    Abstract: Gravitational flow systems and equipment sets for the sequential administration of medical liquids wherein a primary source (11) can be administered at a flow rate independent of the flow rate of a secondary source (13) and including a barrier (47) substantially impervious to air to prevent the inadvertent administration of air when the secondary source (13) is depleted. The air barrier may consist of either a hydrophilic membrane (45) or mechanical float valve (65) or a diaphragm operated barrier member (241).

    Abstract: Gravitational flow system and equipment sets for the sequential administration of medical liquids wherein a primary liquid from a first source (11) can be administered at a flow rate independent of the flow rate of secondary liquid in a second source (13). A combined air barrier and liquid sequencing valve chamber (32) controls the sequencing of the various flows and prevents inadvertent administration of air when the second source is depleted by means of a hydrophilic barrier (45). The valve chamber (32) is divided into two separate flow chambers (34, 41) which are in liquid communication with the respective sources (11, 13) and in air communication therebetween by means of hydrophobic membrane (53).

    Abstract: An improved venipuncture device comprises a catheter having a catheter hub at one end, with a needle having a needle hub at one end and a sharpened tip at the second end extending through the catheter and catheter hub. A resilient reseal is mounted in the catheter hub for sealing the catheter upon removal of the needle. The improvement comprises a wing hub having an axial bore adapted for telescopic reception and attachment to the catheter portion. A pair of oppositely extending flexible wings are integrally formed and extend from the wing hub. An area of reduced thickness on each of the flexible wings along a portion of the width of the wings adjacent to the wing hub allows the wings to be easily folded upward. As a result, the wings may be pinched together between the thumb and index finger, thus, making it easier to insert the needle into the vein of the patient.

    Abstract: An improved venipuncture device comprises a catheter having a catheter hub at one end, with a needle having a needle hub at one end and a sharpened tip at the second end extending through the catheter and catheter hub. The needle is adapted for insertion and removal from the catheter. A fin extends substantially vertically from the needle hub and is constructed and arranged for gripping the device in a manner which facilitates venipuncture.

    Abstract: An improved flow control device for regulating the flow of fluid through flexible tubing wherein the flow control device utilizes a rotatable member with trunnions positioned to be captively guided and rotated along guide surfaces. The rotatable member is easily inserted into the clamp body yet once it is placed therein it is difficult to remove without excessive force. The clamp body affords a rigid structure with the opposing walls being fixed at their ends yet are flexible enough to afford entry of the rotatable member into the clamp body for placement of the trunnions in the guide surfaces. In one embodiment, a ramp means is provided through an infeed section wherein the ridge portions forming the ramp merge with the guide surfaces so that when the trunnions of the roller move up the ramp and onto the guide surfaces, an outward flexing of the clamp wall is effected with a retention of the trunnions on the guide surfaces. In another embodiment, the walls defining an open slot at the top of the clamp body are weakened such as by beveling so as to permit the trunnions of the roller to enter into the clamp cavity and be retained on the guide means.
