Description

A patient transport trolley for CT machine

technical field

The utility model relates to the technical field of mobile devices, in particular to a patient transfer trolley for a CT machine.

Background technique

When doing CT for critically ill patients, it is necessary to support or carry the patient from the lathe bed to the CT bed to lie down, which is easy to cause secondary injury to the critically ill patient, and even seriously affects the patient's life safety.

Utility model content

The utility model aims at the defects of the above-mentioned prior art, and proposes a mobile trolley that can put the patient on the CT bed without manual handling.

In order to solve the above technical problems, the utility model proposes the following technical solutions:

A patient transfer trolley for CT machines, comprising an upper frame and a lower frame that are both U-shaped and have the same U-shaped opening direction, a bed board placed on the upper frame, wheels, and two arms arranged under the upper frame. The two lifting mechanisms of the upper frame body are respectively fixed with guide rails under the two arms of the upper frame body, and the two arms of the lower frame body are respectively equipped with freely rotatable screw rods, and the surface of the screw rods has two opposite thread directions In the threaded area, the lifting mechanism includes two connecting rods that intersect each other and are hinged at the crossing parts. The upper ends of the two connecting rods are slidingly connected with the guide rails through sliders, and the lower ends of the two connecting rods are respectively threaded with the two threaded areas of the screw rod through nuts. . When the screw rod does not rotate, the distance between the two nuts is fixed, and the lifting mechanism maintains a certain height to support the upper frame, the bed board and the patient lying on the bed board. When the screw rod rotates, the two nuts approach or move away from each other, changing the angle and vertical height of the two connecting rods, thereby driving the upper frame and the bed board to lift. The patient lies on the bed, and the height of the upper frame is higher than that of the CT bed. Push the trolley so that the CT bed enters the bottom of the trolley through the U-shaped opening of the trolley. Lower the lifting mechanism of the trolley. When the bed board falls on the CT bed, the lifting mechanism continues to descend a certain distance until the upper frame is separated from the bed board, and then pulls out the trolley. When it is necessary to transfer the patient from the CT bed to the trolley, perform the opposite action to the above.

The beneficial effect of the utility model is that: patients with inconvenient movements, especially those who are seriously ill, can lie on the CT bed stably, avoiding secondary injury to the patient when carrying the patient; lifting and lowering is realized by changing the angle of the cross connecting rod, and the structure is simple ; The screw rod has two threaded areas with opposite thread directions, which ensures the synchronization of the end movement of the connecting rod and realizes the vertical movement of the lifting mechanism and the bed board.

Further, the four corners of the upper frame and the lower frame are connected by four freely telescopic rods, and the telescopic rods can maintain the stability of the upper frame to a certain extent, and can also play a role in the lifting of the upper frame. guiding role.

Further, the wheels are universal wheels or a combination of universal wheels and directional wheels, which are convenient for changing direction when pushing the trolley.

Further, one end of the screw rod is fixedly connected with a rocker, and shaking the handle drives the screw rod to rotate and controls the lifting mechanism to go up and down.

Furthermore, pins are provided on the crank handle, and a disc with several through holes evenly distributed along the circumference is fixed on the lower frame, and the pins can be inserted into the through holes of the disc to fix the crank handle to prevent accidental shaking. The handle causes the lifting mechanism to rise and fall.

Furthermore, two bearings are installed on the lower frame to make the rotation of the screw more flexible.

detailed description

The embodiment of the patient transfer trolley for CT machine of the present invention will be described in detail below in conjunction with FIGS. 1-3 .

As shown in Figure 1, a patient transfer trolley for CT machines includes a bed board 1, an upper frame body 2 and a lower frame body 3 that are U-shaped and have the same U-shaped opening direction, wheels 8, and a device that supports and drives the bed board 1 up and down. Lifting mechanism. A guide rail 6 is respectively fixed under the two arms of the upper frame body 2 , and two bearings 10 are respectively installed on each arm of the lower frame body 3 , and the bearings 10 are equipped with screw mandrels 5 . The screw rod 5 includes two threaded areas with opposite thread directions, and a crank handle 9 is provided at one end of the screw rod 5 . The bed board 1 is placed on the upper frame body 2, and the wheels 8 are installed on four corners of the lower frame body 3 respectively, and the wheels 8 are universal wheels or a combination of universal wheels and directional wheels. In order to increase the stability of the upper frame body, the four corners of the upper frame body 2 can also be fixedly connected with the four corners of the lower frame body 3 through four freely expandable telescopic rods 4 .

The lifting mechanism is installed between the arm of the upper frame body 2 and the arm of the lower frame body 3, and one is respectively installed on both sides of the trolley. Each elevating mechanism comprises two connecting rods 14 that intersect and are hinged at the crossing positions. The slider 11 is slidably connected with the guide rail 6, and the two nuts 12 are respectively arranged in two threaded areas of the screw rod 5 with opposite thread directions. When the screw mandrel 5 does not rotate, the distance between the two nuts 12 is constant, and the lifting mechanism maintains a certain height, supporting the upper frame body 2, the bed board 1 and the patient lying on the bed board 1. When the crank handle 9 is shaken to rotate the screw mandrel 5, the two nuts 12 approach or move away from each other, changing the intersection angle and vertical height of the two connecting rods 14, thereby driving the upper frame 2 and the bed board 1 to lift. The rocking handle 9 is provided with pins (not shown in the figure), and the lower frame body 3 is fixed with a disc 15 that is uniformly distributed along the circumference, and the pins can be inserted into the through holes of the disc 15 to make the Rocking handle 9 is fixed, prevents from touching rocking handle 9 by mistake and causes lifting mechanism to go up and down.

As shown in Figure 2, the patient lies on the bed board 1, the height of the upper frame 2 is higher than the CT bed 13, and the trolley is pushed to make the CT bed 13 enter the bottom of the trolley through the U-shaped opening of the trolley. As shown in Figure 3, shake the crank handle 9 to lower the elevating mechanism of the trolley. When the bed board 2 falls on the CT bed 13, the elevating mechanism continues to descend a certain distance until the upper frame body 2 is separated from the bed board 1, and then the trolley is drawn out, making it inconvenient to move. Especially seriously ill patients are placed on the CT bed 13 smoothly together with the bed board, so as to avoid secondary injury to the patient when the patient is moved. When it is necessary to transfer the patient from the CT bed 13 to the trolley, perform the opposite action to the foregoing.

What have been described above are only some embodiments of the present utility model. For those skilled in the art, without departing from the inventive concept of the present utility model, some modifications and improvements can be made, and these all belong to the protection scope of the present utility model.
