The invention discloses an integrated drug infusion device, comprising: infusion unit configured to deliver drugs; program unit comprising input end and output end, and the input end comprises a plurality of electrically connective regions for receiving signals of analyte data in the body fluid, after the output end is electrically connected to the infusion unit, according to the received signals of analyte data in the body fluid, the program unit controls whether the infusion unit delivers drugs; an infusion cannula with conductive area, the infusion cannula is the drug infusion channel; and a plurality of electrodes for detecting analyte data in body fluid, the electrode comprising conductive-area electrode and cannula-wall electrode, the conductive area of the infusion cannula being at least as a conductive-area electrode, and one or more cannula-wall electrodes being located on/in the wall of the infusion cannula. It takes only one insertion to perform both analyte detection and drug infusion.

A novel embodiment of a pump system, for example, of the type that would be used in a wearable drug delivery system, comprises dual linear-actuated plungers disposed in a pump chamber. The plungers are coupled to a leadscrew having both left-hand and right-hand threads such that rotation of leadscrew in a first direction moves the plungers together and rotation of leadscrew in a second, opposite direction moves the plungers apart. Movement of the plungers away from each other draws one or more doses of a liquid drug from a reservoir into the pump chamber, while movement of the plungers together forces liquid drug to a patient interface for delivery to the patient.

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

A drug infusion device with multiple infusion modes, includes: a reservoir (110), a piston (120) and a screw (130), the piston (120) is arranged in the reservoir (110); a driving module at least includes a first driving unit and a second driving unit that cooperate with each other, the second driving unit drives the screw (130) forward; a power module connected to the first driving unit; and a control module (101), connected to the power module, controls the power module to apply different driving powers to the first driving unit, making the first driving unit have a variety of different operating modes, thereby making the infusion device have various different infusion increments or infusion rates. The user or the system can flexibly select the infusion mode, which enhances the user experience.

Portable pump (11) for drug infusion through a syringe (SR) removably engaged in the pump, said pump comprising an electromechanical unit (13) having a rod (15) which is longitudinally slidable within a guide member (17) and capable of exerting an axial thrust onto the plunger (SF) of the syringe engaged in the pump, wherein said rod (15) and said guide member (17) have a non-circular cross-section, whereby rotation of the rod (15) relative to the guide member (17) is prevented.

A nerve cuff for establishing a nerve block on a nerve can have a cuff body with a channel for receiving a nerve, a reservoir for holding a drug, and an elongate opening slit extending the length of the cuff body that can be opened to provide access to the channel and can be closed to enclose the cuff body around the nerve. The nerve cuff can also include an electrode for detecting and measuring electrical signals generated by the nerve. A controller can be used to control delivery of the drug based on the electrical signals generated by the nerve.

Shell (11) for a portable electromechanical apparatus for drug infusion, comprising an outer casing (13) and a support structure (15) housed within the casing (13), wherein said casing (13) has a monolithic ring shape and is entirely made of plastics, and wherein said support structure (15) is at least partially made of metal.

Delivery pumps for providing a bolus or blenderized diet to enterally fed mammals are provided. A delivery pump according to the present disclosure is manually operated, and does not require mechanically powered operation. A delivery pump according to the present disclosure also has a size sufficient to contain an entire bolus or blenderized diet feeding, and is shaped to allow filling of the reservoir with a bolus or blenderized diet by a user. The present disclosure also includes a method of providing a bolus or blenderized diet to a mammal.

A method of performing an intravenous drip injection includes a first step, a second step, a third step and a fourth step. A first step includes starting dosing an infusion solution containing a predetermined component by the intravenous drip injection to a dosing recipient. A second step includes extracting a body fluid from the dosing recipient being dosed with the infusion solution. A third step includes measuring a concentration of the predetermined component in the extracted body fluid. A fourth step includes varying the concentration of the predetermined component in the infusion solution, corresponding to the concentration of the predetermined component in the body fluid.

A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.
