Fixed installation assembly for bronchial blocker and blocking pipe

Abstract

This invention relates to a bronchial occluder and a fixing and installation assembly for the occluder tube. The fixing and installation assembly includes an installation tube, a first elastic seal, and a clamping member. When the occluder tube needs to be fixed in place, the clamping member is adjusted to the clamping position, clamping the first elastic seal, which reduces the diameter of the second orifice and makes it fit tightly against the occluder tube. This ensures a tight seal by interfering with the first orifice and the occluder tube, while also further improving the seal by ensuring a tight fit between the second orifice and the occluder tube, resulting in good installation stability. When the occluder tube needs to be removed, the clamping member is adjusted to the loosening position, releasing the first elastic seal. The first elastic seal then returns to its original position, creating a clearance fit between the second orifice and the occluder tube. This allows the occluder tube to be easily removed, and the interference fit between the first orifice and the occluder tube provides a seal, preventing air leakage during breathing.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a bronchial occluder and a fixing and installation assembly for the occluder tube. Background Technology

[0002] Bronchial occluders are widely used in thoracic surgery for airway management, including single-lung ventilation, separate ventilation of both lungs, and occlusion. Clinically, bronchial occluders have value in single-lung ventilation during open-chest surgery, providing good lung collapse, selectively occluding the entire lung and lobes, and improving intraoperative hypoxemia.

[0003] A bronchial occlusion device comprises an occlusion fitting, an endotracheal tube, and a breathing circuit, among other components. During use, the occlusion fitting must be used in conjunction with these components, ensuring a tight seal and secure fixation. However, due to the small diameter of the occlusion fitting, during use, either a seal cannot be achieved without securing it, or it may be secured but becomes unusable due to easy deformation from compression. Furthermore, since the occlusion fitting is inserted into the endotracheal tube, it interferes with the use of the breathing circuit and poses a safety hazard. It must be removed from the endotracheal tube promptly. However, during removal, a portion of the endotracheal tube may be opened, causing air leakage and affecting the patient's respiratory treatment outcomes. Summary of the Invention

[0004] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a fixed installation assembly for a bronchial occluder and occluder fitting. This assembly can ensure the stability of the occluder fitting installation, facilitate disassembly and assembly, and provide a good sealing effect, thereby minimizing breathing leakage during the removal of the occluder fitting.

[0005] The technical solution is as follows: a fixing and installation assembly for a sealing pipe fitting, the fixing and installation assembly for the sealing pipe fitting comprising:

[0006] The mounting tube has a support portion surrounding its inner wall;

[0007] A first elastic seal is located inside the mounting tube and abuts against the support portion. The first elastic seal has a first through hole for inserting a sealing tube. The first through hole includes a first hole segment and a second hole segment that are sequentially connected along the axial direction. The distance between the first hole segment and the support portion is less than the distance between the second hole segment and the support portion. The first hole segment is interference-fitted with the sealing tube, and the diameter of the first hole segment is smaller than the diameter of the second hole segment.

[0008] A clamping component is adjustablely connected to the mounting tube and abuts against the first elastic seal. The clamping component has a clamping position and a loosening position. When the clamping component is in the clamping position, it clamps the first elastic seal, reducing the diameter of the second hole section and tightly fitting it to the sealing tube. When the clamping component is in the loosening position, it releases the first elastic seal, allowing the second hole section to have a clearance fit with the sealing tube.

[0009] In one embodiment, the clamping member includes a clamping portion circumferentially disposed around the first elastic seal, the wall surface of the clamping portion abutting against the first elastic seal including a first wall surface, the first wall surface being disposed at an acute angle to the axial direction of the mounting tube; and / or, the wall surface of the first elastic seal abutting against the clamping portion including a second wall surface, the second wall surface being disposed at an acute angle to the axial direction of the mounting tube; and / or, the fixing and mounting assembly of the sealing tube further includes a sealing gasket; the sealing gasket is disposed between the support portion and the first elastic seal; the fixing and mounting assembly of the sealing tube further includes a first sealing member, the first sealing member being used to seal one end of the mounting tube.

