In addition, the term “the” should be construed as including both the singular and plural forms, unless otherwise specified in the context. In addition, the term “according to” should be construed as “at least in part according to ...” and the term “based on” should be construed as “based at least in part on ...”, unless otherwise specified in the context.

[0031] Implementations of the embodiments of the present application are described below with reference to the accompanying drawings.

[0032] FIG. 1 is a schematic diagram of an X-ray imaging system according to an embodiment of the present application; As shown in FIG. 1, the X-ray imaging system 100 may be an example of a medical imaging system, and includes a floor-standing apparatus 110, a wall stand apparatus 120 and an examination table apparatus 130 provided in a scanning room 101, and a control apparatus 150 provided in a control room 102. The floor-standing apparatus 110 includes a wall stand 111, a cantilever 112, and an X-ray source assembly 113. The cantilever 112 is used to carry the X-ray source assembly 113, and the cantilever 112 is mounted on the wall stand 111.

[0033] Although some embodiments of the present application are described on the basis of a floor-standing X-ray imaging system, the embodiments of the present application are not limited thereto. For example, the medical imaging system may also be another type of X-ray imaging system, such as a movable X-ray imaging system; alternatively, the medical imagingsystem may also be another type of imaging system, such as a computerized tomography (CT) system, a positron emission tomography (PET) system, a magnetic resonance imaging (MRI) system, etc.

[0034] For ease of description, in the present application, an x-axis, a y-axis, and a z-axis are defined such that the x-axis and the y-axis are located in a horizontal plane and perpendicular to each other, and the z-axis is perpendicular to the horizontal plane. Specifically, the extending direction of the cantilever 112 or the width direction of the examination table apparatus is defined as the x-axis, the direction in the horizontal plane which is perpendicular to the extending direction of the cantilever, or the length direction of the examination table apparatus is defined as the y-axis direction, and the extending direction of the wall stand 111 is defined as the z-axis direction. That is, the z-axis direction is a vertical direction.

[0035] The floor-standing apparatus 110 further includes a guide rail mounted on the floor. The guide rail is disposed along the y-axis direction, and the wall stand 211 moves along the guide rail, i.e., along the y-axis direction. In addition, the cantilever 112 is further capable of moving along the vertical direction (i.e., the z-axis direction) relative to the wall stand 111. In addition, a driving apparatus may further be provided between the X-ray source assembly 113 and the wall stand 111. The driving apparatus may drive the X-ray source assembly 113 to rotate about the x-axis as a central axis.

[0036] The X-ray source assembly 113 includes a tube assembly, a beam limiter 114, and a tube control apparatus 115. The tube assembly is provided with an X-ray tube therein, and the X-ray tube may produce X-rays and project the X-rays to an intended region of interest (ROI) of a patient.

[0037] The beam limiter 114 is usually mounted below the X-ray tube, and the X-rays emitted by the X-ray tube irradiate on the body of a subject under examination by means of an opening of the beam limiter 117. An irradiation range of the X-rays, namely the region size of an exposure field of view (FOV), is determined by the size of the opening of the beam limiter 114. It is well known that X-rays are harmful to the human body, so it is necessary to control the X-rays so that the X-rays only irradiate the site of the object under examination that needs to be examined, namely, the region of interest (ROI).

[0038] The tube control apparatus 115 is mounted on the tube assembly. The tube control apparatus 115 includes user interfaces such as a display screen and a control button so as to be used to perform pre-capturing preparations, such as patient selection, protocol selection, positioning, etc.

[0039] The wall stand apparatus 120 includes a first detector assembly 121, a wall stand 122, and a connecting portion (not shown). The connecting portion includes a cantilever that is vertically connected in the height direction of the wall stand 122 and a rotating bracket that is mounted on the cantilever. The first detector assembly 121 is mounted on the rotating bracket. The wall stand apparatus 120 further includes a detector driving apparatus that is arranged between the rotating bracket and the first detector assembly 121. The first detector assembly is driven by the detector driving apparatus to move in a direction parallel to the height direction of the wall stand 122 in the plane supported by the rotating bracket, and the first detector assembly 121 may further be rotated relative to the cantilever to form an angle with the wall stand. The first detector assembly 121 has a plate-like structure, the orientation of which is variable, facilitating an X-ray incident surface to become vertical or horizontal depending on the incident direction of the X-rays.

