Description

Technical Field

[0001] The present invention relates to a specimen collection stick, and more particularly to a specimen collection stick capable of scraping saliva or the like in the oral cavity and nasal cavity of a subject to collect a specimen such as saliva in the oral cavity or nasal cavity of the subject for specimen collection.

Background Art

[0002] Microbiological examination is an examination for determining whether a specimen is contaminated with a pathogenic bacterium that can cause a disease. That is, it is an examination performed to establish a diagnosis, treatment, and prevention method when the cause of a disease is considered to be a microorganism. Microbiological examination is for determining whether a subject is contaminated with a pathogenic bacterium such as Escherichia coli, Salmonella typhi, Staphylococcus, Pseudomonas, etc., which can cause a disease.

[0003] Generally, for microbiological examination, a specimen is collected from the body of a subject. The collected specimen is mixed with a reagent or solution for examination, and then the presence or absence of a pathogenic bacterium is examined.

[0004] When collecting a specimen from the saliva, body fluid, or body tissue of a subject, an instrument called a specimen collection stick, brush, or swab is used. That is, the specimen is collected by inserting a specimen collection swab into the body of the subject and applying the specimen to the swab and then pulling it out.

[0005] In the case of an existing specimen collection swab, a circular collection part was formed at the end of a rod-shaped swab. A fiber layer formed by attaching fine fibers of a small size was provided on the collection part of the swab. In this way, the specimen soaks into the fiber layer formed on the collection part of the conventional swab, and the specimen is collected by pulling out the collection part of the swab from the subject.

[0006] Thus, conventional specimen collection swabs, used for collecting specimens, must be kept inserted into the patient's oral and nasal cavities for a certain period of time or longer to allow saliva and other fluids to permeate the fibrous layer, which is inconvenient for the patient. Above all, there was a problem in which some of the fibrous layer of the specimen collection swab would separate and detach from the collection area of ​​the swab, remaining in the patient's body. The retention of foreign matter such as fibrous layers in the patient's body is undoubtedly a serious medical problem. In addition, there was the problem that the amount of specimen collected using conventional swabs was often insufficient, leading to a decrease in the accuracy of the test.

[0007] Therefore, there was a need for technology that could solve these problems. [Overview of the project] [Problems that the invention aims to solve]

[0008] The objective of the present invention is to solve the aforementioned problems of the conventional methods, and to provide a sample collection stick that can increase the amount of sample collected, reduce the time required for sample collection, and prevent the problem of the fibrous portion constituting the fiber layer of a conventional swab not separating from the swab. [Means for solving the problem]

[0009] An embodiment of the present invention for achieving the above-mentioned objectives includes a support portion in the form of a rod or bar having any length, and a sample collection portion located at the front end of the support portion for collecting a sample that comes into contact with the body of a person being examined. The sample collection portion has a cylindrical shape with a storage space on the longitudinal central axis side of the sample collection portion that can accommodate the sample, and a number of sample inlets and outlets communicating with the storage space are formed on the outer surface of the sample collection portion, and the number of sample inlets and outlets are arranged in a row in the longitudinal direction of the sample collection portion.

[0010] Here, it can also be further characterized that the numerous sample entry and exit points are arranged in a first row and a second row, and the first row and the second row are formed on either side of the longitudinal central axis of the sample collection section.

[0011] Here, the sample inlets and outlets of the first row and the sample inlets and outlets of the second row are arranged alternately in the longitudinal direction of the sample collection section. The sample inlet / outlet is formed in the form of a groove where the end of the sample inlet / outlet channel is closed. This can also be considered another characteristic.

[0012] Herein, another feature may be that the inside of the sample collection section is provided with one or more partitions that spatially divide the containment space.

[0013] Here, another feature may be that the sample entry / exit channel becomes narrower or wider as the sample enters from the sample entry / exit in a direction that crosses the central axis of the sample collection section.

[0014] Here, another feature may be that the sample collection section is made of a flexible or elastic material.

[0015] Hereinafter, another feature may be that the outer circumferential surface of the support portion has a protruding connecting step or connecting projection, or a lid fastening groove, so that it can be fixedly connected to the lid of a sample container that houses the sample collection portion inside. [Effects of the Invention]

[0016] The specimen collection stick according to the present invention does not require the flocking process required in the manufacturing process of existing specimen collection swabs, thus reducing the manufacturing cost of specimen collection sticks. Furthermore, because the specimen collection stick does not have a fiber layer, there is no risk of the fiber layer coming off and remaining in the body of the person being tested, as is the case with existing specimen collection swabs, thus improving the safety of the test.

