STERILIZING BOXES — tanks for placement of a dressing material, operational linen, surgical instruments, gloves and other objects at their sterilization, delivery to the place of use and the subsequent short-term storage (steam sterilizers). Page to. allow to create in to lay down. - prof. institutions a reserve of sterile materials for performing urgent surgeries also promote the centralized use of the sterilizing equipment (see. Scientific organization of work ).
In the second half of 19 century in Moscow G. W. Mendel suggested to apply zinc boxes to the room in them a dressing material at sterilization. Later for tools during the autoclaving E. Braatz offered wire baskets (E. Braatz's box), and A. Diihrssen — tin cylindrical boxes with openings on perimeter, in day and a cover. K. Shimmelbush applied a tetrahedral box with a trellised bottom (Shimmelbush's box) to sterilization of materials.
Now round and rectangular S. are applied to., with the filter and without filter. Their main technical characteristics are given in the table.
Round S. to. without filter (steam sterilizers) are intended for use in sterilizers (see), having preferential cylindrical sterilizing camera. They consist of the case, a cover and the belt (fig. 1) moving on the case. In the case and in a belt there are openings, to-rye for sterilization (before the room in a sterilizer) are combined. At S.'s unloading to. from a sterilizer the belt is displaced, closing thus openings in order that the sterile tools and materials which are in S. to., did not adjoin to air of the room. Sterility of material at the same time remains to 3 days. The belt is supplied with the tension lock excluding its spontaneous movement.
S. are applied to longer preservation of sterility of materials (up to 20 days) to. round KSKF type (fig. 2) and rectangular KSPF type (fig. 3). They are supplied biol. the filter from textile materials (filtrodiagonal, a nonwoven napkin, otbelny coarse calico, muslin, to madapola, etc.), to-rye fasten from the inside of the case and a cover.
It is recommended on S.'s bottom to. before laying of materials to put laying (cotton, a gauze or other material) in it, in to-ruyu the moisture accumulating after sterilization will be absorbed. Separate objects (tools, gloves) before laying in S. to. it is better to wrap a double layer of a gauze and it is free (on an edge) to lay in S. to. Linen, a dressing material shall be curtailed into flat packages and without consolidation are placed in S. to. too on an edge so that between them the palm freely entered. At S.'s closing to. the cover is locked. The cover shall not squeeze S.'s contents to. At sterilization for control of temperature in S. to. use tests with substances, temperature of melting to-rykh is known (sulfur melts at 115 °, the benzoic to - that at 122 °, etc.). These substances in the form of powder in bottles or test tubes place in S. to. among the sterilized material and upon termination of sterilization check, powder melted or not. Sometimes add indicators to powder — safranin, tetraethyl-diamino-triphenyl-carbohydride sulfate, etc., painting them at the time of melting in the corresponding color. Attach a label on which specify date of sterilization, a surname of the employee making laying, the list of the objects of sterilization which are in S. to the lock of the closed cover., and at the centralized sterilizing — department.
