Description

Disposable puncture antral irrigator

Technical field

This utility model relates to the surgery of nasal cavity apparatus, and specifically a kind of disposable puncture antral irrigator is applicable to the treatment of chronic purulent rhinoantritis.

Background technology

Treat the chronic purulent rhinoantritis clinically, method commonly used is to the flushing of puncturing of maxillary sinus chamber, during flushing, earlier puncture needle is thrust the hole intracavity, the reuse syringe extracts the medicinal liquid in the medicinal liquid vessel, and the injector syringe nipple is inserted in the Paracentesis needle holder, promotes piston, make medicine liquid washing hole chamber, this flushing will be pulled up syringe repeatedly, and drawing liquid carries out repeatedly repeatedly, after reaching certain number of times, pus could be gone out from natural opening, reaches therapeutic purposes, this repeatedly drawing liquid, process of washing repeatedly, operation is wasted time and energy, and patient is painful big.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of operation simple in structure, easy to use, easy, disposable puncture, need not pull up the disposable puncture antral irrigator that syringe can wash continuously.

For solving above technical problem, the technical scheme that this utility model adopted is: this disposable puncture antral irrigator, constitute by syringe, piston, piston handle, puncture needle, piston bush is contained in the syringe, the needle stand of puncture needle is connected with syringe by turning to three-way valve automatically, turns to the side pipe of three-way valve to be communicated with the medicinal liquid bottle by connecting sebific duct automatically.This utility model is also implemented by following measure: this disposable puncture antral irrigator turn to three-way valve automatically, by valve body, side pipe, the feed liquor non-return valve, the fluid non-return valve, syringe nipple connecting hole, the needle stand connection tube constitutes, the feed liquor non-return valve is located in the side pipe, the fluid non-return valve is located in the needle stand connection tube, when piston outwards spurs, the spring compression of side pipe feed liquor non-return valve, the side pipe through hole is opened, and stifled tighter of the fluid non-return valve in the needle stand connection tube, at this moment, medicinal liquid sucks in the syringe in the medicinal liquid bottle, when piston promoted, medicinal liquid was compressed, and side pipe feed liquor non-return valve is then tightlyer stifled, and the spring of the fluid non-return valve in the needle stand connection tube is compressed, the fluid-through port of needle stand is opened, and medicinal liquid sprays in puncture needle, and this process can back and forth be carried out, do not need in the puncture needle needle stand, to pull up syringe, till flushing liquor is gone out from the nature mouth.When using this utility model, at first puncture needle is thrust and wear after the chamber puts in place, will turn to the needle stand connection tube of three-way valve to insert in the puncture needle needle stand more automatically and be connected firmly, can push away, piston handle washes.

The beneficial effects of the utility model are to compare with the flushing utensil of present application, and overall process simple in structure, easy to operate, as to use flexibly, can disposablely finish flushing has alleviated patient's misery, has improved surgical effect.
