In some concrete embodiments, electronic installation 200 can comprise and collecting part 100 electrodes in contact 201 and processor 202, and the signal electron element 203 and power supply 204 that are connected with processor 202.These assemblies can connect through conductor or semiconductor, can make things convenient for the transmission of electronic signal between each assembly.In processor 200, can write the program software and the program circuit that write in advance and control processing and response each element signal.For example; When collecting fluid sample with collecting part 100, when collecting part 100 was collected a certain amount of fluid sample, the electrode 201 that is connected with collecting part 100 contacted with fluid; Electrode 201 conductings produce loop current; An electronic signal is accepted and sent to electric current by processor 202, and this electronic signal can let signal electron element 203, and for example signal lamp produces identification signal; For example light or sound, this light or auditory tone cues fluid sample are enough or reached predefined amount.In a preferred mode, be at least 2 with collecting part 100 electrodes in contact 201, in the starting stage, between two electrodes 201, apply a voltage; After two electrodes 201 are by fluid communication; Constituted current path; This current path is processed device 202 and receives electronic signal of back generation, and this electronic signal lets light-emitting component 203 send identification signal, and the expression fluid sample enough perhaps has been full of collecting part 100.Signal electron element 203 can pass through conductor, and for example electric wire is connected with processor 202; Electrode 201 also can be connected with processor 202 through conductor.In the embodiment of the utility model, electrode 201 directly integrates with processor 202.

The collected sample of collecting part that how much is meant of control that the utility model is alleged or adjusting sample collection amount satisfies the requirement that is provided with in advance; For example satisfy certain and chemically examine minimum or the highest needed volume or weight requirement, for example 0.5 milliliter, 0.7 milliliter, 1 milliliter, 5 milliliters or 1-10 milliliter.The sample size that sets can represent that whole collecting parts is full of fluid sample, can represent that also collecting part partly is full of by fluid sample.In the process of collecting sample, when sending the enough information of sample can realize light-emitting component prompting (like lumination of light emitting diode) through electrode conduction.Further,, also can make the conducting of electrode 201 accelerate or slow down through the size of regulation voltage (power supply) 204, thus the collecting amount of control and regulated fluid sample how much.Perhaps, regulate the size of resistance value, again or at electrode tip resistance in series R1 (205), both regulated the sensitivity of electrode, speed that also can the control electrode conducting, thereby what of the collecting amount of control fluid sample.Have again, when collecting different samples, can set what of collecting amount that different voltages with different and/or resistance value are controlled this sample according to different sample resistances.

Electronic installation can include only some electrodes 201, and power supply 204 (like button cell) of connecting with electrode and light-emitting component 203 (for example light emitting diode).After collecting part 100 was collected fluid sample, fluid sample contacted with the electrode 201 of electronic installation, and at this moment, electronic installation 200 is started working, and forms basic circuit as shown in Figure 2.In Fig. 2, during not conducting, being equivalent between two electrodes is an infinitely-great resistance between the electrode 201; And at fluid sample with after electrode 201 contacts; Because there is potential difference (PD) in the existence of supply voltage 204 between the electrode 201, this potential difference (PD) can make the electron ion in the fluid sample to electronegative potential (another electrode) electronics take place by noble potential (electrode) and move; Can reduce the resistance between the electrode gradually, so be equivalent to a transformable resistance R between the electrode 201; The voltage that power supply 204 provides is V; After the electrode in the electronic installation 200 201 touched fluid sample, the potential difference (PD) because of existing between the electrode 201 made the electronics of fluid sample move to low level from a high position; Finally make electrode 201 conductings to form current return, as shown in Figure 2; The electric current I circulation, also conducting of light emitting diode 203.Light emitting diode 203 after the conducting emits beam.After the operator receives light, promptly can stop to collect sample; Also promptly the sample size that needs is collected in expression.

At this moment, the basic functional principle of electronic installation 200 is formula (1):

I＝V/R

V is the voltage that power supply 204 provides, and R is the resistance value that forms between two or per two electrodes 201.

When the I value reaches the conducting electric current of light-emitting component 203 (light emitting diode), then light-emitting component 203 (light emitting diode) conducting.

After two electrodes 201 were by fluid communication, this path had electric current I to pass through, and it is enough that light-emitting component 203 sends the amount of the liquid that light representations collects; If opposite light-emitting component 203 does not send light, then enough liquid samples have not also been collected in expression.

