Description

The collection and detection method of sample

Technical field

The present invention relates to a kind of method of collection and detection liquid sample, the especially collections and inspection in quick diagnosis field The method for surveying analyte in liquid sample, such as urine collecting and detection method.

Background technique

Currently, for detect in sample whether the detection device containing analyte, be largely used to hospital or family In, these detection devices for being applied to quick diagnosis include one or more detection reagent items, for example early pregnancy detects, drug abuse Detection etc..The detection device of this quick diagnosis is very convenient, can be at one minute, or at most ten minutes or so are detecting Testing result is obtained on reagent strip.

Illicit drugs inspection is widely used, be usually used in prohibition of drug department, public security bureau, narcotic house, medical center, country conscription physical examination at Etc. mechanisms.Illicit drugs inspection wide variety, number is frequent, can be automatically separated the illicit drugs inspection urine cup of remaining sample Yu detected sample With the huge market demand, after detection is completed, sample in urine cup will be by for illicit drugs inspection urine cup currently on the market To detection reagent pollution and cannot continue on for second of confirmation detection, such as United States Patent (USP) 7300633 describe as.

Although detected sample in the conventional technology, can be allowed to be isolated with the sample of collection, cost Height, and do not allow easy to operate.Such as United States Patent (USP), the piston urine cup that the patent No. 7300633 describes, when the mistake for pushing piston to advance Cheng Zhong, allows liquid sample in collecting chamber, such as urine, is transferred to test chamber from collecting chamber, there is test sample in test chamber The testing element of middle analyte, and the liquid sample of collecting chamber is kept apart by piston, so that two local samples are not It can obscure, be detected so as to be used to later confirmation.Although can isolate out the sample of detection and the sample of collection in this way, Be this piston urine cup it is at high cost, and operation is not easy, and pushes piston to need bigger strength after all, this is because living Plug needs to reach transfer sample, is necessarily required to play the effect of hydraulic seal with the wall of piston, achievees the effect that sealing needs allow Piston and plunger shaft closely combine.

For another example United States Patent (USP) 8992855 describes a kind of device for collecting liquid sample, which includes connecting with lid The piston structure for being integrated and moving together with lid separates although can detecte sample and the sample of collection, when detection It after sample enters test chamber, needs to overcome very big pressure just to can enter, and needs the size of sophisticated design lid and rim of a cup, The piston being linked together in this way with lid can accurately be just inserted into disengagement chamber.

In addition, carrying out confirmation inspection if necessary to subsequent after the completion of the preliminary tests such as these traditional collections and detection device It surveys, needing an entire collection and detection device to be transported to, the progress of confirmation testing agency is further to confirm detection, this just brings Many problems, at least have a problem in that first, and major part liquid is collected at present and detection device is provided only with Preliminary detection Chamber.When if necessary to subsequent confirmation detection, the whole device containing urine and detection reagent item can only be sent to confirmation detection machine Structure is detected.Sample in urine cup is possible to the pollution by detection reagent.Second, whole device is sent to confirmation detection When mechanism, since rim of a cup is larger, liquid has the risk of leakage during transportation, this is just needed more at allowing device to have originally There is better seal effect, to reduce the risk of leakage to the greatest extent；Third, by whole device be transported to confirmation testing agency it Afterwards, confirmation testing agency needs huge low temperature warehouse to store entire detection device, prevents liquid sample rotten, in order to it is subsequent can Energy further confirms that detection is prepared, and confirmation testing agency (being properly termed as secondary detection mechanism) cost is caused substantially to rise in this way It is high.

It for above-mentioned some technical problems, therefore needs to make improvements, other approach is provided and solves existing traditional skill The deficiency of art.

Due to needing the relationship with linkage between the first sealing element, the second sealing element and third sealing element, Therefore, between these sealing elements, it is necessary to which some linkage structures are set.

The third aspect, the present invention provide the linkage structure of sealing element, the sealing element including sample collection device, sealing The linkage of seal process is realized between element by linkage element.

In some preferred modes, linkage structure includes the first sealing element for sealing the first chamber and for sealing Second sealing element of the second chamber is linked between the first sealing element and the second sealing element by the first linkage element.One In a little preferred modes, linkage structure includes that the first sealing element for sealing the first chamber and the third for sealed passage are close Element is sealed, is linked between the first sealing element and third sealing element by the first linkage element.In some preferred modes, Linkage structure includes the second sealing element for sealing the second chamber and the third sealing element for sealed passage, the second sealing It is linked between element and third sealing element by the second linkage element.In some preferred modes, including for sealing the First sealing element of one chamber, the second sealing element for sealing the second chamber and the third sealing element for sealed passage, It is linked between first sealing element and the second sealing element by the first linkage element, the second sealing element and third sealing element Between by the second linkage element link.In some preferred modes, including for sealing the first chamber the first sealing element, For sealing the second sealing element of the second chamber and for the third sealing element of sealed passage, the first sealing element and second close It seals between element and is linked by the first linkage element, pass through close-fitting or the company of fixation between the second sealing element and third sealing element Connect linkage.

In some preferred modes, the linkage between the second sealing element and third sealing element, which can be, passes through fixation Connection is to realize.In some preferred modes, the linkage between the first sealing element and third sealing element, which can be, to be passed through It is fixedly connected to realize.

