Passage 21 remote outlet 211 centerlines is 10 °-20 °, and the setting of photographic head 9 may determine that the in-position of endotracheal tube
The most correct, if just to glottis, before the head of photographic head 9 points to, upper, interior direction, field range is suitable for reading more than whole cover capsule,
And it can be seen that whole vocal area, the situation of laryngeal mask and glottis para-position can be monitored in real time, and when endotracheal tube inserts, vocal area
Being still within photographic head 9 within sweep of the eye, photographic head 9 can observe sidewall and the glottis position of endotracheal tube, thus
Improve the success rate of laryngeal mask para-position and through the success rate of laryngeal mask tracheal intubation, reduce damage and the risk of air flue；Cable 91
Device is in visual channel 22, and is connected with photographic head 9；Drainage channel 23 expert's stomach tube, drainage channel 23 port of export 231 is in tiltedly
Planar, in smoothing junction with conduit 2 remote outlet 26 back, as shown in Figures 4 and 5, the outlet of inclined plane shape makes laryngeal mask insert human body
When oral cavity, pharyngeal cavity more smooth, reduce damage to bottleneck throat mucosa.
As shown in Figure 6, joint 3 includes that anchor tip 31 and side wing type fixed handle 32, side wing type fixed handle 32 are fixed on
Determining joint 31 both sides one-body molded with anchor tip 31, to offer tube chamber 311 in anchor tip 31, tube chamber 311 arrival end is i.e.
Part on side wing type fixed handle 32 is circular, the exporting front portion down to tube chamber 311 and be divided into ellipse of side wing type fixed handle 32,
Its interior cavity entirety is increased, reduces aeration resistance, in interior tube chamber 311, general intubation catheter can be accommodated, because footpath is big around
In anteroposterior diameter, being significantly reduced and intubate resistance, the interior tube chamber of the remote outlet 211 of cannula passage 21 is the most rounded, it is simple to trachea
Intubate towards center line direction；Side wing type fixed handle 32 is fixed on corners of the mouth both sides, thus oppresses upper and lower mouth when avoiding the most fixing
Lip, side wing type fixed handle 32 be also laryngeal mask position be the most suitably to identify, as it is shown in fig. 7, the two of side wing type fixed handle 32
Side is respectively equipped with fixation hook 321, and side wing type fixed handle 32 is fixed at patient head, side wing type fixed handle 32 end by convenience belt
Portion is respectively equipped with and side wing type fixed handle 32 and the integrated boss of anchor tip 31 1 and boss 2 34, boss 1 and
The fixing stomach tube chamber 7 of drainage channel 23, boss 2 34 and the side of top thereof it is communicated with in side wing type fixed handle 32 above it
Offer in wing formula fixed handle 32 connect with visual channel 22 cavity 35, interface 8 can be embedded in cavity 35, this interface 8 with
On side wing type fixed handle 32, plane is concordant, and cable 91 enters cavity 35 and is connected with interface 8, display 10 inserting through connecting line 101
102 are connected on interface 8.Fixing stomach tube chamber 7 arrival end is provided with the adapter of 5-6mm length in side wing type fixed handle 32 plane
71, adapter 71 is connected with drainage channel 23 by fixing stomach tube chamber 7, and arranging of adapter 71 can be effectively prevented adhesive tape blocking admittedly
Determining stomach tube chamber 7, it is simple to assignment test, the angle between adapter 71 centrage and tube chamber 311 centrage is 30 °, setting of this angle
Put the insertion being easy to stomach tube, do not produce friction with anchor tip 31.
During Clinical practice this utility model, insert patient's esophagus upper end by most advanced and sophisticated for laryngeal mask through ccavum oropharygeum, run through inflation
Pipe 4 is inflated, and makes cover capsule 1 open by conduit 2, can be observed the situation of laryngeal mask and glottis the most incessantly by display 10,
Long-time use, is trapped in drain lacuna 25 owing to having juice inside air flue, at this moment can be inhaled by sputum aspirator tube
Go out, thus prevent internal inflammations and the generation by mistake inhaled, it is possible to insert endotracheal tube by conduit 2 and maintain ventilation, art can be led to
Cross stomach tube lock chamber 7 and insert stomach tube, drain gas and the liquid of gastric, thus avoid flatulence, and prevent liquid suction by mistake of backflowing
Enter air flue.
The beneficial effects of the utility model: 1. this utility model can pass through photographic head and the continuous continual prison of display
Survey the situation of laryngeal mask and glottis para-position, in order to make adjustment in time, reduce examination repeatedly and insert oral cavity, the bottleneck throat damage wind caused
The risk probability that danger, reduction airway obstruction and laryngeal mask are failed, improves laryngeal mask quality.2. need to insert gas through laryngeal mask
During pipe conduit, can complete under video surveillance, improve successful intubation, reduce the risk of Airway damage.3. need not
Additionally configure the visual device repeatedly utilized, it is to avoid the risk of cross infection.4. drain lacuna and bridge construction arrange existing
Being beneficial to absorb the secretions bottom laryngeal mask, more play the effect of epiglottis fence, when epiglottis cover outlet, drain lacuna plays anti-
The only effect of airflow obstruction.5. the setting of drainage channel make stomach tube can exactly, be rapidly introduced into esophagus stomach function regulating intracavity.6.
Simple in construction, low cost, easy to use, laryngeal mask can be made well to combine with endotracheal tube, stomach tube, visual device.
Obviously, above-mentioned embodiment of the present utility model is only for clearly demonstrating this utility model example,
And it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, state upper
Can also make other changes in different forms on the basis of bright.Here all of embodiment cannot be given thoroughly
Lift.Every belong to obvious change or variation that the technical solution of the utility model extended out still in this utility model
The row of protection domain.
