Ambulatory Impedance/pH Monitoring Systems: Alpha Wireless pH Monitoring Capsule

The Alpha Wireless pH Monitoring Capsule is the newest advance in ambulatory reflux monitoring.

The system comprises of a small pH Capsule with delivery device, data recorder, calibration stand and analysis software. A small pH capsule is fixed to the oesophageal mucosa via vacuum suction using a straightforward delivery device with a simple 3 step, slide and click process, reducing the risk of issues with either deployment or attachment of the pH capsule. Unlike conventional pH monitoring using trans-nasal catheters, patients are less aware of the procedure and more likely to maintain their regular lifestyle, activities and diet providing the clinician with a more realistic profile of the frequency and severity of the acid reflux. The pH value within the oesophagus is monitored continuously for 4 full days (96 hours) of acid detection. Data is transmitted wirelessly to the external data recorder, worn with either a shoulder strap or belt. The capsule will naturally drop from the mucosa and be excreted out.

Upon completion of the recording the data is uploaded and analysed via the computer software Physicians can quickly manage and calibrate devices, following simple and intuitive steps. They can also perform various calculations including SI, SSI and SAP, custom and export reports.

Advantages of the Alpha Wireless pH Monitoring Capsule System include:

• Simple capsule deployment, using 3 slide switches, straightforward with no failure of detachment from delivery system.
  
  
• Improved data integrity (data is temporarily stored in capsule before transmission to data recorder)
  
  
• Up to 96 hour recording allowing for 4 full days of acid detection
  
  
• Dry reference electrode resulting in longer shelf life
  

Traditional pH recording only records acidic pH reflux episodes. Impedance/pH detects both acidic and non-acidic reflux episodes. Combined Impedance pH recording is clinically useful in the evaluation of symptoms under PPI therapy, as well as for hoarseness, unexplained cough, and applications of particular interest.
