Abstract
A device for measuring body fluid pressure, such as blood pressure, muscle compartment pressure, and spinal column pressure, is herein described. An invasive implement is inserted into a body area, and a fluid path extends from the body area into a fluid channel in the device. A valve is used to control the flow of fluid through the device and a pressure sensor is placed adjacent to the fluid channel, with the pressure sensor and/or a sealant gel forming a portion of the fluid channel. With the valve closed, pressure builds in the fluid channel and the pressure sensor detects the resulting pressure, and a pressure transducer and supporting electronics converts and communicates the pressure measurement. With this device the pressure sensor can detect pressure without contacting the fluid, so therefore a pressure can be taken with a minimum of fluid extraction. If fluid extraction is desired, the valve is opened and fluid flows from the body area to a fluid port where the fluid may be collected.
