A fluid conduit has a housing with a body forming an interior and a proximal cavity within the interior. The housing has an outlet and a fluid path extending between the cavity and outlet. The conduit also has an entry channel and a contact surface. The entry channel extends through the housing distal to the cavity and has a radial longitudinal axis. The entry channel is offset from the fluid path such that the radial longitudinal axis of the entry channel does not intersect a longitudinal axis of the fluid path. This offset causes fluid entering the interior of the housing via the entry channel to initiate a swirl-like motion within the interior. A portion of the contact surface is distal to the cavity and intersects the radial longitudinal axis. The surface directs a portion of the fluid proximally into the cavity.

FLOW METER HAVING A VALVE
20230398293 · 2023-12-14 ·

A flow control apparatus includes a body, a door, a drip chamber holster, and a valve. The door is pivotally coupled to the body. The drip chamber holster is coupled to one of the body or the door to retain a drip chamber. The valve is disposed within the body and is configured to receive a fluid line coupled to the drip chamber when the door is in an open position. The valve is operatively coupled to the door to secure the fluid line within the valve when the door is in a closed position.

Pinch clamp device

Pinch-style clamps can be designed for use in clamping or occluding plastic tubing, such as intravenous tubing. These pinch clamps can include a soft, polymer material applied to various surfaces of the pinch clamp to prevent abrasion or irritation to the patient, increase friction between the pinch clamp and the user operating said pinch clamp, increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended disengagement of the clamp, or increase friction between the outer surfaces of the tubing and the clamping surfaces of the clamp. Various features or components can be employed to prevent lateral disengagement of the pinch clamp. A pinch clamp may also be configured with rounded outer edges to enhance patient comfort.

Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.

A clamping device that is always capable of clamping a flexible tube in a good manner and assuredly closing the flexible tube without a large clamping force. A clamping device includes a holding member that holds a flexible tube in which a fluid is allowed to flow, and a clamping member that clamps and closes a clamping portion of the flexible tube that is held by the holding member. The clamping device further includes a heating device that heats the clamping portion of the flexible tube.

Liquid transfer device with telescopic vial adapter for use with infusion liquid container and discrete injection vial

A liquid transfer device is described. The liquid transfer device comprising a vial adapter comprising a puncturing cannula for puncturing an injection vial stopper, an IV spike and a substitute IV port holder for receiving a substitute IV port, and a flow control member port. The IV spike, the substitute IV port holder and the puncturing cannula are in flow communication with the flow control member port. The liquid transfer device comprising a flow control member sealingly inserted in the flow control member port. Rotation of the flow control member between a plurality of positions controls flow communication of the liquid transfer device, the positions comprising a mixing position for enabling flow communication between the IV spike and the puncturing cannula; and an administering position for enabling flow communication between the IV spike and the substitute IV port holder.

SYSTEM, METHOD, AND APPARATUS FOR MONITORING, REGULATING, OR CONTROLLING FLUID FLOW

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

FLUID TRANSFER CONNECTORS
20210138220 · 2021-05-13 ·

A fluid transfer connector comprises a medical standard connector part comprising a fluid transfer port, a connector part for flexible tubing, the connector part arranged to form a fluid connection with the fluid transfer port such that, in use, a fluid flow can pass between flexible tubing connected to the connector part and the fluid transfer port. The connector further comprises a moveable member arranged to interrupt the fluid flow in the flexible tubing when moved from a first position to a second position. The moveable member is further arranged to release a connection, in use, between the medical standard connector part and a corresponding adaptor part such as a female hub.
