Problems solved by technology
However, there is a problem here, that is, the negative pressure ball is soft, and its shape is irregular in the negative pressure state. Therefore, it cannot correspond to the scale line on the negative pressure ball, so it is impossible to accurately know the inside of the negative pressure ball. For the specific fluid volume, some patients need to constantly know the fluid volume. If you wait until the negative pressure ball fully recovers to record, it will undoubtedly reduce the work efficiency and is not conducive to the patient's condition control

The invention discloses a negative pressure drainage mechanism with the blood volume convenient to observe. The negative pressure drainage mechanism with the blood volume convenient to observe comprises a flask, scale lines, a negative pressure ball and a barrier mechanism. The flask is conical, and is made of a transparent hard material, when pressure in the flask decreases, the flask does not deform, thus the volume of hydrops in the flask is determined, and the upper end of the flask is connected with a liquid inlet pipe. The scale lines are arranged at the circumference of the flask, and through the scale lines, the volume of the hydrops in the flask can be known. The negative pressure ball is located on the upper side of the flask, the negative pressure ball is connected with the flask through a negative pressure pipe, a one-way air outlet valve is arranged on the negative pressure pipe, the one-way air outlet valve is located outside the flask, and when the negative pressure ballis squeezed, air in the negative pressure ball can be discharged through the one-way air outlet valve. The barrier mechanism is installed at an inner end of the negative pressure pipe, when the negative pressure ball pumps air, air in the flask can be pumped, and meanwhile, the hydrops in the flask is prevented from entering the negative pressure pipe.
Description
technical field [0001] The invention relates to the field of negative pressure drainage, in particular to a negative pressure drainage mechanism for convenient observation of blood volume. Background technique [0002] When bleeding or effusion occurs inside the body, it needs to be drained and excreted from the body. This requires the use of a negative pressure drainage device. The commonly used negative pressure drainage device uses a negative pressure ball, and the other end is connected to the fluid in the body. Press the ball, the gas is discharged from the one-way outlet valve, and in the process of recovering the deformation of the negative pressure ball, negative pressure is generated to draw out the fluid in the body. However, there is a problem here, that is, the negative pressure ball is soft, and its shape is irregular in the negative pressure state. Therefore, it cannot correspond to the scale line on the negative pressure ball, so it is impossible to accurately...
