A kind of visual device of inserting and inserting the back inspection of laryngeal mask of realizing

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of visual device of inserting and inserting the back inspection of laryngeal mask of realizing.

Background technology

Aspect the diagnosis and treatment of disease, 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.Laryngeal mask is topmost a kind of in the instrument of airway management.At present; Laryngeal mask implantation traditional method is to adopt blind spy mode; Laryngeal mask is inserted patient throat from the oral cavity; All to be the operator with naked eyes and experience judge this whole process accomplishes, thus laryngeal mask put in place situation, insert process whether unfavorable conditions such as turnover take place, insert the back obturation effect in addition and whether have reflux erroneous aspiration risk etc. all can only lean on operator's experience to judge.Therefore laryngeal mask 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.

Wherein: the first, video laryngoscope is a utilization optics and electronic imaging technology, amplified expose the regional visual field of larynx glottis; And under the guiding that carries the display device real time video image; Implement endotracheal intubation, this method often can't be used the patient of difficulty in opening mouth, though and seen glottis in the use; But, also need by the plastotype instrument because human body throat physiological bending makes tracheal intubation directly to insert;

The second, 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;

The 3rd, 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.

Above-mentioned technology all is to be used with tracheal intubation, is difficult to use aspect inserting at laryngeal mask.

The utility model content

The purpose of this utility model is the deficiency that overcomes prior art; A kind of visual device of inserting and inserting the back inspection of laryngeal mask of realizing is provided; The operator is when using this device to implement the laryngeal mask implantation; Can laryngeal mask be put in place accurately through the real time imaging pilot operationp of display on the device, and can effectively prevent to insert unfavorable condition such as process generation turnover; In addition, after laryngeal mask is inserted, can also use the inspection of this device to insert the obturation effect of back laryngeal mask and whether reflux erroneous aspiration risk etc. is arranged, safe and reliable.

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

The described a kind of visual device of inserting and inserting the back inspection of laryngeal mask of realizing of this utility model; Comprise tube core, be connected the operating grip of tube core rear end; Said tube core is connected with the laryngeal mask airway conduit is detachable; 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 a bending; This bending is matched with human body throat physiological bending degree, and perhaps tube core can carry out plastotype according to human body throat physiological bending degree by the operator, makes tube core smoothly laryngeal mask to be inserted patient throat from the oral cavity.

As the further improvement of above-mentioned technology, said optical lens and video sensor chip are installed in the tube core head, when tube core is positioned at laryngeal mask airway conduit and laryngeal mask air bag seam with optical lens after the laryngeal mask airway conduit is connected and video sensor chip.

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

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.

In this utility model, the inner optical lens of said tube core head is the camera lens that carries out antifog design.

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

(1) this utility model is through camera lens and video sensor chip (like CCD, CMOS or NMOS etc.); Convert optical imagery to digital signal; After handling through the Digital Video Processing chip again; Can realize real-time display video signal, laryngeal mask is accurately put in place, effectively prevent to insert process unfavorable conditions such as turnover take place; In addition, because tube core has certain rigidity, also play the effect that helps the laryngeal mask plastotype, the operator can implement the laryngeal mask implantation very easily through gripping the handle of this device, can observe the whole process of inserting through display.

(2) after this utility model cooperates laryngeal mask to insert; Insert the back effect if observe; Like obturation effect and whether reflux erroneous aspiration risk etc. is arranged; Can tube core be inserted laryngeal mask again through the airway tube of laryngeal mask, optical lens on the tube core and video sensor chip are positioned at laryngeal mask airway conduit and laryngeal mask air bag seam, thereby accomplish clearly to observe laryngeal mask air bag situation; The video sensor chip is positioned at laryngeal mask airway conduit and laryngeal mask air bag seam, just can gather the real time imaging of laryngeal mask balloon positions.

(3) through connector display 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 laryngeal mask are detachable connected modes, and the two is separable, easy accessibility, and can abandon after the laryngeal mask use, sanitation and hygiene can effectively prevent cross infection.

(5) the antifog design of the described device camera lens of this utility model can effectively guarantee clear picture.
