Problems solved by technology

[0004] The height detection technology provided by the prior art usually uses the position information of the slider 330 or 331 moving in the horizontal direction and the structural size of the driving mechanism to calculate the height position of the lifting platform. This detection technology is to indirectly calculate the height of the lifting platform position, the calculation accuracy is not high, and it is impossible to provide accurate judgments for photography operators

Embodiment Construction

[0040] see figure 2 , which provides a structural schematic diagram of Embodiment 1 of a patient lifting platform for the present invention.

[0041] The patient lifting platform provided by Embodiment 1 of the present invention includes a bottom frame 1 , a top frame 2 , a driving mechanism 3 and a height detection mechanism 4 . In the embodiment of the present invention, the top frame 2 may be a platform for supporting the patient.

[0042] The driving mechanism 3 at least includes a first swing link 31 and a second swing link 32 . A first moving part 330 is rotatably mounted on one end of the first swing link 31 . Here, "rotatably installed" means that one end of the first swing link 31 is rotatably connected to the first moving part 330 . The first moving part 330 can move horizontally on the top frame 2 , so that the first swing bar 31 can move horizontally on the top frame 2 . The other end of the first swing link 31 is rotatably connected to the bottom frame 1 .

Abstract

The invention provides a patient lifter which comprises a bottom frame, a top frame, a drive mechanism and a height detection mechanism. The height detection mechanism comprises a stay rope, a rope wheel and an elastic component, wherein the stay rope is connected with the elastic component to wind around the rope wheel. A detection sensor for detecting the rotation angle of the rope wheel is arranged on the rope wheel. A movement component of a first oscillating bar and a movement component of a second oscillating bar do horizontal movements on the top frame and the bottom frame when the top frame moves along a vertical direction, and the stay rope drives the rope wheel to do rotational motion, so that the detection sensor detects the rotation angle of the rope wheel to further detect the height value of the top frame moving along the vertical direction. The height change value of the patient lifter can be reflected accurately.

Description

technical field [0001] The invention relates to the field of medical radiography systems, in particular to a patient lifting platform used in medical radiography. Background technique [0002] see figure 1 , in the prior art, during medical radiography, the patient lifting table supporting the patient is usually driven up and down by an X-frame driving method. In simple terms, the lifting platform includes a bottom frame 1 and a top frame 2, and an X-shaped driving mechanism. The X-shaped driving mechanism includes a swing rod 31 and a swing rod 32, wherein one end of the swing rod 31 is provided with a slide block 330, and the swing rod 32 One end of one end is provided with slide block 331, and this slide block 330 and slide block 331 move horizontally on the guide rail of bottom frame 1 and top frame 2, and the other end of swing bar 31 and swing bar 32 is fixedly arranged on bottom frame 1 and top frame respectively. 2 on. [0003] In order to enable the photography o...
