Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to a monitor and a display component for a monitor. Background Technique

[0002] Magnetic resonance imaging examination can help doctors diagnose and evaluate various diseases and health conditions of patients. The time for a single magnetic resonance examination is usually 10 - 20 minutes, and some examinations even require half an hour or even one hour. During the magnetic resonance examination, doctors hope to monitor the patient's physiological parameters in real time to ensure the safety of the patient.

[0003] Since the monitoring device will be interfered by a strong magnetic field in the magnetic resonance room environment, which will cause problems of unstable operation. Therefore, the whole machine of the monitoring device needs to be shielded. Generally, the alarm lights used to implement the alarm function in the existing monitoring devices are set in conspicuous and not easily blocked positions such as the front panel of the monitor and around the display screen, so as to facilitate medical staff to obtain alarm information in time and make a quick response. However, the alarm light emitted from the inside of the machine will inevitably damage the overall shielding of the panel area around the display screen due to structural requirements, resulting in a poor shielding effect of the display component.

[0004] In addition, due to the difference in the working principles of the capacitive screen and the resistive screen, only the resistive screen with stronger anti-interference ability can be selected in the nuclear magnetic environment. However, due to the manufacturing process problems of the resistive screen, the resistive screen is relatively thicker than the capacitive screen. After being assembled with the liquid crystal display (LCD), there are defects that the overall viewing angle will become smaller on the basis of the original display screen, and there are also problems of magnetic shielding leakage in the assembly of the screen component. Content of the Utility Model

[0005] The utility model provides a monitor and a display component for a monitor to solve the problems raised in the background technique.

[0006] On the one hand, the present application provides a display component for a monitor, including a display component main body and a rotating component.

[0007] Further, the display component main body includes a rear shell, a screen component, a front shell, a cover plate, an alarm light board, a light guide column and an installation plug-in. Both the rear shell and the front shell are made of non-magnetic metal materials. The rear shell is also fixedly provided with an installation plug-in, and the installation plug-in is provided with a protruding part. The installation plug-in is made of non-magnetic metal material.

[0008] Further, the screen component includes an LCD display screen, a resistive screen and a shielding film; the shielding film has conductivity.

[0009] Further, the rotating assembly includes a non-magnetic metal cover plate, a rotating member, a first fixed sheet metal, and a second fixed sheet metal. The two ends of the rotating member are provided with protruding columns, and the first fixed sheet metal and the second fixed sheet metal are both provided with limiting grooves that are rotatably matched with the protruding columns. The number of the first fixed sheet metal and the second fixed sheet metal is two each.

[0010] Further, a first slot is opened on the non-magnetic metal cover plate, and the rotating member is fixed to the first slot by the two first fixed sheet metals and the two second fixed sheet metals. At this time, the protruding columns are rotatably matched with the limiting grooves so that the rotating member is rotatably connected to the first slot. The metal parts of the rotating member and the non-magnetic metal cover plate in contact with each other are in close contact to achieve good electrical connection, thereby ensuring a good shielding effect.

[0011] Further, a second slot is also opened on the rotating member. The second slot is matched with the protruding part of the mounting plug-in for placing the display component main body, so that the rotation angle of the display component main body can be adjusted as required to obtain the angle of the screen component. Thus, the problem of the overall visual angle becoming smaller due to the thickness of the resistive screen is solved.

[0012] Further, the alarm lamp board includes a solder mask area and a window area surrounding the solder mask area. The window area is a non-magnetic metal layer. Alarm lamps are provided at both ends of the solder mask area, and fixing holes are provided at both ends of the window area. The alarm lamp board can be selected as a PCB.

[0013] Further, the alarm lamp board is fixedly installed on the rear case through fasteners such as screws or bolts. For example, the alarm lamp board can be arranged on the upper side or the lower side of the rear case. On the rear case, at the position corresponding to the installation of the alarm lamp board, a partial area is hollowed out to install the light guide column. The light guide column is usually designed with a scattering structure, and the critical angle of the light guide column is random.

[0014] Further, the non-magnetic metal surface of the window area is connected to the complete non-magnetic metal plane inside the alarm lamp board (not shown in the figure) through a via design (less than millimeter level, not shown in the figure). The length of the alarm lamp board is longer than the area hollowed out on the display component main body for installing the light guide column. Therefore, it is ensured that the alarm lamps at both ends of the solder mask area are located below the non-magnetic metal of the rear case, and electrical signal transmission lines are arranged on the back of the alarm lamp board to minimize the interference of the magnetic field on the alarm lamps as much as possible.

[0015] Further, the warning light is welded to the warning light board by a welding method that emits light from the side. The light of the warning light first hits the light guide column, and is evenly scattered from the inside of the light guide column, which not only avoids the appearance of light spots and dark areas, but also enables users to see the warning light from different angles. This not only ensures that the requirements of the warning light can be met, but also guarantees the overall shielding effect of the display component body.