In some preferred modes, the first linkage element is interlocking bar.In some preferred modes, the second linkage member Part is set bar.In some preferred modes, the linkage refers to synchronous rotation.It is described in some preferred modes Linkage refer to it is synchronous to mobile close to the direction of sample interior.

In some preferred modes, the first linkage element is interlocking bar, and the both ends of interlocking bar are separately connected the first sealing Element and third sealing element, make one of the first sealing element and third sealing element rotate when, be able to drive in addition one of with Rotation, this rotate with it can be synchronous, be also possible to the drive of discontinuity, but it is this rotate with it is usually same Direction.In some preferred modes, the interior capping of the first sealing element is equipped with axis hole, and interlocking bar is plugged on the axis hole It is interior.In some preferred modes, the outer capping of third sealing element is equipped with axis hole, and interlocking bar is plugged in the axis hole.? In some preferred modes, interlocking bar can pass through the first chamber and connect the first sealing element and third sealing element.

In some preferred modes, interlocking bar has certain shape, and usually this shape is not circular, can To be such as rectangular, semicircle or triangle, correspondingly, the axis hole on the first sealing element and third sealing element is also Same shape, then, circumferential limit is just carried out by this shape between interlocking bar and axis hole, opposite turn will not occur Dynamic, therefore, interlocking bar can drive the first sealing element and third sealing element to be rotated by two axis holes, to realize Linkage.In other possible modes, interlocking bar and axis hole are also possible to the circular hole of close-fitting, and the power to link at this time is from connection Lever and axis hole are adjacent to the frictional force between face.In other possible modes, interlocking bar and axis hole are also possible to step-by-step movement The relationship that is linked, it is this it is step-type be linked under relationship, interlocking bar or axis hole can independently rotate certain angle, Then resynchronisation rotation, while rotation, the first sealing element can be sealed the first chamber, close in the first sealing element During sealing the first chamber, third sealing element can be to being sealed at separation.

As another way of realization being linked, interlocking bar is equipped with axis hole, the first sealing element or third sealing Element is equipped with the co-operating member to link with axis hole, and co-operating member is of similar shape with axis hole, this shape is to deviate connection Lever axle center, or be non-round, so that interlocking bar and co-operating member can be realized linkage.Some preferred In mode, interlocking bar can also with co-operating member is step-type is linked.

In some preferred modes, linkage structure can also include for the second sealing element and the third sealing member of linking Second linkage element of part.Second linkage element is the short object of set bar or analogous shape, and it is close that set bar can be connected in second It seals on one of element or third sealing element, and in one of other upper setting and the matched linkage hole of set bar, together Sample, set bar and linkage hole also have certain shape, and this shape is similar with interlocking bar, can deviate the second sealing element Perhaps it is for example rectangular, semicircle or three to be perhaps that non-round this shape can be for third sealing element rotation center It is angular etc., one of in addition it is rotated with it so that set bar and/or linkage one of hole are able to drive, it is this to turn therewith It is dynamic to can be synchronous, it is also possible to the drive of discontinuity, this rotation can be equidirectional, it is also possible to opposite direction, While rotation, third sealing element can be to being sealed at separation, the process at third sealing element hermetic separation In, the second sealing element can be sealed the second chamber.

The combination of first chamber and the second chamber with separate

Sample testing apparatus of the invention, including two for collecting chamber the-the first chamber 1 and the second chamber 2 of liquid sample, First chamber 1 is used to collect the liquid sample of initial detecting, and the second chamber 2 is used to collect the liquid sample of secondary-confirmation detection, and first Chamber 1 and the second chamber 2 can be combined together, and can receive the liquid sample collected for the first time simultaneously, that is to say, that be used Person is when using product of the invention, it is only necessary to primary collection operation, so that it may at the same it is all real to the first chamber 1 and the second chamber 2 The injection of existing liquid sample.

In some embodiments of the invention, as shown in Fig. 2,7,8, a channel 5, channel 5 is arranged in the bottom of the first chamber 1 One end be connected to the first chamber 1 inside, the other end is externally connected to, and the second chamber 2 can be assembled in the channel 5, the bottom of the second chamber 2 Sealing forms a plug to the channel 5, as previously described, because sample has certain mobility, then when user exists When collecting sample, it will usually oral area will be collected upward, such as Fig. 9, shown in 10, the first collection port 6 upward, channel 5 (namely second The oral area 7 of chamber 2) positioned at the lower section of the first collection port 6, user injects the sample of mobility from the first collection port 6 for location This, sample can be flowed in the second chamber 2 due to gravity, the inner wall along the first chamber 1, thus collected by the second chamber 2, also It is to say, the second chamber 2 in bottom can be preferentially packed into sample, and then the first chamber 1 will continue to be loaded into, until reaching one-time detection Required amount.

Since the liquid sample in the first chamber 1 is used directly to detect, and the liquid sample in the second chamber 2 may be close It is honored as a queen and is transported, enter confirmation testing agency and carry out secondary-confirmation detection, therefore, and the liquid sample in the first chamber 1 is Passed through an initial detecting, become non-primary sample, then detect to the sample in the first chamber 1, secondary-confirmation is detected As a result accuracy can have an impact, therefore, it is necessary to separate the first chamber 1 and the second chamber 2, furthermore, it is desirable to meet the first chamber 1 and It can be individually formed the cavity of a sealing after the separation of two chambers 2, wherein by the liquid sample encapsulation respectively in it, while also to expire During the first chamber 1 of foot and the second chamber 2 separate, sample will not be sealed from separation place, this is just to the structure and the at separation One chamber and the respective sealing structure of the second chamber all require.

