Description

Technical Field

[0001] This invention relates to the field of medical display technology, and more specifically to a dual-screen foldable medical display. Background Technology

[0002] Currently, dual-monitor configurations are increasingly widely used in medical equipment and various professional scenarios. In medical diagnosis, doctors often need to view high-precision images such as CT and MRI on one monitor while simultaneously reviewing electronic medical records or color ultrasound reports on another. In the operating room, the surgeon needs to simultaneously monitor endoscopic images, patient vital signs, and surgical navigation information. In intensive care and emergency settings, medical staff need to simultaneously monitor vital sign waveforms and bedside images. The need for simultaneous dual-screen display is also prevalent in remote consultations and medical training.

[0003] In the aforementioned application scenarios, existing technologies typically employ two independent individual displays, each mounted on its own stand. However, each display requires separate rotation and adjustment, which is cumbersome and time-consuming, impacting operational efficiency. Furthermore, the exposed power and signal cables of both displays affect aesthetics and cleanliness, and are prone to tangling and pulling, posing safety hazards. Additionally, the separate installation of two displays is complex and occupies significant operating space, which is particularly disadvantageous in space-constrained environments such as operating rooms and emergency rooms. Moreover, they cannot be folded for storage when not in use, and prolonged exposure makes them susceptible to damage from accidental bumps and knocks. Currently, no effective solution has been proposed to address these issues. Summary of the Invention

[0004] To address some or all of the problems existing in the prior art, the present invention provides a dual-screen foldable medical display, including an upper display and a lower display. The upper display and the lower display are hinged together by a pivot mechanism. The upper display can rotate and swing relative to the lower display along the pivot mechanism. The lower display has a cable exit hole at one end away from the pivot mechanism. The dual-screen foldable medical display also includes a cable guide frame. The cable guide frame is a hollow structure with two parallel hinge shafts arranged on it. One hinge shaft is hinged to the upper display at both ends, and the other hinge shaft is hinged to the lower display at both ends. The hinge shaft is a hollow tubular structure, and the inner hole of the hinge shaft is connected to the inner cavity of the cable guide frame.

[0005] As a further improvement of the present invention, the rotating shaft mechanism includes a rotating shaft fixing block and a connecting seat. Two fixed shafts are arranged in parallel on the rotating shaft fixing block. The connecting seat is provided with a mounting hole. The fixed shafts pass through the mounting hole, and the connecting seat can rotate and swing on the fixed shafts. The connecting seat is connected to the upper display or the lower display.

[0006] As a further improvement of the present invention, a limiting shim is sleeved on the fixed shaft, a limiting block is provided on the outer peripheral side wall of the limiting shim, and two limiting bosses are provided on the connecting seat, and the limiting block can abut against the limiting bosses.

[0007] As a further improvement of the present invention, a positioning shim is sleeved on the fixed shaft. The positioning shim can slide axially on the fixed shaft. The positioning shim abuts against the end face of the connecting seat. A positioning protrusion is provided on the end face of the positioning shim near the connecting seat. A positioning groove that matches the positioning protrusion is provided on the end face of the connecting seat near the positioning shim.

[0008] As a further improvement of the present invention, an arched gasket is sleeved on the fixed shaft, and the arched gasket abuts against the side of the positioning gasket away from the connecting seat.

[0009] As a further improvement of the present invention, a fixing nut is sleeved on the fixing shaft, the fixing nut is threadedly connected to the fixing shaft, and the fixing nut abuts against the side of the arched washer away from the positioning washer.

[0010] As a further improvement of the present invention, there are three arched gaskets, and the three arched gaskets are arranged side by side on the fixed shaft.

[0011] As a further improvement of the present invention, each fixed shaft is provided with two connecting seats, and the two connecting seats are symmetrically distributed on both sides of the rotating shaft fixing block.

[0012] As a further improvement of the present invention, the outlet hole is provided with a rotatable outlet shaft, and the outlet shaft is a hollow structure.

[0013] As a further improvement of the present invention, the upper display rotates and swings relative to the lower display along the rotating shaft mechanism in an angle range of 0-180°.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates the upper and lower displays into one unit via a hinge mechanism, enabling simultaneous folding of both screens. This simple and quick operation improves the work efficiency of medical staff. When not in use, both displays can be folded for storage, significantly reducing space requirements and facilitating transportation and storage. The folded screens are also effectively protected from damage caused by accidental bumps. Furthermore, by using a hollow cable management frame and a hollow tubular hinge shaft, the cable passes sequentially from the upper display through the inner hole of the hinge shaft, the inner cavity of the cable management frame, and the inner hole of the hinge shaft in the lower display before entering the lower display and finally exiting through the cable outlet, achieving fully internal cable routing. The cables are completely hidden inside the displays and the cable management frame, resulting in a neat and aesthetically pleasing appearance, facilitating cleaning and disinfection, and effectively avoiding the risks of cable tangling, pulling, and damage, thus eliminating safety hazards.

