the check valve 101 is generally made of an elastic material, and has a slit at its center for receiving the tube bundle 120 therethrough;
the one-way valve can enable channels such as a collection terminal and a tube bundle to be formed, but can block the outflow of blood and the like;
the signal acquisition element 110 comprises an acquisition element body and an acquisition terminal;
the collecting terminals are a plurality of elastic structures which are bent outwards, namely, when the collecting terminals are bound in the tube, the collecting terminals are compressed due to elasticity, and when the collecting terminals are released, the collecting terminals are directly ejected out of the ingress tube and are uniformly arranged outside the head end of the ingress tube in a scattering shape, so that the effect of attaching to the inner wall of a blood vessel is realized;
it is noted that, since the collecting terminal is in an outward curved shape, as shown in fig. 4 and 5, when the inner wall environment changes, the collecting terminal can automatically attach to the shape of the inner wall of the blood vessel based on elasticity, thereby solving the change situation of the inner wall environment.
As shown in fig. 3, the collecting terminal 111 is provided with a pressure sensor for sensing pressure and a position sensor for sensing the positioning of the collecting terminal, and has the function of transmitting the pressure value of the inner wall of the blood vessel collected by the collecting terminal and the position of the collecting terminal to the terminal in real time or at fixed time in the process of moving the collecting terminal;
the sensor can be a miniature device or an integrated structure which is directly sold on the market, is arranged at the tail end of the acquisition terminal, and the sensing end faces the vessel wall.
As shown in fig. 1, the handle 200 is provided with a chute 210 (which may have graduations thereon), one end of a guiding handle 220 is connected with the tube bundle 120 (i.e., the tube bundle structure for accommodating the signal wires of each collecting terminal and the elastic steel wire for guiding), and the other end extends out of the chute 210, and the signal collecting body, especially the collecting terminal thereof, is slidably disposed in the interior of the guiding tube 100 by sliding the guiding handle 220 in the manner that the guiding handle 220 slides in the chute 210, and the use process is that the guiding handle 220 is located at the far-end before the guiding tube 100 reaches the designated destination, when the guiding tube reaches the designated destination, the guiding handle is pushed forward as shown in fig. 2, the collecting terminal pops out the head end of the guiding tube, and when the collecting of the signal is completed, the guiding handle continues to push the guiding handle into the far-end, so that the collecting terminal is retracted in the guiding tube, and then the human body is pulled out.
