The upper end of the leg 20 is connected to the bracket 10, and the roller 30 is arranged at the lower end of the leg 20 and can rotate around its own axis direction.

[0049] In other words, the medical transport bed 100 according to the embodiment of the present invention is mainly composed of a support 10, a slide rail assembly 40, a bed plate assembly 50, a leg 20 and a roller 30. The slide rail assembly 40 is mainly composed of a first slide rail 41, a second slide rail 42, a third slide rail 43 and a fourth slide rail 44. The support 10 can play a supporting role, and the leg 20 can play a supporting role for the support 10. Under the condition that the support 10 extends in the horizontal direction, the leg 20 can extend in the up and down direction to space the support 1020 from the ground. The roller 30 can be arranged at the lower end of the leg 20, and the roller 30 can rotate. By arranging the roller 30, the leg 20 and the support 10 can be moved on the ground.

[0050] The bracket 10 is provided with a slide rail assembly 40, and a bed board assembly 50 is provided above the slide rail assembly 40. The movement of the bed board assembly 50 can be achieved by providing the slide rail assembly 40. For ease of description, the slide rail assembly 40 is provided in the front-to-back direction. The first slide rail 41 and the second slide rail 42 are spaced apart and distributed in the left-right direction. Figure 2 As shown, the third slide rail 43 and the fourth slide rail 44 are respectively located in front of the first slide rail 41 and the second slide rail 42. The front end of the first slide rail 41 is connected to the rear end of the third slide rail 43, and the front end of the second slide rail 42 is connected to the rear end of the fourth slide rail 44. And the first slide rail 41 and the second slide rail 42 are linear slide rails arranged in parallel. The third slide rail 43 and the fourth slide rail 44 are arc-shaped slide rails, respectively, the third slide rail 43 is bent toward the direction of the second slide rail 42, and the fourth slide rail 44 is bent toward the direction of the first slide rail 41. In other words, the openings of the third slide rail 43 and the fourth slide rail 44 are arranged opposite to each other, the first end and the second end of the third slide rail 43 extend toward the position of the fourth slide rail 44, respectively, and the first end and the second end of the fourth slide rail 44 extend toward the position of the third slide rail 43, respectively.

[0051] The bed board assembly 50 includes a bed board, which is disposed on the first slider 45 and the second slider 46 and moves synchronously therewith. Figures 4 to 6 As shown, the left part of the bed board is connected to the first slide rail 41 or the third slide rail 43 through the first slider 45, and the right part of the bed board is connected to the second slide rail 42 or the fourth slide rail 44 through the second slider 46. The bed board is movable between the first state 51, the second state 52 and the third state 53 to adjust the position of the bed board and the bracket 10. When the bed board is in the first state 51, the left part of the bed board is slidably connected to the first slide rail 41 through the first slider 45, and the right part of the bed board is slidably connected to the second slide rail 42 through the second slider 46. The bed board can slide along the first slide rail 41 and the second slide rail 42 at the same time.

[0052] When the bed board is in the second state 52, the bed board is located above the second slide rail 42 and the third slide rail 43, respectively, the first slider 45 is located on the third slide rail 43, and the second slider 46 is located on the second slide rail 42. That is, the bed board rotates around the axis A at the left end of the bed board with the position where the right end of the bed board is connected to the second slide rail 42 as the axis (such as Figure 5 As shown), the left end of the bed board slides along the third slide rail 43.

[0053] When the bed board is in the third state 53, the first slider 45 is located on the third slide rail 43, the second slider 46 is located on the fourth slide rail 44, and the bed board rotates around the axis B at the right end of the bed board with the position where the left end of the bed board is connected to the third slide rail 43 as the axis (such as Figure 6 As shown in FIG. 1 , the right end of the bed plate slides along the fourth slide rail 44. Compared with the prior art, the transfer bed of the prior art can usually only translate the patient's head and feet synchronously, and cannot adjust the relative position and relative angle of the patient. The medical transfer bed 100 of the embodiment of the present invention can improve the convenience of movement for the patient and expand the range of movement.

[0054] Therefore, the medical transfer bed 100 according to the embodiment of the present invention can not only realize the transfer of patients, but also realize the micro-movement and angle adjustment of patients through the slide rail assembly 40, thereby improving the convenience of transfer.

[0055] In some specific embodiments of the present invention, the bracket 10 is provided with a bearing surface, the first slide rail 41 and the second slide rail 42 are located on the first plane, the third slide rail 43 and the fourth slide rail 44 are located on the second plane, the first plane is located above the bearing surface, and the second plane is located above or below the bearing surface. When the second plane is located above the bearing surface, the second plane is located above or below the first plane; the slide rail assembly 40 also includes: a first transition slide rail 47, a second transition slide rail 48, the first slider 45 and / or the second slider 46 includes: a lower slider 451, an elastic member 452 and an upper slider 453.

