Problems solved by technology

[0004] The problem is that although the blades used on the laryngoscope are generally replaceable disposable blades, some users will reuse the disposable blades after simple high-temperature disinfection in order to save costs or troubles, but The material of the existing disposable leaves cannot withstand high temperature or corrosion by disinfectant, and may produce harmful substances after high temperature disinfection, thus causing harm to medical staff and patients
Some users even simply wipe the leaves and use them again, which greatly increases the risk of cross-infection of patients

Abstract

The invention relates to the field of medical equipment, in particular to a blade self-destruct device and a laryngoscope, and aims to avoid reuse of used blades. The blade self-destruct device comprises a self-destruct bar, a self-destruct groove and a blade fixing part used for fixing a blade. One end of the self-destruct bar is rotatably connected with a handle through a rotary shaft, and the other end of the self-destruct bar is free. The blade fixing part is arranged at one end of the self-destruct bar, rotatably connected with the handle. The self-destruct groove is arranged between the handle and self-destruct bar connection and a handle and blade support connection. The laryngoscope comprises a blade support, the handle connected with the blade support, and the blade self-destruct device disposed on the handle. The self-destruct groove is reserved between the handle and self-destruct bar connection and the handle and support connection.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a blade self-destruct device and a laryngoscope. Background technique [0002] Laryngoscope, a device or instrument used to examine the larynx for lesions. It can be divided into indirect laryngoscope, direct laryngoscope, dynamic laryngoscope and fiberoptic laryngoscope. Indirect laryngoscopy uses the principle of mirror reflection to illuminate and observe the throat and larynx with a small round mirror with a handle. A direct laryngoscope is a hollow metal or plastic tube with a light at the end for direct illumination and observation of the pharynx and larynx. Dynamic laryngoscopy uses the light of the discharge tube as the light source, and observes the period, amplitude and phase changes of vocal cord vibration with indirect laryngoscope. It can also understand the difference between vocal cord vibrations on both sides that cannot be found by other laryngoscopes, which is...
