Detailed Description

The structures referred to in the present invention or these terms of art used are further described below, and if not otherwise indicated, they are understood and explained by general terms commonly used in the art.

Detection of

Detection refers to assaying or testing for the presence of a substance or material, such as, but not limited to, a chemical, organic compound, inorganic compound, metabolic product, drug or drug metabolite, organic tissue or a metabolite of organic tissue, nucleic acid, protein, or polymer. In addition, detection indicates the amount of the test substance or material. Further, the assay means immunodetection, chemical detection, enzyme detection, and the like.

Sample(s)

The test device or collected sample of the present invention comprises a biological fluid (e.g., a medical fluid or a clinical sample). Liquid or liquid samples, or fluid samples, may be derived from solid or semi-solid samples, including fecal, biological tissue and food samples. The solid or semi-solid sample may be converted to a liquid sample by any suitable method, such as mixing, triturating, macerating, incubating, dissolving, or enzymatically digesting a solid sample in a suitable solution (e.g., water, phosphate solution, or other buffered solution). "biological samples" include samples derived from animals, plants and food, including, for example, urine, saliva, blood and components thereof, spinal fluid, vaginal secretions, sperm, feces, sweat, secretions, tissues, organs, tumors, cultures, cell cultures and media of tissues and organs derived from humans or animals. Preferably, the biological sample is urine and preferably, the biological sample is saliva. Food samples include food processing materials, end products, meat, cheese, wine, milk and drinking water. Plant samples include those derived from any plant, plant tissue, plant cell culture and medium. An "environmental sample" is derived from the environment (e.g., a liquid sample from a lake or other body of water, a sewage sample, a soil sample, groundwater, seawater, and a waste liquid sample). Environmental samples may also include sewage or other wastewater.

Test element

The term "test element" as used herein refers to an element that can detect whether a sample or specimen contains an analyte of interest, and the detection can be based on any technical principles, such as immunology, chemistry, electricity, optics, molecular, nucleic acid, physics, etc. The test element may be a lateral flow test strip which detects a plurality of analytes. Of course, other suitable test elements may be used with the present invention.

Various test elements may be combined and used in the present invention. One form is a test strip. Test strips for the analysis of analytes, such as drugs or metabolites indicative of a physical condition, in a sample may be in various forms, such as immunoassay or chemical assay forms. The test strip may be used in a non-competitive or competitive assay format. The test strip generally comprises a bibulous material having a sample application area, a reagent area, and a test area. The sample is added to the sample application zone and flows by capillary action to the reagent zone. In the reagent zone, the sample binds to the reagent if the analyte is present. The sample then continues to flow to the detection zone. Other reagents, such as molecules that specifically bind to the analyte, are immobilized at the detection zone. These reagents react with the analyte (if present) in the sample and bind the analyte to the zone, or to one of the reagents of the reagent zone. The label for indicating the detection signal is present in the reagent zone or in a separate label zone.

A typical non-competitive assay format is one in which a signal is generated if the sample contains the analyte and no signal is generated if the analyte is not present. In a competition method, a signal is generated if the analyte is not present in the sample and no signal is generated if the analyte is present.

The test element can be a test paper, and can be made of water-absorbing or non-water-absorbing materials. The test strip may include a variety of materials for liquid sample delivery. One of the test strips may be coated with another material, such as a nitrocellulose membrane coated with filter paper. One region of the test strip may be selected from one or more materials and another region may be selected from a different one or more materials. The test strip may be adhered to some support or hard surface for improved strength when the test strip is held in place.

The analyte is detected by a signal producing system, such as one or more enzymes that specifically react with the analyte, and one or more compositions of the signal producing system are immobilized on the analyte detection zone of the test strip by a method such as that described above for the immobilization of a specific binding substance on the test strip. The signal-producing substance can be on the sample addition zone, reagent zone, or detection zone, or the entire test strip, and the substance can be impregnated on one or more materials of the test strip. A solution containing the signal is applied to the surface of the strip or one or more materials of the strip are immersed in the solution containing the signal. The strip to which the solution containing the signal substance was added was dried.

