Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing and specific embodiment party
Present invention is further described in detail for formula.
Term is explained
In the present invention, following term or the meaning of describing mode are as follows:
The case where description of " A and/or B " indicates any of them or two kinds simultaneously may all occur, that is, include " A and
B ", " A ", " B " three kinds of situations.
The description of " A is essentially B ", " A is about B ", " A entirety B " indicates that A sees the B condition that meets, but and B on the whole
Between there may be certain difference again, and the difference is very little in the scale of B.

" reducer pipe " refers to internal diameter along its length and outer diameter gradually changed pipe.
In attached drawing of the present invention, quantity, size, dimension scale, relative positional relationship of each device etc. are only exemplary
Expression, rather than the restriction to corresponding device specific structure.
Carrier member
As shown in Fig. 2 to Figure 10, the embodiment of the present invention provides a kind of carrier member 1；The carrier member 1 is clear for being located at scope
It washes in circuit, and there is loading end 11, be attached with simulation dirt on loading end 11, the structure of carrier member 1 at least can make to flow through to hold
The fluid of section 11 generates turbulent flow.
When cleaning to scope 9, carrier member 1 is located in endoscope cleaning circuit, and cleaning solution flows through carrier member
1.Moreover, carrier member 1 can make the fluid for flowing through loading end 11 generate turbulent flow, that is, make the stream for flowing through the cleaning solution of loading end 11
Dynamic situation is similar to the flow condition for flowing through the cleaning solution inside scope 9, forms " challenge mode (Challenge) ".Therefore, if
Simulation dirt on loading end 11 is cleaned, then scope 9 is inevitable is also cleaned, and thus uses the carrier member
1 can carry out reliable and accurate detection to scope cleaning effect.
Preferably, a kind of mode as embodiment of the invention, the above simulation dirt include atriphos (ATP,
Adenosine triphosphate), i.e., it include atriphos ingredient in simulation dirt.
That is, the simulation dirt containing atriphos ingredient can be used.Specifically, atriphos can be dissolved
In solution (such as using polyvinyl alcohol as the atriphos solution of 1 mcg/ml of solvent), it is coated on loading end 11 later
On, the simulation dirt including atriphos can be formed on loading end 11 after solution is dry.
Be using the advantages of simulation dirt containing atriphos ingredient: one side atriphos has and scope
The similar adhesive ability of conventional dirt (such as bacterium, human secretion etc.) in 9, therefore endoscope cleaning effect is judged with it
It is accurate to compare；On the other hand, atriphos belongs to biomolecule, rather than bacterium, can pass through existing fluorescence detection
Directly progress is simple, rapidly detects, and does not have to be cultivated in advance, therefore its detection real-time is good, and time-consuming short, operation is simple
It is single.Wherein, fluorescence detection using fluorescein and luciferase reacts sending fluorescence with atriphos (wavelength about 550nm is extremely
620nm), and by analysis of fluorescence intensity confirm the amount of atriphos；Specifically, fluorescence detection can using existing equipment into
Row, such as use 3M Clean-Trace ATP fluorescence detector (being purchased from 3M company, Sao Paulo, the Minnesota State, the U.S.).
Due to the operation of the simulation dirt formed above including atriphos ingredient, and atriphos is examined
The specific method of the operation of survey is known, therefore is not described in detail herein, can refer to US2015257844A1,
The patents such as US2014099233A1, WO2014058652A2.
Preferably, another way as embodiment of the invention, simulation dirt may also comprise other biomolecule,
Specific available biomolecule includes but is not limited to alkaloid, nucleotide, protein (such as hemoglobin), nucleic acid, carbon aquation
Close object, enzyme etc., also include certainly more than atriphos.These biomolecule can also by existing method realize quickly,
Accurate detection is not described in detail herein.
Certainly, if using microorganism (such as bacterium) as simulation dirt and feasible.
Preferably, simulation dirt can also be macroscopic simulation dirt；More specifically, it may include coloured for simulating in dirt
Dyestuff.
That is, it is possible to use the substance that can be visually immediately seen is as simulation dirt, so as to straight by naked eyes
Judgement wash result is connect, and does not have to reuse other equipment.For example, simulation dirt can be for inherently with the object of obvious color
Matter, alternatively, colored dyes etc. can also be added into the simulation dirt for being difficult to visually see originally.Wherein, specific available naked eyes
Visible simulation dirt includes but is not limited to colored ink, animal blood, soy sauce, catsup etc..
Wherein, it is preferred that the loading end 11 of carrier member 1 is the face with the structure that can form challenge mode to cleaning.
That is, the loading end 11 can have specific structure, which can make the simulation dirt ratio on loading end 11
Dirt in scope 9 is more difficult to be cleaned out, and challenge mode can be formed to cleaning.
Specifically, a kind of mode as the present embodiment, the loading end 11 of carrier member 1 is rough surface.
That is, the above loading end 11 can have a large amount of minute protrusions, recess etc., so that its surface becomes coarse.
Obviously, the time that carrier member 1 is cleaned at least should be with time that scope 9 is cleaned quite (or also more than it
It is long)；Meanwhile the pollution level of the scope 9 of different application environment is different, therefore its practical time being cleaned is also different.Cause
