It further includes a rotating structure 4, a locking structure 5 and a power supply assembly 6 disposed on the first finger clip 1. The power supply assembly 6 is fixedly connected to the rotating structure 4. The power supply assembly 6 includes a power supply slot 61 and a flexible transmission line 62 electrically connected between the power supply slot 61 and the sensor. The locking structure 5 is used to lock the rotating structure 4. When it is necessary to measure the blood oxygen of a patient, rotate the rotating structure 4 to change the power supply slot 61 to a suitable direction, operate the locking structure 5 to lock the rotating structure 4 and fix the direction of the power supply slot 61. Press the rear parts of the first finger clip 1 and the second finger clip 2 to open the front parts of the first finger clip 1 and the second finger clip 2 and clip them onto the patient's finger. Insert the power cord into the power supply slot 61 and connect the other end of the power cord to a cardiac monitor, thereby realizing the power supply and data transmission of the blood oxygen clip. This enables the blood oxygen clip to be worn without being limited to one direction, and flexibly adjust the connection direction and angle between the blood oxygen clip and the cardiac monitor at multiple angles, with strong clinical practicability. When applicable to patients wearing restraint mittens, the zipper at the finger end of the restraint mitten can be opened, the blood oxygen clip can be put on from the fingertip, and then the zipper can be zipped up for restraint.

[0022] Specifically, the rotating structure 4 includes a first hollow tube 41 and a second hollow tube 42 provided on the first finger clip 1, and a vertical tube 43 rotatably connected to the hollow tubes. The middle and lower part of the vertical tube 43 is located inside the first hollow tube 41. A spring 44 is provided on the second hollow tube 42. The middle and lower part of the vertical tube 43 abuts against the top of the spring 44, and the other end of the spring 44 abuts against the top of the first finger clip 1. The flexible transmission line 62 is located inside the second hollow tube 42. The locking structure 5 includes a button 51 provided on the middle side wall of the first hollow tube 41, and a protruding part 52 whose expansion and contraction is controlled by the button 51. A plurality of tooth grooves 45 are circumferentially provided in the middle of the vertical tube 43, and the protruding part 52 is cooperatively connected with the tooth grooves 45. A first limiting member 46 is provided on the inner side wall of the upper part of the first hollow tube 41, and a second limiting member 47 is provided on the outer side wall of the upper part of the vertical tube 43. The first limiting member 46 is used to limit the excessive rotation of the vertical tube 43. The diameter of the middle and lower part of the vertical tube 43 contracts inward to form a first inclined surface 48, and a second inclined surface 49 that fits the first inclined surface 48 is provided at the top of the second hollow tube 42; by rotating the power socket 61 to drive the vertical tube 43 to rotate, when it rotates to an appropriate angle, press the vertical tube 43 downward. The vertical tube 43 pushes the spring 44 to contract until after the vertical tube 43 descends, when the first inclined surface 48 of the vertical tube 43 contacts the second inclined surface 49 of the second hollow tube 42, the vertical tube 43 cannot continue to descend, and the tooth grooves 45 in the middle of the vertical tube 43 are directly opposite to the protruding part 52.
