Description

Technical Field

[0001] This utility model relates to the field of reagent carriers, and in particular to a reagent carrier tray device. Background Technology

[0002] In the fields of biological detection and medical diagnostics, reagent carrier tray devices are key auxiliary equipment for scenarios involving multiple testing items. They need to be flexibly adaptable to different testing needs while balancing cost control and ease of use. Currently, most reagent carrier trays on the market adopt an integrated design with fixed item combinations. That is, the pre-set reagent carrier placement structure within the tray is only compatible with a few specific testing item combinations and cannot be flexibly adjusted according to actual testing needs. When there are fewer testing items or when testing items need to be changed, only the corresponding fixed combination of trays can be used, which easily leads to tray waste and increased testing costs. Utility Model Content

[0003] The main purpose of this invention is to overcome the shortcomings of existing trays that cannot meet the needs of multiple testing combinations and have poor versatility. This invention proposes a reagent carrier tray device to improve the practicality and applicability of the reagent carrier tray device in biological testing and medical diagnostic scenarios.

[0004] The present invention adopts the following technical solution:

[0005] A reagent carrier tray device includes a housing. On one side of the housing in the axial direction, there are a plurality of slots circumferentially distributed around the middle of the housing, and detection channels are provided in the slots. On the other side of the housing in the axial direction, there are a plurality of windows corresponding one-to-one with the plurality of detection channels, and clamping members are provided around the windows on the side opposite to the slots.

[0006] The housing has a plurality of ribs arranged circumferentially around the middle of the housing on one side of the axial direction. Each rib group has at least one first rib and at least one second rib to form the slot for accommodating the reagent carrier. The first rib extends obliquely along the radial direction of the housing, and at least one second rib extends obliquely along the circumference of the housing and is located at the end of the corresponding first rib along the radial direction of the housing.

[0007] The first rib has an inwardly recessed relief groove on the side facing the reagent carrier. The relief groove is located between the two ends of the first rib along the radial direction of the shell and corresponds to the reaction zone of the reagent carrier.

[0008] A third rib is provided around the side of the window opposite to the slot, and the third rib extends along the circumference of the window to form the clamping member; or at least one third rib is provided on the outer periphery of the side of the window opposite to the slot, and the at least one third rib is distributed along the circumference of the window to form the clamping member.

[0009] The housing is divided into a first housing and a second housing connected together; the first housing is provided with a plurality of slots; the second housing is provided with a plurality of windows.

[0010] The housing is further provided with a plurality of first fixing units distributed circumferentially around the middle of the housing and close to the middle of the housing to fix the first housing and the second housing, and a plurality of second fixing units distributed circumferentially around the middle of the housing and close to the radial outer periphery of the housing to fix the first housing and the second housing.

[0011] The first fixing unit and / or the second fixing unit adopt a snap-fit ​​structure, which includes a plurality of protrusions spaced circumferentially around the middle of the housing and a plurality of grooves spaced circumferentially around the middle of the housing; one of the protrusions and grooves is located in the first housing, and the other of the protrusions and grooves is located in the second housing, and the fixing is achieved by the protrusions snapping into the corresponding grooves.

[0012] The first fixing unit and / or the second fixing unit adopt a fastener locking structure. The first shell and the second shell are respectively provided with a plurality of fixing holes circumferentially distributed around the middle of the shell. The first shell and the second shell are also provided with a plurality of fasteners, which are fixed by passing through the fixing holes on the first shell and the second shell.

[0013] The housing has an axially penetrating mounting hole in the middle, and the inner wall of the mounting hole is also provided with at least one recess extending radially; and / or the housing has an axially penetrating positioning hole near the mounting hole.

[0014] The housing has an axially penetrating positioning hole near the mounting hole.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] 1. In this utility model, the slots distributed circumferentially around the center of the housing allow for flexible installation of suitable reagent carriers according to the number and type of testing items, without the need to replace the entire tray for different combinations of items. The radial positioning of the slots and the axial clamping of the clamping components form a double fixing structure, which ensures that the reagent carrier does not shift radially or loosen axially during the testing process, thus guaranteeing testing accuracy. The overall structure enables flexible adaptation of testing items, reduces tray waste, lowers testing costs, and also takes into account ease of use.