[0040] A table board 131 and a second detector assembly (not shown) are included on the examination table apparatus 130. The selection or use of the first detector assembly 121 and the second detector assembly may be determined on the basis of an image capture site of a patient and / or an image capture protocol, or may be determined on the basis of the location of the subject under examination obtained by image capture of a camera, so as to perform image capture and examination in a lying or standing position. FIG. 1 only shows an example diagram of a wall stand and an examination table. It should be understood by those skilled in the art that any form or arrangement of wall stand and / or examination table may be selected, or only the wall stand may be mounted, and that the wall stand and / or examination table are / is not intended to limit the overall solution of the present application.

[0041] In some embodiments, the control apparatus 150 may include a source controller and a detector controller. The source controller is used to command an X-ray source to emit X-rays for image exposure. The detector controller is used to select a suitable detector from among a plurality of detectors and to coordinate the control of various detector functions, such asautomatically selecting a corresponding detector according to the position or pose of the subject under examination. Alternatively, the detector controller may perform various signal processing and filtering functions, specifically, for initial adjustment of a dynamic range, interleaving of digital image data, and the like. In some embodiments, the control apparatus 150 may provide power and timing signals for controlling the operations of the X-ray source and the detectors.

[0042] In some embodiments, the control apparatus 150 may further be configured to use a digitized signal to reconstruct one or more required images and / or determine useful diagnostic information corresponding to the patient, wherein the control apparatus 150 may include one or more dedicated processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other appropriate processing apparatuses.

[0043] Certainly, the medical imaging system may also include other numbers or configurations or forms of control apparatuses. For example, the control apparatus may be local (e.g., co-located with one or more X-ray imaging systems 100, e.g., within the same facility and / or the same local network). In other implementations, the control apparatus may be remote, and thus only accessible by means of a remote connection (for example, by means of the Internet or other available remote access technologies). In a specific implementation, the control apparatus may also be configured in a cloud-like means, and may be accessed and / or used in a means that is substantially similar to the means by which other cloud-based systems are accessed and used.

[0044] The system 100 further includes a storage apparatus (not shown in the figure). A processor may store the digitized signal in a memory. For example, the memory may include a hard disk drive, a floppy disk drive, an optical disk-read / write drive, a digital versatile disc drive, a flash drive, and / or a solid-state memory. The memory may also be integrated together with the processor to effectively use the footprint and / or meet anticipated imaging requirements.

[0045] The system 100 further includes an input apparatus 160. The input apparatus 160 may include a specific form of operator interface, such as a keyboard, a mouse, a voice-activated control apparatus, a touchscreen (which may also be used as a display apparatus described later), a tracking ball or any other suitable input device. An operator may input an operation signal / control signal to the control apparatus by means of the input apparatus 160.

[0046] The system 100 further includes the display apparatus 151 (such as a touch screen or a display screen). The display apparatus 151 may be used to display an operation interface such as a list of subjects under examination, positioning or exposure settings of subjects under examination, and images of subjects under examination.

[0047] In the X-ray imaging system as shown in FIG. 1, the floor-standing apparatus 110 includes the following movements: movement of the wall stand along the length direction (y- axis) of the examination table, rotational movement of the wall stand, movement of the X-ray source assembly driven by the cantilever along the vertical direction (z-axis) and the width direction (x-axis), and angular movement and tilting movement of the tube assembly. Different movements have different functional requirements. For example, in orthopedic examinations, some special positioning is required, and the tilting movement of the tube assembly is particularly necessary.

[0048] FIG. 2 is a schematic diagram of an existing tube clamp, FIG. 3 is a schematic diagram of an existing tube, and FIG. 4 is a schematic diagram of assembling an existing tube assembly. As shown in FIGS. 2 to 4, the tube assembly 200 includes a tube 201 and a clamp 301 (hose clamp), the tube 201 has two protruding portions 202 (two edges), and the clamp 301 is composed of a two-part structure. As shown in FIG. 4, during installation, the protruding portion 202 is placed in an engaging portion 302 of a part of a clamp 3011, and then the remaining part of the clamp 3012 is assembled with the foregoing part of the clamp so that the clamp holds the tube. The tube 201 slides and rotates in the clamp 301 while being in surface contact with the clamp 301. The principle of realizing the tilting movement is as follows: after the tube is turned by a required angle, two knobs 303 are screwed into (threadedly connected to) the clamp by hand. FIG. 5 is a cross-sectional view of an existing clamp. As shown in FIG. 5, the front end of the knob 303 is pressed against the front surface of the protruding portion 202, and the tube is subjected to the pressure from the front surface, thereby fixing the tube to maintain the current movement. When the tilting movement is required again, the knob is loosened by hand and the above operations are repeated.

