Embodiment Construction

[0116] In general, safety syringes, methods of using safety syringes and safety syringe devices in which a sheath moves under force applied by a user into a position to at least partially cover a needle of the syringe are disclosed herein. In an exemplary safety syringe, the sheath is connected to the plunger, and a force is applied to the sheath by the user, thereby moving the plunger and sheath together. At a point along the inward travel of the plunger, the sheath separates from the plunger and continued application of force by the user moves the sheath to a position at least partially covering the needle. The safety syringe device surrounds a device that is configured to fit to a syringe such that the syringe is a safety syringe. That is, the exemplary safety syringe device can be the same as the safety syringe described herein and shown in the figures, with the barrel, needle, and / or syringe plunger removed.

Abstract

A safety syringe (100; 700; 1200) comprising: a tube (104; 704; 1204) having an opening at its end; a syringe plunger (108; 708; 1208) configured to adapted to move within the tube such that inward stroke of the syringe plunger causes the contents of the tube to expel from the opening; and a sheath (112; 712; 1212) configured for at least partially disabling the syringe after use Covering the opening of the tube with the sheath attached to the syringe plunger and configured for detachment from the syringe plunger at a point of inward stroke such that the sheath is able to move independently of the syringe plunger and the sheath after detachment A further movement at least partially covers the opening of the tube.

Description

technical field [0001] The present invention relates to a safety syringe and a device for fitting to a syringe to convert the syringe into a safety syringe. In particular embodiments, the invention relates to, but is not limited to, passive safety syringes and associated devices. Background technique [0002] In general, a syringe includes a plunger and a tube having a hypodermic needle at one end, the plunger being configured for movement within the tube such that inward stroke of the plunger causes a substance contained in the tube to be expelled from the needle . [0003] Safety syringes typically include some form of safety mechanism to protect healthcare personnel from hypodermic needle injuries after the hypodermic needle has been injected into a patient. Exemplary safety syringes may include a sheath to cover the needle, or may cause the needle to retract within the barrel of the syringe. [0004] Safety syringes can be broadly divided into "active" and "passive". ...
