Autoclavable Spacer Chamber With Cross Valve Technology, Each (SP-SPAP-R)

The Autoclavable Spacer Chamber With Cross Valve Technology is a valved holding chamber (VHC) designed for use with pressurized metered-dose inhalers (pMDIs). It is intended to optimize aerosol drug delivery to the lower respiratory tract in patients with asthma, COPD, and other obstructive airway diseases.

 

Device Function and Mechanism

This spacer chamber attaches directly to a pMDI and acts as an intermediary reservoir that temporarily holds the aerosolized medication after actuation. By separating actuation from inhalation, the device:

• Reduces oropharyngeal deposition

• Improves pulmonary drug delivery

• Minimizes coordination errors between actuation and inhalation

• Decreases systemic side effects caused by improper inhaler technique
