Abstract

The invention relates to medical equipment and allows for improved operability. To do this, in the device, when carrying out the transfer of the patient's rack to the bed, the cross-shaped mechanism 10 for raising and lowering, pivotally connected through the axles 14 to the forks 3, which are pivotally connected through the axles 13 to the frame 2, is lowered. The sheet 16, fixed in the clips 8, hangs above the platform 1. The clips 8 along the guides 7 are moved towards the bed. The platform 1 continues to fall down, and together with it the frame 2 with the supports 6 and the guides 7. After the patient is fully placed on the bed, the mechanism 10 is turned off, the clamps 8 release the sheet 16. The cart is also equipped with brackets 11 with wheels 12 fixed on the forks 3 rigidly or pivotally with the possibility of fixation. In this case, the pivot point of the wheel 12 is vertically displaced upwards relative to the pivot point of the wheel 5. The guides 7 can be pivotally connected to the uprights 6. 2 hp f-ly, 5 ill.

Description

The invention relates to medical equipment, in particular to the transportation of patients after surgery.

The aim of the invention is to improve the usability.

Fig.1 shows the cart, the initial state; FIG. 2 is the same with the raised and lowered mechanism; fig.Z - the same, right view; Fig. 4 is a diagram of the relative position of the wheels of the fork and the wheels of the brackets when transferring the patient from the trolley to the bed; Fig. 5 is a diagram of the mutual position of the fork wheels and the bracket wheels when the patient is transferred from the bed to the trolley.

The cart contains platform 1, frame 2, forks 3, on the lower part 4 of which wheels 5, racks 6, guides 7, clamps 8 with rollers 9, cross-shaped mechanism 10 for lifting and lowering, brackets 11 with wheels 12, axes 13 and 14 are placed. , handles 15, sheet 16, The cart is placed on the supporting surface (on the floor) 17, on which the bed 18 is installed. Guides 7 can be fixed on the uprights 6 by means of a hinge 19,

Platform 1 is connected by means of a cross-shaped mechanism 10 for lifting and lowering through axles 14 with forks 3, which are placed on axles 13 mounted in frame 2. The lower part 4 of forks 3 can be rotated and locked. On the uprights 6, which are fixedly mounted on the frame 2, there are guides 7, on which are mounted, clamps -8 with the possibility of their movement along the guides 7 with the help of rollers 9. Brackets 11 are fixed on the fork 3, on the ends of which wheels 12 are placed The handle 15 controls the clamp 8, in which the sheet 16 is fixed, the cart is mounted on wheels 5, which are placed on the supporting surface 17, on which the bed 18 is mounted, the brackets II and the guides 7 can be fixed respectively on the forks 3 and racks 6 using hinges 19,

The point of support of the wheel 12 is shifted vertically upwards relative to the point of support of the wheel 5,

The cart works as follows.

The patient, for example, after the operation, is placed on platform 1, having previously placed a sheet 16 on it, and is transported to the ward. The cart is installed near the bed 18 and the lower parts 4 of the forks 3 are fixed (clamps not shown) in the position shown in FIG. 1, solid

g line. The bracket 11 and guides 7 are rotated around the hinges 19 so that they are in a plane perpendicular to the longitudinal axis of the carriage (see Fig. 3), and fix them in

5 this position. Then, the ends of the sheet 16 are fastened in the clips 8, acting on the latter with the handles 15. The sheet 16 can be fixed in the clips and before placing the patient on the board

0 form 1, which ensures the softening of possible jolts and impacts when transporting the patient to the ward,

Using a drive (not shown) lowered the cross-shaped mechanism 10,

5, as a result (see FIG. 2), the left fork 3 rotates around axis 13 against, and the right clockwise, while platform 1 moves down, the patient hangs on a simple

no, but frame 2 does not lower. To lower the frame 2, it is necessary that the fork 3 rotates around an axis 13 by an angle greater than the double angle formed by a perpendicular that is lowered from the center of the axis 13 onto the bearing surface 17 and straight through the center of the axis 13 and the touch point of the wheel 5 with supporting surface. In FIG. 4, the double angle is enclosed between two positions of the wheel 5, which are shown by solid and dashed lines,

After the patient hangs on the sheet, the clamps 8 with the sheet 16 and the patient are moved along the guides 7 towards the bed 18, Due to the fact that the fulcrum of wheel 12 is displaced relative to the fulcrum of wheel 5, then when you turn the fork 3 the wheel 12 will be above the wheel 5 at a certain distance. By turning the fork 3 at a double angle, this distance will reach a. As soon as the center of gravity, when the patient moves toward the bed, will move the pivot point of the wheel 5 of the carriage, wheel 12 will become entangled by the amount a, and the left wheel (see, FIG. 3) wheel 5 rises,

and guides 7 tilt towards bed 18, which will reduce the patient’s movement force,

During further operation of the cross drive mechanism 10, the platform 1 will continue to lower and the forks 3 will rotate in the indicated directions. As soon as they pass the double angle shown in Fig. 4, the frame 2, and together with it the stands 6, the guides 7 and the patient with the sheet 16 are lowered. As soon as the patient is fully lowered onto the bed, the drive of the cross-shaped mechanism 10 and handles 15 are turned off the sheet 16 is released from the clamps 8. After that, using a drive, the cruciform mechanism 10 is lifted, the patient remains on the bed, and the heat sink takes up its original position.

If the patient is required to be taken out of bed, the forks 3 are placed in the position shown in dashed line in Fig. 1. Then, when the forks 3 are rotated, the wheel 5 will be above the wheel 12 (see Fig. 5), therefore when lowering the cart, the inclination of the guides 7 will occur towards the cart. After complete lowering, the ends of the sheet 16 are fastened in the clamps for 8 hours and the cross-shaped mechanism 10 is lifted up. During the lifting process, the indicated direction of the tilt of the guides is maintained, which reduces the effort to move the patient.

go to the side of the cart. After tsgo as forks 3 will occupy the initial position, the patient will be on the platform 1 ready for transportation.
