Abstract
Description
[0001] Priority application
[0002] This application claims priority to Chinese invention patent application No. CN202311458765.5, filed on November 3, 2023, entitled "A Throat Swab Collector", which is incorporated herein by reference in its entirety. Technical Field
[0003] This invention relates to the field of medical assistive device technology, and in particular to a data acquisition device. Background Technology
[0004] Respiratory infections are usually diagnosed by collecting oropharyngeal or nasopharyngeal swabs to determine the type of virus, which involves pathogen detection. Oropharyngeal swabs are more widely used because they are convenient to collect and have better compliance with sampling.
[0005] Traditional samplers all use a rod-shaped design. For example, CN202122000255.6 discloses an easy-to-use pharyngeal swab sampling stick; WO2021237293A1 discloses a swab; US20210315552A1 discloses a biological sample collection instrument; and for another example, US20220387228A1 also discloses a 3D-printed nasal pharyngeal and oral swabs.
[0006] This rod-shaped sampling stick requires the sampling tip (i.e., the sampling cotton) to locate a sampling point on the mouth or nose of the subject. However, this sampling method requires a high level of expertise from the sampling personnel, and when used on subjects with relatively poor cooperation, such as children, the operator will find it difficult to perform the sampling operation smoothly.
[0007] To improve the cooperation of those being sampled, CN202222440836.6 discloses a pediatric pharyngeal swab collection aid. The main working mode of this aid is as follows: first, an arc-shaped plate and a limiting plate are used to firmly press against the child's mouth, ensuring the mouth remains stably open and closed. Then, the pharyngeal swab body is moved left and right to locate the sampling point and complete the collection. In addition, CN202120523713.1 also discloses a pediatric pharyngeal swab collection mouth opening device. Both of these aids are essentially oral dilators. However, this method of expanding the oral cavity for sampling is more complex in terms of operation and still requires finding a sampling point for sample collection. Therefore, it does not significantly improve the sampling experience for those being sampled.
[0008] Therefore, there is an urgent need for a throat swab collection device that can be operated by adults by reading the instructions and is also more child-friendly for sampling. Summary of the Invention
[0009] The purpose of this invention is to provide a collector that partially solves or alleviates the above-mentioned shortcomings in the prior art, effectively improves the low elution efficiency of the collector, and optimizes the sampling experience of the collected objects.
[0010] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: a data collector, comprising:
[0011] First shot;
[0012] A deformable portion for sampling is disposed at a first end of the first rod, and the deformable portion includes at least two deformable members for contact sampling with the area to be sampled; and the deformable members are rotatable relative to the first rod so that the deformation angle gradually increases or decreases, wherein the deformation angle is the angle formed by the intersection of the first axis of the first rod and the second axis of the deformable member;
[0013] The second rod is connected to the first rod in a relatively movable manner, and a pushing part is provided at the first end of the second rod; wherein, when the second rod moves along a preset unfolding direction, the pushing part pushes the deformable part to deform and rotate, at which time the deformation angle gradually increases, and the deformable part gradually changes from the initial state to an arc-shaped bending state in its length direction;
[0014] During deformation and rotation, adjacent deformable parts form additional unfolding space, and the outer surface of the deformable parts gradually comes into contact with the area to be sampled. At this time, the new deformable part shape formed by the sequentially arranged deformable parts and the additional unfolding space increases the effective contact area between the deformable parts and the area to be sampled.
[0015] In some embodiments, the material of the deformable part has a hardness of 30A-90A.
[0016] In some embodiments, the deformable member is provided with a first deformation segment, a second deformation segment, and a third deformation segment sequentially from the first end to the second end; wherein the hardness design ranges of the first deformation segment, the second deformation segment, and the third deformation segment are 30A-50A, 40A-60A, and 50A-90A, respectively; and deformation openings are symmetrically provided at the connection sections of at least two adjacent deformation segments, the deformation openings being used to guide the deformable member to produce arc-shaped bending deformation at the hardness difference.