[0017] Furthermore, the sample collection stick according to the present invention increases the amount of sample collected from the body of the person being tested, and since it does not require the absorption time required for the sample to soak into the fiber layer as with conventional swabs, it reduces the time required for sample collection. Therefore, it is possible to shorten the time required for sample collection, reduce inconvenience to the person being tested during sample collection, and improve the accuracy of the test by increasing the amount of sample collected.

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those with ordinary knowledge in the technical field to which the present invention pertains can easily implement it. However, the present invention can be embodied in various different forms and is not limited to the embodiments described herein. The same reference numerals can also be used for similar parts throughout the specification.

[0024] The following describes a sample collection stick according to an embodiment of the present invention with reference to the drawings.

[0025] Figure 1 is a schematic perspective view showing a sample collection stick according to an embodiment of the present invention; Figure 2 is a schematic side view showing the sample collection portion of the sample collection stick according to an embodiment of the present invention; Figure 3 is a diagram illustrating the sample collection portion of the sample collection stick according to an embodiment of the present invention; Figure 4 is a schematic side cross-sectional view showing the sample collection portion of the sample collection stick according to an embodiment of the present invention; Figure 5 is a schematic perspective view showing a schematic side cross-section of the sample collection portion of the sample collection stick according to an embodiment of the present invention; and Figure 6 is a schematic cross-sectional view showing a cross-section perpendicular to the longitudinal direction of the sample collection portion of the sample collection stick according to an embodiment of the present invention.

[0026] First, as shown in Figure 1, the sample collection stick 10 according to an embodiment of the present invention includes a support portion 200 and a sample collection portion 300, and may further include a handle portion 100.

[0027] First, the support portion 200 has the form of a rod or bar and has an arbitrary length. The sample collection portion 300 is located on the front side of the support portion 200 and supports the sample collection portion 300. A handle portion 100 is connected to the rear side of the support portion 200. The support portion 200 supports the sample collection portion 300 so that it can enter the body of the subject.

[0028] The front side of the support section 200 and the sample collection section 300 can be made of a single material, such as a polymer or elastomer. Alternatively, the support section 200 and the sample collection section 300 can be made of different materials and joined together. Furthermore, it is entirely possible to fuse the sample collection section 300 to the front side of the support section 200.

[0029] The support unit 200 only needs to be able to support the sample collection unit 300 so that it can enter the subject's body and collect the sample, and is not limited to any particular form.

[0030] Furthermore, it is preferable that the support portion 200 be made of a polymer material that is flexible and elastic, so that it can be flexibly deformed by forces applied or transmitted from the outside, while still being able to return to its original shape.

[0031] When removing the sample collection part 300 and support part 200 of the sample collection stick 10 stored in a sample container (not shown), if a tool such as tweezers is used for removal, the tweezers must be washed beforehand. After the support part 200 of the sample collection stick 10 is grasped with the tweezers and removed from the sample container, the tweezers used must be washed again once the sample collection part 300 and support part 200 of the sample collection stick 10 are placed in the position intended by the examiner.

[0032] Thus, since the tweezers used in the process of pulling the sample collection stick out of the sample container must be washed each time, this can act as a factor that reduces the efficiency of the testing work on the sample. Therefore, the following configuration can be provided so that the sample collection part 300 and the support part 200 of the sample collection stick 10 can be pulled out of the sample container without using tweezers.

[0033] In other words, it is entirely possible to have a coupling step or coupling projection 210 formed on the outer surface of the support portion 200 so that a cover or lid of the sample container can be fixedly coupled to it.

[0034] A fixing groove or fitting step (not shown) can be provided on the inside of the cover or lid (not shown) of the sample container (not shown) so that the support portion 200 of the sample collection stick 10 can be fixed to the cover of the sample container. The support portion can be connected to the fixing groove or fitting step provided on the inside of the cover of the sample container by interlocking or connecting with the connecting step or connecting projection 210 of the support portion.

[0035] In this way, since the support part 200 can be fixed to the cover or lid of the sample container, it is preferable that the support part 200 can be easily removed from the sample container together with the lid or lid of the sample container by opening the cover or lid of the sample container, without using an instrument such as tweezers.

