[0022] To better understand this utility model, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] A headband for an oxygen mask / gas mask includes a back-of-head fastener 1 and an elastic fastening strap 3. The back-of-head fastener 1 includes a first headband and a second headband, with the two ends of the first and second headbands connected as a single unit. A fastening strap hole 14 is provided on the common part 13 where the two headbands are connected. The back-of-head fastener 1 is made of silicone, rubber, or plastic for easy processing. Some oxygen masks or gas masks have a strap fastening hole at the connection point between the connecting tube and the mask body for installing the fastening strap. The two ends of the elastic fastening strap 3 pass through the fastening strap hole and extend outward, respectively, and are fixed to the strap fastening hole on the same side. The free end of the elastic fastening strap 3 can have a hook-and-loop fastener on one side and a hook side on the other side. The free end of the elastic fastening strap passes through the strap fastening hole of the mask and is then glued together to complete the fixation. The portion of the elastic fastening strap 3 between the back-of-head fastener 1 forms a forehead strap 31, and the portion of the elastic fastening strap 3 between the back-of-head fastener 1 and the mask fastener 2 forms a face strap 32.

[0025] After wearing, the first and second headbands of the head-retaining component 1 form a stable triangular structure with the forehead strap 31, and the head-retaining component 1 also forms a stable triangular structure with the two face straps 32. This securely fixes the mask to the patient's face. The oxygen mask / gas mask fixing headband described in this embodiment is easy to wear and provides a more secure and stable fixation; the overall structure is simple, the manufacturing cost is low, and it is suitable for widespread application.

[0026] Example 2

[0027] like Figure 1 As shown, a head strap for an oxygen mask / gas mask includes a rear head fastener 1, a mask fastener 2, and an elastic fastening strap 3. The rear head fastener 1 includes a first head strap and a second head strap, the two ends of which are connected as one piece, and a fastening strap hole 14 is provided on the common part 13 of the connected part. The rear head fastener 1 is made of silicone, rubber, or plastic, which is easy to process.

[0028] The mask fastener 2 is used to install the mask and press it against the patient's mouth and nose. The mask fastener 2 includes a mask retainer 21 and extensions 22 at both ends of the retainer 21. The extensions 22 are equipped with strap buckles 221. The mask typically includes a mask body and a connecting tube connected to the mask body. The mask retainer 21 is fitted onto the connecting tube, connecting the mask to the mask fastener 2. The inner wall of the mask retainer 21 also has multiple protrusions 211, which allow the retainer 21 to press the mask firmly, ensuring a secure installation.

[0029] The elastic band 3 passes through both ends of the head-back fastener 1 and is then installed in the strap buckle 221. The portion of the elastic band 3 between the head-back fastener 1 forms the forehead band 31, and the portion of the elastic band 3 between the head-back fastener 1 and the mask fastener 2 forms the face band 32. The strap buckle 221 can be a U-shaped backpack buckle to adjust the length of the elastic band 3, thus tightening or loosening it. Alternatively, the strap buckle 221 can be replaced with a through hole, and Velcro fasteners 4 are provided at both ends of the elastic band 3, with each end of the elastic band 3 fixed in a through hole on the same side of the mask fastener.

[0030] When wearing the mask, first insert the mask connecting tube into the mask retainer 21, ensuring the main body of the mask faces the head-mounted fastener 1. Then, slip the head-mounted fastener 1 over the back of the head, place the forehead strap 31 on the forehead, and pull the ends of the elastic fastener 3 outwards to tighten both the forehead strap 31 and the face strap 32, pressing the mask firmly against the face. After wearing, the first and second head straps of the head-mounted fastener 1 form a stable triangular structure with the forehead strap 31, and the head-mounted fastener 1 also forms a stable triangular structure with the two face straps 32, thus firmly securing the mask to the patient's face. The oxygen mask / gas mask headband described in this embodiment is easy to wear, provides a more secure and stable fixation, and allows for easy adjustment of tightness. Its overall structure is simple, its manufacturing cost is low, and it is suitable for widespread application.

[0031] Example 3

[0032] Based on Example 1, to further increase the stability of the mask fixation, the two ends of the elastic fixing strap 3 pass through the strap buckle 221 and continue to extend outward to form a neck strap 33 that can be fixed at the back of the neck. The two ends of the neck strap 33 are connected from the back of the patient's neck, which can assist the face strap 32 in pressing the mask tightly against the patient's face and prevent the mask from slipping off.

[0033] There are several ways to connect the two ends of the neck strap 33. You can set hook and loop fasteners 4 at both ends. That is, set a hook side at one end of the elastic fixing strap 3 and a rough side at the other end. The connection between the two ends is achieved by hook and loop fasteners 4. The tightness can be adjusted by adjusting the position of the hook and loop fasteners.

[0034] In addition, quick-connect buckles 5 can be set at both ends of the elastic fixing strap 3 to achieve quick assembly and disassembly. The quick-connect buckles 5 can be set as backpack slots, seat belt slots, or other structures. Figure 2 , Figure 3As shown, the quick-connect buckle 5 in this embodiment includes a male buckle 51 and a female buckle 52. The male buckle 51 includes a male buckle plate 511, which has a through hole and a pressure plate 53 covering the through hole. One end of the pressure plate is integrally connected to the male buckle plate, and the other end is a free end. A hook 512 is provided at the lower end of the male buckle plate 511. The female buckle 52 includes a female buckle plate 521, which has a through hole and a pressure plate 53 covering the through hole. A hanging ring 522 matching the hook 512 is provided at the lower end of the female buckle plate 521. After the two ends of the elastic fixing band 3 are inserted into the through hole of the male buckle plate 511 or the female buckle plate 521, they are adjusted to a suitable position and pressed and fixed by the pressure plate 53, thus completing the installation. To prevent the elastic fixing band 3 from slipping off, serrations are provided on the free end of the pressure plate, as well as on the inner sides of the through holes of the male buckle plate 511 and the female buckle plate 521. When the pressure plate presses the elastic fixing band into the through hole, the serrations can grip the elastic fixing band tightly, preventing it from shifting or falling off. The hook 512 of the male buckle 51 is hung in the hanging ring 522 of the female buckle 52, allowing for convenient and quick connection. To ensure a close fit between the male buckle 51 and the female buckle 52, a groove 513 is provided at the lower end of the male buckle 51, while a protrusion 523 is provided at the upper end of the female buckle 52 to engage with the groove 513. The outer diameter of the protrusion 523 is slightly larger than the inner diameter of the groove 513, enabling a detachable connection. (Serrations added)