[0016] After the warning light board is fixedly installed on the rear case, a good electrical connection will be formed between the window area and the rear case, and the warning light board will be covered from the rear side of the rear case by the cover plate. Thus, even if a part of the rear case and / or the front case is hollowed out as a warning light light guide channel, the influence of this hollowed out area on the shielding effect can be reduced through the good electrical connection between the window area of the warning light board and the rear case, thereby solving the problem of the deterioration of the shielding effect of the display component.

[0017] It can be understood that the light emitted by the warning light can make the light evenly distributed in the entire light guide column after passing through the light guide column, avoiding the phenomenon of uneven brightness.

[0018] It can be understood that when assembling the screen component, the rear case is placed at the bottom, and then the LCD display screen, the resistive touch screen and the shielding film are assembled in sequence. Finally, the front case is covered above the shielding film, and the rear case and the front case are tightly assembled and fixed together by fasteners such as screws. This can make the shielding film form a good electrical connection with the front case, thereby wrapping the entire screen component inside, avoiding the penetration or leakage of the electromagnetic field, and solving the problem of the deterioration of the shielding effect of the display component.

[0019] On the other hand, the present application provides a monitor, and the monitor includes the display component body and the rotating component, that is, the display component body on the monitor is installed through the rotating component, thereby constituting the monitor of the present application. The monitor can provide guarantee for stably, reliably and real-time monitoring the physiological parameters of patients in the magnetic resonance room.

[0020] One of the above technical solutions has the following advantages or beneficial effects, and another of the above technical solutions has the following advantages or beneficial effects:

[0021] (1). An opening area surrounding the board and a solder mask area surrounded by it are designed on the front of the warning light board, and warning lights are placed at both ends of the solder mask area. In this way, the position of the warning lights is below the non-magnetic metal of the front panel, and all the electrical signals on the warning light board are routed from the back of the warning light board, minimizing the interference of the magnetic field on the warning lights as much as possible. At the same time, the warning lights are welded to the warning light board by a side-emitting welding method. The light of the warning lights first shines on the light guide column and is evenly scattered from the inside of the light guide column, which not only avoids the appearance of light spots and dark areas but also enables users to see the warning light from different angles. Through the above design, the requirements of the warning lights are ensured, and the overall shielding effect of the monitor display component is also guaranteed.

[0022] (2). The design of the rotating component of the present utility model enables the screen component to have an adjustable angle range of -5° to 30° relative to the vertical plane, allowing users to flexibly adjust the angle of the screen relative to themselves. At the same time, the part of the non-magnetic metal cover plate of the rotating component that comes into contact with the main body of the display component is non-magnetic metal. After pressing, they are in good contact with each other, ensuring the tightness of the metal conductor coupling and good electrical connection here, and preventing electromagnetic waves from leaking from the connection. Through the above design, the overall shielding effect of the monitor display component is guaranteed.

[0023] (3). Since the shielding film has conductivity, after the shielding film is pressed together with the display component, good electrical connection is ensured, eliminating the electromagnetic leakage gaps generated after the LCD display screen and the resistive touch screen in the display component are pressed together, and also ensuring the overall shielding effect of the monitor display component.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application.

[0031] Term explanation:

[0032] Solder mask: It is a special coating applied to the surface of the PCB, also known as solder resist ink, usually composed of raw materials such as phenolic resin, chloroethane, and curing agent, which prevents the copper on the PCB surface from oxidizing, defends against chemical erosion by substances such as acids and alkalis, protects the circuits, pads, and other important components on the PCB surface, and extends the service life of the PCB.

[0033] Figure 1 It is a schematic diagram of the alarm lamp board provided by the embodiment of the present application. The monitor and the display assembly for the monitor provided by the specific embodiment of the present application can be used in the magnetic resonance room environment, and the display assembly of the monitor includes an alarm lamp board 1, a rotating assembly 2, a screen assembly 3, and a display assembly body 4.

[0034] The alarm lamp board 1 includes a solder mask area 12 and an opening area 13 surrounding the solder mask area 12. The opening area 13 is a non-magnetic metal layer. Alarm lamps 11 are provided at both ends of the solder mask area 12, and fixing holes 14 are provided at both ends of the opening area 13. The alarm lamp board 1 can be selected as a Printed Circuit Board (PCB).

[0035] Figure 2 It is a three-dimensional structural schematic diagram of the display assembly body provided by the embodiment of the present application. The display assembly body 4 includes a rear shell 41, a front shell 42, a cover plate 43, a light guide column 44, and a mounting plug-in 45. The mounting plug-in 45 is made of non-magnetic metal material. The alarm lamp board 1 is fixedly connected to the rear shell 41 through fasteners such as screws or bolts, and the specific position can be flexibly selected according to actual needs. For example, the alarm lamp board 1 can be arranged on the upper side, lower side, left side, right side of the rear shell 41 or a combination thereof.

