Through encircleing aeration component 100 with the gas cell 201 and setting up, when aeration component 100 placed inside patient's laryngeal cavity, the gas cell 201 can seal the separation to the space between aeration component 100 and the larynx wall, and the subassembly 100 of guaranteeing to breathe in about the choke is gaseous can advance out through aeration component 100, and the independent gas cell 201 of aerifing simultaneously can extrude asymmetric larynx wall respectively, and when avoiding patient's laryngeal cavity space asymmetry, gas cell 201 and laryngeal tissue laminating degree descend.
As shown in fig. 1, the inflation assembly 200 further includes inflation tubes 202, the number of the inflation tubes 202 is equal to that of the inflation bags 201, and each inflation bag 201 is communicated with one inflation tube 202.
Through the inflation tube 202 and the inflation bag 201 are communicated, the inflation bag 201 can be inflated and deflated through the inflation tube 202, different gas quantities are respectively injected into the inflation bag 201 through the inflation tube 202, so that the inflation bag 201 is in contact with the inner wall of the asymmetric laryngeal cavity, and the inflation bag 201 is in sealed fit with the inner wall of the laryngeal cavity of the patient.
In one embodiment of the present invention, as shown in fig. 1, the number of the air bags 201 is two, and two air bags 201 are symmetrically disposed about the ventilation assembly 100.
Through with the quantity of gas cell 201 sets up to two, and with two gas cell 201 sets up about ventilation assembly 100 symmetry, realizes two that the symmetry set up gas cell 201 can contact with the patient's larynx intracavity wall of symmetry, is convenient for adjust two that the symmetry set up simultaneously gas cell 201 gas injection volume, so that gas cell 201 can laminate sealedly to asymmetric patient's larynx intracavity wall.
As shown in fig. 1, the ventilation assembly 100 includes a ventilation mask 101 and a conduit 102, and one end of the conduit 102 is connected to the inside of the ventilation mask 101.
By communicating the conduit 102 with the mask 101, external air can be communicated with the laryngeal cavity space of the patient through the conduit 102 and the mask 101 when the device establishes an airway of the patient.
As shown in fig. 1, the inflatable bags 201 are wrapped around the edge of the ventilation hood 101, and a plurality of the inflatable bags 201 are connected end to end in sequence.
Through the gasbag 201 is right the edge of the ventilation mask 101 surrounds the cladding, make the gasbag 201 can effectively right the edge of the ventilation mask 101 shelters from, avoids the contact of the ventilation mask 101 and the inner wall of the patient's laryngeal cavity, leads to the reduction of the sealing effect of the device.
As shown in fig. 1, the balloon 201 is wrapped around the connection portion between the ventilation mask 101 and the catheter 102.
By coating the inflatable bag 201 on the connecting part of the ventilation hood 101 and the catheter 102, the inflatable bag 201 can effectively shield the connecting part of the ventilation hood 101 and the catheter 102, so that the connecting part of the ventilation hood 101 and the catheter 102 is prevented from being exposed, the connecting part of the ventilation hood 101 and the catheter 102 is reinforced, and the sealing effect of the device is further improved.
As shown in fig. 1, a plurality of the airbags 201 arranged around the airbag are in the shape of drops, wherein the tips of the airbags 201 in the shape of drops face to the side facing away from the vent assembly 100.
Through a plurality of arranging around the state that the gas cell 201 formed is injectd, guarantees after the gas cell 201 pours into the air and expandes, the tip of drop form can effectively carry out the butt location to sphincter on the esophagus of patient to make the whole inside fixed at patient's larynx cavity of device, wherein the curved avris of gas cell 201 can be convenient for gas cell 201 and the contact of patient's larynx cavity inner wall reduce simultaneously behind the gas cell 201 butt patient's larynx cavity inner wall, cause the discomfort to the patient.
As shown in fig. 1, an inflation installation part 2011 is installed on the inflatable bag 201, and the inflation pipe 202 is installed on the inflation installation part 2011.
Specifically, as shown in fig. 1, the inflation tube 202 is embedded in the inflation mounting portion 2011.
More specifically, as shown in fig. 1, the inflation installation portion 2011 is a tube extending along the length direction of the catheter 102 to the outside of the inflation bag 201, and the inflation installation portion 2011 and the inflation bag 201 are integrally formed.
Through with the tubulose the mounting means of inflating installation department 2011 restricts, reduces inflate installation department 2011 and patient throat wall contact, simultaneously integrated into one piece inflate installation department 2011 with the stability of device overall structure has been guaranteed to gas cell 201.
The working principle is as follows: when the device is used, the tail ends of the inflatable tubes 202 are connected through external inflation equipment, the device is placed in the space of the laryngeal cavity of a patient, the external inflation equipment is further used for injecting gas into the inflatable bags 201 through the inflatable tubes 202 to achieve expansion of the inflatable bags 201, and the inflatable bags 201 are further bonded and sealed to the laryngeal wall, wherein the external inflation equipment and the inflatable bags 201 are used for inflation in the prior art, and detailed description is omitted here.
When the space of the laryngeal cavity of the patient is asymmetric, the air injection amount inside the two inflatable bags 201 is adjusted, the inflatable bags 201 seal the inner space of the asymmetric laryngeal cavity, the sealing of the inflatable bags 201 to the laryngeal part of the pharynx is ensured, the use stability of the device is improved, and meanwhile, the probability of laryngeal complications caused by the fact that the laryngeal cavity of the narrow side is extruded by the inflatable bags 201 is reduced.
In summary, by surrounding the air bag 201 around the ventilation assembly 100, when the ventilation assembly 100 is placed inside the laryngeal cavity of the patient, the air bag 201 can seal and obstruct the gap between the ventilation assembly 100 and the laryngeal wall, so that the air above and below the laryngeal tube can enter and exit through the ventilation assembly 100, and meanwhile, the air bag 201 inflated independently can extrude the asymmetric laryngeal wall respectively, so that the decrease in the fitting degree between the air bag 201 and the laryngeal tissue when the laryngeal cavity space of the patient is asymmetric is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
