Problems solved by technology

For example, conventional thermoplastics are limited by a maximum autoclave temperature of 132°C and an exposure time of only 10 minutes
Additionally, conventional designs should not be held in place by clamps or under load during sterilization to avoid permanent deformation

Embodiment Construction

[0015] exist Figure 1 to Figure 9 Embodiments of a pipe joint system, method, and apparatus for creating compression between a pipe and a joint are disclosed. For example, some implementations (see for example Figure 1 to Figure 3 ) consist of disposable plastic clamps that grip and seal pipe connections with barbed fittings to form assemblies or piping systems.

[0016] These embodiments may include a pipe 21 having an axial end 23 ( image 3 ). Connector 25 (as Figure 6 The barb fitting shown in ) is inserted into the end 23 of the pipe 21 . A clip 31 ( figure 2 and 3 ) at around connector 25 ( Figure 6 ) near the end 23 of the pipe 21 to form a substantial compression seal and connection therebetween.

[0017] In the illustrated embodiment, the clamp 31 may further include a body having first and second portions 33, 35 connected by one or more hinges 37 and unlockable from an open position ( figure 1 ) to a latched closed position ( figure 2 and 3 ). The l...

Abstract

A retainer clenches on tubing to secure a fitting and form a compression seal and connection therebetween. The retainer has first and second portions joined by a hinge and is movable from an open position to a closed position. The closed position defines an aperture in which the tubing and fitting are clenched. The retainer has a small aspect ratio with respect to the diameter and axial width of the retainer. A rib circumscribes and extends radially into the aperture to place a pre-load on the tubing to intensify a compression force of the retainer.

Description

technical field [0001] The present invention relates generally to clamps, and more particularly to improved systems, methods and apparatus for tubing connectors that create compression between tubing and hose barb fittings. Background technique [0002] Thermoplastic elastomer (TPE) or silicone tubing is joined by fittings that are inserted into the tubing and secured by external plastic clamps or clamps. These fittings typically include barb connectors, while these clamps include cable ties, turbo clamps, Kwik Clamps TM , Connectors and similar items. Cable ties are inexpensive but form an unreliable seal for some applications, while other types of connectors are more expensive. [0003] In pharmaceutical and medical applications, such tubing connectors are often subjected to autoclave environments at high temperatures and pressures. Autoclaving can significantly alter the properties of the materials used to form the tubing, connectors, and clamps, thereby reducing the...
