[0001] The invention relates to the technical field of operating tables, and in particular to a body position adjusting device for ultrasonic examination. Background Art

[0002] In the field of modern medicine, ultrasound examination is a very common and important diagnostic method. It uses the physical properties of ultrasound to obtain images of internal organs of the human body by transmitting and receiving ultrasound, thereby helping doctors diagnose diseases. Ultrasound examination has the advantages of being non-invasive, real-time, low-cost and easy to operate, so it has broad application prospects in clinical applications.

Traditional manual or electric adjustment devices may not meet the special needs of the elderly, causing discomfort to the elderly during the examination. The lack of protective devices on the edge of the bed board can easily cause the elderly to fall off the operating table when turning over, posing a safety hazard; if the electric adjustment device fails or the power goes out, it will cause a sudden fall during the assisted turning over, causing the elderly to be hit and frightened.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0030] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Embodiment 1 like Figure 1-8 As shown, a body position adjustment device for ultrasonic examination proposed by the present invention comprises a lifting mechanism 1, a frame 2, a bed 3, a turning mechanism 4 and a driving unit; The frame 2 is arranged on the lifting mechanism 1; the lifting mechanism 1 can drive the frame 2 to move and can adjust the height of the frame 2 and the bed body 3; the bed body 3 includes two side panels 302 with one side being slidably connected to the frame 2, and a bed board 301 with two ends being rotatably connected to the two side panels 302 respectively; the turning mechanism 4 is rotatably arranged on the frame 2 and slidably connected to the bed board 301; the driving unit includes a gear pump 5 arranged on the frame 2, a driving mechanism 6 arranged on the gear pump 5 for driving the turning mechanism 4 to rotate, a liquid supply mechanism 7 connected to the gear pump 5, and a protection unit 8 arranged on the liquid supply mechanism 7 and slidably connected to the gear pump 5.

[0031] The frame 2 is provided with a sliding groove 201; a sliding column 303 is provided on one side of the side plate 302 that is slidably connected to the frame 2; the sliding column 303 is slidably provided in the sliding groove 201; a plurality of supporting columns 202 that abut against the bed board 301 are provided on the frame 2. A backrest 304 is rotatably provided on the bed board 301; a telescopic cylinder 305 for driving the backrest 304 to flip is rotatably provided on the frame 2; the telescopic cylinder 305 drives the backrest 304 to flip, so that the backrest 304 can support the patient from the back and lift the patient up, so that the patient can sit up or lie half-lying, and the doctor can examine the patient conveniently; because the sliding column 303 slides in the sliding groove 201, the two side plates 302 can move relative to each other.

[0032] The flipping mechanism 4 includes a rotating rod 402 rotatably set on the frame 2, a plurality of V-shaped frames 401 that are all set on the rotating rod 402, a plurality of sliding rollers 403 that are rotatably set on both ends of the V-shaped frames 401, and two electromagnetic limit assemblies 404 that are both set on the frame 2 and clamped with the side plate 302.

[0033] In this embodiment, when it is necessary to assist the patient to tilt to one side, the side panel 302 on the side facing the side direction is locked by the electromagnetic limiting assembly 404, while the other side panel 302 is unlocked, and the sliding column 303 cooperates with the electromagnetic limiting assembly 404 to make the side panel 302 in a horizontal state, so that the patient can be supported when the patient turns over to prevent the patient from falling from the inclined bed board 301, and the driving unit drives the rotating rod 402 to rotate, and the rotating rod 402 drives the V-shaped frame 401 to rotate, so that the V-shaped frame 401 drives the sliding roller 403 to move, and the sliding roller 403 contacts the lower part of the bed board 301, and because the two sides of the bed board 301 are rotatably connected to the side panels 302, the side panels 302 facing the flipping direction are in a relatively fixed state. Therefore, the bed board 301 needs to rotate around the rotating connection with the side board 302, so as to drive the patient to assist in turning sideways, and the other side of the bed board 301 drives the other side board 302 to move, so that the side board 302 is in an inclined position, which can support the bed board 301 and prevent the bed board 301 from shaking; and the V-shaped frame 401 of the V-shaped structure can switch back and forth between the two directions, and can push the bed board 301 to turn over to either side, which can better cooperate with the medical staff's examination. Through various adjustment functions, the examination can be more thorough, and it has stronger pertinence for patients with difficulty in limb movement such as the elderly, and can assist medical staff in conducting detailed examinations during ultrasound examinations, and can be operated without the assistance of medical staff in turning over.

