Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] As shown in the figure, the present invention includes a syringe 1, an injection head 9, an injection needle 5, a needle fixing part 3, a hard hemp catheter 6, and a catheter fixing part 7, and the injection needle 5 is connected to the described injection needle through the needle fixing part 3. On the injection head 9, the hard hemp catheter 6 is set outside the injection needle 5, and the hard hemp catheter 6 is fixed by the catheter fixing part 7, the injection needle 5 is a hard tube, and the hard hemp catheter 6 is fixed by the catheter fixing part 7. Hard hemp conduit 6 is flexible pipe. Because the hose is outside and the hard tube is inside, it can avoid the situation where the needle touches the lacrimal duct during lacrimal duct irrigation.

[0015] In this embodiment, the left end of the injection needle 5 is fixedly connected to the...

Abstract

The invention discloses a lacrimal passage washing device. The lacrimal passage washing device comprises an injector, an injection head, an injection needle head, a needle head fixing part, a hard hemp catheter, and a catheter fixing part. The injection needle head is connected to the injection head through the needle head fixing part. The hard hemp catheter is sheathed outside the injection needle head, and the hard hemp catheter is fixed through the catheter fixing part. The injection needle head is a hard pipe. The hard hemp catheter is a hose. The lacrimal passage washing device is capableof effectively preventing the needle head from injuring a lacrimal gland by mistake in a washing process of the lacrimal passage, and effectively avoiding the cross infection generated in a repeatedusing process of the used hard hemp catheter in the washing process.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a lacrimal duct flushing device. Background technique [0002] The flushing device used in common lacrimal duct irrigation is single in structure and unreasonable in design, and usually uses stainless steel needles for syringes, but the disadvantage of this method is that the lacrimal duct is a relatively fragile organ. Stainless steel needles are easy to accidentally injure the lacrimal duct during the operation, especially for children, because of psychological tension and easy crying, the needle often injures the lacrimal duct during the lacrimal duct flushing process. Another disadvantage is that in the lacrimal duct irrigation, if the injection needle is not replaced in time, but the same injection needle is cleaned and used, it is easy to cause cross-infection to the patient. Contents of the invention [0003] The object of the present invention is to provide a lacrima...
