Disposable-intubation bougie-containing video laryngoscope

Abstract

The invention discloses a disposable intubation bougie-containing video laryngoscope. The disposable intubation bougie-containing video laryngoscope comprises an intubation bougie, a handle and a liquid crystal display. A micro camera used in the intubation bougie is a complementary metal oxide semiconductor (CMOS) image acquisition chip with resolution of 70,000 to 100,000 pixels, so that the manufacturing cost of the intubation bougie is greatly reduced; a locking structure is arranged at the junction of the intubation bougie and the handle, so that the connection between the intubation bougie and the handle is detachable, stable and reliable and is not loose; and a glass flat plate coated with an antireflection film is arranged in front of the micro camera, so that the consistency of imaging of the micro camera in air or body fluid is ensured. The cheap intubation bougie can be discarded without being completely sterilized after being used once. The video laryngoscope is particularly suitable for endotracheal intubation monitored by the video laryngoscope which is implemented in ambulances and emergency rooms of hospitals.

Description

technical field [0001] The invention relates to a video laryngoscope with a disposable intubation bougie, which belongs to the technical field of laryngoscopes of medical instruments. Background technique [0002] Endotracheal intubation is a common technique used in first aid and anesthesia work to keep a patient's breathing open. Tracheal intubation can be achieved by using an ordinary "L"-shaped video laryngoscope, but since the working blade of the "L"-shaped video laryngoscope occupies a large space in the oral cavity, and the working blade needs to be inserted from the midline of the oral cavity, when working from the When the endotracheal tube is inserted on the right side of the blade, the cuff site of the endotracheal tube often becomes lodged between the right side of the working blade and the right molar. In this case, it is necessary to further increase the strength of lifting the laryngoscope to increase the opening of the patient, which will cause more obvious...

AI Technical Summary

Problems solved by technology

But this bougie still has the following disadvantages: the first, the maximum outer diameter of the camera device of this bougie is no more than 2mm, the resolution of the image acquisition chip is generally very high, and the price is expensive; the second, there is no locking on the male end structure, so that the connection between the bougie and the handle is a loose connection, and the reliability is poor; third, the electronic components in the bougie cannot withstand high-temperature and high-pressure disinfection, that is, the bougie cannot meet the requirements of thorough disinfection, and there must be some triggers. The hidden danger of cross-infection of patients; Fourth, the front end of the camera device is not packaged with a flat glass film, resulting in inconsistent imaging of the camera device in air or body fluids, and it is necessary to improve it
