The connecting line of the two fixing bracket plug interfaces 10 is parallel to the connecting line of the two adjusting buckle fixing structures 11, and the connecting line of the two fixing bracket plug interfaces 10 is located above the connecting line of the two adjusting buckle fixing structures 11.

[0043] A pair of fixing brackets 2, one end of which is provided with a fixing bracket plug 20, and the other end of which is provided with a fixing bracket fixing ring 21;

[0044] Headband 3, the headband 3 comprising:

[0045] X-shaped headband body 30, each of the two lower ends of the X-shaped headband body 30 is provided with a lower end adhesive fixing mechanism 31, and each lower end adhesive fixing mechanism 31 is equipped with an adjusting buckle 32;

[0046] A head adjustment strap 33 is provided, with a length adjustment mechanism 34 in the middle section. Both ends of the head adjustment strap 33 are provided with upper end adhesive fixing mechanisms 35, with each upper end adhesive fixing mechanism 35 corresponding to one fixing ring 21 of the fixing frame.

[0047] The two upper ends of the X-shaped headband body 30 are connected to the middle section of the head adjustment band 33, and the connection points of the two upper ends of the X-shaped headband body 30 and the middle section of the head adjustment band 33 are located between the upper end adhesive fixing mechanism 35 and the length adjustment mechanism 34 on the same side.

[0048] The mounting bracket 20 of one of the mounting brackets 2 corresponds to a mounting bracket plug interface 10, and the mounting bracket plug 20 is configured to be detachably plugged into the corresponding mounting bracket plug interface 10.

[0049] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0050] See Figures 1-3 As shown in the illustration, this application provides a medical nasal mask with ventilation, which includes:

[0051] The mouth and nose mask body 1 has a pair of fixing bracket plug interfaces 10 and a pair of adjusting buckle fixing structures 11 symmetrically arranged on the outer surface of the mouth and nose mask body 1. The connecting line of the two fixing bracket plug interfaces 10 is parallel to the connecting line of the two adjusting buckle fixing structures 11, and the connecting line of the two fixing bracket plug interfaces 10 is located above the connecting line of the two adjusting buckle fixing structures 11.

[0052] A pair of fixing brackets 2, one end of which is provided with a fixing bracket plug 20, and the other end of which is provided with a fixing bracket fixing ring 21;

[0053] Headband 3, the headband 3 comprising:

[0054] X-shaped headband body 30, each of the two lower ends of the X-shaped headband body 30 is provided with a lower end adhesive fixing mechanism 31, and each lower end adhesive fixing mechanism 31 is equipped with an adjusting buckle 32;

[0055] A head adjustment strap 33 is provided, with a length adjustment mechanism 34 in the middle section. Both ends of the head adjustment strap 33 are provided with upper end adhesive fixing mechanisms 35, with each upper end adhesive fixing mechanism 35 corresponding to one fixing ring 21 of the fixing frame.

[0056] The two upper ends of the X-shaped headband body 30 are connected to the middle section of the head adjustment band 33, and the connection points of the two upper ends of the X-shaped headband body 30 and the middle section of the head adjustment band 33 are located between the upper end adhesive fixing mechanism 35 and the length adjustment mechanism 34 on the same side.

[0057] The mounting bracket 20 of one of the mounting brackets 2 corresponds to a mounting bracket plug interface 10, and the mounting bracket plug 20 is configured to be detachably plugged into the corresponding mounting bracket plug interface 10.

[0058] It should be noted that traditional mouth and nose masks, in order to connect and fix the facial frame with other components, use a design that connects and fixes the head components in series. Prolonged wear can cause dizziness and a feeling of oppression in patients. The manufacturing process is complex and the production cost is high.

[0059] In comparison, this application has the following two innovative advantages:

[0060] The main frame components are integrally injection molded, effectively adhering to the original design concept, resulting in a simpler and more aesthetically pleasing appearance. While meeting performance strength requirements, the weight has been significantly reduced from a market-standard level, making it more convenient and lightweight for patients to use. The structural design is simple, the manufacturing process is smooth, and the manufacturing cost is lower.

[0061] 2. Innovative structural design of the fixed support component. The curved extension connection of the main frame component is achieved by inserting one side into the matching point and then pushing the other side forward to the matching point through vertical force. When the component is pushed inwards by the force, the point that was squeezed will spring back and lock in place. Its shape is arc-shaped. The design is simple and assembly is quick.

