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).

00003

00004 The present invention relates to an apparatus for

00005 mixing and dispensing multi-component products,

00006 which are arranged in a chamber and from this through

00007 displaceable in a direction of a discharge opening

00008 piston by means of a piston actuating handle ausbring-

are 00009 bar. 00010

00011 A device of this kind is by the

Known 00012 DE-PS 19 39 316th After combining the there

00013 reacting the two substances for the preparation of

00014 a ready dental preparation is pre-

00015 direction in a special swing mixing device

00016 clamped. The output of as homogeneous asked

00017 dental preparation is done on the in the direction

00018 delivery opening movable piston of here in Art

00019 designed a syringe device. From the back of the

00020 piston is accordingly an gestal- as a T-handle

00021 tete, made freely accessible piston actuating handle.

00022 One component is liquid in nature. It deals

00023 is phosphoric acid. Which is in a crushing ampoule

00024 included. The latter is, in the direction of Ausgabeöff-

00025 of the device voltage seen, in front of the piston. the Chamber

00026 mer is divided by a perforated intermediate wall.

00027 latter forms the piston side of the support from

00028 Glass breaking ampoule manufactured and extends

00029 above a subsequent, the second component

00030-containing region. With respect to the second component

00031 is a powdery substance, examples

00032 game as zinc oxide. Releasing the liquid sub-

00033 punch is via a willing emphasized applying pressure

00034 by means of the piston. The crushing ampoule is zerbro-

00035 chen. The pieces of glass are to a perforation of the 00,036 displaced partition be retained, according to.

00037 The corresponding deposition is understandably

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

00039 geruchtsdicht not completed. is the piston

00040, the finished dental preparation finally via the output

expelled 00,041 opening and then moved to the destination.

00042 For this, the cannula or tüllenförmig designed

release 00043 dispensing opening, for example by pulling

00044 a plug or cutting a coated supplied Kanü-

00045 lenspitze or the like. 00046

00047 object of the invention is to provide a generic pre-

00048 indicate direction which in particular the preparation

00049 also problematic preparations of several components

00050 safe and much cheaper handling allowed. 00051

00052 Solved is this object by the angege- in claim 1

00053 ben invention. 00054

00055 This result led claims indicate advantageous Weite-

00056 of the invention formations on. 00057

00058 of such a configuration is a generic

00059 device for use and increased security value

00060 achieved. It requires no special mixing device

00061 more. Achieved is the whole simply by intra-

00062 half of the chamber movable, upstream to the piston

00063 and movable by means of the piston actuating handle

00064 mixing element. The latter engages mechanically revolutionary

00065 through the mix. There is a high grade

00066 homogeneity. This is done on the entire length of the

00067 Chamber. There remain no areas unumgewälzt. The

00068 Quality of the preparation is correspondingly good. In the

00069 Chamber of happening mixing leaves no odor

00070 escape to the outside. The piston acts as there sided 00071 odor trap. They thing is sterile handle. In front-

00072 is directionally advantageous is the measure that

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

00074 movable disk being constructed. A rule

00075 adapted to the cross-section of the chamber brings disk

00076 therefore an equal mixing effect, and

00077 indeed completely independent of position of the device. you

00078 can reasonable upside down or horizontally lying

00079 classified, etc. This can be seen more effective than

00080 the shifting dunes like walking in front of moving the

00081 substance at a swing mixing device. a sol

00082 che disc can also be quite thin, so that a DA

00083 by conditional less loss of volume of the chamber

00084 is acceptable in view of the achieved in return

00085 intensive mixing effect. A structurally advanta-

00086 exemplary solution is then obtained in that the mixing

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

00088 of a cylindrical chamber movable rod sits

00089 on which lying outside the chamber end of the piston

00090 benbetätigungshandhabe and its extension area

00091 of the chamber carries a threaded spindle which in drehfe-

00092-the-art, but axially movable coupling to the rod stands.

00093 The mixing stroke can thus immediately and independently of the

00094 piston displacement are performed. Also can be

00095 to change the volume of the chamber so that the piston

00096 practically the function of a ceiling readjustable

00097 obtains the chamber. Since the thread of the threaded spindle

00098 self-locking range, may be about emerging

00099 internal pressure in the chamber no effect in terms of

00100 a change in position of the ceiling, ie piston off, practice 00,101th The striving for linear actuation of the disc is

00102, achieved that the coupling of the wing by

00103 rod is achieved, the so in a longitudinal slot

00104 threaded spindle engages. Such rotary drivers forming

00105 wing can be integrally molding and 00106 connected to the free end of the rod of the disc. By then the

