sides will expand toward the cheeks of the user, thereby increasing the fit between the nasal cannula and the face. This design not only improves the stability of wearing, but also improves the comfort of wearing. In addition, the inflation volume of the sheet-like airbag can be adjusted according to the needs of the patient, making the fixing strength of the nasal cannula more personalized.
[0032] Preferably, in some embodiments, the outer sides of the two sheet-like airbags are made of non-deformable fabric, and when the two sheet-like airbags are inflated, the outer sides of the sheet-like airbags do not expand outwards.
[0033] Non-deformable fabrics have a high degree of structural stability and shape retention, and can maintain their original shape and size even when subjected to external pressure or stretching. These fabrics can be made of materials such as hard plastics. When used to make the outside of a sheet airbag, this fabric can effectively prevent the outside of the airbag from expanding during inflation and improve the stability of the entire structure.
[0034] In some specific embodiments, the connection portion is detachably connected to one end of the sheet-like airbag 301 away from the nasal catheter with a fastening belt 302, and the other end of the fastening belt is connected to each other through a buckle 303, and the length of the fastening belt can be adjusted by the buckle.
[0035] The inner side of the sheet-like airbag 301 is made of soft and elastic material, which can fit the patient's face tightly when inflated to provide stable support. The fastening belt 302 is connected to each other through buckles 303, and the length can be adjusted as needed, so as to ensure that the device can adapt to patients with different face shapes and provide personalized fixing effects. This design not only improves the patient's comfort, but also effectively avoids the displacement of the nasal cannula.
[0036] Based on the above embodiments, Figure 2 As shown, the high-flow nasal catheter oxygen inhalation fixing device also includes an arc-shaped strip airbag 401 with both ends fixedly connected to the sheet airbag. The arc-shaped strip airbag 401 spans the user's nose bridge, and the arc-shaped strip airbag 401 is connected to the inside of the sheet airbag 301.
[0037] The arc-shaped strip airbag 401 is a soft and elastic material that can fit the user's nose bridge tightly. Both ends are fixedly connected to the sheet airbag 301 to ensure the stability and connectivity between the airbags. This design allows the gas inside the airbag to flow freely, forming a continuous air pressure system.
[0038] The arc-shaped strip airbag 401 can span the user's nose bridge, which can not only share the pressure of the sheet airbag 301, but also increase the contact area between the nose bridge and the equipment, thereby improving the wearing comfort. At the same time, the arc-shaped design can also adapt to different shapes of nose bridges, whether it is a high nose bridge or a low nose bridge, it can achieve a good fitting effect.
[0039] In addition, the design of the arc-shaped strip airbag 401 being connected to the sheet airbag 301 internally enables the entire protective equipment to form a complete air pressure system when inflated. When the sheet airbag 301 is inflated, the gas will flow into the arc-shaped strip airbag 401 through the connecting part, so that it is inflated synchronously.
[0040] In some embodiments, Figure 3 As shown, a manual air pump 304 for inflating the sheet-like airbag 301 and the arc-shaped strip airbag 401 and an air release valve 305 for deflating the sheet-like airbag 301 and the arc-shaped strip airbag 302 are provided on the sheet-like airbag 301, and the manual air pump 304 and the air release valve 305 are both connected to the sheet-like airbag 301 through an extension tube.
[0041] The manual air pump 304 and the deflation valve 305 are not directly connected to the sheet-shaped airbag 301, but are connected through an extension tube. This design not only increases the flexibility of operation, but also enables the user to inflate or deflate the airbag more conveniently. The use of the extension tube ensures the convenience of operation.
[0042] In some embodiments, Figure 4 As shown, a fixing sheet 501 is also provided on the lower side of the nasal catheter, and the fixing sheet fits the skin under the nose of the user.
[0043] The design of the fixing piece 501 takes ergonomics and comfort into consideration. It is made of soft, breathable material, so that it will not cause discomfort when it fits the user's skin, and can effectively fix the nasal cannula to prevent it from shifting or falling off due to activities or accidents. At the same time, the shape and size of the fixing piece 501 are also carefully designed to adapt to the facial structures of different users to the greatest extent, ensuring the versatility and comfort of the device.
[0044] Preferably, in some embodiments, the side of the sheet-like airbag 301 and the arc-shaped strip-like airbag 401 close to the skin is provided with a surface layer made of skin-friendly material.
[0045] Preferably, in some embodiments, the oxygen tube 2 is threadedly connected to the nasal catheter 1 .
[0046] The following is a detailed description of a specific usage process. Figure 5As shown, when in use, one end of the oxygen tube 2 is tightly connected to the oxygen machine, and the other end is installed to the air inlet interface 101 on the nasal catheter 1, and then the nasal suction tube 102 is placed in the user's nasal cavity, the fixing sheet 501 is close to the skin under the nose, the arc-shaped strip air bag 401 is placed across the user's nose bridge, the sheet air bag 301 is closely fitted to the patient's face, and the fastening belt 302 fixedly connected to the sheet air bag is worn around the user's head and locked by the buckle 303. The length can be adjusted as needed to ensure that the device can adapt to different patients. After wearing, the air bag can be inflated by the manual air pump 304 to make the nasal catheter firmly fit on the user's face, and the wearing tightness can be fine-tuned by the manual air pump 304 and the air release valve 305 to ensure the wearing comfort of the user.
[0047] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model based on the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