[0017] 2. In this utility model, the inclined ribs form a slot for the reagent carrier, which can stably limit the position of the reagent carrier; and the number of slots can be set as needed, which can flexibly combine reagent carriers of different items, making assembly convenient and efficient.

[0018] 3. In this utility model, an avoidance groove is provided on the first rib of the rib group, so that the first rib is spaced apart from the reagent carrier reaction zone, which can block the direct contact between the liquid and the rib, avoid the risk of siphoning due to capillary action, and ensure the stability of the liquid in the reaction zone.

[0019] 4. In this utility model, a split-type shell with an axially penetrating mounting hole in the middle is used as the core. A matching structure for placing and observing the reagent carrier is formed by the circumferential groove of the first shell and the detection channel, and the corresponding window of the second shell. Simultaneously, a first fixing unit near the middle of the shell and a second fixing unit near the outer periphery of the shell respectively achieve a fixed connection between the inner and outer rings of the shell. The use of a split-type shell with inner and outer double fixing units ensures the overall stability of the shell connection and avoids loosening or deformation of the shell due to insufficient strength in a single fixing area.

[0020] 5. In this utility model, the housing is provided with an axially penetrating positioning hole near the mounting hole, which can be used with the positioning column of the testing equipment to achieve positioning and installation; the recessed part of the mounting hole can also help the operator quickly find the correct pick-up and put-down angle, reducing the difficulty of operation.

[0021] 6. This utility model is suitable for the combined detection of a large number of reagent carriers for different items: operators can quickly load the reagent carriers corresponding to different items into the shell one by one according to the batch detection needs of multiple items, without repeatedly disassembling and assembling the overall structure, which is highly adaptable to the scenario of centralized detection of multiple items.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0036] The present invention will be further described below through specific embodiments.

[0037] See Figures 1 to 6 A reagent carrier tray device includes a housing 10 with an axially penetrating mounting hole 11 for detachably mounting the tray device onto a detection device. The mounting hole 11 is located in the middle of the housing 10. The housing 10 is a hollow structure with an internal cavity. On one axial side of the housing 10, there are several slots 12 circumferentially distributed around the middle of the housing 10. Each slot 12 contains a detection channel 13. The slots 12 are used for radial positioning of the reagent carrier 30, fixing the reagent carrier 30 on the radial plane of the housing 10. The detection channel 13 can be an axially penetrating through hole or a non-penetrating groove. On the other axial side of the housing 10, there are several windows 14 corresponding one-to-one with the detection channels 13. The windows 14 and the detection channels 13 are located on different sides of the reagent carrier 30. Around the windows 14 opposite to the slots 12, there are clamping members 10c. The clamping members 10c apply axial pressure to the reagent carrier 30, cooperating with the slots 12 to fix the reagent carrier 30 axially in the housing 10. The axial direction of housing 10 refers to the direction perpendicular to the radial plane of housing 10.

[0038] In this embodiment, the reagent carrier 30 is a carrier for holding the test reagents, and can be a reagent strip, reagent card, or reagent sheet, etc. The circumferentially distributed slots 12 around the center of the housing 10 allow for flexible adjustment of the number of reagent carriers 30 installed according to the number of test items, eliminating the need to replace the entire tray for different test combinations, improving the device's versatility, reducing tray waste and testing costs. The radial positioning of the slots 12 and the axial clamping of the clamping member 10c form a double fixing structure, ensuring that the reagent carrier 30 does not experience radial displacement or axial loosening during testing, thus guaranteeing testing accuracy. The detection channel 13 provides a universal interface for accessing the reagent carrier 30 from the housing 10. Regardless of whether optical, electrochemical, or other types of detection methods are used, it ensures the application of the detection stimulus and the stable transmission of the response signal, effectively improving the device's versatility and signal transmission reliability.

[0039] The housing 10 has a plurality of ribs 18 arranged circumferentially around the middle of the housing 10 on one axial side. Each rib 18 has at least one first rib 18a and at least one second rib 18b to form a slot 12 for accommodating the reagent carrier 30. The first rib 18a extends radially at an inclination, and the at least one second rib 18b extends circumferentially at an inclination and is located at the end of the corresponding first rib 18a on the radial side of the housing. The resulting slot 12 is also inclined relative to the radial side of the housing 10. The shape of the slot 12 is adapted to the shape of the reagent carrier 30, for example, it is rectangular.