In some preferred modes, the second chamber 2 collects sample by the first chamber 1, and the second chamber 2 can with the first chamber 1 The connection or combination of disassembly, the second chamber 2 are combined during sample collection with the first chamber 1, and the second chamber 2 is complete in sample collection It can be by from the first intracavitary release after.

In some preferred modes, the second chamber 2 includes the second collection port for collecting sample, collects sample in the second chamber This when, the second collection port can be with first intracavitary portion's fluid connections.The second chamber is set to the first chamber in some preferred modes Bottom.In some preferred modes, the first chamber 1 has the first collection port 37 for collecting sample.Some preferred In mode, the first collection port 37 is consistent with the opening direction of the second collection port 38, in this way can utmostly by structure come The collection efficiency of the second chamber 2 is improved, if the first collection port 37 is different with the direction of the second collection port 38, sample passes through the first chamber It is smooth when just identical not as good as collection port direction when into the second chamber, it be easy to cause stagnant on surface or side wall It stays, and due to direction difference, corner will necessarily be generated, sample is then possible on the corner to deposit, is unfavorable for collecting, siltation Locating extra sample also can be in the possibility for increasing leakage, in addition, if collection port direction is different, it is likely that when will cause sealing That links is not smooth.

At separation

For this purpose, the present invention also provides at the separation of a kind of first chamber 1 and the second chamber 2, as shown in fig. 7, this separation is sentenced The form in channel 5 embodies, and when the first chamber 1 and the second chamber 2 combine, shows as the first chamber 1 and second again at this separation One junction of chamber 2, the initial stage, sample collection device is not yet by use, the second chamber 2 is assemblied on the first chamber 1, at this time As previously mentioned, the second chamber 2 prevents sample from leaking out at channel 5 when initial be packed into as a plug at channel 5, Moreover, the second chamber 2 has to exit out of channel 5 without taking extra sample out of, this is just right after the completion of sample is packed into Assembly between second chamber 2 and channel 5 and it is sealed with higher requirement, to allow inside of the liquid sample as far as possible to the second chamber 2 And the internal flow of the first chamber 1 other than channel 5, rather than deposit at the assembly in the second chamber 2 and channel 5.

For this purpose, devising following several forms:

It is possible, firstly, to the mode taken is, (i.e. the second chamber 2 is opened towards this in the first chamber 1 for the oral area 7 of the second chamber 2 Mouthful) must at least be flushed with the surface of channel 5 towards the first intracavitary opening 15, comparatively the face flushed is not easy to be formed Deposit point, especially to be avoided, the surface of the opening in channel 5 is lower than the oral surfaces of the second chamber 2, in this case, no It can avoid ground, liquid sample can enter in the gap between 2 oral area of channel 5 and the second chamber, thus when the second chamber 2 exits It can flow out therewith.In addition it should be pointed out that since the second chamber 2 needs the second sealing of one and the second sealing element 11 Position 13, this second sealing position 13 may exceed its oral area 7, and be formed between the second sealing position 13 and oral area 7 One shoulder 14, as shown in figures 3 and 6, the guarantee that we need at this time to be shoulder 14 intracavitary open with channel 5 towards first The surface of mouth 15 flushes.

Then, this form may also is that the second collection port 7 is slightly above the opening 15 in channel 5, alternatively, the shoulder of the second chamber Portion 14 is slightly above the opening in channel 5, in this way, the liquid sample not being packed by the second chamber 2 would generally be along this from high to low Layered structure flow in the first chamber 1 other than channel 5.

Or second collection port 7 and channel 5 opening 15 surface between form one and incline gradually downward from inside to outside Oblique inclined-plane, alternatively, forming one between the surface of the opening 15 of the shoulder 14 and channel 5 of the second chamber from inside to outside gradually downward Inclined inclined-plane, then the form on this inclined-plane can be more conducive to not leave entrance along it by the liquid sample that the second chamber 2 is packed into Into the first chamber 1.

The form that channel 5 is sentenced in separation embodies, and channel 5 is the element of a both ends open, and one end connection is external, and one end connects In logical first chamber 1, since the second chamber 2 can assemble wherein, then the second chamber 2 is possible to meeting along channel 5 in some cases It enters in the first chamber 1, such case has to be absolutely avoided.On the one hand the leakage part of the second chamber 2 can pollute first Liquid sample in chamber 1, second aspect, if the second chamber 2 is not clogged or is pulled out, channel 5 is just at the first chamber One loophole, liquid sample can be from wherein a large amount of leakages, it is therefore necessary to the position limiting structure that the second chamber 2 moves inward be arranged.

As shown in Fig. 2,7,8 or 9, it is equipped with a between outer land terrace 8 in channel 5, is come with this between outer land terrace 8 for line of demarcation It sees, channel 5 is less than between outer land terrace 8 close to this external side in internal diameter of the outer step surface 8 close to the part in 1 this direction of the first chamber To part internal diameter, thus the inner wall in channel 5 forms inner small and outside big structure, and this between outer land terrace 8 is lucky It is the line of demarcation of size, that is to say, that between outer land terrace 8 can be used as a position limiting structure.

