Lymphatic pressure-measuring system and method for controlling same

摘要

The present invention has an object to measure lymphatic pressure with more safety and ease at lower cost. To achieve this, a lymphatic pressure-measuring system 1 includes: a manchette 11 fitted on a vital observation portion; a measurement unit 13 that measures and outputs pressure of the manchette 11; an infrared camera 21 that detects fluorescence emitted from fluorescent dye previously injected into a lymph vessel in the vital observation portion; and an image processing device 22 that generates and displays an image showing a position of the fluorescent dye in the lymph vessel based on a detection result of the infrared camera 21. The infrared camera 21 repeats the detection while the pressure of the manchette 11 decreases from first pressure to block a lymph flow in the vital observation portion to second pressure at restart of the lymph flow. The measurement unit 13 repeats the measurement during the period.

1. A lymphatic pressure-measuring system comprising:
a manchette fitted on a vital observation portion; a measurement device that measures and outputs pressure of the manchette; a camera that detects fluorescence emitted from fluorescent dye previously injected into a lymph vessel in the vital observation portion; and a monitor that generates and displays an image showing a position of the fluorescent dye in the lymph vessel based on a detection result of the camera, wherein the camera repeats the detection while reducing the pressure of the manchette so as to decrease from a first pressure to block a lymph flow in the vital observation portion to a second pressure at restart of the lymph flow, wherein the measurement device repeats the measurement while reducing the pressure of the manchette so as to decrease from the first pressure to the second pressure which is measured as a lymphatic pressure, at least a part of the manchette is formed of a transparent member so that the fluorescence can pass through, and the transparent member of the manchette comprises a scale in a direction of the lymph flow.
