Abstract
An osmolarity measuring system is configured to receive a contact lens in a measurement chamber. The measurement chamber includes a volume of fluid, and a series of electrodes are configured to measure the electrical properties of the fluid. A processing device correlates the measured electrical properties with an osmolarity measurement. Further, the processing device is configured to track trends in stored osmolarity measurements and alert the user to take an action, including the cessation or alteration of product use.
Claims76
An osmolarity measuring system, comprising:
- a measurement chamber configured to receive a volume of fluid and to receive a lens, the lens configured to carry a certain amount of tear film;
- a series of electrodes configured to measure the electrical properties of fluid in the measurement chamber;
- a processing device coupled to the series of electrodes, the processing device configured to detect a change in the electrical properties of the fluid in the measurement chamber when a lens is placed in the measurement chamber.
A test kit comprising:
- a set of contact lenses;
- and
- an osmolarity measuring system, the osmolarity system comprising:
- a measurement chamber configured to receive a volume of fluid and to receive a contact lens, the contact lens configured to carry a certain amount of tear film,
- a series of electrodes configured to measure the electrical properties of fluid in the measurement chamber, and
- a processing device coupled to the series of electrodes, the processing device configured to detect a change in the electrical properties of the fluid in the measurement chamber when a lens is placed in the measurement chamber.
A test kit comprising:
- a set of artificial tear solutions an osmolarity measuring system;
- and
- an osmolarity measuring system, the osmolarity system comprising:
- a measurement chamber configured to receive a volume of fluid and to receive a contact lens, the contact lens configured to carry a certain amount of tear film,
- a series of electrodes configured to measure the electrical properties of fluid in the measurement chamber, and
- a processing device coupled to the series of electrodes, the processing device configured to detect a change in the electrical properties of the fluid in the measurement chamber when a lens is placed in the measurement chamber.
A test kit comprising:
- a set of medications;
- an osmolarity measuring system, the osmolarity system comprising:
- a measurement chamber configured to receive a volume of fluid and to receive a contact lens, the contact lens configured to carry a certain amount of tear film,
- a series of electrodes configured to measure the electrical properties of fluid in the measurement chamber, and
- a processing device coupled to the series of electrodes, the processing device configured to detect a change in the electrical properties of the fluid in the measurement chamber when a lens is placed in the measurement chamber.
A method for configuring an osmolarity testing device comprising the steps of:
- determining a volume of a fluid to be used when testing osmolarity using the osmolarity testing device;
- measuring electrical properties associated with the determined fluid volume;
- establishing a baseline osmolarity value for the osmolarity testing device based on the measured electrical properties associated with the determined fluid volume;
- and
- providing a table that maps measured electrical properties to osmolarity values.
