Description

an endotracheal tube

technical field

The invention relates to the technical field of medical devices, in particular to a tracheal intubation tube.

Background technique

Endotracheal intubation is an important medical device in the process of cardiopulmonary resuscitation and the rescue of critically ill patients with respiratory dysfunction. The existing endotracheal intubation includes a catheter and an endotracheal aspirator. The catheter is equipped with a positioning airbag; when working, First, insert the catheter into the lungs of the patient from the incision in the patient's neck or from the mouth and nose, then inflate the positioning airbag into the patient's airway for positioning, then connect the inlet connector of the catheter to the ventilator, and perform manual ventilation on the patient. Breathing, during the process of artificial respiration, when the catheter is inserted into the incision of the patient's mouth, nose or neck, the patient will easily produce secretions such as mouth and nose, most of these secretions flow into the catheter and are sucked into the tube The device is sucked out in time to ensure the smoothness of the airway. However, in practical applications, a small amount of secretions will flow along the outer wall of the catheter into the space surrounded by the airway, the catheter and the positioning air bag. Cutting the opening will cause infection of the patient's lungs or the incision, and cause danger to the patient's life.

Contents of the invention

The purpose of the present invention is to provide a tracheal intubation to solve the problem of untimely cleaning of secretions in the tracheal intubation in the prior art.

To achieve the above object, the technical scheme adopted in the present invention is as follows:

A tracheal intubation tube, comprising a cannula body, on which a column plate is slidably sleeved, and a push rod is connected to the column plate, and the end of the push rod away from the column plate extends along the intubation body, and a cavity is opened in the column plate , a plurality of through holes connecting the cavity and the outside world are opened on the column plate, a conduit is connected to the cavity, a cleaning device is connected to the conduit, an adsorption tube is wound around the column plate, and a plurality of adsorption holes are opened on the adsorption tube. The adsorption tube is connected with a negative pressure device.

The principle of the present invention: when in use, insert the end of the cannula body with the positioning air bag into the human trachea according to relevant operations, provide physiological saline to the catheter through the cleaning device, and the saline flows into the column plate through the catheter, and finally passes through the column plate Dilute and clean the secretions by spilling them through the through holes on the top, and then start the negative pressure device to suck the secretions out from the adsorption holes and adsorption tubes through negative pressure, so as to realize timely cleaning. During the process, the push rod can be pulled back and forth, and the push rod can be used to drive the column plate to slide back and forth, and the column plate will drive the adsorption tube to slide back and forth, so as to achieve comprehensive cleaning and avoid secretion adhesion and accumulation.

Compared with the prior art, the present invention has the beneficial effect: setting the column plate, firstly, the injected physiological saline can be collected by the column plate and then quickly dispersed to achieve the effect of homogenization, and the secretion can be fully diluted and cleaned, It is conducive to subsequent adsorption to achieve the effect of completely removing secretions; secondly, a column plate with sliding connection is set, and by using its sliding, a wide range of secretions can be cleaned and the adsorption can be completed, which can effectively remove the generated secretions. Cleaning; Finally, during the sliding process, the column plate can also scrape off the secretions adhering to the outer wall of the endotracheal tube, further achieving the effect of cleaning the secretions.

Further, the adsorption tube is spirally wound on the outer wall of the cannula body. In order to better absorb the secretions and avoid the secretions from adhering to the outer wall of the cannula body.

Further, the adsorption end of the adsorption tube is fixed on the column plate, and the adsorption holes are arranged close to the column plate. When the column plate slides, the adsorption end of the adsorption tube can slide with the column plate, so that the secretions diluted and cleaned by the column plate can be adsorbed in real time, and the adsorption efficiency can be improved.

Further, the edge of the column is arc-shaped. In order to reduce the damage to the inner wall of the trachea of the human body during the sliding process of the column disc.

Further, the push rod is arranged close to the cannula body. The space occupied by the tracheal intubation is reduced, the structure is more compact, and the pressure on the human trachea is reduced.

Further, a positioning air bag is fixedly sleeved on the outer wall of the cannula body, and the positioning air bag is connected with an inflation device. The positioning airbag is set to fix the tracheal intubation in the human trachea, that is, the positioning airbag is inflated to offset the human trachea, reducing the range of motion of the tracheal intubation and achieving the effect of positioning.

Further, the positioning airbag is in the shape of an ellipsoid. It is set as an ellipsoid and when the positioning airbag is inflated, its length is offset against the inner wall of the human trachea, and its short end is in contact with the inner wall of the human trachea, which can reduce the external force of the human trachea, because the patient may use the trachea for a long time. tube, if the inner wall of the human trachea is in a state of compression for a long time, it is easy to cause the human tracheal tissue to lose its elasticity, and the setting of the present application can reduce this risk.

Further, the inner wall of the cannula body is provided with several cilium-like structures obliquely upward along the inner wall of the cannula. A cilia-like structure is set on the inner wall of the tracheal intubation, which mimics the cilia on the inner wall of the human trachea, and uses the cilia-like structure to form upward oblique folds to attach water vapor and sputum, preventing water vapor and sputum from slipping into the trachea and causing tracheal occlusion.

Further, the column plate is provided with a pressure sensor, the pressure sensor is electrically connected to a controller, and the controller is electrically connected to the negative pressure device. A pressure sensor is set to detect the pressure during the adsorption process to prevent damage to the human trachea caused by excessive adsorption pressure.

Further, a visual camera is provided on the column plate. It is convenient to observe the insertion of the endotracheal tube inside the human body, and can avoid damage to human tissues caused by blind insertion.