The various regions of the test strip may be arranged as follows: the device comprises a sample adding area, a reagent area, a detection area, a control area, a sample adulteration area and a liquid sample absorption area. The control zone is located behind the detection zone. All zones may be arranged on a strip of test paper using only one material. It is also possible to use different materials for the different zones. The zones may be in direct contact with the liquid sample, or different zones may be arranged according to the direction of flow of the liquid sample, with the ends of each zone being contiguous with and overlapping the ends of the other zone. The material used can be a material with good water absorption such as filter paper, glass fiber or nitrocellulose membrane. The test strip may take other forms.

A commonly used reagent strip is a nitrocellulose membrane reagent strip, i.e., a detection area comprises a nitrocellulose membrane, and a specific binding molecule is fixed on the nitrocellulose membrane to display the detection result; and may be a cellulose acetate film, a nylon film, or the like. Such as the reagent strips or devices containing the reagent strips described in some of the following patents: US 4857453; US 5073484; US 5119831; US 5185127; US 5275785; US 5416000; US 5504013; US 5602040; US 5622871; US 5654162; US 5656503; US 5686315; US 5766961; US 5770460; US 5916815; US 5976895; US 6248598; US 6140136; US 6187269; US 6187598; US 6228660; US 6235241; US 6306642; US 6352862; US 6372515; US 6379620; and US 6403383. The test strip disclosed in the above patent documents and similar devices with test strips can be applied to the test element or the test device of the present invention for detecting an analyte, such as an analyte in a sample.

The test strips used in the present invention may be so-called Lateral flow test strips (Lateral flow test strips), and the specific structure and detection principle of these test strips are well known in the art. A typical test strip comprises a sample collection area or application area, a labeling area comprising a label pad, a detection area comprising a bibulous pad, and a bibulous area comprising the necessary chemicals to detect the presence of the analyte, such as immunological or enzymatic reagents. A commonly used detection reagent strip is a nitrocellulose membrane reagent strip, that is, a detection area comprises a nitrocellulose membrane, and a specific binding molecule is fixed on the nitrocellulose membrane to display a detection result; it may be a cellulose acetate film, a nylon film, etc., and it may also include a detection result control region downstream of the detection region, and usually, the control region and the detection region are in the form of a transverse line, which is a detection line or a control line. Such test strips are conventional, but other types of test strips that utilize capillary action for testing are also contemplated. In addition, typically, the test strip has a dry chemical reagent component, such as an immobilized antibody or other reagent, which when exposed to a liquid, flows along the test strip by capillary action, and as it flows, the dry reagent component is dissolved in the liquid, and the next zone is processed to react the dry reagent in that zone, thereby performing the necessary test. The liquid flow is mainly by capillary action. The present invention can be applied to a detecting device, or can be disposed in a detecting chamber to contact with a liquid sample, or can be used to detect whether an analyte exists or the amount of the analyte exists in the liquid sample entering the detecting chamber.

Preferably, the cap 20 is provided with a mark 23, and the mark 23 helps an operator to distinguish the screwing direction of the cap 20.

Cup body and sample bottle

Referring to fig. 2 and fig. 4 to 6, the detecting device further includes a sample bottle 30, a second cavity 31 is disposed in the sample bottle 30, the second cavity 31 may also be referred to as a liquid storage cavity, and the second cavity 31 can be communicated with the first cavity 11 for storing some samples entering the detecting cavity for secondary detection. Specifically, be located first chamber 11 downside position in cup body 10 and be equipped with third chamber 12, third chamber 12 includes the third opening, and first opening is opposite with third open-ended opening direction, and sample bottle 30 is located third chamber 12, is equipped with first hole 13 between first chamber 11 and the third chamber 12, and first hole 13 is just to second chamber 31, and the sample can enter into the sample bottle 30 in the third chamber 12 through first hole 13, keeps a kind.

In order to prevent the sample bottle 30 from being exposed to the outside and to fix the sample bottle 30, the detecting device further includes a bottom support 40, a fixing buckle 41 is disposed in the bottom support, and the fixing buckle 41 is used for fixing the sample bottle 30. Specifically, the body profile of sample bottle 30 is square, is equipped with round annular recess 32 on it, and fixed knot 41 also is equipped with four, is square distribution, is equipped with protruding strip 42 on the fixed knot 41, and sample bottle 30 is through fixed knot 41, protruding strip 42 detachable connection in collet 40.

