[0095] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0096] Reference below Figure 1-Figure 16 The mask 1000 according to an embodiment of the present application is described, comprising: a mask body 1; a breathing valve 2, which is fixed on the mask body 1; a sampling structure, which comprises: a pathogen adsorption portion 31, which is arranged on the inner side of the breathing valve 2 and is suitable for adsorbing pathogens in the exhaled gas; wherein the pathogen adsorption portion 31 is suitable for entering the sample collection tube 2000 to contact with the sample preservation liquid 2004 in the sample collection tube 2000.

[0097] Currently, samples are mainly collected through throat swabs and nasal swabs. This collection method not only causes discomfort to the sampled person, but the sampler also needs training on sampling techniques and procedures. The sampler also needs special protection to avoid infection. Overall, this collection method has high operating risks, high sampling costs and low efficiency.

[0098] According to the shortcomings of the current collection method, the present application envisions that a mask 1000 can be used, and a pathogen adsorption part 31 can be set on the mask 1000 to collect viruses. This can replace the method of collecting samples through throat swabs and nasal swabs, reducing the discomfort of the sampled person. However, if the pathogen adsorption part 31 is directly adhered to the inner surface of the mask 1000, on the one hand, the thickness of the mask body 1 will be increased, thereby increasing the feeling of stuffiness when worn; on the other hand, the pathogen adsorption part 31 needs to be cut or folded into a predetermined size and then immersed in the preservation liquid for preservation. Not only is the operation cumbersome, but also during the sampling and transfer of the pathogen adsorption part 31, the sampling personnel will have too much contact with the pathogen adsorption part 31, which will increase the risk of infection. At the same time, there is also a risk of contamination of the sample, which may affect the accuracy of the test results.

[0099] Based on the above considerations, in order to increase the pathogen adsorption part 31 without increasing the thickness of the mask body 1 and to facilitate the removal of the pathogen adsorption part 31, the present application sets a breathing valve 2 on the mask 1000, and places the pathogen adsorption part 31 inside the breathing valve 2. In this way, when sampling, it is only necessary to remove the pathogen adsorption part 31 and put it into the sample collection tube 2000, or directly move the pathogen adsorption part 31 into the sample collection tube 2000. The sampler does not need to directly contact the pathogen adsorption part 31, which reduces the risk of the sampler's operation and ensures the safety of the sampler.

[0100] Since the present application can use the mask 1000 to directly collect viruses in the wearer's exhaled gas, there is no need for a sampler to perform collection operations, and therefore there is no need for training on sampling techniques and processes. The mask 1000 of the present application can be used by multiple wearers to collect samples at the same time, thereby improving sample collection efficiency and saving manpower.

[0101] In order to ensure the accuracy of the collection of the pathogen adsorption part 31 and prevent the virus in the outside air from affecting the sample, the present application sets the pathogen adsorption part 31 on the inner side of the breathing valve 2, that is, the side close to the wearer, so that the pathogens in the exhaled gas can be sampled directly after the wearer breathes, preventing the virus in the outside air from affecting the sample, resulting in inaccurate test results, and causing unnecessary economic and human losses to medical equipment, medical personnel, and the person providing the sample.

[0102] According to the mask 1000 of the present application, by setting a pathogen adsorption part 31 in the breathing valve 2, the aerosol particles exhaled by the wearer can be collected while ensuring the comfort of the wearer, avoiding various discomforts of the wearer during the sampling process, effectively avoiding the risk of infection of the sampler during the sampling process and the risk of contamination of the sample, and realizing simultaneous sampling of multiple people, which greatly improves the sampling efficiency.

[0103] According to one embodiment of the present application, the breathing valve 2 is a one-way valve, and the breathing valve 2 is configured to be opened when the wearer exhales and closed when the wearer inhales.

[0104] In order to ensure the accuracy of the sample and prevent viruses in the outside air from affecting the sample, the breathing valve 2 of the present application is a one-way valve. When the wearer exhales, the breathing valve 2 is opened to collect the viruses in the wearer's exhaled gas into the pathogen adsorption part 31; when the wearer inhales, it is closed to prevent air from entering the pathogen adsorption part 31 from the breathing valve 2, thereby destroying the sample and affecting the accuracy of the results.

[0105] According to an embodiment of the present application, the breathing valve 2 includes: a valve housing 21 and a valve plate 22 .

