This patent application is a non-provisional application claiming priority from U.S. Provisional Application Ser. No. 60/312,412, entitled “Hemo-Aide” filed on Aug. 15, 2001, and is fully incorporated herein by reference.
The present invention relates to the ultra violet irradiation of blood apparatus and, more particularly, to the modification of viruses and bacteria in the body without contamination using a unique method and cuvette apparatus.
In the past, others have attempted to eradicate viruses and bacteria using a mercury vapor lamp and an irradiation chamber. This combination, however, presented a number of problems. Since the mercury vapor lamp is made with contaminating materials, the irradiation chamber could become contaminated. As a result, this type of lamp has been restricted by the Federal Drug Administration from use in the treatment of fluids in this manner. Also, as the irradiation chamber is permanently secured to the unit, sterilization of the chamber is a very difficult, time consuming task.
In an attempt to overcome this problem, a number of patents have been issued that disclose apparatus and methods for the irradiation of blood or bodily fluids. As listed below in the order of issuance, these are:
Of these patents, the most relevant are: U.S. Pat. No. 5,770,147 to Muller entitled “Apparatus For The Irradiation of Body Fluids By Ultraviolet Light” (“Muller”); U.S. Pat. No. 5,429,594 to Castle entitled “Extra-Corporeal Blood Access, Sensing, and Radiation Methods And Apparatus” (“Castle”); U.S. Pat. No. 5,304,113 to Sieber entitled “Method of Eradicating Infectious Biological Contaminants” (“Sieber”); and U.S. Pat. No. 5,951,509 to Morris entitled “Blood Product Irradiation Device Incorporating Agitation” (“Morris”).
Muller ('147) discloses an apparatus for the irradiation of body fluids by ultraviolet light in a containment. In one embodiment, the containment consists of a cuvette, an adaptor, a drive motor, and a Ultraviolet lamp. The cuvette, upon being filled with blood removed from a patient, is fitted into the containment and engaged with the adaptor. The cuvette is then rotated by the drive motor and exposed to the Ultraviolet radiation uniformly. The cuvette also includes flow baffles to provide additional turbulence to generate a radial flow of the blood towards the Ultraviolet radiation. Upon completion of the radiation, the cuvette is disengaged from the containment, the irradiated blood is removed from the cuvette, and then returned to the patient.
Castle ('594) discloses a method and apparatus for extra corporeal access to blood for analysis and treatment of the blood. In use, the apparatus pumps blood from a patient through an outlet line and then returns the blood back to the patient through an inlet line. During this extra corporeal flow of the blood, the outlet line and the inlet line each have access ports in which the blood may be either analyzed or treated. Any treatment of the blood consists of energy or radiation and includes ultrasonic waves.
Sieber ('113) discloses a method to erradicate infectious biological contaminants such as the human immunodeficiency virus. The method consists of withdrawing the blood from a patient using a pump, adding anti-coagulants to the blood, an occluded vein sensor to prevent or inhibit the generation or existence of bubbles in the flow of the blood, inserting a photosensitizing agent, an irradiation chamber which consists of visible light to activate the photosensitive agent, and then returning the erradicated blood to the patient.
Morris ('509) discloses an apparatus for treating human blood by irradiation. In use, blood is withdrawn from a patient and supplemented by an anti-coagulant solution. The blood is then separated into two portions by a cell separator, such as a centrifuge, with one portion being directed into a bag for irradiation and another portion either being held in storage or returned to the patient. Upon a predetermined volume of blood accumulated into the bag, the bag is placed within an irradiation apparatus. The irradiation apparatus consists of an upper lamp array and a lower lamp array of ultraviolet individual lamps and the bag is placed in the middle of the upper lamp array and the lower lamp array to irradiate the blood prior to being returned to the patient.
