There is provided a respirator for supplying clean air for a wearer. The respirator comprises a face assembly comprising an oronasal mask configured to seal against and cover a nose region and a mouth region of the wearer. The face assembly may be configured to be interchangeable on the respirator between a half-face assembly and a full-face assembly. The respirator comprises a securing headgear releasably securable with the face assembly, the securing headgear assembly configured to secure the respirator on a head of the wearer. The respirator comprises a facepiece assembly for supplying the wearer with air for inhaling and releasing air exhaled by the wear, the facepiece assembly releasably securable with the face assembly. One or more of the face assembly, the facepiece assembly, or the securing headgear are configured to be released from the respirator, sterilized, and releasably resecured with the respirator.

A portable rescue inhaler having a first canister containing a gas mixture of helium, oxygen, and nitrogen, and having a second canister containing an aerosolized medicine. The gas mixture of helium, oxygen, and nitrogen contained in the first canister has a density slightly lower than the density of atmospheric air. The portable rescue inhaler is capable of delivering the lower density gas mixture simultaneously with the aerosolized medicine for emergency hand held rescue of patients suffering from asthma, asthmatic bronchitis, COPD, emphysema, cystic fibrosis, and myocardial insufficiency. The portable rescue inhaler is capable of providing a vaporized anesthetic for greater medical assistance for patients in need of anesthesia due to respiratory insufficiency. The portable rescue inhaler reduces intra-operative risks in respiratory patients prior to gaining access to a hospital or care center.

The invention provides compositions, kits and methods for depositing a composition comprising a plurality of magnetic particles, to a target site of a subject by delivering the composition via controlled inhalation to a region of the subject's respiratory tract and applying a magnetic field to a target site within the region of the subject's respiratory tract to capture the particles in said target site.

Proposed is a ventilator medication injection structure. The structure includes a T-tube (10) which has a tube body that extends from an inlet (11) to an outlet (12) and which has a branch tube (13), a cover (20) having a first tube body (22) formed below a flange (21), the cover (20) having a second tube body (23) and a male screw (24), and includes a packing closure (30) having a third tube body (32), a fourth tube body (33), a female screw (34), and a packing (36) which has elasticity and which is disposed inside the body (31). The first tube body (22) is fitted and assembled to the branch tube (13), and medication is capable of being injected inside the T-tube (10) with a syringe by piercing the packing (36) with a syringe needle and passing the syringe needle through the third tube body (32).

A nasal inhaler for use in a nebulizer system for prolonged and continuous administration of medications. The inhaler includes an interface tube configured for connection to a nebulizer chamber, an outlet tube, and a patient interface assembly. The inhaler interface includes a hollow interface coupler having a connector tube for coupling to the interface tube, a hollow removable concentrator connected to the interface coupler and having two concentrator outlet tubes, and two nares elements, one each removably connected to one of the concentrator outlet tubes. The interface coupler and the concentrator form a plenum through which medicated air under positive pressure from the nebulizer travels through the nares elements to a patient's nostrils.

A ventilation control unit (100), regulating a gas flow (102) within a ventilation system (105), includes a reception module (120), first and second calculation modules (130, 135) and an output module (140). The reception module has a signal interface (122) receiving inspiratory and expiratory flow signals (125, 127) at regular time intervals. The first calculation module calculates a leak flow (132) based on a difference between the current inspiratory gas flow and the current expiratory gas flow, with an external gas flow source (110) separated from a ventilation circuit of the ventilation system. The second calculation module calculates an external gas flow (136) after connecting the external gas flow source to the ventilation circuit based on the leak flow and the difference between the current inspiratory gas flow and the current expiratory gas flow. The output module outputs an output signal (142), based on the external gas flow.

An inline adapter is provided including an elongated hollow body having an open first end configured to be connected to an inspiratory port of a patient ventilation assembly, an open second end opposite the first end, and a sidewall extending therebetween defining an airflow channel. The adapter also includes an inhaler port extending from the open second end of the adapter body configured to be connected to an inhaler, and an inspiratory branch having an open first end extending from an opening in the sidewall of the adapter body and an open second end configured to be connected to an inspiratory limb of the ventilation assembly. A longitudinal central axis of the inspiratory branch is angled relative to a longitudinal central axis of the adapter body.

The invention provides compositions, kits and methods for depositing a composition comprising a plurality of magnetic particles, to a target site of a subject by delivering the composition via controlled inhalation to a region of the subject's respiratory tract and applying a magnetic field to a target site within the region of the subject's respiratory tract to capture the particles in said target site.
