For the most accurate measurements, transducer should be warmed up for two minutes prior to use (no airflow required).
The detachable flow head (RX117A or RX117) is dishwasher safe.
Recommended sterilization: cold sterilization (i.e., Cidex) or autoclave.
Users may still perform their own calibrations using the optional FLOWCAL kit and downloadable template. The user calibration values are stored with the transducer, so the user calibration is applied on any computer to which the transducer is connected. The factory calibration may also be automatically restored by the user.
BSL 4.1.1 software is required to use the SS11LB. Earlier software versions will not recognize the transducer or apply the factory calibration.
Medium Airflow Head Connections
The SS11LB, TSD117A, and TSD117A-MRI transducers use flow head RX117A, which has multiple outer diameters to directly connect to the AFT36 filter/mouthpiece, AFT7L tubing, and other pulmonary products.
| AFT Series Part # | RX117A Flow Head Coupler/Combination/Notes |
| AFT1 | Direct connection to RX117A, but not recommended due to airflow restriction; use AFT36 in place of AFT1 + AFT2. |
| AFT6A | Not recommended for RX117A. Use FLOWCAL calibration kit. May still be connected to the RX117A using the AFT11A coupler included with the AFT6A. |
| AFT7L | Direct connection to RX117A. |
| AFT8 Autoclavable Mouthpiece | Either connect directly if sterilizing airflow head. If not sterilizing head can use AFT4 disposable filter (connect AFT8 to smaller diameter of filter, larger diameter to RX117A). |
| AFT9 Reusable Mouthpiece | 35 mm – replaced by AFT8 Autoclavable Mouthpiece; the AFT8 has a better fit with the RX117A. |
| AFT10 Disposable Facemask | AFT11H 35 mm OD/28.6 mm ID. |
| AFT12 | Direct connection to RX117A. Snug, but fits in the inner diameter of airflow head. |
| AFT13 (OBSOLETE) | AFT13 has been discontinued. Replaced by the AFT36 filter/mouthpiece. |
| AFT23 Low-cost T-Valve | Reusable mouthpiece: AFT4 + AFT8 + AFT11D 35 mm OD/35 mm OD Disposable mouthpiece: AFT36 + AFT11D 35 mm OD/35 mm OD |
| AFT26 2 L syringe | AFT11D 35 mm OD/35 mm OD. This coupler is included in the FLOWCAL calibration kit. |
| AFT36 Disposable Filter with Integrated Mouthpiece | Direct connection to RX117A. |
