Maintenance of gastrointestinal mirrors Gastrointestinal mirrors are a class of sophisticated and valuable optical and electronic instruments. They must strictly abide by the operating procedures during the process of use, and implement their maintenance and repair systems in a specific manner, strictly, check, fine, clean, rush, and save. .
Strict: a strict management system. Establish the operating procedures of the instrument, establish the use and maintenance registration file of the instrument, and implement the responsibility of the person; prohibit the use of the instrument by those who are not familiar with the performance of the instrument.
Check: Before the operation, it is necessary to carefully check all parts of the circuit and the components of the instrument, check whether the circuit and wire contact are good, whether the voltage meets the requirements, whether the performance of each component of the instrument is normal, and whether the endoscope has leakage. In use, it must be strictly used according to the instrument operating procedures; after use, turn off the power switches in turn, and finally cover the instrument dust cover.
Fine: that is meticulous. When installing, operating, and washing the endoscope, it must be lightly handled, lightly handled, lightly taken, and lightly operated. When cleaning the endoscope, it should be stable. Do not allow the endoscope to collide and excessively twist, so as not to damage the endoscope.
Net: It is clean. The endoscope and its accessories must be cleaned and disinfected in strict accordance with the requirements of the 2004 edition of the Ministry of Health.
Rush: flushing. On the basis of “netâ€, the endoscope and accessories should be flushed with as much air and water as possible to prevent air and water blockage. Thoroughly rinse the patient for complete gastric retention, poor bowel cleansing, gastrointestinal bleeding, tissue biopsy, and longer endoscopy. Also wash as much as possible for the general patient.
Save: Save. The endoscope should be stored after specification. After the use of the same day, the endoscope should be thoroughly cleaned, disinfected, dried, maintained (leakage, wiped with no alcohol on the head, wiped with alcohol on the lens, oiled on the button, etc.) and stored in a dedicated internal mirror cabinet (suspended) , safe), and regularly open UV disinfection.
Common endoscopic failure troubleshooting methods
First, the cause of air blockage or poor air supply
1 The tip end accidentally collides with the hard object to deform the nozzle, and the nozzle is clogged (inappropriate endoscope maintenance is the main cause of blockage);
2 After using the endoscope, it is not cleaned immediately, and the dirt is solidified in the nozzle, and the nozzle is clogged; 3 The endoscope is not completely washed with detergent before disinfection, so that the disinfectant causes the mucus and protein to solidify and block the nozzle;
4When the mirror is wiped, the direction is wrong, the cotton yarn is inserted into the nozzle, and the nozzle is clogged;
5 After the nozzle is clogged, picking the needle or removing the nozzle by itself may cause the nozzle to be damaged or cause the inner tube to be more easily blocked;
6 Others, such as gas pump poor gas production, poor connection between the endoscope connection and the host, poor connection of the water bottle.
Anti-blocking measures
1 When operating the endoscope, it should be light and stable to prevent the front end from colliding and damaging the nozzle;
2 When the endoscope is in use, it is necessary to give air in a timely manner, and appropriate water injection can prevent the liquid in the cavity from retrograde into the air supply and water supply pipeline;
3 After the endoscope is used, it should be cleaned immediately, and cleaned, disinfected and dried in strict accordance with the specifications;
4When wiping the mirror surface, follow the direction of the nozzle;
5 After the nozzle is clogged, the endoscope can be immersed in the warm water enzyme washing solution, and then the whole pipeline is pressurized and irrigated. Do not use the needle to pick it up or remove the nozzle by itself to avoid endoscope leakage;
6 Connect the parts of the endoscope correctly.
