Multi-Lumen Axial Cryogenic Connector

摘要

An embodiment of the invention is a cryo-connector, a connector that allows for the delivery and return of a cryogen in an axial configuration. In one embodiment, the connector is a tri-axial configuration allowing for the delivery and return of pressurized cryogen as well as the application of an independent vacuum in the third lumen. Various configurations, however, may accommodate any number of luminary spaces such that cryogen (or other fluids) and/or vacuum spaces may be created in a fashion complementary to the components that the connector will affix to and interconnect with. The connectors can be utilized with any low temperature, cryogenic device and at varying pressures.

主权项

1. A connector for integrating an instrument with a cryoengine, the connector compatible with cryogenic temperatures and pressures, including pressures which exceed the critical point of a cryogen while providing a leak-proof seal, the connector comprising:
a first portion having a body and a collar, wherein the body comprises an external surface having one or more connectivity features embedded thereon and an internal configuration having a first channel and a second channel which pass through the body; and a second portion having a mating feature to interconnect with the first portion, the second portion further comprising:
a first sleeve including an outer wall with a first passageway formed therein;a second sleeve having a second passageway and a cavity formed therein to receive at least a portion of the first sleeve, the first passageway extending through the second passageway;a third sleeve having a third passageway and a cavity formed therein to receive at least a portion of the second sleeve, the second passageway extending through the third passageway; andwherein a secondary channel is formed between the second sleeve and the third sleeve, and the secondary channel is connected to the second passageway through at least one through-hole passageway;wherein the first passageway, second passageway, third passageway, through-hole passageway and secondary channel are configured to (1) allow a supply of cryogen to flow through the first passageway, second passageway and third passageway and (ii) allow return cryogen to flow through the third passageway, second passageway and through-hole passageway into the secondary channel between the second sleeve and third sleeve.