[0017] In some embodiments, a plurality of first protrusions are spaced apart along a first direction on the outer side of the deformable member, and a plurality of second protrusions are spaced apart along a direction intersecting the first direction. Sampling holes are also provided in the adjacent areas of the first and second protrusions, so that the deformable member can generate capillary action when in contact with a liquid sample to enhance the suction force on the liquid sample.
[0018] In some embodiments, there is a height difference between adjacent first protrusions or second protrusions.
[0019] In some embodiments, the width of the pushing portion gradually decreases along the direction from its first end to its second end.
[0020] In some embodiments, the first rod is provided with at least one limiting hole, and the second rod is provided with at least one elastic limiting member corresponding to it. The elastic limiting member is capable of reciprocating along the radial direction of the second rod under the action of an external force, and when the elastic limiting member extends into the limiting hole, the deformation angle is limited to a corresponding preset angle range.
[0021] In some embodiments, the elastic limiting member includes: a limiting protrusion, with a first inclined surface and a second inclined surface respectively provided on both sides of the limiting protrusion; the first inclined surface and the second inclined surface are connected by an arc-shaped surface, and the width of both sides of the limiting protrusion gradually increases from its first end to its second end, and the second end of the limiting protrusion is connected to the elastic member;
[0022] When the elastic limiting member cooperates with one of the limiting holes to perform gradient limiting, the first end of the limiting protrusion passes through the limiting hole and protrudes outward to play a gradient limiting role.
[0023] When the second rod is subjected to an external force along the first direction for gradient adjustment, the edge of the limiting hole will press against the corresponding inclined surface. Consequently, the spring will contract under the pressure of the inclined surface and drive the limiting protrusion into the inner space of the first rod. When the limiting member moves to another limiting hole under the action of the external force, the spring will drive the limiting protrusion through the limiting hole under the action of automatic reset, thereby realizing gradient adjustment.
[0024] In some embodiments, a second anti-slip portion is provided on the second rod near its second end.
[0025] In some embodiments, the second end of the deformable portion extends to form a mounting sleeve, the deformable portion is sleeved on the first rod through the mounting sleeve, and the first rod is also provided with a limiting portion to limit the tendency of the mounting sleeve to move toward the second end of the first rod.
[0026] Alternatively, in some embodiments, the deformable part is integrally connected to the first rod, and the connection between the deformable part and the first rod is designed with a breakable structure.
[0027] Beneficial technical effects:
[0028] In the data collector, multiple deformable components can unfold in an approximately trumpet shape under the pushing action of the pusher, with adjacent deformable components creating additional unfolding space as they gradually unfold. The sequentially spaced deformable components and the unfolding space created by their unfolding together form a trumpet-like shape. Furthermore, this trumpet-like design increases the effective sampling area of the deformable components without increasing the overall sampling area.
[0029] Furthermore, this invention provides a multi-segment hardness difference design, which, in conjunction with the sampling morphology design of the protrusion site, creates a flexible deformation sampling scheme. Thus, the multi-segment hardness difference design not only facilitates effective contact sampling between the protrusion site and the oral cavity, but its flexible deformation capability also reduces potential improper contact at the protrusion site (such as excessive friction leading to reduced user comfort).

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] In this specification, certain embodiments may be disclosed in a range-bound format.

The above rules apply regardless of the breadth of the range.
[0052] In this article, "arc bending state" is also referred to as arc state, which means that at least a length of the axis of the deformable part 111 (e.g., at least one deformable segment, or a portion of the length of the deformable segment) deviates or bends from the straight line or horizontal (or the initial state), so that it exhibits a shape that is the same as or approximately the same as a circular arc or elliptical arc.
[0053] Example 1
[0054] like Figures 1-8 As shown, this embodiment provides a data collector, including:
[0055] First shot: 10;
[0056] A deformable portion 11 for sampling is disposed at a first end of the first rod, and the deformable portion 11 includes at least two deformable members 111, which are used to make contact with the area to be sampled; and the deformable members are rotatable relative to the first rod, thereby causing the deformation angle to gradually increase or decrease, wherein the deformation angle is the angle formed by the intersection of the first axis L1 of the first rod and the second axis of the deformable member; and the angle gradually increases as the deformable member gradually unfolds;
[0057] When using a throat swab collector for sampling, the endpoints of multiple deformable parts (i.e., sampling sites) can come into contact with the oral cavity wall of the subject being sampled, thereby collecting the test sample.
