Abstract

The invention concerns a device (V) for mixing and dispensing multicomponent products (I, II) which are located in a chamber (1) from which they can be dispensed by a piston (19) which is displaceable in the direction of a discharge opening (8) by means of a piston-actuating handle (22). The device enables even difficult preparations to be handled reliably and advantageously owing to a mixing element (M) which is movable in the chamber (1), is disposed upstream of the piston (19) and can be moved by the piston-actuating handle (22).

Description

00001 Device for mixing and spreading multi-component

00002 products

00003

The invention relates to a device for

00005 mixing and spreading of multi-component products,

00006 which is arranged in and out of a chamber

00007 a displaceable in the direction of a dispensing opening

00008 bring out the piston by means of a piston actuation handle

00009 bar. 00010

A device of this type is through the

00012 DE-PS 19 39 316 known. After uniting there

00013 reacting two substances for the manufacture

00014 of a ready-to-use dental preparation, the pre

00015 direction in a special vibratory mixing device

00016 clamped. The output of the so homogeneously posed

00017 dental preparation is done in the direction of

00018 dispensing opening displaceable piston of the here in Art

00019 a syringe designed device. From the back of the

00020 piston is accordingly designed as a cross handle

00021 tete, freely accessible piston actuation handle.

00022 One component is liquid. It deals

00023 is phosphoric acid. It's in a breakout ampoule

00024 included. The latter lies in the direction of the

Seen the device in front of the piston. The cam

00026 mer is divided by a perforated partition.

The latter forms the piston-side support of the

00028 glass manufactured crushing ampoule and stretches

00029 above a subsequent one, the second component

00030 containing area. Regarding the second component

00031 is a powdery substance,

00032 for example zinc oxide. Releasing the liquid sub-

00033 punching is done through a willful pressure

00034 by means of the piston. The breaking ampoule is broken

00035 chen. The glass splinters are said to be perforated 00036 of the movable partition are retained.

00037 The corresponding separation is understandable

00038 vague. The chamber is open to the outside and therefore

00039 not finished odor-tight. About the piston

00040 the finished dental preparation finally via the output

00041 opening pushed out and brought to the destination.

For this purpose, the cannula or spout is designed

00043 release opening, for example by pulling

00044 of a plugging or cutting off a closed canister

00045 lens tip or the like. 00046

The object of the invention is to provide a generic

00048 to specify the direction in which the creation in particular

00049 also problematic preparations from several components

00050 safe and much easier to use allowed. 00051

00052 This object is achieved by the

00053 ben invention. 00054

00055 subsequent claims give advantageous width

00056 formations of the invention. 00057

According to such an embodiment is a generic

00059 device of increased use and safety value

00060 achieved. No special mixing device is required

00061 more. The whole thing is achieved simply by an internal

00062 movable half of the chamber, upstream of the piston

00063 and movable by means of the piston actuation handle

00064 mixing element. The latter is mechanically revolutionary

00065 through the mix. There is a high grade

00066 homogeneity. That happens along the entire length of the

00067 chamber. No areas remain unturned. The

00068 quality of the preparation is accordingly good. In the

Mixing of the chamber 00069 leaves no smell

Step outside. The piston acts as a side 00071 trap. The thing is sterile. In front-

Directionally advantageous is the measure that

00073 the mixing element as a perforated, linear in the chamber

00074 displaceable disc is designed. Usually one

00075 brings the cross section of the chamber adapted disc

00076 consequently an equal mixing effect, and

00077 completely independent of the location of the device. she

00078 can be turned upside down or horizontally

00079 orders, etc. This is noticeably more effective than

00080 the wandering dune-like displacement of the

00081 substance in a vibrating mixing device. Such a

00082 disk can also be quite thin, so that a

00083 due to limited volume loss of the chamber

00084 is acceptable in view of those achieved in return

00085 intensive mixing effect. A structurally advantageous

00086 adhesive solution then results from the fact that the mixed

00087 element at the free end of one centrally in the longitudinal axis

00088 a cylindrical chamber displaceable rod sits,

00089 which at the end lying outside the chamber

00090 manual operation and in its range

00091 of the chamber carries a threaded spindle which is

00092 ster, but axially movable coupling to the rod.

