[0002] Oxygen masks are an important rescue channel for providing oxygen to critically ill patients. Mask oxygen inhalation is mainly used for critically ill patients with breathing difficulties. The oxygen supply is relatively large. Generally, different flow rates are selected according to the condition, age, body position, etc. It is very important to ensure effective and safe oxygen therapy concentration during use.

[0003] The patent with announcement number CN217286810U discloses an oxygen mask suitable for patients with gastric tube insertion, including a mask body with exhaust holes on both sides of the mask body; also including one or two gastric tube fixing structures; when there is one gastric tube fixing structure, the gastric tube fixing structure is arranged corresponding to any exhaust hole; when there are two gastric tube fixing structures, the gastric tube fixing structures and the exhaust holes are arranged one by one; the gastric tube fixing structure includes a fixing seat, an elastic sleeve and a pressure cover, the fixing seat has a conical hole, the elastic sleeve is conical in shape, the center of the elastic sleeve has a gastric tube pressing hole, the elastic sleeve has a deformation seam, the elastic sleeve is inserted into the conical hole, the pressure cover has a gastric tube passing hole, the pressure cover is sleeved on the fixing seat and is threadedly connected to the fixing seat, and the pressure cover can press the elastic sleeve internally to shrink the elastic sleeve.

[0004] Oxygen masks such as the above need to be pressed tightly against the face in order to fit the oxygen mask tightly against the face, which results in a great pressure on the face from the oxygen mask. In addition, the mask is made of non-breathable plastic material, and the straps are also made of elastic material. When used by patients, the mask and straps will be pressed against the skin and redness and indentations will occur. Long-term use can cause pressure sores on the nose and face, and the patient's comfort is poor. At the same time, when the gastric tube is inserted into the oxygen mask and worn, it is inserted vertically, which takes up more space and has a certain impact on the stability of the mask. The gastric tube is also easily pulled during the patient's activities, causing the gastric tube to be easily bent and deformed, and the patency of the gastric tube cannot be guaranteed.

[0032] like Figure 1-4As shown, the utility model provides an improved anti-pressure oxygen mask, comprising a mask body 1, and an oxygen tube interface 3 arranged at the lower side of the mask body 1 for connecting an oxygen tube, through which oxygen can be connected for the patient to breathe, the oxygen tube interface 3 is arranged at the lower side of the mask body 1, and is located below the patient's nostrils during wearing, and an exhaust hole 11 is arranged at the upper side of the oxygen tube interface 3 to facilitate the discharge of gas generated by the patient's breathing, a buffering protective airbag 2 is arranged at the edge of the mask body 1 to prevent pressure marks on the patient, and after the buffering protective airbag 2 is filled with gas, it will play a certain buffering role when the mask body 1 is worn, avoiding pressure marks on the patient The mask body 1 is provided with a plurality of fixing belts 5 for fixing the mask body 1, and the fixing belts 5 are detachably connected at the free ends. The fixing belts 5 are made of non-elastic material, which can avoid the elastic material from causing marks due to the elastic effect during use, which will cause discomfort to the patient; gastric tube notches 13 are symmetrically arranged on both sides of the lower end of the mask body 1 about the oxygen inhalation tube interface 3, and the two gastric tube notches 13 are covered by a sealing baffle 4. The gastric tube notches 13 can avoid deformation of the gastric tube due to extrusion during use and affect normal use.

[0033] In the above scheme, the cushioning protection airbag 2 is detachably connected to the edge of the mask body 1 , and an inflation and exhaust port 21 is provided on the cushioning protection airbag 2 , and a sealing plug 22 is connected to the inflation and exhaust port 21 .

[0034] As an optimized technical solution of the utility model, an appropriate amount of gas can be filled into the buffer protection airbag 2 through the inflation and exhaust port 21, so that the buffer protection airbag 2 has a buffering and protective effect. While ensuring that no pressure sores are caused on the patient's face, the sealing of the oxygen mask can also be ensured, which can greatly improve the patient's comfort during use.

[0035] In the above scheme, the sealing baffle 4 is an elastic structure, the sealing baffle 4 is located on the inner side of the mask body 1, and the sealing baffle 4 is rotatably connected to the edge of the gastric tube notch 13.

[0036] As an optimized technical solution of the utility model, the sealing baffle 4 is an elastic structure, which can always keep in contact with the inner wall of the mask body 1. Two gastric tube notches 13 are provided on the mask body 1, which can prevent the gastric tube from being squeezed by the mask body 1 and causing deformation, and also can prevent the gastric tube from pressing on the patient's skin and causing discomfort to the patient. The gastric tube notch 13 is covered by the sealing baffle 4 to have a sealing effect, preventing the leakage of oxygen in the mask body 1. When the gastric tube needs to be inserted, the sealing baffle 4 only needs to be rotated to the outside of the gastric tube notch 13, so that the gastric tube notch 13 is opened to facilitate the insertion of the gastric tube.

