Problems solved by technology

For peripheral lesions, local bronchial occlusion or the Chartis system can be used to observe the air leakage or the Chartis system to find the location of the fistula. However, the operation of local occlusion observation is very cumbersome and time-consuming; Expensive and poorly popularized, so the former is cumbersome to operate, and the latter is expensive and poorly popularized

Embodiment 1

[0010] see figure 1 , figure 2 , a device for detecting tracheobronchial fistula, mainly composed of a detection catheter 1, a balloon catheter 2, a blocking balloon 3, and a three-way interface 8, the detection catheter 1 tube body is a hollow flexible tube body, and the detection catheter 1 The tail end is connected to the three-way interface 8, the end of the three-way interface is a screw joint 4, which can be connected to a carbon dioxide monitor, and the upper end interface 5 can be connected to a syringe, which is used to dredge the detection catheter 1 blocked by airway mucus when necessary, and the head end interface 6. Connect to the detection catheter 1. The side wall of the head end of the detection catheter 1 is provided with a side port 9 to reduce the situation that the detection catheter is completely blocked by airway secretions. The balloon catheter 2 is the outer tube of the detection catheter 1. The blocking balloon 3 is integrated with the balloon cathet...

Embodiment 2

[0014] The invention utilizes the difference of the carbon dioxide concentration and waveform inside and outside the lungs to quickly and accurately detect the position of the tracheobronchial fistula and determine whether there is a traffic ventilation bronchus.

[0015] In actual operation, first connect the screw interface 4 of the three-way interface 8 to the carbon dioxide measurement module of the monitor, connect the upper end interface 5 to the syringe, and perform zero calibration, and then pass the sampling end of the measuring catheter through the working channel of the flexible bronchoscope or hard The outer tube of the bronchoscope is passed into the lungs. For the central fistula, combined with visual observation, detect the suspected fistula area. When the catheter is in the normal area, the waveform can be seen, but when the catheter tip enters the fistula, the visible carbon dioxide waveform disappears. For the peripheral fistula, reach the suspicious lobe bro...

Abstract

The invention provides a tracheal bronchus orificium fistula detecting device which mainly comprises a detection catheter, a balloon catheter, an occlusion balloon and a three-way connector. The three-way connector is connected with the tail end of the detection catheter and is connected with a carbon dioxide monitoring instrument, a connected syringe and the detection catheter, side openings are formed in the side walls of the head end of the detection catheter, the balloon catheter is used as an outer cannula for the detection catheter, a far end of the balloon catheter is connected with the occlusion balloon, and a hose connector at the tail end of the balloon catheter is communicated with the syringe and is used for blowing the balloon, so that local airways can be occluded. The tracheal bronchus orificium fistula detecting device has the advantages that the locations of orificium fistulae of tracheal bronchi can be accurately judged by the aid of difference of internal and external carbon dioxide concentration and measurement waveforms, and whether communication breather bronchi are available or not can be judged; the tracheal bronchus orificium fistula detecting device can be easily and feasibly operated and is excellent in peripheral bronchopleural fistula sensitivity, and the diagnosis rate and the cure rate of the orificium fistulae of the tracheal bronchi can be obviously increased; the tracheal bronchus orificium fistula detecting device is reasonable in design, simple in structure, convenient to operate, low in cost and high in efficiency.

Description

technical field [0001] The invention belongs to small medical instruments and relates to a device for detecting tracheobronchial fistula. Background technique [0002] At present, severe pulmonary infection and neoplastic diseases such as esophageal cancer, lung cancer, and gastric cancer have a high incidence. At the same time, with the continuous improvement of diagnosis and treatment technology, the number of patients with tracheal intubation and tracheotomy has also increased significantly. The incidence of tracheoesophageal fistula, bronchopleural fistula, bronchogastric fistula, and surgical stump fistula, which are motivated by disease and iatrogenic factors, also increased. At present, interventional therapy under bronchoscopic treatment is effective in the treatment of various fistulas, but the difficulty in diagnosis and treatment lies in determining the location of the fistula. At present, the main method for tracheobronchial fistula is to find the fistula throu...
