A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.

In some embodiments, a method includes establishing a communications link between a computing device and an adapter. The adapter is configured to receive at least a portion of a medicament delivery device. A wireless signal is received to maintain the communications link. A relative position between the computing device and the adapter is determined. An alarm is produced when the wireless signal is not received within a time period. The alarm is based on the relative position between the computing device and the adapter.

A nasal delivery device can include a nasal prong and an activation member. The nasal prong can have an opening at a top and bottom portion of the prong to allow for the passage of an aerosolized treatment agent through the nasal prong. The activation member can be positioned on the nasal delivery device at a location that is spaced apart from the subject's oral cavity when the nasal prong is received into the nostril of the subject. The activation member can detect a desired exhalation state of the subject and upon detection of the desired exhalation state, the activation member activates the delivery of the aerosolized treatment agent.

A drug receptacle for use with a respiratory inhaler device. The drug receptacle has a fluid flow rate indicator on an outer surface thereof. The fluid flow rate indicator comprises a corrugated portion having at least one and preferably a plurality of corrugations extending radially from the outer surface of the drug receptacle. The flow rate indicator is operable to generate a sound signal. The present invention also relates to a corrugated flow rate indicator having a connection portion for connection to the outer surface of a drug receptacle.

An atomization system and an atomization method are provided. The atomization system having an authentication mechanism includes an atomized drug container, a user device, and an atomizing device. The user device includes a communication module, an optical authentication module and a first acoustic wave communication module. The optical authentication module is configured to perform a first optical authentication operation associated with an authentication code carrier to obtain first optical authentication information, and the communication module is configured to request a cloud server to perform an authentication operation for the first optical authentication information to determine the authenticity of the atomized drug container.

The present invention provides a training device for training a user to use a pressurised metered dose inhaler (PMDI). The device comprises a body, air expulsion means (e.g. bellows) for expelling air along an air flow path and an actuator for actuation of the air expulsion means. The air flow path comprises a restriction such that upon expulsion of air along the air flow path, an audible signal is generated. The audible signal mimics that generated during use of a PMDI.

An automatic injection device includes an injection syringe for injecting liquid provided with a syringe body carrying an injection needle and a piston rod mounted to be able to move inside this syringe body to cover an injection stroke during which the liquid is injected, an external casing and a positioning control member that are telescopic, the relative movement of which controls the operation of the automatic injection device, and control members arranged to selectively control the movement of the syringe body and the movement of the piston inside the positioning control member in order to automatically inject the liquid present in the injection syringe, the automatic injection device further comprising a device for generating sound signals activated during the automatic injection of the liquid present in the injection syringe so as to generate a series of sound signals from the start to the end of the injection.

An inhaler or add-on device for an inhaler for dispensing a medicament to be inhaled. The inhaler or add-on device has a housing (H) with an air inlet (A_I), and an air outlet (A_O) for outputting air to be inhaled by a user. The housing (H) defines a flow path (FP) between the air inlet (A_I) and air outlet (A_O), and a passive acoustic element (PAE) is arranged in this flow path (FP) inside the housing (H). The passive acoustic element (PAE) has a structure having one or more structured gaps arranged to be passed by an air flow and it is dimensioned such that air flow passing it will generate sound (S) with pre-determined characteristics depending on the air flow speed. This allows acoustic monitoring of air flow passing the first passive acoustic element (PAE) external to the housing (H) by capturing and processing sound generated.

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by transporting carriages between various substations at which parts are added to a base. In another assembly method, the base may be moved between a plurality of robots which direct the base downwardly into contact with components to couple the components therewith. An inspection system may inspect the cartridges at various stages of completion.

An injection device and an injection device trainer for training a user to use an injection device. Each one of the injection device and the injection device trainer can include: a body portion; and an actuator positioned towards a proximal end of the body portion, the actuator moveable from a proximal position to a distal position; wherein the body portion comprises a body protrusion and the actuator comprises a latch that is arranged to couple with the body protrusion when the actuator is in the distal position, thus holding the actuator in the distal position.
