Abstract

The utility model relates to an outward-turned urethral catheterization tube, which is composed of a urine tube cladding film, a urine tube head end, and convex and concave rings of the urine tube. During with the feeding of the outward-turned urine tube, at the beginning of the urine tube turnover, the first convex and concave ring can slowly overturn during the push-in of the urine tube, afterward, the convex and concave ring finished the overturn is immediately straightened, the diameter of which is enlarged to form an outer tube, and the non-turnover convex and concave ring becomes an inner tube; after the first ring overturn completed, the second ring continues to overturn under the pushing of the urine tube, and so on, and the rest of the convex and concave rings continuously complete the identical overturning process, until the urine liquid is guided out. Because of the interaction force between the overturned outer ring and the non-overturned inner ring, the friction force between the inner tube and the outer tube can be reduced during the pushing process, and the pain to the patient during inserting the tube and the possibility of bleeding caused by the injury to the prostate after the urine is guided out are considerably reduced. The urethral catheterization tube has the advantages of simple structure, low cost, and easy operation and learn.

Description

The eversion type catheter

Technical field

This utility model relates to a kind of medical apparatus and instruments eversion type catheter, is a kind of catheter that has relative no Frotteurism between catheter and the urethra that forms in urethral catheterization intubate process.

Background technology

At present, hospital carries out the mode that the urethral catheterization employing is directly gone into the catheter straight cutting for the patient, and in urethral catheterization intubate process, friction is bigger between catheter and the urethra, be easy to damage urethra, cause after patient's pain discomfort and the urethral catheterization bigger the hemorrhage probability of male's injury of prostate.At the problem that exists, this utility model provides a kind of novel eversion type catheter.This catheter can form in urethral catheterization intubate process and have relative no Frotteurism between catheter and the urethra.And can obviously be reduced in the urethral catheterization intubate process after the patient's pain discomfort and urethral catheterization the hemorrhage incidence rate of male's injury of prostate.

Summary of the invention

Be this utility model order, a kind of novel eversion type catheter is provided.This catheter is made up of urinary catheter peplos, urinary catheter head end, the concavo-convex ring of urinary catheter; Adopt the eversion type catheter when inlet pipe, originally catheter overturns, and first concavo-convex ring is slowly finished upset under the propulsive effect of urinary catheter, and the concavo-convex ring of finishing upset becomes straight immediately, it is big that diameter becomes, form outer tube, and unturned concavo-convex annular becomes interior pipe, after first concavo-convex ring has been finished upset, second concavo-convex ring continues to finish upset under the propulsive effect of urinary catheter, the rest may be inferred, and follow-up each concavo-convex ring continues to finish identical switching process, up to deriving urine.Because the concavo-convex ring of outer tube is when turning up, concavo-convex ring becomes straight, it is big that diameter becomes, and the concavo-convex ring of interior pipe becomes more recessed, diameter diminishes, and the elastic reaction of conduit self changes the size of caliber, outer tube rotates displacement gradually, the concavo-convex ring of inner and outer pipes is embedding mutually mutually, pressure between the inner and outer pipes is diminished, the frictional force of inner and outer pipes also diminishes, and more helps intubate, and can obviously be reduced in the urethral catheterization intubate process after the patient's pain discomfort and urethral catheterization the hemorrhage incidence rate of male's injury of prostate.This catheter is simple in structure, and is cheap, easy to operate easy grasp.

Eversion type catheter described in the utility model, this catheter is made up of urinary catheter peplos, urinary catheter head end, the concavo-convex ring of urinary catheter, urinary catheter head end (2), urinary catheter peplos (1) and urinary catheter recessed (3), bulge loop (4) are connected as a single entity, one end of urinary catheter head end (2) is urinary catheter peplos (1), and the other end of urinary catheter head end (2) is continuously wavy recessed (3), protruding (4) circulus.

Be marked with scale at urinary catheter recessed (3), protruding (4) ring wall.

End at urinary catheter recessed (3), protruding (4) ring is urinal band interface commonly used.

This catheter is made by silica gel or latex or flexible material.

This catheter can be made into various different sizes, to be adapted to the patient of various age brackets.

The specific embodiment

Further describe and provide embodiment below in conjunction with accompanying drawing

Eversion type catheter described in the utility model, this catheter is made up of urinary catheter peplos, urinary catheter head end, the concavo-convex ring of urinary catheter; Urinary catheter head end (2), urinary catheter peplos (1) and urinary catheter recessed (3), bulge loop (4) are connected as a single entity, and an end of urinary catheter head end (2) is urinary catheter peplos (1), and the other end of urinary catheter head end (2) is continuously wavy recessed (3), protruding (4) circulus; Be marked with scale at urinary catheter recessed (3), protruding (4) ring wall; End at urinary catheter recessed (3), protruding (4) ring is urinal band interface commonly used; This catheter is made by silica gel or latex or flexible material; This catheter can be made into various different sizes, to be adapted to the patient of various age brackets.In use, the head end of catheter inserts urethral orifice, left hand is fixed on urinary catheter peplos (1) around the urethral orifice, urinary catheter head end (2) docks in urethral orifice, the right hand inserts urethra with catheter and advances, first recessed (3), slowly finish upset under the effect of protruding (4) ring and urinary catheter propulsive force fixing at urinary catheter peplos (1), finish recessed (3) after the upset, it is straight that protruding (4) ring becomes immediately, it is big that diameter becomes, with unturned recessed (3), protruding (4) ring has formed the inner and outer pipes structure, promptly finish recessed (3) of upset, protruding (4) ring is outer tube, unturned recessed (3), protruding (4) ring is interior pipe, and the outer tube after the upset is straight owing to concavo-convex ring becomes, and it is big that diameter becomes, played fixation, and pipe is under the effect that continues propulsive force in unturned, and second concavo-convex ring continues slowly to finish switching process, and the rest may be inferred, follow-up each concavo-convex ring continues to finish identical switching process, up to deriving urine.Be marked with scale at urinary catheter recessed (3), protruding (4) ring wall, can observe the degree of depth of inserting conduit in operation; End at urinary catheter recessed (3), protruding (4) ring is a urinal band interface commonly used, common urinal is directly overlapped incoming interface get final product.This catheter is made by silica gel or latex or flexible material.

The concavo-convex ring of outer tube after the upset and unturned in have the effect of mutual power between the concavo-convex ring of pipe, make that the outer tube diameter after the upset becomes big, this is because urethra and inboard circulus to its dual effect, make that the concavo-convex ring structure on the outer tube becomes straight.And in unturned the diameter of pipe to diminish be because the concavo-convex ring structure on the interior pipe becomes more recessed.Scribble paraffin oil between outer tube after the upset and the unturned interior pipe, the frictional force of pipe in progradation and between the outer tube in can reducing obviously is reduced in the urethral catheterization intubate process after the patient's pain discomfort and urethral catheterization the hemorrhage incidence rate of male's injury of prostate.This catheter can be made into various different sizes, to be adapted to the patient of various age brackets.
