[0025] According to an exemplary embodiment of the present invention, a medical device is provided.

[0026] Figure 1 1 is a schematic diagram showing a medical device 1000 according to Embodiment 1 of the present invention. The medical device 1000 is a multifunctional device that can be configured according to different medical needs, for example, a cart or an ultrasound device. Figure 1 As shown, the medical device 1000 mainly includes a display 100, an operation panel 200, a column 300, and a movable mechanism 400 ( Figure 1 ), the main machine 500 and the casters 600.

[0027] The display 100 is used to intuitively display the patient's physiological data, medical images, and device operation interface. The display 100 is connected to the operation panel 200, and can be embedded, suspended, or angle-adjustable, etc., in a manner known in the art to adapt to different usage scenarios and user perspectives. The operation panel 200 is the main interface for users to set up the device, select functions, and display data, and includes an upper component and a base.

[0028] The column 300 is disposed below the operation panel 200 , and the display 100 and the operation panel 200 are connected to the host 500 via the column 300 .

[0029] The host 500 is equipped with various electronic components configured to realize medical detection or diagnosis functions, including but not limited to circuit boards, various electronic components, cables, etc. At the same time, it is also equipped with various mechanical components (including but not limited to bases, support frames, pins and housings, etc.) and any other required components.

[0030] In addition, in order to facilitate the movement of the medical device 1000, Figure 1In the exemplary embodiment shown, a moving unit such as casters 600 is also installed at the bottom of the host 500, so that the medical device 1000 can be easily pushed and pulled. However, when the medical device 1000 is used in a fixed position, the casters 600 and other components may not be installed.

[0031] In addition, the display 100, the host 500, the caster 600, etc. can adopt structures known in the art. The connection between the display 100 and the operation panel 200 and the connection between the host 500 and the caster 600 can also adopt connection methods known in the art, which will not be repeated here.

[0032] also, Figure 1 The movable mechanism 400, which is not shown in the figure, is an important mechanical structure in the medical device, which allows the user to adjust the operation panel 200 as needed, thereby improving the comfort and efficiency of operation. The movable mechanism 400, which is a characteristic part involved in this exemplary embodiment, will be described in detail below.

[0033] Figure 2 2 is a schematic diagram showing the base 201 of the operation panel 200 according to the first embodiment of the present invention, showing a state where the upper components of the operation panel 200 are removed. Figure 2 As shown, the operation panel 200 has a base 201. In this example, a series of mechanisms related to the movement of the operation panel 200 provided on the base 201 are collectively referred to as a moving mechanism 400.

[0034] In this embodiment, the movable mechanism 400 includes a rotating part 410, and the rotating part 410 is used to drive the operation panel 200 to rotate, so that the user can operate or adjust it when using it. The rotating part 410 includes a first switch 411 and a protrusion 412. Among them, the first switch 411 is set on the base 201, and it has at least two working states, namely an open state and a locked state. When the first switch 411 is turned on and in the open state, the operation panel 200 is allowed to be operated and rotated. When the first switch 411 is in the locked state, the operation panel 200 is locked and cannot rotate.

[0035] The protrusion 412 is provided on the base 201, and when the first switch 411 is in a locked state, the protrusion 412 contacts the outer side of the first switch 411 to limit the first switch 411 from further rotating. In the present embodiment, a case where a protrusion 412 is provided is shown, but it is not limited thereto. In some embodiments, a plurality of protrusions may be provided as required. In addition, in the present example, the protrusion 412 is provided in a block shape with a trapezoidal cross section, but it is not limited thereto, and it may be provided in any possible shape as long as it can effectively limit its further rotating movement when the first switch 411 is in a locked state. In addition, the material of the protrusion 412 is provided to ensure that the protrusion 412 maintains the stability of its shape and function in long-term use, such as hard plastic, composite material, etc. In some embodiments, the surface of the protrusion 412 may also be specially treated, such as coating, texturing, etc., to improve the wear resistance of the protrusion 412, etc.