[0037] In the above scheme, a fixing ring 12 is respectively provided on the left and right sides of the mask body 1, and the fixing belt 5 is detachably connected to the fixing ring 5; the fixing belt 5 includes a connecting belt 51, a first adhesive portion 52 and a second adhesive portion 53, and the first adhesive portion 52 and the second adhesive portion 53 are respectively connected to the two ends of the connecting belt 51; the first adhesive portion 52 is connected to the fixing ring 12, and the free ends of the second adhesive portion 53 are adhered to each other.

[0038] As an optimized technical solution of the present invention, the fixing strap 5 is detachably connected to the mask body 1 through the fixing ring 12, which is conducive to its disassembly, cleaning and disinfection, and is also convenient for its storage and arrangement to avoid the entanglement and knotting of the straps. At the same time, the fixing strap 5 is made of non-elastic material, which can avoid the elastic effect of the elastic material causing marks on the patient, thereby causing discomfort to the patient. The tightness of the fixing strap 5 is adjusted by the length of the adhesion after the overlap of the second adhesive part 53, ensuring that the mask body 1 can be stably worn on the patient's face.

[0039] In the above solution, the first adhesive portion 52 is composed of a first Velcro 521 and a second Velcro 522 , and the second Velcro 522 passes through the fixing ring 12 and is adhered to the first Velcro 521 .

[0040] As an optimized technical solution of the utility model, the second Velcro 522 passes through the fixing ring 12 and then adheres to the first Velcro 521, so that the fixing belt 5 can be fixed on the mask body 1, and then the oxygen mask and the patient's head can be fixed by the mutual adhesion of the free ends of the second adhesive portion 53. Example

[0041] like Figure 5 As shown, based on Example 1, the difference from Example 1 is that a nose bridge buffer pad 6 for protecting the patient's nose bridge from mechanical damage is provided on the inner side of the mask body 1, and a protective groove 61 adaptive to the patient's nose bridge is provided in the middle of the nose bridge buffer pad 6.

[0042] As an optimization technical solution of the utility model, the nose bridge buffer pad 6 can play a buffering and protective role on the patient's nose bridge when the mask body 1 covers the patient's face, preventing pressure sores on the patient's nose bridge caused by long-term use of the oxygen mask. At the same time, the protective groove 61 can correspond to the patient's nose bridge and play a certain limiting role, preventing the mask body 1 from easily deviating and thus affecting the oxygen absorption effect.

[0043] Specific implementation cases:

[0044] Oxygen masks are currently the most commonly used medical devices for oxygen inhalation in clinical practice. The mask oxygen inhalation therapy can ensure the patient's oxygenation, improve the blood oxygen ratio, and promote metabolism. It is one of the methods for auxiliary treatment of various diseases and has a relatively important significance in clinical work, especially for patients after anesthesia surgery. Oxygen masks provide important clinical support for the smooth transition of such patients during the perioperative period.

[0045] Therefore, when the patient needs oxygen inhalation, the fixing belt 5 is connected to the mask body 1 through the second Velcro 522 through the fixing ring 12 and the first Velcro 521, and then the mask body 1 is buckled on the patient's face, and the nose bridge buffer pad 6 is placed against the patient's nose bridge, and the nose bridge is stuck in the protective groove 61. The free ends of the second adhesive parts 53 on both sides of the mask body 1 are then wrapped around the patient's head and adhered and fixed, thereby fixing the mask body 1 on the patient's face.

[0046] At that time, the sealing plug 22 is opened, and gas is filled into the buffer protection airbag 2 from the inflation and exhaust port 21, so that the buffer protection airbag 2 slowly expands, which has a buffering effect on the patient's face and also makes the fixing belt 5 tightened. At the same time, due to the filling of gas, the buffer protection airbag 2 adapts itself to fit the patient's face according to the patient's facial curve, which has a good sealing effect and prevents the leakage of oxygen in the mask body 1.

[0047] Next, oxygen is connected to the oxygen tube interface 3 for oxygen therapy. If a gastric tube is to be inserted, the sealing baffle 4 can be opened and the gastric tube can be inserted from the gastric tube notch 13. This can prevent the gastric tube from being deformed and affecting normal use, and can also prevent the gastric tube from pressing on the patient's skin. It also has a certain restraining effect on the gastric tube, so that the gastric tube will not be arranged in a disordered manner.

[0048] Finally, when the oxygen inhalation therapy is finished, the fixing belt 5 can be removed from the mask body 1 and cleaned and disinfected for the next use.

[0049] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
