Abstract
An infusion state detection system includes: a pump unit configured to deliver a liquid in an infusion line; a pressure detector configured to detect a pressure in the infusion line; and a determination processing unit configured to: when the pressure detected by the pressure detector is at a predetermined value or above, stop driving of the pump unit for a stop period, and determine an infusion state on the basis of a value of the pressure detected by the pressure detector during the stop period.
Claims9
An infusion state detection system comprising:
- a pump unit configured to deliver a liquid in an infusion line;
- a pressure detector configured to detect a pressure in the infusion line;
- and
- a determination processing unit configured to:
- when the pressure detected by the pressure detector is at a predetermined value or above, stop driving of the pump unit for a stop period, and
- determine an infusion state on the basis of a value of the pressure detected by the pressure detector during the stop period.
An infusion state detection system comprising:
- a liquid delivery pump configured to deliver a medicinal solution in a medical bag to a patient via an infusion line and an indwelling needle;
- a pressure sensor configured to be fixed to a body surface of the patient at a position proximate the indwelling needle and configured to detect a pressure inside the infusion line;
- and
- a determination processing unit configured to:
- when the pressure detected by the pressure sensor is at a predetermined value or above, stop driving of the liquid delivery pump for a stop period, and
- determine an infusion state on the basis of a value of the pressure detected by the pressure sensor during the stop period.
An infusion state detection system comprising:
- a liquid delivery pump configured to deliver a medicinal solution in a medical bag to a patient via an infusion line and an indwelling needle, the liquid delivery pump comprising a pressure detector;
- a pressure sensor configured to detect a pressure inside the infusion line;
- and
- a determination processing unit configured to:
- determine the presence or absence of an occlusion phenomenon of the infusion line using a pressure value detected by the pressure detector, and
- determine whether the indwelling needle is dislocated from a blood vessel using a pressure value detected by the pressure sensor.
