け取扱者の負担が減り患者の安全性が向上する。 As explained above, according to the balloon catheter for intrapulmonary artery balloon pumping according to the present invention,
A pumping balloon is provided on the rear end side of the small balloon in the vicinity of the small balloon of the catheter having a small balloon at the tip, and physiological saline is injected into the catheter for measuring the right cardiac output flow rate by thermodilution method. In addition, a thermistor for measuring the right cardiac output flow rate and a measurement hole for measuring pulmonary artery pressure by the thermodilution method are provided, which are located near the pumping balloon, so that balloon pumping within the pulmonary artery is possible. Since both measurement and right cardiac output flow rate measurement can be performed with a single catheter, the catheter can be easily removed, which reduces the burden on the operator and improves patient safety.
