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, wherein

the soft gum fingerstall oximeter comprises electronic elements which include a data processing circuit board, a measuring circuit board, a test report display screen, operation keys, and a battery, the measuring circuit board includes an emission circuit board and a reception circuit board which are provided opposite to each other, and

the soft gum fingerstall oximeter further comprises a soft silica gel sheath in which all of the electronic elements are provided, said soft silica gel sheath has an opening through which fingers can be inserted into and form a soft gum fingerstall, and the soft gum fingerstall 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.

2. The soft gum fingerstall oximeter without pivot structure according to claim 1, wherein, the emission circuit board is provided inside the soft silica gel sheath on a side in which a measured finger contacts with an inner surface of the soft silica gel sheath in a measurement, and the reception circuit board which is provided opposite to the emission circuit board is provided inside the soft silica gel sheath on a side in which the data processing circuit board is located.

3. The soft gum fingerstall oximeter without pivot structure according to claim 2, wherein, a stainless steel connecting plate which is used to fix and protect all of the electronic elements is imbedded in the soft silica gel sheath, the stainless steel connecting plate is hot pressed to and inserted into the soft silica gel sheath to form a single unit, and the outline of the stainless steel connecting plate varies with profiles of a top surface and side surfaces of the soft silica gel sheath.

4. The soft gum fingerstall oximeter without pivot structure according to claim 1, wherein, a stainless steel connecting plate which is used to fix and protect all of the electronic elements is imbedded in the soft silica gel sheath, the stainless steel connecting plate is hot pressed to and inserted into the soft silica gel sheath to form a single unit, and the outline of the stainless steel connecting plate varies with profiles of a top surface and side surfaces of the soft silica gel sheath.
