Detailed Implementation

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0037] refer to Figures 1 to 4 This application provides a transport device 100. The transport device 100 includes a base 1, a turntable 2, and a speed control assembly 3. The base 1 includes an upper surface 11. The turntable 2 is disposed on the upper surface 11 and rotatably connected to the base 1. The turntable 2 includes a bearing surface 21 disposed away from the upper surface 11. The bearing surface 21 is used to bear the patient to be transported. The turntable 2 also includes a flange 22. The flange 22 is disposed on the side of the turntable 2 near the upper surface 11. The speed control assembly 3 includes a fixed seat 31 and a pedal 32. The fixed seat 31 is connected to the upper surface 11. One end of the pedal 32 is pivotally connected to the fixed seat 31, and the other end abuts against the side of the flange 22 away from the upper surface 11.

[0038] Medical staff can control the tightness of the contact between pedal 32 and flange 22 by stepping on pedal 32, thereby controlling the rotation speed of turntable 2. For example, when medical staff do not step on pedal 32 at all, turntable 2 cannot rotate, and medical staff can move the patient to be transferred to the carrying surface 21. When medical staff step on pedal 32, the end of pedal 32 away from the fixed seat 31 separates from flange 22, and the speed control component 3 releases the restriction on turntable 2, so medical staff can transfer the patient by rotating the patient. Medical staff can control the engagement between pedal 32 and flange 22 by controlling the force applied to pedal 32, thereby controlling the rotation speed of turntable 2.

[0039] As can be seen, the transfer device 100 of this application allows a medical staff member to lock the turntable 2 and control its speed, thereby facilitating the transfer of patients who have difficulty walking independently. Simultaneously, the transfer device 100 controls its rotation speed by stepping on the pedal 32, making operation simple and ensuring high safety performance by keeping the speed control component 3 away from the load-bearing surface 21, thus preventing injury to the patient.

[0040] In an optional embodiment, the diameter D2 of the turntable 2 is larger than the diameter D1 of the base 1. Increasing the diameter D2 of the turntable 2 increases the area of ​​the bearing surface 21, enabling the transport device 100 to transport patients of different body sizes. Decreasing the diameter D1 of the base 1 relative to the diameter D2 of the turntable 2 optimizes the size of the transport device 100, avoiding the need for an excessively large footprint for operation.

[0041] In an optional embodiment, the diameter D1 of the base 1 is greater than or equal to 340 mm and less than or equal to 400 mm. For example, the diameter D1 can be any value between 340 mm, 345 mm, 350 mm, 355 mm, 360 mm, 365 mm, 370 mm, 375 mm, 380 mm, 385 mm, 390 mm, 395 mm, 400 mm, or any value between these values. If the diameter D1 of the base 1 is reduced, the contact area between the transfer device 100 and the ground decreases, which may cause the patient's center of gravity to deviate from the rotation axis A when the transfer device 100 is bearing the patient's weight, resulting in the transfer device 100 tipping over. If the diameter D1 of the base 1 is too large, the footprint of the transfer device 100 increases, and the distance between the medical staff and the rotation axis A increases, which may make it difficult for the medical staff to stably hold the patient on the turntable 2. A diameter D1 within this range can optimize the chassis size while ensuring safety during use.

[0042] In an optional embodiment, the diameter D2 of the turntable 2 is greater than or equal to 350 mm and less than or equal to 450 mm. For example, the diameter D2 can be any value between 350 mm, 355 mm, 360 mm, 365 mm, 370 mm, 375 mm, 380 mm, 385 mm, 390 mm, 395 mm, 400 mm, 405 mm, 410 mm, 415 mm, 420 mm, 425 mm, 430 mm, 435 mm, 440 mm, 445 mm, and 450 mm. Increasing the diameter D2 of the turntable 2 increases the area of ​​the supporting surface 21, thus increasing the contact area between the patient and the supporting surface 21. However, this also increases the distance between the medical staff and the rotation axis A of the turntable 2, making it difficult to keep the patient as close to the rotation axis A as possible, potentially causing the patient and the transport device 100 to tip over. A smaller diameter D2 on the turntable 2 allows the patient to be kept as close as possible to the axis of rotation A, but this increases the difficulty for medical staff to keep the patient on the support surface 21. Therefore, a diameter D2 within this range can balance the stability of the patient on the support surface 21 with the safety and convenience of medical staff operation.

