The Cough-Assist T70 Effective, Safe and Simple  to Use. 


The CoughAssist T70 helps clear secretions from the lungs.  And therefore, it helps you with your breathing. When you breathe in (inspiration), the CoughAssist T70 gives you positive pressure air flow.  This helps expand your lungs. When you exhale, the CoughAssist T70 creates a sucking force (negative pressure).  This pulls the air out of your lungs.  This rapid change in pressure during the different phases of breathing (inspiration and expiration) makes your cough stronger and more effective. The addition of the CoughAssist T70 feature, called the Cough-Trak, allows you to synchronize treatment with your own breathing patterns.

The CoughAssist T70 Mechanical Insufflator-Exsufflator, or Cofflator, clears retained bronco-pulmonary secretions, reducing the risk of Respiratory complications. It comes standard with an adjustable internal inhale-flow restrictor and a simpler breathing circuit (filter, hose, adapter, mask).

The ability to cough is necessary for a healthy airway. The airway linings produce mucus which traps dirt and bacteria. This mixture of mucus, dirt and bacteria can be harmful if allowed to increase in quantity. Coughing is the body’s natural way of clearing mucus from the lungs and airways. Many respiratory diseases cripple the body’s ability to cough by weakening the muscles in the rib cage, neck and abdomen. This weakened condition interferes with your body’s ability to remove secretions, increasing the chance of respiratory infections. If coughing becomes too difficult for patients, doctors often prescribe the use of Mechanical Coughing Therapy.


Cough-Assist T70 Control and synchronization

The proprietary, integrated CoughAssist T70 Cough-Trak algorithm gives the user and caregiver the ability to initiate their therapy.  By triggering on  inspiration, this feature helps to synchronize the CoughAssist T70 therapy with the user’s own breathing pattern.  This allows for a more control and easier to tolerate CoughAssist therapy.  Users also report that this is a more comfortable and natural treatment.


Philips Cough-Assist T70 – Flexible Therapy 

The Philips Cough Assist T70 has three, highly customizable therapy modes – the ability to better tailor therapy to your exact needs and easily adjust treatment settings.  These settings include Manual, Auto, Advanced Auto.  The complete manual control over every aspect of treatment by a clinician or caregiver while the  fully automated treatment mode includes pressure settings, pre-therapy breaths and cough cycles.


CoughAssist T70 Secretion Loosening & Mobilization

The CoughAssist T70 also has an adjustable oscillation feature.  This feature enhances the loosening of mucus from the bronchial walls and increases mobilization of secretions.  This in turn improves bronchial drainage and increase the benefits of mechanical insufflation-exsufflation therapy.

CoughAssist T70 Non-Invasive Patient Interfaces

Instead of using a suction catheter into the airway, the CoughAssist T70 delivers therapy through either
  • a face mask,
  • a mouthpiece,
  • or a trach adapter used for the patient’s tracheotomy tube.

Common Questions

Using a process called mechanical insufflation-exsufflation, the CoughAssist gradually applies a positive pressure to the airway followed by a rapid shift to negative pressure. This rapid shift produces a high expiratory flow from the lungs, simulating a cough. The technique avoids airway damage and offers an alternative to an invasive procedure while still offering patients greater comfort and quality of life.

The Cough-Assist has been proven effective for patients with an insufficient ability to cough due to:

  • Poliomyelitis
  • Muscular Dystrophy
  • Spinal Muscular Atrophy
  • Amyotrophic Lateral Sclerosis
  • Myasthenia Gravis
  • Guillain-Barre Syndrome
  • Multiple Sclerosis
  • Or any other neurological disorder with some paralysis of the respiratory muscles, such as a spinal cord injury
  • Any patient unable to cough or clear secretions effectively due to reduced peak cough expiratory flow (less than 3 liters per second), resulting from high spinal cord injuries, neuromuscular deficits or severe fatigue associated with intrinsic lung disease is a candidate for the CoughAssist.
  • Any patient with a history of bullous emphysema, known susceptibility to pneumothorax, orpneumo-mediastinum, or known to have had any recent barotrauma, should consult with a physician before using.

The Cough Assist may be used with a facemask or mouthpiece. In addition, the Cough Assist can work with an adapter to a patient’s endotracheal or tracheostomy tube. It is also safe enough to be used on both adult and pediatric patients at home or in a hospital/institutional environment.

Cough Assist is a noninvasive respiratory therapy that safely removes secretions from patients suffering with an ineffective ability to cough. The Cough Assist Device clears secretions by gradually applying a positive pressure to the airway, then rapidly shifting to negative pressure. The rapid shift in pressure produces a high expiratory flow, simulating a natural cough.

Power Cord Information

All of our units have a universal power supply that accepts inputs from 110 – 230 V AC, 50 – 60 Hz. That means that you do not need a transformer to operate this system. We do however recommend a surge protector to protect the system against power spikes, especially if you are in an area where the local electrical grid is susceptible to spikes due to poor infrastructure or lighting strikes.

We supply a power cord for your home country, so if you are planning on traveling with your system, or if you are shipping to other than the destination country, please let us know.

  2. Select options: Style, Colour and Size.
  3. Add it to your cart.
  4. Pay by credit card or money transfer.

Do not purchase a vest larger than the patient’s chest size!

Purchasing a vest garment that is too large will result in ineffective treatment. Purchasing a vest garment that is larger than the actual chest circumference and hoping that children with just ‘GROW INTO IT’ is not a good idea. Extra vest garments for our customers that have purchased a system from us are $250.
