Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35
U.S.C. .sctn.119 of German Patent Application DE 10 2010 035 993.9
filed Sep. 1, 2010, the entire contents of which are incorporated
herein by reference.
FIELD OF THE INVENTION
[0002] The present invention pertains to a filling system for an
anesthetic dispenser.
BACKGROUND OF THE INVENTION
[0003] A filling system for an anesthetic dispenser has become
known from DE 10 2004 063 883 B3. To be able to fill anesthetic
into an anesthetic evaporator, a bottle adapter is needed, which
makes the connection between the reservoir for liquid anesthetic
and the filling device at the anesthetic evaporator. At the
bottle-side end of the bottle adapter, a threaded sleeve is
provided, which has two grooves for mounting an index collar
attached to the neck of the reservoir. The index collar is coded
anesthetic-specific, so that only the bottle adapter fitting the
reservoir can be screwed onto the bottle thread.
[0004] An anesthetic-specific coding in the form of an outer
polygonal course, which meshes with a corresponding inner polygonal
course at the filling connection piece of the filling device, is
likewise provided at the adapter neck of the bottle adapter.
[0005] The outlet connection piece of the bottle adapter is closed
by means of a spring-loaded adapter valve, so that no anesthetic
can leak into the environment. A corresponding fill valve is
provided at the filling device. On the inner wall of the filling
connection piece are attached inwardly directed rods, which mesh
with corresponding slots at the outlet connection piece of the
bottle adapter and actuate the adapter valve upon pressing the
reservoir. The interplay between the bottle adapter and the filling
device is designed such that first the fill valve at the filling
device opens and then the adapter valve at the bottle adapter
opens. Liquid anesthetic can then flow from the reservoir into the
tank of the anesthetic evaporator. Reference is expressly made to
the entire disclosure content of DE 10 2004 063 883 B3, which is
part of this patent application (corresponding U.S. Pat. No.
7,287,561 is hereby incorporated by reference in its entirety).
SUMMARY OF THE INVENTION
[0006] A basic object of the present invention is to provide a
filling system for an anesthetic dispenser with an additional
coding possibility.
[0007] According to the invention, a filling system is provided for
an anesthetic dispenser. The filling system comprises an anesthetic
evaporator, a bottle adapter having an adapter neck and an outlet
connection piece comprising a slot running in the radial direction
and a central opening connected to the slot. A filling device is
provided at the anesthetic evaporator with a filling connection
piece for mounting the adapter neck. A rod structure is fastened to
the filling connection piece. The rod structure includes a rod
extending radially from a center and meshing with the central
opening.
[0008] The rod structure may comprises a spoked wheel configuration
including the rod and a central flange. The slots may comprise a
slot structure with a spoked wheel configuration at the outlet
connection piece of the bottle adapter. The flange may be designed
corresponding to the central opening. The central opening may
comprise an extension of the slot.
[0009] The spoked wheel configuration of the rod structure may
comprise the rod and additional rods and the flange as a central
punctiform portion or a virtual connection point, at which the rods
converge in a center of the filling connection piece.
[0010] Provisions are made according to the present invention to
provide a central opening, on the front side of the outlet
connection piece of the bottle adapter, which is connected to the
lateral slots. On the inner wall of the filling connection piece
are fastened rods, pointing radially inwards, which preferably
protrude at right angles from the inner wall and whose length is
dimensioned, such that they mesh both with the slots and with the
opening. Instead of the preferred plurality of rods, at least one
rod is present. With a rod length designed in this way, bottle
adapters, which do not have a central opening on the front side of
the bottle adapter, can no longer be inserted into the filling
device. If, by contrast, the rod length is dimensioned such that
the rods lie exclusively in the lateral slots, bottle adapters both
with front-side and without front-side opening can be used. It is
especially advantageous that the coding provided according to the
present invention is downwards-compatible with the solution known
from DE 10 2004 063 883 B3, such that filling devices and bottle
adapters that are present can continue to be used. As alternatives
to a central opening, the slots may also be continued or extended
towards the center, or widen towards the center. These and equally
acting solutions are also expressly intended to be covered by
patent protection.
[0011] It is especially advantageous to design the rod as a spoked
wheel with a central flange and to design the slots at the outlet
connection piece of the bottle adapter and front-side opening
corresponding to the spoked wheel and to the flange. The spoked
wheel consists of individual rods, which are directed towards the
center of the filling connection piece and are connected to one
another in the center via the flange. Additional codings can be
created via the diameter of the flange and the inside diameter of
the opening. The flange may either have a circular design or it is
only a connection point, which connects the spokes to one another.
As an alternative, the flange may be a virtual connection point, at
which the spokes converge in the center.
