Description

Technical Field

[0001] The present invention relates to the technical field of gynecological sampling, and in particular to a gynecological secretion sampling swab and a detection device. Background Art

[0002] In the field of in vitro diagnostics, especially genetic diagnosis, it is necessary to collect isolated human samples for testing. Using a swab is a simple, painless, and non-invasive method for collecting DNA specimens. This method is suitable for collecting DNA samples from people of all ages. Swabs are commonly used to collect microorganisms, exfoliated cells, or secretions for medical examinations.

[0003] In the collection of gynecological secretions, flocked swabs are generally used for collection. A flocked swab is a sampling swab with a flocked head provided on the head thereof, which can be used to sample the cervical os or uterine fornix. However, the existing flocked swab can only select one sampling position. When sampling at multiple positions, multiple samplings are required, resulting in low efficiency.

[0004] In view of this, the existing technology needs to be improved and developed. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a gynecological secretion sampling swab and a detection device, aiming to solve the problem that the flocked swab in the prior art can only sample at one position, resulting in relatively low efficiency.

[0006] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0007] A gynecological secretion sampling swab, comprising:

[0008] Handheld pole;

[0009] A brush head is provided at one end of the handheld rod and is used to collect secretions from the patient's cervix;

[0010] A flocking head is provided on the outer surface of the handheld rod; the flocking head is arranged in an arc shape, and the sampling end of the flocking head is close to the brush head, and is used for collecting secretions from the patient's uterine fornix.

[0011] According to the above technical means, by setting up a dual sampling structure with a brush head and an arc-shaped flocking head, the secretion collection of the cervix and the fornix can be completed simultaneously in a single operation, which has the advantage of obtaining secretion samples from the cervix and the fornix at the same time through a single sampling, thereby improving the sampling efficiency.

[0012] Furthermore, the brush head includes:

[0013] a core shaft, coaxially arranged at one end of the handheld rod;

[0014] A plurality of sampling wires are arranged on the core shaft and are radially arranged.

[0015] According to the above technical means, the core shaft is used to fix multiple sampling wires, and through the radial arrangement of the sampling wires, the contact area with the patient's cervix is increased, effectively improving the adsorption effect on secretions. At the same time, the core shaft can also be used to limit the movement of the sampling wires.

[0016] Furthermore, a spherical block is provided at one end of the core shaft away from the handheld rod, and the sampling wire is located between the spherical block and the handheld rod.

[0017] According to the above technical means, the end spherical block has a blocking effect, and the spherical block also facilitates penetrating deep into the cervix, thereby avoiding damage to the patient's cervix.

[0018] Furthermore, the core shaft is a twisted steel cable, and the plurality of sampling wires are arranged in the steel cable, and the plurality of sampling wires are arranged in a conical shape along the length direction of the core shaft.

[0019] According to the above technical means, the steel cable is formed by folding and rotating a steel wire in half. The sampling wire is located between the folded steel wires, and the sampling wire is arranged radially through the rotation of the steel wire. Then, through trimming, multiple sampling wires can be arranged in a conical shape, which can realize the fixation and radial arrangement of the sampling wire.

[0020] Furthermore, the core shaft is inserted into the interior of the handheld rod.

[0021] This technical approach effectively solves the problem of an unstable connection between the brush head and the handle, preventing relative displacement between the core shaft and the handle during sampling, which could lead to sampling failure. The plug-in structure simplifies the assembly process, ensures the coaxiality of the core shaft and the handle, and enables the multi-layered sampling wire to stably contact the target area, improving the integrity and efficiency of cervical secretion collection.

[0022] Furthermore, the flocking head includes:

[0023] A connecting end is provided on the outer surface of the hand-held rod;

[0024] The sampling end is arranged on the connecting end; the sampling end is arranged in an arc shape to abut against the patient's uterine fornix.

[0025] Based on the above technical means, the present application realizes the one-time complete collection of uterine secretions. The effective contact area between the sampling end and the mucosal tissue is increased so that the sample acquisition amount meets the detection requirements, avoiding repeated sampling operations caused by insufficient contact; at the same time, the adaptability of the arc structure reduces the time consumed by the operator to find the sampling position.

