Description

Technology Field

[0001] The present invention relates to a sample chamber applied to a narcotic detection kit and an integrated inspection device equipped with the same, which can stably deliver a solid sample for narcotic detection to a narcotic detection cartridge without external leakage or scattering, and can easily and stably receive, transport, and load collected solid samples or pre-treated specimens in a sealed state, as well as easily detect and test narcotics with only a trace amount of solid sample. Background Technology

[0002] As is well known, for the detection or analysis of solid samples containing narcotics, a method is used in which the sample is collected, transferred to an external container or vial, dissolved by adding a separate solvent, and then applied to an analysis instrument or detection kit after undergoing a mixing or stirring process.

[0003] In this method, there are problems such as sample contamination or loss due to external exposure during sample transport, and particularly in the case of trace samples, there is a problem of reduced reproducibility.

[0004] Furthermore, conventional sample chambers or containers are often designed for simple storage or transport purposes, resulting in a structural separation between the sample dissolution and transport processes. Consequently, performing precise analysis after on-site screening requires the inconvenience of transferring the sample to a separate analysis cell or container, which makes it difficult to maintain sample integrity and ensure analytical reliability.

[0005] Furthermore, in the case of precision analysis equipment such as Raman spectrometers, background or fluorescence signals may be generated depending on the material and shape of the cell where the sample is located, which can affect the analysis results; however, conventional sample chambers are provided with structures that do not sufficiently consider these optical characteristics, posing a problem that makes accurate analysis difficult.

[0030] Meanwhile, the solvent capsule (10) is provided inside the front end connecting section (112) and has a soft shell, and a solvent (e.g., methanol, ethanol, acetonitrile, acetone, ethyl acetate, etc.) that is mixed with and dissolves the solid sample can be filled inside the shell.

[0031] In this solvent capsule (10), the shell is ruptured through the rupture means (143) in accordance with the operation of the drive button part (140), and the solvent filled inside leaks out of the shell and can then be mixed with a solid sample. Here, the internal shape of the front part coupling section (113) equipped with the drive button part (140) will be described later.

[0032] The sample receiving chamber (120) is provided with a cylindrical receiving space for receiving a solid sample including narcotics, and is a component coupled to the front end of the chamber body (110), and can be provided in a cylindrical shape corresponding to the cylindrical shape of the chamber body (110).

[0033] The sample receiving chamber (120) may be formed in such a way that the rear end portion protrudes outwardly so that a coupling groove (121) can be formed on the inner circumference of the rear end portion that is coupled to the front end portion of the chamber body (110), and accordingly, the coupling piece (114) of the chamber body (110) is coupled to the coupling groove (121), thereby allowing for a stable and secure coupling.

[0034] Additionally, the sample receiving chamber (120) may be formed in an open shape so that a solid sample, including narcotics, etc., can be collected through a separate collection means and received inside, and the outer circumference of the front part may be formed in a concave shape inwardly corresponding to the diameter of the rear end of the front part protection cap (130) so that the front part protection cap (130) can be attached thereto, thereby allowing the front part protection cap (130) to be stably and firmly attached to the front part.

[0035] The shear protection cap (130) is a component that is coupled to the shear portion of the sample receiving chamber (120). It is provided in a cylindrical shape in which the shear portion is closed and the rear portion is open, so that it is stably coupled to the shear portion of the sample receiving chamber (120), thereby safely protecting the solid sample contained inside the sample receiving chamber (120).

[0036] The driving button portion (140) is provided on the outer circumference of the front portion of the chamber body portion (110) and is a component that operates such that a rupture means (143) coupled inside the chamber body portion (110) can rupture the solvent capsule (10), and may include a push button (141), a return spring (142), a rupture means (143), etc. as shown in FIGS. 3 and 4.

[0037] Here, the push button (141) may be provided in a block shape such as a square or a circle, and a locking projection (112b) may be formed on the inner surface of the coupling hole (112a) of the front coupling section (112) into which the push button (141) is inserted and coupled so as not to detach the push button (141), and a locking section (112c) may be formed protruding in the central direction at the lower end of the coupling hole (112a), and a return spring (142) may be provided at the lower end of the push button (141) so that both ends are supported by the middle part of the push button (141) and the locking section (112c) to return to the original position.

[0038] Accordingly, when the push button (141) is pressed by a finger or the like and moves downward, and then the finger or the like is removed to remove the pressing pressure, it returns to its original position and is caught on the catch projection (112b) to be maintained in its original position.

[0039] Additionally, a ring-shaped hole (112d) may be formed inside the front joint section (112), and a rupture means (143) may be provided along the ring-shaped hole (112d) at the bottom of the push button (141). The rupture means (143) may be provided as a ring-shaped plate with a portion of its lower section cut off, made of an elastic plastic material, and a rupture projection (or rupture pin, 143a) may be formed protrudingly on the inner side.

[0040] Here, the ring-shaped hole (112d) is formed at an angle so as to have a narrow space at a position opposite to where the push button (141) is coupled, so that when the push button (141) is pressed and the plate portion moves in the opposite direction, it is compressed along the angled inner surface, so that the rupture projection (143a) can protrude through the through hole of the inner wall of the ring-shaped hole (112d) toward the central portion where the solvent capsule (10) is placed, and accordingly, not only is the solvent capsule (10) ruptured, but the solvent filled inside can also leak out and mix with the solid sample.