[0034] Compared with the operating bed or examination bed that tilts to one side in the prior art, since the side panels 302 can be supported at the sides, the patient can be prevented from sliding off the bed board 301. In normal use, the bed board 301 and the side panels 302 are both in a horizontal state, which is convenient for the patient to lie on. The armrests are relatively added to protect the patient. The flat bed board 301 and the side panels 302 will not affect the medical staff's inspection operations, and the inspection probe will not be blocked by the armrests, so that the inspection can be conveniently carried out.

[0035] Fixing the lifting mechanism 1, the electromagnetic limit assembly 404, the telescopic cylinder 305 and the controller of the driving mechanism 6 to the ultrasonic detector can make it more convenient for medical staff to operate. The lifting mechanism 1 can be controlled to move through the controller, and the electromagnetic limit assembly 404 and the driving mechanism 6 are linked, that is, when it is necessary to move in a certain direction, the electromagnetic limit assembly 404 in that direction pops out and gets stuck on the side plate 302 on that side, thereby achieving the purpose of flipping, and the electromagnetic limit assembly 404 on the other side is retracted, so that the side plate 302 on the other side can slide and work normally. The electromagnetic limit assembly 404 includes an electromagnetic driving mechanism and a limit latch. When limiting is required, the limit latch is pushed to move by the electromagnetic driving mechanism, so that the limit latch is inserted into the side plate 302 to fix the side plate 302.

[0036] Embodiment 2 like Figure 1-8 As shown, a body position adjustment device for ultrasonic inspection proposed by the present invention, compared with the first embodiment, the gear pump 5 in this embodiment includes a shell 501 arranged on the frame 2, two gears 502 that are rotatably arranged in the shell 501 and meshingly connected, two rotating shafts 503 that are arranged on the gears 502, and a friction disk 504 that is arranged on the upper rotating shaft 503 and connected to the protection unit 8.

[0037] The driving mechanism 6 includes a support frame 603 arranged on the shell 501, a driving motor 601 arranged on the support frame 603 and having an output end connected to the lower rotating shaft 503, and a belt transmission assembly 602 arranged on the upper rotating shaft 503 and connected to the rotating rod 402.

[0038] The liquid supply mechanism 7 includes a liquid storage tank 701 arranged on the shell 501, two liquid suction pipes 702 are arranged and are both arranged on the liquid storage tank 701, two flow pipes 703 are arranged and one end is arranged on the liquid suction pipe 702 and the other end is arranged on the shell 501, and a three-way 704 is arranged on the flow pipe 703 and connected with the protection unit 8; a one-way valve is arranged in the liquid suction pipe 702.

[0039] In this embodiment, the driving motor 601 drives the gear 502 to rotate through a support frame 603, and the gear 502 drives another gear 502 to rotate, thereby driving the upper rotating shaft 503 to rotate, and the rotating shaft 503 transmits power to the rotating rod 402 through the belt transmission assembly 602, so that the rotating rod 402 can rotate, push the bed board 301 to flip, and transmit power to the friction disk 504, so that the friction disk 504 can rotate synchronously; When the two gears 502 rotate, the liquid in the liquid storage tank 701 will be sucked out through the circulation pipe 703 and the suction pipe 702. The one-way valve in the suction pipe 702 allows the liquid in the liquid storage tank 701 to be sucked out, and cannot flow back into the liquid storage tank 701 through the suction pipe 702, so that the reflux part of the liquid can only flow through the protection unit 8, so that the protection unit 8 has complete liquid. When the speed becomes faster, the liquid will rush into the protection unit 8 quickly, increasing the pressure in the protection unit 8, so that the protection unit 8 clamps the friction plate 504, slowing down the speed of the friction plate 504, so that it can move smoothly at startup.

