Abstract: A method for obtaining pure drinking water from dewatered biological products is described. The process is carried out in a hermetic dewatering chamber isolated from the ambient atmosphere and in parallel with a process during which dried products are placed on drying trays. All the process parameters, such as temperature, humidity, and appropriate pressure inside the chamber, are controlled. The vapor generated during the product dewatering process, released from the products, is continuously removed from the dewatering chamber through the upper opening, exits through the outflow channel, and enters through the condenser. The process of obtaining clean drinking water is carried out outside the chamber and is conducted in several stages: vapor passes through disinfectant grids, vapor flows to a condenser cooled with ice water, and the vapor condenses on densely arranged lamellas. The condensate is then pumped to a discharge tub.

Abstract: The subject matter of the invention is a process of dehydration of biological products using the pressurized drying method in which the product is treated with a gaseous medium the movement of which over the dried product is forced in a closed system under appropriate pressure, in the presence of a difference between the temperature of the medium circulating in the system and the temperature of the dried product until the product moisture content is reduced to the desired level, and in which the dehydration process is executed at a constant temperature of the atmosphere surrounding the material, preferably higher than its storage temperature but lower than the degradation temperature of its components.

Abstract: A method and device for cutting venous valve located within the lumen of a vein. The device comprises an elongate shaft of rigid or flexible construction and a valvulotome blade positioned on the distal end of said elongate shaft. The valvulotome blade comprises an elongate shank portion which is disposed substantially parallel to the longitudinal axis of the shaft, and a head portion which extends laterally from the shank portion of the blade. The head portion of the blade comprises an outer venous wall abutment surface and a proximal cutting surface. The venous wall abutting surface is a spaced distance from the proximal cutting surface such that the venous wall abutment surface may be forced into abutment with the venous wall and the device may be drawn through a venous valve such that the proximal cutting surface will cut the venous valve, but will not come into contact with the adjacent vein wall.

Abstract: A closure lid for a rigid, disposable container for safely containing and disposing of medical-surgical materials, including needles, syringes, scalpels and dressings after use, comprises two lightweight plastic pieces which snap together without tools to form a closed container having a large opening for the insertion of used materials therethrough, which opening can be permanently sealed by sliding a flush cover to a closed and locked position preventing the inadvertent expulsion of macroscopic material from within the container. A one-way barrier is provided at the large opening for the protection of the user, which barrier can be removed if desired, and additional apertures having sharps-removing features molded therein to permit the simultaneous removal of sharps from associated devices and their disposal therethrough.