The collet 40 is lid form, with cup body 10 detachable connection, can cover the third chamber 12 and close, including the space (third chamber 12) that the collet formed with the equipment of cup body 10 can be with the sample bottle parcel. Since the cup lid 20 is already fixed to the cup body 10, there is not enough space on the upper side of the cup body 10, and in the simplest manner, the bottom support 40 is provided on the lower portion of the cup body 10, which is why the third chamber 12 is located at the lower side of the first chamber 11. Be equipped with stuck point 43 on the collet 40, be equipped with fixed slot 14 on the cup body 10, stuck point 43 can remove along fixed slot 14, and fixed slot 14 divide into vertical section 16 and horizontal segment 15, and stuck point 43 on the collet 40 removes along vertical section 16 earlier, removes in rethread rotation enters into horizontal segment 15 after to the end, and collet 40 can not follow cup body 10 and drop under the effect of gravity this moment, realizes that the collet 40 closes with the lid of third chamber 12.

Because the bottom support 40 is to be rotated on the cup body 10, preferably, the cup body 10 and the bottom support 40 are both circular, and because the sample bottle 30 is detachably connected to the bottom support 40, the sample bottle 30 can rotate along with the rotation of the bottom support 40 in the above process. In order to ensure the stability of the fixing of the bottom support 40 on the cup body 10, two fixing grooves 14 are symmetrically arranged on the cup body 10, and correspondingly, two clamping points 43 on the bottom support 40 are arranged at intervals of one hundred eighty degrees.

Sealing element between cup body and sample bottle

The above connection mode between the cup body 10 and the sample bottle 30 enables the first cavity 11 in the cup body 10 to be always communicated with the second cavity 31 in the sample 30, that is, the sample in the first cavity 11 is always communicated with the sample in the second cavity 31, if an operator places a test element or adds some detection reagents in the first cavity 11, the sample in the second cavity 31 is inevitably affected, the sample retained in the second cavity 31 is polluted, and the sample retaining function of the sample bottle 30 is meaningless. Therefore, a sealing element is required to be disposed between the cup body 10 and the sample bottle 30 for controlling the communication relationship between the first chamber 11 and the second chamber 31, so that the first chamber 11 is communicated with the second chamber 31 when a sample is kept, and the first chamber 11 is separated from the second chamber 31 when a test is performed.

Specifically, referring to fig. 4 and fig. 6, the utility model adopts the following technical scheme: the bottle mouth 33 is provided with a groove 35, the groove 35 is located at the position of the spiral 34, the sealing element 50 is provided with a first column 51, and the sealing element 50 can be clamped into the groove 35 through the first column 51, so that the detachable connection between the sealing element 50 and the sample bottle 30 is realized, namely the detachable connection between the second cavity 31 and the sealing element 50 is realized. In order to ensure the stability of the sealing element 50 fixed on the sample bottle 30, at least two grooves 35 are provided at the position of the mouth 33 of the sample bottle 30, and correspondingly, at least two first pillars 51 are provided, the number of the grooves 35 is generally the same as that of the first pillars 51, and the two first pillars 51 are arranged on the sealing element 50 in a central symmetry manner. When the sealing member 50 is fixed on the sample bottle 30, the sealing member 50 rotates with the rotation of the sample bottle 30, and if the sample bottle 30 is fixed on the base support 40, the sample bottle 30 rotates with the rotation of the base support 40, and at this time, the sample bottle 30 and the cup body 10 rotate relatively, and the second cavity 31 and the first cavity 11 rotate relatively.

The first chamber 11 is communicated with the second chamber 31 through the first hole 13, so that the installation position of the sealing member 50 is located at the position of the first hole 13, and the sealing member 50 is provided with the second hole 52. During sample reserving, the second hole 52 is communicated with the first hole 13, and the first cavity 11 is communicated with the second cavity 31; at the time of testing, if necessary, the sealing member 50 is adjusted to make the second hole 52 not communicate with the first hole 13, and accordingly, the first chamber 11 is not communicated with (blocked from) the second chamber 31. The simplest way to adjust the sealing element 50 is to rotate the sealing element 50 to switch the states, because the above-mentioned structure (the base plate 40 and the sample bottle 30) can already realize the rotation of the sealing element 50, and the mode of rotation switching is selected, so that no new parts need to be additionally introduced, which is helpful to reduce the production cost of the whole detection device.

