Description

Novel trachea cannula
Technical Field
The utility model relates to the field of medical supplies, in particular to a novel trachea cannula.
Background
In the emergency rescue process of a critically ill patient, in order to avoid the situation that the trachea of the patient is blocked by a blocking object so as to cause life crisis, the tracheal catheter is inserted through the mouth cavity, which is the most common establishment mode of an artificial airway, for example, in the domestic known clinical cardiopulmonary resuscitation, one of the most common rescue measures is that a breathing tube is inserted into the trachea of the patient through the mouth cavity so as to enhance the auxiliary breathing for the patient.
But in the process of inflating the cuff, the traditional single air outlet hole has low air outlet quantity and slightly long inflation time of the cuff; meanwhile, the sealing between the breathing machine interface and the tube body and between the inflation tube and the tube body is lacked, and the whole air tightness is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel trachea cannula which can be inflated rapidly.
The purpose of the utility model is realized like this: a novel trachea cannula comprises a cannula body and a cuff inflating device connected with the cannula body; the pipe body is of a double-layer structure; an inclined tip is arranged at the front end of the tube body, and Murphy outlets are arranged on two sides of the tip; a double cuff is arranged behind the tip end and connected with the tube body, and an air outlet hole is formed in the tube wall at the joint of the double cuff and the tube body; the rear part of the tube body is connected with an inflation tube, the inflation tube is arranged inside the double-layer tube body and is connected with the air outlet hole, the rear part of the inflation tube is provided with an indicating balloon, and the tail end of the inflation tube is provided with a one-way valve; the rear end of the tube body is provided with an expiratory machine interface.
Compared with the prior art, the utility model discloses an useful part lies in: because the air outlet holes are respectively arranged in the double cuffs, the double cuffs can simultaneously intake air, and compared with the traditional single air outlet hole, the integral air inflation time is shorter and the air inflation speed is higher; the anti-cracking rubber bag is arranged at the joint of the inflation tube and the tube body, so that the joint is not easy to break, and the use is more convenient; the wavy sealing parts are arranged on the inner side of the rear end of the pipe body and the outer part of the connector, so that the pipe body and the connector are connected more tightly, and the air leakage condition is avoided; the tip is covered with metal particles inside, so that the tip can be accurately positioned by X-rays.
As the utility model discloses a preferred scheme, body rear end inboard, interface outside are provided with wavy sealing, the interface is connected with the body normal running fit.
As a further preferred proposal of the utility model, the tube body is carved with scales inserted into the depth of the human body.
As a further preferred proposal of the utility model, the number of the air outlet holes is two, and the air outlet holes are respectively arranged in the double cuffs.
As a further preferred scheme of the utility model, be provided with the crack control rubber package between gas tube and the body.
As a further preferable aspect of the present invention, the tip is internally covered with metal particles.