[0026] Furthermore, the apex of the sampling end is lower than the apex of the brush head, and the distance between the side of the sampling end away from the handheld rod and the handheld rod is greater than the maximum distance between the connecting end and the handheld rod.

[0027] Based on the above technical means, the present application realizes the synchronous and interference-free collection of cervical and fornix secretions, ensuring that the flocking head will not affect the cervical sampling operation of the brush head while fully contacting the fornix tissue, effectively avoiding repeated sampling actions and significantly improving the sample acquisition rate of a single sampling.

[0028] Furthermore, the diameter of the sampling end is larger than the diameter of the connecting end, the top of the sampling end is a spherical surface, and the sampling end is wrapped with flocking cloth for collecting secretions from the uterine fornix.

[0029] Based on the above technical means, this application achieves targeted collection of secretions from the fornix, allowing for complete sample acquisition in a single sampling operation while avoiding patient discomfort caused by repeated insertions. The gradually expanding structure allows secretions to be more easily retained within the fiber layer, the spherical end prevents accidental scratching of tissue during sampling, and the directional wrapping of the flocking ensures that the collected sample is concentrated in the effective detection area.

[0030] Furthermore, a notch is provided on the hand-held rod, and the notch is located on a side of the flocking head away from the brush head, and the notch is an annular groove.

[0031] Based on the above technical means, this application realizes standardized control of the sampling swab breaking operation, avoiding the risk of sample contamination caused by fracture surface deviation; the annular groove structure enhances the mechanical stability of the handheld rod when it is broken, ensuring that the brush head and the flocking head are completely retained in the test tube, thereby improving the reliability of sample detection; this design simplifies the operation process of the sampling swab and reduces the technical requirements of the breaking operation for medical staff.

[0032] A gynecological secretion detection device, based on the above-mentioned gynecological secretion sampling swab, comprises:

[0033] Test tubes for holding the brush and flocked heads of sampling swabs;

[0034] A sample pre-processing module, used for processing the sampling swab in the test tube before testing;

[0035] A sample dropping module, used for drawing the sample from the test tube and dropping the sample onto the test strip;

[0036] A test strip detection module is used to perform optical detection on the test strip containing the sample;

[0037] The dyeing tank module is used to add samples to the test strips;

[0038] The visible component detection module is used to perform optical detection on the test strip after sample addition;

[0039] The algorithm processing module is used to analyze the data of the test strip detection module and the tangible component detection module.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] In the present invention, a brush head is provided at one end of the handheld rod, and the brush head is used to collect secretions from the patient's cervix. A flocking head is provided on the outer surface of the handheld rod. The flocking head is arranged in an arc shape, and the sampling end of the flocking head is close to the brush head, so as to collect secretions from the patient's uterine fornix. By providing a dual sampling structure with a brush head and an arc-shaped flocking head, the secretion collection of the cervix and uterine fornix can be completed simultaneously in a single operation, which has the advantage of obtaining secretion samples from the cervix and uterine fornix at the same time through a single sampling, thereby improving the sampling efficiency.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0048] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] In view of the shortcomings of the existing technology, this embodiment provides a gynecological secretion sampling swab and detection device, which can be specifically referred to as follows:

[0050] As attached Figure 1 As shown, a gynecological secretion sampling swab includes a handheld rod 1, a brush head 2 and a flocked head 3; the brush head 2 is located at one end of the handheld rod 1, and the brush head 2 is used to penetrate into the cervix and collect secretions from the patient's cervix; a flocked head 3 is also provided at the end of the handheld rod 1 close to the brush head 2, and the flocked head 3 is located on the outer surface of the handheld rod 1, the flocked head 3 is arranged in an arc shape, and the sampling end 32 of the flocked head 3 is close to the brush head 2, for collecting secretions from the patient's cervical fornix.

