Definitions

  • breathing apparatus such as ventilators using fluidic systems as control and power sources
  • different modes of operation are often incorporated into the same apparatus.
  • a breathing system which incorporates control, assist and assist/control modes
  • in the control position the patient is being breathed mechanically
  • in the assist position the patient triggers the apparatus
  • in the assist/control position both the mechanical and patient assist modes are in operation.
  • FIG. 1 is a sectional view of the fluidic switch of this invention.
  • FIG. 2 is a front view of the fluidic switch of FIG. 2 through the section 22.
  • this invention provides a fluidic selector switch having a plurality of positions which are independently activated. It comprises a switch body housing a plurality of valve cores, e.g., tire valve cores which are activated by the depressing action of a spring activated ball.
  • a fluidic selector switch having a plurality of positions which are independently activated. It comprises a switch body housing a plurality of valve cores, e.g., tire valve cores which are activated by the depressing action of a spring activated ball.
  • a fluidic selector valve having a switch body 11 and a valve selector 12.
  • the switch body comprises a valve chamber 13, a valve 14, e.g., a tire valve in the chamber, a valve activator l6, e.g., a pin actuator in the chamber, and an open port 17 in fluid communication with the valve chamber via conduit 18.
  • a valve chamber, valve and communication conduit are illustrated, this is not a limitation of the invention as it is understood that 2, 3, 4 or more valve chambers valves and interconnecting conduits with the open part may be utilized, and that a description of one valve chamber, valve and valve actuator is all that is necessary for an understanding of the invention.
  • the valve selector 12 comprises a knob 19, a ball 21, a spring 22 and a ball chamber 23 for containing the ball and spring.
  • FIG. 2 shows three valve chambers 13, the open port 17, and the interconnecting conduits 18.
  • the ball chamber 23 is positioned (aligned) over the selected valve chamber and the ball actuated by the spring compressed pin actuator 16 which compresses (opens) the valve 14, thus releasing fluid, e.g., air, oxygen, and the like from a source, not shown, through conduit 26 past the valve and into conduit 18 to the open port 17.
  • fluid e.g., air, oxygen, and the like from a source, not shown
  • the valve selector is turned to that mode, thus removing the ball from the pin actuator and closing the valve 14 to shut off the fluid supply to the open port.
  • the valve contacting that mode is open as described above and fluid from it is then released to the open part.
  • the switch body is preferably a two piece body with one port 27 containing the tire valve.
  • the second part 28 containing the valve actuator and conduit 18.
  • the parts 27 and 28 may be secured together by conventional means e.g., a screw 29.
  • valve selector is held in slidable communication with port 28 of the switch body by a lock nut 31.
  • a fluidic selector valve device comprising in combination a switch body, a plurality of valve chambers in the switch body, a fluidic valve removably secured in each of the valve chambers, a valve actuator slidably received in each of the valve chambers, a port in the body in fluidic communication with the valve chambers, a rotatable valve selector slidably secured to the switch body, the selector comprising a housing and a chamber in the housing with a ball and spring in the chamber, the selector when rotated aligning the ball and spring housing such that the spring actuates the ball to compress the valve actuator to engage and open the valve to emit a fluid to the port.
