In the fall of 2023 Aristeia completed the testing under Phase I of its CRADA with the Naval Medical Research Unit - San Antonio. Since 2020 the pull cord tourniquet has undergone sensor tests of three distinct prototype versions, namely the 4th, 5th and 6th generations. Measurements have been made using the HapMed Leg Tourniquet Trainer (CHI Systems, Fort Washington, PA) along with a Tekscan™ sensor system providing insight into the pressure distribution under the device. The tourniquet succesfully achieved the required 300 mmHg in the trials and changes were made to the design to improve specific areas in the distribution. The 6th generation prototype provides a satisfactory output on measured parameters.

As part of the work under ASTM E54 Tourniquet Task Group the pull cord tourniquet was also tested in an informal setting on the new fixture and achieved the required pressure levels on small and large limb sizes. The company aims to further contribute its device to this effort under the National Institute of Standards and Technology, which is funded by the Irregular Warfare Technical Support Directorate.

The need for extremity tourniquet devices is still prevalent in Ukraine and the company is determined to provide assistance on this matter. Upon completion of its ongoing validation efforts Aristeia aims to make its device available.
