Definitions

  • the body and the other is on the end of a flexible liquid feed B65b 3/ 18 conduit attached to a filler bottle.
  • the conduit is an air tube [50] Field of Search 141/285, within a liquid passage forming tube and the said body part 301, 308 (Earles), 309, 302
  • This invention relates to apparatus capable of mixing the vapor of a volatile liquid anesthetic with a gaseous fluid, such as air, oxygen, or nitrous oxide, or a combination thereof, all
  • the apparatus should be used only for one type of volatile anesthetic although it is known for the apparatus to be used for different types with a cleaning operation between the changes.
  • this invention is concerned with ensuring that only a given type of liquid anesthetic can be poured into the apparatus from a supply container which is usually a glass bottle, and it is the main object of this invention to provide a safety-type filling system and means for this purpose.
  • a filling system for volatile liquid anesthetic apparatus including an inlet device on the wall of the liquid receiving body of the apparatus, an inlet opening in said device, a separate conduit having at one end an outlet member to enter said opening and at its other end a cap connection to be secured onto the neck of a bottle, air and liquid passages through the conduit" and its ends to facilitate the flow of liquid from the bottle into said body, said conduit outlet member and its receiving inlet opening in said device being complementary in a manner that ensures only the cor- .rect type of member can be fully inserted and thus a correct type of liquid introduced into the apparatus.
  • the invention includes an inlet device forming part of the wall of the aforesaid body, said device including means for retaining the aforesaid outlet member of the conduit and means for closing the opening when the member is withdrawn.
  • the said device may incorporate a drainage control valve and outlet passage. Said outlet passage may terminate in an outlet opening adapted to receive the aforesaid conduit outlet .member for draining liquid from the body into a bottle.
  • the conduit outlet member may have an outlet hole and an inlet hole for separating the air and liquid passages. Moreover, said member may have a slot to collaborate with a location ,peg in the inlet opening to receive the member.
  • FIG. 1 is a sectional elevation of the liquid anesthetic filling device on a vaporizer
  • FIG. 2 is a sectional elevation of the conduit and bottle for connection to the filling device; and FIG. 3 is a sectional elevation of the filling device and conduit in engagement.
  • a filler block .1 is secured to the sidewall of the body 2 of liquid anesthetic apparatus to provide means for the introduction of liquid anesthetic 3.
  • This block incorporates an inlet opening 4 of cross-sectional shape (it may be rectangular or other shape) which is complementary to an outlet member 5 on the end of a flexible conduit 6 which incorporates air and liquid flow passages 7 and 8 leading respectively to and from openings 6a and 7a in the member.
  • the arrangement is such that only an outlet member 5 of the correct shape and size or other formation, can enter fully into the opening 4.
  • the member 5 has a slot 9 to register with a location peg 10 which projects into the opening 4 at a predetermined point.
  • a liquid feed-air outlet passageway 11 leads from feed and air holes 12 and 13 leading from the said opening 4 to communicate with an opening 14 in the wall of the body of the apparatus for introducing liquid thereinto.
  • a locking screw 15 is provided in the head of the block 1, and such head may be a separable part of the block.
  • the other end of the conduit 6 is in the form of an internally screw-threaded cap 16 to be screwed on to the neck 17 of a known formof liquid containing bottle 18.
  • the arrangement is preferably such that there is no need to redesign the formation ,of the bottle neck 17 but the cap can be arranged to fit only the neck of a bottle containing a given drug.
  • the bottle is closed by a removable rubber or other flexible seal or disc normally enclosed by a screw-on cover cap.
  • a removable rubber or other flexible seal or disc normally enclosed by a screw-on cover cap.
  • Such cap and disc can readily be removed for the location of the conduit cap 16 incorporating a flanged conduit connection element 19 which has a part 20 for locating the air tube 7.
  • a sealing washer 21 is located between the element flange and the neck 17 to provide a liquidand airtight seal.
  • the conduit outlet member 5 can be pushed into the aforesaid inlet opening 4, secured by the screw 15 and the bottle inverted for liquid to flow therefrom into the body 2 to a given level.
  • air flows out through the passageway 11, the hole 13, opening 7a and passage 7 into the bottle 18.
  • the conduit is removed and a closure plug 22 (or other means) with a gripping knob 23 used to close the inlet opening 4.
  • This plug has a slot 24 to register with the pin 10 and it closes the two holes 12 and 13.
  • the aforesaid supply block 1 includes a liquid drainage section 25.
  • a cranked (or other) drainage passage 26 leads from the bottom of the feed passageway 11 and into a small valve chamber 27 controlled by a valve 28 in a screwthreaded bore 29.
  • a further passage 30 leads from the chamber to a drainage outlet opening 31.
  • the latter may be a single opening for the outflow of liquid when the valve 28 is released (screwed back) but such outlet opening is preferably of the same formation as the aforesaid inlet opening 4 with a location peg 32 so that the conduit member 5 can be inserted thereinto for draining liquid back into a bottle 18 through the same (or another) conduit 6.
  • This lower section 25 of the block 1 may be a detachable part from the main block. Moreover, if so desired, this outlet section may be constructed so that it is optional whether drainage is out through a conduit or through another direct drainage opening normally closed by a closure plug or cap.
  • Apparatus for introducing liquid anesthetic into a liquid receiving body of anesthetic apparatus comprising a unit mounted at a selected height on a sidewall of said body, a connection passageway allowing flow of liquid from said unit to said body and flow of air from said body to said unit, an inlet opening in said unit above said connection passageway, said inlet opening being of a sele cted shape and size, separate air and liquid passagesbetwen said connection passageway and the lower side of said inlet opening, a separable connection member complementary to said inlet opening, interference means for ensuring that only a connection member of predetermined form can enter said inlet opening, means securing said connection member in said inlet opening, a flexible conduit carrying said connection member at a first end thereof, said conduit comprising an air flow passage and a liquid flow passage, said connection member when secured in said inlet opening connecting said air and liquid flow passages of said conduit respectively with said air and liquid passages between said connection passageway and said inlet opening, a screw-on cap at a
  • connection member in said inlet opening is a screw screwable into engagement with said connection member.
  • conduit comprises a flexibleouter tube constituting said liquid flow passage and a flexible inner tube lying within said outer tube and constituting said air flow passage, and retaining means are included in said screw-on cap for retaining the end of said inner tube at an angle to the axis of said screw-on cap.
  • Apparatus for introducing liquid anesthetic into a liquidreceiving body of anesthetic apparatus comprising a unit mounted at a selected height on a sidewall of said body, a first connection passageway allowing flow of liquid from said unit to said body and flow of air from said body to said unit, an inlet opening in said unit above said first connection passageway, said inlet opening being of a selected shape and size, separate air and liquid passages between said first connection passageway and the lower side of said inlet opening, a separable connection member complementary to said inlet opening, interference means for ensuring that only a connection member of predetermined form can enter said inlet opening, means securing said connection member in said inlet opening, a flexible conduit carrying said connection member at a first end thereof, said conduit comprising an air flow passage and a liquid flow passage, said connection member when secured in said inlet opening connecting said air and liquid flow passages of said conduit respectively with said air and liquid passages between said first connection passageway and said inlet opening, a screw-on cap at a
