Description

Chamber for liquid substance testing

[0001] The present invention relates to a chamber for testing liquid substances, and more particularly, to a chamber for testing liquid substances that can collect a liquid substance sample to be tested in an optimal state, thereby improving the accuracy and ease of testing liquid substances.

[0002] First, the term "liquid substance" in the following is defined to include all types of bodily fluids contained in the human body, such as saliva, blood, semen, sweat, urine, and tears, and more broadly to include various types of similar liquid substances, including organic and inorganic compounds used in scientific research, such as medicine, bio, water quality, and the environment.

[0003] Nowadays, people use liquid substances to check their health and physical condition, either through professional medical institutions or through self-testing devices. The use of simple test devices, which have been around since the past, remains constant, and younger generations are steadily increasing their use due to their ease of use, short turnaround time and cost, and quick results.

[0004] Testing devices for assessing an individual's health or physical condition primarily utilize liquid substances, such as saliva, blood, semen, urine, tears, and sweat. They detect hormones contained in these fluids or monitor changes in their condition. Representative testing devices include those for pregnancy tests, diabetes tests, and blood sugar measurements. Furthermore, testing devices for liquid substances containing organic and inorganic compounds are being developed and used in fields such as medicine, biotechnology, water quality analysis, and the environment.

[0005] However, in the case of the sampling means used in conventional testing machines, it is difficult to accurately control the amount of liquid substance to be measured, and it is difficult to efficiently contain the liquid substance sample in an optimal state, so there is a difficulty in that the accuracy is somewhat low when performing a liquid substance test using the testing machine.

[0006] Meanwhile, recent electronic testing equipment has become more versatile, enabling testing of a wider range of items than before. However, the sheer number of electronic testing equipment makes it difficult to select a sample chamber designed specifically for each tester. Furthermore, operation of the testing equipment is often cumbersome, necessitating the development of solutions to address these issues.

[0007] The problem to be solved by the present invention is to provide a chamber for testing a liquid substance that collects a liquid substance sample to be tested in an optimal state and facilitates insertion and removal into a testing device.

[0008] According to an embodiment of the present invention for solving the above-described problem, a chamber for testing a liquid substance comprises: a chamber sheet including a sheet body, an injection groove formed in a longitudinal direction on the sheet body, and an air exhaust port; and a chamber plate including a handle portion and an insertion portion extending in the longitudinal direction from the handle portion, wherein a fastening space into which the chamber sheet is inserted and fastened is formed in a sunken shape in the insertion portion, and a sample portion formed in the fastening space into which a liquid substance sample is injected and supported, wherein the sample portion may include an injection ramp formed to have an end near the handle portion having a set height and a slope whose height decreases as it goes in the longitudinal direction, at least a portion of which is inserted into the injection groove; a support region formed to extend in the longitudinal direction on the injection ramp and support the body fluid sample, and an observation region formed within the support region and through which the liquid substance sample is observed through a lens of a tester.

[0009] A chamber for examining a liquid substance according to an embodiment of the present invention may further include a double-sided tape that is adhered to the back surface of the chamber sheet, and when the chamber sheet is inserted into the fastening space and fastened, is adhered to the bottom surface of the fastening space, but is not adhered to the sample portion, so that a set space is formed between the holding area and the chamber sheet.

[0010] The above double-sided tape can surround the outer edges of the three directions except the outer edges of the support area connected to the injection slope.

[0011] The chamber sheet is formed with at least two fastening holes, and at least two fastening rods corresponding to the fastening holes are formed in the fastening space of the chamber plate, and the fastening rods are inserted through the fastening holes and their ends can be exposed to the outside of the fastening holes.

[0012] The above fastening rod may be pressed by the outside to spread out to a larger diameter than the fastening hole when the chamber sheet is fastened to the fastening space.

[0013] The above sample section may further include a support confirmation area connected to the support area through a microchannel to supply a liquid material sample and having a color-changing material that changes color with respect to the liquid material sample.

[0014] The above handle portion can be exposed to the outside of the tester while the chamber for testing liquid substances is inserted into the tester and connected to it.

[0015] The chamber plate has a guide protrusion that protrudes in the longitudinal direction by a set length and a guide groove that is sunken in the longitudinal direction by a set length, without encroaching on the fastening space on the upper surface of the insertion portion, and the guide protrusion and the guide groove can have a reverse insertion prevention function.

[0016] A fastening confirmation part may be formed on the back surface of the chamber plate in a set shape, and when the chamber for testing liquid substances is fully inserted into the tester, it is fastened to a groove formed in the entrance of the tester, allowing the user to visually confirm completion of fastening.

