The device also includes: an inflation part located within the mask frame; a fixing part disposed on the two connecting blocks; the inflation part includes a deformable component installed within the mask frame; and a compression component disposed outside the front connecting block. The deformable component includes a receiving groove on the left side of the mask frame, with two mounting blocks fixedly connected to the inner wall of the receiving groove. An airbag is disposed within the receiving groove. Two mounting slots are formed on the outer wall of the airbag, each fixedly connected to one of the two mounting blocks. The two connecting blocks are mirror images of each other. The airbag is a silicone annular air bag.
[0007] Furthermore, the fixing part includes a connecting component, which is mounted on two connecting blocks; and a binding component, of which two are provided, both of which are located on the left side of the mask frame and are arranged in an array.
[0008] Furthermore, the compressed air assembly includes a flexible tube fixedly connected to the inner wall of the mask frame. The end of the flexible tube away from the mask frame is connected to a hollow rubber sleeve. A flow element is provided on the hollow rubber sleeve. The flexible tube extends into the receiving groove on the side near the mask frame and communicates with the airbag. The flow element includes a one-way valve one fixedly connected to the inner wall of the hollow rubber sleeve, and a one-way valve two fixedly connected to the inner wall of the flexible tube. The flow direction of one-way valve one is from the outside of the hollow rubber sleeve to the inside of the hollow rubber sleeve, while the flow direction of one-way valve two is from the inside of the hollow rubber sleeve to the inside of the airbag.
[0009] Furthermore, the connecting assembly includes two connecting blocks two respectively disposed on two connecting blocks one, and a fixing strap is fixedly connected to the two connecting blocks two. Each of the two connecting blocks two has a hole on the side near the two connecting blocks one, and this hole is used to allow the connecting block two to be installed on the connecting blocks one.
[0010] Furthermore, the binding assembly includes a fixing strap fixedly connected to the outer wall of the fixing strap, a limiting rod fixedly connected to the inner wall of the fixing strap, and an adhesive component provided outside the fixing strap. The adhesive component includes a Velcro patch fixedly connected to the rear side of the fixing strap, and a Velcro thread patch fixedly connected to the rear side of the fixing strap. The Velcro patch is located below the Velcro thread patch, and the Velcro patch and the Velcro thread patch are compatible.
[0011] Furthermore, the mask frame, air inlet tube, and connecting block described in this application are all made of medical-grade high-transparency soft polyvinyl chloride and are integrally molded. This material is resistant to disinfection, has good biocompatibility, and is non-irritating when in contact with the human body, making it suitable for the structure and usage requirements of critical care breathing masks.
[0012] Furthermore, the connecting block 2 and the limiting rod described in this application are both made of medical-grade ABS engineering plastic, which has high strength, high toughness and impact resistance, can withstand the tension of the strap and the external force of operation, and is not easy to break or deform.
[0013] Furthermore, the airbag and tubing described in this application are made of medical-grade food-grade silicone, which has excellent biocompatibility, is soft and elastic, fits the patient's face without irritation or allergy, greatly improves wearing comfort, and is also resistant to high temperatures and disinfection, and has good resilience.
[0014] Furthermore, the hollow rubber pouch described in this application is made of medical-grade natural rubber, which has excellent elasticity and resilience, and can quickly return to its original position after being pressed, meeting the operational requirements of repeated pressing and air intake of the air compressor.

[0015] This utility model has the following beneficial effects:
[0016] 1. By setting up an inflation section, during use, the gas is delivered in one direction by pressing and resetting the air compressor. External gas enters the air compressor through one-way valve one, and the gas generated by pressing flows into the air bladder of the deformable component through another one-way valve two. By repeatedly operating this action, gas can be continuously delivered into the air bladder, causing it to gradually expand. This allows the air bladder to expand and deform, gradually adapting to the face shape of critically ill patients, so that the air bladder fits snugly against the patient's face. This not only achieves the anti-dislodgement effect of the breathing mask at the facial contact level, but also improves the comfort of the patient. At the same time, it can adapt to various face shapes, increasing the adaptability and practicality of the breathing mask.
[0017] 2. After inflation, the fixing part is set up. First, the fixing strap is installed on the mask frame by connecting block 2 and connecting block 1 of the connecting component. Then, the fixing strap is wrapped around the patient's head to complete the basic binding. Then, the bottom end of the fixing strap of the binding component is passed through the limiting rod and pulled around the rod. The fixing strap with Velcro is folded down so that the Velcro and Velcro are glued to each other, so that the fixing strap forms a ring structure. This completes the fixing of the air compressor. The air compressor can be fixed at the strap by the binding component to prevent the air compressor from shaking and affecting the use, reduce its space occupation, and make the overall fixing structure more stable.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 As shown, this utility model is a respirator for critically ill patients, including a mask frame 101 and an air inlet tube 102 connected to the right side of the mask frame 101. Two connecting blocks 103 are fixedly connected to the outer wall of the mask frame 101. It also includes an inflation part 2, which is located inside the mask frame 101; and a fixing part 3, which is disposed on the two connecting blocks 103.
