Medical Ventilators – Witnessing Increased Patent Filing Trend In Recent Years

Published on 07 Mar, 2014

  • Medical ventilator domain has witnessed increasing patent filing trend over the last five years
  • Most of research origination in ventilator has been undertaken in USA, followed by China in past five years
  • Asia Pacific countries such as China, Korea and India became a preferable country for filing patents due to growing economy, insurance sector and health care awareness. A report by Global Industry Analysts says Asia-pacific ventilator market is growing at CAGR of over 9.5% from 2013 to 2019.

Resmed, Philips, Nellcor Puritan Bennett (Covidien), Draeger, GE, Hamilton are global leading ventilator manufacturers. Ventilator market is rising at a CAGR of 6.6% and is expected to reach USD 4.2 Billion globally in 2019.The market in terms of revenue is dominated by United States.

The medical ventilator domain has witnessed increasing patent filing trend over the last five years. Research in ventilator is mainly driven by:

  • Algorithms for detecting patient’s condition and controlling ventilator settings based on them.
  • Display device for displaying vital pulmonary parameters of the patient such as respiratory waveforms, ventilation mode, alerts and ventilator control options.
  • Non-invasive techniques for sensing parameters to control ventilator such as impedance imaging tomography, pulse oximetry etc.
  • Single ventilator having compatibility with the patients of all age groups (neonatal, paediatrics and adults)

Most of the research in ventilators is undertaken by ventilator manufacturing companies. University and research institutes are less involved in the domain.

Critical care ventilators, Portable ventilators, transportable ventilators, neonatal ventilators are major broadly defined product segments for ventilator. Due to potential cost savings and more sophisticated functionality, portable ventilators

In coming decade the ventilator will in greater synch with other medical devices such as ECG, pacemaker, MRI. Also with advancement in medical communication protocol, doctors will be able to monitor patient condition on their PDA, iphones and will be able to remotely control the life saving medical devices.

About Medical Ventilator

About Medical VentilatorsMedical Ventilator is a machine for mechanically providing and extracting air from the lungs. It is used for the patients who are unable to breath with their own efforts or have breathing insufficiency. According to US medical device classification system, ventilators are class III devices and require strict Premarket Approval and FDA clearance before commercial launch.

Early in 18th century mechanical ventilators were colloquially referred as “Iron Lungs”. They work on the principle of negative ventilation, where the patient is placed in the machine’s air-tight cavity, and machine periodically applies negative pressure to suck air within the cavity. A door allows the head and neck to remain free. Application of negative pressure causes diaphragm to expand and patient inhales air from atmosphere, causing breathing action. Negative pressure ventilators are obsolete globally since 2004.

Modern ventilators are computer controlled positive pressure ventilators. They sense the quantity of air required by the patient, air saturation in the blood and other physiological parameters in real time. They have algorithms, which control the internal valves, to provide air with different gas proportions, volume and pressure depending on the patient’s age and disease type.
