A flow regulator device and an associated method of using the device to constrict the flow of fluid through an intravenous line is disclosed. The device comprises a first component pivotally attached to a second component by a hinge. The first and second components are coupleable together into a closed book-like position for enshrouding an intravenous transfer line within a cylindrical tubing channel traversing along the device. A semi-elliptical pinch-off wheel is attached to the device so that...

A medical fluid suctioning device for selectively applying varied levels of suction pressure at a device-tissue interface includes a direct "trumpet"-type control mechanism in conjunction with a "venturi"-type control. A valve manifold is adapted to couple a vent pathway and a suction pathway simultaneously to the vacuum conduit adapted for connection to a vacuum source. The amount of resistance to flow due to vacuum pressure is adjusted simultaneously in both the vent pathway and the suction pa...

A transportable apparatus for treating Meniere's disease comprises electronically controlled pressure variation unit housed in an inner casing which is partially enclosed by an outer casing provided with an opening covered by a removable cover. A storage compartment is disposed between the casings to receive a flexible tube provided with an ear plug. The flexible tube is connected to the pressure variation unit. The storage compartment surrounds a first portion of the inner casing in which the f...

An adapter is connected to a probe tube of a PEG probe that is already in place, the probe tube being cut off above the abdominal wall of the patient. The adapter comprises an outer retaining element, which is supported on the abdominal wall, and comprises structure for fastening the proximal end of the PEG probe, and structure for connecting a delivery line to the flow channel. A shut-off element having a rotatable or displaceable closing body is provided for closing the PEG probe. The adapter ...

A hand-operated syringe for injecting a liquid under high pressure. The syringe has an elongated barrel with proximal and distal ends, the barrel having opposing finger grips at its proximal end with each finger grip having a proximal inner portion defining a most proximal pressure point closely adjacent the barrel, the pressure points defining a plane substantially perpendicular to the barrel's axis. A plunger is received in the barrel and has a proximal end that includes a pressure surface ada...

A device for warming fluids being administered intravenously to a patient. The heating assembly comprising a warming pouch is wrapped and secured around a tube through which fluid is intravenously provided to the patient.

The positive flow needleless connector has a cannula slideably mounted within a tubular housing. A sleeve-like septum seals the cannula from an outside environment while also sealing an internal chamber of the cannula from a flow path in a male luer housing. Movement of the cannula from an extended position to a retracted position against the force of a spring exposes a second inlet of the cannula to the flow path of the male luer housing to permit flow therebetween. During disconnect, the inlet...

Valved ports for accessing blood vessels and other body lumens include a lock mechanism which locks the valve fully open when a needle or other access tube is placed into the port. The lock mechanism includes a latch typically comprising one or more laterally deflectable elements, such as a pair of opposed balls. The deflected elements are pushed outwardly by the needle to engage a recess in the port which locks the valve open until the needle is removed.

A tubular medical set as main blood flow tubing, a connected, flexible branch tube, a flow restriction device to suppress pressure pulses. The device is positioned to control flow through the branch tube. The flow restriction device permits substantially free, unhindered flow from the branch tube to the main blood flow tubing, while significantly restricting, but not completely blocking, flow from the main blood flow tubing to the branch tube.

An implantable, time-released substance delivery device includes a casing having an exterior surface, and a number of pores disposed on the exterior surface of the casing. The time-released substance delivery device further has an interior chamber disposed within the casing, and a number of excretion tubes disposed within the casing. Each of the excretion tubes fluidly connects the interior chamber to one of the pores.
