The big end end face of described sleeve pipe 4 is parallel with base material adhesive face, and the small end of described sleeve pipe 4 passes through the aperture on base material 3 to lean out, institute
The axis for stating casing 4 is vertical with the big end end face of casing 4；Conduit or puncture needle 5 are inserted into described sleeve pipe 4, are locked with locking nut 6
It is fixed；Barrier paper 1 is opened, by 2 glue surface of base material adhesive and 7 adhesion of skin, fixed sleeving.
A kind of open slot conic screw type medical catheter or puncture needle locator as described above, it is characterised in that：Described
The small end of casing 4 opens up the open slot 405 parallel with axis from top to bottom, and male cone (strobilus masculinus) is arranged at the small end top of the casing 4
401, outer corner angle 404 are arranged at 401 top of male cone (strobilus masculinus), and outer cone thread 402 arranged at lower part, in the small end top of the casing 4
Corner angle 403 are contacted with conduit or puncture needle 5；6 top of locking nut has inner conical surface 601, lower part to have inside tapered thread 602,
Outside is annular knurl face 603, and outer cone thread 402 forms screw thread pair with inside tapered thread 602, and annular knurl face 603 is caught to rotate locking nut
6, when inside tapered thread 602 is moved down along 402 flank of outer cone thread, the outer rib of the inner conical surface 601 and the male cone (strobilus masculinus) 401
Angle 404 contacts, and squeezes the stress surface that inside corner 403 is contacted with conduit or puncture needle 5, conduit or puncture needle 5 is locked, conversely, loose
Convince pipe or puncture needle 5 by patient analysis.
Due to the adoption of the above technical scheme, advantage and good effect possessed by the utility model are：A kind of open slot cone
Screw-type medical catheter or puncture needle locator, pedestal are made of the base material and casing for filling medical adhesive, medical adhesive
Upper covering barrier paper is isolated from the outside；When storage, for the big end of casing between base material and barrier paper, the small end of casing passes through base material
On aperture lean out；In use, throwing off barrier paper, centered on point of puncture, medical adhesive is sticked to the skin around point of puncture
On, the large end face of casing is adjacent to skin, in conduit or puncture needle plug-in-sleeve, is vertically slowly pierced into, resisting sense when needle cutting edge of a knife or a sword disappears
When, it is locked or is unclamped with the cooperation of the taper thread of locking nut and casing, the conical surface and open slot；Locator can guarantee puncture needle
It is vertical to be pierced into skin, ensure the degree that puncture needle enters, prevents plowing from interior tissue, puncture needle is avoided to be swung in human body, hand
Nurse or trainee or manipulator need not be allowed to hold puncture needle tubing always with a hand in art overall process；It is economic, practical, beautiful
Sight, cost be not also high.