[0010] In one embodiment, the first wall surface is a conical surface, the second wall surface is a conical surface; and / or, the clamping member further includes a mounting cap that is positionably connected to the mounting tube, the clamping part being connected to the mounting cap, and the mounting cap having a second through hole for inserting the sealing tube.

[0011] In one embodiment, the mounting cover includes a top plate and a surrounding plate connected to the top plate; the clamping part is connected to the top plate; the inner wall of the surrounding plate is provided with a first thread, and the outer wall of the mounting tube is provided with a second thread adapted to the first thread; or, the outer wall of the surrounding plate is provided with a first thread, and the inner wall of the mounting tube is provided with a second thread adapted to the first thread.

[0012] In one embodiment, the first sealing member includes a first connector, a first sealing head connected to one end of the first connector, and a first mounting part connected to the other end of the first connector. The first mounting part is connected to the mounting tube, and the first sealing head is used to seal one end of the mounting tube.

[0013] A bronchial occluder includes a fixing and installation assembly for the occluder fitting, and further includes a pipe connector and the occluder fitting. The pipe connector is connected to the installation pipe, and the occluder fitting is sequentially inserted through the installation pipe and the pipe connector. The bronchial occluder also includes a second elastic seal. The second elastic seal is connected to the installation pipe and / or the pipe connector, and has an opening in its middle portion, through which the occluder fitting passes.

[0014] In one embodiment, the second elastic seal includes a second mounting portion and at least two support portions connected to the second mounting portion; the second mounting portion is connected to the mounting pipe and / or the pipe joint, the support portion is provided with an inclined surface at an angle to its central axis, and the middle portion of the second elastic seal protrudes in a direction away from the mounting pipe.

[0015] In one embodiment, the second resilient seal further includes at least one reinforcing portion connected to the support portion; the reinforcing portion includes one or more combinations of an arc-shaped plate, an S-shaped plate, a Z-shaped plate, and a straight plate.

[0016] In one embodiment, the mounting tube and the pipe joint are interlocked, and the second elastic seal is engaged between the mounting tube and the pipe joint.

[0017] In one embodiment, the tubing connector includes a main pipe and a first branch pipe and a second branch pipe connected to the main pipe; one end of the main pipe is connected to the mounting pipe, and the other end of the main pipe is used to insert into the main trachea; the first branch pipe is used to connect to a suction device, and the second branch pipe is used to connect to a breathing tubing.

[0018] The aforementioned bronchial occluder and occluder fitting fixing assembly, when the occluder fitting needs to be fixed in place, adjusts the clamping member to the clamping position. The clamping member presses against the first elastic seal, reducing the diameter of the second orifice section and making it tightly fitted to the occluder fitting. This ensures a tight seal by interfering with the first orifice section and the occluder fitting, while also further improving the seal by ensuring a tight fit between the second orifice section and the occluder fitting. The assembly also provides good stability. When the occluder fitting needs to be removed, the clamping member is adjusted to the loosening position. The clamping member releases the first elastic seal, which then returns to its original position, creating a clearance fit between the second orifice section and the occluder fitting. This allows the occluder fitting to be easily removed, and the interference fit between the first orifice section and the occluder fitting provides a good seal, preventing air leakage during breathing.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] See Figures 1 to 4 , Figure 1 A schematic diagram of the structure of a bronchial occluder according to an embodiment of this application is shown. Figure 2 It shows Figure 1 A cross-sectional view of the structure shown. Figure 3This illustration shows a structural diagram of the process of removing the sealing tube 70 according to an embodiment of this application. Figure 4 It shows Figure 3 Enlarged structural diagram at point A. An embodiment of this application provides a fixing and mounting assembly for a sealing pipe fitting, comprising: an mounting pipe 10, a first elastic seal 20, and a clamping member 30. A support portion 11 is provided around the inner wall of the mounting pipe 10. The first elastic seal 20 is located inside the mounting pipe 10 and abuts against the support portion 11. The first elastic seal 20 has a first through hole 21 for inserting the sealing pipe fitting 70. The first through hole 21 includes a first hole segment 211 and a second hole segment 212 sequentially connected along the axial direction. The distance between the first hole segment 211 and the support portion 11 is less than the distance between the second hole segment 212 and the support portion 11. The first hole segment 211 is interference-fitted with the sealing pipe fitting 70, and the diameter of the first hole segment 211 is smaller than the diameter of the second hole segment 212. The clamping member 30 is adjustablely connected to the mounting pipe 10 and abuts against the first elastic seal 20. The clamping member 30 has a clamping position and a loosening position. Please see Figure 2 When the clamping member 30 is in the clamping position, it clamps the first elastic sealing member 20, causing the diameter of the second hole section 212 to decrease and fit tightly against the sealing pipe fitting 70; please refer to Figure 4 When the clamping member 30 is in the loosened position, the clamping member 30 loosens the first elastic sealing member 20, so that the second hole section 212 and the sealing pipe 70 are in clearance fit.

