titleOfInvention Automatic control device for intracameral puncture drainage intraocular pressure
abstract The invention relates to an automatic control device for liquid discharging and intraocular pressure of anterior chamber puncture, which comprises a puncture needle, a needle cylinder, a pressure control valve and a spring, wherein the puncture needle is positioned at the head end of the needle cylinder, a piston and a piston rod are arranged in the needle cylinder, the pressure control valve and the spring are arranged between the piston and the puncture needle, the pressure control valve is positioned at one side close to the puncture needle, and the spring is positioned at one side close to the piston. And a pressure adjusting screw is arranged on the other side of the spring and used for accurately adjusting the spring force. The upper end and the lower end of the pressure control valve are respectively connected with the valve seat, so that the position of the pressure control valve can be better fixed. The puncture needle is also connected with a limiting head, so that the damage of the intraocular tissue caused by the fact that the needle head enters the anterior chamber too deeply can be avoided. In addition, the puncture needle is close to spacing head one side still is equipped with intraocular pressure monitoring head and cylinder upper and lower both sides and is equipped with display screen and receiver respectively, includes power and data processing chip in the receiver. Its advantages are: can realize controlling the aqueous humor flow rate, the automatic control of intraocular pressure puncture drainage, and can also realize real-time monitoring intraocular pressure.
