Trachea cannula device suitable for bronchoscope operation emptysis rescue and difficult airways

Abstract

The invention relates to a trachea cannula device suitable for bronchoscope operation emptysis rescue and difficult airways. The trachea cannula device comprises a trachea cannula, a trachea cannula inner core and a guide wire, wherein the trachea cannula and the trachea cannula inner core have radians; a respirator pipeline interface is tightly inserted into the upper end of the trachea cannula; the trachea cannula inner core is sleeved into a trachea cannula cavity of a corresponding inner diameter; the lower section of the trachea cannula inner core extends out of the lower end of the trachea cannula; a hollow guide wire tube which is about 2.5 millimeters in diameter passes through the tube cavity of the cannula inner core; the lower end of the guide wire tube is connected and communicated with a guide wire head; and the lower end of the guide wire tube passes through an interface plug, and is communicated with the outside. The device disclosed by the invention can be used for completing tracheal intubation quickly and effectively for complicated airway massive haemorrhage during bronchoscope operation, and is suitable for an anaesthetist to perform endermic reverse tracheal intubation on difficult airways simultaneously. In an intubation process, operation is easy, convenient, rapid and accurate, and wounds are small. By means of trachea cannulas of different specifications, the device is suitable for infants to adults. The device is particularly suitable for being prepared for hospitals of all stages for performing bronchoscope operation and / or general anesthesia surgery.

Description

technical field [0001] The invention belongs to the field of trachea intubation medical equipment, in particular to a trachea intubation device suitable for bronchoscopic operation hemoptysis rescue and difficult airway. Background technique [0002] In clinical emergency, tracheal intubation can quickly establish an artificial airway and effectively solve the problem of ventilation for patients. Therefore, tracheal intubation is the most basic and effective clinical rescue method for suffocation. At present, there are many tracheal intubation methods that have been applied clinically, and clinicians can complete the tracheal intubation process for most patients under the direct vision of auxiliary equipment such as laryngoscope and bronchoscope. However, for a small number of patients with severe cervical spondylosis, temporomandibular joint ankylosis and other difficult airways, the traditional tracheal intubation method is quite difficult. In the clinical operation of br...

Problems solved by technology

However, once the bronchoscope exits the airway, the patient’s oronasopharynx is constantly gushing blood and extremely restless, which makes it difficult for the operator to quickly insert the bronchoscope into the airway again, so it is impossible to complete the endotracheal intubation guided by the bronchoscope; 2) The patient will soon have signs of suffocation due to hypoxia, restlessness, trismus, and a large amount of blood and blood clots will accumulate in the mouth, nose, pharynx, and airway. The tube is also very difficult; 3) The function of the respiratory system is important, and the space of the bronchial tree is limited. Once massive hemoptysis occurs and the bleeding volume is greater than 50ml, the coagulated blood clot will completely block the airway soon. Therefore, it is necessary to race against time to establish an effective artificial airway. However, it takes too long to open the airway by surgical operations such as tracheotomy, and it has no practical clinical significance.

At present, there is no simple, effective and easy-to-operate clinical tracheal intubation device
