Abstract: An analytical specimen cup (10) has outer and inner partitions (26, 34) in a lid (14) thereof, with the outer partition being flexible and transparent and the inner partition having a valve (46) comprised of a frangible portion (50) of the inner partition. A chemical test strip (24) is mounted in a test space (42) between the outer and inner partitions and a fluid specimen in the cup can be introduced to the chemical test strip in the test space by manipulating the frangible valve (46) to break it open via the flexible outer partition. The inner partition is formed as a one-piece lid main member (22) with most of the rest of the lid whereas the outer partition is mounted to cover an indentation (30) into a top surface of the lid main member to define the test space in the indentation.

Abstract: A crutch tip assembly (12) comprises a solid base (14) having substantially vertical side surfaces (18, 20, 54, 56) and outwardly, downwardly tapered front and rear surfaces (22, 24, 51a, 51b) with convex bottom surface (26, 52) forming an approximate arc elongated in a direction approximately parallel to the side surfaces. A laterally outwardly protruding lip (28, 50) is positioned adjacent the bottom surface near bottom edges of the side, front and rear surfaces on which a resilient boot (16, 70) having the shape of a rocker is mounted. The resilient boot defines a mounting cavity (36, 72) for snugly receiving the solid-base bottom surface and the lip for holding the boot on the solid base. An elongated, centered, arch-shaped groove (38, 74) extends along a bottom surface of the boot. The solid base is attached to a single support 33 at a lower end of a crutch frame 34 by means of a tongue (30, 68) and groove (32) joint and alternately an adhesive or other affixing means.

Abstract: An improved medical lavage apparatus (10) includes guide/lock/stop tabs (122) which are inserted through a medical lavage syringe housing (20) into irrigation and aspiration bores (30, 34) thereof for engaging longitudinal ribs (68a-d, 69a-d) of irrigation and aspiration plungers (24, 26) to prevent their rotation and a circumferential latch rib 134a of the aspiration plunger for locking the aspiration plunger in an inserted position. The tabs also contact end circumferential ribs 70' of the plungers for providing stops to prevent the plungers from being removed from their respective bores. The tabs comprise two legs (126) which straddle the longitudinal ribs, with a longitudinal rib 68a of the aspiration plunger having a notch (140) at the tab in the aspiration bore to allow rotation of the aspiration plunger when it is in the inserted position for engaging the legs with the circumferential latch rib.

Abstract: An indwelling urethral catheter system and method of its use involve a drainage shaft (16) mounted in a urinary tract (24) having an externally-operated, normally-closed, fluid valve (38) mounted therein near the meatus (22) of the urinary tract. A removable insertion conduit assembly (12), separate from the catheter drainage shaft, is for extending from outside the body, through the meatus of the urinary tract to plug into the proximal end of the catheter drainage shaft and impinge on the valve for holding it open to allow free drainage through the valve. Once the insertion conduit is removed from the urinary tract it no longer impinges on the valve for holding it open and the valve is thereafter normally closed unless opened by application of force from outside the body.

Abstract: A medical lavage apparatus (10) for body cavities, comprises a housing (20) having parallel irrigation and aspiration cylinders (28, 32) with plungers (24, 26) extending in bores thereof from a first end and aspiration and irrigation check valves positioned in parallel, smaller, offset, valve cylinders (46, 48) located at second ends. A septum (50) formed of intersecting semi-circular-in-cross-section baffles joins the adjacent outer ends of the irrigation and aspiration check valve cylinders so as to allow full fluid streams flowing from these outer ends to flow together at an angle. An oblong-in-cross-section, funnel-shaped, common exchange tube (22) is attached to the housing surrounding ends of both the irrigation and aspiration check valve cylinders and the septum. Inlet and outlet ports (42 and 44) are respectively positioned on the sides of the irrigation and aspiration cylinders with appropriate check valves located therein for coupling respectively to supply and waste containers (12, 16).

Abstract: An indwelling urethral catheter (10) includes a flexible catheter drainage shaft (18) defining a drainage canal with a valve (32) mounted therein. The catheter is mounted in a urethral canal by means of a bladder-located Foley-type balloon (22) and an inflatable balloon lead shaft (24) which extends along the catheter drainage shaft. The valve (32) is normally biased to a closed position, but is actuatable to an open position by external hand manipulation of a penis in which the catheter is implanted. The catheter (10) also includes a discardable sleeve (12) which is severably attached to the distal end of the catheter (10), on the proximal side of the balloon (22). After insertion into the urethra, the balloon (22), and its lead shaft (24) are inflated through a "basketball" type contraction valve (44).
