The notch 11 is arranged in the middle of the fixed plate 1, and the notch 11 extends to the upper side edge of the fixed plate 1 on one side. The caliber of the notch 11 is greater than the outer diameter of the dental pad part and less than the outer diameter of the flange, so that the dental pad part can pass through the notch 11 and the flange is prevented from slipping out of the notch 11. After the oropharyngeal airway is successfully placed, the notch 11 is aligned with the dental pad part of the oropharyngeal airway, and the flange of the oropharyngeal airway is abutted with the front surface of the fixed plate 1, so that the oropharyngeal airway is prevented from falling into the oral cavity. Two connecting holes 16 are arranged at the left and right ends of the fixed plate 1. Meanwhile, the fixed plate 1 can be designed as an arc shape, so that the fixed plate 1 can be more fitted to the lips of the patient, the contact area between the fixed plate 1 and the skin is increased, the comfort is improved, and the pressure damage to the skin of the patient is also reduced to a certain extent.

[0026] Referring to the drawings accompanying the specification Figure 2 The fixed band 3 is an elastic band, and a sub-magic tape 31 is fixedly arranged on the outer side of the two ends of the fixed band 3. A mother magic tape 32 is fixedly arranged on part of the outer side of the middle section of the fixed band 3 or on the entire outer side of the middle section of the fixed band 3. After the fixed band 3 passes through the connecting hole 16, the fixed band 3 is folded to detachably bond the sub-magic tape 31 and the mother magic tape 32, so as to fixedly connect the fixed band 3 and the fixed plate 1. The sub-magic tape 31 is attached to the mother magic tape 32 arranged at different positions, so as to adjust the tightness of the fixed band 3. The fixed plate 1 is fixed to the lips of the patient, and the magic tape is designed to facilitate the disassembly of the fixed band 3 and the fixed plate 1.

The decompression sleeve is made of sponge, soft elastic rubber, soft elastic plastic, silica gel or the like. The contact area between the fixed band 3 and the skin is increased, and the pressure damage to the skin of the patient caused by the fixed band 3 is reduced.

[0028] The inventor finds that the fixed plate 1 fixed to the lips of the patient by the fixed band 3 may cause certain pressure to the skin and may cause pressure damage. Therefore, a decompression pad layer 17 is fixedly arranged on the back surface of the fixed plate 1 in contact with the lips of the patient. The decompression pad layer 17 is made of polyester foam dressing, sponge, soft elastic rubber, soft elastic plastic, silica gel or the like. The comfort of the patient is improved to a certain extent, and the formation of pressure damage is prevented.

[0029] Referring to the drawings accompanying the specification Figure 3 , 4The fixed plate 1 is provided with a hinge seat 12, a hinge shaft 13 and a buckling plate 14. The two hinge seats 12 are fixedly arranged on the front surface of the fixed plate 1 at a distance and on the right side of the notch 11. The hinge shaft 13 is fixedly connected between the two hinge seats 12. The buckling plate 14 is fixedly arranged on the front surface of the fixed plate 1 and on the left side of the notch 11. The hinge shaft 13 corresponds to the buckling plate 14. The buckling groove 15 is arranged on the buckling plate 14.

[0030] The hinge block 21 is sleeved on the hinge shaft 13 through the hinge through hole 22, so that the fixed cover 2 can rotate around the hinge shaft 13. The buckling plate 14 is a resilient plate. The end surface of the buckling block 25 is an arc surface. The distance from the hinge through hole 22 to the end surface of the buckling block 25 is greater than the distance from the hinge shaft 13 to the buckling plate 14. When the fixed cover 2 is rotated around the hinge shaft 13 to be buckled and fixed, the front end surface of the buckling block 25 abuts against the side surface of the buckling plate 14 on the side away from the notch 11. With the continuous rotation of the fixed cover 2 around the hinge shaft 13, the buckling plate 14 is continuously pressed, so that the buckling plate 14 is bent towards the side away from the notch 11. Until the buckling block 25 moves to the position of the buckling groove 15 and is clamped into the buckling groove 15. At this time, the front end surface of the buckling block 25 releases the abutment against the side surface of the buckling plate 14 on the side away from the notch 11. Under the action of the resilience of the buckling plate 14 itself, the buckling plate 14 returns to the initial upright state, so that the fixed cover 2 is fixed on the front surface of the fixed plate 1.

