Electric folding and unfolding mechanism and electric adjusting mechanism for dry-eye inspection device

Abstract

The invention provides an electric folding and unfolding mechanism and an electric adjusting mechanism for a dry-eye inspection device. According to the invention, a slit lamp optical body, a slit lamp bent arm, the electric folding and unfolding mechanism, the electric adjusting mechanism and the dry-eye inspection device are included. A fixed part of the electric folding and unfolding mechanismis mounted on a slit lamp body; the output part of a first driving device drives a rotating part of the electric folding and unfolding mechanism to rotate; a fixed part of the electric adjusting mechanism is mounted on the rotating part of the electric folding and unfolding mechanism, and the dry-eye inspection device is connected to a sliding part of the electric adjusting mechanism; and the output part of a second driving device drives the sliding part of the electric adjusting mechanism to move in an axis direction. According to the invention, through the arranged second driving device andthe arranged adjusting mechanism and under the control of a computer, the dry-eye inspection device automatically move to respective working positions according to different dry-eye examination items(tear film rupture examination, meibomian gland examination, lipid layer examination, tear river height examination and the like), so the accuracy of inspection results is ensured.

Description

technical field [0001] The invention relates to the field of devices in the field of medical equipment, in particular to an electric retractable mechanism and an electric adjustment mechanism of a dry eye inspection device. Background technique [0002] Eyes are the most important organ of human senses, and about 80% of the knowledge in the brain is acquired through eyes. Eyes are used for reading and recognizing characters, looking at pictures and paintings, seeing people, and enjoying beautiful scenery. [0003] Dry eye is the most common ocular surface disease with a high incidence. Its incidence rate in China is 20-36%. In recent years, its development trend has shown an obvious growth trend due to the increase in the frequency and time of eye use. The study of this disease has practical significance for human health. [0004] Various examinations for dry eye, including: tear river height measurement, tear film breakup time measurement, meibomian gland analysis, lipid ...

AI Technical Summary

Problems solved by technology

[0014] a. Directly rotate from the working position B and C to the non-working position D, and the dry eye device will collide with the slit lamp, causing damage to the equipment;

[0015] b. Turning directly from the non-working position D to the working position A may easily cause the device to collide with the patient's face and cause damage;

[0016] c. Position errors caused by incorrect operations affect the accuracy of inspection results;

[0017] d. To ensure that the above problems do not occur, doctors need to operate professionally, the process is more complicated, and the work intensity and difficulty are increased;

[0018] e. Every time you use it, you have to touch the device with your hands, which is easy to cause secondary infection between different operators, and it is not easy to protect the operator
