An infusion pump device comprises a pumping means having a fluid inlet which is adapted to be connected to a vial for taking fluid out of the vial and a fluid outlet which is adapted to be connected to an infusion catheter, and a controlling means which is adapted to be connected to the vial and to control pressure inside the vial so as to avoid occurrence of underpressure at the fluid inlet.

The problem of infusing air into IV tubing and into a patient from a IV fluid bag inside a pressure infusion cuff is solved by collar embodiments that inhibit the air from being forced into the IV tubing. A collar can include one or more curved arms that create a channel in which that part of the fluid bag is protected against being squeezed by a pressure infusion cuff. A collar allows the fluid bag to be squeezed by the pressure infusion cuff until such time that the fluid level is sufficiently reduced that the collar can inhibit further pressure on the fluid bag by the pressure infusion cuff. Also disclosed is a fluid bag and a pressure infusion cuff that are modified to have a collar incorporated therewith.

An apparatus having an outer wall that encompasses an interior chamber that holds a predetermined volume of fluid and gas where the gas rises to one end of the interior chamber and the fluid flows to the other end of the interior chamber. The apparatus also has an inlet port that allows for fluid to ingress into the interior chamber and an outlet port that allows for fluid to egress out of the interior chamber.

A liquid dispensing port (10) comprising: a distal end (12) and a proximal end (14), wherein the distal end (12) is received in a container/bottle (16), an infusion tube (18) received in the proximal end (14); a holding rim (20) provided in between the proximal (14) and distal (12) end; axially extending openings (22) and (24) formed in the liquid dispensing port (10); an air vent (26) extending axially parallel to the openings (22) and (24) is provided in the port (10) which facilitates the passage of liquid from the container (16) through the tube (18).

An apparatus and method for delivering fluid from a syringe to a subject using a pumping device of a flow control apparatus. The method includes locating the flow control apparatus on a horizontal support surface. Providing the syringe with a volume of fluid including a total amount of preferred nutrient and an amount of non-preferred nutrient liquid. Mounting the syringe relative to the flow control apparatus whereby the syringe is oriented in a generally vertical orientation such that an outlet of the syringe faces upward. Initiating operation of the pumping device to draw the fluid from the syringe for a duration of time to preferentially deliver at least a portion of the total amount of preferred nutrient in the fluid to the subject.

Disclosed is a fluid dispensing device that includes at least one reservoir to hold the therapeutic fluid, at least one other unit requiring communication with ambient air, at least partly, to operate, and at least one housing defining an interior to retain the at least one reservoir and the at least one other unit. The at least one housing has at least one vent port formed on one or more of its walls. The at least one vent port is adapted to direct or communicate air to maintain pressure equilibrium between the air pressure in the interior of the at least one housing and the ambient air pressure outside the at least one housing, and provide communication with the ambient air to the at least one other unit requiring air to enable operation of the at least one other unit.

An apparatus for automatically setting and maintaining a fluid level in a drip chamber is described. A drip chamber according to one embodiment includes a drip chamber body defining an internal volume, an inlet tube configured for dripping fluid into the interior of the drip chamber, an outlet tube in fluid communication with the interior of the drip chamber, and an air vent configured to automatically prevent the venting of air out of the interior of the drip chamber if the fluid filling the interior of the drip chamber is above a predetermined fill level, and to automatically vent air out of the drip chamber when the fluid falls below the predetermined fill level, the predetermined fill level corresponding to a volume less than the internal volume of the drip chamber.

The present invention is comprised in the sector of the industry dedicated to the manufacturing of medical supplies, particularly focusing on containers for the artificial feeding of enteral feeding products through a tube. In particular, the present invention relates to a closure cap for a container for supplying enteral feeding products by means of the drive of a drive head, and it also relates to a drive head that can be coupled to the cap for driving the supply of enteral feeding products contained in a container, and in turn to a drive system formed by said cap and drive head.

A fluid path set for a fluid delivery system includes a tube coil that is designed to optimally position one or more volumes of a pharmaceutical within an ionization chamber to measure and prepare a pharmaceutical dose for administration to a patient. Methods for priming at least a portion of the fluid path set include placing a tubing section of the fluid path set in fluid connection with a source of a radiopharmaceutical, and placing the tube coil within a dose calibrator of the fluid delivery system. A volume of the radiopharmaceutical may be pumped through the tube coil, the tubing section, and an additional tubing section, and the dose calibrator may be monitored to determine if a measured activity level is substantially equal to or above a predetermined activity level, and if so, it may be concluded that the tubing section of the fluid path set has been primed.