[0051] Among them, the handheld rod 1 refers to the rod-shaped body that supports the sampling component, which can be specifically realized by medical plastic injection molding, and its length can be adjusted according to the depth of the patient's uterine cavity. The handheld rod 1 provides an installation reference for the dual sampling component. Among them, the brush head 2 refers to the cervical secretion collection unit, which can be specifically realized by a multi-layer wound nylon bundle, and the axial extension structure adapts to the morphology of the cervical canal. This structure increases the cell adhesion area through the radially extended sampling wire 22. Among them, the flocking head 3 refers to the uterine fornix secretion collection unit, which can be specifically realized by flocking the surface of a medical polymer material molded into an arc-shaped base. The arc curvature of this structure matches the anatomical morphology of the fornix dome, and the transfer efficiency of secretions is improved through curved surface contact.

[0052] Specifically, a handheld rod 1 serves as a basic support structure, and a brush head 2 at its end extends axially into the cervical canal to collect secretions. A flocked head 3, arranged on the outer surface of the handheld rod 1, is curved, with its apex lower than the top of the brush head 2 but the sampling surface facing the fornix. When the swab is inserted into the cervix, the brush head 2 moves axially along the cervical canal to complete sampling of the central area, while the curved surface of the flocked head 3 comes into surface contact with the fornix. The two sampling units simultaneously collect samples from different anatomical sites in a single operation, avoiding repeated insertion and removal operations.

[0053] Compared to existing technologies, traditional single-head swabs require two separate procedures to collect samples from the cervix and fornix, respectively. This solution, however, utilizes dual sampling units arranged in a spatially staggered manner to enable simultaneous sampling of multiple sites in a single procedure. The linear flocked tip 3 used in existing technologies cannot effectively conform to the curved surface of the fornix; this solution utilizes a preformed curved structure to improve anatomical adaptability.

[0054] Through the above technical solution, this application achieves the simultaneous collection of gynecological secretions from multiple locations in a single session, reducing clinical operation steps and patient discomfort time, and reducing the probability of sample cross-contamination. The spatial layout design of the dual sampling unit effectively distinguishes the sources of samples from different anatomical locations, providing an accurate sample partitioning basis for subsequent testing.

[0055] Furthermore, an anti-slip groove is provided at one end of the handle bar 1 away from the brush head 2 .

[0056] As attached Figure 2 As shown, the present application further proposes that the brush head 2 includes a core shaft 21 and a plurality of sampling wires 22 , the core shaft 21 is coaxially arranged at one end of the handheld rod 1 , and the plurality of sampling wires 22 are arranged on the core shaft 21 and are radially arranged.

[0057] The core shaft 21 is coaxially arranged with the handle 1 to form a rigid connection reference, ensuring axial force transmission during the sampling process. The multiple sampling filaments 22 are fiber bundles spirally arranged along the surface of the core shaft 21. Specifically, they can be made of nylon, polytetrafluoroethylene, or polyamide layered winding. A gap is formed between each sampling filament 22 to fix the core shaft and maintain structural stability. A gap is formed between two adjacent sampling filaments 22 to facilitate the collection of secretions.

[0058] Through the above technical solution, the present application solves the problem of insufficient sample volume caused by single-point sampling. The three-dimensional distribution structure of multiple sampling wires 22 forms multi-directional interception when contacting secretions. The core shaft 21 is used to fix multiple sampling wires 22 to prevent the sampling wires 22 from becoming loose due to deformation, thereby maintaining the structural stability of the brush head 2 while improving the single sampling efficiency.

[0059] As attached Figure 2 As shown, the present application further proposes that a spherical block is provided at one end of the core shaft 21 away from the handheld rod 1 , and the sampling wire 22 is located between the spherical block and the handheld rod 1 .

[0060] The spherical block refers to a hemispherical or quasi-spherical structure fixed to the end of the core shaft 21. Specifically, it can be made of the same material as the core shaft 21. The spherical block is mounted on one end of the core shaft 21 and its diameter can be larger than the diameter of the core shaft 21. The area between the spherical block and the handle 1 of the sampling wire 22 is the axial constraint space formed by the end surface of the spherical block and the end surface of the handle 1.

[0061] Specifically, when the handheld rod 1 drives the core shaft 21 into the cervix, the raised end surface of the spherical block forms a physical barrier, preventing the multiple sampling threads 22 wrapped around the core shaft 21 from slipping distally. As the sampling threads 22 deform upon contact with secretions, their radial expansion is constrained by the sidewalls of the spherical block, preventing axial displacement of the sampling threads 22 during repeated scraping. The roots of the sampling threads 22 are confined within a fixed spacing between the spherical block and the handheld rod 1, maintaining a preset winding density throughout operation and ensuring that each layer of sampling threads 22 effectively contacts the target area.

