The application discloses a glaucoma drainage device and belongs to the technical field of medical devices. The glaucoma drainage device comprises a drainage sheet, the inside of which is a cavity structure, the drainage sheet is divided into a left cavity and a right cavity through a first partition plate, the upper surface of the left cavity is provided with a drainage hole, and the first partition plate is provided with a drainage opening; a drainage assembly is in communication with the inside of the drainage sheet through a connecting hole provided on the drainage sheet; and a fixing mechanism is arranged on the drainage sheet and used for fixing the drainage sheet and the drainage assembly. The glaucoma drainage device can fix the drainage assembly and the drainage sheet of the device through a mechanical fixing structure, avoids the problems of the suture fixation of the drainage device in the prior art, simplifies the operation process, shortens the operation time, reduces the complications caused by the suture foreign matter, and improves the fixing reliability and safety.

This invention discloses a method for producing low-temperature resistant plastic granules for pipes, comprising the following steps: Step 1, cleaning the waste material, and then adding the raw material to a high-speed mixer to obtain a premix; Step 2, adding the premix to a twin-screw extruder and heating it to a molten state for plasticization. This invention relates to the field of plastic granule preparation technology. In this method for producing low-temperature resistant plastic granules for pipes, wastewater is discharged into a circulation tank, driving a turbulence impeller to rotate. While the wastewater is filtered through a grading filter plate, a scraper removes dirt from the surface of the grading filter plate, preventing clogging. Furthermore, the drainage area of ​​the drainage channel can be increased by adjusting the water flow, increasing the water pressure and the impact force on the turbulence impeller, thus increasing the thrust on the scraper and improving the cleaning effect.

This invention discloses a gallbladder drainage stent for ERCP surgery, comprising an insertion tube, several sets of connecting ribs fixedly connected to the outside of the insertion tube, a communicating groove opened on the outside of the connecting ribs, several sets of rotating plates rotatably connected inside the communicating groove, a rotating block rotatably connected to the inner side of the outer end of the rotating plate, a support plate fixedly connected to the outside of the rotating block in the same group, sliding rods slidably connected to the inside of both sides of the support plate, contact plates fixedly connected to the outside of the sliding rods, several sets of connecting tubes fixedly connected between the contact plates, a through tube fixedly connected between the middle of the connecting tube and the inside of the insertion tube, and a fluid inlet opened on the outside of the connecting tube. The entire stent can be deployed and anchored with only one action, making the operation simple and quick, significantly shortening the operation time, reducing surgical risks and patient suffering.

The utility model discloses a high weatherability's windowsill drainage board structure, including drainage unit, and the drainage bayonet groove of recessing inwards is equipped with to the window frame and is located outdoor one side, and the drainage bayonet groove is located below the water passage hole of window frame, and its inner top wall is equipped with L type buckle, and one end of drainage unit is through L type buckle and is connected with the drainage bayonet groove, and its other end extends to the outside of outer wall veneer, and its bottom end sets along the top end surface of outer wall veneer to reach the purpose of drainage. The utility model discloses a high weatherability's windowsill drainage board structure, and this drainage board structure adopts physical structure and is connected with window frame to solve the leakage caused by the high dependence on sealant in the prior art, prevent after sealant aging, and the drainage area that can be used is increased by the slope surface of the top of this drainage board structure to the water diversion, thereby making drainage more smooth and improving drainage capacity, and this drainage board structure does not need to use screw and other fasteners to fix, thereby reducing the difficulty of installation.
