Description

Description of the invention

The subject of the invention is a device for disinfecting body fluids, intended primarily for use in medicine. The germs of infectious diseases are mainly transmitted through blood and lymph, and the device according to the invention can be used to disinfect these fluids. As a result, it will be possible to treat infectious diseases caused by bacteria, viruses, fungi and other microorganisms. Microbes cause many diseases that, if left untreated, can lead to the death of living creatures. Combating them is burdensome and the effectiveness of the currently used preparations is diminishing. Due to their great variability, microorganisms become resistant to any drugs, creating new, mutated populations resistant to previously effective preparations.

A germicidal cylinder for sterilizing liquids by means of ultraviolet radiation is known from the patent specification 151 251. The essence of the known invention consists in the fact that the device for sterilizing liquids by means of ultraviolet radiation is an irradiation chamber in the shape of a one-sided closed cylinder with an ultraviolet radiation sensor connector in the middle of the chamber height and an inflow connector with a test valve and an outflow connector with a temperature sensor and a test valve, and with the nozzle of increased liquid flow. The illumination chamber is closed on one side with a cap with a terminal strip and a sealing ring of the lamp mounted in the socket in the lower part of the illumination chamber. The ultraviolet radiation sensor is a current-voltage converter with a photodiode and an optical filter, the converter cooperating with a threshold circuit of the lamp's emission capability system. The lamp ignition system is connected with the mains voltage failure control system equipped with a stabilistor diode with low dynamic resistance.

The known solution uses only ultraviolet radiation. On the other hand, X-rays, cathode rays or ultrasound can play a special role in the inactivation of microorganisms in body fluids.

The device according to the invention consists of a housing inside which there is a pump forcing the flow of body fluids in the transfer line and for directing the body fluid into the spiral. The spiral is located in the irradiation chamber, which is also equipped with at least one radiation source, which is an ultraviolet lamp and / or an ultrasound generator and / or an ionizing radiation source. In addition, the device is equipped with a control panel that regulates the speed of the body fluid flow, the radiation intensity or the frequency of the ultrasound wave, and measures the temperature in the irradiation chamber. Additionally, the device is equipped with a microfilter that separates high-molecular structures of the body fluid. The spiral located in the irradiation chamber is made of a material that allows penetration of the applied type of radiation or ultrasonic waves.

The device according to the invention is shown schematically in the drawing in an exemplary embodiment.

The device consists of an irradiation chamber 1, which is equipped with at least one X-ray source or 2, and the power of the irradiation source is at least 10 grams Mev. The body fluid of a sick individual is fed through the transmission line 3 to the irradiation chamber 1. The circulation of the fluid is forced by the pump 4, which directs the fluid to the spiral 5 made of plastic in the chamber 1. The fluid flowing inside the spiral 5 has no contact with the external environment and is exposed to ionizing radiation with a dose of not more than 50 kGy for a time not longer than 10 seconds. After leaving the irradiation chamber, the fluid to be irradiated is reintroduced into the vessels of the treated subject. The control panel 6 used in the chamber enables the regulation of the flow rate of the body fluid, the intensity of radiation and the temperature in the irradiation chamber 1. Complete decontamination of human body fluids takes about 0.5 hours and the decontamination efficiency is 100%.

Additionally, the device can be equipped with a microfilter 7 which separates the macromolecular structures of the body fluid. Low molecular weight elements and plasma fluids are directed to the irradiation chamber 1, while the age-molecular structures of body fluids are led outside the irradiation chamber 1.

X-rays and cathode rays can play a special role in the inactivation of microorganisms in body fluids. Their use is supported by the fact that they selectively eliminate organisms that contain DNA and RNA, without damaging other structures of living organisms. In the case of blood, they can be used without major restrictions, because the risk

The formation of harmful substances during irradiation is low. Also, a high chance of inactivation of microorganisms is expected to be obtained with the use of ultrasound. They can selectively destroy selected microorganisms without harming the components of body fluids. The possibility of using these waves is related to the fact that the components of body fluids have different sizes, and their decomposition under the influence of the applied waves occurs unevenly. Decontamination with the use of UV radiation shows high efficiency in the fight against bacteria, viruses and spores of these organisms. This radiation is known to be harmful to protein structures, hence there is a chance that it will be highly effective in combating HIV.