[0106] Specifically, the valve housing 21 is provided with an exhaust hole; the valve sheet 22 is provided on the valve housing 21 and is configured to open the exhaust hole when the wearer exhales and close the exhaust hole when the wearer inhales.

[0107] The valve shell 21 is fixed on the mask body 1, and the gas exhaled by the wearer can be discharged through the exhaust hole on the valve shell 21. A valve sheet 22 is provided at the position of the exhaust hole to open or close the exhaust hole, which is specifically embodied as: the exhaust hole is opened when the wearer exhales and is closed when the wearer inhales.

[0108] According to one embodiment of the present application, the pathogen adsorption portion 31 is disposed on the inner side of the exhaust hole.

[0109] It should be noted that the "inside" in the present application can be understood as the direction close to the wearer's face side, and the "outside" can be understood as the direction away from the wearer's face side; the exhaust hole opens when the wearer exhales and closes when the wearer inhales. It can be considered that the pathogen adsorption part 31 is arranged close to the wearer's side and only collects viruses in the wearer's exhaled gas. If it is arranged on the outside of the exhaust hole, the pathogen adsorption part 31 will be exposed to the air, and it cannot be guaranteed whether the sample is only the virus exhaled by the wearer.

[0110] According to an embodiment of the present application, one end of the valve sheet 22 is disposed on the valve housing 21, and the other end of the valve sheet 22 can be selectively pressed against the valve housing 21 to open or close the exhaust hole. When the wearer exhales, the valve sheet 22 opens and the exhaust hole is in an open state; when the wearer inhales, the valve sheet 22 is pressed against the housing and the exhaust hole is in a closed state.

[0111] According to an embodiment of the present application, there are multiple exhaust holes and the multiple exhaust holes are arranged at intervals along the circumference of the valve housing 21, the valve plate 22 is annular in structure, and the inner end of the valve plate 22 is fixedly connected to the valve housing 21, and the outer end of the valve plate 22 can be selectively pressed on the valve housing 21 to open or close the multiple exhaust holes. The valve plate 22 can be a solid part, and the valve plate 22 is rotated out or opened to open when the wearer exhales, and the valve plate 22 is rotated back or pressed on the housing to close when the wearer inhales.

[0112] According to an embodiment of the present application, a plurality of micropores are provided on the valve sheet 22, and the micropores are configured such that when the wearer exhales, the aperture becomes larger and connected to the exhaust hole, and when the wearer inhales, the aperture becomes smaller until it is closed. The valve sheet 22 can be a chemical material, and when the wearer exhales, the aperture of the micropores on the valve sheet 22 becomes larger and connected to the exhaust hole, and when the wearer inhales, the aperture of the micropores on the valve sheet 22 becomes smaller until the exhaust hole is closed.

[0113] According to one embodiment of the present application, the valve housing 21 is detachably disposed on the mask body 1. Since the pathogen adsorption portion 31 is disposed on the inner side of the breathing valve 2, the pathogen adsorption portion 31 needs to be taken out for testing when collecting samples. The valve housing 21, as a part of the breathing valve 2, can be disassembled from the mask body 1, and then the pathogen adsorption portion 31 can be processed in the next step.

[0114] Specifically, the valve housing 21 is threadedly matched with the mask body 1. The valve housing 21 can be separated from the mask body 1 by rotation, and then the pathogen adsorption part 31 is processed in the next step.

[0115] According to one embodiment of the present application, the valve housing 21 is connected to the pathogen adsorption portion 31 .

[0116] According to one embodiment of the present application, the breathing valve 2 further includes: a valve cover 23, which is arranged outside the valve housing 21 and defines an exhaust space with the valve housing 21, and a vent hole connected to the exhaust space is arranged on the valve cover 23. The gas exhaled by the wearer is discharged from the exhaust hole, then passes through the exhaust space and finally discharged from the vent hole to the outside.

[0117] According to an embodiment of the present application, the valve cover 23 is also provided with a blocking cover which can selectively seal the air vent.

[0118] In the actual sampling process, it is difficult to ensure that the external environment is a sterile environment. In order to ensure the accuracy of the test results, it is expected that the viruses collected in the pathogen adsorption part 31 are all exhaled by the wearer. In order to improve the applicability of the mask 1000 to various test environments and improve the accuracy of the test results, a baffle is further provided on the valve cover 23, and the air hole can be closed or opened. The baffle is used to isolate the exhaust space from the outside air, thereby effectively preventing viruses that may exist in the outside air from entering the exhaust space, thereby improving the accuracy and reliability of the final test results.

