CONNECTION ARRANGEMENT FOR CONNECTING AN ANAESTHETIC CONTAINER TO AN ANAESTHETIC VAPORIZER

Abstract

A connection device allows connection of an anesthetic container (400) to an anesthetic vaporizer (300) in a fluid-tight manner. A port section (1000) of the anesthetic vaporizer can be detachably connected to an adapter (1100) of the port section. With the adapter connected to the port section, a vaporizer-side channel section and a container-side channel section together form a continuous channel for anesthetic. The area of the surface of the port section that points towards the adapter is formed by a vaporizer-side contact profile (K.1, K.8), and the area of the surface of the adapter that points towards the port section is formed by a container-side contact profile (K.25, 28, 31). One contact profile has a projection (1), and the other contact profile has a corresponding recess (25) that contact with one another without an intermediate space. The projection positive-lockingly meshes with the recess.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0074] Referring to the drawings, the connection device according to the exemplary embodiment comprises a port section 1000, which is inserted into an anesthetic vaporizer 300, and an adapter 1100, which is inserted into an anesthetic container 400. The port section 1000 according to the exemplary embodiment comprises an inner vaporizer-side component 100 and an outer vaporizer-side component 101. FIG. 1 through FIG. 5 show a first embodiment of the port section 1000 of the anesthetic vaporizer 300. FIG. 1 and FIG. 2 show the inner vaporizer-side component 100 and the outer vaporizer-side component 101, respectively, in a cross-sectional view through the central axis of the rotationally symmetrical port section 1000. The outer vaporizer-side component 101 is indicated by dotted lines in FIG. 1. The inner vaporizer-side component 100 is indicated by broken lines in FIG. 2. FIG. 3 and FIG. 4 show the port section 1000 in a viewing direction from the top and parallel to the central axis of the components 100 and 101, the inner vaporizer-side component 100 being omitted in FIG. 4. FIG. 5 shows the port section 1000 in a viewing direction from the bottom, which is opposite to the viewing direction of FIG. 3 and FIG. 4.

[0075] FIG. 6 and FIG. 7 show in a cross-sectional view a second embodiment of the port section 1000. The inner vaporizer-side component 100 is shown in FIG. 6, and the entire port section 1000 of the second embodiment is shown in FIG. 7. The inner vaporizer-side component 100 comprises in both embodiments (in a sequence from top to bottom) [0076] a head 33 with a truncated cone 1 and with an adjoining washer 2, wherein the truncated cone 1 is permanently connected to the washer 2, [0077] a circumferential sealing ring 4, which is mounted at the washer 2, [0078] a neck 3, which is preferably hollow on the inside, [0079] a washer 5 around the neck 3, which washer 5 adjoins the sealing ring 4, [0080] a collar 12, which is permanently connected to the neck 3 and receives the neck 3, [0081] an inner hollow tube 7, which is permanently connected to the collar 12, [0082] a sealing washer 18 at the outer wall of the tube 7, [0083] optionally a plurality of sliding rings 38 at the outer wall of the tube 7 (cf. FIG. 7), and [0084] a projecting washer 15 at the foot of the component 100, which is permanently connected to the tube 7.

[0085] The projecting washer 15 comprises a circumferential groove, in which a sealing ring 16 is received. All these elements preferably have a rotationally symmetrical configuration and are arranged coaxially to a central axis of the inner vaporizer-side component 100.

[0086] The mushroom-shaped head 33 has a maximum external diameter that is greater than that of the neck 3 and than that of the washer 5. In one embodiment, the entire head 33 and optionally additionally the neck 3 are manufactured from one workpiece, for example, by machining.

[0087] In the exemplary embodiment, the sealing ring 4, the sealing ring 16 and the sealing washer 18 are manufactured from an elastic material. All other elements of the inner vaporizer-side component 100 are manufactured from a solid material, preferably from a metal.

[0088] The outer vaporizer-side component 101 comprises (in a sequence from top to bottom) an adjusting device 8 in the form of a sleeve, [0089] a circumferential projection 13 at the top at the adjusting device 8, the circumferential projection 13 enclosing a flat surface in the form a circular ring, [0090] a collar 9, which is permanently connected to the adjusting device 8, [0091] a larger sleeve 10, which is permanently connected to the collar 9, i.e., the collar 9 connects the adjusting device 8 permanently to the larger sleeve 10, [0092] a smaller sleeve 11, which is permanently connected to the larger sleeve 10, and a circular ring-shaped or beveled transition surface 37 between the sleeves 10 and 11.

