Built-in sputum aspirator for severe surgery tracheostomy sleeve

Abstract

The invention discloses a sputum aspirator with a built-in tracheostomy sleeve for severe surgery, and relates to the technical field of sputum aspiration equipment. The sputum aspirator comprises a cannula assembly and a sputum aspiration assembly, the cannula assembly comprises a tracheal cannula, and a guide support is arranged in the tracheal cannula. The sputum suction assembly comprises a suction pipe and a shaped metal guide wire. A plurality of sputum suction holes are uniformly formed in one side of the bent part of the suction pipe; the other side, opposite to the sputum suction hole, of the bent part of the suction pipe is of a corrugated structure; the two ends of the suction pipe communicate with a feeding unit and a recycling unit correspondingly. The trachea cannula has the advantages that the suction tube is suspended in the respiratory tract without affecting ventilation balance after being inserted into the respiratory tract through the metal guide wire and the trachea cannula, so that the suction tube can be retained for a long time, repeated intubation is avoided, sputum suction efficiency is improved, negative pressure scratching to the respiratory tract is avoided due to the micropore design of the sputum suction holes, and the sputum suction effect is good. And the diluent flows along the suction tube to prevent sputum from blocking the sputum suction hole, so that the use is smoother.

Description

technical field [0001] The invention relates to the technical field of sputum suction equipment. Background technique [0002] When treating and nursing critically ill patients, the increased secretion of sputum can easily lead to airway blockage and cause suffocation. Therefore, it is necessary to perform sputum suction treatment. Traditionally, tracheotomy is used to insert a tracheal cannula into the patient's airway through a tracheotomy. When performing intubation and suctioning, it is necessary to control the time of suctioning sputum, that is, it takes no more than 15 seconds for sputum suction at a time, and when the sputum cannot be sucked clean at one time, multiple suctioning operations are required, so it is necessary to repeat sputum suctioning. Repeated intubation and extubation operations waste a certain amount of time, and when the sputum is relatively viscous, diluent needs to be injected, which will affect the operation time of sputum suction, reduce the su...

Problems solved by technology

[0002] During the treatment and nursing of critically ill patients, the increased secretion of sputum may easily block the respiratory tract and cause suffocation. Therefore, the patient needs to be treated with sputum suction. Traditionally, the tracheal tube is inserted into the patient's respiratory tract through a tracheotomy through a tracheal incision. And when intubating sputum suction, it is necessary to control the time of sputum suction, that is, it is necessary to suck sputum for no more than 15 seconds at a time, and when the sputum cannot be sucked clean at one time, it is necessary to perform multiple suction operations, so it is necessary to repeat the sputum suction. Repeated intubation and extubation operations waste a certain amount of time, and diluent injections are required when the sputum is relatively viscous, which affects the working time of sputum suction and reduces the effect and efficiency of sputum suction. When sucking sputum, there is a certain risk of causing damage to the patient's respiratory mucosa, and when suctioning sputum through negative pressure, it will cause negative pressure scratches to the respiratory tract, and the suction efficiency is low