[0119] Preferably, the barrier cover can be constructed as a rotating barrier cover, one end of which is arranged on the valve cover 23, and the other end of the barrier cover can be selectively pressed on the barrier cover to open or close the air hole; the barrier cover can also be made of a certain material, and the air hole can be closed by pulling a drawstring.

[0120] It should be noted that the blocking cover is not limited to the above examples. As long as the purpose of sealing and opening the air vents on the valve cover 23 can be achieved, it is within the scope of protection of the present application.

[0121] According to one embodiment of the present application, the valve cover 23 is detachably connected to the valve housing 21. Since the pathogen adsorption part 31 is arranged on the inner side of the breathing valve 2, the pathogen adsorption part 31 needs to be taken out for testing when collecting samples. After the valve cover 23 is removed from the valve housing 21, the valve housing 21 and the pathogen adsorption part 31 are left, and it is more convenient to handle the pathogen adsorption part 31.

[0122] According to an embodiment of the present application, the valve cover 23 is threadedly matched with the valve housing 21. The valve cover 23 is separated from the valve housing 21 by rotating the valve cover 23.

[0123] According to one embodiment of the present application, the valve cover 23 is connected to the pathogen adsorption portion 31 .

[0124] According to an embodiment of the present application, the valve plate 22 is disposed in the exhaust space, and a filter layer is disposed on the outer side of the valve plate 22 .

[0125] On the one hand, in order to ensure the accuracy of the test results, it is expected that the viruses collected in the pathogen adsorption part 31 are all exhaled by the wearer. On the other hand, in order to prevent the sample preservative liquid 2004 from leaking out of the sample collection tube 2000 and polluting the surrounding environment during the sample inspection process, the present application sets a filter layer on the outside of the valve plate 22, that is, a filter layer is set in the exhaust space. The filter layer has good sealing and filtering effects. On the one hand, it can prevent viruses in the external environment from contaminating the pathogen adsorption part 31. On the other hand, when the pathogen adsorption part 31 is placed in the sample collection tube 2000 containing the sample preservative liquid 2004, the sample collection tube 2000 can be closed to prevent the sample preservative liquid 2004 from splashing or being contaminated by the external environment.

[0126] According to one embodiment of the present application, the filter layer has a fluffy state and a compressed state. In the fluffy state, the filter layer is suitable for filtering the air entering from the air holes and in the compressed state, it has airtight and watertight properties.

[0127] In order to ensure that the wearer can breathe smoothly and the filter layer has good air permeability and filtering effect, the filter layer can be formed of compressible loose material. During the sampling process, the filter layer is in a fluffy state, which is suitable for filtering the air entering from the air holes, avoiding viruses in the external environment from contaminating the adsorption material, and at the same time alleviating the feeling of stuffiness when wearing a mask 1000; when sampling, the filter layer can be compressed into a waterproof and airtight sealing layer to avoid splashing of the sample preservation liquid 2004. The filter layer in this application can be flexibly switched.

[0128] According to one embodiment of the present application, the mask 1000 further includes: a tightening device, which is connected to the filter layer and is suitable for compressing the filter layer and sealing the air holes when tightened. The tightening device can be a pulling string, and the filter layer is pulled by the string to form a water-tight and airtight sealing layer.

[0129] According to an embodiment of the present application, a waterproof sheet is further provided outside the filter layer, and the waterproof sheet can be selectively pressed against the valve cover 23 to seal the air hole. The waterproof sheet can further enhance the waterproofness during sampling, prevent the sample preservation liquid 2004 from splashing out, and achieve the effect of sealing the sample collection tube 2000.

[0130] According to an embodiment of the present application, the breathing valve 2 is detachably mounted on the mask body 1. The valve housing 21 and the valve cover 23 included in the breathing valve 2 both have threaded structures, and can be connected and assembled by rotation.

[0131] According to one embodiment of the present application, the breathing valve 2 can be selectively installed on the sample collection tube 2000 to seal the inlet of the sample collection tube 2000 .

[0132] A threaded structure is provided on the inlet of the sample collection tube 2000, which can be matched with the breathing valve 2. After the valve shell 21 with the pathogen adsorption part 31 or the valve cover 23 with the pathogen adsorption part 31 is partially removed, it can be directly placed in the sample collection tube 2000, and the sealing of the sample collection tube 2000 is achieved by the threaded cooperation between the inlet of the sample collection tube 2000 and the valve shell 21 or the valve cover 23.

