Description

Lacrimal passage flushing device with pre-packaged physiological saline

Technical Field

The utility model relates to the field of medical instruments, in particular to a lacrimal passage flushing device pre-packaged with physiological saline.

Background

Lacrimal passage irrigation is a common operation in ophthalmology, and is commonly used for understanding inflammation and obstruction of lacrimal passage; judging whether there is contraindication of operation, such as lacrimal passage flushing before operation for cataract patients; treating lacrimal duct obstruction or chronic dacryocystitis.

The conventional lacrimal passage flushing step is that a certain amount of normal saline is firstly extracted by a syringe, then a sharp-end needle head is pulled out and connected with a flat-end needle head, and then the needle head is arranged in the lacrimal passage for repeated flushing.

There are problems at present:

1. more spare materials, complicated steps and long time consumption. Iodine, cotton swabs and physiological saline are additionally prepared for each lacrimal passage flushing, and the mouth of the physiological saline is required to be disinfected; the needle needs to be replaced after the liquid is pumped.

2. The rigid connection of the syringe to the needle affects the flexibility of operation. Because the dissection walking of the lacrimal passage has a certain angle, the needle inserting scheduling needs to be adjusted in the operation process, but because the needle head of the needle cylinder is rigidly connected, the needle cylinder often needs to be moved greatly in the operation under the action of the lever principle, and the flexibility is influenced.

3. The syringe is directly operated in front of eyes of a patient, so that the uneasy mood of the patient is increased.

4. The flexibility of the device is not good enough, and the difficulty in learning and operating young medical workers is increased.

4. If misoperation occurs, the risk of injury of lacrimal passages and peripheral soft tissues is increased. If the needle cylinder slips off the hand in the operation process, the needle cylinder is filled with liquid, is heavy, and the needle head is pressed downwards to be driven to pry upwards under the seesaw principle, so that tear mucosa injury is easily caused, bleeding or infection is caused, and eyeballs are even injured.

Therefore, there is a need for a pre-packaged saline lacrimal irrigation device that overcomes the above-mentioned deficiencies.