[0041] The rear end protection cap (150) is a component that is coupled to the rear end of the chamber body (110) to seal the inside and outside. It may be equipped with a rear end coupling cap (151) that is coupled to the rear end of the chamber body (110) to align the narcotic detection cartridge (200). A sealing seal member (152) may be provided inside to maintain airtightness between the inside and outside at the rear end of the chamber body (110). The rear end coupling cap (151) may be responsible for coupling between the chamber body (110) and an external analysis device, and may assist in ensuring that the chamber's internal flow path and the external device's inlet are accurately aligned when coupled. Additionally, a shape may be formed on the outer surface so that it can be easily coupled or uncoupled through rotational operation.

[0042] In addition, the sealing member (152) can be provided to maintain airtightness between the inside and outside of the chamber, thereby preventing the dissolved sample or solvent from leaking out, ensuring sealing performance at the rear end connection area of ​​the chamber, and maintaining a stable sealing state even with pressure changes during sample transfer.

[0043] These rear protection caps (150) can be provided in a shape that allows them to be fastened in a screw thread or bayonet manner at the mutually coupled portions, and can stably support the narcotic detection cartridge (200) while stably connecting the rear portion of the chamber body (110) and the external analysis device.

[0044] Here, a cartridge support ring (153) for supporting a drug detection cartridge (200) may be additionally provided, and a sealing member (152) may be provided between the cartridge support ring (153) and the rear end coupling cap (151).

[0045] As described above, the sample chamber (100) applied to the drug detection kit may be formed with an overall cylindrical shape that is easy to grip by hand, and may have an uneven surface or a ring shape that allows for rotational operation to prevent slipping during use, and the rear end of the chamber may have a screw or coupling shape so as to be coupled with an external device or analysis equipment, and the opposite front end may be coupled with a sample inlet or a protective cap.

[0046] In addition, a portion of the main body housing may be formed of a transparent material to allow inspection of the internal state, thereby enabling visual confirmation of whether a sample is contained inside or if solvent has been released.

[0047] In addition, it can be provided with a linear and symmetrical shape for mounting on a holder or stage of a Raman spectrometer or high-precision analysis equipment as well as for field use, and the internal components are structured to be separable from each other, and during assembly, they can be aligned through steps, interlocking structures, or support surfaces so as to be fixed in an accurate position inside the housing.

[0048] In addition, a space in which a sample is received and dissolved may be formed in the internal center, and this space may have a structure that is enclosed to prevent the solid sample from leaking out, and an axially extended flow path may be formed around the sample receiving space to allow the dissolved sample to move.

[0049] In addition, a capsule containing a solvent for dissolving a sample can be separately accommodated inside the chamber, and this capsule can be protected from external impact or rupture during transport and can be stably fixed at a specific location inside the chamber.

[0050] Here, the solvent capsule can be designed to remain unconnected to the sample receiving space and to be selectively ruptured by user operation, and the rupture point of the capsule is formed in a thin or structurally weak area so that it can be broken only when an intended force is applied.

[0051] The sample chamber (100) described above may include a flow path structure communicating with a sample receiving space inside, and the flow path may have a structure formed with a constant cross-sectional area and length to limit the movement of the dissolved sample to a certain amount, so that the sample can be naturally delivered in a certain quantity by the internal structure of the chamber without the user having to perform a separate quantitative operation.

[0052] In addition, the capacity of the solvent capsule contained within the chamber can be set to correspond to the volume and flow path structure of the sample receiving space, thereby allowing the concentration of the sample formed after dissolution to be maintained within a certain range.

[0053] As described above, the sample chamber (100) applied to the narcotics detection kit has the advantage of being able to handle multiple detection processes (e.g., Raman spectroscopy, high-precision analysis, etc.) with a single sample collection. Unlike conventional containers that only consider chemical resistance or are intended for simple storage and transport, it has the advantage of being able to continuously utilize a single chamber for on-site screening inspection, Raman spectroscopy-based precision analysis, and laboratory precision analysis pretreatment.

[0054] Accordingly, according to one embodiment of the present invention, a solid sample for narcotic detection can be stably delivered to a narcotic detection cartridge without external leakage or scattering, and the collected solid sample or pre-treated sample can be easily and stably received, transported, and loaded in a sealed state.

[0059] Here, the cylindrical support (230) is provided with a diameter at the front end corresponding to the central circular portion of the mesh (220), and can be formed in a slanted shape with a diameter that widens toward the rear end, and according to this shape, a sample can move inside through the mesh (220) and move through the sample inflow channel (240) formed along the slanted portion of the cylindrical support (230) to come into contact with the inner surface of a plurality of detection pads (210).

[0060] Meanwhile, a plurality of detection pads (210) are each arranged along the circumferential length direction and can be positioned so that they can be visually checked through the transparent part of the chamber body (110) of the sample chamber (100).

[0061] These multiple detection pads (210) may be configured to include a sample pad into which a sample introduced through a sample inflow channel (240) is absorbed, a conjugate pad into which labeled antibody molecules (e.g., gold nanoparticles, fluorescent particle-conjugated antibodies, etc.) are eluted together when the sample moves, a substrate membrane in which a test line in which an antibody that binds to a drug component is fixed and a control line indicating a normal operating state are formed, and an absorption pad that attracts the movement of the sample.

[0062] Accordingly, according to another embodiment of the present invention, a solid sample for narcotic detection can be stably delivered to a narcotic detection cartridge without external leakage or scattering, and the collected solid sample or pre-treated sample can be easily and stably received, transported, and loaded in a sealed state, as well as easily detecting and testing narcotics with only a trace amount of solid sample.