[0056] Specifically, the first end of the first transition slide rail 47 is connected to the first end of the first slide rail 41, the second end of the first transition slide rail 47 is connected to the first end of the third slide rail 43, the first transition slide rail 47 is an arcuate slide rail extending from the first end of the first slide rail 41 to the direction of the first end of the third slide rail 43, the first end of the second transition slide rail 48 is connected to the first end of the second slide rail 42, the second end of the second transition slide rail 48 is connected to the first end of the fourth slide rail 44, the second transition slide rail 48 is an arcuate slide rail extending from the first end of the second slide rail 42 to the direction of the first end of the fourth slide rail 44, the lower end of the lower slider 451 is connected to the slide rail assembly 40, the lower end of the elastic member 452 is connected to the upper end of the lower slider 451, the elastic member 452 is retractable along its own axial direction, the lower end of the upper slider 453 is connected to the upper end of the elastic member 452, and the upper end of the upper slider 453 is connected to the bed board.

[0057] In other words, the first slide rail 41 and the second slide rail 42 are respectively located on the first plane, and the first plane is located above the bearing surface. The third slide rail 43 and the fourth slide rail 44 are respectively located on the second plane. The first plane and the second plane can be staggered in the vertical direction. The relative position relationship between the first plane and the second plane may include the following: (1) the second plane is located below the bearing surface, and the first plane is located above the bearing surface and above the second plane; (2) the second plane is located above the bearing surface, and the first plane is located above the second plane; (3) the second plane is located above the bearing surface, and the first plane is located below the second plane. Through the above-mentioned settings, it is convenient to set the first plane and the second plane at different heights, which is convenient for the bed board to move at different heights.

[0058] In addition, if Figure 7 As shown, a first transition rail 47 is also provided between the first rail 41 and the third rail 43, and the transition connection between the first rail 41 and the third rail 43 can be achieved through the first transition rail 47. A second transition rail 48 is also provided between the second rail 42 and the fourth rail 44, and the transition connection between the second rail 42 and the fourth rail 44 can be achieved through the second transition rail 48. The first transition rail 47 and the second transition rail 48 are arc-shaped rails, which are conducive to smooth transition. It should be noted that the first slider 45 can also cooperate with the first transition rail 47 and slide along the axial direction of the first transition rail 47. When the first slider 45 slides along the first transition rail 47, it can cooperate with the limiting part to achieve the first slider 45 hovering on the first transition rail 47. Similarly, the second slider 46 can also cooperate with the second transition rail 48, which will not be described in detail here.

[0059] It should be noted that, by providing the first transition rail 47 and the second transition rail 48, it is possible to facilitate the first plane and the second plane to be staggered in the vertical direction, so that the bed board can be moved between different heights in the vertical direction.

[0060] In addition, the first slider 45 and / or the second slider 46 include a lower slider 451, an elastic member 452 and an upper slider 453, that is, the first slider 45 may include the lower slider 451, the elastic member 452 and the upper slider 453, the second slider 46 may include the lower slider 451, the elastic member 452 and the upper slider 453, or the first slider 45 and the second slider 46 may include the lower slider 451, the elastic member 452 and the upper slider 453 at the same time. Among them, the lower slider 451 is located above the upper slider 453, and the lower slider 451 is connected to the slide rail assembly 40, for example, connected to one of the first slide rail 41, the second slide rail 42, the third slide rail 43 and the fourth slide rail 44. The upper slider 453 is connected to the bed board. By providing the elastic member 452 between the upper slider 453 and the lower slider 451, the elastic property of the elastic member 452 can be used to realize the switching of the bed board between the first state 51, the second state 52 and the third state 53. For example, when the bed board is in the second state 52, the lower slider 451 of the first slider 45 is located on the third slide rail 43, and the second slider 46 is located on the second slide rail 42. At this time, the elastic member 452 of the first slider 45 can be in a stretched state. Then, the bed board switches from the second state 52 to the third state 53, and the second slider 46 slides to the fourth slide rail 44 via the second transition slide rail 48. During the sliding process, the elastic member 452 of the second slider 46 can be in a stretched state, and the expansion and contraction amount of the elastic member 452 can change in real time.

[0061] The bed board can also move in the fourth state and the fifth state. Specifically, when the bed board is in the fourth state, the bed board is in a state between the first state 51 and the second state 52. At this time, the first slider 45 is located on the first transition rail 47, and the second slider 46 is located on the second rail 42. When the bed board is in the fifth state, the bed board is in a state between the second state 52 and the third state 53. At this time, the first slider 45 is located on the third rail 43, and the second slider 46 is located on the second transition rail 48. By limiting that the bed board can also be in the fourth state or the fifth state, the range of the position and angle of the bed board can be further expanded, and the transportation flexibility can be further improved.