[0012] It also lies within the framework of the present invention
that the bottle adapter does not have a threaded sleeve, but rather
is rigidly connected to the reservoir for liquid anesthetic or is
directly flanged to the reservoir.
[0013] An exemplary embodiment of the present invention is shown in
the drawings and explained in detail below. The various features of
novelty which characterize the invention are pointed out with
particularity in the claims annexed to and forming a part of this
disclosure. For a better understanding of the invention, its
operating advantages and specific objects attained by its uses,
reference is made to the accompanying drawings and descriptive
matter in which preferred embodiments of the invention are
illustrated.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] In the drawings:
[0015] FIG. 1 is a perspective view showing an anesthetic dispenser
with a filling device for anesthetic according to the invention,
and showing a bottle adapter according to the invention;
[0016] FIG. 2 is a perspective view of a bottle adapter according
to the state of the art;
[0017] FIG. 3 is a perspective view showing a bottle adapter
according to the present invention; and
[0018] FIG. 4 is a top view showing a filling device according to
the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Referring to the drawings in particular, FIG. 1 shows as an
example an anesthetic dispenser 21 with a filling device 20 for
anesthetic. A reservoir 30 for liquid anesthetic is provided with a
bottle adapter 1, which has an adapter neck 5. For the filling
process the adapter neck 5 is inserted into the filling device 20
and the reservoir 30 is pressed in the direction of the filling
device 20.
[0020] FIG. 2 shows a perspective view of a bottle adapter 1
according to the state of the art, as disclosed in DE 10 2004 063
883 B3. The bottle adapter 1 has a threaded sleeve 2 on its bottom
side for screwing onto the reservoir 30 (FIG. 1). The reservoir 30
has an anesthetic-specific index collar (not shown in detail),
which is inserted into mounting grooves 3 of the threaded sleeve 2.
Thus, only one bottle adapter 1 belonging to the anesthetic can be
screwed onto the reservoir 30. The screwing motion is hereby
facilitated by means of recessed grips 4 above the threaded sleeve
2. An adapter neck 5 with an O-ring 6 is located at the upper end
of the bottle adapter 1. The upper end of the bottle adapter 1 has
an outer polygonal course 7 for anesthetic-specific coding as well
as an outlet connection piece 8 with radially running slots 9. The
connection piece top side 10 is designed as a star-shaped body
11.
[0021] FIG. 3 illustrates a bottle adapter 100 according to the
present invention. Identical components are provided with identical
reference numbers of FIG. 2. The bottle adapter 100 has an outlet
connection piece 80 with radially running slots 90. A connection
piece top side 110 includes a shaped body 111. The fact that the
shaped body 111 has a central opening 29 in the area of the
connection piece surface 110 is different from the bottle adapter 1
according to FIG. 2.
[0022] FIG. 4 illustrates the filling device 20 in detailed
sections. The filling device 20 has a filling connection piece 22
with a cylindrical sealing surface 23 and a lead-in bevel 24 for
the O-ring of the bottle adapter 1, 100. With the bottle adapter 1,
100 inserted, the O-ring 6 lies against the sealing surface 23 of
the filling connection piece 22. In the filling connection piece 22
is arranged an inner polygonal course 27, which is designed
corresponding to the outer polygonal course 7 of the bottle adapter
1, 100. On the inner wall of the filling connection piece 22 are
fastened radially inwards directed rods 26, which are designed as a
spoked wheel 25 with a flange 28 mounted in the center. The rods 26
mesh with the slots 9 of the bottle adapter 100 according to the
present invention and the flange 28 lies in the area of the opening
29 and is designed corresponding to the opening 29 in terms of
diameter. When the reservoir 30 is pressed against the filling
device 20, a fill valve (not shown in detail) within the filling
device is opened through the connection piece top side and the rods
26 bring about that an adapter valve (not shown in detail) in the
bottle adapter 100 is opened, so that anesthetic can flow from the
reservoir 30 into the anesthetic dispenser 21. Upon completion of
the filling process, first the adapter valve closes, so that any
residual amounts of anesthetic within the filling connection piece
22 can flow out into the tank of the anesthetic dispenser 21. Then
the fill valve is closed and the bottle adapter 100 can be removed
from the filling connection piece 22.
[0023] By contrast, the bottle adapter 1 shown in FIG. 2 cannot be
used in the filling device 20 according to FIG. 4, since the spoked
wheel 25 lies with the flange 28 on the filling connection piece 22
and the rods 26 cannot be inserted into the slots 11 of the
connection piece top side 10. A filling of the anesthetic dispenser
21 is not possible with the bottle adapter 1, even though it would
be compatible with regard to its anesthetic-specific coding.
[0024] While specific embodiments of the invention have been shown
and described in detail to illustrate the application of the
principles of the invention, it will be understood that the
invention may be embodied otherwise without departing from such
principles.
