[0002] A laryngeal mask airway is a high-success-rate placement tool. Its outer end can be connected to a ventilator or anesthesia machine. The ventilation mask needs to be inserted into the oral cavity to a certain depth, and it is important to prevent it from falling further. After insertion, it needs to be secured with tape. Summary of the Invention

[0003] This utility model provides a multifunctional, non-inflatable throat mask.

[0004] The technical solution of this utility model is implemented as follows: A multifunctional non-inflatable throat mask includes a main tube and a non-inflatable airbag. A corrugated tube is inserted into the opening of the main tube. The two ends of the corrugated tube are respectively connected to a proximal connecting tube and a distal connecting tube. Several slots are opened on the inner wall of the opening of the main tube. A protrusion is provided on the outside of the proximal connecting tube. The protrusion cooperates with the slot. A mouthguard is fitted on the outside of the main tube. A limiting plate is fixedly connected to the side of the mouthguard near the chin. A fixing device is provided on the mouthguard.

[0005] The dental pad is made of silicone.

[0006] The fixing device includes a fixing band with a through hole in the middle. The dental pad passes through the through hole of the fixing band and is fixedly connected to it. Both sides of the fixing band are extension bands with a V-shaped structure. The ends of the extension bands are fixedly connected to fixing parts. Adhesive is provided on one side of the fixing part, and release paper is connected to the side of the adhesive.

[0007] A gastric juice suction tube is connected to one side of the inside of the main tube. One end of the gastric juice suction tube extends to the outside of the main tube. A gastric juice hole is opened on the front end of the non-inflatable bladder cover, and the gastric juice hole is connected to the gastric juice suction tube.

[0008] The gastric fluid suction tube has a one-way valve connected to one end of its external extension.

[0009] The technical solution of this utility model has the following positive effects: A corrugated tube is inserted into the opening of the main tube of this utility model. The corrugated tube and the main tube are engaged by a slot and a protrusion. The angle of the corrugated tube can be adjusted at will, but it can ensure that the connection between the corrugated tube and the main tube will not rotate. A mouthguard is fitted on the outside of the main tube. The limiting plate on the mouthguard plays a limiting role. A fixing device is provided on the mouthguard. The extension bands on both sides are located on the face. After peeling off the release paper, the adhesive side of the fixing part is attached to the face to play a fixing role.

[0012] Figure 3 This is a top view of the inlet of the main tube.

[0013] Figure 4 This is a schematic diagram of the fixing device. Detailed Implementation

[0014] like Figure 1-4 As shown, a multifunctional non-inflatable laryngeal mask includes a main tube 1 and a non-inflatable cuff 2. A corrugated tube 3 is inserted into the opening of the main tube 1. The two ends of the corrugated tube 3 are respectively connected to a proximal connecting tube 4 and a distal connecting tube 5. Several slots 6 are formed on the inner wall of the opening of the main tube 1. A protrusion 7 is provided on the outside of the proximal connecting tube 4, and the protrusion 7 cooperates with the slots 6. A bite pad 8 is fitted on the outside of the main tube 1. A limiting plate 9 is fixedly connected to the side of the bite pad 8 near the chin. A fixing device is provided on the bite pad 8. Specifically, when one end of the non-inflatable cuff 2 is inserted into the pharyngeal airway, the bite pad 8 can increase the comfort when the teeth are clenched. At the same time, the limiting plate 9 is located outside the mouth and limits the insertion depth to prevent it from going deeper. The corrugated tube 3 can be adjusted to different angles to facilitate head surgery without causing any interference. The fixing device fixes the main tube 1 to prevent it from moving around.

[0015] The dental pad 8 is made of silicone. Specifically, the inner diameter of the dental pad 8 is slightly smaller than the outer diameter of the outer end of the main tube 1, so that the dental pad 8 will not move up and down. If it is necessary to adjust the position of the limiting plate 9, pull the dental pad 8 forcefully to move it slightly.

[0016] The fixing device includes a fixing strap 10, with a through hole in the middle. The dental pad 8 passes through the through hole and is fixedly connected to it. Both sides of the fixing strap 10 are V-shaped extension straps 17, and each end of the extension strap 17 is fixedly connected to a fixing part 11. Adhesive 12 is provided on one side of the fixing part 11, and release paper 13 is attached to the side of the adhesive 12. Specifically, as shown... Figure 1 As shown in the diagram, the fixing strap 10 is fixed to the upper part of the dental pad 8, as... Figure 4 As shown, the extension strips 17 on both sides are located on the face. After peeling off the release paper 13, the adhesive side of the fixing part 11 is attached to the face to fix it in place.

[0017] A gastric juice suction tube 14 is connected to one side inside the main tube 1. One end of the gastric juice suction tube 14 extends to the outside of the main tube 1. A gastric juice hole 15 is opened on the front end of the non-inflatable bladder cover 2. The gastric juice hole 15 is connected to the gastric juice suction tube 14. A one-way valve 16 is connected to the outside end of the gastric juice suction tube 14. Specifically, the one-way valve 16 is connected to a syringe to realize the suction of gastric juice.
