Description

Protective sleeve for preventing finger from being pricked during extraction of atraumatic needle

Technical Field

The utility model relates to the field of medical appliances, in particular to a protective sleeve for preventing fingers from being stabbed when an atraumatic needle is pulled out.

Background

In clinical practice, more and more cancer patients choose infusion port placement due to the need for long-term chemotherapy or long-term intravenous therapy. In order to prevent the port from being blocked during the infusion port placement, the non-invasive needle needs to be penetrated periodically for maintenance, when the maintenance is finished and the non-invasive needle is pulled out, a three-finger fixed port body is needed, the other hand uses wrist force to pinch the edges of the two sides of the non-invasive needle by the thumb and the index finger, and the non-invasive needle is pulled out of the port body upwards, at the moment, the hand pulling the needle can be downward due to inertia action at the moment of pulling the needle because the supporting point is on the wrist, and the hand of the fixed port body is extremely easy to be pricked, so that needle pricking is generated.
