[0037] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0038] See also Figure 1 and Figure 2 The present application embodiment provides a medical device 100, which is a device used to scan a patient and generate a medical image. Figure 1 In the figure, the medical device 100 is a magnetic resonance device, which is a medical imaging device that uses the characteristics of atomic nucleus spin motion to generate image signals under radio frequency pulse excitation in an external magnetic field, and generates medical images after processing the image signals. The magnetic resonance device may include a detection device 120, a base 140, and a bed 200, wherein the detection device 120 is used to generate an external magnetic field, and is provided with a detection cavity 1210. An annular magnet (not shown in the figure) may be provided in the detection device 120 to realize the detection function. For example, the annular magnet may be a permanent magnet, a normal conductive magnet, and a superconducting magnet.

[0039] The base 140 is used to carry the hospital bed 200. In some possible embodiments, the base 140 can be fixedly connected to the detection device 120 to make the overall structure of the magnetic resonance device more solid and reliable. The base 140 can also be used to transport the hospital bed 200 so that the hospital bed can enter, exit or move in the detection cavity 1210. In other possible embodiments, the base 140 is detachably connected to the detection device 120, and a plurality of moving wheels (not shown in the figure) can be provided at the bottom of the base 140 so that the base 140 can drive the hospital bed 200 to move, thereby more conveniently carrying the patient lying on the hospital bed 200.

[0040] The bed 200 is movably connected to the base 140, and is used for the patient to lie flat or sideways. When the magnetic resonance device performs scanning, the bed 200 moves relative to the base 140 to extend into the detection cavity 1210, thereby realizing magnetic resonance imaging of the patient lying on the bed 200.

[0041] Specifically, the hospital bed 200 may be provided with one or more detection coils 2140, which may be used to transmit radio frequency pulse signals and may also be used to receive magnetic resonance signals. The detection coil 2140 may be a fixed coil, which is fixedly connected to the hospital bed 200, for example, the fixed coil may be a head and neck coil, a spine coil, etc. The detection coil 2140 may also be an external coil, which is detachably connected to the hospital bed 200, for example, the external coil may be an abdominal coil, a knee coil, etc. When the magnetic resonance device is scanning, when the external coil is needed, the external coil needs to be fixed to a designated position of the patient. For example, when magnetic resonance imaging is performed on the abdomen of the patient, the abdominal coil needs to be fixed to the abdominal position of the patient. Therefore, the hospital bed 200 needs to be provided with one or more straps 300 to fix the external coil to the patient's body. In addition, the strap 300 may also fix the patient to the hospital bed 200, thereby avoiding the situation where the imaging quality is reduced due to the change in the relative position between the patient and the detection coil.

[0042] Of course, in some other possible embodiments, the medical device 100 may also be a computed tomography (CT) device. In this case, the detection device 120 refers to a device that emits specified rays (for example, X-rays, gamma rays), which will not be elaborated in this embodiment.

[0043] In this embodiment, the bed 200 may include a bed body 210 and a strap 300. The bed body 210 is generally plate-shaped and can be moved relative to the detection device 120 to be placed in the detection cavity 1210. The bed body 210 may include a support portion 2120 and a detection coil 2140. The support portion 2120 may be movably connected to the base 140 and used to fix the detection coil 2140. Figure 2 In the illustrated embodiment, the detection coil 2140 is a spine coil, and the side of the spine coil facing away from the support portion 2120 is used for the patient to lie flat or sideways.

[0044] In this embodiment, the bed 210 is further provided with a fixing buckle 2160, which can be located at the edge of the bed 210 and is used to fix the strap 300. As an example, the fixing buckle 2160 is integrated with the bed 210, and "integrated with" here should be understood as the fixing buckle 2160 constituting a part of the structure of the bed 210, or the fixing buckle 2160 is formed by using a part of the structure of the bed 210, for example, a groove is cut on the bed 210 to form a part with a "snap-on" function and is called a "fixing buckle". As another example, the fixing buckle is a part provided on the bed, for example, a formed part is installed on the bed.

[0045] exist Figure 2In the illustrated embodiment, the fixing buckle 2160 may be integrated at an edge of the support portion 2120. In some other possible embodiments, the fixing buckle 2160 may also be integrated at an edge of the detection coil 2140 (eg, a spinal coil).