Further; Under the given constant situation of the signal conduction electric current I that needs reach; Also promptly in order to guarantee that light emitting diode 203 can be luminous, when power supply 204 voltages changed, then the resistance R between the electrode 201 also needed to change thereupon; According to formula (1), the resistance of electrode 201 and power supply 204 voltages are proportional.In the utility model, this relation can be used for controlling and regulate collecting part 100 and collects what of sample sizes.When power supply 204 voltage decreases, then the resistance between the electrode 201 also needs corresponding diminishing just can reach given current value I.Like this, need more sample electronics (electric charge) that electrode 201 resistance are reduced, therefore, between two or per two electrodes, need the more fluid sample to reach this requirement, promptly collecting part 100 needs to collect the more fluid samples.Otherwise when power supply 204 voltages increased, the resistance value of electrode 201 also should correspondingly increase, and then had less sample electronics can make electrode 201 conductings between two electrodes; Therefore after collecting less fluid sample, circuit can form the current value I that makes light-emitting component 203 (light emitting diode) conducting.So, how much being inversely proportional to of power supply 204 voltages and sample collection amount.

In another preferred embodiment, what of sample collection amount electronic installation 200 also can control through regulating resistance.The mode of regulating resistance is not limited on electrode, increase an adjustable resistance, as long as the resistance value of entire circuit is changed.Among one embodiment, the function that can realize regulating resistance through the resistance value of regulating light-emitting component.

In another preferred embodiment, resistance in series R1 (205) on the electrode 201, its fundamental diagram is as shown in Figure 3.At this moment, the principle of work of electronic installation 200 is formula (2):

I＝V/(R+R1)

V is a supply voltage, and R is the resistance value that forms between two or per two electrodes, and R1 is for regulating the resistance of resistance R 1 (205).

When the electric current I value reaches the conducting electric current of light-emitting component 203 (light emitting diode), then light-emitting component 203 (light emitting diode) conducting.

In the time will reaching the electric current I of light-emitting component 203 conductings (even the luminous minimum current value of light-emitting component), under the constant situation of power supply 204 voltages, i.e. V; I is fixedly the time; According to formula (2), when regulating resistance R 1 (205) increase, electrode 201 resistance R just need reduce accordingly; Otherwise when adjusting resistance R 1 (205) reduces, electrode 201 resistance R will increase.Therefore, can control what of sample collection amount through adjusting resistance R 1 value that adjusting increases newly.After increasing adjusting resistance R 1 (205), need more sample electronics (electric charge) that electrode resistance R is reduced, this sample electronics is increased thereby need to collect the more fluid sample.Opposite, according to formula (2), when adjusting resistance R 1 (205) reduced, electrode resistance R then needed to increase, and therefore, collects less fluid sample, can make electrode 205 conductings.Therefore, regulate the resistance of resistance R 1 (205) and how much being directly proportional of sample collection amount.

Generally; Conductor electrode 201 sensitivity are higher, when touching fluid sample, and very easily conducting of electrode 201; After particularly collecting part 100 receives the pressure of part from sampling place when collecting sample (when collecting saliva sample; Collecting part pressure can be given in the oral cavity), electrode 201 conducting after collecting certain sample, thus light emitting diode 203 lamps are bright.But sometimes after collecting part 100 leaves sampling place; Pressure disappears; When concentrating near the electrode 201 samples originally and possibly have other positions, particularly collecting part 100 that part is distributed to collecting part 100 and be not full of by sample, this situation takes place more easily.At this moment, electrode 201 might cause reflective diode 203 to extinguish because of the not conducting again of sample size deficiency.The sample size that can cause like this collecting how much becomes uncertain or the sample collection amount does not reach predetermined requirement.Therefore, regulate resistance R 1 (205) and also have another effect, even the sensitivity of electrode 201 is lowered.Owing to form infinitely-great resistance R between the electrode 201; Behind the contacting with fluid sample, the resistance R that electrode is 203 constantly reduces, and electrode 201 is switched on; After the adjusting resistance R 1 (205) of the certain resistance of series connection; The circuit total resistance value increases, and electrode 201 is switched on not too easily, and electrode 201 stability increase.In the specific embodiment, this resistance of regulating resistance R 1 (205) more than or equal to 1Mohm after, can effectively increase the stability of electrode 201.