[0093] In one embodiment, the adjusting device 8, the larger sleeve 10 and the smaller sleeve 11 are manufactured from a single component, for example, by machining.

[0094] The port section 1000 comprises, furthermore, a vaporizer-side spring element 14 in the form of a helical compression spring, which spring element 14 encloses the smaller sleeve 11, is in contact at the bottom at the transition surface 37 with the larger sleeve 10, is supported at the projecting washer 15 and encloses the sleeve 7. The upper end of the adjusting device 8 forms a flat contact surface K.8 in the form of a circular ring, which is at right angles to the central axis of the outer vaporizer-side component 101. A circular ring-shaped recess 17 is provided in the interior of this contact surface K.8. The neck 3 is passed through this recess 17. The inner wall of the adjusting device 8 comprises a conical segment 19. The outer vaporizer-side component 101 comprises, furthermore, a cylindrical inner wall 35, which is formed by the adjusting device 8 and the two sleeves 10 and 11, cf. FIG. 7. All these elements are preferably arranged rotationally symmetrically and coaxially to a central axis of the outer vaporizer-side component 101. The central axes of both components 100 and 101 are preferably identical. Thanks to the sliding rings 38, the outer vaporizer-side component 101 can rotate relative to the inner vaporizer-side component 100 about the common central axis.

[0095] The entire outer vaporizer-side component 101 is preferably manufactured from a metal.

[0096] The outer vaporizer-side component 101 can be moved linearly along the common central axis relative to the inner vaporizer-side component 100. The vaporizer-side compression spring 14 seeks to move the outer vaporizer-side component 101 away from the washer 15 (the foot). This movement is limited in one embodiment by the circumferential sealing ring 4. In one end position, in which the compression spring 14 has reached the greatest possible length, the contact surface K.8 adjoins this sealing ring 4. The washer 5 meshes with the recess 17 in this position.

[0097] In one embodiment, the movement of the outer vaporizer-side component 101 in the opposite direction is limited by the inner profile 19 of the outer vaporizer-side component 101 touching the outer profile 36 of the inner vaporizer-side component 100. In another embodiment, the smaller sleeve 11 can reach the washer 15 when the compression spring 14 is compressed to a correspondingly great extent, and the washer 15 defines an end position.

[0098] A vaporizer-side channel section K.V, which is shown in FIG. 1 as a dotted area, is formed in the interior of the port section 1000. This vaporizer-side channel section K.V comprises [0099] a segment K.V1, which is arranged in the interior of the adjusting device 8, [0100] a segment K.V2, which is passed through the tube 7, and [0101] a funnel-shaped segment K.V3, which is arranged in the interior of the washer 15, wherein the diameter of this funnel decreases in the direction of the tube 7 and hence of the segment K.V2.

[0102] Segment K.V1 is in fluidic connection with a plurality of openings Ö1 in the contact surface K.B. These openings Ö1 adjoin the neck 3. In the end position shown in FIG. 1, the sealing ring 4 and optionally the washer 2 close these openings Ö1. This position is therefore a blocked end position of the adjusting device 8. The adjusting device 8 is then in contact with the sealing ring 4 in a positive-locking manner. The other end position is reached when the compression spring 14 is compressed to the greatest extent possible and the smaller sleeve 11 is in contact with the washer (the foot) 15 in the configuration shown in FIG. 7. This end position is the released end position of the adjusting device 8. FIG. 1 and FIG. 2 show the adjusting device 8 in the blocked end position. In the released end position, the conical inner wall 19 is flatly in contact with the outer wall 36 of the collar 12 or has—as in the configuration according to FIG. 7—the smallest possible distance to the outer wall 36. The inner wall 19 and the outer wall 36 preferably have the same profile. FIG. 7 shows an intermediate position between the released end position and the blocked end position, in which the vaporizer-side channel section K.V is already opened.

[0103] An intermediate space may develop between the inner wall 19 and the outer wall 36. This intermediate space is, however, permanently in flow connection with the anesthetic tank 304, so that no anesthetic can collect in this intermediate space.

