The tourniquet structure-improved system of the tool separate type timer of this creation includes a band body, a pedestal and a timer ontology. The band system appropriate location that affected part is corresponded to tightly around what for user； The pedestal combination what band body, and can be slided on the what band body； Timer this system separably combines the what pedestal, can be with sliding on the pedestal what band body. Thereby, the appropriate location that affected part waits stopping blooding is corresponded to tightly around what using band body, timing is carried out automatically through timer ontology again, medical staff or patient can understand the time wound by timer ontology, in time allow unobstructed blood to stop blooding again in what safety time, avoid the problem that because stop blood too long caused by meronecrosis. And timer ontology separably installs the pedestal on what band body, therefore timer ontology can be removed and individually be charged or cooperate scheduling installing another band body of what, thereby, it can reduce and eliminate the cost spent by changing because whole, and the replaceable clean new band body of medical staff is used for new sufferers, avoids the problem that generating blood cross-infection because of reuse.本創作之具分離式計時器之止血帶改良結構係包括一帶體、一底座與一計時器本體。帶體係用以供使用者緊繞於對應患部之適當位置；底座結合於該帶體，並可於該帶體上滑動；計時器本體係可分離地結合於該底座，可隨該底座於該帶體上滑動。藉此，利用帶體緊繞於對應患部待止血之適當位置，再透過計時器本體自動進行計時，醫護人員或是患者可由計時器本體了解已纏繞的時間，適時地於安全時間內讓血液暢通再進行止血，避免因阻擋血液過久所造成細胞壞死的問題。而計時器本體可分離地裝設於帶體上之底座，故可將計時器本體取下單獨進行充電或是配合調度裝設於另一條帶體，藉此，可減少因整體汰換所耗費的成本，且醫護人員可更換乾淨的新帶體供新病患使用，避免因重複使用而產生血液交叉感染的問題。