[0036] Figure 3 This is a schematic three-dimensional structure diagram of the rear case provided by the embodiment of the present application. On the rear case 41, at a corresponding position for installing the alarm lamp board 1, a partial area is hollowed out to install the light guide column 44. Of course, a partial area can also be hollowed out on the front case or a partial area can be hollowed out on both the rear case 41 and the front case 42 to install the light guide column 44. The light guide column 44 is usually designed with a scattering structure, and the surface of the light guide column is covered with random critical angles.

[0037] The window area 13 forms a good electrical connection with the rear case 41, and the alarm lamp board 1 is covered from the rear side of the rear case 41 by the cover plate 43. After adopting such a structure, even if a partial area of the rear case 41 or / and the front case 42 is hollowed out as the light guide channel for the alarm lamp, the influence of this hollowed-out area on the shielding effect can be reduced through the good electrical connection between the window area 13 of the alarm lamp board 1 and the rear case 41.

[0038] The non-magnetic metal surface of the window area 13 is connected to the complete non-magnetic metal plane inside the alarm lamp board 1 through a via design (less than millimeter level, Figure 1 not shown in the figure). The length of the alarm lamp board 1 is longer than the area hollowed out on the display component main body 4 for installing the light guide column 44. Therefore, it is ensured that the alarm lamps 11 at both ends of the solder mask area 12 are located under the non-magnetic metal of the rear case 41, and electrical signal transmission lines are arranged on the back of the alarm lamp board 1 to minimize the interference of the magnetic field on the alarm lamps 11. Figure 1 not shown in the figure). The alarm lamps 11 are welded to the alarm lamp board 1 by a side-emitting welding method. The light of the alarm lamps 11 first shines on the light guide column 44 and is evenly scattered from the inside of the light guide column 44. This not only avoids the appearance of light spots and dark areas, but also enables users to see the alarm light from different angles, which not only ensures the requirements of the alarm lamp but also guarantees the overall shielding effect of the display component main body.

[0039] Furthermore, the rear case 41 is also fixedly provided with an installation plug-in 45, and the installation plug-in 45 is provided with a protruding part.

[0040] The screen assembly 3 is composed of an LCD display screen 31, a resistive touch screen 32, and a shielding film 33, and the shielding film 33 has conductivity.

[0041]

[0042] ​It can be understood that when assembling the screen assembly 3, the rear shell 41 is placed at the bottommost, and then the LCD display screen 31, the resistive touch screen 32, and the shielding film 33 are assembled in sequence. Finally, the front shell 42 is covered above the shielding film 33, and the rear shell 41 and the front shell 42 are tightly assembled and fixed together by fasteners such as screws. Therefore, a good electrical connection is formed between the shielding film 33 and the front shell 42, thereby wrapping the entire screen assembly 3 inside, avoiding the penetration or leakage of electromagnetic fields.

[0043] Figure 4 The three-dimensional schematic diagram of the rotating assembly provided by the embodiment of the present application, the rotating assembly 2 includes a rotating member 21, a non-magnetic metal cover plate 22, a first fixed sheet metal 23, and a second fixed sheet metal 24. Convex columns 27 are provided at both ends of the rotating member 21, and limit grooves 28 that are rotatably matched with the convex columns 27 are provided on both the first fixed sheet metal 23 and the second fixed sheet metal 24. The number of the first fixed sheet metal 23 and the second fixed sheet metal 24 is two each.

[0044] A first slot 25 is opened on the non-magnetic metal cover plate 22, and the rotating member 21 is fixed to the first slot 25 by two pieces of the first fixed sheet metal 23 and two pieces of the second fixed sheet metal 24. At this time, the convex column 27 is rotatably matched with the limit groove 28 so that the rotating member 21 is rotatably connected to the first slot 25. The metal parts of the rotating member 21 and the non-magnetic metal cover plate 22 in contact with each other are in close contact to achieve a good electrical connection, thereby ensuring a good shielding effect.

[0045] Further, a second slot 26 is also opened on the rotating member 21. The second slot 26 cooperates with the protruding part of the mounting plug-in 45 for placing the display component main body 4, so that the rotation angle of the display component main body 4 can be adjusted as needed, enabling the screen assembly to have an adjustable angle range of -5° to 30° relative to the vertical plane.

[0046] Figure 5 The three-dimensional schematic diagram of the monitor provided by the embodiment of the present application. The display component main body 4 can be installed together by using the rotating assembly 2 to form the monitor of the present application. The monitor can meet the space requirements of the light alarm function and the shielding effect when used in a magnetic resonance room. It can also enable the user to adjust the relative angle between himself and the display screen, reduce the influence caused by the reduced viewing angle after the resistive touch screen is installed on the display screen, and avoid the internal circuit being interfered by external strong magnetic fields or the internal energy radiating out to affect the normal operation of the magnetic resonance equipment.

[0047] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