[0062] Through the above technical solution, the present application effectively prevents the sampling thread 22 from axial displacement or loosening during the collection operation, ensuring that the multi-layer sampling thread 22 remains stably deployed when in contact with cervical tissue. The limiting effect of the spherical block ensures that the sampling thread 22 is always in the optimal working position, improving the integrity of secretion collection while its smooth surface avoids mechanical damage to the cervical mucosa.

[0063] The present application further proposes that the core shaft 21 is a twisted steel cable, and a plurality of sampling wires 22 are arranged in the steel cable. The plurality of sampling wires 22 are arranged in a conical shape along the length direction of the core shaft 21 .

[0064] Arrangement along the length of the core shaft 21 refers to the radial distribution of the sampling filaments 22 along the extended axis of the core shaft 21. This can be achieved by sequentially arranging fiber filaments of different lengths on the core shaft 21, so that each layer of sampling filaments 22 can cover areas at different depths of the cervix. Conical arrangement refers to the radial projection of multiple sampling filaments 22 forming a geometric shape with a gradually decreasing outer diameter. This can be achieved by arranging tapered fiber layers circumferentially around the core shaft 21, so that the arrangement of the sampling filaments 22 matches the morphology of the human body cavity.

[0065] The steel cable is formed by folding and rotating a steel wire in half. The sampling wire 22 is located between the folded steel wires. The rotation of the steel wires causes the sampling wire 22 to rotate and be arranged radially. Then, by trimming, multiple sampling wires 22 can be arranged in a conical shape, which can achieve the fixation and radial arrangement of the sampling wires. At the same time, the rotational force between the steel wires can also be used to fix the sampling wire 22 to prevent the sampling wire 22 from detaching.

[0066] Through the above technical solution, this application improves the sample acquisition and coverage of a single sampling, reducing the discomfort caused to patients by multiple sampling operations; the conical structure design adapts to the characteristics of the human cavity, reduces the difficulty of sampling operations, and improves clinical detection efficiency.

[0067] The present application further proposes that the core shaft 21 is inserted into the interior of the hand-held rod 1 .

[0068] One end of the mandrel 21 is a steel cable, and a slot is provided at the bottom of the handle 1. The steel cable has an interference fit with the slot at the bottom of the handle 1, achieving axial positioning through physical crimping. A plug-in structure refers to an assembly method in which the mandrel 21 is embedded in the inner cavity of the handle 1 through an interference fit or a snap-fit structure. Specifically, the plug-in hole and the steel cable have an interference fit, forming a rigid connection between the mandrel 21 and the handle 1.

[0069] Specifically, the core shaft 21 is fixed inside the handheld rod 1 by plugging. When subjected to rotational or axial forces during the sampling process, the plug-in structure can limit the relative displacement between the core shaft 21 and the handheld rod 1. The friction force generated by the interference fit of the plug-in surface offsets the lateral load during the sampling operation, preventing the core shaft 21 from loosening and falling off. During assembly, the core shaft 21 is directly pressed into the predetermined depth of the inner cavity of the handheld rod 1 without the need for additional fixing glue or hot melt process. After assembly is completed, the core shaft 21 remains coaxial with the handheld rod 1, ensuring that the multi-layer sampling wire 22 wrapped around the core shaft 21 stably contacts the cervical area.

[0070] Through the above technical solution, the present application solves the problem of unstable connection between the brush head 2 and the handheld rod 1, preventing the core shaft 21 and the handheld rod 1 from relative displacement during the sampling process, resulting in sampling failure; the plug-in structure simplifies the assembly process, ensures the coaxiality of the core shaft 21 and the handheld rod 1, and enables the multi-layer sampling wire 22 to stably contact the target area, thereby improving the integrity and efficiency of cervical secretion collection.

