Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic postoperative auxiliary instruments, and in particular to a head position detection and reminder device used for post-ophthalmic fundus repair surgery. Background Art

[0002] Fundus repair surgery in ophthalmology mainly involves surgery for rhegmatogenous retinal detachment and macular hole. In vitrectomy for rhegmatogenous retinal detachment, after the vitreous traction is released and the hole is closed by freezing or laser, fillers such as silicone oil, inert gas, sterilized air, etc. are needed to press the hole. The hole is located at a relatively high position to achieve the best pressing effect, which is conducive to improving the success rate of the operation; similarly, after the macular hole surgery releases the traction of the vitreous and the internal limiting membrane, fillers are needed to press the macular hole to promote the closure of the hole. Therefore, patients need to take a prone position or a low head position after surgery, keep their face down, basically parallel to the ground, and reduce head movement. Since sterile air, inert gas, silicone oil and other substances need to be filled in the eye during the operation, and the density of such fillers is low, taking a prone position can make it float upward, play a role in pressing the retina and the hole, and prevent the filler from entering the anterior chamber, reducing the chance of complications. It usually takes 1-3 weeks to maintain, and some may need to be maintained for 1-2 months. However, patients may easily suffer from muscle soreness if they lie down with their heads down for a long time, and they cannot effectively and quickly sense whether their heads are still basically parallel to the ground. Therefore, a postoperative fundus detection reminder device is needed to help patients manage their postoperative body position. Summary of the invention

[0003] In view of the fact that the above background technology mentions that at this stage after fundus repair surgery, patients need to keep their heads down, but there is a lack of equipment to detect and remind patients of their head position. Therefore, a technical solution for a head position detection and reminder device after ophthalmic fundus repair surgery is provided.

[0039] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0040] After the patient has completed the fundus repair surgery, the patient, under the guidance of the doctor, keeps the head parallel to the ground or in a forward tilt angle according to actual needs, and sets the patient's head deviation angle threshold through the control panel 17. When the patient's head does not maintain a horizontal posture or a required angle, the angle sensor 16 will sense the change in angle and emit a sound and light alarm 15 that is audible and visible to the patient to remind him until the angle sensor 16 senses that the angle returns to the threshold range.
