Embodiment Construction
[0023] Now in conjunction with the accompanying drawings, the structure and use of the present invention will be further described. Such as Figure 1-Figure 3 As shown, the electromagnetic intraocular pressure measuring probe 4 is composed of a measuring head 401 , a main body 402 , a magnetic fluid 403 and a cover 404 under the action of a gradient magnetic field. When measuring intraocular pressure, the measuring head is in contact with the cornea of the eyeball; at the same time, a gradient magnetic field is applied to the magnetic fluid part through the front coil 5 and the rear coil 6 to adjust the size of the gradient magnetic field; when the intraocular pressure of the measuring head and the eyeball reaches equilibrium, the gradient The numerical value of the magnetic field forms a corresponding relationship with the intraocular pressure value, and then displays the magnitude of the intraocular pressure on the display through the relationship between the magnetic fiel...

The invention relates to an electromagnetic intraocular pressure measurement probe and measurer. The measurement probe of the intraocular pressure measurement probe comprises a measurement head, a main body and a cover, wherein magnetic fluid is arranged in the main body; the measurement probe is characterized in that a conical columnar head is arranged at one end of the measurement probe main body; the measurement head is arranged at an end part orifices of the columnar head; the end part orifices is connected with a liquid cavity in the other end of the main body through a channel in the columnar head; the magnetic fluid is arranged in the liquid cavity; the liquid cavity is cylindrical-shaped and the cover is arranged on a back part cavity opening of the liquid cavity; the intraocular pressure measurer is characterized in that a front coil extends out of the columnar head end of the measurement probe main body; the front coil and a back coil are positioned on the two sides of the cylindrical-shaped liquid cavity of the main body respectively; the front coil, the back coil, a display switch button and left and right eye selection buttons are connected with a circuit board through a circuit; the circuit board is provided with an electromagnetic control module, a current control module and a processor; and the front coil and the back coil control the strength of a gradient magnetic field through changes of current strength to measure stress changes of the magnetic fluid in the probe so as to determine an intraocular pressure numerical value.
Description
technical field [0001] The invention relates to an intraocular pressure measuring instrument and a measuring probe, and is an electromagnetic intraocular pressure measuring probe and a measuring instrument. Background technique [0002] The detection method of intraocular pressure refers to the detection of intraocular pressure through medical equipment and medical methods to control the patient's condition (such as glaucoma) and prevent possible eye diseases in patients with diabetes and hypertension. The existing relatively common IOP detection methods include: finger pressure measurement, tonometer examination and non-contact tonometer examination. Finger pressure measurement can only roughly estimate the intraocular pressure and needs clinical experience as the basis; The main purpose of contact tonometer examination is to assist in the diagnosis of glaucoma and to observe the effect of treatment. The tonometer test refers to a contact tonometer, not a contact tonometer...
