A method for dynamic pressure control during a multiphase injection is described wherein the pressures of fluids in the various reservoirs of a fluid delivery system are controlled to provide desired fluid delivery parameters. The methods include advancing the first drive member to expel the first fluid from the first reservoir into a conduit, wherein the fluid is pressurized to a first fluid pressure; measuring the first fluid pressure to provide a target value; while the second reservoir is in fluid isolation from the conduit, advancing or retracting the second drive member to increase or decrease the fluid pressure of the second fluid in the second reservoir to the target value; placing the second reservoir in fluid communication with the conduit; and advancing the second drive member to expel the second fluid from the second reservoir into the conduit.

An implantable cranial medical device includes a first fluid flow path, a second fluid flow path, and upper flange portion, and a lower portion. The upper flange portion is configured to rest on a skull of a subject about a burr hole. The lower portion is configured to be placed within the burr hole. The first fluid flow path may extend from a first opening in the upper flange portion to a first opening in the lower portion. The second fluid flow path may extend from a second opening in the upper flange portion to a second opening in the lower portion.

The present disclosure provides improved methods for calibrating the zero position of at least one drive member of an injector system is disclosed. Automated methods of position calibration of the drive member of a fluid injector are disclosed. These methods address sources of error in positional accuracy and fluid delivery inaccuracies, such as disposable syringe tolerance and injector wear over time. According to other embodiments of the present disclosure, methods and fluid injector systems for determining and correcting for the amount of slack in a fluid injection apparatus are described. An understanding of the calibration and the amount of slack in a fluid injection system allows a processor to correct for the slack, thereby ensuring more accurate fluid delivery to the patient and more accurate imaging processes.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

The disclosed embodiments are directed to a wearable automatic drug delivery device configured to provide basal dosing of GLP-1 or co-formulation of GLP-1 and insulin. The size and frequency of the basal doses may be controlled by a medication delivery algorithm resident on the wearable drug delivery device based on a basal dosing history and readings from a continuous glucose monitor monitoring the glucose levels of the wearer of the device.

A delivery device for intravenous delivery of microparticles to a patient. The delivery device is fluidly connectable to (i) a first source of an injection medium and (ii) a second source of an injection medium. The delivery device includes: a first fluid inlet fluidly connectable to the first source of the injection medium, a fluid outlet, a fluid mixer fluidly connecting the first fluid inlet to the fluid outlet, a second fluid inlet fluidly connectable to the second source of the injection medium, and a source of microparticles fluidly connecting the second fluid inlet to the fluid mixer. When fluid flows from the second source of the injection medium into the delivery device: the second injection medium fluidly drives microparticles from the source of microparticles into the fluid mixer, and the fluid outlet dispenses to the patient an injection medium that includes the microparticles.

Multi-medicament infusion systems prevent cross-channeling of medicaments. A system may include one or more of an infusion pump, medicament reservoirs, a multi-channel fluid conduit, and an infusion set. Medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system under selected configurations.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

A flow control device includes a housing having a primary valve body defining a primary inlet and an outlet, a secondary valve body defining a secondary inlet, and a chamber defined by an inner circumferential surface of the housing and fluidly connecting the primary and secondary inlets with the outlet. The primary and secondary inlets share a common central axis perpendicularly disposed to a central axis of the outlet. A valve member is reciprocally mounted in the chamber to block fluid communication between the secondary inlet and the outlet when fluid pressure into the primary inlet is higher than fluid pressure into the secondary inlet, and) block fluid communication between the primary inlet and the outlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.
