Laryngoscopic device

摘要

A laryngoscopic device includes a laryngoscope video blade and a handle module arranged to support the video blade or auxiliary direct laryngoscopy blades interchangeably thereon. The video blade includes a camera and contacts for receiving electrical power from the handle module while outputting video to the handle module from the camera. The handle module can also provide electrical power to a light source on the video blade or include its own light source to be conveyed to a light guide of a blade coupled to the handle module. The laryngoscopic device also includes a display monitor which can be removably coupled to an output of the handle module to display video generated by the video blade camera. The handle module can be used alone with non-video blades or readily converted to a video laryngoscopic device by replacing the non-video blade with a video blade and connecting the display monitor.

主权项

1. A laryngoscopic device, the device comprising:
a laryngoscope video blade comprising:
an elongate body portion spanning between a coupling portion at a first end and a tip portion at an opposing second end so as to be arranged for insertion into an airway opening of a patient, the coupling portion including a positive contact, a negative contact, and a video output contact; anda camera supported on the body portion adjacent the tip portion so as to be arranged to generate a video signal, the camera being operatively connected to the positive contact, the negative contact, and the video output contact of the coupling portion of the laryngoscope video blade; an electrical power source including positive and negative terminals; a monitor module comprising a housing having a coupling portion and a video display monitor; and a handle module which is elongate between a working end and an opposing gripping end suited for gripping in a hand of a user; the working end of the handle module having a first coupling portion thereon in mating connection with the coupling portion of the laryngoscope video blade in a coupled position, the first coupling portion of the handle module and the coupling portion of the video blade being readily separable from one another from the coupled position so as to enable ready separation of the laryngoscope video blade from the handle module; the first coupling portion at the working end of the handle module including a positive contact, a negative contact and a video output contact supported thereon which are mated with respective ones of the positive contact, the negative contact and the video output contact of the laryngoscope video blade in the coupled position of the laryngoscope video blade with the handle module; the positive contact, the negative contact, and the video output contact of the working end of the handle module being separable from respective ones of the positive contact, the negative contact, and the video output contact of the laryngoscope video blade together with separation of the first coupling portion of the handle module from the coupling portion of the laryngoscope video blade; and the gripping end of the handle module having a second coupling portion thereon in mating connection with the coupling portion of the monitor module in a coupled position, the second coupling portion of the handle module and the coupling portion of the monitor module being readily separable from one another from the coupled position so as to enable ready separation of the monitor module from the handle module; the second coupling portion of the gripping end of the handle module including a video output which is adapted to communicate the video signal of the camera to the video display monitor in the coupled position so as to be arranged to display the video signal generated by the camera on the video display monitor; the video output of the handle module being separable from the video display monitor together with separation of the second coupling portion of the handle module from the coupling portion of the monitor module; the handle module further comprising a positive electrical conduit communicating between the positive contact of the working end of the handle module and the positive terminal of the power source, a negative electrical conduit communicating between the negative contact of the working end of the handle module and the negative terminal of the power source, and a video output conduit communicating between the video output contact at the working end of the handle and the video output at the gripping end of the handle module.
