| 221 | Rinsing apparatus for contact lens cleaning system | US753323 | 1985-07-09 | US4653519A | 1987-03-31 | Rowland W. Kanner |
| A rinsing apparatus is provided for a contact lens cleaning system. This rinsing apparatus comprises a container for receiving a quantity of rinsing fluid, receptacles for receiving contact lenses and an agitator mounted in the container for a compound agitating motion and coupled to the receptacles for agitating the receptacles. A base unit includes a platform for mounting the container in a stationary position and a drive assembly for driving the agitator to achieve the desired compound agitating motion. Advantageously, this drive assembly is operatively coupled with the agitator only by a magnetic coupling arrangement, obviating the need for any mechanical connection or coupling therebetween, or for extending any rotating members through the container. | ||||||
| 222 | Apparatus for cleaning and sterilizing soft contact lenses | US602512 | 1984-04-20 | US4582076A | 1986-04-15 | Jacques E. Prat |
| An apparatus for cleaning and sterilizing soft contact lenses comprises a disinfection unit and a control unit. The disinfection unit comprises a receptacle for selectively containing a cleaning liquid and a sterilizing liquid, and a lens holder having perforate lens compartments. The lens holder is removably mounted in the receptacle and rotatable therein. The rotation of the lens holder effects enhanced cleansing action by turbulent flow of the cleaning liquid over the lenses. A heater is preferably mounted on the control unit in intimate heat transfer relation with the disinfection unit when the units are secured together (e.g. with permanent magnets) for heating the sterilizing liquid in the receptacle. The control unit controls the heater for providing alternating high temperature periods (not greater than about 60.degree. C.) and lower temperature periods for sterilizing the cleaned lenses. | ||||||
| 223 | Method for disinfecting and cleaning contact lenses | US316937 | 1981-10-30 | US4382824A | 1983-05-10 | Frank E. Halleck |
| A process is described for cleaning and disinfecting a soiled contact lens in a single unit operation. The soiled contact lens is immersed in a cavitation-supporting saline solution which is at ambient temperature. The lens is then subjected to ultrasonic energy which is transmitted through the solution at a frequency of between 62 and 72 kHz and an intensity of between 0.8 and 2.0 watts per ml. of solution. This procedure causes substantially all of the soil to dislodge from the lens before the combined elapsed time and temperature conditions within the solution produce any substantial protein denaturation on the lens. Ultrasonic energy is transmitted continuously through the solution at the same frequency and intensity ranges so that the temperature of the solution does not exceed about 65.degree. C. but the total elapsed period of the ultrasonic energy transmission, not to exceed about 20 minutes, must be sufficient to effect the disinfection of the lens. | ||||||
| 224 | Soft contact lens apparatus | US91317 | 1979-11-05 | US4277172A | 1981-07-07 | William D. Richards |
| Improved apparatus for transporting and positioning a contact lens immersed in a liquid for inspection is disclosed. The device has a plurality of supporting surfaces and a weight to biase the lens against the surfaces during immersion and prevent unintentional motion of the lens in the liquid during inspection. | ||||||
| 225 | Contact lens cleansing apparatus | US928751 | 1978-07-27 | US4187574A | 1980-02-12 | Richard J. Wrue |
| An apparatus for the cleansing of contact lenses comprising a housing for containing a lens divided into a top portion and a bottom portion. The top portion may be joined or removed from the bottom portion. In addition, the top portion is movable while joined with the bottom portion and vice-versa. Within the top and bottom portions are scrubbing pad means which are used to scrub a contact lens when the top portion of the housing is moved in relation to the bottom portion. An offset dome is built into the bottom portion which causes the lens to migrate within the housing during scrubbing, thereby thoroughly cleansing all portions of the lens. | ||||||
| 226 | Ultrasonic cleaning and sterilizing apparatus | US489964 | 1974-07-19 | US3973760A | 1976-08-10 | Iben Browning; Robert E. McClure |
| Apparatus for the ultrasonic cleaning and sterilization of soft contact lenses and fenestrated hard contact lenses at a temperature that is low relative to that of pasturization is disclosed. A transducer element is electrically connected to a source of oscillating current to produce mechanical oscillating motion. A capsule is provided which is adapted to contain a biologically inert solution in which the soft contact lenses are immersed and the capsule is then hermetically sealed but not pressurized. Apparatus is provided for demountably connecting the capsule to the transducer element so that a continuous spanwise mechanical coupling is provided from the transducer to this surface of the capsule. A tuner element may be interposed in the connecting apparatus. The lower surface of the capsule is vibrated at a preselected ultrasonic frequency to induce ultrasonic waves in the solution in the capsule and to heat the solution in a controlled manner to clean and sterilize the soft contact lenses therein. The solution in the capsule is sterilized as well, giving rise to alternative uses of the instant invention. | ||||||
| 227 | Methods for cleaning and bleaching plastic articles | US40575173 | 1973-10-12 | US3908680A | 1975-09-30 | KREZANOSKI JOSEPH Z |
| Plastic articles are cleaned by successively immersing them in two aqueous solutions, with each solution containing an active oxygen yielding per compound and preferably a chelating agent. One of the solutions is formulated to be acidic and the other is formulated to be basic. After the article is removed from the last solution, it is treated with a non-ionic cleaner and then rinsed with water. The method produces a remarkable cleaning and bleaching action on dirty, discolored plastic compositions. This is particularly apparent when the method is applied to contact lenses.

