Device for draining lymph into vein

摘要

The present invention relates to a device for draining lymph into vein, which comprises: a storage chamber including a chamber wall, wherein a storage space formed by the chamber wall, and at least one first opening and a second opening are formed on the chamber wall; at least one osmosis membrane disposed at the first opening so that lymph can penetrate into the storage space, wherein the osmosis membrane is made of negative charged polymer molecules; a first conduit, of which one end connects to the storage space, and the other end connects with a vein so that the space can connect with the vein; and a pump provided in the storage chamber, wherein a negative pressure in the storage space is generated by the pump to drain lymph into the vein.

1. A device for draining lymph into vein, comprising:
a storage chamber, comprising a chamber wall, wherein the chamber wall extends to form a storage space, and the chamber wall has a plurality of first openings that circle around the chamber wall and a second opening formed thereon; a plurality of osmosis membranes, which are made of a negatively charged polymer molecule material, the osmosis membranes circle around the chamber wall and are configured at the first openings to allow lymph to permeate into the storage space of the storage chamber solely via the osmosis membranes, wherein a pore diameter of the osmosis membrane is between 20 nm to 50 nm; a first conduit, of which one end is connected to the storage space of the storage chamber via the second opening, and another end is adapted to be connected to a vein, so as to allow the storage space of the storage chamber to connect to the vein; and a pump, which is configured in the storage chamber, wherein the pump operates to generate a negative pressure to make a pressure inside the storage space smaller than a pressure outside the storage space, the device being thereby configured to guide the lymph from outside the storage space into the inside of the storage space, and to drain the lymph into the vein through the first conduit; wherein the device for draining lymph into vein is adapted to be implanted in a subcutaneous fat layer; wherein the diameter of the device is between 1 to 5 centimeters.
