Definitions

  • the invention relates to a device for dispensing at least one substance by means of an outlet valve from at least one crushable inner bag in an outer container.
  • Such devices are known in many forms and designs and are on the market. For example, noses or throat sprays are applied with such devices. This is done by means of a pumping movement, the substance being appropriately dispensed through the nozzle.
  • BEST ⁇ TIdUNGSKOPIE to reduce the risk of infection.
  • the substances are usually mixed with a preservative in an appropriate concentration so that penetrating, microbially contaminated air cannot contaminate the contents.
  • preservatives often has negative effects for patients and leads to side effects, such as allergic reactions or irritation, which should be avoided.
  • the present invention has for its object to provide a device of the type mentioned above, with which the application of the substances is facilitated, but the penetration of foreign substances is considerably more difficult.
  • the outer container is connected via an opening to a room whose volume can be changed.
  • the inner bag which contains the substance to be dispensed, is pressurized, so that even with minor leaks, no penetration of foreign substances and in particular no penetration of microbially contaminated air is possible. Furthermore, the dispensing of the substance is made considerably easier by the inner bag which is under pressure.
  • Pressurizing the inner bag can be done from the beginning by the bottler of the drug. However, there is a risk that if the device according to the invention is stored for a longer period of time, the pressure will drop so significantly that application of the substance is no longer supported. For this reason, it is contemplated within the scope of the invention that the user of the device himself can put the inner bag under pressure. For example, this is done in that a pressure bellows is provided on the outer container, by means of which air can be pressed into the space surrounding the inner bag via corresponding valve devices.
  • a cap is placed on the outer container, which cap is displaceable relative to the outer container. This creates a space between the outer container and the cap, the volume of which can be changed. By moving the cap relative to the outer container, air can be pumped into the outer container through a corresponding opening in the outer container. A check valve should be inserted in the opening so that this air does not escape again.
  • the outlet valve itself is also configured in the present exemplary embodiment as a pump valve.
  • a pump housing engages in the inner bag, which in turn is provided with a check valve in relation to the inner bag.
  • This check valve can also be a check valve.
  • the pump plunger preferably engages in a chamber in a nozzle head.
  • the volume of the chamber can be changed by the pump tappet, so that substance to be dispensed is expelled from the chamber through a corresponding opening. In the rest position, this opening is closed by a piston, which is supported on the one hand against the pump tappet and on the other hand against a spring.
  • a silver spiral is arranged in the flow path of this substance shortly before the outlet of the substance to be dispensed.
  • This silver spiral has a growth-inhibiting, killing and oligodynamic effect.
  • Each liquid molecule comes into contact with the silver element in the area of the outlet opening, which leads to a considerable reduction in the number of germs.
  • metallic sinter nozzle "KDF" which not only has a redox effect, but also has a physical germ and bactericidal effect.
  • dispense at least two substances together from at least two pressurized spaces by means of an outlet valve the substances mixing only shortly before or when they emerge from the outlet valve.
  • substances that should only come together at the moment of consumption For example, this could be insulin together with oxygen water and / or oxygen water together with a co-enzyme.
  • the main idea is to inhale the corresponding mixture so that the medication is absorbed through the lungs. In this way, the dose of the drug could be significantly reduced.
  • the device according to the invention for applying an intimate spray, nasal spray or as an oral irrigator.
  • each outlet nozzle is connected to a pressure chamber which contains the corresponding substance.
  • the substances are mixed before they are applied.
  • a mixing chamber or a mixing line is connected to both rooms in which the substances to be dispensed are located.
  • one substance is in a crushable inner bag, while the other substance is between the outer bag and inner bag.
  • it may be sufficient to only pressurize the space between the outer container and the inner bag in order to apply both substances together.
  • a displaceable nozzle body which has at least two inlet openings for the substance is located in a valve body.
  • Each of these inlet openings is assigned a seal for closing, the two seals being spaced apart from one another. This distance is selected so that when the nozzle body is moved, the inlet openings are opened at the same time, so that the substances to be dispensed are also applied together.
  • a return of the nozzle body to its initial position is granted by a spring which acts on the nozzle body.
  • Another outlet valve is intended to determine the mixing ratio of the two substances. This can be done in any way.
  • a pump piston is assigned to each space of a substance. If both pump pistons are operated together, the mixing ratio is 50:50. Will only be a piston only one substance is applied. Between these two extremes are all possibilities for setting a mixing ratio, which usually happens in that the pump piston, with which less substance is to be applied, is also acted on by a lower pressure. This can be done mechanically by a swash plate, which is inclined to the desired extent relative to the pump piston. But this is only one embodiment. All other possibilities lie within the scope of the invention.
  • the dispensing nozzles should be designed such that the substances to be dispensed are atomized.
  • a corresponding transform gate is used, which excites the substance to strong harmonics, so that it is atomized.
  • mist droplets are in the micro range so that they can reach the mucous membranes of the bronchi or nasal cavities or the lungs.
  • the corresponding transformer or resonator is supplied with energy via a button cell.
  • FIG. 1 shows a longitudinal section through an inventive device for dispensing at least one substance
  • FIG. 2 shows a partially illustrated longitudinal section through a further exemplary embodiment of an inventive device for dispensing a substance
  • FIG. 3 shows a partially shown longitudinal section through the device according to FIG. 2 in a different position of use
  • FIGS. 4 to 9 are perspective views of various devices for dispensing substances
  • Figures 10 to 12 are schematic views of a valve for dispensing two substances in different positions of use.