[0049] Assuming that the current thread is M8, in the case of tightening the knob 303, the required torque is 24 Nm, and the knob radius is usually about 15 mm (when the knob is held by a finger or hand to rotate, the lever arm = 0.015 m), which means that the finger force shouldreach 24 / 0.015 = 1600 N to tighten the knob. This cannot be achieved by the rotation of normal fingers or hands. Therefore, there is always a problem that the tube is loosened and misaligned.

[0050] In addition, the space limitation makes the diameter of the knob not too large.Therefore, the above force cannot be reduced by increasing the radius, which also means that it is inconvenient to hold with fingers or hands and is not ergonomic. Moreover, the operation of tightening the knob needs to be operated back and forth on two sides of the product, resulting in poor operation experience. When the tube is tilted back to a required default position, it is also necessary to visually confirm an alignment state, which is both inaccurate and inconvenient. Furthermore, when the tube is locked, the tube may be damaged due to the pressure applied from the front surface to the tube.

[0051] In order to solve the above problems or at least similar problems, the embodiments of the present application provide a tube locking apparatus, a tube assembly, and a medical device.

[0052] The embodiments of the present application are specifically described below.

[0053] An embodiment of the present application provides a tube locking apparatus. FIG. 6 is a schematic diagram of the tube locking apparatus according to the embodiment of the present application, FIG. 7 is a cross-sectional view of the tube locking apparatus according to the embodiment of the present application along an extending direction of a tube, and FIG. 12 is a schematic diagram of assembling the tube locking apparatus and the tube according to the embodiment of the present application. As shown in FIGS. 6 and 7, the apparatus includes:

[0054] a tube clamp 41 for holding a tube, the tube clamp having a through hole 411;

[0055] a pressing block 42 having an accommodating portion 421 ; and

[0056] a connecting portion 43 passing through the through hole 411, a part of the connecting portion 43 being accommodated in the accommodating portion 421, and when the connecting portion 43 is rotated, the pressing block 42 pressing or moving away from the tube to lock or release the tube.

[0057] In some embodiments, reference may be made to the tube 201 in FIG. 3 for the structure of the tube. The tube clamp 41 may be disassembled into a first partial clamp 412 and a second partial clamp 413 (for example, the tube clamp 41 may be a hose clamp, which is formed by joining two half hose clamps, and both the two half hose clamps are in a semi-circularring shape). The first partial clamp 412 and the second partial clamp 413 each have bent portions (steps) 414 in a semi-circular ring shape. During assembly, as shown in FIGS. 6 and 7, (two) protruding portions 202 are placed on (two) bent portions 414 of the second partial clamp 413, and then, the bent portions of the first partial clamp 412 are buckled on the protruding portions 202 and assembled with the second partial clamp 413. The bent portions of the tube clamp 41 are in contact with the protruding portions of the tube, and the assembled structure is shown in FIG. 12, so that the tube clamp 41 holds the tube.

[0058] In some embodiments, as shown in FIG. 3, the protruding portion 202 is in a shape of a prism, and the prism-shaped protruding portion is disposed along a circumferential direction of the tube sleeve of the tube. The first partial clamp 412 and the second partial clamp 413 are assembled to form the bent portion 414 in the semi-circular ring shape, and the bent portion 414 is buckled on the protruding portion along the circumferential direction of the tube sleeve of the tube. The protruding portion 202 has a front surface and two side surfaces, and the bent portion of the tube clamp 41 is in contact with the front surface and one side surface, wherein the one side surface may be a surface close to the outside, so that the tube clamp 41 holds the tube.

[0059] In some embodiments, the second partial clamp 413 is provided with a through hole 411. The through hole 411 extends in the length direction of the connecting portion described later in FIG. 7, and penetrates the second partial clamp 413. The opening position of the through hole 411 is away from the front surface of the protruding portion. For example, the opening position of the through hole 411 cannot be located on a part of the bent portion 414 of the second partial clamp 413 that is in contact with the outer side surface of the protruding portion.

