Description
PORTABLE X-RAY FILM VIEWING APPARATUS
FIELD OF THE INVENTION
The present invention relates to portable X-ray viewers. More particularly, the present invention relates to a hand held apparatus for viewing X-ray dental films.
BACKGROUND OF THE INVENTION
In the medical and dental profession, it is required to observe and study X-rays. Presently, the common methods of studying such X-rays, is to have the X-ray illuminated on either a large, bulky viewer that is fixed to the wall or to attach it to an illuminated X-ray board. Such methods suffer from an inadequacy as it is impossible to hold and study X-rays while performing certain medical or dental procedures due to the size of existing viewers. To overcome this problem, a variety of different types of hand-held X-ray film viewers have been proposed over the last 40 years, some of which are presented as follows:
US Patent No. 4140377 describes a viewer which is especially adapted for viewing dental X-ray films taken of the mouth of a patient. The viewer is provided with a throat extending inwardly from the front thereof which vertically divides the housing into upper and lower sections. A display screen is provided on the front of the upper section of the housing with a light compartment for a light source on the side thereof, and a mirror is located in the lower section of the housing.
US Patent No. 4194635 describes an X-ray film grip or sheet support member, adapted to cooperate with a sheet support surface such as the lighted face of an X-ray film viewer. X-ray The film grip or sheet support member includes an elongated hollow framed element having a longitudinally extending slot formed therein facing the sheet support surface.
US Patent No. 4454669 describes a portable, easy to use photographic viewer for use particularly by medical and dental professionals. The viewer is light
weight and includes a light source, a photographic imaging screen, clip to retain the photographic slides or negatives in position and a support for maintaining the viewer in any desirable position.
US Patent No. 5274691 describes a device for developing and fixing a dental radiography plate includes a casing of flexible, impermeable material which is sealed around its entire perimeter and has first and second compartments interconnected by a flat duct. The first compartment contains a radiographic plate and the second compartment contains a sachet of a liquid for processing the plate. The sachet is adapted to release the liquid when its pressure exceeds a predetermined value as a result of the compression of the sachet.
US Patent No. 7404266 describes a portable x-ray viewer that is configured as a clipboard. The clipboard configuration makes the portable x-ray viewer easy to handle by doctors and other medical personnel. Since the viewer is portable, the number of required x-ray viewers in a doctor's office or a medical facility is greatly reduced, thus reducing the overall cost. In addition, the portable x-ray viewer is provided with an automatic control for controlling the viewer.
While different types of hand-held X-ray film viewers have been proposed in the past, they require developing, fixing and washing the X-ray films prior to viewing, which takes time until the wet film dries. Moreover, if the x-ray is to be viewed before it is completely dry, while still wet with fixing solution there is the problem of fixing solution dripping from the X-ray film, making it unfeasable to transfer the film quickly from the developing/fixing container(s) into a portable viewing apparatus. This is a particular disadvantage in dental practice, where much time is wasted waiting for the X-ray film to dry prior to transferring it into a viewer.
thus, it is an aim of the present invention is to provide a portable, simple and easy to use viewing apparatus designed to receive wet X-ray films transferred directly from the developing/fixing container(s), thus shortening significantly the time between taking the x-ray and viewing it.

Fig. 1 is a perspective view of a portable viewing apparatus in accordance with one embodiment of the present invention; and
Fig. 2 is a perspective view of a portable viewing apparatus in accordance with another embodiment of the present invention.
DETAILED DESCRIPTION OF THE FIGURES
Referring now to Fig. 1 there is shown a portable viewing apparatus 10 in accordance with the present invention. Portable viewing apparatus 10 comprises a box like housing 12 having a top side 14, a bottom side (not shown) to which is attached a gripping handle 16, an open back side 18 from which extends a light box 20, a front side 22 which has an aperture in which is placed a window, preferably a magnifying lens 23, a left side 24 and a right side (not shown).
A flap door 26 is connected hingedly to the edge of the bottom side and exposes the interior of the housing 12 when open. An x-ray film holding tray 28 having an extended transparent back wall 30 and a handle 31, is placed into position in the interior of the housing 12 by sliding the upper edge 32 of the back wall 30 of tray 28 into the channel 34 of the top side 14 and sliding the holding tray 28 into a channel 38 in the bottom side of housing 12. The x-ray holding tray 28 comprises a trough 40 containing an absorbing material 42, such as cotton, tissues or paper towels. Retaining means such as clips 44 are suspended from the top of the back wall 30 for holding wet x-ray film 46. Excess fixing solution that drips from the film is absorbed by the absorbing material 42. Lights 48 in the light box 20 illuminate the x-ray film 46 which is viewed through the magnifying glass 23.
Portable viewing apparatus 10 has the advantage over existing hand-held X-ray viewers in that it enables a quick transfer of the X-ray films from a developing/fixing container(s) into the holding tray 28 and into the portable viewing apparatus 10 while still wet without liquid spatter and/or spillage of corrosive fixing solution. This saves valuable time in that one does not have to wash the x-ray film and wait until it stops dripping.
Portable viewing apparatus 10 preferably comes with a base 50 for receiving the handle 16 and holding the apparatus when not using it. The apparatus 10 includes batteries 47 which may be long lasting and/or rechargeable, and may be contained in the handle 16 while the base 50 may be a charger for the batteries 47.
In accordance with this invention the portable viewing apparatus may contain more than one x-ray holding tray that can hold a number of X-ray films at the same time. Alternatively, the tray may be large enough so that a number of retaining means, such as clips, can be attached to the rear wall to hold several X-ray films at the same time.
The front wall of the portable viewing apparatus 10 may comprise a large magnifying lens to enable viewing several X-ray films at the same time. An alternative possibility for viewing multiple x-ray films is to provide a single small magnifying lens and means for moving the lens in the X and/or Y direction, possibly by sliding it on tracks from one side of the front wall to another and/or up and down to the desired position. This will enable viewing multiple x-ray films suspended in the viewer in sequence.
In accordance with the present invention, the rear wall of the X-ray holding tray may be made of a transparent material or has an opening to allow the passage of light to the X-ray film.
Instead of the flap door 26, the housing 12 may have a sliding door that slides along the edges of the top and the bottom sides to reveal the interior of housing 12 and to enable inserting and removing the X-ray holding tray.
In accordance with the present invention, portable viewing apparatus 10 may be constructed from polymers, metal, wood or a combination thereof.
Referring now to Fig. 2, there is shown a perspective view of a portable viewing apparatus 60 in accordance with another embodiment of the present invention. Portable viewing apparatus 60 is similar to portable viewing apparatus 10 with the exception that in portable viewing apparatus 60 the holding tray 64 is sufficiently large so that when inserted into box-like housing 62, the side wall 66 (a portion of side wall 66 is missing in Fig. 2 so that the viewer can see the interior of tray 64) of holding tray 64 seals the side opening 68 of box-like housing 62 (i.e., the side wall 66 of holding tray 64 replaces door 26 of portable viewing apparatus 10).
