Patent number: 8029279Abstract: An improved safety hypodermic syringe for dental applications which further includes first finger grip, preferably a thumb ring, on the end of the plunger, forward finger holders and a lock mechanism, which includes extending fingers for grasping the top of the reciprocal sliding sheath. The syringe assembly also includes a reciprocal tubular needle sheath disposed on the exterior of the syringe body and a latch mechanism engaging the syringe body and the sheath to latch the sheath in a needle-covering position after delivering contents from the syringe body. The fingers, preferably biased by a living hinge hold back the locking ring while the dentist administers anesthesia through the syringe. An internal spring, which engages the syringe body and the sheath, expands to move the sheath to cover the needle point. The spring is a non-uniform helical spring having multiple 360° turns with each turn uniformly spaced from adjacent turns.Type: GrantFiled: September 17, 2010Date of Patent: October 4, 2011Assignee: Protectus Medical Devices, Inc.Inventor: John A.

Patent number: 8016796Abstract: The present invention safety device is a one-piece needle assembly that has a base and a housing pivotally connected to the base. The base has a distal portion to which a needle is fitted. At the base there is formed longitudinally along its distal portion a catch mechanism that may be in the form of an anchor projection. At the back wall of the housing there is extended another catch mechanism that may be configured in the form of two clasping fingers. Also providing in the housing is an integral hook. As the housing and the base are pivoted relative to each other, and as the needle makes contact with the hook, the respective catch mechanisms at the base and the housing also make contact with each other, resulting in the coupling of the catch mechanisms and the coupling of the needle to the hook. As a result, the catch mechanisms are interlocked and the needle is fixedly retained by the hook within the housing.Type: GrantFiled: May 27, 2005Date of Patent: September 13, 2011Assignee: Smiths Medical ASD, Inc.Inventors: Robert Simas, Jr., David MacLean

Patent number: RE43141Abstract: A medical device is provided for collecting fluid samples from a patient, such as blood samples. The device includes a needle having a forward sharpened tip that is retracted into the housing of the device after use to prevent exposure to the contaminated needle. The rearward end of the housing is open, forming a socket for receiving a fluid container, such as a vacuum tube, that will receive the fluid sample. A needle retainer releasably retains the needle in the extended position against the rearward bias of a biasing element. After use, the medical professional retracts the needle by pressing an actuation button, allowing the biasing element to displace the needle rearwardly. A guide track guides the needle during retraction, tilting the needle off-axis.Type: GrantFiled: April 13, 2007Date of Patent: January 24, 2012Assignee: MDC Investment Holdings, Inc.Inventors: Thor R.
