<p>A finger-clipped oximeter comprises an upper housing (1) and a lower housing (2) which are oppositely arranged; one of the upper housing (1) and the lower housing (2) is provided with a guide post (4), and the other one is provided with a reset spring (6); a free end of the guide post (4) is connected with the reset spring (6); when the upper housing (1) and the lower housing (2) open, the guide post (4) presses on the reset spring (6) to make it elastically deform; a clamping force is generated between the upper housing (1) and the lower housing (2) by the elastic deformation to clamp the measured finger. The finger-clipped oximeter of the invention has advantages of easy installation and durable use etc.</p>