[0104] At the end pointing towards the head 33, the tube 7 of the inner vaporizer-side component 100 is arched towards the neck 3, as a result of which the collar 12 is formed, cf. FIG. 1. A plurality of openings Ö2 are recessed into this arched end 12, cf. FIG. 5. When the adjusting device 8 is in the released end position or in an intermediate position, these openings Ö2 then connect, together with the openings Ö1, the segment K.V2 to the segment K.V1. The openings Ö2 preferably overlap—when viewed in a direction parallel to the central axis of the components 100 and 101, at least partially with the openings Ö1. The funnel-shaped segment K.V3 is permanently in fluidic connection with the segment K.V2.

[0105] The anesthetic vaporizer 300 maintains the anesthetic at a temperature of, e.g., 40° C. An anesthetic tank 304 is often under overpressure. This overpressure propagates into the segments K.V2 and K.V3 and acts in the same direction as the compression spring 14. The compression spring 14 preferably has such a strong spring force, and the openings Ö1, Ö2 are so small that the compression spring 14—supported by the overpressure—pushes the adjusting device 8 rapidly into the blocked end position, so that only a small quantity of anesthetic can escape from the anesthetic vaporizer 300.

[0106] FIG. 8 and FIG. 9 show two slightly different embodiments of the adapter 1100. This adapter 1100 is inserted into the anesthetic container 400, preferably in a detachable manner, and it comprises an inner container-side component 200 and an outer container-side component 201. The inner container-side component 200 is indicated by solid lines in FIG. 8, and the outer container-side component 201 by broken lines. The inner container-side component 200 comprises [0107] a funnel-shaped sleeve 25, [0108] a tube or sleeve 34, which is permanently connected to the funnel-shaped sleeve 25 and has openings in one embodiment (FIG. 9), [0109] a sealing ring 27, which is fastened on the outside to the sleeve 34 (FIG. 9) or to the sleeve 25 (FIG. 8), and [0110] optionally a bracket 32 for the sealing ring 27, which bracket 32 is fastened to the funnel-shaped sleeve 25.

[0111] The outer container-side component 201 comprises (from top to bottom) [0112] a support element 23, which preferably has a dome-shaped or cylindrical configuration, i.e., arches into the anesthetic container 400, and has a plurality of recesses, [0113] a tube 24, which is fastened to the support element 23, [0114] a sealing washer 22, which is received in a corresponding opening in a wall 401 of the anesthetic container 400, [0115] a sealing ring 54, which is received in a groove of the sealing washer 22 (cf. FIG. 16), [0116] a larger sleeve 20, [0117] a circumferential washer 30, which is permanently arranged in the interior of the larger sleeve 20, [0118] a collar 29, which is permanently connected to the larger sleeve 20, [0119] a smaller sleeve 21, which is permanently connected to the collar 29, i.e., the collar 29 connects the two sleeves 20 and 21 permanently to one another, [0120] a circumferential bracket 31, which is permanently connected to the circumferential washer 30, and [0121] a sealing ring 28, which covers the space between the bracket 31 and the inner wall of the smaller sleeve 21 in one embodiment (FIG. 8) and is arranged on the outside at the larger sleeve 20 in another embodiment (FIG. 9).

[0122] Both the outer container-side component 201 and the inner container-side component 201 are preferably manufactured from a plastic, with the exception of the sealing rings 27 and 28. This embodiment reduces the weight. The adapter 1100 made of plastic can be deformed reversibly.

[0123] The adapter 1100 comprises, furthermore, a container-side spring element 26, which is supported at the support element 23, is in contact with the funnel-shaped sleeve 25 and has the shape of a compression spring.

[0124] A container-side channel section K.B, which is shown as a dotted area and comprises the following segments, is formed in the interior of the adapter 1100: [0125] a segment K.B1, which is arranged in the interior of the smaller sleeve 21, [0126] a segment K.B2, which is arranged in the interior of the larger sleeve 20, and [0127] a segment K.B3, which is arranged in the interior of the support element 23.

