Description

Isolation mask for tracheal catheter tube drawing

Technical Field

The utility model relates to a tracheal catheter extubation isolation face guard relates to medical instrument field.

Background

The new coronavirus pneumonia (COVID-19) protocol (seventh edition of pilot) indicated that transmission via respiratory droplets and intimate contact is the major transmission route for the new coronavirus, and that there is a potential for transmission via aerosols when exposed to high concentrations of aerosols for extended periods of time in a relatively confined environment. At present, no specific medicine for treating COVID-19 exists. Invasive mechanical ventilation is one of the important supportive treatments for patients with severe, especially critically ill COVID-19. Some patients suspected or diagnosed with COVID-19 have to be treated by surgery for the surgical disease. After the general anesthesia operation is finished and the tracheal catheter is pulled out, the medical staff has extremely high exposure and infection risks. This risk comes primarily from two aspects, on the one hand, when such patients remove the tracheal tube, the cough reflex expels the viral secretions deep in the trachea through the respiratory tract; on the other hand, when the tracheal catheter is pulled out, the sputum or secretion with virus adhered on the tracheal catheter easily pollutes the surrounding environment. Therefore, how to reduce the outward discharge of secretion when a patient coughs and reduce the pollution of surrounding work areas after the sputum or secretion catheter adhered with a large amount of viruses is pulled out by changing an air inlet management tool is very important for the safety control of first-line medical staff in the department of anesthesia, the department of respiration, the department of critical care, the department of emergency treatment, the department of infection and the like. Currently, no such isolation mask for endotracheal intubation in patients with such specific infections has been clinically available.

Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1 to 6, the tracheal catheter extubation isolation mask comprises an oral nasal mask 2 with a bandage 1, wherein the front part of the oral nasal mask is provided with a large hole 3, an inhalation hole 4 and an exhalation hole 5, the large hole is connected with a plastic sleeve 6 with a terminal closed to be a blind end, and both the inhalation hole and the exhalation hole are provided with an artificial nose filter 7.

The embodiment of the utility model provides an in, the oronasal face guard is triangle-shaped, just in time covers nasal part and oral area, does not have the influence to eyes, and the oronasal face guard is close to the nasal root and upwards is connected with a T type plastic support 8 and hugs closely in the forehead middle part to bandage through the connection of the left and right sides encircles and is fixed in the head, and the oronasal face guard is close to the left and right sides of oral area and also has the bandage and encircle and be fixed in back neck.

In the embodiment of the present invention, the rear end face of the oral nasal mask has an air bag 9 adapted to the shape thereof.

In the embodiment of the utility model, the bandage is the elasticity strap.
