Abstract
The apparatus and method for detecting blood in urine or feces includes a photodetector configured to detect a transient light emitted in a toilet bowl by luminol and an oxidizer catalyzed by iron in the blood. The apparatus may include dispensers for the luminol, the oxidizer and a base. The apparatus may include a microprocessor and a network connection and may perform statistical analyzes, store data and alert the patient or a healthcare provider if blood is detected. The photodetector may be configured to detect light emitted in the toilet bowl by a fluorophore present in the water and excited by the transient light from the luminol and oxidizer.
Claims47
An apparatus for detecting blood in urine or on feces, the apparatus comprising:
- a photodetector, said photodetector being configured to detect a light emitted by a reaction of a luminol and an oxidizer catalyzed by an iron in a water in a toilet bowl, said photodetector being located proximate to said water in said toilet bowl but not submerged within said water in said toilet bowl, whereby said photodetector is configured to detect said iron from a heme in the blood when the blood is present in the water in the toilet bowl along with said luminol and said oxidizer under alkaline conditions.
An apparatus for detecting blood in urine or feces, the apparatus comprising:
- a. a toilet having a toilet bowl containing a water,
- b. a photodetector, said photodetector being configured to detect a light emitted by a reaction of a luminol and an oxidizer catalyzed by an iron in said water in said toilet bowl, said photodetector being located proximate to said water in said toilet bowl but not submerged within said water in said toilet bowl, whereby said photodetector is configured to detect an iron from a heme in the blood when the blood is present in the water in the toilet bowl along with said luminol and said oxidizer under alkaline conditions.
A method of providing an apparatus for detecting blood in urine or feces in a water in a toilet bowl, the method comprising:
- a. providing a photodetector, said photodetector being configured to detect a light emitted in the water in the toilet bowl by a reaction of a luminol and an oxidizer and catalyzed by an iron present in the blood in the water in the toilet bowl when said photodetector is located proximate to said water in said toilet bowl but not submerged within the water in the toilet bowl and blood is present in the water in the toilet bowl under adequately alkaline conditions;
- b. providing an instruction, said instruction instructing a user to:
- i. add said luminol and said oxidizer to said water;
- ii. add the urine or feces to the water after adding said luminol and said oxidizer to said water.
A method of testing urine or feces in a water in a toilet bowl for a presence of blood, the method comprising:
- a. receiving by a user of a photodetector, said photodetector being configured to detect a light emitted in the water in the toilet bowl by a reaction of a luminol and an oxidizer and catalyzed by an iron present in the blood in the water in the toilet bowl when blood is present in the water in the toilet bowl;
- b. locating said photodetector proximate to the water in the toilet bowl but not submerged within the water in the toilet bowl;
- c. adding said luminol and said oxidizer to the water;
- d. adding the urine or feces to the water after adding said luminol and said oxidizer to the water;
- e. detecting by said photodetector of whether said light is emitted in the water of the toilet bowl.