[0128] The container-side compression spring 26 seeks to push the inner container-side component 200 relative to the outer container-side component 201 into an end position. In this end position, the funnel-shaped sleeve 25 separates the segment K.B1 from the segment K.B2, so that this end position is a blocked end position, in which the bracket 32 and the sealing ring 27 are in contact with the washer 30. When a force is exerted on the funnel-shaped sleeve 25 from below, i.e., through the sleeve 21, the compression spring 26 is compressed, the sleeve 25 is pushed away from the washer 30, and a fluidic connection is generated between the segment K.B1 and K.B2. The segments K.B2 and K.B3 are permanently in fluidic connection with one another.

[0129] The funnel-shaped sleeve 25 is arranged entirely in the interior of the outer container-side component 201 and has a distance to the lower end 40 of this component 201 in the direction of the central axis. As a result, the risk of the sleeve 25 being pressed unintentionally is reduced, the segments K.B1 and K.B2 are connected to one another, and the inner container-side component 200 is moved thereby from the blocked end position in the direction of the released end position and anesthetic can escape.

[0130] In the second embodiment of the adapter 1100, which is shown in FIG. 9, a circumferential contact surface 40 is flatly in contact with the contact surface K.8 of the adjusting device 8. In the first embodiment according to FIG. 8, the contact surface K.8 is, by contrast, in contact at the sealing ring 28 with the sleeve 31. In addition, a circumferential projection 41 is shown. The following is achieved in both embodiments: When the adapter 1100 is placed on the port section 1000, the container-side contact surfaces 28 and 31 or 40 come into contact with the contact surface K.8. In addition, the contact surface K.1 comes into contact with the contact surface K.25.

[0131] When the adapter 1100 is displaced farther towards the foot 15, the container-side contact surface 28 and 31 or 40 pushes the contact surface K.8, which is in contact, and hence the adjusting device 8 against the force of the compression spring 14 out of the blocked end position and into the released end position.

[0132] FIG. 10 through FIG. 13 show in a perspective view an embodiment of how the port section 1000 is assembled. The sealing washer 18 is inserted into a fitting recess in the tube 7. In addition, the sealing ring 16 is placed into the circular groove in the foot 15. FIG. 10 shows the inner vaporizer-side component 100 in a perspective view before the insertion of the sealing washer 18, and FIG. 11 shows it in a perspective view after the insertion. The adjusting device 8 with the circumferential projection 13, the collar 9, the larger sleeve 10 and the smaller sleeve 11 are permanently connected to one another. The container-side compression spring 14 and the connected parts 8, 9, 10, 11 are then pulled from the top over the tube 7, cf. FIG. 11. The sealing washer 4 is pulled from the bottom over the neck 3 and the washer 2, cf. FIG. 12. The parts are assembled, cf. FIG. 13. The two vaporizer-side components 100 and 101 cannot be separated from one another during the regular operation, but are held linearly displaceably in a coaxial position.

[0133] FIG. 14, FIG. 15 and FIG. 16 show in a side view and in a top view how an anesthetic container 400 is attached with an adapter 1100 according to the present invention to an anesthetic vaporizer 300 with a port section 1000 according to the present invention. Both the adapter 1100 and the port section 1000 are preferably rotationally symmetrical about the axis A, so that it is not necessary to bring the adapter 1100 into a defined orientation relative to the port section 1000.

[0134] A schematically shown housing 301, which has a cylindrical tube, which encloses the outer vaporizer-side component 101, belongs to the port section 1000. The outer vaporizer-side component 101 is held in the configuration shown in the housing 301 by means of a plurality of screws 60. These screws comprise preferably spring-mounted spherical pressure pieces, which touch the component 101. It is also possible that the component 101 is held by means of rollers at the screws 60 or without screws by means of spring elements, the spring elements optionally forming a snap holder.

