Description

Technical Field

[0001] The utility model relates to the technical field of oxygen masks, in particular to an oxygen mask which is reliably fixed. Background Art

[0002] An oxygen mask is an emergency life-saving device that provides oxygen. Its main function is to transfer oxygen from a storage tank to the human lungs. In medicine, it is mainly used for critically ill patients, such as those with bronchitis, asthma, high altitude hypoxia, respiratory failure, and other situations that require oxygen therapy. At the same time, in the field of civil aviation, oxygen masks are emergency life-saving devices that provide oxygen to passengers. For example, if the air in the cabin is thin or the oxygen content is insufficient, the oxygen mask will automatically fall off, and passengers can maintain normal breathing function by breathing oxygen to avoid the danger caused by hypoxia. In addition, oxygen masks are also widely used in military, diving and other fields, and are one of the important equipment to ensure the safety of personnel lives.

[0003] In some emergency situations, the existing oxygen masks have too many traction ropes, which are inconvenient to fix and cannot be quickly and easily deployed on the patient's mouth and nose. Moreover, when the oxygen mask is quickly put on, it is impossible to ensure good sealing and comfort between the oxygen mask and the face. Utility Model Content

[0004] Aiming at the defects in the prior art, the utility model provides an oxygen mask which can be fixed reliably.

[0005] A reliably fixed oxygen mask comprises a mask body, the center of the mask body is convex and formed with an oral and nasal cavity, the oral and nasal cavity is connected to a breathing joint fixed on the mask body; wherein, the mask body is integrally formed with a deformable extension side body around it, the extension side body gradually bends and extends outward and forms an annular mounting groove between it and the front side wall of the mask body, the annular mounting groove surrounds the entire mask body; a left fixing seat and a right fixing seat are respectively arranged on the left and right sides of the mask body, the left fixing seat and the right fixing seat are both located inside the annular mounting groove, and a traction rope is arranged between the left fixing seat and the right fixing seat; an elastic structure is fitted inside the annular mounting groove, and two ends of the traction rope pass through the left fixing seat and the right fixing seat respectively and are connected to two ends of the elastic structure.

[0006] Preferably, a left traction channel is provided in the left fixing seat, and the left end of the traction rope is passed through the left traction channel. After the traction rope passes through the left traction channel, its position is relatively fixed and is not easy to slide or shift, which ensures the stability of the oxygen mask when worn; further, the user can quickly fine-tune the sealing of the left part of the mask body by simply pulling the traction rope.

[0007] Preferably, a right traction channel is provided in the right fixing seat, and the right end of the traction rope is passed through the right traction channel. Similarly, after the traction rope passes through the right traction channel, its position is relatively fixed and is not easy to slide or shift, which ensures the stability of the oxygen mask when worn; further, the user can quickly fine-tune the sealing of the right side of the mask body by simply pulling the traction rope.

[0008] Preferably, the middle section of the elastic structure is located at the top of the mask body. The middle section of the elastic structure is located at the top of the mask body, which helps to increase the pressure of the mask body on the bridge of the nose, so that the elastic structure above can adapt to the curve around the bridge of the nose, so that the entire mask body fits the facial contour better, rather than applying too much pressure on a specific area.

[0009] Preferably, the middle section of the elastic structure is located at the bottom of the mask body. Placing the middle section of the elastic structure at the bottom of the mask helps to better adapt to the patient's jaw line. Since the shape and size of the jaw vary from person to person, this design can ensure that the mask fits better when worn and reduce the risk of oxygen leakage.

[0010] Preferably, an anti-suffocation valve is provided on the mask body. The main function of the anti-suffocation valve is to automatically open when the oxygen supply is interrupted or insufficient, allowing external air to enter the mask, thereby preventing the user from suffocating due to lack of oxygen. This is crucial for patients who rely on oxygen masks for breathing, especially in low-oxygen environments such as flying, diving or high altitudes.

[0011] Preferably, two anti-suffocation valves are provided and are respectively located on the left and right sides of the mask body. By providing two anti-suffocation valves, even if one of the valves fails to work properly due to a malfunction or blockage, the other valve can still function to ensure that external air can enter the mask, thereby providing double safety protection for the user.

[0012] The beneficial effects of the utility model are embodied in:

[0013] In the entire fixed and reliable oxygen mask of the utility model, by simplifying the design of the traction rope body and adopting the traction rope between the left fixing seat and the right fixing seat, the mask body can be quickly and accurately positioned on the patient's face to achieve rapid deployment; further, the deformable extension side body integrally formed around the mask body and the annular mounting groove formed between the front side wall of the mask body, these designs help the oxygen mask to better adapt to the facial contours of different patients, thereby improving the sealing between the oxygen mask and the face, and the improvement of the sealing can ensure that oxygen is more effectively delivered to the patient's lungs and avoid oxygen waste; further, the two ends of the traction rope pass through the left fixing seat and the right fixing seat respectively, and are connected to the two ends of the elastic structure. The traction rope will pull the elastic structure during wearing, and the elastic structure will automatically squeeze the extension side body. The extension side body will automatically deform adaptively according to the facial shape of the patient under squeezing, which helps to improve the sealing between the oxygen mask and the face, and can also reduce discomfort when wearing. At the same time, even when the patient moves or the external environment changes, the elastic structure compresses the extension side body to keep the mask body fixed in the correct position.