[0017] The chamber plate has a cutting surface cut from the side and back by a set length from the first end of the insertion portion, and the cutting surface may be formed in the same shape on each of the two side surfaces of the insertion portion and may be formed to have the widest width near the first end and gradually narrow in width.

[0018] The insertion portion may have a stopper formed at the first end to prevent the chamber from being inserted any further when it is fully inserted into the tester.

[0019] The above stopper has a groove shape formed from the first end toward the fastening space, and the width of the inner groove is made narrowest to form a set length in the X-axis direction, and thereafter, the width of the groove gradually increases and the width of the groove becomes narrower again near the first end, so that a sound can be generated when the chamber is fully inserted into the tester.

[0020] The above double-sided tape may have at least one color other than white.

[0021] The liquid substance testing chamber of the present invention and the testing device using the same have the effect of collecting a liquid substance sample to be tested in an appropriate amount and in an optimal state and facilitating insertion and removal into the testing device.

[0036] Hereinafter, the present invention will be described with reference to the attached drawings.

[0037] FIG. 1 is a side perspective view of a chamber for testing a liquid substance according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of a chamber for testing a liquid substance according to an embodiment of the present invention.

[0038] Referring to FIGS. 1 and 2, a chamber (1000) for examining a liquid substance according to an embodiment of the present invention may include a chamber plate (100) and a chamber sheet (200).

[0039] The chamber plate (100) may include a handle portion (110) and an insert portion (120) extending from the handle portion (110) in the x-axis direction, i.e., in the longitudinal direction.

[0040] In the insertion portion (120), a fastening space (130) into which the chamber sheet (200) is inserted and fastened is formed in the longitudinal direction, i.e., the X-axis direction, and the fastening space (130) is formed in the shape of a groove having a set depth. At this time, the set depth of the fastening space (130) is preferably a depth that makes the upper surface of the chamber plate (100) and the upper surface of the chamber sheet (200) level with each other when the chamber sheet (200) is inserted into the fastening space (130). The overall shape of the insertion portion (120) has the same shape as that of the chamber sheet (200).

[0041] In the fastening space (130), a holding region (140) into which a liquid material sample is injected and held is formed in the longitudinal direction. That is, an injection slope (141) of the holding region (140) is formed in the longitudinal direction, and a holding region (142, see FIG. 5) is formed by extending in the longitudinal direction of the injection slope (141). Here, the formation of the holding region (140) in the longitudinal direction means that the liquid material sample is supplied to the injection slope (141) in the longitudinal direction.

[0042] The handle portion (110) has a width greater than the width (length in the Y-axis direction) of the insertion portion (120), and allows the user to push it into the tester (2000) and pull it out of the tester (2000), and at least one anti-slip protrusion (111) may be formed to prevent the user's hand from slipping. At least one anti-slip protrusion (111) may be formed in the Y-axis direction, which is perpendicular to the longitudinal direction.

[0043] In FIGS. 1 and 2, the handle portion (110) is depicted as circular, but the handle portion (110) may be manufactured in various shapes. Referring to FIG. 8, when the chamber plate (100) is inserted into the tester (2000), the handle portion (110) is not inserted into the tester (2000) but is located outside, so that the user can easily hold it by hand.

[0044] The chamber plate (100) can be partially inserted into a liquid substance testing device (2000, see FIG. 8) while holding a liquid substance sample, thereby providing the liquid substance sample to the tester (2000).

[0045] The chamber plate (100) can be formed of a wide range of materials that can be used to form a chamber for testing liquid substances that can be commonly used in test equipment in the relevant technical field, but can preferably be formed of a light-transmitting material that transmits light.

[0046] The light-transmitting material may be any material commonly used in the relevant technical field to form the base substrate. Furthermore, transparent materials may be used to enhance light transmittance and obtain a clear observation image. For example, the light-transmitting material may be formed from any one of transparent synthetic resins such as polycarbonate, polyethylene, and acrylic, natural rubber, and glass, but is not limited thereto.

[0047] The chamber sheet (200) may include a sheet body (210), a fastening hole (220), an injection groove (230), and an air outlet (240).

[0048] The sheet body (210) has the same shape as the fastening space (130). When the sheet body (210) has at least one vertex, each vertex may be chamfered and manufactured in a curved shape so that it can be easily inserted into the fastening space (130).