[0060] In some embodiments, the second partial clamp 413 may be provided with two symmetrical through holes at positions corresponding to the two protruding portions, or the second partial clamp 413 is only provided with one through hole at a position corresponding to one protruding portion, and the embodiments of the present application are not limited thereto.

[0061] In some embodiments, the pressing block 42 has an accommodating portion 421, an inner peripheral side of the accommodating portion 421 is threaded, and the through hole and the accommodating portion are the same in shape. For example, the shape may be circular.During installation, the pressing block may be pressed toward the inner side of the second partialclamp 413, and the positions of the through hole and the accommodating portion are aligned. When the pressing block is pressed toward the inner side of the second partial clamp 413, a partial area of one end of the pressing block is in contact with the inner side surface of the protruding portion 202 (the pressing block and the second partial clamp may have a gap and are not in contact), that is, two surfaces of the three surfaces of the protruding portion 202 are in contact with the bent portion 414, and the other surface is in contact with the pressing block 42. The accommodating portion 421 may be a through hole penetrating the pressing block or a groove not penetrating the pressing block, and the embodiments of the present application are not limited thereto.

[0062] In some embodiments, one pressing block may be disposed at each of the positions of the second partial clamp 413 corresponding to the two protruding portions, and the two pressing blocks are mounted on the inner side of the second partial clamp 413 corresponding to the two protruding portions, respectively, or one pressing block is only disposed on the position of the second partial clamp 413 corresponding to one protruding portion, and the embodiments of the present application are not limited thereto. The pressing block may be made of a material with relatively high hardness, such as metal, which will not be exemplified herein.

[0063] In some embodiments, the connecting portion 43 may be elongated, and one end of the connecting portion 43 is provided with threads matching the threads on the inner peripheral side of the accommodating portion. FIG. 8 is a schematic diagram of the connecting portion 43 according to an embodiment of the present application. As shown in FIG. 8, the connecting portion 43 has a first column portion 61 and a second column portion 62 which are integrally formed and have different outer diameters. The cross-sectional size of the first column portion 61 is the same as that of the through hole and the accommodating portion. A part (or all) of the first column portion 61 has threads matching threads of the accommodating portion, and the remaining part is smooth. When the pressing block is pressed to the inner side of the second partial clamp 413, the first column portion 61 first passes through the through hole 411, the first column portion 61 with threads enters the accommodating portion, and the smooth part enters the through hole. When the accommodating portion is a through hole penetrating the pressing block, one end of the first column portion 61 may pass through the accommodating portion (penetrate the pressing block), and the remaining part of the first column portion 61 is accommodated in the accommodating portion. When the accommodating portion is a groovethat does not penetrate the pressing block, the first column portion 61 does not penetrate the pressing block, and the first column portion 61 is entirely accommodated in the accommodating portion. The cross-sectional area of the second column portion 62 may be circular or other shapes, and the embodiments of the present application are not limited thereto, as long as the rotation of the second column portion 62 in the through hole is ensured. However, the cross- sectional area of the second column portion 62 is larger than the cross-sectional area of the first column portion 61, so that the second column portion 62 does not enter the through hole.

[0064] The working principle of the tube locking apparatus will be described below.

[0065] In some embodiments, after the tube is rotated by a required angle, the second column portion 62 of the connecting portion 43 is rotated in the first direction, and the threads of the first column portion 61 are connected to the threads of the accommodating portion. After the second column portion is rotated by a certain angle, the pressing block is pressed against the inner side surface of the protruding portion by the force of the thread engagement, that is, the pressing block applies pressure to the inner side surface of the protruding portion, and the pressing block and the tube clamp clamp the protruding portion, thereby fixing the tube to maintain the current angle to lock the tube. When the tilting movement is required again, the second column portion 62 of the connecting portion 43 is rotated in a second direction opposite to the first direction, the threads are unlocked, and the pressing block moves away from the inner side surface of the protruding portion to release the tube. The above operations are repeated at this time. The first direction may be an upward rotation, and the second direction may be a downward rotation, or vice versa, specifically depending on the threading direction, and the embodiments of the present application are not limited thereto.

[0066] Other variations of the tube locking apparatus according to the embodiments of the present application will be described below.

