Physiological signal monitoring device

A physiological signal monitoring device comprising:

• a base (1) that includes a bottom plate (111) adapted to be mounted to a skin surface of a host, and an inner surrounding wall (114) protruding from a top surface (115) of said bottom plate (111), said top surface (115) and said inner surrounding wall (114) cooperatively defining a mounting groove (113) therebetween;
• a biosensor (2) that includes
• a mounting seat (21) mounted to said mounting groove (113) and having an outer surrounding surface (213), and
• a sensing member (22) carried by said mounting seat (21) and adapted to be partially inserted underneath the skin surface of the host in an inserting direction (D4) for measuring at least one analyte of the host and to send a corresponding physiological signal;
• a transmitter (3) that is removably mounted to said base (1) in the inserting direction (D4), that is for receiving and transmitting the corresponding physiological signal, and that has a bottom portion (31), said bottom portion (31) facing said base (1) when said transmitter (3) is mounted to said base (1) so as to allow said mounting seat (21) to be disposed between said base (1) and said transmitter (3) and to allow said sensing member (22) to be directly coupled to said transmitter;
• and
• a sealing unit (4) that includes a plurality of sealing members for sealing at least one liquid leakage pathway, said plurality of sealing members including
• a first sealing member (42) clamped between said mounting seat (21) of said biosensor (2) and said bottom portion (31) of said transmitter (3) for sealing a first liquid leakage pathway (a) that extends toward where said sensing member (22) is coupled to said transmitter (3), said first sealing member (42) of said sealing unit (4) abutting against an upper end of said inner surrounding wall (114) of said base (1),
• a second sealing member (41) clamped between said inner surrounding wall (114) of said base (1) and said transmitter (3) for sealing a second liquid leakage pathway (b), and
• a third sealing member (48) clamped between an inner peripheral surface of said inner surrounding wall (114) of said base (1) and said outer surrounding surface (213) of said mounting seat (21) for sealing the first liquid leakage pathway (a).

• a base-sensor sealing member (48) clamped between an inner peripheral surface of said inner surrounding wall (114) of said base (1) and said outer surrounding surface (213) of said mounting seat (21) for sealing the first liquid leakage pathway (a) alongside said first sealing member (42), and
• a through-hole sealing member (44) mounted to a top portion (214a) of a fitting hole (214) of said mounting seat (21) for sealing an implantation path (c) that is cooperatively defined by said fitting hole (214) of said mounting seat (21) and a through hole (18) of said bottom plate (111) of said base (1) and for preventing a body liquid from entering an inner space (30) of said transmitter (3).
