Ductus venosus is penetrated, ductus venosus is subcutaneously sent to neck point of puncture, is then fed into vena jugularis inferior, and this way changes original
Fixed point, have convenient for fix, the advantages of not affecting the appearance, but be placed in ductus venosus there are certain difficulties.
Utility model content
The utility model to solve the above problems, devises a kind of novel deep vein puncture guiding tube, this draws
Guide-tube structure is simple, easy to use, and guiding tube front end will not give a discount in bending, facilitates merging vein to lead by the guiding tube
Pipe, to change the fixed point of ductus venosus, is fixed convenient for ductus venosus, is not affected the appearance after fixed.
In order to achieve the above technical purposes, reach above-mentioned technical effect, the utility model is real by the following technical programs
Existing:
A kind of novel deep vein puncture guiding tube, including guiding tube tube body, holding end and gripping tab, the guiding tube tube body
Including tube body main body and the vertebra shape front end for being connected to tube body body front end, the long 3-6 ㎜ in vertebra shape front end, outside the tube body main body
Wall is equipped with scale, is embedded with spring, the long 15-20 ㎜ of spring in tube body body front end tube wall, tube body body rear is fixed with column
Holding end, holding end side wall is fixed with the gripping tab of sheet, and the holding end is provided with the channel of left and right perforation, channel and guidance
The connection of pipe tubular body, the channel is gradually increased from left to right.
Further, the guiding tube tube body is made of medical PVC.
Further, the guiding tube tube length is 15-20 ㎝.
Further, the holding end outer wall and gripping tab surface are equipped with anti-sliding burr.
The beneficial effects of the utility model are: the guiding tube structure is simple, and it is easy to use, it is subcutaneously led using the guiding tube
Silk is sent to ductus venosus puncture, and then by the guiding tube convenient for merging ductus venosus, which is vertebra shape,
Resistance can be reduced when puncturing, tube body body front end is embedded with spring, when guiding tube will not be sent out when neck point of puncture is bent
Raw to give a discount, tube body body outer wall is equipped with scale, observes insertion depth convenient for doctor, facilitates doctor by setting holding end and gripping tab
Raw to hold, the channel of holding end is gradually increased from left to right, and ductus venosus is facilitated to be inserted into, and vein can be changed by the guiding tube and lead
The fixed point of pipe is fixed convenient for ductus venosus and is not affected the appearance after fixing.
