Abstract: The invention concerns an ultrasonic atomizer (10), which is intended for an inhalation treatment apparatus for persons suffering from respiratory diseases. The ultrasonic atomizer (10) comprises an atomizer device (11) provided with a drug container (12) as well as an ultrasonic oscillator (13) connected to the container (12), the oscillator preferably comprising an oscillating crystal. The atomizer device (11) is provided with a duct passing into the patient, advantageously a mouth piece and an air-inlet duct (15). The atomizer device (11) comprises a pressure detector (36) directly connected to it or a duct (16) that is connected to the atomizer device (11) and passes to the pressure detector (36) and transmits the pressure of the breathing air. The pressure detector (36) detects the changes in pressure resulting from inhalation or exhalation of the patient, whereby, starting from the beginning of the inhalation stage, atomizing can be switched on by the apparatus.

Abstract: The invention concerns a respiration therapy apparatus used as a drug atomizer and/or a so-called respirator and/or as an oxygen dispenser. In the apparatus of the invention, administration to a patient of oxygen or air is discontinued, at the latest, when the exhalation phase begins. This has been implemented in the apparatus of the present invention by utilizing a pressure pick-up (22) observing differential pressure of the flow and which further provides control of an electromagnetic valve (23) which is disposed to close and to open a pressure line (16). At commencement of the inspiration phase, the differential pressure is transmitted over a signal connection (99) to the pressure pick-up (22). The pressure pick-up (22) further controls the electromagnetic valve (23), opening the pressure line (16).

Abstract: The present invention concerns a device for measuring the peak flow of a person's exhalation. The device comprises a frame structure which is provided with a mouth piece. Inside the frame structure, a flap is disposed, along with a pointer. A spring of the flap has been disposed in a hollow space in the lower part of the flap, where the spring is not in contact with the exhaled air. The frame structure comprises a frame part and a transparent cover part, whereby the hygienic conditions of the interior of the device can be observed, without any need to open the same.

Abstract: Respiration pacemaking valve apparatus adapted for use with apparatus for resuscitation such, for example, as a respirator, including a body member or housing defining a fluid flow passage, an inlet through which air or oxygen can be conducted into the fluid flow passage and wherein the body member is attached directly to a drug atomizer in a manner such that air or oxygen can be further conducted to the regulating valve assembly of a respirator or an outgoing connecting branch of other resuscitation apparatus. A spindle is disposed within the fluid flow passage of the body member which is provided with an elastic portion for opening and closing the fluid flow passage thereof in response to actuation of a trigger member pivotally mounted on the body member.

Abstract: Apparatus for atomizing medicaments includes a hollow body member defining a pair of open ended connecting passages which branch therefrom, a container member coupled to the body member for containing the liquid medicament, a nozzle member connected to the body member adapted to be interconnected to an external source of pressure and having a suction tube attached thereto which extends into the container member and a fixing member for locating the nozzle member in its appropriate position. According to the invention, the nozzle and fixing members are provided as separate members, both of which are connected to the body member in a detachable manner so that the apparatus can be disassembled in order to clean the intervening space, i.e., the space in which the liquid medicament is admixed with a pressurized gas flow, defined within the nozzle member.

Abstract: Respirator apparatus for assisting in the respiration of a patient who is indisposed or whose lungs are damaged includes a modular system to which various components may be added so that the same apparatus can be modified for various purposes. The respirator apparatus is a modular system comprising a basic unit, namely a drug atomizer and a control valve associated therewith which regulates the flow of air or oxygen to the drug atomizer. A flexible tube is fluidly coupled between a connector provided on the control valve and a pressure supply source.

Abstract: Valve apparatus for use in connection with a respirator or like apparatus, suitable for use in resuscitation, the valve apparatus providing a stepless or continuous adjustment of the counter-pressure presented to expiration by the patient.
