Description
Technical field
This utility model belongs to medical instruments field, especially relates to a kind of laryngoscope.
Background technology
In present clinical medicine, the breathing that need to maintain patient when patient is implemented anesthesia or rescued is unimpeded, therefore tracheal intubation is the most basic treatment and first aid hands section, it is very crucial, because the structure of human body bottleneck throat is more complicated, often need to be by laryngoscope, this technology has obtained significant progress, traditional laryngoscope method is that laryngoscope blade is inserted until epiglottis from oral cavity along tongue body, then appear glottis with lifting epiglottis on laryngoscope blade, now medical personnel insert endotracheal tube again through glottis, this intubation technique is by naked-eye observation, sight line is subject to the restriction of tooth edge and bending respiratory tract, easily there is parallax and blind area, cause epiglottis to expose unclear, therefore this process need operator complete by rule of thumb, in addition due to the difference of individual patients, very easily cause the phenomenon of difficult intubation, and then delay rescue time, therefore endotracheal intubation becomes research staff's research topic.
Be accompanied by patient's needs and the development of technology, electric video laryngoscope technology has solved the defect of traditional laryngoscope method, the publication No. of for example being researched and developed by Japan is the problem that technology that CN102481429A, patent name are laryngoscope has well solved intubate difficulty, the image that display part is taken image pickup part shows in real time, therefore more easily directly perceived to the intubate operation of patient's enforcement.
But due to the natural torsion of human body throat respiratory tract existence and the complexity of glottis place structure, and intubate used be soft tube, even if there is the picture of real-time demonstration, endotracheal tube still can not be aimed at very accurately glottis and insert, and also can cause damage to oral cavity wall because conduit is arbitrarily mobile in oral cavity, so research staff redesigns laryngoscope blade for this problem, a kind of New larynx lens that for example publication No. is CN102580217A has solved current difficulty, it is designed to be provided with approximate " U " type and not exclusively seal in a side of laryngoscope blade main body the elasticity tracheal intubation guide groove of tract, while applying this design, endotracheal tube is inserted to person's windpipe by elasticity tracheal intubation guide groove, but this patent has certain problem:
1). because this guide groove and laryngoscope body are not one-body molded, it has adopted, and groove connects, the mode of bonding, pin joint or link, and therefore structure is more complicated, and cost of manufacture is larger simultaneously.
2). while carrying out intubate, glottis center is the optimum position of intubate, in intubate process, fully expose epiglottis and glottis extremely important, be directly connected to intubate success, therefore medical domain is general all by just right to the center in the photographic head visual field and glottis, although the gathering sill of this laryngoscope blade has played guide effect to endotracheal tube, but this guide groove direction and shooting pipeline parallel (seeing Figure of description), if therefore the center in the photographic head visual field and glottis are just right, that endotracheal tube just enters a side of the trachea tract by patient, is unfavorable for like this intubate.
Utility model content
Problem to be solved in the utility model is to provide a kind of laryngoscope blade of easy operating simple in structure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of disposable laryngoscope blade with intubate guidance type draw-in groove, comprise laryngoscope blade main body and spatula, all curved and concave surface is all upwards for this laryngoscope blade main body and spatula, described spatula is arranged at the top of laryngoscope blade main body, described spatula at the viewfinder end of laryngoscope blade main body along its camber direction formation elongated end that stretches out, this disposable laryngoscope blade also comprises base plate, described base plate is positioned at the bottom of laryngoscope blade main body one side, described base plate is arc and concave upright, described base plate at the viewfinder end of laryngoscope blade main body along its camber direction formation guide plate that stretches out, described elongated end is greater than the distance of guide plate outer end apart from viewfinder apart from the distance of viewfinder, described base plate is provided with baffle plate in a side relative with laryngoscope blade main body, the side of described laryngoscope blade main body, spatula, base plate and baffle plate form intubate guidance type draw-in groove, the width of described intubate guidance type draw-in groove and height are reduced gradually by entrance to its outlet of this intubate guidance type draw-in groove, the port of export of described intubate guidance type draw-in groove is provided with guider, described laryngoscope blade main body, spatula, base plate and baffle plate are one-body molded.
Further, described guide plate outer end is 812mm apart from the distance of the viewfinder of laryngoscope blade main body.
Further, the radius of curvature of the arcwall face of described base plate is 72～82mm.
Further, described guider comprises localizer, and described localizer and baffle plate are one-body molded, and this localizer is curved towards viewfinder direction.
Further, described guider also comprises and pushes guiding root, described propelling movement guiding root between the centrage and laryngoscope blade main body of base plate guide plate, and this propelling movement lead root and base plate one-body molded.
Further, described spatula is provided with briquetting in the upper surface level of elongated end, and described briquetting and spatula are one-body molded, and described briquetting is cylindrical.
