[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 3 As shown, an anesthesia breathing mask according to an embodiment of the present invention includes a mask body 1 and a fitting component 2. The outer wall of the mask body 1 is fixedly mounted with a support seat 5. The fitting component 2 includes a base 201. The bottom of the support seat 5 is fixedly connected to the top of the base 201. The bottom of the base 201 is fixedly mounted with an elastic fitting pad 202. The inner wall of the base 201 is fixedly mounted with a magnet ring 203. The bottom of the magnet ring 203 is evenly fixedly mounted with a plurality of telescopic connecting columns 204. The ends of the plurality of telescopic connecting columns 204 away from the magnet ring 203 are all fixedly mounted with magnet blocks 205. The mask body 1 is covered on At the mouth and nose of the patient, when the device contacts the patient's face, the telescopic connecting column 204 will contract due to the pressure brought by the patient's face. The telescopic connecting columns 204 located at different positions will contract to different degrees due to the facial curve of the patient, thereby automatically adapting to the contour of the patient's face. When the telescopic connecting column 204 contracts, the magnet block 205 will approach the magnet ring 203, and the magnet ring 203 will repel the magnet block 205 under the action of magnetic force, thereby pushing the magnet block 205 toward the patient's face. Under the action of magnetic force, the device is kept in close contact with the patient's face, thereby enhancing the sealing of the device.

[0035] like Figures 3 to 5As shown, a filling component 3 is provided on one side of the elastic fitting pad 202, and the filling component 3 includes an airbag 301 and a pad 302. The airbag 301 is fixedly installed on the outer wall of the elastic fitting pad 202, and an airbag 303 is fixedly installed on the inner wall of the pad 302. A pressure plate 304 is slidably installed on the inner wall of the pad 302. An air guide tube 305 is symmetrically fixedly installed between the inner wall of the airbag 303 and the inner wall of the airbag 301, and the inner wall of the pad 302 is fixedly connected to the outer wall of the air guide tube 305. When the device is worn, the pad 302 is located at the back of the patient's head. When the patient lies down, When the patient's head is inhaled, the pressure plate 304 is pressed by the patient's head, and the pressure plate 304 generates pressure on the airbag 303. After the airbag 303 is squeezed by the pressure, the air inside is transported to the inside of the airbag 301 through the air duct 305. The airbag 301 expands and fits tightly against the patient's facial skin, thereby further increasing the sealing performance. Since the patient's head always generates pressure on the airbag 303, the airbag 301 always remains filled, thereby ensuring that the airbag 301 always fits against the patient's face, and gas leakage can be effectively avoided during use.

[0036] like Figures 5 to 9 As shown, an adjustment component 4 is arranged on the inner side of the pad 302, and the adjustment component 4 includes an adjustment slide A401 and an adjustment slide B402. The adjustment slide A401 and the adjustment slide B402 are both slidably connected to the inner wall of the pad 302. There are two adjustment slides A401 and B402. A lifting seat 403 is arranged above the adjustment slide A401 and the adjustment slide B402. A telescopic support column 404 is slidably installed on the inner wall of the lifting seat 403. An elastic member 405 is arranged on the outer side of the telescopic support column 404. A connecting rod 406 is fixedly installed between the outer walls of the corresponding adjustment slides A401 and the adjustment slide B402. An adjustment rod 407 is fixedly installed between the outer walls of the two adjustment slides A401. The adjustment rod 4 The inner wall of 07 is threadedly connected with a traveling screw 408; when the traveling screw 408 is rotated, the traveling screw 408 will drive the adjusting rod 407 to move under the action of the thread, and when the adjusting rod 407 moves, the adjusting slide A401 and the adjusting slide B402 will move synchronously under the action of the connecting rod 406, and when the adjusting slide A401 and the adjusting slide B402 move, the lifting seat 403 will be driven to rise and fall, and the degree of squeezing of the elastic member 405 can be changed by lifting and lowering the lifting seat 403, so that the elastic member 405 is in different compression degrees, and when the compression degree of the elastic member 405 changes, the supporting strength of the elastic member 405 on the pressure plate 304 will also change accordingly, so that the equipment can be adjusted accordingly according to the pressure generated by the heads of different patients.

[0037] like Figures 2 to 3As shown, the magnet ring 203, the telescopic connecting column 204 and the magnet block 205 are located between the base 201 and the elastic fitting pad 202. The magnet ring 203 and the magnet block 205 magnetically repel each other, and the outer wall of the magnet block 205 conflicts with the inner wall of the elastic fitting pad 202; the telescopic connecting column 204 and the magnet block 205 support the elastic fitting pad 202. When the device contacts the patient's face, the telescopic connecting column 204 contracts to make the elastic fitting pad 202 deform accordingly to adapt to the patient's facial contour, and the magnet ring 203 generates thrust to the magnet block 205 through magnetic force, thereby keeping the device in contact with the patient's face.