[0058] The second rod (i.e., the angle adjustment rod) 12 is connected to the first rod 10 in a relatively movable manner. A pushing part 121 is provided at the first end of the second rod. The outer edge of the pushing part contacts the inner surface of the deformable member, thereby abutting and controlling the unfolding of the deformable member during the pushing process. Specifically, when the second rod moves along a preset unfolding direction (i.e., the direction from the first end of the first rod to the second end), the pushing part 121 pushes the deformable member to deform and rotate. At this time, the deformation angle gradually increases, thereby expanding the effective sampling area of the deformable part. Furthermore, as the deformation angle gradually increases, the deformable member 111 can gradually transform from an initial state (e.g., a nearly vertical straight state) to an arc-shaped bending state along its length.
[0059] In some embodiments, multiple deformable members 111 are connected near their second ends, and the first ends of the deformable members 111 can gradually expand outwards. During this expansion, the deformation angle of the deformable portion and the shape of the deformable member itself will undergo synchronous deformation. This dual synchronous deformation of angle and shape (e.g., becoming curved) makes the external shape of the deformable portion resemble or be similar to that of a horn. Furthermore, when the external shape of the deformable portion is the same as or similar to the surface shape of the area to be sampled, the outer surface of the deformable member can contact the area to be measured, thereby increasing the effective sampling area of the deformable member and efficiently completing sampling using the deformable member.
[0060] Specifically, in this embodiment, multiple deformable components can unfold in an approximately trumpet shape under the pushing action of the pushing unit. Adjacent deformable components 111 gradually unfold, forming additional unfolding spaces 113 (for example, in some embodiments, the unfolding spaces 113 are triangular or approximately triangular in design). The sequentially spaced deformable components 111 and the unfolding spaces 113 formed by the unfolding of the deformable components together form a trumpet-like shape. Furthermore, this trumpet-like shape design can increase the effective sampling area of the deformable components without increasing the design sampling area.
[0061] In other words, the dual synchronous deformation mode designed in this embodiment can significantly increase the sample collection volume of the deformation part without increasing the material consumption of the deformation part.
[0062] The design sampling area refers to the area that one or more deformable parts can collect samples from when they are in full contact with the area to be sampled (for example, the area of the outer surface of the deformable part is the design sampling area). The effective sampling area refers to the area that one or more deformable parts can effectively contact the area to be sampled and collect samples during the actual sampling process through dual synchronous deformation.
[0063] The collector in this embodiment is preferably suitable for sampling areas that are cone-shaped, arc-shaped, or trumpet-shaped (typically the oral cavity).
[0064] In some embodiments, a plurality of first protrusions (also referred to as sampling protrusions or sampling sites) are provided at intervals along a first direction on the outer side of the deformable member 111, and a plurality of second protrusions are also provided at intervals along a second direction (e.g., the direction in which the first axis L1 is located) that intersects the first direction. Furthermore, sampling holes are provided in the adjacent areas of the first protrusions and the second protrusions, so that the deformable member can generate capillary action when in contact with a liquid sample to enhance the suction force on the liquid sample.
[0065] For example, in some embodiments, the orientation (or arrangement direction) of the first protrusion is perpendicular or approximately perpendicular to the orientation of the second protrusion.
[0066] In this article, "perpendicular" refers to a state in which the angle between one line (or surface) and another line (or surface) is perpendicular or approximately perpendicular. For example, in this article, the setting directions of the first and second protrusions are perpendicular to each other, which means that the angle between their setting directions is approximately 90° (or around 90°, such as 80°, 85°, 89°, etc.).
[0067] In some embodiments, the sampling hole penetrates both the outer and inner sides of the deformable part, meaning the deformable part has a hollow structure design.
[0068] In a preferred embodiment, the first protrusion is a protruding sidewall arranged along the width direction (or circumferential direction) of the deformable part; the second protrusion is a protruding sidewall arranged along the length direction of the deformable part; at this time, the first protrusion and the second protrusion intersect to form a "well"-like design.
