Abstract
A blood irradiator for providing a uniform dose of X-ray beam irradiation for blood contained within a transfusion bag. A first X-ray tube is positioned to irradiate said bag from one side of the bag, and a second X-ray tube is positioned to irradiate said bag from the opposite side of said bag concurrently with said first bag whereby a uniform dose of X-rays is provided to the blood.
Claims10
An X-ray irradiator for providing a uniform dose of X-ray beam irradiation to blood in a transfusion bag, said irradiator comprising in combination,
- a) a chamber for mounting said transfusion bag;
- b) X-ray tubes mounted on opposed sides of said chamber;
- said tubes providing X-ray beams of radiation to said bag from opposite sides of said bag;
- and
- c) said tubes each providing radiation at a same selected energy level to said bag to thereby provide a total radiation energy to said bag which is substantially uniform throughout said bag.
An X-ray irradiator for providing a uniform dose of X-ray beam irradiation to a transfusion bag blood, said bag being in the form of a rectangular box-like container, said irradiator comprising in combination,
- a) source of X-ray radiation providing a beam of X-ray to cover a defined vertical area;
- and,
- b) means for positioning said bag with its thickness dimension perpendicular to said beam to permit said beam to irradiate a first surface of said bag;
- c) a support for said bag;
- and
- d) means for rotating said support to cause said beam to irradiate the surface of said bag opposite said first surface.
An X-ray irradiator for providing a uniform dose of X-ray beam irradiation to blood in a transfusion bag which bag is pliable and is contained in a cannister said irradiator comprising in combination,
- a) a chamber for receiving said cannister containing mounting said transfusion bag;
- b) first has X-ray tubes mounted to provide irradiation to opposite surfaces of said bag;
- c) the irradiation of said tubes effectively combining to provide uniform irradiation to the blood in said bag.
