Visible trachea cannula hard lens for airway surface anesthesia

Abstract

The invention provides a visible trachea cannula hard lens for airway surface anesthesia. The visible trachea cannula hard lens is characterized by comprising a display, a hard lens handle, a high-pressure bottle and a stainless steel tube. The high-pressure bottle is arranged in the hard lens handle, and a camera shooting unit and a spray head are arranged at the front end of the stainless steeltube; the high-pressure bottle is filled with local anesthesia liquid medicine and high-pressure gas, a bottle valve is arranged at the bottom end of the high-pressure bottle, and the high-pressure bottle can be installed in a medicine bin of the hard lens handle; a local anesthesia liquid medicine conveying pipeline is arranged in the stainless steel tube, one end of the local anesthesia liquid medicine conveying pipeline is connected with the spray head, and the other end of the local anesthesia liquid medicine conveying pipeline is connected with the bottle valve through a tail pipe; and aspraying key is arranged at the front end of the hard lens handle, and the gas in the high-pressure bottle can be triggered by pressing the spraying key to push the local anesthesia liquid medicine tobe sprayed out through the spray head. The visible trachea cannula hard lens can perform surface anesthesia on any part in a visible range, enables an anesthesia effect to be accurate, reliable and controllable, is especially suitable for trachea cannula operation of difficult airway patients with poor head and neck mobility, head and neck trauma, small mouth opening degree, obesity, short neck,high glottis and the like, can be operated by a single person and is low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visual intubation rigid mirror for airway surface anesthesia. Background technique [0002] Endotracheal intubation is one of the airway management methods commonly used by anesthesiologists. There are many types of endotracheal intubation tools, but in clinical work, difficult airways (poor head and neck mobility, small mouth opening, and hyperglottis) are often encountered. height, maxillofacial trauma, tongue hypertrophy, etc.), which brings great difficulty for anesthesiologists to use ordinary tools for tracheal intubation, while the hard video mirror requires a small head-back angle and a small mouth opening. It is widely used in tracheal intubation of patients with difficult airway due to its advantages such as no need to lift the epiglottis to expose the glottis during tracheal intubation. However, even with many advantages of rigid visual mirrors, it is difficult to avo...

AI Technical Summary

Problems solved by technology

However, the device sprays by pressing and pressing the handle, which is cumbersome to operate; and the spray effect is affected by the force of the operator, and the spray effect is unstable; the device uses four U-shaped laryngoscope clips to fix it on the common laryngoscope. The fixing clip is not fastened tightly, and the position and angle of the nozzle are unstable; the fixing clip may fall off into the airway, which poses a risk to patient safety

And the device cannot be used for patients with difficult airway, which limits the application range of the device, so it is difficult to promote the use of the device in clinical practice
