Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of for testing the long-range tonometer pressure measurement probe of intraocular pressure.
Background technology
Visual disorder, tumor, cardiovascular disease are the three major types illness that affects people's life quality that World Health Organization (WHO) proposes.The monitoring of daily blood pressure is extremely important to hyperpietic, same, and the control of daily intraocular pressure monitoring to blinding oculopathy is especially extremely important to glaucoma patient.Ocular hypertensive early stage control and intervention, can effectively avoid affecting adversely treatment opportunity, avoids irreversible blinding visual function damage, and the monitoring of these too busy to get away intraocular pressures.In China, there is the glaucoma patients that exceedes 15,000,000, and a considerable amount of potential patient, people's Vision Health exists huge threat.On the sphygomanometer market of domestic, be seen everywhere, but domestic tonometer is difficult to find trace.No matter existing tonometer is that Corneal Contact formula is also non-Corneal Contact formula, and eyelid contact, is mostly clinical ophthalmology Special medical equipment, all need professional medical personnel to operate use, and price is high, and general patient is difficult to purchase and use; Also have very the more important, existing exactly clinical tonometer all cannot be realized long-range intraocular pressure monitoring in operatorless 24 hours, and this monitoring is all extremely important with monitoring to the diagnosis of glaucoma patients and ocular hypertension.The household type electronic ophthalmotonometer that market demand is safe, easy-to-use, inexpensive and long-range tonometer, this utility model is researched and developed for such market demand just, is a kind of eyelid contact pressure measurement probe.
Chinese utility model patent application number 201310444618.2 and utility application numbers 201320589061.7 discloses a kind of mount type long-range tonometer that can be used for intraocular pressure monitoring in 24 hours.As the important composition parts of long-range tonometer, the Main Function of pressure measurement probe is the collection of intraocular pressure information.
In prior art, external Diaton tonometer is also a kind of eyelid contact tonometer, and the operation principle of its pressure measurement probe is: with the weight of fixing through eyelid striking eyeball vertical with sclera, according to eyeball bounce-back force measurement is realized to tonometry.The contact of form of a stroke or a combination of strokes tonometer front end has certain weight, when it touches eyelid in freely falling body mode, has the instantaneous elasticity reaction of eyeball pressurized, and this reaction is relevant to intraocular pressure.This reaction is recorded by electronic sensor, forms intraocular pressure data.(referring to < < intraocular pressure and glaucoma > >, week and political affairs, Shen Zhengwei chief editor, Hubei science tech publishing house.) Diaton pressure measurement probe is to carry out perception intraocular pressure information by electronic pressure transmitter, but the operation principle of Diaton pressure measurement probe is to rely on the gravity of freely falling body to obtain bounce-back reaction, need measured to adopt clinostatism, need operator's handgrip to hold tonometer simultaneously and maintain a vertical whereabouts angle, therefore necessary manual operation, cannot realize automatic operation arbitrarily angled, 24 hours random times, also therefore this tonometer cannot become long-range tonometer.Need a kind of pressure measurement probe that can be applied to Worn type tonometer of utility model for this reason, can meet conventional tonometry, can meet again the needs of intraocular pressure monitoring in 24 hours.