[0040] It should be noted that the specific number of the first rib 18a and the second rib 18b can be flexibly set according to actual needs. For example, to simplify the structure and adapt to conventional reagent carriers 30, in the rib group 18 corresponding to each slot 12, the first rib 18a and the second rib 18b can each be set to one. By cooperating with a single radially inclined first rib 18a and a single circumferentially inclined second rib 18b, the basic positioning of the reagent carrier 30 can be achieved. Alternatively, for reagent carriers 30 requiring higher positioning stability, the rib group 18 corresponding to each slot 12 can be set with two first ribs 18a and two second ribs 18b. The two first ribs 18a are spaced apart along the circumference of the shell 10, and the two second ribs 18b are spaced apart along the radial direction of the shell 10. Through the synergistic positioning of multiple ribs, the fixing effect of the slot 12 on the reagent carrier 30 is further improved, and the reagent carrier 30 is prevented from shifting during the detection process.

[0041] Further, see Figure 8The first rib 18a has a recessed relief groove 18c on the side facing the reagent carrier 30. The relief groove 18c is located between the two ends of the first rib 18a along the radial direction of the shell 10 and corresponds to the reaction area 31 of the reagent carrier 30. That is, there is a gap between the relief groove 18c and the reaction area 31 of the reagent carrier 30, which blocks the direct contact between the liquid in the reaction area 31 of the reagent carrier and the first rib 18a. At the same time, the preset gap can prevent the liquid from spreading to the surface of the rib due to capillary action and avoid the risk of siphoning. Figure 8 In each slot 12, the two first protruding ribs 18a in each slot are respectively provided with clearance grooves 18c on opposite sides.

[0042] In this embodiment, a third rib is provided around the side of the window 14 opposite to the slot 12. The third rib extends circumferentially along the window 14 to form a clamping member 10c. The shape of the clamping member 10c is adapted to the contour of the window 14, and it is a protruding structure protruding from the sidewall of the window 14 but does not obstruct the window 14, so as not to affect the detection light or probe operation. In practical applications, at least one third rib can also be provided on the outer periphery of the side of the window 14 opposite to the slot 12, and each third rib is distributed circumferentially along the window 14 to form a clamping member 10c.

[0043] The housing 10 is divided into a first housing 10a and a second housing 10b, which are connected by mounting holes 11. The first housing 10a has a plurality of slots 12 distributed around the middle of the housing 10, that is, around the mounting holes 11. The second housing 10b has a plurality of windows 14 corresponding one-to-one with a plurality of detection channels 13. The housing 10 is also provided with a plurality of first fixing units 15 distributed around the mounting holes 11 and close to the mounting holes 11 to fix the first housing 10a and the second housing 10b, and a plurality of second fixing units 16 distributed around the mounting holes 11 and close to the radial outer periphery of the housing 10 to fix the first housing 10a and the second housing 10b. The inner ring of the housing 10 is fixed by the first fixing units 15, and the outer ring of the housing 10 is fixed by the second fixing units 16.

[0044] In this embodiment, a split-type housing 10 with an axially penetrating mounting hole 11 in the center serves as the core. A mating structure for placing and observing the reagent carrier 30 is formed by the circumferential groove 12 of the first housing 10a and the detection channel 13, and the corresponding window 14 of the second housing 10b. Simultaneously, a first fixing unit 15 near the mounting hole 11 and a second fixing unit 16 near the outer periphery of the housing 10 respectively achieve a fixed connection between the inner and outer rings of the housing 10. The use of a split-type housing 10 with inner and outer dual fixing units ensures the overall stability of the housing 10 connection and prevents loosening or deformation of the housing 10 due to insufficient strength in a single fixing area.

[0045] Multiple reinforcing ribs 17 may also be provided on the first shell 10a and the second shell 10b of the shell 10. The reinforcing ribs 17 may be located at appropriate positions on the shell 10 to further disperse the external forces that the shell 10 is subjected to during installation and use, effectively preventing the shell 10 from deforming or breaking due to uneven stress, thereby significantly increasing the overall strength of the shell 10.

