Strabismus detection device

Abstract

The invention provides a strabismus detection device. The strabismus detection device comprises a human body fixing chair, a measuring rod and a nine-direction camera, wherein the human body fixing chair comprises a chair body; a first transverse rod is arranged on one side of an armrest of the chair body and located on the outer side of a cushion; one end of the first transverse rod in the lengthdirection is connected to the chair body, and the other end extends out of the outer side of the chair body and is rotationally provided with a vertical rod; a second transverse rod is mounted at oneend, away from the first transverse rod, of the vertical rod; a head fixing device is arranged at the end, away from the vertical rod, of the second transverse rod, and comprises a lower jaw fixing plate, two ear fixing plates and a head top fixing plate; the measuring rod is mounted on the head top fixing plate; and the nine-direction camera comprises a chassis which is connected with a nine-direction structure through a lifting structure. The device can fix the head of a patient, displacement of the patient in the detection process is avoided, meanwhile, the 33 cm distance needed by detection can be accurately obtained, a doctor can conveniently operate the device for shooting examination, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a strabismus detection device. Background technique [0002] Strabismus means that both eyes cannot fixate on the target at the same time. It is a common disease in ophthalmology. Accurate degree of strabismus is an important factor affecting the therapeutic effect. At present, the commonly used methods for measuring strabismus include: prism plus cover detection method, corneal light reflection method, etc. During the inspection process, the patient’s face is required to face straight ahead. When facing the patient’s face, both ears need to be exposed and equal. Only the eyeballs can be moved, and the head cannot be moved accordingly, otherwise the nine-direction map taken during the inspection process does not meet the requirements and will affect the test results. [0003] Furthermore, the current strabismus detection lacks a dedicated instrument to obtain the nine-posi...

During the inspection process, the patient’s face is required to face straight ahead. When facing the patient’s face, both ears need to be exposed and equal. Only the eyeballs can be moved, and the head cannot be moved accordingly, otherwise the nine-direction map taken during the inspection process does not meet the requirements and will affect the test results

[0003] Furthermore, the current strabismus detection lacks a dedicated instrument to obtain the nine-position map, which makes the entire detection process time-consuming and inaccurate. In addition, when obtaining the nine-position map, it needs to be acquired at a distance of 33cm from the human face. Currently , the distance is not obtained accurately, that is, the camera lens is easy to change during the shooting process when obtaining the nine-direction map, so that there is a certain error in the obtained image, which affects the accuracy of the detection, and in order to ensure the accuracy of the detection, then It can only be realized with the assistance of doctors and assistants, which makes the whole detection process more troublesome, labor-intensive, and time-consuming