[0069] In some embodiments, there is a height difference between adjacent first protrusions or second protrusions.
[0070] Alternatively, in other embodiments, the multiple first protrusions or second protrusions may have different protrusion heights, so that the cross-sectional shape of the outer side of the deformable part (i.e. the side that can contact the oral cavity wall during sampling) is designed with irregular height differences.
[0071] To improve sampling efficiency, the first and second protrusions are arranged closely together.
[0072] As another preferred embodiment, the first protrusion may be a plurality of first protrusion sites arranged along the width direction. Correspondingly, the second protrusion may be a plurality of second protrusion sites arranged along the direction intersecting with it, and a sampling hole is provided between adjacent protrusion sites.
[0073] Among them, the protruding point can be a sampling needle that protrudes outward along the outer side of the deformed part, and the tip of the sampling needle has a rounded and blunt structure.
[0074] In other words, the deformable component in this embodiment can also be designed with multiple teeth. Furthermore, to improve sampling efficiency, the multiple first protrusion sites and second protrusion sites can also have different protrusion heights, forming a gradient difference design.
[0075] The above-described sidewall protrusion design and protrusion point design are preferred embodiments of this application. It is understood that the protrusion shape, height, density, etc. of this application can also be flexibly adjusted according to actual materials and sampling requirements, and this application does not impose any limitations.
[0076] In some embodiments, the length Y of the deformable portion is approximately 1-2 cm.
[0077] In some embodiments, in order to enable the deformable part to unfold more stably in an arc-shaped bending manner during deformation, and to reduce the damage that the arc-shaped unfolding process may cause to the sampling area (such as the oral cavity), the hardness of the material used to prepare the deformable part is approximately 30A-90A.
[0078] It is understood that this embodiment uses Shore hardness to describe the physical properties of the material. Shore hardness refers to the reading obtained using a Shore hardness tester, and its unit is "degrees". There are two methods of description: A and D, representing different hardness ranges. The range of the Shore A hardness tester is 0-100HA, and the range of the Shore D hardness tester is 0-100HD. The reading is the standard.
[0079] like Figure 9 As shown, the deformable component in this embodiment adopts a multi-segment hardness difference design (i.e., a multi-segment toughness design). Preferably, the deformable component includes a first deformable segment 1111, a second deformable segment 1112, and a third deformable segment 1113 connected sequentially from the first end to the second end of the deformable component, and the hardness of the first deformable segment is less than or equal to that of the third deformable segment. Furthermore, each deformable segment is uniformly provided with protruding sites and sampling holes (not shown in the figure).
[0080] Preferably, in some embodiments, the hardness design ranges of the first deformation segment, the second deformation segment, and the third deformation segment are 30A-50A, 40A-60A, and 50A-90A, respectively.
[0081] It is worth noting that hardness is usually a physical measure of a material's degree of deformation under pressure or its resistance to puncture. In this article, hardness can refer to the physical properties inherent in the material itself, or it can refer to the degree of deformation under pressure or its resistance to puncture exhibited by the material after processing (e.g., thickness design, length design, shape design).
[0082] Furthermore, in some embodiments, the dimensions of the first, second, and third deformable segments are designed as follows: the length range of each deformable segment is 2-8 mm; 5-15 mm; 2-8 mm; and the thickness range of each deformable segment is 2-6 mm; 3-8 mm; 3-8 mm. As an exemplary embodiment, the lengths of the first, second, and third deformable segments are approximately 5 mm, 10 mm, and 5 mm, respectively, and correspondingly, the thicknesses of the first, second, and third deformable segments are 4 mm, 5 mm, and 5 mm, respectively.
[0083] Preferably, in this embodiment, the design of multi-segment hardness difference can be achieved more simply and flexibly by differentiating the hardness of the length and thickness, and this hardness difference design based on length and thickness will not increase the processing difficulty of the deformed part.
[0084] Furthermore, in some embodiments, at least one deformation opening (e.g., a notch located at the junction of the deformation segments) may be provided between at least two adjacent deformation segments, the deformation opening being able to guide the deformation member to produce arc-shaped bending deformation at the corresponding position.
