Abstract: A splint includes a pair of hingedly-mounted frame sections for receiving the two limbs of the patient. Each frame section includes two frame members secured together to occupy a common plane, and an intermediate member pivotally mounted to the first frame member from an inoperative position in the common plane between the frame members, either to a first operative position on one side of the common plane or to a second operative position on the other side of the common plane. A flexible strip is joined between the second frame member and the intermediate member, and is of a width larger than the spacing between the frame members so as to form a curved bed for supporting the right limb of the patient when the intermediate member is in its first operative position, or the left limb of the patient when the intermediate member is in its second operative position.

Abstract: Liquid infusion apparatus comprises a drip chamber in which an outlet tube projecting into the chamber is enclosed by a cap including a side wall enclosing the upper portion of the outlet tube. The cap side wall has an inner diameter which is substantially largre than the outer diameter of the outlet tube, to thereby define a large passageway at the entrance of the outlet tube. This passageway substantially reduces the flow velocity of the liquid at its interface with the air in the drip chamber, and thereby substantially eliminates the possibility of air bubbles being trapped within the liquid fed through the outlet tube under high rates of liquid flow and under exceptionally rough handling conditions, such as when the transfusion is being administered while the patient is in a helicopter or in a land vehicle.

Abstract: A traction splint particularly useful for supporting a fractured leg in traction includes a rigid frame having a pair of longitudinally-extending frame members attachable at the inner end to the fractured leg and connected together at their opposite ends to receive the outer end of the leg. The outer end of the frame includes a pair of attachment jaws formed with a concave configuration for receiving the lower ends of the tibia and fibula and for limiting against the internal and external malleolus; the attachment jaws being carried by the supporting member extending transversely across, and slidable longitudinally of, the pair of frame members at the outer end of the frame.

Abstract: A fluid control device for a liquid transfusion line comprises an inlet connector and an outlet connector, and a flexible conduit defining two, three or more passageways extending in parallel between them to provide a plurality of parallel paths for the flow of the fluid. The device further includes a restrictor in one or more but of the passageways restricting the flow according to a fixed predetermined rate lower than that of unrestricted passageway, and a manual control member for selectively closing the passageways to produce a flow of the fluid from the inlet connector to the outlet connector according to a preselected fixed rate.

Abstract: A device for dispensing a liquid from a collapsible container comprises a pair of elastic plates hingedly mounted to each other along one edge permitting them to be pivoted to an open position or to a closed position, and a sleeve of flexible material secured to the pair of elastic plates along their hinged edges for receiving a liquid-filled collapsible container. Each of the elastic plates is pre-formed with a curve which is convex from the side facing the flexible sleeve. The arrangement is such that when the liquid-filled collapsible container is received within the flexible sleeve and the two curved elastic plates are pivoted to their closed positions, they apply, due to their elasticity, a continuous force to the collapsible container for dispensing the liquid therefrom. The device further includes retainer devices for releasably retaining the elastic plates in their closed position.

Abstract: Apparatus for the induced infusion of a liquid from a flexible liquid bag comprises a pumping bulb, elastic inflatable means coupled to the bulb for inflation thereby, and a flexible sleeve for retaining the liquid bag firmly against a first portion of the inflatable means for applying the pressure thereof to the bag to induce infusion of the liquid therefrom. The elastic inflatable means includes a second portion which serves as an accumulator for accumulating pressurized fluid pumped by the bulb and comprises an outer non-elastic sheath for limiting the accumulation of the pressurized fluid therein. In one described embodiment, the two mentioned portions of the elastic inflatable means are constituted of separate units, one being a bag-presser including an inflatable bladder against which the liquid bag is pressed by the flexible sleeve, and the other being a separate accumulator including an inflatable tube enclosed by the non-elastic sheath.

Abstract: Liquid flow control devices are described particularly useful for attachment to an infusion administration set including an infusion liquid container connected by a line to an infusion needle, comprising: a conical socket member at one end of the device for connecting same to the infusion container side of the line; a conical pin member at the opposite end of the device for connecting same to the infusion needle side of the line; and fixed-rate liquid metering components including a stem formed with a metering groove and an overlying sleeve, the metering components being located between and communicating with the socket and pin members for metering the liquid flow therebetween according to a preselected fixed rate. The overlying sleeve is resilient and includes a pair of spaced apart protuberances which provide a finger gripping portion and enable the resilient sleeve to be deformed for providing an enlarged flushing passageway for the liquid.

Abstract: A device for application to a syringe, or other finger-pressure actuated article, includes a member to be received on the pressure-applying element of the article so as to be engaged by the user's finger when actuating the article, the finger-engaging member being effective to soften the pressure transmitted from the user's finger and to provide an indication to the user when a predetermined pressure has been applied. A number of embodiments are described wherein the indication of the predetermined pressure is produced by the yielding of the finger-engaging member at a greatly increased rate when the predetermined pressure is reached. Other described embodiments include a rigid element having a pointed tip engaged by the user's finger when the predetermined pressure is reached; and a still further embodiment is described wherein the indication of the predetermined pressure is provided by graduation markings.

Abstract: A microbe barrier device particularly useful for draining body liquids while avoiding retrograde infection is described, comprising a housing including an inlet connectable to a liquid line and an outlet through which the liquid from the line is drained, a one-way valve within the housing between its inlet and outlet and permitting the one-way flow of the liquid only from the inlet to the outlet, and a barrier within the housing between its inlet and the one-way valve and including an antiseptic substance in contact with all surfaces of the inlet side of the valve through which the liquid flows.

Abstract: A pressure-indicating syringe comprises a barrel, a plunger assembly movable therein and having an outer shaft and an inner piston, finger-engaging elements on the barrel and on the plunger shaft for moving the piston to inject fluid through an apertured end wall of the barrel, and an elastic connection between the finger-engaging elements of the plunger shaft and the piston enabling the piston to be displaced relative to the shaft an amount corresponding to the pressure on the piston during the injection of the fluid, thereby providing an indication of the injection pressure.According to a further feature, the barrel includes a retaining member engagable with the plunger shaft for retaining the latter in an intermediate position with respect to the barrel, thereby enabling the device also to indicate a change in pressure in the injection compartment, and also to be used for applying a slow continuous injection.
