Abstract:
The sensor inserting device (10) includes a device body (18), a movement mechanism (20) which inserts a detector (14) and an insertion needle (32) into a body of a patient by moving a sensor (12) with the insertion needle (32), and a dwelling member (24) which is arranged on a moving path of the sensor (12) and attached to the sensor (12) by movement of the sensor (12) caused by the movement mechanism (20). The dwelling member (24) is allowed to dwell on the skin of the patient with the sensor (12) and the transmitter (16) connected at a location in which the detector (14) is inserted into the body of the patient.
Abstract:
A continuous glucose monitoring system may include a hand-held monitor, a transmitter, an insulin pump, and an orthogonally redundant glucose sensor, which may comprise an optical glucose sensor and a non-optical glucose sensor. The former may be a fiber optical sensor, including a competitive glucose binding affinity assay with a glucose analog and a fluorophore-labeled glucose receptor, which is interrogated by an optical interrogating system, e.g., a stacked planar integrated optical system. The non-optical sensor may be an electrochemical sensor having a plurality of electrodes distributed along the length thereof. Proximal portions of the optical and electrochemical sensors may be housed inside the transmitter and operationally coupled with instrumentation for, e.g., receiving signals from the sensors, converting to respective glucose values, and communicating the glucose values. The sensors' distal portions may be inserted into a user's body via a single delivery needle and may be co-located inside the user's body.
Abstract:
An apparatus for supplying a fluid to a body of a patient and for monitoring a body characteristic of the patient has a base (100) adapted to secure the apparatus to the skin of a patient; a first piercing member (130) coupled to and extending from the base (100), wherein the first piercing member (130) is operatively coupled to at least one cannula for infusing a fluid to an infusion site; a second piercing member (120) coupled to and extending from the base (100) and operatively coupled to an electrochemical sensor having a sensor electrode (104) for determining at least one body characteristic of the patient at a sensor placement site; and infusion set tubing (160) adapted to connect to the cannula. The first and second piercing members (130, 120) are coupled to the base (100) in an orientation such that when the first and second piercing members are operatively coupled to the base and inserted into a patient, a first perforation channel made by the first piercing member is not in contact with a second perforation channel made by the second piercing member; and the first piercing member consists of two or more needles coupled to two or more infusion cannulae.
Abstract:
The invention provides for a medical device kit comprising a medical instrument (918) with a first connector (200, 946, 948). The first connector comprises at least one first electrical connection (204). The first connector further comprises a sealing cavity (212) at least partially surrounding the at least one first electrical connection. The sealing cavity comprises a sealing surface (114) and a wedging surface (214). The medical device kit further comprises a sealing cap (400). The sealing cap comprises a sealing tube (401) with an inner cavity (402). The sealing tube has a flexible tip region (404). The wedging surface is operable for forcing the flexible tip against the sealing surface to form a flexible tip seal (600) that seals the at least one first electrical connection within the sealing tube.
Abstract:
The invention provides for a sensor cartridge (100, 400, 500, 800, 900, 1000, 1300, 1400, 1500) comprising a sterile capsule (104). The sensor cartridge further comprises a sensor (108) within the sterile capsule. The sensor cartridge further comprises a sensor connector (120) connected to the sensor in an initial position (122). The sensor cartridge further comprises an insertion needle (106) for inserting the sensor into a subject (114). The insertion needle is within the sterile capsule. The sensor cartridge further comprises a sensor mounting unit (110) for receiving the sensor connector at a mounted position. The sensor mounting unit comprises an adhesive surface (116) for attaching to an exterior surface of the subject. The sensor cartridge further comprises an insertion mechanism (118) operable for actuating the insertion needle and moving the sensor connector from the initial position to the mounted position.
