The conical frustum tip advantageously facilitates aspirating a medicant, using a common Luer needle for filling and also prevents the possible unintentional retraction of the needle assembly due to hydraulic pressures encountered when drawing the medicant from a vial and during the handling of the syringe. Moreover, the conical frustum tip advantageously allows the syringe to be conveniently prefilled with a medicant at a pharmacy and capped, then transported to a patient with or without needle assembly as desired. This design is a significant advantage for many healthcare workers involved in the processing and handling of syringes until ultimate delivery of the medicant to a patient. | 09-13-2012 |
20120232481 | Retractable Syringe Needle Assembly - A retractable needle syringe, including a needle stem and breakable ring having a plurality of fingers and grooves. These fingers and grooves are configured to mate with a plurality of ribs and grooves in a syringe barrel distal end to provide anti-rotation of the needle stem with respect to a syringe barrel.

20120259280 | Splatter Prevention Mechanism for a Syringe - A syringe including a barrel and a plunger slidably disposed within the barrel is disclosed. A distal end of the barrel defines a roof, and an elongate tip, in fluid communication with the barrel, extends from the roof. A protrusion forming a ridge may be disposed on one of the roof of the barrel and the plunger head. When the plunger head contacts the roof, the protrusion forms a channel between the plunger head and the roof. The channel isolates fluid within the channel from the elongate tip, which in turn reduces the spray of fluid through the distal end of the syringe. In another embodiment to reduce the spray of fluid through the distal end of the syringe, an impulse reduction system may be used to reduce or prevent the proximal portion from applying a distally directed impulse to the distal portion after the breakable connection is broken. | 10-11-2012 |

20120310160 | SAFETY CARPULE SYSTEM WITH INTEGRAL RETRACTABLE NEEDLE - A safety carpule system with integral retractable needle includes a piston element disposed between a needle hub assembly and a plunger element, each being axially slideable within a cylindrical housing. A medication-filled fluid chamber is defined between the plunger element and the piston element. The piston element is forced to into a fluid release position by way of an increase in fluid pressure within the fluid chamber, which in turn is caused by actuation of the plunger element toward the needle hub assembly by way of a syringe plunger rod. When the piston element is in fluid release position, the medication is able to flow from the fluid chamber through the needle as the syringe plunger rod is further compressed. Once the carpule system is spent, the piston element is latchably engaged by both the needle hub assembly and the plunger element, thus allowing the needle to be fully retracted into the housing upon return of the syringe plunger rod to its extended position. The spent carpule system with retracted needle is then conveniently removable from the syringe barrel for safe handling and disposal. | 12-06-2012 |

The tip retaining sleeve surrounds tip retaining arms of the plunger tip allowing the tip retaining arms to grasp the plunger arm. After the plunger arm is pulled backwards, sleeve ribs prevent the tip retaining sleeve from moving in a forward direction. As the plunger arm is pushed forward, the tip retaining arms are no longer surrounded by the tip retaining sleeve and the tip retaining arms move outwards and release the plunger tip. After the plunger tip has been released from the plunger arm, the plunger tip and the plunger arm cannot be reconnected and the single use syringe cannot be reused. The plunger arm is removed from the syringe body and locked onto a guide lock and covers the needle tip. | 01-31-2013 |
20130053773 | Retractable Syringe with a Cutting Crown - A retractable syringe comprises a cutting head mounted on a plunger of the syringe. When the plunger is advanced to expel fluid from the syringe, the cutting crown cuts a retention mechanism which holds a needle unit of the syringe, allowing a drive mechanism to drive the needle unit into the syringe.
