Definitions

  • Our invention has chiefly for its object the execution of means and arrangements for the distribution of a liquid having a predetermined grade and chiefly the distribution of sterile water, said means and arrangements satisfying better than hitherto the different requirements of practice.
  • Our invention consists chiefly in executing such arrangements wherethrough it is possible to feed in succession and as required a first liquid driving away or neutralizing the elements which might risk modifying the grade of a second liquid and then this second liquid which is that intended for use.
  • Said first liquid is a sterilizing water obtained preferably through chlorination or superchlorination while the second liquid is a water obtained through dechlorination of the first water as provided by active carbon.
  • the superchlorinated water is obtained inside a vat or the like container which feeds in parallel at least one point of utilization or else another container or the like part inside which the dechlorination is performed, which latter part may feed in its turn the first mentioned point of utilization.
  • the dechlorination apparatus is positioned underneath the sterilizing apparatus and the physical separation between the two apparatus is provided by an inner partition.
  • the circuits for the circulation and for the tapping oil? out of each of the two vats and apparatus are designed in a manner such that the liquids removed therefrom stay therein during a minimum time or else have travelled over useful paths the length of which is equal at least to a predetermined minimum.
  • the dechlorina-ting apparatus is fed from a vat containing a minimum provision of diluted bleaching liquid, said provision serving in particular for subjecting permanently said dechlorinating apparatus to the desired head.
  • said dechlorinating vat and the pipes which contain normally only sterilized water and no sterilizing water are located at a level lower than said point of utilization.
  • FIG. 1 is a diagram of a first embodiment of various features of our invention in the case of a distribution of Water sterilized through chlorination.
  • FIGS. 2 and 3 are diagrammatic views relating to two modifications of a preferred embodiment of an arrangement for producing and distributing sterile water in accordance with the invention.
  • FIG. 4 is a detail view relating to a modification of a section of FIG. 2.
  • the apparatus 2 which provides for the suitable mixing of ordinary water with a sterilizing reagent may furthermore be executed in various manners which do not form part of our invention.
  • We may thus resort to the arrangement disclosed in one of the French patents filed by the assignee: No. 721,156 filed on August 8, 1931, or 1,087,465 filed on August 3, 1953, or else in the copending French application filed on March 29, 1956, by the same applicant and entitled: Improvements in Means and Arrangements for the Execution of Measured Mixtures of at Least One Chemical Substance With at Liquid.
  • Said apparatus should in fact include a provision of water which is such that the duration of contact with the bleaching water may be long enough for the destruction of all the microbes before the water which has been sterilized and has thus become sterilizing flows out of the apparatus in the manner disclosed hereinafter.
  • the sterilizing water passes out of the apparatus 2 through a channel 4 out of which it is directed selectively into a pipe 5 and a distribution station illustrated by a tap 6 or else into a pipe 712 feeding a dechlorinating apparatus illustrated by the vat 7.
  • a pipe-closing member 8 is advantageously inserted in the pipe 4 while the two closing members 9a and 9b inserted in branch pipes 5 and 7b respectively allow connecting said pipe 4 with either of said branch pipes, i.e. the tap 6 and the vat '7.
  • vat 7 or the like dechlorinating apparatus may also be executed in various manners which do not form part of our present invention. It is possible for instance to resort to the apparatus disclosed in the French Patent 757,173 filed on September 10, 1932, and according to which the dechlorination is provided through active carbon mordanted with silver, which for-ms a safety step in the case where the arrangement is started operating under conditions where the sterilizing reagent is missing inside the apparatus 2.
  • the water which has been deohlorinated in said apparatus 7 may thus to be used directly on ones skin and it passes out of said apparatus through the pipe 7a which is connected with the tap 6 or with any other utilizing device, possibly along an indirect path through the pipe 5.
  • the pipe 7b for feeding the superchlorinated water extends downwardly inside the apparatus '7 near the bottom of the latter while the pipe 7a for the removal of the dechlorinated water starts from the upper end of said apparatus 7, this arrangement having for its object to prevent the apparatus 7 from emptying through a syphon action into the output pipe 7a or the like which would risk uncovering objectionably the active carbon inside the apparatus 7.