Following table 1 for the resistance of the adjusting resistance R 1 (205) that increases under different resistances, when gathering-device 700 is collected samples, light emitting diode 203 luminous and the data plot that extinguishes.(every group is adopted 5 samples)

Certainly; Resistance R 1 (205) value is big during to certain value when regulating, when sample is full of collecting part 100, promptly during R value infinitely small (R at time be the resistance value of sample); Circuit also can not form current return too greatly because of the R1 value, thereby light emitting diode 203 can be not luminous.Like this, this gathering-device 700 just can't be realized it and collect the function of prompting.Therefore, when connecting, adjusting resistance R 1 (205) had better not be infinity when regulating resistance R 1 and R value (R at time be the resistance value of sample).

In the mode of an optimization, the scope of therefore regulating the resistance of resistance R 1 (205) is 1Mohm---8Mohm.

The utility model device can be used to collect multiple sample, and usually, the resistance value of various samples is not quite similar, and promptly the resistance R value during conducting has nothing in common with each other between electrode.Among the preferred embodiment, regulation voltage is controlled and the collecting amount of regulating different samples with resistance simultaneously.For example, when collecting saliva sample,, preestablish a supply voltage, control the saliva collection amount through regulating resistance according to the resistance value of saliva; And when the collection body fluid samples,, reset another supply voltage value then according to the resistance value of body fluid, again through regulating the collecting amount that resistance value is regulated body fluid.

Handle 300

In other concrete embodiments, Fig. 7 and shown in Figure 8, collecting part 100 can be connected with a handle 300.The cavity design can be arranged in the handle 300, comprise the cavity 3011 of an end opening.Handle 300 can connect collecting part 100 and is fixed on the handle 300 through adhesive board 400.Fixing mode has a lot; For example can be; Can be provided with hasp on the adhesive board 400 sample collection parts 100 are fixed on an end of handle 300, also can one end 102 of collecting part 100 be bonded on the adhesive board 400, such as adopting glue through being stained with sticking form.In a preferred mode, electronic installation 200 is positioned at 3011 li of the cavitys of handle 300.More specifically, the openings of sizes of processor 202 and cavity 3011 is suitable, can let whole electronic installation 200 be positioned at cavity 3011.An end 2011 that is positioned at the electrode 201 of cavity passes adhesive board 400 and contacts with an end 102 of collecting part 100.Simultaneously, electronic installation 200 comprises a signal electron element 203, and identification signal is sent through element 203.This light-emitting component 203, for example light emitting diode can be integrated on the processor 202.When collecting fluid sample; Put into collection body fluid samples in people or mammiferous certain organ to an end 101 or the whole collecting part 100 of collecting part; Collecting part 100 contact liqs are also slowly filled by liquid, when the fluid sample of 100 li of collecting parts arrives the end 102 of collecting part, are positioned at the two or more electrodes that are positioned at collecting part end 102 equally 201 that separate of fluid sample conducting of collecting part 100; The electrode of this conducting forms current return; Let processor 202 produce an electronic signal, this electronic signal lets light-emitting component 203 send identification signal, such as; Diode emits beam, and points out the fluid sample of this collecting part 100 to collect the amount that needs.

In another optional mode, gathering-device also comprises the testing element of analyte in the test sample book.In a concrete mode, testing element is positioned at a handle 300.Handle 300 is connected with collecting part 100, and the fluid of collecting part 100 can be flow on the testing element.Also can pass through other water conservancy diversion material, for example filter paper etc., overlap joint indirectly.Let the fluid from collecting part 100 flow on the testing element through the water conservancy diversion material.In another concrete mode, electronic installation 200 also is positioned at housing, and the electrode 201 of electronic installation contacts with collecting part 100.When in use, if collecting part 100 is collected enough samples are arranged, electronic installation 200 sends identification signal through light-emitting component 203; The expression sample is enough; Can stop to collect, then, the fluid sample that is collected on the collecting part 100 passes through the sample region of acceptance successively; Marked region, surveyed area; Pass through the testing result of test zone on the read test element at last.

Handle 300 can also comprise a passage or cavity; One end of this passage or cavity communicates with cavity 3011; The other end of this passage is with handle end 303 or be affectedly bashful position 302 and communicate; When handle front end 301 had light source to exist, light can pass passage and shine handle end 303 or shine and be affectedly bashful position 302, and the person that collects the sample like this can directly see light and stop to collect.Certainly; In a selectable mode; Handle 300, cavity or one or more parts of being affectedly bashful in the position 302 (middle-end) are formed for the material that can be seen through by light, for example transparent plastic, glass etc., and being arranged in the light that the light-emitting component 203 in chamber sends can be observed.