[0043] It should be understood that in embodiments where the diameter D2 of the turntable 2 is greater than the diameter D1 of the base 1, those skilled in the art can still select values ​​within the aforementioned range, but should ensure that the diameter D2 of the turntable 2 is still greater than the diameter D1 of the base 1. For example, if the diameter D2 of the turntable 2 is taken as the minimum value of 350mm within the aforementioned range, then the diameter D1 of the base 1, in order to satisfy the numerical relationship with the diameter D2 of the turntable 2, can be greater than or equal to 340mm and less than 350mm.

[0044] In some optional embodiments, the speed control assembly 3 further includes a torsion spring 34 and a pin 35. The pin 35 connects the mounting base 31 and the pedal 32, allowing the pedal 32 to pivot relative to the mounting base 31 about the pin 35. The torsion spring 34 is fitted onto the pin 35 and always applies a force away from the upper surface 11 to the end of the pedal 32 away from the flange 22. In other words, the torsion spring 34 causes the pedal 32 to tend to always be in contact with the flange 22. Thus, when the medical staff releases the pedal 32, the pedal 32 can actively return to engagement with the flange 22. Therefore, the medical staff can control the rotation speed of the turntable 2 by controlling the force applied to the pedal 32 without having to press the pedal 32 towards the flange 22 with their foot. This arrangement further simplifies the operation of the speed control assembly 3, thereby reducing the difficulty of operation and improving the safety of single-person operation.

[0045] Optionally, the speed control assembly 3 also includes a damping pad 33. The damping pad 33 is connected to the side of the pedal 32 away from the fixed end and abuts against the flange 22. The damping pad 33 can be supported by any soft material such as rubber. By setting the damping pad 33, the damping between the speed control assembly 3 and the turntable 2 is improved, thus enabling more precise speed control of the turntable 2. Furthermore, the contact between the damping pad 33 and the flange 22 is a soft medium and a hard medium. When the flange 22 and the damping pad 33 move relative to each other, the flexibility of the damping pad 33 can avoid the noise of friction between rigid materials and prevent frictional damage to the flange 22. It can be seen that the damping pad 33 can prevent the noise generated by friction from causing discomfort to medical staff and patients, and improve the service life of the transport device 100.

[0046] Damping pad 33 can be as follows Figure 4 As shown, the damping pad 33 is connected to the pedal 32 by bolts, thereby improving the ease of replacement. Furthermore, the bolted connection between the bolt and the pedal 32 prevents the damping pad 33 from separating from the pedal 32 when the flange 22 and the damping pad 33 move relative to each other. Alternatively, the damping pad 33 can also be connected to the pedal 32 by adhesive, snap-fit, or other methods. This application does not limit this.

[0047] The turntable 2 can rotate freely around the axis of rotation A, allowing medical personnel to rotate patients on the support surface 21 to different positions as needed. However, to improve the safety of the transfer device 100, in some embodiments, the turntable 2 includes a notch 29 on the flange 22. The notch 29 extends around the axis of rotation A of the turntable 2. The base 1 includes a limiting pin 14 on the upper surface 11. The limiting pin 14 is located in the notch 29. When the turntable 2 rotates to its limit position, the limiting pin 14 abuts against the flange 22. By providing the notch 29, the limit positions of the turntable 2 in the counterclockwise and clockwise rotation directions can be limited. This arrangement prevents the patient from rotating and falling off the turntable 2 and causing injury when the patient is on the support surface 21 and the medical personnel lose control of the patient's body. Therefore, this arrangement improves the transfer safety of the transfer device 100.

[0048] The limiting pin 14 may be fitted with a rubber sleeve to prevent hard collision between the limiting pin 14 and the flange 22. Alternatively, the limiting pin 14 may be integrally formed with the base 1 and protrude from the upper surface 11. Or, the base 1 may include a mating hole 15 on the upper surface 11, and the limiting pin 14 is connected to the mating hole 15 by means of threads, interference fit, or other methods. This arrangement allows for the replacement of the limiting pin 14 in the transfer device 100, thereby enabling maintenance of the limiting pin 14 and ensuring its limiting effect.

