Description
Technical field
The present invention relates to the system of a kind of flushing and discharge, collection organization and be used for the treatment of the method for process.
Background technology
A lot of therapys all relate to the flushing body cavity.For instance, must washed bladder in the urology department therapeutic process of many uses endoscope to wash away similar matter such as (and collecting in some cases) blood clot, fragment of tissue.Usually used method is that aseptic salt solution or water are introduced bladder, extracts out then and contains the fluid that will remove material that mixes and suspend.This process need repeats no longer to contain particulate matter clearly and satisfactorily until the fluid change of extracting out.
At present, the modal device that is used for bladder irrigation is the Ellik aspirator, and it comprises transparent hourglass shape bowl bodies, has the ball and the nozzle that are installed to the bowl body, can make solution by urethra and bladder circulation.Ball is opaque and meets at right angles with the hourglass axis.Therefore, the Ellik aspirator problem is to be difficult to fluid filling and to remove air.It is desirable to, the tissue collecting in reflux solution is to lower chambers.Because the action of gravity tissue accumulates in lower chambers.Therefore, another restriction of Ellik aspirator is that the tissue of carrying secretly must arrive lower chambers by gravitational settling.As a result, granule and the tissue that has only proportion to surpass sterile solution can be deposited in lower chambers., the granule that is suspended in the upper chamber often can enter bladder again when pushing the suction ball once more.In addition, irrelevant with proportion, tissue or particulate matter usually are inhaled in the ball, and because ball is opaque, and the tissue of staying the there can not be seen and may lose.In order to prevent foul solution that first flushing produces again by the circulation of Ellik aspirator, the surgeon must empty repeatedly and again filling Ellik aspirator can keep limpid until final rinse solution.Repeat the work except that this, empty and filling Ellik aspirator more at every turn, also must manual filtration when accumulating in being organized in flushing and finishing in the flushing liquor and they are taken out from groove.In this process, sometimes tissue can drop on desktop or the floor, thereby the operation room work personnel exist the very big contact blood and the danger of tissue.Last problem of Ellik aspirator is that ball is filled in the slick glass mouth of pipe as stopper.Because ball neck is level and smooth and is cylindrical shape, so have only the frictional force of no mechanical benefit to hold them in together.Therefore, if do not note being easy to make ball and glass container to separate in operating process, the result is that glass container drops on the floor and smashes.
Having done a lot of trials wishes the Ellik aspirator is improved.These achievements in research comprise U.S. Patent No. 3,892,226; 4,282,873; 4,729,764; 4,801,292; 5,338,294 and 5,421,824 devices of being introduced.Except the special limitation of himself, all devices of introducing in these patents all can not reach the desired level and the speed of Ellik aspirator institute turbulization.And, there is not the mechanism of tissue collecting that can shift easily in these devices.For instance, in U.S. Patent No. 5,421, in 824, the crimping section of container forces fluid to enter body cavity from container, makes the extrusion demi-inflation extract fluid out by discharging extruding force then.Regrettably, by the turbulent flow that this extrusion part produces, particularly the negative pressure that produces when the release extruding force is not enough, thereby less than the negative pressure of Ellik aspirator.And container and top cover joint often have fluid leaks.In addition, though this patented technology can prevent grain structure and enter body cavity again, therefore but the mechanism of tissue collecting that does not have easy transfer is subjected to and the same circumscribed puzzlement of Ellik aspirator, because tissue that must manual defecator collection when flushing finishes and they are taken out from groove.In this process, sometimes tissue can be lost on desktop and floor, thereby the operation room work personnel operate the very big contact blood and the danger of tissue in this way.
Therefore, need a kind of flushing that has improved and tissue and discharge gathering system.
Summary of the invention
The present invention relates to a kind of medical flushing and tissue collection system, can fluid be introduced body cavity and extract fluid out from body cavity by fluid circuit.This system comprises: inside holds fluidic container; The pumper ball that is communicated with fluid container, available method except that pure friction connects securely; Pipe, first end links to each other with fluid circuit, the second end and internal tank fluid communication; With the catcher of collecting particulate matter.Catcher is positioned at internal tank and removably is connected the second end of fluid circuit.Catcher is provided with many perforates, allows liquid and passes through less than the particulate matter of preliminary dimension.
