Description

The hollow body lavage

The present invention relates to the health lavage, such as wound/surgery lavage or a kind of hollow internal body organ, the lavage of patient's bladder particularly, and comprise conduit, the method and system that is used for this lavage, the lavage term is understood to include from the bladder of lavation and washes away chip.

Bladder wash away with lavation through being usually used in getting rid of the chip in the bladder so that improve produce this class chip, calculus forms and incrustive effect, they can both cause blocking.

Adopt catheterization when in handling a large amount of patients, urinating dysfunction.About 4% the public stands secular catheterization (LTC) and about 10% to nursing patient's burden owing to the patient and permits the catheter that patient in hospital will have insertion.The application of urethral catheterization is with different change of reason of short-term catheterization (STC), comprising drawing urine stream after the operation, monitor the urine output during acute disease and alleviating urine retention.LTC is that neurological disorder or bladder outlet take in when obstructed at the urinary incontinence of handling long-term urokinase dysfunction such as refractory.

With the LTC complications associated with arterial system be common, and comprise uncomfortable, infect, urine is sewed, wound and conduit stop up, crust and obstruction and calculus form.

Suprapubic catheterization has seemingly been improved some complication relevant with urethral catheterization, comprising infection.Produce problems such as chip, calculus formation and (conduit) crust,, all can cause stopping up in any case keep.The modal reason that conduit stops up is the generation of crust in catheter lumen.Crust and calculus are made up of many kinds of materials, comprising guanite; The wherein the heaviest main component of calculus is that (density is 2500kg/m to calcium phosphate ³).

Bladder washes away with lavation have been implemented, and particularly implements by catheter.Conduit washes away and normally comprises by the wash away solution of a conduit with prescribed volume and being transported in the bladder, and this conduit usually is connected to solution bag or scrubber, and the liquid that bladder is then extracted out perhaps allows solution and chip flow in the bag.The bladder lavation comprises simultaneously input and the discharge to bladder.In these two notions, (washing away and lavation) can have very large-scale flow velocity.Adopt lavage to believe it is after surgical operation at present, it cleans the lightweight debris in blood and the bladder.

When handling crust and stopping up, existing actual practice is to rely on bladder to wash away to a certain extent, also is appropriate by change conduits such as diet, fluid picked-ups perhaps.Use although regular bladder washes away by 40% LTC patient, have now found that this class is washed away the chip that can not get rid of effectively in the bladder.Surgery lavation under high flow velocities also is used for getting rid of chip from bladder, comprising little calculus, but calculus usually grows into a size, and this size calculus must be got rid of with splanchnoscopy or surgery formality.With use bladder to wash away relevant potential danger to comprise damage to mucous membrane of urinary bladder.

Therefore, the objective of the invention is to manage to reduce the above-mentioned shortcoming that has lavation now and wash away formality.

According to a first aspect of the present invention, provide a kind of conduit, be used for the organ of irrigating lavation boring, this conduit comprises that is used for a chamber and the chamber that is used for drawing from organ irrigating and chip that irrigating enters.

According to a second aspect of the present invention, provide a kind of method of lavation hollow internal body organ, this method may further comprise the steps: with the catheter introducer official; The far-end of conduit is positioned to apart from organ inner boundary wall one desirable distance; Allow the chamber of irrigating by entering organ from the irrigating source along conduit; With from bladder, draw irrigating and chip along another chamber.

Irrigating can enter organ under action of gravity.

Alternatively, irrigating can enter organ by suitable device such as pump.

According to a third aspect of the present invention, provide a kind of system that is used for the lavation hollow internal body organ, this system comprises a conduit and an irrigating source.

Fig. 3 (a)-6 (b) illustrates the

embodiment

30,40,50,60 of two chambeies or double channel catheter, and one of them supplies in the present invention, and uses according to the present invention.In Fig. 3 (a) and 3 (b), two chambeies the 2, the 3rd, co-axial, have import and outlet, this import and outlet form by the opening that cuts conduit.

In Fig. 4 (a) and 4 (b), bladder is led at far-end in chamber 2, so that an import (Fig. 4 (a)) or outlet (Fig. 4 (b)) are provided, and enter the chamber or the passage that comes out from the chamber is by isolated through hole 41, the axis of this through hole 41 meets at right angles with the longitudinal axis of conduit basically.

In Fig. 5 (a), 5 (b), 6 (a) and 6 (b), enter chamber 3 accordingly or 3 passages that come out are by through

hole

51,61 from the chamber, the longitudinal axis of this through

hole

51,61 and conduit 50 angle that tilts.The longitudinal axis of oblique angle and conduit is into about 60 °.In Fig. 4 (a) and 4 (b), the distance between the heart of hole ' S ' is 10mm.In an embodiment, length ' X ', Fig. 1 is 130mm.

