Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a waterproof and dustproof exposure lamp installation structure for a medical display screen. Background Art

[0002] With the advancement of medical technology, the operating environments of various medical devices are becoming increasingly complex, especially in operating rooms or field emergency situations. Medical display screens and other related equipment are therefore required to possess higher levels of protection. For example, patent CN214795773U discloses a medical display screen for telemedicine, which aims to address the poor dust and moisture resistance of existing medical display screens. Exposure lamps are typically used in conjunction with medical display screens. Exposure lamps used in medical environments must not only meet certain IP protection levels but also maintain good performance in conditions such as disinfectants and high-temperature, high-pressure steam. However, existing medical exposure lamps primarily focus on light source selection and illumination intensity control, with less consideration given to the protective performance of the device itself. Furthermore, their installation and use differ little from auxiliary lamps used on conventional computer screens, making them susceptible to intrusion by moisture, dust, and other pollutants, leading to short circuits or other electrical failures.

[0003] Patent CN217928163U discloses an LCD display with lighting. The rear end of the LCD screen has a bracket mounted on the inside of which an LED light panel is fixed for auxiliary illumination. Patent CN211289710U discloses an auxiliary light source for a display screen. The lamp body includes a housing and a light panel mounted within the housing, with a light outlet provided on the housing. Both of these devices lack a tight seal on the lamp body, making it susceptible to moisture, dust, and other intrusions, and therefore fail to meet the requirements for medical display screens.