Since the first hole 13 cannot be located at the center of the upper inner wall of the third chamber 12 and the second hole 52 cannot be located at the center of the upper end surface of the sealing element 50 in the mode of the rotational switching state, since if the two holes are located at the center, the switching between the communicating state and the non-communicating state of the first hole 13 and the second hole 52 cannot be made when the sealing element 50 rotates, and therefore, the first hole 13 and the second hole 52 should be eccentrically disposed, referring to fig. 6 to 12, when the sealing element 50 rotates, the first hole 13 and the second hole 52 are switched between the communicating state and the non-communicating state, and when the first hole 13 and the second hole 52 communicate, the first chamber 11 and the second chamber 31 communicate; when the first orifice 13 is not in communication with the second orifice 52, the first chamber 11 is not in communication with the second chamber 31. In order to increase the communication amount between the first chamber 11 and the second chamber 31 when the two chambers are communicated, the two first holes 13 are formed in the cup body 10, and the two second holes 52 are also formed in the sealing element 50, so that when the first chamber 11 is communicated with the second chamber 31, a sample can more easily flow from the first chamber 11 to the second chamber 31.

Since the sealing member 50 is located at the interface between the cup body 10 and the sample bottle 30, a part of the sealing member 50 is in contact with the cup body 10, a part of the sealing member 50 is in contact with the sample bottle 30, and the sealing member 50 serves to communicate the first chamber 11 and the second chamber 31 and deliver the sample. In order to make the sample in the sample retention portion enter the second chamber 31 from the first chamber 11 as completely as possible, the design needs to solve the problem of sample leakage from the contact gap between the cup body 10, the sealing element 50 and the sample bottle 30. Preferably, the portion of the sealing element 50 that contacts the sample vial 30 extends into the vial mouth 33, and the underside of the sealing element 50 is contoured to prevent leakage of the sample from the vial mouth 33. Meanwhile, the contact position of the sealing element 50 and the cup body 10 is the upper wall of the third cavity 12, and in the mass production of the detecting device, for the convenience of processing the cup body 10, the upper wall of the third cavity 12 of the cup body is generally a plane, the upper side of the corresponding sealing element 50 is also a plane, and the two flat surfaces are easy to leak, and preferably, the contact side of the sealing element 50 and the cup body 10 is made of soft material, such as silica gel, so that the sample leakage at the contact position of the sealing element 50 and the upper wall of the third cavity 12 can be avoided. The side of the lower portion of the sealing member 50 contacting the sample bottle 30 is made of a hard material, and a soft material is generally not selected, because the first column 51 is disposed on the sealing member 50, the first column 51 is connected to the sealing member 50, the material of the connected portion is generally the same, and the first column 51 must be made of a hard material (rigid), so that the sealing member 50 cannot fall off from the groove 35 during the rotation of the sample bottle 30, and if the first column 51 is made of a soft material, due to the friction between the sealing member 50 and the upper wall of the third chamber 12, it is likely that the first column 51 slides off from the groove 35 during the rotation of the sample bottle 30, and the rotation of the sample bottle 30 and the non-rotation of the sealing member 50 occur. Since the first column 51 is made of a hard material and the upper portion of the sealing member 50 is made of a soft material, the first column 51 can be connected to only the lower portion of the sealing member 50, and since the materials of the connected portions are generally the same, the side of the sealing member 50 contacting the sample bottle 30 is made of a hard material. Of course, if the manufacturing cost of the sealing element 50 is not considered, on the premise of ensuring that the first column 51 is made of hard material, the contact part of the sealing element 50 with the cup body 10 and the sample bottle 30 can be made of soft material, and the shape of the first column 51 is manufactured in the production process, and then the first column 51 is put into a mold, and the remaining soft material part is processed, so that the manufacturing cost is high, and the manufacturing method is very complicated, which is not preferable. And adopt the utility model provides a sealing element 50 can directly accomplish at its upper surface subsides softwood matter part after the stereoplasm part processing is accomplished, and the process velocity is fast, manufacturing cost is also low.

