The multifunctional member for improvement of the active tourniquet adopts data transmission module and GPS receiver, which can be a accessory of the tourniquet. The member has such functions as time alarm, identification and locating of the casualty.

AIM: To appropriately modify the defects of active tourniquets in order to act as various tourniquet attachments in Chinese Army.METHODS: This attachment is classified into individual-solider end and searching-rescue end, and data at both ends are collected and transmitted by using wireless data transmission module. Individual-solider end is composed of timing alarm circuit, bit display tube and GPS module, etc. and the data are processed by using single chip of wireless data transmission module. Searching-rescue end adopts the same data transmission module as individual-solider end, and port connects to computer in order to realize two-dimensional data delivery and communication to individual-solider end by using computer-controlled software, i.e. battleground immediate pursuit rescue system.RESULTS: As various tourniquet attachments, individual-solider end is characterized by timing alarm function in the phase of installing tourniquet. Necessarily, we may start searching-rescue function, and the matching with searching-rescue end may realize personal identification and localization of wounded soldiers.CONCLUSION: As a common tourniquet attachment, it is provided with installing alarm, personal identification and localization of wounded soldiers; however, its function is still thin. It brings a lot of evidences for further improvement through installing a physiological probe at individual-solider end to collect physiological data and distantly monitor real-time vital signs of wounded soldiers.
