Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Surgical Instrumentation

Background:

  • Traditional fluid swivels often have limitations in the number of channels.
  • Previous triple-channel fluid swivels required further development for enhanced versatility.

Purpose of the Study:

  • To construct a functional quadruple fluid swivel with improved performance characteristics.
  • To enhance the versatility of fluid swivels for complex neuroscience experiments.

Main Methods:

  • Modification of a triple-channel fluid swivel by adding a fourth channel.
  • Alteration of the Touhey-Borst adapter and development of a new fixation method for rotary tubes using nuts and screws.

Main Results:

  • The modified swivel demonstrated low propensity to leaking and low resistance to rotation.