[0085] Specifically, a deformation opening is symmetrically provided on both sides of the connecting section between two adjacent deformation segments. The symmetrically designed deformation opening can be matched with the hardness difference to synchronously guide the two deformation segments with different hardness to produce an arc-shaped bend.
[0086] It is understood that the three-segment hardness design in this invention is only a preferred multi-segment design. This invention may also sample other multi-segment designs (such as two-segment designs) according to actual conditions, and this invention does not limit this.
[0087] In this embodiment, the multi-height-difference sampling protrusions (also referred to as sampling points) and the hollowed-out deformable part formed by the sampling holes can increase the collection efficiency of exfoliated cells by utilizing the resulting siphon effect when they come into contact with exfoliated cells in the oral cavity. The accompanying multi-segment hardness difference design not only promotes effective contact sampling between multiple protrusions and the oral cavity, but its flexible deformability also reduces potential improper contact at the protrusions (such as excessive friction leading to reduced user comfort).
[0088] The combination of a multi-sampling-point hollowed-out deformable part and an umbrella-shaped sampling mode can improve sampling efficiency and reduce the discomfort caused by the sampling operation to the object being sampled.
[0089] It should be noted that, unlike traditional point-finding sampling, the operation process of the data collector in this embodiment is as follows:
[0090] The operator inserts the deformable part of the collector into the patient's mouth. At this time, the end of the deformable part does not necessarily need to directly contact the inner wall of the patient's mouth (while finding sampling points requires the sampling end of the swab to repeatedly contact and rub against the inner wall of the mouth). Subsequently, the operator pushes the second rod, which in turn drives the pushing part to open the deformable part (i.e., the deformable part unfolds in an umbrella shape). During the process of the deformable part rotating and unfolding, its multiple sampling points can simultaneously contact and rub against the inner wall of the mouth, and the multi-height difference design can efficiently collect shed cell samples.
[0091] The significant improvement in sampling efficiency also reduces the need for operators to manually rotate the sampler during the process, so the sampling work will not be affected even if the object does not cooperate (such as biting the sampler).
[0092] Furthermore, compared to multiple sampling points, the umbrella-shaped deformation process, combined with multiple sampling sites, enables the collection of the necessary sample volume within a limited time, thus significantly improving sampling efficiency.
[0093] Furthermore, based on the design of the multi-sampling-site deformable component, the deformable component in this embodiment can be made of plastic material (not limited to nylon short fiber fluff material), which can further improve the elution efficiency of the sample.
[0094] In some embodiments, such as Figure 2 , Figure 3 As shown, a pipe space is provided inside the first rod 10, and the second rod 12 can be installed in the pipe space and can reciprocate along its axial direction.
[0095] In some embodiments, the diameter (or width) of the first end of the pushing part is slightly larger than the width of the deformable part in its initial form (i.e., undeformed). As the pushing part gradually extends into the inside of the deformable part, the deformable part deforms and unfolds under force.
[0096] As a preferred embodiment, such as Figure 6 As shown, the cross-section of the pusher can be designed as a cone or a frustum.
[0097] In some embodiments, the length of the pushing part and the length of the deforming part can also be designed to be equal or approximately equal.
[0098] Traditional sampling methods require manual rotation or insertion / extension of the swab for rubbing and sampling, demanding a certain level of expertise from the operator. However, the push-open umbrella design used in this embodiment largely replaces manual sampling, thus mitigating operational errors caused by improper techniques (such as sampling failure due to uncooperative subjects, or insufficient sample size due to improper sampling location or insufficient sampling time). This improves both operational efficiency and the reliability of the sampling results.
[0099] Furthermore, the arc-shaped structure at the top of the oral cavity, in this embodiment, the open umbrella state (i.e., the movement trajectory of the endpoint of the deformable part is an arc structure) can cooperate with the arc-shaped space at the top of the oral cavity, thereby improving sampling efficiency and optimizing the sampling experience of the sampled object (conversely, it can also enhance the object's compliance).
[0100] In some embodiments, such as Figure 2As shown, the first rod 10 is provided with at least one limiting hole 101, and the second rod 12 is provided with at least one elastic limiting member 122 corresponding to it. The elastic limiting member 122 can reciprocate along the radial direction of the second rod under the action of external force, and when the elastic limiting member 122 extends into the limiting hole 101, the deformation angle is limited to a corresponding preset angle range.
