Abstract: Provided is a supergravity directional solidification melting furnace equipment, including a supergravity test chamber and, mounted in the supergravity test chamber, a high-temperature heating subsystem, a crucible, and an air-cooling system. The supergravity test chamber is mounted with a wiring electrode and a cooling air valve device. The high-temperature heating subsystem is fixed in the supergravity test chamber. The crucible and the air cooling system are provided in the high-temperature heating subsystem. The high-temperature heating subsystem includes upper, middle, and lower furnaces, a mullite insulating layer, upper and lower heating cavity outer bodies, upper and lower heating furnace pipes, and a crucible support base. A high-temperature heating cavity is divided into upper and lower parts, is provided therein with a spiral groove, and is fitted with a heating element. The crucible support base is provided therein with a vent pipe channel into which a cooling air is introduced.

Abstract: A complete flow diversion intestinal ostomy surgery kit, comprising an ostomy tube, the ostomy tube comprising a tube body; near the front end of the tube body is provided with a deformable balloon; a fine tube is provided within the tube wall of the tube body or inside the tube body; the front end of the fine tube penetrates the tube wall of the tube body and is in communication with the inner cavity of the balloon; when filled with fluid via a connector, the balloon and the intestinal wall form a sealed structure that blocks matters inside of the intestine; the complete flow diversion intestinal ostomy surgery kit further comprises a ring-shaped fixing plate; the exterior wall of the tube body is provided with a ring-shaped groove; the ostomy tube is fixedly connected to the abdominal wall of a patient via the ring-shaped fixing plate that matches the ring-shaped groove.
