Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
Fig. 1 is the structural representation of the oropharyngeal airway of the present embodiment.
Fig. 2 is the side view of the oropharyngeal airway of the present embodiment.
Fig. 3 is the structural representation in the A-A cross section in Fig. 1.
As shown in FIG. 1 to 3, oropharyngeal airway 100 comprises the oropharyngeal airway body be made up of the joint face 3 of top-surface camber 1, lower surface camber 2 and connection two curved surfaces, be positioned at the video portion 6 on joint face 3 top, the power supply 7 of powering for video portion 6 and be positioned at external, for the display part of display video portion 6 image.
In oropharyngeal airway body, top-surface camber 1 comprises along the first top-surface camber 11 and the second top-surface camber 12 in seesaw-type of joint face 3, first top-surface camber 11 and the lower surface camber 21 corresponding to it form first passage 4, second top-surface camber 12 and the lower surface camber 22 corresponding to it form second channel 5, and first passage 4 or second channel 5 are both for improving ventilation also for guiding endotracheal tube to insert.Joint face 3 is with multiple aperture 31, and for when side channel blockage, gas can enter an other wing passage through small holes 31, meet ventilation requirement, the cross section of first passage 4 and second channel 5 is C font, and object is in order in catheterization procedure, prevents endotracheal tube from departing from passage.
The profile of oropharyngeal airway 100 is similar with oropharyngeal airway of the prior art, also with oral cavity and pharyngeal mating shapes, also the edge of a wing 10, bite-block bite 20 and pharynx bending section 30 is divided into, the knee of top-surface camber 1 is little lateral bending, coincide with back radian, the knee of lower surface camber 2 is large lateral bending, with soft, hard palate and swallow rear wall and be affixed.
In order to prevent in whole operating process, the unartificial initiative activity of top-surface camber 1, on the edge of a wing 10, place arranges support 8, and support 8 comprises the first support 81 and the second support 82 being arranged at first passage 4 and second channel 5 edge of a wing place respectively.First support 81 is identical with the second support 82 structure, and all in hook-shaped, support one end and lower surface camber are rotationally connected, another end hook on the edge of a wing of top-surface camber, for fixing the first top-surface camber and the second top-surface camber.
Fig. 4 is the structural representation in the video portion in the present embodiment.
As shown in Figure 1 and Figure 4, in the form of a ring, centre is image unit 61 in video portion 6, is a plurality of luminous bodys 62 around image unit 61.Power supply 7 is button cell, and be positioned at lower surface camber 2 one end away from video portion 6, power supply 7 is connected with video portion 6 by wire, for image unit 61 and luminous body 62 are powered.Wire is very thin, by being arranged on recessed bond ing battery in joint face 3 and video portion 6.
Be support 8 to the control assembly of 6 on-off actions in video portion, when having and only have the first support 81 and the second support 82 all to depart from top-surface camber, image unit 61 and luminous body 62 are just de-energized.
In the present embodiment, image unit is micro radio photographic head, and luminous body is LED bulb, the display screen of wireless signal of display part for receiving micro radio photographic head and send.Display location, in external, adopts other power supply for its power supply, the wireless signal about glottis structure sent by the wireless signal receiver reception micro radio photographic head of inside.
In the present embodiment, the connected mode of the first top-surface camber and the second top-surface camber is similar to hinge.The upper end of joint face is widened, both sides, upper end are projection slightly, and arrange one and to be connected with two lateral processes and the identical axle of joint face upper end shape, outer shaft sleeve has sleeve pipe, first top-surface camber and the second top-surface camber are horizontally placed on the two ends of sleeve pipe respectively, when pressing pressure side top-surface camber, rotation of sleeve, drives opposite side top-surface camber to tilt.In the present embodiment, do not need the tilting degree of curved surface very large, as long as slightly tilt, make passage easily depart from endotracheal tube, therefore the inner surface of sleeve pipe directly can contact with the outer surface of axle, as long as keep smooth surface.
Under insert with endotracheal tube the using method that oropharyngeal airway in the present embodiment is described along first passage 4: first, oropharyngeal airway is inserted, now two side stands are all in the state of closing, and according to the image in display screen, judge that whether the position that oropharyngeal airway is placed is correct; Secondly, after mask ventilation terminates, when carrying out endotracheal tube intubate, open the first support 81, now the second support 82 is still in the state of closing, and video portion 6 is in "on" position, under visual condition, insert endotracheal tube; Finally, endotracheal tube inserts successfully, second support 82 is opened, power supply disconnects, press pressure second top-surface camber 12, first top-surface camber 11 is tilted, and moved to the second top-surface camber 12 side by oropharyngeal airway, oropharyngeal airway is withdrawn from while departing from from first passage 4 by endotracheal tube from oral cavity.
The effect of embodiment and effect
Present embodiments provide a kind of oropharyngeal airway, comprise by top-surface camber, the oropharyngeal airway body of lower surface camber and joint face composition and the video portion for glottis structure observed in vitro, display part and power supply, top-surface camber in oropharyngeal airway body comprises with the first top-surface camber of seesaw-type connection and the second top-surface camber, press one of them curved surface of pressure, namely opposite side curved surface can tilt, cause channel height adjustable, the oropharyngeal airway that the present embodiment is provided is while improvement ventilation, the guiding channel that also can insert as endotracheal tube, both the problem of mask ventilation difficulty had been solved, additionally reduce and exit common oropharyngeal airway, re-use the time spent by laryngoscope intubation, namely the hypoxic exposure of patient when induction tracheal conduit inserts is reduced, and reduce laryngoscope in operation, patient oral cavity is brought to the risk of damage.
In addition, the channel cross-section of the oropharyngeal airway that the present embodiment provides is C font, effectively prevent the phenomenon guiding endotracheal tube in endotracheal tube insertion process to depart from passage to occur, simultaneously, support is not only as the switch in video portion, also serve the effect of fixing top-surface camber, avoid the unartificial initiative activity of top-surface camber, improve the insertion efficiency of endotracheal tube.
This utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined in described claim; these changes are apparent, and all innovation and creation utilizing this utility model to conceive are all at the row of protection.