[0036] Figure 1 shows an exemplary form of such a connecting step or connecting projection 210, which is a ring-shaped connecting step or connecting projection 210 formed circumferentially on the outer surface of the support portion 200. As can be seen in Figure 1, it is also preferable that one or more ring-shaped connecting steps or connecting projections are provided on the outer surface of the support portion 200.

[0037] Thus, if the support part 200 can be attached to the cover of the sample container, it is preferable because it increases the ease of use.

[0038] Furthermore, the handle portion 100 is located on the rear side of the support portion 200. In other words, the rear end of the support portion 200 is connected to the handle portion 100.

[0039] The handle portion 100 is connected to the rear end of the support portion 200 and has a certain length so that it can be grasped by the inspector's hand or fingers.

[0040] The handle portion 100 is connected to the rear end of the support portion 200 and has a certain length so that it can be grasped by the inspector's hand or fingers.

[0041] As can be seen in the drawing, the handle portion 100 has the form of a rod or bar of a certain length. Such a handle portion 100 is grasped by the examiner's hand or fingers. The examiner can use the handle portion 100 to control the entry or insertion of the sample collection portion 300 into the body of the person being examined.

[0042] Therefore, the specimen collection unit 300 can be entered or inserted into the body through the oral cavity, nasal cavity, or other parts of the body of the person being examined, by the examiner's control using the handle portion 100.

[0043] As can be seen in the drawing, it is preferable that a segmental groove 120, which is like a segment, is provided between the handle portion 100 and the rear end of the support portion 200, so that the handle portion 100 and the support portion 200 can be distinguished. In other words, it is preferable that a segmental groove 120 is provided between the handle portion and the support portion so that the handle portion 100 and the support portion 200 can be separated.

[0044] When the sample collection unit 300 is withdrawn from the body of the person being tested according to the intention of the user (the examiner), the sample collection unit 300 and the support unit 200 are placed in the sample container.

[0045] Here, since there is no need to house the handle portion 100 in the sample container, it is preferable to separate the handle portion 100 from the support portion 200. Therefore, it is preferable that a segment or segment groove 120 is provided between the support portion 200 and the handle portion 100, as can be seen in the drawing, so that the support portion 200 and the handle portion 100 can be separated according to the examiner's needs.

[0046] After the support portion 200 and the handle portion 100 are separated, the support portion 200 can be attached to the cover of the sample container as described above. It is preferable that the outer circumferential surface of the support portion 200 has a protruding attachment step or attachment projection 210 or a lid fastening groove so that it can be fixedly attached to the cover or lid of the sample container that houses the sample collection portion 300 inside.

[0047] The sample collection unit 300 is the part that is inserted into or enters the body of the person being tested and comes into contact with the sample, and is the part that collects the sample. As shown in Figures 1 and 2, this sample collection unit 300 is located at the front end of the support unit 200 and collects or gathers the sample that comes into contact with the body of the person being tested.

[0048] As shown in Figures 1 to 5, the sample collection unit 300 has a cylindrical shape with a storage space 310 on the longitudinal central axis LX side of the sample collection unit 300 that can accommodate a sample, and a number of sample inlets and outlets 360R1, 360R2 communicating with the storage space 310 are formed on the outer surface of the sample collection unit 300, and it is preferable that the number of sample inlets and outlets 360R1, 360R2 are arranged in a row in the longitudinal direction of the sample collection unit 300.

[0049] In other words, as shown in Figure 3, the sample collection unit 300 has a cylindrical shape with an internal containment space 310 capable of accommodating a sample. When a number of sample inlets and outlets 360R1 and 360R2 are formed in a manner that crosses from the outer surface of the sample collection unit 300 toward the inner central axis LX, a configuration is formed on the outer surface of the sample collection unit 300, as shown in Figure 4 or Figure 5, in which a number of sample inlets and outlets 360R1 and 360R2 communicating with the containment space 310 are formed.

[0050] Here, the sample inlets and outlets 360R1 and 360R2 are not in the form of holes that penetrate linearly perpendicular to the longitudinal central axis LX of the sample collection section 300. Preferably, the sample inlets and outlets 360R1 and 360R2 are formed in the form of grooves 360E that start from the sample inlets and outlets 360R1 and 360R2 and are formed across to the central axis LX side of the sample collection section, as shown in Figures 4 to 6, that is, grooves 360E in which the ends of the sample inlet and outlet channels are closed.

