Determination of the outer diameter of the bronchial segment
The catheter bronchial segment is measured by winding an inelastic wire on the bronchial segment of the tracheobronchial tube and measuring the length of the wire. Outer diameter (OD). This method measures the equivalent circle diameter (see A.3.3). A.2 Instrument
A.2.1 Inelastic filaments of sufficient length to be entangled five times at the midpoint of the bronchial cuff (see Figure 9 of Figure 1) after deflation of the bronchial segment. A.2.2 Apparatus for measuring the length of inelastic threads (A.2.1) in millimeters. A.3 steps
A.3.1 On the bronchial segment of the catheter, use the inelastic silk thread (A.2.1) to surround the midpoint of the bronchial cuff after deflation (see Note 9 in Figure 1). Wrap five turns around the gap.
A.3.2 Measure the length of the inelastic wire in millimeters.
A.3.3 The outer diameter (OD) is calculated by dividing the length of the wire by 5π (ie. 5 × 3.14 = 15.7). A.4 result representation
The results measured in accordance with A.3.3 are expressed in millimeters, retained to one decimal place, and uploaded to the nearest 0.5 mm. Example. 9.1mm is expressed as 9.5mm
9.6mm is expressed as 10.0mm
13.1mm is expressed as 13.5mm
Note. The diameter is expressed as a larger 0.5 mm to ensure that a catheter that is thinner than the bronchus is selected. Appendix B
Effective inner diameter measurement method
The effective inner diameter (ID) was determined by passing a series of measuring beads through the bronchial segments of the catheter and the lumen of the tracheal segment. Measuring the diameter of the bead The table can pass through the largest diameter of the bronchoscope of the tracheal and bronchial lumen of the tracheobronchial duct. This trial was performed because the bronchoscope was Flexibility is limited when passing through a curved lumen, and the cross-section of the lumen of the catheter may be non-circular to limit measurement (see Figure 1). B.2 Instruments
B.2.1 Three polished cylindrical measuring beads (see Figure B.1) with the same diameter D and a spherical end with a total length of twice the diameter (2D). diameter The accuracy should be ±0.01mm and the length accuracy should be ±0.1mm. The end radius should be the nominal radius, and the knot length between each measuring bead should be It is 1mm~2mm. To determine the maximum bronchoscope diameter, multiple sets of measuring beads should be used with a diameter of 0.2 mm. If the manufacturer The maximum bronchoscope diameter is given and can be verified using a set of measuring beads. The unit is mm
1 --- knotted;
2 --- measuring beads;
D---Measure the bead diameter.
Figure B.1 Schematic diagram of a set of cylindrical measuring beads
B.2.2 Heavy object, mass 100g, connected to the measuring bead (B.2.1), one end is a wire long enough to pull the measuring beads through the catheter. B.3 steps
B.3.1 Hold the tracheobronchial tube vertically so that the filament thread passes through the lumen of the bronchial segment of the catheter. B.3.2 Attach the weight to the end of the wire.
B.3.3 Pass the measuring bead from the machine end of the bronchial lumen so that the weight pulls the measuring bead through the catheter. The lumen can be lubricated with water or water The agent is lubricated to help measure the passage of the beads.
B.3.4 For the lumen of the tracheal section, repeat steps B.3.1 to B.3.3. B.4 Results representation
The result is expressed in millimeters, retained to one decimal place, and rounded down to the nearest 0.2 mm measured in B.3. Example. 2.1mm is expressed as 2.0mm
3.7mm is expressed as 3.6mm
4.8mm is expressed as 4.8mm
Note. The diameter is expressed as 0.2 mm smaller to ensure that the selected catheter has a sufficiently large effective inner diameter and the selected bronchoscope can pass smoothly.