In another preferred mode, handle end 303 is designed with special reflective or printing opacity design, is scalloped recess 3031 or on handle end, is designed with sags and crests 3032 like end.Some sample is when collecting; Because the part restriction, need stronger light occur in handle end 303 could be received by the operator, such as: when collecting the human body saliva sample; The operator holds the handle of gathering-device 700 and is affectedly bashful portion 302; Collecting part 100 is put into mouth collect saliva sample, at this moment, operator's eyes often are merely able to see the handle end 303 of gathering-device 700.

Special construction 3031, the 3032 main effects of handle 300 ends 303 are that the light source that is mapped to end 303 can repeatedly be launched and/or refraction, finally make more rays received by operator's eyes.Its main action principle is shown in figure 12, and a is the handle material, and b is the outside air layer, and c is the interface of handle and air, and d is the normal vertical with interface c.The density of handle material is greater than the density of air; When light A1 is delivered to handle end 303 and arrives handle and during the e point of the interface c of air, according to reflection of light and refraction law, emission and refraction take place on the interface c of light A1 in handle from handle front end 301; The light A2 that reflects is still in handle a; The light A3 of refraction then gets among the air b, and incident angle α equals reflection angle β, and refraction angle γ is greater than incident angle α.Light A2 in handle material a possibly be injected into other interface places of handle material a, and reflection and/or refraction take place once more; The light A3 that gets into air layer b then possibly directive operator eyes direction received by the operator, also possibly be injected into other directions of air layer b, also possibly be injected into to reflect once more on other interfaces of air b and handle a and/or reflect.Reflection and/or refraction through light A2 and A3 can derive more rays.And the like; The most light that are delivered to handle end 303 from handle front end 301 all can be the same with light A1, and the special construction 3031,3032 through handle end reflects and reflects; The light of reflection and refraction is reflected and reflects, and derives more rays.Thereby; Just having more rays is refracted in the ambient air through handle end 303; And have more rays to be reflected at the air place of handle end 303, final, light significantly increases in handle end 303 ambient airs; Accordingly, these light quantity of being injected into operator's eyes also can increase.Therefore, the light of the observed handle end 303 of operator can brighten.

In other preferred modes; For the light source that makes handle front end 301 can effectively be transferred to handle rear end 303; Be designed with cavity in the handle 300 again; The light source of front end 301 can directly be transferred to rear end 303 through cavity, the loss of avoiding light in through the transmission of handle material, to reflect away.More excellent, the front end 301 of handle uses lighttight material to process with middle-end 302, has only terminal 303 to use light transmissive material to process, and so also can effectively reduce light transmission to terminal loss.

A practical implementation device with regard to the utility model carries out detailed structure explanation and method of application explanation below.

In the specific embodiment of the utility model, like Fig. 1 and shown in Figure 7, this gathering-device 700 comprises the collecting part 100 and electronic installation 200 of absorption fluids sample.Electronic installation 200 comprises electrode 201, processor 202 and light emitting diode 203, and further, electronic installation 200 also comprises power supply (battery) 204, and is as shown in Figure 9.Wherein, collecting part 100 is connected with electronic installation 200.More specifically, an end 102 of collecting part and electronic installation 200 an assembly--an end 2011 of-electrode 201 is connected.The other end 2012 of electrode is connected with processor 202.Light emitting diode 203 is connected on the processor 202.

When the use of reality operation, conducting has certain contingency between two electrodes 201, when collecting, only accumulates in two electrode (this moment electrode may conducting) such as, sample, and other collecting part places do not collect.Like this, can cause the collecting amount of sample and original collecting amount of setting to have deviation.Therefore, more stable in order to make testing result, can increase the quantity of electrode, and a plurality of electrodes 201 are evenly distributed in the end 102 of collecting part 100.In a preferred specific embodiment, the equally distributed electrode 201 in the electronic installation 200 be 5 (J1, J2, J3, J4, J5).In the preferred mode, an electrode J5 in 5 electrodes is as power end, and another electrode J2 is an earth terminal, and its excess-three electrode J1, J3, J4 all are in series with and regulate resistance R 1 (205), and be as shown in Figure 4.Be connected with three electrode J1 that regulate resistance R 1 (205), J3, J5 input end A, B, C through adopt with gate logic (A*B*C=Y promptly works as A, B, when C3 input end all had high level, output terminal Y also exported high level; If A, B, C end have 0, and when 1 or 2 ends had high level, output terminal Y is did not have high level output) the processor 202 output signal Y of principle, output terminal Y is connected with light-emitting component 203.As three electrode J1, J3 during the equal conducting of J4 input end, be connected with the also conducting of output terminal of light-emitting component 203, thereby cue is sent in light-emitting component 203 conductings.Three electrode J1 wherein, J3, each the electrode fundamental diagram among the J4 is as shown in Figure 5, and its principle of work is formula (3):

