Autogenous cutting casing pipe button capable of adjusting length and absorbing phlegm

Abstract

The invention discloses an autogenous cutting casing pipe button capable of adjusting length and absorbing phlegm. The autogenous cutting casing pipe button comprises an inner casing pipe, an outer casing pipe and a casing pipe cap, wherein the inner casing pipe is arranged in the cavity of the outer casing pipe and can move along the inner wall of the outer casing pipe; one end part of the inner casing pipe is connected with a fixed part; the fixed part is in shrinking state when being located in the cavity of the outer casing pipe; when the fixed part moves to the outside of the cavity of the outer casting pipe, the fixed part can be unfolded along the end surface of the outer casing pipe to form a plane and extend outside the outer edge of the annular wall of the outer casing pipe; the other end part of the inner casing pipe is provided with a boss; the boss and the inner part of the outer casing pipe can be clamped and fixed; one end part of the outer casing pipe is movably fit with the casing pipe cap; and the cap top of the casing pipe cap is provided with a through hole and a hole plug matched with the through hole. The autogenous cutting casing pipe button maintains an artificial airway to carry out airway management such as phlegm absorption, and maintains the function of the upper airway so as to be the same as a normal person, thereby greatly reducing the possibility of exogenous infection; and the autogenous cutting casing pipe button is beautiful in appearance, thus the life quality of a patient with a cut trachea is greatly improved.

Description

technical field [0001] The invention relates to a tracheotomy sleeve buckle with adjustable length and capable of sucking phlegm, belonging to the technical field of medical devices. Background technique [0002] Clinically, although some critically ill patients have been released from the ventilator after emergency treatment, they still need to retain an artificial airway (mainly a tracheostomy tube) to facilitate sputum suction, especially for patients with weak spontaneous cough and expectoration ability , such as chronic obstructive pulmonary disease, central neuromuscular disease, etc. The traditional tracheotomy tube directly exposes the patient's airway to the atmosphere, and the patient breathes air directly through the tracheotomy tube, which is prone to infection and dehydration of the airway. Moreover, due to the existence of the gas incision, air leakage is caused, and it is difficult for the patient to speak. These patients with chronic respiratory failure may...

AI Technical Summary

Problems solved by technology

In addition, for patients with poor lung function who are difficult to get off ventilator-assisted ventilation and have poor spontaneous coughing ability and need artificial airway, invasive ventilation is often used clinically. The opening of the airway will greatly increase the chance of infection. Invasive ventilation The high technical difficulty and risk of airway management also make it impossible for patients to leave the hospital and go home. Patients who depend on such ventilators will have to spend the rest of their lives in hospitals (mainly intensive care units), which greatly reduces the risk of death for patients. The quality of life is not conducive to the rational use of critical care medical resources
