The Blom-Singer^® SpeakFree™ HME Hands Free Valve is an innovative product combination consisting of a speaking valve and a permanently integrated HME filter. For laryngectomised patients with a voice prosthesis, this product combines all the advantages of an HME, i.e. heating, humidifying and filtering the breathing air, with the advantage of a speech option without requiring the use of fingers.

The Blom-Singer^® SpeakFree™ HME Hands Free Valve is the first to offer an HME cassette with an integrated, customisable disposable speaking valve. The primary product feature, the HME function, is intended for pulmonary rehabilitation.

Two different HME filter qualities (Classic Flow^® or Easy Flow^®) are available to choose from to be able to use the appropriate breathing resistance for a comfortable breathing and speech situation. The Classic Flow^® HME achieves high humidification, warming, filtering of the breathing air and adequate breathing resistance after laryngectomy. The lower resistance of the Easy Flow^®HME is suitable for use during physical exertion while providing suitable breathing gas conditioning results at the same time (heating, moistening, filtering). If the HME filter is soiled by secretion or dirt particles, it must be changed for hygienic reasons.

The secondary product feature of the Blom-Singer^® SpeakFree™ HME Hands Free Valve, the speech valve, promotes voice rehabilitation. A special internal speaking membrane allows unhindered inhalation and exhalation in the open membrane position. Only when the blowing pressure is increased does the speaking valve close automatically and make phonation possible via voice prosthesis. The very individual adjustment options via the two HME variants and the grid-free adjustment of the membrane opening enable exceptionally good phonation results. Particularly in everyday situations, this system simplifies adjustment of the membrane opening as required.

The smoothly turning housing enables the best possible adjustment of the internal speech membrane during use. This way, the membrane opening can be optimised during use according to the situation, for example during physical exertion. A satisfactory speaking result is achieved or restored immediately without the use of fingers. In addition, the Blom-Singer^® SpeakFree™ HME Hands Free Valve eliminates the need for daily cleaning of the speaking valve in support of hygienically beneficial single use. The transparent and particularly flat design also ensures a skin-colour-friendly match and makes for a very discreet appearance. The Blom-Singer^® SpeakFree™ HME Hands Free Valve is compatible with all tracheostomy tubes or base plates with a 22 mm connector.