[0036] By providing the protrusion 412, when the first switch 411 is locked, the presence of the protrusion 412 can prevent the first switch 411 from further rotating due to external force or misoperation, and can reliably keep the first switch 411 in an appropriate position, thereby ensuring the stability and safety of the operation panel 200. In addition, the provision of the protrusion 412 also reduces the wear of the first switch 411 caused by excessive rotation or misoperation, and improves the durability and maintenance cycle of the entire rotating part 410.

[0037] Figure 3a It is a partial schematic diagram showing the base 201 when the first switch 411 involved in the first embodiment of the present invention is in the on state. Figure 3b It is a partial schematic diagram showing the base 201 when the first switch 411 involved in the first embodiment of the present invention is in a locked state. Figure 3a and Figure 3b Yes Figure 2 An enlarged view obtained by enlarging the portion indicated by the dotted circle in FIG.

[0038] like Figure 3a and Figure 3bAs shown, a top plate 301 is provided at the top of the column 300, and the top plate 301 is exposed to the upper part of the base through the opening of the base 201. The top plate 301 is fixed to the top of the column 300 by fasteners such as screws, but in some embodiments, it can also be formed as a whole with the column 300. In addition, a groove g1 is formed at a predetermined position on the circumference of the top plate 301 for locking the first switch 411. The size and size of the groove g1 are set to match the shape of the first switch 411 to ensure a tight fit and stable locking. In contrast, the first switch 411 is configured to be inserted and locked in the groove g1. In this embodiment, the first switch 411 is configured to be hook-shaped, but is not limited thereto, and can be set to any possible shape as long as it can interact with the groove g1 to achieve locking.

[0039] In addition, at least a portion of the side surface of the first switch 411 that contacts the groove g1 is provided with a groove g2. In this embodiment, the groove g2 serves as an oil storage tank. Figure 3b As shown, in the first switch 411, a vertical strip groove is opened from top to bottom on the side in contact with the groove g1. Lubricating oil can be stored in the groove g2, and overflow when the first switch 411 reciprocates between the open state and the locked state, thereby directly acting on the contact surface between the first switch 411 and the groove g1. By setting the groove g2 as an oil storage tank, it is ensured that an appropriate amount of lubricating oil overflows during the movement of the first switch 411, thereby reducing wear and improving the smoothness of movement, and improving the service life and reliability of the first switch 411. At the same time, maintenance personnel can directly add lubricating oil to the oil storage tank, avoiding the risk of lubricating oil leakage and overflow, and realizing efficient and clean lubrication maintenance. It can be understood that Figure 3b The groove g2 is exemplarily shown on the side of the first switch 411 , but the groove g2 can also be arranged on the side of the groove g1 .

[0040] In addition, the rotating part 410 further includes a first rotating shaft 413 disposed on the base 201, which serves as a rotation center of the first switch 411. Figure 3a and Figure 3b As shown, one end of the first switch 411 is connected to the first rotating shaft 413, and moves in a direction parallel to the base 301 via the first rotating shaft 413, so as to Figure 3a The open state shown is the same as Figure 3b Toggles between the lock states shown. Figure 3b As shown, when the first switch 411 is in the locked state, the other end of the first switch 411 is inserted into the groove g1. The first switch 411 and the first rotating shaft 413 can be connected in a manner known in the art, as long as the connection is firm and the rotation is smooth.

[0041] In addition, in some embodiments, a sleeve is provided on the outer periphery of the first rotating shaft 413. The sleeve is made of self-lubricating material, such as a copper sleeve, etc., to reduce friction and wear of the first rotating shaft 413 during movement, thereby improving the smoothness of the reciprocating motion of the first switch 411. In addition, the sleeve, as a protective layer, can prevent the first rotating shaft 413 from directly contacting the external environment, reduce the possibility of corrosion and pollution, and extend the service life of the rotating shaft.

