Electronic laryngoscope with continuous air injection function

Abstract

The electronic laryngoscope with the continuous air injection function comprises an intubation tube and an air injection assembly, the intubation tube is bendable and internally provided with a ventilation cavity, the outer wall of the ventilation cavity is communicated with a connecting port, one end of the intubation tube is connected with a digital display screen through a connector, a digital display assembly is integrated in the connector, and the interior of the intubation tube is connected with the connector by arranging a transmission cable. The air injection assembly comprises multiple sets of air guide grooves evenly formed in the free end of the insertion pipe in the axis direction of the insertion pipe, each set of air guide grooves are evenly distributed in the circumferential direction and communicate with the ventilation cavity at the same time, elastic cover plates are connected to the top faces of the air guide grooves, sealing plates are arranged on the bottom faces of the air guide grooves, and the bottom ends of the elastic cover plates make contact with the top faces of the sealing plates. The free end of the insertion pipe is sleeved with an air guide assembly. The gas injection assembly can be used in cooperation with the gas guide assembly and the supporting assembly, so that the device can adjust the expanding length according to the requirement, and meanwhile, the situation that a traditional device directly injects gas downwards, and consequently the abdominal cavity of a patient is pneumatosis can be avoided.
