Universal safety syringe

Universal safety syringe having a protective cap, a cylinder, a plunger and a cannula mounted on a cannula base, it being the case that the cannula base is designed such that it can be pushed firmly against a stop in the protective cap, that the protective cap, which can be pushed externally onto a cone, corresponding to a Luer cone, of the cylinder, is provided with a narrowed section, which is provided on the inside of the cap, in front of a recess designed for receiving the cannula base, and delimits the push on travel, that a recess which receives a cannula base is provided with an undercut which prevents the cannula base from being removed in the forward direction, and with an undercut of which the effect can be overcome by the cone being widened from the inside and which is provided for safeguarding the cannula stop from being pushed in unintentionally during insertion of the syringe, and it also being the case that the plunger is designed with a section which widens the cone cylindrically and with a mushroom-shaped plunger head, which comes into pulling contact with the needle stop. A preferred embodiment provides a safeguard against the plunger being unintentionally pushed in too early and too far.

Safety syringe with retractable standard needles

Safety syringe with retractable standard needle including a syringe barrel, a plunger and an injection needle. A commonly used standard medical injection needle can be firmly fitted with the needle holder in accordance with the requirement of a user. The inner wall of the internal chamber at the open end of the syringe barrel is formed with an entrance recess extending along the axis of the internal chamber. The operating end of the plunger is formed with a radially outward projecting stopper section for preventing the needle pulling mechanism of the plunger from being accidentally latched with the needle pulling mechanism of the syringe barrel.

Safety needle cannula module that is activated by a safety syringe and plunger module

A safety needle cannula module in interchangeable combination with a safety syringe and plunger module, wherein the safety needle cannula module is formed with one of a variety of needle cannula sizes and wherein said safety syringe may be one of a variety of syringe sizes. The safety needle cannula module with needle cannula of desired size is attached to a safety syringe module wherein said safety syringe is a desired size. After medication is injected into a body with the safety needle cannula and the safety syringe, the safety syringe module reacts with the safety needle cannula module and further causes said safety needle cannula to be automatically retracted and disposed within the hollow plunger said safety syringe module.

Automatic safety syringe construction

A safety syringe construction (10) including a conventional syringe member (20) equipped with a fixed tubular male sleeve member (20) and spring biased moveable tubular female sleeve member (30) which is slidable relative to the tubular male sleeve member (30). The male (30) and female (40) sleeve members are provided with a locking unit (15) for releasably engaging the female sleeve member (40) relative to the male sleeve member (30).
