Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the scope of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

At present, in the transportation of a patient or a subject who is not convenient to move, a hospital staff is assisted in transportation by a transfer cart. However, most of the transfer carts usually employ a rigid driving mechanism for driving in order to facilitate the horizontal movement of the transfer board, so as to suspend the pressure-bearing member in the air by looking at the transfer board, so as to facilitate the transfer of the patient or the subject. When the movement of the transfer plate is blocked (such as impacting a flat bed or a patient or a person to be detected), the transmission parts inside the driving mechanism for driving the transfer plate are easy to generate rigid collision, so that the driving mechanism is damaged or blocked, and the service life of the transfer vehicle is not prolonged.

As shown in fig. 1 and 2, in one embodiment, a transfer cart is provided, which includes a supporting frame 100, a pressure-bearing member 200, a transfer plate 500, and a driving mechanism 600; the supporting frame 100 comprises an inlet side 110 and an outlet side 110, and the pressure bearing piece 200 is arranged on the supporting frame 100; the transfer plate 500 is movably arranged on the pressure bearing member 200; the driving mechanism 600 includes a flexible transmission member 610 and a driver 620, the flexible transmission member 610 is fixedly connected to the transfer plate 500, and the driver 620 is used for driving the transfer plate 500 to reciprocate in the in-out direction through the flexible transmission member 610.

When the above-mentioned car that shifts uses, utilize the cooperation of flexible drive spare 610 and driver 620, realize that flexible drive shifts board 500 and removes, when the removal that shifts board 500 is obstructed (if striking to flat bed or patient or by the person who detects), the flexible drive spare 610 of drive transfer board 500 can take place to warp, can cushion the impact force of shifting board 500 and being obstructed the production, and avoid the rigidity collision, and then can avoid actuating mechanism 600 impaired or card dead, be favorable to improving the life who shifts the car. Meanwhile, understandably, the driving mechanism 600 is not easy to be damaged or stuck, and the reliability of the operation of the transfer vehicle is guaranteed.

The "transfer plate 500" may be configured to transfer a patient or a subject, and the specific structure includes, but is not limited to, a plate-shaped structure.

In addition, most of the scanning beds of CT machines and MRI machines are curved beds at present. When a patient or a detected person who is inconvenient to move needs to be moved away from the curved bed, the traditional transfer vehicle (also called a transfer bed) is difficult to adapt to curved surface transportation because the transfer plate can only be horizontally fed. Therefore, the scanning equipment is usually carried by manpower, which not only has low carrying efficiency, but also has large carrying labor intensity, and is not beneficial to fully utilizing the scanning efficiency of the scanning equipment. In particular, when new crown epidemics and the like are encountered and the scanning device needs to be used frequently, the manual carrying mode is difficult to adapt.

Therefore, the traditional transfer trolley needs to be improved, so that the supporting surface can be inclined downwards, the transfer plate can be inserted downwards below the body of a patient or a detected person on the curved bed, the patient or the detected person on the curved bed can be conveniently carried by the transfer plate, the carrying efficiency is improved, the carrying labor intensity is reduced, the scanning capacity of the scanning equipment is matched, and the use frequency of the scanning equipment is improved.

As shown in fig. 1 to 4, based on any of the above embodiments, in an embodiment, the driver 620 is electrically driven, the pressure-bearing member 200 is movably disposed on the supporting frame 100, and the pressure-bearing member 200 includes the pressure-bearing surface 210; the transfer cart further includes a lifting mechanism 300 for lifting up the pressure receiving member 200 such that the pressure receiving face 210 is inclined downward in the entrance and exit side directions. In this way, when it is necessary to transfer a patient or a subject on the curved bed 900, the elevating mechanism 300 is operated to lift the pressure receiving member 200 such that the pressure receiving surface 210 is inclined downward toward the entrance side 110.

