Filed: 2009-08-25
Abstract: Provided is a medical part with excellent antibiotic properties and antibiotic substantivity as well as high biocompatibility, and a manufacturing method therefor. After an anodic oxidation treatment, wherein a pulsed current with a frequency of 50 to 10,000 Hz is applied for an electrolytic treatment, is applied to a base material in an acidic electrolytic bath or an alkaline electrolytic bath so as to form a film, which has minute holes and/or minute protrusions and recesses preferably in the quantity of 5 x 104/mm2 or more on the surface of the base material, an iodine-impregnation treatment is applied so as to impregnate iodine or an iodine compound into said film. Polyvinyl pyrrolidone iodine, ß-cyclodextrin iodine, or silver iodine is desirable for the iodine compound. Furthermore, a biocompatible metallic material selected from Ti, Ti alloy, stainless steel, and Co-Cr alloy is desirable for the base material. The film may be formed by means of a chemical treatment, a thermal treatment, or a machining process, or a combination of these, instead of the anodic oxidation treatment. Thus, a medical part with excellent antibiotic properties and antibiotic substantivity as well as high biocompatibility can be manufactured easily and inexpensively.

Abstract: The invention relates to improvements to a hydraulic actuating device for lifting and lowering the lid of a WC, characterised by a left module and a right module consisting of a housing comprising a central transverse axle, the ends of which jut out, said housing being divided into three compartments. The end of the left axle is connected to the lid and the end of the right axle to the seat, the opposite end being fixed to a driving plate having three wings, a wing being housed in each cavity of the housing, which also house a cylindrical diaphragm. Said diaphragms, when filled with water, press on the wings, simultaneously causing a partial rotation of the axles which, as they are coupled to the lid and seat, lift the lid and seat together or separately and lower them during the rotational displacement when the water is released. Said diaphragms are fed via a check valve enabling the passage of feed water for filling the diaphragms and for discharging the diaphragms by means of a duct to the tank of the WC when the flush is actuated. Said left and right valves that are actuated by foot are connected to a general water distributor connected to the water supply duct.

Abstract: A pipette is provided with a cylinder (1) having a front end (1a) to which a pipette tip (3) is removably attached, and also with a piston (7) fitted in the cylinder chamber (6) so that the piston (7) can be advanced and retracted, and the pipette sucks liquid when the piston (7) is retracted and discharges the sucked liquid when the piston (7) is advanced. A communication groove (17) is provided in the outer periphery of the piston (7). The communication groove (17) is located outside the cylinder chamber (6) when the piston (7) is located at the retracted position, and the communication groove (17) causes the inside and outside of the cylinder chamber (6) to communicate with each other when the amount of advance of the piston (7) is greater than a predetermined dimension. When the amount of advance of the piston (7) is greater than the predetermined dimension, the sealing between the cylinder chamber (6) and the piston (7) is rendered ineffective. This causes the pressure within the cylinder chamber (6) to be the same as the atmospheric pressure, thereby cancelling the suction/discharge effect.
