Description
Technical field
This utility model relates to a kind of video laryngoscope that contains disposable intubate bougie, belongs to the technical field of the laryngoscope of medical apparatus and instruments.
Background technology
Endotracheal intubation is a technology commonly used in first aid and the anesthesia work, is intended to keep patient's breath unobstructed.Use common " L " type video laryngoscope can realize endotracheal intubation; But because that the working-blade of " L " type video laryngoscope occupies the space in oral cavity is bigger; And working-blade need insert from the center line in oral cavity; So when inserting endotracheal tube from the right side of working-blade, the cover capsule position of endotracheal tube usually can be stuck between working-blade right side and the right side distomolar.In such cases, need further to increase the strength of carrying laryngoscope, to increase patient's opening degree, oral cavity and the pharyngeal to the patient can cause comparatively significantly stimulation like this.
When " L " type of employing video laryngoscope is implemented endotracheal intubation; Also assist its front end subtend glottis in order to make the endotracheal tube front end walk around crooked laryngoscope blade; Must in endotracheal tube, insert intubating stylet, after the endotracheal tube front end gets into glottis, pull out intubating stylet by the assistant with certain elasticity and hardness; And then endotracheal tube inserted in the trachea, this will prolong the endotracheal tube front end undoubtedly in throat time that stops and the stimulation that increases throat.And, cause repeatedly repeating intubate, even cause malpractice toward the contact probability that endotracheal tube is pulled out simultaneously when having the plug tube core.
A kind of intubate bougie is arranged in the background technology, need handle coupling with video laryngoscope.This bougie is a thin metal pipe; One end of thin metal pipe curves an insertion end, is provided with photographic attachment and LED lamp in the port of insertion end, and the other end of thin metal pipe is provided with public end; This bougie is inserted with the female termination on the handle with removably through public end and is connected; Guarantee that photographic attachment and LED lamp can obtain power supply from handle, guarantee that photographic attachment is sent to handle with the picture signal that photographs, and is presented on the screen of display device.In the intubate process, the LED lamp is that photographic attachment provides illumination, and photographic attachment is sent to handle with the picture signal that photographs, and is presented on the screen of display device, and the healthcare givers watches the situation of intubate through screen, fast and correctly endotracheal tube is inserted trachea.But this bougie still has following shortcoming: the first, and the maximum outside diameter of the photographic attachment of this bougie is no more than 2mm, and the resolution of image collection chip is generally very high, costs an arm and a leg; The second, there is not locking mechanism on the public end, make this bougie be connected poor reliability with being connected to of handle is loosening; The 3rd, the electronic devices and components in this bougie can not the withstand high temperatures autoclave sterilization, and promptly this bougie can not satisfy the requirement of thorough disinfection, must have the hidden danger that causes patient's cross infection; The 4th, the front end of camera head does not have the packaged glass plain film, and it is inconsistent to cause camera head in air or body fluid, to form images, and improved necessity is in addition arranged.
Summary of the invention
For overcoming the defective of the video laryngoscope that contains above-mentioned intubate bougie, the purpose of this utility model provides a kind of video laryngoscope that contains disposable intubate bougie.
