Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a medical device with a rotatable display screen. Background Technology

[0002] Currently, most medical devices display medical data to users via screens, such as patient monitors. Users can monitor a patient's vital signs in real time through the displayed data. Therefore, the screens of medical devices need to provide clear data display in different clinical usage scenarios. For example, when medical devices are placed at a high position, such as on lamps, beds, or towers, external factors such as light may affect the user's ability to clearly read the medical data on the screen, leading to delays in diagnosis or misjudgments of the patient's vital signs, which could indirectly cause irreversible clinical accidents. Therefore, the screen's tilt angle needs to be adjustable. Alternatively, in clinical usage scenarios where users need to frequently move, the screen needs to be able to rotate to ensure clear reading of the medical data from different positions. However, because medical device screens are generally heavy, the strength of ordinary screws and other connectors is insufficient, leading to problems such as unstable screen fixation and the inability to maintain a certain rotation angle. Summary of the Invention

[0003] In view of this, this application provides a medical device aimed at solving the technical problem of insufficient strength of the fixing structure of the rotatable display screen of the medical device.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0053] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0054] The medical device provided in this application embodiment, based on the concept of improving the fixing structure strength of the rotatable display screen of the medical device, introduces a first hinge fixing plate and a second hinge fixing plate, which are fixed in a way that is not directly connected to the damping hinge, forming a sandwich fixing structure to ensure the fixing strength of the rotatable display screen. A detailed description follows.

[0055] It is understood that the illustrations in this application use a patient monitor as an example, and the medical device provided in this application can also be other medical devices with a rotatable display screen, which is not limited here.

[0056] This application provides a medical device; please refer to [link / reference]. Figure 1 and Figure 2The medical device includes a first mounting bracket 10, a second mounting bracket 20, a main unit 30, and a display screen 40. The display screen 40 is mounted on the first mounting bracket 10, and the second mounting bracket 20 is mounted on the main unit 30. It is understood that the display screen 40 and the first mounting bracket 10 can be separate structures requiring separate installation, or they can be an integrated structure; this is not limited here. Similarly, the second mounting bracket 20 and the main unit 30 can be separate structures requiring separate installation, or they can be an integrated structure; this is not limited here.

[0057] In some embodiments, please refer to Figures 3 to 6 The medical device also includes a damping hinge 50, which comprises a first fixing part 51, a second fixing part 52, and a damping pivot 53. The first fixing part 51 and the second fixing part 52 are rotatably connected via the damping pivot 53. By fixing the first mounting bracket 10 to the first fixing part 51 of the damping hinge 50 and the second mounting bracket 20 to the second fixing part 52 of the damping hinge 50, the relative rotation between the first fixing part 51 and the second fixing part 52 can cause the first mounting bracket 10 to rotate relative to the second mounting bracket 20, thereby causing the display screen 40 to rotate relative to the host 30. This allows the user to clearly see the data on the display screen from different angles or positions.

[0058] It should be noted that when the first fixing part 51 rotates relative to the second fixing part 52 to a preset angle, the first fixing part 51 and the second fixing part 52 can remain relatively fixed at the preset angle without the action of external force, so that the first mounting bracket 10 and the second mounting bracket 20 can remain relatively fixed at the preset angle, that is, the display screen 40 can remain stable relative to the host 30 at the preset angle, so that the user can easily read the data on the display screen 40.

[0059] In one embodiment, the display screen 40 of the medical device can be configured to rotate vertically, in which case the rotation axis of the damping shaft 53 is parallel to the plane where the bottom 23 of the medical device is located, the plane where the first mounting bracket 10 is located, and the plane where the second mounting bracket 20 is located, respectively. Please refer to [link / reference]. Figure 1 The display screen 40 of the medical device is positioned at a first preset angle, at which point the display screen 40 is substantially perpendicular to the bottom 23 of the medical device, and the display screen 40 is essentially in a vertical position, making it convenient for the user to view the display screen 40 at eye level to read data. For example, the first preset angle can be 0°. When the medical device is placed at a high position, such as on a lamp bed tower support, the display screen 40 can be adjusted downwards and rotated to a second preset angle. Please refer to [link to relevant documentation]. Figure 2At this time, the display screen 40 is offset from the vertical position by a certain downward angle, so that the user can clearly read the data when looking up at the display screen 40 of the medical device, reducing the influence of light and other external factors. For example, the second preset angle can be 5°, 10° or 15°, etc.

