    Abstract: A disposable filter assembly is provided with a leakproof connection between the filter element and the filter housing to prevent external leakage, and a direct fluid connection between the interior of the filter element and one fluid line, thereby ensuring that unfiltered fluid will not by-pass the filter element and contaminate the downstream fluid line. In the preferred embodiment the fluid line connection and the filter element-housing connection are formed as an integral part of one filter element end cap. A vent also is provided to release air from the assembly when the assembly is installed and put onstream.

    Abstract: A timer is provided for alternately opening and closing an electrical circuit in accordance with a preselected time interval determined by the surface contour and rate of rotation of a timer cam. A preselected resilient contact blade engages the timer cam surface and is moved thereby into and out of electrical contact. A selector cam having an array of cam surfaces selects those of a matching array of resilient contact blades which are to engage an array of rotating timer cam surfaces for chosen time intervals.

    Abstract: A medicament administration system is provided that can be used once, and then discarded, and that can be used in conjunction with a syringe pump without danger of an embolism, comprising a twin valve T-connector, an air eliminator, and an administering means such as a needle for connection to a patient. A syringe can also be included as an integral part of the system and an administration system combining the syringe is a preferred embodiment. All interconnected components are sterile, and disposable. Another optional but preferred feature is an air spring or cushion that absorbs peak pressures arising from pumping action of the syringe plunger, and that is associated with the air eliminator at its upstream side. A visual flow indicator can also be included as a component.

    Abstract: 1,232,655. Reciprocating pumps. PALL CORP. May 21, 1968 [June 2, 1967], No. 24091/ 68. Heading F1A. A pump comprises a replaceable surgical-type syringe 65 supported by clips 75 on a base 50 and connected at its nozzle end 72 to a check valve assembly 78, e.g. with resilient lip valves 77. In the embodiment shown, the syringe piston is reciprocated by an electric motor-driven shaft 53 acting through wheel 52, pin 54, slot 59 and lever 58, 60. A carriage 61 slideable in a keyway 67 in base 50 transmits reciprocation from lever 60 to plunger 64, the effective stroke length being adjusted by a set screw 68 on carriage 61. Check valve assembly 78 is attached to syringe nozzle 72 by a push fit. Alternatively, a threaded or bayonet coupling may be used. In Fig. 1 (not shown), the plunger is reciprocated by a scotch yoke assembly and, the syringe and the check valve assembly are supported by clips on the base. In Fig. 2 (not shown), four syringes are disposed radially around a cam and have spring-loaded plungers engaging a cam. The mounting clips are arranged or are adjustable to receive syringes of different diameters to produce different pump outputs.
