[0031] By arranging the handle 3 and the drainage joint 4 on the same side, the main body liquid collection device can be operated with one hand;

[0032] A guide tube 5 connected to the drainage joint 4 is fixedly installed inside the handle 3, a pump barrel 6 is installed at the axial position of the cover body 1, and the inner wall of the pump barrel 6 is provided with a power chamber and a filtrate chamber 7 isolated from each other from top to bottom, the surface of the filtrate chamber 7 is connected to the guide tube 5, and a power component driven by a negative pressure generating component is installed inside the power chamber, the bottom end of the filtrate chamber 7 is rotatably connected to a filtrate barrel 8 driven by the power component, spiral sealing leaves 9 are fixedly installed on the circumferential side of the filtrate barrel 8, and a group of blast blades 10 distributed in a circular array are installed at the bottom of the filtrate barrel 8.

[0041] The device is mainly suitable for the collection of body fluids. When working, the drainage joint 4 is connected to the external body fluid collection pipeline, and then the body fluid collection operation is performed. By setting the handle 3 and the drainage joint 4 on the same side, the body fluid collection device can be operated with one hand. During the drainage operation, the operator presses the pressing bag 12 back and forth, and then the inside of the negative pressure generating chamber 11 can reciprocate negative pressure suction and positive pressure exhaust. When the negative pressure generating chamber 11 is positively pressurized, the pump shaft 16 and the inner shaft 18 rotate, and the filtrate cylinder 8 is set in a rotating state, so that the filtrate cylinder 8 can centrifugally filter out the body fluid.
