Oxygen supply and sputum suction device for respiratory medicine

Abstract

The invention discloses an oxygen supply and sputum suction device for respiratory internal medicine, which belongs to the technical field of oxygen supply and sputum suction equipment. The oxygen supply and sputum suction device includes a sputum suction device, an oxygen supply device and a sputum suction oxygen supply tube, the sputum suction and oxygen supply tube includes a sputum suction tube and an oxygen supply tube, and the sputum suction tube is arranged inside the oxygen supply tube, There is a gap between the sputum suction tube and the oxygen supply tube, the oxygen supply tube is provided with a sealing ring sleeved on the sputum suction tube near the outlet end, and the sealing ring is provided with a plurality of oxygen nozzles; The oxygen supply tube is provided with a through hole corresponding to the oxygen nozzle, the sputum suction tube is connected to the sputum suction device, and the oxygen supply tube is connected to the oxygen supply device. The oxygen supply and sputum suction device of the present invention not only realizes the continuous supply of oxygen, but also uses the oxygen to separate mucus from the respiratory tract, reducing the difficulty of sputum suction. At the same time, the oxygen flow will not damage the mucous membrane of the respiratory tract, and it can also achieve a constant oxygen supply concentration. .

Description

Technical field[0001]The invention relates to the technical field of oxygen-supplying sputum suction equipment, in particular to an oxygen-supplying sputum suction device for respiratory medicine.Background technique[0002]Sputum suction is an effective measure to clean up the secretions of the respiratory tract. During the suction process, the interruption of oxygen supply will cause hypoxia or hypoxemia. Therefore, oxygen supply is required during the suction process. In the prior art, suction is often used. High-flow and high-concentration oxygen is given before and after the sputum, but it is impossible to give continuous oxygen while sucking the sputum. Secondly, for the thick sputum with a relatively large viscosity, the prior art adopts the method of injecting normal saline to dilute the sputum or increase the load. The pressure method absorbs mucous sputum. Practical experience has proved that the effect of injecting physiological saline to dilute mucous sputum is not ideal, ...

AI Technical Summary

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.