The combination of the above patents reveals that there exist several ways to irradiate blood from a patient. Among the common disclosure of these patents is that blood is removed from a patient, the blood is irradiated using ultraviolet light to kill contaminants and viruses, and the irradiated blood is then returned to the patient. Each patent is distinguishable in that it introduces additional steps during this process and/or accomplishes the process in a different manner. However, none of the patents disclose or teach a closed system with the ability to remove contaminated blood from a patient in one channel, effectively irradiate the blood twice using the same cuvette, and then return the irradiated blood back to the patient using the same channel, thereby, providing an effective modification of the viruses and bacteria in the blood in an attempt to eradicate the same. Thus, there is a need and there has never been disclosed an apparatus and method that solves the problems presented by today's devices and is as effective as Applicant's unique invention.
It is the primary object of the present invention to modify viruses and bacteria in the body in an attempt to eradicate the same. A related object of the present invention is to effectively modify the viruses and bacteria using a minimal number of modalities or processes. Another related object of the present invention is to have a positive impact on the condition. A further related object of the present invention is to reduce the blood count or PCR within the body.
Another object of the invention is to provide an apparatus that uses pure safe ultraviolet light and that is calibrated to the required or desired frequencies. A related object of the invention is to use the ultraviolet light for the irradiation of the blood.
Another object of the invention is to eliminate the contamination through the use of personal cuvettes. A related object of the invention is to provide a cuvette which is smaller and more compact making it suitable as a portable unit for patients who are unable to attend or fulfill scheduled appointments at hospitals, outpatient health care clinics, etc . . .
Another object of the invention is to provide an apparatus and system that is inexpensive to manufacture. A related object of the invention is to provide a system that is safe and easy to use.
Other objects of the present invention will become more apparent to persons having ordinary skill in the art to which the present invention pertains from the following description taken in conjunction with the accompanying drawings.
The present invention is an apparatus and method for the modification of viruses and bacteria in the body. The apparatus consists of a cuvette, an irradiation station, a peristaltic pump, and a bottle which are all systematically situated with respect to a housing. A plurality of power control switches controls the operation of the apparatus. This includes an on/off power switch, an on/off pump control, and a ultraviolet light control switch. A timer is provided to regulate the time period the cuvette is exposed to the ultraviolet radiation within the irradiation station. A cover is provided to enable the cuvette to be used and exposed to ultraviolet radiation within an enclosed environment.
The Description of the Preferred Embodiment will be better understood with reference to the following figures:
Turning first to
The irradiation station 16 consists of a lens or faceplate 24 and brackets or sides 26. The faceplate 24 is a flat surface and is made of a quartz crystal material. The faceplate 24 has a width 28 (
In the preferred embodiment, the cuvette 32 is preferably made of a quartz crystal material and is placed within the irradiation station 16. Alternatively, it is contemplated that the cuvette 32 may be made of a durable plastic material. The cuvette 32 is preferably laid flat against the faceplate 24 and displaced evenly across the surface area of the faceplate 24. In this manner, the largest cross section of liquid or blood passing through the cuvette 32 is ultimately exposed to the ultraviolet light radiation. After the cuvette 32 is used for the treatment of fluid, the cuvette 32 can be disposed of and replaced with a new, unused cuvette 32. This effectively eliminates all chances of any kind of contamination in subsequent modalities or processes.
The pump 18 is preferably a peristaltic pump or the commonly referred to “paddle” pump. The pump 18 consists of a wheel 46 (
The plurality of power control switches 20 consists of an on/off power switch 36, an on/off pump control switch 38, and an ultraviolet light control switch 40. The on/off power switch 36 controls the electrical power of the blood irradiation apparatus 10. A power cord 42 (
The cover 14, during use and the modification process, is in the closed position to enclose the pump 18, the cuvette 32, and the irradiation station 16. The purpose of the cover 14 is to protect the attendant or others adjacent to the blood irradiation apparatus 10 from any harmful ultraviolet light radiation during the modality or process. The cover 14 contains apertures 44 which provide egress for the conduit 52 transporting the blood to and from the patient through the blood irradiation apparatus 10. When the cover 14 and/or the blood irradiation apparatus 10 are not being used, the cover 14 in placed in the open position to permit access to the pump 18 and the irradiation station 16 for purposes of servicing these components. For example, with the cover 14 in the open position, the cuvette 32 may be replaced within the irradiation station 16. The cover 14 is the means for enclosing the cuvette 32 and irradiation station 16 when the fluid or blood irradiation apparatus 10 is in use for minimizing the escape of ultraviolet light radiation.
