Description

The present invention relates to a compact design for a device used with inhaled medicines and, more specifically, a reliable compact design for a dry power inhaler (DPI).


BACKGROUND

It has been a very potent and effective medication (powder form) to treat Asthma and Chronic Obstructive Pulmonary Disease (COPD). However, currently available delivery devices are not effectively spread medication to most peripheral part of the airway system in the lung, where medication effects are needed. Moreover, these devices are ugly, making patients uncomfortable to use, and mouthpieces are generally not a perfect fit to inhale all amounts of medication to deliver to the intended part of the lung.


Therefore, a need exists to develop a system and method to effectively deliver inhalation mediation to a patient of needed. A cigarette shaped device may be easy to use, convenient and even available to use in public places without being noticed by the surrounding with compliance rate increased and medication reached to most peripheral parts of the lung more effectively are desired. The device may provide not only a mouthpiece perfect fit for every user, in using medication mimic smoking, but also a patient can use medication in public compliance rate higher. Effectively sucking, even repeatedly until all single power medication is inhaled and more precise delivery of medication can be achieved.


A design as a cigarette may also stimulate suction and lips easily adapt mouthpiece of cigarette and instantly synchronize suction of powder medication, if one puff is not enough to empty all medication, a patient can repeat several puff until last powder of medication sucked in and more effective delivery results in style.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.


As will be appreciated by one of skill in the art in view of this disclosure, the present invention may be embodied as a device or method to effectively deliver inhalation mediation to a patient. Thus, as described in more detail below, embodiments of the present invention provide for components of the device and specific mechanisms invented to implement the device in the intended purpose.


Turning now to the figures, FIG. 1 illustrates a general layout 100 of the compact inhalation device (CID) including a mouth piece (A), drug chamber (B) and air flow chamber (C), in accordance with embodiments of the present invention. The device is implemented with a drug chamber open/close mechanism (AB) between the mouth piece (A) and the drug chamber (B), as well as an air flow chamber open/close mechanism (BC) between the drug chamber (B) and the air flow chamber (C).


The CID is designed as a tube-shaped device similar to a regular cigarette, for example elongated cylindrical body, made with recycled or reusable materials. The recycled or reusable materials comprise one or combination of paper, meshed paper, meshed reinforced paper, thin plastic, hard rubber, aluminum, thin glass or carbon fiber. The mouth piece, drug chamber and airflow chamber are separable components attachable with an arrangement shown in FIG. 1.


The mouth piece is a part which one end fits by a patient's mouth when use to suck medication and the other end is connected to the medication chamber. The medication (e.g., the drug powder) will flow into the mouth through the mouth piece when the patient start using it. The medication chamber stores measured amount of medication powder to be used. The medication chamber releases medication just prior to inhaling by a user in a mechanism by twisting at connection with adjacent part or one-way valve to a direction to a patient who start giving suction force. The airflow chamber is a top or far end of the CID allowing air from environment to push medication into the patient's mouth through the medication chamber and the mouthpiece.


Referring to FIGS. 2a and 2b, the figures describe one way valve mechanism for a close and open positions of the joint between the mouth piece and the drug chamber. FIG. 2a shows that the one-way valve is in close or normal position 201 when the one-way valve is closed using a valve stop. Moreover, FIG. 2b depicts a flap of the one-way valve is in open position to allow the flow of the medication and/or air flow from the drug chamber B to the mouth of the user/patient via the mouth piece A.



FIGS. 3a-3c depict the twisted close/open mechanism appearing at the joint between the mouth piece and the drug chamber. The mouth piece A and the drug chamber B are coupled with a joint or interfaces providing air tight connection but are capable of being twisted. Each interface of the mouth piece and the drug chamber have an opening, which is aligned each other to provide an opened drug chamber position 303 and is unaligned each other to block a flow of the drug form the drug chamber as in the closed drug chamber position 302.


Referring to FIGS. 4a and 4b, the CID is implemented the flapped flow close/open mechanism both at the connection or interfaces (AB) between the mouth piece A and the drug chamber B, and at the connection or interfaces (BC) between the drug chamber B and the air flow chamber C. The FIG. 4a shows the positions of the one-way valves closing with valve stops for the all valve closed condition and the FIG. 4b shows the positions of the flaps of the one-way valves for in use or open condition.


Referring to FIGS. 5a and 5b, the figures depict mixed or combined use of the twisted close/open mechanism and the flapped flow close/open mechanism in a CID. Either one of the interfaces AB and BC can be implemented with the twisted close/open mechanism or the flapped flow close/open mechanism as a choice of the implementation of the device.


Referring to FIGS. 6a-6d, the figures show a measured amount of drug in separate tubes for a plurality of doses and open/close mechanisms, which can be implemented to release medication powder of the tubes. The drug chamber contains a small tube for a measured amount of the dry powder medication for a dose, or seven small tubes of the dry powder medication for seven days or seven doses (see FIG. 6a). The openings for the seven small tubes can have the twisted close/open mechanism using a circular, triangle, square or rectangle shape of the opening.


Additionally, FIG. 7 illustrates an insertable medication chamber for a different implementation of the CID. The insertable medication chamber can be insert into a slot of a base body, which acts the purpose of the mouth piece and the air flow chamber described above. As an advantage, the insertable medication chamber can be replaced after used and the reusable base body may be made in customized design, shape or material.


Those skilled in the art may appreciate that various adaptations and modifications of the just described embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