[0046] See also Figure 3 The fixing buckle 2160 may include a first side 2161 and a second side 2163 that are separated from each other, and the fixing buckle 2160 is provided with a slot 2165 that passes through the first side 2161 and the second side 2163. Figure 3 In the illustrated embodiment, the fixing buckle 2160 may be roughly plate-shaped, and the card slot 2165 runs through the opposite sides of the fixing buckle 2160. Specifically, the card slot 2165 is a groove provided on the bed 210, and the first side 2161 and the second side 2163 may be the two sides of the fixing buckle 2160 along the gravity direction, respectively, so that the connecting assembly 400 provided on the strap 300 can be kept in the card slot 2165 under the action of gravity, thereby ensuring the stability of the connection between the strap 300 and the bed 210. The specific structure of the strap 300 and the connecting assembly 400 is introduced in the following specification. Of course, the card slot 2165 may be directly a groove provided on the bed 210, and the partial structure of the bed 210 provided with the card slot 2165 may be regarded as the above-mentioned "fixing buckle 2160".

[0047] See also Figure 4 The fixing buckle 2160 may be roughly block-shaped, and the fixing buckle 2160 may also be provided with a receiving cavity 2167, which is located on the second side 2163 and communicates with the card slot 2165, and in the width direction of the card slot 2165, the size of the receiving cavity 2167 is larger than the size of the card slot 2165. In other words, the "first side 2161 of the fixing buckle 2160" is the outer wall of the fixing buckle 2160, which faces the outside; the "second side 2163 of the fixing buckle 2160" is the inner wall of the fixing buckle 2160, which is used to define the receiving cavity 2167. Here, the "width direction of the card slot 2165" may specifically be the width direction X of the bed body 210.

[0048] Therefore, when the connection component 400 is held in the card slot 2165, part of the structure of the connection component 400 can be placed in the accommodating cavity 2167. Specifically, the shape of the accommodating cavity 2167 can be adapted to the structure of the connection component 400 to improve the stability of the clamping between the connection component 400 and the fixing buckle 2160. The specific implementation of the accommodating cavity 2167 is introduced in the following description.

[0049] See also Figure 5 The card slot 2165 is generally in the shape of a long strip. The card slot 2165 may have an extension direction, which is its length direction. Figure 5In the embodiment, the card slot 1265 extends along a preset direction Y, and the preset direction Y can be the length direction of the bed 210. Specifically, the extension length of the card slot 2165 is greater than the size of the connection component 400 in the preset direction Y, and the connection component 400 can move in the card slot 2165 along the preset direction Y. Therefore, the strap 300 connected to the bed 210 can slide in the card slot 2165 through the connection component 400, and then the connection position of the strap 300 can be adjusted, so that the strap 300 can be more flexible when used to meet the scanning requirements of various different parts. In addition, when the connection component 400 is connected to the fixing buckle 2160, the connection component 400 can be fixed at any position of the card slot 2165, and then the connection position can be adjusted by sliding in the card slot 2165, so that the connection component 400 is more flexible when connected.

[0050] In some possible embodiments, the bed 210 has a first side 2101 and a second side 2103 opposite to each other, and the first side 2101 and the second side 2103 are located on opposite sides of the bed 210 in a specific direction X, and can also be considered as the left and right sides of the bed 210. The number of the fixing buckles 2160 is at least two, and at least two fixing buckles 2160 are distributed on the first side 2101 and the second side 2103. At least two fixing buckles 2160 are provided with a card slot 2165 in a one-to-one correspondence. For example, in the case where the number of the fixing buckles 2160 is two, one fixing buckle 2160 is provided on the first side 2101, and the other fixing buckle 2160 is provided on the second side 2103. In this embodiment, by providing a plurality of fixing buckles 2160 on the bed 210, the strap 300 can be more flexible when connected to the bed 210.

[0051] In this embodiment, the strap 300 is adapted to be connected to the fixing buckle 2160, which is used to fix the patient and the external coil on the bed 210. Figure 7 , the strap 300 may include a flexible strap 320 and a connecting assembly 400. The flexible strap 320 is generally in the shape of a long strip, and its material may be polyurethane synthetic leather (PU leather) or a soft material that can directly contact the patient's skin. One end of the flexible strap 320 is connected to a fixing buckle 2160 on one side of the bed 210 through the connecting assembly 400, so that the flexible strap 320 and the fixing buckle 2160 are connected. The other end of the flexible strap 320 can be fixedly connected to the other side of the bed 210, or connected to the other side of the bed 210 through another strap 300.