[0049] The fastening space (130) and the sheet body (210) may be configured such that at least one of the edges or vertices is deformed in shape (shape). In this case, if the upper surface of the sheet body (210) is exposed and each component (220, 230) is correctly arranged and fastened to the fastening space (130), fastening is performed. If the back surface of the sheet body (210) is exposed and fastened to the fastening space (130), fastening is not performed. Referring to FIGS. 1 and 2, the fastening space (130) and the sheet body (210) are manufactured in a square shape, and one vertex of the square is manufactured in a diagonally cut shape. Therefore, fastening is possible only when the upper surface of the sheet body (210) is exposed and inserted in a direction matching the arrangement of each component of the sample portion (140).

[0050] The fastening hole (220) is composed of at least two or more, and is a hole into which a fastening rod (131) formed in a fastening space (130) is inserted. The fastening hole (220) and the fastening rod (131) can be omitted when the chamber sheet (200) is fitted into the fastening space (130) by means of a screw connection, laser welding, welding, or tape adhesion. Each fastening rod (131) is inserted into each of the plurality of fastening holes (220), and a part of the end of the fastening rod (131) is exposed to the outside of the fastening hole (220), and the exposed part of each fastening rod (131) is pressed by the equipment, thereby spreading out to be larger than the diameter of the fastening hole (220), so that the chamber sheet (200) does not come off from the chamber plate (100) even by an external force.

[0051] The injection groove (230) is a hole that allows a liquid material sample to be provided to the injection ramp (141) of the sample section (140) when the chamber sheet (200) is inserted and fastened into the fastening space (130), and is formed to fit the shape of the injection ramp (141). At least a portion of the injection ramp (141) can be inserted into the injection groove (230) when the chamber sheet (200) is inserted and fastened into the fastening space (130). Preferably, a protruding portion of the injection ramp (141) can be inserted while being fitted into the injection groove (230).

[0052] The air exhaust port (240) is a hole that discharges air within the holding area (142), and through this, external air that may unintentionally enter the holding area (142) and interfere with observation and analysis of the liquid material sample can be discharged, thereby having the effect of further improving the accuracy of the liquid material inspection.

[0053] Meanwhile, the way in which the chamber sheet (200) is fastened to the fastening space (130) can be achieved by various conventional methods in addition to the above-described fastening method, including physical fastening.

[0054] The chamber sheet (200) can be formed of a wide range of materials that can be used to form a chamber for testing liquid substances that can be commonly used in a tester in the relevant technical field, but can preferably be formed of a light-transmitting material that transmits the same light as the chamber plate (100).

[0055] FIG. 3 is a drawing for explaining a sample section according to an embodiment of the present invention. Referring to FIG. 3, the sample section (140) is a space where a liquid substance to be tested is applied, and serves to hold a liquid substance sample to be tested so that the camera lens of the tester (2000) can capture the liquid substance.

[0056] The sample section (140) is formed within the fastening space (130) of the insertion section (120) and can easily accommodate a liquid material sample. The sample section (140) may include an injection slope (141), a loading area (142), and an observation area (143). In some cases, the sample section (140) may further include a loading confirmation area (144).

[0057] The injection ramp (141) is formed in the longitudinal direction of the chamber plate (100) to facilitate the injection of a liquid material sample. The injection ramp (141) may be formed to have an inclined surface with a set height at one end closer to the handle portion (110) and a height that decreases as it goes in the longitudinal direction. Accordingly, the liquid material sample is first injected into the highest end of the injection ramp (141) and flows along the inclined surface in the longitudinal direction.

[0058] The holding area (142) extends longitudinally along the injection ramp (141) and holds the liquid material sample supplied along the inclined surface of the injection ramp (141). The holding area (142) is formed flat so that the liquid material sample is evenly distributed. In some cases, the holding area (142) may be formed by digging to a set depth, or a protective wall of a set height may be formed along the outer boundary.

[0059] The observation area (143) is an area where the liquid material sample supplied to the holding area (142) is collected, and is an area where the liquid material sample is observed through the lens of the tester (2000). The area of ​​the observation area (143) is preferably formed in a square shape, but may be configured in various shapes. The observation area (143) may be formed in a sunken shape in the bottom surface of the sample portion (140). The observation area (143) is preferably formed near the center of the holding area (142), but the formation location may vary depending on the case.

[0060] In this way, by forming the injection slope (141) and the holding area (142) in the same direction as the longitudinal direction of the chamber plate (100), the liquid material sample can be injected more easily into the sample section (140), and the liquid material sample can be provided in an appropriate amount and in an optimal condition, thereby improving the accuracy and ease of liquid material inspection.

[0061] Each component (141 to 143) of the sample section (140) can be made of a wide range of materials that are commonly used in testing machines in the relevant technical field and can easily hold and observe liquid material samples, but can preferably be formed of a light-transmitting material that transmits light.