Turn to Fig. 7,7 (a) and 7 (b) now, these illustrate simulation and implement bladder lavation of the present invention and wash away the experimental provision 70 of system.Spherical transparent flask 71 is represented bladder, so that the disturbance of the visual chip 4 of energy, the disturbance of chip 4 is shown in Figure 14.A device only is shown, but in experiment, adopts the flask 71 of two kinds of sizes, a kind of is the A type, and diameter is 80mm (the about 270ml of volume), and in Type B, the flask diameter is 60mm (the about 110ml of volume).In A type (shown in Fig. 7,7 (a) and 7 (b)), flask 71 has central authorities' mouthful 72 and two angles 73,74, and central authorities mouthfuls 72 are used for pipe 75, and simulation has the conduit in two chambeies, and angle one of them 74 clog.In the Type B (not shown), flask has only an angle except central authorities' mouth.

To the flask of two kinds of models, angle 73 is used to adorn the pressure transducer of calibrating 76 (piezometer of 0-0.35 crust), so that the bladder pressure of inside during the monitoring experiment.Therefore total arrangement is shown in Figure 7, concerning two kinds of flasks 71, uses tap water as liquid medium or irrigating, because the density of tap water (is 993kg/m down at 37 ℃ ³) with urine density (1016-1022kg/m ³) significantly not different.Pass irrigating tube 75 and be subjected to pressure head and reducer (adjustable constriction) control, and monitor with suitable effusion meter with the flow velocity that enters flask or bladder model 71.With standard lavation bag as the irrigating container.Utilizing the pressure head of about 1.6m water to obtain needed volume flow rate, is little therefore in the change of duration of test pressure head (approximately 60mm water) in proportion; This guarantees that at each duration of test flow velocity keeps substantial constant, remains within-3%.

Irrigating solution and any particle on the outflow side of irrigating tube, flow on a filter paper in one of them of three vacuum filtration funnels 77 (Fig. 7).All tests all are to carry out under room temperature (between 18 and 24 ℃).In some test, the flask immersion is equipped with in the rectangle lucite groove of water, so that eliminate optical distortion.

Tested the irrigating tube embodiment of Fig. 3 (a)-6 (b).All irrigating tubes comprise that all an internal diameter (i.d) is the rustless steel outer tube of 5.84mm and the interior pipe of coaxial rustless steel that i.d is 3.2mm, and outer tube and the two wall thickness of interior pipe are 0.5mm.Interior pipe and the "T"-shaped together end of outer tube soldering.Concerning each embodiment, interior effective (a) is used for flowing into ' I ' and (b) is used for outflow ' R '.As the test of control, be a kind of special use three road continuous lavation 20ch conduits (Rusch Simplastic) with polrvinyl chloride (PVC) system.With diameter is bead and the 2500kg/m of 0.212-0.300mm ³Density simulate the closely knit chip of hard in the bladder.Gathering system comprises 3 vacuum filtration funnels (shown in Figure 7), uses together with 1 grade of filter paper of Whatman (qualitative, middling speed) in order.

To each test, model bladder 71 is all filled water, adds the dried bead of 5g then.Then with lavation/flush pipe with model bladder is located on demand and directed.Irrigating solution flowing through under action of gravity opened the valve (not shown) and begun, and continues maximum 12 minutes.The stream ' R ' that goes out of model bladder 71 redirect to different filter funnels with 4 minutes interval.So that utilize all 3 containers in the duration of operation 12 minutes (maximum).

After each test, turned letter model bladder 71 and rough rinsing are so that remove all beades.From funnel, take out three filter paper, 150 ℃ of oven dry 30 minutes down, then measure lavation simultaneously, do bead quality (preliminary test shows, reaches constant weight in 30 minute drying time).

Carried out following experiment.

(i) carry out 12 minute persistent period test, so that be effective when determining the chip of which kind of tube designs in getting rid of bladder model A and B.Wherein each all keeps far-end or tip vertically apart from bladder model bottom 5mm for 5 lavation/flush pipes or conduit.

Then test, so that the following effect of research:

(ii) change and make the bottom of pipe tip near bladder.Distance in the research 5-10mm scope;

(iii) pipe is aimed at chip (Fig. 9) with an angle of attack (φ);

(iv) with bladder model and pipe tilting with vertical direction angled (θ) so that provide the synthetic angle (Fig. 7 (b)) of the angle of attack and offset angle; With

(V) different flow velocity.

[except as otherwise noted, otherwise the pipe of Fig. 3 (a) keeps vertical, and aims at chip in the distance of 5mm, flows with 150ml/min in the clock time from bladder model A with at 4 minutes].

Under the flow velocity that begins duration of test (at 150ml/min) on the pipe of Fig. 3 (a)-6 (b), carry out), find that the pressure in the bladder model is in～0.01 crust (1kpa) barometric pressure range; These pressure are too little certainly, so that can not carry out record in the test afterwards.Find that flow velocity change in the beginning process of the test can not surpass～3%; These variations are low qualifiedly certainly.

