Here are the key features and benefits of this spacer: Valved Holding Chamber (VHC): The spacer serves as a reservoir between the pMDI and the patient's mouth, allowing aerosol medication to be dispensed into the chamber before inhalation. This helps to reduce the delivery of large aerosolized particles directly into the mouth. Minimization of Large Aerosolized Particles: By holding the medication after aerosolization, the spacer minimizes the direct delivery of large aerosolized particles into the mouth, ensuring that the medication is targeted towards the lower airways where it is needed for effective treatment of conditions such as asthma or COPD. Anti-Static Design: The spacer is constructed with an anti-static material, which helps to minimize the build-up of static charge that can potentially interfere with the delivery of aerosol medication. Hand-Held and Portable: The collapsible design of the spacer makes it convenient for patients to carry and use wherever they go, providing a portable solution for administering medication on the move. Single Patient Use: Intended for single patient use to prevent cross-contamination and ensure hygiene standards are maintained. Overall, the Breath-A-Tech Anti-Static Collapsible Spacer offers a practical and effective solution for optimizing the delivery of aerosol medication from pMDIs, providing patients with a convenient and portable option for managing respiratory conditions such as asthma or COPD.
