The puncture auxiliary device for cardiovascular examination comprises a supporting frame, an adjustment sliding block, a connector and a guiding block; the supporting frame is sleeved with the adjustment sliding block, and a plurality of suctioncups are arranged at the bottom of the supporting frame; the adjustment sliding block is provided with the connector and fastened to the supporting frame through a second fastening bolt, the connector is provided with the guiding block, the guiding block is arranged on the connector through a connecting rotation shaft, the connecting rotation shaft penetrates through the connector, one end of theconnecting rotation shaft is connected with the guiding block, the other end of the connecting rotation shaft is connected with an adjusting handle, and the adjusting handle is provided with a firstangle pointer. The puncture auxiliary device for cardiovascular examination has the advantages that the device is convenient to use, positioning is accurate during lung puncture for a patient, the puncture success rate is high, convenience is provided for needle insertion, the operation is simple and convenient, the time and labor are saved, and the work difficulty of medical staff is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a puncture auxiliary device for cardiovascular examination. Background technique [0002] At present, the cardiovascular system is composed of the heart and blood vessels, which in turn include arteries, veins and capillaries. The heart is a hollow muscular organ located in the middle of the chest cavity, divided into two chambers by a septum, and each chamber is divided into two parts: the upper atrium and the lower ventricle. The atria collect blood from the heart, and the ventricles eject blood from the heart. There are valves at the inlet and outlet of the ventricles that allow blood to flow in one direction. Under different physiological conditions of the human body, the metabolic levels of various organs and tissues are different, and the requirements for blood flow are also different. Cardiovascular activity can change cardiac output and peripheral ...

Problems solved by technology

In pericardiocentesis, the puncture needle needs to be left in the pericardial cavity for a long time to facilitate the extraction of pericardial fluid. During this process, the doctor needs to hold the needle for a long time to keep it fixed. The patient causes extremely dangerous situations such as myocardium being stabbed. The existing pericardiocentesis fixation frame has a large body, unreliable fixation effect, high production cost, cumbersome disassembly, and extremely inconvenient use and operation, causing great harm to medical staff. It is troublesome, and it also poses a great safety hazard to the patient's surgical safety.
