Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to one and can be used for ducts of prostate gland flushing, can be used for again the catheter of urethral catheterization operation.
Background technology
At present, prostatitis is treated in the world and the ruling by law of domestic employing prostate inner sealing, and conventional prostate irrigator has two classes:
1, prostate outer closure is adopted, two capsule four lumen and sengstaken-blakemore tube, adopt two large small water balloons, by clamping bladder internal orifice and the method for membranous part of urethra collar extension, form the enclosed space of bladder to membranous part of urethra collar extension, but due to the span of enclosed space too large, water pocket is fixing unstable, seal is poor, and especially intravesical water pocket is very easily passed by High-Pressure Water and retreated, and causes most of flushing liquor pouring intravesical instantaneously.
2, umbrella-shaped film occluder bladder mouth and prostate outlet in prostate is adopted.When the water entering prostate-urethra portion is more, admission velocity is faster, larger to umbrella-shaped film impulsive force, and umbrella-shaped film will be pressed on the mucosa wall of prostatic upper and lower mouth tightly, and by its tight closure, so the pressure produced is larger.By powerful fluid pressure, medicinal liquid is directly compressed in ducts of prostate gland.This process, in monitor screen, can clearly be seen: along with the pintle of the 20CC syringe filling medicinal liquid advances fast, unclamps fast, can see that whole body of prostate expands, reduces.This 20CC medicinal liquid can push repeatedly repeatedly, and anhydrous liquid enters bladder.Umbrella pipe prostate inner sealing pressurization dose regimen the most effectively treats chronic prostatitis method at present.Medicine by the high pressure in the generation of prostate-urethra portion, and is compressed in ducts of prostate gland by it, and direct bactericidal antiphlogistic, can cure chronic prostatitis average ten times.
Umbrella-shaped film prostate inner sealing pressure flush pipe disclosed in patent publication No. CN202637582U, the umbrella-shaped film prostate inner sealing pressure flush of employing, the flushing liquor of injection does not leak outside, and structure is simple, and therapeutic effect is good.But because umbrella-shaped film is little, do not hide opening of bladder completely, flushing liquor is outflowed, affects developing result; And adopting single hole water outlet, water hole is slightly large, and during high pressure beam, urethral catheterization body apopore place is weak, stays intraprostatic hidden danger after there is fracture.
Up to now, the o urethral catheterization device generally used is only a simple silica gel tube, and during use, per urethra inserts bladder, and intravesical urine is flowed out through catheter,
Summary of the invention
This utility model aims to provide a kind of employing umbrella-shaped film, porous water outlet, outer shroud enclosed construction, have flushing and the dual function of urethral catheterization concurrently, and the flushing liquor injected evenly, not leaks outside, eutherapeutic catheter.
For this reason, the technical solution that this utility model is taked is:
A kind of catheter with pre-washing function, comprise with rear portion transition conduit urethral catheterization body and be connected to the joint of transition conduit rear end, it is characterized in that, the front end of urethral catheterization body is inserted and secured in a little umbrella shape silicon rubber film headfirst, silicon rubber film major part can along the external wall slip of catheter, the first-class spacing of urethral catheterization body be inserted in silicon rubber film has at least 2 water holes, and water hole all interlinks with the endoporus of urethral catheterization body; Urethral catheterization body near silicon rubber film side is fixed with silicone rubber closed-loop, and the urethral catheterization tube wall subscript between silicone rubber closed-loop and transition conduit is marked with length scale.
Described silicone rubber closed-loop external diameter 0.6 ~ 1.0mm larger than catheter body diameter, silicone rubber closed-loop width is 3 ~ 5mm, and silicone rubber closed-loop is 30mm apart from the distance of silicon rubber film front end.
The aperture area summation in described water hole is 0.8 ~ 1.2 times of endoporus end area.
On described urethral catheterization tube wall, length scale starting point is 150mm apart from the distance of silicon rubber film front end, and scale range is 150 ~ 250mm.
Described joint is divided into water supply connector and water out adapter, with sealing ring on the endoporus of water supply connector; The endoporus of water out adapter is clear opening.
Described silicon rubber film major part is 1.2 ~ 1.5 times of urethral catheterization body diameter of bore along the distance of the external wall slip of catheter.
Using method of the present utility model and beneficial effect are:
When rinsing prostate, adopt water supply connector, with silicon rubber thin membrane closure bladder end opening, the silicone rubber closed-loop on urethral catheterization body can be formed with the membranous part of urethra and seal, the membranous part of urethra and bladder end opening two circular openings can be closed respectively, the confined space that formation one is short and small in prostate region.
Adopt the design in many water holes in silicon rubber film, make use of fluid mechanics principle, water velocity is faster, impact of water is larger, silicon rubber film expansion fuller, to circular port close tighter, thus, can form the higher pressure space of a sealing in atrium, flushing liquor can not flow into bladder, can Repeatable sequential action.
During pressurization, inside silicon rubber film, water hole makes silicon rubber film fully expand, and flushing liquor can not bleed bladder, and make prostate region field extension, orifice of prostatic duct is opened, and flushing liquor is directly rushed in ducts of prostate gland.When cancelling suddenly pressure, the body of prostate resilience of expansion, flushing liquor in atrium and glandular tube is squeezed again in re-injection emitter (general employing 20 milliliters of syringes), repeatable operation like this several times after, again the flushing liquor of muddiness is drained, separately renew liquid operation above-mentioned steps, can not pollute bladder.
This utility model overcomes the water outlet of prior art pressure flush pipe single hole, water hole is large, high pressure beam or when extracting umbrella-shaped film easily stay the hidden danger in prostate region, adopt many outlet hole structures, its area sum is identical with former single hole water-outlet area, flow, pressure are consistent, but current evenly, shock point increases, scattering surface is larger, effect is more abundant, and is easy to make, and application safety coefficient is high.
During urethral catheterization operation, replace with water out adapter, according to graduation indication, bladder depths is stretched in catheter front end, then insert the injection device with adjustable pressure and traffic engineering capability at water out adapter endoporus, in catheter body, inject water, regulate pressure to balance, make the intrinsic pressure power of urethral catheterization body be equal to or slightly greater than bladder pressure, now, silicon rubber film is floating to be opened, back moving urethral catheterization body makes silicon rubber film overturn, and pulling out injection device can carry out urethral catheterization operation.
This utility model is easy to make, easy and simple to handle, has flushing and the dual function of urethral catheterization concurrently, and the flushing liquor injected evenly, not leaks outside, and therapeutic effect is good, and safety coefficient is high.
