Title:
INFUSION SOLUTION INJECTION DEVICE AND INFUSION SOLUTION INJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/189750
Kind Code:
A1
Abstract:
The present invention provides an infusion solution injection device 100 for injecting an infusion solution 50 to a patient through a tube 120, the infusion solution injection device comprising a pump 110, a light-scattering material introduction unit 130 that introduces a liquid including an optically measurable light-scattering material 52 to the tube 120, an optical measurement sensor 160 that is disposed in a position downstream of the pump 110, and a computation unit 172. The optical measurement sensor 160 measures the flow speed of the light-scattering material 52 flowing inside the tube 120. The computation unit 172 computes an injection amount of the infusion solution 50 to the patient on the basis of the flow speed of the light-scattering material 52 measured by the optical measurement sensor 160. According to the infusion solution injection device 100 of the present invention, it is possible to accurately and stably control the injection amount of the infusion solution even when the injection amount of the infusion solution to the living body is very small.
