Abstract: A gage mechanism for a blood pressure measuring device or other similar apparatus includes a supported shaft member (96) having one end in contact with an inflatable bellows (34). A pointer (92) is attached at an opposite end of the shaft and a helically wound ribbon spring (106) is attached to the shaft and a supporting structure (122). As the bellows inflates, the shaft is axially displaced and causes rotation due to the constraint of the helical ribbon spring, causing a corresponding angular deflection of the attached pointer relative to an indicating scale (85). The mechanism includes a first adjustment member (118) for allowing the pointer to be preset to a zero or calibrated position, and a second adjustment mechanism that controls the amount of angular rotation of the shaft and pointer for a displacement of the bellows.

Abstract: An apparatus for measuring a physical quantity or parameter includes a housing having a supportably mounted shaft member. A first end of the shaft member is placed in proximity with the output of a displacement device which is responsive to a change in the physical quantity. A ribbon spring member is coaxially disposed and wound helically about the supported shaft member, one end of the spring member being attached to the shaft and a remaining end to a supporting structure. Based on a change in the physical quantity, (pressure, velocity, temperature, etc.), the output of the displacement device engages the shaft member, which axially displaces and rotates due to the constraint of the ribbon spring member. The rotation of the shaft member produces a corresponding angular deflection of an attached pointer relative to readable indicia.

Abstract: A pressure indicator (106) according to the present invention monitors the pressure of the fluid in a vessel (102). One embodiment of the present invention comprises a closed pressurized gas volume (210) behind a dimpled metal diaphragm (208). In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm (208) to hold the diaphragm (208) in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm (208) will overcome the force of the fluid pressure acting on the external surface of the diaphragm (208), thereby moving the diaphragm (208) into a convex geometry. A viewing window (110) disposed in the side of the vessel (102) can be used to view the pressure indicator (106) and determine the shape of the indicator diaphragm (208).

Abstract: A catheter assembly (20) incorporating a pre-biased indicator (22), the assembly includes a catheter (26) having a proximal end (28), a distal end (30), and catheter walls (32) defining a catheter lumen (34). The assembly further includes a base (36) located at the proximal end (28) of the catheter, the base defining an opening to the catheter lumen, the base having a first end (42) and a second end (44). An inflatable balloon (24) having a predetermined fill volume is located at a distal end (30) of the catheter. An inflation valve (46) is located on the base (36); the inflation valve is in fluid communication with the balloon through an inflation lumen (48) defined by the catheter walls (32). The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume.
