Holding and stabilizing the cryoprobe is important for bronchoscopic cryotherapy in combination with endoscopic procedures successfully and precisely. This study aimed to develop and evaluate the use of the “Rama Chest Cryo Arm” device for bronchoscopic cryotherapy. Purposive sampling was used to recruit the 16 participants using this procedure at a tertiary hospital. The sample consisted of 3 nurse bronchoscopists
and 13 bronchoscopists. Research instruments included 1) the device “Rama-Chest Cryo Arm” 2) the data collection questionnaires, and 3) the evaluation form for using the device. The data were analyzed with descriptive statistics. The results showed that the mean score of total four aspects of the sample on the “Rama Chest Cryo Arm” device was on the highest level. The value of the “Rama Chest Cryo Arm” device was rated as the highest, followed by the usability, safety from contamination, and purpose relevancy, respectively. Therefore, the “Rama Chest Cryo Arm” device could be used as a choice at hospitals providing the bronchoscopic cryotherapy procedure.
