Problems solved by technology

Non-invasive positive pressure ventilation is a symptomatic support method to improve ventilation and reduce hypoxia. However, most patients tolerate it very poorly, leading to treatment failure, and the long-term effect of surgical methods is not satisfactory. There is no effective treatment for this syndrome

Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] A specific embodiment of a sleeve tube for tracheotomy of the present invention, such as figure 1 and figure 2 As shown, the cannula for tracheotomy includes an outer tube 1 and an inner tube 2 that movably cooperates with the outer tube 1 . like Figure 3 to Figure 6 As shown, the outer tube 1 in this embodiment includes an outer tube body 6 and an outer tube flange 3, defining the end of the outer tube 1 for insertion into the trachea 11 as the inner end, and the end exposed outside the trachea 11 as the outer end , then the outer tube flange 3 is arranged at the outer end orifice of the outer tube 1 . When in use, the inner end of the outer tube 1 is inserted into the trachea 11 from the tracheostomy, and the insertion depth of the outer tube 1 into the trachea 11 is limited by the blocking fit between the outer tube flange 3 and the outsid...

Abstract

The invention relates to a sleeve for a tracheotomy. The sleeve for the tracheotomy comprises an external tube for inserting into a trachea from the tracheostomy, and an internal tube for inserting the external tube and extending the trachea, the internal tube is movably matched with the external tube, thus the internal tube can be inserted into the external tube when a patient sleeps, the external tube is pulled out when the patient is awake, it is defined that the end of the external tube for inserting into the trachea is the inner end, the end exposed outside the trachea is the outer end, an external tube stopping part for being stopped and matched with the outer part of the neck of the patient and fixed to the neck of the patient to limit the insertion depth of the external tube into the trachea is arranged at an orifice of the outer end of the external tube, an internal tube stopping part for being stopped and matched with the external tube stopping part and fixed to the neck of the patient to limit the insertion depth of the internal tube into the trachea is arranged on the internal tube, the length of the internal tube for inserting into the trachea is greater than that of the external tube for inserting into the trachea, and thus the sleeve is suitable for the patient to live with the tube for a long time.

Description

technical field [0001] The invention relates to a sleeve tube for tracheotomy. Background technique [0002] Currently, the incidence of obstructive sleep apnea-hypopnea syndrome is relatively high in patients, and this syndrome is an independent risk factor for cardiovascular and cerebrovascular diseases. Non-invasive positive pressure ventilation is a symptomatic support method to improve ventilation and reduce hypoxia. However, most patients tolerate it very poorly, leading to treatment failure, and the long-term effect of surgical methods is not satisfactory. There is no effective treatment for this syndrome . In clinical practice, it is found that patients with tracheostomy tubes have no ventilation obstruction. Therefore, a cannula can be designed to be placed in the patient's tracheostomy, combined with daily care, so that the patient can survive with the tube, thereby improving ventilation and reducing The occurrence of cardiovascular and cerebrovascular complicati...
