Description

[Detailed Description of Device] a. Purpose of the invention (industrial field of application) The present invention relates to a dental treatment instrument tray which can completely prevent bacterial infection during medical treatment without disinfection by exchanging the inner tray for each patient. .

(Prior Art) Conventionally, a container and a convenient tray for dentistry are disclosed in JP-A-52-7359.
No. 3, which is a combination container comprising an outer container having sides and a bottom, a tray made of a relatively thin bendable material supported by and fixed to the container, The tray has a number of recesses therein for holding the articles to be used, the bottom of the deep recesses being fixed to the bottom of the container by an adhesive, A dish for mixing monomers is detachably supported in the recess of the part, and this dish is configured to be removed and discarded when the mixed monomers cure, and only protects it while handling or shipping various items. However, as described in the publication, the article has a feature that it can be easily obtained during use by arranging and supporting the article in an attractive and convenient manner.

(Problems to be solved by the device) However, this container / convenient tray can be removed by discarding only the mixing container when the monomer hardens and becomes unusable, but the other parts of the tray are outside due to the bottom of the deep recess. Since it is attached to the container and cannot be removed, when the equipment used during treatment is placed in the tray, the equipment, gloves, etc. touch the tray and transfer the attached bacteria to the tray. There is an annoyance that must be done, and the tray with irregularities is incompletely disinfected and bacteria remain.
This causes a serious problem that a doctor is infected with the modern intractable disease AIDS, which is highly contagious because it is transferred from the equipment and gloves to the patient and there is only a preventive measure.

The present invention has been made in view of this situation, and by fitting the inner tray to the outer tray to cause bacterial contamination on the outer tray and removing the contamination by removing the inner tray, disinfection is not required and bacterial infection is completely eliminated. The present invention provides a dental treatment instrument tray which can be prevented and does not increase the cost burden.

B. Configuration of the Invention (Means for Solving the Problems) The dental treatment instrument tray according to the present invention comprises an outer tray formed of an appropriate material so as to obtain strength and weight necessary for stable support of the treatment instrument. , A thin synthetic resin sheet that can be deformed into a thin rod when twisted, is formed to fit the inner shape of the outer tray, packaged and stored after complete sterilization, and opened and fitted to the outer tray to fit the outer tray. The problem is solved by a configuration in which the surface to be contaminated is completely covered, the surface is contaminated, and this contamination is combined with an inner tray that is carried away when removed from the outer tray.

(Operation) In the dental treatment instrument tray having the above-described configuration, when the inner tray is fitted into the outer tray, the thin and weak inner tray is supported by the outer tray having strength and weight, so that the required strength and stability can be obtained. When given, the inner tray completely covers the contaminated surface of the outer tray, and when the equipment is taken in and out at the time of medical treatment, when the equipment or gloves touch and transfer the adhered bacteria, it receives it on the surface and finishes the medical treatment. After removing the instrument for disinfection, the inner tray removes germs when removing the inner tray from the outer tray, and the outer tray is fitted with a clean, disinfected inner tray to carry out the next medical treatment. Even without treatment, bacterial contamination is completely prevented and AIDS for intractable diseases is completely prevented.

Further, since the inner tray is formed of a thin synthetic resin sheet that is deformed into a rod shape when twisted, it can be provided on the market at the cost of the cost conventionally required for disinfecting the tray, and it can be taken out from the outer tray. After that, if the inner tray is exchanged for each patient by twisting it into a thin rod and discarding it, the volume of dust becomes very small even if the number of uses is large.

Furthermore, since the outer tray and the inner tray are detachably fitted,
Since an air layer is present between both trays to provide a cushioning action, no unpleasant sound is emitted when the device is put in and out even when a metal outer tray is used.

(Embodiment) An embodiment of the dental treatment instrument tray according to the present invention will be described below with reference to the drawings.

In each drawing, 1 is an inner tray, which has excellent water resistance, chemical resistance, etc., is harmless to the human body, and is inexpensive synthetic resin, such as polypropylene, which is thin enough to be deformed into a thin rod shape when twisted,
That is, using a thin sheet a having a thickness of 0.1 mm or less, it is formed by the simplest vacuum forming so as to match the inner shape of the outer tray as shown in FIGS. 1 and 2, and a part of its bottom is formed. In order to arrange medical instruments (which are publicly known and therefore omitted in the drawing) so as to be easily used, partition projections 2 are provided laterally at predetermined intervals as shown in FIG. 1, or not shown in the drawing. Grooves and ridges are alternately provided in the vertical direction.

The inner tray 1 is placed in a disinfecting apparatus to be completely disinfected and made aseptic, and then individually or a required number are collectively packaged and stored so that bacteria are not contaminated even in stock.

The sheet a forming the inner tray 1 is a synthetic resin sheet a as shown in the enlarged circle in FIG. It is also possible to use a multi-layer structure in which the above are laminated, but in this case, the price will be somewhat higher.

3 is an outer tray, which is made of a metal such as stainless steel or an enamel iron plate, or a material c such as a synthetic resin having an appropriate thickness,
Formed in the shape shown in Fig. 1 and Fig. 2, the strength is such that the side does not deform even if the medical instrument is placed across the bottom and side, and the degree that it does not move stably in the placed position. It is formed by pressing or molding so as to obtain the weight of.

The outer tray 3 is fitted with the sterilized inner tray 3 taken out from the package on the inner side of the outer tray 3 so that the thin inner tray 1 is supported on the outer side so that stable support of the device can be performed. The surface to be contaminated with bacteria is completely covered by the inner tray 1 so that the surface is contaminated with bacteria, and this contamination is carried away when the inner tray is removed from the outer tray.

C. Effect of the Invention As described above, in the dental treatment instrument tray according to the present invention, the inner tray is fitted to the outer tray to cause bacterial contamination, and the contamination is taken away by removing the inner tray. It can completely prevent bacterial infections without the use of a medicine and have a perfect effect in the prevention of AIDS.

Since the inner tray is made of a thin synthetic resin sheet that can be deformed into a thin rod shape when twisted, it can be manufactured at a price such as the disinfection cost of the tray, so it does not increase the cost burden even if it is disposable, and it is already used After that, if the inner tray is twisted into a rod shape and discarded, the inner tray can be exchanged for each patient and a large number of dust can be used, so that the volume of dust can be made extremely small.

Since the outer tray has the necessary strength and weight, the inner tray can be fitted to support the equipment securely and stably even with a thin inner tray. Moreover, an air layer is created between the inner and outer trays to cushion it. Even if the metal outer tray is used, no unpleasant sound is generated when the device is taken in and out because of the function.
