ABSTRACT:
A sterility guard for piercing devices, connectors and needles such as are used in the medical and surgical fields, which gives positive indication if the same has been removed from the piercing device or other connector and subsequently replaced, thereby compromising the sterility of the device.
In one form a tubular guard closed at one end is adapted to be applied over a blood spike, for instance, and a projecting portion at the open end of the guard is provided with an integral extension which is engageable in an opening in a portion of the blood spike or a connector of another kind. This extension has a weakened or attenuated portion which is broken when the guard is removed to give a positive indication that the guard may have been removed even though it is later replaced.
In another form the guard is used to protect the sterility of the otherwise exposed ends of a pair of connectors or the like. In this form the guard itself may comprise a tubular member open at both ends and an extension such as referred to in the preceding paragraph will be provided at each end of the tubular guard, one of the extension being connected with each of the connector portions which is being protected by the guard.
