Abstract

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.

Claims

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 at least one first opening and a second opening formed thereon;

at least one osmosis membrane, which is made of a negatively charged polymer molecule material, and is configured at the first opening to allow lymph to permeate into the storage space of the storage chamber;

a first conduit, of which one end is connected to the storage space of the storage chamber, and another end is connected to a vein, so as to connect the storage space of the storage chamber 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 so as 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.

2. The device of claim 1, wherein the pump comprises an entry terminal and an exit terminal, the lymph permeating into the storage space of the storage chamber drains from the entry terminal to the exit terminal, and drains into the vein through the first conduit.

3. The device of claim 2, wherein the pump is configured in the storage space of the storage chamber, and the exit terminal is connected to the second opening.

4. The device of claim 2, wherein the pump is configured on an outside of the storage chamber, and the entry terminal is connected to the second opening, and the exit terminal is connected to the first conduit.

5. The device of claim 4, wherein the pump further comprises a second conduit, and the entry terminal is connected to the second opening through the second conduit.

6. The device of claim 4, wherein the pump is a detachable pump.

7. The device of claim 5, wherein the pump is a detachable pump.

8. The device of claim 1, wherein the pump is a micro pump, a peristaltic micro pump, or a manual micro pump.

9. The device of claim 5, further comprising an anti-reflux valve, which is configured at the second opening, the first conduit, the second conduit, or a combination thereof.

10. The device of claim 1, wherein a biocompatible material covers the periphery of the lymph draining device.

11. The device of claim 10, wherein the biocompatible material is one selected from the group consisting of:

silicone, silicone rubber, polyethylene, polytetrafluoroethylene, polyurethane, polydimethyl siloxane, polylactic acid, polyglycolic acid, niobium-titanium-zirconium β

alloy, titanium alloy metal, gold, silver, cobalt-chromium-molybdenum alloy, and poly (hydroxyethyl methacrylate).

12. The device of claim 1, wherein a diameter of the first conduit is between 1 mm to 2 mm.

13. The device of claim 1, wherein a pore diameter of the osmosis membrane is between 20 nm to 50 nm.

14. The device of claim 1, wherein the negative pressure generated by the pump in the storage space is between 10 mmHg to 30 mmHg.

15. The device of claim 1, further comprising a drug injection silicone piece, which is configured on the storage chamber to allow a drug to be injected into the storage space of the storage chamber through the drug injection silicone piece.

16. The device of claim 1, further comprising at least one fixing ring, wherein the fixing ring is configured on an outside of the storage wall of the storage chamber.
