A pharmaceutical aerosol formulation containing pre-micronized epinephrine, a co-solvent ethanol, a surfactant polysorbate 80, and a propellant trans-1, 3, 3, 3-tetrafluoropropene (HFO-1234ze (E)) for use in a pressurized metered dose inhaler is described. The formulations provide efficient delivery of pre-micronized epinephrine particles into the respiratory tract of a patient, and have the advantages of high therapeutic efficacy, improved safety, and low global warming potential (GWP) affecting the environment.

The invention provides a quantitative aerosol inhalation system, which comprises a mouthpiece, a tee joint, a filter, an atomization device, an electromagnetic valve and a one-way valve, and is characterized in that the system is arranged in the tee joint, when a user exhales from the mouthpiece, the one-way valve is opened, airflow flows out of the filter through the one-way valve, when the user inhales, the one-way valve is closed, and the user can only inhale gas flowing in from the atomization device; and the control module is used for receiving the gas pressure value detected by the pressure detection element and controlling the action of the electromagnetic valve according to the gas pressure value. By means of the quantitative aerosol inhalation system, it can be ensured that aerosol administration is conducted on each patient under the optimal inhalation flow, once the inhalation flow is lower than the optimal flow range, administration is stopped immediately, and the accuracy of aerosol administration is greatly improved; meanwhile, the unique one-way valve design is adopted, and cross infection is eradicated; the dosing dosage can be automatically calculated, so that different dosing dosages can be generated by using a single concentration, and the gallipot does not need to be frequently replaced.

The application provides a quantitative injection device, and relates to the technical field of medical injection devices. The quantitative injection device comprises a shell, a dose sleeve, an indicating piece, a rotating assembly, a push rod assembly and a threaded sleeve. The dose sleeve is sleeved on the shell, the rear end of the dose sleeve is provided with a first ratchet, and the dose sleeve is in threaded transmission with the shell. The indicating piece is installed on the shell, and is used for indicating the dose of a medicament. The rotating assembly is installed on the dose sleeve, the rotating assembly is provided with a second ratchet which is engaged with the first ratchet, and the front end of the rotating assembly is provided with a third ratchet. The push rod assembly is installed on the rotating assembly, the push rod assembly is provided with a fourth ratchet which is engaged with the third ratchet, and the rotating assembly can drive the push rod assembly to rotate. The push rod assembly can move in the front-rear direction relative to the threaded sleeve. The embodiment of the application can solve the problem that the injection dose cannot be steplessly adjusted.

A respiratory delivery care system is characterized by comprising: a mechanical flow indicator movable in response to a user's inhalation and / or exhalation, and an electronic indicator operable in response to an electronic signal transmitted in response to the movement of the flow indicator. The flow indicator is an inspiratory valve, an expiratory valve, or an axially movable actuator. The delivery device includes a retaining chamber wound with a coil and at least one magnet disposed at the center of the coil, the at least one magnet being reciprocating to sense current and store the current in a supercapacitor connected to the circuitry and the electronic indicator. A respiratory delivery device is characterized by comprising: a flow indicator configured to transmit a first input signal, a metered-dose inhaler in communication with the retaining chamber, a lever for actuating the inhaler and having a sensor to transmit a second input signal, and a processor for receiving these signals to generate an output signal.

The present invention provides a stable pharmaceutical composition to be used with pressurized metered dose inhalers comprising a beta 2 agonist, a corticosteroid, a muscarinic antagonist, HFO propellant, a co-solvent, an organic acid(s) and optionally water. The invention further provides a specific container and a valve system comprising internally coated canister and a valve for storing the composition. The invention also provides a pharmaceutical composition comprising a beta 2 agonist, a corticosteroid, a muscarinic antagonist for the treatment or prophylaxis of asthma, chronic obstructive pulmonary disease (COPD), rhinitis or as adjunct therapy for cystic fibrosis, non-cystic fibrosis bronchiectasis, lung infections or pulmonary fibrosis.
