Abstract

The present invention discloses a soft gum fingerstall oximeter without pivot structure, the soft gum fingerstall oximeter comprises a soft gum fingerstall which can wraps around a finger closely with variations of the profile of the finger and causes a clamping force distributed on the clamped portion of the finger uniformly. An emission circuit board and a reception circuit board are provided in the soft gum fingerstall. The soft gum fingerstall of the oximeter is enclosed, which can shield light entering from a side.

Claims

1. A soft gum fingerstall oximeter without pivot structure, characterized in that the soft gum fingerstall oximeter comprises a soft gum fingerstall which wraps around a finger closely with variations of the profile of the finger and causes a clamping force distributed on the clamped portion of the finger uniformly, and an emission circuit board and a reception circuit board are provided in the soft gum fingerstall.

2. The soft gum fingerstall oximeter without pivot structure according to claim 1, further comprising a housing in which electronic elements including a data processing circuit board, a test report display screen, operation keys, a battery, a speaker and a mini USB data output port are provided, and the housing is placed in a side outside of the soft gum fingerstall and is connected to the soft gum fingerstall detachably.

4. The soft gum fingerstall oximeter without pivot structure according to claim 1, wherein, electronic elements including a data processing circuit board, a test report display screen, operation keys, a battery, a speaker and a mini USB data output port are provided in a housing in which horizontal dragging slideways for soft gum slide plates are provided, an upper soft gum fingerstall and a lower soft gum fingerstall are fixed to the soft gum slide plates respectively, while the soft gum slide plates are mounted on the horizontal dragging slideways for the soft gum slide plates in the housing respectively, measuring elements are attached to the soft gum fingerstalls, and the measuring elements attached to the soft gum fingerstalls are connected to an interface circuit board in the housing via a pin socket.

5. The soft gum fingerstall oximeter without pivot structure according to claim 1, further comprising a circuit unit which includes a data processing circuit board, measuring circuit boards, a test report display screen, operation keys and a battery;

and a soft silica gel sheath in which the circuit unit is provided and which has an opening through which fingers can be inserted into, and the measuring circuit boards include an emission circuit board and a reception circuit board which are provided opposite to each other.