[0101] Preferably, in some embodiments, a marking line is also provided on the first rod corresponding to the limiting hole 101, the marking line being used to indicate the deformation angle size (or, in other words, the preset angle range) corresponding to the limiting hole 101.
[0102] Figure 10 This is a schematic diagram showing the partial engagement relationship between the first and second rods. The elastic limiting member 122 includes: a limiting protrusion 1222 and an elastic member 1221.
[0103] Specifically, the limiting protrusion has a first inclined surface and a second inclined surface on both sides (for example, the limiting protrusion is trapezoidal, conical, frustum-shaped, etc.). The first inclined surface and the second inclined surface are connected by an arc-shaped surface, and the width of the limiting protrusion gradually increases from its first end to its second end; the second end of the limiting protrusion is connected to an elastic element (such as a spring).
[0104] When the elastic limiting member cooperates with one of the limiting holes to perform gradient limiting, the first end of the limiting protrusion passes through the limiting hole and protrudes outward to form a limiting effect.
[0105] Conversely, during gradient adjustment, for example, if the second rod is subjected to an external force (such as tension) along the first direction, the edge of the limiting hole will press against its corresponding inclined surface. Consequently, the spring contracts under the pressure of the inclined surface and drives the limiting protrusion into the inner side of the first rod. Furthermore, when the limiting member moves to another limiting hole under tension, the spring will automatically reset, causing the limiting protrusion to pass through the limiting hole.
[0106] In this embodiment, by using a double-sloping elastic limiting component based on an arc-shaped connection to perform gradient quantitative movement between multiple limiting holes, it can assist users in accurately positioning gradient angles to a certain extent, and is more conducive to guiding users to control the adjustment force under gradient design, avoiding damage to the object due to improper force.
[0107] Preferably, in some embodiments, when the first rod is used for sampling, the deformation angle of its deformable portion ranges from approximately 0 to 45°. For example, the maximum preset angle range is approximately 45°.
[0108] Preferably, in some embodiments, the sampling part can be made of easily deformable plastic, such as plastic with a certain degree of toughness, so that the operator can easily and stably stretch the deformable part during the sampling process, and can flexibly adjust the deformation angle at multiple levels. In this embodiment, using plastic to make the deformable part can also avoid excessive bending deformation to a certain extent, so that the bending deformation is more easily controlled by the flexible design of the deformation angle and hardness difference (that is, it can improve the user's degree of autonomous control over the deformation unfolding process).
[0109] For example, in some embodiments, two or more limiting holes (such as three or four) are spaced apart on the first rod to limit the length of the movement thread of the second rod, thereby limiting the deformation angle to different unfolding angles. When the sampled object is a child, the deformation angle can be limited to a smaller unfolding angle through the limiting holes, while when the sampled object is an adult, the deformation angle can be limited to a larger unfolding angle through the limiting holes. Furthermore, when the operator is not familiar with the oral cavity size of the sampled object, the gradient limiting function can be used for step-by-step unfolding to accurately control the unfolding angle and avoid accidental injury to the object due to improper unfolding.
[0110] In this embodiment, gradient unfolding is preferably achieved through a limiting hole design, so that the user can limit the unfolding speed of the deformable part to a certain extent.
[0111] Alternatively, in other embodiments, the operator may select different unfolding angles depending on the amount of samples required for the project inspection.
[0112] Furthermore, it is worth noting that, in terms of both the specific technical solution and the technical effect achieved, the deformable part in this embodiment differs fundamentally from the umbrella-shaped design used for splash prevention in existing samplers or traditional umbrella-holding technology.
[0113] First, as mentioned earlier, this invention does not aim to achieve a larger design sampling area by expanding the deformable part, but rather to form a dual synchronous deformation scheme by combining a gradient expansion design of the deformation angle with a multi-segment hardness difference design of the deformable part. Therefore, during insertion into the oral cavity, the sampler can slowly expand and efficiently sample samples using a multi-site design under the dual synchronous deformation characteristics.
