Embodiment 1

[0022] Embodiment one: if figure 1 , figure 2 As shown, a meibomian gland infrared imaging device, its device main body includes an infrared lighting device 1, a visible light lighting device 2, a focusing light device 11, a coated mirror 4, a focusing lens 5, an infrared camera 6, and a microscope observation device 7 .

[0023] The infrared illuminating device 1 includes two or more sets of infrared point light sources (infrared light beams), and each infrared light point light source (infrared light beams) is symmetrically distributed according to the main optical axis 10 of meibomian glands reflecting infrared light. In this embodiment, two beams of infrared light are used as the infrared illuminating device 1 to act as the main illuminating device. The infrared light emitted by the infrared illuminating device 1 is irradiated on the meibomian glands of the subject, and the reflected infrared light on the meibomian glands Reflected by the coated mirror 4, it enters the ...

Embodiment 2

[0033] Such as image 3 As shown, this embodiment is a portable solution of the present invention. The difference between this embodiment and Embodiment 1 is that this embodiment is small and portable, and the microscope observation device 7 is omitted, and front and rear, left and right, up and down and other mechanical movement devices. And the desktop device of embodiment one has microscope observation device 7 and mechanical movement devices such as front and rear, left and right, up and down.

[0034] In addition, this embodiment considers from the perspective of compactness and portability, and the data exchange between the main part of the device and the computer is carried out in a wireless manner. However, the data exchange between the desktop device and the computer in Embodiment 1 is carried out in a cable mode (wireless mode can also be used).

Embodiment 3

[0036] The difference between this embodiment and Embodiment 1 is that the microscope observation device 7 is a single-lens observation device, which is located at the rear end of the coated mirror 4 , and visible light enters the microscope observation device 7 through the coated mirror 4 .

[0037] The coated reflector 4 is a reflector with low reflectivity to visible light. The coated mirror 4 is a 45-degree mirror, which turns 90 degrees to reflect the incident infrared light, and then enters the infrared camera 6 through the focusing lens 5; the incident visible light does not change the optical path transmission, and then enters the microscope observation device 7.

Abstract

The invention discloses a meibomian gland infrared imaging device. A device body comprises an infrared illumination device (1), a visible light illumination device (2), a film-coated mirror (4), a focusing light device (11), an infrared camera (6) and a microscopic observation device (7). Infrared light emitted by the infrared illumination device (1) irradiates on the meibomian gland of a detected person, the infrared light on the meibomian gland is reflected by the film-coated mirror (4) to enter the infrared camera (6) to be shot. A focusing lens (5) is arranged between the infrared camera (6) and the film-coated mirror (4). The focusing light device (11) is used for proofreading and allowing space between the focusing lens (5) and the meibomian gland of the detected person to be fixed and constant. By the aid of the meibomian gland infrared imaging device, the meibomian gland can be displayed clearly and directly, a doctor can observe, measure and judge condition and structure of the meibomian gland, and the meibomian gland infrared imaging device can be applied to diagnosis, treatment and prevention for a patient with a meibomian gland dysfunction.

Description

technical field [0001] The invention relates to a meibomian gland infrared imaging device. Background technique [0002] Meibomian gland dysfunction is an ocular surface disease caused by abnormalities in the quality and quantity of meibomian gland secretions caused by inflammation and other reasons. It is very common in clinical practice, especially in the middle-aged and elderly people, but it is often overlooked. One of the reasons for being ignored is that there are special difficulties in the observation and recording of the meibomian glands in clinical ophthalmology. Under ordinary visible light lighting conditions, the meibomian glands distributed in strips are invisible to the human eye, which brings a lot of trouble to inspection and diagnosis. [0003] However, if infrared lighting is used, infrared cameras are used, and computers and monitors are used, the strip-distributed meibomian glands can be clearly and intuitively displayed for observation, measurement and...
