RU164744U1 - PLASTIC BOXING FOR STERILIZATION BY THE METHOD OF AUTOCLAVING AND STORAGE OF SMALL MEDICAL INSTRUMENTS - Google Patents

Abstract

Plastic box for sterilization by autoclaving and storage of small medical instruments, characterized in that it consists of: a base equipped with holes, a displaceable insert, segmented and equipped with holes in the base, and a cover that fixes the position of alignment or separation of the holes when the insert is displaced.

Description

The utility model relates to medicine, in particular to practical dentistry, and can be used to sterilize dental instruments.

When sterilizing dental instruments using standard metal boxes, they become deformed and corroded over time, as well as their long-term use can damage the sterilized instruments.

There are three types of sterilization:

1) Steam method (water saturated steam under overpressure) Equipment used: autoclave.

2) Air sterilization method (dry hot air) Equipment used: dry heat cabinet.

3) Chemical method (solutions of chemical preparations). Applied products: chemical disinfectants (hydrogen peroxide, deoxone, alaminol, prespept, etc.) (1)

1) Steam - which is worth focusing on

t-132 s; P-Bar 1.1-2.0; Min 5-20

Full cycle (min) 6-30

Applicability Metal, glass, textile, rubber, PVC, latex

Sterilizing agent Steam, temperature, pressure

Benefits

Short full cycle

Sterilization of heat-sensitive products is possible.

Use of various types of packaging.

disadvantages

Higher cost of equipment

2) Air

t-170 s; P-Bar 1.1-2.0; Time min 30

Full cycle (min) 75-120

Applicability Metal, glass

Sterilizing agent temperature

Benefits

Low cost of equipment

disadvantages

Long cycle

High temperature damage hazard

Application restriction

Exposure to one temperature control parameter

High power consumption

3) Chemical - which does not interest us at the moment.

As you can see, the steam sterilization method, or autoclaving, has a great advantage over the others. The short cycle and low temperatures make it possible to use this method to sterilize almost all instruments and consumables used in medicine.

When sterilized in steam and air sterilizers, products are usually sterilized packaged in sterilization packaging materials; with the steam method, in addition, sterilization boxes without filters and with filters are used. (2)

Medical instruments, dental kits sterilized in an individual sterilization package (double soft calico, packages of wrapping paper, parchment) can be stored in a dedicated cabinet. With the air sterilization method, as well as in some cases with the steam method, sterilization of instruments in unpacked form (in open trays) is allowed, sterilized instruments should not be stored in the sterilization chamber.

The closest to the claimed utility model among the known is a sterilization box. A sterilization box of a square, rectangular or other shape, made with perforated side walls, equipped with shutter valves that overlap the holes, consisting of several compartments, characterized in that the whole box is divided by a common horizontal partition into two parts, which, in turn, are divided by vertical partitions into compartments equipped with individual covers that open in opposite directions and are locked with spring-loaded latches. USSR patent 73189 of August 26, 1947 (3)

The disadvantage of the method, in our opinion, is the use in this case of sterilization boxes made of materials that are subject to deformation under the influence of high temperatures and pressure over time, as well as their large size, which complicates the transportation of tools; and the use of open trays, which can lead to damage to the toolkit, or to its loss during sterilization.

Purpose of work: To optimize the sterilization process of dental instruments.

The proposed utility model is shown in FIG. 1 - FIG. 10:

FIG. 1 - side view of the model in assembled condition

FIG. 2 - side view of the model base

FIG. 3 - side view of the model insert

FIG. 4 is a side view of the combined base and insert of the model.

FIG. 5 is a top view of the model cap

FIG. 6 - bottom view of the model cover

FIG. 7 is a top view of the model insert

FIG. 8 - bottom view of the model insert

FIG. 9 is a top view of the model base

FIG. 10 is a bottom view of the model base

Where,

1 - insert cells

2 - insert

3 - insertion position "open"

4 - base

5 - insert holes

6 - holes of the base

7 - insertion position "closed"

After pre-sterilization cleaning, disinfection and drying, the tool is placed in the cells (1), the plastic box closes, the insert (2) moves to the “open” position (3), in which the base (4) and the insert are displaced relative to each other. The insert holes (5) and the base holes (6) in this position are aligned. After sterilization in an autoclave, the middle part moves to the “closed” position (7), in which the openings on the bottom of the insert and the bottom of the base of the box are not aligned.

The essence of this invention lies in the fact that during steam sterilization, the instrument is subjected to steam treatment inside the presented plastic box through the holes of the base and insert, which can optionally disconnect after the sterilization process and in such a state isolated from the external environment can be transported to the doctor’s place of work, bypassing the stage packaging of instruments from a sterilization box by junior medical personnel, in which there is a human factor (loss, incorrect fa scoop).

Advantages of the proposed model:

1) Plastic does not change its physicochemical properties over time, does not corrode, and does not allow corrosion of the tool.

2) The holes for the passage of steam at the time of the sterilization cycle are combined with each other, when the insert is moved with the cells relative to the base, they do not fit, thereby closing the space inside from the ingress of non-sterile air from the outside.

3) The holes in the configuration do not allow the small tool to fall through and deform.

4) The use of boxing increases the free space on the desktop by reducing additional containers with tools.

5) Easy to manufacture and use by staff.

The proposed technical invention is most convenient to use. It is made of medical autoclavable plastic. It is an organizer of a small tool with repeated use with the ability to sterilize and maintain sterility of the attachment at the time of use.