00093 The mixing stroke can thus be carried out directly and independently of the

00094 piston displacement are carried out. In addition,

00095 change the volume of the chamber so that the piston

00096 practically also the function of an adjustable ceiling

00097 the chamber receives. Since the thread of the threaded spindle in

00098 self-locking area is about emerging

00099 internal pressure in the chamber has no influence with regard to

00100 change the position of this blanket, ie piston, 00101. The desired linear actuation of the disc is

00102 achieved in that the clutch by wing of

00103 rod is achieved, which in a longitudinal slot of the

00104 engages threaded spindle. Such rotary drivers

00105 wings can be integrally molded and Connect 00106 to the free end of the rod. By doing so

00107 wings are webs of the mixing element, the mixing element

00108 ment another function. Next is the device

00109 device characterized by a bush-shaped end

00110 cut the lead screw beyond the range of

00111 longitudinal slit for the purpose of mounting the threaded spindle

00112 of the cylindrical rod. The bush-shaped

00113 end portion corresponds approximately to the axial thickness of the

00114 pistons. It is the zone anyway, which is not for the

00115 displaceability of the mixing element is required. in the

00116 area of the socket-shaped end portion is that of

00117 House made of tubular, previously slotted

00118 threaded spindle stably held together. The through the

00119 threaded spindle drive resulting displacement of

00120 piston is practically slip-free because the piston passes through

00121 its circumference, in particular its piston ring, friction

00122 arranged non-rotatably in the cylindrical chamber

00123 is net. A measure that promotes mixing depending on the substance

00124 then exists through a suction pipe connection piece

00125 in the end region of the chamber on the handle side, namely in

00126 Direction of the dispensing opening in front of the withdrawn one

00127 piston lying. A safe-to-use spindle guide

00128 results from the fact that the free, slotted end

00129 the threaded spindle in a recess of the output

00130 comfortably intersecting web is stored. To the

00131 device in a convenient handling position

To be able to press 00132, it is further proposed that

00133 a closure cap closing the dispensing opening

00134 is designed as a base plate. The invention strikes

00135 further training of even independent

00136 meaning with regard to composing the components

00137 ten vor: This results from a

00138 housing for housing the second component, the

00139 housing interior can be connected to the interior

00140 clears the chamber containing the mixing element. In the 00141 according to the present summary of

