Description

  The present invention relates to a tracheal intubation device for observing the inside of the larynx, a small camera wireless system for tracheal intubation that is mounted on the tracheal intubation device and photographed. Compact camera wireless system for tracheal intubation featuring compact image sensor, small camera control, small transmitter, small battery, power switch, compact cordless specification and detachable specification, operability, commonality and improved cleanliness Is.

  Conventional tracheal intubation devices have been used for intubation of endotracheal tubes, etc. in order to treat diseases by observing humans and animals in the larynx and to secure the airways of people and animals who are unable to breathe spontaneously. In addition, since the tracheal tube is intubated into the trachea based on the experience and intuition of the doctor, the tracheal tube cannot be inserted accurately at the time of intubation, and there are many troubles that damage the throat, trachea and vocal cords.

  Therefore, recently, a tracheal intubation camera system is used for intubation of the tracheal tube, and the configuration is composed of an optical fiber bundle serving as a light guide, a lens, and an image sensor, which transmits the observation image in the larynx and sends a video signal from the camera control. The video can be output to a TV monitor via a camera cable. (See JP 2000-175867 A)

  However, the conventional tracheal intubation camera system described above is formed integrally with an image sensor that takes an image together with a light guide made of an optical fiber to illuminate the inside of the larynx, so that rigidity is increased and flexibility is deteriorated. The system was expensive and difficult to use because it could not be applied.

  In addition, since the observation video captured by the imaging device is transmitted and the video signal is output from the camera control to the TV monitor with the camera cable specification, even if the tracheal intubation camera system is a battery specification, the tracheal intubation Since the camera cable is used when the camera system is used, there is a problem in that the operability is deteriorated because it becomes an obstacle during the operation.

  In addition, the lens, illumination unit, imaging device, control unit, battery, power switch, and all camera system units are built into the tracheal intubation device, and the camera system unit cannot be attached or detached because it is integrated. A camera system for tracheal intubation tailored to the individual larynx of humans and animals is required, making it impossible to share the camera system part. Also, in terms of hygiene, it takes time and effort to sterilize, and cleanliness There was a problem that could not be improved.

  Therefore, the present invention has been made to solve such a conventional problem. The purpose of the present invention is to observe the inside of the larynx at a high resolution, and at the same time, improve the operability from cordless, and intubate the trachea. The purpose of this invention is to provide a small camera wireless system for tracheal intubation in which a small camera wireless system unit is made common by the attachment / detachment specification from the appliance and the cleanliness can be improved.