[0062] In this embodiment, a fixing structure for the mouth and nose mask is formed by a fixing frame and an X-shaped headband structure. While ensuring sufficient strength, it avoids obstructing vision and has the advantages of convenient assembly and low cost.

[0063] Furthermore, the adjusting buckle fixing structure 11 includes a set of spaced first fixing plates 110 disposed on the mouth and nose mask body 1 and a first fixing rod 111 disposed between the two first fixing plates 110;

[0064] The adjusting buckle 32 includes:

[0065] Adjustment buckle body 320 that matches the first fixing rod 111;

[0066] Adjustment buckle fixing ring 321 is provided at the end of the adjustment buckle body 320;

[0067] One of the lower end adhesive fixing mechanisms 31 corresponds to one of the adjusting buckle fixing rings 321.

[0068] Furthermore, the lower end adhesive fixing mechanism 31 consists of a Velcro front surface and a Velcro back surface spaced apart on the lower end of the X-shaped headband body 30;

[0069] The lower end adhesive fixing mechanism 31 is configured to form a fixing structure for fixing the adjusting buckle fixing ring 321 when the lower end of the X-shaped headband body 30 is bent and the Velcro female side and the Velcro female side of the lower end adhesive fixing mechanism 31 are mated.

[0070] The upper adhesive fixing mechanism 35 consists of a Velcro front side and a Velcro back side spaced apart on the head adjustment strap 33.

[0071] The upper adhesive fixing mechanism 35 is configured to form a fixing structure for fixing the fixing ring 21 of the fixing frame when the two ends of the head adjustment strap 33 are bent and the Velcro female side and the Velcro female side of the upper adhesive fixing mechanism 35 are engaged.

[0072] Furthermore, the fixing frame 2 has an arc-shaped structure, with an elastic structure in its middle section.

[0073] Furthermore, a support sleeve 22 is fitted over the middle section of the fixing frame 2.

[0074] Furthermore, the horizontal height of the fixing bracket plug 20 is lower than the horizontal height of the fixing bracket fixing ring 21.

[0075] Specifically, in the technical solution of this application embodiment, the structure design of the fixing frame 2 is innovative. When the curved extension connection of the body 1 of the mouth and nose mask is inserted into the matching point on one side and pushed to the matching point by vertical force on the other side, the point of the fixing frame plug 20 of the fixing frame 2 that is squeezed in will spring back and be locked. Its shape is arc-shaped, which is simple in design and quick to assemble.

[0076] In practical operation, the fixing structure of the technical solution of this application embodiment is simple, consisting of left and right fixing frames, with an overall weight of about 88g. It is light and comfortable for patients to wear, and the weight is 1 / 4 lighter than similar products, reducing packaging and transportation costs. The headband avoids wrapping around the forehead and does not interfere with the patient's vision, avoiding adverse events such as "esotropia" that may occur with long-term wear in clinical practice, thus increasing the safety of patient use. The fixing is done by a pin, which facilitates assembly on the production line, ensures consistent production quality, and improves product quality.

[0077] Both the left and right fixed brackets are universal fitting frame main components with curved surface extension connections. When one side is inserted into the matching point, the other side is pushed into the matching point by vertical force. When the component is squeezed and dented, the point that is indented will spring back and lock in place. Its shape is arc-shaped, with a simple design and quick assembly.

[0078] The processing technology of the technical solution in this application embodiment is as follows: the fixed bracket is made of PP material by injection molding through a customized mold, and the process includes baking / curing / thermoplasticizing / demolding / trimming, etc.

[0079] The assembly principle of the technical solution in this application embodiment is as follows: the two head straps are connected by the two fixing frames 2 on the left and right sides, which is simple, easy to assemble, easy to load, and easy to disassemble.

[0080] It should be noted that in the technical solution of this application embodiment, the main frame component is integrally injection molded, which effectively fits the original design concept, and the appearance is simpler and more beautiful. From the perspective of the product weight based on the market, while meeting the strength requirements of performance, the weight is greatly reduced, making it more convenient and lighter for patients to use. The structural design is simple, the manufacturing process is smooth, and the manufacturing cost is lower.
