Abstract

The invention discloses a multipurpose anterior chamber puncture device with a pressure monitoring function. The multipurpose anterior chamber puncture device comprises an aqueous humor collecting assembly, a pressure measuring and displaying module and a pressure / flow stepless inching adjusting module which are sequentially connected from front to back. Wherein the aqueous humor collecting assembly is used for puncturing the cornea of an eyeball and collecting aqueous humor; the aqueous humor collecting assembly is provided with scales for reading the release amount of the aqueous humor; the pressure measurement and display module is used for measuring and displaying anterior chamber intraocular pressure in real time when the aqueous humor collection assembly collects aqueous humor and guiding the pressure relief control process; the pressure / flow stepless inching adjusting module is used for adjusting intraocular pressure and the flow velocity of the aqueous humor when the aqueous humor collecting assembly collects the aqueous humor. According to the multi-purpose anterior chamber puncture device with the pressure monitoring function, quantitative collection of aqueous humor can be achieved, intraocular pressure can be monitored in real time, and the intraocular pressure release speed and the aqueous humor outflow speed can be controlled.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical instruments, in particular to a multipurpose anterior chamber puncture device with a pressure monitoring function. Background technique [0002] Clinically, anterior chamber puncture is often required in order to reduce intraocular pressure, sample and analyze the aqueous humor of eye infection, or perform other anterior chamber drainage treatments / anterior chamber flushing. [0003] Intraocular pressure (IOP), also known as intraocular pressure, is the pressure of the contents of the eyeball on the inner wall of the eyeball. Intraocular pressure varies at different times of the day, but generally remains within a safe range. The intraocular pressure range of normal people is 11-21mmHg (1.47-2.79kPa), in order to maintain the normal shape of the eyeball and maintain a good refractive state at the interface of each refractive medium. The contents of the eyeball include aqueous humor (A...
