Abstract: Improvements in a safety hypodermic needle and a method of making the same are disclosed. The improvements relate to a commercial embodiment of a patented safety needle and comprise a tubular member extruded from a flexible elastomeric or rubber-like polymeric material. The tubular member is extruded with two ribs extending from the outer wall of the tubular member and spaced apart 90° circumferentially. The wall of the tubular member is provided with through cuts to form a cutout on one wall portion and an elongated lever on the opposite wall portion in the 90° space between the ribs. The cuts separate the wall of the tubular member into two outwardly flexible arms, each having a single rib thereon adjacent an edge of the arm. One end of the tubular member is stretched over the needle hub of a hypodermic needle and the other end is stretched over a needle cup which houses the sharp needle point. The needle cup is provided with a needle opening through which the needle extends during use. After use the flexible arms automatically return the needle cup into a protective position housing the needle point. Latching mechanisms are provided on the hub and lever for releasably holding the arms in a “cocked” position or for permanently holding the arms in a disabled or “safe” condition to prevent inadvertent needle sticks.

Abstract: A safety hypodermic needle and a method of using the same are disclosed. The safety needle comprises a hypodermic needle and a protective sheath molded of an flexible polymeric material. The protective sheath comprises a needle cup which encloses the sharp needle point and is supported on a plurality of outwardly flexed ribs. The needle cup has a needle opening which is misaligned with the needle axis in the at rest or unflexed condition of the protective sheath. Application of transverse and axial forces to the needle cup aligns the needle with the opening and cause the ribs to bow outwardly so that the needle passes through the opening and into the patient's body.

Abstract: A safety hypodermic needle and a method of using the same are disclosed. The safety needle comprises a hypodermic needle and a protective sheath molded of a flexible polymeric material. The protective sheath comprises a needle sleeve with an open central passage which houses the sharp needle point. The needle sleeve is supported on a plurality of inwardly bowed ribs in an unflexed “at rest” condition in which the needle point is retained inside the needle sleeve to prevent inadvertent needle sticks. Levers attached to the ribs are used to move the ribs from their inwardly bowed unflexed “at rest” condition to an outwardly bowed flexed condition to permit the needle to pass through the open central passage of the needle sleeve and into a patient's body. After the needle is removed from the patient's body, the ribs automatically return to the unflexed “at rest” condition without the assistance of any additional biasing or restoring means.

Abstract: In a system and method for peripheral impedance plethysmography, an electrode for application to the patient's limb includes two outer current electrodes and two inner voltage electrodes. A distance between the two inner electrodes is automatically input into an analyzing device, either as a pre-stored value or as determined automatically from the electrode. Peripheral blood flow is calculated in accordance with that distance.

Abstract: An adjustable and disposable blood pressure cuff comprises a bladder provided with adhesive layers on both sides thereof which are covered by peelable strips. According to the method of using the cuff, selected strips or portions thereof on one side of the cuff are peeled away and removed. The cuff is then folded and adhesively secured to itself at the optimum width for the circumference of the limb of the patient. Selected strips or portions thereof on the other side of the cuff are peeled away and removed so that the cuff may be adhesively secured about the limb of a patient. In a second embodiment, a hook-and-loop fastener piece replaces the adhesive layer on the other side of the cuff for securing the cuff about the limb of a patient.

Abstract: The present invention is a multi-function fluid communication control system for effecting selective automated control to provide selected fluid communication between fluid reservoirs, instruments, and various pressure conditions which can be used in, for example, a catheterization procedure. The system includes multi-port fluid communication valves, such as three-port stopcocks which are connected as required by fluid conduits such as tubes. Each of the valves, in turn, are connected to a control mechanism such as stepper motors to provide the necessary fluid communication paths in response to the user's requirements. User requirements can be translated into the required valve movements through command signals operated by, for example, an appropriately programmed computer or microprocessor.
