Abstract
The utility model provides a safety thoracocentesis needle which comprises a paracentetic needle, wherein the paracentetic needle is connected with a flow guide tube and provided with length scales; and side holes are formed at the end of the paracentetic needle. The safety thoracocentesis needle has the advantages that structure is simple, operation is convenient and practicability is high; the thoracocentesis needle provided by the utility model is safe and reliable, and can control the puncturing depth by observing the length of the scales on the paracentetic needle during operating, thus completely avoiding lung injury caused by excessive puncturing depth.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of safe thoracentesis needle.
Background technology
At present at the employed thoracentesis needle of hospital shown in accompanying drawing 1, comprise syringe needle and the drainage tube that is connected with syringe needle.In use, need the breakthrough sense of operator's subjective feeling punctures pleura, whether stop inserting needle with decision.This operation relies on individual's sensation and experience fully, and medical safety has been caused potential hidden danger.As a kind of improved method, can before operation, carry out the B ultrasonic location, to confirm paracentesis depth; But, do not have the length scale on traditional thoracentesis needle, still need operator to determine paracentesis depth by rule of thumb during operation; So, still can not avoid the dark problem that punctured fully, can cause stabbing lungs deeply and puncture; Cause pneumothorax, even cause patient death.
The utility model content
The purpose of this utility model is that traditional thoracentesis needle can not guarantee safe weak point, and a kind of safe thoracentesis needle that can safety operation is provided.
The purpose of this utility model reaches through following technical measures:
A kind of safe thoracentesis needle comprises puncture needle, and said puncture needle is connected with drainage tube, it is characterized in that: said puncture needle is provided with the length scale.
As a kind of improvement, the end of said puncture needle is provided with side opening.
When operation,, just can control the degree of depth of puncture, so can avoid paracentesis depth to cross the lung injury of taking an advanced study through observing the scale length on the puncture needle.And side opening can reduce or fiber, the deposition of back in the hydrothorax of avoiding puncturing stopped up pin hole, causes the problem of operator's repeated localised puncture.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) simple in structure, easy to operate, practical;
(2) safe and reliable, avoided paracentesis depth to cross the lung injury of taking an advanced study fully.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described further.
Description of drawings
Accompanying drawing 2 is structural representations of a kind of safe thoracentesis needle embodiment of this utility model.
The specific embodiment
Embodiment: shown in accompanying drawing 2, a kind of safe thoracentesis needle comprises puncture needle 3, and puncture needle 3 is connected with drainage tube 4, and puncture needle 3 is provided with length scale 2.
In the present embodiment, the end of puncture needle 3 is provided with side opening 1.
When operation,, just can control the degree of depth of puncture, so can avoid paracentesis depth to cross the lung injury of taking an advanced study through observing scale 2 length on the puncture needle 3.And side opening 1 can reduce or avoid fiber, deposition in the hydrothorax to stop up the puncture needle pin hole, causes the have to problem of repeated puncture of operator.
Claims (2)
1. a safe thoracentesis needle comprises puncture needle (3), and said puncture needle (3) is connected with drainage tube (4), it is characterized in that: said puncture needle (3) is provided with length scale (2).
2. a kind of safe thoracentesis needle according to claim 1 is characterized in that: the end of said puncture needle (3) is provided with side opening (1).
