Disclosed herein are embodiments of a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway, a male coupler having a second passageway, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system. Further disclosed herein are embodiments of a connector system for releasably connecting together tubes, whereby the connector system includes at least one valve biased by a valve-biasing member disposed external to or outside of the fluid flow path.

Needleless connectors are described. An example needleless connector includes a housing and a compressible valve. The housing may define an internal cavity and may include a body section having a first port and one or more internal contact tabs and a base section having a valve mount and a second port. The compressible valve may be disposed within at least a portion of the internal cavity and be movably retained within the housing. The compressible valve may include a flange portion for securing the compressible valve within the housing. A central longitudinal axis of the housing may be defined by a coaxial arrangement of the first and second port. The one or more internal contact tabs may be arranged to contact an outer side surface of the flange portion such that a radial force substantially orthogonal to the central longitudinal axis is provided for securement.

Described is a priming device to prime a gas from a fluid delivery system by receiving the gas and a fluid used to push the gas into a chamber, the priming device including a housing having a chamber, an inlet port, and an opening to release gas received into the chamber. The device further includes a valve extending from the inlet port toward the chamber and a cover body comprising one or more flexible protrusions extending axially inward from an inner surface of the cover body. The cover body has an open first end, an open second end, and an axis between the first end and the second end, the first end configured to couple with a male luer connector, the second end configured to couple with the inlet port of the housing, wherein the cover body is moveable relative to the housing.

A flushing apparatus according to embodiments of the present disclosure includes: a main body configured to connect a connection pipe for guiding a hazardous medicinal liquid harmful to a human body when exposed to an ambient air and a patient connection module for injecting the hazardous medicinal liquid into a patient, the main body configured to form a first flow path for guiding the hazardous medicinal liquid from the connection pipe to the patient connection module, the main body including a flushing portion forming a second flow path connected to a predetermined connection point located between both ends of the first flow path; and a flow rate reduction part disposed at upstream side of the connection point in the first flow path and configured to reduce a flow rate of the hazardous medicinal liquid flowing through the first flow path. The present disclosure shows various embodiments of the flushing apparatus.

This disclosure provides a perfusion device, an anesthetic vaporizer, and an anesthetic machine. The anesthetic vaporizer includes a vaporizer body and the perfusion device. A feed port and a tank are provided in the vaporizer body. The perfusion device includes a mounting assembly, an ejector rod assembly, and a valve core assembly that is provided with a liquid inlet channel. The mounting assembly includes a mounting seat that is mounted on the feed port and provided with a hollow structure having an opening at both ends. The valve core assembly is movably mounted on one opening of the hollow structure, and the ejector rod assembly is movably mounted on the other opening of the hollow structure and forms a sealed structure with the mounting assembly. The ejector rod assembly may drive the valve core assembly to move toward the tank, and the liquid inlet channel communicates with the hollow structure.

A one-piece medical connector has a unitary body. The unitary body includes a rigid portion that forms a housing. The unitary body also includes a resilient portion located at least partially within the housing. At least a movable portion of the resilient portion is configured to move relative to the rigid portion. Movement of the resilient portion selectively permits fluid flow through the connector. The rigid portion and the resilient portion form a one-piece unitary connector.

A device to couple a vascular access device to a medical device may include a body, a spring, and a housing. The body may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The proximal end of the body may include a connector. The housing may be coupled to a proximal end of the spring and may enclose the connector. A distal end of the spring may be coupled to the body. The housing may include a flap, which may include an antimicrobial compound. When the housing is disposed in a proximal position, the flap may cover the connector, the antimicrobial compound may contact the connector, and the spring may be uncompressed. In response to movement of the housing from the proximal position to a distal position, the spring may be compressed and the flap may open.
