[0028] See also Figure 1 to Figure 6, is a cricothyroid ventilation component, including a main trachea 1, the proximal port of the main trachea 1 is a socket 6, and the distal port is provided with a connector 3. The main trachea 1 is provided with a conical plug 2 that can slide along the outer wall of the main trachea 1, and the outer diameter of the conical plug 2 gradually increases along the proximal end of the main trachea 1 pointing to the distal direction. The end of the conical plug 2 close to the distal end of the main trachea 1 is provided with an annular top cavity 8; the present cricothyroid ventilation component also includes a plurality of silicone pads 9 that can be matched and filled in the top cavity 8.

[0029] During the first aid process, after the patient's cricothyroid membrane is incised, one end of the socket 6 on the main trachea 1 of the cricothyroid membrane ventilation assembly is inserted into the trachea to a suitable position, and then the conical plug 2 is slid into the incision until the outer diameter of the conical plug 2 matches the incision, and then an appropriate number of elastic silicone pads 9 are inserted into the top cavity 8. The silicone pads 9 are deformed during the insertion process and are tightly pressed between the inner wall of the top cavity 8 and the outer wall of the main trachea 1, so that the top cavity 8 cannot move relative to the main trachea 1, thereby fixing the conical plug 2 and the main trachea 1 together, and finally connecting the connector 3 to the ventilator to deliver oxygen to the patient. The cricothyroid ventilation assembly is provided with a conical plug 2 that can dynamically match the cricothyroid membrane incision. The conical plug 2 can be relatively fixed in the incision by adjusting the depth of the conical plug 2 inserted into the incision, and the conical plug 2 and the main trachea 1 are relatively fixed by filling with a silicone pad 9, thereby finally achieving the relative fixation of the main trachea 1 in the incision, reducing the probability of the main trachea 1 shaking in the incision due to external factors such as patient agitation during ventilation, thereby reducing the adverse effects of catheter shaking on soft tissues, blood vessels, and nerves near the incision.

[0030] The method of inserting the silicone pad 9 into the top cavity 8 to achieve the relative fixation of the conical plug 2 and the main air pipe 1 has the advantage of convenient and simple operation. However, during use, the silicone pad 9 occasionally pops out of the top cavity 8 to destroy the relative fixation of the conical plug 2 and the main air pipe 1. In order to avoid this situation, Figure 2 , 4As shown, the cricothyroid ventilation assembly is provided with a top cover 10 that can be slidably mounted on the main airway 1, the inner wall of the top cavity 8 is provided with an internal thread, the outer wall of the top cover 10 is provided with an external thread matching the internal thread on the top cavity 8, and the top cavity 8 is filled with a plurality of fan-shaped silicone pads 9, which are continuously spliced ​​to form a circular silicone ring, and when the silicone pads 9 are in a natural state, a gap is left between the inner wall of the silicone ring and the outer wall of the main airway 1; a gap is also left between the inner wall of the top cover 10 and the outer wall of the main airway 1, and the gap is smaller than the gap between the inner wall of the silicone ring and the outer wall of the main airway 1 when the silicone pads 9 are in a natural state. In the above structure, as the screwing depth of the top cover 10 in the top cavity 8 continues to increase, the squeezing force of the top cover 10 on the silicone pad 9 also gradually increases, causing the silicone pad 9 to undergo axial thinning and radial elongation elastic deformation. The silicone pad 9 is tightly pressed between the inner wall of the top cavity 8 and the outer wall of the main air pipe 1, thereby achieving relative fixation of the conical plug 2 and the main air pipe 1.