The sample bottle 30 can be disassembled independently from the device, and in order to realize that the first cavity 11 in the cup body 10 can still store the sample after the sample bottle 30 is disassembled, the sample cannot be leaked due to the separation of the sealing element 50 after the sample bottle 30 is disassembled. To achieve this, the sealing element 50 is detachably connected to the cup body 10, that is, the sealing element 50 is detachably connected to the first cavity 11, and when the detecting device is assembled, the sealing element 50 is separated from the cup body 10; after the sample bottle 30 is taken out and left, the sealing member 30 is assembled with the cup body 10 for sealing the first hole 13. The utility model adopts the technical proposal that: the top of the third cavity 12 of the cup body 10 is provided with a notch 17, the sealing element 50 is provided with a second column 53, the second column 53 is perpendicular to the first column 51, the sealing element 50 is driven to rotate by rotating the bottom support 40, and the second column 53 can be clamped into the notch 17. Specifically, two second columns 53 are provided corresponding to the first columns 51, and the two second columns 53 are collinear. Meanwhile, two notches 17 are also provided, the two notches 17 are arranged in a centrosymmetric manner with the first hole 13 as the center, so that the sealing element 50 is clamped into the notches 17 through the second column 53 more stably, the notches 17 comprise limiting parts 18 and supporting parts 19, the limiting parts 18 are used for limiting the rotation of the sealing element 50, after the second column 53 collides with the limiting parts 18, the sealing element 50 cannot rotate continuously, and the supporting parts 19 play a supporting role at the moment, so that the sealing element 50 can be left in the notches 17, namely, the sealing element 50 is left in the third cavity 12. Preferably, the position-limiting part 18 is in an "L" shape, and the two notches 17 on the top of the third cavity 12 are arranged in a central symmetry manner, so as to achieve a better position-limiting effect and better connect the supporting part 19 with the cup body 10. In this case, the sealing element 50, although having two directions of rotation, is only able to be engaged in the notch 17, in particular with reference to fig. 7: when the sealing element 50 rotates around one direction, the second column 53 can be clamped into the notch 17, at the moment, the second column 53 is abutted against the notch 17, and the sealing element 50 cannot rotate along the direction any more; when the sealing element 50 is rotated in the other direction, the second leg 53 cannot snap into the recess 17.

Preferably, when the second post 53 is rotated to snap into the notch 17, the snap point 43 on the base support 40 is located in the horizontal section 15, and the sealing element 50 is already fixed on the cup body 10, in order to remove the sample bottle 30 at this time, the fixing device further comprises at least one vertical section 16, the snap point 43 on the base support 40 can be removed from the cup body 10 along the vertical section 16, and the first post 51 of the sealing element 50 slides out along the groove 35 on the mouth 33 of the sample bottle 30, and the operator removes the sample bottle 30 from the fixing buckle 41 of the base support 40, and then puts the base support 40 back on the cup body 10, i.e. the operation of removing the sample bottle 30 under the condition that the first cavity 11 is sealed is completed, and in conclusion, one fixing groove 14 comprises at least one horizontal section 15 and two vertical sections 16, and in order to control the rotation of the base support 40 and the sealing element 50, the vertical sections 16 connect two ends of the horizontal section 15, such a design can avoid the collet 40 to move excessively to lead to the second pole 53 on the sealing element 50 to collide with breach 17 and lead to breaking, and in the sealing element 50 shifted over to the breach 17 from the initial position, stuck point 43 also just moved to the other end from one end of horizontal segment 15, and in addition, after the collet 40 entered horizontal segment 15 from a vertical segment 16, collet 40 only had a rotatable direction, has made things convenient for operator's operation, need not distinguish the sealed direction (the direction of rotation) of sealing element 50 again.

Preferably, referring to fig. 5 and 6, the arc angle of the two vertical sections 16 on the cup body 10 is ninety degrees, that is, the arc angle of the horizontal section 15 is ninety degrees, which also means that the sealing element 50 can rotate ninety degrees, and ninety degrees just can satisfy the switching between the communication and the non-communication between the first hole 13 and the second hole 52, and at ninety degrees, the range that the sealing element 50 can rotate is large, and accordingly, a large space is left for opening the first hole 13 and the second hole 52, which is beneficial to improving the efficiency of the sample in the first chamber 11 entering the second chamber 31.

