Abstract

The invention discloses a head position measuring device capable of collecting nystagmus data. The head position measuring device comprises a carrier, a head position angle measuring unit, a data transmission unit and an eye movement measuring unit, and is characterized in that the carrier is a glasses type frame, and a nose pad is fixedly arranged at the bottom of the front end of the carrier; the eye movement measuring unit comprises two sub-measuring units arranged on the two sides of the carrier respectively; each sub-measuring unit comprises a sliding rod, an adjusting screw and an infrared camera; an empty groove is formed in one end of each sliding rod and arranged on a fixing screw on the side portion of the carrier in a sleeving mode; a locking nut capable of clamping the sliding rods together with the carrier is in threaded connection with the corresponding fixing screw; one end of the adjusting screw is in threaded connection with a locking nut and an adjusting nut which can cling to two sides of the other end of each sliding rod; each infrared camera is fixedly arranged at the other end of the corresponding adjusting screw; the head angle measuring unit comprises an IMU sensor fixedly arranged on the carrier; and the data transmission unit comprises a Wi-Fi module and a battery which are electrically connected. According to the device, nystagmus measurement can be carried out while head position measurement is performed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a head position measuring device capable of collecting nystagmus data. Background technique [0002] Nystagmus is an involuntary, rhythmic, back-and-forth swinging eye movement, which can cause visual impairment, binocular visual function impairment, diplopia, compensatory head position and other hazards. Studies have shown that compensatory head position angle and nystagmus intensity are of great significance in the fields of ophthalmology and ergonomics, and are often used clinically as the basis for the diagnosis of congenital nystagmus. [0003] At present, there are compensatory head position measurement devices developed using a coordinate ruler in clinical practice in China today, which can simultaneously measure the deflection angles of the head position in the three axes of X, Y, and Z, but the accuracy is poor and the degree of automation is low. Subsequently...