[0067] In some embodiments, the tube locking apparatus further includes: a cushioning component 45 located between the pressing block and the protruding portion. FIG. 9 is a schematic diagram of the structure of a pressing block according to an embodiment of the present application. As shown in FIG. 9, in addition to the accommodating portion 421 (for example, a through hole), the pressing block 42 is provided with a groove 422 on the foregoing partial area (an area in contact with the inner side surface of the protruding portion), and thecushioning component 45 may be embedded into the groove 422 and fixed in the groove by means of glue or other means. When the pressing block is pressed against the inner side of the second partial clamp 413, the cushioning component 45 is in contact with the inner side surface of the protruding portion, and the cushioning component 45 may be made of a wear-resistant material such as plastic, but the embodiments of the present application are not limited thereto. By means of the cushioning component, it is possible to increase the frictional force, improve the wear resistance, avoid damage to the protruding portion of the tube due to excessive pressure, and improve the locking ability by the frictional force.

[0068] In some embodiments, as shown in FIGS. 7 and 9, the tube clamp further has a first guide hole 415, and the pressing block further has a second guide hole 423. The pressing block further has a guide component 46. A part of the guide component 46 is located in the first guide hole, and another part is located in the second guide hole. The guide component 46 is integrated with the pressing block 42, and another part of the guide component 46 is fixed in the second guide hole. During installation, the guide component on the pressing block is inserted into the first guide hole, and then the pressing block is pressed against the inner side surface of the protruding portion. By means of the guide component 46, it is possible to prevent the position of the pressing block from shifting, so that the pressing block moves away from or approaches the inner side surface of the protruding portion in the length direction of the connecting portion. The guide component may be made of metal or plastic, and the embodiments of the present application are not limited thereto.

[0069] In some embodiments, a groove 416 is further provided on a side of the tube clamp 41 (the second partial clamp 413) in contact with the pressing block. FIG. 13 is a schematic diagram of a groove on the tube clamp 41 according to an embodiment of the present application. As shown in FIG. 13, the groove 416 has the same shape as the pressing block, and the pressing block may be pressed into the groove 416 during installation. By means of the limiting function of the groove 416, it is possible to prevent the position of the pressing block from shifting, so that the pressing block moves away from or approaches the inner side surface of the protruding portion in the length direction of the connecting portion. The groove 416 and the guide component 46 may be implemented individually or in combination, and the embodiments of the present application are not limited thereto.

[0070] In some embodiments, the tube locking apparatus further includes: a grip portion 47 fixed to the other end of the connecting portion and used to rotate the connecting portion. FIG. 10 is a schematic diagram of a grip portion according to an embodiment of the present application. As shown in FIG. 10, the grip portion has a penetrating hole 471 with a cross- sectional shape the same as that of the other end of the connecting portion, and the other end of the connecting portion is inserted into the penetrating hole 471. The grip portion may be a structure similar to a wrench, and the length of the grip portion may be determined as needed, but the embodiments of the present application are not limited thereto. The connecting portion is rotated by means of the grip portion, and the larger length of the grip portion is equivalent to an increased lever arm. Thus, when the tube is locked, a smaller force is applied, which can improve the convenience.

[0071] In some embodiments, as shown in FIG. 8, the cross section of the other end of the connecting portion (the second column portion 62) is polygonal. For example, the shape may be a quadrangle, a hexagon, an octagon, or the like. The cross section of the penetrating hole 471 has the same shape and size as those of the cross section of the other end of the connecting portion, so that the polygonal edge can position the grip portion, and the grip portion can be prevented from falling off in the circumferential direction of the connecting portion.

[0072] In some embodiments, the grip portion may also be provided with a fixing hole 472 with threads. When the other end of the connecting portion is inserted into the penetrating hole 471, a screw is screwed into the fixing hole, and the screw will apply pressure to a plane where one side of the polygon of the second column portion is located, and the grip portion is positioned in the length direction of the connecting portion, thereby further preventing the grip portion from falling off from the length direction of the connecting portion and preventing the grip portion from being lost. This is only an example for description, and the embodiments of the present application are not limited thereto. For example, the grip portion may also be fixed by means of glue bonding or the like, which will not be exemplified herein. According to the principle of thread engagement, when the threads are completely tightened, the rotation angle is about 40° to 50°. Therefore, during installation, the grip portion may be first placed at a suitable position (a position convenient for hand operation), and then the screw is screwed into the fixing hole.