[0041] When the sealing pipe fitting 70 needs to be fixed after being moved into place, the clamping member 30 is adjusted to the clamping position. The clamping member 30 clamps the first elastic sealing member 20, which reduces the diameter of the second hole section 212 and makes it fit tightly against the sealing pipe fitting 70. In this way, on the one hand, the first hole section 211 and the sealing pipe fitting 70 are interference-fitted, which ensures the sealing performance; on the other hand, the second hole section 212 also fits tightly against the sealing pipe fitting 70, which further improves the sealing performance and also ensures good installation stability. When the plugging fitting 70 needs to be removed, the clamping member 30 is adjusted to the loosened position, the clamping member 30 loosens the first elastic seal 20, and the first elastic seal 20 returns to its original state so that the second hole section 212 is clearance-fitted with the plugging fitting 70. In this way, the second hole section 212 of the first elastic seal 20 loosens the plugging fitting 70, and the plugging fitting 70 can be easily removed. Because the first hole section 211 is interference-fitted with the plugging fitting 70, it plays a good sealing role and prevents air leakage.

[0042] In one embodiment, the first elastic seal 20 may be, but is not limited to, elastic materials such as silicone, elastic resin, and polyethylene plastic, and can be flexibly selected according to actual needs. In this embodiment, the first elastic seal 20 is specifically made of, for example, medical-grade silicone.

[0043] Please see Figure 4 , Figures 7 to 10 , Figure 7 This paper shows a schematic diagram of the clamping member 30 according to an embodiment of the present application. Figure 8 It shows Figure 7 The sectional view of the structure shown. Figure 9 This paper shows a schematic diagram of the structure of the first elastic seal 20 according to an embodiment of the present application. Figure 10 It shows Figure 9 The diagram shows a cross-sectional view of the structure. In one embodiment, the clamping member 30 includes a clamping portion 31 circumferentially disposed around the first elastic seal 20. The wall surface of the clamping portion 31, which abuts against the first elastic seal 20, includes a first wall surface 311, which is set at an acute angle to the axial direction of the mounting tube 10. And / or, the wall surface of the first elastic seal 20, which abuts against the clamping portion 31, includes a second wall surface 22. The second wall surface 22 is set at an acute angle to the axial direction of the mounting tube 10. Thus, when the clamping member 30 moves along the axial direction of the mounting tube 10 and clamps the first elastic seal 20, the diameter of the second hole section 212 can be reduced and tightly fitted to the sealing tube 70 by squeezing the first elastic seal 20.

[0044] Specifically, when the first wall surface 311 is set at an acute angle to the axis of the mounting tube 10, that is, when the first wall surface 311 is an inclined surface, the second wall surface 22 can also be set at an acute angle to the axis of the mounting tube 10, that is, the second wall surface 22 can be set accordingly as an inclined surface. Of course, the second wall surface 22 can also be parallel to the axis of the mounting tube 10. When the first wall surface 311 moves along the axis and abuts against the second wall surface 22, it can achieve the pressing of the first elastic seal 20. Conversely, when the second wall surface 22 is set at an acute angle to the axis of the mounting tube 10, that is, when the second wall surface 22 is set accordingly as an inclined surface, the first wall surface 311 can also be set at an acute angle to the axis of the mounting tube 10, that is, when the first wall surface 311 moves along the axis and abuts against the second wall surface 22, it can achieve the pressing of the first elastic seal 20.