In order to preferably be adapted to this position limiting structure, an interior step surface 9 can also be set on the outer wall of the second chamber 2, Step surface 9 is as from the point of view of line of demarcation in using this, and the outer wall of the second chamber is in interior step surface 9 close to the portion of 1 internal direction of the first chamber The internal diameter divided is less than the second cavity outer wall in interior step surface 8 close to the internal diameter of this external direction part, that is to say, that interior step surface 9 can form a cooperation between outer land terrace 8, to be limited to the inside movement of the second chamber 2, in original state, and second Chamber 2 is assemblied in the first chamber 1, and interior step surface 8 and between outer land terrace 9 are usually to be engaged at this time, when interior 8 He of step surface When between outer land terrace 9 is engaged, the bottom of the second chamber 2 is flushed with the oral surfaces of channel 5 outwardly.Later with sealing It carries out, interior step surface 8 and between outer land terrace 9 will do it separation, and the second chamber 2 can be gradually rejected outward.

A kind of way of realization of above-mentioned only this position limiting structure, it should be appreciated that position limiting structure is that one kind can be into The conventional mechanical structure of row extension and application all belongs to as long as can satisfy the structure for preventing the second chamber 2 from moving inward without limitation In this column, for example, snap ring, elastic component etc., will not enumerate herein.

In some preferred modes, sealing structure, so-called dress can also be set on the fitting surface in the second chamber and channel Refer to the outer surface of the second chamber and the inner surface in channel with face, sealing structure can use the form of Sealing shield ring 37, sealing Retaining ring 37 can limit the assembly in the second chamber and channel, that is, play the role of it is identical with position limiting structure above-mentioned, can also be to Sealing function is played in the separation of two chambers and channel.In some preferred modes, Sealing shield ring uses O-ring.Some preferred Mode in, Sealing shield ring 37 use hair brush structure, hair brush structure can when the second chamber exits channel, scrape the second chamber table Face, it would be possible to which the sample adhered to thereon strikes off, and certainly, O-ring can also function as described above.

In some preferred modes, sealing structure and position limiting structure can also be not arranged in the assembly in channel and the second chamber On face, as long as can function as described above, the rigging position of structure is not the range of the invention to be limited.

The collection method of sample

The present invention provides a kind of method for collecting aforementioned sample, and this method, which uses, has the first chamber 1 above-mentioned and the second chamber 2 Sample collection device, the first chamber 1 is for collecting liquid sample, and the first chamber 1 has a sample entrance port 4, and the second chamber 2 is for receiving Collection confirmation detection liquid sample, the detection opportunity and testing goal of the first chamber 1 and the second chamber 2 are different, but detect institute's needle Pair be sample that same batch is collected into.In order to realize that same batch is collected and gradation detects, the first chamber 1 and the second chamber 2 were both It can carry out being detected respectively after releasing with a batch of collection when combining in conjunction with can separate again, or It is separated after detection, the second chamber 2 individually enters secondary detection program.Sample testing apparatus further includes for sealing the first chamber 1 The first sealing element 10, for sealing the second sealing element 11 of the second chamber 2, and the separation to the first chamber 1 and the second chamber 2 The third sealing element 16 that place is sealed, at separation, i.e., channel 5 above-mentioned.

In some preferred modes, for the first sealing element 10 during sealing the first chamber 1, the second chamber 2 can be by The sealing of second sealing element 11.In some preferred modes, the first sealing element 10 leads to during sealing the first chamber 1 Road 5 can be sealed by third sealing element 16.In some preferred modes, the second sealing element 11 and third sealing element 16 One of with the linkage of the first sealing element 10 and the second sealing element 11 links with third sealing element 16；Or second sealing element 11 and third sealing element 16 with the first sealing element 10 link.In some preferred modes, in all seal process Before, channel 5 is clogged by the second chamber 2, at this point, the first chamber 1 forms the entirety being internally connected to outer closure with the second chamber 2. In some preferred modes, in seal process, the second chamber 2 is displaced outwardly relative to channel 5.

Sealing element

As previously described, when the first chamber 1 and the second chamber 2 are in bonding state, only one of chamber can be carried out Sealing, because the two has common opening, and a channel by a channel 5 as both connections, when the first chamber 1 After the separation of the second chamber 2, need independently to be sealed the second chamber 2, such second chamber 2 can be independently to liquid-like therein Originally it is sealed, it is therefore desirable to have the sealing device individually for the second chamber 2, when the first chamber 1 and the second chamber 2 are in isolated process In, the first chamber 1 will necessarily generate one in addition to (this original opening can be by first for original opening due to the second exiting for chamber 2 Sealing element 10 is sealed) except the new opening (i.e. the outside opening 15 in channel 5) that may leak out liquid, also need at this time This opening 15 is sealed, prevent liquid sample from flowing out, it is therefore desirable to which one for the sealing device at separation.

In view of above-mentioned reason, the present invention provides the specific sealing structure of the first chamber 1 and the second chamber 2, these specific sealings Structure includes the first sealing element 10 for sealing the first chamber 1, for sealing the second sealing element 11 of the second chamber 2, and When the first chamber 1 and the second chamber 2 separate, the third that (i.e. channel 5) is sealed at the separation of the first chamber 1 and the second chamber 2 is close Seal element 16.

