A respiratory system drug applicator for a patient is disclosed which may include a number of features to enhance the administration of the aerosolized drug to the patient. For instance, an adjustable flow regulator may be utilized which regulates the air flow during inhalation by the patient (during which the aerosolized drug is also administered to the patient's respiratory system), and thus affects the patient's breathing pattern. Moreover, a distensible drug reservoir which changes shape during inhalation and exhalation by the patient may be utilized. This may be used to provide biofeedback to the patient regarding the patient's breathing pattern.
An inhalation device has a container 2 for an aerosol volume inhaled via a channel 15 and a mouthpiece 14, the container being located within a housing 12. The aerosol, in particular vitamin A, is introduced from a cartridge 17 into the interior of the container 2 via a nebulizer 18. The breath flow in the inhalation device is controlled via a control means 5 that keeps the inhalation flow essentially constant during the entire inhalation period.
This invention relates to an apparatus for inducing a pediatric patient breathing gas through a face mask to inhale a fluid pharmacological agent. The apparatus comprises a fluid conduit through which fluid pharmacological agent may be inhaled, and a sensory patient stimulator coupled to said conduit and accuatable by inspiratory or expiratory flow through said conduit.

A medication introducing device for airtight connection between a bag-valve mask apparatus, or other similar pre-hospital emergency respiratory device, and an endo-tracheal tube installed in a patient, the device comprising a central housing having a top opening, a bottom opening, and a minimum of two medication administering ports, at least one of the ports being an injection port for emergency administering of medications through pre-filled syringes into patients for which an intravenous line cannot be established, medications such as cardiac medications including atropine, epinephrine, lidocaine, and narcan, and at least one port being a nebulizer port for administering asthma medications to an intubated patient undergoing pre-hospital emergency CPR. It is contemplated for the present invention to be made from chemically inert materials, to have a sufficiently low manufacturing cost so that it can be disposable, and for each port to have an airtight end cap. Applications may include, but are not limited to, pre-hospital emergency and rescue situations in which a bag-valve mask apparatus must be used on an intubated patient.
The use of a large ambulatory manual breathing unit in combination with a metered dose medication inhaler for delivering medication to a patient, who is either breathing spontaneously or non-spontaneously. The large bag or reservoir of the breathing unit is used to insure minimization of size and homogeneous disbursement of the particles of medication. For non-spontaneous patient breathing, the reservoir's contents are disbursed into the patient by manually or mechanically squeezing the bag, after which the bag returns to its original shape and volume. At one or the other end of the bag, a typical metered dose inhalator is mounted in a manner to disburse the medication into the bag, and directly in line therewith, through an adaptor. The metered dose inhaler collar, into which the inhaler fits, when the inhaler is not in use, is capped.