  • the dechlorinating apparatus 7 and the pipe 7a which is fed normally only with sterilized water and not with sterilizing Water are in this embodiment located entirely underneath the utilization tap or station 6. Consequently, in the case of a lack of pressure or even of a failure in the feeding of the arrangement, the air which may enter either the apparatus 2 or the utilization station 6 cannot enter the pipe 7a feeding sterile water or the apparatus 7. As soon as this pipe and this apparatus have been sterilized, they are not normally exposed to the risk of losing their sterile character. The case is not the same however for the other pipes and chiefly for the pipe 5 and also of the pipes 4 and 712. But the arrangement thus executed in accordance with our invention allows restoring the sterile character of said further pipes as will be disclosed hereinafter.
  • the manner of using the arrangement according to FIG. 1, is as follows: when it is desired to use the sterile water passing out of the apparatus 7 and which consequently cannot damage ones skin, it is necessary to first provide for a renewed sterilization of the pipe 5 and of the tap 6 when they have been liable to lose their original sterile condition, chiefly in the case of a hospital service. To this end, the closing member 912 is shut and the closing member ha and the tap 6 are opened; the sterilizing water flows out then through the latter.
  • the tap 6 is closed: the closing member db is then opened and the closing member 9a is closed.
  • the positions of 9a and 9b are interchanged.
  • the arrangements according to our invention may also form the object of various improvements.
  • the operations of the closing members 911 and 9b may be advantageously associated through a mechanism in a manner such that one of said members is closed when the other is open and reverse-ly. It is also possible for these associated operations to be controlled through a pedal 10 located in proximity with the utilization station 6 and connected with the pipe-closing memers 9a and 912 through a linkage 11.
  • FIGS. 2 to 4 show various modifications with reference to one another.
  • the sterilizing section of the unit executed in accordance with last mentioned embodiment is located at 12 in the upper part of a chamber 13 the walls of which are advantageously made of moulded plastic material while the dechlorinating section of said unit is located at 14 underneath the sterilizing section from which it is separated by a fiuidtight partition 15.
  • the latter is made advantageously of the same plastic material as the walls of the chamber 13 inside which it is fitted and glued fiuidtightly after the dechlorinating section has been formed.
  • the plastic material used for such walls may be in particular polyvinyl chloride, polyethylene or the like.
  • an opening covered by a plug or the like provides an access inside the dechlorinating section with a view in particular to allowing the renewal of the active material therein, which material is preferably constituted in this case also by active carbon.
  • the sterilizing and dechlorinating sections forming thus an independent unit, the pipes connected with the latter are designed as follows and the liquid moves therein also as described hereinafter: the tap .is fitted at the end of a pipe section 5 adapted to be fed either with sterilizing water through a pipe 70 in which may be inserted a suitable closing member dc or else with dechlorinated water, through the pipe 7d in which is inserted similarly a closing member such as 9b.
  • one of the closing members or 90! is closed while the other is open. It is advantageous to interconnect the control means for said closing members during operation so as to make them open selectively under the action of a linkage 11 adapted to be actuated through a pedal 10 which constitutes a single control member for the apparatus.
  • the pipe 7c may extend through the dechlorinating section 14- so as to remove the sterilized water out of the provision is above the said dechlorinating section, preferably from the lower part of said provision.
  • the sterilized Water may be collected until it is stopped automatically when the level of said provision 18 drops underneath the lowermost value considered as necessary for a sufiiciently long staying of the sterilized water which is being capped off inside the provision, said staying allowing the water to acquire in contact with the bleaching water or the like sterilizing liquid the desired microbicide and sterilizing properties.
  • the sterilized water is tapped oft at 19 at the lower end of the provision 18 through a syphon 20, provided with a vent 21 adapted to dewater the syphon or else we may resort to an arrangement having a similar effect for the case where the level drops underneath a predetermined minimum value.
  • the syphon extends downwardly down to a level 22 inside the lower part of the dechlorinating section 14, preferably towards one side of the latter.
  • the pipe 70 extends up to the point 7e inside the syphon above the partition 15. This last disclosed arrangement allows resorting to a single collecting syphon with a dewatering arrangement for feeding selectively as desired the dechlorinating section and the pipe 70.