In some preferred modes, the oral area 6 of the first sealing element 10 and the first chamber 1 by the first helicitic texture 17 into The oral area 7 of row sealing, the second sealing element 11 and the second chamber 2 is sealed by the second helicitic texture 18, third sealing element 16 and separation at (i.e. channel 5) be sealed by third helicitic texture 19.

Be as shown in Figure 7 whole device sealing before state, at this point, the first sealing element 10, the second sealing element 11 with And third sealing element 16 does not start to seal, when user is collected into proper amount of liquid sample from the oral area 6 of the first chamber 1 Afterwards, device can be sealed, the first sealing element 10 lid is closed into the oral area 6 to the first chamber 1, the rotation of the first sealing element 10 Lid is closed onto the oral area 6 of the first chamber 1, is realized the sealing to the first chamber 1, is sealed in the first sealing element 10 to the first chamber 1 During, the second sealing element 11 is sealed the oral area 7 of the second chamber 2, or in the first sealing element 10 to the first chamber 1 During being sealed, third sealing element 16 is sealed channel 5, alternatively, in the first sealing element 10 to the first chamber 1 During being sealed, the second sealing element 11 and third sealing element 16 are respectively sealed the second chamber 2 and channel 5, When the first sealing element 10 completes the sealing to the first chamber 1, the second sealing element 11 and third sealing element 16 have been distinguished The sealing to the second chamber 2 and channel 5 is completed, alternatively, during the first sealing element 10 is sealed the first chamber 1, the Two sealing elements 11 are sealed the second chamber 2 with the rotation of the first sealing element 10, at the same time, third sealing element 16 Also channel 5 is sealed rotating with it, the sequence for sealing completion is that the second sealing element 11 is completed first to the second chamber 2 Sealing, the second chamber 2 assembly at this time completes, although formed one it is whole be in the first chamber 1 actually with Second sealing element 11 is separated into the state of an individual cavity, can be separated at any time from the first chamber 1, then third is close And then envelope element 11 completes the sealing to channel 5, the first sealing element 1 continues to rotate until completing the sealing to the first chamber 1.

View of the above, it will be seen that the second sealing element 11 must be close first to the seal process of the second chamber 2 Envelope element 10 is to carrying out in the seal process of the first chamber 1, seal process of the third sealing element 16 to channel 5, it is also necessary to be It is carried out in seal process of first sealing element 10 to the first chamber 1, and sealing of second sealing element 11 to the second chamber 2 Journey and third sealing element 16 can be what sequence successively carried out, are also possible to overlap to the seal process in channel 5 , it can also be fully synchronized.

Shown in Fig. 8 is a pilot process of sealing, and in state shown in Fig. 8, the second sealing element 11 is complete At the sealing to the second chamber 2, third sealing element 16 will start the sealing to channel 5 at this time, and the first sealing element 1 is in To in the seal process of the first chamber 1, that is to say, that for the length of screw thread, the length of the first helicitic texture 17 is equal to second The sum of helicitic texture 18 and the length of third helicitic texture 19, be just able to achieve in this way the first sealing element 10 to the first chamber 1 into During row sealing,

It should be pointed out that during this sealing, due to the first sealing element 1, the second sealing element 2 and third Sealing element 3 is sealed in such a way that screw thread screws, therefore during being threadedly engaged, these sealing elements Necessarily have the reduction in a height, the reduction in this height, from linkage it is upper for, will push the second chamber 2 towards being detached from the The direction of one chamber 1 is ejected so that the second chamber 2 some be exposed to except the first chamber 1, consequently facilitating by the second chamber 2 from It takes out in one chamber 1, will be described in detail in this linkage element below.

In some preferred modes, sealing element can also realize the sealing to each cavity by way of plug. For example, the first sealing element 1, the second sealing element 2 and third sealing element 3 can use the form of sealing-plug.

In some preferred modes, Sealing shield ring can be set on the inner wall in channel or the outer wall of the second chamber.? In some preferred modes, Sealing shield ring can use flexible structure or hair brush structure, and the effect of Sealing shield ring be can be the When two chambers are exited out of channel, prevents the second chamber or isolated sample exudation.

Linkage element

In order to realize the sealing sequence of the first chamber 1, the second chamber 2 and channel 5, need for the first sealing element, the second sealing Linkage structure is arranged in element and third sealing element, and the effect of linkage structure is, when the first sealing element is close to the progress of the first chamber During envelope, the second sealing element can also be sealed the second chamber, it is possible that state is, when the first sealing element is complete When at sealing, the second sealing element is also completed to seal, alternatively, the second sealing element is before the first sealing element completes sealing Complete sealing.

These linkage structures include the first linkage element for link the first sealing element 10 and third sealing element 16 20, and for link the second sealing element 11 and third sealing element or the second sealing element 11 and the first sealing element 10 Second linkage element 21.

First linkage element 20 is interlocking bar, and the both ends of interlocking bar are separately connected the first sealing element 10 and third sealing member Part 16, make one of the first sealing element 10 and third sealing element 16 rotate when, be able to drive in addition one of rotate with it, it is this Rotate with it and can be synchronous, be also possible to the drive of discontinuity, but it is this rotate with it is usually equidirectional, still Also a possibility that being not excluded for opposite direction.