00107 wings are lands of the mixing element, comes the Mischele-

00108 ment to another function. Next is the Vorrich-

00109 tung characterized by a sleeve-shaped Endab-

00110 of the threaded spindle cut beyond the range of

00111 longitudinal slot for storage of the threaded spindle

00112 of the cylindrically-shaped rod. The bush-shaped

00113 end portion corresponds approximately to the axial thickness of the

00114 piston. It is already the zone, which is not for the

00115 displaceability of the mixing element is required. in the

00116 is the region of the socket-shaped end portion of

00117 home tubular, until then longitudinally slotted

00118 screw stable together. By the

00119 threaded spindle drive state coming displacement of

00120 piston is practically free of slip, because the piston by

00121 its circumference, especially its piston ring friction,

00122 positively non-rotatably in the cylindrical chamber angeord-

net is the 00,123th A mixing-promoting substance, depending on the measure

00124 is then passed through a suction line Ansσhlußstutzen

00125 in the handle-side end region of the chamber, in

00126 towards the discharge opening before the retracted

00127 piston lying. A safe use spindle guide

00128 results from the fact that the free slotted end

00129 of the threaded spindle in a recess of a the expenditure

00130 bequerschnitt intersecting web is supported. To the

00131 handling device in a comfortable standing position

to actuate 00132, it is further proposed that

00133 a discharge port closing cap

00134 is formed as a footplate. The invention proposes

00135 Moreover, a development even of independent

00136 significance in regard to composing the compo-

00137 th before: The results from one of the neighboring chamber

00138 tes housing for receiving the second component, whose

00139 housing interior in connection can be brought to the interior

00140 cavities of the chamber containing the mixing element. In the 00141 accordingly presented here Summary

00142 device to a combination device proves

00143 a configuration of the effect to be useful that the

00144 compound by displacement of the housing relative to the

00145 chamber is achievable. Structural concrete looks like this,

00146 that the chamber has a bearing support for a bearing bushing

00147 of the housing has, and the connection of cover by

00148 same position of open spaces of the two parts to one another

is achieved 00,149th This results in a kind of lock. by

00150 corresponding rotating pointer-like allocation of the housing

00151 this is also usable as an operation handle for

00152 induction of said compound. It is

00153 advantageous that the housing and sealable

00154 recording is designed for a break ring vial. WEI

Ter 00155 it is proposed that the bearing connection of the chamber

00156 in the facing end portion of the dispensing opening

00157 Chamber is. To functionally appropriate allocation of

00158 For example, the liquid component containing

00159 break ring ampoule is further proposed that the

00160 bearing supports a resilient seat for the ampoule

00161 pike of the break ring and the housing has ampoule

00162 leaves a free space according to axially receding

00163 cancel the ampoule spear by moving the

00164 housing relative to the bearing supports of the chamber. with simple

00165 chen means, the elastic inclusion of a

00166 inside the contour of the ampoules spit molded spout

00167 formed in a transverse blind hole

00168 of the bearing socket extends. The so-joint cross

00169 ampoule head is safe in the elastic receiving

00170 held stationary while the vial body in a the

00171 release the liquid component-making Stürzlage

is pivoted 00,172th The bearing bush is axially from the bearing

00173 trim removable, which because cleaning- or sterilized

00174 sierungszugänglich, multiple use of Vorrich-

00175 tung opened. Schießlich is proposed that the displacement of 00176 to housing bearing connection as is Drehbewe¬ 00177 and realizes supply stop-limited. Finally, the invention provides 00178 nor in the proposal that the housing 00179 is in insertion position for the break ring ampoule 00180 parallel to the longitudinal direction of the chamber. This loading position 00181 also arises due to the standing position sugge¬ 00182 anti-cross base plate so that operating errors are virtually eliminated 00,183th Finally proper 00184 utility function is accomplished by a longitudinally slotted 00185 the clothes against the piston closing the locking ring. The 00186 mix can not pass behind the piston that. 00187 00188 The object of the invention is explained with reference to a 00189 graphically illustrated Ausführungsbeispie¬ 00190 les detail.

00288 local end portion of the inner wall 7 of the kammerbilden-

00289 the sleeve 6. The head plate forming the actual

00290 part of the cap 16 is in a rotating handle

00291 over, also ensued with the to increase the grip

00292 overlooked knurling 18 00293

00294 The chamber 1 includes a longitudinally displaceable manner therein

00295 latter arranged piston 19 over can be the

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

Ejecting 00297 aperture 8 therethrough. The piston displacement

00298 is via a both ends rotatably mounted thread

00299 may spindle 20. A rotary driving the piston itself

off 00300 on longitudinal guides on the inner wall 7

be the 00,301th In the exemplary embodiment, such means

00302 not shown. It has been found that the piston 20

00303 sufficiently frictionally and non-rotatably in the

00304 cylindrical chamber 1 is maintained. is promoted

00305 this rotation even by one of the outer wall of the

00306 piston 19 associated piston ring 21. In noncircular

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

00309

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

00311 externally accessible plunger actuating handle 22,

00312 over which to rotate the threaded spindle 20

00313 is. This is indirectly through a centrally located

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

00316 00317 M.