[0045] In this embodiment, the first wall surface 311 is set as an inclined surface, the second wall surface 22 is set as an inclined surface, and the deviation of the included angle formed with the axis of the mounting tube 10 is controlled within 10° for example. In this way, the clamping member 30 has good stability during the process of clamping the first elastic sealing member 20.

[0046] Please see Figure 4 , Figures 7 to 10In one embodiment, the first wall surface 311 is a conical surface, and the second wall surface 22 is a conical surface. Thus, during the process of the clamping member 30 clamping the first elastic sealing member 20, the first elastic sealing member 20 experiences uniform force in all parts of the circumferential direction, achieving a tight fit with the sealing pipe 70 and a good sealing effect.

[0047] In one embodiment, the clamping member 30 is connected to the mounting tube 10 by means of threaded connection, snap-fit, adhesive, or fasteners such as pins, rivets, and screws.

[0048] Please see Figure 4 , Figures 7 to 10 In one embodiment, the clamping member 30 further includes a mounting cap 32 that is positionally adjustable to the mounting tube 10. The clamping part 31 is connected to the mounting cap 32, and the mounting cap 32 is provided with a second through hole 321 for inserting the sealing tube 70.

[0049] Please see Figure 4 , Figures 7 to 10 In one embodiment, the mounting cover 32 includes a top plate 322 and a surrounding plate 323 connected to the top plate 322. A clamping part 31 is connected to the top plate 322. A first thread is provided on the inner wall of the surrounding plate 323, and a second thread adapted to the first thread is provided on the outer wall of the mounting tube 10. Alternatively, the first thread is provided on the outer wall of the surrounding plate 323, and a second thread adapted to the first thread is provided on the inner wall of the mounting tube 10. Thus, the mounting cover 32 can be adjusted to a clamped or released position by rotation.

[0050] Please see Figure 4 In one embodiment, the fixing assembly for the sealing pipe fitting further includes a sealing gasket 40. The sealing gasket 40 is disposed between the support portion 11 and the first elastic seal 20. Thus, the sealing gasket 40 enhances the sealing performance at the contact point between the support portion 11 and the first elastic seal 20.

[0051] Please see Figure 4 , Figure 5 and Figure 11 , Figure 5 This paper shows a schematic diagram of the structure of one end of the first sealing member 50 sealing the mounting tube 10 according to an embodiment of this application. Figure 11 A schematic diagram of the first sealing member 50 according to an embodiment of this application is shown. In one embodiment, the fixing and mounting assembly of the sealing tube further includes the first sealing member 50. The first sealing member 50 is used to seal one end of the mounting tube 10. Thus, when the first elastic seal 20, the clamping member 30, and the sealing tube 70 are all removed from the inside of the mounting tube 10, the first sealing member 50 seals one end of the mounting tube 10, thereby preventing air leakage.

[0052] Please see Figure 4 , Figure 5 and Figure 11 In one embodiment, the first sealing member 50 includes a first connector 51, a first sealing head 52 connected to one end of the first connector 51, and a first mounting portion 53 connected to the other end of the first connector 51. The first mounting portion 53 is connected to the mounting tube 10, and the first sealing head 52 is used to seal one end of the mounting tube 10.

[0053] Optionally, the first connecting member 51 may include, but is not limited to, a flexible member, an elastic member, a shaped member, etc., specifically such as an elastic band, a flexible band, a shaped band, an elastic rod, a flexible rope, a chain rope, etc.

[0054] Optionally, the first sealing head 52 may include, but is not limited to, a resilient first sealing head 52. Furthermore, a flange is provided around the outer wall of the first sealing head 52.

[0055] Optionally, the first mounting part 53 may be mounted on the mounting tube 10 by means of, but not limited to, sleeved, snapped, or adhesive.

