Grip strength device
First Claim
1. A device for measuring grip strength of muscles, comprising:
- a removable casing containing a first fluid;
a first bellows having a closed end, the first bellows being in fluid communication with the casing, the first bellows and the casing forming a first fluid system partially filled with the first fluid;
a second bellows containing a second fluid, the second bellows having a closed end abutting the closed end of the first bellows and forming a second fluid system; and
means for measuring and displaying pressure exerted on the second fluid system by the first fluid system when the casing is compressed.

Abstract
The grip strength device is configured to gauge the grip strength of contracted muscles or aid in exercising particular muscles by providing resistance against the contracted muscles. The grip strength device is inserted into a user'"'"'s vagina or held in a user'"'"'s hand. The user either contracts the pubococcygeal or hand muscles depending on the casing used. The grip strength device has a removable casing containing a first fluid, a first bellows, a second bellows and a pressure gauge. The first bellows has a closed end and a first valve in communication with the casing. The second bellows has a second fluid. The second bellows has a second valve connected to the pressure gauge, and a closed end abutting the closed end of the first bellows. Pressure applied to the removable casing is communicated from the first bellows to the second bellows and measured by the pressure gauge.

18. A device for measuring grip strength of muscles, comprising:
-
a removable casing defining a cavity, the casing being compressible; a first fluid disposed within the cavity of the casing; a first bellows having a closed end and having a first valve forming a fluid conduit between the first bellows and the casing cavity; a second bellows having a second valve and having a closed end abutting the closed end of the first bellows; a second fluid disposed within the second bellows; a tube extending from the second valve, the second valve forming a fluid conduit between the second bellows and the tube; a rigid sheath extending axially between the casing and the first and second bellows; and a pressure gauge connected to the tube; whereby pressure applied to the removable casing is communicated from the first bellows to the second bellows and measured by the pressure gauge. - View Dependent Claims (19, 20)
