Problems solved by technology

[0005] However, a problem associated with UCB is that its collection appears to be a one-time possibility and the amount of blood that can be collected using current blood collection techniques is limited

Embodiment Construction

[0022] figure 1 An embodiment is shown in which the cannula itself is a length of flexible plastic tubing 4 made of a composition suitable for safe transport and storage of blood. The distal or tube insertion end is the bulbous tip 5, while the proximal end 6 is connected to the tube set; blood collection in utero is provided to a removable blood bag 7, which is thereafter redirected via a second removable blood bag 8 And collected outside the uterus. The cannula slides through the inner diameter of the stainless steel surgical needle 9 or trocar with a push or pull force having transition fit characteristics. The needle has a distal tapered point or needle insertion end 10 ( Figure 4 and Figure 5 ) and the proximal end 11, the proximal end 11 is square and perpendicular to and coupled to the carrier tube 13. The length of the needle is sufficient to allow sufficient extension 12 from the cannula housing to penetrate the umbilical vein. The proximal end of the needle is...

Abstract

A cannulation assembly comprising: a housing; a needle selectively extendable from a proximal end of said housing; a tube arranged to pass through the housing and through a bore of said needle such that an insertion end of said tube is arranged to selectively project from an insertion end of said needle; a slide mounted to the needle in sliding engagement with the housing and arranged to move the needle from a retracted position to an insertion position such that the needle projects from said housing; wherein said slide is further arranged to move the needle from the insertion position to a locked position such that the needle is fully retracted.

Description

technical field [0001] The present invention relates to the extraction of umbilical cord blood, in particular, to a device and method for realizing the extraction of umbilical cord blood. Background technique [0002] It is well known that umbilical cord blood (UCB) is of increasing importance and is a rich source of stem cells. Stem cells are known to divide to produce new red blood cells that carry oxygen to the brain, new white blood cells that are used in the body's immune system, and new platelets that help blood clot. It is currently estimated that stem cells can be used to treat more than 45 malignant and benign diseases. These diseases can include certain cancers such as leukemias, immune disorders, and genetic diseases. [0003] In many cases where bone marrow is currently used, UCB also provides a readily available source of stem cells for transplantation. Therefore, there are many advantages to using UCB instead of other sources of stem cells such as bone marro...
