Cleaning Instructions

 
Treatment Control Unit (TCU)

 

The TCU is a resusable medical device that must be properly maintained to prevent infection, worsening of existing infection, or cross-infection.

 

The TCU should undergo surface disinfection: 

  • if it should become contaminated with sputum or bodily fluids,

  • after the last treatment of the treatment day, and/or

  • in the hospital, when it is discontinued from one patient and moved to another.

 

Clean all external surfaces of the TCU with a pre-moistened germicidal wipe or cloth product containing dimethyl-benzyl-ammonium chloride and/or dimethyl-ethylbenzyl-ammonium chloride (Clorox® Wipes or equivalent). Be sure to allow the appropriate contact time as specified by the product’s instructions. Ensure that moisture does not enter the case of the TCU at the seams or at the two electrical ports. The control buttons on the faceplate are sealed against moisture entry.

 
Hand-held Transducer (HHT) and Associated Parts

 

The HHT is a single-patient use disposable device that is designed to be used for the duration of a patient’s hospital stay, but not to exceed 30 days. It is supplied non-sterile.

 

To clean the HHT, remove the Y-adapter, mouthpiece, variable expiratory resistor and screw-on cone. Remove Circulaire, if present. Clean the outside surface of the HHT and the transducer diaphragm with a pre-moistened germicidal wipe or cloth product containing dimethyl-benzyl-ammonium chloride and/or dimethyl-ethylbenzyl-ammonium chloride. Allow the appropriate contact time as specified by the product’s instructions. Allow the surface to dry before reassembling and using.

 

Clean the Y-adapter, mouthpiece, variable expiratory resistor and screw-on cone with soap and water, rinse, and then disinfect the parts by soaking in alkyldimethyl-benzyl ammonium chloride for 10 minutes. Rinse with sterile water and allow the parts to air dry. Remove the nebulizer and clean according to the nebulizer care instructions.

 

Optional Aerosol Delivery System (Circulaire II Hybrid)

 

The Circulaire II Hybrid aerosol delivery system should be removed from the HHT at the end of each treatment session and cleaned according to hospital nebulizer cleaning policy. The reservoir ball may be air-dried by standing it on its flange on a clean surface to allow drainage. The entire Circulaire II Hybrid may be changed out as frequently as desired according to hospital policy.

Cleaning instructions for the Circulaire II Hybrid may be found in the Circulaire II Hybrid Instructions for Use package insert which is available for download as a PDF file.
