Technical Field

[0001] The utility model relates to the technical field of oxygen masks, in particular to a universal fitting oxygen mask which can prevent air leakage at the edges. Background Art

[0002] An oxygen mask is a medical device used to provide additional oxygen to patients who have difficulty breathing or are suffering from hypoxia. The mask is connected to an oxygen source through a tube, which delivers pure oxygen to the patient's mouth and nose, increasing the oxygen content in the blood, thereby improving the patient's breathing and physical condition. Oxygen masks are suitable for a variety of respiratory diseases, such as asthma, pneumonia, chronic obstructive pulmonary disease, etc. They are widely used in hospitals, ambulances, and home care.

[0003] In the prior art, oxygen masks for adults are universal, so the oxygen masks produced are of uniform size standards. This results in that when some patients use the oxygen masks, due to differences in personal face shapes, the oxygen masks cannot fit the patients' faces, and a gap appears between the oxygen masks and the patients' faces, thereby affecting the oxygen delivery effect. Utility Model Content

[0004] The utility model aims to solve the problem that in the prior art, oxygen masks for adults are universal, so the sizes of the manufactured oxygen masks are standardized, which leads to that when some patients use the oxygen masks, the oxygen masks cannot fit the faces of the patients due to differences in personal face shapes, and a gap appears between the oxygen masks and the faces of the patients, thereby affecting the oxygen delivery effect. A universal fitting oxygen mask that prevents edge leakage is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a universal fitting oxygen mask for preventing edge leakage, comprising: a mask body, a plurality of fixing columns are evenly and fixedly connected to the rear surface of the mask body, a shrinking component is arranged on the rear surface of the mask body, and a connecting component is arranged on the inner surface of the mask body; a shrinking component, the shrinking component comprises a rubber pad, a front surface of the rubber pad is provided with an annular groove, the inner surface wall of the annular groove is slidably connected to the outer surface of the mask body, a plurality of hollow columns are evenly arranged on the rear bottom surface of the annular groove, the hollow columns are matched with the fixing columns, a plurality of springs are respectively arranged on the inner surfaces of the plurality of hollow columns, and the springs are matched with the fixing columns.

[0006] Preferably, the connection assembly comprises a connection pipe, the outer surface of the connection pipe is fixedly connected to the inner surface of the mask body, the inner surface of the connection pipe is matched with an oxygen tube body, the outer surface of the oxygen tube body is sleeved with a connection sleeve, and the outer surface of the connection sleeve is threadedly connected to the outer surface of the connection pipe.

[0007] Preferably, a limiting ring is fixedly connected to the outer surface of the oxygen tube body, and the limiting ring is matched with the connecting sleeve.

[0008] Preferably, a plurality of air inlet holes are evenly formed on the outer surface of the connecting pipe.

[0009] Preferably, a guide block is fixedly connected to the inner surface of the connecting pipe, and the guide block is matched with the air inlet hole.

[0010] Preferably, a plurality of fixing blocks are symmetrically arranged on the outer surface of the mask body, and elastic bands are symmetrically arranged between the rear surfaces of the plurality of fixing blocks.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when the patient wears the oxygen mask, the mask body and the rubber cushion are pulled toward the patient's face through the elastic contraction of the two elastics. At the same time, a plurality of hollow columns arranged on the rear surface of the mask body slide backward in the corresponding hollow columns to squeeze the corresponding springs. The plurality of springs squeeze the corresponding fixed columns respectively under the action of the reset elasticity. The reaction force generated by the plurality of springs drives the rubber cushion to fit closely to the patient's face, avoiding the generation of gaps at the edge of the oxygen mask, thereby improving the oxygen delivery effect of the oxygen mask.

[0013] 2. In the utility model, when in use, the oxygen tube body is held and inserted into the corresponding connecting tube, and under the limiting effect of the limiting ring, the oxygen tube body is prevented from being over-inserted, and at the same time, the connecting sleeve is held and rotated on the outer surface of the connecting tube, so that the connecting tube and the connecting sleeve are threadedly connected, and the connecting sleeve will tightly connect the oxygen tube body to the connecting tube through the limiting ring, which plays a role of connection and fixing. By arranging a guide block on the inner surface of the connecting tube, the oxygen is forced to flow into the oxygen mask from the air inlet holes evenly opened on the outer surface of the connecting tube, which plays a buffering role, avoids the discomfort caused by oxygen being poured into the patient's mouth, and improves the patient's comfort when using the oxygen mask.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a universal fitting oxygen mask for preventing edge leakage, comprising: a mask body 1, a plurality of fixing columns 6 are evenly fixedly connected to the rear surface of the mask body 1, a contraction component 2 is arranged on the rear surface of the mask body 1, and a connection component 3 is arranged on the inner surface of the mask body 1; the contraction component 2 comprises a rubber cushion 201, an annular groove 202 is provided on the front surface of the rubber cushion 201, the inner surface wall of the annular groove 202 is slidably connected to the outer surface of the mask body 1, a plurality of hollow columns 203 are evenly arranged on the rear bottom surface of the annular groove 202, the hollow columns 203 are matched with the fixing columns 6, and a plurality of springs 204 are respectively arranged on the inner surfaces of the plurality of hollow columns 203, and the springs 204 are matched with the fixing columns 6. A plurality of fixing blocks 4 are symmetrically arranged on the outer surface of the mask body 1, and elastic bands 5 are symmetrically arranged between the rear surfaces of the plurality of fixing blocks 4.