[0060] In another embodiment, the display screen 40 of the medical device can also be configured to rotate left and right, in which case the rotation axis of the damping shaft 53 is perpendicular to the plane of the bottom 23 of the medical device. For example, when there is only one display screen 40 around the patient to observe data, the left-right rotating display screen 40 allows the user to adjust the display screen 40 to clearly read the data regardless of which side of the patient they are on.

[0061] In some embodiments, please refer to Figure 3 and Figure 6 The medical device also includes a first hinge fixing plate 60 and a second hinge fixing plate 70. The first hinge fixing plate 60 fixes the first fixing part 51 and the first mounting bracket 10. The first fixing part 51 and the first hinge fixing plate 60 are respectively disposed on both sides of the first mounting bracket 10 to form a sandwich fixing structure to ensure the fixing strength of the first mounting bracket 10. The second hinge fixing plate 70 fixes the second fixing part 52 and the second mounting bracket 20. The second fixing part 52 and the second hinge fixing plate 70 are respectively disposed on both sides of the second mounting bracket 20 to form a sandwich fixing structure to ensure the fixing strength of the second mounting bracket 20.

[0062] In some embodiments, after the first fixing part 51 and the first hinge fixing plate 60 are respectively disposed on both sides of the first mounting bracket 10, the first fixing part 51, the first mounting bracket 10 and the first hinge fixing plate 60 are connected together by the first connector 80; after the second fixing part 52 and the second hinge fixing plate 70 are respectively disposed on both sides of the second mounting bracket 20, the second fixing part 52, the second mounting bracket 20 and the second hinge fixing plate 70 are connected together by the second connector 90. Compared with directly fixing the first fixing part 51 and the first mounting bracket 10, the second fixing part 52 and the second mounting bracket 20 together with the connector, the introduction of the first hinge fixing plate 60 and the second hinge fixing plate 70 can increase the force-bearing area and improve the fixing strength, so that the first mounting bracket 10 can remain stable during the rotation of the second mounting bracket 20 and will not easily fall off.

[0063] In some embodiments, for a more robust connection, please refer to Figure 4 and Figure 6The first fixing part 51 is provided with a first mounting post 56, the first mounting bracket 10 is provided with a first through hole, and the first hinge fixing plate 60 is provided with a second through hole. During installation, the first mounting post 56 passes through the first through hole, and the first connector 80 passes through the second through hole and simultaneously passes through the first through hole to connect with the first mounting post 56. The second fixing part 52 is provided with a second mounting post 57, the second mounting bracket 20 is provided with a third through hole, and the second hinge fixing plate 70 is provided with a fourth through hole. The second mounting post 57 passes through the third through hole, and the second connector 90 passes through the fourth through hole and simultaneously passes through the third through hole to connect with the second mounting post 57. By introducing the first mounting post 56 and the second mounting post 57, the connection strength between the first fixing part 51, the first mounting bracket 10 and the first hinge fixing plate 60, and between the second fixing part 52, the second mounting bracket 20 and the second hinge fixing plate 70 can be further strengthened.

[0064] It is understood that the first connector 80 and / or the second connector 90 can be threaded connectors, such as screws, bolts or studs, or snap-fit ​​connectors, as long as they can serve the purpose of connection and fixation, and there is no limitation here.

[0065] In some embodiments, the rotation axis of the damping shaft 53 is parallel to the plane where the first fixing part 51 is located and the plane where the second fixing part 52 is located, respectively, and the damping shaft 53 is disposed between the first fixing part 51 and the second fixing part 52. (See also...) Figure 3 and Figure 4 When the display screen 40 is basically in a vertical position, the planes containing the first fixing part 51, the first mounting bracket 10, the first hinge fixing plate 60, the second fixing part 52, the second mounting bracket 20, and the second hinge fixing plate 70 are basically parallel. In one embodiment, to make the structure more compact, the first hinge fixing plate 60 and the second fixing part 52 are both disposed between the first mounting bracket 10 and the second mounting bracket 20.

