Background technology:
In the clinical medicine, tracheal intubation is a common technology.In the prior art, the axis of tracheal intubation process mouth, pharynx, larynx is difficult to approaching, influences therapeutic effect.Therefore, need utilize the harder intubate of quality to lead core and endotracheal tube is moulded " L " type or fish hook shape, be beneficial to endotracheal tube and enter trachea by glottis, after endotracheal tube tip is by glottis, pull out again and lead core along physiological bending.But, in the tracheal intubation process of per nasal, endotracheal tube need be through the nostril, nasal vestibule, cavum nasi proprium, choana, nasopharynx part, enters trachea by glottis again, all has physiological bending between nasal vestibule and nasal cavity, nasal cavity and the nasopharynx part, and nasal cavity and nasopharynx part softness, rich blood vessel, endotracheal tube are very easily damaged mucosa when the physiological bending and are caused hemorrhagely, even endotracheal tube is directly worn out mucosa, cause even more serious complication, cause doctor-patient dispute.
Summary of the invention:
The purpose of this utility model is to provide a kind of guiding device that is used for tracheal intubation, and the described this guiding device that is used for tracheal intubation will solve the technical problem that causes suffering, damages easily mucosa in the prior art endotracheal tube intubate process.
This guiding device that is used for tracheal intubation of the present utility model fixedly leads core by one and a sliding core guiding constitutes, describedly fixedly lead core and sliding core guiding is made of the wire elastic component respectively, wherein, described front end of fixedly leading core is fixedlyed connected with the front end of sliding core guiding, fixedly lead on the front end connecting portion of core and sliding core guiding and be arranged with a front-end block, fixedly lead and be arranged with one first slide block and one second slide block on the core, be provided with one first through hole on described first slide block and second slide block, sliding core guiding passes the described through hole on first slide block and second slide block, the tail end of fixedly leading core is set with a tail end piece, be provided with one second through hole in the described tail end piece, a sidewall in described second through hole is provided with an elasticity latch, sliding core guiding passes described second through hole, the rear portion of sliding core guiding is set with the location latch, and described location latch matches with second through hole and described elasticity latch.
Further, the tail end of described sliding core guiding is provided with block or handle.
Further, described front-end block is provided with a plurality of oblique groove stricture of vaginas.
Operation principle of the present utility model is: will fixedly lead core, sliding core guiding and front-end block and insert in the endotracheal tube, front-end block is apart from the front opening 1.5cm of endotracheal tube, the operator grips with forefinger and middle finger and leads core, handle or block with thumb press sliding core guiding tail end, fixedly lead the deformation that bends of core and sliding core guiding, utilize the front end of fixedly leading core and sliding core guiding adjustment endotracheal tube to proper angle, then, utilize location latch and elasticity latch locking sliding core guiding, carry out tracheal intubation at last.The position that in the intubate process, can need key to adjust a latch and elasticity latch according to angle.Regulate the position of fixedly leading two coasters on the core and can adjust the curved shape of fixedly leading core, thereby regulate the frictional force of fixedly leading between core and the endotracheal tube inwall.After finishing intubate, unclamp location latch and elasticity latch, endotracheal tube slips into glottis smoothly and finishes intubate.
This utility model and prior art compare, and its effect is actively with tangible.This utility model utilizes one fixedly to lead the insertion angle that core and sliding core guiding are adjusted endotracheal tube, utilization is fixedly led being slidingly connected and locking latch between core and the sliding core guiding and is regulated the curved shape of fixedly leading core and sliding core guiding, in the intubate process, can adjust the angle of conduit at any time, can be fast, carry out tracheal intubation under the situation of safety, damage minimum, reduce patient's misery and the anoxia time.
