Abstract

The utility model belongs to the technical field of medical instruments and particularly discloses a trachea cannula video laryngoscope. The laryngoscope comprises a tube core and an operating handle connected with the rear end of the tube core. When the tracheal intubation video laryngoscope is in use, a trachea cannula is sleeved outside the tube core, an optical lens and a video sensor chip are arranged at the front end part of the tube core, i.e. the head part of the tube core, and a display is connected onto the operating handle. When an operator rescues patients subjected to operative anesthesia and critical patients and implements trachea cannula implantation on other patients subjected to resuscitation, the larynx and the glottis can be clearly exposed by a video which is provided by the display on the trachea cannula video laryngoscope disclosed by the utility model, so that the intratracheal cannula implantation is carried out under the guide of a video image, no parallax error or blind zone exists in the whole process basically, the trachea cannula can be successfully implanted when the glottis is seen, and thus, the success rate, the efficiency and the safety of the operation are greatly improved.

Description

A kind of tracheal intubation video laryngoscope

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of tracheal intubation video laryngoscope.

Background technology

Airway management is the key link in clinical anesthesia and the emergency resuscitation, and how to set up respiration channel fast and accurately is the target that domestic and international medical profession is pursued always.Tracheal intubation is topmost a kind of in the instrument of airway management.The endotracheal intubation traditional method is that laryngoscope is inserted from the oral cavity; Arrive at the root of the tongue and epiglottis intersection along tongue body; Lift laryngoscope then and appear glottis; Down endotracheal tube is inserted trachea through glottis visual, the best glottis angle of spying on is that sight line and last incisor edge, glottis line overlap to form the tracheal intubation axis.All to be the operator with naked eyes and experience judge this whole process accomplishes; Therefore must receive the influence of factors such as parallax illusion, and, have many individual variations because human anatomic structure is complicated; Particularly run into have that last front tooth is long, micromandible, maxillary height arch upward narrow down, lower jaw space compliance reduces, neck is short and thick and the patient of situation such as obesity; It is not good that possible glottis appears, and sight line just can't normally be spied on glottis, the as easy as rolling off a log like this difficult intubation that causes.Therefore airway management visual becomes very important research direction.

Be accompanied by the development of the department of anaesthesiology, the visual apparatus of existing airway management has video laryngoscope, fibre optics laryngoscope, bronchofiberscope etc.Video laryngoscope is utilization optics and electronic imaging technology; Amplified expose the visual field in larynx glottis zone, and under the guiding that carries the display device real time video image, implement endotracheal intubation; But this method often can't be used the patient of difficulty in opening mouth; Though and seen glottis in the use because human body throat physiological bending makes tracheal intubation directly to insert, also need by the plastotype instrument.The fibre optics laryngoscope belongs to the optics sight glass, and existing does not have display device, can only use eyepiece to observe, camera lens haze easily cause misted.Bronchofiberscope is wider to the adaptive surface of difficult airway, but operating technology requires height, and price and maintenance cost are expensive, the problem that also exists camera lens to haze easily.

The utility model content

The purpose of this utility model is the deficiency that overcomes prior art; A kind of tracheal intubation video laryngoscope is provided; The operator is when rescuing surgery anesthesia, critical patient and other patients that implement resuscitations are implemented the tracheal intubation implantation; Can insert so that under the guiding of real time video image, carry out endotracheal intubation through clear larynx and the glottis of appearing of the video that display on the described tracheal intubation video laryngoscope of this utility model provides, make whole process no longer include the existence of parallax and blind area; Basically see that glottis just can successfully insert tracheal intubation, thereby improve success rate, efficient and the safety of operation greatly.

In order to reach above-mentioned technical purpose, this utility model is realized by following technical scheme:

The described a kind of tracheal intubation video laryngoscope of this utility model comprises tube core, is connected the operating grip of tube core rear end, and tracheal intubation is sheathed on outside the said tube core during use.The leading section of said tube core is provided with optical lens and video sensor chip, and said operating grip is provided with display.

Further improvement as above-mentioned technology; Said tube core is out of shape for the bending that cooperates with human body throat physiological bending degree or tube core can carry out plastotype by the operator according to human body throat physiological bending degree, makes tube core smoothly the laryngeal mask human mouth to be inserted patient throat.

In this utility model, said display is connected on the operating grip through connector is rotating, and said display can be undersized liquid crystal display.

As the further improvement of above-mentioned technology, when tracheal intubation was enclosed within the tube core periphery, said optical lens and video sensor chip were installed on and are positioned at tracheal intubation patient end opening part in the tube core head.

In this utility model, said video sensor chip is CCD electronic sensor chip, cmos sensor chip or NMOS sensor chip.

In addition, in this utility model, in order to solve the problem that optical lens hazes easily, said optical lens is the camera lens through antifog design.

Compared with prior art, the beneficial effect of this utility model is:

(1) in this utility model; Optical lens and video sensor chip are installed in the tube core head of laryngoscope front end; The tube core head carries out plastotype by human body throat physiological bending; After tracheal intubation was inserted in tube core, optical lens on the tube core and video sensor chip were positioned at tracheal intubation patient end opening and go out, and can gather patient throat glottis real time imaging;

(2) tube core has certain rigidity in this utility model, also plays the effect that helps the tracheal intubation plastotype, and the operator can implement the tracheal intubation implantation very easily through gripping the operating grip of this laryngoscope, can observe the whole process of inserting through display.

(3) through connector display (small-size liquid crystal displays) is movably connected on the operating grip with rotating connected mode in this utility model, the person observes video image with handled easily;

(4) described device of this utility model and tracheal intubation are detachable connected modes, and the two is separable, easy accessibility, and can abandon sanitation and hygiene after the tracheal intubation use.

(5) in this utility model, the optical lens that said tube core head is installed carries out antifog design, effectively solves the problem that optical lens is prone to haze, and guarantees that vision is clear.
