A fluid container is encompassed by a custom fluid container pressure sleeve, which is configured to wrap around, connect and form to the malleable fluid container such that, when the fluid container pressure sleeve is inflated with a gas, the fluid container pressure sleeve applies an inward directional pressure to the malleable fluid container from an exterior of the malleable fluid container to compress the malleable fluid container. A pump connected to the fluid container pressure sleeve is activated to provide the gas to the fluid container pressure sleeve to compress the malleable fluid container and direct a fluid (e.g., the blood product) within the malleable fluid container toward and through a connected infusion tubing

The invention provides a fluid management system (1) for providing fluid from a fluid source (20) to the body of a patient. The fluid management system (1) includes a compressible chamber (10). A fluid conduit (30) is in fluid communication with the fluid source (20) and with an interior of the compressible chamber (10). A bypass conduit (40) has an inlet end (43) in fluid communication with the fluid source (20) and an outlet end (44) for providing fluid to a trocar (70). The bypass conduit 40 passes either through or around the compressible chamber (10). A first one way valve (80) can admit fluid from the fluid conduit (30) into the interior of the compressible chamber (10). A second one way valve (90) can admit fluid within the interior of the compressible chamber (10) into the bypass conduit (40). A portion (46) of the bypass conduit (40) upstream of the second one way valve (90) is collapsible under the force of selectively applied external pressure when the compressible chamber (10) is at least partially filled with fluid from the fluid source (20), so as to selectively close off the bypass conduit (40) upstream of the second one way valve (90).

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method involves operating an infusion device to deliver fluid to a user in accordance with a first operating mode of a plurality of operating modes, obtaining operational information pertaining to the first operating mode, and obtaining clinical information pertaining to the user. A destination operating mode of the plurality of operating modes is determined based at least in part on the operational information and the clinical information, and the infusion device is operated to deliver the fluid in accordance with the destination operating mode in a manner that is influenced by at least a portion of the operational information pertaining to the first operating mode.

Disclosed is an ambulatory therapeutic fluid delivery device. The device includes at least one housing connectable to a cannula, the at least one housing retaining a reservoir to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism 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.

Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes a combined piston pump and rotatable valve. The piston pump is configured to prevent partial dosing of a bolus dose.

A gear-driven infusion assembly is provided which has a housing, a gear assembly coupled to the housing, a shuttle assembly slidably coupled to the housing and operably coupled to the gear assembly, and a tube enclosure connected to the housing. The tube enclosure is configured to house a primary drug closure. The gear assembly includes a spool assembly having a pinion gear and a drive spool. When the spring rotates the drive spool, the drive spool drives the pinion gear, and the gear assembly drives the shuttle assembly. When the gear assembly drives the shuttle assembly, the shuttle assembly slides longitudinally along the housing. The gear assembly may be spring driven such that a spring rotates the pinion gear about the drive spool. The primary drug closure may be a syringe. An overspeed protection device is also provided which has a spool assembly including a drive spool having a plurality of cams, a spring, and a pinion gear with spiral cam surfaces.

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method involves operating an infusion device to deliver fluid to a user in accordance with a first operating mode of a plurality of operating modes, obtaining operational information pertaining to the first operating mode, and obtaining clinical information pertaining to the user. A destination operating mode of the plurality of operating modes is determined based at least in part on the operational information and the clinical information, and the infusion device is operated to deliver the fluid in accordance with the destination operating mode in a manner that is influenced by at least a portion of the operational information pertaining to the first operating mode.

Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes an inlet check valve, a first outlet check valve downstream of the inlet check valve, and a piston pump disposed between the inlet check valve and the first outlet check valve. The piston pump is configured to prevent partial dosing of a bolus dose.

The present invention relates to a medicament delivery device comprising a housing, a compartment inside said housing for positioning a medicament container, an injection needle arranged to said housing, being connectable to said medicament container for delivering a dose of medicament, a manually operated activation mechanism for activating said device, an actuation mechanism operably connected to said activation mechanism and arranged to, upon activation of said activation mechanism, extend said injection needle from a first position inside said housing to a second position wherein a penetration of a patient is performed, a plunger rod arranged in said housing capable of acting on said medicament container for delivering a dose of medicament through said injection needle, a driver capable of acting on said plunger rod for delivering a dose of medicament. The invention is characterised in that said device comprises a needle cover operably arranged in said housing from a first position inside said housing to a second extended position outside said housing for shielding said injection needle when said injection needle is in said second position.

A syringe pump is provided. The syringe pump includes a pump body, a control system, a transmission mechanism, and a propulsion mechanism. The transmission mechanism includes a bracket, a propulsion driving motor, a screw rod, a sliding seat, a half nut, and a clutch driving assembly. The propulsion driving motor configured to drive the screw rod to rotate, the clutch driving assembly is disposed on the sliding seat, and configured to drive the half nut and the screw rod to be engaged and disengaged from each other. The propulsion mechanism includes a connecting rod, a pushing block, a pressure sensing assembly, and a clutch switch. The pressure sensing assembly is disposed on the pushing block and configured to detect pressure of a piston rod of a syringe. The clutch switch is disposed on the pushing block and electrically connected to the clutch driving assembly.
