Abstract:
A device for delivering fluid into the body is provided. The device may comprise a reservoir including at least one wall for retaining fluid and a plunger (400), wherein the plunger is articulated with a drive screw (300) having a distal end (304) that rotates within the plunger and displaces the plunger in a linear direction. The device may further comprise a reusable part having a motor, one or more gears and a receiving portion, and also a disposable part having a reservoir, a plunger and a drive screw having a proximal end capable of engaging with the receiving portion upon connecting the reusable part and the disposable part
Abstract:
Devices and methods for delivering therapeutic fluid to a patient's body are described. The devices may comprise a dispensing unit having a reservoir, a driving mechanism having a movable member for delivering therapeutic fluid to a patient's body, at least one sensor for sensing a relative position of the movable member and generating a signal, and a processor for controlling the driving mechanism to deliver an amount of therapeutic fluid that compensates for a change in the flow of the therapeutic fluid occurring during fluid delivery. The methods may be implemented by operating the driving mechanism, receiving a signal based on the position of the movable member, determining an amount of therapeutic fluid to deliver, and controlling the driving mechanism to deliver an amount of fluid that compensates for a change in flow occurring during fluid delivery.
Abstract:
Embodiments of the present disclosure are directed to a skin adherable device for delivering therapeutic fluid into a body of a patient. In some embodiments, the device includes a monitoring apparatus, a pump, and a tip for delivering the therapeutic fluid into the body of the patient and for monitoring bodily analyte in the body of the patient. The pump may continuously deliver the therapeutic fluid to the body of the patient and the monitoring apparatus may continuously monitor bodily analytes of the patient.
Abstract:
A volume of an analyte-enriched fluid can be withdrawn out of a user's subcutaneous compartment using a patch unit that includes a reversible pumping mechanism. The volume can be withdrawn out of the body and into the patch unit through a cannula inserted into the subcutaneous compartment so that an analyte concentration in the volume can be measured using a sensing element within the patch unit. After analyte concentration analysis, at least the volume can be delivered back into the subcutaneous compartment by operating the pumping mechanism in a forward direction. biologically compatible fluid can optionally be pumped into the subcutaneous compartment from a reservoir in the patch unit and then allowed to partially or completely equilibrate with the analyte concentration in the interstitial fluid of the subcutaneous compartment via a permeable or semi-permeable cannula surface before being drawn back into the patch unit for analysis. Related systems, apparatus, methods, and/or articles are also described.
Abstract:
A portable therapeutic apparatus and a method for controlling the apparatus are provided. In one aspect the apparatus and the method can be implemented using a patch unit (100, 200) removably attachable to a cradle unit (20), said cradle unit removably attachable to the body of the patient; a position detector (1000) comprising a patch portion (900) and a cradle portion (800), said patch portion coupled to the patch unit, said cradle portion coupled to the cradle unit; a processor adapted for receiving a position indication signal from the at least one position detector, said position indication signal corresponding to a physical proximity of the patch portion to the cradle portion, and, wherein the portable therapeutic apparatus is adapted for at least one therapeutic function selected from the group consisting of delivering a therapeutic fluid into the body of the patient and sensing a bodily analyte.
Abstract:
Methods, systems, and apparatuses for delivering therapeutic fluid to a user are disclosed. The apparatus includes a pump mechanism for pumping therapeutic fluid to the user having a reusable part which includes a housing and a disposable part configured to be inserted into the housing of the reusable part and to be connected with the reusable part. The connection of the reusable part and the disposable part enables operation of the pump mechanism and disconnection of the reusable part and the disposable part disables operation of the pump mechanism.
Abstract:
Disclosed is a portable ambulatory fluid delivery device. The device includes a dispensing unit to dispense therapeutic fluid, the dispensing unit including one or more rechargeable batteries, a housing to retain the one or more rechargeable batteries, a reservoir to contain the therapeutic fluid, a driving mechanism to cause delivery of the therapeutic fluid from the reservoir to a user's body, and at least one electrical connector to be coupled to a recharging unit to direct electrical power received from the recharging unit to recharge the one or more rechargeable batteries. At least a portion of the housing is securable to a skin of the user.
Abstract:
Medical devices and methods for delivering therapeutic fluids transcutaneously to a body of a patient via a fluid delivery device and an adapter is provided. A Luer slip connector is provided at a first connecting end of the adapter. A therapeutic fluid container is connected with the second connecting end such that the container's neck is received in the second connecting end and a hollow penetrating member provided in the adapter punctures the septum of the container to admit the therapeutic fluid into a needle-less syringe from the container. After, fluid emerges from the tip of the penetrating member, the second connecting end of the adapter is attached to the fluid delivery device, thereby filling the reservoir with the fluid and pushing the syringe plunger forward to inject fluid into reservoir.
Abstract:
Disclosed is a fluid dispensing device that includes at least one reservoir to hold the therapeutic fluid, at least one other unit requiring communication with ambient air, at least partly, to operate, and at least one housing defining an interior to retain the at least one reservoir and the at least one other unit. The at least one housing has at least one vent port formed on one or more of its walls. The at least one vent port is adapted to direct or communicate air to maintain pressure equilibrium between the air pressure in the interior of the at least one housing and the ambient air pressure outside the at least one housing, and provide communication with the ambient air to the at least one other unit requiring air to enable operation of the at least one other unit.
Abstract:
Disclosed is an ambulatory therapeutic fluid delivery device (10). The device includes at least one housing (200) connectable to a cannula (250), the at least one housing retaining a reservoir (220) to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism (150) to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.
