DETAILED DESCRIPTION OF THE EMBODIMENTS

Example 1

As shown inFIG.1andFIG.4, a video laryngoscope with a guided decontamination device comprises a laryngoscope handle1and a video laryngoscope blade2. The front end of the video laryngoscope blade2is equipped with a light source7and a camera8. The laryngoscope handle1is equipped with a display screen9connected with the camera8. The guided decontamination device included is composed of a guide tube10and a decontamination rod14. The guide tube10is fixed on the outer wall of the laryngoscope handle1, and has its guiding angle in parallel to the end faces of the camera8and the light source7at the front end of the laryngoscope blade. The decontamination rod14comes into a sliding fit with the guide tube10. The guide tube10has its upper segment acting as a spring chamber11, and its lower segment acting as a guide chamber12, the diameter of the spring chamber11is larger than that of the guide chamber12. A reset spring13is assembled in the spring chamber11. The decontamination rod14runs out from the bottom of the guide tube10upwards, and has its front end bent to form a decontamination scraper rod15. The decontamination scraper rod15comes into a tight fit with the end faces of the light source7and the camera8at the front end of the laryngoscope blade. The inner sidewall of the front end of the video laryngoscope blade2is provided with a decontamination scraper rod guide groove19where one end of the decontamination scraper rod15is assembled. The decontamination scraper rod15is guided through sliding fit in the decontamination scraper rod guide groove19, and the decontamination scraper rod guide groove19is parallel to the end faces of the camera8and the light source7to ensure a tight fit between the decontamination scraper rod15and the end faces of the camera8and the light source7. A decontamination rod button20is arranged at the upper end of the decontamination rod14and has one end arranged in the spring chamber11and the other end exposed outside the spring chamber11. The outer wall of the video laryngoscope blade2is provided with a limit snap ring17, which is movably inserted in the video laryngoscope blade2to form a decontamination rod limit chamber18between the limit snap ring17and the outer wall of the video laryngoscope blade2. The decontamination rod14is arranged movably in the decontamination rod limit chamber18. The decontamination scraper rod15is provided with a decontamination rubber hose16. The decontamination rod14is a metal wire with a diameter of 2 mm or so.

Example 2

As shown inFIG.2,FIG.3andFIG.4, a video laryngoscope with a guided decontamination device comprises a laryngoscope handle1and a disposable video laryngoscope blade3. The disposable video laryngoscope blade3comprises a laryngoscope blade inner cavity high-transparency closed end5for a camera to capture images and a light source to pass. The laryngoscope handle1is provided with a display screen9connected with a camera8. The guided decontamination device included is composed of a guide tube10and a decontamination rod14. The guide tube10is fixed on the outer wall of a tail end of the main body of the disposable video laryngoscope blade3, and has its guiding angle in parallel to the end face of the laryngoscope blade inner cavity high-transparency closed end5. The decontamination rod14comes into a sliding fit with the guide tube10. The guide tube10has its upper segment acting as a spring chamber11, and its lower segment acting as a guide chamber12, the diameter of the spring chamber11is larger than that of the guide chamber12, and a reset spring13is assembled in the spring chamber11. The decontamination rod14runs out from the bottom of the guide tube10upwards, and has its front end bent to form a decontamination scraper rod15. The decontamination scraper rod15is tightly fitted with the end face of the laryngoscope blade inner cavity high-transparency closed end5. An extension arm101is further included. The disposable video laryngoscope blade3comprises a laryngoscope blade inner cavity4and a tongue depressor6. The rear end of the laryngoscope blade inner cavity4is open, and the laryngoscope blade inner cavity4is inserted on the extension arm101. The sidewall of the front end face of the laryngoscope blade inner cavity4is provided with a decontamination scraper rod guide groove19where one end of a decontamination scraper rod15is assembled. The decontamination scraper rod15is guided through sliding fit in the decontamination scraper rod guide groove19, and the decontamination scraper rod guide groove19is parallel to the end face of the laryngoscope blade inner cavity high-transparency closed end5to ensure tight fit between the decontamination scraper rod15and the end face of the laryngoscope blade inner cavity high-transparency closed end5. A decontamination rod button20is arranged at the upper end of the decontamination rod14, and has one end arranged in the spring chamber11and the other end exposed outside the spring chamber11. The outer wall of the video laryngoscope blade2is provided with a limit snap ring17, which is movably inserted on the video laryngoscope blade2to form a decontamination rod limit chamber18between the limit snap ring17and the outer wall of the video laryngoscope blade2, and the decontamination rod14is arranged movably in the decontamination rod limit chamber18. The decontamination scraper rod15is provided with a decontamination rubber hose16. The decontamination rod14is a metal wire with a diameter of 2 mm or so.
