A fluid connection apparatus, in which a carrier body and washer configuration are overmolded together, is configured for use in a fluid transfer assembly. The carrier body may be generally U-shaped, having two substantially parallel portions connected by a bridging portion. Each substantially parallel portion of the fluid connection apparatus includes a washer configuration including one or more washers. The fluid connection apparatus may be used to connect a fluid line fitting to an apparatus intended to provide or receive fluid through the fluid line, using a connector having a fluid passage formed therein. The fluid line fitting is placed between the two substantially parallel portions, and a connector having a fluid passage formed therein is inserted through one side of the fluid connection apparatus, through the fluid line fitting, and through the other side of the fluid connection apparatus. The fluid connection apparatus may include stabilizing features, such as ribs in the bridging portion or enlarged radii, to protect against distortion and breakage.

An adapter for putting two incompatible medical systems in fluid communication with each other. The adapter may have a continuous outer diameter and may include two segments: a first segment composed of a rigid material and including a first portion and a second portion, the first portion having a continuous outer diameter and the second portion defining one or more flanges, the first segment defining a first passage therethrough; and a second segment composed of a flexible material and coupled to the first segment, including a first portion and a second portion. The first portion of the second segment may have an inner surface configured to surround the flanges of the second portion of the first segment, and the second portion of the second segment having a tapered inner surface, the second segment defining a second passage therethrough that is continuous with the first passage.

This disclosure relates to a hose connector formed at the end of a rigid pipe body used to connect the pipe body to a flexible polymeric hose. The hose connector includes a frustoconical front end extending outward from a tip to a radially enlarged first ring portion that terminates at a circumferential first step. A radially reduced second ring portion extends from the first step backwards at a constant diameter to a circumferential rear edge. A circumferential second step extends from the second ring portion rear edge backwards in a decreasing circumferential diameter to a mid-section of the pipe body. A flexible hose is adapted to be inserted by pressure over the pipe body at the tip end until it passes beyond the second step to at least the mid-section of the pipe body.

Vacuum adapter apparatus, systems, and related methods for use with inflatable structures having relief valves are disclosed. An example vacuum adapter for a relief valve of an inflatable structure includes a first end portion adapted to connect with the relief valve, a second end portion adapted to connect with a vacuum fluid line, an intermediate portion coupled between the first and second end portions, a vacuum chamber extending through the intermediate portion between the first and second end portions such that a fluid is conveyable through the vacuum chamber from the relief valve to the vacuum fluid line, and a fluid seal positioned on the first end portion. The fluid seal is configured to engage an outlet portion of the relief valve to maintain a negative gauge pressure in the vacuum chamber that causes the relief valve to open during a deflating process of the inflatable structure.

An improved quick connector with code verification is provided. The quick connector includes a connector body, a connector sleeve, and a sliding lock latch. The connector body includes a verification indicia on its outer surface, and the connector sleeve is movable over the connector body and includes an indicator window that aligns with the verification indicia. The sliding lock latch is moveable from an unlatched position to a latched position through transverse openings in the connector sleeve and the connector body. The sliding lock latch includes first and second wing elements to prevent clockwise and counter-clockwise rotation of the connector sleeve relative to the connector body. The sliding lock latch also includes a locking tab on its outer surface to prevent retraction of the connector sleeve from the connector body.

The invention relates to the production of profiled hose nipples. The invention was based on the object of providing a method and an apparatus which allow hose nipples of the type outlined in the introduction to be produced in a simple manner such that the formation of burrs is avoided and there is no reduction in diameter. This object is achieved in that during the forming of pipe portions (1) in the apparatus (2, 7, 9) according to the invention in the region of the subsequent ring-shaped webs (4) of the nipple profile (3), the material of the pipe portion (1), at its outwardly pointing end (4), does not come into contact with the tool in the region of the parting joints (6) of the apparatus (2, 7). This can be realized by additional cavities (14) in the tool (2, 7).

A swiveling hose coupler assembly for inhibiting hoses from becoming kinked includes a first male fitting that is insertable into a female end of a first hose. The first male fitting is hollow to pass a fluid from the first hose outwardly through the male fitting. A second male fitting is rotatably coupled to the first male fitting such that each of the first male fitting and the second male fitting extends along a common axis, and the second male fitting is rotatable about the common axis. The second male fitting is insertable into a female end of a second hose to inhibit the first hose and the second hose from becoming kinked. The second male fitting is hollow to pass the fluid from the first male fitting into the second hose.

A gas infuser includes a mixing chamber and a liquid injector. Gas is supplied into the mixing chamber and liquid flows through openings of the injector to mix with the gas in the mixing chamber and form a gas-infused liquid.