[0135] On attachment, the adapter 1100 is brought first into a coupled state relative to the port section 1000. FIG. 15 shows this coupled state. The larger sleeve 20 of the adapter 1100 now meshes with the intermediate space Zw between the cylindrical inner wall of the housing 301 and the outer contour of the outer vaporizer-side component 101, it encloses the adjusting device 8 of the port section 1000 and lies on the collar 9. The circumferential projection 41 is flatly in contact with the inner wall of the housing 301. In this coupled state, the outer container-side component 201 touches the outer vaporizer-side component 101, while a distance still develops in the direction of displacement between the inner container-side component 200 and the inner vaporizer-side component 100. Contact surfaces of the adapter 1100 and of the port section 1000, which contact surfaces are located opposite each other, touch one another. The sealing ring 28 and the bracket 31 of the outer container-side component 201 are in contact according to the first embodiment according to FIG. 8 with the contact surface K.8 of the outer vaporizer-side component 101. The circumferential projection 13 compresses the sealing ring 28. In the second embodiment according to FIG. 9, the sealing ring 27 is in contact with the contact surface K.B. The contact surface K.25 of the funnel-shaped sleeve 25 and the contact surface K.1 of the truncated cone 1, on the one hand, and the sealing ring 28 in the interior of the sleeve 21 and the contact surface K.8 of the adjusting device 8, on the other hand, touch each other in FIG. 14. The contact between the contact surfaces K.25 and K.1 prevents the adapter 1100 from being moved laterally. The funnel-shaped form of the sleeve 25 and the truncated cone 1 guide together the adapter 1100 into a central position relative to the port section 1000.

[0136] The funnel-shaped sleeve 25 and the adjusting device 8 are still in a blocked state in this coupled state, and anesthetic cannot yet flow. A distance can be seen between the sleeve 15 and the head 33 with the truncated cone 1 in FIG. 15. The two still relaxed compression springs 14 and 26 maintain these blocked states in the coupled state.

[0137] The adapter 1100 is moved now linearly towards the anesthetic vaporizer 300. Depending on the configuration, the sealing ring 28 presses the contact surface K.8 of the adjusting device 8 or the sleeve 20 onto the collar 9. As a result, the adjusting device 8 and hence the entire outer vaporizer-side component 101 are displaced towards the foot 15. The adjusting device 8 is displaced into the released end position and it releases the openings Ö2. The sealing ring 4 does not cover the openings Ö1 any longer, so that the vaporizer-side channel section K.V is opened. In the example according to FIG. 15, the compression spring 14 is first compressed, namely, by the sleeve 20 pressing the sleeve 10 and by the sleeve 10 pushing together the compression spring 14. The vaporizer-side channel section K.V is opened, while the compression spring 26 is still relaxed and a distance is formed between the sleeve 25 and the head 33 and the container-side channel section K.B is therefore still blocked.

[0138] When the adapter 1100 is displaced farther towards the port section 1000 from the position shown in FIG. 15, the sleeve 25 reaches the head 33, the compression spring 26 is pushed together, and the container-side channel section K.B is opened. The container-side channel section K.B. and the vaporizer-side channel section K.V now form together a continuous channel and establish a fluidic connection from the anesthetic container 400 into the anesthetic tank 304 of the anesthetic vaporizer 300. Thanks the force of gravity, the liquid anesthetic flows through this channel obliquely downwards into the anesthetic tank 304. Only liquid anesthetic flows then in the exemplary embodiment through the channel into the anesthetic tank 304 when and as long as a user holds the anesthetic container 400 against the force of the two springs 14 and 26 in the flow state relative to the anesthetic vaporizer 300. It is ensured hereby that a user is always in the vicinity during the flow of anesthetic.

[0139] A single channel is provided in the embodiment shown between the anesthetic container 400 and the anesthetic vaporizer 300. On the one hand, liquid anesthetic flows obliquely downward through this channel. On the other hand, gas containing evaporated anesthetic escapes from the anesthetic tank 304 through the same channel obliquely upwards. The funnel-shaped segment K.V3 in the foot 15 collects and centers rising gas and guides this gas into the segment K.V2. The risk that gas would escape from the anesthetic tank 304 into the environment is reduced thereby. FIG. 17 shows in an overview diagram a bayonet connection between the adapter 1100 and the port section 1000. FIG. 18 shows a detail view of this bayonet connection. A projection 50 at the larger sleeve 10 of the outer vaporizer-side component 101 meshes with a corresponding, obliquely arranged recess 51 at the larger sleeve 20 of the outer container-side component 201. In order to connect the adapter 1100 to the port section 1000, the projection 50 is pushed through a slot 53 in the outer vaporizer-side component 101, and the adapter 1100 is then rotated together with the projection 50 until the projection 50 reaches the end of the recess 51. The adapter 1100 is removed from the port section 1000 again by a reversed movement. In addition, an optional valve 52 is seen in FIG. 17. Gas can escape from the anesthetic tank 301 through this valve 52, while the anesthetic tank 301 is being filled with an anesthetic.

[0140] 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.
