Sputum suction catheter

Abstract

The invention discloses a sputum suction catheter. The sputum suction catheter comprises a hollow catheter body, wherein a plurality of sputum suction ports are formed in the front end of the catheter body; a sputum suction catheter connector is connected to the rear end of the catheter body; brush hair is arranged in the region, close to the front end, of the catheter body, and is arranged in an inclined manner; and one end of the brush hair is fixed on the outer wall of the catheter body, and the other end of the brush hair extends toward the rear end of the catheter body in an inclined manner. Sputum suction treatment is carried out by using the sputum suction catheter, sputum scab attached on the inner wall of the catheter can be completely cleaned in the sputum suction operation process without changing the existing sputum suction operation, operation is simple, and the sputum scab cleaning effect is good. Specifically, when the sputum suction catheter is inserted in a trachea cannula, the brush hair is drawn toward the catheter body and is in a drawn state, and the difficulty of inserting the sputum suction catheter into the trachea cannula cannot be increased; and when the sputum suction catheter is rotated to leave the trachea cannula, the brush hair is rotated together with the sputum suction catheter body, the sputum scab gathered on the inner wall of the trachea cannula can be peeled; and the peeled sputum scab can be sucked out from the sputum suction ports under the action of negative pressure adsorption.

Description

technical field [0001] The invention relates to a sputum suction tube, which belongs to the field of medical devices. Background technique [0002] Severely ill patients are bedridden for a long time, and most of the patients have tracheal intubation, so the sputum cannot be coughed up by themselves; and the sputum remains in the mouth and between the teeth, it is easy to breed bacteria, produce peculiar smell or even erosion, and cause lower respiratory tract infection. Sputum suction and oral care of critically ill patients are very important. However, in the process of using the tracheal intubation, sputum tends to adhere to the inner wall of the tracheal intubation, thereby forming a sputum scab. Simply relying on the negative pressure adsorption of the disposable sputum suction tube cannot completely remove the sputum scab from the inner wall of the tracheal intubation tube, and the long-term accumulation of the sputum scab can easily block the tracheal intubation, thu...

AI Technical Summary

Problems solved by technology

However, frequent suction of sputum needs to frequently cut off the access between the ventilator and the endotracheal tube, which will have a certain impact on the patient's breathing

Relying on the flushing effect can easily cause damage to the patient's trachea, and the effect of removing phlegm scab is not satisfactory.

For this reason, in order to ensure the normal breathing of the patient, the tracheal intubation needs to be replaced irregularly, and every time the tracheal intubation is replaced, the trachea will inevitably be damaged again.
