Definitions
- the invention relates to a method and a device for inactivating viruses and / or bacteria in liquid media, in particular in blood plasmas and serum conserves according to the preamble of the independent claims.
- the mechanism of this inactivation is based on the interaction of methylene blue with the viral genome and subsequent irradiation with sodium (D) light.
- methylene blue is mutagenic, the reagent must be completely separated after inactivation of single plasmas.
- the inactivation with methylene blue is basically suitable for all viruses. In practice, however, it has been shown that some unencapsulated viruses can not be inactivated, especially the small porcine parvovirus (PPV).
- PSV small porcine parvovirus
- chemical methods such as the use of psoralens, eg amotosalen and radiation are known.
- the medium is irradiated with such a frequency and power density of the ultrasound that hard cavitation occurs, in which cavitation bubbles generated in the medium implode, so that shock waves are generated which inactivate the viruses and / or bacteria.
- the threshold at which hard cavitation occurs is, for example, for blood plasma at about 1 W / cm 2, preferably at frequencies between 27 kHz and 40 kHz. These numbers are exemplary ⁇ ; higher power densities for inactivating the viruses and / or bacteria from about 2.5 W / cm 2 to about 6 W / cm 2 and more are possible.
- An advantage of the method according to the invention is also that in the preferably used hard cavitation enveloped and non-enveloped viruses and / or bacteria are inactivated, wherein the inactivation is supported in particular by small viruses by the additional UV irradiation.
- An apparatus for carrying out the method according to the invention initially has a chamber, in particular a pressure chamber for receiving containers filled with blood plasma or a serum from a gas, but no liquid passing material, wherein the chamber has valves to a protective gas, in particular Introduce CO 2 in the pressure chamber.
- the protective gas diffuses through the walls of the container into the medium. Other residual gases, in particular oxygen, are thereby removed from the containers and from the chamber.
- the apparatus further comprises at least one ultrasound source for irradiating the containers with ultrasound.
- an ultrasonic bath with a liquid, in particular water receiving basin and at least one ⁇ radiating into the liquid of the ultrasonic bath ultrasonic transmitter provided.
- the vessel is designed so that essentially the same power density is registered at all points. It may have ⁇ it to be useful to use in cross section circular vessels.
- At least one light source emitting ultraviolet light is additionally provided for irradiating the container receiving the medium.
- the wavelengths of UV light lie between 50 nm and 400 nm, in particular between 250 nm and 320 nm.
- Figure 2 shows a cross section through an ultrasonic bath with a plurality of ultrasound transmitters, are received in the blood bag, in addition, a plurality of UV light sources are provided to irradiate the blood bag with UV light.
- a pressure chamber 1 is shown schematically, which has a gas inlet 2 and a gas outlet 3, which open in each case with a valve 4 and 5 respectively Bezie ⁇ hung as pressure-tight manner can be closed.
- the pressure chamber can through one or more partitions 9 to increase the number of blood bags accordingly.
- the blood bags 6, which hold between 50 ml and 10,000 ml of blood plasma 7, are made of a material that is permeable to gas but does not allow fluid to pass through. In addition, this material is also permeable to ultraviolet light (UV light).
- UV light ultraviolet light
- a protective gas in particular CO 2 or NO 2 (laughing gas)
- CO 2 or NO 2 insect gas
- the pressure in the pressure chamber 1 was set to 10 bar, but pressures between 5 and 25 bar are also suitable.
- the valve 4 was shut off in the gas inlet 2.
- the pressure in the pressure chamber 1 was kept constant at the elevated pressure value of 10 bar for 60 minutes to 150 minutes. It was found that after this period of time, the oxygen previously contained in the blood plasma 7 was completely displaced by the inert gas that had diffused into the blood bag and the blood plasma was saturated with the protective gas.
- control means 17 is provided, with which the functions of the piezo ⁇ electric vibrator 15 and the UV light sources 16 is controlled.
- the piezoelectric oscillator 15 and the UV light sources 16 can be operated continuously or discontinuously, wherein preferably the ultrasound irradiation and the UV light irradiation take place simultaneously.
- the treatment with ultrasound and UV light can take up to five hours.
