RÉSUMÉ
Objective To explore the clinical effect of new type rectal cancer radiotherapy individualized fixation device in the radiotherapy of rectal cancer. Methods From June 2015 to December 2016,60 patients with rectal cancer who accepted the external irradiation in Zhejiang Tumor Hospital were divided into two groups by random number table method. A group(31 cases) received new type rectal cancer radiotherapy position fixation devices with thermoplastic film. B group(29 cases) received simple foam pad with thermoplastic film. Before each treatment,Cone beam CT(CBCT) scan was conducted. The applied CBCT image and the planned reconstruction image were compared in the direction of X(left and right),Y(upper and lower)and Z(front and rear) axis. The setup error was recorded, and the correlation between the two groups was analyzed. Results The average setup error of patients in A group in X (left and right),Y(upper and lower),Z(front and rear) axis were (1. 61 ± 0. 18)mm,(1. 82 ± 0. 13)mm,(1. 91 ± 0. 11)mm,respectively. The average setup error of patients in B group in X(left and right),Y(upper and lower),Z (front and rear) axis were (2. 22 ± 0. 13)mm,(2. 43 ± 0. 14)mm,(2. 36 ± 0. 13)mm,respectively. There were statistically significant differences between the two groups(t=14. 958,17. 501,11. 283,all P＜0. 001). Conclusion The new type of rectal cancer radiotherapy position fixing device is more comfortable than the simple foam pad,and the setting error is smaller than the simple foam pad.
RÉSUMÉ
Objective To design a sitting posture fixation device for the ultrasonic imaging of baby hip joint dysplasia.Methods The device was composed of a riser,a fixation base,No.1 holding plate,No.2 holding plate,a baby fixation plate and two detection windows.The two holding plates made the baby's spine and femurs form a right angle at the sitting posture,so that the standard posture was obtained for hip joint ultrasonic imaging.The detection windows facilitated to gain the optimal image for the both sides of the hip joint.Results The device contributed to acquiring baby hip joint image rapidly with high quality and decreased examination time.Conclusion The device can be used for the massive screening of developmental hip joint abnormality.
RÉSUMÉ
A convenient fixing device for ankle vein infusion was developed and manufactured, that is beneficial to the patients not suitable for venous infusion in both arms. The device can effectively prevent the infusion needle slipping outside the vein and the drug liquor exosmosis occurs causing local swelling and pain, etc; it also can effectively reduce the workload of nurses for unnecessary to perform repeated venous punctures, thus the working efficiency of nurses is also elevated.
