Able spacer

Transparent valved holding chamber

Able Spacer is a popular valved inhalation holding chamber that facilitates the use of pMDI medication. This improved version of Able Spacer is now manufactured in the UK, from transparent plastic which incorporates anti-microbial silver ion technology. It also provides improved protection from contamination, and inhibits microbial growth. The visible valve movement makes it easier for parents or carers to observe and confirm correct inhalation and actuation.

Special polymer

Inhibits the growth of bacteria and fungi

Able spacer is manufactured from a special polymer that incorporates silver ions, which inhibit the growth of bacteria and fungi. Research has demonstrated that microbes will opportunistically establish colonies inside spacer devices.

CCI’s own research has shown that under certain circumstances drug residues may encourage the growth of certain bacteria. Regular washing of spacers is very important. The polymer is free from latex, phthalates and BPA

Universal inhaler port

Delivers correct drug dose

All spacers and valved holding chambers are designed to deliver the equivalent dose of a correctly used metered dose inhaler.

Able spacer fulfils this requirement and has repeatedly demonstrated this with different drug formulations. The universal inhaler port fitting ensures compatibility with all sizes of aerosol inhalers.

Positive coaching whistle

Unlike many others

Able spacer, unlike many other spacers, deliberately does not incorporate a negative alert whistle. Such whistles have been shown to produce misleading and contradictory feedback (Ref Sanders PCRJ Dec 2013).

Able spacer can be used with a positive coaching whistle (Flo-Tone) to encourage correct use.

Low-static ABS polymer

Reduces static properties

Able spacer is manufactured from a low-static ABS polymer. The component parts are protected from static in manufacture and supplied in anti-static bags.

Static in chambers can reduce drug delivery and measures that reduce static are important, especially detergent washing (see instructions).

Taking the dose

Visible valve movement

Able spacer is strictly speaking a valved holding chamber because the one way valve protects the dose in the chamber from being dispersed on exhalation. The transparent body design enables an observer to see valve movement confirming successful use.

The valve is made with features that make it easy for the valve to open on inhalation, permitting the dose to be delivered. On exhalation air is diverted away through two outlets.

Methods of inhalation

Inhalation to be prompt after spray

After spraying medication into the chamber the patient may take their dose either by taking a single deep inhalation or by taking multiple shallow inhalations (tidal breathing).

The medication will remain as a cloud for about 10 seconds, so inhalation should follow spraying fairly promptly.

What lies behind the mask

Anti-static material

Able spacer is designed to be used alone (mouthpiece) or with a face-mask. The face-mask is manufactured from a special soft polymer.

Unlike conventional spacer masks (usually made of silicon – which has a high static load), Able spacer masks are anti-static and do not diminish the dosage available to the patient (Ref Poster ISAM).

The masks are free from phthalates, latex and BPA.

Mask formats

Different sizes available

Able spacer masks are available in small, medium and large sizes, to suit all ages. The masks have a soft fit feature that facilitates good fitting. A good fitting mask is essential for successful drug delivery.