[0133] Preferably, the breathing valve 2 can be selectively threaded with the mask body 1 or the sample collection tube 2000. When the breathing valve 2 is threadedly matched with the mask body 1, the virus can be collected, and when the breathing valve 2 is threadedly matched with the sample collection tube 2000, the sample collection tube 2000 can be sealed.

[0134] According to one embodiment of the present application, a base 4 is provided on the mask body 1, and the breathing valve 2 is detachably mounted on the base 4. The base 4 plays a supporting and fixing role, and is connected to the mask body 1, and can prevent the pathogen adsorption part 31 from falling off from the breathing valve 2.

[0135] According to one embodiment of the present application, after the breathing valve 2 is removed from the mask body 1 , the pathogen adsorption portion 31 is adapted to move away from the breathing valve 2 under the action of an external force to contact the sample preservation solution 2004 .

[0136] After collecting the viruses in the wearer's exhaled breath, the sample needs to be tested, and then the pathogen adsorption part 31 with the virus needs to be taken out. In one method, the pathogen adsorption part 31 is still connected to the breathing valve 2, but is moved away from the breathing valve 2 under the action of external force, so that the pathogen adsorption part 31 can contact the sample preservation solution 2004.

[0137] According to one embodiment of the present application, after the breathing valve 2 is removed from the mask body 1 , the pathogen adsorption portion 31 is adapted to be separated from the breathing valve 2 under the action of an external force to contact with the sample preservation solution 2004 .

[0138] In another method, the pathogen adsorption part 31 is separated from the breathing valve 2 under the action of external force, so that the pathogen adsorption part 31 falls into the sample preservation liquid 2004 and contacts with the sample preservation liquid 2004 .

[0139] According to an embodiment of the present application, the sampling structure further includes: a fixing frame 32 , on which the pathogen adsorption portion 31 is disposed, for fixing the pathogen adsorption portion 31 .

[0140] According to one embodiment of the present application, a pathogen adsorption portion 31 is provided at the inner end of the fixing frame 32, and the outer end of the fixing frame 32 is provided inside the breathing valve 2, and the portion of the breathing valve 2 facing the outer end of the fixing frame 32 is constructed as an elastic area to deform and push against the fixing frame 32 when subjected to force.

[0141] It should be noted that the outer end here refers to the end away from the wearer, and the inner end refers to the end close to the wearer.

[0142] A pathogen adsorption portion 31 is provided on the end of the fixing frame 32 close to the wearer, which is used to collect viruses in the wearer's exhaled gas. The end of the fixing frame 32 away from the wearer is fixed on the base 4 or the breathing valve 2. There is an elastic area on the end of the fixing frame 32 away from the wearer. When the elastic area is pressed, the fixing frame 32 will move accordingly.

[0143] According to one embodiment of the present application, the inner end of the fixing frame 32 is provided with a pathogen adsorption portion 31, and the outer end of the fixing frame 32 extends out of the outside of the breathing valve 2 to form a pressing portion. Figure 11-Figure 12 As shown, the fixing frame 32 passes through the breathing valve 2, the inner end of the fixing frame 32 is provided with a pathogen adsorption portion 31, and the outer end of the fixing frame 32 forms a pressing portion. By applying force to the pressing portion, the fixing frame 32 with the pathogen adsorption portion 31 moves downward.

[0144] According to one embodiment of the present application, the fixing frame 32 includes: an inner fixing frame 321 and an outer fixing frame 322 separated from each other, the inner fixing frame 321 is connected to the breathing valve 2 and is suitable for being separated from the breathing valve 2 under the action of external force, the inner end of the inner fixing frame 321 is provided with a pathogen adsorption portion 31, the outer end of the outer fixing frame 322 extends out of the outside of the breathing valve 2 to form a pressing portion, and the inner end of the outer fixing frame 322 can selectively stop against the outer end of the inner fixing frame 321.

[0145] like Figure 1-Figure 3 As shown, by applying force to the external fixing frame 322, the external fixing frame 322 transmits the force to the internal fixing frame 321, so that the fixing frame 32 with the pathogen adsorption part 31 moves downward until it is separated from the breathing valve 2. In this way, the pathogen adsorption part 31 can be aligned with the inlet of the sample collection tube 2000, and after the pathogen adsorption part 31 is separated from the breathing valve 2, it directly falls into the sample collection tube 2000 with the sample preservation solution 2004, completing the sampling.

