CN2337964Y - Multi-purpose puncturing needle - Google Patents

Abstract

The utility model relates to a puncture instrument for medical treatment, transferring the liquid state medium of the human body, or extracting liquid state medium from human body. The utility model is composed of the connection of a needle stand and a needle tube, wherein a pillar surface of the needle tube is provided with a plurality of small bores. The multi-purpose puncturing needle has the advantages of reasonable structure and favorable service performance. No matter how much liquid is in the puncture chamber, whether the position is correct, the needle point is higher or lower than the liquid surface, as long as the needle tube is provided with a position in the medium, the liquid medium in the puncture chamber can be better extracted. The utility model can prevent the blocking of the content in the chamber, and can satisfy the requirement of diagnosis and treatment.

Description

Use puncture needle more

This utility model relates to medical treatment, for shifting the human body liquid medium or in human body, taking out a kind of puncture utensil of liquid medium.

In medical procedures such as surgery, gynecological, internal medicine, the puncture needle that uses is connected and composed by needle stand and needle tubing two parts at present, long 8 centimeters of needle tubing, about 0.8 millimeter of diameter, and there is needle point at front end pin hole place.The deficiencies in the prior art part, mainly be unreasonable structure, be limited that serviceability is not good enough: when puncturing diagnosis or treatment, often can not exactly the liquid medium in the puncture chamber be pumped out, because what of puncture intracavity liquid medium, the height of liquid level is difficult to know concrete condition before the puncture, especially puncture in the chamber medium more after a little while, after puncture needle entered, needle point was higher or lower than liquid level, all aspirated the liquid less than the puncture intracavity; In addition, the tolerant also easy unique needle point hole of stopping up of puncture intracavity, influence diagnosis and treatment.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of rational in infrastructure, puncture needle products of using that serviceability is good are provided more.

Can take following technical scheme to realize purpose.Use puncture needle more, still connect and compose, but also be provided with some apertures on the cylinder of needle tubing by needle stand and needle tubing.

Under the prerequisite that satisfies the said structure requirement, as for many overall structure form with puncture needle, the length of each several part, thickness, the size of aperture on the needle tubing cylinder, what, arrangement mode etc., all can be according to using needs, take the circumstances into consideration to set, they can both reach the purpose and the result of use of the technical program.

The relative prior art of the technical program has following advantage and effect:

Rational in infrastructure, serviceability is good: when puncturing diagnosis or treatment, no matter puncture intracavity liquid medium is many or less, whether the orientation correct, needle point is more or less than liquid level, as long as needle tubing has the position that is in the medium, can both preferably the liquid medium in the puncture chamber be pumped out; The puncture intracavity is tolerant to be difficult to stop up all holes, all has result of use preferably in all cases, satisfies the requirement of diagnosis and treatment.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is many a kind of structural representations with puncture needle;

Fig. 2 is that many with puncture needle other plant structural representation.

Shown in the drawings many with among the puncture needle embodiment, the needle tubing 2 that is connected with needle stand 1,8 centimeters of length, about 0.8 millimeter of diameter, there is needle point at front end pin hole place, 0.8 millimeter in the aperture 3 on the needle tubing cylinder, aperture.

In embodiment illustrated in fig. 1, how the aperture 3 with puncture needle is distributed on needle tubing 2 cylinders of needle stand more than 2.5 centimeters.It is suitable for first or puncture intracavity liquid medium is less, use when liquid level is more shallow.

In embodiment illustrated in fig. 2, how the aperture 3 with puncture needle is distributed on the whole cylinder of needle tubing 2.Use when dark in its chamber that is suitable for puncturing.

The serviceability of accompanying drawing illustrated embodiment, result of use are good.

Claims (3)

1, a kind of uses puncture needle more, connect and compose, it is characterized in that: also be provided with some apertures on the cylinder of needle tubing by needle stand and needle tubing.

2, as claimed in claim 1ly use puncture needle, it is characterized in that: aperture is distributed on the needle tubing cylinder of needle stand more than 2.5 centimeters more.

3, as claimed in claim 1ly use puncture needle, it is characterized in that: aperture is distributed on the whole cylinder of needle tubing more.
