SU770496A1 - Method of sterilizing biological tissues - Google Patents

Description

The invention relates to the field of medicine, namely to the sterilization of biological tissues.

There is a method of sterilizing biological tissues by treating them with ultrasound 5 [ΐ] ·

The disadvantage of this method is that sterilization of biological tissue is fully achieved only in a small number of cases and requires time.

At the same time, the nature of the objects to be sterilized (living biological tissues) imposes restrictions on a further increase in the intensive sounding and ultrasound treatment time of the tissues.

The aim of the invention is to increase the efficiency of ultrasonic treatment and thereby improve the quality of sterilization without increasing the intensity of ultrasound and the duration of treatment. At the same time, an increase in the efficiency of ultrasound should be achieved with full preservation of the biological properties of the tissue.

This goal is achieved by the fact that before ultrasound exposure to biological tissue .nanosyat

Thus, in the proposed method of sterilization of objects, the effect of ultrasound on biological tissues and microorganisms, enhanced by the action of particles on the surface and the microflora, is used. Moreover, when using the proposed method for the sterilization of living biological tissues, there are no negative reactions from the tissues, since after the cessation of the ultrasound exposure, the cells do not remain in the folds of the tissue and on its surface, but over time completely decompose. ? Kivi biological tissues at the same time fully retain their biological properties.

The method is simple, does not require complex equipment and can be implemented in the conditions of any medical institution.

An example. A sterilizable object, such as a hand, is placed in a container filled with a preparation containing microparticles. Then on Wednesday in which there is an obrabat. four

The best object is that ultrasonic vibrations are introduced with a frequency of 6 = 26.5 kHz and an intensity of 3 = 1 W / cm ² for 5 minutes. As microparticles suitable for use in medical practice, M cells are used (sostossyz 1 ZoOEϊs I! Siz B = 80, treated with 40% formalin solution.

Microparticles in the field of ultrasonic waves affect the treated area of biological tissue, enhancing the sterilizing effect of ultrasound. After removing the ultrasonic effect, the microparticles remaining on the biological tissue, for some time, completely decompose in the biological tissue.

The proposed method allows to improve the quality of sterilization of biological tissue by increasing 2

the effectiveness of ultrasound while maintaining its biological properties. At the same time, the complete sterilization of the object is significantly reduced and reaches 30-50 seconds.
