The buffer mechanism 2 includes a mounting ring 201, and the mounting ring 201 is fixedly connected to the inner surface of the mask body 1 near the middle position. The rear surface of the mounting ring 201 is equidistantly fixedly connected with a plurality of dampers 202, and the outer sleeve of the damper 202 is provided with a spring 203. An annular plate 204 is fixedly connected between the rear end faces of the dampers 202, an insert plate 205 is fixedly connected to the front surface of the annular plate 204 near the outer edge, the outer surface of the insert plate 205 is in contact with the inner surface wall of the movable groove 13, the front surface of the mask body 1 is fixedly connected to the oxygen interface 12, the outer surfaces of both sides of the mask body 1 are symmetrically fixedly connected to the first buckles 11 near the bottom, the rear surface of the annular plate 204 is bonded to the patch pad 206, and the top of the mask body 1 is fixedly connected to the connecting frame 3.
其整个实施例1达到的效果为，当慢阻肺患者使用无创呼吸机过程中需要将面罩本体1固定在面部时，通过将调节带连接在第一搭扣11上，然后将面罩本体1按压在面部后通过调节带进行固定，当面罩本体1按压在面部时，贴敷垫206采用医用硅胶材料制成，厚度较厚，受到挤压后产生形变并与脸部皮肤紧密贴合，并挤压环形板204向面罩本体1方向移动，此时将面罩本体1环形板204前表面的插板205向活动槽13的深处移动后，此时插板205起到将面罩本体1内外气体进行隔绝的作用，使用合适的力度将面罩本体1按压在脸部后保持较为松弛的状态后，通过调节带对面罩本体1进行固定，此时安装环201上的弹簧203产生挤压力推动环形板204向脸部方向移动，使得贴敷垫206始终保持与脸部紧贴的作用，环形板204活动时，插板205在活动槽13内部滑动不会发生脱离，进而确保了对内部气体的隔绝效果，并且大大减小了脸部受到的挤压力，解决了脸部受压过度的地方受到刺激而引发皮疹的问题，并且当患者脸部肌肉发生大的运动对环形板204瞬间产生较大的挤压力时，阻尼器202发生缓慢收缩，随后脸部肌肉放松后在弹簧203的作用下发生复位，避免因脸部肌肉运动时对环形板204产生的瞬间挤压力导致环形板204瞬间移位而引发内部气体泄漏的问题，密封效果较好，通过设置氧气接口12起到将面罩本体1与无创呼吸机进行连接并向面罩本体1内部输送气体的作用，通过设置连接架3起到将额头撑块31与面罩本体1进行连接的作用。The effect achieved by the entire embodiment 1 is that when a COPD patient needs to fix the mask body 1 on the face during the use of the non-invasive ventilator, the mask body 1 is fixed to the face by connecting the adjusting belt to the first buckle 11, and then pressing the mask body 1 on the face and fixing it through the adjusting belt. When the mask body 1 is pressed on the face, the patch pad 206 is made of medical silicone material with a relatively thick thickness. After being squeezed, it is deformed and fits tightly to the facial skin, and squeezes the annular plate 204 to move toward the mask body 1. At this time, the plug plate 205 on the front surface of the annular plate 204 of the mask body 1 is moved to the depth of the active groove 13. At this time, the plug plate 205 plays a role in isolating the gas inside and outside the mask body 1. After pressing the mask body 1 on the face with appropriate force and keeping it in a relatively relaxed state, the mask body 1 is fixed through the adjusting belt. At this time, the spring 203 on the mounting ring 201 generates an extrusion force to push the annular plate 204 to move toward the face, so that the patch The pad 206 always keeps in close contact with the face. When the annular plate 204 moves, the plug plate 205 slides in the movable groove 13 without detaching, thereby ensuring the isolation effect of the internal gas and greatly reducing the squeezing force on the face, solving the problem of rashes caused by irritation of excessively compressed areas on the face. When the patient's facial muscles move greatly and instantly generate a large squeezing force on the annular plate 204, the damper 202 contracts slowly, and then resets under the action of the spring 203 after the facial muscles relax, avoiding the problem of internal gas leakage caused by the instantaneous squeezing force on the annular plate 204 caused by the instantaneous displacement of the annular plate 204 during facial muscle movement. The sealing effect is good. The oxygen interface 12 is provided to connect the mask body 1 to the non-invasive ventilator and transport gas to the inside of the mask body 1. The connecting frame 3 is provided to connect the forehead support block 31 to the mask body 1.