[0051] Thus, the numerous sample inlets and outlets 360R1 and 360R2 are not in the form of straight, penetrating holes, but rather have closed ends, forming groove-like structures. Therefore, samples flowing into the sample inlets and outlets 360R1 and 360R2 can enter the containment space 310 and be contained within the containment space 310 without passing through to the other side.

[0052] Preferably, a number of sample inlets and outlets 360R1, 360R2 are formed on the outer surface of the sample collection section 300, and the number of sample inlets and outlets 360R1, 360R2 are arranged in a row in the longitudinal direction of the sample collection section 300, as shown in the drawing.

[0053] To describe the configuration in which the numerous sample inlets and outlets 360R1 and 360R2 are arranged in a row along the longitudinal direction of the sample collection section 300, a number of sample inlets and outlets 360R1A, 360R1B, and 360R1C are formed in a row along the longitudinal central axis LX from the rear side of the sample collection section 300, which is connected to the front end of the support section 200, toward the front side of the sample collection section 300.

[0054] Here, the numerous sample entry / exit ports 360R1A, 360R1B, and 360R1C are arranged in a single row, that is, in the first row.

[0055] Furthermore, the numerous other sample entry / exit ports 360R2A, 360R2B, and 360R2C are formed in another row. Here, the numerous sample entry / exit ports 360R2A, 360R2B, and 360R2C are arranged in another row, i.e., a second row.

[0056] As shown in Figure 2 or Figure 4, it is also preferable that the direction in which the numerous sample inlets / outlets 360R1 belonging to the first row open is opposite to the direction in which the numerous sample inlets / outlets 360R2 belonging to the second row open.

[0057] Furthermore, it is preferable that the numerous sample inlets and outlets 360R1 and 360R2 are arranged in a first and second row, with the first and second rows forming on either side of the longitudinal central axis LX of the sample collection section 300.

[0058] Here, it is preferable that the sample inlet / outlet 360R1 belonging to the first row and the sample inlet / outlet 360R2 belonging to the second row are arranged alternately in the longitudinal direction of the sample collection section 300, as shown in the drawing.

[0059] The first row of sample inlets 360R1 and the second row of sample inlets 360R2 are arranged alternately in the longitudinal direction of the sample collection section 300. As described above, the numerous sample inlets 360R1 and 360R2 are not formed as holes that penetrate perpendicularly across the longitudinal central axis LX of the sample collection section 300, but rather as grooves 360E-like structures where the opposite sides of the sample inlets 360R1 and 360R2 are closed.

[0060] Therefore, during the sample collection process, it is possible to prevent samples flowing into the sample inlet / outlet 360R1 and 360R2 and entering the containment space 310 from passing across the central axis LX and exiting, while maintaining the state in which the samples are contained within the containment space 310.

[0061] Furthermore, it is preferable that the sample inlet / outlet channel 360F becomes narrower or wider as the sample enters from the sample inlet / outlet 360R1 and 360R2 in a direction that crosses the longitudinal central axis LX of the sample collection section 300. In other words, it is preferable that the sample inlet / outlet channel 360F becomes narrower or wider as the sample enters inward from the sample inlet / outlet 360R1 and 360R2.

[0062] For example, as shown in Figures 4 and 6, the height 360h of the sample inlet / outlet channel 360F decreases as you move from the sample inlet / outlet 360R1A towards the central axis LX, making the sample inlet / outlet channel 360F narrower.

[0063] Furthermore, by forming the sample inlet / outlet channel 360F in such a way that its width 360W decreases as it moves from the sample inlet / outlet 360R1A towards the central axis LX, it is also possible to create a configuration in which the sample inlet / outlet channel 360F becomes narrower.

[0064] Thus, having a configuration in which the sample inlet / outlet channel 360F becomes narrower as the sample enters inward from the sample inlet / outlet 360R1 and 360R2 is preferable because it allows for the collection of samples that flow in through the sample inlet / outlet 360R1 and 360R2 and enter the containment space 310 inside the sample collection unit 300.

[0065] Since the samples that flow into the sample inlet / outlet channel 360F or that accumulate in the containment space 310 have a certain cohesive force, the detachment of the sample collection unit 300 to the outside is suppressed during the sample collection process.

[0066] Furthermore, when the sample collection unit 300 is immersed in the fixative solution, the sample held or contained in the sample collection unit 300 can be easily dispersed into the fixative solution, thereby increasing the amount of sample in the fixative solution.

