Hilda Barbro Hjalmarsson (born December 10, 1919 in Viby socken, Närke, died February 13, 2012 in Degerfors ) was a Swedish nurse and inventor.

Barbro Hjalmarsson invented battery-powered blood cradle "Triomix", which automatically shakes test tubes with blood in order to separate blood cells from blood plasma, used for example in erythrocyte sedimentation rate tests.

Hjalmarsson was granted a patent for her invention in 1994.
