Description

Technology area

The present invention relates to a hemodialysis machine.

Conventional technology

The method of dialysis treatment for blood has already been widely used for the treatment of the pathology of acute or chronic weakening of kidney function. Specifically, by introducing the patient's blood into the dialyzer and using the difference in the concentration of solutes on both sides of the semi-permeable membrane, through osmosis, diffusion, filtration, etc., the metabolic products and toxic substances The substance is wiped out and the imbalance between water and electrolyte is corrected. This is the so-called “artificial kidney”.

However, an “artificial kidney” is still not a kidney but can fulfill the function of a human kidney to some extent, but cannot be completely replaced. In addition, when the “artificial kidney” is used for a long time, many complications may occur. For example, when hemodialysis is performed using current hemodialyzers, there is a risk that renal anemia will always be strengthened, cardiovascular complications will be induced, and the remaining kidney function will be accelerated. . In addition, the “artificial kidney” has a function of filtering blood, but cannot treat cardiovascular complications or anemia caused by kidney weakness or hemodialysis. Therefore, in the case of patients who have undergone long-term hemodialysis, the actual problem is that the mortality rate due to cardiovascular disease is higher than the mortality rate due to the weakness of kidney function itself.

In contrast, irradiation has already been used as a therapeutic method in a wide range. Among them, red light treatment promotes repair and fusion of the affected area, enhances cell function, clears free radicals, delays skin aging, enhances cosmetic effects, and increases blood viscosity. It has functions such as lowering, remarkably increasing the oxygen carrying capacity of blood, and regulating the efficacy of immunity. In addition, ultraviolet rays and the like have strong photobiological effects and functions such as sterilization, and blue light and light in other frequency ranges also have therapeutic functions.

Contents of device

The purpose of the present invention is that a conventional hemodialysis machine can perform only a partial function of the kidney, which eliminates metabolic products and toxic substances by performing dialysis on the blood of the patient. To provide a new hemodialysis machine that can solve the technical problem that anemia and cardiovascular complications due to dialysis cannot be treated, and that the remaining kidney function cannot be maintained and repaired. That is.

The technical contents of the present invention are as follows. That is, the device of the present invention is a hemodialysis machine, which includes a dialyzer for blood purification, a dialysis fluid supply and circulation system, an extracorporeal blood circulation system, and prevention and treatment of cardiovascular diseases. Has a phototherapy device for blood used to alleviate the pathology of anemia and maintain and restore the function of the remaining kidneys, etc., and to the blood in the extracorporeal blood circulation system by the light emitted by the light source Irradiation treatment is performed.

The extracorporeal blood circulation system has an arterial blood circuit led out from a patient's artery, and a venous blood circuit that sends blood that has been filtered by a dialyzer to a patient's vein. Irradiation can be performed in any one of the venous blood circuit and the arterial blood circuit and the venous blood circuit.

The light source of the blood phototherapy device can be any light-emitting device that mainly satisfies conditions such as the frequency of light and the efficiency of light. For example, it can be selected from light sources such as light emitting diodes, white photoelectric lamps, fluorescent lamps, or laser launchers.

The light source of the blood phototherapy device generates light having a frequency of 500-850 nanometers. It has already been proven from long-term clinical experiments that light with a frequency of 500-850 nanometers has the most positive effect on the human body and is most easily absorbed by the body. In general, it does not cause harm to the body unless the irradiation with light is excessive. Therefore, it can be said to be a safe physical treatment method.

The light source can be placed around the blood circuit to meet the requirements of illumination intensity. The blood circuit can be arranged around the light source, or the light source can be arranged directly in the blood circuit.

The blood phototherapy device may have an annular outer cover, the light source may be disposed on a ring provided inside the cover, and the blood circuit may be provided so as to penetrate the inner ring.

By adopting the light irradiation treatment method of the above technical idea, it is possible to increase the secretion amount of EPO inside the patient's body and alleviate the pathology of the anemia. Light irradiation reduces the incidence of cardiovascular disease through controlling oxidative stress and scavenging free radicals. Also, light irradiation can play a role in protecting and repairing the function of the remaining kidneys of the patient undergoing dialysis treatment at the same time. When blood flows through the extracorporeal blood circulation system, it can be treated for anemia caused by hemodialysis and cardiovascular complications by receiving light emitted from the blood phototherapy device. Technical problems that the hemodialysis machine can only treat blood, cannot treat hemodialysis anemia and cardiovascular complications, nor can it retain and repair the remaining kidney function Can be solved. Further, the outer cover has an annular structure, and a light emitting diode or laser emitting device is installed inside the annular outer cover as a red light source, so that the focus of light emitted from the red light source flows through the blood. The dose of light to the blood can be greatly increased so as to match the tube.

Specific implementation method Example 1
As shown in FIG. 1, a hemodialysis machine of the present invention includes a dialyzer 1 for blood purification, a dialysis fluid supply and circulation system 2, an extracorporeal blood circulation system 3, and a cardiovascular disease. It has a blood phototherapy device used for prevention and treatment, relief of anemia conditions, and the like. The light emitted from the light source 7 of the phototherapy device performs irradiation treatment on the blood in the blood circulation system 3 outside the body. The extracorporeal blood circulation system 3 includes an arterial blood circuit 4 derived from a patient's artery, and a venous blood circuit 5 for sending blood that has been filtered through a dialyzer to a patient's vein. Irradiation can be performed in one of the circuit 4 and the venous blood circuit 5, or both the arterial blood circuit 4 and the venous blood circuit 5 can be irradiated simultaneously.

The light source 7 of the blood phototherapy device can be selected from a light emitting diode, a white photoelectric lamp, a fluorescent lamp, or a laser emitting device. The frequency of the light is 500-850 nanometers. The light source 7 can be disposed around the blood circuit. Alternatively, the blood circuit may be disposed around the light source, or the light source 7 may be disposed directly in the blood circuit. Further, the light source and the blood circuit may be crossed with each other.

In addition, the blood phototherapy device is designed to have a structure that forms an annular outer cover 6, the light source 7 is disposed on a ring provided inside the annular cover, and the blood circuit is connected to the inner ring. It can be placed on the body axis.

The treatment of light irradiation can be performed at any stage of the blood circulation process. That is, it can be performed in the process of blood circulation in the patient's body or in the process of blood circulation outside the body. However, in consideration of the degree of pain caused to the patient by light irradiation in the body, the risk of injury and infection, etc., it is desirable to adopt a safe method mainly of light irradiation to blood outside the body.

Also, the blood phototherapy device can be installed in a hemodialysis machine, or it can be provided as an independent device and used in combination with another existing dialysis machine. Even in the latter case, the same therapeutic effect can be achieved.

FIG. 1 is a conceptual diagram showing the structure of the present invention.