As the specific implementation form of interlocking bar, the first sealing element 10 is a kind of cup lid, opposed flattened with one Interior capping 22, interior capping 22 be equipped with interior axis hole 23, the upper end of interlocking bar is plugged in the interior axis hole 23, such as the institute of Fig. 2,7,8 The part of the first sealing element 10 shown.In some cases, third sealing element 16 is also a kind of lid structure, has one Opposed flattened outer capping 24, outer capping 24 are equipped with outer shaft hole, and the lower end of interlocking bar is plugged in the outer shaft hole, link in this way Bar can be linked the first sealing element 10 and third sealing element 16 by inside and outside two axis holes, can be synchronized Rotation, then user only needs to rotate the first sealing element 10 of outermost when in use, it will be able to which synchronous drive third is close Envelope element 16 is sealed channel 5.

Alternatively, the part of third sealing element 16 is also possible to the appearance as shown in Fig. 2,7,8, the lower end of interlocking bar is equipped with One linkage hole 25, a coupled axle-pin 26 is arranged on the outer capping 24 of third sealing element 16, and coupled axle-pin 26 is plugged on linkage hole In 25, realize that the linkage of third sealing element 16 and interlocking bar can also reach so that the first sealing element in this manner 1 and third sealing element 16 rotate synchronously purpose, alternatively, the lower end of interlocking bar is just directly connected in third sealing element 16 On outer capping 24, in this case, removable point of the first linkage element 20 and third sealing element 16 cannot be realized From and combine, but will not influence the present apparatus collect sample function.

Either above-mentioned any implementation, interlocking bar can all pass through the first chamber 1 and connect 10 He of the first sealing element Third sealing element 16.Also, interlocking bar or thereon for the part shape that needs to have certain of connection, usually this Kind of shape is not circular, be can be such as rectangular, semicircle or triangle, correspondingly, the first sealing element 10 and the Interior outer shaft hole on three sealing elements 16 is also same shape, then, just pass through this shape between interlocking bar and interior outer shaft hole Shape carries out circumferential limit, will not relatively rotate, and such interlocking bar can drive first sealing element by two axis holes It is rotated with third sealing element, to realize linkage.In other possible modes, interlocking bar and interior outer shaft hole can also To be the circular hole of close-fitting, the power to link at this time is adjacent to the frictional force between face from interlocking bar and interior outer shaft hole.At other In possible mode, interlocking bar and axis hole are also possible to the step-type relationship that is linked, this step-type pass that is linked Under system, interlocking bar or interior outer shaft hole can independently rotate certain angle, then resynchronisation rotation.

Correspondingly, linkage hole 25 and coupled axle-pin 26 can also use under the fit system of linkage hole 25 and coupled axle-pin 26 Above-mentioned similar shape is linked to realize, or is linked using similar principle to realize.

As another way of realization being linked, interlocking bar is equipped with axis hole, the first sealing element or third sealing Element is equipped with the co-operating member to link with interior outer shaft hole, and co-operating member is of similar shape with axis hole, this shape is inclined It from interlocking bar axle center, or is non-round, so that interlocking bar and co-operating member can be realized linkage.Some excellent In the mode of choosing, interlocking bar can also with co-operating member is step-type is linked.

Second linkage element 21 can directly link the first sealing element 10 and the second sealing element 11, can also link Two sealing elements 11 and third sealing element 16 and whose linkage are not the specific implementation of the invention to be limited, the present invention Purpose be able to realize three sealing priority.The appearance as shown in Fig. 2,7,8, the second linkage element 21 are linkage The short object of pin or analogous shape, the second linkage element 21 are connected on the upper capping 27 of the second sealing element, naturally it is also possible to Gu It is connected on the lower capping 28 of third sealing element 16 (this mode is not shown in the figure), no matter the second linkage element 21 is to be connected in Second sealing element 11 is still connected on third sealing element 16, and the second sealing element 11 and third sealing element 16 are in addition One of the hole of setting and the cooperation of the second linkage element 21 in (second linkage element 21 that is not connected that), likewise, the Two linkage elements 21 and matched hole also have certain shape, and this shape is similar with interlocking bar above-mentioned, both may be used To deviate the second sealing element or third sealing element rotation center, it is also possible to non-round such as rectangular, semicircle Or triangle etc., one of in addition the purpose is to be able to drive set bar and/or linkage one of hole to rotate with it, This rotate with it can be synchronous, be also possible to the drive of discontinuity, and this rotation can be equidirectional, be also possible to Opposite direction.

Second sealing element 11 with the first sealing element 10 when linking, with the rotation of the first sealing element 10, second Sealing element 11 can be sealed the second chamber 2 by the second helicitic texture 18, and the second sealing element 11 is close with third When sealing the linkage of element 16, since third sealing element 16 is linked with the first sealing element 10, then it is close also to will drive second Envelope element 11 is sealed the second chamber 2.The direct linkage part of second sealing element 11 is the first sealing element 10 or Three sealing elements 16 can be arranged to consider according to the structure of actual product, be selected as needed.

In some preferred modes, the linkage between the second sealing element and third sealing element, which can be, passes through fixation Connection is to realize.In some preferred modes, the linkage between the first sealing element and third sealing element, which can be, to be passed through It is fixedly connected to realize, that is to say, that as shown in figure 13, can be one between the second sealing element 11 and third sealing element 16 The connected mode of kind, is equivalent to the second sealing element 11 and third sealing element 16 is linked together, can be realized linkage naturally, this Kind is connected, and can be and is inherently linked together, such as some surface of two sealing elements is fixedly connected or sticks together, can also Being achieved a fixed connection by other components, such as connecting rod, the present invention does not limit connected mode, as long as can reach To the effect for making it link.Equally, between the first sealing element and the second sealing element, the first sealing element and third are close It seals between element, can also naturally realize linkage in this way.

