Since the Needlestick Safety and Prevention Act endorsed in 2000, healthcare industry has been looking for easy-to-use, functional reliable safety syringes at affordable cost. This demand has however not been satisfactory met yet despite variety safety syringe designs have been proposed, prototyped or commercialized. The major obstacle of adopting state-of-the-art safety syringes is its high cost and the concern of functional reliability. Besides the factors such as syringe integrity, functional reliability, designing a safety syringe shall take user’s preferences into consideration. We are of the opinion that a good safety syringe shall at least meet following criteria:

• One-hand operable throughout whole administration process;
• The sharp needle is retracted and contained automatically;
• User has the control over the activation of needle retraction;
• Ensure no premature activation of safety mechanism;
• The syringe is disabled to prevent from reusing it;
• Minimum change on the established administration protocol;
• Last but not least, able to mass production at reasonable cost.

Question remain is how to best balance among aforementioned criteria? We, MedicalChain International Corp., have an answer. syringes are developed based on a patented technological platform that offering following advantages:

• A retractable needle hub to enable needle being locked inside the barrel after usage, thus safeguard user from needlestick injuries;
• A dual function collapsible plunger rod act as trigger of the retraction mechanism, and disable the syringe to prevent reuse of it;
• A user activated safety system to ensure no premature needle retraction before medication is completed;
• Engineered safety ensures all safety features are fully integrated to ensure its functionality, easy-to-use and convenient disposal;
• Existing administration protocol can be employed, just pushing on the plunger rod to activate the safety mechanism after the needle is removed from the patient body.

The integration of one handed, user-activated automatic needle retraction and containment inside the barrel, with simultaneous plunger rod disabled differentiate syringes from other safety syringes.

All of syringes are manufactured by automated assembly systems to deliver consistent quality and safeguard functional reliability. MCI has developed, in collaboration with our partners, high-throughput automated assembly systems for the mass production of safety syringes. Key technological features includes:

• MCI's automated assembly workstations incorporate various robots to achieve high throughput, repeatability, quality control and lower production cost. Each workstation is equipped with touch panel controller to perform special tasks, such as quality inspection, force sensing, malfunction alarm, etc.
• The on-line quality monitoring systems enables instant automatic inspection, components or work-in-process that fail to meet specified quality criteria are rejected automatically.
• MCI’s automated assembly line is a modular design that not only able to accommodate space constraints, but also make rapid and cost-effective capacity boost feasible.

• User Activated Needle Retraction (No Premature Retraction)
  The built-in retraction mechanism can be activated by the user only after the medication has been fully completed, an audible “click” sound signals the retraction mechanism is triggered off. No premature retraction of needle would occur before complete dosage is delivered.
• Collapsible Plunger Rod (Syringe Auto-Disabled)
  While the retraction mechanism is activated, the plunger rod breaks up into two pieces. This auto-disabled feature can prevent the device from re-use or needle re-exposure.
• Self Containment of Needle (Sharp Safety and Easy Disposal)
  While the plunger rod is collapsed, the needle set will be retracted into and contained inside the syringe barrel immediately. It requires no additional action to render the device sharp safe, thus protect people from the risk of needle stick injuries.
• Share Existing Administration Protocol (User-Friendly)
  The usage of syringes are almost identical to standard disposable syringes except user to activate the retraction mechanism after the needle is removed from patient’s body, this feature can minimize need of training and incorrect use.

• Substantially Reduce Injection-derived Infection Risk
  User-activated automatic needle retraction and containment requires no additional action to render the device sharp safe, thus eliminate the exposure to the contaminated needle.
• One-hand Operable
  The safety mechanism of syringes is fully integrated and allowing user activate it using one single hand as mandated by German TRBA 250, thus render healthcare worker’s another hand free to do other necessary work.
• Ensure Complete Medication
  The safety mechanism of syringe can only be activated after complete dosage is delivered, risk of wrong dosage due to premature retraction of needle is eliminated.
• Protect User and Others
  Permanent containment of the needle within the barrel, together with the disabled plunger rod, protect people from the risk of needle re-exposure and device re-using.
• Convenient Disposal
  The safety mechanism of syringe render the device sharp safe, thus facilitate easy handling and convenient disposal of used syringe, existing institutional disposal policy can be applied.

Unlike other patented auto-retractable safety syringes, proprietary safety mechanism of syringes does not need engagement of the plunger rod with the needle holder to render the needle retractable, or the requirement of any measurement to break up the spring retainer and release the spring accordingly.

All of syringes are protected by a strong global deployed IP portfolio.
