Physiological signal monitoring device and sensor holder thereof

1. A physiological signal monitoring device for implantation under a skin of a living body to measure a physiological signal of an analyte in a biological fluid from the living body, comprising:

a sensor having a signal detection end and a signal output end, wherein the signal detection end is to be implanted under the skin to detect the physiological signal, and the signal output end is to output the physiological signal;

a transmitter having a port connected to the signal output end and receiving the physiological signal, wherein the port comprises a connecting slot; and

a holder carrying thereon the sensor, the holder having a top positioned lower than a top of the signal output end such that the signal output end protrudes beyond the holder and is held within the connecting slot, and the holder comprising:

an implantation hole being a channel for implanting therethrough the sensor, and containing a part of the sensor; and

a containing indentation containing the signal output end, wherein the containing indentation has a surrounding wall kept apart from the signal output end to define a space such that the port is received within the space of the containing indentation, and the signal output end is electrically connected to the port.

2. The physiological signal measuring device as claimed in claim 1 , further comprising a base, wherein the holder comprises two positioning holes, and the base comprises two positioning pillars contained in the two positioning holes.

3. The physiological signal measuring device as claimed in claim 1 , wherein the holder further comprises a waterproof seal disposed above the implantation hole and abutting against the transmitter to form therebetween a waterproof sealing structure.

4. The physiological signal measuring device as claimed in claim 1 , wherein the holder further comprises an elastic divider disposed in the implantation hole to separate the implantation hole and covering all over a cross-sectional area of the implantation hole.

5. The physiological signal measuring device as claimed in claim 4 , wherein the elastic divider is disposed above the sensor in the implantation hole.

6. The physiological signal measuring device as claimed in claim 1 , wherein the holder comprises a limiter for restricting the sensor.

7. The physiological signal measuring device as claimed in claim 6 , wherein the limiter comprises a hook portion or a pressing portion.

8. The physiological signal measuring device as claimed in claim 1 , wherein the implantation hole and the containing indentation are respectively positioned along two different longitudinal axes.
