Embodiment Construction

[0007] The following will refer to the attached figure 1 and 2 The shown schematic diagram of device design further illustrates the technical solution of the present invention.

[0008] The geometric dimensions of the device strictly refer to the geometric dimensions of the real human eye, and all dimensions are scaled up by 5 times. Except for the iris and the anti-leakage rubber pad, the manufacturing materials of the device are rigid materials, such as plexiglass transparent materials and stainless steel materials. The above requirements ensure the similarity principles of fluid mechanics such as geometric similarity and physical similarity of fluid flow in the device.

[0009] The cornea 1 and the aqueous humor efflux groove 2 can be integrated or connected together, and they are made of plexiglass. Its transparency is good, which can make it have the best light transmittance, which ensures that the optical path has the best clarity in the particle imaging velocimetry e...

Abstract

Provided is an anterior segment aqueous fluid circulating flow simulation device. The organization of the simulation device comprises a cornea (1), a sclera (6), a crystalline lens (12), a vitreous chamber (14), an iris (11) and the like. A functional mechanism comprises a aqueous fluid circulating flow control system, a crystalline lens moving control system, a pupil retardation simulation system and an intraocular temperature adjusting system which work in a cooperative mode, so that normal and abnormal aqueous fluid circulating flow simulation is guaranteed. An auxiliary device comprises an aqueous fluid discharging groove (2), an aqueous fluid flow-in groove (5), a control panel (9), a crystalline lens inner cavity (13), pipelines (3, 4, 23 and 24), a water-leakage-preventing rubber mat (17), an external temperature control system and the like.

Description

Technical field: [0001] The present invention relates to an anterior segment aqueous humor circulation simulation device, which can intuitively and effectively demonstrate that the intraocular aqueous humor is generated in the posterior chamber, enters the anterior chamber around the pupil edge, and finally flows out through trabecular meshwork and other tissues at the anterior chamber angle. flow process. Background technique: [0002] Aqueous humor is a transparent liquid secreted by the ciliary process epithelial cells of the ciliary body. It flows through the posterior chamber-pupil-anterior chamber angle, is discharged by trabecular meshwork, Schlemm's duct and other tissues and then enters the blood. Aqueous humor flows slowly in the eye, and its production and discharge is a reciprocating flow process. This flow process is directly related to the pressure inside the eyeball (intraocular pressure), the nutrient supply and metabolism of intraocular tissues. The effect...