[0015] Furthermore, this invention achieves precise limiting of the display screen's rotation angle through the cooperation of the limiting shims and limiting bosses in the rotating shaft mechanism, preventing damage caused by excessive rotation. The engagement between the positioning protrusions on the positioning shims and the positioning grooves on the connecting seat, along with the mutual abutment of multiple arched shims, allows users to clearly judge whether the rotation is complete by feel during operation, improving the user experience. A rotatable hollow cable exit shaft is provided on the cable exit hole, allowing the cable's exit direction to be adjusted as needed, further facilitating cable routing. Attached Figure Description

Detailed Implementation

[0018] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figures 1 to 6 As shown, a dual-screen foldable medical display includes an upper display 100 and a lower display 200. The upper display 100 and the lower display 200 are hinged together by a pivot mechanism 500, allowing the upper display 100 to rotate and swing relative to the lower display 200 along the pivot mechanism 500. Through the hinge action of the pivot mechanism 500, the upper display 100 and the lower display 200 are connected as a whole, realizing dual-screen linkage. Users only need to perform one operation to adjust the relative angle of the two displays simultaneously, avoiding the cumbersome operation of adjusting two independent displays separately in the prior art. The preferred rotation and swing angle range of the upper display 100 relative to the lower display 200 along the pivot mechanism 500 is 0-180°, allowing the two displays to gradually unfold from a fully folded state (0°) to a fully flat state (180°), meeting the viewing angle requirements in different usage scenarios.

[0022] In this embodiment, there are two rotating shaft mechanisms 500, and the two rotating shaft mechanisms 500 are symmetrically distributed along the center line of the lower display 200. In other embodiments, the number of rotating shaft mechanisms 500 can be any other number.

[0023] The lower display 200 has a cable exit hole at the end furthest from the hinge mechanism 500 for various signal cables, power cables, etc., to exit. The cable exit hole is located at the bottom of the lower display 200, which facilitates the cables to extend uniformly from the bottom of the display and connect to external devices or power supplies, making the overall wiring neat and orderly.

[0024] To facilitate cable routing, a rotatable cable exit shaft 300 with a hollow structure is installed on the cable exit hole. After the cable passes through the interior of the lower monitor 200, it extends to the outside via the hollow cable exit shaft 300. Because the cable exit shaft 300 can rotate within the cable exit hole, the cable's exit direction can be freely adjusted according to actual usage needs, preventing excessive bending at the exit point, protecting the cable from damage, and also facilitating on-site cable wiring and installation of the monitor.

[0025] like Figure 1 , Figure 2 As shown, the dual-screen foldable medical display also includes a wire guide frame 400, which is located at the hinge position between the upper display 100 and the lower display 200. The wire guide frame 400 is a hollow structure, and two hinge shafts 401 are arranged parallel to each other on the wire guide frame 400. One hinge shaft 401 is hinged to the upper display 100 at both ends, and the other hinge shaft 401 is hinged to the lower display 200 at both ends. In this embodiment, the hinge shaft 401 and the wire guide frame 400 are integrally formed. The hinge shaft 401 is a hollow tubular structure, and the inner hole of the hinge shaft 401 is connected to the inner cavity of the wire guide frame 400. During assembly, the cable of the upper display 100 can pass through the inner hole of the hinge shaft 401 hinged to the upper display 100 into the wire guide frame 400, then extend into the lower display 200 from the inner hole of the hinge shaft 401 hinged to the lower display 200, and then extend out through the cable exit shaft 300. The above structure enables fully internal cabling between the upper display 100 and the lower display 200. The cables are completely hidden within the hinge shaft 401, the wire frame 400, and the display itself, resulting in a neat and aesthetically pleasing appearance that facilitates cleaning and disinfection in a medical environment. Simultaneously, the cables are effectively protected, avoiding the risk of damage caused by tangling or pulling when exposed, thus eliminating safety hazards.

