A vapor sample collection apparatus and method of vapor sample collection. The vapor sample collection apparatus has a connection port to connect a first end of a tube to an exhaust port of a vaporizer device, a vacuum pump connected to a second end of the tube, a manifold connected to the vacuum pump, and a vapor containment vessel for collecting a vapor sample, where the vacuum pump is configured to draw a predetermined pressure on the tube. The method of vapor sample collection includes connecting a connection port to an exhaust port of a vaporizer device, the connection port being attached to a first end of a tube, activating the vaporizer device to vaporize a sample containing an active ingredient, drawing a predetermined pressure on a second end of the tube using a vacuum pump, and collecting a vapor sample from the vaporizer device in a vapor containment vessel.

A vaporizer profile management system (VPMS) includes a vaporizer device with an electronic memory to store vapor production data (VPD) from a vape session, a communications interface to transmit the VPD to a computing platform, a vapor analyzing device to generate vapor content data (VCD) derived from vapor collected during the vape session from an exhaust port of the vaporizer device, and a computing platform that receives and processes the VPD and the VCD. A method for generating a vaporizer profile includes storing VPD from a vape session, transmitting the stored VPD to a computing platform, generating VCD derived from vapor collected during the vape session from an exhaust port of the vaporizer device, receiving the VPD and the VCD by the computing platform, and processing at the computing platform the VPD and the VCD to analyze and correlate the VCD with the VPD.

A device for delivering a predetermined volume a substance within a body cavity. The device includes: at least one predefined volume sized and shaped to contain a predetermined volume the substance; a delivery end in fluid communication with a container; and at least one valve mechanically connected to the container and configurable between an active configuration in which the valve enables delivery of a volume of the substance and an inactive configuration, in which the valve prevents delivery.

An inspection machine checks and inspects whether an infusion pump is accurately operated and does not require maintenance in a closed system without drainage. This inspection machine includes a syringe and a plunger and moves the plunger backward when an infusion flows into the syringe through a communication hole by the driving of an infusion pump to measure a flow rate by the backward movement amount. An outer peripheral surface of the plunger has an annular recess and a seal ring is fitted thereto. The seal ring is expanded by receiving a liquid pressure of the infusion to be sealed and the plunger is coaxially centered on the syringe. The flow rate of the infusion is accurately reflected to the plunger movement amount. Further, since the infusion is stored in the syringe and does not drip, drainage equipment is not required and an inspection operation can be performed anywhere.

An electronic cigarette includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater, at least one air inlet operable to deliver air to a central air passage upstream of the heater, and a mouth end insert having at least two diverging outlets. The electronic cigarette can also include an air flow diverter which directs incoming air away from a heating zone of the heater.

With a nebulizer mesh selection method it is possible to achieve optimal treatment which fits a medicine and a patient. A nebulizer mesh selection method includes a step of acquiring a medicine attribute, by a computer, a step of acquiring a patient breathing ability, a step of selecting a mesh that corresponds to the acquired medicine attribute and patient breathing ability based on a mesh selection table in which a predetermined mesh corresponds to a combination of a medicine attribute and a patient breathing ability, and a step of outputting the selected mesh.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on dimensions and a distensibility of a non-occluded portion of the patient line. If the change in pressure, the incremental volume, properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, a location of the occlusion can be inferred. An occlusion type can be inferred based on the inferred location.

A device for determining delivery of an aerosol stream has a collector having a filter for collecting aerosol particles in the aerosol stream, a first fluid connection point connectable to an aerosol generator, and a second fluid connection point connectable to a breathing simulator for simulating tidal breathing, at least one measurement volume for an interaction of at least one light beam with the aerosol particles passing through the measurement volume, at least one optical measurement unit for generating at least one optical measurement signal depending on the interaction of the at least one light beam with the aerosol particles passing the measurement volume, and at least one evaluation unit for determining the aerosol delivery of the aerosol stream from the at least one optical measurement signal. A method determines an absorption and/or adsorption of a liquid on aerosol particles.

A method for the inspection of a condition, in particular for the detection of defects, of a cannula (or injection needle) mounted on a syringe, which is located under a protective cap, and devices for carrying out such methods. A method includes measuring a magnetic field, in particular a magnetic field distribution, in the vicinity of the cannula. The presence of a ferromagnetic cannula causes a local change in the course of the magnetic field lines. This can be measured and used to determine whether the cannula, as desired, is arranged straight and coaxially to the syringe longitudinal axis, or whether it has a defect, such as being bent, kinked, compressed, broken/severed, oblique to the longitudinal axis of the syringe or eccentric to the longitudinal axis of the syringe.
