Swab for sample collection {A SWAB FOR COLLECTING SAMPLE}

The present invention relates to a swab for sample collection, and more particularly, a curve is formed in the sample collection part to increase the amount of sample filling, and a notch is formed to break it into various lengths depending on the length of the transport container. On the other hand, it relates to a swab for sample collection, which is configured to be such that the length of the handle is variable by providing a variable handle so that the length can be changed according to a child or an adult.

In general, fluff swabs (swab) are used to collect mucus or tissue from a person's nose, mouth, ears, etc., and is also used to collect samples for diagnosing infection with pathogens or viruses in hospitals.

Recently, the swine flu (coronavirus: COVID-19), which has a high rate of transmission and a very high fatality rate due to airborne transmission, is widely prevalent around the world. As the death of

is being done in

In order to confirm this type of H1N1 influenza test, a sample must first be collected from the person being tested. After inserting a swab for sample collection inside the nasal cavity or oral cavity where the actual infection takes place, the mucous membrane of the nasal cavity or oral cavity secretions are collected from

In the case of collecting a sample from the nasal cavity, insert a sample collection swab so that it touches the inner wall of the nasal cavity, the part from which secretions are produced the most, and rotate the sample collection swab while rotating the sample collection swab in a sufficient amount so that the secretions are visible. to collect

In addition, if the sample is to be collected from the oral cavity, the subject must open their mouth wide and then use a tongue depressor to press the tongue while touching the surface of the tonsils on the inner wall of the throat or the inside of the pharynx, which is the part where secretions are produced the most. Insert a cotton swab for sample collection and rotate the sample collection swab to collect sufficient samples.

However, in the conventional swabs, the cilia of the sample collection unit for collecting the sample are arranged in the form of water droplets or cylinders, that is, the cilia of the sample collection unit are wound like the cotton swabs we use commonly, so it is difficult to collect a large amount of sample. There was a difficult problem.

In addition, if the sample is not collected, the swabs must be inserted deep into the oral cavity or nasal cavity, but the length of the swabs is short, so there is a problem that the sample has to be collected several times.

[First embodiment]

1 is a block diagram of a swab for sample collection according to a first embodiment of the present invention.

As shown in Figure 1, the present invention forms a curve in the sample collection section to increase the filling amount of the sample, and also forms a number of notches so that it can be broken into various lengths depending on the length of the transport container. It relates to a swab 100 for collecting a sample.

The swab 100 for sample collection according to the first embodiment of the present invention is largely composed of four parts, a handle portion 10, an extension portion 20, a head portion 30, and a sample collection portion 40. is composed of

Here, the handle portion 10, the extension portion 20, and the head portion 30 are integrally configured to enable production with a single mold.

And in the handle portion 10, a plurality of notches 11 are formed at regular intervals so that the sample collection unit 40 filled with the sample can be broken to various lengths depending on the length of the transport container (not shown). can In this case, the first notch 11 may be formed at an interval of 7 cm to 9 cm from the end of the head unit 30 , and each notch 11 may be formed at an interval of 5 mm to 10 mm.

In addition, the extension portion 20 is formed to have a relatively thinner diameter than the diameter of the handle portion 10 so as to secure flexibility according to the shape of the nasal cavity or oral cavity of the human body.

And the head portion 30 is formed on one side of the extension portion 20, the tip is further formed with a guide sphere 33 for smooth entry into the nasal cavity or oral cavity.

The guide sphere 33 serves to guide the sample collection unit 40 deep into the oral cavity while preventing damage to the oral or nasal mucosa through the curved surface.

In addition, the sample collection unit 40 is adhered through the pressure-sensitive adhesive layer 32 applied to the outer peripheral surface of the head unit 30 to fill the sample in the oral cavity or nasal cavity. Can be composed of a plurality of cilia 41 have.

The sample collection unit 40 is formed like fine hairs (fluffs) formed on human skin so that a sample can be collected between each cilia.

Here, the sample collection unit 40 can be manufactured by binding the cilia attached to the cilia using static electricity in a state in which the cilia 41 particles of a certain length are scattered inside the housing by the restraint by the pressure-sensitive adhesive layer.

In this manufacturing process, it is necessary to use a suitable pressure-sensitive adhesive layer because the cilia 41 particles must be stably adhered to the outer circumferential surface of the head unit 30 . In addition, since it is inserted into the oral cavity or nasal cavity, ingredients that are harmless to the human body must be used. In general, an acrylic pressure-sensitive adhesive layer may be used, but when a commercially available acrylic pressure-sensitive adhesive layer is used, the cilia 41 particles scattered in the state before the pressure-sensitive adhesive layer is cured may not be uniformly adhered. Since it is not stably adhered to the outer peripheral surface of the head part 30, it is necessary to optimize the acrylic adhesive layer in consideration of this.

In one embodiment, the acrylic pressure-sensitive adhesive layer is prepared as follows.