[0049] The pivotal connection between the base 1 and the turntable 2 can be achieved by inserting the turntable 2 into the base 1 for pivoting. Alternatively, as shown in the embodiment in the attached figure, the base 1 includes a rotating shaft 12 disposed on the upper surface 11. The turntable 2 includes a rotating hole 23. The rotating hole 23 is fitted onto the rotating shaft 12. This embodiment can minimize the height between the upper surface 11 and the ground while ensuring the mating area between the turntable 2 and the base 1. That is, when the turntable 2 is subjected to force and flips, the protruding rotating shaft 12 can prevent the turntable 2 from disintegrating from the base 1, ensuring the limiting position of the turntable 2 and the base 1. In addition, the height distance control between the upper surface 11 and the ground can ensure the convenience and limb stability of medical personnel when operating the speed control component 3 without having to lift their legs. This arrangement can ensure the stability of the medical personnel themselves, thereby ensuring the stability of the patient when the medical personnel are transporting the patient.

[0050] Furthermore, the base 1 includes a boss 13 disposed between the upper surface 11 and the rotating shaft 12. The diameter of the boss 13 is larger than the diameter of the rotating shaft 12. The transfer device 100 includes a needle roller bearing 4. The needle roller bearing 4 is sleeved on the boss 13, and one side abuts against the upper surface 11 along its axial direction, while the other side abuts against the end face of the turntable 2. The boss 13 is disposed between the upper surface 11 and the rotating shaft 12, thus creating a gap between the upper surface 11 and the turntable 2, preventing direct contact between the turntable 2 and the upper surface 11. At the same time, the placement of the needle roller bearing 4 can reduce friction between the turntable 2 and the upper surface 11 when the turntable 2 rotates relative to the base 1 around the rotation axis A. When the turntable 2 carries the weight of a patient, the needle roller bearing 4 can ensure the smoothness of the rotation of the turntable 2, thereby ensuring the safety of medical personnel transporting patients alone.

[0051] Similarly, the turntable 2 includes an abutment portion 24 disposed inside the rotating hole 23. The transfer device 100 may also include a ball bearing 5. The inner ring of the ball bearing 5 is fitted onto the rotating shaft 12. The outer ring of the ball bearing 5 mates with the wall surface of the rotating hole 23. The ball bearing 5 abuts against the abutment portion 24. The ball bearing 5 ensures a tight fit between the rotating shaft 12 and the turntable 2, preventing the turntable 2 from wobbling in its radial direction during rotation, and also improving the smoothness of rotation between the turntable 2 and the rotating shaft 12.

[0052] The rotating hole 23 can be configured as a blind hole, meaning that the rotating hole 23 is not connected to the outside world on one side of the bearing surface 21. This configuration improves the flatness of the bearing surface 21, preventing unevenness that could cause patients to trip. In some optional embodiments, the rotating hole 23 penetrates the turntable 2. The rotating hole 23 penetrating the turntable 2 facilitates the assembly of internal structures such as the ball bearing 5. To improve the flatness of the turntable 2 on one side of the bearing surface 21 in this embodiment, the turntable 2 also includes a cover 25. The cover 25 closes the end of the rotating hole 23 away from the base 1. The surface of the cover 25 away from the base 1 is flat. The cover 25 prevents external impurities from entering the interior of the rotating hole 23 through the bearing surface 21, which could cause uneven rotation of the turntable 2 and the base 1 later. Simultaneously, the surface of the cover 25 is flat. This configuration minimizes the presence of the cover 25 on the bearing surface 21, thereby reducing the likelihood of patients tripping over it.

[0053] In an optional embodiment, a washer 6 and a nut 7 are provided between the cover 25 and the ball bearing 5. The washer 6 is disposed between the nut 7 and the ball bearing 5, and the cover 25 is disposed on the side of the nut 7 away from the washer 6. The nut 7 cooperates with the rotating shaft 12, so that the washer 6 can be kept pressed tightly against the ball bearing 5, thereby ensuring the cooperation between the ball bearing 5, the rotating shaft 12, and the turntable 2.