[0026] like Figures 3 to 6As shown, the rotating shaft mechanism 500 includes a rotating shaft fixing block 1 and a connecting seat 2. Two fixed shafts 3 are arranged parallel to each other on the rotating shaft fixing block 1. The connecting seat 2 has mounting holes 21 through which the fixed shafts 3 pass, and the connecting seat 2 can rotate and swing on the fixed shafts 3. The connecting seat 2 is used to fixally connect to the upper display 100 or the lower display 200. Through the cooperation of the fixed shafts 3 and the mounting holes 21, the connecting seat 2 can rotate freely around the fixed shafts 3, thereby causing the upper display 100 or the lower display 200 connected to the connecting seat 2 to swing relative to the rotating shaft fixing block 1. The two fixed shafts 3 are arranged in parallel, allowing the upper display 100 and the lower display 200 to rotate around their respective fixed shafts 3, realizing independent adjustment and coordinated folding of the relative angles of the two displays.

[0027] To limit the rotational travel of the connecting seat 2, a limiting washer 4 is fitted onto the fixed shaft 3. A limiting block 41 is provided on the outer peripheral sidewall of the limiting washer 4. The connecting seat 2 has two limiting protrusions 22, which abut against the limiting protrusions 22. The cooperation of these two components limits the rotational travel of the connecting seat 2 on the fixed shaft 3. When the connecting seat 2 rotates with the display around the fixed shaft 3, the limiting protrusions 22 rotate together. When one of the limiting protrusions 22 rotates to abut against the limiting block 41 on the limiting washer 4, further rotation of the connecting seat 2 in that direction is prevented. During reverse rotation, when the other limiting protrusion 22 rotates to abut against the limiting block 41 on the limiting washer 4, further rotation of the connecting seat 2 in that direction is prevented. By using the limit stop 41 in conjunction with the two limit protrusions 22, the rotation angle of the connector 2 and the display is limited within a preset range, preventing damage to the display screen or cable breakage due to excessive rotation, thus ensuring the safety and lifespan of the equipment.

[0028] To position the display screen in its fully open and fully closed states, a positioning shim 5 is fitted onto the fixed shaft 3. The positioning shim 5 can slide axially on the fixed shaft 3 and abuts against the end face of the connecting seat 2. A positioning protrusion 51 is provided on the end face of the positioning shim 5 near the connecting seat 2, and a positioning groove 23 that matches the positioning protrusion 51 is provided on the end face of the connecting seat 2 near the positioning shim 5. Through the engagement of the positioning protrusion 51 and the positioning groove 23, the user can determine by touch whether the screen has been fully opened or fully closed, thus achieving the positioning function. When the connecting seat 2 is rotated to its fully open or fully closed state, the positioning protrusion 51 on the positioning shim 5 will engage with the positioning groove 23 on the end face of the connecting seat 2, producing a clear tactile engagement accompanied by a slight clicking sound. The user can thus determine whether the display screen is fully open or fully closed without visual confirmation, making operation more convenient and precise.

[0029] To ensure the display screen can be fixed at any angle, an arched washer 6 is fitted onto the fixed shaft 3. The arched washer 6 abuts against the side of the positioning washer 5 away from the connecting seat 2. When the connecting seat 2 is rotated, the end face of the connecting seat 2 presses against the positioning protrusion 51 on the positioning washer 5, causing the positioning washer 5 to slide axially on the fixed shaft 3. The positioning washer 5 then presses against the arched washer 6, causing it to deform. At this time, the positioning protrusion 51 can slide out of the positioning groove 23 and onto the end face of the connecting seat 2. The arched deformation allowance of the arched washer 6 provides room for the axial movement of the positioning washer 5. Specifically, when the user rotates the connecting seat 2, the end face of the connecting seat 2 pushes the positioning washer 5 to move axially along the fixed shaft 3, and the positioning washer 5 then presses against the arched washer 6. The arched washer 6 undergoes elastic deformation under force (the arch is flattened), providing space for the axial movement of the positioning washer 5, allowing the positioning protrusion 51 to disengage from the positioning groove 23. When the connecting seat 2 rotates until the positioning protrusion 51 aligns with the positioning groove 23, the arched gasket 6 returns to its original shape, pushing the positioning gasket 5 towards the connecting seat 2, and the positioning protrusion 51 re-engages into the next positioning groove 23. The arched gasket 6 ensures smooth positioning and provides a distinct tactile feedback.

[0030] A fixing nut 7 is fitted onto the fixing shaft 3, and the fixing nut 7 is threadedly connected to the fixing shaft 3. The fixing nut 7 abuts against the side of the arched washer 6 away from the positioning washer 5. The fixing nut 7 is fixed to the end of the fixing shaft 3 by the threaded connection, which presses the limiting washer 4, the positioning washer 5 and the arched washer 6 onto the fixing shaft 3 in sequence, preventing the washer from falling off the fixing shaft 3. At the same time, by adjusting the tightness of the fixing nut 7, the preload between the washer can be adjusted, thereby adjusting the damping feel during rotation.