In one embodiment, the second end has porous part, has many apertures, allows the particulate matter of liquid and intended size to pass through.The relative size of aperture and perforate can be selected as required.For instance, the average-size of perforate can be greater than the average-size of aperture.Therefore, compare with the second end by pipe, less and middle-sized granule is more prone to free in and out catcher, makes the granule of large-size can collect catcher.

The specific embodiment
The invention provides a kind of flushing and collect the system and method for patient's body lumen inner tissue.This system comprises flushing and the gathering-device that flushing liquor is ejected into body cavity.Flusher is ejected into body cavity with flushing liquor from device by produce malleation in device.By the negative pressure that produces in installing flushing liquor is discharged from body cavity, thereby flushing liquor and any loose tissue or particulate matter are drawn in the device.Tissue and particulate matter that filtration and washing liquid will be discharged are collected in the catcher.
Repeat this process, the malleation that produces in the device is ejected into flushing liquor the body cavity from device.When jet douche liquid, previous tissue and the particulate matter of collecting is retained in the catcher, therefore can not reenter body cavity with the flushing liquor of ejection.The negative pressure that produces in the device makes flushing liquor discharge from body cavity once more, thereby flushing liquor and any loose tissue or particulate matter are drawn in the device.Filtration and washing liquid is collected catcher with the tissue and the particulate matter of more discharges.This process can repeat as required, and nearly all loose tissue and particulate matter are removed from body cavity.
With reference now to accompanying drawing,, wherein identical parts represent that with identical reference number Fig. 1 and 2 shows flushing of the present invention and tissue is discharged gathering system 10.This flushing and tissue are discharged gathering system 10 and are comprised the container 12 that holds flushing liquor.Flushing liquor can be the liquid of any flushing or lavation, as sterile physiological saline solution or aseptic aqueous solution.Pumper ball 14 is connected to container 12 by pump purt pipe 16.Though the purt of pump shown in accompanying drawing pipe 16 is installed in container 12, also pump purt pipe 16 can be connected dismountable top cover 18.Top cover 18 shown in the figure is threaded on the container 12, also can use other coupling mechanism.
During use, collecting bag 22 is arranged on container 12 inside, is used for obtaining the sample of particulate matter.Collecting bag 22 is provided with many perforates, allows the particulate matter of liquid and intended size to pass through.The particulate matter that the size of these perforates of collecting bag 22 can limit preliminary dimension flows through.Because collecting bag 22 can be made with net class material, such as netted woven bag, so different collecting bags can have various mesh size, to adapt to concrete application.For instance, if want to collect big tissue particles, can use the collecting bag that has than the large-mesh size.And, can also use serial collecting bag 22, so just can obtain the particulate sample of different size.
When making collecting bag 22, the size and dimension of perforate might not be uniform.This may cause perforate to have many shapes and certain size range (such as the sectional area of perforate).Therefore according in the art convention, the perforate of collecting bag 22 can think to have certain average-size.
Pipe 20 also comprises filter 28, such as porous part, allows liquid but does not allow particulate matter inflow and outflow container 12.Filter 28 is provided with many apertures, allows the particulate matter of liquid and intended size to pass through.The particulate matter that the size of these apertures of filter 28 can limit preliminary dimension flows through.Similar with collecting bag 22, when making filter 28, the size and dimension of aperture might not be uniform.This may cause aperture to have many shapes and certain size range (such as the cross-sectional area of aperture).Therefore according in the art convention, the aperture in the filter 28 can think to have certain average-size.
The relative size of perforate (collecting bag 22) and aperture (filter 28) can be adjusted according to concrete clinical setting needs.Such as, the average-size of filter 28 apertures can be less than the average-size of collecting bag 22 perforates.Like this, and compare by filter 28, less and middle-sized granule can more freely pass in and out collecting bag 22, the granule of large-size can be collected in the collecting bag 22.