  • a substance to be dispensed is in a crushable inner bag 1, which is arranged in an outer container 2.
  • This outer container 2 is encompassed by a base shell 3, a cap 4 cooperating with the base shell 3.
  • the cap 4 is axially displaceable relative to the base shell 3, a displacement path of the cap being limited by an outwardly directed annular flange 5 on the base shell 3 and an inwardly directed flange 6 of the cap 4.
  • An outlet valve 8 with an outlet 9 is inserted into an upper opening 7 of the cap 4.
  • This outlet valve 8 has a nozzle head 10, in the axial recess 11 of which a guide bush 12 is inserted.
  • This Guide sleeve 12 forms with the nozzle head 10 a line 13 through which the substance to be dispensed can pass from a chamber 14 in the guide sleeve 12 through a radial opening 15 to the outlet 9.
  • the guide bushing 12 is surrounded by a silver spiral 16, the silver spiral 16 lying in the flow path of the substance to be dispensed.
  • a piston 18 which is supported against a spring 19.
  • the piston 18 closes the radial opening 15 in the relaxed position of the spring 19, so that the flow of the substance to be dispensed is interrupted.
  • a pump plunger 20 presses on the piston 18 and is slidably guided in the recess 11. At the other end, the pump plunger 20 engages in a pump housing 21 which is seated in the inner bag 1. At the end, this pump housing 21 is provided with a check valve, of which the valve ball is identified by 22.
  • the pump plunger 20 is supported within the pump housing 21 by means of a helical spring 23.
  • an attachment 24 is provided on the outer container 2, which enters into a snap connection with the outer container 2.
  • An annular seal 25 is provided for sealing between the outer container 2 and the attachment 24.
  • the attachment 24 is guided in an annular collar 26 protruding from the outlet valve 8. This prevents the cap 4 from tilting when pumping.
  • the operation of the present invention is as follows: To dispense the substance from the inner bag 1, it must be pressurized. This means that the space 27 between the inner bag 1 and the outer container 2 must be filled with a pressure medium. For this purpose, a pumping movement is exerted on the cap 4, so that the volume of the space 28 between the cap 4 and the outer container 2 is reduced. Corresponding air is pressed into the space 27 from the space 28 via an opening 29, so that a pressure is built up there.
  • the opening 29 is preferably provided with a check valve so that the pumped-in air remains in the space 27. In this way, a pressure can be built up in space 27 by the pumping movement.
  • This pressure causes substance from the inner bag 1 to reach a pressure chamber 30 within the pump housing 21 when the valve ball 22 is lifted from the corresponding valve seat. This fills the pressure chamber 30 and also a subsequent axial bore 31 in the pump plunger 20 and, if appropriate, the chamber 14 in the guide bushing 12.
  • the cap 4 is now moved together with the outlet valve 8 relative to the base shell 3.
  • the pump plunger 20 presses on the piston 18 and displaces it in the chamber 14 against the pressure of the spring 19. This opens the radial opening 15 so that substance to be dispensed can escape into the line 13 and out of the outlet 9.
  • the pump plunger 20 sucks in the substance to be applied continuously via the check valve into the pressure chamber 30 and pushes this substance to be applied via the axial bore 31, the chamber 14, the opening 15, the line 13 and the Outlet 9 off.
  • the outer container 2 can have a pressure bellows instead of the cap 4 be assigned, which for example covers the opening 29. Air can be continuously pumped into the interior of the outer container 2 via this pressure bellows.
  • Corresponding valves which serve to draw in outside air and to prevent the backflow of pumped-in air, are known and customary in the trade, which is why a more detailed description is dispensed with.
  • a corresponding outer container 2.1 is closed at the top by a valve plate 35.
  • this valve plate 35 there is an outlet valve 8.1, which engages in the interior of the outer container 2.1 in an inner bag 1.1.
  • the outlet valve 8.1 has a valve body 36 which is supported on the one hand by a seal 37 with respect to the valve plate 35 and on the other hand is inserted into the inner bag 1.1.
  • a nozzle body 38 is slidably arranged in the valve body 36 and is supported downwards against a spring 39.
  • the displacement of the nozzle body 38 is limited on the one hand by the spring 39 and on the other hand by an annular shoulder 40 which strikes a further seal 41.
  • a spacer 42 is provided above this seal 41.
  • annular space 45 which can be connected via a further radial bore 46 to an annular chamber 47, which is essentially formed by the valve body 36, the seal 37 and the spacer 42.
  • At least one inlet 48 which is connected to a second substance source, opens into the annular chamber 47.
  • Substance to be dispensed from the inner bag 1.1 is also in a space 49 around the spring 39 and is in front of the seal 41.
  • a second substance to be dispensed is located in the annular chamber 47 and is in front of the seal 37.
  • the nozzle body 38 is displaced axially toward the inner bag 1.1, as shown in FIG. 3.
  • the radial bores 46 and 43 pass over the respective seals 37 and 41, so that they allow the respective substance to engage from the annular chamber 47 into the annular space 45 and from the space 49 into the axial bore 44, as shown by the corresponding arrows ,
  • nozzles can be connected to the annular space 45 and the axial bore 44, so that the substances are applied separately.
  • Annulus 45 and axial bore 44 can also open into a mixing chamber, from which the desired substance is then discharged through a nozzle.
