The quality control analyzer of medical endoscope lighting system realizes the precise quality control of the light guide beam and cold light source of medical endoscope system accessories. The system integrates a spectral test system, an imaging analysis system, an optical radiation energy test system and a standard light source, etc., and can quickly realize the qualified judgment of the quality of the light guide beam and cold light source in 40 seconds based on the intelligent analysis algorithm on the device side. The PC-side medical endoscope life cycle quality control management system records and analyzes the periodic quality control test data, calculates the expected service life of the lighting system, and gives early warning to the system with serious quality conditions and failure risks; It has the function of medical economics analysis, analyzes the value of quality control management behavior of high-value medical devices, and provides data support for medical institutions to reduce costs and increase efficiency.
Quality failures and risk hazards
The medical endoscope-illumination system is mainly composed of two parts: light guide and cold light source. In clinical use, the light guide beam is repeatedly subjected to mechanical stress such as bending, pulling, plugging and unplugging, and it is very easy to break the internal optical fiber; Frequent fouling and use lead to obvious degradation of optical performance; Cold light sources are at risk of failure due to their long use. In the process of quality control management, there is a lack of efficient, convenient and clinically applicable testing equipment, which leads to the difficulty of current quality control management, high device failure rate, and great risks and hidden dangers.
1. The optical fiber bundle of the light guide beam is broken
2. The optical performance of the light guide is reduced due to long-term use
3. The optical performance of the cold light source is reduced due to long-term use
4. The optical performance is reduced after the light guide is repaired
5. The optical performance of the cold light source is reduced after maintenance
Test parameters
1. Light guide - spectral transmittance/transmittance/effective light guide ratio
2. Light guide-fiber density
3. Light guide beam-chromatic aberration
4. Cold light source-color rendering index
5. Cold light source - color temperature
6. Cold light source - luminous flux
7. Quality evaluation of light guide beam and cold light source
The quality control test system of medical endoscope lighting device is divided into equipment-side software, data analysis software and PC-side medical endoscope life cycle quality control management system. After the device is turned on, the incident and exit ends of the light guide beam are inserted into the designated interface of the device, and the software on the device side automatically analyzes the quality of the light guide beam and gives a qualified judgment. After the light guide is tested, the light guide is inserted into the cold light source to be tested, and the system automatically tests the relevant data of the light source. The test data is automatically transmitted to the PC software in the networked state, and the quality control management system of the whole life cycle of medical endoscopes is comprehensively analyzed according to the quality control management data records, and the quality of multiple medical endoscope lighting systems belonging to medical institutions is comprehensively analyzed, risk reminders and maintenance suggestions are issued, and the refined management and operation management of "double high" medical devices are fully implemented to reduce costs and increase efficiency according to quarterly and annual medical economic analysis data.
