JP2002173176A - Package for dental x-ray film - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a package for a dental X-ray film, in which the development and fixing of the film are execuable without injecting a chemical liquid and which prevents the chemical liquid from leaking out of the package even during the development and fixing. SOLUTION: A chemical liquid bag 20, which is packed with a chemical liquid 21, and an X-ray film 30 are stored in a plain bag main body 10. The chemical liquid bag 20 is made breakable by pressing it from an outer face of the flat bag main body 10. After an X-ray photographing, the chemical liquid bag 20 is broken, and it is designed so that the developing and fixing liquid is thereby caused to flow into the plain bag main body 10.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dental X-ray film package.

[0002]

2. Description of the Related Art In order to take a radiograph of the condition of one or two teeth in the oral cavity, a small X-ray film is applied to the inner surface of the tooth and held by a finger. An X-ray irradiation method has been adopted.

After X-ray photography, it is necessary to develop and fix the X-ray film. To save the trouble as much as possible,
In some cases, an X-ray film is sealed in a bag in advance, and a single bath solution (developing and fixing solution) is injected into the bag after X-ray photography. FIG. 4 shows the package. As shown in the drawing, the bag body 1 is made of a synthetic resin flat bag such as vinyl chloride with three peripheral edges 1a, 1b, and 1c sealed.
In the vicinity, a substantially inverted U-shaped pressing seal line 2a, 2b, 2c
To seal the opening 2. Then, the X-ray film 3 is sealed in the sealed flat bag, and the bag main body 1 is applied to the inner side of the teeth according to the above-mentioned usage, and X-ray photography is performed.
Using an injector 4 such as a syringe as shown by the chain line in (a), insert the tip 4a of the injector 4 from the opening 2 between the substantially parallel seal lines 2a and 2b, and connect the vertical seal line 2c. One bath solution is injected into the bag body 1 by piercing at the tip 4a, and
For about 0 seconds to 1 minute, squeeze the bag body 1
After the film 3 is brought into good contact with the film 3, the opening 2 is opened, the sealing wires 2a and 2b are peeled off, and the film 3 is taken out.

[0004]

As described above, it takes time and effort to inject a drug solution from a narrow entrance of a small bag body with an injector, and from a place where the injector 4 breaks through while injecting the bag body 1 with a finger. The chemical may leak and not only stain the fingertips, but also cause harm.

In addition, seal lines 2a, 2a
Since b and 2c have complicated shapes, there is a problem in that the seal strength varies and spontaneous peeling occurs due to strong impact or the like.

It is an object of the present invention to provide a package that does not require the injection of a chemical solution and does not leak the chemical solution during fixing of the phenomenon.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a chemical bag enclosing a chemical solution and an X-ray film are housed in a sealed flat bag body, and the chemical bag is attached to the flat bag body. It was made possible to burst by pressing from the outer surface.

[0008] It is preferable that one end of the flat bag main body is an opening, and a linear sealing line crossing the flat bag main body is provided inside the opening, and the opening is sealed with the sealing line. Further, it is preferable that the front and back sheets forming the flat bag main body outside the seal line are tabs that can be separated, and that the tab is pulled to peel off the seal line and open the opening.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, a package according to the present invention includes a flat bag main body 10 and a flat bag main body 1.
It comprises a chemical solution bag 20 and an X-ray film 30 sealed in the inside. The flat bag body 10 is formed by laminating a substantially rectangular front sheet 11 and a back sheet 12 made of a flexible synthetic resin sheet such as vinyl chloride, and forming three peripheral edges 10a, 10b, 10
c is heat-sealed (so-called three-way seal) and the opening 1
3, a sealing line 10d that crosses the flat bag main body 10 in a substantially straight line is formed, and the opening 13 is sealed.
Since the outside from the seal wire 10d is not joined,
The tabs 11a and 12a can be pinched by a finger, and when these are pulled in a direction away from each other, a sealing line 10d is formed.
Can be opened.

The chemical solution bag 20 has a flat bag shape like the flat bag body 10, and contains a single bath solution 21. This chemical solution bag 20 is made of a flexible synthetic resin film such as vinyl chloride and has a rectangular shape smaller in size than the bag body 10 as shown in FIG.
b and 20c are sealed (three-way seal), and after the chemical solution is injected,
A seal line 20 d is formed inside the opening 22 to form the opening 22.
Is sealed so that the chemical solution 21 does not leak. After the chemical bag 20 and the X-ray film 30 are inserted into the flat bag main body 10, a sealing line 10d of the flat bag main body 10 is formed outside the seal line 20d of the chemical bag 20 as shown by a chain line in FIG. At the same time as closing the opening 13 of the flat bag body 10,
The chemical solution bag 20 is also joined (sealed) to the inner surface of the flat bag body 10,
Do not move inside the flat bag body 10.

Next, how to use the above package will be described.

First, as described above, the package of the present invention is applied to the inside of a tooth to perform X-ray photography.
When the front and back surfaces of the flat bag main body 10 are sandwiched between fingers and pressed slightly, the liquid medicine bag 20 in the inside is ruptured, and the liquid medicine 21 is filled with the liquid medicine bag 2.
From 0, it flows into the flat bag body 10. The chemical solution bag 20 is pre-adjusted in strength or sealing strength so that the chemical solution bag or its seal portion is broken by an increase in the internal pressure of the chemical solution due to pressing. And the flat bag body 10 for about 30 seconds to 1 minute
The development and fixation of the X-ray film 30 are completed when the hand is removed. Therefore, when the tabs 11a and 12a are pulled in the direction in which the tabs 11a and 12a are separated from each other, the sealing line 10d is peeled off, and the opening 13 is opened.
The X-ray film 30 can be taken out.

The shape of the chemical bag 30 is not limited to a rectangular shape as shown in the figure, but may be any other shape such as an elliptical shape or an elliptical shape, which is particularly easy to burst.

[0014]

According to the present invention, as described above, the chemical solution bag which can be ruptured by pressing is stored together with the X-ray film in the flat bag body of the package, so that it is necessary to inject the chemical solution after X-ray photography. And the development and fixing can be performed with the hermetically sealed, so that the fingers and the like are not contaminated with the chemical solution.

In addition, since the sealing line at the opening may be linear, there is an advantage that the sealing strength is stable and no defective product is produced.