[0146] According to an embodiment of the present application, a mounting hole is provided on the breathing valve 2 , and at least a portion of the inner fixing frame 321 passes through the mounting hole and is interference fit with the mounting hole.

[0147] The part of the inner fixing frame 321 that passes through the mounting hole has an interference fit with the mounting hole, so that the inner fixing frame 321 can be stuck on the breathing valve 2. After pressing and applying force, the inner fixing frame 321 moves downward, thereby destroying the part of the inner fixing frame 321 that has an interference fit with the mounting hole. At this time, the inner fixing frame 321 has a clearance fit with the mounting hole, and the inner fixing frame 321 can fall freely downward.

[0148] It should be noted that the inner fixing frame 321 can be clamped on the breathing valve 2 by using the lower section to be clamped with the mounting hole, or by using the middle section to be clamped with the mounting hole. The outer end of the inner fixing frame 321 that extends out of the breathing valve 2 is long enough so that during the pressing process, the interference fit part can be completely separated from the mounting hole, allowing the inner fixing frame 321 to fall freely and smoothly.

[0149] According to an embodiment of the present application, a weak connection portion is provided between the inner fixing frame 321 and the breathing valve 2 , and the weak connection portion is suitable for being broken under the action of an external force to separate the inner fixing frame 321 from the breathing valve 2 .

[0150] like Figure 9-10 As shown, the sampling structure, the inner fixing frame 321 and the breathing valve 2 are separated from the mask body 1 together, and the weak connection part provided between the inner fixing frame 321 and the breathing valve 2 can be broken when force is applied; when the sample is transferred to the sample collection tube 2000, the weak connection part is broken by applying force to separate the sampling structure from the inner fixing frame 321 and the breathing valve 2. In this way, the sampling structure can be aligned with the inlet of the sample collection tube 2000, and after the sampling structure is separated from the inner fixing frame 321 and the breathing valve 2, it directly falls into the sample collection tube 2000 with the sample preservation solution 2004, completing the sampling.

[0151] According to an embodiment of the present application, a limiting portion is provided on the breathing valve 2 , and after the outer fixing frame 322 pushes against the inner fixing frame 321 to separate from the breathing valve 2 , the limiting portion is suitable for limiting the outer fixing frame 322 from moving toward the inner fixing frame 321 .

[0152] Since the external fixing frame 322 is exposed to the air and force needs to be applied by hands or other objects, in order to prevent the external fixing frame 322 from passing through the mounting hole and falling into the sample collection tube 2000 together with the internal fixing frame 321 to contaminate the sample, the present application sets a limiting portion on the breathing valve 2 to prevent the external fixing frame 322 from falling into the sample collection tube 2000 together with the internal fixing frame 321.

[0153] According to an embodiment of the present application, the inner fixing frame 321 and the outer fixing frame 322 are both configured as rod-shaped structures, and the limiting portion includes: a limiting block provided on the outer fixing frame 322 and a limiting groove provided on the breathing valve 2 and engaged with the limiting portion, and the diameter of the limiting portion is greater than the diameter of the inner fixing frame 321. The limiting groove and the limiting block cooperate to prevent the outer fixing frame 322 from passing through the mounting hole, so as to prevent it from falling into the sample collection tube 2000 together with the inner fixing frame 321.

[0154] According to an embodiment of the present application, a support plate is disposed at the inner end of the fixing frame 32 , a first through hole is disposed on the support plate, and the pathogen adsorption portion 31 is disposed on the support plate and covers the first through hole.

[0155] The location for installing the pathogen adsorption part 31 can be constructed in the form of a support plate, and multiple legs can be set on the support plate. The pathogen adsorption part 31 is installed on the upper surface or lower surface of the multiple legs in the support plate, and the first through hole can be the gap between the two legs. The virus in the wearer's exhaled gas passes through the first through hole and adheres to the pathogen adsorption part 31.

[0156] According to one embodiment of the present application, a support tube is provided at the inner end of the fixing frame 32, the inner end of the support tube is open, a second through hole is provided on the tube wall of the support tube, and the pathogen adsorption part 31 is provided on the support tube and covers the second through hole.

