Patent number: 8603040Abstract: An injection device is provided. The device includes a housing having a first end defining a first opening. A plunger is received within the first opening of the housing to move between first and second positions. A cartridge is disposed in the housing and has an interior serving as a reservoir for a drug. A delivery needle is disposed within the housing and is in fluid communication with the reservoir via an interruptible fluid channel. A locking mechanism is disposed in the housing. In the first position of the plunger the delivery needle is enclosed by the plunger and in the second position of the plunger the delivery needle is placed in an injection position and the plunger activates the locking mechanism whereby when the plunger returns to the first position the locking mechanism prevents the needle from being placed in the injection position.Type: GrantFiled: March 26, 2012Date of Patent: December 10, 2013Assignee: Becton, Dickinson and CompanyInventors: M.

Patent number: 5215528Abstract: An assembly for introducing a catheter into a blood vessel is provided. The assembly includes a needle hub having a needle secured thereto. The needle includes an elongate shaft having a bevelled tip. A portion of the needle shaft adjacent to the tip has a relatively large outside diameter. The shaft diameter of this portion exceeds the diameter, of the shaft portion adjoining the tip and the diameter of the shaft portion extending between the enlarged shaft portion and the needle hub. A catheter is mounted over the shaft of the needle, and includes an inner surface which bears against the enlarged shaft portion. A substantially leak-proof seal is thereby provided between the catheter and the needle shaft. A needle tip cover is slidably mounted to the needle shaft and is engageable with the enlarged portion of the shaft to prevent its removal therefrom. The catheter is releasably mounted to the needle tip cover.Type: GrantFiled: February 7, 1992Date of Patent: June 1, 1993Assignee: Becton, Dickinson and CompanyInventors: E.
