Long-range tonometer pressure probe

Abstract

The invention provides a pressure measuring probe of a long-distance tonometer, which comprises a cavity screw rod with a through hole in the center; a wheel-shaped screw sleeve is sleeved on the outside of the cavity screw rod; Sliding sleeve; a probe rod and a pressure sensor are placed in the sliding sleeve; a return spring is provided at the front end of the sliding sleeve; an electromagnet ejection mechanism is provided at the rear end of the sliding sleeve; the pressure sensor The sensed force will be converted into a corresponding electrical signal and sent out. The present invention uses electronic control to complete a series of actions required by the pressure measuring probe, such as ejecting the probe rod and collecting pressure signals, and provides the possibility for program control of the pressure measuring probe instead of manual operation, thereby realizing long-range intraocular pressure The function of the meter provides the possibility.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a long-distance tonometer pressure measuring probe for testing intraocular pressure. Background technique [0002] Visual impairment, tumors, and cardiovascular diseases are three types of diseases that affect people's quality of life proposed by the World Health Organization. Daily blood pressure monitoring is very important for hypertensive patients. Similarly, daily intraocular pressure monitoring is very important for the prevention and treatment of blinding eye diseases, especially for glaucoma patients. Early control and intervention of high intraocular pressure can effectively avoid delaying the timing of treatment and avoiding irreversible blinding visual function damage, and these are inseparable from the monitoring of intraocular pressure. There are more than 15 million glaucoma patients in our country, and a considerable number of potential patients, and there is a huge...

Problems solved by technology

) The Diaton manometry probe senses intraocular pressure information through an electronic pressure sensor, but the working principle of the Diaton manometry probe is to rely on the gravity of the free fall to obtain a rebound response, requiring the subject to be in a lying position and the operator to hold the eye Tonometer is used to maintain a vertical drop angle, so it must be operated manually, and automatic operation at any angle and at any time in 24 hours cannot be realized, so this tonometer cannot be a long-range tonometer
