Document Type and Number:
WIPO Patent Application WO/2023/216767
Kind Code:
A1
Abstract:
Provided is a dual-layer syringe device for grainy fat purification. An outer syringe (1) comprises: an outer cylinder (4), and an outer syringe push rod (6) and an outer syringe piston (8) which are arranged in the outer cylinder (4). The outer syringe piston (8) is arranged at a top end of the outer syringe push rod (6). The outer syringe push rod (6) and the outer syringe piston (8) are each provided with an open port. An inner syringe (2) comprises an inner cylinder (5) arranged in the outer syringe push rod (6). A top end of the inner cylinder (5) is provided with a second port (13). The second port (13) is detachably connected to the open port of the outer syringe push rod (6). The outer syringe piston (8) and the outer syringe push rod (6) are both provided with an open port. The second port (13) of the inner syringe (2) is detachably connected to the open ports and is in communication with the outer syringe (1) by means of the open ports. The outer syringe (1) is connected to a sealing cap (3) to form a unique closed centrifugal device. The present invention solves the technical problem that existing purification modes are tedious in operation and prone to contamination which may affect the safety of purified grainy fat after use.
