Abstract: 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.

Abstract: 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.

Abstract: A device configured to receive and safely store a plurality of used needle-containing medical apparatus such as syringes, IV catheter introducers, bodily fluid collection devices and blood collection tube holders and to dispense a sterile medical apparatus having the same or a similar shape, size and configuration as that deposited into the device.

Abstract: 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.

Abstract: 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.

Abstract: A blood collection tube holder embodying two coaxially alignable needles, the first needle being a forwardly facing venipuncture needle and the second needle being a rearwardly facing fluid discharge needle. The first and second needles are satisfactorily supported by a frontal attachment and body, respectively, that are disposed in relative sliding engagement along an interface that is transverse to the first and second needle and that extends at least from the second needle to an opening into a needle retraction chamber that projects rearwardly from the body. The subject device is configured to receive and support a conventional blood collection tube of the type used to collect blood samples.

Abstract: A medical syringe having a barrel with a substantially cylindrical, longitudinally extending fluid chamber, a needle retraction cavity substantially coextensive in length with the fluid chamber and disposed adjacent and parallel to the fluid chamber, and at least one substantially flat, outwardly facing display area configured to receive and display an array of volumetric measuring indicia in alignment with and proximal to the fluid chamber.

Abstract: 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.

Abstract: A medical device having a forwardly-projecting needle and a selectively-movable needle cap that can be variously positioned to cover all or a portion of the needle, depending upon whether the device is, for example, being transported, aspirated or used to inject a therapeutic fluid. The device can optionally be configured to enable retraction of the needle into the body for safe disposal following use.

Abstract: A medical device attachable to the front of a conventional syringe and having a hub assembly selectively attachable to the syringe, a nose projecting forwardly from the hub assembly, a rearwardly biased needle retraction mechanism seated inside the nose, a retractable needle projecting forwardly of the nose, and a fluid flow path from the fluid chamber through the hub assembly, nose, needle retraction assembly and needle, wherein the needle is retracted into the nose and a retraction tube external to the syringe by rotating the syringe relative to the nose.

Abstract: A medical device having a frontal attachment and a connector housing having at least a body part of an associated medical apparatus, the frontal attachment slidably engaging the connector housing and having a forwardly projecting, rearwardly biased needle and a needle retraction assembly, and the connector housing having a needle retraction cavity laterally offset from the needle in a first position, the needle retraction cavity being selectively movable relative to the frontal attachment following use to reposition the needle retraction cavity into alignment with the needle to permit retraction.