[0066] In one embodiment, the damping shaft 53 is disposed in the middle of the first fixing part 51, and / or, the damping shaft 53 is disposed in the middle of the second fixing part 52. In this case, the lever arm of the first mounting bracket 10 when rotating relative to the second mounting bracket 20 is smaller, and the strength is higher.

[0067] In another embodiment, the damping shaft 53 may also be disposed at the end of the first fixing part 51 and the second fixing part 52.

[0068] In some embodiments, please refer to Figure 4The damping hinge 50 further includes a first connecting portion 54 connected to the first fixing portion 51, the first connecting portion 54 extending from the first fixing portion 51 toward the second fixing portion 52, and the first connecting portion 54 being used to connect the damping pivot 53; the damping hinge 50 also includes a second connecting portion 55 connected to the second fixing portion 52, the second connecting portion 55 extending from the second fixing portion 52 toward the first fixing portion 51, and the second connecting portion 55 being used to connect the damping pivot 53. Preferably, the first connecting portion 54 may be perpendicular to the first fixing portion 51, and the second connecting portion 55 may be perpendicular to the second fixing portion 52.

[0069] In some embodiments, the medical device further includes a bottom 23, and the second mounting bracket 20 includes a top frame 21 opposite to the bottom 23 and two side frames 22 adjacent to the top frame 21, the two side frames 22 each including two outer sidewalls 221.

[0070] In one embodiment, please refer to Figure 3 and Figure 5 There are two damping hinges 50, which are symmetrically arranged on the two side frames 22. The rotation axes of the two damping hinges 50 are located on a straight line, so that the first mounting bracket 10 can be more stable during the rotation of the second mounting bracket 20.

[0071] In another embodiment, the second mounting bracket 20 further includes a bottom frame opposite to the top frame 21, and the damping hinge 50 can also be disposed on the bottom frame, enabling the first mounting bracket 10 to rotate vertically relative to the second mounting bracket 20. It is understood that the placement of the damping hinge is not limited, as long as it enables the first mounting bracket 10 to rotate relative to the second mounting bracket 20, and no restrictions are imposed here.

[0072] In some embodiments, the first mounting bracket 10 includes a mounting portion for mounting the second mounting bracket 20. The mounting portion includes an inner sidewall 11, which mates with an outer sidewall 221 during installation. In one embodiment, the outer sidewall 221 of the second mounting bracket 20 can be inserted into the inner sidewall 11 of the first mounting bracket 10. It is understood that the mounting portion can be hollow or recessed, as long as it can be used to mount the second mounting bracket 20; no limitation is imposed here.

[0073] In some embodiments, in order to control the movement gap when the first mounting bracket 10 rotates relative to the second mounting bracket 20, a positioning post 110 is provided on one of the first mounting bracket 10 and the second mounting bracket 20, and a positioning hole 120 that cooperates with the positioning post 110 is provided on the other. When the first mounting bracket 10 rotates relative to the second mounting bracket 20, the hole wall of the positioning hole 120 is movably engaged with the outer wall of the positioning post 110 to limit the first mounting bracket 10. That is, when the first mounting bracket 10 rotates relative to the second mounting bracket 20, the positioning post 110 always needs to be inserted into the positioning hole 120, so that the first mounting bracket 10 is basically unable to move in all directions within its plane, thereby ensuring that the movement gap between the first mounting bracket 10 and the second mounting bracket 20 is consistent.

[0074] In some embodiments, the positioning post 110 or positioning hole 120 can be disposed on the top frame 21 or on the two side frames 22. In one embodiment, when the positioning post 110 or positioning hole 120 is disposed on the side frame 22 and the damping hinge 50 is also disposed on the side frame 22, the positioning post 110 or positioning hole 120 is located between the damping pivot 53 and the top frame 21, which can minimize the mating gap between the first mounting bracket 10 and the second mounting bracket 20.

