Description

Technical Field

[0001] This invention relates to the field of otolithiasis detection technology, and more particularly to an AR glasses for otolithiasis detection. Background Technology

[0002] Benign paroxysmal positional vertigo (BPPV), also known as otolithiasis, is the most common peripheral vestibular disorder characterized by recurrent positional vertigo or dizziness. This disease can be classified into idiopathic and secondary types based on its cause, and further subdivided according to the location of the affected semicircular canals: posterior semicircular canal type, lateral semicircular canal type, anterior semicircular canal type, and multi-semicircular canal type. It is most common in men and women over 40 years of age, with a male-to-female ratio of approximately 1:1.5 to 1:2.0, and the incidence increases with age. Treatment methods include: 1. Posterior semicircular canal repositioning method (1) Epley maneuver: The patient sits on the bed. Turn the head 45 degrees to the affected side. Quickly place the patient in a supine position with the head tilted back 30 degrees. While keeping the head at a 45-degree angle to the affected side, turn the head 90 degrees to the unaffected side. Turn the patient's body and head together to the unaffected side to form a lateral decubitus position, with the head still tilted at a 45-degree angle. The patient sits up, keeping the head tilted at a 45-degree angle, until symptoms are relieved.

[0003] (2) Sémons repositioning method: The patient sits on the edge of the bed with their head tilted 45 degrees to the unaffected side. Quickly place the patient in a lateral decubitus position on the affected side, keeping the head tilted at 45 degrees. Wait for the nystagmus to stop. Quickly place the patient in a lateral decubitus position on the unaffected side, turning the head to the unaffected side. The patient sits up.

[0004] 2. Horizontal semicircular canal BPPV repositioning (1) Gufoni repositioning maneuver: The patient lies on their side with their head turned to the side with stronger nystagmus. Quickly turn the head to the side with weaker nystagmus and hold that position for a period of time. The patient then turns to the other side and repeats step 2.

[0005] (2) Barbecue roll: The patient starts from a side-lying position. Roll continuously 180 degrees until returning to the starting position, pausing for a period of time after each roll. The patient rolls 180 degrees again and returns to the starting position.

[0006] 3. Anterior semicircular canal BPPV repositioning Brandt-Daroff Exercise: The patient sits on the bed. Slowly tilt the head back until dizziness or nystagmus occurs. Maintain this position until the dizziness or nystagmus stops. Slowly return to a sitting position, then slowly lie down face down. Maintain this position again until the dizziness or nystagmus stops. Slowly sit up and rest.

[0007] Patient needs: Patients desire rapid and effective treatment to reduce the inconvenience caused by dizziness and lower medical costs. Doctors' needs: Doctors require tools to improve the accuracy and efficiency of treatment and reduce errors during the process. Hospitals' needs: Hospitals hope to improve service quality and attract more patients by introducing new technologies, while also considering the cost and maintenance of equipment. Therefore, a product needs to be designed to meet the needs of patients, doctors, and hospitals. Summary of the Invention