Second end of pipe 20 ends at current limiter 26, and current limiter allows fluid (comprising any particulate matter) to enter in the collecting bag 22, but does not allow it to be back in the pipe 20.Current limiter 26 can be a valve, such as check-valves.Operable another kind of current limiter is one section flexible pipe of Penrose discharging tube or other type.Though check-valves can prevent fluid more effectively and flow out from collecting bag 22, be to use one section flexible pipe may be more effective, because there is not movable part and more economically in the flexible pipe.
Referring to Fig. 3, pipe 20 comprises flexible pipe part 29.When producing malleation from container 12 jet douche liquid in the container 12 (such as by extruding pumper ball 14), produce pressure reduction between the flushing liquor of flushing liquor in the flexible pipe part 29 and encirclement flexible pipe part 29.The pressure of flushing liquor that surrounds flexible pipe part 29 causes flexible pipe part 29 to become flat greater than the pressure of flushing liquors in the flexible pipe part 29, seals collecting bag 22 effectively and the tissue and the particulate matter that prevent to collect reenter body cavity with the recirculation flushing liquor.Flexible pipe part 29 can be provided with joint-cutting is more prone to the unlatching of tube chamber and closure.
When the extruding force on the pumper ball 14 is removed, can produce negative pressure, thereby fluid is drawn into the container 12 from body cavity by pipe 20.By pipe 20 flushing liquor is drawn into container 12 and can between the flushing liquor of flushing liquor in the flexible pipe part 29 and encirclement flexible pipe part 29, produces pressure reduction.The pressure of flushing liquor causes flexible pipe part 29 to expand greater than the pressure of the flushing liquor that surrounds flexible pipe part 29 in the flexible pipe part 29, is formed up to the path of collecting bag 22, collects and separate the tissue and the particulate matter of discharge from flushing liquor.
Collecting bag 22 of the present invention also can be made (perhaps as flexible pipe substitute partly) with flexible material.During from container 12 jet douche liquid, produce pressure reduction between the flushing liquor of the flushing liquor in the collecting bag 22 and encirclement collecting bag 22 when producing the malleation shown in arrow among Fig. 5.The pressure of the flushing liquor of encirclement collecting bag 22 causes collecting bag 22 self inwardly to become flat, thereby prevents that collected tissue and particulate matter 25 from reentering body cavity greater than the pressure of flushing liquors in the collecting bag 22.
When the extruding force on the pumper ball 14 is removed, can produce negative pressure, thereby fluid is drawn in the collecting bag 22, shown in the arrow among Fig. 4 by pipe 20.Flushing liquor is drawn in the collecting bag 22 and can produces pressure reduction between the flushing liquor of flushing liquor in the collecting bag 22 and the soft collecting bag 22 of encirclement.The pressure of flushing liquors is greater than the pressure of the flushing liquor that surrounds collecting bag 22 in the collecting bag 22, causes collecting bag 22 to expand and is formed up to the path of collecting bag 22, collects and separates the tissue and the particulate matter 25 of discharge from flushing liquor.
In use, system 10 becomes flushing and the tissue discharge gathering system that is used for any body cavity such as bladder.Can fill flushing liquor at container 12, then with the air purge of whole system.As well-known in the art, remove and to push pumper ball then repeatedly in the groove that air can sink to filled with fluid by the device that will open and realize, perhaps can be repeatedly the nozzle of locking device immersed flushing liquor and with the pumper ball suction until full of liquid.Can fluid circuit (being connected on the pipe 20) be advanced in the body cavity for the treatment of with endoscope.
By extruding pumper ball 14, force flushing liquor in the container 12 to pass filter 28 and discharge from pipe 20, pipe 20 is connected to body cavity by fluid circuit.When discharging the pressure of pumper ball 14, fluid is extracted out from body cavity by fluid circuit and pipe 20.Grain structure and other material are trapped in the collecting bag 22, and fluidic remainder will be full of container 12 and pumper ball 14 once more.When needing, collecting bag 22 can be thrown off and puts in the sample tanks.In this way, can accurately collect and submit independent sample and can not produce tissue and lose or mix.In this respect, container 12 or its part can be transparent or semitransparent, make it possible to the naked eye check fluidic turbidity.
