The Institute of Technical Acoustics offers consumers the ultrasonic sealer ZU-100 for blood bags and blood processing lines under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

The Institute of Technical Acoustics of the National Academy of Sciences of Belarus developed a medical device for sealing blood bags and blood processing lines - ultrasonic sealer ZU-100.

The device contains:
1) an ultrasonic generator,
2) a piezoelectric transducer,
3) a cutting element and
3) a movement mechanism.

The generator converts the electric energy into the energy of electrical vibrations in ultrasonic range, which than is converted into mechanical vibrations by the piezoceramic transducer and is transmitted through a waveguide into a polymer tube. Ultrasound, acting on the polymer material, melts it, and the movement mechanism provides constant compression of the tube, thereby welding it.

Specifications of the ZU-100
tube diameter	3..6.5 mm
welding time for tubes	4..6 seconds
power consumption:
standby	20 W
welding	100 W

The ultrasonic device is used by haematology centres and centres of blood transfusion for sealing blood bags and blood processing lines.

Album of promising developments of organizations of the National Academy of Sciences of Belarus for the real sector of the economy (in Russian).

Compared to low-performance mechanical joining methods and environmentally hazardous gluing operations, ultrasonic welding is environmentally friendly and provides higher productivity due to faster welding process, the ability to quickly change the welding tool, low weight and transportability of the device.

Using the ZU-100 brewer, the welding cycle for tubes filled with blood and its components is only 4–6 seconds. The diameter of the welded tube is from 3 to 6.5 mm.

The use of the ultrasonic method for connecting thermoplastic tubes in healthcare institutions of the Republic of Belarus has shown its high environmental friendliness and safety.

ZU-100 is used at blood transfusion stations in the Republic of Belarus.

The Institute of Technical Acoustics is a leading organization in the field of new directions in the physics and technology of ultrasound and the scientific foundations of the use of high-power ultrasound in technological processes of materials processing.

At the present stage, the activities of the Institute correspond to the priority areas of scientific, technical and socio-economic development of the country and the Vitebsk region. The Institute conducts fundamental and applied research, and also carries out scientific and technical developments within the framework of state scientific research programs (GPNI), regional scientific and technical program (RSTP), republican and international projects of the Belarusian Foundation for Basic Research (BRFFR), individual projects and grants in fields of semiconductor physics, magnetoelectric phenomena, ultrasonic vibrations, thermoelastic phase transformations, etc.

Scientific areas of activity of the Institute:
- study of the impact of concentrated energy flows on condensed media and physical processes;
- development of methods and technologies for obtaining materials for functional and special purposes.

A branch of the Republican Center for Technology Transfer has been created at the State Scientific Institution “Institute of Technical Acoustics of the National Academy of Sciences of Belarus”, the main activities of which are:
- support for innovation and technology transfer in the field of using concentrated energy flows (ultrasound, laser radiation, high-frequency electromagnetic fields, ion-plasma flows, high-temperature synthesis) on the structure and properties of condensed matter; synthesis of new composite, structural and ceramic materials with specified physical and mechanical properties in an ultrasonic field; processing of metals using thermal methods, pressure and powerful ultrasound; development of new instruments and equipment, creation of new information technologies;
- promoting the development of innovative entrepreneurship and the expansion of international partnerships in the field of innovation and scientific developments;
- providing assistance in the implementation of state policy in the field of small and medium-sized innovative businesses in the creation of new technologies, the development of new devices and equipment.

The Republican Center for Ultrasound Technologies, which is an interdisciplinary scientific and technical center (cluster) for advanced scientific research, has been created at the State Scientific Institution “Institute of Technical Acoustics of the National Academy of Sciences of Belarus”. The center was created with the aim of developing new highly efficient processes and devices for processing materials, creating new functional materials to improve the quality of products, reduce costs and increase the level of safety of production using high-power ultrasound. The expected scientific results of the center’s work are aimed at obtaining new scientific knowledge about the influence of acoustic influences on:
- structure formation and properties of materials;
- technological processes;
- thermoelastic phase transformations in materials with shape memory.

The expected practical results are aimed at mastering new technologies and developing unique equipment with high export potential.