实施例2，如图1-图4所示，本实施例与实施例1的区别仅在于，连接架3的后表面靠近顶部的位置固定连接有额头撑块31，额头撑块31的内部横向等距开设有多个横向通气槽32，额头撑块31的内部纵向等距开设有多个纵向通气槽33，额头撑块31的后表面排列开设有多个连通槽34，连通槽34、横向通气槽32和纵向通气槽33相互连通，额头撑块31的两侧外表面对称固定连接有第二搭扣42，额头撑块31的后表面粘合连接有棉垫4，棉垫4的外表面排列开设有多个通孔41，通孔41和连通槽34的位置相对应。Embodiment 2, as shown in Figures 1 to 4, the only difference between this embodiment and embodiment 1 is that a forehead support block 31 is fixedly connected to a position near the top of the rear surface of the connecting frame 3, a plurality of transverse ventilation grooves 32 are equidistantly provided inside the forehead support block 31 in the transverse direction, a plurality of longitudinal ventilation grooves 33 are equidistantly provided inside the forehead support block 31 in the longitudinal direction, a plurality of connecting grooves 34 are arranged on the rear surface of the forehead support block 31, the connecting grooves 34, the transverse ventilation grooves 32 and the longitudinal ventilation grooves 33 are interconnected, a second buckle 42 is symmetrically fixedly connected to the outer surfaces of both sides of the forehead support block 31, a cotton pad 4 is bonded to the rear surface of the forehead support block 31, a plurality of through holes 41 are arranged on the outer surface of the cotton pad 4, and the positions of the through holes 41 and the connecting grooves 34 correspond to each other.
其整个实施例2达到的效果为，额头撑块31表面的第二搭扣42用于安装第二根调节带，通过该调节带起到将额头撑块31固定在患者额头上避免面罩本体1滑落的作用，并且，当额头撑块31固定在患者额头位置后，外部的空气通过额头撑块31顶部漏出的纵向通气槽33和侧面漏出的横向通气槽32进入到额头撑块31内部，并通过后侧的连通槽34进入到额头撑块31和患者额头皮肤贴合位置，使得患者额头上的皮肤可以保持空气畅通，避免引发皮疹等皮肤病，提高了实用性，通过在额头撑块31后表面设置棉垫4起到提高佩戴舒适性的作用，并且棉垫4通气性较高，进一步提高了皮肤表面的通风效果。The effect achieved by the entire embodiment 2 is that the second buckle 42 on the surface of the forehead support block 31 is used to install the second adjustment strap, which plays a role in fixing the forehead support block 31 on the patient's forehead to prevent the mask body 1 from slipping off. Moreover, when the forehead support block 31 is fixed at the patient's forehead, the external air enters the forehead support block 31 through the longitudinal ventilation groove 33 leaking from the top of the forehead support block 31 and the transverse ventilation groove 32 leaking from the side, and enters the forehead support block 31 and the patient's forehead skin fitting position through the connecting groove 34 on the rear side, so that the skin on the patient's forehead can keep the air unobstructed, avoid the occurrence of skin diseases such as rashes, and improve practicality. By arranging a cotton pad 4 on the rear surface of the forehead support block 31, the wearing comfort is improved, and the cotton pad 4 has high air permeability, which further improves the ventilation effect of the skin surface.

When the mask body 1 is pressed on the face, the patch pad 206 is made of medical silicone material with a relatively thick thickness. After being squeezed, it is deformed and fits tightly to the facial skin, and squeezes the annular plate 204 to move toward the mask body 1. At this time, the plug plate 205 on the front surface of the annular plate 204 of the mask body 1 is moved to the depth of the active groove 13. At this time, the plug plate 205 plays a role in isolating the gas inside and outside the mask body 1. After pressing the mask body 1 on the face with appropriate force and keeping it in a relatively relaxed state, the mask body 1 is fixed by the adjusting belt. At this time, the spring 203 on the mounting ring 201 generates an extrusion force to push the annular plate 204 to move toward the face, so that the patch pad 20 6 always keeps close contact with the face. When the annular plate 204 moves, the insert plate 205 slides inside the movable groove 13 without detaching, thereby ensuring the isolation effect of the internal gas and greatly reducing the squeezing force on the face, solving the problem of irritation and rash caused by excessive pressure on the face. After the mask body 1 is installed, the forehead support block 31 is fixed to the patient's forehead by installing another adjustment strap to the second buckle 42 to prevent the mask body 1 from slipping. Moreover, when the forehead support block 31 is fixed to the patient's forehead, the external air enters the forehead support block 31 through the longitudinal ventilation groove 33 leaking from the top of the forehead support block 31 and the transverse ventilation groove 32 leaking from the side, and enters the forehead support block 31 and the patient's forehead skin fitting position through the connecting groove 34 on the rear side, so that the skin on the patient's forehead can keep air unobstructed, avoid causing skin diseases such as rashes, and improve practicality.