[0067] In other words, when the sample collection unit 300 is immersed in the fixative solution, the fixative solution flows into the containment space 310. Consequently, the containment space 310 becomes filled with the contained sample and fixative solution, and some of the sample disperses into the fixative solution. In this state, shaking the support unit 200 to shake the sample collection unit 300 increases the amount of sample dispersed into the fixative solution and helps the dispersed sample to flow out of the containment space 310 to the outside of the sample collection unit 300.

[0068] In particular, if the sample inlet / outlet channel 360F becomes narrower as the sample enters inward from the sample inlet / outlet 360R1 and 360R2, the inlet / outlet channel 360F will conversely expand in the direction from inside the containment space 310 toward the sample inlet / outlet 360R1 and 360R2. Therefore, it is possible to ensure that a certain amount or more of the sample contained inside the containment space 310 disperses into the fixative solution and exits to the outside through the sample inlet / outlet 360R1 and 360R2.

[0069] Therefore, the amount of sample collected can be increased, and more than a certain amount of the sample contained in the containment space 310 can be dispersed in the fixative solution and exit the sample collection unit 300.

[0070] Furthermore, a configuration in which the containment space 310 of the sample collection unit 300 is divided into two or more separate spaces is also preferable.

[0071] Figure 7 is a schematic side cross-sectional view showing a modified sample collection section in a sample collection stick according to an embodiment of the present invention. As shown in Figure 7, it is also preferable to have one or more partition walls 320 inside the sample collection section 300 that spatially divide the containment space 310.

[0072] Figure 7 illustrates an example with a single partition wall 320. This single partition wall 320 divides and separates the accommodation space 310 into two accommodation spaces 310A and 310B.

[0073] The presence of one or more partitions 320 within the containment space 310 helps to agglomerate surrounding samples when viscous samples adhere to the partitions 320. Therefore, it is possible to ensure the collection of a certain amount or more of samples using containment spaces 310A and 310B separated by one or more partitions 320.

[0074] Thus, the partition wall 320 and containment spaces 310A and 310B provided in the sample collection section 300 are preferable because they help to allow a certain amount or more of the sample to remain in the sample collection section 300 while agglutinating.

[0075] Thus, by providing one or more partitions 320, or by dividing the partitions 320 into multiple containment spaces, the amount of sample that detaches from the containment space 310 within the sample collection section 300 during the process of collecting a sample in the body is greatly reduced, thereby increasing the amount of sample collected. Furthermore, the amount of the collected sample that dissolves or disperses in the reagent or solution from the sample collection section 300 of the sample collection stick 10 can be increased.

[0076] As described above, the sample collection stick according to the embodiment of the present invention can contain the sample to be collected within the containment space of the sample collection section, and prevents the sample that has flowed into the containment space from escaping to the outside, so that the amount of sample collected can be relatively increased compared to conventional sample collection swabs.

[0077] Furthermore, unlike conventional methods, there is no fiber layer, so when the sample collection section is immersed in the fixative solution, the sample held or contained in the sample collection section can easily disperse into the fixative solution, thus increasing the amount of sample in the fixative solution.

[0078] Thus, the sample collection stick according to the present invention has the advantage of reducing the manufacturing cost of sample collection sticks because it does not require the flocking process required in the manufacturing process of existing sample collection swabs, and because the sample collection stick does not have a fiber layer, there is no risk of the fiber layer coming off and remaining in the body of the person being tested, as is the case with existing sample collection swabs.

[0079] Furthermore, the sample collection stick according to the present invention has the advantage of being able to increase the amount of sample collected from the person being tested compared to conventional swabs, and increasing the amount of the collected sample that dissolves or disperses from the sample collection stick into the reagent or solution, thereby improving the accuracy of the test by increasing the amount of sample collected.

[0080] Furthermore, the sample collection stick according to the present invention can reduce the time required for sample collection and alleviate inconvenience for the person being tested during sample collection. In addition, since the sample collection portion, which is inserted into the oral or nasal cavity of the person being tested, is made of a flexible and elastic polymer material or elastomer material, it also has the advantage of reducing inconvenience for the user.

[0081] As described above, the specific details of the present invention have been disclosed based on embodiments with reference to the attached drawings. However, since the embodiments described above are merely examples of preferred embodiments of the present invention, it should not be understood that the present invention is limited only to the embodiments described above. The scope of the rights of the present invention must be understood by the claims and equivalent concepts described later. [Explanation of Symbols]