35 parts by weight of ethyl acrylate monomer (EAM), 35 parts by weight of butyl acrylate monomer (BAM), 30 parts by weight of 2-ethylhexyl acrylate monomer (2-EHA), 2 parts by weight of acrylic acid, and 0.5 parts by weight of AIBN (Azobis isobutyronitrile) A resin composition was prepared by reacting parts by weight, and 30 parts by weight of a mixture of dimethyl silicone oil and PEO-b-PDMS (poly(ethylene oxide)-bpoly(dimethylsiloxane)) in a weight ratio of 3:1 was added, followed by isocyanate An improved acrylic pressure-sensitive adhesive layer was prepared by adding 5 parts by weight of a curing agent.

Mixing the silicone oil component and the siloxane component is known to form an oil-water emulsion, and through this, the pressure-sensitive adhesive layer layer is formed around the cilia when the cilia 41 particles are adsorbed while the viscosity of the pressure-sensitive adhesive layer is low. It has been shown to cause fast and stable adhesion.

A swab prepared by applying a conventional acrylic adhesive layer to the head part 30 and scattering cilia 41 particles and the improved acrylic adhesive layer are applied to the head part 30, and the cilia 41 particles are scattered. In order to compare the prepared swabs, the amount of cilia lost was measured after moving 5 cm in a state where the cilia of the swabs were in contact with the surface of 800 sheets of sandpaper. As a result, when prepared using a conventional acrylic pressure-sensitive adhesive layer, the amount of cilia lost reached 20 to 30%, but in the case of a swab prepared using the improved acrylic pressure-sensitive adhesive layer, the amount of cilia lost was only 5 to 10%, making it much more stable It was found that the adhesive state was maintained. This degree of adhesion is such that when the head unit 30 is inserted into the oral cavity or nasal cavity, the cilia hardly occur.

In addition, each cilia 41 has a thickness of 1.3 detex (DTeX) to 1.6 detex, and if it is less than 1.3 detex, rigidity of the cilia decreases and manufacturing cost is high. It is undesirable because it feels foreign to the oral or nasal passages. In addition, the cilia 41 of the thickness can be easily attached to the acrylic pressure-sensitive adhesive layer and can stably maintain an adhesive state, thereby solving the problem of detachment from the head unit 30 .

Meanwhile, the head part 30 may further have at least two annular protrusions 31 having a trapezoidal or wavy shape to form a curve in the sample collecting part 40 .

The annular protrusion 31 forms a curve in the sample collection unit 40 so that the sample can be filled not only between the cilia 41 and the cilia 41, but also between the peak and the valley of the curve, so that more samples are collected. function to be

[Second embodiment]

FIG. 2 is a configuration diagram showing a variable handle of a swabs for sample collection according to a second embodiment of the present invention, and FIG. 3 is a configuration diagram showing the rail unit extracted from FIG. 2 .

As shown in Figures 2 and 3, the second embodiment includes the first embodiment, except that the handle portion 10 is provided with a variable handle portion 50 having a variable length, depending on the child or person. It relates to a swab 100 for collecting a sample that can vary in length.

The swab 100 for sample collection of this second embodiment has a structure in which the length of the sample collection unit 40 can be further increased by extending the length of the sample collection unit 40 deep into the oral cavity or nasal cavity.

Here, the handle portion 10 is further formed with a rail portion 12 extending to the other side having a relatively small diameter.

At this time, the rail part 12 has a variable handle part 50 having the same diameter as the handle part 10 , and is configured to selectively extend the length of the handle part 10 by force fitting.

And since the other end of the rail part 12 is formed with a cone-shaped insertion cone 12a, when the variable handle part 50 is separated from the rail part 12, it can be configured so that it can be quickly coupled.

In addition, a scale 121 may be formed on the surface of the rail part 12 to identify the extended length of the variable handle part 50 .

In addition, in another embodiment, the rail part 12 partially applies the color part 122 in addition to the scale on the other side so that when the color part is identified by the user, the variable handle part 50 may be separated from the rail part 12. It can be configured so that it can be recognized that there is.

[Third embodiment]

4 is a block diagram of a swab for sample collection according to a third embodiment of the present invention.

As shown in FIG. 4 , the third embodiment includes the first embodiment and/or the second embodiment, except that the sample collection swab 100 is an oral or nasal specimen (mucus, tissue, secretion). It can be configured by adding a suction function so that it can be collected by suction.

To this end, the handle portion 10 may further include a suction hole (H) that passes through the extension portion 20 to the tip of the guide sphere 33 .

At this time, the suction hole (H) is used as an inlet for sucking the sample, and has a function of securing the flexibility of the handle part 10 and the extension part 20, and an additional function of lowering the consumption of raw materials. have.

In addition, a suction tube 60 in the form of a “disc” or “sphere” is further coupled to the other end of the handle portion 10 , and the suction tube 60 may be made of synthetic resin or natural rubber having excellent elasticity.

The third embodiment can be used when the virus or bacteria contained in the user's sample is not collected.

In particular, in the secondary examination because no virus or bacteria in the sample is detected, the sample collection unit 40 is introduced into the oral cavity or nasal cavity in a compressed state of the suction tube 60, and then is sucked by the suction tube 60 False diagnosis can be prevented by introducing a sample together with air into the extension part 20 to collect a larger amount of sample.

The embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and examples.
