Description

Pericardiocentesis liquid-drawing tool

Technical Field

The utility model relates to the technical field of medical tools, concretely relates to pericardium puncture drawing liquid instrument.

Background

The pericardiocentesis is a diagnosis and treatment technology for directly puncturing the pericardial cavity by a puncture needle. The pericardial puncture must be carried out under the aseptic technique, local application of procaine anesthesia, the puncture position must not be too deep to avoid puncturing atria, ventricles or coronary artery to cause a large amount of blood accumulation in the pericardial cavity, a patient with pericardial puncture can know the nature of the pericardial effusion by testing the liquid in the pericardial cavity and find out the cause of pericarditis according to the nature of the pericardial effusion, the pericardial puncture has certain danger, but if the pericardial puncture is carried out carefully according to the strict operating rules, the method is a relatively safe diagnosis and treatment method.

According to the clinical practice of the medical science at present, some medical personnel can't correctly judge the depth of puncture under the condition that the pericardial puncture technique is not skilled to easily, then directly carry out the operation of pericardial effusion extraction at the shallow position of puncture position, if so, very easily cause secondary injury to the patient. Therefore, we propose a pericardial puncture drawing tool to solve the above problems.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a pericardial puncture drainage tool to solve the problem of the prior art that the pericardial effusion is directly extracted from a shallow position of the punctured part due to the inexperience of some medical personnel's manipulation techniques.
