A pericardial effusion positioning and deriving mechanism

Abstract

The invention provides a pericardial effusion positioning and exporting mechanism, which includes a fixed seat, an inner column is fixedly connected to the inside of the outer cylinder, a base is fixedly connected to the left end of the inner column, and a slider 1 and a slider 2 are movably sleeved on the outer side of the inner column. , the inside of the outer cylinder is movably connected with evenly distributed positioning blocks, the left side of the positioning block is movably plugged with a telescopic seat, the left side of the telescopic seat is fixedly connected with a suction cup, and the inside of the telescopic seat is movably plugged with a platen. The pull plate drives the slider 2 and the slider 1 to move to the leftmost one after another. The slider 2 drives the block 2 to extend outward through the connecting rod, drives the tooth plate to move outward through the gear 2 and the rack section on the base, and drives the gear plate to move outward through the adjustment plate. Squeeze the telescopic seat and move it to the left, so that the suction cup is adsorbed on the patient's skin. Similarly, the suction cup on block 1 is tightly adsorbed on the patient's skin. Therefore, the base is fixed on the patient's body through the suction cup, thereby strengthening the patient's body. Positioning stability of the puncture needle.

Description

technical field [0001] The invention relates to the technical field of pericardial effusion derivation, in particular to a pericardial effusion positioning and derivation mechanism. Background technique [0002] Pericardial effusion is a relatively common clinical manifestation, especially after echocardiography has become a routine examination method for cardiovascular diseases, the detection rate of pericardial effusion in patients has increased significantly, and pericardial effusion can be clinically asymptomatic , but cardiac tamponade occurs when fluid builds up causing pressure in the pericardial space to increase and compress the heart. [0003] In the treatment of pericardial effusion, the commonly used method is pericardial drainage. The catheter is sent to the pericardial cavity through a puncture needle, and the pericardial fluid is drained out through the catheter. Since the front of the human heart is the lungs, pericardial drainage is performed. Occasionally,...

[0002] Pericardial effusion is a relatively common clinical manifestation, especially after echocardiography has become a routine examination method for cardiovascular diseases, the detection rate of pericardial effusion in patients has increased significantly, and pericardial effusion can be clinically asymptomatic , but cardiac tamponade occurs when fluid builds up causing pressure in the pericardial space to increase and compress the heart

[0003] In the treatment of pericardial effusion, the commonly used method is pericardial drainage. The catheter is sent to the pericardial cavity through a puncture needle, and the pericardial fluid is drained out through the catheter. Since the front of the human heart is the lungs, pericardial drainage is performed. Occasionally, it may accidentally pierce the lung and form a pneumothorax. Therefore, when performing pericardial effusion puncture, attention should be paid to ensuring the positioning stability of the puncture needle to ensure the smooth discharge of pericardial effusion. However, the traditional pericardial effusion The structure of the liquid positioning and exporting device is simple, and it is mostly held by the medical staff for stability, and cannot effectively fix the puncture needle, which requires high work requirements for the medical staff and is inconvenient to use
