Biography
[edit]Barbro Hjalmarsson invented the battery-powered blood cradle "Triomix", which automatically shakes a test tube with blood so that the blood cells are separated from the blood plasma correctly. Her invention saved both the time it took to turn each tube 10-12 times as well as increased quality in the test by avoiding human error.[1] She was granted a patent in 1994 for this "Mixing apparatus comprising a mixing plate intended for receiving test tube tubes, which is imparted to a rocking movement of a certain frequency".[2] Her invention reduced the manual work and made the sampling safer.[3]
