Abstract

(57) [Abstract] [Purpose] When a substance such as bacteria, isotopes, and fine particles on the surface of the sample T is collected by wiping with a gauze G held by tweezers P, a gauge that can accurately limit the wiping area is obtained. I want to. [Structure] A handle 3 made of an elastic material is fixed by welding to one side of a frame body 2 made of a thin elastic plate and having an opening of a certain area. Even if the surface of the sample T is concave or convex, when the handle 3 is pressed against the surface while being compressed in the direction of the arrow A, the frame body 2 is curved and adheres closely to the surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used to collect bacteria, isotopes, particles, etc. adhering to the surface to be inspected by wiping with a gauze to measure the number of bacteria, radioactivity, particles, etc. For gauges to be limited to a certain amount.

[0002]

[Prior art]

 In the conventional gauge, the middle part of the wire was bent into a square of a certain size to form a frame, and both ends of the wire were twisted together to form a handle, which was manufactured and used on site. However, many specimens have a curved surface that is convex or concave like carcass, and the frame made of conventional wire cannot conform to the curved surface, so a certain surface area is specified. In addition, since the gauze for wiping off during the work easily sticks out from the lower surface or the upper surface of the frame body, there is a disadvantage that accurate collection cannot be performed.

[0003]

[Problems to be solved by the device]

 It is an object of the present invention to obtain a gauge that can be in close contact with the surface to be inspected and can accurately limit the wiping area.

[0004]

[Means for Solving the Problems]

 The problem in the present invention is to provide a frame body having an opening of a certain area, which is formed of a thin plate that can be easily elastically deformed according to claim 1, and a width direction of the frame body extending upward from the frame body. A handle which can be elastically deformed, or a rectangular frame body having an opening of a certain area, which is formed of a thin plate which can be easily elastically deformed, and an outer side. A flexible handle having a U-shaped grip portion extending to the upper side of one side of the frame body is fixed to the upper surface of the frame body.

[0005]

As described above, since the frame body is made of a thin plate that is easily elastically deformed, when the surface of the sample is concave, the frame body is pushed along the concave surface by pressing the frame body against the concave surface. It can be bent and brought into close contact, and in either case of convex or concave surface, by applying compressive force in the width direction to the handle while pressing the frame against the surface, deformation along the convex or concave surface can be performed. it can.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4, 1 is a gauge for collecting adhering substances of the present invention, 2 is its frame, and 3 is a handle. The frame body 2 is made of a thin leaf spring material and has four sides 2a, 2b, 2c and 2d and a square opening 4. The opening 4 has a length L ₁ (FIG. 2) on one side of, for example, 50 mm or 100 mm, and has a constant area which is defined by the L ₁ . The width L ₂ of the frame is arbitrary, but is, for example, 5 mm. The handle 3 is made of elastically deformable steel wire and has a U-shaped and outwardly curved grip portion 3a and an expanding portion 3b. It is welded to both ends of one side 2a.

To use the gauge 1, hold the handle 3 with one hand to bring the frame body 2 into close contact with the test body T as shown in FIG. 1, and hold the gauze G via the tweezers P with the other hand. Then, while applying a substantially constant pressure to the gauze G, the surface of the sample T in the opening 4 is rubbed at all corners to wipe off the adhered matter on the surface, and the matter adhered to the gauze G is separately measured.

[0008] When the sample surface is flat, may be held stationary and the frame 2, when the sample surface is concave, the concave S ₁ the frame 2 via the handle 3 as shown in FIG. 5 When the handle 3 is pressed from both sides in the direction of the arrow A to reduce the width while pressing the frame body 2 against the concave surface S ₁ from a direction different from that shown in FIG. 5, as shown in FIG. The body 2 curves downward and adheres to the concave surface S ₁ . At this time, the side 2a is directly bent by the compression of the handle 3, but the sides 2b and 2d are also inclined in the width direction, so that the side 2c is also bent by the sides 2b and 2d from both sides, and the side 2a and the side 2a are bent. It also bends.

When the surface of the sample is convex S ₂ , the handle 3 is moved in the direction of arrow A, that is, in the same manner as in FIG. 6, while the frame 2 is applied to the convex S ₂ to prevent bending downward as shown in FIG. Compress to. By this compression, the frame body 2 is extruded upward and adheres closely to the convex surface S ₂ .

In this way, the frame body 2 adheres to the sample T regardless of the surface shape of the sample T, so that the gauze G is prevented from coming out of the opening 4 from under the frame body 2 during the wiping operation. Further, since each side of the frame 2 has a constant width, it is possible to prevent the sample surface outside the frame from being rubbed over each side, and accurate wiping can be performed.

Although steel is used for the frame 2 and the handle 3 in the above-described embodiment, an elastic material such as a hard plastic can be used, and the grip portion 3a of the handle 3 is as shown in the figure. It is convenient not to be directed backward but to be directed upward, but it does not matter if it is directed upward.

[0012]

[Effect of device]

 As described above, according to the present invention, since the frame can be easily deformed along the sample surface, the wiping area can be accurately limited, and the adherence of adhered substances such as bacteria, isotopes, and microparticles can be achieved. It has an advantage that the density can be detected accurately.
