RESUMO
Objective To develop a supporting pole for medical detachable camouflage net at field conditions to enhance the timeliness of battlefield camouflage of deployable units such as medical tent.Methods The pole had a dumbbell-shaped,hollow and columnar structure,which was composed of a base,a pole body and a terminal disc.The pole body consisted of internal and external parts.The external part had a vertical opening at its top and screw thread at its side wall,which was equipped with a binding bolt.The terminal disc had a circular structure and a 20 cm outer diameter,which was fixed 10 cm under the top of the internal pole to support the net.The base had a center hole and a sleeve to hold the lower part of the external pole to immobilize the supporting pole.Results The supporting pole decreased the deployment time of the camouflage net from 5 min to 2 min and the withdrawal time from 4 min to 1.5 min,and enhanced the timeliness of all-element deployment of mobile medical unit during field practical training.Conclusion The supporting pole meets the tactical requirements for deployment,storage,transport and robustness,and thus is worthy promoting in medical unit.