[0052] Please refer again Figure 2In this embodiment, the number of the straps 300 is at least two, and the at least two straps 300 include a first strap 301 and a second strap 303. One end of the first strap 301 is connected to the fixing buckle 2160 on the first side 2101, and one end of the second strap 303 is connected to the fixing buckle 2160 on the second side 2103. Specifically, one end of the first strap 301 is clamped in the clamping groove 2165 corresponding to the fixing buckle 2160 on the first side 2101, and one end of the second strap 303 is clamped in the clamping groove 2165 corresponding to the fixing buckle 2160 on the second side 2103.

[0053] The first strap 301 and the second strap 303 are detachably connected. Specifically, the first strap 301 and the second strap 303 may also be respectively provided with a detachable structure (e.g., Velcro, buckle, etc.), and the detachable structure is respectively provided at one end of the flexible belt 320 away from the connecting assembly 400. When the operator needs to tie the two straps 300 on the patient, only one end of the two straps 300 is installed on the corresponding fixing buckle 2160 through the connecting assembly 400, and the other ends of the two straps 300 are closed to the middle to be fixed by the detachable structure. In addition, the above-mentioned detachable structure can be provided in multiple in the extending direction of the flexible belt 320, so that the operator can flexibly adjust the tightness of the two straps 300 when fixed, thereby improving the patient's comfort during the test.

[0054] In this embodiment, the connection component 400 is used to be plugged into and matched with the card slot 2165. Specifically, the connection component 400 is used to connect the flexible belt 320 to the fixing buckle 2160 provided with the card slot 2165. Please refer to Figure 3 , the connection assembly 400 may include a hook member 410 and a clamping member 430. The hook member 410 may include a hook portion 4120, and the hook member 410 is used to penetrate into the slot 2165 so that the hook portion 4120 is clamped with the slot 2165. The clamping member 430 may include a main body 4320 and a clamping portion 4340 connected to each other, and the main body 4320 is movably connected to the hook member 410. The clamping member 430 can move relative to the hook member 410, so that the clamping portion 4340 can be placed in the slot 2165 to overlap with the portion of the hook member 410 located in the slot 2165, thereby limiting the hook member 410 in the slot 2165. The “limited position” here refers to the state in which the hook member 410 remains in the slot 2165 under the action of the holding member 430 , and the hook member 410 cannot be detached from the slot 2165 in the absence of external force to pull out or move the holding member 430 .

[0055] Therefore, when the flexible belt 320 is connected to the fixing buckle 2160, it is only necessary to extend the hook member 410 into the slot 2165, and then move the holding member 430 to place the holding portion 4340 into the slot 2165 when the hook portion 4120 is locked with the slot 2165, so as to limit the hook member 410. At this time, since the holding portion 4340 and part of the hook member 410 are kept in the slot 2165 and are limited by the slot 2165, it means that the connection assembly 400 basically does not have any movement margin along the width direction of the slot 2165, so that the hook member 410 remains locked with the slot 2165 and cannot be separated from the slot 2165.

[0056] Therefore, the strap 300 in this embodiment can be stably connected to the slot 2165 on the fixing buckle 2160 through the connecting assembly 400. When it is necessary to release the limit of the hook member 410, it is only necessary to operate the clamping member 430 to pull the clamping portion 4340 out of the slot 2165. At this time, the hook member 410 moves in the width direction of the slot 2165 to disengage from the slot 2165, so that the strap 300 and the fixing buckle 2160 are separated.

[0057] The strap 300 in this embodiment can be detachably inserted into the slot 2165 on the fixing buckle 2160 by providing the above-mentioned connecting component 400, so that the strap 300 can be more flexible when used to meet a variety of different fixing requirements.

[0058] In this example, see Figure 8 The hook member 410 is roughly block-shaped, which is used to connect the flexible belt 320 and is suitable for passing through the first side 2161 and being arranged in the slot 2165 and being clamped on the second side 2163 to connect the flexible belt 320 and the fixing buckle 2160.