In test (i), compared the performance (Fig. 8,9,10 and 11) of different tube designs.Every kind of pipe is used for model A carries out twice test; Following pipe is reached considerable chip to be got rid of: 3 (a) [87%, 91%], 3 (b) [45%, 59%] and 4 (b) [13%, 12%].In all cases, to be excluded all be to take place in 4 minutes to the major part of chip; In (Fig. 8), the chip of removing is less than 5% to other pipes during twelve minutes test.Comparison shows that of the eliminating speed of model A and B, in the scope of being tested, bladder size seldom or not exerts an influence.

The eliminating speed that pipe reached of Fig. 3 (a), more much higher than the eliminating speed that other designing institute reaches, and more can reappear; Therefore the pipe of Fig. 3 (a) is only used in later test.

Test (ii) that the result shows,, then reach very high eliminating speed (behind the 4min about 80%), (Fig. 8) if pipe is in the 8mm scope of distance bladder model bottom.To distance greater than 8mm, get rid of efficient and sharply reduce, the distance of 10mm is dropped to be lower than 20%.Visualization and photography propose forcefully, chip is got rid of and the relation of distance is owing to the volume that local high detrital grain speed is arranged (" fluidization " zone) takes place, this local volume extends upward-and 8mm-is by the jet that flows into, (Figure 14) that bladder model wall and bead interact and cause, to Fig. 3 (a), 4 (a), 5 (a) and 6 (a) and to pipe 3 (b) and 4 (b), to observing fluidised granule zone, but do not occur with other pipe.Pipe 1 and 2 has the high speed of getting rid of, and the pipe that reaches 4 (b) is finished better than 4 (a), supports such view, and promptly having effuser in the fluidized grain zone is the key factor of efficiently getting rid of chip.Find that also chip is got rid of speed to angle [φ is in test (iii)] and accumulated angle and misalignment [φ is in testing (iv)], be used for respectively up to～25 ° and 20 ° all more insensitive (Figure 11 and 12).Should note, 20 ° of angle θ are equivalent to 14mm misalignment and additional vertical dimension apart from chip 2mm, therefore to θ＞20 ° chip get rid of efficient reduce may partly be because tilt and with the change of chip misalignment vertical dimension, rather than simply owing to tilt.

At last, the result of test (V) shows that along with flow velocity is increased to up to 150ml/min, the chip eliminating increases sharply; After this get rid of and be not subjected to speed (used maximum rate, Figure 13) influence of flow velocity basically up to 650ml/min.

Although flow velocity (150ml/min typically) used in each experiment is compared greatly with present flow velocity used in the lavation formality, but preliminary study shows, they wash away the Peak Flow Rate and the mean flow rate that occur usually in the process than bladder and (are respectively 1180 ± 250ml/min and 540 ± 200ml/min, meansigma methods ± standard deviation (SD)) much lower, these numerical value are at a ural.

On the effusion meter 8 objects are measured and write down.A situation arises carries 150ml/min down without any significant hydrostatic superpressure also to have it should be noted that to the design studies of irrigating tube the flowing of (pipe 1-4)-in bladder model.In addition, the upper limit can be set, and is set to normal stress (σ) to managing 1 (a), and this normal stress (σ) takes place on the bladder model bottom owing to the inflow jet of irrigating solution; To the flow velocity of 150ml/min, inequality σ＜0.5 ρ ²(ρ is the density of water herein, and V is the average speed in the inflow pipe) provides σ is 50Pa or still less.

Experiment shows, fluidization chip zone is near the place of one jet impulse bladder model bottom that enters irrigating, and when the outflow area of irrigating tube be within the fluidization zone time, produce very high chip eliminating speed (Figure 14).On the contrary, when effuser was not within the fluidization zone, chip was got rid of poor effect.Therefore concerning steady flow's chip washes away conduit, entrance cavity enters the import of the outlet of conduit and outlet plenum should be very approaching mutually.In addition, if the irrigating solution jet that enters is aimed at settled chip, then become angle should have the receptible high speed of getting rid of up to-25 ° with vertical direction.

In all embodiments, for the far-end that guarantees conduit 1 and the spaced apart optimum distance of wall of urinary bladder are used for lavation and wash away, so that outlet plenum is in " fluidization " chip 4, should produce thereon by the lavation impinging jet that enters by " fluidization " chip 4, the far-end of conduit can have an isolation apparatus or device, this device can be the extension of conduit self, it is for example by above-mentioned semi-circular portions being cut the sweep of formed end that this extension utilizes, a spacer that separates perhaps can be arranged, this spacer can be before lavation and flush operation begin movable being installed on the far-end.

In all experiments, the aforesaid operations formality is implemented under gravity is done.Yet, should be appreciated that, can replace only relying on gravity with suitable device such as pump.Plan can be used existing washing away/irrigation solution with wherein said conduit and/or system.

In addition, in all embodiments, should be appreciated that the diameter in each chamber is than reaching the degree of getting rid of chip the best from bladder that makes.

Should be appreciated that described with reference to the accompanying drawings the present invention can find other to use, for example clean some objects such as storage tank, swimming pool, liquid and its inside are housed relatively advance not go the bucket or the object that clean.
