Oxygen supply and sputum suction device for respiratory medicine department

Abstract

The invention discloses an oxygen supply and sputum suction device for respiratory medicine department, belonging to the technical field of oxygen supply and sputum suction equipment. The oxygen supply and sputum suction device comprises a sputum suction device, an oxygen supply device and a sputum suction and oxygen supply pipe, wherein the sputum suction and oxygen supply pipe comprises a sputumsuction pipe and an oxygen supply pipe, the sputum suction pipe is arranged inside the oxygen supply pipe, and a gap exists between the sputum suction pipe and the oxygen supply pipe; a sealing ringsleeving the sputum suction pipe is arranged on the gas supply pipe and near the gas outlet end, and a plurality of oxygen nozzles are arranged on the sealing ring; the oxygen supply pipe is providedwith through holes corresponding to the oxygen nozzles, the sputum suction pipe is connected to the sputum suction device, and the oxygen supply pipe is connected to the oxygen supply device. The oxygen supply and sputum suction device of the invention not only realizes the continuous supply of oxygen, but also utilizes the introduced oxygen to separate the viscous sputum from the respiratory tract, thereby reducing the difficulty of sputum suction; moreover, the oxygen flow does not damage the respiratory mucosa, and the oxygen supply concentration is constant.

Description

technical field [0001] The invention relates to the technical field of oxygen supply and sputum suction equipment, in particular to an oxygen supply and sputum suction device for respiratory medicine. Background technique [0002] Sputum suction is an effective measure to clear up respiratory secretions. During the process of suctioning, the interruption of oxygen supply will lead to hypoxia or hypoxemia. Therefore, oxygen supply is required during the process of suctioning. High-flow, high-concentration oxygen is given before and after sputum, but it is impossible to give continuous oxygen while sucking sputum; secondly, for sticky sputum with relatively high viscosity, in the prior art, the method of injecting normal saline is used to dilute the sticky sputum or to increase the negative pressure. The method of suction absorbs mucus. Experience has proved that the effect of injecting normal saline to dilute mucus is not ideal, and increasing the negative pressure is easy to...

Problems solved by technology

[0002] Sputum suction is an effective measure to clear up respiratory secretions. During the process of suctioning, the interruption of oxygen supply will lead to hypoxia or hypoxemia. Therefore, oxygen supply is required during the process of suctioning. High-flow, high-concentration oxygen is given before and after sputum, but it is impossible to give continuous oxygen while sucking sputum; secondly, for sticky sputum with relatively high viscosity, in the prior art, the method of injecting normal saline is used to dilute the sticky sputum or to increase the negative pressure. The way of suction is to absorb mucous phlegm. Practical experience has proved that the effect of injecting normal saline to dilute mucus phlegm is not ideal, and increasing the negative pressure is easy to cause damage to the respiratory mucosa. Therefore, it is necessary to provide a device that can quickly suck out mucus.
