The invention relates to a human body plasticization nursing teaching specimen and a producing method thereof. The producing method comprises the following steps of material drawing, anti-corrosive perfusion, dissection, bleaching, deprivation, defatting, vacuum gum dipping, shaping and solidification. Human specimens without skin injury, fracture or lesion are selected. During dissection, the center of the skin is cut sagittally to dissect superficial fascia of the skin. Deep muscle vessels and nerves are shown on one side, and the skin, the superficial fascia, superficial muscles and vascular nerves are shown on the other side. During shaping, the specimen is shaped with steel bars, and positioning on the specimen is conducted based on common nursing positions. After positioning, the tissue structure is opened from shallow to deep according to the hierarchical structure of the specimen. Puncturing / cannula inserting is conducted at the nursing positions with nursing instruments. Afterinstallation of nursing instruments, solidification is carried out. Compared with the prior art, needle inserting and cannula inserting are displayed directly, education of teachers and study of students are convenient, and reference basis for clinical nursing technique operation is provided.

An intravascular catheter for peri-vascular nerve activity sensing or measurement includes multiple needles advanced through supported guide tubes (needle guiding elements) which expand with open ends around a central axis to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the perivascular space. The system also may include means to limit and / or adjust the depth of penetration of the needles. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. The addition of an injection lumen at the proximal end of the catheter and openings in the needles adds the functionality of ablative fluid injection into the perivascular space for an integrated nerve sending and ablation capability.