The following description will be given in conjunction with the detecting device provided by the present invention to provide a matched using method, firstly, the assembling of the detecting device is performed, referring to fig. 4 and 5, the sample bottle 30 is mounted on the bottom support 40 through the fixing buckle 41, then the first column 51 of the sealing element 50 is plugged onto the sample bottle 30 along the groove 35 on the sample bottle 30, referring to fig. 6, the fastening point 43 on the bottom support 40 is aligned with the pair of vertical sections 16 on the cup body 10, the bottom support 40 is mounted on the cup body 10 and moves to the bottom along the vertical sections 16, it should be noted that although the two pairs of vertical sections 16 are provided on the cup body 10, the bottom support 40 is not able to be mounted along two pairs, wherein when the fastening point 43 is mounted along the pair of vertical sections 16, the situation that the second column 53 on the sealing element 50 collides with the supporting portion 17 of the gap 19, which results in that the bottom support 40 cannot move to the bottom along the vertical sections 16, therefore, the operator needs to distinguish the vertical sections 16, when the shoe 40 has bottomed out along the vertical section 16, with reference to fig. 6-8, the first aperture 13 is now in communication with the second aperture 52, which is also the initial state of the sealing element 50 described above. Referring to fig. 9 and 10, the operator rotates the bottom bracket 40 (the rotation is positive), the clamping point 43 moves along the horizontal section 15, the bottom bracket 40 rotates the sealing element 50 through the sample bottle 30, and the size of the communication between the first hole 13 and the second hole 52 gradually decreases. Referring to fig. 11 and 12, when the clamping point 43 moves to the end of the horizontal section 15, the second column 53 of the sealing element 50 is completely clamped into the notch 19, the first hole 13 is not communicated with the second hole 52, and the sealing element 50 switches the first cavity 11 and the second cavity 31 from being communicated with each other. The operator then screws on the cup lid 20 until the first catch 21 abuts against the second catch 22, i.e. the assembly of the detection device is completed.

Referring to fig. 1 and 3, the cup cover 20 is unscrewed, a sample is added into the first chamber 11, and the cup cover 20 is closed, so that the sampling operation is realized. Rotating the shoe 40 in the reverse direction (i.e. rotating the shoe 40 in the reverse direction as described above) causes the first hole 13 and the second hole 52 to be switched from the non-communicating state to the communicating state, and the sample in the first chamber 11 enters the second chamber 31 of the sample bottle 30 through the communicating region between the first hole 13 and the second hole 52 under the action of gravity, and it should be noted that the stuck point 43 is not rotated to the end of the horizontal section 15 because the end of the horizontal section 15 is connected with the vertical section 16, and if the stuck point 43 moves to the end of the horizontal section 15, it is likely that the shoe 40 will fall with the sample bottle 30 and the sealing element 50 without holding the shoe 40 by the operator's hand, resulting in the sample being spilled. Therefore, preferably, in the reverse rotation, the rotation to the middle position of the horizontal section 15 is not continued, as shown in the state of fig. 9 and 10, and the horizontal section 15 can support the clamping point 43, so that the bottom support 40, the sample bottle 30 and the sealing element 50 can not be separated from the cup body 10. A period of rest, typically thirty seconds, is sufficient, when enough sample has entered the second chamber 31 through the communicating area between the first hole 13 and the second hole 52, the operator screws the shoe 40 to continue the forward rotation, at which point the first hole 13 and the second hole 52 are again switched from the communicating state to the non-communicating state, until the stuck point 43 moves to the end of the horizontal segment 15, and the second post 53 on the sealing element 50 is again snapped into the notch 19, at which point the first hole 13 is completely sealed by the sealing element 50. Referring to fig. 13, the base support 40 is pulled down along the vertical section 16, during which the sealing element 50 is still locked in the notch 17 by the second column 53, the original sealing element 50 is still fixed on the cup body 10, the fixing buckle 41 on the base support 40 is still in the state of fixing the sample bottle 30, the sample bottle 30 and the base support 40 are separated from the cup body 10, and the first column 51 of the sealing element 50 is separated from the groove 35 of the sample bottle 30. The operator stretches into the vacancy groove 27 through fingers to take out the bottle cap 26 in the mounting groove 24, and then the bottle cap 26 is connected with the spiral 34 of the bottle opening 33 in a spiral matching mode, so that the sample bottle 30 is sealed, the sample bottle 30 is taken out from the bottom support 40, the device is independent, and the bottom support 40 is fixed to the cup body 10, so that the sample is reserved and taken out.
