US Patent 7798994 Needle shield to septum interconnect

The present invention is a catheter device. The catheter device will include a septum that is housed within a housing. The septum is designed such that it will seal the housing. The catheter device also includes a needle shield. The needle shield is configured to retain a needle if the needle is withdrawn from the housing. The catheter device is further configured such that the septum includes a receiving portion that is designed to engage a portion of the needle shield. However, if the needle is withdrawn from the housing, the needle shield will disengage from the septum so that the needle shield may be separated from the septum.
