  • the storage bottle in which the anaesthetic is kept during transport from the point of manufacture to the point of use, is provided with a non-return valve in order that the anaesthetic cannot boil away if the bottle is left open.
  • a non-return valve in order that the anaesthetic cannot boil away if the bottle is left open.
  • the vaporizer is provided with a vessel, to which the anaesthetic is transferred and where the vaporization itself occurs (or the atomization into small fluid droplets) .
  • a vessel to which the anaesthetic is transferred and where the vaporization itself occurs (or the atomization into small fluid droplets) .
  • anaesthetic is transferred to these apparatus, sufficient for several hours' use. After use the anaesthetic has to be returned to the storage container. This handling of the anaesthetic gives rise to large losses to the surroundings.
  • the patent EP-B1-231513 describes a vaporizer with a removable container for anaesthetic.
  • This container can be the storage vessel, in which the anaesthetic is trans ⁇ ported, or a separate container, to which the anaesthetic is conveyed. Since the anaesthetic is only in a relatively short tube which leads to a vaporizer, in principal no loss of the anaesthetic occurs upon changing the anaesthetic.
  • a process for filling an anaesthesia apparatus with anaesthetic is disclosed in the aforementioned EP-B1-448 954.
  • a transfer device is used consisting of two link arms joined to each other, said link arms being rotatable relative to each other and comprising a valve.
  • the valve is closed and when the link arms are positioned at 90° relative to each other, the valve is open and transfer to and from the anaesthesia apparatus occurs.
  • This refilling device is well suited for earlier-known anaes ⁇ thetics but cannot be used without modification for desflurane, due to the one-way valve in its transport bottle.
  • the object of the present invention is to provide a transfer device, with which anaesthetic present in a transport bottle with a one-way valve can be transferred to a container in an anaesthesia apparatus.
  • Fig. 1 is an exploded view, in cross-section, of a transfer device according to the invention.
  • Fig. 2 is a cross-sectional view taken along the line II-II in fig. 1.
  • Fig. 3 is a cross-sectional view taken along the line III-III in fig. 1.
  • Fig. 4 is a perspective view of an opening element in the transfer device according to fig. 1.
  • Fig. 5 is a cross-sectional view similar to fig. 1 and showing a first position during the filling operation.
  • Fig. 6 is a cross-sectional view similar to fig. 5 and showing a second position during the filling operation.
  • Fig. 7 is a cross-sectional view similar to fig. 5 and showing a third position during the filling operation.
  • the present invention is described below in connec- tion with an anaesthesia apparatus according to EP-B1-231 513 with a separate container, to which anaesthetic is transferred and which is then attached to the anaesthesia apparatus.
  • a container 1 is shown at the bottom in fig. 1.
  • the container is manufactured of dark-coloured glass and has a connection cap 2 at its upper end.
  • the connection cap 2 has two openings 3, 4 intended for connection to the anaesthesia apparatus.
  • the upper opening 3 is connected to a tube 5 which extends down into the container 1, practically speaking to the bottom thereof. Air is supplied via the lower opening 4, whereby anaesthetic present in the container 1 is pressed out through the tube 5 and the opening 3 for vaporization in the anaesthesia apparatus.
  • Fig. 1 also shows a storage bottle 6 for a volatile anaesthetic such as desflurane.
  • the container 6 is provided at its orifice with a separate connection device 7.
  • the connection device comprises a one-way valve 8 with a spring 9 which presses a rubber membrane 10 against a valve seat 11.
  • the one-way valve also has an actuator member 12 which runs in a hole 13 in the connection device.
  • connection device consists of a cylinder 7 having a substantially planar outer surface 14 ending with a shoulder 15.
  • the outer surface has, just above its lower end 19 as viewed according to fig. 1, an O-ring 16 in order to provide a seal.
  • the inner surface 13 of the connection cylinder 7 is provided with an inner thread 17 of specific type for the anaesthetic in question, a so-called desflur- ane-thread.
  • the one-way valve is further provided with holding legs 18 for guiding and holding in place the spring 9.
  • the function of the one-way valve is very simply that the spring 9 holds the rubber membrane 10 in contact with the valve seat 11 in the normal case.
  • the one-way valve opens and the contents in the bottle can pass out through the cylinder 13 and past the actuator member 12 due to its cross-section which is shown in more detail in fig. 2.
