Annual insurance for Health cover

[peebee]

We normally take out annual travel insurance to cover us when we visit our house in France usually about 5 times a year.  We have just received our reminder for the annual premium.  The cover includes flight delays and all the usual things about lost baggage etc. that travel insurance usually covers. However, we only want the insurance for the health side of things and wonder if anyone has managed to find insurance that just covers this?

Thanks
