Head fixing part for fundus photography examination

Abstract

The invention discloses a head fixing part for fundus photography examination. The head fixing part comprises a camera base and a handrail, wherein a camera mounting position is arranged at the top of the camera base; a control switch is arranged at one corner of the top of the camera base; a front adjusting hand wheel is arranged on one side wall of the camera base; a head fixing frame is arranged on the other side wall of the camera base; and a rear adjusting hand wheel is arranged on one side wall of the head fixing frame. The head fixing part has the beneficial effects that a sliding rod is arranged between the head fixing frame and the camera base, so that the head fixing frame can be flexibly separated and is suitable for people with different head shapes; and limiting holes and the handrail are arranged on the two sides of the head fixing frame, so that an examiner can hold the head fixing part with two hands and relax the stiff body, and the examination accuracy of the device is improved.

Description

technical field [0001] The invention relates to the technical field of fundus cameras, in particular to a head fixture for fundus photographic inspection. Background technique [0002] The fundus mainly includes the vitreous body, retina, optic nerve, macular area and other structures. When the fundus is lesioned, the corresponding structure and its color will change accordingly. Fundus photography is to record the degree and scope of the lesion at the time of the fundus lesion, such as the retina The area of ​​degeneration and hemorrhage can be observed by fundus photography, whether it has expanded or shrunk. The color change of optic atrophy can be observed by fundus photography, whether it is aggravated or lightened. The range of macular degeneration and hemorrhage can be observed by fundus photography. The scope is to expand or shrink, the absorption of blood loss, and whether there is fresh bleeding. [0003] In the common fundus camera, the head fixing part is mostly...

Problems solved by technology

[0003] In the common fundus camera, the head fixing part is mostly integrated with the camera. It can only adjust the position of the head up and down, but not the front and rear positions. For different head shapes, the focus of the eyes will be affected, which is not conducive to the device's photographing. At the same time, the posture of the person being inspected is mostly stretching his head and leaning forward, and his hands cannot be supported, resulting in a tense state of the head, which increases the inaccuracy of the inspection
