Meanwhile, the drainage channel is arranged to extract the gastric contents, so as to prevent backflow and aspiration.
In this embodiment, the visual laryngeal mask further includes a drainage tube 8, a drainage hole 81 communicated with the drainage tube 8 is formed at the distal end of the bowl body 21, and the second camera module 6 is arranged near the drainage hole 81, so that the reflux condition of stomach liquid can be known in time through the second camera module at the distal end, gastric contents can be extracted in time, and reflux aspiration can be prevented, in this embodiment, the second camera module 6 is arranged at the upper end of the drainage hole 81;
in some embodiments, the first camera module 5 and the second camera module 6 are wirelessly connected to the display 7, and can be wirelessly connected to the display 7, such as a display screen, through a wireless communication, such as bluetooth, so that the display 7 can display an image of the patient, and at this time, the first camera module 5 and the second camera module 6 are directly and directly fixed to the ventral surface or the distal end of the bowl body 21, and such an assembly enables the first camera module 5 and the second camera module 6 to be integrated with the bowl body 21 itself, which is too costly as a disposable product; furthermore, the visual device is not needed by all patients, but is used in a situation where the laryngeal mask itself is not inserted well, in which case every patient must force the device to be used, and it is unnecessary, resulting in waste of resources.
In other embodiments, the first camera module 5, the second camera module 6 and the display 7 are electrically connected to a second connecting wire (not shown) through a first connecting wire 55, that is, the first camera module 5, the second camera module 6 and the display 7 are connected by wires, and in this case, the camera module and the connecting wire may be embedded in the visual laryngeal mask or may be detachably arranged; when it is embedded in the ventilation pipe 1, it is integrated with the bowl body 2 itself, which is too costly as a disposable product; furthermore, the visual device is not needed by all patients, but is used in a situation where the laryngeal mask itself is not inserted well, in which case every patient must force the device to be used, and it is unnecessary, resulting in waste of resources.
Based on this, the present embodiment is improved by that the visual laryngeal mask includes a first visual channel 9 and a second visual channel 10, the first visual channel 9 extends from the proximal end of the ventilation tube to the ventral surface 21c of the bowl body, the second visual channel 10 extends from the proximal end 1a of the ventilation tube to the distal end 21b of the bowl body, and the distal ends of the first visual channel 9 and the second visual channel 10 respectively have a first observation window and a second observation window; the first connecting line 55 passes through the first visual channel 9 to send the first camera module 5 to the first observation window, and the second connecting line passes through the second visual channel to send the second camera module to the second observation window, so that the first camera module 5 and the second camera module 6 can obtain images; specifically, the first camera shooting assembly 5 and the second camera shooting assembly 6 are respectively matched with the first visual channel 9 and the second visual channel 10 in a pluggable manner through the belt guides of the first connecting wire and the second connecting wire, so that the connecting wires can be used as the electric connecting pieces and also used as the guide pieces to guide the first camera shooting assembly and the second camera shooting assembly to be pulled out of the visual channels, and the visual device can be used only when the visual device is needed;
regarding the structure of the first observation window and the second observation window, the distal ends of the first visual channel and the second visual channel form an opening, and the opening forms the first observation window and the second observation window for the first camera shooting assembly and the second camera shooting assembly to obtain images in the body of a patient, however, as the visual laryngeal mask is generally a disposable medical instrument, if the distal ends of the first visual channel and the second visual channel form an opening, the camera shooting assembly is polluted, the disinfection cost is high, and if the visual laryngeal mask is used as a disposable product, the treatment cost of the patient is higher, and the visual laryngeal mask is not environment-friendly; therefore, in the present embodiment, the distal ends of the first visual channel and the second visual channel are provided with closed transparent covers to respectively form a sealed first viewing window and a sealed second viewing window; thus, the transparent cover at the far end can play an imaging effect while sealing the camera part from being polluted by body fluid of a polluted patient due to the transparent characteristic of the transparent cover.
The first visual channel 9 and the second visual channel 10 are distributed on the left side and the right side of the ventilation pipe, so that the operation of a doctor in an operation is facilitated.
In this embodiment, the transparent cover at the distal end is generally cylindrical, and the front end is in a circular arc transition.
It can be understood that the first visual channel and the second visual channel are independently arranged from the ventilation cavity, so that the first camera shooting assembly and the second camera shooting assembly can be effectively prevented from being polluted;
in some embodiments, the visual laryngeal mask includes a first cleaning channel 110 that extends from a proximal end of the ventilation tube to a ventral surface of the bowl body and a distal end of which forms a cleaning aperture towards the first viewing window; more preferably, the visual laryngeal mask includes a second cleaning passage that extends from the proximal end of the ventilation tube to the distal end of the bowl body and the distal end of which forms a cleaning aperture towards the second viewing window;
the effect of first clean passageway and the clean passageway of second all is in time washs the pollutant on the subassembly of making a video recording, avoids it to shelter from the formation of image field of vision, causes the linearity that no visual effect or visual effect weaken.
Specifically, the outer side of the laryngeal mask is respectively provided with a joint 111 connected with the first cleaning channel and the second cleaning channel so as to be connected with an infusion tube and the like, so that the supply of cleaning fluid is facilitated.
Specifically, the spring is a stainless steel wire spring, and the spring spirally encircles from the near end to the far end of the tube wall of the vent tube to play a bending function.
It will be appreciated that, as a preferred electronic mirror, the first and second camera assemblies include at least a camera 51 and an LED light source 52.
In the embodiment, the flexible vent pipe extends linearly, and the hardness of the flexible vent pipe is between 0 and 60 shore A for convenience of operation; preferably the shoreA 30-40.
In this embodiment, the balloon is an inflatable balloon, which can be inflated by an inflation tube 220, and the inflation degree can be adjusted according to the size of the throat of the patient.
