Abstract: A biodegradable double-J stent and a method of manufacturing a biodegradable double-J stent are provided. The stent comprises a main tube, a first retaining tube, and a second retaining tube, each fabricated from a biodegradable material. The first and second retaining tubes are curl-shaped and are connected to two ends of the main tube, respectively. The method of manufacturing a biodegradable double-J stent comprises the steps of: (a) providing a tube made of a biodegradable material; and (b) bending two ends of the tube to render the two ends curl-shaped and keeping a middle segment between the two ends straight. The two curl-shaped ends define a first retaining tube and a second retaining tube, respectively, and the middle segment defines a main tube. The biodegradable double-J stent precludes a ureteral obstruction which might otherwise occur with conventional double-J stents not removed in a timely manner.

Abstract: A water gathering cover has a water gathering element, multiple hole sets and multiple mounting sleeves. Because a cover of a water purification unit and the water gathering element are integrated, the assembling of the water purification device is simplified as follows. A filter cartridge of the water purification unit is mounted in one of the hole sets after being aligned with the hole set. A casing of the water purification unit is mounted around the filter cartridge and is mounted securely to a corresponding mounting sleeve. Then the assembling of the water purification device is completed. As a result, the water gathering cover comprises fewer components, which simplifies the assembling of the water purification device and lowers the cost. Besides, the assembling of the water purification device only needs one round of aligning process.
