Conversion type jet ventilation catheter

Abstract

The invention relates to a conversion type jet ventilation catheter, which comprises a ventilation main catheter, a carbon dioxide detection branch catheter, a cuff inflation branch catheter and a main catheter cuff, openings are formed in the inner walls of two sides close to the upper end opening of the ventilation main catheter; the carbon dioxide detection branch catheter and the cuff inflation branch catheter are arranged in the openings, a main catheter cuff is arranged on the ventilation main catheter and located on the lower half section of the ventilation main catheter, the radius ofthe main catheter cuff is larger than the inner diameter of the ventilation main catheter, and the lower end opening of the ventilation main catheter is arranged in an inclined opening shape. The invention has the advantages that: the conversion type jet ventilation catheter can assist mouth and nose ventilation and keep the respiratory tract unobstructed, can achieve operation of different branchcatheters at the same time without interference to one another, the mechanical pressure ventilation mode and the jet ventilation catheter can be converted timely so as to facilitate timely conversionof different ventilation modes, and favorable conditions are provided for taking out foreign matters in the airway.

Description

technical field [0001] The invention relates to the field of clinical auxiliary technology, in particular to a conversion jet ventilation catheter. Background technique [0002] Airway foreign body is a potentially life-threatening emergency, including upper airway foreign body and lower airway foreign body. Patients will have symptoms such as coughing and distress suffocation, which are common in children under 5 years old. High-frequency jet ventilation through the rigid bronchoscope side port is the most commonly used ventilation method for airway foreign body removal. It is mainly used for main trachea foreign body removal, and can reduce the risk of asphyxia caused by foreign body displacement during tracheal intubation. However, there are some defects in the application of this ventilation method in the removal of bronchial foreign bodies. The main problem of airway foreign body removal is that most of the airway is occupied by surgical operation, and the airway is n...

Problems solved by technology

[0005] In the above two devices, the monitoring catheter, the oxygen suction tube and the sputum suction tube share the same lumen, and cannot be operated at the same time, and there is also a lack of marks and scales for medical staff to refer to, so it is impossible to judge the depth of the inserted ventilation tube. Therefore, it cannot meet the needs of users

[0006] So to sum up, there is an urgent need for a convertible jet ventilation catheter that can assist mouth and nose ventilation, keep the airway unobstructed, and can operate different branches at the same time without interfering with each other, and is suitable for jet ventilation of children with foreign bodies in the airway. And about this new type conversion jet ventilation catheter, there is no report yet