[0056] Please see Figures 1 to 4 In one embodiment, a bronchial occluder includes a fixed installation assembly for the occluder fitting of any of the above embodiments, and further includes a pipe joint 60 and an occluder fitting 70. The pipe joint 60 is connected to the installation pipe 10, and the occluder fitting 70 is sequentially inserted into the installation pipe 10 and the pipe joint 60.

[0057] The aforementioned bronchial occluder, when the occluder fitting 70 needs to be fixed in place, adjusts the clamping member 30 to the clamping position. The clamping member 30 presses against the first elastic sealing member 20, reducing the diameter of the second orifice 212 and making it tightly fitted with the occluder fitting 70. This ensures a tight seal by interfering with the first orifice 211 and the occluder fitting 70, while also further improving the seal by ensuring a tight fit between the second orifice 212 and the occluder fitting 70. Simultaneously, it provides good installation stability. When occluding... When the pipe fitting 70 needs to be removed, the clamping member 30 is adjusted to the loosened position, the clamping member 30 loosens the first elastic sealing member 20, and the first elastic sealing member 20 returns to its original state so that the second hole section 212 is clearance-fitted with the sealing pipe fitting 70. In this way, the second hole section 212 of the first elastic sealing member 20 loosens the sealing pipe fitting 70, and the sealing pipe fitting 70 can be easily removed. Since the first hole section 211 is interference-fitted with the sealing pipe fitting 70, it plays a good sealing role and prevents air leakage.

[0058] It should be noted that the "installation pipe 10" can be a part of the "pipe joint 60", that is, the "installation pipe 10" and the "other parts of the pipe joint 60" can be integrally formed; or it can be a separate component that can be separated from the "other parts of the pipe joint 60", that is, the "installation pipe 10" can be manufactured independently and then combined with the "other parts of the pipe joint 60" to form a whole.

[0059] In one embodiment, the bronchial occluder further includes a second elastic seal 80. The second elastic seal 80 is connected to the installation pipe 10 and / or the pipe connector 60, and has an opening 801 at its central portion. The occlusion fitting 70 passes through the opening 801, and the wall of the opening 801 is tightly fitted against the outer wall of the occlusion fitting 70 to achieve a seal. Thus, when the occlusion fitting 70 is sequentially inserted into the first elastic seal 20 and the second elastic seal 80, a double seal is formed, resulting in a better sealing effect.

[0060] Please see Figure 3 and Figure 4 In one specific embodiment, the mounting tube 10 and the pipe connector 60 are separate designs and are connected to each other, for example, by a snap-fit ​​method. Furthermore, a second resilient seal 80 is snapped between the mounting tube 10 and the pipe connector 60. This facilitates the installation and removal of the second resilient seal 80.

[0061] In one embodiment, the opening 801 includes, but is not limited to, regular shapes such as strip openings, circular openings, square openings, triangular openings, and irregular shapes, which can be flexibly adjusted and set according to actual needs.

[0062] Please see Figures 12 to 17 , Figures 12 to 14 A schematic diagram of the structure of a second resilient seal 80 according to one embodiment is shown; Figures 15 to 17 A schematic diagram of the structure of a second resilient seal 80 according to another embodiment is shown. The main difference between the two embodiments of the second resilient seal 80 lies in the shape of the reinforcing member. In one embodiment, the second resilient seal 80 includes a second mounting portion 81 and at least two support portions 82 connected to the second mounting portion 81. The second mounting portion 81 is connected to the mounting pipe 10 and / or the pipe joint 60, and the support portions 82 are provided with a connection to the central axis of the second resilient seal 80 (e.g., ...). Figure 14The second elastic seal 80 has a beveled surface (shown as Z in the diagram) with an included angle, and the middle portion of the second elastic seal 80 protrudes in a direction away from the mounting pipe 10. Thus, during the assembly of the sealing pipe fitting 70, the beveled surface acts as a guide, allowing the sealing pipe fitting 70 to move along the beveled surface to and through the opening 801, thereby facilitating the assembly operation of the sealing pipe fitting 70. Furthermore, because the middle portion of the second elastic seal 80 protrudes in a direction away from the mounting pipe 10, it functions as a one-way valve, effectively preventing air leakage.

