Embodiments of this invention relate to a fluid delivery device. The fluid delivery device comprises a fluid reservoir for containing a fluid, a first drive mechanism configured to remove a predetermined amount of the fluid from the fluid reservoir when the first drive mechanism is actuated, a needle, a septum and a housing having an orifice. Also disclosed is a method for dispensing a fluid from a fluid delivery device into a patient.

An injection device may include a housing, a container disposed within the housing, the container enclosing a fluid and having a first end and a second end, a conduit movable relative to the container, wherein the conduit is not in fluid communication with the fluid enclosed by the container while in a first position, and is in fluid communication with the fluid enclosed by the container and configured to deliver the fluid from the container to a patient while in a second position, and a lock that is removable from the housing, the lock having a first portion and a second portion.

A fluid delivery device comprises a hydraulic pump chamber having a hydraulic fluid. A fluid reservoir is coupled to the hydraulic pump chamber and is configured to contain a fluid deliverable to a patient. A first actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir. A second actuator is coupled to the hydraulic pump chamber and is configured to pressurize the hydraulic pump chamber and configured to transfer energy through the hydraulic pump chamber to the fluid reservoir.

The disclosed technology relates to a method for using a medicinal fluid injection device comprising 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.

Ambulatory infusion pumps, medicament reservoirs, and plungers, including both dynamic and static seals, plus related components, as well as component combinations and related methods.

An infusion set has a retraction dial that can be removably assembled with the infusion set and access a threaded needle hub contained therein such that the dial can be used to advance or retract a needle hub and an inserted needle to a more precisely controlled insertion depth to deliver insulin or other medicament intradermally (i.e. to the upper 3 mm of skin surface). Position of the inserted needle can be maintained by providing a separated and isolated needle hub, main base and main hub of the infusion set that can isolate the inserted needle from external forces such that the needle can be maintained at a depth to deliver content to the upper 3 mm of skin surface during normal use.

Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device is provided. The fluid infusion device comprises a housing defining a reservoir chamber for receiving a fluid reservoir. The fluid infusion device also comprises a drive system contained within the housing for dispensing fluid from the fluid reservoir. The fluid infusion device comprises a pressure management system at least partially defined in the reservoir chamber to manage air pressure in the reservoir chamber.

A device for delivering medicament into skin of a patient, the device having a housing, which includes a reservoir for housing the medicament, a first internal region that is sealed from fluid ingress and includes one or more components, and a second internal region that is not sealed from fluid ingress and includes one or more components. The housing also has a barrier that separates the first internal region and the second internal region, a delivery cannula that delivers the medicament into the skin of the patient, and a base including a bottom surface for orienting toward the skin of the patient. The bottom surface of the base has one or more fluid channels disposed therein and at least one of the fluid channels is in fluid communication with the delivery cannula.

A medicament delivery device comprises a housing containing a medicament delivery mechanism including an injection needle. The housing includes a contact surface having a first adhesive layer. The device further includes a sterilizing pad adhered to the housing. A second adhesive layer is formed proximate the sterilizing pad. A cover is detachably adhered over the sterilizing pad by the second adhesive layer and covers the sterilizing pad.

In an exemplary embodiment, a drug delivery device is configured for Body Channel Communication (BCC). The drug delivery device may include a conductive element embedded in an adhesive patch that secures the drug delivery device to the user. This conductive element acts as a coupler to the body of the user. Another conductive element may also be provided at a face of the housing. This conductive element acts as the other end of the coupler formed with the conductive coil in the adhesive patch. The conductive coil in the adhesive patch conforms well to the user's skin surface and thus facilitates a good quality coupling with the user.
