Abstract: Apparatus selectively attachable to the outer case of a cellular telephone or other similarly sized portable device. The apparatus desirably includes a housing containing an elastomeric band that is principally disposed inside the housing when the apparatus is not in use. The apparatus may include a kickstand and a cardholder. The elastomeric band can be used as a selectively retractable carrying strap when the cell phone or other similar device is not in use. Alternatively, the flexible continuous loop can be used, for example, to support the cell phone around a user's neck for hands-free use when the user is engaged in other activities.

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: An isokinetic control module and method for incorporation on both new and existing exercise equipment. The control module replaces standard friction and hydraulic resistance components offering constant speed of the moveable elements of the machine rather than a selected resistance or weight. The constant user-generated resistance prevents injury and enhances strength training of the targeted muscle groups by maintaining constant strain on those muscles throughout the exercise. This method and device incorporates both a PCFC valve and a check valve device, removing all resistance the moment the user stops applying force to the machine. This enhances safety and facilitates the rapid return of the lifting element to its home position between repetitions. An optional graphical display is also disclosed.

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 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 personal proximity alert device and associated behavior modification system configured to monitor and/or detect a hand of a user or another person or object penetrating a personal protection zone around the facial area of the user and to alert users to such detected risks and/or to the presence of others approaching within a predetermined minimum socially safe distance to reduce the likelihood of accidentally transmitting viruses or other pathogens.

Abstract: A safety syringe for medical use having an injection molded plastic body with a tubular barrel, a transverse finger flange surrounding the barrel and two upwardly projecting wings with substantially flat, outwardly facing surfaces disposed forwardly of the finger flange, a plunger assembly slidably engaging an inside wall of the barrel, a needle with a tip projecting forwardly from the barrel, and a needle safety shield slidably engaging the body between the wings, wherein the transverse finger flange has a window that allows core pin insertion through the window during injection molding of the body, the plunger assembly has a proximal end cap that is integral with the plunger handle and abuts a rearwardly facing surface of the transverse finger flange, and the needle safety shield has a distal end with a cylindrical needle guard that is forwardly movable following use of the syringe to guard the needle tip.

Abstract: A dental safety syringe comprising selectively attachable barrel and plunger assemblies, the barrel assembly desirably further comprising a needle cartridge containing a needle holder and spring, and having a distal end from which a needle can be made to project forwardly while administering a medication and then subsequently withdrawn into the needle cartridge to avoid contamination following or between injections. The needle cartridge also comprises a proximal end having a recess into which an ampule containing medication can be inserted prior to connecting the plunger assembly to the barrel assembly so that a rubber dam in the distal end of the ampule is pierced by the proximal end of the needle whenever the syringe is fully assembled.

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 medical device configured as a blood collection tube holder, the device having a body with two spaced-apart, oppositely facing, coaxially aligned needles including a forwardly facing venipuncture needle and a rearwardly facing fluid discharge needle, the two needles being held by first and second needle holders separated by a compressible fluid seal defining part of a fluid path between the two needles and the two needle holders. The body also includes a discharge needle displacement member that is manually repositioned following removal of the last blood tube holder so that the discharge needle displacement member contacts the second needle holder and displaces the second needle holder and the fluid discharge needle laterally inside the body to initiate retraction of the venipuncture needle into a rearwardly projecting needle retraction chamber.

Abstract: An endless loop rope climbing machine that maintains a constant rope speed through a hydraulic resistance mechanism. This method and device uses a climbing rope threaded about a tapered friction sheave connected to a hydraulic pump via a shaft. The user selects a desired fluid flow rate corresponding to a preferred rope climbing speed using a flow adjustment mechanism. Force exerted on the rope by the climber initiates the flow of fluid through the hydraulic system. Fluid is propelled through the system to a pressure compensated flow control (PCFC) valve in fluid communication with the hydraulic pump. A pressure compensating spool within this PCFC valve shifts in position to regulate fluid flow, returning a constant velocity of fluid to the hydraulic pump. The shaft connected to the hydraulic pump rotates at a consistent speed regardless of the force applied by the climber, thereby maintaining the steady rope climbing speed selected by the user.
