Description

Technical Field

[0001] This invention relates to a liquid collector. More specifically, it relates to a liquid collector pre-configured to support a liquid delivery device for nasal irrigation. More specifically, it relates to a liquid collector pre-configured to support a liquid delivery device for nasal irrigation and for collecting nasal secretions mixed with the delivered liquid. Background Technology

[0002] Upper respiratory tract infections can be diagnosed by analyzing nasal secretions collected from the nasopharynx or olfactory region using a swab with a sterile cotton swab attached to the appropriate end. The swab must be flexible. During the procedure, the swab is inserted into the nostril and pushed horizontally to reach the nasopharynx, or upwards to reach the olfactory region, until resistance is encountered. After determining that the resistance is determined by the swab reaching the area to be sampled, the swab is gently rotated to locally remove the biological material composed of nasal secretions. The swab is then withdrawn, and the cotton end is inserted into a sterile container for preservation and transport to the laboratory. The removed biological material is then analyzed after microbial culture or other tests to isolate and identify pathogens.

[0003] Based on the above description, it is strongly recommended that swab examinations be performed by a professional operator who is familiar with nasal anatomy and can identify the anatomical structures of the patient's nasal cavity. This allows the operator to determine whether it is better to collect nasal secretions from the nasopharynx or the olfactory region, to protect the patient's nasal mucosa, and to determine the most effective method for sample collection.

[0004] In emergency situations, such as, but not limited to, a full-blown pandemic, the number of people awaiting testing far exceeds the number of skilled operators capable of performing swab tests in the nasopharynx or olfactory region. On the one hand, there is a clear risk that the sample size will be too small to provide rapid and reliable visualization of the infection level; on the other hand, there is a risk that the information obtained from swab analysis may not accurately reflect the infection status. In both cases, the resulting situation is highly unsatisfactory because public health is threatened. Furthermore, if swab tests are to be performed on individuals who already exhibit symptoms of infection, operator safety must be considered. In these situations, operators must wear personal protective clothing and equipment that fully covers their bodies; on the other hand, given that such clothing / equipment is disposable, this significantly increases the costs associated with operator-related testing and examination activities, in addition to being subject to supply chain risks.

[0005] Examples of collectors according to the preamble of claim 1 are known from WO 2019 / 091159 A1, US 2009 / 108097A1, WO 2010 / 12686A1, US 2017 / 028144A1, US 2010 / 1525653A1, CN 208 017 763U and CN 2 474 138 Y.

[0006] In light of the above, there is a need for a practical and cost-effective device that allows for the autonomous and efficient collection of biological samples from the nasopharynx or olfactory region, thus eliminating the need for specialized operators and thereby removing the risk of infection for healthcare personnel involved in the analysis. Clearly, in addition to limiting and, where possible, overcoming the typical drawbacks of the aforementioned known techniques, the use of such a device would allow for the definition of new operating procedures to sample nasopharyngeal / olfactory nasal secretions from large populations for analysis in a completely safe and highly reliable manner. In particular, the device allows patients to collect nasal secretions mixed with a cleaning solution themselves, thereby eliminating the risk of third-party infection and error.

[0065] Before describing the preferred embodiments of the invention or their details in detail, it is useful to clarify that the relative scope is not limited to the specific embodiments described below. The disclosure and description in this document are illustrations and explanations of one or more currently preferred embodiments and variations, and those skilled in the art will understand that various changes can be made in terms of design, organization, sequence of operations, mode of operation, structure of equipment and location, and use of method and mechanical equivalents without departing from the spirit of the invention.

[0066] Furthermore, it should be understood that the purpose of the accompanying drawings is to clearly illustrate and disclose the currently preferred embodiments to those skilled in the art, and not to illustrate how the embodiments should be implemented in reality, nor to present a true representation of the final product; rather, the drawings may include simplified conceptual views to facilitate understanding or allow for easier and faster interpretation. Moreover, the relative dimensions and arrangements of the components may differ from those shown, and still function within the spirit and scope of the invention.

[0067] Various designations such as “up,” “down,” “left,” “right,” “front,” and “rear” refer only to interpretations made in conjunction with the accompanying drawings, and the orientation of components may differ, for example, during transport and production, as well as during operation. Because many different embodiments can arise in the context of the concepts taught herein, and because various modifications can be made to the embodiments described herein, the details provided below must be interpreted as illustrative and non-limiting in relation to the spirit of the invention.

