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.

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.

The invention provides a multi-channel automatic infusion pump, comprising: a pump body; a pump door; an infusion switching mechanism, an exhaust device and a bubble detection device arranged on the pump body; wherein the infusion switching mechanism includes a multi-channel liquid-stopping clamp, a liquid-stopping clamp fixing base and a driving structure; the multi-channel liquid-stopping clamp includes a body and N channels formed on the body, each channel includes a liquid-passing section and a liquid-stopping section, the liquid-passing section and the liquid-stopping section on each channel are arranged in a manner that any one of a plurality of upper branch tubes is located on the liquid-passing section of the corresponding channel while other upper branch tubes are located on the liquid-stopping section of the corresponding channel. The invention can access at least two bags of liquid medicine at one time, and has the advantages of simple operation, time and labor saving.

A priming system including a resilient chamber having flexible walls and a first check valve in a first fluid pathway between the resilient chamber and a fluid reservoir such that a fluid flows through the first check valve only in a direction from the fluid reservoir toward the resilient chamber and the fluid returns to the fluid reservoir through a second fluid pathway between the resilient chamber and the fluid reservoir upon compression of the walls of the resilient chamber.

The invention provides a multi-channel automatic infusion control device, comprising: a pump body; a pump door; an infusion switching mechanism, an exhaust device and a bubble detection device; wherein the infusion switching mechanism includes a multi-channel liquid-stopping clamp, a liquid-stopping clamp fixing base and a driving structure; the multi-channel liquid-stopping clamp includes a body and N channels formed on the body, each channel includes a liquid-passing section and a liquid-stopping section, the liquid-passing section and the liquid-stopping section on each channel are arranged in a manner that any one of a plurality of upper branch tubes is located on the liquid-passing section of the corresponding channel while other upper branch tubes are located on the liquid-stopping section of the corresponding channel. The invention can access at least two bags of liquid medicine at one time, and has the advantages of simple operation, time and labor saving.

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 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 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.
