  • Patent number: 6561186
    Abstract: An inhalation-activated inhalator having a primary inhalation passage and a secondary inhalation passage disposed in communication with the primary inhalation passage and a source of medicament. The primary inhalation passage has airflow inhibiting mechanism connected to a blocking plate positioned to selectively block fluid flow in the secondary inhalation passage. As the user's inhalation reaches a defined rate, the flow inhibiting mechanism restricts flow through the primary inhalation passage and moves the blocking plate to enable airflow through the secondary passage. Thus, as the user achieves a desired inhalation rate, the medicament is provided through the secondary inhalation passage, thereby optimizing the delivery of medicament to the lungs.
    Type: Grant

  • Patent number: 5577837
    Abstract: A console shaker which includes a shaker device mounted within a temperature and lighting controlled chamber and an air jacket which completely surrounds the chamber and also provides substantially laminar, HEPA-filtered air flow through the chamber in one direction. A refrigeration device and a heating device either cool or heat the air before it flows through the HEPA filter. The HEPA filter is mounted at the end of the chamber which defines an air inlet to the work chamber and an outlet is disposed at the opposite end of the chamber. The outlet end of the chamber receives air from both within the workspace of the chamber as well as from the front and rear air spaces of the air jacket. A microprocessor based control system provides an interface between the user and the various components for establishing the conditions within the chamber, such as shaker speed, temperature, time and lighting to be controlled by the user.
