Definitions

  • the invention relates to the application of media, in particular pharmaceutical products in atomized, jet or drop form and a donor for it.
  • WO 96/24439 shows a disposable dispenser in which one liquid drug containing through a rubber stopper sealed glass ampoule is inserted into a sleeve that has a Breakage connection is connected to a donor.
  • This has a protruding nose adapter with a spray nozzle at the end.
  • a central shaft or stamp inside this adapter carries a needle in the middle, which is activated by manual pushing in the sleeve in the adapter pierces the rubber plug. The The shaft then presses the rubber stopper into the ampoule as a piston and thus generates the application pressure.
  • a thin hollow needle such as a steel needle
  • a metal adapter provided that on the outside as a relatively thick solid metal ring the needle has been attached. It allowed one to attack Assembly tool and was by means of an annular Locking teeth pressed into the shaft. This arrangement has changed proven and was due to the reliable assembly without Damage to the sensitive tip is considered inevitable. However, it requires the metal adapter as a separate part, which the Costs and also the metal content in what is otherwise almost sorted by type Donor increased.
  • This disposable atomizer is very reliable and for the application liquid medication, especially for those who should be absorbed by the body very quickly, e.g. through the Nasal mucosa, with also intolerances for the Digestive tract, which could occur with oral intake, avoided become.
  • there are drugs that are no longer in liquid form Time are stable.
  • US 3,756,390 relates to an injection syringe, the two by one Breakthrough foil separate spaces for liquid and Powder.
  • a nozzle connects to the powder chamber, into the after Removing a protective cap a needle can be used. To Breaking through the release film, the two media together mixed. Then the protective cap is removed, the needle used and carried out after the air-out spraying.
  • a similar procedure is in US 3,595,439 A for one Mixing cartridge for 2-component dental material.
  • GB 1 453 591 describes an ampoule which is pierceable End plug for a liquid chamber and one Has intermediate plugs to a powder chamber. When stabbing a needle connected to a drip, for example the intermediate plug pushed out so that both media can mix with each other. Through an extra channel, the Enter the mixture into the drip chamber.
  • JP 8-280807 A shows an adapter that is one of a Has aluminum foil sealed liquid chamber. This can placed on a container of freeze-dried pharmaceutical become. To the other side of the with a screw cap sealed adapter can be attached to a pump atomizer who pierces the aluminum foil with his suction tube and so Liquid chamber and powder container connects together. This to be assembled from three separate parts before use Dispenser is not very helpful for uncomplicated use.
  • the object of the invention is to provide a dispenser for dispensing to create at least two different media, the particular one easier and more cost-effective in terms of needle output is to be manufactured and assembled.
  • the invention defined in claim 1 enables the very thin and sensitive needle with the necessary tightness damage-free without attaching this adapter. To do this, she is between the entire central area between the two ends of the needle encompassing ribs of a larger bore in the shaft and at the end pressed into a hole with a press fit, which is a lot longer is than the needle diameter. It rests on one shoulder within this hole and can thus freely towards the outlet opening communicate. When inserting, the needle becomes the tip of it supporting end held by a collet holding a central pin has, which engages in the needle and thus a crush and Damage to the sensitive tip prevented. This is important because damage-free tip for piercing the sealing plug is just as necessary as with an injection needle to avoid that the needle penetrates the container or piston wall Detaches particles that clog the discharge opening or even into the Airways of the patient.
  • the invention also provides a dispenser in which a liquid is used Carrier medium used for a particulate solid medium and the separately stored media only before they are released be mixed together.
  • particulate Solid state medium is to be understood that it is not a gas, liquid, Paste or in solid form, but usually dry with one certain fluidity or flowability is present, in particular is powdery to granular. So it is possible the two media to be kept separately from each other, the active ingredient usually in the particulate medium can be present in dry form. It can e.g. is a pharmaceutical product that is in the form of a freeze-dried powder.
  • Carrier medium is used. It can either be a slurry (Dispersion) or a solution that then comes together is applied, preferably as a spray, but also as a drop or beam.
  • the liquid is chosen in this way can be that the absorption through the mucous membranes particularly is promoted. Preservatives can be dispensed with.
  • the particulate solid medium should best be powder, but at least flowable or free-flowing and with the liquid be easy to mix, so in the relatively short, available Intimate mixing or even solution in the liquid is possible at times is. But it is possible that the particles also in the form of so-called Microcapsules are present, i.e. from a skin covered Ingredients exist.
  • the solid state medium is usually the space in which it is is not filled in completely. This becomes a partial one relatively large volume of gas, such as air or of an inert gas promoting the stabilization of the product.
  • this gas can with the introduction of the liquid be compacted so that finally when they are spreading, i.e. opening the solid state storage or a mixing room already a certain There is initial pressure, e.g. for good atomization from the start at worries.
  • the dispenser can have a liquid space, pressure generating means for Generate a discharge pressure and to convey the liquid in a media storage for a separate from the liquid space powdery or free-flowing solid medium and one Have outlet opening for the mixture.
  • the pressure generating agent it can be a thrust piston pump, the cylinder of which Liquid space can be.
  • the dispenser 11 shown in FIG. 1 is a disposable atomizer that spreads its entire batch in one stroke. It has a housing 12, which has an elongated adapter section 13. It sticks out an oval in plan view, protruding on two sides epaulette-like actuation shoulder 14 of the housing in the middle.

Accordingly, there is in the ampoule 19 except one Media storage 43 sealing piston 26 a Separating liquid space 21 from the media store 43 Intermediate piston 55, the two in the rest state shown Separates spaces from each other. To connect them is a Wall of the ampoule 19 molded connection channel 35a provided that its exit in the media storage 43a in Idle state is completed by the intermediate piston 55.

  • This hole has one much larger diameter than the needle 37, however, this leads by e.g. four radially inwards from the inner wall of the bore projecting webs 59, which in the region of the end face 52 of the shaft 34 begin with an insertion bevel 60. They ensure accurate Centering and prevent the thin needle from kinking when Deploy. They range from the free end of the shaft to one Fitting bore 61, i.e. about the biggest and especially for preventing of the important central region of the needle.

  • the needle stands how to recognizes from the drawing only over a relatively small part of theirs Length, usually less than a third, from the shaft 34. So is the section most at risk of buckling, which is in the middle of the Needle lies when applying the force to press it into the Fitting bore 61 already guided against buckling between the ribs.
  • the sensitive tip 28 of the needle in the Pressing process is not damaged. Therefore, with one Tool worked that the needle with a kind from the outside Grips collet (in the area protruding from the shaft), but additionally has a center pin that goes into the needle bore engages and so the needle against crushing and damage to the Lace secures.
