An inventive medical device for transcutaneously inserting a cannula into body tissue. The device has a cannula with a wall that at least partially encloses a lumen. The device also has a patch for mounting onto skin of a user. The patch has a base and has a reservoir for storing a medical fluid. The patch also has a spring driven inserter. The inserter has a drive that urges the cannula from a storage position within the patch to an inserted position within the body tissue. The inserter also has a lock configured for securing the drive in a fixed position. The lock is fixedly connected to the drive and has a snap closure. Also disclosed is a medication pump that is fluidly connectable to the cannula. A method of transcutaneously using the medical device to transcutaneously insert a cannula into body tissue is also disclosed.

Blood glucose control systems are disclosed. A blood glucose control system can receive a glucose level signal from a glucose sensor operatively coupled to a subject. The system can decode encoded data of the glucose level signal to obtain the glucose level of the subject and the indication of the glucose trend. The system can automatically calculate the dose control signal using a control algorithm configured to calculate regular correction boluses of glucose control agent in response to at least the glucose level of the subject. The system can select a dose control signal encoding profile from a plurality of dose control signal encoding profiles and, based on the dose control signal encoding profile, encode the dose control signal such that the pump controller can read the dose control signal. The system can transmit an encoded dose control signal to the pump controller.

The present invention generally relates to collecting, determining and/or transmitting information associated with the process of receiving bodily fluid through a device opening and/or delivering substances to a subject. In one aspect, the device includes an information collecting portion and a fluid receiving portion. In another aspect, the two portions are constructed and designed to attach to one another. In one embodiment, actuation of one of the portions causes the other portion to actuate. Methods of time keeping and information transmission are also discussed.
