Abstract

The utility model discloses an anti-blocking and easy-inserting type three-cavity urinary catheterization device, comprising a urinary catheterization pipeline, a blood clot breaker and an inner core, wherein the blood clot breaker and the inner core are matched with the urinary catheterization pipeline; a spring steel wire is arranged in a wall of the urinary catheterization pipeline; a balloon is arranged in front of a water cavity; and an oval hole is arranged on a middle circular face of the balloon. The spring steel wire is arranged so that the thickness of a pipe wall of the urinary catheterization pipeline is reduced, an inner cavity of the urinary catheterization pipeline is expanded, the blocking is reduced, and the drainage is ensured to be smooth. The spring steel wire is elastic; the spring steel wire becomes small in insertion; the spring steel wire is expanded after being inserted; elastic fixation is generated between the spring steel wire and a urethra; a phenomenon of urine leakage is difficult to occur; the balloon is additionally arranged in front of the water cavity, and a drainage hole is arranged on the balloon; and when the drainage is unsmooth caused by the blocking of a blood clot, the blood clot breaker is used for breaking the blood clot to ensure the smooth drainage.

Description

Anti-blocking easily inserted three chamber o urethral catheterization devices

Technical field

This utility model belongs to medical instruments field, is specifically related to a kind of o urethral catheterization device.

Background technology

Existing catheter is made by macromolecular material, because macromolecular material matter is soft; In order to satisfy instructions for use, thicker the making of the tube wall of catheter, thus cause its inner chamber less; So be prone to when inserting produce the plugging phenomenon, when especially clot being arranged, be difficult for inserting bladder; The leakage of urine phenomenon also often takes place, or insert exceedingly difficult, make patient uncomfortable, feel bad.Mainly be because catheter itself lacks and the flexible fastening of urethra.

The utility model content

The purpose of this utility model is to provide that the broken clot of a kind of ability, drainage lumens are wide, warping resistance, be prone to insert, three chamber o urethral catheterization devices of urine.

This utility model comprises the urethral catheterization pipeline, with supporting clot destroyer and the inner core of urethral catheterization pipeline, passive spring steel wire is set in the wall of said urethral catheterization pipeline, and the urethral catheterization pipeline is provided with water cavity, and a sacculus is set in the front of said water cavity.

The end of said urethral catheterization pipeline is branched into four adapters: drain adapter, inner core are taken over and flushing is taken over and water cavity is taken over.

Said clot destroyer comprises the broken bar and the connection tube of front end band hairbrush, and broken bar passes connection tube.

Offer elliptical aperture on the middle anchor ring of said sacculus.

Said connection tube is the pipe that an end seals an end opening, and coupling is taken at its caliber and center, and its side is provided with interface.

The described o urethral catheterization device of this utility model with prior art elder generation ratio, has significant change: in the wall of urethral catheterization pipeline, be provided with passive spring steel wire on the structure; Thereby reduced the pipe thickness of catheter, under the condition of equal caliber, enlarged the inner chamber of catheter; Effectively reduced the catheter obstruction, guaranteed that drain is unobstructed, simultaneously because spring steel wire has elasticity; Be squeezed during insertion and diminish; Insert the expansion of rear spring steel wire, produce flexible fastening, be not prone to the phenomenon of leakage of urine with urethra; In the urethral catheterization pipeline, increased inner core, made the urethral catheterization pipeline insert easily, reduced damage to patient, brought convenience to the doctor, therapeutic effect is more reliable; Set up sacculus in the water cavity front, the conduction hole on the sacculus has increased, and has improved drainage speed; Increased the clot destroyer supporting with the urethral catheterization pipeline, running into has clot to stop up when making inadequate drainage, uses the clot destroyer to come broken clot, guarantees the smooth and easy of drain; The adapter that also has washed bladder.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this utility model comprises urethral catheterization pipeline 1, inner core 2 and clot destroyer 4 that passive spring steel wire 3 in urethral catheterization pipeline 1 wall, urethral catheterization pipeline 1 are supporting; Urethral catheterization pipeline 1 is provided with water cavity 11, and the front of water cavity 11 is provided with a sacculus 17, offers elliptical aperture 6 on the middle anchor ring of sacculus 17; The terminal bifurcated of urethral catheterization pipeline 1 is four adapters: drain adapter 12, inner core adapter 13 and flushing adapter 15 and water cavity take over 14.Clot destroyer 4 comprises the broken bar 41 and connection tube 42 of front end band hairbrush, and broken bar 41 passes connection tube 42, and connection tube 42 is the pipe that an end seals an end opening, and 12 couplings are taken in its caliber and drain, and its side is provided with interface 43.

During use; Earlier inner core 2 is inserted in the urethral catheterization pipeline 1 from inner core adapter 13, behind urethral catheterization pipeline 1 per urethra insertion bladder, pulls out inner core 2; From water cavity adapter 14, inject water with syringe to water cavity 11; Water cavity 11 expansions and bladder are fixed, taken over 12 end in drain and connect drainage bag, urine gets into urethral catheterization pipelines 1 drain success from conduction hole 6.

In the drain process, when not having the increase of urine in the sensation drainage bag, take drainage bag; Connect clot destroyer 4, bleed outward from interface 43, make to keep negative pressure in the urethral catheterization pipeline 1 with syringe 7; Twitch broken bar 41 broken clots up and down, and then connect drainage bag and can follow drain.

When needing washed bladder, from flushing adapter 15, inject flushing water, water flows into bladder from flushing hole 16.
