Problems solved by technology

When the existing punctum expander and irrigator are split structures, it is necessary to use the punctum expander to expand the lacrimal duct first, and then use the irrigator to inject the irrigating liquid. Prepare to judge the insertion depth of the needle of the irrigator and the needle of the dilator, which will increase the pain of the patient. At the same time, it is very easy to penetrate the lacrimal duct mucosa, causing complications such as bleeding and false tracts; If the pressure is too high during the flushing process, the needle will easily fall off, causing iatrogenic injury

Abstract

The invention discloses a disposable lacrimal passage flushing device. The disposable lacrimal passage flushing device comprises a lacrimal punctum enlargement unit and a lacrimal passage flushing unit. The lacrimal passage flushing unit comprises a syringe pre-filled with flushing liquid, a piston and a piston pushing mechanism. The lacrimal punctum enlargement unit comprises a sleeve type flushing needle and a needle core, the left portion of the sleeve type flushing needle extends to the left out of the syringe, and a sealing ring on the middle portion of the sleeve type flushing needle divides the sleeve type flushing needle into left and right cavities. The needle core is disposed in the left cavity in a penetrating mode, and the right end of the needle core extends into the right cavity. The right cavity is internally provided with a needle core pushing mechanism, and a lacrimal punctum enlarging head at the left end of the needle core extends out of the flushing needle. A liquidoutlet hole is formed in the side wall of the syringe, and a liquid inlet hole is formed in the sleeve type flushing needle in a corresponding mode. The liquid outlet and inlet holes are located on the left side of the sealing ring. The disposable lacrimal passage flushing device has the advantages that the structure is simple, the operation is convenient, lacrimal puncta can be enlarged and a lacrimal passage can be flushed, and the disposable lacrimal passage flushing device is especially suitable for patients with narrow lacrimal puncta; and iatrogenic injury can be completely avoided, complications such as bleeding and false passages are reduced, and the safety is high.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to a disposable lacrimal duct flushing device. Background technique [0002] Lacrimal duct irrigation is an operation technique of injecting irrigation liquid or other liquid medicine into the lacrimal duct to clear the blockage of different parts, and it is a routine method for diagnosis and treatment of lacrimal duct diseases. When the existing punctum expander and irrigator are split structures, it is necessary to use the punctum expander to expand the lacrimal duct first, and then use the irrigator to inject the irrigating liquid. Prepare to judge the insertion depth of the needle of the irrigator and the needle of the dilator, which will increase the pain of the patient. At the same time, it is very easy to penetrate the lacrimal duct mucosa, causing complications such as bleeding and false tracts; If the pressure is too high during the flushing process, the needle will easily fa...