[0157] The location for installing the pathogen adsorption part 31 can be constructed in the form of a support tube, and the second through hole on the support tube can be set on the wall surface of the support tube. The pathogen adsorption part 31 is installed on the inner wall surface or the outer wall surface of the support tube. The viruses in the wearer's exhaled gas pass through the second through hole and adhere to the pathogen adsorption part 31.

[0158] It should be emphasized that the inner end of the fixing frame 32 is replaced by a supporting tube instead of a supporting plate. According to the different fixing frames 32, the pathogen adsorption portion 31 is also changed from a sheet to a cylinder. When the pathogen adsorption portion 31 is constructed in the form of a cylinder, the contact surface area is larger, forming a structure similar to a filter tip, which is more efficient in collecting viruses than the sheet-shaped pathogen adsorption portion 31.

[0159] According to one embodiment of the present application, the base 4 is configured as a cylindrical structure and an air inlet is provided at the bottom of the base 4, and the pathogen adsorption part 31 is suitable for blocking the air inlet. The air inlet allows the pathogen adsorption part 31 to pass freely, and the pathogen adsorption part 31 can fall from the air inlet into the sample collection tube 2000.

[0160] According to one embodiment of the present application, the inner end of the fixing frame 32 is disposed on the breathing valve 2 or the base 4 , and the outer end of the fixing frame 32 is provided with a pathogen adsorption portion 31 .

[0161] like Figure 4-Figure 6As shown, the inner end indicates the end close to the wearer, and the outer end indicates the end away from the wearer; the mask 1000 in the embodiment comprises, from the inside to the outside, a mask body 1, a breathing valve 2 or a base 4, a fixing frame 32, and a pathogen adsorption part 31.

[0162] According to one embodiment of the present application, the fixing frame 32 is configured as a fixing tube, the outer end of the fixing tube is open and the inner end of the fixing tube is provided with a third through hole, and the pathogen adsorption part 31 is provided at the inner end of the fixing tube and covers the third through hole. Viruses in the wearer's exhaled gas pass through the third through hole and adhere to the pathogen adsorption part 31. The purpose of opening the outer end of the fixing tube is to allow the pathogen adsorption part 31 to pass through and fall into the sample collection tube 2000.

[0163] According to an embodiment of the present application, the fixed cylinder is detachably arranged on the breathing valve 2 or the base 4. When sampling the sample, the fixed cylinder needs to be removed from the breathing valve 2 or the base 4 first to facilitate the next sampling operation.

[0164] Preferably, the fixed cylinder is fixedly connected with the breathing valve 2 or the base 4. When collecting samples, the fixed cylinder is fixedly connected with the breathing valve 2 or the base 4, and when sampling, the fixed cylinder is removed from the breathing valve 2 or the base 4.

[0165] According to one embodiment of the present application, a lifting portion 323 is provided on the fixed cylinder. The purpose of the lifting portion 323 is to provide a portion for the collector to hold and operate. The lifting portion 323 is at a certain distance from the pathogen adsorption portion 31, which can prevent the risk of infection of the collector on the one hand and prevent the sample from being contaminated by viruses that may exist on the hands on the other hand.

[0166] According to one embodiment of the present application, the fixed cylinder includes: a fixed cylinder body and a bottom wall portion arranged at the outer end of the fixed cylinder body, the bottom wall portion is provided with a third through hole, and the bottom wall portion is configured to be separated from the fixed cylinder body under the action of an external force. The pathogen adsorption portion 31 is installed on the bottom wall portion, and the sample collection tube 2000 can be placed at the lower end of the bottom wall portion. Under the action of an external force, the bottom wall portion and the pathogen adsorption portion pass through the third through hole and fall into the sample collection tube 2000, completing the sampling.

[0167] The specific process may be as follows: after the bottom wall portion with the pathogen adsorption portion 31 is taken out from the mask body 1, it is separated from the fixed tube body. When the sample is transferred to the sample collection tube 2000, the fixed tube body contacts the sample collection tube 2000, and the bottom wall portion with the pathogen adsorption portion 31 is poked by applying force with a cotton swab, so that the bottom wall portion with the pathogen adsorption portion 31 is separated from the fixed tube body, and the pathogen adsorption portion 31 falls into the sample collection tube 2000 with the sample preservation solution 2004, thereby completing the sampling.

[0168] According to one embodiment of the present application, the bottom wall is detachably arranged on the fixed barrel body. Preferably, the bottom wall is fixedly engaged with the fixed barrel body. When collecting samples, the bottom wall is fixedly engaged with the fixed barrel body, and when taking samples, the bottom wall is removed from the fixed barrel body.

