ABSTRACT
Objective To study the reference range of the urine analyzer and the target value of the common quality control object.Methods The reference ranges of urine analyzer test items from different mnanufacturers were investigated,and laboratory bias proportion was used as an indicator of the evaluation of the target value scheme.EQA raw data of Guangxi clinical examination center in 2014 were analyzed.Results The target value ranges of pH,specific gravity,bilirubin and nitrite were found reliable,while the ones for WBC,URO,RBC,ketone body,glucose and protein needed improving.Conclusion The target values and evaluation indexes of EQA have to be reselected for mutual recognition of the results.
ABSTRACT
The components and the principles of laser treatment instrument of YAG dual wavelength in intelligent Q switch are introduced in this paper.By the application of microprocessor technology,this instrument autocontrols the energy of pulse laser and pulse frequency,then the laser of specific wavelength is introduced to the skin by the light guide arm for beauty and related treatment.
ABSTRACT
This paper presents the components and the principles of an internal electrohydraulic lithotripter.Cooperating with the cystoscope,the lithotripter introduces the high-pressure discharge pulse into the bladder through the microelectrode.Then the little,easily-moved stone is targeted,and the re-discharge of the lithotripter 5mm away from the stone results in the shock wave to perform lithotritization.
ABSTRACT
Medical treatment facility(MTF) is the equipment of diagnosis and therapy of patients in medical service.The quality of MTF is directly related to the life safety of people.So it is very important to recognize and discuss the maintainability using overall quality standpoint.This standpoint is set out to satisfy the need of patients,reflect the need ability characteristics of MTF or medical treatment service.To guarantee the quality not only designs and produces quality but also is the very important means to confirm the quality.
ABSTRACT
Talented persons and medical equipment are both important for the development of the hospital. Improved management of medical equipment maintenance can make the equipment effective and lower maintenance cost, in which regular maintenance, enhanced management of equipment files are involved in.
