According to one example of the present disclosure an infusion device is configured to control a medication delivery apparatus to intravenously deliver a pharmaceutical preparation to a patient. The infusion device comprises a processor and a memory storing instructions executable by the processor to cause the medication delivery apparatus to deliver the pharmaceutical preparation to the patient according to a predetermined dose profile. The predetermined dose profile is designed to deliver a therapeutic dose of the pharmaceutical preparation to the patient over a predetermined infusion time in a manner which facilitates safe detection of an adverse reaction of the patient to the pharmaceutical preparation, or desensitization the patient to the pharmaceutical preparation, during a first stage of administering the therapeutic dose.

Disclosed herein are apparatuses and methods for a user-wearable infusion pump actuated with a shape memory alloy (SMA) wire. Embodiments enable an SMA wire driven infusion pump using a single length of SMA wire to provide multiple pulse sizes and corresponding medicament dispensing sizes. The multiple pulse sizes can include a larger pulse size for larger volumes to limit battery drain but smaller pulse sizes for precision of delivery.

A system for administering a medical fluid to a patient (P), comprises an infusion station (1) comprising a rack (10) and a control device (11), the rack (10) defining a multiplicity of slots (100), wherein the control device (11) is configured to synchronize reference patient data between infusion devices (2) attached to said multiplicity of slots (100), said reference patient data relating to a patient (P) to be administered with a medical fluid using the infusion station (1), and a new infusion device (2A) to be attached to one of said multiplicity of slots (100) of the rack (10). The control device (11) herein is configured, on the occasion of attaching the new infusion device (2A) to one of the multiplicity of slots (100) of the rack (10), to receive, from the new infusion device (2A), device patient data defined on the new infusion device (2A), and to update said reference patient data based on the device patient data dependent on an infusion status of the new infusion device (2A) and on an infusion status of the infusion station (1).

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

Various exemplary liquid drug pumps with a flexible drug reservoir are provided. In general, a pump includes a flexible reservoir configured to contain a liquid drug therein for delivery to a patient wearing the pump. The reservoir is configured to be filled with the drug from a drug storage container, which can either be external to the pump or disposed within the pump.

There is provided an infusion set capable of significantly reducing a period of time required for work of a worker during infusion. The infusion set includes a drip chamber, a tube which is connected to an outlet of the drip chamber, a roller clip which is provided in the tube, and an M clamp which is provided between the drip chamber and the roller clip in the tube and is used for storing liquid in the drip chamber. The tube has a first tube which can be mounted to an infusion pump device, a second tube which is connected to the outlet of the drip chamber and an inlet of the first tube, and a third tube which is connected to an outlet of the first tube. The M clamp is provided in the second tube, and the roller clip is provided in the third tube.

A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, a first flexible tube having a first lumen, a second flexible tube having a second lumen, and a valve assembly configured to selectively and reversibly compress the first flexible tube and the second flexible tube to open and close the first lumen and the second lumen. The valve assembly includes a first anvil moveable between a retracted position in which the first lumen is at least partially pen and an extended position in which the first anvil closes the first lumen, a second anvil moveable between a retracted position in which the second lumen is at least partially open and an extended position in which the second anvil closes the second lumen, and at least one eccentric cam rotatable to move the first anvil and the second anvil between the retracted and extended positions.

The M clamp is provided in the second tube, and the roller clip is provided in the third tube.

An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.
