DETAILED DESCRIPTION
[0029] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0030] Example: See Figure 1-3 The use of suction tubes can effectively clear sputum in the respiratory tract, reduce the risk of respiratory tract infection, and improve the patient's respiratory function. In order to achieve the cleaning of sputum in the patient's respiratory tract and avoid cross infection caused by contact between medical staff and the outside of the suction tube, this application discloses a disposable isolation suction tube, the specific working principle of which is as follows:
[0031] Before using the suction tube, you need to clean the patient's mouth and nasal cavity first, and then insert the tube into the patient's trachea or bronchus. The inner card 4 is mounted on the upper end of the first connecting joint 2 on the outside of the suction tube body 1, and the isolation film 6 is mounted on the inner card 4. The upper end of the isolation film 6 is fixed by the upper outer card 5, and the lower outer card 12 and the closed water bag ring 11 are respectively fixed on the outside of the lower end of the isolation film 6.
[0032] When using the suction tube, first, under the flexibility of the isolation film 6 itself and the action of the telescopic pleats 7, the isolation film 6 is stacked at the upper end. The inner card 4 and the upper outer card 5 are both conical in shape, so as to maintain a certain distance between the isolation film 6 and the suction tube body 1. If it is cylindrical, the isolation film 6 and the suction tube body 1 are easily fitted together, which is inconvenient to operate; the lower outer card 12 is an international standard connector, and when the suction tube body 1 needs to be connected to an endotracheal tube or a laryngeal mask, a detachable connection is made through it, and then the suction tube body 1 is inserted into the endotracheal tube or the laryngeal mask for use in suction. It can be used normally when only the suction tube is used, and there is no need to connect the endotracheal tube or the laryngeal mask.
[0033] After completing the preparation work, the medical staff connects the negative pressure suction device to the upper end of the negative pressure suction connector 3, and inserts the lower end of the sputum suction tube body 1 into the patient's trachea or bronchus. The lower part of the sputum suction tube body 1 is provided with a sputum suction port, and the negative pressure generated by the negative pressure suction device helps to extract the sputum in the patient's respiratory tract; when the suction force needs to be adjusted, the closing cap 10 at one end of the adjusting tube 8 is removed, and the suction force generated by the negative pressure suction device is adjusted by pressing the adjusting hole on the adjusting tube 8 with a finger. Pressing the adjusting hole has a large suction force, and releasing the adjusting hole has a small suction force; after the sputum suction is completed, the sputum suction tube body 1 is pulled out, and the isolation film 6 is loosened. A water injection port is provided on the closed water bag ring 11, and the water injection operation is performed in conjunction with the one-way valve. The isolation film 6 can be easily unfolded and covered with the sputum suction tube body 1 under the action of its own gravity of the closed water bag ring 11, which can effectively prevent medical staff from contacting the outside of the sputum suction tube, thereby avoiding the risk of cross infection. The isolation film 6 is a PVC film.
