A clamp includes a fixed portion including an upper portion on which a medical tube is to be placed; a movable portion that faces the fixed portion; a curved portion that connects the fixed portion and the movable portion and is configured to elastically deform; a pressing portion that protrudes from the movable portion toward the fixed portion, and presses and closes the medical tube; a pair of sidewalls that protrude from both side portions of the fixed portion in a wall shape, respectively, and are configured to prevent lateral displacement of the medical tube; and a standing portion that faces the curved portion. The standing portion is provided with a lateral displacement prevention mechanism that prevents sideward deformation of the movable portion when the movable portion is pressed.

A drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, a flow rate sensor, and a flow controller. The delivery container further includes an outlet port and is constructed from a resilient material. The container body is adapted to exert an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user. The flow sensor senses a flow rate of the drug within the supply line. The flow controller is configured to regulate a flow rate of the drug; the flow controller includes a supply line restrictor and a controller for adjusting the supply line restrictor between at least two settings.

A roller clamp assembly for adjusting the fluid flow rate in a connector tube of an infusion set is provided. The roller clamp assembly includes a housing to receive the connector tube, a plate slideably engaged with the housing and configured to rapidly compress the connector tube to provide a coarse fluid flow adjustment, and a roller wheel moveable engaged with the housing and configured to provide a gradual fluid flow adjustment. The plate may be a slide plate received by grooves in an exterior wall of the housing and that moves orthogonally to the connector tube, or the plate may be a shim plate that moves along an interior wall of the housing in parallel to the connector tube. Infusion sets and methods of adjusting fluid flow rates are also provided.

Enteral feeding pump systems valves assemblies therefor and related fluid flow control methods. The system includes a disposable fluid delivery set with an integral peristaltic tube section and an enteral feeding pump. The system may also include a pinching mechanism for regulating the flow of nutrient formula or water out of the fluid delivery set. Also disclosed is a flow selector valve assembly for an enteral feeding pump system, the valve assembly including a tube adapter having two input flexible tubing channels and one output tubing channel and being configured to position the flexible tubing channels in relation with a receiver. The receiver has an eccentric bearing that is moveable between a first position in which neither of the input flexible tubing channels is compressed, and a second position in which the eccentric bearing compresses one of the input flexible tubing channels therein to prevent flow therethrough.

A roller clamp assembly for adjusting the fluid flow rate in a flexible infusion tube is provided. The roller clamp assembly includes a housing to receive the flexible tube, a plate slideably engaged with the housing and configured to rapidly compress the flexible tube to provide a coarse fluid flow adjustment, and a roller wheel moveable engaged with the housing and configured to provide a gradual fluid flow adjustment. The plate may be a slide plate received by grooves in an exterior wall of the housing, where the plate moves orthogonally to the flexible tube, or the plate may be a shim plate that moves along an interior wall of the housing in parallel to the flexible tube. Infusion sets and methods of adjusting fluid flow rates are also provided.

An apparatus may be used with an elongate member that includes an engagement member, a hollow shaft, a compression member, a compression element, and a resilient gripping member. The hollow shaft extends from the engagement member along a longitudinal axis. The compression member is slidably disposed over the hollow shaft. The hollow shaft is disposed over the resilient gripping member and supports the compression element. The compression member has a conical inner surface including a detent feature. The conical inner surface is configured to urge the compression element radially inwards as the collar advances from the unlocked position toward the locked position where the detent feature retains the compression element. The compression element deforms the resilient gripping member radially inwards to grip the elongate member and prevents translation of the elongate member. When unlocked, the resilient gripping member moves radially away from the elongate member allowing translation.

Roller clamp for regulating the flow of a fluid through an elastically deformable tubing including a generally channel-shaped body whose bottom wall has a clamping surface with a longitudinal groove with a cross-section decreasingly variable from an initial end towards a terminal end. The longitudinal groove is arranged asymmetrically with respect to the lateral walls of the body.

A circular roller clamp assembly includes a semi-circular housing configured to receive a portion of an IV tube, a motor and a motor arm coupled to the motor. A roller is coupled to the roller arm, the roller movably received by a guide groove disposed in the semi-circular housing. A flow rate of fluid flowing through the IV tube is regulated based on roller impingement of the IV tube against a tube channel in the guide groove via circumferential movement of the roller along the guide groove. IV sets with circular roller clamp assemblies and methods of operating circular roller clamp assemblies are also provided.

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.

A clamp arrangement for retaining a flexible tube (18) during operation of a roller pump (10) for pumping fluid, the clamp arrangement comprising a pair of rotatable bobbins (24A, 24B, 26A, 26B) mounted adjacent to each other. Each bobbin (24A, 24B, 26A, 26B) has a tapered groove (30), formed partially around a cylindrical surface of the bobbin (24A, 24B, 26A, 26B), and counter rotation of the bobbins (24A, 24B, 26A, 26B) clamps the tube 18 between the bobbins (24A, 24B, 26A, 26B) in the tapered grooves (30). The clamp arrangement allows tubes of different shapes and diameters to be securely held without overly deforming the tube.