In some preferred modes, the first linkage element is interlocking bar.In some preferred modes, the second linkage member Part is set bar.In some preferred modes, the linkage refers to synchronous rotation.It is described in some preferred modes Linkage refer to it is synchronous to mobile close to the direction of sample interior.In the present invention, especially seal process is synchronous, example for linkage Such as, it rotates synchronously, synchronous rotation is particularly suitable for the connection type of helicitic texture, and for another example, synchronous to be packed into, synchronous be packed into especially is fitted It for the connection type of plug, is being clamped, in the connection types such as knob, similar linkage structure can also be used.

Position limiting structure

As previously mentioned, channel 5 is a kind of way of realization at separation, effect is that 2 grafting of the second chamber can be allowed to be mounted on Wherein, it and is sealed against, then as previously mentioned, need to limit the cooperation between the second chamber 2 and channel 5, otherwise second Chamber 2 may be slid into the first chamber 1 by this channel 5, pollute or cause liquid sample at channel 5 to liquid sample It can largely leak.Therefore, mutually matched position limiting structure is set in the inner wall in channel 5 and the outer wall of the second chamber 2, this limit knot The extreme position that second chamber 2 is installed is limited to the somewhere in channel 5 by structure, after the second chamber 2 is installed in place, just will not again to Inside continue to move to.

As shown in Fig. 2,7,8, a between outer land terrace 36 is set on the inner wall in channel 5, step surface 36 is as boundary in addition Line, channel 5 is bigger than the internal diameter close to this external a part close to the internal diameter of this part of the first chamber 1, at the same time, such as Shown in Fig. 5-6, on the outer wall of the second chamber 2 be arranged one with this between outer land terrace 36 cooperate interior step surface 29, within step Face 29 is used as line of demarcation, the second chamber 2 close to this part of the first chamber 1 internal diameter than close to internal diameter of this external a part It is small, then interior step surface 29 and between outer land terrace 36, which carry out cooperation, to limit the limit installation site of the second chamber 2 at this It in chalaza, when the second chamber 2 is packed into, due to step surface card master, inwardly can not further move, realize the limit to the second chamber 2 Position.

Channel 5 is that the first chamber 1 and the second chamber 2 is allow to realize the structure of assembly, and channel 5 can regard the first chamber 1 as A part, ideal state are, after the second chamber 2 completes installation, the gabarit (such as bottom surface) of the second chamber 2 is outer without departing from channel 5 Surface, such case can make the first chamber 1 and the second chamber 2 use one entirety of preceding formation, but if when using still Such case, the second chamber 2 will be difficult to take out out of first chamber 1, and therefore, linkage structure of the invention can also be realized when sealing Element sealing the first chamber 1, the second chamber 2 and during channel 5, can the gradually ejection outward by the second chamber 2, when all close Envelope process is (including the first sealing element 10 to the sealing of the first chamber 1, the second sealing element 11 to the sealing of the second chamber 2 and Sealing of three sealing elements 16 to channel 5) when completing, a part of the second chamber 2 stretches out in (such as Fig. 2 except the gabarit of the first chamber 1 It is shown), the second chamber 2 can be separated from the first chamber 1 by this part of stretching at this time, after the sealing of the second sealing element 11 The second chamber 2 be one completed sealing cavity, in liquid sample can be used for secondary-confirmation detection, the second chamber 2 It, can be by independent transport to secondary detection mechanism after being detached from the first chamber 1.

In order to realize the second chamber 2 as seal process is gradually pushed out, the length of helicitic texture and the length of linkage element Need to meet certain requirement, for example, as previously described, being sealed first by the second sealing element 11 in the second chamber 2, then immediately Channel 5 sealed by third sealing element 16, during the two is sealed, the first sealing element 11 always in sealing The process of first chamber 1, ideal state are, while the first sealing element 11 completes sealing, third sealing element page 16 is just Sealing is completed, in this case, the length of the first helicitic texture 17 is equal to the second helicitic texture 18 and third helicitic texture 19 The sum of length, the length of interlocking bar meets: when the first sealing element 1 is swung down to the second sealing element 11 just by second When chamber 2 is fully sealed, the second chamber 2 and the relative position in channel 5 are constant, when third sealing element 16 starts sealed passage 5, the Two chambers 2 start to be pushed out outward.That is, the first sealing element 11 passes through interlocking bar drive the in the initial stage that lid closes Two sealing elements and the rotation of third sealing element, third sealing element is not the state in idle running at this time, not and other component Contact, and the second sealing element has begun in the helicitic texture cooperation on the second chamber 2, after the completion of the sealing of the second chamber 2, continues The first sealing element 11 is rotated, the first helicitic texture 17 continues to close up at this time, pushes down on third sealing element by interlocking bar With the second chamber after sealing, while the beginning of the second chamber 2 is displaced outwardly along channel 5, third sealing element starts sealed passage 5, until channel 5 is fully sealed, the first chamber 1 is also sealed just and is completed by the first sealing element 11 at this time.

