Abstract: Medical tubes and methods of manufacturing medical tubes are disclosed, such as in positive airway pressure (PAP), respirator, anaesthesia, ventilator, and insufflation systems. The tube may be a composite structure made of two or more distinct components spirally wound to form an elongate tube. One of the components may be a spirally wound elongate hollow body, and the other component an elongate structural component spirally wound between turns of the spirally wound hollow body. Alternatively, the tube need not be made from distinct components. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or have other medical uses.

Abstract: A process and a signal processing unit determine a pneumatic parameter (Pmus) for the spontaneous breathing of a patient. The patient is ventilated mechanically by a ventilator. A lung-mechanical model (20) and a gradient model (22) are preset. The lung-mechanical model (20) describes a relationship between the pneumatic parameter (Pmus) as well as a volume flow signal (Vol?), a volume signal (Vol) and/or a respiratory signal (Sig), which can be measured. The gradient model (22) describes a value for the pneumatic parameter (Pmus) as a function of N chronologically earlier values of the pneumatic parameter (Pmus) or of a variable correlating with the pneumatic parameter (Pmus). N values for the correlating variable are determined at first. At least one additional value is subsequently determined for the pneumatic parameter (Pmus). N chronologically earlier values of the correlating variable, current signal values, the lung-mechanical model (20) and the gradient model (22) are used for this purpose.

Abstract: Apparatus and methods are described for use with a vaporizer that vaporizes at least one active ingredient of a plant material. In response to receiving a first input to the vaporizer, the plant material is heated, in a first heating step. An indication of the temperature of the plant material is detected, and, in response to detecting an indication that the temperature of the plant material is at a first temperature, the first heating step is terminated, by withholding causing further temperature increase of the plant material. The first temperature is less than 95 percent of the vaporization temperature of the active ingredient. Subsequently, a second input is received at the vaporizer. In response thereto, the plant material is heated to the vaporization temperature, in a second heating step. Other applications are also described.