[0063] In one embodiment, the inclined plane includes, but is not limited to, regular shapes such as planes, curved surfaces, Z-shaped surfaces, and irregular shapes, which can be flexibly adjusted and set according to actual needs.

[0064] Please see Figures 12 to 17 In one specific embodiment, there are two support portions 82, which are plate-shaped. One end of each support portion 82 is connected to the second mounting portion 81, and the other ends of the two support portions 82 are connected to each other, forming an opening 801. Furthermore, the second elastic seal 80 also includes two sealing portions 83 connected to the second mounting portion 81, located on opposite sides of the support portion 82. The side of one support portion 82 is connected to the side of the other support portion 82 through a corresponding sealing portion 83.

[0065] In one embodiment, the second elastic seal 80 further includes at least one reinforcing portion 84 connected to the support portion 82. The reinforcing portion 84 includes one or more combinations of an arc-shaped plate, an S-shaped plate, a Z-shaped plate, and a straight plate. Thus, when the sealing tube 70 is inserted into the opening 801 of the second elastic seal 80, the reinforcing portions 84 distributed around it generate a certain elastic force, thereby increasing the force on the sealing tube 70 at the opening 801 of the second elastic seal 80, resulting in better sealing performance. When the sealing tube 70 is pulled out of the second elastic seal 80, under the action of the reinforcing portion 84, the closing speed of the opening 801 of the second elastic seal 80 is accelerated, and air leakage is less likely.

[0066] In one embodiment, a step is provided around the inner wall of the mounting tube 10, and the second mounting part 81 is located on the step and abuts against the pipe joint 60. During the process of mounting the tube 10 being fitted onto the pipe joint 60, it is fixed to the pipe joint 60 by a snap-fit ​​method, and at the same time, it can also clamp and fix the second elastic seal 80.

[0067] Please see Figure 1 and Figure 3In one embodiment, the tubing connector 60 includes a main pipe 61 and a first branch pipe 62 and a second branch pipe 63 connected to the main pipe 61. One end of the main pipe 61 is connected to the mounting pipe 10, and the other end of the main pipe 61 is used to insert into the main trachea. The first branch pipe 62 is used to connect to a suction device, and the second branch pipe 63 is used to connect to a breathing circuit.

[0068] Specifically, the first branch pipe 62 is also provided with an openable second sealing member 64. The second sealing member 64 is used to seal the end of the first branch pipe 62. Optionally, the second sealing member 64 includes a second connector 641, a second sealing head 642 connected to one end of the second connector 641, and a third mounting part connected to the other end of the second connector 641. The third mounting part is connected to the first branch pipe 62, and the second sealing head 642 is used to seal the end of the first branch pipe 62.

[0069] Please see Figure 1 and Figure 2 In one embodiment, the occlusion fitting 70 is provided with an inflatable first balloon 71. Thus, during surgery, after the occlusion fitting 70 is assembled, the first balloon 71 inflates to increase its volume, thereby occluding the bronchus. When it is necessary to remove the occlusion fitting 70, the gas inside the first balloon 71 is released.

[0070] Please see Figure 6 , Figure 6 A schematic diagram of an auxiliary tube 90 provided on the tubing connector 60 is shown. In one embodiment, the bronchial occluder further includes the auxiliary tube 90. The auxiliary tube 90 is connected to the tubing connector 60, specifically to the main tube 61. Furthermore, the auxiliary tube 90 is equipped with an inflatable second balloon 91. In actual surgical procedures, it is often used for patients who cannot breathe independently (such as those in a coma or under surgical anesthesia). In these patients, the mouth, tongue, and larynx can obstruct normal breathing. In such cases, the auxiliary tube 90 needs to be inserted into the patient's main trachea to open the airway and provide ventilation. The second balloon 91 is inflated, and the outer wall of the auxiliary tube 90 is sealed against the main trachea to prevent oxygen or air from leaking out.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

[0072] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0073] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0075] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0076] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0077] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
