Technical Field
The utility model belongs to the technical field of medical instrument, mainly relate to a left heart drainage tube with pressure measurement and negative pressure stationary flow function.
Background
More cannulae are used in cardiovascular surgery, and the left cardiac drainage tube is one of these cannulae. Its effect mainly has following three points:
first, the left heart depressurizes. In the process of extracorporeal circulation, the left intracardiac pressure can be reduced through the left ventricular drainage tube, and the damage caused by expansion of the left ventricle is avoided.
Second, the surgical field is kept clear. During open-heart surgery, blood is constantly being returned to the left atrium through the pulmonary veins, which, if not properly constantly aspirated, may flood and obscure the surgical field. Left heart decompression allows the surgeon to perform the procedure unhindered in a relatively clear surgical field of view.
And thirdly, lung protection. If the blood returned from the left heart is not properly sucked, the pressure in the left heart increases, which increases the pressure of the blood vessels in the lung, and over time, edema of the lung tissue may occur, causing complications, such as lung perfusion.
In order to avoid damaging surrounding blood vessels and other tissues when the left cardiac drainage tube is used, the existing left cardiac drainage tube is made of a soft material, the left cardiac drainage tube is generally placed from the starting part of the right pulmonary vein, and the starting part of the right pulmonary vein is deeper due to the soft material of the left cardiac drainage tube, so that the visual field of an operator is poor, the left cardiac drainage tube is inconvenient to place, and potential operation risks are increased.
