Abstract

PROBLEM TO BE SOLVED: To provide safely reusable means causing no problems of a cost and residual components of antiseptic solution in a denture brush.SOLUTION: An upper surface side of a heat-resistant thermosetting resin handle (1) is filled with upper-face heat-resistant bristles (21) and the lower surface side thereof is filled with lower-face heat resistant bristles (22). The denture brush has 135°C or more heatproof temperature. Polypropylene resin is used as the heat-resistant thermosetting resin, and polyamide 610 and polyphenylene sulfide are used as the heat-resistant bristles. The denture brush is sterilized by an autoclave within a temperature from 121°C to 135°C.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a denture brush and a method for sterilizing a denture brush.

A typical denture brush has a heat-resistant temperature of about 80 ° C., and a nylon handle brushed on a polypropylene handle is widely used.
When the denture brush is used in a dental clinic or the like, it is desirable to use it in consideration of hygiene.
However, in order to consider cost normally, used denture brushes are reused by disinfecting them with a chemical solution.

  In Patent Document 1, in the oral hygiene device formed on the pedestal by the brush portion electrostatically flocking the bristle through the binder, at least a portion of the brush portion alternately with the flocked region and the non-flocked region, An oral hygiene device is described in which the shortest pitch interval from the center or center line of one flocked area to the center or center line of an adjacent flocked area is 1 to 20 mm.

  When a general denture brush or an oral hygiene device described in Patent Document 1 is sterilized with a disinfectant, it may be affected by the disinfectant and a more complete treatment has been desired. .

  Means for solving the problems of the present invention are as follows.

First,
A denture brush, wherein a heat-resistant bristle is implanted in a handle made of a heat-resistant thermoplastic resin, and the heat-resistant temperature is 135 ° C or higher.
Second,
Polypropylene resin is used as the heat-resistant thermoplastic resin,
The denture brush according to claim 1, wherein polyamide 610 and poniferlen sulfide are used as the heat-resistant bristle.
Third,
A denture brush with a heat-resistant thermoplastic resin that has a heat-resistant bristle planted on it and a heat-resistant temperature of 135 ° C. or higher.
A denture brush sterilization method comprising sterilizing by an autoclave.

  According to the present invention, the following effects can be obtained.

  The denture brush according to the present invention has a heat-resistant temperature of 135 ° C. or higher and can be sterilized by an autoclave, so that the remaining components do not cause a problem and can be safely reused.

It is a perspective view of the denture brush of this invention. It is explanatory drawing of the denture brush shown in FIG. 1, (A) is a top view, (B) is a side view.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
Here, in the accompanying drawings, the same reference numerals are given to the same members, and redundant descriptions are omitted.
In addition, since description here is one form by which this invention is implemented, this invention is not limited to a corresponding form.

  The denture brush shown in FIG. 1 and FIG. 2 has an upper surface heat resistance of the same height by a polyamide 610 having a heat resistance temperature of 140 ° C. or higher on the top surface side of the natural color handle 1 made of polypropylene having a heat resistance temperature of 140 ° C. In addition to flocking the bristle bristle 21, the lower surface heat-resistant bristle 22 having a high central portion and a low surrounding area by poniferlen sulfide having a heat-resistant temperature of 220 ° C. is planted on the lower surface side which is the opposite surface side. is there.

Here, as the polypropylene, Frey Polymer Co., Ltd. polypropylene resin was used. As the polyamide 610, Toray Monofilament Nylon 610 monofilament was used. As Poniferlen sulfide, Toray Monofilament 730T was used.
All of these substances have been confirmed to have no safety problems.

  The lower surface heat resistant bristle 22 is formed to be harder than the upper surface heat resistant bristle 21, and is suitable for polishing a recessed portion or the like because the center portion is high and the periphery is low. .

Characters are printed on the upper surface side of the handle portion of the handle 1.
Here, the characters are printed using an ink whose color changes with a certain temperature change and the number of times, so that it functions as a sign to notify the replacement time when the sterilization process by the autoclave described later is repeatedly performed. It can also be configured.

After use, the denture brush was placed in an autoclave and continuously sterilized at 121 ° C. for 20 minutes, 132 ° C. for 5 minutes, and 135 ° C. for 3 minutes.
As a result, it was confirmed that it was sufficiently sterilized.
In addition, since the disinfectant is not used, the remaining components due to the disinfectant do not become a problem.

  As a result of performing a heat resistance test on the denture brush, it was confirmed that there was no influence of thermal deformation or the like within a range up to 160 ° C.
