Disposable Visual Laryngoscope machine

The disposable video laryngoscope is a sterile, single-use airway management device, mainly used for tracheal intubation and upper respiratory tract examination. It integrates a high-definition camera and lighting system to provide clinicians with a clear view of the glottis, significantly improving the success rate of intubation, and is particularly suitable for difficult airway management.

1. Core structure and technical features

(1) Mirror body design

High-definition camera: micro CMOS sensor integrated at the front of the lens (resolution is usually 720P-1080P)

LED cold light source: low heat damage, adjustable brightness (30,000-50,000 lux)

Ergonomic: lens angle 60°-90°, reducing the risk of tooth damage

Anti-fog treatment: special coating or flushing channel design

(2) Display system

Portable host: 4.3-7 inch LCD screen, some support wireless transmission

Fast focus: automatic/manual focus adjustment (3-10cm)

(3) Disposable components

Lens, light source module, anti-pollution kit are packaged as a whole

Optional disposable blades (different models: Mac/Miller/straight)

2. Main clinical application scenarios

(1) Conventional endotracheal intubation

Airway establishment during general anesthesia surgery

Rapid intubation in the emergency department

ICU airway management

(2) Difficult airway management

Patients with limited cervical spine motion

Cases with mouth opening <3 cm

Mallampati grading level III-IV

(3) Other applications

Upper respiratory tract foreign body removal

Laryngeal examination teaching

Battlefield/disaster medical rescue

3. Advantages compared with traditional laryngoscopes

Parameters Disposable visual laryngoscope Traditional metal laryngoscope

Cross-infection risk Completely eliminated Depends on disinfection quality

Intubation success rate >95% (especially difficult airway) About 80-85%

Preparation time Ready to use after unpacking (<30 seconds) Disinfection preparation required (5-10 minutes)

Learning curve Shorter (mastery in about 10 cases) More than 50 cases of experience required

Cost 300-800 yuan per time Initial equipment is expensive but reusable

4. Precautions for operation

Pre-oxygenation: Ensure adequate oxygen supply before intubation

Posture adjustment: "Flower sniffing position" is the best

Anti-fog treatment: Soak in warm water or anti-fog agent before use

Force control: Avoid excessive force on the front teeth

Waste disposal: Dispose of as infectious medical waste

It is gradually becoming the standard configuration of emergency departments and anesthesia departments, especially in the context of global epidemic prevention and control, the demand has increased significantly.
