Disclosed are examples of valve systems and methods of operating the respective valve systems. An example valve system may include a valve body, an inlet component, an outlet component and a valve tube. The valve body may include a first void and a second void. The inlet component may be coupled to the first void and the outlet component may be coupled to the second void. The valve tube may include a side port and may be positioned through the valve body and coupled to the first void, the inlet component, the second void, and the outlet component. Other valve system examples may include including a valve body, a first septum, a second septum, a first piston, a second piston and a tube. The disclosed methods describe the interaction of the respective components of the respective valve system example.

A pumping system comprising a pump comprising a door for access within a housing of the pump, a pump segment configured for conveying a fluid based on compression of the pump segment, a pump segment frame for preventing said pump segment from stretching, a visual placement indicator configured for facilitating in a proper placement of the pump segment frame in the housing, and a non-pinching valve configured to be disposed in the housing and to control a flow of the fluid without requiring pinching of a tube.

Priming systems and infusion assemblies are provided. For example, a priming system comprises a priming conduit having a priming portion and a pressure portion. The priming portion is in fluid communication with a first fluid source, with an inlet and an outlet for ingress and egress of a first fluid from the first fluid source. The pressure portion is in fluid communication with a second fluid source connected by a connector. Disposed within the priming conduit are a biasing member and a valve having an open position and a closed position. The biasing member is in operable communication with the valve to urge the valve into the closed position such that the valve defaults to the closed position. The open position allows the first fluid to flow from the inlet to the outlet and the closed position prevents the first fluid from flowing from the inlet to the outlet.

A needleless pain-free injection device according to the present disclosure includes a valve body, a valve member provided in an internal space of the valve body and airtightly sliding along the valve body, a liquefied gas container communicating with the internal space of the valve body and detachably coupled, at one end thereof, to the valve body, an operating knob provided on the exposed end of the valve member, a cylinder body coupled to one side of the valve body and having an internal space, a piston member provided such that one end thereof slides in the internal space of the cylinder body and having a piston rod, an injection unit provided with an injection piston rod coupled to the piston rod, and a gas passage forming means for selectively establishing and blocking the communication of the valve body and the cylinder body with outside air.

Flow controllers for intravenous (IV) tubing are provided. A flow controller may include a first structural member comprising a first outer surface and a first inner surface disposed at an angle to the first outer surface, a second structural member comprising a second outer surface parallel to the first outer surface and a second continuous inner surface parallel to the first inner surface, and a third structural member disposed on one of the first or second structural member and having a friction-reducing surface for at least a portion of a cavity disposed between the first and second structural members. The first structural member is linearly slidable along a length of the IV tubing disposed in the cavity to compress a portion of the IV tubing to control flow of a medical fluid through the IV tubing. Other flow controllers and IV sets that include a flow controller are also provided.

There is described a patch pump comprising a cartridge, a power source, a pump system, a drug delivery device and a control system configured to operate in particular the pump system and the drug delivery device. The pump system comprises, on the one hand, a pump having a pump housing containing a pump piston and a valve piston and, on the other hand, a pump drive comprising a piston motor and a valve motor for driving the pump piston and the valve piston independently from each other through a first and a second transmission. The drug delivery device comprises a transdermal delivery system having a needle actuation mechanism configured for transdermal insertion of a cannula.

Priming systems and infusion assemblies are provided. For example, a priming system comprises a priming conduit having a priming portion and a pressure portion. The priming portion is in fluid communication with a first fluid source, with an inlet and an outlet for ingress and egress of a first fluid from the first fluid source. The pressure portion is in fluid communication with a second fluid source connected by a connector. Disposed within the priming conduit are a biasing member and a valve having an open position and a closed position. The biasing member is in operable communication with the valve to urge the valve into the closed position such that the valve defaults to the closed position. The open position allows the first fluid to flow from the inlet to the outlet and the closed position prevents the first fluid from flowing from the inlet to the outlet.

A medical pump, comprising: a fluid housing having a plurality of intake openings, sealed by at least one intake valve, and an outlet opening sealed by an outlet valve; a piston which is sealing the fluid housing and connected to a drive mechanism, the drive mechanism pulls the piston to draw fluid from one of the plurality of intake openings and pushes the piston to discharge the fluid into the outlet opening; and a selecting valve enclosing at least two tubes, each providing fluid to one of the plurality of intake openings, wherein the selecting valve closes one of the at least two tubes while opening another of the at least two tubes.

The cleaning valves (or valves) of the current disclosure are generally single-use devices (SUDs) and therefore disposable. Reusing SUDs can be disadvantageous, as single-use devices are not designed to be reusable. Accordingly, valves (or valve assemblies) for medical devices, such as endoscopes, disclosed may be configured to transition from a first state to a second state in response to utilization of the valve, e.g., to control fluid flow through a valve well. The transition from the first state to the second state may prevent reuse of valves of the present disclosure. For instance, a lumen between first and second orifices in a valve stem may be blocked or disconnected.

The cleaning valves (or valves) of the current disclosure are generally single-use devices (SUDs) and therefore disposable. Reusing SUDs can be disadvantageous, as single-use devices are not designed to be reusable. Accordingly, valves for medical devices, such as endoscopes, disclosed may be configured to transition from a first state to a second state for indication of utilization of the valve, e.g., via exposure to a valve well. The transition from the first state to the second state may prevent reuse valves of the present disclosure. In embodiments, the valve may be made from a limited number of components and materials.
