AI Technical Summary

Technical Problem

Existing systems face challenges in connecting the newborn's circulatory system to an oxygenation device post-uterus separation, particularly in cannulating small blood vessels like arteries and veins within the umbilical cord, requiring precise manipulation and minimizing blood loss to prevent umbilical cord spasms and hypoxia.

Method used

A cannulation system with a cannula, needle, and dilator assembly that allows quick and safe cannulation of blood vessels, featuring a Y-connector, slit seal, and collet jaws for secure attachment, enabling one-handed operation and connection to an ECMO system.

Benefits of technology

Facilitates rapid and effective cannulation of blood vessels, reducing blood loss and umbilical cord spasms, thereby improving the success of the procedure and ensuring continuous oxygen supply to the newborn.

Abstract

To provide a cannula insertion system including a cannula system and a cannula insertion device.SOLUTION: A cannula system comprises: a cannula having a distal end portion and a proximal end portion on the side opposite to the distal end portion; a cannula lumen extending through the cannula between the distal end portion and the proximal end portion; and a slit seal disposed on the cannula and configured to receive a cannula insertion device. The cannula system is configured to be in fluid communication with a blood vessel and with an oxygenation device.SELECTED DRAWING: Figure 1
