Breath-a-tech cardboard spacer is a portable hand held spacer designed to optimise the delivery of aerosolised asthma and COPD medication from most pressurized metered dose inhalers (pMDI) or puffers. Suitable for emergency use, first aid kits and when you need a portable solution and can used up to 7 days. The cardboard spacer is for single patient use and does not need priming before use, so it can be used straight out of the package. The cardboard spacer is designed to improve the delivery of asthma and COPD medication to the small airways deep within the lungs. Suitable for out of home use, including hospitals, emergency services and clinics.
