Device for removing residues on balloon of tracheal cannula of patient

Abstract

The invention discloses a device for removing residues on the balloon of a tracheal cannula of a patient. The device provided by the invention is characterized in that the device contains the tracheal cannula (1) with the balloon, a simply respirator (2) and a syringe (3); the tracheal cannula with the balloon consists of a duct (1-1), the balloon (1-2) and a gas-filled tube (1-3); the duct contains two free-ends, one end is an inject end, the other end is an air supply end; the gas-filled tube is used to fill the balloon, one end of the gas-filled tube is connected with the balloon, the other end is a free-end; the charging end of the duct is connected with the simply respirator; and the free-end of the gas-filled tube is connected with the syringe. The device provided by the invention adopts the air impact method to remove the residues on the balloon, uses the simply respirator to help for ventilation and removal and does not need the special artificial airway, thus the device can effectively remove the residues on the balloon, and has low side effect and medical cost, wide application area and practical value.

Description

technical field [0001] The invention relates to a device for removing the stagnant matter on the air bag of patients with tracheal intubation. Background technique [0002] In the intensive care unit (ICU), patients often need to use a ventilator, which supplies air to the patient through a tracheal tube. In patients with endotracheal intubation, the closure of the glottis and epiglottis is blocked, and it is difficult to prevent oronasal secretions from flowing into the airway along the tube. A large number of bacteria colonize and multiply. When the patient coughs hard or the air bag is deflated, some secretions flow down, causing the patient to cough and increase the risk of infection. At present, a number of studies have confirmed the correlation between the retention on the air sac (subglottic secretion) and premature ventilator-associated pneumonia (VAP). Increase, the fatality rate increases, especially for immunosuppressed patients, once VAP occurs, the fatality ra...

Problems solved by technology

In patients with endotracheal intubation, the closure of the glottis and epiglottis is blocked, and it is difficult to prevent oronasal secretions from flowing into the airway along the tube. A large number of bacteria colonize and multiply. When the patient coughs forcefully or the air bag is deflated, some secretions flow down, causing the patient to cough and increase the risk of infection

At present, a number of studies have confirmed the correlation between the retention on the air sac (subglottic secretion) and premature ventilator-associated pneumonia (VAP). Increase, the fatality rate increases, especially for immunosuppressed patients, once VAP occurs, the fatality rate is as high as 100%
