Anti-infection protection device used for trachea cannula

Abstract

The invention provides an anti-infection protection device used for a trachea cannula. The anti-infection protection device is arranged on an air outlet pipe of the trachea cannula, and a bronchoscopebody of a bronchoscope penetrates through the trachea cannula; the device comprises a hollow casing and a closed air bag; one end of the casing is provided with a rubber plug, and the other end of the casing is hermetically connected with the air outlet pipe; a through hole is formed in the rubber plug; the diameter of the through hole is smaller than the outer diameter of the bronchoscope body of the bronchoscope; an opening is formed in the side wall of the casing; one end of the air bag hermetically communicates with the opening in the side wall of the casing; and the air bag is also provided with a drainage opening used for removing dirt in the air bag. Droplets generated in the trachea of a patient can enter the casing from a gap between the endoscope body and the trachea cannula, then enters the air bag from the opening in the side wall of the casing and is collected, and finally is collected into a drainage bottle from the drainage opening, so that the technical problem that the droplets are sprayed out of the air outlet pipe to pollute the surrounding environment is solved, thus being conducive to protecting the patient and a medical worker.

Description

technical field [0001] The invention relates to the technical field of tracheal intubation, in particular to an anti-infection protection device for tracheal intubation, especially for tracheal intubation treatment of infectious diseases such as novel coronavirus pneumonia, H1N1, H7N9, pneumonic plague, and tuberculosis. Background technique [0002] Such as figure 1 As shown, when performing a bronchoscopy on a patient, the bronchoscope needs to be inserted into the endotracheal tube. When the patient coughs, a large amount of sputum and droplets will be ejected from the endotracheal tube, and these sputum and droplets will flow from the trachea. Jet out from the gap formed by the intubation tube and the mirror body of the bronchoscope, such as figure 1 In the direction indicated by the arrow, these sputum and droplets will pollute the surrounding air, especially for patients with infectious diseases such as new coronary pneumonia, H1N1, H7N9, pneumonic plague, tuberculosi...

AI Technical Summary

Problems solved by technology

[0002] like figure 1 As shown, when performing a bronchoscopy on a patient, the bronchoscope needs to be inserted into the endotracheal tube. When the patient coughs, a large amount of sputum and droplets will be ejected from the endotracheal tube, and these sputum and droplets will flow from the trachea. Jet out from the gap formed by the intubation tube and the body of the bronchoscope, such as figure 1 In the direction indicated by the arrow, these sputum and droplets will pollute the surrounding air, especially for patients with infectious diseases such as new coronary pneumonia, H1N1, H7N9, pneumonic plague, tuberculosis, etc., causing infection hazards to patients and medical staff. There is a great risk of infection among personnel and surrounding personnel. At the same time, if these sputum and droplets fall on the hospital bed or floor, they will pollute the medical environment and pose a potential infection risk to the next wave of hospitalized patients and medical staff.
