  • This invention relates to a device for separating a main gaseous fiux into proportional secondary fluxes independently of the total output, and also to its application to an evaporator vessel for liquid anaesthesic products. 1
  • the loss of pressure produced by the device is of the order of a few millimiters of water for a total output of p 50 liters/minute.
  • the separation of the initial flux into two fluxes remains proportional as a function of the variation in the total output.
  • the device according to the invention consists essentially of an enclosure subdivided into at least three contiguous chambers by a wall perforated with holes having the same cross-sectional area and opening on one side into a single main chamber of said enclosure and on the other side into at least two secondary chambers of said enclosure.
  • the total flux is introduced into said main chamber and the fiux is expelled from each one of said secondary chambers.
  • a suitable shutter controlled from outside ofthe enclosure and housed in said first chamber permits of masking certain holes connecting said main chamber to one of said secondary chambers and possibly of simultaneously uncovering certain holes connecting said main chamber to either of said secondary chambers.
  • the proportions of the secondary outputs can be varied at will.
  • This arrangement is suitable for use in an evaporator vessel for liquid anesthetic products; as the liquid must be administered at very low concentrations, it is necessary to divert one fraction of the vector gas towards the evaporator where it is saturated into anaesthetic vapor, and to redirect it towards a mixing chamber in which the desired final concentration is obtained.
  • the present device is advantageous, in the case of such an evaporator, in that the patient can breath effortlessly through this evaporator and without any addition of compressed gas.
  • the device illustrated consists of an enclosure 4 subdivided internally by a partition 5 perforated by a relatively great number of holes 6 having parallel axes which open on one side into a single chamber 1 and on the other side into a pair of suitable shutter 8 is provided for covering or masking in chamber 1 the holes corresponding to chamber 2 and at the same time uncovering or unmasking an equivalent number of holes opening into the other chamber 3 for the purpose of varying the relative proportion in the outputs of the two fluxes while preserving a constant loss of pressure for a predetermined total output.
  • the total flux is introduced by means of a pipe 9 into the chamber 1 and the secondary outputs are delivered yi a ducts 10 and 11, respectively.
  • the fresh gases penetrate into chamber 1 through a filter 12.
  • the partition wall 5 is perforated by about 100 of small holes 6, about 0.5 mm indiameter, causing this chamber 1 to communicate with an annular secondary chamber 2 connected directly to the outlet 10, and about half a score of identical holes 3 6a causing said chamber to communicate with a central secondary chamber 3 connected via a duct 13 to a saturator 14 of anaesthetic product connected via another duct 15 to the rear portion of the secondary chamber 2;
  • an input shutter-8 controlled from the outside by means of a button 16 and an axial rod 17 permits of covering or masking a predetermined number of holes 60;
  • an output, or delivery shutter 18 rigid with rod 17 permits of covering or masking the outlet of duct 15 and therefore preventing the evaporation of the anaesthetic product when the apparatus is inoperative.
  • a narcosis apparatus to be mounted between supply means delivering respirable gas and application means comprising a primary chamber provided with inlet means attached to said supply means, a pair of coaxial secondary chambers, a partition for separating said primary chamber from said pair of secondary chambers, said pair of coaxial secondary chambers comprising an annular secondary chamber communicating with said primary chamber through a first series of holes formed in said partition and provided with outlet means attached to said application means and an axial chamber communicating with said primary chamber through a second series of holes formed in said partition, an inlet control shutter for controlling the ingress of respirable gas into said secondary axial chamber, which is rotatably mounted in said primary chamber, external control means for setting said shutter in any desired position from a position in which all the holes of said second series are obturated to a position in which all the holes of the second series are uncovered, a saturator of liquid anaesthesic product, disposed beneath said primary chamber and said secondary annular chamber, said saturator of liquid anaesthesic product,
