Abstract

The invention belongs to the technical field of medical instruments, and in particular relates to a disposable intraocular injection syringe. The disposable intraocular injection syringe comprises a casing, a syringe needle and a plunger, and a plurality of distance markers can be evenly disposed on the syringe needle for determining the length of the syringe needle insertion. The color of the distance marker is red or orange. The injection syringe solves the problem that the existing intraocular injection does not have any reference for the doctor to refer to, and the doctor is difficult to judge the insertion depth of the syringe needle, which is unfavorable for a surgery. By increasing the depth of the syringe needle insertion by adding a plurality of the distance markers, the depth ofthe syringe needle insertion can be effectively determined, the safety of the intraocular injection is enhanced, and the distance marker is the eye-catching color such as red or orange to help the doctor notice the distance marker more easily.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable intraocular injection syringe. Background technique [0002] As a medical device, a syringe needs to have extremely high precision requirements, especially when injecting intraocular medicine, the size of the syringe used is very small, and there is no reference mark for the doctor to refer to, so it is difficult to judge the needle insertion Depth is unfavorable for operation. Contents of the invention [0003] The present invention provides a disposable intraocular drug injection syringe for the above problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] The disposable intraocular injection syringe includes a casing, a needle and a plunger, and a plurality of distance marks are uniformly arranged on the needle for judging the insertion length of the needle. [0006] The colo...
