Provided is a fill closure tab or an infusion device incorporating the same. The fill closure tab includes a gripping portion, and seals an insertion mechanism opening with a hydrophobic membrane. The fill closure tab further includes a fill assist mechanism shaped to assist with directing a filling device such as a pen needle or syringe to a fill port of the infusion device.

Various exemplary methods, systems, and devices for injection pump needle mechanics are provided.

The present disclosure relates to a liquid medicine injection device including a patch portion to which a sensor portion configured to measure blood glucose is detachable and in which an injection portion configured to inject a liquid medicine into the body of a user is installed, and a stamping portion on which the patch portion is mounted and including a first needle connectable to the sensor portion, wherein the stamping portion transmits power to the patch portion so that the first needle and a second needle, which is connected to the injection portion, are together inserted into the skin of the user, and the sensor portion and the injection portion are installed in a single device so that the convenience of use is improved when the liquid medicine injection device is attached to the skin of the user.

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.

A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.

A wearable drug delivery device, techniques, and computer-readable media that provide an application that implements a diabetes treatment plan for a user are described. The drug delivery device may include a controller operable to direct operation of the wearable drug delivery device. The controller may provide a selectable activity mode of operation for the user. Operation of the drug delivery device in the activity mode of operation may reduce a likelihood of hypoglycemia during times of increased insulin sensitivity for the user and may reduce a likelihood of hyperglycemia during times of increased insulin requirements for the user. The activity mode of operation may be manually activated by the user or may be activated automatically by the controller. The controller may automatically activate the activity mode of operation based on a detected activity level of the user and/or a detected location of the user.

A device for injecting a product into a site, having: a body provided with a bearing wall for bearing on the site, a needle support mounted so as to be movable with respect to the bearing wall between: a pre-insertion position, at least one insertion position, and at least one retracted position, a catheter mounted so as to be movable with respect to the needle and intended to dispense product into the site, a drive unit intended to translate the needle support between the various positions of the needle support, a pump connected to a reservoir so as to transfer product from the reservoir to the catheter, a single electric motor intended to drive the drive unit and to supply the pump.

Integrated sensor and infusion devices are disclosed herein. The present technology includes, for example, an integrated sensor and infusion device for sensing physiological parameter(s) and delivering a medicament to a body of a user based at least in part on the sensed parameter(s). The device can comprise an insertion assembly comprising a carrier assembly comprising a cannula carrier, a trocar assembly removably coupled to the carrier assembly, and a drive assembly comprising a torsion spring coupled to the trocar assembly such that, when actuated, the torsion spring rotates to drive the trocar assembly and the carrier assembly axially downward to insert an infusion cannula and sensor electrode into a user's skin. The drive assembly can comprise a plurality of coupled drive wheels and/or a scissor assembly with multiple interacting links.

A drug delivery device includes a housing with at least one pressure communication channel or aperture, which distributes a negative fluid pressure across its base to draw tissue against the device. The device can also include a porous, adhesive layer over the channel(s) or aperture(s), for attaching to tissue. The device can also include a pressure sensor for determining whether there is proper attachment. Further, a bladder may be used instead of the adhesive layer for attaching the device. The bladder, in a partially inflated state, can apply constant pressure across a contact surface causing a flexible adhesive layer attached to the bladder to confirm and adhere to the tissue. Subsequent evacuation of the bladder causes it to deflate and collapse or retract, thereby causing the flexible adhesive layer to pull and stretch the tissue toward the base.

The disclosed technology relates to medicinal fluid injection devices. In one aspect, a medicinal fluid injection device includes a housing having an opening in a side surface thereof, a storage container arranged inside the housing and configured to store a medicinal fluid, an injection needle connected to the storage container and configured to inject the medicinal fluid when stored in the storage container through the opening, and a cover body covering the opening, wherein the cover body includes a cover part configured such that the a shape of the cover part changes according to air pressure caused by the injection needle.