[0068] exist Figure 1 In the diagram, the number 1 generally represents a liquid collector, which is provided with a first concave body 10, which is symmetrically shaped into a funnel shape with respect to the vertical centerline plane MT that cuts across it. Figure 3 This can be seen better in the image. The first body 10 laterally defines the volume of its cross-section decreasing from the annular edge 12, and has an outlet 11 at the bottom, which is provided with a hole for liquid to pass through. This hole is located at the lowest point of the first body 10, preferably at the center, but not limited to that location.

[0069] For details, please refer to the following: Figure 1 , 2 5. Collector 1 has a connecting member 100 at its bottom, which can be used to selectively connect a removable collection member 102 to the first body 10, particularly below the outlet 11, to receive liquid from the first body 10 through the outlet 11. The connecting member 100, in combination or alternatively, includes a first cylindrical portion 130 positioned below an annular edge 12, defining the outlet 11 at its outer periphery and terminating at a first hook portion 132 and / or a second hook portion 134. The first hook portion 132 is provided with a cylindrical seat extending a corresponding length, the lower edge of which is formed to hydraulically seal with the upper edge of a vial 102' for collecting the liquid to be analyzed. Figure 1 and 2 The second hook portion 134 is coaxial with the outlet 11 and is provided with a cylindrical seat that extends to a corresponding length. Its lower edge is shaped to accommodate the test tube 102 by means of a hydraulic seal through the corresponding upper edge. Figure 4 For practical purposes, Figure 1-5 The embodiment of collector 1 shown has both a cylindrical portion 130 and a second hook portion 134 for test tube 102”, but the scope of the invention is not limited to this embodiment.

[0070] For details, please refer to the following: Figure 5The cylindrical seats of the first hook portion 132 and the second hook portion 134 have at least one longitudinal rib 104 with a semi-cylindrical cross-section and a respective rounded end at the bottom. Their function is to facilitate insertion of the vial 102' or test tube 102" respectively, thereby improving the ability to hold the vial 102' and the test tube 102" respectively. Furthermore, the cylindrical seats of the first hook portion 132 and the second hook portion 134 each have at least one axial support 108 at the bottom for the edge of the vial 102' and the test tube 102" respectively. It should be noted that the rib 104 and the support 108 function to hold the inner sleeve of the vial 102' and the test tube 102" and to hold the free edges of the openings of the vial 102' and the test tube 102" respectively, which are separated from the bottom of the cylindrical seat. This feature allows air contained in the vial 102' and the test tube 102" to escape, which would otherwise prevent the containers from being filled with liquid mixed with nasal secretions received from the first concave body 10 through the outlet 11.

[0071] The first body 10 also has two sides 124, and the collector 1 includes a first front wall 120 and a second rear wall 122, which are symmetrically formed with respect to the centerline plane MT and are supported facing each other between the two sides 124 by an annular edge 12 in a hydraulically sealed manner. The first wall 120 and the second wall 122 are connected on one side 124 by a side wall 126.

[0072] For details, please refer to the following: Figure 1 , 3 5. The second wall 122 is defined at its top by a concave curved section 1220, which is shaped to couple with the facial anatomical portion disposed between the user's upper lip and nose in use. Furthermore, the first wall 120 extends from the annular edge 12 to a greater extent than the second wall 122, and the curved section 1220 is laterally defined by two symmetrically shaped corner portions 1222, which are designed in use to laterally define the nostrils of the nose. The corner portions bulge relative to the central portion of the second wall 122 and are preferably, but not exclusively, pointed, although they may be rounded without departing from the scope of the invention.

[0073] refer to Figure 1-5 The collector 1 includes a first interface 1240 facing the sidewall 126, which extends in a given direction D transverse to the centerline plane MT. The first interface 1240 is shaped to receive the supply member 30. Figure 6-9The supply component is designed to dispense liquid between the first wall 120 and the second wall 122 in the form of an atomized or liquid jet, in the direction opposite to outlet 11, and thus upward, via a dispenser, preferably but not exclusively a nasal nozzle 34, which is specifically shaped to adhere to the corresponding nasal vestibule in a hydraulically sealed manner by simply applying slight pressure laterally across the nasal vestibule. In the drawings, the nozzle is shown as a dome-shaped body, but the shape of this embodiment is merely illustrative and not intended to limit the scope of the invention.

[0074] Specifically, the supply component 30 includes a syringe 36, which is provided with a nasal nozzle 34, which is supported longitudinally or laterally by the outlet nozzle (known but not shown) of the syringe 36 according to the requirement of nasal cleaning with a given liquid in the form of atomization or liquid jet.