[0073] In some embodiments, one connecting portion and one grip portion may be provided, and the connecting portion and the grip portion may be provided at a position of the clamp corresponding to one protruding portion to penetrate one through hole. The side on which the connecting portion and the grip portion are specifically provided may be determined according to the position of the wall stand. Alternatively, two connecting portions and two grip portions may be provided, which are respectively provided at positions of the clamp corresponding to the two protruding portions, and the embodiments of the present application are not limited thereto.

[0074] In some embodiments, one connecting portion and two grip portions may be provided. The connecting portion may extend and pass through two through holes at positions of the clamp corresponding to the two protruding portions at the same time, and also needs to pass through the accommodating portion (the accommodating portion is a through hole) of the pressing block. The two grip portions are provided at two end portions of the connecting portion, respectively, and the two end portions are similar in structure, as shown in FIG. 11, which will not be described in detail here. The difference from the foregoing embodiments is that the threads of the connecting portion are no longer located at one end of the connecting portion, but are located closer to the middle thereof. The locking principle is the same as in the foregoing embodiments. By providing two grip portions, the tube can be locked or released from two directions.

[0075] The assembly process of the tube locking apparatus will be described below in conjunction with the above components.

[0076] During assembly, the tube protruding portion 202 is placed on the bent portion 414 of the second partial clamp 413, and then, the bent portion of the first partial clamp 412 is buckled on the protruding portion 202 and assembled with the second partial clamp 413. The pressing block with the cushioning component and the guide component is placed at the corresponding position of the second partial clamp 413. The connecting portion is sequentially inserted into the through hole and the accommodating portion on the tube clamp. The grip portion is placed on the other end of the connecting portion, and after a suitable position is found, the grip portion is fixed on the connecting portion. The number of pressing blocks, connecting portions and grip portions that are specifically installed may be determined as needed, which will not be described in detail here.

[0077] According to the embodiments of the present application, the connecting portion sequentially passes through the through hole and the accommodating portion, and when the connecting portion is rotated, the pressing block presses or moves away from the tube to lock or release the tube. The locking force of the tube clamp is much greater than that of the existing tube clamp, which greatly reduces the occurrence of misalignment problems, reduces the risk of repeated X-ray exposure to patients, and better meets the clinical needs. In addition, the existing tube clamp is less modified without occupying more space and electrical components, thereby reducing the cost.

[0078] In addition, when the connecting portion is rotated, the pressing block presses or moves away from the protruding portion of the tube. Therefore, the direction of the locking force is changed compared with the existing tube clamp, and even in the case in which the locking force is increased, there is no influence on the tube body.

[0079] In addition, the cushioning component located between the pressing block and the protruding portion can increase the frictional force, improve the wear resistance, avoid damage to the protruding portion of the tube due to excessive pressure, and improve the locking ability by the frictional force.

[0080] In addition, by means of the guide component 46, it is possible to prevent the position of the pressing block from shifting, so that the pressing block moves away from or approaches the inner side surface of the protruding portion in the length direction of the connecting portion.

[0081] In addition, by means of the limiting function of the groove 416, it is possible to prevent the position of the pressing block from shifting, so that the pressing block moves away from or approaches the inner side surface of the protruding portion in the length direction of the connecting portion.

[0082] In addition, the connecting portion is rotated by means of the grip portion, and the larger length of the grip portion is equivalent to an increased lever arm. Thus, when the tube is locked, a smaller force is applied, which can improve the convenience.

[0083] In addition, the other end of the connecting portion has a polygonal cross section. The polygonal edges can position the grip portion, and the grip portion can be prevented from falling off in the circumferential direction of the connecting portion.

[0084] In addition, the grip portion is positioned in the longitudinal direction of the connecting portion by means of the fixing hole of the grip portion, so that the grip portion is further prevented from falling off in the longitudinal direction of the connecting portion, and the grip portion is prevented from being lost.

[0085] In addition, the tube clamp has two through holes; and the connecting portion passes through the two through holes at the same time. It is possible to lock or release the tube from two directions.

[0086] The embodiments of the present application further provide a tube assembly, which includes a tube and the tube locking apparatus in the foregoing embodiments. For the installation manner and positional relationship of the tube and the tube locking apparatus, reference may be made to the description of the foregoing embodiments, and they will not be described in detail here.