[0040] When an accident causes the drive motor 601 to fail, the bed board 301 can also be turned over at the moment of tipping over, and the liquid in the circulation pipe 703 will instantly rush into the protection unit 8, forcing the protection unit 8 to clamp the friction disk 504 and automatically brake. When the liquid in the friction component 801 gradually flows back to the tee 704 through the return pipe 804, the pressure is gradually reduced, so that the friction disk 504 can rotate, and then the liquid medium is pumped into the gear 502, so that the friction disk 504 can rotate smoothly, avoiding the bed board 301 from directly hitting the frame 2, and protecting the patient on the bed board 301. The deceleration by the liquid medium plus hydraulic friction can avoid the collision of rigid brakes, and the service life of the bed board 301 can be increased. It can also reduce the impact force on the patient and avoid scaring the patient.

[0041] Embodiment 3 like Figure 1-8 As shown, a body position adjustment device for ultrasonic inspection proposed by the present invention, compared with embodiment one or embodiment two, the protection unit 8 in this embodiment includes a friction component 801 arranged on the liquid storage tank 701 and slidably connected and abutting with the friction disk 504, a pushing component 802 arranged on the friction component 801 and abutting with the friction component 801, a connecting pipe 803 whose two ends are respectively connected to the pushing component 802 and the tee 704, and a reflux pipe 804 arranged on the pushing component 802.

[0042] The friction assembly 801 includes a clamping frame 8011 arranged on the liquid storage tank 701, a friction plate 8012 slidably arranged on the clamping frame 8011, and a connecting handle 8013 arranged on the friction plate 8012; the friction plate 504 is embedded in the clamping frame 8011, and the friction plate 8012 is slidably connected and abutted with the friction plate 504.

[0043] Among them, the cross-section of the connecting handle 8013 is a T-shaped structure, and the connecting handle 8013 is provided with an elastic member 8014 at both ends respectively connected to the connecting handle 8013 and the clamping frame 8011; the elastic member 8014 pushes the connecting handle 8013 to move toward the principle friction plate 8012, so that the friction plate 8012 can be separated from the friction disk 504 under normal operation, which can reduce friction.

[0044] One side of the friction disc 504 is embedded in the friction assembly 801. When the pushing assembly 802 pushes the connecting handle 8013 to move, the friction plate 8012 is pushed to move, so that the friction plate 8012 is against the friction disc 504, and cooperates with the clamping frame 8011 to increase the friction force with the friction disc 504, thereby slowing down the friction disc 504 and making the friction disc 504 move more smoothly.

[0045] Furthermore, the pushing assembly 802 includes a liquid cylinder 8021 arranged on the clamping frame 8011, a blocking sleeve 8022 arranged in the liquid cylinder 8021, a piston 8023 slidably arranged in the liquid cylinder 8021 and abutting against the blocking sleeve 8022, a support sleeve 8025 threadedly connected to the liquid cylinder 8021, an elastic member 8024 arranged in the liquid cylinder 8021 and abutting against the piston 8023 and the support sleeve 8025 at both ends, and a push rod 80231 arranged on the piston 8023 and abutting against the connecting handle 8013.