When the patient or the subject on the curved bed 900 needs to be transferred during the use of the transfer cart, the lifting mechanism 300 is operated to lift the pressure receiving member 200, so that the pressure receiving surface 210 is inclined downward toward the entrance side 110, and the transfer plate 500 provided on the pressure receiving surface 210 is also inclined downward toward the entrance side 110 (as shown in fig. 4). Thus, only the driver 620 needs to be controlled to act to drive the transfer plate 500 to be inserted downwards under the patient or the detected person on the curved bed 900, and then the driver 620 acts again to move the patient or the detected person into the transfer plate 500; alternatively, depending on the position where the patient or subject enters the transfer plate 500, the insert-move may be repeated a plurality of times so that the patient or subject can be moved completely onto the transfer plate 500. Finally, the pressure-bearing member 200 can be reset, so that the driver 620 drives the transfer plate 500 to move, and the patient or the detected person is transferred to the transfer cart, thereby realizing the transportation of the patient or the detected person of the curved bed 900.

Particularly, the transfer vehicle is applied to a scanning scene, can improve the carrying efficiency, and fully utilizes the scanning capability of scanning equipment to adapt to the situations of new crown epidemic situations and the like which need to use the scanning equipment at high frequency; meanwhile, the labor intensity of carrying the scanning equipment can be reduced, the number of people carrying detected persons can be reduced, and the human resources required by the scanning equipment can be reduced. And the driver 620 is electrically driven, which can further reduce labor intensity.

Meanwhile, it can be understood that, when the pressure bearing member 200 is not jacked up by the lifting mechanism 300 (i.e. when the lifting mechanism 300 is not actuated), the transfer plate 500 can be transversely fed to accommodate the transfer of a patient or a detected person with a horizontal bed surface, so that the transfer vehicle can accommodate both the transfer of the curved bed 900 and the transfer of the horizontal bed surface.

It should be noted that, specific implementations of the "lifting mechanism 300" include, but are not limited to, a telescoping mechanism, a jacking mechanism, and the like. And the power supply can be electric or manual.

It should be noted that the specific structure of the "pressure-bearing member 200" includes, but is not limited to, a pressure-bearing frame (i.e., a frame structure), a pressure-bearing plate (a plate structure), and the like.

On the basis of the above embodiments, in an embodiment, the pressure-bearing member 200 is rotatably connected to the supporting frame 100, and the supporting frame 100 is provided with a limiting portion 120 for supporting the pressure-bearing member 200. In this way, the pressure-bearing member 200 is rotatably connected to the supporting frame 100, so that the pressure-bearing member 200 is not displaced during the rotation process, and the patient or the subject can be safely transferred to the transfer cart. Meanwhile, the pressure-bearing member 200 is restrained and supported by the restraining part 120, so that the pressure-bearing member 200 can be automatically reset to a predetermined position, such as a horizontal position, so that the patient or the subject on the transfer plate 500 can be laid flat.

On the basis of any of the above embodiments, as shown in fig. 5, in an embodiment, the lifting mechanism 300 includes a lever 310 and a first driving unit 320, the lever 310 is rotatably disposed in the supporting frame 100, one end of the lever 310 abuts against the bottom wall of the pressure-bearing member 200, and the first driving unit 320 is configured to drive the lever 310 to rotate so as to jack up the pressure-bearing member 200. In this way, the pressure bearing member 200 is lifted up by the cooperation of the lever and the first driving unit 320, which is easy to implement. Meanwhile, the jacking force of the jacking pressure-bearing part 200 and the transfer plate 500 can be conveniently adjusted by utilizing the lever principle.

As an alternative, in one embodiment, the lever 310 is a labor-saving lever 310. Thus, the force applied to jack up the pressure-bearing member 200 and the transfer plate 500 can be reduced, and the labor intensity or the implementation difficulty can be further reduced.

Alternatively, as shown in fig. 6, in one embodiment, the lever 310 includes a roller 312 that abuts against the bottom wall of the pressure bearing member 200. Therefore, the friction between the lever and the pressure bearing piece 200 can be reduced, the change of the stress position generated when the pressure bearing piece 200 rotates can be adapted, and the transition is stable.