[0062] Additionally, each component (141 to 143) of the sample section (140) may be formed of the same material as the chamber plate (100) or may be formed of a different material.

[0063] The loading confirmation area (144) may be formed within the loading area (142) or may be formed outside the loading area (142). If formed outside the loading area (142), it may be connected to the loading area (142) by a microchannel. The loading confirmation area (144) includes a color-changing material that changes color in response to a liquid substance sample, and the color-changing material may be litmus paper, etc.

[0064] The loading confirmation area (144) is intended to enable the user to visually confirm whether the liquid substance sample has been properly supplied through the discoloration material after the liquid substance sample has been injected into the sample section (140). Accordingly, if the loading confirmation area (144) is formed, the loading confirmation area (144) should be kept open and not sealed.

[0065] FIG. 4 is a perspective view of a chamber sheet according to an embodiment of the present invention, wherein (a) is a perspective view showing the back surface of the chamber sheet (200), and (b) is an exploded perspective view of the back surface of the chamber sheet (200).

[0066] Referring to FIG. 4, the chamber sheet (200) may have a double-sided tape (250) attached to the back surface. The double-sided tape (250) is adhered to the back surface of the chamber sheet (200) in a shape that exposes each fastening hole (220), an injection groove (230), an air exhaust port (240), and the space between the air exhaust port (240) and the injection groove (230). That is, the double-sided tape (250) is adhered to the remaining area of ​​the back surface of the chamber sheet (200) except for each fastening hole (220), an injection groove (230), an air exhaust port (240), and the space between the air exhaust port (240) and the injection groove (230). If the loading confirmation area (144) is configured, the double-sided tape (250) will be manufactured in a shape that exposes the corresponding area of ​​the chamber sheet (200) corresponding to the loading confirmation area (144).

[0067] The double-sided tape (250) will be adhered to the bottom surface of the fastening space (130) when the chamber sheet (200) is inserted into the fastening space (130) and fastened. For example, the double-sided tape (250) will be adhered to the bottom surface of the remaining area of ​​the bottom surface of the fastening space (130) excluding the area where the fastening hole (220), the holding area (142), and the injection slope (141) are formed.

[0068] The double-sided tape (250) is manufactured to have a color so that the injection groove (230) stands out in the user's view. The color may be at least one color other than white. Preferably, the color of the double-sided tape (250) is black, but may also be one of red, yellow, blue, etc.

[0069] Meanwhile, the gap between the holding area (142) and the chamber sheet (200) can be formed thin enough to evenly distribute the liquid substance sample to be examined so that the liquid substance sample can be easily observed, and can be determined in various ways depending on the liquid substance to be examined. Specifically, the gap between the holding area (142) and the chamber sheet (200) can be determined depending on the average size (average diameter) of the measurement object contained in the liquid substance to be examined.

[0070] For example, when measuring sperm contained in semen, since the average diameter of the sperm head is about 5 to 8 μm, there is an advantage in that the gap between the retention area (142) and the chamber sheet (200) is 10 μm or less, which can prevent multiple sperm from piling up in multiple layers. In this case, the sperm contained in the semen can be evenly distributed in a single layer, which has the effect of making it easy to observe and analyze the sperm contained in the semen sample. As another example, when measuring white blood cells having an average diameter of 16 to 20 μm, it may be advantageous if the gap between the retention area (142) and the chamber sheet (200) is 30 μm or less.

[0071] In this way, the gap between the holding area (142) and the chamber sheet (200) can be determined according to the size of the measurement target, but is preferably less than 50 μm. More preferably, it can be less than 30 μm, even more preferably, it can be less than 20 μm, and most preferably, it can be less than 10 μm.

[0072] Meanwhile, the gap between the holding area (142) and the chamber sheet (200) is determined by the thickness of the double-sided tape (250). The gap between the holding area (142) and the chamber sheet (200) will be described with reference to Fig. 5. Fig. 5 is a longitudinal cross-sectional view of a chamber according to an embodiment of the present invention.

[0073] As described above, the chamber sheet (200) is inserted and fastened so that the double-sided tape (250) adhered to the back surface is adhered to the bottom surface of the fastening space (130), and the area of ​​the chamber sheet (200) where the double-sided tape (250) is not adhered is located on the injection slope (141), the holding area (142), and the holding confirmation area (144). That is, the double-sided tape (250) is not adhered to the injection slope (141), the holding area (142), and the holding confirmation area (144).

[0074] Accordingly, a space equal to the thickness of the double-sided tape (250) is formed in the area of ​​the holding area (142) because the double-sided tape (250) is not adhered. That is, a space equal to the thickness of the double-sided tape (250) is formed between the holding area (142) and the sheet body (210) of the chamber sheet (200).