[0038] like Figure 4 As shown, a flexible pillow 306 is fixedly installed on the top of the pressing plate 304 ; the flexible pillow 306 can increase the comfort of the patient's head when it is pressed on the pressing plate 304 .

[0039] like Figure 5 As shown, a ventilation tube 307 is fixedly installed on the inner wall of the air bag 303, and the ventilation tube 307 passes through the inner wall of the pad 302. The end of the ventilation tube 307 away from the air bag 303 is threadedly connected with a ventilation valve 308; the ventilation valve 308 can be removed by rotating the ventilation valve 308 to put the ventilation tube 307 in an open state, and the gas inside the air bag 303 can be discharged through the ventilation tube 307, and new gas is injected into the air bag 303 through the ventilation tube 307, and then the ventilation valve 308 is re-installed on the ventilation tube 307 to seal the ventilation tube 307, thereby achieving the effect of replacing the gas inside the air bag 303.

[0040] like Figures 5 to 7 As shown, one end of the telescopic support column 404 is fixedly connected to the inner wall of the pad 302, and the other end of the telescopic support column 404 is fixedly connected to the bottom of the pressing plate 304. One end of the elastic member 405 is fixedly connected to the top of the lifting seat 403, and the other end of the elastic member 405 is fixedly connected to the bottom of the pressing plate 304. The telescopic support column 404 limits the pressing plate 304, and the elastic member 405 supports the pressing plate 304.

[0041] like Figures 5 to 9As shown, one end of the traveling screw 408 passes through the pad 302 and is fixedly installed with an adjusting knob 409, and a support 410 is fixedly installed on the inner wall of the pad 302. The end of the traveling screw 408 away from the adjusting knob 409 is rotatably connected to the inner wall of the support 410. An inclined groove 411 is provided at the bottom of the lifting seat 403, and the adjusting slide A401 and the adjusting slide B402 are slidably connected to the lifting seat 403 through the inclined groove 411; the traveling screw 408 can be driven to rotate by rotating the adjusting knob 409, and the setting of the adjusting knob 409 is to facilitate the rotation of the traveling screw 408. The support 410 supports the traveling screw 408 to increase the stability of the traveling screw 408, and the height of the lifting seat 403 is adjusted by the cooperation of the arranged inclined groove 411 with the adjusting slide A401 and the adjusting slide B402.

[0042] like Figure 1 to Figure 2 As shown, an air inlet pipe 6 is fixedly installed on the inner wall of the top of the mask body 1, a connecting sleeve 7 is fixedly installed on the inner wall of the side of the mask body 1, and an exhaust pipe 8 is threadedly connected to the inner wall of the connecting sleeve 7; the air inlet pipe 6 and the exhaust pipe 8 are connected to the external pipeline, anesthetics or oxygen are delivered to the patient through the air inlet pipe 6, and the generated waste gas is discharged through the exhaust pipe 8.

[0043] like Figure 1 As shown, a bracket 9 is fixedly installed on the top of the mask body 1, and a plurality of columns 10 are fixedly installed on the top of the bracket 9. Elastic straps 11 are symmetrically arranged on the top of the bracket 9, and both ends of the elastic straps 11 are fixedly connected to the outer wall of the pad 302; through the cooperation of the bracket 9 and the column 10, the elastic straps 11 are limited so that the elastic straps 11 can fix the device on the patient's face, and the two ends of the elastic straps 11 are connected through the pad 302. After the device is worn, the pad 302 is located at the back of the patient's head, and the patient can squeeze the pressure plate 304 inside the pad 302 to increase the sealing when lying down.

[0044] Working principle: When in use, first cover the mask body 1 on the patient's face so that the mask body 1 seals the patient's mouth and nose, and at the same time place the pad 302 on the back of the patient's head, and fix the mask body 1 with the elastic strap 11. When the mask body 1 is covered on the patient's face, the elastic fitting pad 202 will be subjected to the pressure brought by the patient's face, causing the telescopic connecting column 204 to contract. Each telescopic connecting column 204 will adapt to the patient's facial contour through different degrees of contraction. When the telescopic connecting column 204 contracts, the magnet block 205 will approach the magnet ring 203, and the magnet ring 203 will repel the magnet block 205 under the action of magnetism, so that the magnet block 205 is against the elastic fitting pad 202 to ensure the fit of the device. When the patient lies down, the patient's head will squeeze the pressure plate 304, and the pressure plate 304 will squeeze the air bag 303. The gas in the air bag 303 will enter the air bag 301 through the air guide tube 305, and the air bag 301 will expand, thereby further improving the fit of the device. For different patients, the adjustment rod 407 is driven to move by rotating the travel screw 408. When the adjustment rod 407 moves, it will drive the adjustment slide A401 and the adjustment slide B402 to move, so as to adjust the height of the lifting seat 403. When the height of the lifting seat 403 changes, the degree of compression of the elastic member 405 will also change accordingly, and then the support force on the pressure plate 304 will be changed, so as to achieve the effect of adjusting the pressure generated by the heads of different patients accordingly.
