Description

Tracheal catheter with dredging function

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an endotracheal tube with a dredging function.

Background

Tracheal tubes are medical devices that are inserted into the trachea or bronchi of a patient, creating a temporary artificial respiratory pathway for the patient, particularly a patient who cannot breathe spontaneously. The cannula body is generally made of high polymer materials, and steel wire coils are embedded in the cannula body so as to improve radial strength and axial softness. Clinically, tracheal tubes are often blocked by sputum, sputum scab, gastrointestinal fluids, blood, foreign matter, and the like. In order to ensure the life safety of the patient as much as possible, besides the laying and preventive measures in the earlier stage, the condition of the patient needs to be monitored at any time so as to ensure the first time for treatment and avoid danger.

When the tracheal catheter is blocked, the existing emergency treatment scheme comprises immediately pumping out the gas in the air sac, dripping distilled water or 1.5% sodium bicarbonate into the air passage, expanding the lung and sucking phlegm, and sucking the blocked sputum crust as soon as possible; the trachea cannula guide wire is inserted into the trachea cannula to poke out foreign matters such as sputum scab and the like, so that the blockage is removed. Only when the situation is critical, the trachea cannula or the tracheotomy catheter can be pulled out, the airway is opened, the balloon assists in breathing, and the cannula is re-inserted.

When the tracheal catheter is connected into the patient, a relatively closed pipeline is formed, and if the foreign matter is sucked directly, the foreign matter is not sucked by the pressure difference, and the foreign matter is difficult to suck. The foreign matter poking-out time through the guide wire is longer, and the treatment time and efficiency are delayed. Therefore, in order to quickly dredge the tracheal catheter, an tracheal catheter with a dredging function is currently proposed.