| 228 | Contact lens cleaning and storing composition including nonionic surfactant, benzalkonium chloride and Na{hd 3{b EDTA | US27980072 | 1972-08-11 | US3882036A | 1975-05-06 | KREZANOSKI JOSEPH Z; PETRICCIANI JOHN C |
| A contact lens cleaning, storing and wetting solution is provided for cleaning, storing and wetting flexible silicone contact lenses. The solution comprises a poly(oxyethylene)poly(oxypropylene) block copolymer having a molecular weight between about 1,900 and 15,500, a water solubility in excess of about 10 grams per 100 ml., a cloud point in 1% aqueous solution above about 30*C., and a Foam Height in excess of 30 mm; a microbial growth inhibitor, such as benzalkonium chloride; purified water; and a sufficient amount of at least one essentially neutral, water-soluble compatible salt to provide a solution salt content equivalent to about 0.5 to 1.8% sodium chloride. The solution can also contain disodium or trisodium ethylenediamine tetraacetate and a polymeric viscosity building agent, if desired. A cleaning composition for polyhydroxylated alkyl methacrylate soft contact lenses includes the above poly (oxyethylene)poly(oxypropylene) block copolymer and sorbic acid as a germicidal ingredient.

| 229 | Ultrasonic/chemical cleaner for contact lenses | US33582273 | 1973-02-26 | US3871395A | 1975-03-18 | MURRY EDWARD J |
| Apparatus for ultrasonically and chemically cleaning contact lens of all types which utilizes a relatively high ultrasonic frequency at an intensity level which is higher than normally would be considered for such small items, so as to cause the cleaning fluid to be emulsified and reach molecular bond-breaking levels, and so as to cause intense cavitation. The cleaning fluid is raised to a high temperature for medical sterilization. The cleaning device includes automatic control so that the lens may be automatically cleaned, and the cleaner will then disable itself.

| 230 | Contact lens washer with lens storage | US3623492D | 1969-09-24 | US3623492A | 1971-11-30 | FRANTZ DOLPH G; JOSEPH WILLIAM |
| There is a container to hold lens washing fluid. A member is rotatably mounted in a lidlike member mounted on this container. This rotatably mounted member has a lower part that removably receives a perforated case for a contact lens. Mounted on the lidlike member is a turn knob that through gearing mounted in the lid turns the rotatable member carrying the lens case so that washing takes place of the contact lens carried in the perforated case. The container has spaced-apart depending legs between which a lens case carrier may be stored. The turn knob has two compartments with hinged tops for storage of right and left contact lenses.