[0075] And since the double-sided tape (250) is adhered to the bottom surface except for the holding area (142), it surrounds the outer surface of the holding area (142). Specifically, the double-sided tape (250) surrounds the outer surface in the remaining three directions except for the outer surface of the holding area connected to the injection slope (141). As a result, the liquid material sample contained in the holding area (142) is blocked by the double-sided tape (250) and does not escape to the outside.

[0076] Fig. 6 is a top perspective view of a chamber plate according to an embodiment of the present invention. Referring to Fig. 6, the upper surface of the insertion portion (120) of the chamber plate (100) may have a guide protrusion (121) that protrudes in the longitudinal direction by a set length without encroaching on the fastening space (130) and a guide groove (122) that is recessed in the longitudinal direction by a set length.

[0077] The guide protrusion (121) is seated in a fastening groove (not shown) formed inside the tester (2000), and the guide groove (122) is inserted into a protrusion formed inside the tester (2000). Accordingly, the guide groove (122) guides the insertion path so that the plate (100) is inserted naturally without being misdirected when inserted into the tester (2000).

[0078] The guide protrusion (121) and the guide groove (122) are formed to be spaced apart from each other and are formed so as not to encroach on the fastening space (130). For example, the guide protrusion (121) is formed from the first end of the insertion portion (120) that is first inserted into the tester (2000) toward the handle portion (110) in the longitudinal direction by a set length. In addition, the guide groove (122) is formed from the first end toward the handle portion (110) in the longitudinal direction by a set length.

[0079] The set lengths of the guide protrusion (121) and the guide groove (122) may be the same or different. In cases where the set lengths are different, as shown in FIG. 6, the set length of the guide groove (122) may be longer than the set length of the guide protrusion (121), but in some cases, the set length of the guide protrusion (121) may be longer than the set length of the guide groove (122).

[0080] These guide protrusions (121) and guide grooves (122) have the function of allowing the user to easily insert the chamber (1000) into the tester (2000), but can also have the function of preventing reverse insertion by preventing the chamber (1000) from being inserted into the tester (2000) when the user inserts the chamber (1000) with the back surface facing upward.

[0081] Meanwhile, a stopper (123) may be formed at the first end of the insertion portion (120) of the chamber plate (100) to prevent the chamber (1000) from being inserted any further when it is fully inserted into the tester (2000). The stopper (123) may be manufactured in the form of a groove formed from the first end toward the fastening space (130). For example, the stopper (123) may be manufactured in a form in which the width of the inner groove (length in the Y-axis direction) is made narrowest to a set length in the X-axis direction, and then the width of the groove gradually increases and becomes narrower again near the first end. When the stopper (123) has the form described above, a "click" sound is generated when the chamber (1000) is fully inserted into the tester (2000), so that the user can confirm by sound that the chamber (1000) is fully inserted.

[0082] Fig. 7 is a rear perspective view of a chamber plate according to an embodiment of the present invention. Referring to Fig. 7, the chamber plate (100) may have a cutting surface (C1) cut from the side and back surface by a set length from the first end of the insertion portion (120). The cutting surface (C1) may be formed in the same shape on each of the two side surfaces of the insertion portion (120), and may be formed such that the width is widest near the first end and gradually narrows.

[0083] These two cutting surfaces (C1) prevent the back surface on which the cutting surfaces (C1) are formed from touching the bottom surface of the insertion passage of the tester (2000) when the chamber (1000) is inserted into the tester (2000), and the back surface on which the cutting surfaces (C1) are not formed touches the bottom surface of the insertion passage of the tester (2000), thereby allowing the user to insert the chamber (1000) naturally without exerting force.

[0084] Meanwhile, a triangularly protruding fastening confirmation portion (150) may be formed on the back surface of the chamber plate (100). The fastening confirmation portion (150) is exposed to the outside of the tester (2000) when the chamber (1000) is completely inserted by the stopper (123). Accordingly, the user can visually check the connection state between the fastening confirmation portion (150) and the tester (2000) to confirm completion of fastening. In addition, the fastening confirmation portion (150) may have a reverse insertion prevention function that prevents the chamber (1000) from being completely inserted into the tester (2000) when the user turns the chamber (1000) over and inserts it into the tester (2000). Meanwhile, the fastening confirmation portion (150) may be manufactured in a shape other than a triangle.

[0085] FIG. 8 is a front view showing a state in which a liquid substance inspection chamber according to an embodiment of the present invention is attached to a tester, and FIG. 9 is a rear view showing a state in which a liquid substance inspection chamber according to an embodiment of the present invention is attached to a tester.