[0071] As attached Figure 2 As shown, the present application further proposes that the flocking head 3 includes a connecting end 31 and a sampling end 32. The connecting end 31 is provided on the outer surface of the handheld rod 1, and the sampling end 32 is provided on the connecting end 31. The sampling end 32 is arranged in an arc shape to abut against the patient's uterine fornix.

[0072] The connecting end 31 is the base structure connecting the flocked head 3 to the handle 1. Specifically, it can be an injection-molded plastic base integrated with the outer wall of the handle 1. This structure ensures that the sampling end 32 maintains a predetermined spatial position during operation. The sampling end 32 is the head structure that collects secretions. Specifically, it can be injection-molded from an elastic polymer material to form a support frame with a preset curvature. The surface of the support frame is covered with flocked fibers. The curvature radius of this arc can be set to 12-18 mm to accommodate the physiological structure of the uterine fornix.

[0073] Specifically, the way the connecting end 31 is fixed to the outer wall of the handheld rod 1 eliminates the assembly gap caused by the traditional split connection, and maintains the spatial positioning accuracy of the sampling end 32 during the insertion of the swab. The geometric characteristics of the arc of the sampling end 32 are optimized by fitting anatomical data, and its center of curvature coincides with the physiological curvature axis of the fornix. When the swab is pushed to the target position, the outer surface of the sampling end 32 forms a surface contact with the mucosal tissue. The flocking fibers produce a directional lodging under the action of pressure, and the secretions are adsorbed in the gaps between the fibers through capillary action. The increase in contact area increases the amount of adhesion per unit time. The sampling end 32 and the connecting end 31 adopt a gradual transition design to avoid tissue damage due to sudden changes in cross-section.

[0074] Through the above technical solution, the present application realizes a one-time complete collection of uterine secretions. The effective contact area between the sampling end 32 and the mucosal tissue is increased so that the sample acquisition amount meets the detection requirements, avoiding repeated sampling operations caused by insufficient contact; at the same time, the adaptability of the arc structure reduces the time consumed by the operator in finding the sampling position.

[0075] The present application further proposes that the apex of the sampling end 32 is lower than the apex of the brush head 2 , and the distance between the side of the sampling end 32 away from the handheld rod 1 and the handheld rod 1 is greater than the maximum distance between the connecting end 31 and the handheld rod 1 .

[0076] Among them, the vertex of the sampling end 32 is lower than the vertex of the brush head 2, which means that the highest point of the flocking head 3 is lower than the highest point of the brush head 2. This can be achieved by adjusting the installation angle and curvature radius of the connecting end 31 of the flocking head 3, so that the flocking head 3 forms a downward arc when extending longitudinally, thereby avoiding blocking the working area of the brush head 2. The distance between the side of the sampling end 32 away from the hand-held rod 1 and the hand-held rod 1 is greater than the maximum distance between the connecting end 31 and the hand-held rod 1, which means that the outer surface of the sampling end 32 is always located on the side of the connecting end 31 away from the hand-held rod 1, so as to ensure that the sampling end 32 is in contact with the uterine foramen.

[0077] Specifically, when the sampling swab is inserted into the body, the brush head 2 preferentially contacts the cervix for sampling. At this point, the flocked head 3 automatically avoids the cervix because its apex is lower than that of the brush head 2. As the swab continues to penetrate the uterine fornix, the gradually expanding curved surface of the flocked head 3 conforms to the fornix's dome by expanding outward.

[0078] Through the above technical solution, the present application realizes the synchronous and interference-free collection of cervical and fornix secretions, ensuring that the flocking head 3 will not affect the cervical sampling operation of the brush head 2 while fully contacting the fornix tissue, effectively avoiding repeated sampling actions, and significantly improving the sample acquisition rate of a single sampling.

[0079] The present application further proposes that the diameter of the sampling end 32 is larger than the diameter of the connecting end 31 , the top of the sampling end 32 is a spherical surface, and the sampling end 32 is wrapped with flocking cloth for collecting secretions from the uterine fornix.

[0080] The larger diameter of the sampling end 32 than the connecting end 31 refers to a gradually expanding transition structure at the connection between the sampling area and the handle 1. This can be achieved by using a tapered or stepped diameter reduction structure to increase the contact surface of the sampling end 32. The spherical top refers to a smooth, rounded surface without sharp corners at the end of the sampling end 32. This can be achieved by injection molding or mechanical polishing to eliminate sharp edges.

