Abstract

The invention discloses a flushing needle for anterior chamber paracentesis. The flushing needle comprises a puncture needle head and a cylinder body. The flushing needle is characterized in that the puncture needle head is nested in a flat needle head with a smooth port, and a push rod is arranged on the outer surface of the cylinder body; a cavity is formed in the outer edge of the cylinder body, and a measuring valve body for measuring a pH value in the cylinder body and a pH adjusting valve body for adjusting the pH value in the cylinder body are arranged in the cavity; and the pH adjusting valve body is used for adjusting a pH value of liquid in the cylinder body according to feedback information of the measuring valve body. Firstly, the puncture needle head penetrates through the inner side of the limbus corneae of a patient to form a puncture opening, then, the push rod is used for enabling the flat needle head to slide and wrap the puncture needle head, and then, the flat needle head is used for flushing an anterior chamber; the pH value of the liquid in the cavity is obtained through the measuring valve body in the cavity, and the pH value of the liquid in the cavity is equal to that of the liquid in the anterior chamber; and the pH value in the cylinder body is adjusted by using the pH adjusting valve body, so that imbalance of the pH value of the anterior chamber caused by replacement of aqueous humor of the anterior chamber and the flushing liquid is avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a flushing needle for anterior chamber puncture. Background technique [0002] Anterior chamber puncture includes diagnostic anterior chamber acentesis, anterior chamber anterior chamber anterior chamber anterior chamber lavage, and anterior chamber puncture. Among them, in the anterior chamber flushing operation, it is necessary to first use the flushing needle to pass through the puncture port inside the limbus, and then inject flushing fluid into the flushing needle to flush the anterior chamber; for patients with acid-base chemical burns on the eye, if After flushing, the pH value in the anterior chamber cannot be balanced, and if it continues to be alkaline or acidic, it will further damage the deep eye tissue; therefore, it is important to maintain the pressure balance between the anterior chamber and the outside world during this process. In a balanced state, the circulatio...
