Abstract

The invention relates to a drainage guiding device for the department of cardiology. The problem that in the prior art, equipment with the quantitative liquid taking function and the periodic needle withdrawing function lacks is effectively solved. According to the technical scheme, the drainage guiding device comprises: a shell and a liquid extraction cavity, wherein the liquid extraction cavity is detachably connected to the upper end of the shell; a bearing ring, wherein a plurality of vacuum liquid taking pipes are detachably mounted on the bearing ring; an injection head, wherein one end of the injection head is communicated with the liquid extraction cavity, and the other end of the injection head can be inserted into the vacuum liquid extraction pipe; and a piston rod which is controlled by a control structure arranged in the shell, wherein the control structure is internally provided with the following control steps of a piston long process step, a piston short process step, a bearing ring stepping step and an injection head intermittent lifting step. The drainage guiding device is simple in structure and convenient to operate, can automatically extract a pericardial effusion sample, has the functions of periodic needle withdrawing and quantitative effusion extraction, reduces the difficulty of pericardial effusion extraction, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of cardiology equipment, in particular to a drainage guide device for the cardiology 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. When pericardial effusion lasts for more than several months, it will Constitute chronic pericardial effusion. [0003] In the early stage of treatment, pericardial effusion usually requires pericardial puncture to extract pericardial fluid for analysis. During the sampling process, it is usually necessary to draw pericardial effusion into different vacuum tubes in stages and retain it for detection and analysis. [0004] In the process of puncture and fluid collection, there are the following precautions: [0005] 1. The needle needs to be withdrawn regula...
