Description
Technical field
Degree laryngoscope blade is continuously moved the present invention relates to medical instruments field, more particularly to a kind of integrated flexible.
Background technology
Because throat position is deeper, physiological structure is complicated, it is impossible to directly peep and, when medically checking throat often
Need by laryngoscope.Current laryngoscope blade has the following disadvantages：1. the laryngoscope blade beaming limit angle of different series is different and has
Limit, therefore generally require to be used alternatingly between the laryngoscope blade of different series during actual use；2. laryngoscope blade angle plastotype is fixed, even if
Still need the collocation of multi-angle model eyeglass standby with a series of laryngoscopes；3. laryngoscope blade, can not because material is hard, angle is fixed
Having when inserting, adjusting laryngoscope blade position and proposing mirror operation with avoiding causes tooth and soft tissue injury may；4. larynx
Eyeglass is expensive, will not be used under normal circumstances as medical disposable material, this just bring sterilization, health in terms of ask
Topic.
The content of the invention
It is not enough for more than, it can solve the problem that single laryngoscope blade front end angle of bend has it is an object of the invention to provide one kind
Limit, integrated flexible the problems such as material is really up to the mark, use cost is high continuously move degree laryngoscope blade.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
Integrated flexible continuously moves degree laryngoscope blade, including：
