HD camera for medical endoscope

What are the ways to maintain the HD camera for medical endoscope? Regular monthly maintenance can ensure the normal operation of the video monitor. According to the instructions of each part of the monitoring system, check the technical parameters and eliminate hidden troubles. Especially in spring and summer, it is recommended to open it several times a week to avoid the insulation performance of electronic components being reduced due to moisture. When using the HD camera for medical endoscope, avoid running it for a long time, and avoid frequent startup and shutdown. Because this will damage the LCD lamp and shorten the life of the monitor.

Do you know the terminology of HD camera for medical endoscope?

HD camera for medical endoscope Interlaced and progressive are two types of scanning. To reduce jitter, the TV format uses interlaced scanning. In interlace mode, one scan line (one area) is generated every other line in one scan, and the remaining scan lines (two areas) are generated between scan lines generated in one pass by scan two. A complete image consists of these two parts, so flicker can be reduced. In progressive scan, a complete scan is performed sequentially from the top to the bottom of the screen.

The NTSC system defines a frame as 525 TV scan lines, 30 frames per second. The PAL/SECAM system defines a frame as 625 TV scan lines, 25 frames per second. HD camera for medical endoscope has multiple standards for high definition signals.

An LCD device without electron gun structure capable of displaying all pixels on a TFT screen simultaneously (progressive scan). I/P conversion can convert interlaced signals to progressive signals. In NTSC, the IRE unit refers to the 10:4 ratio of the video signal voltage level to the sync signal voltage level. The video signal is 0 to 100, and the sync signal is 0 to 40; in the PAL/SECAM system, the video signal voltage level and the sync signal voltage level are expressed in a ratio of 7:3, in millivolts.

HD camera for medical endoscope aperture control, a circuit that can apply edge correction or edge enhancement to the video signal. The resulting edge enhancement signal (“preshoot” for rising edges and “overshoot” for falling edges) is added to the original video signal for edge enhancement. Too much enhancement can result in blurry images. Enhancement also reduces image resolution.

HD camera for medical endoscope should pay attention to frequent dust removal to clean the dust on the surface of the display device. Regularly clean the dust and check the color and brightness of the monitor. Be careful not to place the monitor near heat sources or direct sunlight to avoid accelerated aging of the monitor and internal components. Monitors are particularly prone to attracting dust, therefore, they should be placed in a clean and well-ventilated environment. Do not place the monitor in a sealed cabinet, and pay attention to heat dissipation when monitoring. When using, the anti-tip cover or shielding cloth should be fully opened to facilitate heat dissipation.

HD camera for medical endoscope should not work while sick. If it is found that the monitor image is flickering, the brightness becomes brighter and a white retrace line appears, the smell of ozone is produced in the machine, or there is an internal fire, or there is abnormal sound, etc., you should stop using it immediately and repair it in time. The monitor is easily disturbed by magnetic fields and cannot be used together with other electrical appliances. What are the size requirements for HD camera for medical endoscope?

For the requirements of the screen size of the HD camera for medical endoscope, the selection principle is generally: a monitor that is only used to monitor one picture (including the alternate display of pictures), and the screen size can be smaller (for example, 14" monitor For monitors used to display multiple pictures at the same time (such as 16 pictures), the screen size should be larger. The screen size of the monitor should be based on the distance between the monitor and the monitor screen. 4-6 times the relationship of the angle line to be selected.

The HD camera for medical endoscope used to display black and white surveillance camera images should generally use black and white monitors; the monitors used for color surveillance cameras should use color monitors, so that the surveillance cameras correspond to the monitors. It is recommended to choose a monitor with a metal casing. Such a monitor has better shielding performance (especially after its casing is grounded) and is not easy to suffer from the interference of space electromagnetic fields.

The number of monitors is determined by the number of surveillance cameras. Generally, the 4, 1 method is adopted (if there are 16 camera points, 4 monitors should be selected). The special monitor for video recording can be set separately. According to the resolution index of the surveillance camera used, a monitor with a higher resolution should be selected, generally 100 TV lines higher.

What are the maintenance methods for HD camera for medical endoscope? Suggestions for using HD camera for medical endoscope: ensure stable power supply, so as not to damage components due to excessive current or voltage; pay attention to the temperature of the working environment not too high to prevent oxidation and aging; do not put Work in a humid and dusty environment; prevent static electricity and magnetic field interference.
