Embodiment Construction

[0048] figure 1 is a front elevation view of the present invention, which provides a dental syringe system. Dental syringes are also known as quick-change syringes. Such syringe and needle systems have some applications in general medicine. The quick-change syringe system allows for easier, simpler and safer drug delivery if administered in a syringe rather than a vial or vial.

[0049] Existing technology requires users to:

[0050] The drug is drawn from vials and vials into a medical disposable (plastic) syringe, usually using a large bore needle (20 or 22 gauge); the drug is then injected into the body.

[0051] If the drug is placed in a cartridge, the present invention can be administered using a smaller bore injection needle.

[0052] Systems when assembled form components commonly designated as 3.

[0053] The syringe 5 includes a thumb ring 7 and a finger grip 8 on the syringe body 9 .

[0054] I will describe and claim the thumb ring 7 as the actuator ring 7 in...

Abstract

A cartridge syringe system includes a syringe (5). The syringe has a tip-ward direction and a ring-ward direction. The syringe (5) has a syringe body (9) and an actuator ring (7). A shaft (10) slidably mounts the actuator ring (7) to the syringe body (9), with a harpoon (11) at a tip-ward end of the shaft (10). The syringe body (9) has a spiral mount external to the syringe body (9) for removably mounting a sheath (20) to the syringe body (9), on a cooperating internal spiral sheath mount. The syringe body (9) and the sheath have similar openings. The sheath opening can be rotated to coincide with the syringe body opening, for inserting a needle assembly into the syringe body, or for removing the needle assembly. The sheath opening can be rotated to obstruct the syringe body opening, for retaining the needle assembly in the syringe body.

Description

[0001] This application is a PCT application with priority consideration to and benefit from all common subject matter of US Provisional Patent Application No. 62118310, filed February 19, 2015. technical field [0002] The present invention relates to a novel dental syringe system. Background technique [0003] In dental syringe technology, traditional syringes are adjusted so that the dentist retracts the syringe plunger after the initial penetration to make sure he is not touching a blood vessel, the dentist puts his thumb loop over the thumb of the syringe to make sure if the blood has Access to the syringe, pull back the plunger and observe the anesthesia vial. If the blood had already entered the syringe, it meant he had to find a new location for the injection point to avoid injecting the anesthetic through the blood vessel and into the bloodstream. This is done for two reasons: [0004] 1. Anesthetics usually contain epinephrine, which can adversely affect heart ra...
