Sputum suction catheter

Abstract

The invention discloses a sputum suction catheter, which comprises a negative pressure ball and a sputum suction hose pipe, wherein the sputum suction hose pipe is connected with the lower end of the negative pressure ball and is in seamless sealing connection with the negative pressure ball, the upper end of the negative pressure ball is provided with a one-way valve I, one end, near the negative pressure ball, of the sputum suction hose pipe is provided with a one-way valve II, and the tail end, away from the negative pressure ball, of the sputum suction hose pipe is provided with a sputum suction hole. The sputum suction catheter has the beneficial effect that the suction pressure is provided through the negative pressure ball, and the sputum suction hose pipe is made of PVC (polyvinyl chloride) material, so the sputum suction procedure is greatly simplified, the problems of sterilization and disinfection of the sputum suction process are solved, the problem of damage to mucosa of an oral cavity and a respiratory track of a patient is effectively solved, the working reliability and safety of the sputum suction catheter are improved, and the sputum suction catheter is suitable for being popularized within a larger range.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a sputum suction tube. Background technique [0002] The sputum suction tube is a medical device used clinically to remove sputum or viscous secretions in the patient's respiratory tract. Its purpose is to remove the secretions in the patient's respiratory tract and keep the patient's respiratory tract unobstructed. In the prior art, the sputum suction tube is generally used in connection with the sputum suction device, and the suction pressure during sputum suction is too high during use, which often causes damage to the patient's oral cavity and respiratory tract mucosa. Moreover, the steps during sputum suction are complicated and cumbersome, and the aseptic operation and complete disinfection cannot be guaranteed, which can easily cause secondary infection of the patient's respiratory tract and increase the incidence of nosocomial infection. [0003] In addition, the t...

Problems solved by technology

[0005] The purpose of the present invention is to provide a sputum suction tube to overcome that the sputum suction tube in the prior art is easy to cause damage to the patient's respiratory tract mucosa and oral cavity during use, and cannot guarantee aseptic operation and complete disinfection during use. The operation steps are complicated during use and it is easy to cause pollution of the surrounding environment and problems such as atelectasis and hypoxemia in patients
