Abstract

The present invention discloses a finger-clipped oximeter comprising: an upper case (2) in which a measuring element (4), a data processing circuit, batteries (6) and a display (3) are provided, a rectangular through hole being provided in the upper case (2); a finger pressed plate (10) in which a measuring element is also provided, a finger inserting hole (11) being formed between an upper surface of the finger pressed plate (10) and a lower surface of the upper case (2), a rectangular column (7) with a position corresponding to that of the rectangular through hole of the upper case (2) being provided on the finger pressed plate (10); and a pair of connectors which are capable of ascending or descending, each of the connectors including one U-shaped connecting rod (8), a middle portion of the U-shaped connecting rod (8) being a straight portion which extends through an edge portion on a side of the finger pressed plate (10), two arm portions of the U-shaped connecting rod (8) being inserted into the upper case (2) to serve as a connecting piece between the upper case (2) and the finger pressed plate (10).

Claims

1. A finger-clipped oximeter, characterized in that the finger-clipped oximeter comprises:

an upper case in which a measuring element, a data processing circuit, batteries and a display are provided, a rectangular through hole being provided in the upper case;

a finger pressed plate in which a measuring element is also provided, a finger inserting hole being formed between an upper surface of the finger pressed plate and a lower surface of the upper case, a rectangular column with a position corresponding to that of the rectangular through hole of the upper case being provided on the finger pressed plate; and

a pair of connectors which are capable of ascending or descending, each of the connectors including one U-shaped connecting rod, a middle portion of the U-shaped connecting rod being a straight portion which extends through an edge portion on a side of the finger pressed plate, two arm portions of the U-shaped connecting rod being inserted into the upper case to serve as a connecting piece between the upper case and the finger pressed plate.

2. The finger-clipped oximeter according to claim 1, characterized in that the middle portion of the U-shaped connecting rod is pressure-cast to an edge portion on a side of the finger pressed plate.

3. The finger-clipped oximeter according to claim 2, characterized in that at least a portion of the middle portion of the U-shaped connecting rod has a structure which can prevent the U-shaped connecting rod from being rotated with respect to the finger pressed plate.

4. The finger-clipped oximeter according to claim 3, characterized in that at least a portion of the middle portion of the U-shaped connecting rod is made into a pyramid shape or is provided with fins.

5. The finger-clipped oximeter according to claim 1, characterized in that at least one column like portion which extends straight up is provided at each of four corners of an upper surface of a bottom wall of the upper case, and positions of the two arm portions of the U-shaped connecting rod are limited by the at least one column like portion.

6. The finger-clipped oximeter according to claim 1, characterized in that the upper case has a top cover.

7. The finger-clipped oximeter according to claim 1, characterized in that the finger pressed plate is made of plastics or silica gel.

8. The finger-clipped oximeter according to claim 1, characterized in that a V-shaped portion which extends toward the middle portion of the U-shaped connecting rod is provided at each end of the two arm portions of the U-shaped connecting rod.

9. The finger-clipped oximeter according to claim 8, characterized in that the V-shaped portion is opened toward two sides of the U-shaped connecting rod, or is opened toward the straight portion in the middle portion of the U shaped connecting rod.

10. The finger-clipped oximeter according to claim 1, characterized in that one movable magnet is provided at each end of the two arm portions of the U-shaped connecting rod, while one stationary magnet is provided at each root of the two arm portions of the U-shaped connecting rod, and the movable magnet and the stationary magnet are provided so that magnetic poles with the same polarity are opposed to each other.
