<p>PURPOSE:To reduce dimension and realize the measurement having high precision by transmitting the pressure of the liquid which is transmitted through a catheter and conduit to a semiconductor pressure sensor and measuring the blood pressure. CONSTITUTION:As for a disposable blood pressure transducer, a catheter inserted into the vein of the patient is connected with a conduit 1, and the blood pressure pulsation is transmitted to the medical liquid such as physiological salt water filling the catheter and the conduit 1, and transported to the die of a semiconductor pressure sensor arranged inside a housing 2 having a blade part 2A for fixation, and the blood pressure pulsation is known. A flushing device 3 carried out the adjustment of the flow rate of the medical liquid, and the flow rate is increased by pushing a button 4. Each edge of the plastic conduit 1 is a lure lock type connection mechanism, and the tube of the catheter and a tube for medical liquid can be easily connected, and the female screw 5 of the lure lock is installed at one edge, and the male screw 6 of the lure lock is installed at the other edge. Further, a three-way cock 7 is connected with the conduit 1, and the flow passage for medical liquid can be changed.</p> |