[0075] refer to Figure 1 The first wall 120 and the second wall 122 are divided into at least the first side 124A of two sides 124, forming a first opening 128 above the first body 10. Specifically, the first interface 1240 is supported by the first side 124A transversely to the centerline plane MT, and faces the first body 10 through the first opening 128.

[0076] The first interface 1240 has a retaining element 1242 for holding the liquid delivery member 30, particularly the syringe 36, at the opposite first opening 128 on the first side 124. More specifically, the retaining element 1242 consists of a protrusion 1242 (designated by the same reference numerals for practical purposes) that is at least partially cylindrical, having an angle greater than 180°, disposed at the junction between the first interface 1240 and the first side 124 to hold the syringe 36 in any longitudinal position determined by the user.

[0077] The use of collector 1 described above is easy to understand and requires no further explanation. However, for details, please refer to [link / reference needed]. Figure 4-9 It is necessary to explain that once the vial 102' (used for analysis) Figure 5-9 The first hook portion 132, or test tube 102', has been connected to the internal hollow cylindrical portion 130. Figure 4The syringe 36, already connected to the second hook portion 134 and filled with cleaning fluid, and equipped with a corresponding nasal nozzle 34, is positioned inside the first interface 1240. The user can grasp the collector 1 through the cylindrical portion 130, move the collector 1 closer so that the second wall 122 is between his / her upper lip and nose, and slide the syringe 36 longitudinally in direction D until it is positioned so that the nasal nozzle 34 faces one of the two nostrils for at least the first cleaning of the nasal cavity. At this point, the syringe 36 is blocked longitudinally and laterally by the protrusion 1242. Before proceeding, the collector 1 must be pressed further upward until the nasal nozzle 34 hydraulically seals against the nasal vestibule of the selected nostril to maximize the possibility that the liquid in the syringe 36 is completely delivered into the nasal cavity. At this point, the second wall 122 must be gently pressed against the skin between the upper lip and the nasal cone, and the head tilted forward, keeping the edge 12 of the first body 10 of the collector 1 substantially horizontal, to maximize the possibility that the liquid in the syringe 36, once expelled from one or both nostrils, remains inside the first body 10, while splashed liquid cannot leak from above the first wall 120 or from the opening 128 obtained from the first side 124 during the expulsion phase. If any liquid splashes onto the first or second walls 120 / 122 or onto the skin between the user's upper lip and the nasal cone, it will fall back into the first body 10 under gravity without any external intervention.

[0078] At this point, the piston of syringe 36 can be operated to partially or completely empty the liquid contained therein, and as described above, it is delivered into the nasal cavity through the selected nasal vestibule.

[0079] Clearly, if the volume of liquid contained in syringe 36 is smaller than the volume of the nasal cavity, all liquid delivered to the nasal cavity will remain within the cavity until syringe 36 is completely emptied, and as long as the nasal nozzle 34 remains in the selected nasal vestibule in a hydraulically sealed manner. On the other hand, if the volume of liquid contained in syringe 36 is larger than the volume of the nasal cavity, when the nasal cavity is completely filled, the excess liquid will begin to spontaneously flow through the nasopharynx to the other nostril and from there into the first body 10; then from there into the vial 102' or test tube 102' through outlet 11. In both cases, but especially in the case where the volume of liquid contained in syringe 36 is smaller than the volume of the nasal cavity, the delivered liquid and the nasal secretions removed therefrom are only permitted after the nasal nozzle 34 is removed from the nasal vestibule engaged in a hydraulically sealed manner. Expelled from inside the nasal cavity. Considering that even minimal movement of the nasal nozzle 34 relative to the engaged nostril may cause fluid contained in the corresponding nasal cavity to leak out, in order to reasonably ensure that the cleaning fluid flows completely into the first body 10 and freely flows from there through the outlet 11 into the vial or test tube 102 by gravity, the user must first keep his / her head in a slightly forward tilted position and keep the edge 12 of the first body 10 of the collector 1 horizontal, with the curved section 1220 of the second wall 122 in hydraulic seal contact with the skin between the nose and upper lip. Since the syringe 36 cannot be slid to remove the nasal nozzle 34 from the nasal vestibule, to avoid damage, the user can use the protrusion 1242 located at the connection of the first interface 1240 as a hinge point for the syringe 36. In fact, the protrusion 1242 applies circumferential pressure to a given portion of the syringe 36 located between the first interface 1240 and the first body 10, allowing it to apply pressure to the syringe as... Figure 9 The nasal nozzle 34 is hinged during rotation to disengage from the corresponding nasal vestibule.