Vcc/(R+R1)＝Vt/R1

Vcc is the supply voltage that J5 provides, and Vt is the cut-in voltage of processor 202, and R is the electrode resistance, and R1 is for regulating resistance value.When this formula (3) is set up, when promptly reaching the electric current of electrode conduction, this electrode J1; J3; The J4 conducting, according to the principle of gate logic (A*B*C=Y), also conducting of output terminal Y; Thereby make light-emitting component 203 conductings, signal (LED light lamp is bright) the prompting sample collection amount of sending through light-emitting component has reached predetermined value.

Wherein, the cut-in voltage Vt of processor 202 is relevant with the product type that begins to select, in case selected model is fixed value.Equally, when reducing power source voltage Vcc, resistance R need reduce, the then corresponding increase of sample collection amount, on the contrary Vcc increases, and resistance R increases, and the sample size of collection reduces.And the relation of regulating resistance R 1 and R also is corresponding, when R1 increases, needs R to reduce, and the sample collection amount increases, and perhaps, R1 reduces, and then R increases, and the sample collection amount increases and decreases few.

More specifically, the electrode J2 of earth terminal adopts the principle control of using metal-oxide-semiconductor, and is shown in Figure 6.I.e. when supply voltage is 0 (when gathering-device did not use, power supply was in off-state), ground-electrode J2 input end is a high-impedance state, is equivalent to break off, promptly processor 202 is in closed condition.Like this; Can guarantee that the utility model device is not when collecting fluid sample; Electronic installation 200 is in off-state, and both energy efficient guaranteed the accuracy (can not make collecting amount not reach predetermined collecting amount because of the loss of power supply) of when this device 700 is collected sample, collecting again.In concrete embodiment, the resistance of the adjusting resistance R 1 (205) of connecting with three electrodes is can 1-20Mohm.One more specifically in the embodiment, this resistance is 1-8Mohm.

Among the embodiment, like Fig. 7 and shown in Figure 8, also comprise a handle 300 more specifically, this handle 300 is connected with an end 102 of collecting part 100.This handle 300 has the front end 301 that links to each other with collecting part 100, is suitable for the portion of being affectedly bashful (middle-end) 302 and handle end 303 that hand is taken.In the preferred mode, the front end 301 of handle has cavity 3011, and is preferred, and all elements of electronic installation 200 integrate, and are positioned at handle cavity 3011.

Shown in Figure 8, when electronic installation 200 is positioned at the cavity 3011 of handle 300 front ends, and an end 2011 of electrode 201 is when being positioned at an end 102 of collecting part 100; The other end 101 of collecting part 100 contact and collects sample with the sampling position, collect a certain amount of sample after, fluid sample edge 101 ends in collecting part 100 are mobile to 102 ends; Finally contact with electrode one end 2011 that is positioned at 102 sections; Along with the continuous increase of sample, the sample size at an end 2011 places of 5 electrodes also increases gradually, and is final; Enough sample sizes make electrode 201 conductings; The high level that electrode 201 conductings produce makes processor 202 output high level, thereby makes light-emitting component 203 conductings, i.e. lumination of light emitting diode.