[0031] Furthermore, the arched washer 6 remains compressed under the locking action of the fixing nut 7, and its arched structure generates a continuous axial elastic force. This elastic force is transmitted to the end face of the connecting seat 2 through the positioning washer 5, generating positive pressure between the connecting seat 2 and the positioning washer 5, between the positioning washer 5 and the limiting washer 4, and between other adjacent contact surfaces, thereby forming a frictional resistance torque. When the user stops rotating, this frictional resistance torque is sufficient to balance the torque generated by the weight of the upper display 100 or the lower display 200, allowing the display to stop stably at any rotation angle without swinging or falling. In other words, in addition to providing the deformation margin required for the axial movement of the positioning washer 5, the arched washer 6 also acts as a friction damping element, using the continuous friction generated by its elastic force to provide a uniform damping effect for the entire rotating shaft mechanism 500, ensuring that the display can be hovered and positioned at any angle within the range of 0 to 180°, allowing medical personnel to flexibly adjust the viewing angle in different usage scenarios without additional locking operations.

[0032] In this embodiment, there are three arched pads 6, which are arranged side-by-side on the fixed shaft 3. The side-by-side arrangement of the three arched pads 6 provides greater elastic deformation and more stable elastic recovery force, ensuring that the positioning pad 5 maintains good positioning effect and operational feel even after repeated use. Simultaneously, the combined use of multiple arched pads 6 effectively distributes the force, preventing fatigue failure of individual pads due to long-term use, extending the service life of the rotating shaft mechanism 500, and ensuring the reliability and durability of the display during frequent opening and closing. Furthermore, the superposition of the three arched pads 6 generates greater axial elastic force, further enhancing the friction damping effect, making the display more stable and reliable at any angle, maintaining good support even when the display is large and heavy. In other embodiments, the number of arched pads 6 can be any other number.

[0033] In this embodiment, each fixed shaft 3 is provided with two connecting seats 2, and the two connecting seats 2 are symmetrically distributed on both sides of the rotating shaft fixing block 1. The two connecting seats 2 are respectively connected to the upper display 100 or the lower display 200, so that the rotating shaft mechanism 500 and the corresponding display have two connection fixing points. The structure is symmetrical and the force is balanced, which ensures the stability and synchronization of the display screen during the rotation process.

[0034] Working principle: In use, the user can unfold the upper display 100 and lower display 200 to a suitable angle via the rotating mechanism 500. The upper display 100 and lower display 200 rotate relative to each other via the connecting seat 2 around two fixed shafts 3 on the rotating fixing block 1. During rotation, the limiting block 41 on the limiting pad 4 cooperates with the limiting boss 22 on the mounting base to limit the rotation angle within the range of 0-180°, preventing excessive rotation. Simultaneously, the positioning protrusion 51 on the positioning pad 5 cooperates with the positioning groove 23 on the end face of the connecting seat 2, creating a tactile engagement when fully closed or fully open, helping the user determine if the rotation is complete. The arched pad 6 provides space for the axial movement of the positioning pad 5 through elastic deformation, ensuring smooth positioning.

[0035] When not in use or during transport, users can rotate and fold the upper display 100 and the lower display 200 to a fully closed state via the hinge mechanism 500, which greatly reduces the space occupied by the display and makes it easy to store and transport. At the same time, the screens fit together after folding, preventing the screens from being damaged by accidental bumps.

[0036] In summary, the present invention realizes dual-screen linked folding through the rotating shaft mechanism 500, with simple and quick operation; full internal wiring is achieved through the wire passing frame 400 and the hollow hinge shaft 401, which results in a neat and aesthetic appearance and eliminates potential safety hazards; through the cooperation of the limiting, positioning and damping structures on the rotating shaft mechanism 500, precise angle control and good operation handfeel are provided; space saving and screen protection are realized through the foldable design. The technical problems in the prior art that dual displays are installed separately, the operation is cumbersome, the cables are messy, the space occupation is large and the displays cannot be folded for storage are solved, and the present invention can be applied to medical scenarios such as operating rooms, intensive care units, emergency rooms, image diagnosis rooms and remote consultation centers.

[0037] The specific embodiments described above are preferred embodiments of the present invention, and are not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to the specific embodiments, and all equivalent changes made in accordance with the present invention shall fall within the protection scope of the present invention.
