摘要： A disposable safety needle assembly and safety enclosure for internally shielding a used or contaminated needle includes a needle assembly having a needle cannula slidably disposed within a safety enclosure. An angular orientation to the needle within the enclosure maintains an insertion angle allowing the safety enclosure to remain substantially flush with a dermal surface during and while the needle is inserted. The safety enclosure also includes an internally disposed flexible safety member. The flexible safety member has face portion transversely situated and having a safety feature disposed to the needle and that slides thereon. Retracting the needle within the safety enclosure to a point wherein the sharp tip of the needle is beyond the needle protection section of the flexible member causes the protection section to travel transversely to the direction of motion of the needle. As a result, the safety feature receives the sharp tip of the needle.

摘要： An intradermal mini-needle interface has a penetration limiter providing a skin contact edge and a hollow hypodermic needle having a beveled penetrating portion protruding forward beyond the skin contact edge by no more than 3 mm. At least one skin contact surface defines a skin contact plane parallel to, or at a shallow angle to, the needle axis. The skin contact plane intersects the skin contact edge substantially at a base of the penetrating portion. Preferably, the penetration limiter is asymmetric under rotation about the needle axis.

摘要： A safety syringe cylinder has a structure for attaching a syringe needle precisely. The syringe needle can be retracted into the syringe cylinder for bending. A hook seat is formed at a lower end of the needle. An annular hook groove is formed at a top end of the push rod cap. The hook seat is engaged with the annular hook groove so as to control the displacement and bending process of the syringe needle. Thereby, the processing of undesired syringe needle is safe, reliable and convenient.

摘要： A safety vein syringe with retractable special needle, including a syringe barrel, a plunger, an injection needle and a guiding mechanism formed between the needle holder and the plunger. By means of the guiding mechanism, the plunger can be only axially moved within the barrel without rotation and two needle pulling members can be easily aligned with each other and latched together. The first needle pulling member is formed on the needle holder or the plunger, having at least one rotatable click. The second needle pulling member is formed on the plunger or the needle holder, having a detent. When the piston of the plunger is pushed to the bottom, the detent is easily and firmly engaged and hooked with the click. Thereafter, the injection needle and the needle holder can be together pulled into the barrel with the tip of the injection needle positioned under the shoulder section of the barrel. Then the plunger is further pushed to press the tip against the shoulder section and bend the tip so as to destroy the injection needle.

摘要： A retractable safety syringe has a hub at the end of its plunger which engages a needle carrier when the plunger is depressed so that the needle carrier can be withdrawn into the syringe along with the needle. To facilitate breaking off the plunger shaft, thereby trapping the spent needle within the syringe, there is a conically shaped flangible section between the plunger and the shaft which defines a sharp notch allowing the shaft to be broken off at any angle.

摘要： A syringe (2), of the type having a barrel (4) with a plunger (6) disposed within the bore of the barrel, includes two needle assemblies (22) housed within needle assembly guides (14) positioned along the exterior (16) of the syringe barrel. Each needle assembly guide provides a path along which the needle assembly moves, between an extended position, with the needle exposed, and a retracted position, with the needle encompassed by the needle guide. A flow path (36, 44) exists between the interior (46) of the syringe barrel and each needle assembly when each needle assembly is in the extended position. The use of two needles allows one needle to be used to aspirate the liquid pharmaceutical into the syringe and the other, unused needle to be used to give the injection. Each needle assembly is irreversibly locked (54, 60) when moved into the retracted position to prevent syringe reuse.