[0023] The effect achieved by the entire embodiment 1 is that when the universal fitting oxygen mask that prevents edge leakage is used, when the patient wears it through the two elastic bands 5, due to the elastic force of the elastic bands 5, the two elastic bands 5 respectively generate tension on the mask body 1 through the corresponding fixing blocks 4, which will drive the mask body 1 and the rubber cushion 201 to be pressed on the patient's face. At this time, the multiple fixing columns 6 arranged on the rear surface of the mask body 1 will slide into the corresponding hollow columns 203 respectively, and the multiple fixing columns 6 will respectively squeeze the springs 204 arranged in the corresponding fixing columns 6. After the springs 204 are deformed by the force, they will squeeze the fixing columns 6 respectively through their own elastic action. At this time, a reaction force will be generated on the rubber cushion 201, and the outer surface of the mask body 1 will shrink into the annular groove 202, so that the rear surface of the rubber cushion 201 will fit closely to the patient's face, avoiding a gap between the mask body 1 and the patient's face, thereby improving the delivery effect of the oxygen mask.

[0024] Embodiment 2, as Figure 1-Figure 5 As shown, the connection assembly 3 includes a connection pipe 301, the outer surface of the connection pipe 301 is fixedly connected to the inner surface of the mask body 1, the inner surface of the connection pipe 301 is matched with an oxygen tube body 305, the outer surface of the oxygen tube body 305 is sleeved with a connection sleeve 304, the outer surface of the connection sleeve 304 is threadedly connected to the outer surface of the connection pipe 301, and the outer surface of the oxygen tube body 305 is fixedly connected to a limit ring 306, and the limit ring 306 is matched with the connection sleeve 304. A plurality of air inlet holes 302 are evenly opened on the outer surface of the connection pipe 301. A guide block 303 is fixedly connected to the inner surface of the connection pipe 301, and the guide block 303 is matched with the air inlet hole 302.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, by holding the oxygen tube body 305 and inserting the air outlet end into the corresponding connecting pipe 301, the outer surface of the oxygen tube body 305 will slide with the inner surface of the connecting pipe 301, and stop sliding under the blocking effect of the limit ring 306, so as to avoid excessive insertion of the oxygen tube body 305, and then hold the outer surface of the connecting sleeve 304, so that the inner surface of the connecting sleeve 304 rotates on the outer surface of the connecting pipe 301, so that the connecting sleeve 304 and the connecting pipe 301 are threadedly fixedly connected. The limiting ring 306 is fixed between the connecting sleeve 304 and the connecting pipe 301, which plays a role in connecting and fixing the oxygen tube body 305. When oxygen flows in the oxygen tube body 305, it will enter the oxygen mask 1 through the connecting pipe 301. By arranging a guide block 303 on the inner surface of the connecting pipe 301, the flowing oxygen is forced to flow into the oxygen mask 1 from the air inlet holes 302 evenly opened on the outer surface of the connecting pipe 301, thereby preventing oxygen from directly entering the patient's mouth and nose and causing discomfort to the patient.

[0026] Working principle: When in use, when the patient wears the oxygen mask through the two elastic bands 5, the two elastic bands 5 will respectively generate pulling force on the mask body 1 through the corresponding fixing blocks 4. At this time, the mask body 1 slides in the corresponding hollow columns 203 through multiple fixing columns 6. The multiple fixing columns 6 will squeeze the corresponding springs 204 respectively. The springs 204 will deform after being squeezed. When squeezing the fixing columns 6 under the action of their own elasticity, a reaction force will be generated on the rubber pad 201. The spring 204 will drive the rubber pad 201 to fit closely to the patient's face, avoiding gaps on the patient's face, which will cause oxygen to leak out from the gaps, thereby improving the delivery effect of the oxygen mask.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
