Indwelling closed type safe plastic tracheostomy tube device

Abstract

An indwelling closed type safe plastic tracheostomy tube device comprises a flexible tracheostomy tube, and an inner core is arranged in an inner cavity of the flexible tracheostomy tube; the flexible tracheostomy tube is inserted into a subcutaneous tunnel main body structure, the subcutaneous tunnel main body structure comprises a tube body arranged outside the flexible tracheostomy tube in a sleeving mode, a pair of fixing wings attached to the neck of a human body is symmetrically arranged at the upper end of the tube body, and a butterfly wing fixing device is arranged at the lower end of the tube body and comprises folding rods, a pull ring and traction ropes; the lower ends of the folding rods are connected with a pull ring, and the pull ring is arranged outside the flexible tracheostomy tube in a sleeving mode. The two traction ropes are symmetrically connected to the pull ring and upwards penetrate through the fixing wings; the traction ropes are pulled upwards, the pull ring is lifted upwards to enable the two folding rods to be unfolded outwards to form a butterfly wing-shaped buckle structure, and the interior of the subcutaneous tunnel body structure is fixed. A tunnel from the subcutaneous part of the neck to the tracheal cavity is reserved for people who pull out the tracheostomy tube conventionally, the safety of a patient after tube pulling is greatly guaranteed, and the indwelling closed type safe plastic tracheostomy tube device has the advantages of being simple, convenient to use, easy to operate and the like.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an indwelling and closed safety plastic gas cutting sleeve device. Background technique [0002] In clinical practice, some patients received tracheotomy and indwelling tracheostomy tube for various reasons. These patients may need to remove the tracheotomy cannula due to the improvement of their condition and return to the normal state of oral and nasal ventilation. Long-term indwelling tracheostomy tubes can cause tracheal stenosis after tracheostomy for various reasons, such as glottic or subglottic edema, local scar stenosis, local granulation, tracheal collapse caused by cartilage damage, local ulceration or necrosis, etc. A small proportion of patients with tracheostomy had tracheal stenosis that was so insidious that it was difficult to detect before extubation. Related reports suggest that factors such as obesity, unresponsiveness, and communication barriers...
