Abstract: A variable flow rate controller is provided herein. The controller may have a linearly traversable switch such that the controller is primed to flush air bubbles out of the fluid system of the controller prior to administering fluidic medication to a patient. Moreover, the controller may have a plurality of valves which may be independently opened and closed by a caming surface. To close the valve, a first seal may be disposed between offset inlet and outlet to prevent fluid from flowing from the inlet to the outlet. To open the valve, the first seal is disposed on one side of both of the inlet and outlet. Fluid if permitted to flow from the inlet to the outlet.

Abstract: A gravity fed infant feeding device is disclosed. The gravity feeding device may have a cover with a through hole that allows liquid nutrients within the infant feeding device to be fed to an infant by way of gravity. If the infant feeding device clogs up, then either an integrated pump or a separate pump may be applied to the infant feeding device to increase pressure and push out the clog from the system. the through hole may be covered with a hydrophobic filter to allow air to pass there through and allow the feeding of the infant by way of gravity yet liquid nutrients within the infant feeding device cannot escape or be contaminated during use.

Abstract: A safety needle device is provided for protecting a user against needle-stick injuries. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A biasing member is engaged to the sheath assembly and is configured to apply a force thereupon towards the distal housing opening. The biasing member defines a centerline which is parallel to the needle's distal needle portion. An indexer is engaged to the biasing member and is operative to increase or decrease a spring force of the biasing member by rotating the indexer. A trigger member is engaged to the biasing member for retaining the sheath assembly within the needle housing against the force urging the sheath assembly towards the distal housing opening.

Abstract: A safety needle device for protecting a user against a needle-stick injury. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A trigger member retains the sheath assembly within the needle housing against a force urging the sheath assembly towards the distal housing opening. The trigger member is sized and configured to release the sheath assembly from retention to allow the sheath assembly to transition towards and out of the distal housing opening via the force. This causes the sheath assembly to enclose the distal needle portion and protect the user against the needle stick injury.

Abstract: A safety needle device for protecting a user against inadvertent needle-stick injury. This needle device includes a needle housing having a distal housing opening. An arcuate groove extends within the needle housing terminating adjacent the distal housing opening. A needle is disposed within the arcuate groove having a distal needle portion extending away from the needle housing through the distal housing opening. An elongate sheath assembly surrounds the needle within the groove. A biasing member is disposed within the needle housing and is configured to move the sheath assembly throughout the length of the arcuate groove and through the distal housing opening. The sheath assembly then completely enclose the distal needle portion.

Abstract: A blood drawing system including a closeable first conduit through which drawn blood can flow; a first pressurizeable collection vessel for receiving blood therein; a hollow-shaft member; a second conduit leading from the first conduit to the first collection vessel; and a third conduit leading from the first conduit to the hollow shaft member connectable to a negative-pressure second collection vessel. Closing the first conduit allows blood transfer from the first vessel into the second vessel without exposure to or inclusion of any external devices to accomplish such transfer. Also included is an intravenous system with a conduit through which medicament liquid can be delivered and from which medicament liquid-free blood can be withdrawn. A first pressurizeable vessel first removes and conserves for reintroduction residual medicament liquid from the conduit, while thereafter a second negative-pressure vessel draws subsequent medicament liquid-free blood from the conduit.

Abstract: A safety needle assembly comprising a needle with a distal needle end having a sleeve member which has a distal sleeve end forming an aperture. The sleeve member is mounted to the needle by accommodating the same through its sleeve end's aperture. The sleeve member is axially movable toward the distal needle end until the needle becomes displaced from the aperture and the distal needle end is contained within the distal sleeve end.

Abstract: A liquid medicament dispenser for controlled infusion delivery of liquid medication to a patient. The dispenser includes an elastomeric bladder for housing the liquid medication, an inlet in communication with the bladder for receiving the liquid medication into the bladder, and an outlet in communication with the bladder for discharging the liquid medication into an infusion tube for delivering the liquid medication to the patient. A flow regulator for controlling flow rate of the liquid medication through the infusion tube includes a flow rate adjuster with a manually operable adjuster knob for setting flow rate and an encasement housing releasably securable about the adjuster knob for impeding access to the adjuster once the proper rate has been set.