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

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

00320 displaceable disc 24 designed. The relatively thin,

00321 xx lying transversely to the longitudinal central axis of disc 24 can

00322 over the entire free inner length of the chamber 1

moving 00323, ie, starting from the inner side of the ring

00324 shoulder 9 until just before the pressure surface 25 of the

00325 piston 19, which in the basic position on the endbegrenzt

00326 inside of the head plate Toggle ie cap 16

00327 is, therefore, against the inside of the closure cap sixteenth

00328 The displacement direction of the mixing element M is by

00329 double arrow y indicated. 00330

00331 The rod 23 is overall in the hollow threaded spindle 20

00332 leads. The edge of the Sun over the centrally managed rod

movable 00333 23 also performed on the threaded spindle 20

00334 th slice 24 ends in a radial, a small

00335 gap loaded send distance in front of the inner wall 7 of the

00336 Chamber 1. Here, the mix happen. The disc

00337 24 is, as can be seen in Figure 7, also rich

broken 00,338th is formed which, according to the aperture

00339 equiangularly arranged distributed Archer 26th

00340 The latter form a rich lattice structure so that a

00341 severe, uniform mixing effect arises up

00342 base of the corresponding punch-through. As concen-

00343 tric arc slots realized Archer

00344 angeord- 26 are in two or more concentric rows

net 00345, angularly equal and left Radialbrük-

00346 ken 27 between continuous circumferential rings 28. The

00347 radial bridges 27 extend on the Winkelhalbie-

00348 leaders of the neighboring Archer 26. It shall in any

00349 Weil four Archer realized in an annular row. 00350 From the inner ring 28 here is the connection of the disc

00351 BE DONE 24 to the inner end of the rod 23 towards

00,352 men. The disk 24 is rotationally fixed with this

00353 connection. It is also about the local area, the

00354 given rotationally fixed connection to the threaded spindle 20.

00355 The threaded spindle 20 stands, as already angedeu-

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

00357 23rd 00358

00359 The coupling is achieved by wing 29th Latter

00360 going inwardly from ring 28 of the disc 24 innnenliegenden

00361 from. Here are just two in the diametrical arranged

00362 wing 29 realized. The clutch can be sought

00363 practically realized with only one wing 29th

00364 Also, more than two wings 29 are in principle conceivable

00365 bar. 00366

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

00368 screw 20. The wings 29 form also bridges

00369 of the mixing element M. It can be seen, according to the longitudinal

00370 slit 30 in the longitudinal central axis xx of the cylinder

00371-cylindrical chamber 1 takes place displacement of the rod

00372 23 disability-free for the mixing process explained

00373 given. 00374

00375 The head plate-side termination of the threaded spindle 20

00376 a sleeve-shaped end portion 31 forms thereof.

00377 Here, then, there remains a round closed cross section

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

00379 an end portion which in the basic position of the piston 19

00380 mainly a topfeinwärts directed collar 32

00381 of the piston 19 penetrates. The collar 32 and, where appropriate, 00,382 of the pressure surface 25 generating bottom of the

00383 pot-shaped piston 19 with the thread containing the

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

00386 failed Schlitzungsabdichtung bottom is gewindebil-

00387 DEND not included. 00388

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

00390 occurs there in a bearing support 34. The bearing mount

00391 34 is at one of the top plate of the closure cap

00392 16 outgoing, kammereinwärts directed spigot 35

00393 formed. The latter has such an axial length,

00,394 that he also has the facing in the opposite direction Bund 32

00395 includes radially supporting manner of the piston 19 and so the

00396 piston in its initial movement also leads peripherally.

00397 It is a very stable support of the concentric

00398 interlocking or -geschachtelten parts before. 00399

00400 Against the front end of the remote end of the Gewindespin-

00401 dei 20 is a seal member 36, which

00402, the mantle wall of the cylindrical rod 23 sealing

00403 encloses. For passage of the rod 23 is located

a central 00404 in the head plate of the closure cap 16

00405 bore 36. 00406

00407 The operating handle 22 is designed as a crank.

00408 Your perpendicular to the longitudinal mid-axis xx standing crank

00409 arm 38 is in the opposite direction to a achsgelager-

00410 th knob 39 continues in a similar arm's length, so

00411 that a cross handle is formed, the higher Betätigungskräf-

00412 te makes transferable, and notably in regard kolbenver-

00413 anlaßten discharge of the multicomponent product I / II.

00414 A chamber side lying receiving port 40 for the

00415 freely projecting end of the rod 23 is of such length,

00416 that there is a sufficient free space between the gripping

00417 chamber 1 and the crank arm 38 remains. 00418 00419 Storage of fußplattenseitigen end of the thread
