Abstract
A finger pressure gauge capable of checking finger pressure conveniently and scientifically includes an inner case having a guide pin and a rack, an outer case receiving the inner case and having a pinion corresponding to the rack, wherein the inner case and outer case are retained by an elastic spring provided between them, and a dial covered with a window to show the finger pressure with a hand connected to the pinion, by which a patient can check on his recovery rate during curing by Chinese medicine.
Claims19
A finger pressure gauge for checking finger pressure, comprising:
- an inner case including:
- a guide pin extending therefrom,
- and a rack formed on one side thereof, and
- an upper surface for receiving a first finger of a person,
- an outer case for slidable receiving the inner case therein, said outer case including:
- guide groove means for receiving the guide pin for sliding movement therein and for limiting slidable movement of said inner case relative to said outer case,
- protruded portion means for slidably receiving said rack therein,
- pinion means, rotatably mounted in said protruded portion means, for meshing with said rack, and
- a lower surface for receiving a second finger of a person such that said inner and outer cases can be biased toward each other between the first and second fingers when pressure is applied by the first and second fingers on the upper and lower surfaces,
- a hand connected with said pinion means for rotation therewith,
- spring means for biasing said inner case and said outer case apart, and
- dial means mounted to said protruded portion means for displaying a measurement of finger pressure in conjunction with said hand when fingers of a person depress said inner case into said outer case against the force of said spring means.