In addition to any of the above lever embodiments, as shown in fig. 7 and 9, in an embodiment, the first driving unit 320 includes an elastic member 322, one end of the elastic member 322 is connected to the supporting frame 100, and the other end of the elastic member 322 is connected to the other end of the lever 310, so that when the elastic member 322 is reset, the lever can jack up the pressure-bearing member 200. Therefore, the pressure-bearing part 200 can be jacked up only by elastic restoration of the elastic part 322, which is beneficial to improving efficiency and simple and convenient to operate.

It should be noted that the "elastic member 322" includes, but is not limited to, an extension spring, a compression spring, a gas spring, elastic gel, a spring plate, and the like. The selection may be made according to a restoring force required for the lever to jack up the pressure bearing member 200.

Such as a tension spring, is provided at an end remote from the pressure bearing member 200. Or a compression spring, an elastic colloid or a spring plate is arranged at one end close to the pressure-bearing part 200.

On the basis of the above-mentioned embodiments, as shown in fig. 5, in one embodiment, the transfer cart 10 further includes a reset mechanism 400, and the reset mechanism 400 is used for resetting the pressure-bearing member 200 or the lever 310 so that the elastic member 322 is compressed or stretched. In this way, the elastic member 322 can be in a non-reset state by using the reset mechanism 400, so that the pressure-bearing member 200 can be in a non-jacked reset state, that is, the transfer plate 500 can move laterally at this time, so as to be convenient for adapting to the transfer of the patient or the subject on the horizontal bed. The elastic member 322 can be elastically restored by only unlocking the restoring mechanism 400, so that the pressure-bearing member 200 is jacked up, and the operation is simple.

On the basis of the above embodiments, as shown in fig. 7 to 12, in an embodiment, the reset mechanism 400 includes a first transmission member 410 and a second driving unit 420 capable of self-locking, one end of the first transmission member 410 is connected with the lever 310 or connected with the pressure-bearing member 200, and the second driving unit 420 drives the pressure-bearing member 200 or the lever 310 to reset through the first transmission member 410, so that the elastic member 322 is compressed or stretched.

Alternatively, in one embodiment, the height of the upward movement of the lever 310 may be adjustable, thereby allowing the angle of inclination of the pressure bearing face 210 to be adjustable. The specific implementation manner may be various, including but not limited to the connection position between the elastic member 322 and the lever 310 being adjustable, or the connection position between the first transmission member 410 and the lever 310 being adjustable, or the length of the lever 310 being adjustable, etc.

Based on the above embodiments, as shown in fig. 7, fig. 8 and fig. 10, in one embodiment, the first transmission member 410 is a flexible member, the second driving unit 420 includes a telescopic end 402, and the telescopic end 402 is fixedly connected to the flexible member; alternatively, the second driving unit 420 includes a rotation end (not shown) fixedly connected with the flexible member. In this way, the flexible member can be used for stretching or rotating power, so that the lever rotates upwards, the elastic member 322 can automatically reset, and the lever jacks up a patient or a detected person; meanwhile, when the patient or the detected person can move into the pressure-bearing member 200 along with the transfer plate 500, the flexible member can deform and is not interfered by the second driving unit 420, so that the pressure-bearing member 200 can be automatically pressed down, the lifting mechanism 300 does not need to be frequently operated in the process, the operation steps are simplified, and the transfer efficiency is improved. That is, after the pressure-bearing member 200 is jacked up, when the pressure received by the pressure-bearing member 200 is greater than the reset force of the elastic member 322, the pressure-bearing member 200 can be automatically pressed down, so that the elastic member 322 is in a non-reset state; the pressure can be automatically jacked up the pressure bearing member 200 after the pressure is removed, so that the insertion-moving-in step can be repeated, and the patient or the detected person can move into the position right above the pressure bearing member 200.

