(3) Placing an intermediate rubber supporting ring in an annular plate of a protective shell and contacting with the inner wall of the annular plate, contacting the inner wall of the top surface of a pulse contact surface on the protective shell with a top pressure sensor of a sensor main body, and then adjusting the annular plate to enable the sensor main body to be outgoing along a limiting plate;
(4) Placing a microprocessor between the upper layer of TPU material and the lower layer of TPU material, and welding the two layers of TPU material together along the edge through high frequency waves to form a closed air bag;
(5) The air pump is welded on the closed air bag through high frequency, the air inlet of the air pump is communicated with the outside, and the air outlet is communicated with the inside of the air bag;
(6) Two parts of the two magic tapes which are adhered to each other are respectively welded on the corresponding sides of the air bags;
(7) The bottom surface of the bottom shell on the protective shell sleeved with the sensor main body is contacted with the outer side surface of the air bag, and the bottom shell is welded on the air bag along the outer peripheral edge of the bottom shell through high-frequency welding;
(8) Cutting by an upper cutting machine to form the final air bag type pulse probe.
10. A method of using a balloon pulse probe according to any one of claims 1-8, comprising the steps of:
(1) Firstly, a pulse wave contact surface is contacted with the pulse of a patient, and an air bag is wound on a wrist by using a magic tape;
(2) Starting an air pump, and inflating the air bag by using the air pump, so that the air bag presses the protective shell, and the pulse wave contact surface is tightly attached to the pulse of a patient;
(3) The microprocessor is utilized to sense pressure signals received by the pressure sensor at the top of the sensor main body, the air pump is controlled to perform corresponding inflation or deflation after the pressure signals are analyzed, the air pump is controlled to perform deflation to reduce air pressure when the pressure is high, and the air pump is controlled to perform inflation to increase the air pressure when the pulse signals are weaker.