[0046] Furthermore, the first fixing unit 15 adopts a snap-fit ​​structure, which includes a plurality of protrusions 19 spaced circumferentially around the mounting hole 11 and a plurality of grooves 20 spaced circumferentially around the mounting hole 11; one of the plurality of protrusions 19 and the plurality of grooves 20 is located in the first shell 10a, and the other of the plurality of protrusions 19 and the plurality of grooves 20 is located in the second shell 10b. Fixing is achieved by the protrusions 19 snapping into the corresponding grooves 20 with an interference fit. The protrusions 19 are raised strips, and the grooves 20 are grooves or snap holes formed by two raised strips. Snap-fit ​​is achieved by the raised strips being inserted into the corresponding grooves or snap holes; or the protrusions 19 are raised pillars, and the grooves 20 are grooves set on a similar pillar structure. Snap-fit ​​is achieved by the raised pillars snapping into countersunk holes. The shape of the protrusions can be rectangular, circular, or arc-shaped, etc., and the shape of the grooves is adapted to the shape of the protrusions. In the figure, the first shell 10a is provided with both convex strips and convex pillars 19, while the second shell 10b is provided with corresponding grooves 20 that are adapted to the convex strips and grooves 20 that are adapted to the convex pillars. Through the combination of multiple types of snap-fit ​​structures, the stability and adaptability of the inner ring connection between the first shell 10a and the second shell 10b are further improved.

[0047] Similarly, the second fixing unit 16 can also adopt a snap-fit ​​structure, and this second fixing unit 16 is located near the outer periphery of the housing 10. The protrusion 19 is a ridge, and the groove 20 is a groove formed by two ridges. The snap-fit ​​is achieved by inserting the ridge into the corresponding groove and making an interference fit; or the protrusion 19 is a post, and the groove 20 is a groove set on a similar post structure. The snap-fit ​​is achieved by the post engaging the countersunk hole. In the figure, the groove 20 formed by two ridges is provided on the first housing 10a, and the ridge is provided on the second housing 10b. Since the second fixing unit 16 is located on the outer ring, the number of its protrusions 19 is greater than that of the first fixing unit 15, and the number of its grooves 20 is also greater than that of the first fixing unit 15.

[0048] In practical applications, the first and second fixing units can also employ a fastener locking structure. The first shell 10a and the second shell 10b each have corresponding fixing holes, which are circumferentially spaced around the mounting hole 11 in the center of the shell 10. The fixing holes on the first shell 10a and the second shell 10b correspond one-to-one in the axial direction. Simultaneously, the fixing unit also includes several suitable fasteners, which are inserted through the fixing holes on the first shell 10a and the second shell 10b for fixation. Fastener locking further enhances the connection strength of the fixing unit. The first fixing unit (near the mounting hole, used to fix the inner ring of the shell) and the second fixing unit (near the outer periphery of the shell, used to fix the outer side of the shell) can also be fixedly connected by welding.

[0049] Specifically, the first fixing unit 15 (near the mounting hole 11, used to fix the inner ring of the housing 10) and the second fixing unit 16 (near the outer periphery of the housing 10, used to fix the outer side of the housing 10) can also be fixedly connected by welding. Welding processes (such as ultrasonic welding, laser welding, etc.) are used in the corresponding connection areas of the mounting holes 11 of the first housing 10a and the second housing 10b to form a strong welded joint at the connection points of the inner rings of the two housings; similarly, the second fixing unit 16 can be fixed by welding in the corresponding connection areas of the outer periphery of the first housing 10a and the second housing 10b.

[0050] See Figure 11 The inner wall of the mounting hole 11 is also provided with at least one radially extending recess 21, which can engage with the corresponding protrusion 41 on the testing equipment. On the one hand, through the positioning effect of the recess 21 and the corresponding protrusion 41 on the equipment, the operator can more easily find the correct installation or disassembly angle when picking up and placing the tray device, reducing the difficulty of the operation. On the other hand, the small gap between the recess 21 and the corresponding protrusion 41 on the equipment can further improve the coaxiality and connection tightness of the tray device and the testing equipment after installation, avoiding radial shaking of the tray device during the testing process due to excessive gap, thereby ensuring the stability of the testing environment of the reagent carrier 30. The number of recesses 21 can be one, two, or even more; two are shown as an example in the figure.

