EA000393B1 - Container for storing sterile medical instruments "panmed 1" - Google Patents

Abstract

A container for storing sterile medical instruments, comprising a bactericidal tube arranged horizontally in the upper portion of said container and a window to put instruments, and also hingely mounted cover in said container, said cover opens inwards of the window, enabling to interrupt the tube operation, characterized in that along the edges of the cover and the window shields are fastened, forming labyrinth sealing, arranged in the closed position with mutual overlapping, said shields enable to overlap the window in the process of lifting the cover to full interruption of the tube action.

Description

The invention relates to medical technology and is a device for storing pre-sterilized medical instruments.

Usually such tools are stored in movable large and small tables intended for direct support of operations and dressings (USSR Author's Certificate No. 1470297, IPC A 61L 2/10, 1989). After the first extraction of instruments from such tables, the others lose their sterility, coming into contact with dust and room air.

This disadvantage is partially eliminated in the device according to patent RU 2043774, IPC A 61E 2/10, 1991, which is adopted as a prototype, as the closest analogue of the present invention by the combination of essential features and technical essence. A device for storing sterile medical instruments according to the patent contains a housing with a germicidal lamp horizontally in the upper part and an access opening for instruments, as well as a lid hinged in the housing that opens inside the opening and is designed to insulate the lamp in the open position. This design, however, as will be shown below, allows ultraviolet radiation from the lamp through the opening at the initial moment of opening the lid, which is highly undesirable. In addition, when disinfecting a room, disinfecting solution may get into the housing through leaks in places where the opening and the lid are mated.

This invention is devoid of these drawbacks and is achieved by the fact that in a device for storing sterile medical instruments, comprising a housing with a bactericidal lamp horizontally located in the upper part and an opening for accessing the instruments, as well as a lid hinged in the housing opening inside the opening the ability to isolate the lamp in the open position, along the edges of the lid and opening is reinforced located in the closed position with mutual overlap, forming a labyrinth seal shield and made with the possibility of overlapping the opening in the process of opening the cover to complete isolation of the lamp.

FIG. 1 shows a general view of a device for storing sterile medical instruments;

in fig. 2 shows a cross section of the device with the lid closed;

in fig. 3 - the same with the lid open; in fig. 4 - the same with the lid ajar; in fig. 5 is a section according to A-A of FIG. 2; in fig. 6 is a cross section of the prototype device.

The device for storing sterile medical instruments comprises a housing 1 with a bactericidal lamp 2 horizontally located at the top and an opening 3 for accessing the tools, as well as a cover 4 pivotally mounted in the housing, opening inside the opening and configured to isolate the lamp 2 in the open position. Along the edges of the cover 4 and opening 3 are reinforced located in the closed position with mutual overlap, forming labyrinth seals, respectively 5 and 6.

In the closed position of the cover, the instruments on the grating P are irradiated with an ultraviolet lamp 2, which ensures their sterility. To access the instruments stored on the grille P, turn the lid 4 counterclockwise. At the initial moment of opening the lid 1, i.e. when turning it at a certain angle along arrow a (see Fig. 4), the overlap of the flaps 5 and 6 on the side and bottom edges of the opening 3 and the cover 4 is retained. Due to this, the opening 3 remains closed and the radiation from the ultraviolet lamp 2 does not penetrate the room. At the same time, the flap 5 along the back edge of the lid gradually covers the compartment of the housing in which the lamp 2 is located. The dimensions of the flaps 5 and 6 are chosen so that the full insulation of the lamp 2 by the lid 4 occurs somewhat earlier than opening 3. Thus, the penetration into the room reflected from the internal surfaces of the radiation housing from the lamp 2 and the extremely undesirable exposure of personnel using the device is completely excluded

At the same time, a prototype device similar in purpose, the cross-section of which is shown in FIG. 6 (designations of identical elements are the same as in Figs. 1-5), in the process of turning the lid 4 from the closed position at a certain angle δ, the ultraviolet radiation reflected from the internal surfaces enters the room through the slots between the lid 4 and the edges of the opening 3. In addition When disinfecting a room with solutions, the latter can get into the housing 1 through leaks in the place where the edges of the lid and the opening meet. Naturally, the solution may get on sterile instruments, which is completely unacceptable. In the device according to the invention, the flaps 5 and 6, which in the closed position of the lid form labyrinth seals, prevent the ingress of moisture into the body.

Thus, this invention ensures the sterility of stored instruments and the safety of personnel.