[0080] As previously described, with the minimal movement of the nasal nozzle 34 from the operating position within the nostril to a lower position toward the outlet 11, nasal secretions will mix with the liquid contained in the nasal cavity and flow out, subsequently being collected in a vial 102' or test tube 102" without the loss of a single drop of the mixture. The first wall 120, always held in front of his / her nose by the user, will prevent any droplets from flowing out of the first body 10, splashing into the surrounding area, and posing a risk to anyone intentionally or unintentionally approaching the user performing nasal irrigation.

[0081] As described above, the collector 1 is particularly useful when the user must perform nasal irrigation themselves. Considering that the irrigation solution always contains nasal secretions, if the collector 1 is made of plastic or pressed cardboard for single use, it is also particularly suitable for nasal irrigation of individuals with infectious diseases, such as, but not limited to, the coronavirus “SARS-COVID-19,” for treatment or for collecting nasal secretions removed from the irrigation solution for analysis. Clearly, using the collector 1 in this way allows for the collection of nasal secretions from any part of the nasal cavity without operator intervention, and the examination of any location within the nasal cavity for the presence of viral particles. In fact, once one of the two nasal cavities has been irrigated and the nasal nozzle 34 has been removed from the corresponding nostril, the user can slightly lift his / her head to release the nasal nozzle 34, thus allowing the syringe 36 to slide freely until the nasal nozzle 34 faces the nasal vestibule of the other nostril, completing the irrigation operation as described above. It should be emphasized that sampling nasal secretions using the collector 1 is particularly inexpensive.

[0082] Finally, it is obvious that modifications and variations can be made to the collector 1 described and illustrated herein without departing from the scope of the invention.

[0083] For example, to maximize the safety of collector 1 and prevent liquid particles from flowing out from the top above the first wall 120, see specific references. Figure 10 and Figure 11 The wall can be modified by adding a conical cap member 129, which is shaped to include a nose cone from the opposite root to the corresponding upper edge BS. Naturally, the cap member 129 can snap onto the first wall 120 at the corresponding upper edge 125.

[0084] refer to Figure 12 and 13 Another embodiment of the collector 1 is shown, which is designed to perform nasal irrigation using a syringe 36, the volume of which is more suitable for the nasal cavity volume of the user to be treated, but has two syringes of different volumes. In this case, the collector 1 has a second interface 1240' aligned with the first interface 1240, and its dimensions are different from those of the first interface but similar in geometry, taking into account the geometry of the syringes of different volumes. Figure 12 and 13This structural feature of the collector 1 allows for the use of two syringes 36 of different sizes within the same collector 1 to treat patients with different nasal cavity volumes, without the need for pre-classification of patients based on this feature before treating each patient. The second interface 1240 is supported by a second side 124B of the two sides 124, wherein, taking into account the size of the second interface 1240, the first wall 120 is separated from the second wall 122 by a second opening 128' that is identical or geometrically similar to the first opening 128. Furthermore, it should be emphasized that, with reference to... Figure 12 and 13 The described collector 1 has the same characteristics as... Figure 1-9 The collector 1 is the same as the connecting member 100.

[0085] refer to Figure 14 and 15 The collector 1 shown has a first wall 120 and a second wall 122 connected to the side wall 124 via a side wall 126. Figure 1-9 The situation is the same for collector 1. However, in this case, the first wall 120 and the second wall 122 are geometrically identical and symmetrically formed with respect to the centerline plane MT of the first body 10, and therefore are also identical in height. Furthermore, the first wall 120 and the second wall 122 each have identical concave surfaces 121 and 123 facing opposite sides (outwards) relative to the outlet 11. Therefore, each of the first wall 120 and the second wall 122 is defined by a curved section, which, for practical purposes, is similar to... Figure 1-9 The concave segment 1220 of collector 1 is also numbered 1220, and subsequently, similarly, is laterally defined by corner portions 1222 that are identical in geometry and size. It may be noted that the first wall 120 and the second wall 122 are separated by an opening 128 on the side opposite to the side wall 126, and have an interface with the same geometry as the first interface 1240, thus it... Figure 14 and Figure 15 The number in and in Figure 1-9 The reference numerals used are the same. Similarly, in this case, the first interface 1240 is provided with a protrusion 1242. Finally, Figure 14 and 15 Collector 1 has the same Figure 1-9 The same connecting component 100.

