Intraocular double-cavity injector with adjustable injection flow

Abstract

The invention provides an intraocular double-cavity injector with adjustable injection flow. The intraocular double-cavity injector comprises an injector tube body and a needle head seat, wherein thehead of the injector tube body is provided with a joint; the needle head seat is provided with a needle head; the needle head seat is detachably connected with the joint; two mutually independent injection cavities with the same volume are arranged in the injector tube body; the heads of the two injection cavities are respectively provided with liquid passages; the two liquid passages are converged at the joint in a Y shape; the liquid passages are provided with flow regulating devices; the tail part of the injector tube body is provided with an inflating piston; and the inflating piston is connected with a wave cutting machine. The intraocular double-cavity injector with the adjustable injection flow provided by the invention has the advantages that the design structure is simple and compact, the cost is lower, the disinfection is easy, the repeated use can be realized, the cost is reduced, the intraocular double-cavity injector is applicable to smaller ophthalmic surgery space, and the use is convenient; and the intraocular double-cavity injector with the adjustable injection flow can be used for simultaneously injecting two kinds of liquid medicine with different injection amounts and different proportions according to the requirements of ophthalmic patients, and the intraocular double-cavity injector is worthy of being applied and popularized in ophthalmic surgery.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical equipment, in particular to an intraocular double-chamber syringe with adjustable injection flow. Background technique [0002] At present, most of the syringes used at home and abroad are single-chamber syringes, which can only be applied to the injection of one liquid drug. However, in ophthalmic surgery, two liquid drugs need to be injected into the eyeball at the same time and mixed to form a drug. The drug works inside the eyeball to treat ophthalmic diseases, which cannot be done with existing single-chamber syringes. [0003] In the prior art, a three-way tube is commonly used clinically to complete the treatment of injecting two drugs at the same time, but because the operation space of ophthalmic surgery is small, the operation is inconvenient, and it is inconvenient for medical staff to control the injection pressure of the syringe. The three-way tube is used in ophthalmic sur...
