Description

Double-cavity syringe needle

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a two-chamber syringe needle.

Background

At present, an injector is a necessary common instrument for collecting, diluting and configuring liquid medicines, reagents and the like in medical units and laboratories, the injector utilizes a needle to realize medicine injection for patients, and anesthesia and medicine injection are often required to be carried out on the patients during operation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defect that the prior single-cavity syringe needle is inconvenient to inject medicine for many times, and providing a double-cavity syringe needle.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a two-chamber syringe needle, is including pintle, needle handle and the needle point that connects gradually, connect the syringe needle and connect the syringe needle down respectively from top to bottom in the inside of pintle, the end of needle point still is provided with the pinhole.

Preferably, the upper and lower needles converge into a common needle passage inside the pintle.

Preferably, the upper and lower needles are funnel-shaped.

Preferably, the needle point is a 3mm round pure needle, and a needle hole is formed in the needle handle at the position 3mm away from the needle point.

Preferably, the pinhole is a plug with an inclined plane of 45 degrees.

Preferably, the four sides of the lower needle head of the pintle are provided with transverse grains.

A double-cavity syringe needle comprises a pintle, a needle handle and a needle point which are sequentially connected, and is characterized in that a half groove with the diameter of 2.5mm is formed in the tail end of the needle point.

The utility model has the advantages that:

1. the lateral side of the lower needle head of the pintle is provided with transverse grains, so that the common injector can be quickly butted.

2. The lower connector head and the upper connector head are converged into a channel of a needle tube in the same direction at the front edge, and a 1ml syringe can be connected with the upper connector head for anesthetic refilling, so that the anesthetic and the medicine introduced by the lower connector head can be conveniently mixed and injected.