  • the pipe 7d collects at 71 the dechlorinated water, preferably at a point in the upper part of the dechlorinating section and at a'distance from the lower end 22 of the syphon opening into said section so that the path followed by the sterilized water admitted at 22 into the dechlorinating section may be sufficiently long for a satisfactory dechlorination to be obtained.
  • a closing member 23 allows cutting off the admission of sterilized water out of the lower end 22 of the syphon into the dechlorinating section.
  • a disconnection of the common control, if any, of the closing members 9c and 9d allows opening these two closing members simultaneously; an output opening 24 intended for use during the original sterilization allows the original sterilizing liquid to pass directly out of the dechlorinating section.
  • the fluid circuit is closed through the opening 19 of the channel collecting the sterilized water so as to feed the latter through the pipe 70 into the pipe 7d and out through the upper opening 7 of the latter, which provides for the sterilization of this pipe 7d and finishes the sterilizing of the dechlorinating section 14 through which the sterilizing Water passes in a direction which is approximately opposed to the direction of flow of the sterilized water during operation, the sterilizing liquid being finally removed at 24 at the end of this operative sterilizing step.
  • the output opening 24 is provided with a safety device as required for it to remain closed during normal operation as perfectly as may be required.
  • the pipe section 7d extending between the closing means 9:! and the pipe is kept in proper sterile condition since the sterilizing water fed through 7c enters it in a satisfactory manner.
  • FIG. 3 shows as precedingly a sterilizing section 12 and a dechlorinating section 1 arranged to form in super position a unit similar to that illustrated with more detail in FIG. 2.
  • FIG. 3 shows as precedingly a sterilizing section 12 and a dechlorinating section 1 arranged to form in super position a unit similar to that illustrated with more detail in FIG. 2.
  • the pipes commumcatmg With said sterilizing and dechlorinating sections are positioned sideways instead of being located underneath the apparatus. Under such conditions: i
  • the tapping of sterilized water for feeding the dechlorinating section is performed through a similar syphon which is however independent of the former as shown at 1%, Ztib, 2112, said syphon being connected through the pipe section 26c with a lower opening 20d near the bottom and to one side of the dechlorinating section 14.
  • Closing means 23 are inserted in the pipe 20c in association with a temporary output opening 24a in the dechlorinating section so as to provide for the original sterilization of the pipe 71' and of the parts of the dechlorinating section located more particularly near said pipe.
  • FIG. 4 illustrates a detail modification in the execution of a liquid-removing syphon to be used in an embodiment such as that illustrated in FIG. 2.
  • the syphon 1920 with its dewatering vent 21 is replaced by a sort of bell 25 opening downwardly and provided in its upper part with a vent 21a or with an arrangement providing when required a similar dewatering effect.
  • a part of the channel 2! of FIG. 2 is then replaced by a tubular section 26:: extending coaxially inside the bell and over the pipe 22.
  • An arrangement for supplying sterile, non-irritating water comprising a chlorinating device, means to feed water to such device, a dechlorinating apparatus, a first means to feed chlorinated water from said device to said apparatus, a second means to feed water from said apparatus to a point of use, a third means to feed chlorinated water directly from said device to said second feed means, a single control member, and means operatively connected to said control member for selectively opening said third feed means to permit flow of chlorinated water to the point of use while closing one of said first and second feed means so as to prevent flow of dechlorinated water to such point or closing said third feed means to prevent fiow of chlorinated water to the point of use while opening the closed feed means to permit flow of dechlorinated water to such point.
  • said chlorinating device and said dechlorinating apparatus constituting a single unit, said chlorinating device being located on top of said dechlorinating apparatus, and a wall separating said device from said apparatus.
  • said means for feeding water from said device having at least a part thereof at a sufficient distance above the bottom of the device to ensure a minimum level of water in the device before water is fed to said apparatus.
  • said apparatus and at least a part of said second means being located at a lower level than the point of use.
  • said selectively operating means comprising valves to control said feeding means, said control member comprising a pedal connected to said valves for simultaneously controlling the same.
  • a chlorinating device a dechlorinating apparatus, an outlet pipe from said device, a connection from said outlet pipe to said apparatus, a second connection from said outlet pipe to a point of use, a
