AI Technical Summary

Technical Problem

Existing laryngeal nebulizers have a constant initial spray kinetic energy and anesthetic spray range, which are easily affected by the patient's breathing airflow, gravity, and the complex structure of the oral cavity. This makes it difficult for the anesthetic to accurately reach the target area, resulting in inaccurate anesthetic range and waste of anesthetic, affecting the effectiveness and safety of use.

Method used

An air curtain assembly provides airflow-assisted nozzles. By adjusting the direction and range of the airflow, it ensures that the anesthetic reaches the target area accurately and efficiently, reducing waste in non-target areas. The assembly includes an inner and outer tube structure, utilizes an elastic cylinder and magnetic ring support rod to adjust the airflow, and combines an air pump and nozzle design to form a ring-shaped high-speed airflow that envelops the drug droplets, providing guidance and power.

Benefits of technology

It enables targeted and accurate delivery of anesthetics, reduces waste, improves anesthetic efficacy and safety, reduces patient discomfort, expands the scope of application, is suitable for different surgical wounds, and improves operational flexibility and safety.

Abstract

The invention relates to an adjustable spraying device for clinical anesthesia in the anesthesiology department, and belongs to the technical field of medical instruments. In order to enable anesthetics to accurately and efficiently reach a target anesthesia area, the adjustable and controllable spraying device for clinical anesthesia in the anesthesiology department comprises a spraying pipe and an air curtain assembly, the spraying pipe comprises an inner pipe and an outer pipe, a plurality of spraying holes are formed in the tail end of the inner pipe, the inner pipe is sleeved with the outer pipe, and an air conveying cavity communicated with an air pump is formed between the outer pipe and the inner pipe; the air curtain assembly comprises an elastic cylinder arranged in the air conveying cavity, one end of the elastic cylinder is configured to move in the direction close to or away from the inner pipe so as to change the flowing direction and the flowing range of airflow in the air conveying cavity, and the other end of the elastic cylinder is slidably connected with the inner pipe. The air curtain assembly can control the anesthetic spraying direction and spraying range, the anesthetic can accurately and efficiently reach the target anesthesia area, the spraying range is controlled within the target anesthesia area, anesthetic waste is reduced, and the anesthesia effect and anesthesia safety are improved.