Light emitting diode 203 is positioned at the cavity 3011 of handle front end 301; For the light that guarantees to send can be received by the operator, handle 300 materials that comprise electronic installation can be light-transmitting materials, like transparent plastic; What use in glass or the like, this instance is transparent ABS material.When collecting part 100 is collected the sample size that needs; Electrode 201 conductings, electronic installation 200 work emit beam light emitting diode 203, and this light is positioned at the cavity 3011 of handle front end; Because of handle is a light-transmitting materials, then the light that sends of this diode 203 can be transferred to whole handle 300.The operator just can see that whole handle 300 is illuminated by light, thereby stops to collect sample.But collecting the part sample; During such as saliva sample; What normally the operator held handle is affectedly bashful position 302, mouthful carries out the collection of saliva sample with what collecting part 100 was put into the operator, like this; The operator just is difficult to observe the front end 301 and the middle-end (being affectedly bashful portion) 302 of handle, can only remind the operator whether sample collection is enough through the light of handle end 303.And behind the whole handle of light transmission that the light emitting diode 203 of handle front end 301 sends; Handle end 303 is because of apart from handle front end 301 farthest; Light constantly reflects in transmission course; The light that arrives end 303 has quantitatively still all reduced much in the brightness, so, the too weak phenomenon of not knowing or not observing of observing of light may take place.In the present embodiment, increase some groove design 3031 and sags and crests design 3032, make light quilt reflection and the refraction repeatedly that shines handle end 303, increase the quantity and the intensity of light, make the operator more be prone to observe in handle end 303.Shown in figure 11, be designed with scalloped recess 3031 and a large amount of sags and crests 3032 in handle end 303.When light arrival handle end 303, shown in figure 13, light is in interface place generation reflection and the refraction of groove 3031 with air, and light reflected arrives the interface place of another groove 3031 and air once more, takes place once more to reflect and refraction.So circulate repeatedly, amount of light increases, and being refracted to airborne amount of light increases, thereby the amount of light that gets in operator's eye also increases.After the light emitting diode 203 of the cavity that is positioned at handle front end 301 3011 emitted beam, the operator more was prone to observe light in handle end 303.Figure 14 is the concrete reflected refraction synoptic diagram of the Ray Of Light of this instance; The scalloped recess 3031 that the light D that sends from light emitting diode 203 is transferred to handle end 303 is during with the interface g of air; Emission and refraction law according to light; Reflection and refraction take place, and form reflection ray E and refracted ray F, this refracted ray F may be injected into the operator the eyes observation scope and seen by the operator; Reflection ray E projects the interface h place of another groove 3031 and air in handle end, and reflection and refraction take place once more, forms another reflection ray G and another refracted ray H.Reflection ray G may project handle end 303 another positions, and reflection and/or refraction take place once more.Refracted ray H then shines the interface k place of air and groove, and reflection and/or refraction also can take place again.

Among another embodiment,, can be designed with fence 500 on the collecting part 100 in handle 300 and collecting part 100 junctions.Like Fig. 7 and shown in Figure 10, this fence 500 is positioned at an end 102 places of collecting part, and fence one end is connected with the front end 301 of handle 300.More specifically, fence 500 can with handle 300 one-shot formings.Electronic installation 200 is positioned at the front end cavity 3011 of the handle 300 that has fence 500, and an end 2011 of an element of electronic installation 200---electrode 201 contacts with an end 102 of collecting part 100.In the present embodiment; One end 2011 of electrode is positioned at collecting part one end 102; For the sample that guarantees to collect can not soak other electronic components of electronic installation 200; The adhesive sheet 400 that between electronic installation 200 and collecting part 100, has a waterproof material to process, an end 2011 of electrode 201 passes adhesive sheet 400 and contacts with collecting part 100.When collecting part 100 with after handle 300 is connected, an end 102 of collecting part is positioned at the inboard of fence 500.The interior diameter of fence 500 can be identical with the diameter of collecting part 100.The height of fence 500 is not limit, and is high more in principle good more, but preferably is no more than half height of collecting part 100.In the specific embodiment, the height of this fence 500 is identical with the height that electrode 201 is positioned at collecting part 100.

Because of fence 500 is set up the place, the place that links to each other with electrode 201 of collecting part 100 just.After setting up fence 500, can reduce or avoid sample just to contact, prolong the time that electrode 201 touches sample, also make in the collecting part 100 and can be full of sample more fully, avoid contingency with electrode 201 at the collection initial stage.In addition, fence 500 is set after, the part that collecting part 100 has fence also not too can move at sampling point, thereby can not cause electrode 201 directly contact sampling points or sample and mislead.

Usually, general sample collection parts 100 can have the sample size above 1ml when collecting full sample, carry out smoothly and the sample that is used to detect can guarantee to detect between 0.5ml to 1ml.Greater than the sample size of 1ml, can guarantee that then sample can also have the residue sample to be used for the secondary affirmation after to be detected.

Form 2 has been enumerated the utility model device and fence has not been set and is provided with the just data of the sample collection amount of two kinds of fences.

(gathering sample size is 32 parts)

Table 2:

Can find out that through table 2 in this gathering-device 700, set up fence 500 front and back and fence from low to high, the sample collection amount obviously descends less than the ratio of 0.5ml, like this, can guarantee that the sample size that this gathering-device 700 is collected can detect.
