Airway management series device used after tracheotomy

Abstract

The invention relates to the field of tracheal cannula nursing supplies. An airway management series device used after tracheotomy comprises an airway cannula used after tracheotomy; the airway cannula comprises an outer sleeve and a matched inner sleeve, and also comprises a humidifying structure, wherein the humidifying structure comprises an airway joint, a threaded extension pipe and an atomizing tank which are sequentially connected; the airway joint is detachably connected with the outer end of the inner sleeve; a gas exchange hole is formed in the airway joint; a rubber plug for temporarily injecting liquid medicines is arranged in one side of the top of the atomizing tank; a medicine adding hole for continuously infusing the liquid medicines is arranged in the other side of the topof the atomizing tank; an oxygen conduit interface is arranged on one side of the middle part of the atomizing tank; the airway cannula also comprises an anti-reverse flow valve, wherein the rear endof the inner sleeve is detachably connected with the anti-reverse flow valve; the anti-reverse flow valve comprises a valve body and an anti-reverse flow limiting piece arranged in the valve body; the rear side of the valve body is in threaded connection with a sealing plug. The airway joint and the inner cannula are detachable, so that the problem that an atomizing device on the market at present is not matched with a tracheal intubation joint is solved.

Description

technical field [0001] The invention relates to the field of tracheal tube care products, in particular to an airway management device after tracheotomy. Background technique [0002] Tracheotomy is an emergency technique for rescuing critically ill patients, and it can improve dyspnea caused by various reasons after operation. It is an operation in which the front wall of the trachea in the neck is cut open, and an endotracheal tube of appropriate size is inserted into the trachea through the incision, so that the patient can breathe directly through the endotracheal tube. [0003] The purpose of tracheotomy is to prevent or quickly relieve airway obstruction, ensure unobstructed airway, ensure effective ventilation, and improve breathing. [0004] After the tracheotomy, a dedicated post-tracheotomy tube must be inserted into the patient's trachea. A conventional post-tracheostomy tube includes an outer tube and an inner tube inserted into the outer tube, the outer tube h...

Problems solved by technology

When clinical nurses are nebulizing patients, there are the following problems when using the mask method for aerosol inhalation: first, a large amount of medicinal liquid cannot reach the lungs to produce curative effect, and second, it causes a large amount of medicinal liquid to be wasted

In autumn and winter, some patients have viscous sputum and easy to produce sputum scabs, which require continuous humidification. Currently, existing devices require nurses to administer medication frequently, which also increases the workload of clinical nursing.

[0007] In addition, for the treatment of patients' sputum, the existing method is often to connect a collection bag for collecting sputum on the back side of the inner cannula. However, since the inner cannula does not have an anti-reflux structure, once the sputum goes backward, Risk of severe lung infection and related complications in patients

Moreover, when the patient coughs, the sputum will be sprayed out from the endotracheal intubation port with a large impact force, which is likely to cause long-distance pollution, and the pollution covers a large area