[0086] As mentioned above, Figure 14 and 15The first wall 120 and the second wall 122 (of the same size and geometry) of the collector 1 are designed to press against the skin between the user's upper lip and nasal cone during cleaning and drainage, thereby allowing the positioning of the corresponding first interface 1240 where the syringe 36 is located, thus allowing the positioning of the corresponding nasal nozzle 34, indiscriminately facing the right or left nasal vestibule, or sequentially by simply rotating the collector 1 180°.

[0087] refer to Figure 16-20 The image shows a collector 1, symmetrical with respect to the transverse centerline plane MT, and having a first wall 120 and a second wall 122 connected at side 124 by the same opposing sidewalls 126, which are also symmetrically shaped with respect to the centerline plane MT of the first body 10. Specifically, in this case, the connecting member 100 has been modified, and the first cylindrical portion 130 located below the annular edge 12 is missing, making the first body 10 visible; furthermore, the first interface 1240 and the second interface 1240' are replaced by a third interface 1240" which is supported at the bottom by the first body 10, parallel to the centerline plane MT next to the outlet 11, with the conduit 110 corresponding to the outlet 11, forming part of the modified connecting member 100. Also in this case, the third interface 1240" is pre-configured to accommodate the syringe 36, but the corresponding outlet nozzle protrudes inside the first body 10 to directly or through the corresponding mouthpiece 1246 via the third interface 1240" Figure 17a The extended portion 1244 supports the nasal nozzle 34 within the first body 10. The outlet conduit 110 and the third interface 1240 preferably, but not exclusively, share a portion of their respective outer casings to integrally define the “8”-shaped body in cross-section. Figure 18 It can be easily seen that, according to Figure 16-20 The collector 1 can be accommodated inside the corresponding conduit 110, such as Figure 16 and 17a The second syringe 36 shown or as Figure 17b The test tube 102” shown does not change the scope of the invention. Similarly, in this case, to improve the ability to hold the vial or test tube 102” and to expel any air contained therein, the conduit 110 and the third interface 1240” have at least one longitudinal rib 104 and at least one support 108, as referenced. Figure 1-9 The implementation of collector 1 shown Figure 5 As stated above. Figure 18 In the middle, evenly distributed ribs 4 protrude from the inner sleeve of the conduit 110 and from the inner sleeve of the third interface 1240”, and the support 106 has the same number of protrusions 108 offset relative to the ribs 104, and the features described do not represent a limitation on the scope of the invention.

[0088] As described above, the first wall 120 and the second wall 122 (of the same size and geometry) are designed to press against the skin between the user's upper lip and the nasal cone, thereby allowing the positioning of the third interface 1240, on which the syringe 36 is located, and thus allowing the positioning of the nasal nozzle 34, facing either the right or left nasal vestibule indiscriminately, or by simply rotating the collector 1 180° sequentially.

[0089] refer to Figure 21 and 22 Collector 1 can be relative to Figure 16-20 Collector 1 is modified, specifically referring to the corresponding first wall 120, which can be raised and has a similar function. Figure 10 and 11 The cover 129, wherein the first wall 120 relative to the first body 10 may be flat, concave or convex, without modifying the scope of the invention.

[0090] The difference is that Collector 1 can be specifically referenced. Figure 23-26 Modifications were made to keep the first body 10 visible, and the connecting member 100 was modified to define a unique path through which the cleaning fluid can be delivered and discharged once the nasal cavity is sprayed. Specifically, the path is implemented in the hole defining the outlet 11. For orderly operation, the first body 10 supports a fourth interface 1240"' at its bottom around the hole of the outlet 11. The fourth interface 1240"' is provided with a housing member 112 having a longitudinal window and is pre-configured to accommodate a bidirectional hydraulic selector 114. Figure 25 The bidirectional hydraulic selector is provided with first and second alignment conduits 115 and 116, and a conduit 117 transverse to the other two conduits, as well as a switching valve 118. The first alignment conduit 115 engages the orifice of outlet 11 in use and supports the nasal nozzle 34 within the first body 10. The other alignment conduit 116 engages the housing member 112 and can accommodate within it the neck of a test tube 102' supported by the lower edge of the housing member 112, which is part of a housing member 100 modified for this type of collector 1. The remaining transverse conduit 117 engages with the outlet nozzle of syringe 36. Valve 118 is designed to selectively determine the connection between the first alignment conduit 115 and the transverse conduit 117 (conditions for delivery of cleaning fluid through the nasal nozzle 34) and the connection between the first alignment conduit 115 and the second alignment conduit 116 (outlet conditions) without removing the nasal nozzle 34 from the edge of the nostril sprayed with liquid. Naturally, if the test tube 102” is replaced by the vial 102’, the operation of the device will be the same, the vial 102’ being properly provided with an adapter 103 for stably connecting it to the outside of the housing member 112.

