Pericardial effusion extraction device for emergency department

Abstract

The invention relates to the technical field of medical instruments, in particular to a pericardial effusion extraction device for the emergency department. The pericardial effusion extraction device comprises a base, a positioning mechanism and a suction mechanism; a shell is rotatably arranged on the upper end surface of the base, a shell inner cavity is limited in the shell, and a fixed inner plate is fixedly arranged on a center line of the bottom surface of the shell inner cavity in the front-back direction; the positioning mechanism comprises a rotating outer shaft rotationally arranged on the position, close to the upper portion, of the front end face of the base; and the suction mechanism comprises a first fixed cylinder fixedly connected to the upper end surface of the fixed inner plate. The problems that in the pericardial effusion extraction process, a puncture needle is not fixed, stability is poor, the replacing time of an extraction tube is long in the effusion extraction process, and consequently, the life safety of a patient is affected are solved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a pericardial effusion extraction device for emergency department. Background technique [0002] Pericardial effusion is a relatively common clinical manifestation and one of the important signs of pericardial disease. Pericardial effusion can be seen in exudative pericarditis and other non-inflammatory pericardial lesions, and can usually be confirmed by physical examination and X-ray examination. When pericardial effusion lasts for more than several months, it constitutes chronic pericardial effusion; when treating pericardial effusion, it is necessary to insert a puncture needle into the pericardial effusion to extract it. Since the front of the human heart is the lung, in the When performing pericardial drainage, it is possible to accidentally pierce the lung and form a pneumothorax. Therefore, when performing pericardial effusion puncture, attention should be paid...
