Definitions
- the invention relates to an apparatus for preventing microorganism contamination from outside en- vironment intowater or other fluids that have been previously sterilized to assure that they are micro ⁇ organism free even after substantial outside surface bacterial contamination of the apparatus.
- This contami ⁇ nation may arise from handling and/or from environmental factors.
- this patent describes an apparatus for the continuous production of high-purity water including a distillation flask, a carboy and a condenser unit.
- a filter is provided between the atmosphere and the interiors of the flask, the carboy and the condenser unit to remove airborne bacteria from entering the apparatus.
- the open parts are inter ⁇ connected with inert flexible tubing pieces.
- a two-way stopcock allows high purity water to be removed from the carboy.
- the bacteria generally are either airborne or grow on human skin and transfer on to the valve during handling.
- Various devices have been proposed for preparing sterile liquids.
- U.S. Patent 2,456,152 de ⁇ scribes a device wherein the outlet faucet is continuously bathed in steam.
- U.S. Patent 2,537,774 relates to a device that utilizes ultraviolet radiation to sterilize liquids.
- French patent 1,101,643 uses a combination of ultraviolet and infrared radiation to prepare sterile liquids.
- Figure 1 is a front perspective view of the preferred embodiment of the invention.
- Figure 2 is a front perspective view of the lower portion of the faucet of figure 1.
- Figure 3 is a cross sectional view of the lower portion of the faucet of figure 1, also showing details of the light source.
- FIG. 4 shows another embodiment of the invention.
- FIG 1 shows a faucet attached to a conduit 10 designed to be readily attached to and detached from a source of sterile water (not shown) .
- An elbow 18 is threadably attached to one end of the conduit 10 at 19.
- a short conduit 20 is attached to an elbow 18 at the joint 21.
- a nipple 12 having corrugations 23 thereon for ease of attachment to a rubber or plastic tubing is threadably attached to the conduit 20.
- a lock nut 22 secures the faucet if it is attached to a support.
- the other end 24 of the conduit 10 is threadably attached to the faucet structure 25.
- the faucet per se is commercially available and is not part of the invention.
- the faucet 25 includes a toggle member 15 threadably attached to a handle 16.
- the handle 16 moves from the open to the closed position about a pin 11 to open and close the faucet.
- the invention resides in the modification of this commercially available faucet to include an ultraviolet source 13 attached by wire 40 to a control unit (not shown) .
- the ultraviolet source 13 attached by wire 40 to a control unit (not shown) .
- the water passing through the faucet 25 may also be contacted by ultra-
- the water passing through the spout 14 is thus sterile at all times.
- the faucet 25 is shown in cross section and consists of a threaded portion 24 designed to be attached to the conduit 10 leading to a conduit 31, which leads to a water receiving chamber 32.
- a dia- phragm is positioned in the seat 33 and is moved from the open to the closed position by movement of the han ⁇ dle 16 shown in figure 1.
- a conduit 34 connects the chamber 32 to the channel 35 in the spout 14.
- the channel 35 has a narrow area at 36 and an enlarged area at 37. .
- the light source 13 has an upper portion 38 that contains electrodes (not shown) attached to a control unit 39 by means of a wire 40.
- the lower por ⁇ tion of the light source 13 consists of a quartz tube 41 filled with mercury vapor.
- a plastic collar 42 is machined to fit into the enlarged area 37 of the spout 14.
- FIG. 4 shows another embodiment of the invention.
- the base 50 is attached to a conduit 51 and extends to the toggle valve member 25 described in detail with reference to figures 1 and 3.
- a spout 52 is detachable connected by means of a collar 53 to the L shaped conduit 54.
- the forward end of the conduit 54 terminates in a conduit 55.
- the conduit 55 has an enlarged portion 56, and a restricted portion 57.
- An ultraviolet source 13 is inserted in a stopper 58.
- the ultraviolet source 13 contains electrodes (not shown) attached by means of the wire 40, to a con ⁇ trol (not shown) .
- the lower portion of the ultraviolet slight source 13 consists of a quartz tube 41 filled
- the ultra ⁇ violet lamp 13 is positioned in the faucet 25 as shown in the figures. Water passes thru the conduit 10 into the faucet 25.
- the faucet handle 16 moves the toggle member 15 to move the diaphragm 33 of figure 3 so that water can flow thru the conduits 31 and 34 into the conduit 35.
- the ultraviolet light source is energized by the control unit 39 and emits ultraviolet light thru the quartz tube 41 positioned in the conduit 35 in figure 3.
- the water in conduit 35 (in figure 3) is protected by the ultraviolet light.
- the control unit 30 controls the time the ultraviolet light is energized.
- the ultraviolet light is energized periodically for short period of time to prevent contamination of the spout 14 from outside sources.
Abstract
Dispositif empechant la penetration de micro-organismes de l'exterieur dans des systemes clos steriles contenant de l'eau sterile ou d'autres fluides pour une utilisation generale ou biomedicale.A device that prevents the penetration of microorganisms from the outside into closed sterile systems containing sterile water or other fluids for general or biomedical use.
