The present invention relates to a disposable inhaler, in particular for the storage and delivery of substances dissolved in a gaseous medium into the airways by means of an internal cavity, also known as a suction channel, and a closure plate at one end and a siphon it has an impregnated foam layer and a spiral frame for temporary storage of liquid or powder material.

For drugs that act directly on the respiratory tract, inhalation dosing is obvious. Medication through the lung alveoli, because of its enormous total surface area, can also be beneficial for active substances distributed throughout the body. This is exacerbated by the fact that bypassing the liver and the digestive system, the active substance is circulated through the lungs to prevent the compounds from being degraded before absorption or rapidly inactivated in the liver.

Several classes of inhalation devices are known, in addition to those powered by an auxiliary power source, there are simple, portable devices that utilize the suction effect of the user's breathing.

Patent applications HU 200 105 and HU 189 813 relate to auxiliary power units consisting of several components. With these, the treatment of many patients can be realized in continuous operation. Their construction feature is that they are expensive and their operation is subject to special conditions.

A simpler inhaler is disclosed in HU 205 721. The ampoule in the device contains the active ingredient. When used, the ampoule is disrupted by an internal structure, after which the active ingredient becomes inhalable.

The disadvantage of this solution is that installation is a bit complicated and glass debris can get into the airways in case of failure.

In addition to eliminating the drawbacks of known inhalation devices, the purpose of the patented design was to provide an inhalation device which is simple in design, portable, easy to use without any particular expertise, and its low cost enables it to be used as a single use inhaler.

The patent version has led to the discovery that if the inhalate is impregnated in a carrier and has a specific geometry that is appropriate to both the storage and inhalation function, the intended purpose can be achieved.

The disposable inhaler, which is particularly suited for delivering substances dissolved in a gaseous medium to the airways by simple aspiration, has an internal suction port and a closure plate at one end and a lance connection at the other end and forming a tubular device body around the suction The spiral body is formed such that the sponge layer forms an impregnated insert for temporarily receiving liquid or powder material, and the spiral body is disposed between a sealing plate at the ends of the longitudinal axis of the suction channel and a ring-shaped lip contact plate.

A further feature of the patented inhaler may be that the flexible body of plastic or metal is placed in the foam layer instead of the helically disposed plates.

In another embodiment, the same function is provided if the wireframe is connected only at the inner or outer side of the sponge layer.

A further alternative is that the frame is connected by ring-shaped plates and elongated wire members which resiliently fix them, not spirally running plates.

In the design of the patented inhaler, it is advantageous for the foam layer impregnated with the inhalate to be sealed by a foil on the outside or inside, which can be fixed either to the spiral body or on the surface of the foam layer.

The use of the patented inhaler is further facilitated by the handle on the flap and the safety strap running inside, which prevents the device from being pulled out too much.

The patented inhaler has several advantages. Perhaps most importantly, its simple design allows it to be used without any special expertise, anywhere and at any time, without the need for additional aids or external power. It is also advantageous that it can be sterilized with suitable size and suitably selected materials, and that the active ingredient contained therein can be stored for a longer period without deterioration in quality. Another advantage is that it is space-saving when stored.

The patented inhaler will now be described in more detail with reference to an exemplary embodiment. In the drawing it is

Figure 1 is a sectional and partially sectional view of a possible embodiment in a storage and use condition.

Figure 2 is a schematic representation of the spiral frame

Figure 3 is a schematic view of a wire frame replacing a spiral frame.

Figure 1 illustrates a short cylindrical version of a disposable inhaler attachable to a skip. The storage status is shown on the right side of the illustration, while the usage status is on the left side. Cutting out part of the tubular structure also shows the structural members in section. The foam layer 2 impregnated with the liquid or powder active ingredient is bonded to the spiral body 3, forming together the wall of the suction port 6. The spiral body 3 is located between the closure plate 1 and the nip plate 5 at both ends of the longitudinal axis of the inhaler. In the embodiment shown in the figure, a thin plastic cover film 4 is attached to the inner and outer sides of the spiral frame 3. On the outside of the closure sheet 1 there is a handle 7 made of plastic fibers, while inside the sponge layer 2 there are arranged plastic stretching fibers 8, the end points of which are fixed to the closure plate 1 and the nipple connection plate 5. A circular opening is provided in the center of the nipple connector plate 5. Figure 1 shows that the length of the storage space is smaller, in which case the cover foil 4 covers the foam layer 2, while the left side of the figure

In the state of 77 774 Β, the teardrop remains of the cover film 4 are visible.

The inhaler of Fig. 1 is gas-tightly sealed during storage by the cover film 4. It is also typical that in this position the air content of the pores of the sponge layer 2 is low due to the slightly longitudinally compressed position. This condition is stabilized by the cover film 4 and the flexible spiral frame 3. Commissioning consists of attaching the inhaler connection plate 5 to the skip and extending the spiral body 3 by means of the handle 7. Following the rupture of the cover foil 4, a new position is formed by the longitudinal spring force of the spiral body 3 and the counter retaining force of the sponge layer 2 in the opposite direction. The pores of the sponge layer also open, allowing the user to draw in air through the skip. As a result of the suction, the ambient air entering the outer surface of the sponge layer 2 and passing through the sponge layer 2 towards the suction port 6 saturates the impregnated material and then passes through the nozzle to the airways where it can exert its healing effect.

Fig. 2 illustrates more precisely the spiral frame 3 of the patented inhaler 3, preferably made of plastic or hard paper, and its similar design as the spiral spring, and its attachment to the closure plate 1 and the nipple connector 5.

Figure 3 illustrates the shape features of a wire frame 9 which is identical in function, but is different in form, but consists of a double longitudinal metal spiral wire and the transverse wires connecting them. Similarly, a similar form of solution may be made of plastic of appropriate stiffness.

Numerous embodiments that accomplish a similar function are conceivable, particularly as regards the design of the cover film, and can be easily replaced by a rigid-walled housing, or by wrapping the entire unit. The essence of the solution, however, is not this, but a well-designed, transversely sufficiently rigid and longitudinally resilient frame structure forming a unit formed with a non-deformable foam pad at the suction.

This design also allows the user to easily control the rate of release of a liquid or finely powdered solid impregnated into the foam layer by the rate of inhalation and suction, so that such an inhaler is useful for treating a variety of respiratory diseases.