[0075] In one embodiment, please refer to Figures 7 to 10 Positioning pins 110 are provided on the first mounting bracket 10, and positioning holes 120 are provided on the second mounting bracket 20. There are two positioning pins 110 and two positioning holes 120. The two positioning holes 120 are respectively located on the two side frames 22. Using two positioning pins 110 and two positioning holes 120 allows for more precise control of the movement gap between the first mounting bracket 10 and the second mounting bracket 20. Preferably, the positioning hole 120 is located between the damping shaft 53 and the top frame 21. If the positioning hole 120 is closer to the top frame 21, it can effectively reduce the mating gap at the top between the first mounting bracket 10 and the second mounting bracket 20, ensuring consistent gap dimensions during rotation.

[0076] In some embodiments, positioning plates 130 may be provided on the first mounting bracket 10 and the second mounting bracket 20 respectively to limit the movement of the first mounting bracket 10 along the linear axis of rotation of the damping rotation axis 53 when it rotates relative to the second mounting bracket 20. It is understood that the positioning plates 130 may be provided on the top frame 21 of the second mounting bracket 20 or on the two side frames 22, as long as they can limit the movement of the first mounting bracket 10 along the linear axis of rotation of the damping rotation axis 53 when it rotates relative to the second mounting bracket 20, and there is no limitation here.

[0077] In one embodiment, please refer to Figure 7 , Figure 8 , Figure 11and Figure 12 The positioning piece 130 includes a first positioning piece 131 disposed on the first mounting bracket 10 and a second positioning piece 132 disposed on the second mounting bracket 20. The outer side wall 221 of the second mounting bracket 20 and the second positioning piece 132 are located between the inner side wall 11 and the first positioning piece 131.

[0078] In some embodiments, in order to better limit the movement of the first mounting bracket 10 along the linear axis of rotation of the damping pivot 53 when it rotates relative to the second mounting bracket 20, the outer side wall 221 is further provided with a positioning boss 140 on the side facing the inner side wall 11.

[0079] When the first mounting bracket 10 and the second mounting bracket 20 are fitted together, there are gaps on both sides. Since the first mounting bracket 10 has a first positioning piece 131 and the second mounting bracket 20 has a second positioning piece 132, and the second mounting bracket 20 has positioning bosses 140 on both sides, when dimensional tolerances fluctuate, the inner frame size of the mounting portion of the first mounting bracket 10 decreases, and the outer frame size of the second mounting bracket 20 increases. The inner wall 11 of the first mounting bracket 10 will inevitably contact the positioning bosses 140 of the second mounting bracket 20, causing elastic deformation of either the first mounting bracket 10 or the second mounting bracket 20. Because the force on the positioning bosses 140 on both sides is consistent, the gaps on both sides can be kept relatively uniform. When the dimensional tolerances fluctuate, the inner frame size of the mounting portion of the first mounting bracket 10 decreases, and the outer frame size of the second mounting bracket 20 increases. Due to tolerance fluctuations, the inner frame size of the mounting portion of the first mounting bracket 10 increases, while the outer frame size of the second mounting bracket 20 decreases. The first positioning piece 131 of the first mounting bracket 10 will inevitably contact the second positioning piece 132 of the second mounting bracket 20, causing elastic deformation of either the first mounting bracket 10 or the second mounting bracket 20. Since the force on the first positioning piece 131 and the second positioning piece 132 on both sides is consistent, the gap on both sides can also be kept relatively uniform. This allows the movement of the first mounting bracket 10 along the rotation axis of the damping shaft 53 to be restricted in various situations when it rotates relative to the second mounting bracket 20, thus better controlling the movement gap when the first mounting bracket 10 rotates relative to the second mounting bracket 20.

[0080] In some embodiments, a limiting structure may also be provided to limit the angle of rotation of the first mounting bracket 10 relative to the second mounting bracket 20. For example, see [link to relevant documentation]. Figure 9 The second mounting bracket 20 is provided with a first limiting structure 150 on the upper side of the straight line where the rotation axis of the damping shaft 53 is located, which is used to limit the upward rotation angle of the first mounting bracket 10 relative to the second mounting bracket 20; the second mounting bracket 20 is provided with a second limiting structure 160 on the lower side of the straight line where the rotation axis of the damping shaft 53 is located, which is used to limit the downward rotation angle of the first mounting bracket 10 relative to the second mounting bracket 20.

