United States Patent 9,463,288: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
The United States Patent 9,463,288, titled "Dry powder inhalation apparatus," is a significant innovation in the field of medical devices, particularly for the delivery of medicaments. This patent, granted to its inventors, outlines a sophisticated design for an inhalation apparatus that enhances the efficacy and user experience of dry powder inhalers.
Background
Dry powder inhalers are crucial for patients with respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). The effectiveness of these devices hinges on their ability to deliver the medicament accurately and consistently. The US Patent 9,463,288 addresses several challenges associated with traditional dry powder inhalers, such as inconsistent dosing and user difficulty in operating the device.
Scope of the Patent
Overview
The patent describes a dry powder inhalation apparatus that is operable by the breath of the user. This design ensures controlled and smooth transfer of the medicament during multiple actuations, enhancing the overall efficiency of the device[1].
Key Components
- Delivery Channel: The apparatus includes a delivery channel through which the medicament is dispensed. This channel is designed to optimize the flow of powder, ensuring consistent dosing.
- Reservoir: The device features a reservoir that stores the dry powder medicament. The reservoir is engineered to maintain the integrity of the powder until it is dispensed.
- Ratchet Mechanism: A ratchet mechanism is incorporated to ensure that the device can be actuated multiple times without the need for manual resetting. This mechanism helps in maintaining a consistent dose delivery.
- Abutment: The abutment is a critical component that interacts with the ratchet to control the movement and actuation of the device.
Claims of the Patent
The patent includes several claims that define the scope of the invention. Here are some key claims:
Independent Claims
- Claim 1 describes the dry powder inhalation apparatus with a delivery channel, a reservoir, and a ratchet mechanism.
- Claim 2 specifies the interaction between the ratchet mechanism and the abutment, ensuring controlled actuation.
Dependent Claims
- These claims further detail the specific features and functionalities of the components mentioned in the independent claims. For example, Claim 3 describes the design of the delivery channel to optimize powder flow.
Patent Landscape