Specifically, in the present embodiment, as shown in fig. 7 to 10, the flexible member is a brake cable; the second driving unit 420 includes a link assembly 421 disposed on the supporting frame 100 and a swing link 422 for driving the link assembly 421 to move, the link assembly 421 is capable of self-locking, and the link assembly 421 is provided with a telescopic end 402. Thus, the swing rod 422 drives the connecting rod assembly 421 to move, so that the telescopic end 402 can retract, and further the brake cable pulls the lever 310 to move downwards, the lever 310 resets, the pressure-bearing member 200 also resets, and the connecting rod assembly 421 can be self-locked at the moment, and the elastic member 322 is in a non-reset state (which can bear the weight of a patient or a detected person and is in a non-reset state, namely, is pulled or pressed). And the oscillating bar 422 drives the connecting rod assembly 421 to move reversely, so that the telescopic end 402 can extend out, and the lever 310 can move upwards under the reset action force of the elastic element 322 to jack up the pressure-bearing member 200.

Alternatively, as shown in fig. 11, and with reference to fig. 7 and 9, in another embodiment, the flexible member is a brake cable; the second driving unit 420 includes a first nut 423 slidably disposed on the supporting frame 100, a first screw 424 rotatably disposed on the supporting frame 100, and a first hand piece 425 driving the first screw 424 to rotate, the first screw 424 is in transmission fit with the first nut 423, and the telescopic end 402 is disposed on the first nut 423. Therefore, the first hand-operated member 425 drives the first screw rod 424 to rotate, so that the telescopic end 402 can move along with the first nut 423 and pull the brake cable to retract, the lever 310 is further pulled to move downwards, the lever 310 resets, the pressure bearing member 200 also resets, the first screw rod 424 and the first nut 423 can be self-locked at the moment, and the elastic member 322 is in a non-resetting state. The swing rod 422 drives the first screw rod 424 to rotate in the opposite direction, so that the telescopic end 402 can extend out along with the first nut 423, and the lever 310 can move upward under the reset action of the elastic member 322 to jack up the pressure-bearing member 200.

Alternatively, as shown, the flexible member is a brake cable; the second driving unit 420 is an electric telescopic device, and the transfer cart further includes a controller (not shown) electrically connected to the second driving unit 420 and the driver 620 to control the operation of the second driving unit 420 and the operation of the driver 620. In this way, the controller can control the second driving unit 420 and the driver 620 to perform the angle adjustment of the pressure-bearing surface 210 and the motion control of the transfer plate 500. The operator can realize the control by touching or pressing the control key on the controller, which is beneficial to reducing the labor intensity.

It should be noted that the controller includes, but is not limited to, a PLC controller, a control panel, and the like.

In combination with the above embodiments, when the elastic member 322 is an extension spring, the brake cable is connected to an end of the lever 310 near the pressure-bearing member 200. At this time, the brake cable is released, and the elastic member 322 can be reset to move the lever 310 upward to jack up the pressure bearing member 200; and pulls the brake cable, so that the lever 310 moves downward, the elastic member 322 is in a non-reset state, and the brake cable is locked by the second driving unit 420, so that the pressure bearing member 200 and the lever 310 are in a reset state.

It should be noted that the specific implementation manner of the "rotating end" of the second driving unit may be implemented with reference to the winding and unwinding device, or implemented by using a motor and a reduction gearbox.

Of course, in other embodiments, the reset mechanism 400 may be a locking structure, and in the locking state, the pressure-bearing member 200 or the lever 310 can be locked in the reset state; in the unlocked state, the pressure receiving member 200 and the lever 310 can move upward by the restoring force of the elastic member 322. Specifically, the reset mechanism 400 is a dial plate rotatably disposed on the supporting frame 100, and when the dial plate rotates to a locking state, the pressure-bearing member 200 can be locked on the supporting frame 100; when the paddle is rotated to the unlock state, the pressure receiving member 200 may be rotated upward by the restoring force of the elastic member 322 such that the pressure receiving face 210 is inclined downward with respect to the entrance and exit side 110.

Of course, in other embodiments, the lifting mechanism 300 is one of a rack and pinion telescoping mechanism, a lead screw first nut 423 telescoping mechanism, a link telescoping mechanism, or a jack. In this way, the pressure receiving member 200 can be lifted up.

The telescopic device includes, but is not limited to, hydraulic rods, pneumatic rods, linear motors and other devices capable of directly providing telescopic power.

In addition, the number of the "lifting mechanisms 300" or the number of the levers in any of the above embodiments is not limited herein, and the levers may be rotated according to actual needs.
