DETAILED DESCRIPTION
[0074] Example embodiments will now be described more fully with reference to the accompanying drawings.
[0075]
[0076] The inner wall 7 can be semi-permeable, perforable and/or porous or have predetermined breaking points, at least in sections. In this way, a fluidic connection between the first and second cavities 5, 9 can be or is established. If the side wall 3 has one or more intermediate walls, the intermediate walls can also be semi-permeable, perforable and/or porous at least in sections or have predetermined breaking points.
[0077] The capsule 1 may have a coating 11 on an inner surface, for example of the inner wall 7 or the lid 2 or the bottom 4, at least in sections. The coating 11 may comprise, for example, a complementary chemical agent capable of reacting exothermically with the chemical reactant. It may also be provided that the inner surfaces of the first and/or second cavities 5, 9 comprise, at least in sections, a coating 11. In at least one embodiment, at least one inner side of the first cavity 5 has, at least in sections, a coating comprising a complementary chemical agent, wherein the excipient 10 comprises a chemical reaction agent in the second cavity 9 and a propellant gas is received in the second cavity 9. If the second cavity 9 is opened to the first cavity 5, for example by perforating the inner wall 7, the chemical reaction agent can be introduced into the first cavity 5 by the propellant gas and can react exothermically there with the complementary chemical agent, so that the active substance 6 is heated and vaporized.
[0078] Preferably, the capsule 1 may be impermeable to air, i.e., when the lid 2 is closed, the first and/or the second cavity 5, 9 may be fluidically separated from an environment of the capsule so that, for example, no air from the environment can enter the respective cavities. The lid 2 may be perforable. Alternatively, the lid 2 may be porous and/or semi-permeable. However, it may also be that the lid 2 comprises predetermined breaking points and/or valves. Thus, a fluidic connection of the first and/or second cavity 5, 9 through the lid 2 to the environment of the capsule 1 can be established.
[0079] The capsule 1, in particular the side walls 3 and/or the inner wall 7 and/or the outer wall 8, can at least partially consist of or comprise glass and/or a transparent plastic. This allows, for example, the state of the active ingredient 6 and/or the excipient 10 to be visible or examined from the outside without opening the capsule 1. It may be provided that the inner wall 7, the outer wall 8, the lid 2 and/or the bottom 4 comprise viewing windows. If both the inner wall 7 and the outer wall 8 have viewing windows, these may be arranged overlapping in a radial direction as viewed from a capsule axis, so that the first cavity 5 can be visible from the outside through the second cavity 9. It may be provided that the outside of the capsule, in particular any viewing windows that may be present, is at least partially coated with a UV filter. The outside of the capsule 1 may also be at least partially coated with a thermochromic material.
[0080] The capsule may be substantially cylindrical, conical, prismatic, truncated pyramidal, truncated pyramidal, cubic, cuboid, paraboloid, or the like.
[0081]
[0082]
[0083]
[0084]
[0085] It may be provided that the first and/or second capsule opening device 104, 107 is shaped or set up in such a way that, when the capsule 1 is inserted into the capsule receptacle 103, the inner wall 7 is opened by the first and/or second capsule opening device 104, 107 in such a way that a fluidic connection between the first cavity 5 and the second cavity 10 results. For example, the inner wall 7 may have predetermined breaking points suitable for this purpose. Alternatively or additionally, the inner wall 7 may be at least partially semi-permeable so that, for example, the vaporized auxiliary material 10 can pass through the inner wall in the direction of the first cavity 5 or can enter the cavity through the semi-permeable inner wall 7.
[0086] In the embodiment shown in
[0087] For example, the reservoir 106 may be a replaceable cartridge. However, the reservoir 106 can also be a tank or container that is permanently installed in the vaporizer 100, preferably one that can be filled from the outside. The introduction of the fluid stored in the reservoir 106 through the second capsule opening device 107 into the capsule may, for example, be effected by gravity, optionally with the flap 111 open. However, it may also be provided to create or assist the introduction by positive pressure, for example by a pump, compressor or the like not shown in
[0088] The cooling device 112 may be or include a cooling coil. Alternatively or additionally, the cooling device 112 may have cooling fins. It may also be provided that the cooling device 112 comprises a fan, for example a fan. Alternatively or additionally, the cooling device 112 may comprise evaporative cooling. It may be provided that the cooling device 112 is controllable by the control and/or regulation unit 116 so that the cooling capacity is variable or adjustable and can be regulated or controlled.
[0089]
[0090] The capsule 1 can be fixed in the capsule receptacle 103 by a pivotable plate 123 shown in
[0091] The cooling device 112 may include a fan, blower, or the like, as shown, for example, in
[0092] An atomizer 114 is arranged between the mouthpiece 101 and the reservoir 113 in the embodiment shown in
[0093] The atomizer can atomize the vaporized active ingredient and/or excipient into intrathoracic (respirable) aerosol particles, where the particles can preferably have a diameter between about 0.5 and 5.5 μm.
