Abstract: A cap or closure for a pharmaceutical vial includes a fill hole to permit filling of the vial with the cap in place. In one form the vial and cap assembly comprises an open-top vial covered by a cap having a depending peripheral skirt. The inner surface of the cap skirt and the outer surface of the vial are provided with complementary mating interlock elements that preclude manual removal of the cap. The cap includes an integral tear member, defined by one or more weakened, partially circumferential weakened junction lines, such that pulling away the tear member along the junction line allows both manual removal of the cap and ready visual confirmation that vial integrity has been breached. The cap includes a fill hole permitting the filling of the vial with the cap in place. The fill hole is closed, after filling, by a resilient stopper having a configuration effectively precluding its manual removal, so that post-filling tampering and contamination are precluded.

Abstract: An operating table with a table top comprising a head section, a back section, a kidney elevator section, a seat section and a leg section, mounted on a base for being raised and lowered relative to the base, slid endwise relative to the base for X-Ray or C-arm examination of a patient on the table, and tilted endwise and laterally relative to the base, the table having controls at its head end, the back section being adjustable to act either as a back or leg support and the leg section being adjustable to act either as a leg or back support for placing a patient in a sitting position with the patient's head either at the head end or foot end of the table.

Abstract: Method of forming a rubber latex glove having a textured interior surface and a textured exterior surface, one of the textured surfaces being transfer textured and the other textured surface being formed by impact spray on a molded rubber latex film with liquid rubber latex droplets while the film is in uncured condition.

Abstract: A bed having a torque-compensated parallelogram lifting arm arrangement. The bed has a subframe vertically adjustable by the parallelogram lifting arm arrangement and thereby retains a level relationship at all height adjustment levels.An articulated mattress support surface is provided, which is formed by articulated pivotally interconnected head or back, seat, thigh and leg sections mounted on the level vertically adjustable subframe. The seat section is double-pivoted, and enables simple and effective Trendelenburg and Reverse Trendelenburg positioning independent of any position of the height-adjustable supporting subframe. The seat, thigh, and head sections are articulated by cam and cam follower drive arrangements. Selective pivot defeat means are provided to enable selective pivotal lowering of the thigh and head or back sections without pivoting the seat section, and independent of the supporting subframe position, enabling simple and effective hyperextension positioning.

Abstract: A unitary pilot-operated bi-directional cylinder lock valve and pressure-compensated flow control valve arrangement, having a common housing with internal porting connecting a pair of oppositely acting normally closed check valves operated to open by fluid pressure in one direction thereagainst on the inlet side and by a common free-floating inlet-pressure-responsive pilot piston therebetween. Also in the common housing and ported in line with each of the check valves are two pressure-compensated flow control valves which restrict fluid flow through the check valves as a function of flow pressure. The pressure-compensated flow control valves are also oppositely acting and each senses and acts to reduce fluid flow in response to pressure build-up in an opposite direction from that of the other.

Abstract: An operating table with geometrically compensated differentially movable load-sharing multiple hydraulic actuating cylinders is provided, which enables the employment of identical diametered tandem fluid connected cylinders through differential geometrical cylinder mounting and mechanical movement interconnection proportional to the cylinders' fluid-connected compression-to-tension end effective area ratio.

Abstract: An operating table having a longitudinally adjustably slidable patient supporting table top, the various top sections of which have radio-translucent patient-support panels which, together with the slide arrangement, enable positioning of any top sections for alignment and use with an X-ray photographic or image intensifier apparatus. The table top slide arrangement incorporates four spaced linear ball bushings in which a slide shaft is slidable to enable the desired ease of top positioning to a desired longitudinal position while tilted, flat, and evenly or unevenly loaded or unloaded.

Abstract: A hydraulic control valve arrangement for operating tables or the like, in which the table has both table top function control valves and associated hydraulic movement actuation cylinders and an elevate function valve and associated hydraulic elevation cylinder, and in which the elevate function control valve is operated by a separate control lever and is in overriding control of fluid supply pressure to the separate control lever-actuated table top function control valves, whereby either the elevate cylinder or a table top function actuation cylinder may be individually operated at one time, but not both the elevate cylinder and a table top function control cylinder, and whereby it is not necessary to switch a single control lever back and forth between elevate position and a selected table top function control position in order to selectively alternately effect elevation adjustment and a given selected table top function adjustment of the table top for desired table top positioning.

Abstract: A fluid dispensing arrangement for injecting liquid parenteral drugs or other liquids, including a syringe or cartridge with a needle-hub secured thereto, a plunger in the syringe or cartridge for effecting liquid discharge and injection, and a combination sealing and by-pass valve plug initially in a radially compressed sealing position at the forward end of the cartridge or syringe body or barrel and separating the liquid in the cartridge or syringe body or barrel from the needle-hub assembly, the valve plug being longitudinally forwardly movable to a by-pass discharge position within a by-pass chamber of larger diameter than the normal unrestricted and uncompressed diameter of the plug. The plug has tapered cruciform ends with corresponding circumferentially spaced by-pass grooves formed thereby at its opposite ends to aid in liquid by-pass therepast during liquid discharge or aspirating action.

Abstract: A packaged catheter arrangement having a soft and pliable latex rubber catheter for body orifice use and having its shaft slidably removably disposed within a relatively rigid tube sheath of plastic to form a catheter handling assembly which is enclosed as a unit within a peripherally sealed peel-apart dual sheet overpackage. The tube sheath is sealed closed at one end and the catheter preferably has a pre-lubrication coating on its insertion shaft and enclosed within the closed-ended tube sheath.

Abstract: A bed safety side rail arrangement which includes two opposite articulated side rail assemblies selectively pivotally movable from an upper safety position to a lowered position, as for patient transfer and handling and/or bedmaking tasks. The opposite side rail assemblies are readily removably secured to opposite sides of a bed, and desired structural rigidity is provided through the medium of tubular cross members or cross member assemblies which engage the side rail assemblies at their respective pivot connections.
