Definitions
- the invention relates to a packaging for a dental X-ray film, which has a light-tight, two-surface light-protective cover that receives the dental X-ray film and a lead film that protects against X-rays.
- the invention further relates to a device for developing the dental X-ray film.
- the conventional dental X-ray films have hitherto been accommodated together with a lead foil, a separating cardboard and a surrounding black paper in a bag-like packaging made of plastic, so that they are light- and mouth-saliva-proof.
- the separation carton is arranged between the lead foil and the dental X-ray film in order to protect the dental X-ray film from contact with the lead film. Otherwise, this would create spots on the dental X-ray film.
- the black paper protects against the incidence of light.
- the exposed dental X-ray film If the exposed dental X-ray film is to be developed, it must first be removed from the packaging in a darkened room. It is difficult to remove the dental X-ray films, which are only 30 x 40 mm in size for adults and only 22 x 30 mm for children, in the dark; because the packaging is complex and designed differently and is not easy to open because it has to protect the film from incidence of light and from mouth moisture. Furthermore, when unpacking, care must be taken to free the dental X-ray film from the lead film, the separating cardboard and black paper, which is loosely located in the packaging. An automatic unpacking of the dental X-ray films is with the known packaging not possible because of their complex and complicated different design.
- the known packaging has not only the disadvantage that it can only be handled with great difficulty. They are also not optimal for reasons of environmental protection and the conservation of resources. Because there is a lead foil in every packaging, each time a dental X-ray film is unpacked, such a lead foil is generated as waste. For cost reasons, the lead foil is therefore made relatively thin-walled, but this has the disadvantage that it absorbs only 20-40% of the X-rays and therefore only offers incomplete protection against X-rays.
- the outer packaging is usually made of polyethylene and therefore, like the lead foil, must not be disposed of together with the separating cardboard and black paper. Most of the time, however, the entire packaging with the lead foil and the polyethylene part is thrown into the trash for convenience.
- the dental X-ray film is usually clipped onto the development frame at a corner. It is easy to cling to the image area so that part of the image content is lost.
- the subsequent development and fixing of the dental X-ray film is often not optimal with the known devices with regard to the movement and temperature of the baths. This often results in X-ray images of insufficient quality.
- the invention is based on the problem of developing packaging of the type mentioned at the outset which is particularly simple and, if desired, can also be removed automatically from the dental X-ray film. Furthermore, a device for developing a dental X-ray film initially contained in this package is to be created.
- the first-mentioned object is achieved according to the invention in that the light protection cover is arranged in an easy-to-open X-ray protection cover which enables the light protection cover to be removed and which at the same time contains the lead foil protecting against X-rays.
- the X-ray protective cover can first be opened in the light and the light protective cover can be removed from it. Unpacking the dental X-ray film from the light protection cover in a darkened room or that automatic unpacking of the dental X-ray film from this light protection sleeve is little trouble and requires little effort because this is only a very simple packaging. Due to the fact that, according to the invention, the light protection cover is accommodated in an X-ray protection cover, it is only necessary to provide a user with dental X-ray films packed in a simple light protection cover. The X-ray protective cover can be sterilized after use like all dental cutlery and can therefore be used again and again so that a dentist only needs to have several of them.
- the lead foil arranged in it does not represent any waste after the use of an X-ray protective cover. Therefore, it can be made thick enough at a reasonable cost to largely prevent the X-rays penetrating through the dental X-ray film during X-ray absorb. Since only the light protection envelope surrounding the dental X-ray film becomes waste when unpacking a dental X-ray film and this light protection envelope can consist of paper, the packaging according to the invention does not cause any disposal problems.
- a tear-open tab is formed on each of the cover areas on an edge common to the packaging, and the cover areas are easily connected to one another at their two edges running parallel to the edge with the respective tear-open tab.
- the second task namely the creation of a device for developing a dental X-ray film initially packaged in a light protection cover according to claim 2, which has a development container with a development frame below an input slot in which the dental X-ray film is to be inserted, is achieved according to the invention in that the development device above the input slot leading into the development container and in alignment therewith in an airlock body has an insertion shaft for the packaging with the dental X-ray film, which is open to an insertion side which is transverse to the plane of the direction of insertion of the dental X-ray film into the development container and is at right angles to the top of the development container, and in each of which a slot for receiving a tear-open tab of the packaging opens from opposite sides, these two slots simultaneously de r Entry side are open.
- the light protection cover can be pushed into the insertion shaft in daylight from the insertion side in such a way that the tear-open tabs protrude from the slots in opposite directions. Then it is only necessary to pull on the two tear-open tabs, whereby the light protection cover is torn open and the dental X-ray film falls through the insertion slot into the development frame.