[0062] The bracket 10 is provided with a bearing surface, and the first plane can be arranged above the bearing surface, and the second plane can be arranged below the bearing surface, so that the bed board can be moved and transferred in the up and down directions.

[0063] In some specific embodiments of the present invention, Figure 8As shown, the upper end of the lower slider 451 and / or the lower end of the upper slider 453 are provided with a groove 454, and the end of the elastic member 452 is arranged in the groove 454; the first slider 45 and / or the second slider 46 also include: a limiter 455, which is arranged on the lower slider 451 and / or the upper slider 453, and the limiter 455 can be switched between an open state and a closed state. When the limiter 455 is in the open state, the limiter 455 is connected to one of the lower slider 451 and the upper slider 453, and a part of the elastic member 452 extends out of the groove 454; when the limiter 455 is in the closed state, the limiter 455 is connected to the lower slider 451 and the upper slider 453 at the same time, and the entire elastic member 452 is located in the groove 454. The limiter 455 can realize the locking and unlocking between the lower slider 451 and the upper slider 453. When the lower slider 451 and the upper slider 453 are locked, the elastic member 452 can be completely located in the groove 454 and will not expand or contract according to the state of the bed board. When the lower slider 451 and the upper slider 453 are unlocked, a part of the elastic member 452 can be located outside the groove 454 and can expand or contract freely, which is conducive to the switching of the bed board between different states. The limiter 455 can be a magnetic member or a mechanical structure, which is not limited here.

[0064] According to one embodiment of the present invention, the first slide rail 41 , the second slide rail 42 , the third slide rail 43 and the fourth slide rail 44 are respectively located on the same plane, so as to facilitate the bed board to switch between the first state 51 , the second state 52 and the third state 53 .

[0065] According to an embodiment of the present invention, the first slide rail 41, the second slide rail 42, the third slide rail 43 and the fourth slide rail 44 are respectively retractable along their own axial direction. By adopting a retractable structure, it is possible to avoid the first slide rail 41 and the second slide rail 42 being exposed to the outside world when the bed board moves from the first state 51 to the second state 52 or the third state 53, thereby affecting the appearance and safety. It is also possible to avoid the third slide rail 43 and the fourth slide rail 44 being exposed to the outside world when the bed board moves from the second state 52 or the third state 53 to the first state 51, thereby affecting the appearance and safety.

[0066] According to one embodiment of the present invention, the first slide rail 41, the second slide rail 42, the third slide rail 43 and the fourth slide rail 44 are respectively movably connected to the bracket 10. The positions of the first slide rail 41, the second slide rail 42, the third slide rail 43 and the fourth slide rail 44 can be moved, for example, the spacing between the first slide rail 41 and the second slide rail 42, the spacing between the third slide rail 43 and the fourth slide rail 44, and the position of the slide rail assembly 40 on the bracket 10 can be controlled, which can improve flexibility and applicability and can be applicable to bed boards of various sizes. In addition, the slide rail assembly 40 can be limited to move forward or backward relative to the bracket 10, further improving the range of the movable position of the bed board.

[0067] In some specific embodiments of the present invention, the roller 30 is a universal wheel to facilitate the sliding and reversing of the medical transport bed 100.

[0068] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, the medical transport bed 100 further includes: a piezoelectric strip 60 and a battery 70. The piezoelectric strip 60 is disposed on a portion of the outer circumference of the roller 30. The battery 70 is electrically connected to the piezoelectric strip 60. The piezoelectric strip 60 may be a piezoelectric ceramic or some material having a piezoelectric effect, which is not limited here. When the roller 30 rolls, the piezoelectric strip 60 can generate electricity according to the piezoelectric effect. By using the piezoelectric strip 60 and the battery 70 in combination, electrical energy storage can be achieved.

[0069] Alternatively, if Figure 3 As shown, the medical transport bed 100 further includes: a restraint belt 80, a fixing assembly 90 and a first controller. The first end of the restraint belt 80 is connected to the first side of the bed board. The second end of the restraint belt 80 is a magnetic member, which is detachably connected to the second side of the bed board. The restraint belt 80 and the bed board can cooperate to define a receiving channel. When in use, the patient can be located in the receiving channel, and the patient can be restrained by adjusting the size of the receiving channel to prevent the patient from being separated from the bed board, causing the patient to suffer secondary injury. The fixing assembly 90 is arranged on the bed board, and the fixing assembly 90 can generate magnetic attraction with the magnetic member. The first controller is connected to the battery 70 and the fixing assembly 90 respectively. The first controller controls the fixing assembly 90 to be powered on or off to adjust the magnitude of the magnetic attraction between the magnetic member and the fixing assembly 90. That is, when the fixing assembly 90 is powered on or off, the attraction between the magnetic member and the fixing assembly 90 can change, thereby adjusting the connection firmness between the restraint belt 80 and the bed board.

