Abstract

The utility model relates to a removable type electronic video anesthetic laryngoscope. The laryngoscope is connected with a handle through a clasp, the electrical connectors of the laryngoscope and the handle which are clipped are switched-on through conductive contacts, an illuminating lamp and an image sensor camera are respectively arranged at the front end of the laryngoscope, a liquid crystal display is arranged at the rear end of the handle and movably connected with the handle, and the liquid crystal display and the handle can be mutually rotated and pitched. The utility model has the advantages that the electronic video anesthetic laryngoscope and the handle can be disassembled to be convenient for clinical disinfection; the image sensor and the image signal processing circuit are installed in the laryngoscope shell, thereby the electric connection of the sensor is simplified, the sensor is connected with the handle only through three conductive contacts, thereby the electronic video anesthetic laryngoscope and the handle can be disassembled; since the liquid crystal display is movably connected with the handle, and the liquid crystal display can be changed at an angle horizontally and longitudinally, thereby the observation during the operation is convenient; and the external display is connected through a video signal output terminal, thereby facilitating the medical teaching.

Description

Dismountable electric video anesthetic laryngopharyngoscope

Technical field

This utility model is used for the anesthetic laryngopharyngoscope of tracheal intubation, particularly a kind of dismountable electric video anesthetic laryngopharyngoscope with liquid crystal display when relating to a kind of clinical anesthesia and rescue.

Background technology

At present, the general anesthesia laryngopharyngeal mirror of usefulness generally all is not to be with display clinically, and the doctor carries out the tracheal intubation operation with sensation and experience simultaneously, but often runs into owing to can't directly see glottis clearly by the laryngopharyngeal mirror direct observation, causes difficult intubation or failure.Image sensor is placed the front end of anesthetic laryngopharyngoscope, can be observed the intubate path that to see clearly with the general anesthesia laryngopharyngeal mirror, be installed on colour liquid crystal display device on the handle by observation and carry out the tracheal intubation operation and can significantly improve successful intubation.But, owing to there is complicated circuit to be connected,, be unfavorable for clinical soaking disinfection between the anesthetic laryngopharyngoscope that the electron image pick off has been installed and handle so can't dismantle.

The utility model content

Technical problem of the present utility model is that a kind of dismountable, dismountable electric video anesthetic laryngopharyngoscope that can carry out tracheal intubation operation under the indication that carries liquid crystal display will be provided, and has the video output function, outputting video signal is used for clinic to projector or large screen display show image.

In order to solve above technical problem, this utility model provides a kind of dismountable electric video anesthetic laryngopharyngoscope, comprises laryngoscope and handle, and buckle-type connects between laryngoscope and the handle, can dismantle, both electrical connections are connected by conductive contact after the clamping, and the laryngoscope front end has illuminating lamp and imageing sensor photographic head, and handle rear end has LCDs, flexibly connect between LCDs and the handle, can rotate and pitching translation-angle all around, the observation during handled easily each other.

Described laryngoscope is made of laryngoscope shell and case lid sealing, seal between the illuminating lamp of front end and the housing, imageing sensor photographic head, video signal processing circuit are installed in the housing, this treatment circuit is transformed to video signal with sensor signal, is connected with handle by the conductive contact on the laryngoscope then.

Conductive contact between described laryngoscope and the handle is video signal, positive source and power cathode.

Charging socket, video signal accessory power outlet, switch and display lamp are installed on the described LCDs shell.

The video signal of described laryngoscope output shows video by handle on liquid crystal display, externally show video on the display by VT simultaneously.

Superior effect of the present utility model is:

1) liquid crystal display and anesthetic laryngopharyngoscope are installed together, the colour liquid crystal display device that is installed on the handle by observation carries out the tracheal intubation operation, can be observed the intubate path that can't see clearly with the general anesthesia laryngopharyngeal mirror, has improved successful intubation greatly;

2) detachable between video laryngoscope and the handle, make things convenient for clinical disinfection;

3) image sensor and video signal processing circuit are installed in the laryngoscope housing together, have simplified the electrical connection of pick off, make its with handle between have only three conductive contacts to be connected, thereby realized detachable between video laryngoscope and the handle;

4) flexibly connect between LCDs and the handle, LCDs is translation-angle all around, the observation during handled easily.

5) video signal of laryngoscope output can be used for external display by VT, be convenient to medical teaching.

The specific embodiment

See also shown in the accompanying drawing, this utility model is done to describe further.

As depicted in figs. 1 and 2, this utility model provides a kind of dismountable electric video anesthetic laryngopharyngoscope, comprise laryngoscope 1 and handle 2, buckle-type connects between laryngoscope 1 and the handle 2, the connection bayonet socket 15 of laryngoscope 1 sticks into the connecting rod 22 of handle 2, and three conductive contacts 12 are connected with the contact spring 21 on the handle 2 after the clamping; Laryngoscope 1 front end has illuminating lamp 13 and imageing sensor photographic head 14, and there is LCDs 3 handle 2 rear ends, flexibly connects between LCDs 3 and the handle 2, can rotate and pitching translation-angle all around, the observation during handled easily each other.

Described laryngoscope 1 is made of laryngoscope shell 11 and case lid sealing, seal between the illuminating lamp 13 of front end and the housing 11, imageing sensor photographic head 14, video signal processing circuit are installed in the housing 11, this treatment circuit is transformed to video signal with sensor signal, is connected with handle 2 by the conductive contact 12 on the laryngoscope 1 then.
