Abstract: A syringe includes a barrel having a proximal end, a distal end having a distal tip defining a channel, and a sidewall extending between the proximal end and the distal end. The syringe also includes a tip cap removably connected to the distal tip of the barrel restricting fluid flow from the channel. The tip cap includes a connector configured to receive the distal tip of the barrel forming a friction engagement with the distal tip, a cap shield connected to and extending about the connector, and a release tab extending proximally from the cap shield that secures the tip cap to the barrel. A prefilled flushing syringe including a predetermined volume of a fluid disposed within the barred of the syringe, as well as methods for expulsion of fluid from the syringe and of assembling the syringe and tip cap are also disclosed herein.

Abstract: A syringe with an integrated vein finder is disclosed, which illuminates a potential venipuncture site of a patient and identifies a vein that is suitable for venipuncture with the syringe, for blood collection or intravenous drug administration. The syringe portion of the system includes a syringe barrel and a pointed-tip needle projecting from the distal end of the barrel for venipuncture. An illumination module is coupled to the syringe barrel; it has an illumination source that projects an electromagnetic beam into an illumination zone distal the syringe's pointed tip, for illuminating and identifying a subcutaneous vein. The integrated vein finder and syringe system is operable by a sole clinician, such as a phlebotomist, who can easily manipulate the syringe and illuminate the venipuncture site with one hand, without assistance of another clinician.

Abstract: Methods and server systems for computing fraud risk scores for various merchants associated with an acquirer described herein. The method performed by a server system includes accessing merchant-related transaction data including merchant-related transaction indicators associated with a merchant from a transaction database. Method includes generating a merchant-related transaction features based on the merchant-related indicators. Method includes generating via risk prediction models, for a payment transaction with the merchant, merchant health and compliance risk scores, merchant terminal risk scores, merchant chargeback risk scores, and merchant activity risk scores based on the merchant-related transaction features. Method includes facilitating transmission of a notification message to an acquirer server associated with the merchant.

Abstract: Systems and methods for shadow testing are provided. A new service may be brought online that corresponds to an existing service. The new service may be designated for shadow testing. A call may be received for the existing service from a calling device. The received call may be provided to the existing service, while an asynchronous call corresponding to the received call may be provided to the new service. A result may be received from the existing service in response to the provided call, and a result may be received from the new service in response to the asynchronous call. The result received from the existing service may be used in responding to the received call. Data regarding the result received from the new service may be logged, but the result received from the new service may be excluded from use in responding to the received call. One or more metrics evaluating performance by the new service may be generated.
