X-ray film observation and retention reader

Abstract

This invention discloses an X-ray film observation and storage reader, comprising a housing, a backlight panel, a general magnifying glass, a local magnifying glass, and a film scanning strip. By extending or retracting the backlight panel closer to or further away from the magnifying glass, the magnification of the lenses can be adjusted, assisting doctors in detecting subtle problems in finer areas of the film. Furthermore, stacking two lenses can achieve double magnification, enabling free localized magnification. The film scanning strip can scan and archive the film, primarily addressing the difficulty of collecting and archiving information from patients diagnosed at other hospitals and then visiting a different hospital for their first visit.

Description

Technical Field

[0001] This invention relates to the field of radiographic imaging technology, and more particularly to an X-ray film observation and retention reader. Background Technology

[0002] Imaging technology has not only improved the depth of examination within the human body and increased diagnostic accuracy, but it also enables targeted treatment of certain diseases. This has greatly expanded the application scope of imaging in clinical work and made it a crucial pillar of medical practice. In medicine, X-rays, as the earliest and most widely used examination method in clinical practice, are commonly used for human examinations and disease diagnosis. Together with emerging radiological examinations such as CT and MRI, they formed the new discipline of diagnostic radiology and laid the foundation for medical imaging. To this day, diagnostic radiology remains a major component of medical imaging and is widely used.

[0003] The Gray filter converts an image to grayscale. The Invert filter flips all the visual properties of an object, including color, saturation, and brightness values. The Xray filter makes the object reflect its outline and brightens those outlines, which is the so-called X-ray image. X-rays penetrate and irradiate the image, and are often used in medical treatment.

[0004] Existing X-ray observation devices have a simple structure and function. Doctors usually fix the X-ray film with clamps on the light box panel and read the film on the surface of the light panel. This makes it difficult to achieve free local magnification of the X-ray film, which may cause some fine structures in the patient's body to be overlooked, resulting in missed diagnosis and misdiagnosis of the disease.

[0005] Meanwhile, given the trend towards paperless office practices, each hospital has its own independent medical office system, making it impossible to share patient examination information across hospitals. Therefore, imaging data from patients visiting other hospitals can only be used for clinical observation, and it is difficult to retain the data. Furthermore, since clinical research requires comparing complete patient imaging data, the incomplete retention of imaging data in many cases also adds considerable difficulty to research work. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an X-ray observation and storage reader that can freely magnify X-ray images locally to help doctors discover subtle problems and can record and archive patients' X-ray images.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] An X-ray film observation and retention reader, characterized in that it includes:

[0009] The box has a receiving cavity with an open front side;

[0010] The backlight panel is placed vertically inside the cabinet and can be moved back and forth and locked using a telescopic mechanism;

[0011] The overall magnifying glass can cover the front of the receiving cavity;

[0012] A partial magnifying glass is mounted on a housing in front of the backlight panel and can move horizontally and vertically within a vertical plane via an adjustment mechanism; and

[0013] The film scanning strip is used to scan the X-ray film placed on the backlight and transmit the scanning information to the memory.

[0014] A further technical solution is that the telescopic mechanism is located on the back of the backlight panel, and includes:

[0015] Two sets of linkage rods are respectively installed on the opposite side walls of the housing. Each set of linkage rods includes two connecting rods, which are rotatably crossed at the middle by a pin.

[0016] In each set of linkages, the two rear linkages are fixed at the ends and can slide up and down to be fixed to the housing, while the two front linkages are movable at the ends and can slide up and down to be fixed to the back of the backlight panel; and

[0017] The drive unit is used to synchronously adjust and lock the included angle between the two connecting rods in the two sets of linkage rods.

[0018] A further technical solution is that the driving unit includes:

[0019] Two drive rods, each with its two ends rotatably connected to the fixed ends of two linkage rods on the same side, and threaded holes coaxially opened on the two drive rods, with the threads in the two threaded holes rotating in opposite directions;

[0020] The screw is vertically mounted, with its two ends threaded into the threaded holes of the upper and lower drive rods; and

[0021] A drive motor is connected to one end of the screw and is used to drive the screw to rotate.

[0022] A further technical solution is that the adjustment mechanism includes:

[0023] Two longitudinal guide rails are fixed to the left and right sides of the housing, respectively;

[0024] Two vertical sliders are respectively slidably connected to two vertical guide rails; and

[0025] The transverse guide rail is fixed at both ends to two longitudinal sliders;

[0026] The local magnifying glass is slidably mounted on a horizontal guide rail.

[0027] A further technical solution is that the transverse guide rail has two rails, the distance between the two transverse guide rails is located in the same vertical plane, and the same local magnifying lens is slidably mounted on the two transverse guide rails.

[0028] A further technical solution is that the longitudinal guide rail and the longitudinal slider are electrically driven or manually driven.

[0029] A further technical solution is that both ends of the film scanning strip are fixed to the longitudinal sliding block.

[0030] A further technical solution is that neither the film scanning strip nor the local magnifying glass protrudes from the front of the housing.

[0031] A further technical solution is that the overall magnifying glass is rotatably connected to the housing via a hinge.

[0032] A further technical solution is that the backlight panel matches the cross-sectional shape of the housing cavity.

[0033] The beneficial effects of adopting the above technical solution are as follows:

[0034] This X-ray film viewing and storage reader allows for magnification adjustment by extending or retracting the backlight panel closer to or further from the magnifying lens. This helps doctors detect subtle problems in finer areas of the film. Furthermore, stacking two lenses can achieve double the magnification, enabling localized magnification. The film scanning strip allows for scanning and archiving of films, primarily addressing the challenge of recording and archiving information for patients who were diagnosed at other hospitals and are now visiting a different hospital for their first visit.

