Definitions

  • This invention relates to a device for regulating the 'quantity and composition of a mixture ot gases supplied under constant pressure, and is particularly applicable for use in administering gas for producing narcosis in surgical operations.
  • the quantity and composition of the mixture are regulated by two manipulating devices mounted close to each other in a manner which renders control easy and permits continuous variation of the quantity and composition.
  • the device comprises a separate valve for each gas.
  • These valves are connected at points, spaced apart, with a sliding block mounted so that it can be turned on a centre and capable of being displaced relatively to y this centre in such a manner that the said points can be brought into coincidence with the centre.
  • the centre may be an axis on which turns the frame wherein the block slides. The position of the block in relation to the centre determines the proportion in which the gases mix, while the angular position of the frame on the axis determines the quantity of the mixture.- When the point of connection of a valve with the block is coincident with the centre, that valve is closed; in any other position of the points the valves are open in a certain ratio.
  • A1 and A2 are the inlets for the two gases, which may be called G1 and G2 and are supplied under a pressure asconstant as possible.
  • the gases pass by Way of valves V1.and V2 to the mixing pipe C, connected' for instance with a inhaling mask.
  • the needles N1, N2 are connected by rods Ml, M2 respectively with the pins P1, P2 on the block S which slides in the frame R and can be displacedtherein by the hand-Wheel Q.
  • the pin P1 coincides with the axis D on which the frame turns, While in the other extreme position the pin P2 so coincides, as in Fig'l.
  • the arm H serves as a handle to turn the frame.
  • valve V2 As shown in Fig. l valve V2 is closed; it will remain closed when the frame R is turned on its axis to vary the passage through valve V1. Thus in this position of block S gas G2 cannot pass valve V2 and turning the frame will only vary the quantity of gas G2 which flows through pipe C.
  • a device for regulating the quantity and composition of a mixture of two gases each supplied under constant pressure comprising a separate needle valve for each gas, the needles of which are connected at points spaced apart with a sliding block mounted so that it can be turned around a center lying within the sliding block, the block being independently displaceable relatively to this center.
  • a device for regulating the quantity and composition of a mixture of two gases each supplied under constant pressure comprising a separate needle valve for each gas, the needles of which are connected at points spaced apart with a sliding block, a frame in which the block slides, an axle in the middle of the frame, the frame being movable together with the sliding block around this axle and the sliding block being displaceable relatively to the center lying Within the sliding block.
  • a device for regulating the quantity' and composition of a mixture of two gases each supplied under constant pressure comprising ⁇ a separate needle valve for each gas, the needles of which are connected at points spaced apart byrods and pins on a sliding block, a frame in which the block slides, an axle in the middle of the frame, the frame being movable together with the sliding block around this axle and the sliding block being 'displaceable relatively to the center lying within the sliding block.
