The invention relates to an apparatus comprising an electromechanical device, a control unit, a main control unit and a motion detector, wherein said control unit is configured to control said electromechanical device. The invention also relates to a method for operating an apparatus with a main control unit, a control unit and an electromechanical device. The technical problem of providing an apparatus with an electromechanical device, the reliability of which is improved, is solved by an apparatus wherein the main control unit is configured to provide information to the control unit. The motion detector and the main control unit are configured such that information about the movement of the electromechanical device is provided by the motion detector at least to the main control unit. The technical problem is also solved by a method for operating an apparatus, in particular an apparatus or medical device according to the invention.

A fluid path set including a multi-patient use section adapted for connection with a pump device and a source of injection fluid, and a per-patient use section adapted for removable fluid communication with the multi-patient use section. The per-patient use section includes a pressure isolation mechanism having a first port adapted for connection to the pump device via the multi-patient use section, a second port adapted for connection to a patient, and a pressure isolation port adapted for connection to a source of medical fluid via the multi-patient use section. The per-patient use section includes a valve member biased to a normally open position permitting fluid communication between the first port, the second port, and the pressure isolation port, and movable to a closed position to close the pressure isolation port when fluid pressure reaches a predetermined pressure level sufficient to overcome a biasing force applied to the valve member.

Systems for predicting a drug delivery profile as described herein include at least one drug pump and/or a controllable valve that produce a drug flow and dispense at least a first drug. The system also includes at least one carrier fluid pump and/or another controllable valve that produces a carrier fluid flow, a flow junction structure configured to receive the drug flow and the carrier fluid flow to produce a mixed flow, and a fluid path for carrying the mixed flow between the flow junction structure and a delivery point. The system further includes a processing device configured to predict the drug delivery profile at the delivery point based on determining a predicted time variation of drug concentration at the delivery point using at least a model of the mixed flow. The model includes a plurality of parameters related to propagation of the mixed flow through the fluid path.

A valve and a method for administering a plurality of drug fluids to a patient are disclosed. For each drug fluid, the valve may be rotated into a selected drug position associated with the drug fluid. With the valve being in the selected drug position, a backpriming may be performed of a connector line of a drug container containing the drug fluid. Thereafter, the drug fluid may be administered with the valve being in the same selected drug position. Thereafter, the valve may be flushed, optionally while maintaining the same selected valve position.

A patient care system is configured for infusing fluid to a patient. The system includes a plurality of modular fluid infusion pumps that each has a connector for connecting to a modular programming unit or to one another. Systems and methods are configured for verifying that the connectors are reliably performing their functions or communicatively connecting the pumps to one another or to the programming unit.

The systems, methods and articles described herein are directed to at least one pressure sensor along a downstream fluid line which senses fluid pressure and assists an occlusion detection feature in determining the presence of occlusions in the downstream fluid line. In addition, the system can dynamically adapt the occlusion detection feature based on a delivery of fluid, such as a bolus, in order to prevent the system from creating a false alarm regarding an occlusion of the downstream fluid line.

Infusion pump control unit keypad assemblies are provided, and include a cover assembly having an outer surface and an inner surface and a perimeter gasket disposed within a raised perimeter on the outer surface of the cover assembly. A lens and a circuit assembly are coupled to the outer surface of the cover assembly. A switch assembly is coupled to the circuit assembly, a shield assembly is coupled to the switch assembly, a light assembly is coupled to the shield assembly and an overlay assembly is coupled to the light assembly. Methods of making infusion pump control unit keypad assemblies are also provided.

A bolus control device for use with an injection device, the bolus control device including a valve body having a proximal end opposite a distal end. The valve body defines a fluid channel therethrough to allow a passage of medical fluid from the proximal end to the distal end. A connector is provided at the proximal end and configured for connecting to a fluid inlet line. A connector subassembly is provided at the distal end and configured for connecting to a fluid outlet line. A compressible check valve is disposed within the fluid channel, such that the compressible check valve is adjustable to control a cracking pressure at which the compressible check valve closes.

A medicinal fluid pooling device may be used to pool multiple containers of medicinal fluid to facilitate administration of the medicinal fluid to a patient. A medicinal pooling device may include spikes covered by spike sheaths which are pierced when a container of medicinal fluid is inserted into the medicinal pooling device. The medicinal pooling device may also include a cover configured to cover the spikes. The medicinal pooling device may also include a fluidic interface which may be used to fluidly connect the medicinal pooling device to an infusion pump or syringe.

In a chemical liquid injection conduit, there is a need to prevent a backflow of body fluid of a subject reaching the inside of a common conduit portion. This is solved by the chemical liquid injecting apparatus that includes: a common conduit portion that flows a chemical liquid from a chemical liquid injector to a replaceable conduit portion; a control device that controls the chemical liquid injector; and a flow blocking unit that is arranged inside the replaceable conduit or in a conduit of a boundary portion between the replaceable conduit and the common conduit portion, and by receiving a command from the control device, is switchable between an open state allowing a flow of the chemical liquid and a closed state blocking a flow of the chemical liquid.
