The utility model discloses the one end that the disc was kept away from to the body sets up radial through-hole, and radial through-hole can increase the displacement, also prevents that carminative head end from stifled flat.

The utility model discloses an one end of first sheath is sealed the other end and is the socket, the one end of second sheath is sealed the other end and is the bellmouth, the disc setting of outer tube is on the step of second sheath bellmouth department, and the socket cooperation of first sheath is inserted in the bellmouth of second sheath. The disc is arranged on the step at the socket of the second sheath, and the distance is reserved between the needle point and the closed end of the second sheath, so that the needle point can be protected.

The utility model is characterized in that the closed end of the second sheath is inserted with a protective cap, and the protective cap is provided with a vent hole; a clamping block is integrally arranged on one side surface of the disc of the outer sleeve facing the threaded seat, and the outer diameter of the clamping block is matched with the inner diameter of the protective cap; when the pneumothorax puncture needle is not used, the protective cap is fixed on the second sheath; after puncture, the protective cap is fixed on the fixture block. When the outer sleeve is left on the chest wall, the protective cap on the second sheath is taken down and fixed on the fixture block, the protective cap is breathable, and the clothes or the bedding can be prevented from being scratched.

The utility model discloses fixed connection pen clip on the first sheath conveniently presss from both sides the protective sheath on medical personnel's clothes pocket.
