Certain embodiments provide multi-medicament infusion systems for preventing the cross-channeling of medicaments. The system may include one or more of an infusion pump, medicament reservoirs, collars, a multi-channel fluid conduit, and an infusion set. The medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system selected configurations.

The present invention provides a drug delivery device (1) of the type in which a piston rod (10, 110) extends along a reference axis and is forced to rotate in an expelling direction about the reference axis during a dose expelling event to cause an expelling of drug from a drug reservoir (30, 130), and a resilient ratchet element (12) is operatively coupled with the piston rod (10, 110) and undergoes a deflecting motion comprising elastic deformation and recovery in response to an expelling of a predetermined dose increment, which deflecting motion occasions a velocity fluctuation of the piston rod (10, 110), comprising: a rotator module (50, 150) operatively coupled with the piston rod (10, 110) and configured to rotate about the reference axis against a rotation resisting force in response to a rotation of the piston rod (10, 110) in the expelling direction, the rotator module (50, 150) comprising a sensor system (70, 71; 170, 183; 270, 183) for monitoring a torque transferred by the piston rod (10, 110) during the dose expelling event, wherein the sensor system (70, 71; 170, 183; 270, 183) is configured to, from the monitored torque, identify occurrences of velocity fluctuation of the piston rod (10, 110) attributable to the deflecting motion of the resilient ratchet element 15 (12).

An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.

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 invention relates to an inhalation chamber including a body having an inlet orifice suitable for being connected to the outlet end piece of a metered dose inhaler and an outlet orifice suitable for being connected to a mouthpiece or a mask to apply on the face of a patient, and a support suitable for receiving the outlet end piece of the metered dose inhaler, the support opening into the inlet orifice, characterised in that the axis (X) of the inlet orifice is non-colinear with the axis (Y) of the outlet orifice and in that the support is pivotally mounted on the body around the axis (X) of the inlet orifice.

According to an aspect, there is provided a training device for use in an inhaler, the training device comprising a body that is configured to be received at a first position in a housing of an inhaler, wherein the body comprises an interface arranged to connect to a canister interface in the housing of the inhaler; an electrical circuit configured to perform one or more functions; and a circuit triggering mechanism that comprises a switch for enabling the electrical circuit to perform the one or more functions when the switch is closed, wherein the circuit triggering mechanism is configured such that the switch is closed when the body is pressed from the first position towards the canister interface and into a second position in the housing of the inhaler.

A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site, sensing a fluid parameter being applied to the tissue site, generating a fluid sensor signal in response to sensing the fluid parameter, and altering the fluid sensor signal in response to sensing that the fluid parameter changes. A fluid leak location mode may be entered. In response to the fluid leak location mode being entered, a graphical user interface that provides for fluid leak location functionality may be displayed. In one embodiment, the fluid leak location mode may be automatically entered in response to the sensor signal crossing a threshold value. Additionally, an alarm signal may be generated in response to determining that the fluid sensor signal crosses the threshold value.

Disclosed is an injection device for injecting a hypodermic syringe along an injection direction defining an injection axis. The injection device comprises a housing for being positioned at a user's skin, and a movable element movably arranged relative to the housing between a retracted position and an injection position.

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 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.