[0042] In addition, the rotating part 410 further includes a reset element 414 disposed on the base 201. In this exemplary embodiment, the reset element 414 is configured as a tension spring. Figure 3a and Figure 3b As shown, one end of the reset element 414 is connected to the base 201, and the other end is connected to the first switch 411. The reset element 414 provides a reset force for the first switch 411 to the above-mentioned locked state. Specifically, when the first switch 411 is opened by an external force, Figure 3a When the first switch 411 is in the open state as shown in FIG. 1 , the tension spring as the reset element 414 is stretched. When the external force is released, the tension spring generates a contraction force to pull the first switch 411 back to Figure 3b Locked state as shown.

[0043] In some embodiments, a torsion spring can also be used as the reset element 414. Compared with a tension spring, a torsion spring stores and releases energy by twisting. Therefore, when the reset element 414 is a torsion spring, one end of the reset element 414 is connected to the base 201, and the other end is connected to the first rotating shaft 413. When the first switch 411 is opened by an external force, the reset element 414 is in a state of being locked. Figure 3a When the torsion spring 414 is in the open state as shown in the figure, it is twisted and stores torsion energy. When the external force is released, the torsion energy of the torsion spring restores the torsion spring to the initial state, thereby pushing the first rotating shaft 413 to rotate and pulling the first switch 411 back to the closed state. Figure 3b Locked state as shown.

[0044] By providing a reset element in the rotating part, an automatic reset function can be achieved, thereby ensuring that the medical device remains stable in a non-operating state, reducing the possibility of human operating errors, and improving the overall safety and reliability of the medical device.

[0045] Back to Figure 2 , other structures included in the movable mechanism 400 are described. Figure 2As shown, the movable mechanism 400 further includes a release handle 431, a second rotating shaft 432, and a connecting rod 433. The release handle 431 is operably disposed on the base 201 for controlling the first switch 411. The second rotating shaft 432 is disposed on the base 201. One end of the connecting rod 433 is connected to the second rotating shaft 432, and the other end is connected to the release handle 432. In addition, the connecting rod 433 is connected to the first switch 411 via a cable 434, one end of the cable 434 is connected to the connecting rod 433, and the other end is connected to the first switch 411.

[0046] The user operates (e.g., presses, pulls, etc.) the release handle 431 to activate the mechanical linkage system composed of the above-mentioned parts, thereby controlling the first switch 411. Specifically, when the release handle 431 is operated, the first switch 411 is pulled open through the connecting rod 433 and the cable 434 to become an open state. In this open state, the operating panel 200 can rotate freely. When the release handle 431 is released, the first switch 411 is restored to the locked state via the above-mentioned reset element 414, and the operating panel 200 remains in a fixed position. By adopting the above-mentioned control method, the operating convenience and safety of the medical device can be improved.

[0047] In some embodiments, a hollow frame structure 435 is provided on the base 201 at one side of the connecting rod 433 close to the release handle 431. The connecting rod 433 passes through the frame structure 435 and is connected to the second rotating shaft 432, and moves around the second rotating shaft 432 in a direction parallel to the base 201.

[0048] By providing the hollow frame structure 435, support and guidance are provided for the connecting rod 433 to prevent it from swinging up and down, thereby ensuring its stability during movement, so that the connecting rod 433 can smoothly and reliably transmit force and movement when operating the release handle 431.

[0049] In addition, in this embodiment, the frame structure 435 is set as a rectangular frame, but it is not limited thereto. As long as the above-mentioned effect can be achieved, it can be set to any possible shape. In addition, in this embodiment, the frame structure 435 is an independent component and is installed on the base by fasteners such as screws, but it can also be formed as a whole with the base. In addition, the frame structure 435 can be made of self-lubricating POM material, etc.

[0050] In some embodiments, a buffer is also provided on at least a portion of the inner wall of the frame structure 435 that contacts the connecting rod 433. In some embodiments, buffers can be provided at multiple locations on the inner wall as needed. The shape and size of the buffer can be designed according to the motion trajectory and force conditions of the connecting rod 433 to ensure the best buffering effect. In addition, the buffer can be made of a soft, highly elastic material (such as rubber, etc.), or a self-lubricating material, etc.

