Dispensing container according to claim 4, characterized in that the hollow actuating rod (35) has at its inner end a normally in the blocking position valve body (48) which is responsive to the pressure in the hollow actuating rod (35) and in response to an increase in pressure can be moved into a release position. -

The invention relates to a dispensing container for connection to a catheter or the like. by means of which substances can be mixed and the mixture is dispensed.

Dispensing containers that have several compartments for separate storage of the substances and with which you can mix the latter and dispense the mixture are known (U.S. Patents 3,144,966 and 3 153531). These known dispensing containers may well fulfill their intended tasks, namely to mix and dispense sealants for industrial use, however, they are not suitable for medical tasks which include, among other things, the condition that the separated Substances thoroughly mixed within a total period of 45 seconds and placed in the body cavity must be given by a patient. In the known dispensing containers, the substances are through a mixing hole plate mixed from an actuating rod which extends through the dispensing opening of the container extends and normally closes the dispensing opening. The operating rod must therefore be withdrawn to release the dispensing opening after the mixing process, and around the Further manipulations are required to prepare dispensing containers for actually expressing the mixture.

The invention is based on the object of providing a dispensing container of the type mentioned at the beginning create that can be used simply and appropriately to mix the different substances and to apply the mixture, all within 30 seconds, without any special skill or even experience and practice are required, and of a simple, reliable, foolproof one and easy to understand step-by-step production of a desired plastic replica for enables a medical diagnosis.

According to the invention, this object is achieved by a dispensing container which is characterized by combining the following features:

a) A container has compartments for the separate storage of the mixture components and on his front end has a dispensing opening;

b) a mixing hole plate can be actuated from the rear end of the container in such a way that the mixing components be brought together;

A piston rod 62, which is provided at one end with a button 64 through the inner peripheral wall of the dispensing opening, is initially closed by means of opening 82. A substantial portion of the cord 65 releasably connected to the dispensing container valve body 75 protrudes forwardly out of the dispensing opening. The length of the piston rod 62 is so set that the protruding part of the is that when the button 64 is on the button 36 of the valve body with a rearward rests against the operating rod 35, the plug 46 is the The ring shoulder 84 showing the container 12 and a row of valve bodies 48 have reached and the catalytic converter is provided with bevelled, sharp-edged corrugations 85 almost completely in the first compartment 44, which is pressed as a "barbed hook" to engage. -. '■■■ .. inner circumferential wall of the flexible tube 14 die-The operating rod 35 is on its inner NEN. From Fig. 8 it can be seen that when the valve body 75 is permanently connected to a mixing hole plate 66 in the front, shown in full lines, which has a suitable shape to be in dependence on the locking position, the dispensing opening 82 from its back. and backward movement is completely blocked by means of the actuating device. If, on the other hand, the Ventilgungsstange 35 an effective mixing of the substances body in the clearance shown in dashed lines. As shown in FIG. 4, the order has been withdrawn, in which the ring school mixing hole plate 66 preferably has two openings 68 25 ter 84 on the front ring shoulder 86 of the nipple in two of its squares, and the remaining half 38 rests the mixture through the valve conveyor mixing hole plate is full. The actuating rod can be squeezed out through it, the mi * 35 initially extending displaceably through the schung through the radial opening 80 of the valve body displacement piston 34, flowing out to and fro.

As provided with an annular groove 70, which is best shown in FIG. 9, the pawl clip 72 cooperates when it has 88 a U-shaped body portion 90 that is desired to actuate the displacer 34. What is measured is that it extends by more than half. The snap ring is extended from one to the valve body 75 for this purpose. In the retracted position, the locking clip is moved forward into a position 40 made of a plastic with sufficient natural spring that it engages in the annular groove 70. When the tion is made so that it can releasably encompass the valve body snap ring 72 in the locked position, and also is. finds the clip, it lies on the back of the displacer piston - a ribbed flap 92, which acts as a hand, and the front side of the displacer piston serves to remove the locking clip,
bens lies against the mixing hole plate 66. When the catheter 10 with the connected permanent snap ring clamps the displacer flexible tube 14, which is reliably separated from the dispensing container 12 piston 34 against the mixing yoke plate 66, is inserted into the body cavity and its plastic sleeve 74, which the The actuating rod cuff is inflated, the first step 35 is loosely comprised, serves as a manual actuating device in preparation for the injection process, the direction in which the snap ring 72 is pulled out of its retracted 50 mixing hole plate 66 over about fifteen full strokes into its effectively engaged position the operating rod 35 to move back and forth position. 3 shows the snap path and then the mixing hole plate approximately in the ring 72 and the plastic sleeve 74 in their normal half of their last stroke. When that poses withdrawn. 7 shows the actuator in the first compartment 44 a longer period of time, the rod 35 fully retracted, with the risk of the liquid and mixing hole plate 66 separating against the front wall of the solid constituents. The purpose of this aiidrängerkolbens 34 is laid. Therefore, when the initial mixing process is that a hostange 35 is completely withdrawn, it is to produce homogeneous polymer,
The next step is to use the retracted position in the piston rod 62 in full lines in 60 to advance the plug 46 in the hollow position shown in Fig. 7 so that the actuating rod 35 forwards to press, where snap ring 72 is brought into engagement with the annular groove 70 by the valve body 48 in the release position. moved and the catalyst from the second compartment The discharge opening 82 at the front nipple 38 of the 45 is pressed into the first compartment 44. The piston-container is normally closed by a valve body rod 62 which is moved forward a maximum distance by 75, which is tubular, to allow pretty much all of the catalyst to flow through and displace it as a dispensing nipple. With the displacement of the catalyst in or connection piece, by means of which the container the first compartment 44 begins the period of time from

30 seconds during which the two ingredients must be thoroughly mixed. After this The mixture must be pressed out into the body cavity within an additional period of 30 seconds 15 seconds before the mixture begins to harden. A thorough one Mixing of the two ingredients is required and is accomplished by about 25 back and forth movements the actuating rod 35 causes over its full length. The introduction of the catalyst in the first Compartment 44 causes the displacement piston 34 to move slightly during the initial stroke of the piston rod 62 withdraws.

The mixing process is ended when the actuating rod 35 is fully withdrawn. the Plastic sleeve 74 is then moved from the position shown in FIG. 3 into the position shown in FIG moved forward to the snap ring 72 corresponding

to move accordingly and to engage in the annular groove 70, so that the displacement piston 34 is anchored on the actuating rod 35.

As the next step, the tab 92 of the locking clip 88 is grasped, the locking clip is removed and thereby the valve body 75 is released for axial displacement. When the locking clip is removed the corrugated end of the valve body 75 is inserted into the end of the flexible tube 14. At the

ίο Press the valve body 75 into the tube 14 the valve body is pushed back into its release position. The operator does not need any extra time, to open the valve. When the valve body is in its release position, it moves Operate the displacement piston 34 as far forward as possible by means of the actuating rod 35 to express the mixture through flexible tube 14 and catheter 10 into the body cavity.