- This device for opening light protection sleeves is advantageous regardless of whether it previously formed part of a package according to claim 1.
- This device according to the invention makes it unnecessary to set up a dark room or a darkened room. The loss of time that previously occurred due to the transport of the packaged dental X-ray film to the dark chamber and the laborious unpacking of the dental film there, its complicated handling during development and the transport of the developed dental film is also eliminated.
- the lock body When the light protection cover is torn open, the lock body is reliably light-tight without the lock body having to be elaborately designed if, according to another development of the invention, the lock body on the insertion side has a flap that covers the insertion shaft and the two slots in the closed state in a light-tight manner having.
- the light protection cover can protrude upwards out of the insertion shaft. Then you need a lower height for the lock body than the length of the dental X-ray film. However, there is a particularly secure light-tightness if, according to another development of the invention, the insertion shaft on the top of the lock body on the side facing away from the development container is closed.
- An alternative embodiment of the device for developing a dental X-ray film initially packaged in a package according to Claims 1 or 2, which has a development container with a development frame below an insertion slot in which the dental X-ray film is to be inserted, consists in that the development device is closed has on both sides of the input slot two drivable rollers which are arranged parallel to one another and are designed for connection to the tear-open tabs of the packaging. Even such a device no longer makes it necessary to unpack the dental X-ray film in the dark and place it in the development container; rather, the device, like the first-mentioned, can be used with light in the usual practice rooms.
- the device is particularly simple if, according to another development of the invention, one of the rollers can be driven by a handwheel and both rollers each have a gear or friction wheel, which are in engagement with one another.
- the x-ray film can be placed together with the development frame after its development in a water bath and a warm air chamber, so that it is particularly easy to handle if, according to another embodiment of the invention, the development frame is easily detachable below the input slot by means of a snap connection ⁇ is ordered.
- the invention permits numerous embodiments. To further clarify its basic principle, a packaging according to the invention and two development devices according to the invention are shown in the drawing and are described below. They show in her
- FIG. 3 shows a side view of the casing during its tearing open
- 4 shows a perspective view of a lid of a development container according to the invention
- FIG. 5 is a side view of the lid with a development frame
- FIG. 6 shows a perspective view of a second embodiment of a lid of the development container.
- the packaging shown in FIG. 1 has an outer X-ray protective cover 1, which is preferably made of polypropylene and must be waterproof.
- a lead film 2 which should be thick enough to form effective radiation protection for the patient during X-raying, is firmly connected to an inner wall surface of the X-ray protective cover 1.
- Inside the X-ray protective cover 1 there is a dental X-ray film 3 which is surrounded by a light protective cover 4.
- the X-ray protective cover 1 is designed on one side, for example, in such a way that it can be opened and closed again without being destroyed, in order to be able to remove the dental X-ray film 3 with the light protective cover 4 from it.
- FIG. 2 shows the light protection cover 4 from its broad side. Therefore, you can see a cover surface 5, behind which the dental X-ray film 3 is arranged. As seen in FIG. 2, behind the dental X-ray film 3 there is another cover surface 6, which can be seen in FIG. 3. A tear tab 7 is formed on the cover surface 5. As can be seen in FIG. 3, the cover surface 6 has a corresponding tear-open tab 8. If the tear-open tabs 7, 8 are pulled apart, as can be seen in FIG. 3, the cover surfaces 5, 6 are torn apart so that the dental X-ray film 3 comes free from the light protection cover 4 and falls out of it downwards.
- FIG. 4 shows in perspective a lid 9 of a developing device, which is placed on a partially illustrated developing container 10 from above and on which a lock body 11 is arranged.
- This lock body 11 has an insertion shaft 12, which is aligned with an input slot 13 in the cover 9.
- the insertion shaft 12 is open at the top, but also towards an insertion side 14 of the lock body 11.
- This insertion side 14 is oriented at right angles to the plane of the cover 9 and is located on a narrow side of the input slot 13.
- a slot 15, 16 leads from opposite sides into the insertion shaft 12. Both slots 15, 16 are also open towards the insertion side 14.
- a flap 17 shown open in FIG. 4 can be pivoted about a hinge axis 18, so that it lies light-tight against the insertion side 14 in the closed state.
- FIG. 5 shows that a development frame 19 is held on the underside of the cover 9 by a snap connection having two spring elements 20, 21. This development frame 19 is dimensioned such that a dental X-ray film 3 inserted over the lock body 11 slides against the lower end of the development frame 19.
- the input slot 13 is located in the cover 9 between two rollers 24, 25 each arranged in a cover recess 22, 23.
- the roller 24 can be rotated by means of a handwheel 26.
- Gears 27, 28 transmit this rotary movement to the other roller 25.