00142 device for a combination device proves

00143 an embodiment in that the

00144 connection by moving the housing relative to

00145 chamber can be achieved. In concrete terms, it looks like

00146 that the chamber has a bearing socket for a bearing bush

00147 of the housing and the connection by cover

00148 same position of free spaces of both parts to each other

00149 is achieved. That creates a kind of lock. Through the

00150 corresponding rotation pointer-like assignment of the housing

00151 this can also be used as an operating handle

00152 Establishing said connection. It is

00153 advantageous that the housing as a lid lockable

00154 recording for a crushing ring ampoule is designed. WEI

00155 ter is proposed that the bearing neck of the chamber

00156 in the end region of the discharge opening facing

00157 chamber lies. For the functional assignment of the

00158 for example containing the liquid component

00159 crushing ring ampoule is further proposed that the

00160 bearing socket an elastic receptacle for the ampoule

00161 spit has the crushing ring ampoule and the housing

00162 leaves a space for axial retraction

00163 Cancellation of the ampoule skewer by moving the

00164 housing relative to the bearing neck of the chamber. With simple

00165 Chen means is the elastic absorption of one

00166 inside the contour of the spout formed on the ampoule spit

00167 formed, which is in a transverse blind hole

00168 of the bearing neck extends. The cross-joint

00169 ampoule skewer is securely in the elastic holder

00170 held while the ampoule body in a

00171 release of the liquid component bringing fall position

00172 is pivoted. The bearing bush is axially from the

00173 stub removable, which is because cleaning or sterile

00174 accessible, multiple use of the devices

00175 tion opened. Finally, it is suggested that the 00176 relocation from the housing to the bearing socket is realized as a rotary movement and with limited stops. Finally 00178 the invention proposes that the housing 00179 in the insertion position for the crushing ring ampoule is parallel to the longitudinal direction of the chamber. This loading position 00181 also results from the footplate suggesting the standing position, so that incorrect operation is practically impossible. Finally, a perfect 00184 usage function is achieved by a locking ring closing the longitudinal slot 00185 against the piston. The 00186 mix cannot step behind the pistons. 00187 00188 The subject matter of the invention is explained in more detail below with reference to 00189 of an exemplary embodiment illustrated in the drawing. It shows: 00191 00192 FIG. 1 the device containing the components in 00193 vertical section, in the standing position, 00194 00195 FIG. 2 the device in side view, namely 00196 against the side having the housing, 00198 00199 FIG. 3 one the representation corresponding to FIG. 2, 00200, however, brought into a position 00201 turned through 180 °, with the joint point shown 00202 between the chamber and the housing, 00203 00204, FIG. 4 shows a same representation with 00205 pivoting of the housing relative to the chamber, 00206 under Breaking the crushing ring ampoule, 00207 00208. FIG. 5 shows an illustration corresponding to FIG 00210 housing with clarification of the components 00211 combination, 00212 00213 Fig. 6 the device in a perspective view 00214 with the housing removed to clarify the articulation point 00215, 00216 00217 Fig. 7 the section along line VII-VII in Figure 1, 00218 00219 Fig. 8 is a vertical section through the chamber under 00220 clarifying the mixing process and 00221 00222 Fig. 9 is a same section when discharging the 00223 homogeneously mixed multi-component product 00224 by means of a spindle drive via a piston. 00225 00226 The device V shown for mixing and dispensing multi-component products comprises a chamber 1 00228 and a housing 2. 00229 00230 The chamber 1 accommodates a first component I. 00231 is powder. 00232 00233 The housing 2 is assigned a second component II. 00234 the latter is liquid in nature and is located in a 00235 fragile glass ampoule, referred to throughout as 00236 crushing ring ampoule 3. Its ampoule spike 4 breaks without 00237 prior filing of its wasp waist-like neck 5 between ampoule body and head. 00239 The corresponding procedure is explained below 00240. 00241 00242 The components 1.11 00243 introduced into the device V require different precautions in certain cases. For example, for the production of bone cells 00245 ment, the relevant powder is first gamma-treated

00246 shines. This can only be done in the absence of the second

00247 nente II happen. Regarding these second components

00248 ten II is, for example, methyl meta-

00249 chrylate monomer. The latter substance is problematic

00250 table for toxic evaporation. The

00251 device V is designed accordingly, i.e. the

00252 preparation takes place in a hermetically sealed

00253 a sterile zone. The correspondingly sealing

00254 conclusion is not specifically described by

00255 nete sealing rings - and bushings realized (see drawing

00256 solution). 00257

00258 The chamber offering the larger usable volume

00259 1 represents the mixing zone and at the same time the application

00260 advises. It (1) is in the form of an elongated sleeve 6

00261 designs. At least its inner wall 7 is cylindrical. 00262

00263 The sleeve 6 forms one end of an output opening 8. Die

00264 is centrally located. It closes via a perpendicular to the

00265 longitudinal longitudinal axis x-x of the chamber standing shoulder 9

00266 to a stub 10 projecting outwards. The

00267 carries external thread 11 for engagement in a corresponding

00268 of the internal thread of a foot plate 12 as an adjustment aid

00269 device V or chamber 1 (see standing position

00270 Figure 1). 00271

00272 The base plate 12 is also a closure cap.

00273 siert. For this purpose, it forms a plug 13, which

00274 sealingly enters the discharge opening 8. The central

00275 lying plug 13 is the base plate 12 in one piece

00276 molded. Sits to enlarge the footprint

00277 the base plate 12 on the installation side in a transverse

00278 cut the chamber edge 1 clearly superior 14th

00279 continued. The rotationally symmetrical protruding setting edge 14 00280 has a knurling 15 peripherally to increase the grip

