Abstract

(57) [Summary] [Purpose] Regarding the film for intraoral radiography, AIDS,
The purpose is to prevent nosocomial infections such as hepatitis C and MRSA. [Structure] In a film for intraoral X-ray photography in which a film material is covered with a photo-sensitivity case, the photo-sensitivity case is sealed with a vinyl chloride resin film.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a film for intraoral radiography used in a dental clinic or the like.

[0002]

[Prior art]

 Conventionally, an intraoral X-ray film used in a dental clinic or the like is composed of a film main body (photosensitive paper) 1, a paper 2 for protecting the film main body 1, and a lead plate 3 as shown in FIGS. 3 and 4, for example. The film material 4 is covered by a vinyl chloride resin envelope-shaped photosensitive case 5 whose inner surface is black.

[0003]

[Problems to be solved by the device]

 However, since the X-ray film is mounted in the patient's mouth for imaging, saliva, blood, or other suspended matter in the mouth of the patient adheres to the surface of the photosensitivity-preventing case 5.

The photographed film for X-ray photography is developed by taking out the film main body 1 by tearing off the photo-sensing case 5 covering the film material 4 with an operator's hand.

Therefore, the worker's hand directly touches the saliva, blood, and other suspended matter in the mouth of the patient adhering to the surface of the photosensitization prevention case 5, and thus AIDS (acquired immunodeficiency) Syndrome), hepatitis C, MRSA, etc. may cause nosocomial infection.

The present invention has been made to solve such a problem, and its purpose is to prevent AIDS and hepatitis C even if the operator's hand directly touches the photosensitive case of the film for X-ray photography. To provide a film for intraoral radiography that does not cause nosocomial infections such as MRSA.

[0007]

[Means for Solving the Problems]

 The present invention is characterized in that, in an intraoral X-ray photographing film in which a film material is covered with a photosensitization case, the photosensitization case is sealed with a sheet through which X-rays easily pass.

[0008]

[Action]

 After X-ray photography, remove the sheet on the surface to which the patient's saliva, blood, and other floating substances in the mouth adhere, that is, the sheet that easily transmits X-rays, by using tweezers, etc. When the case is directly touched by the operator, it does not touch the patient's saliva, blood, or other suspended matter in the mouth.

Therefore, no more nosocomial infections such as AIDS, hepatitis C, and MRSA can be prevented.

[0010]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of a film for intraoral radiography according to the present invention.

In FIG. 1, reference numeral 1 denotes a film main body which is photosensitive paper, and the outside of the film main body 1 is protected by a black paper 2. A lead plate 3 is provided on the upper surface of the black paper 2 so that the X-rays are appropriately irradiated.

The film main body 1, the paper 2 and the lead plate 3 constitute a film material 4. The film material 4, which is composed of the film main body 1, the paper 2 and the lead plate 3, is covered with an envelope-shaped anti-photosensitivity case 5 made of vinyl chloride resin, the inner surface of which is blackened, and is protected from photosensitivity. Further, the anti-photosensitive case 5 is further sealed with a sheet through which X-rays are more easily transmitted, for example, a transparent vinyl chloride resin film 6.

According to such an intraoral X-ray photography film, since the anti-photosensitivity case 5 is sealed with the vinyl chloride resin film 6, the saliva, blood, or other air in the mouth of the patient is suspended during photography. The substance adheres to the surface of the vinyl chloride resin film 6 that seals the photosensitive case 5.

Therefore, after photographing, by removing the vinyl chloride resin film 6 that seals the exposure prevention case 5 of the X-ray photography film with tweezers or the like, an operator can remove the exposure prevention case 5 of the X-ray photography film. Direct hand contact will not touch the patient's saliva, blood, or other floating material in the mouth.

Of course, since the vinyl chloride resin film 6 that seals the light-proofing case 5 is a sheet through which X-rays easily pass, it does not affect the image. Then, the envelope-shaped lip portion 7 of the exposure prevention case 5 is torn and the film main body 1 is taken out and developed.

[0016] Therefore, nosocomial infections such as AIDS, hepatitis C and MRSA will not occur. Incidentally, as the sheet for sealing the photosensitive case, other than the vinyl chloride resin film, other resin sheets which easily transmit X-rays can be used.

[0017]

[Effect of device]

 As described above, according to the present invention, AIDS (acquired immunodeficiency syndrome), hepatitis C, MRSA, etc. can be obtained even if the operator's hand directly touches the photosensitive case of the film for X-ray photography. It has a remarkable effect that it does not cause nosocomial infection of.
