Neurostimulation device could help prevent the onset of DVT

The ‘Geko’ uses patented technology dubbed OnPulse, which was invented by Prof Arthur Tucker at Queen Mary University.

OnPulse allows the device to emit a 27mA current to the back of the knee, causing the calf muscle to contract and stimulating blood flow.

‘The neurostimulation device stimulates the peroneal nerve,’ explained Jeff Hickman, chief financial officer and head of business development at Sky Medical Technology. ‘It just so happens that architecturally, in the body, that nerve is very close to the surface of the skin so it’s very easy to stimulate.

‘You will feel an involuntary firing of your muscles — very similar to when a doctor uses the mallet and hits your knee to test your reflexes.’

The disposable device sticks onto the leg and will be particularly useful for elderly or disabled people who do not have the ability to walk around an aircraft on longer flights. Hickman said the battery-powered Geko increases blood flow by a factor of four for someone who is sitting down.
