Abstract: A lens disinfecting unit comprises a housing with adjacent compartments separated by a barrier wall. One compartment is adapted to receive the lens case for heating while the other compartment contains the heater and related circuitry. The barrier wall includes a heat sink which is insert-molded into the barrier wall to provide a water-tight seal such spilled liquid cannot leak from the lens case compartment to the heater compartment. The casing for the unit is made up of sections permitting sequential assembly, namely, two members are employed, one being a lid pivotally mounted over the heating well and the other being snap-fitted over the compartment containing the circuitry; and a third member serves to maintain the other two members in captive relationship.

Abstract: A disposable lancet for use in obtaining blood samples comprises a plastic housing and a resilient blade in a retracted position within the housing, the blade being bent in an arcuate form to provide a source of spring energy biasing the piercing edge of the blade toward an opening in the housing. A releasable trigger means retains the blade in its retracted position in the housing but is readily operable to release the blade to cause the part of the blade with the piercing edge to be driven through the opening a predetermined distance.

Abstract: A lens case comprises an outer case member and a drawer with "left" and "right" contact lens wells slidable on the case member. Removable caps are friction fitted over each well, the caps also being hinged to the drawer. A foldout lid with a mirror is adapted for disposition over the caps. The arrangement is such that as the drawer is shifted to the closed position in the case member, a wall of the case applies pressure to the caps through the mirror or through tapered ribs on the caps to maintain the caps sealed on the wells.

Abstract: Modular lens disinfecting device comprises a plastic housing with a heater and a heat sink lining a portion of the cavity and pressing against opposed caps on a lens case within the housing, thereby transmitting heat to opposed lens cavities within the lens case. A radial flange on the lens case body projects laterally from the housing when the lens case is inserted into the housing, thereby to facilitate manipulation of the lens case upon insertion into or removal from the housing. In making the lens case, the parting plane for the mold that forms the lens case body is positioned so that flash at said plane is precluded from projecting into either of the lens chambers.

Abstract: There is disclosed an improved molding machine and a system for utilizing said machine, wherein central sources of supply are used to provide the operating requirements for the machine, such as high pressure hydraulic fluid, compressed air, cooling water and electic power. The machine disclosed utilizes a stationary platen and a movable platen, with a novel mold clamping arrangement as an integral part of the movable platen assembly. In this regard, said movable platen includes a pair of relatively movable plate members, with a high pressure diaphragm interposed therebetween. On the rearward most plate member there is mounted latching means for fixing the position of said rearward plate member preparatory to pressurizing of the diaphragm. When pressurized, the diaphragm will force the forward most plate member toward the stationary platen to effect the desired preloading of the mold inserts carried by said platens.

Abstract: There is disclosed a basic lens case design, which is adapted for use in the storage and sterilization or disinfecting of contact lenses. The lens case design includes shallow, cup-like base and cover section. The base member and cover member include cooperating means for closure and a sealing structure to effect the retention of suitable sterilizing or disinfecting fluid therein. The base member has a partition defining a pair of similar compartments, each for receiving a lens and a quantity of sterilizing or disinfecting solution, the partition having a through opening formed therein permitting the free flow of solution and thereby maintaining substantially equal amounts of the disinfecting solution in the two pockets. In addition, the partition is spaced from this top surface a selected distance which is sufficient to prevent any pinching or damage to a lens.

Abstract: There is disclosed a disinfecting unit specifically designed for false or artificial dentures. The unit includes a base providing a cavity, having a support wall partially defined by a heater block. A receptacle for the dentures is provided, which is of sufficient size to accommodate dentures and a quantity of disinfecting solution. The support wall is spaced from the bottom wall of the base to accommodate the circuit and operating components, which include a re-set thermostat and a rockably mounted lever for operation of said re-set thermostat.

Abstract: The present disclosure relates to a testing tray for use in the conducting of a series of tests on a liquid specimen such as a blood or urine sample, with the results of the individual test being used to provide means for identification of a microorganism present in said specimens. The testing tray includes a plurality of test channels, which are of a generally U-shaped or reverse bend configuration, each channel including an entry portion and a testing portion comprised of one or more test chambers. The testing portions of the respective channels are closed by a transparent plastic sheet or strip which is affixed to the base in overlying relation to the various channels. The strip is sealed to the upper surface of the base intermediate the respective channels to effectively isolate one from the other, while leaving the entry portion of each channel open for the introduction of a liquid specimen therein.

Abstract: A container or case for use in storing and sterilizing corrective contact lenses is made up of a shallow cup-like base, a cap for selectively closing the open end of the base, and a lens basket arrangement situated in the base. The lens basket arrangement includes individual lens pockets which have a central hub and spaced staves radiating from the hub, the staves including substantially coplanar inboard portions adjacent the hub and abruptly upturned outboard portions for confining a contact lens element within the respective pocket and against laterally slidably extraction therefrom.

Abstract: The present invention relates to a thermal disinfecting unit for the disinfecting of a pair of contact lenses disposed within a lens case along with a quantity of disinfecting solution, wherein disinfecting is achieved upon the heating of the solution to a prescribed temperature. The unit as disclosed includes an outer casing made up of upper and lower assembled sections, with an internal heating arrangement disposed therein including a substantially planar lens case support surface. Aperture means are provided in the upper casing section and disposed in relation to the support surface to define a heater well for reception of the lens case. In one embodiment, the aperture means is defined by inwardly extending flange, with a gasket carried thereon, such that as the respective casing sections are drawn together, the gasket will firmly engage the planar support surface to seal the heater well from the interior of the unit.

Abstract: There is disclosed a contact lens disinfector unit for sterilizing contact lenses contained within a lens case. The disinfector unit includes a housing, a heating block within the housing for heating the lens case and the contact lenses therein to a sterilizing temperature, and a tray pivotally mounted to the housing. The tray includes a lens case receiving opening adapted to receive and support the lens case. The tray is arranged to pivot or swing between an open position disposing the opening outside of the housing to permit a lens case to be placed therein, and a closed position disposing the opening above and adjacent to the heating block within the housing to bring the lens case into heat transfer contact with the heating block. The disclosed embodiment also includes a latch for releasably locking the tray in the closed position, which latch will co-act with the tray to urge the tray towards the open position after disengagement of said latch.

Abstract: A contact lens disinfector has a molded plastic casing with wells at opposite ends for receiving the respective lenses and the disinfecting solution. Caps are removably threaded onto the casing over the wells. A thermistor heater is embedded in the casing between the wells to provide a low temperature (60.degree. C. -80.degree. C.) heater for the solution for an extended heating cycle, thereby to inhibit deterioration of the lenses due to loss of transparency.