[0051] In this embodiment, an axially penetrating positioning hole 22 is provided on the first shell 10a and the second shell 10b near the mounting hole 11. This hole is used to cooperate with the positioning post 42 corresponding to the tray device on the testing equipment. When the tray device is assembled onto the testing equipment, the positioning post 42 of the corresponding part on the equipment can be inserted into the positioning hole 22 to realize the positioning and installation of the tray device on the testing equipment.

[0052] In this embodiment, the housing 10 is designed for single use and can be made of HIPS or ABS. The number of slots 12 inside the housing 10 can be set according to requirements, such as 15-25, with 19 slots shown in the figure. In use, the first housing 10a and the second housing 10b are placed separately. The reagent carrier 30 of the corresponding specification is selected according to the requirements of the test item (the reagent carriers 30 of different items can be combined). The reagent carrier 30 is placed in the slot 12 of the first housing 10a. The first rib 18a (radially inclined) and the second rib 18b (circumferentially inclined) can form a stable limit for the reagent carrier 30, preventing axial or circumferential displacement during the subsequent housing assembly process. Next, the second housing 10b is aligned with the assembly position of the first housing 10a. The protrusions 19 of the first fixing unit 15 (inner ring buckle) and the grooves 20 of the second fixing unit 16 (outer ring buckle) are matched and fastened to complete the stable assembly of the first housing 10a and the second housing 10b.

[0053] Based on this, the detection process of the device in this embodiment specifically includes the following operations:

[0054] Multiple reagent carriers 30 are prepared for a preset project combination. Each reagent carrier 30 carries a reagent that matches the preset project combination. Each reagent carrier 30 is assembled into the corresponding slot 12 of the housing 10, and the reaction area 31 of each reagent carrier 30 is aligned with the corresponding window 14 and detection channel 13. The reagent carrier 30 is fastened by the clamping member 10c. When testing the sample to be tested, a detection stimulus is applied to the reaction area 31 of the reagent carrier 30 through the detection channel 13, and the response signal from the reaction area 31 is obtained through the detection channel 13 for processing to obtain a variety of detection data that match the preset project combination.

[0055] In this embodiment, the detection stimulus can be selected according to the detection principle and the requirements of the preset item combination, including but not limited to optical signals, thermal signals, electrical signals, chemical signals, magnetic signals, etc. Taking optical signals as the detection stimulus as an example, the detection device can emit light of a specific wavelength to the reaction area 31 of the reagent carrier 30 through the detection channel 13. After the reagent carried in the reaction area 31 reacts specifically with the sample to be detected, it will produce optical responses such as fluorescence, absorbance changes or scattered light. The optical response signals are received and processed through the detection channel 13 to provide a reliable basis for the analysis and processing of subsequent detection data.

[0056] This embodiment is suitable for combined detection of a large number of reagent carriers 30 for different items: operators can quickly load the reagent carriers 30 for different items into the housing 10 one by one according to the batch detection needs of multiple items, without having to repeatedly disassemble and reassemble the overall structure, which is highly adaptable to the scenario of centralized detection of multiple items.

[0057] The following examples, through different combinations of reagent strips and their adaptation to various detection items, illustrate the practical application of the detection methods of this device, fully demonstrating its core advantage of flexibly adapting to multiple detection item combinations:

[0058] 19 test strips compatible with 24 testing items

[0059] 24 items in total: 1. Nineteen reagent strips are selected, each carrying a corresponding test reagent for TP (total protein), ALB (albumin), ALT (alanine aminotransferase), ALKP (alkaline phosphatase), TBIL (total bilirubin), GGT (gamma-glutamyl transferase), CHOL (cholesterol), GLU (glucose), BUN (urea), CREA (creatinine), AMYL (amylase), LIPA (lipase), CA (calcium), PHOS (phosphorus), TRIG (triglycerides), AST (aspartate aminotransferase), CK (creatine kinase), NH3 (ammonia), and UA (uric acid). The 19 reagent strips are assembled one by one into the 19 slots of the tray shell and fixed by the clamping component 10c. The detection light is incident on the reaction area 31 of each reagent strip through the detection channel to directly obtain the detection results of the above 19 indicators.