In use, liquid or blood is withdrawn by venipuncture from the body through a conduit 52 and into an irradiation chamber or cuvette 32. Once within the cuvette 32, the liquid or blood is exposed to a controlled amount of ultraviolet light energy from the ultraviolet light source 56 within the radiation box 54 and through the faceplate 24. The amount of ultraviolet light energy is provided in the accepted therapeutic band in order to modify the virus or bacteria. The liquid or blood continues through to either the peristaltic pump 18 on the way to the bottle 34 or bypasses the peristaltic pump 18 and goes directly into the ivac bottle 34. The bottle 34 is the means for receiving the fluid transported and irradiated through the cuvette 32. If the liquid or blood is being transported from the body through the blood irradiation apparatus 10 by the pump 18, the liquid or blood will pass through the pump 18 in conduit 52 as it is the pump 18 which is artificially causing the transportation of the liquid or blood through the system. Alternatively, if the peristaltic pump 18 not being used, an ivac bottle 34 can be used as it provides its own vacuum to draw the blood from the body at a controlled rate. The peristaltic pump 18 or ivac bottle 34 is the means for drawing and transporting the fluid through the cuvette 32. This type of technique is also referred to as the Knott technique. Using the Knott technique, the liquid or blood will bypass the pump 18 and be transported directly into the bottle 34.
In the preferred embodiment, the amount of blood withdrawn from the body is approximately 1.5 cc of blood per pound of body weight with the total amount of blood per modality or process never exceeding 250 cc of blood. The reason is that if more than 250 cc of blood is removed from the body in one process, the blood remaining in the body would not be at an acceptable, healthy level for the patient. After the desired amount of blood is transported completely through the blood irradiation apparatus 10 and is contained within the bottle 34, the bottle 34 is then elevated into the air to a location above the blood irradiation apparatus 10. Once in this position, the bottle 34 is opened and the blood is permitted to drip from the bottle 34 to be transferred back through the blood irradiation apparatus 10 and returned to the body. Depending upon the amount of blood impacted and the desired retention time, the drip rate from the bottle 34 can be adjusted accordingly. The irradiated blood leaves the bottle 34 and returns through the cuvette 32 and the irradiation station 16 for a second time and is, once again, exposed or irradiated to a controlled amount of ultraviolet light energy from the ultraviolet light source 56 within the radiation box 54 and through the faceplate 24. The liquid or blood then continues back into the body through the same needle used for withdrawl. This entire process including the bottle 34 and the timer 22 is the means for returning the fluid back through the cuvette 32 from the bottle 34. This entire process is considered a single modality and is contained within a closed system that prohibits the introduction or potential for foreign objects or other contaminants to enter the system or adversely affect the procedure. An average procedure takes approximately one hour and patients can receive, at scheduled times, multiple procedures or as many procedures as it takes to positively impact the condition. The blood irradiation apparatus 10 is capable of modifying known viruses and bacterial diseases which includes but is not limited to septicemias, pneumonias, peritonitis, viral infections including acute and chronic hepatitis, atypical pneumonias, poliomyelitis, encephalitis, mumps, measles, mononucleosis, herpes. It is contemplated that the blood irradiation apparatus 10 has positive effects of the diseases known to man with little or no side effects. Although throughout this disclosure the term “blood” is used to designate the fluid passed through the apparatus, it is recognized that other body fluids can also be passed through the apparatus with the same results. Accordingly, the term “blood” is also meant to encompass any body fluids (i.e., human, animal, etc . . .) capable of being irradiated.
Thus, there has been provided a blood irradiation apparatus that effectively uses a closed system to modify viruses and bacteria in the body and provide a positive impact on the condition while further eliminating contamination from external sources. While the invention has been described in conjunction with a specific embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it in intended to embrace all such alternatives, modifications and variations as fall within the spirit and scope of the appended claims.
