Innovative design and experimental study of novel non-magnetic manual patient transfer vehicle
Since both the patients and the devices in the MRI room are difficult to transfer and demanding in environmental conditions,in this article a novel non-magnetic manual patient transfer device is designed.Firstly,based on the process of patient transfer,the working principle of the single-layer single-module open-belt transfer is proposed,the corresponding clutch mecha-nism is set up,and the analysis is conducted on the patient transfer vehicle's motion principle.Secondly,the motion structure of the transfer model is worked out;such problems as the linear speed matching between the moving panel and the transfer belt on one hand and the medical staff's operating force on the other hand are solved,when the one-stage gear transmission is added on both the transfer belt's transmission chain and the moving panel's transmission chain respectively.Finally,the prototype is de-veloped;then its performance,carrying capacity and requirement in the environmental conditions are tested.The results show that the transfer vehicle,with the carrying capacity of 113 kg,can work normally in the MRI room,which meets the requirements of both medical staff and patients.
