Now along with development of science and technology, novel electron video laryngoscope The Application of Technology particularly efficiently solves the defective of traditional direct laryngoscope method.The operation of tracheal intubation is more prone to; Whole intubate process is no longer because the existence of parallax and blind area, and the generation that firmly causes complication such as loss of tooth, the root of the tongue are pulled, hemorrhage and vocal cords edema because of rough occurs.Visual intubate process makes the more traditional direct laryngoscope method of its whole operation process more accurately, intuitively and easily.
It is easy that yet existing video laryngoscope mostly exists a problem to be that glottis exposes in video technique, but provoke insufficiently owing to epiglottis, adds the natural torsion of human body throat respiratory tract to cause tracheal intubation can't get into glottis on the contrary.Carry out mouldingly so often will be in advance be inserted in moulding to tracheal intubation, could successfully implement endotracheal intubation, this has just increased the complexity and the cost of operation.
Also there is producer to notice this problem now, on the laryngoscope blade that inserts throat, increased the tracheal intubation guide groove, help the tracheal intubation plastotype, with the convenient endotracheal intubation of successfully implementing through guide groove.Tracheal intubation is to divide model according to outside dimension, and the doctor can select the tracheal intubation of different model according to factors such as age of patient, sex, body weight when selecting tracheal intubation, could set up respiration channel for patient better like this.But because these laryngoscope blade guide grooves all are plasticity; Tracheal intubation for different model can't be well compatible; The tracheal intubation that external diameter is big can not get into guide groove; The little tracheal intubation of external diameter gets into behind the guide groove again too pine, and the big tracheal intubation of external diameter is difficult for from this guide groove, separating, and this brings inconvenience to implementing endotracheal intubation.
Summary of the invention

For reaching above-mentioned technical purpose, the present invention realizes through following technical scheme:
A kind of laryngoscope blade of the present invention; Comprise laryngoscope blade main body and spatula; Spatula is positioned at the top of laryngoscope blade main body and extends to front end, and is in aggregates with the laryngoscope blade main body, a side of said laryngoscope blade main body be provided with one have an incomplete sealing tract elasticity tracheal intubation guide groove.Said tracheal intubation guide groove is for upwarping shape, and its cross section is approximate " U " type.
As the further improvement of above-mentioned technology, said tracheal intubation guide groove patient end has a convexity, is calibration portion, and said tracheal intubation guide groove patient end axial outer edge tangent line and calibration portion inward flange tangential direction are 0-80 ° of angle.
As the further improvement of above-mentioned technology, said tracheal intubation guide groove is the stagewise guide groove, can be divided into independent two sections or more than two sections.
Tracheal intubation guide groove of the present invention and laryngoscope blade main body through groove connect, bonding, pin joint or the mode that links be connected.
Compared with prior art, beneficial effect of the present invention:
The present invention structurally provides elasticity tracheal intubation guide groove; So that carry out resilient engagement with the tracheal intubation of different model, the handled easily person implements tracheal intubation, in addition; After the tracheal intubation success, because the elasticity of guide groove makes that tracheal intubation is easy to separate with laryngoscope blade from the guide groove upper opening.Tracheal intubation guide groove patient end is and upwarps shape, makes trachea more can get into glottis exactly.Further, the tracheal intubation guide groove can adopt stagewise, and the frictional resistance face that reduces tracheal intubation and guide groove also reduces the cleaning-sterilizing difficulty simultaneously.