[0023] like Figures 1 to 3 As shown, a reliably fixed oxygen mask comprises a mask body 1, the center of the mask body 1 is convex and formed with an oral and nasal cavity 2, and the oral and nasal cavity 2 is connected to a breathing joint 3 fixed on the mask body 1; wherein, the mask body 1 is integrally formed with a deformable extension side body 4 around it, the extension side body 4 gradually bends and extends outward and forms an annular mounting groove 41 between the front side wall of the mask body 1, and the annular mounting groove 41 surrounds the entire mask body 1; a left fixing seat 5 and a right fixing seat 6 are respectively arranged on the left and right sides of the mask body 1, the left fixing seat 5 and the right fixing seat 6 are both located inside the annular mounting groove 41, and a traction rope is arranged between the left fixing seat 5 and the right fixing seat 6; an elastic structure 7 is fitted inside the annular mounting groove 41, and two ends of the traction rope pass through the left fixing seat 5 and the right fixing seat 6 respectively and are connected to two ends of the elastic structure 7.

[0024] In the present embodiment, it should be noted that, in the entire fixed and reliable oxygen mask, by simplifying the design of the traction rope body, a traction rope is used between the left fixing seat 5 and the right fixing seat 6, so that the mask body 1 can be quickly and accurately positioned on the patient's face, and rapid deployment is achieved; further, the deformable extension side body 4 integrally formed around the mask body 1, and the annular mounting groove 41 formed between the front side wall of the mask body 1, these designs help the oxygen mask to better adapt to the facial contours of different patients, thereby improving the sealing between the oxygen mask and the face, and the improvement of the sealing can ensure that oxygen is more effectively delivered to the patient's lungs, avoiding oxygen waste; further, the two ends of the traction rope pass through the left fixing seat 5 and the right fixing seat 6 respectively, and are connected to the two ends of the elastic structure 7. The traction rope will pull the elastic structure 7 during wearing, and the elastic structure 7 will automatically squeeze the extension side body 4. The extension side body 4 automatically deforms adaptively according to the facial shape of the patient under squeezing, which helps to improve the sealing between the oxygen mask and the face, and can also reduce the discomfort when wearing. At the same time, even when the patient moves or the external environment changes, the elastic structure 7 compresses the extension side body 4 to keep the mask body 1 fixed in the correct position.

[0025] Specifically, a left traction channel 51 is provided in the left fixing seat 5 , and the left end of the traction rope is passed through the left traction channel 51 .

[0026] In this embodiment, it should be noted that after the traction rope passes through the left traction channel 51, its position is relatively fixed and is not easy to slide or shift, which ensures the stability of the oxygen mask when worn; further, the user can quickly fine-tune the sealing of the left part of the mask body 1 by simply pulling the traction rope.

[0027] Specifically, a right traction channel 61 is provided in the right fixing seat 6 , and the right end of the traction rope is passed through the right traction channel 51 .

[0028] In the present embodiment, it should be noted that, similarly, after the traction rope passes through the right traction channel 61, its position is relatively fixed and is not easy to slide or shift, which ensures the stability of the oxygen mask when worn; further, the user can quickly fine-tune the sealing of the right side of the mask body 1 by simply pulling the traction rope.

[0029] Specifically, the middle section of the elastic structure 7 is located at the top of the mask body 1 .

[0030] In this embodiment, it should be noted that the middle section of the elastic structure 7 is located at the top of the mask body 1, which helps to increase the pressure of the mask body 1 on the bridge of the nose, so that the upper elastic structure 7 can adapt to the curve around the bridge of the nose, making the entire mask body 1 more fit the facial contour, rather than applying too much pressure on a specific area.

[0031] Specifically, the middle section of the elastic structure 7 is located at the bottom of the mask body 1 .

[0032] In this embodiment, it should be noted that placing the middle section of the elastic structure 7 at the bottom of the mask helps to better adapt to the patient's jaw line. Since the shape and size of the jaw vary from person to person, this design can ensure that the mask fits better when worn and reduce the risk of oxygen leakage.

[0033] Specifically, an anti-suffocation valve 8 is provided on the mask body 1 .

[0034] In this embodiment, it should be noted that the main function of the anti-suffocation valve 8 is to automatically open when the oxygen supply is interrupted or insufficient, allowing external air to enter the mask, thereby preventing the user from suffocating due to lack of oxygen. This is very important for patients who rely on oxygen masks for breathing, especially in low-oxygen environments such as flying, diving or high altitudes.

[0035] Specifically, two anti-suffocation valves 8 are provided and are respectively located on the left and right sides of the mask body 1 .

[0036] In this embodiment, it should be noted that by providing two anti-suffocation valves 8, even if one of the valves fails to work normally due to a malfunction or blockage, the other valve can still function to ensure that external air can enter the mask, thereby providing double safety protection for the user.
