Abstract

The invention relates to an anterior chamber puncture device which comprises a container unit, a puncture unit, a one-way unit, a plugging unit, a sealing unit, a pressure control unit and an indicating unit, the pressure control unit gradually reduces the pressure of the container unit, and aqueous humor enters the container unit and is in contact with and mixed with the indicating unit. The device has the advantages that the pressure control unit controls the pressure of the container unit in real time, the pressure of the container unit is larger than intraocular pressure at the moment when the puncture unit punctures the eyeball, and sudden drop of the intraocular pressure is avoided; the pressure control unit slowly reduces the pressure of the container unit to enable the pressure of the container unit to be close to and smaller than intraocular pressure, the one-way unit is opened, aqueous humor enters the container unit, and the steps are continuously repeated to enable the intraocular pressure to be slowly reduced; the pressure control unit reflects intraocular pressure in real time, the puncture device can be pulled out in time to end operation when the intraocular pressure reaches an ideal value, and repeated operation caused by still high intraocular pressure or complications caused by too low intraocular pressure are avoided. The color of the indicating unit can be changed after the indicating unit contacts with aqueous humor, so that an operator can observe the aqueous humor conveniently.

Description

technical field [0001] The invention relates to the technical field of eye treatment instruments, in particular to an anterior chamber puncture device. Background technique [0002] For patients with acute-closed angle glaucoma or neovascular glaucoma, whose intraocular pressure generally exceeds 50mmHg, anterior chamber puncture is required to drain the aqueous humor and reduce intraocular pressure. [0003] In clinical practice, physicians generally use a 1ml syringe for anterior chamber puncture. The moment the syringe penetrates into the eyeball, the intraocular pressure drops suddenly, which easily causes a series of complications such as hemorrhage and choroidal detachment. Clinically, there is a lack of anterior chamber puncture device that can make the intraocular pressure drop smoothly. At the same time, because the intraocular pressure cannot be monitored in real time, it is impossible to judge whether an appropriate volume of aqueous humor has been released duri...