[0094] By pulling the mouthpiece 101 and/or a positive pressure in the reservoir 113, a small concentrated amount of active ingredient 6 and/or excipient 10 can be aspirated and/or introduced into the atomizer 114 and/or the suction tube of the atomizer 114. The atomizer 114 and/or the suction tube may have a venturi nozzle and/or air channels, so that the venturi effect during suction dilutes and/or atomizes the concentrated aerosol accordingly. This can increase the proportion of the aerosol fraction that is respirable quite considerably. In order to filter large particles, it is conceivable to set the aspirated air in rotation so that the large particles are deposited on the porous wall of the suction tube or are filtered out and separated there. Appropriate filters can also be fitted in the suction tube, which also control the flow rate of the active ingredient 6 and/or the excipient 10 by their density. The aerosol flow in the suction tube can be diverted around via a kind of labyrinth or labyrinth-like channel 118 with at least one additional breakaway edge, whereby droplets that are too large are separated not only as a result of gravity but also by their contact at such a baffle as a result of the detour.
[0095] The nebulizer 114 may also be or include a nozzle nebulizer, an ultrasonic nebulizer, or a membrane nebulizer. In nozzle nebulizers, a strong stream of air creates a negative pressure at a nozzle, drawing droplets from a capillary system. As the droplets vary in size, a baffle plate holds back droplets that are too large. Ultrasonic nebulizers use a vibrating piezo crystal to generate ultrasound, which is responsible for the formation of the droplets. The higher the frequency is selected, the finer the droplets become. The frequency, for example, is 1-3 MHz. Membrane nebulizers are characterized by a very thin membrane consisting of a large number of micro-holes, which vibrates in the kHz range. Due to these oscillations, each microbore acts as a small pump and produces the finest droplets.
[0096] The vaporizer 100 may include an accumulator, not shown, that supplies electrical power to the control and/or regulating unit 116 and any other components housed within the vaporizer 100 that require power. The vaporizer 100 may include a connector on an exterior surface for a power cable to charge the accumulator. Alternatively or additionally, the accumulator may be replaceable. Alternatively or additionally, non-rechargeable batteries may be provided.
[0097] The vaporizer 100 may at least partially comprise or have a transparent plastic. Preferably, the vaporizer 100 may be made of or have a transparent plastic at least in the region of the capsule receptacle 103 and/or the capsule receptacle 103 itself, or at least be transparent so that a capsule 1 inserted into the capsule receptacle 103 is visible from outside the vaporizer 100.
[0098]
[0099] The vaporizer unit 102 may alternatively or additionally comprise a microwave generator not shown in
[0100]
[0101] The embodiment shown in
[0102]
[0103]
[0104]
[0105] The at least one sensor 117 may be or comprise a temperature sensor, a pressure sensor, a sensor for measuring the flow velocity and/or a sensor for measuring the concentration of, for example, the active ingredient 6. At least one sensor 117 may be arranged in each of the first and/or second cavity 5, 9 of the capsule 1, the first and/or second capsule opening device 104, 107, the capsule receptacle 103, the reservoir 106, the respective connecting lines 121, the cooling unit 112, the reservoir 113, the atomizer 114, and/or the mouthpiece 101. The measured values measured by the at least one sensor 117 can be transmitted to the control and/or regulation unit 116 and evaluated by the latter. The actuating element 110, the reading unit 120 and/or the identification unit 119 may be connected to the control and/or regulation unit 116 and the acquired information, e.g. actuation of the actuating element, acquired code 14 or user identification information may be transmitted to and evaluated by the control and/or regulation unit 116. Preferably, the identification unit 119 may be or comprise a fingerprint sensor 119. The control and/or regulation unit 116 may control the vaporizer unit 102, the cooling unit 106, the flaps 111, and/or the atomizer 114.
[0106] The control may depend on the evaluation of the measured values and/or transmitted information and/or the information stored in the data memory performed by the control and/or regulation unit 116. If the code 14 contains, for example, information relating to the active ingredient 6, it may be provided that the open-loop and/or closed-loop control unit 116 determines an evaporation temperature from a database stored in its data memory and controls the evaporation unit 102 and/or the cooling unit 112 in such a way that the evaporation temperature is reached and/or maintained and/or not exceeded. Similarly, for example, the evaporating temperature may also be directly included in the code 14 and evaluated by the control and/or regulation unit 116. In some embodiments, for example, alternatively or additionally, information contained in the code 14 regarding the active agent 6 and/or the excipient 10 may be compared to the information of the individual user stored in the data memory to determine an authorization of the user to vaporize the active agent 6 and/or the excipient 10. If the user is not authorized, it may be provided that the control and/or regulation unit 116 does not control the vaporizer unit 102 and/or the flaps 111 so that the active agent 6 and/or the excipient 10 is not vaporized. For example, if the active ingredient 6 is or contains a drug to be vaporized, it can be ensured that the user does not ingest an incorrect or non-prescribed drug through the vaporizer 100 and/or that the dosage of the drug is the same as that prescribed. Similarly, the fingerprints captured by the fingerprint sensor 119 can be compared with information stored in the data memory regarding the individual user, so that the vaporizer can be used, for example, only by one or possibly several specific users. This may result in better hygiene in particular. It may be provided that the vaporizer 100 has a signal element, for example an LED, on an outer side, which signals unauthorized use or non-vaporization of the active ingredient 6 and/or the excipient 10. In some embodiments, the LED may also be configured to indicate, for example, a fill level of an accumulator of the vaporizer 100 or the like.
The features disclosed in the claims, the description, the figures and the abstract may be essential to the invention individually or in combination.
[0107] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