Due to that can not be fully sealed between the second sealing element 11 and third sealing element 16, will necessarily have certain Gap 30, this partial gap may enter liquid sample when the second sealing element 11 seals the second chamber, therefore, ideal State be that after the second sealing element 11 completes sealing, third sealing element 16 still can dally a small distance, will be in gap Liquid extrude, then channel 5 is sealed again, such that residual liquid sample is as few as possible in gap, is subtracted The leakage of liquid sample when separating less, in this case, the length of the first helicitic texture 17 is just needed slightly larger than the second screw thread The sum of structure 18 and the length of third helicitic texture 19, in practice, specific size can according to need to adjust, institute of the present invention The main technical solution to be realized is, the interaction relation of sealing and the sequence of sealing.

Barrier element

In addition to the foregoing structure, carrying out the initial survey of sample using the device of the invention is also one aspect of the present invention, So, the present invention is in the state of ideal, it is desirable to can complete in sample collection, be used for two in the second chamber 2 especially After the liquid sample collection of secondary confirmation detection is completed and sealed, initial detecting, the detection sample of such secondary-confirmation are carried out It will not be contaminated because of initial detecting, it is ensured that the accuracy of secondary detection, for this purpose, also a kind of barrier element 31 of the present invention, as before Described, the effect of barrier element is temporarily by testing element and the liquid sample being collected into initial detecting chamber (i.e. the first chamber 1) Partition, temporarily prevents liquid sample from entering detection zone 3, and certainly, barrier element can also discharge sample, therefore, resistance Every the component that element is for obstructing or opening the connected relation between the first chamber 1 and detection zone 3, the initial of sample is being collected When state, barrier element 31 separates the first chamber 1 with test zone 3, and liquid sample cannot be introduced into detection zone 3 at this time, test Element will not be in contact or react with liquid sample, when collect to a certain extent or at certain opportunity, barrier element 31 The detection entrance 32 for opening 1 communication with detection region 3 of the first chamber allows a part of liquid sample to enter detection from detection entrance 31 In region 3, and initial survey is carried out by testing element, obtains a preliminary testing result.

As in Figure 2-4, barrier element 31 can be one and can rotate around the rotatable lamella of the axis rotation of the first chamber 1 A baffle 33 can be set on piece, and using preceding and collection sample original state, baffle 33 can block entrance 32, this Even if when liquid sample enter in the first chamber 1 and the second chamber 2, it is also not possible to enter in detection zone 3, will not with test member Part is in contact, and then barrier element 31 can be during sealing element rotates, on suitable opportunity and one of those Sealing element interferes, to open entrance 32, the liquid sample of initial survey is allowed to enter in detection zone 3, carries out initial survey.

For example, barrier element 31 and the linkage of the second sealing element, complete the sealing to the second chamber in the second sealing element Meanwhile the entrance that barrier element opens communication with detection region is touched, the sealing to the second chamber is completed at this time, it is ensured that second is intracavitary Liquid sample will not have any contact with the sample in detection zone, guarantee the accuracy of secondary detection.

Alternatively, appearance as in Figure 2-4, barrier element 31 is set in the periphery in channel 5, and can rotate around it, third Sealing element 16 is equipped with protrusion 34, protrusion 34 when third sealing element 16 and channel 5 seal, can drop to In the height that baffle 33 is interfered, while third sealing element 16 completes the sealing to channel 5, protrusion 34 and baffle 33 are sent out Raw interference, pushes baffle 33 that barrier element 31 is driven to rotate, and opens the entrance 32 in communication with detection region, due to sealing member in third During at part hermetic separation, the second sealing element has completed the sealing to the second chamber, therefore, when third sealing element is complete When sealing at pairs of separation, the sealing of the second chamber is formerly completed, therefore, opens the entrance of detection zone, the second chamber at this time Interior liquid sample will not have any contact with the sample in detection zone, can guarantee the accuracy of secondary detection.

In some preferred modes, barrier element is used to open the detection zone detected to initial detecting sample, When the second chamber does not collect sample or when collecting sample, detection zone is closed, when the collection of the second chamber is completed and is sealed, sample Originally it is able to enter detection zone.

In some preferred modes, including the second sealing element for sealing the second chamber, the second sealing element can Detection entrance is opened or closed, when the second sealing element completes the sealing to the second chamber, opens detection entrance.Some preferred Mode in, the second sealing element and barrier element link, while the second sealing element completes the sealing to the second chamber, touching Dynamic barrier element opens the entrance in communication with detection region.

In some preferred modes, the first chamber can be with detection zone fluid connection or partition.When detection entrance is opened When, the first chamber and detection zone realize fluid connection, and when detection entrance is closed, the first chamber and detection zone are separated.? In some preferred modes, the first sealing element and the second sealing element link, and the first sealing element can open or close inspection Entrance is surveyed, when the second sealing element completes the sealing to the second chamber, the first sealing element is driven to open detection entrance.Some In preferred mode, the first sealing element and barrier element link, and complete the same of the sealing to the second chamber in the second sealing element When, the entrance that barrier element opens communication with detection region is touched by the first sealing element.

In some preferred modes, third sealing element and the second sealing element link, and third sealing element can be beaten Detection entrance is closed on or off, when the second sealing element completes the sealing to the second chamber, third sealing element is driven to open detection Entrance.In some preferred modes, third sealing element and barrier element link, and complete in the second sealing element to the second chamber Sealing while, pass through third sealing element touch barrier element open communication with detection region entrance.
