Disclosed is a device for intrauterine shunting of fluid accumulation in organs. The barb at the proximal end of the disclosed shunt helps anchor the shunt in place, easing its placement and decreasing its dislodgement in-vivo, while the pigtail loop at the distal end maintains the shunt in place within an organ of a fetus. The stiffer shunt prevents occlusion from kinking and external pressure. Both of these properties may have a significant impact on shunt surgery and outcomes.

The present invention discloses a thoracic surgery nursing operation teaching model, which relates to the technical field of medical models, including a trunk model, a mounting plate, a puncture rubber plug, a fluid storage bin, a pipe interface, a hose, a syringe, a sealing cover, a sliding plug, a rubber bag, a puncture assembly, and a liquid pushing assembly arranged on the syringe. In the present invention, the liquid pushing assembly drives the sliding plug to slide in the syringe, thereby squeezing the liquid in the syringe to the fluid storage bin, so that the drainage fluid can enter the external drainage tube, and the closed drainage operation of the chest cavity is simulated. When the sliding plug moves to a fixed position, the puncture assembly will penetrate into the rubber bag, so that the marking liquid in the rubber bag flows into the syringe, so that the color of the liquid in the syringe turns red, and then the drainage operation under active bleeding is simulated. In addition, since the drainage fluid with a lighter color in the early stage can be simulated, and the drainage fluid in the late active bleeding can be simulated, the ability of novice medical personnel to deal with emergency situations can be greatly improved.

This invention relates to the field of medical device technology, specifically providing a pleural drainage device with monitoring function. This device, through the coordinated design of a first buoyancy component, a second buoyancy component, and a laser beam warning component, can accurately monitor the amount of fluid accumulated in the drainage cavity.
