Cap indent, needle body evagination, make tail cap and needle body tail end be relatively fixed, and be easy to firmly press down.An additionally individually designed connection
Device, can connect tail cap and common syringe.An individually designed cap stopper, prevents urine leakage, causes operating difficulties again.
2nd, expanded casing: patent of the present invention provides a kind of expanded casing with self-tapping type not damaged safety screw, design
Length 150mm, head end diameter 4mm, tail end diameter 6-8mm, it is similar to clinical conventional expansion skin device, head end is lossless with self-tapping type
Hinder safety screw, stomach wall can be mitigated during lower companding opens expansion and subside, cause bladder deep tissue injury of blood vessel.Expanded casing
For hard plastic structure, tail end is double ear structure, it is easy to holds and exerts oneself.
3rd, double-jacket tube formula catheter: patent of the present invention provides a kind of double-jacket tube formula catheter, by outer layer sleeve, ring-type rotation
Button, extruding blossom device and inner layer sleeve composition.Design length 300mm, is bilayer sleeve pattern, outer layer sleeve diameter and general
Admittance urinary catheter is identical, provides the catheter of different-diameter according to different patients.Concrete specification such as following table:
Table 1. double-jacket tube formula catheter specification
The catheter that patent of the present invention provides uses the plastic construction slightly harder than ordinary urethral catheter, is bilayer sleeve pattern, outer layer
Sleeve pipe is mainly fixing device, and head end (entering bladder end), with passive expanding umbrella Anti-extrusion device, is bloomed for independent extruding
Formula umbrella-shaped structure, umbrella wing design length as above table (table 1) of umbrella-shaped structure, umbrella-shaped structure tail end uses ring with outer layer sleeve head end
Shape coupling type structure is connected, it is simple to take out in the future.Outer layer sleeve tail end is a ring-like knob, forms spiral shell with inner layer sleeve tail end
Line, knob is also adopted by independent ring-type coupling type structure and is connected with outer layer sleeve, utilizes and press under knob thread, make outer layer sleeve head end
Umbrella-shaped structure struts.During independent knob is pressed under rotation, whole outer layer sleeve will not be made to rotate together.Inner layer sleeve is main
For drainage system, head end is central column bulging structure, design length 8mm, and annulated column head end diameter is less than outer layer sleeve diameter 1mm,
Tail end diameter is identical with outer layer sleeve diameter, and such head end more carefully facilitates insertion into bladder, and tail end then reaches to prop up umbrella-shaped structure
Purpose.Inner layer sleeve tail end can connect common urine collection bag, and tail end bottom and outer layer sleeve knob junction are thread-like structure, spiral shell
Line length determines according to umbrella chord degree, so that the umbrella wing reaches maximum area.The bottom of thread, with locking screw thread, prevents from sliding voluntarily
De-.During taking-up, reversely rotate outer layer sleeve tail end ring-like knob, utilize screw thread pulling force to pack up umbrella-shaped structure, in order to safely remove,
Reduce damage.
4th, catheter fixed mount: patent of the present invention provides a catheter fixator, uses duroplasts material, design height
Degree 20mm, is upper and lower two circuluses, and middle four column structures connect fixing, and upper strata ring design diameter and catheter are straight
Footpath is identical, rim openings, so that catheter snaps in wherein, and fixedly secures；Lower floor ring design diameter 30-40mm, rim openings,
Aperture position is identical with upper strata ring.Upper strata ring blocks catheter, and lower floor's ring is affixed on stomach wall, to reduce tractive.

Detailed description of the invention
When puncturing use, find bladder location, position suitable point of puncture, after local anaesthesia success, after puncturing out urine, remove pin
Cylinder, lower pressure puncture needle tail end cap-like structure, in making nook closing member, two finer wire head end folds are released in bladder, clog pin with cap stopper
Hole, prevents urine leakage；Cut skin length about 8mm with knife blade, by the expansion with self-tapping type not damaged safety screw
Pipe box is inserted in puncture needle, expands muscular fascia tissue；After expansion completes, double-jacket tube formula catheter is inserted in puncture needle, utilizes spiral shell
Line extruding release urinary catheter front end Anti-extrusion umbrella-shaped structure, finally extracts puncture needle, fixes catheter in abdomen with catheter fixed mount
Wall, end of operation.The Anti-extrusion puncture needle that patent of the present invention provides can reduce to surrounding tissue particularly intestinal tube and blood vessel
Accessory injury, and do not fall out after urinary urine bladder liquid flow goes out and cause puncture failure, reduce the generation of complication, improve result for the treatment of.
The double-jacket tube formula umbrella that patent of the present invention provides without air sac urinary catheter, simple in construction, easy to use, be easy to fixing, to mucous membrane of urinary bladder
Stimulate little, the success rate of punctio vesicae can be greatly improved, reduce the misery brought to patient simultaneously.This fistula-building device is used to suffer from
The wound of person is little, recovers fast, simultaneously simple to operate, be easily mastered.Later stage changes catheter conveniently simultaneously.
