Foldable ladder for CT (computed tomography) examination couch

Abstract

The invention discloses a foldable ladder for a CT (computed tomography) examination couch, and belongs to the technical field of medical apparatus and instruments. The foldable ladder comprises a plurality of levels of steps. The multiple levels of steps are parallelly arranged, cross connecting rod groups are symmetrically arranged on two sides of each step and comprise a plurality of connectingrods which are hinged to one another in a cross manner, parallelogram structures are formed by the connecting rods which are hinged to one another in the cross manner, a horizontal vertex of each parallelogram structure is hinged to one of the multiple levels of steps, another horizontal vertex of each parallelogram structure is slidably connected with the step among the multiple levels of steps,and the every two corresponding horizontal vertexes are hinged points of the hinged ends of the two corresponding connecting rods. The foldable ladder has the advantages that the heights of the stepsmounted on the cross connecting rod groups can be adjusted by the cross connecting rod groups, identical distances between the multiple levels of steps can be guaranteed, patients can conveniently get on and out of the CT examination couch, and the problems of easy faults of examination couches and influence on the service lives of the CT examination couches due to the fact that the CT examination couches need to continuously ascend and descend during examination in the prior art can be solved; the examination time can be saved, and the examination efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a foldable ladder for a CT examination bed. Background technique [0002] The progress of medicine is inseparable from the development of medical devices, especially large medical devices, such as the well-known CT examination. With the continuous upgrading of CT, CT has been widely used in clinical examinations and has become a diagnostic tool for clinicians. The test of choice for many diseases. [0003] In the daily CT examination work, it is found that it is extremely inconvenient for many patients who need to be examined to go up and down the examination bed, especially the elderly patients. The current common practice is to lower the examination bed to make it easier for patients to go up and down, but the problem is that the manufacture of the examination bed in today's high-end spiral CT requires extremely precision and precision.

Problems solved by technology

[0003] In the daily CT examination work, it is found that many patients who need to be examined are extremely inconvenient when getting on and off the examination bed, especially elderly patients.

The current common practice is to lower the examination bed to make it easier for patients to go up and down, but the problem is that the manufacture of the examination bed in today's high-end spiral CT requires extremely precision and precision. Repeated lifting and lowering of the examination bed will significantly increase the failure rate, which will cause Delay in equipment inspection timeliness and increase in maintenance costs; on the other hand, repeated lifting and lowering of the examination bed greatly delays time and greatly prolongs the waiting time for waiting patients
