MEDICAL FOUR-WAY STOPCOCKS WITH LOW RESIDUAL SIDE PORT VOLUME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050731 titled 'MEDICAL FOUR-WAY STOPCOCKS WITH LOW RESIDUAL SIDE PORT VOLUME

Simplified Explanation

The abstract describes a medical device that includes a four-way medical stopcock and a needleless valve. The stopcock has a body with a cock barrel and three stems, each having a port. The device also includes a rotatable cock placed within the cock barrel. The cock can position the ports in fluid communication in different combinations. The needleless valve has a valve stem that is disposed within the side stem of the stopcock, creating an internal volume. The volume is approximately 0.09 ml when the cock is in a specific position.

  • The medical device consists of a four-way stopcock and a needleless valve.
  • The stopcock has a body with three stems and ports.
  • The cock within the stopcock can rotate to connect the ports in different combinations.
  • The needleless valve has a valve stem that fits within the side stem of the stopcock.
  • The internal volume created by the valve stem, side stem, and cock is approximately 0.09 ml.

Potential applications of this technology:

  • Medical procedures requiring multiple fluid connections.
  • Intravenous therapy and drug administration.
  • Blood transfusions and blood sampling.
  • Dialysis and other medical treatments involving fluid management.

Problems solved by this technology:

  • Simplifies the process of connecting and disconnecting multiple fluid lines.
  • Reduces the risk of contamination and infection by eliminating the need for needles.
  • Provides a compact and efficient solution for fluid management in medical devices.

Benefits of this technology:

  • Improved patient safety by minimizing the risk of needlestick injuries and infections.
  • Enhanced convenience and ease of use for healthcare professionals.
  • Efficient fluid management with the ability to control and adjust fluid flow.
  • Compact design allows for space-saving and portability in medical devices.


Original Abstract Submitted

in general, one aspect disclosed features a medical device, comprising: a four-way medical stopcock, comprising: a body defining a cock barrel and comprising: a first stem having a first port, a second stem having a second port, and a side stem having a side port; and a rotatable cock disposed within the cock barrel, wherein: the cock places the first port and second port in fluid communication when the cock is in a first position, and the cock places the first port, second port, and side port in fluid communication when the cock is in a second position; and a needleless valve having a valve stem, wherein the valve stem is disposed within the side stem such that an internal volume defined by the side stem, the valve stem, and the cock when the cock is in the third position, is approximately 0.09 ml.