00281 ability. 00282

00283 The other end of chamber 1 is also tight

00284 lockable with a closure cap 16. It functions

00285 as head plate. There is also a screw

00286 conclusion based; the external thread of this cap

00287 16 means 17. The matching counter thread is in the

00288 there end region of the inner wall 7 of the chamber-forming

00289 the sleeve 6. The actual head plate forming

00290 batch of the cap 16 goes into a turning handle

00291 above, also with to increase grip

00292 see knurling 18. 00293

00294 The chamber 1 contains a longitudinally displaceable therein

00295 arranged piston 19. About the latter, the

00296 mixed multi-component product I / II through the output

00297 Push opening 8 through. The piston displacement

00298 is done via a threaded bearing on both ends

00299 spindle 20. A rotary drive of the piston itself can

00300 switched off via longitudinal guides on the inner wall 7

00301. Such means are in the embodiment

00302 not shown. It was found that the piston 20th

00303 sufficiently frictionally and thus non-rotatably in the

00304 cylindrical chamber 1 is held. Is favored

00305 this rotation lock still through one of the jacket wall of the

00306 piston 19 associated piston ring 21

00307 cross section of chamber 1 and piston 19 it is self-00308 speaking.

00309

00310 The displacement of the piston 19 takes place via one of

00311 accessible piston actuation handle 22,

00312 via which the threaded spindle 20 is set in rotation

00313 will. This is done indirectly via a central one

00314 rod 23, using a means of 00315 piston actuating handle 22 movable mixing element

00316 M. 00317

00318 The mixing element M sits at the end of the chamber

00319 rod 23 and is in the form of a linear in the chamber l

00320 displaceable disc 24 designed. The relatively thin

00321 disc 24 lying transversely to the longitudinal central axis x-x

00322 over the entire free inner length of chamber 1

00323 move, i.e. starting from the inside of the ring

00324 shoulder 9 to immediately in front of the printing surface 25 of the

00325 piston 19, which in the basic position is limited to the end

00326 inside of the top plate i.e. Sealing cap 16

00327 lies, that is, against the inside of the cap 16.

00328 The direction of displacement of the mixing element M is through

00329 Double arrow y marked. 00330

00331 The rod 23 is in the hollow threaded spindle 20

00332 leads. The edge of the so over the centrally guided rod

00333 23 also guided on the threaded spindle 20

00334 th disc 24 ends in a radial, a small

00335 gap leaving gap in front of the inner wall 7 of the

00336 Chamber 1. The mix can pass here. The disc

00337 24, as can be seen from FIG. 7, is also rich

00338 broken. The breakthrough is formed according to

00339 archer 26 distributed at equal angles.

00340 the latter form a rich lattice structure, so that a

00341 high-grade, uniform mixing effect

00342 reason for the appropriate crackdown. The as a

00343 tric circular arches realized archer

00344 26 are arranged in two or more concentric rows

00345 net, equally angularly spaced and leave radial bridging

00346 ken 27 between continuous rings 28. Die

00347 radial bridges 27 extend on the angle bisector

00348 ends of the neighboring archer 26. There are

00349 because four archers realized in a row of rings. 00350 From the inner ring 28 is the connection of the disc

00351 24 toward the inner end of the rod 23

00352 men. The disc 24 is in a rotationally fixed

00353 connection. The same applies to the area there

00354 non-rotatable connection to the threaded spindle 20 given.

00355 The threaded spindle 20 is here, as already indicated

00356 tet, at the same time in axially movable coupling to the rod

00357 23. 00358

00359 The clutch is reached by wing 29. Latter

00360 go inside from the inner ring 28 of the disk 24

00361. Here are only two arranged in the diametral

00362 wing 29 realized. The desired clutch can be

00363 practically realized with only one wing 29.

00364 In principle, more than two wings 29 are also possible.

00365 bar. 00366

00367 The wings 29 pass through a longitudinal slot 30 of the

00368 threaded spindle 20. The wings 29 also form webs here

00369 of the mixing element M. According to the longitudinal

00370 slot 30 in the longitudinal central axis x-x of the cylinder

00371 drische Chamber 1 displacement of the rod

00372 23 for the described mixing process without hindrance

00373 given. 00374

00375 The end of the threaded spindle 20 on the head plate side

00376 forms a socket-shaped end section 31 of the same.

