Abstract
A device (60) for irradiating blood is provided, the device including a chamber (62) having an elongate configuration defining a hollow interior, the chamber formed of reflective material, a tubular cassette (74) sized and shaped to be received in the interior (70) of the chamber, the tubular cassette (74) having an inside diameter sized and shaped to receive a reflective core (78) having an elongate configuration with an exterior diameter smaller than the interior diameter of the cassette to provide a space (75) for receiving and holding blood stationary, and an array of light-emitting members (80) arranged on the chamber for emitting light of at least one wavelength into the interior (70) of the chamber (62) for irradiating and treating the blood inside the cassette (74).
Claims19
A device for subjecting a patient's blood to light for the purpose of altering the immune function of the patient, the device comprising:
- a chamber having a window formed of a quartz plate;
- a back attached to the chamber and formed of hard plastic, the back having an inlet port that communicates with the chamber, including a stopcock valve adjacent the outlet port to retain a stationary quantity of blood in the chamber and to selectively permit the entry of fluids into the chamber when treated blood exits the chamber back to the patient via the inlet port;
- and
- a housing for directing light from a light source to the chamber.
A method of treating blood from a patient, comprising:
- a. receiving blood intravenously from a patient at an inlet port of a chamber by force of the intravenous blood pressure;
- b. filling the chamber with the patient's blood from the inlet port at the bottom of the chamber to a valve at an outlet port at the top of the chamber;
- c. exposing the blood in the chamber to a light source as the blood is held stationary for the purpose of altering the immune function of the blood of the patient;
- d. opening the valve at the outlet port to introduce fluids into the chamber through the outlet port with sufficient force to return the blood back to the patient intravenously and flushing the chamber with the fluid;
- and
- repeating steps a through d.
A device for irradiating blood, comprising:
- a chamber having an elongate configuration defining a hollow interior, the chamber having an opening to provide access to the chamber and a cover to close the opening;
- a tubular cassette sized and shaped to have an elongate configuration and to be received in the interior of the chamber, the cassette having an inside diameter sized and shaped to receive a reflective core having an elongate configuration of an exterior diameter that is smaller than the interior diameter of the cassette to provide a space for receiving and holding blood stationary;
- and
- an array of light-emitting members arranged on the chamber for emitting light of at least one wavelength into the interior of the chamber for irradiating and treating the blood inside the cassette.
A device for irradiating a predetermined stationary quantity of a patient's blood, comprising:
- an outer wall enclosing an interior;
- a container configured to hold the predetermined quantity of blood stationary in the interior of the outer wall;
- and
- a light source for emitting light onto the blood to irradiate the blood.
A device for treating fluids, comprising
- a chamber formed by an outer wall having an inside reflective surface;
- a reflective core positioned inside the outer wall;
- an intermediate wall positioned between the outer wall and the reflective core and configured to form a fluid container to hold a predetermined quantity of fluid stationary;
- and
- at least one light-emitting device configured to emit light through the intermediate wall for irradiating fluid in the fluid container.
A method for treating fluid, comprising:
- placing fluid inside a container formed by a reflective core and a circumscribing quartz wall defining a space between the circumscribing wall and the core for retaining the fluid in a stationary condition;
- placing the container inside a chamber formed by an outer wall having reflective characteristics;
- and
- exposing the container and the fluid to light to treat the fluid as the fluid is held stationary inside the container.
