A respiratory flow therapy apparatus including a sensing chamber which measures a flow of gases provided to a patient. The sensing chamber can be located after a blower and/or mixer. The sensing chamber can include an ultrasonic transducer, a temperature sensor, a heated temperature sensing element, and/or a gas concentration sensor. A flow path of gases used in conjunction with the sensor system prevents unwanted vorticity in the flow of gases that can create anomalies in measuring flow.

A device places a plug and simultaneously checks a correct position alignment of the plug with a holding element for fixing a hollow body. The device has at least one first and one second opening and a plug placement mechanism with which the plug is be inserted into the second opening of the hollow body. The device has a measuring head that is traversed by at least one channel. The channel can be fluidically connected to the first opening of the hollow body. The device can further include a pressure sensor which can be fluidically connected to the channel of the measuring head.

The methods described herein provide improvements to the measurement of dose content uniformity of inhaler and nasal devices. The methods involve analyzing and measuring a spray pattern of an emitted spray from an inhaler or nasal device. The spray pattern may be used to determine the dose content uniformity of an inhaler or nasal device.

A system and method for determining a remaining processing capacity of a scrubber having a flow path and a processing material disposed along the flow path. A device may comprise a plurality of optical sensors disposed within the processing material and arranged along the flow path, a light source, and a processor for determining the capacity according to signals received from the optical sensor. The device may be used to illuminate processing material adjacent to each optical sensor using the light source, measure a light value reflected by the processing material at each optical sensor, and determine the remaining processing capacity of the scrubber, using the processor, based on the measured light value. Devices may comprise a memory, such as a non-volatile memory to allow multiple uses of a scrubber without reloading with fresh processing material.

Disclosed is an infusion pump which may include a native pumping mechanism to drive fluids through a functionally associated conduit, at least one native sensor to sense a physical characteristic of the fluid within the conduit and computing circuitry having a decalibration test mode to determine whether the infusion pump is decalibrated. The computing circuitry may be adapted to receive output from at least one native sensor during the decalibration test mode.

The present disclosure describes a personal vaporizer which can detect whether or not a cartridge of the personal vaporizer has been breached. The cartridge includes a conductive shell. The conductive shell can include two or more conductors which are electrically isolated from each-other. Prior to operation, the personal vaporizer can use the two or more conductors to assess whether or not an outer shell of the cartridge has been breached. In some implementations, if it is determined that the cartridge has been breached, the personal vaporizer can shut down, or otherwise fail to operate normally.

In a method and in an apparatus for the controlled delivery of particles, said particles are supplied to a measurement station in which the quantity of particles is detected. The particles are subsequently transferred by the measurement station to a dispensing device and are dispensed.

A non-burning type flavor inhaler includes: an aerosol source that generates an aerosol; an atomizer that atomizes the aerosol source without burning; a power source that supplies power to the atomizer; and a control unit that controls a power amount supplied from the power source to the atomizer. The control unit increases the power amount supplied to the atomizer stepwise from a reference power amount along with an increase in the number of puff actions for inhaling the aerosol.

Patient simulation system adapted for interacting with a medical apparatus, and method for operating the patient simulation system. A processing unit of the patient simulation system stores at least one physiological model of a patient in a memory of the patient simulation system. The processing unit receives at least one gas control parameter from the medical apparatus via a communication interface of the patient simulation system. The processing unit correlates the at least one gas control parameter with one of the at least one physiological model of a patient to generate simulated physiological effects. The processing unit further transmits the simulated physiological effects to the medical apparatus via the communication interface. In a particular aspect, the medical apparatus consists of an anesthesia apparatus.

The present invention relates to a displacement device, DD, for providing a displacement of a syringe closure system for a syringe relative to the syringe, a testing device, TD, and a method for leakage testing of a connection of a syringe closure system for a syringe with the syringe.
