Definitions

  • New disposable endoscope valves and methods are provided that reduce or eliminate the risk of contaminating the endoscope and reduce or eliminate the risk of infecting the patient. Further, new disposable endoscope valves and methods are provided that allow the disposable valve to function better by providing an improved seal using a lubricant that allows a more uniform fit in the valve chamber or channel and better suction, and/or flow of air and water.
  • Various embodiments provide disposable valve assemblies configured for use with a FujiFilmTM endoscope and are discussed herein, including manufacturing processes for the same.
  • the new disposable endoscope valves in some embodiments, can have a lubricant.
  • this disclosure provides a disposable suction valve assembly configured for use with an endoscope.
  • the disposable suction valve assembly comprises a stem, comprising a proximal end and a distal end and a first opening disposed along a longitudinal axis of the stem, the stem comprising a thermoplastic material and a second opening transverse to and intersecting with the first opening, the second opening of the stem partially extending through the stem and a surface opposite the second opening comprising a projection extending from the stem.
  • this disclosure provides a method for manufacturing an air/water disposable valve assembly configured for use with an endoscope, the method comprising separately molding the valve stem, cap and spring stanchion, wherein the stem comprises a proximal end and a distal end and a first opening disposed along a longitudinal axis of the stem and extending from the proximal end to or adjacent to the distal end of the stem, the stem comprising a second opening transverse to and intersecting with the first opening, the second opening of the stem adjacent to the distal end of the stem and extending through the stem.
  • FIG. 5E illustrates a bottom view of the distal end of the umbrella stem design of an embodiment of a disposable air/water valve for use in endoscopes
  • FIG. 15B illustrates a perspective view of another embodiment of a boot for use with a disposable air/water or a disposable suction valve in endoscopes
  • FIG. 16F illustrates a cross-sectional view along plane BB of FIG. 16E.
  • the disposable air/water valve 100 also contains aligners 114, 116, 118 and 190 (H4a, H6a, H8a, l20a, H4b, H6b, H8b, l90b).
  • Stem 101 (lOla, 10 lb) further contains a transverse hole 180 (l80a, l80b).
  • These ridges and/or grooves can be rigid or they can be flexible. In the embodiments shown, due to the ridges and/or grooves the main stem has a varied diameter, where the diameter is greater by the ridges and the diameter is smaller by the grooves. This configuration allows gaskets or seals to be inserted or overmolded into the grooves.
  • Lubricant 1000 can also be disposed on the stanchion or spring stanchion 200 and spring.
  • lubricant 1000 also contains an antimicrobial agent.
  • disposable air/water valve 100 can contain the antimicrobial as part of the stem, spring stanchion, seal, and/or spring.
  • the antimicrobial agent can be a coating on the components or homogenously disposed in the material that the stem, spring stanchion, seal, and/or spring is made from.
  • Umbrella shaped gasket 120 is an elastomeric valve component that is an umbrella shaped sealing disc. This elastomeric component can be used as a sealing element in a backflow prevention device such as a valve.
  • a backflow prevention device such as a valve.
  • the convex umbrella shaped disc 120 flattens out against the valve seat and absorbs a certain amount of seat irregularities and creates a certain sealing force.
  • the umbrella shaped sealing disc will allow forward flow once the head pressure creates enough force to lift the convex diaphragm from the seat and so it will allow flow at a predetermined pressure in one way and prevent back flow immediately in the opposite way.
  • the monolithic stem (one piece) comprises a plurality of ridges and grooves that are, in some embodiments, the same material as the stem.
