Glaucoma aqueous humor drainage device

Abstract

The invention provides a glaucoma aqueous humor drainage device, relates to the technical field of medical apparatuses and instruments, and solves the problems that when a person accidentally touches a handle for liquid suction, the handle is easily adjusted greatly, and then eyes of a patient are easily injured due to violent suction force; the repeated use phenomenon cannot be effectively avoided, and the repeated use phenomenon cannot be avoided through structural improvement. A glaucoma aqueous humor drainage device comprises a liquid pumping structure. And a cleaning structure is installed on the liquid pumping structure, a suction pipe is further installed on the liquid pumping structure, and an auxiliary structure is further installed on the liquid pumping structure. Due to the fact that the head end of the cutter is of the sharp structure, the cutter makes contact with the threads on the threaded rod, and the cutter forms a damage structure of the threads on the threaded rod, the threads on the threaded rod can be damaged through the cutter when the threaded rod is rotated, and repeated use of the liquid pumping structure is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a glaucoma aqueous humor drainage device. Background technique [0002] Glaucoma is a very harmful common eye disease, ranking first among irreversible blinding eye diseases. For the treatment of glaucoma, eye drops, laser, or trabeculectomy can be used according to the severity; for refractory glaucoma that cannot be treated by the above conventional methods, the current treatment and drainage are more difficult. [0003] For example, the application number: CN201920443893.5 discloses a multifunctional glaucoma aqueous humor drainage device, which relates to the technical field of medical devices. The multifunctional glaucoma aqueous humor drainage device includes a syringe, and a drainage tube is provided on one side of the syringe. The drainage tube is connected to the syringe through a connector, and one end of the drainage tube relative to the connec...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a glaucoma aqueous humor drainage device to solve the existing problem that the safety performance of the existing device is low, and when a person unintentionally touches the handle for absorbing liquid, it is easy to cause the handle to be greatly deformed. Adjustment, and then easily cause the patient's eye injury because of violent suction; Furthermore, the existing device can not effectively avoid the phenomenon of repeated use, but can not avoid repeated use through structural improvement; finally, the existing device cannot be used in the The problem of automatic wiping of the pumping structure while pumping
