Examination couch with protective device

Abstract

The invention discloses an examination couch with a protective device, which comprises a horizontal part and a vertical lift part, wherein a bottom cover is arranged under the horizontal part, the edge of the upper part of the bottom cover is provided with touch sensors, each touch sensor is connected with a drive motor of the vertical lift part so as to control the rotation of the motor, and the touch sensors are microswitches. The examination couch with the protective device, which is provided by the invention, is provided with the touch sensors at the edge of the upper part of the mobile bottom cover. The bottom cover can be lifted so as to trigger the touch sensors when the design resistance of the touch sensor overcomes the gravity of the bottom cover, and the touch sensors immediately send blackout signals to the vertical motor to stop the rotation of the motor so as to stop the vertical motion of examination couch, so that the examination couch as well as devices and maintenance staffs capable of being pressed by the examination couch can be protected to the maximum extent. Moreover, the examination couch with the protective device has the advantages of lower design cost, simplicity and reliability in function, and easiness in maintenance.

Description

technical field [0001] The invention relates to an examination bed, in particular to an examination bed with a protection device. Background technique [0002] Medical equipment, including MR CT, PET-CT, linear accelerators, etc., all require an examination bed to support the patient, and it is necessary to realize the movement of each degree of freedom of the examination bed. There is a large part of the space under the horizontal part of the bed that is not needed for the bed. In the clinical application process, there may be other equipment, such as wheelchairs or small auxiliary equipment such as mobile ventilators. Carefully push into the lower part of the horizontal part of the hospital bed, even during the maintenance process, some maintenance personnel may be in the lower part of the horizontal part of the hospital bed. At this time, if the operator executes the vertical movement of the hospital bed downward, it is likely to cause damage to the hospital bed itself an...

Problems solved by technology

[0003] The existing bed protection design for CT or MR examination beds mainly realizes the vertical movement protection function of the bed board through the current limiting of the motor. When the bed is moving downward and vertically, when other equipment or maintenance personnel are still in the lower part of the bed accidentally, The current increase caused by the motor control sensing the extra movement resistance of the hospital bed triggers the current limiting protection function to stop the movement of the hospital bed. This design will require too much resistance to trigger the protection function, and usually requires a resistance of hundreds of Newtons or even thousands of Newtons. If the protection function is triggered, there is a risk that the bed itself will be damaged, the equipment accidentally pressed by the bed will be damaged, or the maintenance personnel will be injured.
