How to smooth data to a negative curve

I'm looking to smooth out some experimental data.
Some recorded data points go upwards, altough this isn't possible for the given subject. Is there a way to smooth my data and at the same time, make sure that x_i < x_i-1, i.e., always with a negative curve.

Thie File Exchange submission allows you to do spline smoothing with monotonicity constraints:
You can also do Gaussian+constant fitting with the following File Exchange submission, and with bound constraints on the mu parameter:
With mu<=0, that would ensure monotonic descent over the range of your data.