00377 So there remains a closed cross section

00378 of the threaded spindle 20 received. It is a matter of

00379 an end section which in the basic position of the piston 19th

00380 mainly a collar 32 directed inwards

00381 of the piston 19 penetrates. The collar 32 and, if applicable, the bottom of the

00383 pot-shaped pistons 19 contain that with the thread

00384 33 of the threaded spindle 20 cooperating internal thread 00385 of the piston 19. In the case of a

00386 ter slot seal is the bottom threaded

00387 end not included. 00388

00389 The thread-free, stepped end of the threaded spindle 20

00390 enters a bearing 34 there. The bearing

00391 34 is on one of the top plate of the cap

00392 16 outgoing connection piece 35 directed towards the chamber

00393 formed. The latter has such an axial length

00394 that it also has the collar 32 pointing in the opposite direction

00395 of the piston 19 comprises radially supporting and so the

00396 piston in its initial movement also leads peripherally.

00397 There is an extremely stable storage of the concentric

00398 interlocking or nested parts. 00399

00400 Before the front end of the stepped end of the thread spin

00401 dei 20 is a sealing element 36 which

00402 sealing the jacket wall of the cylindrical rod 23

00403 encloses. For the passage of the rod 23 is

00404 in the head plate of the cap 16 a central

00405 bore 36.00406

00407 The actuating handle 22 is designed as a crank.

00408 your cranks perpendicular to the longitudinal central axis x-x

00409 arm 38 sits in the opposite direction to an axle bearing

00410 continue rotary knob 39 in the appropriate arm length, see above

00411 that a cross handle is created, the higher actuation

00412 transferable, especially when piston

00413 caused application of the multi-component product I / II.

00414 A chamber-side receptacle 40 for the

00415 cantilevered end of rod 23 is of such a length

00416 that there is a sufficient free gripping space between the

00417 chamber 1 and the crank arm 38 remains. 00418 00419 The bearing of the end of the threaded

00420 spindle 20 is similarly solved by also there

00421 thread-free section of the slotted here

00422 end of the thread play 20 in a recess 41

00423 protrudes the cross-section 8 of the crosspiece 8.

00424 Said web 42 ends immediately before the inner end

00425 of the plug 13.

00426 that from the bottom of the cup-shaped web 42 a central one

00427 standing pin 43 goes out, the cross-section adapted in the

00428 central bore 44 of the hollow threaded spindle 20 rotating

00429 is the leader. The recess 41 is also cross-sectional

00430 matched so that a peripheral support

00431 of the threaded spindle forked by the slot 30

00432 20 is reached. Of course, the web 42 is fixed with

00433 of the inner wall of the circumscribing the dispensing opening 8

00434 connected to the nozzle 10, for example via radial

00435 material bridges. Filling the chamber 1 with the

00436 first component I can about one or the other

00437 apparent end of the device V has been made. 00438

00439 The housing 2 accommodating the second component II

00440 is closely adjacent to chamber 1. The housing 2

00441 is of a substantially cylindrical sleeve 45

00442 formed, from the housing interior 46 the

00443 liquid component II is connectable to

00444 interior 47 of the chamber containing the mixing element M.

00445 1. The corresponding connection is only emphasized

00446 possible, specifically by means of a device V

00447 taking movement. Specifically, this happens so that the

00448 unifying path of the two components 1.11 through one

00449 displacement of the housing 2 relative to the chamber 1

00450 is enough. The union of the two components

00451 1.11 happens in terms of fluid flow via a channel,

00452 in particular cross channel K, and mechanically through that

00453 Aborting the ampoule skewer 4 mentioned above 00454, the housing 2 is pivoted. The panning happens

00455 around a bearing socket 48. The latter goes radially

00456 tet, i.e. perpendicular to the longitudinal central axis x-x,

00457 from the jacket wall of chamber 1 and is from one

00458 bearing bush 49 of the housing 2 sealed with a rotary joint

00459 attacked. Bearing socket 48 and the rotary joint forming

00460 inner surface of the bearing bush 49 are corresponding cylindrical

00461 designed drily. 00462

00463 The bearing socket 48 lies in that of the discharge opening 8

00464 facing end area of chamber 1. 00465

00466 The loading end of the housing 2 is in the

00467 Figure 1 apparent basic position the area of

00468 piston actuation handle 22 facing. The housing 2

00469 is in the insertion position for the crushing ring ampoule 3

00470 parallel to the longitudinal direction of chamber 1. These end positions

00471 tion is defined by a first end stop a

00472 kidney. For this purpose, a concentric

00473 supply of the housing 2 lying slot slot 50

00474 starts from the jacket wall of the bearing socket 48 and

00475 receives a stop pin 51. The latter is from

00476 formed a grub screw. The radially penetrates the

00477 wall of the bearing bush 49 and also affects

00478 Figure 2 resulting insertion position with the there

00479 gene end stop a of the bearing socket 48 together. The

00485 as 100 °. From the, apparent from Figures 4 and 5

00486 Chen movement out there is the task of coaxial

00487 of crushing ring ampoule 3 and ampoule skewer 4. 00488 00489 The corresponding coaxiality, however, lies with the loading

00490 of the device V. For this, the

00491 lockable receptacle designed housing 2 opened.

