Abstract
The utility model relates to an electronic video laryngoscope anti-fog device. The electronic video laryngoscope anti-fog device is characterized in that the electronic video laryngoscope anti-fog device is composed of a heating component which is installed on the front end of a camera component, the heating component is composed of a circuit board and a heating element which is installed on the circuit board, and the heating element is embedded in a protective cover of a camera lens. Due to the fact that the heating component is arranged at the front end of the camera component, the electronic video laryngoscope anti-fog device is capable of preheating an end of a laryngoscope lens before the laryngoscope lens enters a throat, thereby reducing difference in temperature of the laryngoscope lens after the laryngoscope lens enters throat, avoiding formation of fog at the end of the laryngoscope lens and ensuring definition and accuracy of videoing of the camera component.
Description
Technical field
This utility model relates to electric video laryngoscope, particularly for the anti-smog device on electric video laryngoscope.
Background technology
Existing electric video laryngoscope; particularly the electric video laryngoscope with the disposable laryngoscope sheet comprises disposable laryngoscope blade 5, laryngoscope blade support bar 6, operating grip and display screen; front end at the laryngoscope blade support bar is built-in with camera assembly and light fixture, at port the cam lens over cap is installed.This electric video laryngoscope is sleeved on disposable laryngoscope blade on the laryngoscope blade support bar in use, then with disposable laryngoscope blade partial insertion in throat.Because there is the temperature difference in the inside and outside, cause the end 5-1 of laryngoscope blade, the position that namely aligns with the cam lens over cap water smoke occurs, thereby has reduced definition and the accuracy of camera assembly recording.
Summary of the invention
This utility model provides a kind of electric video laryngoscope anti-smog device for solving the technical problem that exists in the known technology, and this anti-smog device has been avoided forming water smoke in the end of disposable laryngoscope blade, and then has guaranteed definition and the accuracy of camera assembly recording.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
The electric video laryngoscope anti-smog device is characterized in that: be made of the heating component that is installed in the camera assembly front end, described heating component is made of circuit board and the upper heating element heater that is installed in circuit board, and described heating element heater is inlaid in the cam lens over cap.
The technical scheme that this utility model can also be taked is:
Described heating element heater is two, and is arranged symmetrically in up and down both sides or the left and right sides of camera aperture.
Described heating element heater is the strip heating element heater.
Described heating element heater is the annular-heating element, and is arranged on one heart the outside of camera aperture.
Advantage and the good effect that the utlity model has are:
This utility model is by arranging heating component at the camera assembly front end, can before entering throat, laryngoscope blade carry out preheating to its end, thereby reduced the temperature difference after laryngoscope blade enters throat, avoided forming water smoke in the end of laryngoscope blade, guaranteed definition and the accuracy of camera assembly recording.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is user mode reference diagram of the present utility model;
Fig. 3 is the structural representation that disposable laryngoscope blade cooperates with the laryngoscope blade support bar.
Among the figure: 1, circuit board; 2, heating element heater; 3, camera assembly; 3-1, camera aperture; 4, cam lens over cap; 4-1, opening; 5, disposable laryngoscope blade; 5-1, end; 6, laryngoscope blade support bar.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-2; the electric video laryngoscope anti-smog device; be made of the heating component that is installed in camera assembly 3 front ends, described heating component is made of circuit board 1 and the heating element heater 2 that is installed on the circuit board, and described heating element heater is inlaid in the cam lens over cap 4.Concrete, be provided with the opening 4-1 of setting-in heating element heater at the cam lens over cap.
In the technique scheme: quantity and the position of heating element heater are unrestricted, can arrange according to the construction features of camera assembly and disposable laryngoscope blade.In this utility model, described heating element heater is preferably as follows two schemes:
The first scheme is: described heating element heater is two, and is arranged symmetrically in up and down both sides or the left and right sides of camera aperture 3-1.Heating element heater is the strip heating element heater more preferably.This structure is referring to accompanying drawing.
First scheme is: described heating element heater is the annular-heating element, and is arranged on one heart the outside of camera aperture.