[0070] Furthermore, if Fig.12As shown, the fixing assembly 90 includes: a shell 91, a plurality of magnetic parts 92 and an electric plate 93. The shell 91 defines a receiving chamber, and the receiving chamber contains a fluid. The plurality of magnetic parts 92 are respectively arranged in the receiving chamber, and the electric plate 93 is connected to the battery 70 to form an electric field when powered on to control the direction of the magnetic part 92. That is to say, by regulating the electric field, the direction of the magnetic part 92 can be changed, so that the magnitude of the force between the magnetic part 92 and the magnetic attraction part changes. For example, when the positive pole of the magnetic part 92 is arranged relative to the positive pole of the magnetic attraction part, or when the negative pole of the magnetic part 92 is arranged relative to the negative pole of the magnetic attraction part, a repulsive force is generated between the two, which is conducive to opening the restraint belt 80. When the positive pole of the magnetic part 92 is arranged relative to the negative pole of the magnetic attraction part, or when the negative pole of the magnetic part 92 is arranged relative to the positive pole of the magnetic attraction part, an attractive force is generated between the two, which is conducive to improving the stability of the restraint belt 80. The magnetic member 92 generates magnetism only when it is powered on. When the power is on, an attractive force is generated between the magnetic member 92 and the magnetic attraction member. When the power is off, there is no force between the magnetic member 92 and the magnetic attraction member.

[0071] According to one embodiment of the present invention, Figures 9 to 11 As shown, the bed board includes: a plurality of first bed boards 54 and a plurality of second bed boards 56. The plurality of first bed boards 54 are arranged in sequence, each of which is movable along a first direction, and a side of each first bed board 54 close to the bracket 10 is an inclined surface. The plurality of second bed boards 56 are arranged in sequence and distributed between the first bed boards 54 and the bracket 10, the second bed boards 56 are movable along the first direction, and a side of each second bed board 56 close to the first bed board 54 is an inclined surface.

[0072] The bed board assembly 50 also includes an inclined top block 55, which is disposed on a side of the first bed board 54 close to the inclined top block 55, and the inclined top block 55 is movable along a second direction, and the second direction is perpendicular to the first direction. For example, when the first direction is the up-and-down direction and the second direction is the horizontal direction, when the inclined top block 55 moves along the horizontal direction, it can push the first bed board 54 upward, thereby driving the first bed board 54 to move upward. It should be noted that when the first bed board 54 moves along the first direction, the movable direction of the first bed board 54 can be limited by a limiting structure, and the specific limiting structure is not limited here.

[0073] Since each first bed board 54 can be controlled individually, the first bed board 54 corresponding to a certain part of the patient can be made slightly higher than other parts by adjusting the height of a certain first bed board 54. For example, the height of the patient's head or other parts that need to be raised can be raised.

[0074] The inclined lift block 55 is located between the second bed board 56 and the first bed board 54 to drive the first bed board 54 or the second bed board 56 to move along the first direction. That is, the inclined lift block 55 can not only adjust the position of the first bed board 54, but also adjust the position of the second bed board 56.

[0075] Furthermore, if Figures 9 to 11 As shown, the cross-section of the plane formed by the inclined lift block 55 along the first direction and the second direction is rhombus-shaped, that is, the movement of at least four nearby bed boards (two first bed boards 54 and two second bed boards 56) can be achieved through one inclined lift block 55.

[0076] According to one embodiment of the present invention, the medical transport bed 100 further includes: an injured position locator, a position information transmitter, and a second controller. The injured position locator is provided on the bracket 10 to obtain the injured position information of the patient. The position information transmitter is connected to the injured position locator to obtain the injured position information of the patient. The second controller is respectively connected to the position information transmitter and the inclined top block 55 to drive the corresponding inclined top block 55 to move along the second direction according to the injured position information. In other words, through the cooperation of the injured position locator, the position information transmitter, and the second controller, the height of a certain part of the patient can be automatically controlled, thereby improving the degree of automation.

[0077] In some specific embodiments of the present invention, the first slider 45 and / or the second slider 46 are detachably connected to the bed board and / or the slide rail assembly 40. For example, when the bed board is in the second state 52, the connection between the first slider 45 and the third slide rail 43 can be released, and the bed board can further rotate around point A with a larger rotation angle. When the bed board is in the third state 53, the connection between the second slider 46 and the fourth slide rail 44 can be released, and the bed board can further rotate around point B with a larger rotation angle.

[0078] In summary, the medical transfer bed 100 according to the embodiment of the present invention adopts the support 10, the support legs 20, the rollers 30, the slide rail assembly 40 and the bed board to cooperate with each other, which can not only realize the transfer of patients, but also improve the convenience of transfer and the comfort of patients.
