An apparatus, method, and article of manufacture for transferring fluid contained in a syringe. The apparatus includes an airlock component having a cylindrical body with a first end, a second end, and a hollow tube disposed between the first end and the second end. An annular opening is located at the first end of the cylindrical body. The hollow tube includes a gas inlet aperture and a gas outlet aperture. The hollow tube also includes an inwardly-facing airtight material coupled to the interior surface of the hollow tube, and a septum coupled to the second end of the cylindrical body. The method includes transferring fluid from one container to a second container using the apparatus. The article of manufacture includes the apparatus, a syringe, and a needle.

A device and method for measuring a volume of liquid expelled from a syringe is provided. The device generally includes a syringe barrel, a plunger actuated with a plunger rod, and a sensor. The sensor may include two ports with one port being in fluid communication with a source of fluid external to the syringe barrel, while the second port is in fluid communication either with a proximal end portion of the syringe barrel or a hollow plunger rod having a first end closed by the plunger. The method may include expelling liquid from the syringe; detecting and recording differential pressure with the sensor over time; and calculating the volume of liquid expelled from the syringe from the recorded differential pressure over time.

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.

An injection device is provided for delivering a liquid medicament. The injection device includes a housing with a first chamber for storing a supply of the medicament. The first chamber and a second chamber are coupled within the housing. The second chamber is in fluid communication with the first chamber. The system also includes an outlet port for dispensing the medicament outside the housing. The outlet port is coupled to the housing and in fluid communication with one of the first and second chambers.

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.

The present invention relates to an intravenous infusion set providing delivery of intravenous fluid to patients. An intravenous infusion set (10) to administer continuous air free delivery of intravenous fluid to a patient, said intravenous infusion set (10) comprising: a drip chamber (12), a flexible infusion line (22) of sufficient length connecting a lower end (20) of the drip chamber (12) to a standard connector (24) at the patient end so that a needle or a catheter could be connected to the patient; a roller clamp (26) arranged between the drip chamber (12) and the standard connector (24) being movable along the length of the flexible infusion line (22), said drip chamber (12) provided with a spike (14) on the upper end (16) and a flow regulating and stopping member (18) at its lower end (20) configured to administer continuous air free delivery of intravenous fluid to patients.

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.
