Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1 and 2, the present invention provides a medical flat car, which comprises a car body 1 and a transfer plate 2. The vehicle body 1 comprises a bed plate 11, a lifting frame 12, universal wheels 13, a lifting device 14 and a traction device 15. The bed plate 11 is a substantially rectangular plate structure for lying a patient, and the bed plate 11 includes a first side 111 and a second side 112 oppositely disposed. The lifting frames 12 are 4 in number and are arranged below the bed plate 11, and the 4 lifting frames 12 correspond to 4 corners of the bed plate 11 one by one, so that the bed plate 11 can be stably supported on the 4 lifting frames 12. There are 4 universal wheels 13, which are respectively arranged on the 4 lifting frames 12, so that the vehicle body 1 can move towards any direction. The lifting device 14 is disposed below the bed plate 11 and is used for adjusting the height of the bed plate 11. Specifically, the lifting device 14 drives the lifting frame 12 to move upwards or downwards, so as to drive the bed board 11 to move upwards or downwards, and thus, the height of the bed board 11 is adjusted. Or the lifting device 14 directly drives the bed board 11 to move upwards or downwards to adjust the height of the bed board 11, and the lifting frame 12 moves upwards or downwards along with the height of the bed board 11. A pulling device 15 is arranged on the second side 112, the pulling device 15 being detachably connected to the transfer plate 2, the pulling device 15 being capable of pulling the transfer plate 2 in a direction from the first side 111 towards the second side 112 when the pulling device 15 is connected to the transfer plate 2, so that the transfer plate 2 is moved onto the bed plate 11.

When a patient needs to be transported, the trolley body 1 is moved to one side of a sickbed, the direction and the position of the trolley body 1 are adjusted, and meanwhile, the height of the bed plate 11 is adjusted through the lifting device 14, so that the upper surface of the bed plate 11 is as high as the bed surface of the sickbed, and the first side 111 is attached to and aligned with the bed edge on one side of the sickbed; then, inserting the transfer plate 2 under the patient at the other side edge of the sickbed until the patient completely lies on the transfer plate 2; finally, the traction device 15 is connected to the transfer plate 2, and the traction device 15 draws the transfer plate 2 onto the bed plate 11. Therefore, the patient can be smoothly moved to the vehicle body 1, the vehicle body 1 is pushed, and the patient can be transferred to a target place. The whole operation process can be completed by only one person, and multi-person cooperative operation is not needed, so that the operation is simple and convenient. And, while moving, do not contact the patient directly, do not exert external force to the patient directly, but draw the transfer board 2 slowly, steadily through the draw gear 15, draw the transfer board 2 to the bed plate 11, thus realize the movement of the patient, therefore, will not cause the secondary injury to the patient, and, because do not contact the patient directly, can reduce the risk of cross infection. It should be noted that the transfer plate 2 may be inserted obliquely downward under the patient and then slowly laid flat and inserted inward. The insertion mode is simple and easy to operate, and is not easy to cause injury to patients. To increase patient comfort, a cushion (not shown) may be provided on the upper surface of the transfer plate 2.

Referring to fig. 1, baffles 113 are disposed at opposite ends of the bed plate 11. The barrier 113 prevents the patient from slipping out of the end of the vehicle body 1 when moving the vehicle body 1. To increase comfort, a cushion (not shown) may be provided on the inner side of the bezel 113. The inner side surface of the baffle 113 is provided with a guide groove 114, one end of the guide groove 114 located on the first side 111 is an open end (not shown), and one end of the guide groove 114 located on the second side 112 is a closed end (not shown). When the traction device 15 pulls the transfer plate 2, the opposite ends of the transfer plate 2 are respectively clamped into the corresponding guide grooves 114, and the guide grooves 114 can guide the movement of the transfer plate 2 and prevent the movement direction of the transfer plate 2 from deviating from the target direction. The closed end is arranged to limit the transfer plate 2 and prevent the transfer plate 2 from moving out of the second side 112.

It will be appreciated that in other embodiments not shown, the guide groove 114 may also be provided on the upper surface of the bed plate 11, and correspondingly, the lower surface of the transfer plate 2 may be provided with guide projections (not shown). When the traction device 15 draws the transfer plate 2, the guide protrusions are clamped into the corresponding guide grooves 114, and the cooperation of the guide protrusions and the guide grooves 114 plays a role in guiding the movement of the transfer plate 2.
