Description

Anesthetic laryngoscope

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to anesthetic laryngoscope.

Background

In the anesthesia field, need carry out the intubate to disease trachea under the many cases and diagnose, at this moment need carry out necessary anesthesia to the disease and handle, generally need insert the disease oral cavity with the laryngoscope earlier this moment, then gradually stretch into the throat position of disease, the trachea of other means to disease throat position of rethread this moment anaesthetizes the operation, and this process is comparatively complicated, has increased medical personnel's intensity of labour, and it is long, work efficiency is low to diagnose the process consuming time.

In order to improve the prior art, long-term research has been conducted and various solutions have been proposed. For example, chinese patent literature discloses an anesthetic laryngoscope [ application No.: CN201820325812.7], including the laryngoscope lens, still include first handle subassembly, the second handle subassembly, the anesthetic spouts the bottle, the spray tube, the anesthetic spouts the bottle dress and locates in the first handle subassembly, the first handle subassembly has first end, the one end and the first end fixed connection of laryngoscope lens, the exit end of anesthetic spouts the bottle towards first end, second handle subassembly one end is connected with the bottle exit end that the anesthetic spouts the bottle, spray tube one end link up with the bottle exit end that the anesthetic spouts the bottle, the other end of spray tube is located on the laryngoscope piece, the second handle subassembly still articulates with first handle subassembly, when first handle subassembly and second handle subassembly produce relative motion around articulated position, so that the narcotic can reach the throat position via the spray tube.

Although the scheme solves the defects of the prior art to a certain extent, the position of the laryngoscope lens is fixed, the angle can not be adjusted according to the age or individual difference of patients, in addition, when patients who have neck anatomical variation, cervical spondylosis, high neck strength, small jaw, too high glottis and can not normally stretch and bend the neck are encountered, the glottis of the throat can not be seen, so the problem that the throat is difficult to be peered by the anesthesia cannula can occur when the anesthesia cannula is performed, the tracheal cannula can only be performed blindly, side injury can be caused sometimes, the smooth success of the tracheal cannula can not be ensured, anesthesia accidents can be caused seriously, and meanwhile, according to the design, when the residual anesthetic dosage in the medicine spraying tube is small, the anesthetic can not be sprayed well to influence the anesthesia effect, and treatment is delayed.