[0037] Figure 2 This is a schematic diagram of the telescopic mechanism in the X-ray film observation and retention reader. Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] like Figure 1 and Figure 2 As shown, the X-ray film observation and retention reader includes a housing 10, a backlight panel 20, a general magnifying glass 30, a partial magnifying glass 40, and a film scanning strip 50. The backlight panel 20 is a commonly used X-ray film observation plate, and the film scanning strip 50 is also an existing scanning device.

[0041] In the X-ray film viewing and storage reader, the housing 10 has a receiving cavity with an open front side. A backlight panel 20 is vertically placed inside the housing 10, and its cross-sectional shape matches that of the receiving cavity. The backlight panel 20 can move back and forth within the housing 10 and lock itself using a telescopic mechanism. A general-purpose magnifying glass 30 covers the front of the receiving cavity and is rotatably connected to the housing 10 via a hinge, forming the front cover of the housing 10 and allowing it to be opened to hold the X-ray film. A partial magnifying glass 40 is located on the housing 10 in front of the backlight panel 20, between the general-purpose magnifying glass 30 and the backlight panel 20. The partial magnifying glass 40 can move laterally and longitudinally within the vertical plane using an adjustment mechanism to move to any position to achieve superimposed magnification of any part of the X-ray film. A film scanning strip 50 is used to scan the X-ray film placed on the backlight panel 20 and transmit the scanning information to a memory.

[0042] The telescopic mechanism is located on the back of the backlight panel 20 and includes two sets of linkage rods 61 and a drive unit.

[0043] Two sets of linkage rods 61 are respectively disposed on opposite side walls of the housing 10. Each set of linkage rods 61 includes two connecting rods, which are rotatably crossed by a pin in the middle. In each set of linkage rods 61, the ends of the two rear connecting rods are fixed ends 611 and can be slidably fixed to the housing 10, while the ends of the two front connecting rods are movable ends 612 and can be slidably fixed to the back of the backlight panel 20.

[0044] The drive unit is used to synchronously adjust and lock the included angle between two connecting rods in the two sets of linkage rods 61, so as to realize the forward and backward displacement of the movable end 612 of the linkage rod 61. The drive unit includes two drive rods 62, a screw 63 and a drive motor 64.

[0045] Two drive rods 62 are arranged vertically, and both ends of each drive rod 62 are rotatably connected to the fixed end 611 of the two linkage rods 61 on the same side. Threaded holes are coaxially formed on the two drive rods 62, with the threads in the two holes rotating in opposite directions. A screw 63 is vertically arranged, and both ends are threaded into the threaded holes of the two drive rods 62. A drive motor 64 is connected to one end of the screw 63 and is used to drive the screw 63 to rotate.

[0046] The drive motor 64 drives the screw 63 to rotate, causing the two drive rods 62 to move relative to each other or away from each other. This causes the two fixed ends 611 of a set of linkage rods 61 to move closer or further away from each other in the vertical direction along the slide groove, thereby driving the movable belt to generate displacement in the vertical and forward and backward directions, realizing the forward and backward movement and locking of the backlight panel 20.

[0047] The adjustment mechanism includes two longitudinal guide rails 71, two longitudinal sliders 72, and a transverse guide rail 73.

[0048] Two vertical guide rails 71 are vertically arranged and fixed on the left and right sides of the housing 10, respectively. Two vertical sliders 72 are slidably connected to the two vertical guide rails 71. The vertical guide rails 71 and the vertical sliders 72 are electrically driven or manually driven.

[0049] The two ends of the horizontal guide rail 73 are fixed to two vertical sliders 72, and the local magnifying lens 40 is slidably mounted on the horizontal guide rail 73. In order to maintain the smooth sliding of the local magnifying lens 40, two horizontal guide rails 73 can be set, with the distance between the two horizontal guide rails 73 located in the same vertical plane. The local magnifying lens 40 is slidably mounted on the two horizontal guide rails 73, which can effectively prevent the local magnifying lens 40 from deflecting.

[0050] The two ends of the film scanning strip 50 are fixed on the vertical sliding block 72, so as to realize the up and down movement of the film scanning strip 50 and realize the scanning of the entire X-ray film.

[0051] Neither the film scanning strip 50 nor the local magnifying glass 40 protrudes from the front of the housing 10, allowing the overall magnifying glass 30 to be laid flat.

[0052] When using this X-ray film observation and retention reader, the X-ray film to be viewed is placed in front of the backlight plate 20 and supported by the bottom plate of the housing 10. The X-ray film is sandwiched between the backlight plate 20 and the transverse guide rail 73, ensuring the stability of the X-ray film placement.

[0053] By extending or retracting the backlight panel 20 towards or away from the magnifying glass, the magnification of the lens can be adjusted, allowing doctors to detect subtle problems in finer areas of the film. Furthermore, stacking two lenses can achieve double the magnification, enabling free localized magnification. The film scanning strip 50 can scan and archive film images, primarily addressing the difficulty of collecting and archiving information from patients diagnosed at other hospitals and then visiting a different hospital for their first visit.

[0054] The above are merely preferred embodiments of the present invention. Any simple modifications, variations, and equivalent substitutions made by any person based on the content of the present invention shall fall within the protection scope of the present invention.