00492 being captive and tightly assigned dec-

00493 kel is denoted by 52. The crushing ring ampoule 3

00494 introduced with the ampoule skewer 4 facing downwards.

00495 The latter comes in in the relevant end position

00496 an elastic receptacle 53. It holds the ampoule stick

00497 in the bearing socket 48 by the root of the arrow

00498 tig-shaped skewer for wasp waist-like neck 5

00499 is undercut behind. The elastic

00500 see picture 53 can be made of a rubber or sponge

00501 gene body in the form of a pot-like spout

00502, which in this position is coaxial to the housing

00503 pocket-side bore 54 is inserted,

00504 here too by the restoring force of the material

00505 self-captivating way. The elastic body tolerates

00506 slightly different tilting of the ampoule body,

00507 so that it does not even with different tolerance pairings

00508 for premature breaking of the ampoule skewer 4

00509 is coming. 00510

00511 The mouth of the spout, which is open on the joint side, forms one

00512 funnel. It has a centering effect. 00513

00514 The breaking occurs only when the housing is swiveled

00515 ses 2 in the direction of the arrow z. For this purpose, the device V

00516 appropriately in the position shown in Figure 3

00517 brought, that is turned by 180 ° compared to Figure 1. In

00518 this position is a flow connection between

00519 the housing interior 46 and the interior 47 of the chamber

00520 1 excluded. A housing-side clearance Fl and

00521 a chamber-side free space F2 are sealed by

00522 conclusion between the jacket wall of the bearing socket 48 and

00523 of the corresponding bearing wall of the bearing bush 49 00524 still closed. The corresponding chick-like

00525 closing point is designated 55. The flow connection

00526 fertilizer is rather only by practically congruent

00527 position of the clearances Fl and F2 of both parts to each other

00528 which achieved (see Figure 5). 00529

00530 Even if the ampoule skewer 4 is broken off does not occur

00546 ampoule 3 an axial evasion clearance within the

00547 housing 2 given. Reference is made to FIG. 3. The

00548 Evasion clearance is labeled A. Its function

00549 results from an excess of space there in the club

00550 with a suspension of the crushing ring ampoule 3 over her

00551 ampoule skewer 4. The bottom 57 of the crushing ring ampoule 3

00552 is at a distance from the corresponding floor

00553 58 of the housing interior 46. Said floor 58 is

00554 formed from the inside of the ceiling of the cover 52.

00555 The latter is over a shoulder 59 after the

00556 outward facing end edge forming the housing 2

00557 the sleeve 45, thus extending the interior 46,

00558 supports. So it is avoided with a high degree of certainty that 00559 glass splinter gets into the substance to be mixed. In the

00560 position shown in Figure 5 rides the fracture

00588 inward fingers 63 the longitudinal slots re-

00589 spotting longitudinal slit 30 completely closing across

00590 seals to the outside. The locking ring 62 is supported

00591 in a matching receptacle 64 at the foot of the federal government 32

00592 on the piston side. The free ends of the fingers 63 follow

00593 the contour of the rod 23. The ring section of the locking 00594 total 62 overflows the thread 33 of the threaded spindle 20

00599 reuse should be sought, so it turns out for

00600 a cleaning the accessibility of the rooms via the

00601 base plate 12, the closure cap 16 and the lid 52

00602 as useful. A supplementary measure in this regard

00603 results from the fact that the bearing bush 49

00610 Mixing can be done in a vacuum situation

00611. For this purpose, the chamber 1 has a lockable

00612 connecting piece 65. The latter extends in

00613 handle-side end portion of chamber 1, namely

00614 before the piston in its end position

00615 19 lying. The corresponding suction line is not