[0029] The inflation unit 2 includes a deformable component 21, which is installed inside the mask frame 101; and a compression component 22, which is located outside the front connecting block 103. The deformable component 21 includes a receiving groove 211 on the left side of the mask frame 101, with two mounting blocks 212 fixedly connected to the inner wall of the receiving groove 211. An airbag 213 is disposed inside the receiving groove 211, and two mounting grooves 214 are formed on the outer wall of the airbag 213. The two mounting grooves 214 are fixedly connected to the two mounting blocks 212 respectively. The two connecting blocks 103 are mirror images of each other. The airbag 213 is an air ring made of silicone material. The compression component 22 includes a flexible tube 221 fixedly connected to the inner wall of the mask frame 101. The end of the flexible tube 221 away from the mask frame 101 is connected to a hollow rubber bag 222. The mask is equipped with a flow-through component. The flexible tube 221 extends from the side of the mask frame 101 into the receiving groove 211 and communicates with the airbag 213. The flow-through component includes a one-way valve 223 fixedly connected to the inner wall of the hollow rubber pack 222, and a one-way valve 224 fixedly connected to the inner wall of the flexible tube 221. The flow direction of the one-way valve 223 is from the outside of the hollow rubber pack 222 to the inside of the hollow rubber pack 222, while the flow direction of the one-way valve 224 is from the inside of the hollow rubber pack 222 to the inside of the airbag 213. By setting the inflation part 2, the airbag 213 can expand and deform, gradually adapting to the face shape of critically ill patients, so that the airbag 213 fits the patient's face. This not only achieves the anti-dislodgement effect of the breathing mask from the facial contact level, but also improves the comfort of the patient wearing it. At the same time, it can adapt to various face shapes, increasing the adaptability and practicality of the breathing mask.
[0030] The fixing part 3 includes a connecting component 31, which is mounted on two connecting blocks 103; and a binding component 32, of which two are provided, both of which are located on the left side of the mask frame 101 and are arranged in an array. The connecting component 31 includes two connecting blocks 311 respectively mounted on the two connecting blocks 103, and fixing straps 312 are fixedly connected to the two connecting blocks 311. Each of the two connecting blocks 311 has a hole on the side near the two connecting blocks 103 for mounting the connecting blocks 311 on the connecting blocks 103. The binding component 32 includes a fixing connection. The fixing strap 321 on the outer wall of the fixing strap 312 has a limiting rod 322 fixedly connected to the inner wall of the fixing strap 321. The fixing strap 321 is provided with an adhesive component, which includes a Velcro patch 323 fixedly connected to the rear side of the fixing strap 321. A Velcro patch 324 is fixedly connected to the rear side of the fixing strap 321. The Velcro patch 323 is located below the Velcro patch 324 and the Velcro patch 323 is compatible with the Velcro patch 324. By setting the fixing part 3, the air compressor 22 can be fixed to the strap 312 by the binding component 32, which can prevent the air compressor 22 from shaking and affecting its use, reduce its space occupation, and make the overall fixing structure more stable.
[0031] One specific application of this embodiment is as follows: When in use, the mask frame 101 can be placed over the patient's mouth and nose. At this time, the side of the airbag 213 away from the mask frame 101 will cover the patient's face. Then, medical staff can use the fixing straps 312 to tie the mask to the patient's head for fixation.
[0032] After fixation, due to the patient's face shape, there may be some areas where the airbag 213 is not in contact with the patient's face. At this time, medical staff can continuously press and release the hollow rubber bag 222. Pressing will flatten it and produce elastic deformation. During the flattening process of the hollow rubber bag 222, the space inside the hollow rubber bag 222 is compressed, and the air is squeezed out. Since the one-way valve 223 only allows air to enter the hollow rubber bag 222 from the outside, the squeezed air will only flow into the hose 221. This air will then flow into the hose 224 through the other one-way valve. Inside the airbag 213, when the hollow rubber bag 222 is released, the hollow rubber bag 222 will return to its original position under its own elastic force, thereby restoring the volume of the space inside the hollow rubber bag 222. However, since the one-way valve 224 only allows air to flow into the airbag 213 from the hose 221, the air inside the airbag 213 cannot be drawn into the hollow rubber bag 222. At this time, outside air will flow into the hollow rubber bag 222 through the one-way valve 223. By repeatedly pressing, the airbag 213 can expand and deform, gradually adapting to the patient's face shape.
[0033] After fitting, stop pressing the hollow rubber bag 222 and pinch it tightly. Then pull the hollow rubber bag 222 into the two fixing straps 321. Next, pull up the end of the fixing strap 321 and pass it through the bottom of the limiting rod 322, then pull it out from the top. Then pull it forward around the limiting rod 322. At this time, the Velcro 324 on the fixing strap 321 will pass through the limiting rod 322, while the Velcro 323 will not. Then, fold the fixing strap 321 that is pulling the Velcro 324 downward. In this way, the fixing strap 321 will be attached to the Velcro 323 around the limiting rod 322. Since the Velcro 324 and the Velcro 323 are compatible, the fixing strap 321 will be glued into a ring, thereby fixing the hollow rubber bag 222 to the fixing strap 312.