[0081] Specifically, the sampling tip 32 enhances its fit with the fornix by expanding its contact area. Its spherical surface evenly distributes pressure when in contact with human tissue, preventing excessive localized pressure from causing mucosal damage. Flocking enhances liquid absorption through capillary action between fibers. The flexible fiber layer of the flocking fabric undergoes slight elastic deformation during contact, ensuring effective collection of secretions while minimizing mechanical irritation.

[0082] Through the above technical solution, the present application realizes the directional collection of secretions in the fornix of the uterus, which can not only obtain the complete sample in a single sampling operation but also avoid the patient discomfort caused by repeated insertion; the gradually expanding structure makes the secretions easier to remain in the fiber layer, and the spherical end prevents accidental scratching of the tissue during the sampling process.

[0083] Furthermore, an airbag is provided on the outer surface of the sampling end 32, and a flocked cloth is covered on the airbag. When sampling, the airbag can be inflated or deflated to make the flocked cloth fit against the patient's uterine fornix, thereby increasing the contact area and facilitating sampling.

[0084] As attached Figure 1 As shown, the present application further proposes that a notch 4 is provided on the handheld rod 1 , the notch 4 is located on the side of the flocking head 3 away from the brush head 2 , and the notch 4 is an annular groove.

[0085] The notch 4 is a localized recessed structure formed on the surface of the handle 1, which can be achieved through mechanical cutting or injection molding. This notch 4 weakens the local structural strength of the handle 1, creating a stress concentration area for the breaking operation. The cross-sectional shape of the annular groove can be semicircular or trapezoidal. This annular structure ensures that the direction of force applied during breaking is unrestricted, preventing the fracture surface from deviating from the predetermined position.

[0086] Specifically, when the brush head 2 and the flocking head 3 need to be placed in the test tube 5 after sampling, the operator applies a bending force at the annular groove position; the stress concentration effect of the annular groove causes the hand-held rod 1 to break at this location, and the fracture surface remains flat, avoiding burrs or fragments; the brush head 2 and the flocking head 3 completely enter the test tube 5 along with the end of the broken hand-held rod 1, and the remaining part of the hand-held rod 1 can be discarded separately; when the brush head 2 or the flocking head 3 does not fall into the test tube 5, the brush head 2 and the flocking head 3 can be pushed into the inside of the test tube 5 through the broken hand-held rod 1.

[0087] Based on the above technical means, the present application realizes standardized control of the sampling swab breaking operation, avoiding the risk of sample contamination caused by fracture surface deviation; the annular groove structure enhances the mechanical stability of the handheld rod 1 when it is broken, ensuring that the brush head 2 and the flocking head 3 are completely retained in the test tube 5, thereby improving the reliability of sample detection; this design simplifies the operation process of the sampling swab and reduces the technical requirements of the breaking operation for medical staff.

[0088] As attached Figure 3 As shown, the present application proposes a gynecological secretion detection device, including a test tube 5, a sample pre-processing module 6, a sample drop module 7, a test strip detection module 81, a staining pool module 82, a tangible component detection module 83 and an algorithm processing module 9.

[0089] Among them, the test tube 5 refers to a container for simultaneously storing the composite sample collected by the sampling swab brush head 2 and the flocking head 3; the sample pre-treatment module 6 refers to a device for dissolving, centrifuging and diluting the composite sample. Specifically, a rotary oscillator and a constant temperature heater can be used to achieve sample homogenization processing to ensure the consistency of the subsequent sample concentration test; the sample drop module 7 refers to a device for quantitatively transferring the processed sample to the test strip 8. Specifically, a micro peristaltic pump and a micropipette can be used to coordinately control the drop volume to achieve accurate sample transfer; the test strip detection module 81 is used to perform optical detection on the test strip 8; the staining pool module 82 refers to a container for staining and marking the test strip 8; the formed component detection module 83 refers to a device for optically detecting the stained test strip 8; the algorithm processing module 9 is used to complete the analysis of the detection results of the above-mentioned test strip detection module 81 and the formed component detection module 83.