[0046] In this embodiment, when the flow rate increases, the pressure of the liquid entering the liquid cylinder 8021 increases, and when the reflux pipe 804 cannot discharge the liquid in time, the pressure in the liquid cylinder 8021 will continue to increase, thereby pushing the piston 8023 to move. The elastic member 8024 provides a supporting force for the piston 8023, which can ensure that the piston 8023 does not move under a relatively small pressure, and the blocking sleeve 8022 can limit the position of the piston 8023. By rotating the supporting sleeve 8025, the depth to which the supporting sleeve 8025 is screwed into the liquid cylinder 8021 can be adjusted, thereby adjusting the supporting force of the elastic member 8024 given to the piston 8023. When the thrust given to the piston 8023 by the liquid cylinder 8021 is greater than the thrust given to the piston 8023 by the elastic member 8024, the piston 80 When the supporting force of 23 is applied, the piston 8023 will drive the push rod 80231 to move, so that the push rod 80231 contacts the connecting handle 8013, pushes the connecting handle 8013 to move, and the connecting handle 8013 pushes the friction plate 8012 to move, so that the friction plate 8012 clamps the friction disk 504, increases the friction force, and thus can slow down the rotation speed of the friction disk 504. When the rotation speed decreases, the flow rate entering the liquid cylinder 8021 decreases, thereby reducing the pressure in the liquid cylinder 8021, and the elastic member 8024 pushes the piston 8023 to move, while the elastic member 1 8014 pushes the connecting handle 8013 to move, so that the friction plate 8012 reduces the pressure on the friction disk 504, thereby enabling the rotation speed of the friction disk 504 to be in a stable state.

[0047] The present invention can work directly at the moment when the driving motor 601 is started, and the resistance generated by the liquid medium can enable the driving motor 601 to start smoothly, preventing the torque and speed from being too large due to sudden starting, causing large impact and fluctuation, so that the starting of the driving motor 601 is more stable; When the driving motor 601 fails in the middle of operation, the downward pressure of the bed plate 301 can be converted into the rotation of the friction plate 504. When the rotation speed is fast, the friction plate 504 can be clamped by the protection unit 8, so that the friction plate 504 is decelerated and finally falls smoothly. When the pressure is lost or the speed is reduced, the protection unit 8 automatically separates from the friction plate 504, so that the friction plate 504 can move normally. By pumping liquid medium into the gear pump 5, the gear pump 5 can be lubricated to prevent dry meshing between the gears 502, which can increase the service life of the gears 502. When the gears 502 rotate, they are affected by the resistance of the medium, which will make the movement of the driving motor 601 more stable, so that they have a complementary effect.

[0048] This embodiment has the following beneficial effects: 1. Enhanced starting stability: Through the resistance generated by the liquid medium, the present invention can achieve smooth operation at the moment of starting the drive motor 601, effectively preventing excessive torque and speed caused by sudden starting, thereby reducing the impact and discomfort to the patient.

[0049] 2. Safety failure protection: In the event of failure of the drive motor 601, the present invention can convert the descending pressure of the bed board 301 into the rotation of the friction plate 504, and through the automatic braking function of the protection unit 8, ensure that the bed board 301 descends smoothly to protect the safety of the patient.

[0050] 3. Automatic adjustment and recovery: The protection unit 8 can automatically clamp the friction disc 504 to slow down when the speed is too fast, and automatically separate from the friction disc 504 after the pressure is reduced or the speed is reduced, so that the friction disc 504 can resume normal movement, thereby improving the intelligence and reliability of the device.

[0051] 4. Prolong service life: By pumping the liquid medium into the gear pump 5, not only the gear 502 is lubricated to prevent dry meshing, but also the service life of the gear 502 is prolonged and the maintenance cost is reduced.

[0052] 5. Improve the stability of movement: When the gear 502 rotates, it is affected by the medium resistance, which makes the movement of the drive motor 601 more stable, and realizes the complementary effect between the drive motor 601 and the gear pump 5.

[0053] 6. Optimizing the utilization of liquid medium: The design of the liquid supply mechanism 7 and the protection unit 8 in the present invention ensures the effective utilization of the liquid medium. At the same time, through the cooperation of the reflux pipe 804 and the tee 704, the recycling of the liquid medium is realized, thereby improving the efficiency of the system.

[0054] 7. Reduce startup shock: The protection unit 8 is designed to work directly when the drive motor 601 is started, reducing the startup shock and providing a more comfortable and safe examination environment for the patient.

[0055] 8. Strong adaptability: The design of the present invention takes into account a variety of possible working conditions and failure modes, has strong environmental adaptability and operational flexibility, and is suitable for different types of ultrasonic inspection needs.

[0056] 9. Mechanical structure: The present invention adopts a mechanical structure for braking, which can ensure its stability in operation and has a low failure rate.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