[0060] Then, by using a fixed calculation formula, based on 19 direct test results, five indicators were derived: AST / ALT (AST / ALT ratio), CA*P (calcium-phosphorus product), GLOB (globulin), ALB / GLOB (albumin / globulin ratio), and BUN / CREA (urea / creatinine ratio). Finally, 24 tests were completed simultaneously.

[0061] Combining 24 items 2: 19 reagent strips are selected, each carrying the corresponding detection reagents for TP, ALB, ALT, ALKP, TBIL, GGT, CHOL, GLU, BUN, CREA, AMYL, PL (phospholipids), CA, PHOS, TRIG, AST, CK, NH3, and UA. Following the same assembly and detection process as described above, the results of the 19 indicators are directly obtained. Then, the 5 indicators AST / ALT, CA*P, GLOB, ALB / GLOB, and BUN / CREA are derived through fixed formulas, thus achieving the adaptation of another set of 24 detection items.

[0062] 15 test strips compatible with 18 testing items

[0063] The comprehensive 18-item test involves selecting 15 reagent strips, each carrying a corresponding test reagent for TP, ALB, ALT, ALKP, TBIL, GGT, CHOL, GLU, BUN, CREA, AMYL, LIPA, CA, PHOS, and TRIG. After assembly and fixation, the results of 15 indicators are directly obtained. Then, GLOB and ALB / GLOB are derived based on TP and ALB using fixed formulas, and BUN / CREA is derived based on BUN and CREA, ultimately completing the 18-item test.

[0064] The comprehensive 18-item 2: 15 reagent strips are selected, each carrying the corresponding test reagents for TP, ALB, ALT, ALKP, TBIL, GGT, CHOL, GLU, BUN, CREA, AMYL, PL, CA, PHOS, and TRIG. After obtaining the 15 results directly using the same procedure, the GLOB, ALB / GLOB, and BUN / CREA indicators are derived using fixed formulas to adapt to another set of 18 test requirements.

[0065] The comprehensive test involves 18 items: 15 reagent strips are selected, each carrying the corresponding test reagents for TP, ALB, ALT, ALKP, TBIL, GGT, CHOL, GLU, BUN, CREA, AMYL, PL, CA, PHOS, and CK; after assembly and testing, the GLOB, ALB / GLOB, and BUN / CREA indicators are derived directly from the results, enabling flexible replacement of the 18 test items.

[0066] 7 test strips compatible with 11 testing items

[0067] Preoperative 11 items 1: Seven reagent strips are selected, each carrying the corresponding test reagents for ALB, ALKP, ALT, BUN, CREA, GLU, and TP. After assembly and fixation, the results of the seven indicators are directly obtained. Then, GLOB and ALB / GLOB are derived based on TP and ALB, and BUN / CREA is derived based on BUN and CREA, using fixed formulas. Combined with the directly detected PHOS indicators, the 11 preoperative tests are finally completed.

[0068] Preoperative 11 items 2: Select 7 reagent strips, each carrying the corresponding test reagents for ALB, ALKP, ALT, BUN, CREA, GLU, and TP; after obtaining the results of the 7 items directly according to the same procedure, GLOB, ALB / GLOB, and BUN / CREA are derived through fixed formulas, and combined with the directly detected CK index, to adapt another set of preoperative 11 items tests.

[0069] Preoperative 11 items 3: Seven reagent strips are selected, each carrying the corresponding test reagents for ALB, ALKP, ALT, UREA (urea, synonym of BUN), CREA, GLU, and TP. After assembly and testing, GLOB, ALB / GLOB, and BUN / CREA are derived directly from the results, and combined with the directly detected AST index, to complete the flexible adaptation of the 11 preoperative tests.

[0070] The above cases demonstrate that when using the device of this utility model for testing, based on the circumferential distribution layout of the slots of the same tray device, the corresponding number and type of reagent strips can be flexibly selected according to the quantity requirements of the preset test item combination. The tray is precisely assembled through the slot positioning and clamping parts. There is no need to replace the entire tray. By simply adjusting the number and type of the assembled reagent strips, combinations of different test requirements such as 24 items, 18 items, and 11 items can be adapted.

[0071] In this utility model, the terms "first," "second," and "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing this utility model, and does not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0072] Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
