Problems solved by technology

In addition, in general suction pumps, since suction is continuously performed at a constant suction pressure, the suction flow rate cannot be adjusted.
[0010] However, the required suction flow rate differs depending on the viscosity and amount of the foreign body, so continuous suction with an unnecessarily large suction flow rate will also cause injury to the mucous membrane in the trachea, which will place a heavy burden on the patient

Abstract

The present invention provides a suction connector capable of easily adjusting the suction flow rate and a tracheal tube provided with same. This suction connector is inserted into the respiration pathway of a main tracheal tube body connected to an artificial respirator and is provided with a suctioning section for suctioning substances inside the body and a flow rate-adjusting section for adjusting the suction flow rate by adjusting the area of the suction channel of the suctioning section. The suction flow rate for foreign matter such as sputum that is generated inside the body can thereby be easily adjusted by the flow rate-adjusting unit.

Description

technical field [0001] The present invention relates to a suction connector having a suction catheter connected to a suction device such as a suction pump and used to continuously suck saliva, sputum secreted from the lungs or bronchi and other foreign substances, and an endotracheal tube equipped with the suction connector. Background technique [0002] Conventionally, artificial respiration has been performed for patients whose spontaneous breathing is insufficient using an artificial respirator. The artificial respirator is connected to an intubation device such as an endotracheal tube inserted into the trachea from the mouth or a tracheostomy tube inserted into the trachea through a tracheostomy hole, and the breathing of the patient is ensured through the intubation device. [0003] However, patients who have been inserted with intubation devices such as endotracheal tubes and tracheostomy tubes cannot expel sputum, saliva, etc. accumulated in the trachea, bronchi, etc....