[0051] By providing a buffer, the impact and vibration generated by the connecting rod 433 during movement can be absorbed and dispersed, and the shaking and noise during the process can be reduced. In addition, the direct contact between the connecting rod 433 and the inner wall of the frame structure 435 can also be reduced, reducing wear and scratches.

[0052] In addition, similar to the above-mentioned reset element 414, a reset element may also be provided on the connecting rod 433. One end of the reset element is connected to the connecting rod 433, and the other end is connected to the base 201. Similarly, by providing the reset element at the connecting rod 433, an automatic reset function can also be achieved, thereby ensuring that the medical device remains stable in a non-operating state, reducing the possibility of human operating errors, and improving the overall safety and reliability of the medical device.

[0053] Figure 4 is a partial schematic diagram showing the base 201 involved in the first embodiment of the present utility model. Figure 2 The release handle 431 in FIG. Figure 4 As shown, the base 201 also has a grip portion 201a, and the release handle 431 is installed in the slit of the grip portion 201a. The release handle 431 includes a main body 431m and a protrusion 431p extending from the main body 431m, and the protrusion 431p is configured to isolate external foreign matter from entering the slit when the release handle 431 is in an operating state.

[0054] By providing the raised portion 431p in the release handle 431, when the release handle 431 is operated, not only can dust, liquid or other foreign matter be prevented from entering the slit, thus avoiding interference or damage to the operation of the release handle 431, but a safe and stable holding area can also be provided for the operator, effectively preventing finger pinching accidents when the release handle 432 is released, thereby helping to improve the overall safety of the medical device and user experience.

[0055] In addition, in some embodiments, in the grip portion 201a, a polymer film is provided on the inner surface opposite to the upper surface of the release handle 431 when the release handle 431 is in the operating state. The polymer film may be a polyester film or a PET film, such as Maylar. In addition, the polymer film may be fixed to an appropriate position on the inner surface of the grip portion 201a by bonding, snapping, or other methods. By providing a polymer film at an appropriate position on the grip portion 201a, the release handle 431 can be protected from wear due to friction during multiple operations, thereby maintaining a neat appearance and durability of the release handle.

[0056] Figure 5 1 is a cross-sectional view showing a medical device 1000 according to Embodiment 2 of the present invention. The medical device 1000 according to Embodiment 2 is substantially the same as Embodiment 1, and mainly includes a display 100, an operation panel 200, a column 300, a movable mechanism 400, a main unit 500, and casters 600. Figure 5 In the embodiment, only the parts other than the main body 500 and the caster 600 are shown. However, the difference between the embodiment 2 and the embodiment 1 is that the movable mechanism 400 includes a lifting part 420 disposed in the column 300 in addition to the rotating part 410 described in the embodiment 1. In the following, only the different points are described in detail, and the rest are not repeated.

[0057] like Figure 5 As shown, the lifting part 420 is provided with a second switch 421. When the second switch 421 is turned on, the operation panel is allowed to be operated to lift. Specifically, the lifting part 420 includes a gas spring 422 and a connecting rod 423. When the second switch 421 is turned on, the gas spring 422 can extend and push the connecting rod 423 to move, thereby driving the operation panel 200 to rise.

[0058] In the second embodiment, when the lifting part 420 is provided, the release handle 431 is configured to simultaneously control the first switch 411 of the rotating part 410 and the second switch 421 of the lifting part 420. Figure 2 As shown, the connecting rod 433 is connected to the first switch 411 through the cable 434 and is also connected to the lifting part 420 through another cable. Therefore, the first switch 411 and the second switch 421 can be turned on at the same time by operating the release handle 431, thereby controlling the rotation and lifting of the operation panel 200.

[0059] The medical device involved in the present invention has been described above, but the structures shown in the above exemplary embodiments are only examples of the present invention, and can be combined with other known technologies, or a part of the structure can be omitted or changed within the scope of the present invention.

[0060] Furthermore, the present invention can freely combine the various embodiments within the scope of the present invention, or modify any structural elements of the various embodiments, or omit any structural elements of the various embodiments.