[0081] In one embodiment, when the first mounting bracket 10 rotates to contact the first limiting structure 150, the display screen 40 of the medical device is basically in a vertical position. Since the vertical position is generally the conventional position when the medical device is in use, preferably, a magnet can also be provided at the first limiting structure 150 so that when the first mounting bracket 10 rotates to contact the first limiting structure 150, the display screen 40 of the medical device can be kept more stable in the vertical position through magnetic attraction.

[0082] In some embodiments, to improve the user's operational experience when adjusting the rotation of the display screen 40 of the medical device relative to the host 30, an audible feedback structure may be added. Specifically, an audible feedback plate 170 is provided on one of the first mounting bracket 10 and the second mounting bracket 20, and a trigger structure 180 that cooperates with the audible feedback plate 170 is provided on the other. When the first mounting bracket 10 rotates relative to the second mounting bracket 20 to a preset angle, the audible feedback plate 170 can contact the trigger structure 180 to emit a sound, thereby prompting the user to rotate to the correct position.

[0083] It is understandable that the number of times the first mounting bracket 10 needs to rotate relative to the second mounting bracket 20 to a preset angle for sound feedback is related to the number of trigger structures 180, and the preset angle at which the first mounting bracket 10 rotates relative to the second mounting bracket 20 to provide sound feedback is related to the position of the trigger structure 180.

[0084] In some embodiments, the sound feedback piece 170 is fixed to the first mounting bracket 10 or the second mounting bracket 20 by the feedback piece fixing structure 190.

[0085] In one embodiment, please refer to Figure 5 , Figure 13 and Figure 14The sound feedback piece 170 is disposed on the first mounting bracket 10. The feedback piece fixing structure 190 includes a first feedback piece fixing structure 191 and a second feedback piece fixing structure 192. The sound feedback piece 170 is fixed to the first feedback piece fixing structure 191 through the second feedback piece fixing structure 192, and then mounted on the first mounting bracket 10 through the first feedback piece fixing structure 191. Two trigger structures 180 are disposed on the second mounting bracket 20. When the display screen 40 of the medical device is at a first preset angle, that is, when the first mounting bracket 10 rotates relative to the second mounting bracket 20 to the first preset angle, one of the trigger structures 180 will actuate the sound feedback piece 170 to trigger a sound; when the display screen 40 of the medical device is at a second preset angle, that is, when the first mounting bracket 10 rotates relative to the second mounting bracket 20 to the second preset angle, the other trigger structure 180 will actuate the sound feedback piece 170 to trigger a sound, thereby achieving sound feedback when the display screen 40 of the medical device rotates to two commonly used positions, improving the user's operating experience.

[0086] The medical device provided in this application embodiment, by fixing the first mounting bracket 10 to the first fixing part 51 of the damping hinge 50 and the second mounting bracket 20 to the second fixing part 52 of the damping hinge 50, can drive the first mounting bracket 10 to rotate relative to the second mounting bracket 20 through the relative rotation between the first fixing part 51 and the second fixing part 52, thereby driving the display screen 40 to rotate relative to the host 30. At the same time, the introduction of the first hinge fixing plate 60 to fix the first fixing part 51 and the first mounting bracket 10, and the second hinge fixing plate 70 to fix the second fixing part 52 and the second mounting bracket 20, can increase the force-bearing area and improve the fixing strength. In addition, by setting the first fixing part 51 and the first hinge fixing plate 60 on both sides of the first mounting bracket 10, and setting the second fixing part 52 and the second hinge fixing plate 70 on both sides of the second mounting bracket 20, a sandwich fixing structure is formed to ensure the fixing strength of the first mounting bracket 10 and the second mounting bracket 20.

[0087] In addition, the medical device provided in this application embodiment is also provided with a positioning plate 130, a cooperating positioning post 110 and a positioning hole 120 to control the movement gap when the first mounting bracket 10 rotates relative to the second mounting bracket 20; and provides sound feedback when the display screen 40 rotates to a specific position through a cooperating sound feedback plate 170 and a trigger structure 180, thereby improving the user's operating quality experience.
