Parameter Evaluation and Application Demonstration of a New Type of Blood Vacuum Tube Cap Opening and Closing Machine
Background: We aimed to evaluate the basic performance and basic parameters of a new type of blood vacuum tube cap opening and closing machine for further application.
Methods: From July 2013 to March 2018, 110, 000 cases involved in the clinical trials in Third People's Hospital of Dongguan City were selected as the instrument group, and 10,000 cases were selected as the manual operation group. The application demonstration and instrument performance assessment were performed by five units. Unified evaluation indicatory system and the standard of assessment were set up. The instrument assessments and demonstration tests were carried out by these 5 units. Finally, the basic parameters of the instrument were analyzed and compared.
Results: The new instrument had excellent performance, and thirty parameters were excellent. Five patents had been granted already. There were no differences between the instrument groups in different units, and among different units. However, there were some differences in the manual operation group between different units. The average cap opening time was 21 "04 in the instrument group, and 152" 48 in the manual operation group (P<0.05); the cap closing time was 18 "56 in the instrument group, and 104"24 in the manual operation group (P<0.05). The instrument group outperformed the manual operation group in cap closing time, pollution rate, spill rate and failure rate (P<0.01). The design of the instrument was original.
Conclusion: This blood vacuum tube cap opening and closing machine can perform a wide variety of functions, and it is stable, intelligent and superior to manual operation. More efforts need to be made for the industrialization of this instrument.
