Abstract

The invention discloses a disposable simple puncture drainage needle. The disposable simple puncture drainage needle comprises a metal puncture needle, a drainage hose needle, a drainage tube, a three-way base, a drainage liquid container and a rubber plug, wherein the drainage hose needle is connected with the needle connector end of the three-way base, the rubber plug is arranged at the position of an end opening, opposite to the needle connector end, of the three-way base, one end of the drainage tube is connected with the third end opening of the three-way base, the other end of the drainage tube is connected with the drainage liquid container, and the needle head of the metal puncture needle penetrates through the rubber plug, the three-way base and the drainage hose needle in sequence. The drainage liquid container is a bag-shaped container. The length of the drainage hose needle is 8 cm, and maximum length of the portion, stretching out of the drainage hose needle, of the metal puncture needle is 6 cm. By the adoption of the structural form, the drainage hose needle replaces an existing metal needle to be used for guidingpleural effusion and seroperitoneum out, operation is safer and more reliable, and the viscus is prevented from being injured.

Description

Disposable plain type puncture drainage needle

Technical field

The present invention relates to a kind of armarium, specifically a kind of disposable plain type puncture drainage needle.

Background technology

When hydrothorax and seroperitoneum outwards being drawn, be all generally adopt metal needle, metal needle is easy in thoracic cavity and intraperitoneal damage internal organs, safe not.

Summary of the invention

In order to overcome above-mentioned deficiency, the object of the invention is to provide a kind of easy to use, disposable plain type puncture drainage needle that structure is simple, safe and reliable.

To achieve these goals, the technical solution used in the present invention is:

Disposable plain type puncture drainage needle, include puncture metal needle, conduction hose pin, drainage tube, threeway seat, drainage-fluid container and rubber stopper, described conduction hose pin is connected with the needle adapter end of threeway seat, rubber stopper is located at the port relative with needle adapter end of threeway seat, one end of drainage tube is connected with the 3rd of threeway seat the port, the other end is connected with drainage-fluid container, and the syringe needle of described puncture metal needle is successively through rubber stopper, threeway seat and conduction hose pin.

Described drainage-fluid container adopts bag-like container.

The length of described conduction hose pin is 8cm, and the greatest length that described puncture metal needle passes in conduction hose pin is 6cm.

Beneficial effect of the present invention: owing to adopting above-mentioned version, replacing existing metal needle by conduction hose pin derives hydrothorax and seroperitoneum, more safe and reliable during operation, avoids the damage to internal organs.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Fig. 1 is structural representation of the present invention.

In figure: 1, puncture metal needle; 2, conduction hose pin; 3, drainage tube; 4, threeway seat; 5, drainage-fluid container; 6, rubber stopper.
