Abstract: The inhalation atomizer of the invention has a valve box, which is divided into two sub-chambers by a partition wall. The valve box is closed by a valve box cover. A one-piece valve element projects into both sub-chambers and closes the openings provided in the sub-chambers and in the valve box cover in dependence on the breathing of the patient.

Abstract: A diaphragm assembly for the diaphragm pump of an inhaling apparatus compressor contains a flexible diaphragm 1,21 with a first opening 2, 22, a lower diaphragm disc 6, 26, with a second opening 8, 28, and an upper diaphragm disc 14, 38 with a third opening 16, 40, said diaphragm discs 6, 14, 26, 38 having a smaller diameter than the flexible diaphragm 1, 21, and a securement member 18, 44, for clamping the diaphragms 1, 21, between the lower diaphragm discs 6, 26 and the upper diaphragm discs 14, 38, said securement member 18, 44 being guided through the first, second and third opening 2, 12, 16, 22, 28, 40 and being in engagement with a diaphragm drive device.

Abstract: The present invention relates to a liquid atomizer device for producing aerosols. The device includes a first housing part (A) which includes an inner member (3) of an atomizer nozzle and a first connection for connecting the first housing part (A) to a further housing part to form a nebulizing chamber (1), and further includes a second housing part (B) that includes an outer member of the atomizer nozzle which can be brought into engagement with the inner member (3) to form the atomizer nozzle, and a second connection means (11) that can be brought into engagement with the first connection (9) for connecting the second housing part to the first housing part. The invention is characterized in that a service life indicator (L) is arranged at a place that does not impede the flow passing through the device, but is accessible to the aerosol and a sterilant.

Abstract: The present invention relates to a meter, especially a meter for metering aerosol devices, basically consisting of four disk units that are arranged in a parallel position and located on the same axis.

Abstract: The invention is directed to a portable inhalation device. This device is compact and portable and contains a compressor, an air filter and a power supply, and permits, together with an aerosol nebuliser, the mobile administration of drugs by inhalation.

Abstract: Propellant mixtures and medicament aerosols which contain them are described for micronizing medicaments for pulmonary use. The propellant mixture is in a subcritical state and contains at least one component from a first class of propellant gasses and at least one component from a second class of propellant gasses. The first class includes propellant gasses with an evaporation enthalpy of 200 kJ/kg or less at 25° C. and a vapor pressure of 20 bars or more at 25° C., and the second class includes propellant gasses with an evaporation enthalpy of 300 kJ/kg or more at 25° C. and a vapor pressure of 10 bars or less at 25° C. By using this propellant mixture in a medicament aerosol, micronized medicaments are obtained in which approximately 80% by weight of the generated particles have less than 8 &mgr;m diameter.

Abstract: A limiting valve (4) is provided in an inhalation therapy unit with a valve member (13) which closes an air through opening (12) in the idle state and corresponding to the pressure difference occurring over the valve opens same substantially proportionally up to a threshold value. If the threshold value is exceeded, the valve member (13) abuts against a limiting member (16) which limits the movement of the valve member (13) and the air passage orifices (17) of which are partially closed by the valve member (13) so that air can only flow through the air passage auxiliary orifices remaining free. In this manner the patient using the inhalation therapy unit is urged to breath in the range below the threshold value, as his respiration above the threshold value is opposed by a considerably higher resistance.

Abstract: The invention relates to a breath simulator, which comprises a pump means (1) and a computer means (3). The computer means (3) controls the pump means (1) in such a manner that a stored breathing pattern of a patient is produced on a connecting piece (12) of the pump means. With the aid of the breath simulator, therapeutical nebulisers can be examined.

Abstract: The invention relates to a device for atomising fluids and having a bottom part (1) and a top part (2) disposed so as to be axially symmetrical with the bottom part, and comprising an intake air arrangement (3) and an outlet nozzle (4). The atomiser according to the invention also has an insert (5) for receiving a fluid (23) and a nozzle arrangement (6) disposed so as to be axially symmetrical with the intake air arrangement (3). The intake air arrangement (3) has a hollow cylindrical duct (7) with a conical widening (8) towards the incoming air end. As a result of being constructed according to the invention, the atormiser is particularly suitable for local inhalation anaesthesia, e g. in preparation for examination of the bronchi.