  • an adapter 20 is provided in accordance with the invention (see fig. 1) .
  • the adapter 20 is fixed to the cap 2 by means of adhesive, ultrasound welding, screw connection or in any other suitable way.
  • the adapter 20 is formed by an essentially cylindri- cal housing 21 with a first bore 22 from one side and a second bore 23 from the other side.
  • a web 24 is positioned between the bores 22 and 23.
  • the web is provided with a plurality of continuous holes as shown in the cross-section according to fig. 3.
  • a first central hole 25 is provided with threads.
  • three small holes 26 which form guides for pins of a one-way valve, as will be described in more detail below.
  • medium-sized holes 27 through which anaesthetic can pass from the bore 22 to the bore 23 and vice versa.
  • the adapter is also provided with a one-way valve
  • a plate 29 consisting of a plate 29, on which a rubber membrane 30 is positioned for contact with a valve seat 31 which consists of the lower surface of the web 24 in fig. 1.
  • a spring 32 which presses the rubber membrane 30 against the valve seat 31.
  • the plate 29 is provided with three pins 33 which extend from the plate 29 upwardly through the hole 26 in the web 24 as is clearly shown in fig. 1.
  • the adapter 20 is further provided with an opening element 40 which is shown in more detail in fig. 4.
  • the opening element 40 is positioned in the central hole 25.
  • the opening element is thus provided with a downwardly extending threaded pin 41 which is positioned in the hole 25.
  • the opening element 40 is substantially cylindrical and is provided with an outer thread 42 of specific type for the anaesthetic in question, for cooperation with the desflurane thread 17 in the connection cylinder 7 of the storage bottle 6.
  • the opening element 40 is further provided with a projecting pin 43 at its upper end, the function of which will be described in more detail below.
  • the opening element 40 is additionally provided with a continuous bore 44 which ends in several radial holes 45 so that a passage is formed through the opening element 40.
  • the opening element 40 is positioned centrally in the upper bore 22 of the adapter 20.
  • Fig. 5 shows the storage bottle 6 brought into engagement with the adapter 20.
  • the upper bore 22 of the adapter 20 has a diameter such that the connection cylinder 7 of the storage bottle fits into the bore 22 and so that the O-ring 16 seals against the inner surface of the bore 22.
  • the storage bottle 6 is then rotated relative to the adapter 20, whereby the thread 17 in the connection cylinder 7 cooperates with the thread 42 of the opening element 40.
  • This cooperation only functions if the adapter 20 is adapted to the storage bottle 6 so that the wrong anaesthetic cannot be transferred via the adapter by mistake.
  • the spring 32 of the one-way valve 28 is suitably weaker than the spring 9 in the one-way valve 8.
  • the connection cylinder 7 has come so low down in the bore 22 that the lower surface 19 of the connection cylinder 7 has reached the pins 33 of the one ⁇ way valve 28.
  • the pins 33 are positioned in a circle with such a diameter that cooperation occurs with the lower actuation surface 19 of the connection cylinder 7, seen as in fig. 6.
  • Continued screwing-down of the storage bottle 6 according to fig. 6 causes the one-way valve 28 to be opened by a cooperation between the pins 33 and the actuation surface 19.
  • the one-way valve 28 is thus opened first.
  • the one-way valve 28 Upon continued screwing-down of the storage bottle 6 into the adapter 20 (see fig. 7) the one-way valve 28 is opened completely. At the same time the projecting pin 43 of the opening element 40 cooperates with the actuator member 12 of the one-way valve 8 in the storage bottle 6 so that the one-way valve 8 " will also open, however only after opening of the one-way valve 28. This position is shown in fig. 7 and filling of the contents in the storage bottle 6 to a container 1 positioned below the adapter 20 occurs (see fig. 1) .
  • the anaesthetic can pass the actuator member 12 due to its cross-section, as is clear from fig. 2.
  • the anaes ⁇ thetic can additionally pass the opening element 40 since the outer thread 42 is located on four fingers 46 (see fig. 4) which leave passages between them for the anaesthetic.
  • the anaesthetic also passes through the holes 27 in the web 24 of the adapter 20.
  • the filling sequence ends when the container 1 has been filled to the desired amount by screwing-back the storage container 6 so that the one-way valve 8 closes.
