    • A medical device (110) for detecting at least one analyte in a body fluid, a method of using a medical device (110) and a method for assembling a medical device are disclosed. The medical device (110) comprises:
      - at least one analyte sensor (122) having an insertable portion (160) adapted for at least partially being inserted into a body tissue (194) of a user,
      - at least one electronics unit (172), wherein the analyte sensor (122) is operably connected to the electronics unit (172), wherein the electronics unit (172) comprises at least one interconnect device (174) with at least one electronic component attached thereto;
      - at least one insertion cannula (114), wherein the analyte sensor (122) partially is placed inside the insertion cannula (114);
      - wherein the insertion cannula (114) is movable in between at least one extended position (224) and at least one retracted position (222), wherein the electronics unit (172) remains in a fixed position (225) when the insertion cannula (114) is moved from the extended position (224) to the retracted position (222) or vice versa;
      - wherein the analyte sensor (122) comprises at least one active portion (148) having at least one sensor electrode (208) for sensing the analyte thereon;
      - wherein the analyte sensor (122) further comprises at least one passive portion (152) electrically connected to the electronics unit (172) in at least one connector portion (206);
      - wherein the passive portion (152) provides, in between the connector portion (206) and the active portion (148), at least one reserve loop (150) configured for compensating for an insertion path during movement from the retracted position (222) into the extended position (224) or vice versa.
    • 公开了一种用于检测体液中的至少一种分析物的医疗装置(110),使用医疗装置(110)的方法以及组装医疗装置的方法。 医疗设备(110)包括: - 至少一个分析物传感器(122),其具有适于至少部分地插入使用者的身体组织(194)中的可插入部分(160), - 至少一个电子单元 ),其中所述分析物传感器(122)可操作地连接到所述电子单元(172),其中所述电子单元(172)包括至少一个互连装置(174),其上连接有至少一个电子部件; - 至少一个插入套管(114),其中分析物传感器(122)部分地放置在插入套管(114)内; - 其中所述插入套管(114)可在至少一个延伸位置(224)和至少一个缩回位置(222)之间移动,其中当所述插入套管(114) 114)从伸出位置(224)移动到缩回位置(222),反之亦然; - 其中分析物传感器(122)包括具有用于感测其上的分析物的至少一个传感器电极(208)的至少一个有源部分(148) - 其中分析物传感器(122)还包括在至少一个连接器部分(206)中电连接到电子单元(172)的至少一个无源部分(152); - 其中所述无源部分(152)在所述连接器部分(206)和所述有效部分(148)之间提供至少一个保留环(150),所述至少一个保留环配置用于在从所述缩回位置(222)移动期间补偿插入路径, 进入延伸位置(224),反之亦然。
