摘要： A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

摘要： A syringe for medical use, the syringe having a selectively retractable needle and a multifunctional needle holder and retainer ring assembly including a needle holder with a head section having an inwardly tapering frustoconical section of the fluid pathway and a rearwardly facing annular surface surrounding the rear opening, and an elastomeric retainer ring with a substantially unexpanded collar extending rearwardly beyond the rearwardly facing annular surface to increase needle pushout force, reduce activation force and improve fluid flow through the syringe. Annular projections inside the retainer ring and on the outer surface of the head section of the needle holder are also disclosed.

摘要： An intravenous catheter introducer for medical use having a body, a frontal attachment that is disposed in transverse sliding engagement with a front part of the body, a hub tube assembly that is releasably supported by the frontal attachment, and a retractable catheter insertion needle and needle holder that are biased rearwardly by a spring offset laterally from the needle axis, whereby lateral repositioning of the body relative to the frontal attachment following vascular insertion moves a needle retraction cavity disposed inside the body into substantial coaxial alignment and causes the needle holder to be retracted into the needle retraction cavity.

摘要： Systems and methods of a dosage verification system are disclosed that can be used by a healthcare worker or an individual self-administering an injection to create a digital record verifying the dosage of a medicinal fluid drawn into a syringe prior to an injection. The dosage verification system includes a medical syringe and an imaging device configured to view and selectively capture, process, store, and transmit a digital image of the syringe from which the volumetric dose of medicinal fluid drawn into the fluid chamber of the barrel can be determined and/or verified prior to an injection.

摘要： A blood collection device for medical use having a body with longitudinal flow channel and a needle retraction chamber, a slide assembly slidably engaging the body in a plane transverse to the flow channel through the body, a forwardly projecting nose, a device stabilization member with flexible wings projecting oppositely from a cylindrical hub attached to the nose, a rearwardly biased venipuncture needle projecting forwardly from the nose, and a tubular needle cap having proximal and distal ends, wherein the proximal end of the tubular needle cap is insertable between and is releasably held by the nose and the cylindrical hub. Cooperatively configured sets of ramps and stop surfaces limit lateral sliding movement of the body relative to the slide assembly.

摘要： A blood collection tube holder having a retractable single needle and a body comprising substantially parallel and laterally spaced apart barrel and needle retraction cavities separated by a partial wall that facilitates lateral movement of the single needle from the barrel cavity into alignment with the needle retraction cavity to initiate needle retraction. The barrel and a frontal attachment to the barrel are cooperatively configured to facilitate relative sliding movement between in a direction that is transverse to the longitudinal axis through the retractable single needle to initiate needle retraction.

摘要： A device having a housing; a cannula projecting forwardly from the housing; a connector useful for attaching the device to a fluid source or receptacle; a fluid flow path establishing fluid communication between the cannula and the connector; a retraction mechanism biasing the cannula away from its projecting position; and an actuator supported by the housing and configured to modify the fluid flow path so as to terminate fluid flow through the device, seal off the fluid flow path, and release the retraction mechanism to retract the cannula into the housing. The subject device is particularly preferred for use in the medical field, for example, as part of an infusion set or as a collection device for blood, or other fluids or flowable matter.
