Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings for better understanding of the technical solution.

As shown in fig. 1, 3, the utility model relates to a simple and easy fixing device of navel vein catheterization, including vein catheterization, the one end of vein catheterization stretches into in the navel vein, and is provided with the scale mark on the vein catheterization's of this end outer wall, so that insert suitable length, infusion set is connected to the other end, for placing from navel vein opening part toward outer infiltration liquid behind the catheterization, it is provided with the shutoff piece to slide to cup joint on vein catheterization's outer wall, this shutoff piece is and is the round platform form, a shutoff for the vein mouth, the direction that the installation diameter increases in proper order gets into navel vein opening part gradually, carry out the shutoff.

As shown in fig. 1 and 2, in order to realize the convenient and fast fixing of the vein catheterization, the outer wall of the vein catheterization is further provided with a catheterization fixing part in a sliding and sleeving manner, and the specific structure of the catheterization fixing part is as follows: including sliding sleeve, along the outside connection piece that extends of sliding sleeve terminal surface integral type, the connection piece is provided with threely, divide trisely along sliding sleeve circumference, fix umbilical cord and vein catheterization for the realization, keep away from sliding sleeve's one end at the connection piece and bend to sliding sleeve central direction and form the portion of bending, the tip equipartition of the portion of should bending is provided with a plurality of latches, latch on the three connection piece is with umbilical cord outer wall card jail, for the effect of further realization connection piece chucking, both sides at every connection piece all are provided with lug and recess, the lug of a connection piece one side sets up with the recess cooperation joint of adjacent connection piece. Realize the mutual joint cooperation of connection piece, still cup joint simultaneously and be provided with the elastic fixation circle in one of sliding sleeve is close to the connection piece, and this elastic fixation pipe can be used to the fastening of latch end.
