Technical Field

[0001] The utility model relates to the field of intraocular pressure measurement, in particular to an intraocular pressure measurement and fixation device. Background Art

[0002] Intraocular pressure plays a very important role in maintaining the structure of the eye, waterproof circulation and vision. It is basically equivalent to our body's blood pressure. If the intraocular pressure is high, it will compress the optic nerve and cause damage to the optic nerve. This kind of damage is generally difficult to recover. An intraocular pressure measuring device is needed to measure the patient's intraocular pressure.

[0003] However, when using a practical intraocular pressure measuring device to measure a patient, since the intraocular pressure measuring device will blow gas into the patient's eyeball, the patient may move his head when stimulated, resulting in inaccurate intraocular pressure measurement results. Therefore, the patient's head needs to be fixed to prevent the patient's head from moving. Utility Model Content
