A clamp apparatus is disclosed that includes a body, first and second actuators, first, second, third and fourth gear sets, first and second movable grippers, and at least one leaf spring. The first gear set is coupled to the first actuator and the second gear set is coupled to the second actuator. The first gear set engages the second gear set. The first and second movable grippers are each operatively coupled to the body. The third gear set is coupled to the first movable gripper and the fourth gear set is coupled to the second movable gripper. The third gear set operatively engages the fourth gear set. The leaf spring engages with the third gear set and the fourth gear set to urge the first movable gripper and the second movable gripper toward a clamped position.

The present invention relates to a flow rate regulator for intravenous injection, capable of preventing an operating roller from rotating, where a flow rate of an intravenous fluid is adjusted by the operating roller, to keep the flow rate of the intravenous fluid from varying, the flow rate regulator including: a body having a space portion penetratedly formed thereinto in an up and down direction to connect an infusion tube thereto and a roller connection hole formed on the front surface thereof; the operating roller fitted to the roller connection hole of the body, moving up and down along the roller connection hole, and pressurizing the infusion tube thereagainst to allow the flow rate of the intravenous fluid to be regulated; and a roller holder connected to the body to which the operating roller is fitted and supporting the operating roller thereagainst to prevent the operating roller from moving.

Devices, systems and methods are used to decouple proximal movement of a catheter supply lead or tubing from the tissue-embedded catheter. A catheter decoupling device comprises a catheter hub, sled and track, wherein the hub comprises a proximal end configured to receive a catheter fluid supply device, and a distal end configured to receive a catheter, the sled receives and retains the hub, the track receives and retains the hub; and, the hub has a limited range of back-and-forth motion relative to the track.

A connector includes: a male connector portion; a first female connector portion; and a second female connector portion. The connector defines a flow path therein. The male connector portion is shaped to be connectable to a medical device female connector portion that is equal in shape to the first female connector portion. The male connector portion is shaped to not be connectable to a medical device female connector portion that is equal in shape to the second female connector portion.

A universal flow limiter assembly includes a body configured to receive a portion of an IV tube, where the body includes two opposing side beams, a hinge portion disposed at a first end of the body, a control portion disposed at a second end of the body, a groove defined between the side beams and disposed between the hinge portion and the control portion and a control knob. The universal flow limiter assembly is configured to regulate a flow rate of fluid flowing through the IV tube based on rotation of the control knob. IV sets with universal flow limiter assemblies and methods of operating universal flow limiter assemblies are also provided.

A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.

An intravenous (IV) set system comprising a primary IV set defining a primary flow line of the IV set system. The primary flow line can include multiple access points along its length and feeds to a merging fluid pathway proximate to the distal terminus of the primary IV set. At least one secondary IV set with corresponding flow lines can be separably joined to the primary IV set to cause the secondary flow lines to be in fluid communication with the primary flow line. At least one of the IV sets can have a unique set of uniform marking indicia to facilitate rapid identification of the IV sets from other IV sets within the IV set system. Such marked and identified primary and/or secondary IV sets can be allocated to specific medical functions and/or can be for use by specific medical personnel to thereby minimize risk of error in administration of an IV to a patient. The IV set system can further comprise a merging fluid pathway about a primary IV set.

Ambulatory infusion pumps, medicament reservoirs, and medicament sealing assemblies, including a variety of trocar seal assemblies and fill plug seal assemblies, plus related components, as well as component combinations and related methods.

The present invention is provided to suppress occurrence of free flow. An infusion pump includes: a sliding clamp closing and releasing an infusion tube; a pump body including a tube attachment portion to which the infusion tube is to be attached detachably and forcibly transferring liquid in the infusion tube; and a door pivotably supported by the pump body so that the tube attachment portion is openable and closable by the door. The pump body includes: a clamp attachment portion into which the sliding clamp having the infusion tube set therein is to be inserted and set; and a release operator being operated in the clamp attachment portion to transfer the sliding clamp from a close mode to a release mode, the release operator being configured to be locked, in response to opening movement of the door, so that the release operator is inoperable for releasing, and to be unlocked in response to closing movement of the door.
