[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides an inflatable non-invasive ventilator mask, including a breathing mask 1 and an air bag 2. An inflation / deflation mechanism 3 is provided inside the sides of the breathing mask 1 and the air bag 2. A support mechanism 4 is provided on the sides of the breathing mask 1 and the air bag 2. The inflation / deflation mechanism 3 includes two connecting tubes 301, each fixedly connected to the inside of the sides of the breathing mask 1 and the air bag 2. A support plate 302 is fixedly connected to the bottom of the inner cavity of the connecting tube 301. A fixing ring 303 is fixedly connected to the middle of the inner cavity of the connecting tube 301. A rubber ring 304 is fixedly connected to the top of the inner cavity of the connecting tube 301. A support plate 302 is provided on the top surface of the support plate 302. Multiple vents 305 are evenly distributed on the top surface of the support plate 302. A support tube 306 is fixedly connected to the top surface of the support plate 302. A return spring 307 is fixedly connected to the top surface of the support plate 302. The return spring 307 is sleeved on the side of the support tube 306. A sealing block 308 is fixedly connected to one end of the return spring 307. A sealing gasket 309 is fixedly connected to the side of the sealing block 308. Both the sealing block 308 and the sealing gasket 309 are movably connected to the bottom surface of the fixing ring 303. A top tube 310 is fixedly connected to the middle of the top surface of the sealing block 308. Multiple vents 311 are provided on the side of the top tube 310.

[0027] In this embodiment, the connecting tube 301 connects to the breathing mask 1 and the airbag 2, allowing for the replenishment and release of gas inside the breathing mask 1 and the airbag 2. The support plate 302 is connected to the sealing block 308 via a return spring 307. The sealing block 308 is connected to the fixing ring 303 to seal the connecting tube 301, thus preventing gas leakage from the breathing mask 1 and the airbag 2. The support plate 302 is connected to the support tube 306 to support the return spring 307, increasing the stability of the return spring 307 in supporting the sealing block 308. The sealing gasket 309 is connected to the sealing block 308, improving the tightness of the connection between the sealing block 308 and the fixing ring 303, thereby improving the sealing effect of the sealing block 308 on the connecting tube 301.

[0031] Example 3

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, an adjusting block 408 is movably connected to the back of one end of the connecting plate 405, a stud 409 is fixedly connected to the front of the adjusting block 408, the stud 409 is movably connected to the stud groove 406, a slider 410 is fixedly connected to the front of the adjusting block 408, the slider 410 is slidably connected inside the slider groove 407, a nut 411 is threadedly connected to the side of one end of the stud 409, a nut 412 is threadedly connected to the inside of the front of the adjusting block 408, there are two nuts 412 and they are symmetrically distributed on both sides of the front of the adjusting block 408, an adjusting plate 413 is rotatably connected to one end of the two nuts 412, a second strap ring 414 is fixedly connected to the side of the adjusting block 408, there are two strap rings 414, and a second strap ring 415 is movably connected inside the strap ring 414.

[0033] In this embodiment, the airbag 2 is fixed by connecting the adjusting plate 413 to the airbag 2. The adjusting block 408 is pulled according to the distance between the patient's mouth / nose and forehead, causing the stud 409 and slider 410 to move in the stud groove 406 and slider groove 407 respectively. The adjusting block 408, through the nut 412 and adjusting plate 413, raises and lowers the airbag 2 to adjust its height. After the airbag 2 reaches the appropriate position, the nut 411 is rotated. The nut 411 connects to the stud 409.

If there is still a certain gap between the airbag 2 and the patient's forehead, rotate the two nuts 412. The nuts 412 are connected to the adjusting block 408 and adjusting plate 413. When the nuts 412 rotate, they drive the adjusting plate 413 and the airbag 2 to move towards the patient's forehead, so that the airbag 2 can be attached to the patient's forehead.

[0034] The working principle of this inflatable non-invasive ventilator mask will be explained in detail below.

[0035] like Figure 1-5As shown, the mask 1 is fixed by connecting the mask slot 401 to the breathing mask 1, and the adjusting plate 413 is fixed by connecting the airbag 2. The adjusting block 408 is pulled according to the distance between the patient's mouth / nose and forehead, causing the stud 409 and slider 410 to move in the stud slot 406 and slider slot 407 respectively. The adjusting block 408, through the nut 412 and adjusting plate 413, raises and lowers the airbag 2 to adjust its height. After the airbag 2 reaches the appropriate position, the nut 411 is rotated. The nut 411 is connected to the stud 409. When the nut 411 is rotated to be in close contact with the connecting plate 405, the height of the adjusting block 408 is fixed, thus fixing the position of the airbag 2. The mask slot 401 is then placed over the patient's mouth and nose and pulled... Two straps 404 and 415 are used to wrap around the patient's head. Both ends of straps 404 and 415 are secured with Velcro. The Velcro on straps 404 and 415 is then fastened. Straps 404, through strap loops 403 and mask slots 401, place the breathing mask 1 over the patient's mouth and nose. Straps 415, through strap loops 414, adjusting block 408, nuts 412, and adjusting plate 413, move the airbag 2 to the patient's forehead. If there is still a gap between the airbag 2 and the patient's forehead, the nuts 412 are rotated. Nuts 412 are connected to adjusting block 408 and adjusting plate 413. Rotating nuts 412 moves the adjusting plate 413 and... The air bag 2 moves towards the patient's forehead to fit snugly against it. Connecting the gas delivery tube 402 to the ventilator allows oxygen to be supplied to the patient via the gas delivery tube 402 and the breathing mask 1. The connecting tube 301 connects to the breathing mask 1 and the air bag 2, allowing for the replenishment and release of gas within these components. The support plate 302 is connected to the sealing block 308 via a return spring 307. The sealing block 308 is connected to the fixing ring 303 to seal the connecting tube 301, preventing gas leakage from the breathing mask 1 and the air bag 2. The support plate 302, connected to the support tube 306, supports the return spring 307, increasing the stability of the return spring 307's support for the sealing block 308. The sealing gasket 309 connects to the sealing block 308, improving... The tightness of the connection between the sealing block 308 and the fixing ring 303 improves the sealing effect of the sealing block 308 on the connecting tube 301. When replenishing or venting the gas inside the breathing mask 1 and the air bag 2, the injection end of the syringe is inserted into the connecting tube 301. The rubber ring 304 contacts the injection section of the syringe to prevent gas leakage from the breathing mask 1 and the air bag 2 when the syringe replenishes or vents the gas inside the breathing mask 1 and the air bag 2. Pushing the injection section of the syringe causes the injection section to press against the top tube 310, and through the top tube 310, it drives the sealing block 308 and the sealing gasket 309 to disengage from the fixing ring 303. When the sealing block 308 descends, it causes the return spring 307 to contract. The descent of the sealing block 308 connects the two ends of the connecting tube 301.Pushing or pulling the syringe allows air to be replenished and expelled from the breathing mask 1 and air bag 2 through air vent 2 311 and air vent 1 305. Changing the gas volume inside the breathing mask 1 and air bag 2 allows them to better fit the patient's face, improving patient comfort and preventing pressure injuries to the patient's face.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
