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
The present invention relates to a kind of video laryngoscope that contains disposable intubate bougie, belong 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 breathing 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 with certain elasticity and hardness, after the endotracheal tube front end enters glottis, pull out intubating stylet by the assistant, and then endotracheal tube inserted in the trachea, this will prolong the time that the endotracheal tube front end stops in throat undoubtedly and increase stimulation to 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, be provided with photographic attachment and LED lamp in the port of insertion end, the other end of thin metal pipe is provided with male end, this bougie patches with removably and female end on the handle by male 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 provides illumination for photographic attachment, 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 by 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 male 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, causes camera head imaging in air or body fluid inconsistent, 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 invention is to provide a kind of video laryngoscope that contains disposable intubate bougie.
