An organism paracentesis device comprises a first tube member and a second tube member. The first tube member comprises an injection tube filled with a medicament, a piston and a first syringe needle. The second tube member comprises a sampling tube and a second syringe needle. Both ends of the second syringe needle are in the form of syringe needle. Using one end of the second syringe needle to penetrate a cover of the sampling tube which is vacuumed, such that the second syringe needle's the other end which is penetrating into an organism will extract a sample from the organism because of the vacuumed sampling tube. The medicament filled in the injection tube is ejected both when the first and second syringe needles are penetrating into and pulled out of the organism, so as to avoid the cells of sampled organism being spread to other places.

There is provided herein a system, device and methods for performing minimally invasive spider vein treatments. In some embodiments an apparatus for eliminating spider veins comprises a dual syringe mechanism that includes a pusher for pushing sclerosant materials into a target vein, and an extractor for extracting debris from a target vein; a needle for application into a target vein; and a Y-connector connecting each exit of the dual syringe mechanism to the needle. In some implementations the apparatus's dual syringe mechanism includes a locking mechanism to enable controlled advancing of the syringe pusher.

The invention relates to a system for injecting a fluid through or into the human skin, optionally by needle-free injection or by injection with a needle, with (i) an injection device (110) which includes an ampoule (112) with an ampoule body (114) forming a chamber for receiving the fluid to be injected; an ampoule piston (118) which is axially movable and sealingly guided in the chamber; an outlet (124) disposed at the distant end of the ampoule (112) for the fluid to be injected, wherein the ampoule (112) is rounded in the region of the outlet (124) and the rounded region forms a skin contact surface (126) for the needle-less injection through or into the human skin; and at least one first coupling element (128) of a coupling device which is arranged at the distal end of the ampoule (112) on the ampoule body (114) and configured for sealingly and reversibly attaching a needle attachment (150), and (ii) a needle attachment (150) with a cannula part (152) comprising a needle (156); and an adapter part (154) proximally connected to the cannula part, wherein the adapter part (154) has at least one second coupling element (162) of the coupling device, the coupling device configured for sealing and reversible attachment on the ampoule (112) of the injection device (110), characterized in that the needle attachment (150) is constructed in two parts, wherein the needle attachment (150) can be reversibly disassembled into the cannula part (152) and the adapter part (154).
摘要:
A device is provided to protect the hypodermic needlepoint of a syringe from being dulled as it penetrates through the stopple of a fluid vial for the purpose of filling the syringe with fluid from the vial. Specifically, the device includes a blunt needle that covers the hypodermic needle and that interacts with the syringe to establish relative friction forces between them. Importantly, this friction force is less than the friction force subsequently established between the dull needle and the stopple. Thus, after the hypodermic syringe has been filled, and is withdrawn from the fluid vial, the stronger friction force between the stopple and the dull needle causes the dull needle to remain with the stopple as the hypodermic syringe is removed from the fluid vial.
摘要:
A cartridge for a medication dispensing device which includes multiple septums. The cartridge includes a body and an axially shiftable piston in fluid-tight engagement with an interior surface of the body. The first septum covers a dispensing port that opens to an interior hollow of the body at a proximal location. The second septum covers a filling port that opens to the interior hollow. The first septum is arranged to be engaged by a dispensing conduit moving generally perpendicular to the axial direction for fluidly communicating with the interior hollow during a dispensing operation of the device. The second septum is arranged to be engaged by a filling conduit for fluidly communicating with the interior hollow during filling of the cartridge.

In general, the invention features needles, with or without lumens, that contain a barrel being transparent or translucent or having a transparent or translucent portion. Needles of the invention may further include a lumen, the interior of which is visualizable through the transparent or translucent portion. A needle may also include a portion to which a suture is capable of being attached.
摘要:
A syringe assembly including an adapter, a sheath and filling spike for connecting to said adapter and an intravenous connector for intravenously administering medicine to a patient. The barrel may be connected to the adapter and the filling spike for filling the barrel with medicine. The medicine can then be injected into a patient through either the needleless intravenous injection system or through a retractable needle assembly.