[0169] According to one embodiment of the present application, an exhaust channel is provided in the breathing valve 2, and at least part of the sampling structure is provided in the exhaust channel. The sampling structure can collect viruses in the wearer's exhaled air in the exhaust channel.

[0170] According to one embodiment of the present application, a pathogen adsorption portion 31 is provided at the inner end of the fixing frame 32, and the outer end of the fixing frame 32 is connected to the breathing valve 2. At least a portion of the fixing frame 32 is suitable for being inserted into the sample collection tube 2000 and suitable for being broken under the action of external force.

[0171] like Figure 8-Figure 9 As shown, a pathogen adsorption portion 31 is installed at the inner end of the fixing frame 32. After the fixing frame 32 is broken under the action of external force, the pathogen adsorption portion 31 detaches from the fixing frame 32 and falls freely.

[0172] According to an embodiment of the present application, a strength weakening area is provided on the fixing frame 32 so as to break under the action of an external force.

[0173] It should be noted that the structural type of the strength weakening zone is not particularly limited, and those skilled in the art can select it according to actual needs. For example, in order to facilitate the breaking of the fixing frame 32, a breakable notch can be formed on the fixing frame 32, which is the strength weakening zone. When force is applied, the stress in the strength weakening zone is concentrated, thereby reducing the difficulty of breaking. The strength weakening zone can be constructed as an area with a smaller cross-section on the fixing frame 32, or it can be constructed as an area of ​​material that is easy to break, which is conducive to breaking under the action of external force.

[0174] According to one embodiment of the present application, the fixing frame 32 is constructed as a cylindrical structure and the outer diameter of the fixing frame 32 is smaller than the inner diameter of the sample collection tube 2000. In this way, the fixing frame 32 can be inserted into the sample collection tube 2000, and an external force is applied to break the fixing frame 32, which is beneficial to the collection of samples.

[0175] The specific operation is as follows: when the sample is transferred to the sample collection tube 2000, the fixing frame 32 together with the pathogen adsorption part 31 are taken out from the mask body 1, and then one end of the fixing frame 32 together with the pathogen adsorption part 31 is inserted into the sample collection tube 2000, and the fixing frame 32 is partially pressed against the wall of the sample collection tube 2000 and an external force is applied to break the fixing frame 32, and the pathogen adsorption part 31 falls into the sample collection tube 2000 with the sample preservation solution 2004, and the sampling is completed.

[0176] According to one embodiment of the present application, a pathogen adsorption portion 31 is provided at the inner end of the fixing frame 32, and the outer end of the fixing frame 32 is connected to the breathing valve 2, and the pathogen adsorption portion 31 is suitable for being cut by the cutting portion 2003 on the sample collection tube 2000 to be separated from the fixing frame 32.

[0177] During sampling, a sample collection tube 2000 is placed below the pathogen adsorption part 31. After the fixing frame 32 and the pathogen adsorption part 31 are removed from the mask body 1, the cutting part 2003 on the sample collection tube 2000 can cut off the pathogen adsorption part 31 on the fixing frame 32, and the pathogen adsorption part 31 directly falls into the sample collection tube 2000 below to complete the sampling.

[0178] According to an embodiment of the present application, the sampling structure further includes: a limiting member 33 , a mounting foot 34 and a force-bearing rod 35 .

[0179] Specifically, the limit member 33 is arranged on the valve body; there are multiple mounting feet 34 and the inner ends of the multiple mounting feet 34 are all connected to the outer periphery of the pathogen adsorption part 31; the outer end of the force-bearing rod 35 is constructed as a force-bearing end, and the inner end of the force-bearing rod 35 can selectively apply force toward the mounting feet 34 or the pathogen adsorption part 31 to cause the pathogen adsorption part 31 to deform.

[0180] According to an embodiment of the present application, the outer end of each mounting foot 34 is hinged to the limiting member 33 , and the force-bearing rod 35 is suitable for pushing against the pathogen adsorption portion 31 to deform the pathogen adsorption portion 31 .

[0181] like Figure 13-14 As shown, when sampling, the force-bearing rod 35 is pushed inward, and the force-bearing rod 35 applies force to the pathogen adsorption part 31, and the pathogen adsorption part 31 bulges inward and deforms. Then, the deformed pathogen adsorption part 31 is placed in the sample collection tube 2000 with the sample preservation liquid 2004, and the sampling is completed.