[0031] In the above structure, the silicone pad 9 can only be fully squeezed if the bottom surface of the top cover 10 and the silicone pad 9 have a considerable contact area. This makes the top cover 10 too thick and heavy, which makes the cricothyroid membrane incision bear too much pressure, increasing the patient's discomfort. In order to avoid this situation, Figure 3 , 4 As shown, as an improvement on the above structure, the cricothyroid ventilation assembly also includes a top cover 10 slidably mounted on the main airway 1, the inner wall of the top cavity 8 is provided with an internal thread, the outer wall of the top cover 10 is provided with an external thread matching the internal thread on the top cavity 8, the top cavity 8 is filled with a plurality of fan-shaped silicone pads 9, the silicone pads 9 are continuously spliced ​​to form a circular silicone ring, and when the silicone pads 9 are in a natural state, a gap is left between the inner wall of the silicone ring and the outer wall of the main airway 1; the thickness of the top cover 10 is equal to the thickness of the top cavity wall, and an annular pressure plate 12 is further provided between the silicone ring and the top cover 10, and the gap between the inner wall of the pressure plate 12 and the outer wall of the main airway 1 is smaller than the gap between the inner wall of the silicone ring and the outer wall of the main airway 1 when the silicone pads 9 are in a natural state. In this structure, as the screwing depth of the top cover 10 in the top cavity 8 increases continuously, the extrusion force applied by the top cover 10 to the silicone pad 9 through the pressure plate 12 also gradually increases, so that the silicone pad 9 undergoes elastic deformation such as axial thinning and radial elongation, and the silicone pad 9 is tightly pressed between the inner wall of the top cavity 8 and the outer wall of the main airway 1, thereby achieving relative fixation of the tapered plug 2 and the main airway 1. In this structure, the silicone pad 9 is fully squeezed by setting the pressure plate 12, so that the thickness and weight of the top cover 10 can be greatly reduced, and the pressure on the cricothyroid membrane incision can be improved.

[0032] In the present cricothyroid ventilation assembly, an airbag 4 is fixedly connected to the outer wall of the main airway 1 near the socket 6, and an inflation tube 11 is connected to the opening of the airbag 4. The inflation tube 11 extends along the outer wall of the main airway 1 to the vicinity of the connector 3. An air nozzle is installed at the end of the inflation tube 11, and the air nozzle is a forward air inlet valve. When using the present cricothyroid ventilation assembly for ventilation, an inflation device is connected to the air nozzle to inflate the airbag 4, which can expand the airbag 4. The airbag 4 abuts against the tracheal wall, which has the functions of internally fixing the main airway 1 and sealing the trachea to prevent ventilation leakage.

[0033] The degree of inflation of the airbag 4 varies. When it is strong, the sealing is good, but the pressure on the tracheal wall is too high, and the tracheal wall will be damaged as the ventilation time increases. When it is weak, the damage to the tracheal wall can be avoided, but the sealing is poor. In the present cricothyroid membrane ventilation assembly, the airbags 4 are provided with two, and the two airbags 4 are each matched and connected with a corresponding inflation tube 11. When working, the two airbags 4 are alternately inflated with high pressure, which has good sealing and can also avoid the damage to the tracheal wall caused by the high pressure for a long time at a certain part of the trachea wall.

[0034] In the present cricothyroid ventilation assembly, the airbag 4 is fixedly connected to the wrapping tube 5, the wrapping tube 5 is fixedly sleeved on the outer wall of the main trachea 1, and the inflation tube 11 matching the airbag 4 passes through the wrapping tube 5, extends from between the wrapping tube 5 and the outer wall of the main trachea 1 and extends along the outer wall of the main trachea 1 to the vicinity of the connector 3.

[0035] In the present cricothyroid ventilation assembly, the port of the inflation tube 11 is equipped with a tee, one of the other two interfaces of the tee is equipped with a gas nozzle, and the other interface is equipped with a barometer. When in use, the airbag 4 is inflated and deflated through the gas nozzle, and the pressure in the airbag 4 is observed through the barometer.

[0036] In the present cricothyroid ventilation assembly, a Murphy port 7 is also provided on the outer wall of the main trachea 1 near the socket 6. The Murphy port 7 and the socket 6 can supply oxygen to the body at the same time and serve as backup for each other. When one of them is blocked by the tracheal wall, oxygen can be supplied through the other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
