The utility model discloses a gastrointestinal fluid drainage device, which relates to the technical field of medical instruments and is characterized by comprising a drainage tube and a spiral flow deflector fixedly mounted in the drainage tube, an anti-displacement mechanism is arranged on the outer side of the drainage tube, and an anti-suck-back mechanism is arranged at the fluid outlet end of the drainage tube. A gastrointestinal fluid collecting device is arranged at a fluid outlet of the suck-back preventing mechanism, the shifting preventing mechanism comprises an elastic assembly and an inflation assembly, the elastic assembly comprises a basic ring fixedly installed at the fluid inlet end of the drainage tube, and a film cylinder is fixedly installed at one end of the basic ring; the device has the technical effects that the problems that the drainage tube is easy to displace and the drainage liquid is blocked are effectively solved by utilizing the anti-displacement mechanism, the spiral flow deflector and the smooth polytetrafluoroethylene drainage tube as well as the anti-suck-back mechanism and the gastrointestinal fluid collecting device, meanwhile, the drainage efficiency and safety are improved, the continuity and stability of the drainage process are ensured, and the drainage effect is good. And a more reliable and effective auxiliary means is provided for treatment and rehabilitation of the patient.

This utility model discloses a polishing device for compressor parts, relating to the field of compressor parts processing technology. It includes a base, a mounting bracket fixed to the base in an inverted U-shape, a processing mechanism built into the mounting bracket, and a protective mechanism to prevent dust from scattering. The protective mechanism includes two sliding door plates slidably disposed on the front and rear sides of the mounting bracket, the two sliding door plates being staggered. The mounting bracket also has a power component for the two sliding door plates to slide in opposite directions. The power component includes a push-pull assembly on one side of the mounting bracket and a transmission assembly on the top of the mounting bracket. Through the protective mechanism, when the polishing machine is moving downwards to polish the parts, the two sliding door plates cooperate to effectively cover the openings on the front and rear sides of the mounting bracket, ensuring the internal sealing of the mounting bracket and preventing dust generated during polishing from scattering outwards, thus reducing dust pollution to the environment.