[0091] In the same case, the first wall 120 and the second wall 122 (of the same size and geometry) are both designed to press against the skin between the user's upper lip and the nasal cone, thereby allowing the positioning of the syringe 36, and thus allowing the positioning of the corresponding nasal nozzle 34, facing the right or left nasal vestibule indiscriminately, or by simply rotating the collector 1 180° sequentially.

[0092] refer to Figure 27-29 This illustrates another embodiment of the invention, which may be considered as a reference. Figure 1-9 In a variant of the described version, liquid is delivered by a nasal nozzle 34, which is supplied by a syringe 102” housed within a first interface 1240, which is the only interface in this embodiment. Figure 28 As shown, and Figure 9 As shown more clearly in the diagram, the connecting member 100 includes only the second hook portion 134 to accommodate the test tube 102 below the outlet 11. Thus, once the nasal cleansing has been performed, the liquid containing the removed nasal secretions flows into the first body 10 and from there through the outlet 11 to the test tube 102 contained within the second hook portion 134.

[0093] refer to Figure 30-32 , Figure 27-29 The collector settings are as follows Figure 12 and 13 The two interfaces shown are 1240 and 1240'.

[0094] Figure 33-35 It shows Figure 27-29 The modified version of collector 1 shown here, wherein the first body 10, and the first front wall 120 and the second rear wall 122 are divided in two by a partition 40, which divides the volume defined by the first body 10 into two parts and is further defined at the top by a straight edge 41 that connects the two parts of the annular edge 12 of the first body 10, thus being transverse to a given direction D. Therefore, when collector 1 is configured with a corresponding vertically oriented second hook portion 134, the straight edge 41 is horizontal. The division defined by the partition 40 within the first body 10 requires the outlet 11 to move laterally relative to the partition 40 on the side opposite the interface 1240, and also requires the second hook portion 134 to move laterally for obvious structural reasons.

[0095] Figures 36-38 It shows Figures 33-34A modified version of the collector 1 shown, wherein the outlet 11 is coupled to the outlet hole 11' on the side opposite to the partition 40, the outlet hole 11' leading to another second hook portion 134' for another test tube 102", can be used to collect liquid that may flow from the nasal nozzle 34 into the free nostril once the liquid is delivered by the syringe 36 supported by the interface 1240, if the liquid portion must be collected in an uncontaminated state for subsequent inspection in some way.

[0096] exist Figures 39-41 In, it is shown Figures 36-38 A variation of the embodiment in which another second hook portion 134' is replaced by a cylindrical container 50, which can be used to collect any portion of the liquid that may flow from the nasal nozzle 34 into the free nostril once the liquid has been delivered by the syringe 36 supported by the interface 1240. It is particularly useful to equip the collector 1 with container 50 (which can be equipped with any embodiment of the collector described above) if it is desirable to collect the portion of the liquid flowing from the nasal nozzle 34 into the free nostril, but it is not essential that it be collected uncontaminated in a test tube, for example, for subsequent dispersion in a given environment.

[0097] exist Figure 42 and 43 In, it is shown Figures 39-41 A variation of collector 1, wherein the straight edge 41 of partition 40 slopes downward from the second rear wall 122 toward the first front wall 120. Specifically, refer to Figure 43 Edge 41 slopes downwards to present a greater extension at its intersection with the second rear wall 122 and a smaller extension at its intersection with the first front wall 120. In some cases, such as Figure 44 As shown, the straight edge 41 of the partition 40 has a lowered region 42 facing the interface 1240 and, in use, facing the nozzle 34 supported by the syringe 36 housed in the interface 1240, so as to allow the lateral portion of the nozzle 34 to overlap the partition, thereby maximizing the adaptability of the nozzle 34's position along the interface 1240 to accommodate different user nose shapes.

[0098] Based on the above description, it is easy to see that Collector 1 solves the typical shortcomings of the prior art in a simple and inexpensive way. In addition to allowing the definition of new operating procedures for sampling nasopharyngeal / olfactory nasal secretions of multiple groups of people to be analyzed in a completely safe and highly reliable manner, it also allows for the autonomous collection of nasal secretions mixed with the cleaning solution, eliminating the risk of third-party contamination and preventing errors.