[0114] This dual synchronous deformation scheme can increase the effective sampling area of the deformable part without increasing the amount of material consumed. At the same time, the gradient unfolding and flexible bending characteristics of the deformable part can also optimize the sampling experience of the object and avoid damage to the oral cavity.
[0115] In some embodiments, such as Figure 1 As shown, a first anti-slip part 102 is provided on the first rod near its first end.
[0116] In some embodiments, such as Figures 1-3 As shown, a second anti-slip part 123 is provided on the second rod near its second end.
[0117] Example 2
[0118] This embodiment also provides a data acquisition device with a separate design for the deformable part and the main body, wherein, for example... Figure 5 As shown, the second end of the deformable portion 11 extends to form a mounting sleeve 112, and the deformable portion is sleeved on the first rod through the mounting sleeve. A limiting portion 103 is also provided on the first rod (e.g., ...). Figure 7 As shown in the figure, it is used to limit the tendency of the mounting sleeve to move toward the second end of the first rod.
[0119] In some embodiments, the limiting portion may be a limiting ring formed by protruding outward along the outer side of the first rod.
[0120] For example, in some embodiments, the limiting part may also be a limiting ring (such as a rubber ring) sleeved on the outside of the first rod.
[0121] In some embodiments, such as Figure 7 As shown, the deformable part 11 is provided with a break line in the direction shown by the first axis L1 (specifically, a break line is provided at the connection between two adjacent deformable parts 111). The wall thickness at the break line can be less than the wall thickness at the main body of the deformable part, or the break line can be a preset gap so that the deformable part can be quickly broken under the action of external force.
[0122] It is understood that the data collector in this embodiment may also include the same or similar component designs as in other embodiments, which will not be described in detail here.
[0123] Example 3
[0124] The difference between this embodiment and embodiment two is that the deformable part in the collector is integrated with the first rod, and the connection between the deformable part and the first rod is designed with a breakable structure.
[0125] For example, in some embodiments, the easily breakable structure is a easily breakable region (e.g., a break line) located at the connection between the deformable part and the first rod, and the thickness of the easily breakable region (e.g., average wall thickness) is less than the main wall thickness of the first rod. When the second rod moves along a preset unfolding direction, the deformable part gradually unfolds. When the pushing part moves to the easily breakable region, it continues to expand the region, and the deformable part breaks off under the operator's force, allowing it to detach and be stored in a test tube for sample elution.
[0126] For example, in some embodiments, the easily broken structure may further include: a break line (preferably, the thickness of the break line is less than the thickness of the main body of the deformable part) provided along the length direction (i.e., the direction of the first axis L1) at the connection between the deformable part and the first rod, so that when the pushing part expands the easily broken structure, the deformable part can quickly crack and detach from the first rod under the action of the pushing part.
[0127] In this embodiment, the sampling design is completed by opening the umbrella. Compared with the rod-shaped design for point sampling, it can achieve two beneficial effects: First, it reduces the professional requirements for sampling and is suitable for a wider range of people, such as children, and is especially suitable for self-sampling by non-professionals, such as home self-testing; Second, it reduces the necessary length of the first rod, reduces the volume, and saves preparation, transportation and storage costs.
[0128] It is understood that the data collector in this embodiment may also include the same or similar component designs as in other embodiments, which will not be described in detail here.
[0129] It is understood that the collector in this embodiment can also be applied to other types of sampling scenarios (e.g., nasal swab collection, etc.).
[0130] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

During deformation and rotation, adjacent deformable parts form a new unfolding space (113). The outer surface of the deformable parts gradually comes into contact with the area to be sampled. At this time, the new deformable part shape formed by the sequentially arranged deformable parts and the new unfolding space increases the effective contact area between the deformable parts and the area to be sampled.

The data collector according to claim 1, characterized in that, The first rod (10) is provided with at least one limiting hole (101), and the second rod (121) is provided with at least one elastic limiting member (122) corresponding to it. The elastic limiting member (122) can reciprocate along the radial direction of the second rod under the action of an external force, and when the elastic limiting member (122) extends into the limiting hole (101), the deformation angle is limited to a corresponding preset angle range.
