An entrepreneur with a 'life saving' product got the backing of a dragon on tonight's Dragon's Den.
Paul Westerman from Cambridgeshire pitched his product to dragons Deborah Meaden, Peter Jones, Touker Suleyman Sara Davies and new dragon, Steven Bartlett.
He hoped for an investment of £50,000 for 15% equity for his RBR Legflow product - a deep vein thrombosis (DVT) prevention device.

Paul told a heartbreaking story of how he had collapsed and nearly died after suffering a 'massive bilateral pulmonary embolism'.
He explained he had injured his knee a few weeks beforehand and it unknowingly resulted in DVT in his right leg.
Paul nervously said: "I survived obviously... fortunately."
His product helps to increase blood flow to the legs to lessen the chances of developing deep vein thrombosis.
Dragon Peter Jones admitted that he understood how important the product could be as he ended up in hospital after a long flight due to not moving for a long period of time. He said since that he moves his legs all of the time and knows it can be a real issue.
He said: "I think it's a good product that you've come up with. It could go into airlines and of course care homes - very very important."
So it was surprising when he opted out of investing.
While Deborah Meaden wanted to know what Paul has done to protect his product from copyright, and Steven Bartlett thought the product couldn't compete with modern technology, Touker Suleyman still seemed interested.
He thought the entrepreneur needed a chance to show his product to the right people including the NHS and airlines as he said: "I'm willing to explore the unknown."
He offered the £50,000 for 35% equity rather than the 15% and Paul replied: "I'm more than happy with those terms and I would love to be working with you."
Fans on Twitter were delighted to see the businessman had received the help needed from a dragon.

Where can you buy RBR Legflow?
The Legflow device which was seen on Dragon's Den comes from RBR Active Limited.
It can be bought from the RBR Active website for £12.99 and is a reusable product.
The product is also available from Amazon.
What does the RBR Legflow do?
The RBR Legflow device is clinically-tested to significantly increase blood flow in the lower limbs.
Through three simple exercises, the RBR Leg Flow improves lower limb blood flow over 10-fold, helping to minimise the risk of developing deep vein thrombosis.
The website describes it as: "The RBR Legflow is highly effective where long periods of inactivity are unavoidable.
"This can include travelling by air, working in an office, being hospitalised, online gaming, recovering from an operation or simply if you spend large amounts of leisure time sitting still.
"The RBR Legflow is a small medical device that sits on the floor under foot, incorporating two separate round domes with patented nodules®, each large enough to accommodate the user’s foot."
Dragons' Den airs Thursdays at 8pm on BBC One
