Abstract: A disposable syringe comprises an arm, a plunger for receiving a fluid cartridge and including a surface projection, a needle assembly secured to a forward nose of the plunger, and a syringe barrel including a lengthwise slot on its surface with the projection disposed therein, a locking trough proximate a curved rear end of the slot, and a flexible latch provided between the rear end of the slot and the locking trough. After dispensing anesthetic, pulling the plunger rearward will retract the needle assembly into the syringe barrel until the projection moves from a forward end of the slot to the locking trough by passing the latch for locking the projection in the locking trough.

Abstract: A safety syringe for dispensing anesthetic is provided. After a dispensing operation pulling a plunger rearward will retract a needle assembly into a syringe barrel until a projection on a surface of the plunger moves from a forward end of an L-shaped slot to a rear square opening by passing under a stop for locking the projection in the square opening. The syringe is thus disposable and thereby prevents the used syringe from being used again by sterilizing the syringe.

Abstract: A circuit board structure and a method for fabricating the same are proposed. A plurality of conductive bumps and a first solder mask are formed on a carrier board, and the first solder mask is filled in the gaps between the conductive bumps and the conductive bumps are exposed. A first circuit layer and a first heat sink are formed on the first solder mask and the conductive bumps. A second heat sink is formed on the first heat sink, and a dielectric layer is formed on the first circuit layer and the first solder mask except the first and second heat sinks. A second circuit layer is formed on the dielectric layer and is electrically conductive to the first circuit layer. A third heat sink is formed on the second heat sink and a heat sink used for a chip mounting thereon is embedded in the dielectric layer. Therefore, the dimension of the circuit board is reduced and it is conformed to the dimension minimization progress of electronic devices.

Abstract: The present invention relates to a tabletop wind chime which comprises a base, a trunk, and attached sound-making devices that impact with one another to produce a pleasant sound when it is struck, shaken or blown. Branching rod-like features are attached to the trunk and sound-making devices may be attached to the branching rod-like features. The branching rod-like features have different angular shapes to provide more opportunities for a plurality of sound-making devices to collide to achieve a chiming effect with different tones. Furthermore, decorative light emitting devices may be added to increase the beauty of the invention. According to this invention, a wide variety of shapes, colors, themes, and sounds are made possible while it may be unavailable to traditional wind chimes. For example, a desktop wind chime resembling a tree is possible by designing the trunk and rod-like features like a tree with the sound-making devices like leaves or butterflies.

Abstract: Provided is a non-coring needle for venous access implantatable port comprising a puncturing assembly comprising two wings having a central sleeve, an L-shaped needle coupled to the sleeve, the needle including an annular groove on its horizontal portion, and a plastic tubing coupled to the sleeve; and a syringe barrel comprising an internal chamber having a forward opening, and an elongate slot formed on the syringe barrel and being in communication with the chamber. The groove is located at a first dent of the slot when the needle is concealed in the chamber in a non-use position, the groove is located at a forward second dent of the slot when the needle is fully extended from the opening for use, and the groove is permanently locked at a rear triangular recess of the slot when the needle is fully retracted into the chamber respectively.

Abstract: A safety syringe comprises a barrel having an aperture in a nose, a hollow plunger in the nose, the plunger having a hole, a sealing ring, a rear inverted conic detent, and a hypodermic needle, a fastener inserted through the aperture in the hole for fastening the barrel and the plunger together, and a sliding handle having a breakable neck, an internal clip-like latch having a central groove, and a plug fastened around the latch, the plug having a front tunnel. Whereby piercing the tapered end of the detent through the tunnel into the groove for fastening the plunger and the handle together at the end of fluid dispensing, removing the fastener from the aperture and the hole for disengaging the barrel from the plunger, and retracting the handle into the barrel will allow the neck to be broken or the needle to be bent prior to bending the neck.

Abstract: A safety syringe comprises a sleeve; a hollow barrel including a front nose; a needle; and a plunger snugly fitted within and slide through the barrel. After use, pull the plunger to cause the barrel to slide rearward until the needle is received in the sleeve again, thereby preventing a medical worker from being contaminated by microorganisms or blood on needle by accidentally pricking.