[0054] To prevent patients from slipping and falling on the support surface 21, the turntable 2 includes a recess 26 and an anti-slip pad 27. The recess 26 is recessed from the support surface 21. The anti-slip pad 27 is disposed in the recess 26. The anti-slip pad 27 increases the friction at the support surface 21, thereby reducing the possibility of slipping. In addition, the recess 26 prevents the anti-slip pad 27 from protruding excessively from the support surface 21, which would reduce the flatness of the support surface 21 and cause patients to trip. Optionally, the recess depth of the recess 26 and the thickness of the anti-slip pad 27 are set to be the same, that is, the anti-slip pad 27 is flush with the support surface 21, so that the support surface 21 remains a flat surface after the anti-slip pad 27 is inserted into the recess 26, thereby reducing the possibility of patients tripping over the protruding anti-slip pad 27 or the protruding wall of the recess 26.

[0055] Optionally, the number of recesses 26 may be multiple. The multiple recesses 26 are distributed around the rotation axis A of the turntable 2. The number of anti-slip pads 27 corresponds one-to-one with the number of recesses 26. In this embodiment, the recesses 26 are discretely distributed around the rotation axis A on the bearing surface 21. Therefore, the anti-slip pads 27 disposed inside the recesses 26 can prevent relative rotation between the anti-slip pads 27 and the recesses 26 around the rotation axis A when subjected to tangential force. This arrangement improves the fixing force of the anti-slip pads 27, further enhancing the safety of the transport device 100 in transporting patients.

[0056] The anti-slip mat 27 can be connected to the recess 26 by adhesive or snap-fit. This method allows the surface of the recess 26 away from the bearing surface 21 to be flat, thereby improving the smoothness of the patient's foot when stepping on the bearing surface 21. Of course, the anti-slip mat 27 can also be connected to the recess 26 by screwing, thereby improving the stability of the connection between the anti-slip mat 27 and the recess 26.

[0057] Optionally, the turntable 2 also includes a baffle 28. The baffle 28 is disposed on the support surface 21. The baffle 28 is disposed around the outer periphery of the turntable 2 and protrudes toward the side away from the base 1. The baffle 28 can further restrict the range of motion of the patient's body, preventing the patient's legs from leaving the support surface 21 due to lack of support.

[0058] Furthermore, the angle α extending the baffle 28 around the turntable 2 is greater than or equal to 180° and less than or equal to 270°. For example, the angle α can be any value between 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, and 270°. Compared to the embodiment where the baffle 28 extends 360° around the turntable 2, this embodiment has a notch formed in the baffle 28, allowing medical personnel to move the patient onto the support surface 21 through the notch, after which the patient's movement is somewhat restricted by the baffle 28. This arrangement avoids the need for medical personnel to raise the patient to a higher height to place them on the support surface 21. Therefore, this arrangement improves convenience while ensuring the safety of the transfer device 100.

[0059] In an optional embodiment, the protrusion height H of the baffle 28 is greater than or equal to 10 mm and less than or equal to 30 mm. For example, the height H can be any value between 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, and 30 mm. If the protrusion height H of the baffle 28 is too small, the restraining effect of the baffle 28 on the patient's body will be reduced. If the protrusion height H of the baffle 28 is too large, it may cause the patient to trip and make it inconvenient for medical staff to operate. The protrusion height H within this range can better ensure the restraining effect on the patient while ensuring ease of use.

[0060] The baffle 28 can be detachably connected to the turntable 2 via bolts, screws, or other parts, as shown in the attached figure. Alternatively, the baffle 28 can also be connected to the turntable 2 by welding, bonding, snap-fitting, or other methods.

[0061] In various embodiments, both the upper surface 11 and the supporting surface 21 can be provided with arrow markings to indicate the rotatable direction of the turntable 2 to medical staff, thereby avoiding the need for medical staff to try rotating the turntable 2 in multiple directions. This arrangement can further improve the ease of operation of the transfer device 100 by medical staff, thereby improving the safety of patient transfer.

[0062] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
