United States Patent 7,143,908: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
The United States Patent 7,143,908, titled "Indicating Device," is a significant innovation in the field of medicament dispensing devices. This patent, granted to inventors associated with pharmaceutical and medical device companies, addresses the need for accurate and reliable dose indication in inhalation devices.
Background and Context
Medicament dispensing devices, particularly those used for inhalation therapy, require precise mechanisms to indicate the number of doses dispensed. This ensures patient compliance and safety. The patent in question builds upon earlier innovations in dose counting and indicator mechanisms.
Scope of the Patent
Device Overview
The patent describes a device for dispensing metered dosages of a substance from a container. The device includes a dispenser housing with a longitudinally extending cavity, a container that moves reciprocally within the housing, and an indicator assembly[4].
Key Components
- Dispenser Housing: The housing supports the container and includes a well to receive the valve stem and an exhaust port for dispensing the substance.
- Container: A cylindrical canister with a hub and a valve stem extending from it.
- Indicator Assembly: This includes a worm, circular gear, and indicator members that display dosage indicia visible to the user.
Claims of the Patent
The patent includes several claims that define the scope of the invention:
Mechanism of Operation
- The device operates by moving the valve stem to the open position, which dispenses a metered dosage through the exhaust port.
- The reciprocal movement of the container causes the worm to rotate, which in turn rotates the circular gear and advances the indicator member to display the dosage indicia[4].
Indicator Assembly Details
- The indicator assembly includes a ratchet wheel, worm, actuator member, and indicator member, all mounted within an indicator module.
- The actuator member engages the teeth on the first indicator member to advance it incrementally in response to the container's movement[4].
Advantages and Features
- The device ensures accurate and reliable dose indication.
- The indicator module is a self-contained unit that can be separately manufactured and installed in various dispensing devices with minimal modification.
- The parts are relatively inexpensive to manufacture and assemble, and the indicia are easy to read and accessible to the user[4].