[0031] In order to fix the oropharyngeal airway after the fixed cover 2 is buckled and fixed on the front surface of the fixed plate 1, referring to the drawings Figure 4 The clamping groove 23 is arranged on the back surface of the fixed cover 2. The through groove 24 is arranged on the bottom surface of the clamping groove 23 and extends out of the front surface of the fixed cover 2. The outer diameter of the clamping groove 23 is greater than the outer diameter of the through groove 24. The outer diameter of the clamping groove 23 is greater than or equal to the outer diameter of the flange. The outer diameter of the through groove 24 is greater than or equal to the diameter of the air hole arranged on the flange.

[0032] After the fixed cover 2 is buckled and fixed on the front surface of the fixed plate 1, the flange is clamped into the clamping groove 23, so that the oropharyngeal airway cannot be displaced or pulled out. The air hole arranged on the flange is exposed from the through groove 24, so that the patient can breathe normally.

[0033] The method for using the oropharyngeal airway fixator in the patent is as follows: after the oropharyngeal airway is successfully placed, the notch 11 of the fixed plate 1 is aligned with the dental pad part of the oropharyngeal airway and is sleeved into place from bottom to top, and the flange of the oropharyngeal airway abuts against the front surface of the fixed plate 1 (as shown in the drawings Figure 5As shown, when the fixed cover 2 is rotated around the hinge axis 13, the front end face of the fastening block 25 will abut against the side of the fastening plate 14 facing the recess 11. As the fixed cover 2 continues to rotate around the hinge axis 13, it will continuously squeeze the fastening plate 14, causing the fastening plate 14 to bend away from the recess 11 until the fastening block 25 moves to the position of the fastening groove 15 and is engaged in the fastening groove 15. At this time, the front end face of the fastening block 25 releases its abutment against the side of the fastening plate 14 facing the recess 11. Under the action of the fastening plate 14's own elasticity, the fastening plate 14 returns to its initial straight position. In the upright position, the fixing cover 2 is fixed on the front of the fixing plate 1. At this time, the flange is inserted into the snap-fit ​​groove 23, and the ventilation hole opened on the flange is exposed from the through groove 24. The flange is clamped and fixed between the fixing cover 2 and the fixing plate 1. Finally, after passing both ends of the fixing strap 3 through the connecting holes 16 on both sides of the fixing plate 1, the length of the fixing strap 3 is adjusted. The fixing strap 3 is then folded in half to detachably attach the female hook and loop fastener 31 and the female hook and loop fastener 32, thereby achieving a fixed connection between the fixing strap 3 and the fixing plate 1. The fixing plate 1 is then fixed to the patient's lips, thus achieving the fixation of the oropharyngeal airway.

[0034] When it is necessary to change the oropharyngeal airway, medical staff bend the fastening plate 14 away from the notch 11 until the fastening block 25 disengages from the fastening groove 15, and rotate the fixing cover 2 around the hinge axis 13 to open the fixing cover 2, as shown in the instruction manual. Figure 5 In the state shown, the oropharyngeal airway can be removed. Alternatively, separate the female Velcro 31 from the female Velcro 32 at one end of the fixing strap 3, and unconnect the fixing strap 3 to the fixing plate 1. The medical staff can hold the flange with one hand and pull down the fixing plate 1 with the other hand to disengage the dental pad part of the oropharyngeal airway from the notch 11, remove the oropharyngeal airway fixator, and finally remove the oropharyngeal airway. After successfully inserting the new oropharyngeal airway, fix the new oropharyngeal airway using the oropharyngeal airway fixator (the previous oropharyngeal airway fixator can be reused, or a new oropharyngeal airway fixator can be replaced) according to the above method.

[0035] It is obvious that modifications and / or additions can be made to the above-mentioned oropharyngeal airway fixator and corresponding methods without departing from the field and scope of this utility model.

[0036] It is equally clear that, although this utility model has described the oropharyngeal airway fixation device in detail, those skilled in the art will certainly be able to obtain many other equivalent forms of oropharyngeal airway fixation devices and corresponding methods, which have the features described in the claims and are therefore within the scope of protection defined herein.
