摘要：
A needle dislodgement and blood leakage detection device includes a sensor assembly having a flexible sensor and an alarm device to which the sensor assembly is mounted. The flexible sensor includes two blood leakage detection electrodes that circumferentially surround a needle piercing site. The blood leakage detection electrodes are contactable by a needle crossing therebetween to get shorted or are contactable with blood leaking out of the needle piercing site to get shorted. The alarm device may be placed on a body surface of a patient and electrically connected to the blood leakage detection electrodes so as to issue an alarm message when the detection sections are shorted. The flexible sensor is designed to have a thin plate flexible structure, so that the flexible sensor can be levelly attached onto the patients skin surface and deformable with the bending of a limb of the patient without pressing fistula or other vessels, making it applicable to blood leakage detection during blood transfusion and hemostasis process, which is very convenient and practical.一種脫針與漏血偵測裝置,包含一個具有一撓性感測器的感測組件,及一供該感測組件安裝之警示器。撓性感測器設置有兩個用以圍繞於該扎針處周圍之漏血感測電極,該等漏血感測電極可被一支針跨接導通而短路或被扎針處露出之血液接觸導通而短路。警示器可安裝於該患者體表,可電連接於該等漏血感測電極,可於該等感測段導通短路時發出該警示訊息。透過該撓性感測器之薄片狀可撓曲結構設計,使得該撓性感測器可隨肢體彎曲變形地平整伏貼設置在患者體表,且不會對廔管或其它血管產生壓迫,可應用於輸血過程與止血過程之漏血偵測,相當方便實用。2‧‧‧感測組件3‧‧‧撓性感測器31‧‧‧撓性基板310‧‧‧扎針空間311‧‧‧對位部312‧‧‧延伸部313‧‧‧翼片部32‧‧‧漏血感測電極321‧‧‧第一感測段322‧‧‧第一延伸段323‧‧‧第一導接段33‧‧‧絕緣膜4‧‧‧警示器41‧‧‧殼體單元411‧‧‧殼本體412‧‧‧套束件42‧‧‧導電端子431‧‧‧電源開關44‧‧‧警示單元441‧‧‧發光元件442‧‧‧警報元件455‧‧‧重置鍵
