Description

Portable electronic video laryngoscope

technical field

The utility model relates to a tracheal intubation laryngoscope for electronic imaging of the larynx, in particular to a convenient electronic video laryngoscope for anesthesia tracheal intubation.

Background technique

Existing tracheal intubation laryngoscope is made of mirror handle, tongue depressor and flange.

For example, the patent Nos. CN03264840.5 and CN200520041786.8 are utility model patents, both of which are composed of an operating handle that doubles as a battery box and a tongue depressor. The light source is a small light at the front of the spatula. . This type of laryngoscope is simple in structure and easy to disinfect, so it is widely used in routine tracheal intubation. However, this type of laryngoscope has insufficient illumination; the arc-shaped spatula of the Macintosh lens used sometimes makes it difficult to expose the glottis well; the visual field is easily limited by the curvature of the spatula, which makes tracheal intubation difficult and endangers the patient's life; the success rate of intubation It relies heavily on the proficiency of the anesthesiologist, and the glottis needs to be observed at a very close distance during intubation. The patient's body fluids and secretions are easy to contaminate the operator of the endotracheal intubation.

For example, the utility model patents with patent Nos. CN02278346.6 and CN 02251134.2 are a kind of Mccoy laryngoscope whose spatula tip can be bent. Although the epiglottis can be raised better, the visual field is limited by the radian of the spatula. The glottis cannot be observed well, and the tip of the laryngoscope is easy to squeeze the local tissue during the movement, causing bleeding and edema, and because the glottis needs to be observed closely, there is a possibility that the anesthetist may be contaminated.

For example, the utility model patent with the patent number CN200520106648.3 is a visual indirect laryngoscope, which is composed of a video laryngoscope handle and a display device. The handle is connected to the display device through a data cable, which can clearly display the status of the larynx and airway opening , to guide the intubation in place quickly and accurately, ensuring that no damage is caused to the patient during the intubation process. However, this laryngoscope has the following defects: the display device and the handle are designed separately, and the volume is large, so it must be placed beside the operating bed, so that the line of sight of the anesthesiologist and the direction of the tracheal intubation are not on the same axis, which brings inconvenience to the operation of the anesthesiologist. inconvenient.

For example, the utility model patents whose patent numbers are CN200820057809.8 and CN200620138578.4, the laryngoscope and the handle of this type of visual anesthesia laryngoscope are connected by a buckle, and the rear end or side rear end of the handle is connected with a rotatable liquid crystal display Screen. The disadvantage of this type of laryngoscope is that the handle length is too long. When intubating some patients with limited neck movement or obese patients with high thorax, the handle of the laryngoscope is easy to reach the patient's chest, making it difficult to insert the laryngoscope; It is not suitable for patients with infectious diseases because it is directly exposed and the camera is directly exposed. Moreover, the temperature of the light source is higher than that of the human body, which makes the surface of the directly exposed camera lens easy to condense and fog, resulting in unclear video images.

For example, the patent No. CN200910050547.1 utility model patent, the electronic video multifunctional laryngoscope introduced has many parts, and the assembly process before each use is more complicated; before the spatula is sterilized, the camera assembly needs to be removed and installed repeatedly Disassembly will easily lead to poor contact between the bracket assembly and various parts, which will affect the service life; the battery compartment is designed horizontally as a holding part, although the length of the mirror handle is shortened, but the horizontal holding is not convenient for the anesthesiologist to lift up the epiglottis when intubating, and its The moment arm is short and the operation is laborious.

Contents of the invention
