Filming method of probe by filling way and probe thereof

A filming method of probe by filling way, the probe comprises a rigid member, two ends of the rigid member are permeable, and a mounting hole is defined in one end of the rigid member, the other end of the rigid member is wedge-shaped;

• the method is for film-forming on the probe, and the method comprising:
• (1) spraying at least one hydrophilic matrix material on the outer wall of rigid member;
• (2) injecting hot molten liquid polyethylene glycol into the inner of the rigid member to condense the polyethylene glycol until the polyethylene glycol is filled and overflowed the notch of the wedge surface of the rigid member;
• (3) cutting out the solid polyethylene glycol which projects out of the wedge surface after the polyethylene glycol is cooled, and letting the cutting surface and the perimeter of the rigid member to be formed in a smooth plane;
• (4) inserting the wedge end of the rigid member into a liquid latex vertically for immersion first, picking up the rigid member and dripping residue on the rigid member second, air drying the adhesive layer of the rigid member to let the liquid latex which is covered on the surface of on the rigid member to be a latex film third;
• and
• (5) setting the wedge end of the rigid member upwardly, heating the latex film to vulcanize for obtaining a detecting film, melting the solid polyethylene glycol and letting the polyethylene glycol drain away at the same time.
