Locking taper fluid connection interfaces
This document provides fluid handling components. For example, this document relates to taper interface connections such as, but not limited to, luer taper interface connections used to couple fluid handling components in a medical or laboratory setting. In some embodiments, the threaded connection on the male portion of the taper interface is comprised of one or two opposing tabs, rather than a 360° collar like conventional luer lock fittings. As such, the taper interface components provided herein are readily manufacturable with a lower cost than conventional fittings that have a collar. In some embodiments, the taper interface components provided herein are configured for coupling by way of a quick connection technique.
1. A taper interface connection system comprising:
a male component comprising:
a first tab with a first thread portion;
a second tab with a second thread portion, the second tab being disposed in relation to the first tab such that the second thread portion faces the first thread portion; and
a tapered male body having an axial male component lumen therethrough, the tapered male body disposed between the first tab and the second tab and spaced apart from the first tab and the second tab by equal distances; and
a female component that is releasably coupleable with the male component, the female component comprising a first external thread portion and a second external thread portion that is separate from the first external thread portion, wherein the first external thread portion and the second external thread portion are located on opposing outer portions of the female component and each individually mesh with either the first thread portion or the second thread portion when the male component and the female component are coupled, the female component defining a female component lumen and a tapered female space that tightly receives the tapered male body when the male component and the female component are coupled,
wherein the male component lumen and the female component lumen are in fluid communication and provide a substantially leak-proof connection when the male component and the female component are coupled.
2. The taper interface connection system of claim 1 , wherein the male component and the female component both comprise moldable materials.
3. The taper interface connection system of claim 1 , wherein the male component and the female component both comprise metals.
4. The taper interface connection system of claim 1 , wherein the tapered male body and the tapered female space are compliant with a recognized standard for luer fittings.
5. The taper interface connection system of claim 1 , wherein the tapered male body, the tapered female space, the first thread portion, the second thread portion, and the external thread are all compliant with a recognized standard for luer lock fittings.
6. The taper interface connection system of claim 1 , wherein the male component and the female component are coupleable by rotating the male component by about 90° in relation to the female component.
7. A mechanical clamping device comprising:
a clamp portion comprising:
at least two contact faces, a first of the contact faces configured to travel in response to an applied force, each contact face configured to contact a sample when loaded into the mechanical clamping device; and
a load element configured to cause the two contact faces to apply a clamping force to the sample when loaded into the mechanical clamping device; and
a male taper interface portion extending from the clamp portion and comprising:
a first tab with a first thread portion;
a second tab with a second thread portion, the second tab being disposed in relation to the first tab such that the second thread portion faces the first thread portion;
a tapered male body having an axial male component lumen therethrough, the tapered male body disposed between the first tab and the second tab and spaced apart from the first tab and the second tab by equal distances; and
a female component that is releasably coupleable with the tapered male body, the female component comprising a first external thread portion and a second external thread portion that is separate from the first external thread portion, wherein the first external thread portion the second external thread portion are located on opposing outer portions of the female component and each individually mesh with either the first thread portion or the second thread portion when the tapered male body and the female component are coupled.