[0182] According to one embodiment of the present application, the outer end of each mounting foot 34 is connected to the inner end of the force-bearing rod 35, and the force-bearing rod 35 is suitable for pulling the outer end of each mounting foot 34 so that each mounting foot 34 is retracted under the push of the limit member 33 and the pathogen adsorption portion 31 is deformed.

[0183] like Figure 15-16 As shown, when sampling, by pulling the force rod 35 outward, the outer end of the mounting foot 34 moves outward along with the force rod 35, and the limiter 33 limits the distance that the mounting foot 34 moves outward. Since there is a gap between the limiters 33, part of the mounting foot 34 passes through and is retracted under the push of the limiter 33, and the pathogen adsorption portion 31 bulges inward and is deformed. Then, the deformed pathogen adsorption portion 31 is placed in the sample collection tube 2000 with the sample preservation solution 2004, and the sampling is completed.

[0184] According to an embodiment of the present application, the limiting member 33 is constructed as an annular limiting ring. There is a gap between the limiting rings, which can limit the installation legs 34 from moving outward and can also play the role of retracting the installation legs 34.

[0185] According to an embodiment of the present application, the pathogen adsorption part 31 is connected to the fixing frame 32 through a water-soluble material layer.

[0186] When sampling, the pathogen adsorption part 31 can be sealed together with the fixing frame 32 in the sample preservative liquid 2004. Since the sample preservative liquid 2004 is mostly a water-based preservative liquid, the water-soluble material layer of the pathogen adsorption part 31 can be dissolved in the sample preservative liquid 2004 by shaking the sample collection tube 2000, thereby separating the pathogen adsorption part 31 from the fixing frame 32, further simplifying the sampling operation and significantly shortening the sampling time.

[0187] According to the sample collection tube 2000 in the embodiment of the present application, it includes: a collection tube body 2001 and a cover body 2002 .

[0188] Specifically, the collection tube body 2001 has an open mouth and is provided with sample collection liquid inside; the cover body 2002 is detachably provided on the collection tube body 2001 to close or open the open mouth; wherein a cutting portion 2003 suitable for cutting the pathogen adsorption portion 31 is provided in the sample collection tube body 2000.

[0189] Since the valve shell 21 has a threaded structure, it can directly cooperate with the threaded structure on the collection tube body 2001, replacing the cover body 2002 to close the open mouth on the collection tube body 2001, and the pathogen adsorption part 31 on the valve shell 21 can be cut by the cutting part 2003 in the sample collection tube 2000 body to separate the pathogen adsorption part 31 from the valve shell 21; there is no need to contact the pathogen adsorption part 31 too much, thereby reducing the risk of infection for the collector.

[0190] According to one embodiment of the present application, the cutting portion 2003 is disposed on the inner circumferential wall of the collection tube body 2001. Generally, the cover 2002 is partially inserted into the collection tube body 2001 to achieve sealing of the collection tube body 2001, so the cutting portion 2003 is disposed on the inner circumferential wall of the collection tube body 2001 to facilitate separation of the pathogen adsorption portion 31 on the valve housing 21.

[0191] According to one embodiment of the present application, the cutting portion 2003 is disposed adjacent to the opening. The sample preservation liquid 2004 is stored at the bottom of the collection tube body 2001. In order not to contaminate the sample preservation liquid 2004 and ensure the accuracy of the result, the cutting portion 2003 is disposed adjacent to the opening and away from the sample preservation liquid 2004. After cutting, only the pathogen adsorption portion 31 falls into the sample preservation liquid 2004, which is beneficial to the accuracy of the sample result.

[0192] According to an embodiment of the present application, there are multiple cutting portions 2003 and the multiple cutting portions 2003 are arranged at intervals along the circumference of the collection tube body 2001. The multiple cutting portions 2003 are conducive to separating the pathogen adsorption portion 31 on the valve housing 21.

[0193] According to the pathogen collection device in the embodiment of the present application, it includes: a sample collection tube 2000 and the above-mentioned mask 1000.

[0194] Specifically, a sample preserving liquid 2004 is provided in the sample collection tube 2000 ; the pathogen adsorption portion 31 on the mask 1000 is suitable for entering the sample collection tube 2000 to contact the sample preserving liquid 2004 in the sample collection tube 2000 .

[0195] In the description of the present application, it should be understood that the terms "inside", "outside", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
