Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable split laryngoscope. Background Art

[0002] Disposable laryngoscope blades are usually used in conjunction with video laryngoscopes for one-time use in clinical assistance for tracheal intubation. After fixing the video laryngoscope and the disposable laryngoscope blade, the front camera part is inserted deep into the patient's laryngeal cavity with the help of the curvature of the laryngoscope blade, thereby achieving the purpose of tracheal intubation by directly observing the patient's laryngeal cavity.

[0003] Authorization publication number "CN215078277U" records "a disposable laryngoscope blade, comprising a sleeve, a tongue depressor and a guide plate, the upper surface of the guide plate, the upper surface of the tongue depressor and the upper surface of the sleeve are smoothly connected, the tongue depressor is provided with a first tilt and a second tilt along the extension direction of the upper surface of the sleeve, the first tilt and the second tilt are smoothly transitioned through a rounded corner, the first tilt is arranged at an end close to the sleeve, and the second tilt is arranged at an end away from the sleeve. The utility model provides a laryngoscope blade with two tilts on the tongue depressor portion, wherein the angle of the second tilt is larger than the angle of the first tilt, and the length of the upper surface of the first tilt is larger than the length of the upper surface of the second tilt, and the second tilt can provide a larger angle, so that patients with difficult airway can be intubated smoothly under the guidance of the second tilt of the laryngoscope blade, so the laryngoscope blade provided by the utility model can be used for both ordinary patients and patients with difficult airway".

[0004] The above patent can be used for both ordinary patients and patients with difficult airway. However, the existing disposable laryngoscope blade requires medical staff to pull the handle upwards to lift the laryngoscope blade as a whole to expose the laryngeal cavity, and in order to avoid damaging the patient's oral cavity, it must be pulled vertically when in use, and cannot be lifted up with the help of a fulcrum. There is a problem that it is difficult to exert force and it is easy to violently damage the patient's teeth, tongue and other parts. For this reason, we propose a disposable split laryngoscope blade. Utility Model Content