[0059] The hook member 410 includes a hook portion 4120 and an extension portion 4140 connected to each other. The extension portion 4140 is generally in the shape of a sheet, and has a first extension surface 4141 and a second extension surface 4143 that are separated from each other. The hook portion 4120 is located on the first extension surface 4141 and protrudes relative to the first extension surface 4141, so that the side of the hook member 410 provided with the first extension surface 4141 constitutes a protruding structure. It should be noted here that the names of "hook portion" and "extension portion" are both named for the convenience of description. In a specific example, there may be a clear dividing line or no clear dividing line between the structures of the two, for example, the two are assembled together or the two are an integrally formed structure. In some possible embodiments, the hook portion 4120 and the extension portion 4140 may be an integrally formed structure, for example, the hook member 410 may be made of plastic or non-magnetic metal through injection molding or machining, and the hook portion 4120 and the extension portion 4140 are two parts at different positions on the hook member 410.

[0060] In some possible embodiments, the extension portion 4140 has a first end 4145 and a second end 4147 opposite to each other, the first end 4145 is used to connect the flexible belt 320, and the hook portion 4120 is disposed at the second end 4147 of the extension portion 4140 and protrudes relative to the extension portion 4140. The hook portion 4120 is adapted to be inserted into the slot 2165 via the first side 2161 and be clamped on the second side 2163. When the hook portion 4120 is clamped on the second side 2163, the extension portion 4140 is inserted into the slot 2165. Specifically, the protruding height of the hook portion 4120 relative to the extension portion 4140 gradually increases along the designated direction H, and the designated direction H is the direction in which the second end 4147 points to the first end 4145. The "designated direction H" here can also be understood as the extension direction of the hook member 410. Therefore, in this embodiment, the hook portion 4120 is substantially in the shape of a barb, so that the hook member 410 can be inserted into the slot 2165 more smoothly.

[0061] In some other possible embodiments, the hook portion 4120 may be recessed relative to the extension portion 4140 to form a recessed structure, and the groove wall of the slot 2165 may be provided with a protrusion adapted to the hook portion 4120. When the hook portion 4120 is engaged with the slot 2165, the protrusion is embedded in the recessed structure on the hook portion 4120. When the holding portion 4340 is placed in the slot 2165, the protrusion and the recessed structure can be clamped and retained under the action of the holding portion 4340, so that the hook portion 4120 is limited in the slot 2165.

[0062] Specifically, both the first extension surface 4141 and the second extension surface 4143 of the extension portion 4140 can be provided with a recessed structure. When the hook member 410 is extended into the slot 2165, any one of the first extension surface 4141 and the second extension surface 4143 can be engaged with the protrusion on the slot 2165 without considering the orientation of the hook member 410. This makes the connection assembly 400 simpler when connecting the fixing buckle 2160, and enables blind insertion to save operation time.

[0063] In some possible embodiments, the end of the extension portion 4140 away from the hook portion 4120 (i.e., the first end 4145) is provided with a first through hole 4149, and the flexible belt 320 is suitable for passing through the first through hole 4149 to connect to the extension portion 4140. The first through hole 4149 can pass through the first extension surface 4141 and the second extension surface 4143 of the extension portion 4140, that is, the hole axis direction of the first through hole 4149 is substantially arranged along the thickness direction of the extension portion 4140. After the end of the flexible belt 320 used for connecting the extension portion 4140 passes through the first through hole 4149, it can be fixed by sewing technology, so that the fixation between the flexible belt 320 and the extension portion 4140 is more reliable. Of course, in some other embodiments, the flexible belt 320 can also be attached to the surface of the extension portion 4140.

[0064] In some possible embodiments, the fixing buckle 2160 is provided with a receiving cavity 2167. When the hook portion 4120 is clamped on the second side 2163, the hook portion 4120 is located in the receiving cavity 2167, and the receiving cavity 2167 can protect the hook portion 4120. In some possible examples, when the hook portion 4120 is placed in the receiving cavity 2167, the surface of the hook portion 4120 can fit the inner wall of the receiving cavity 2167 to limit the hook portion 4120, so as to prevent the connection assembly 400 from swinging left and right.

[0065] In some other possible examples, the accommodating cavity 2167 may have an extension direction, and the extension direction of the accommodating cavity 2167 is consistent with the extension direction of the slot 2165. When the hook portion 4120 is placed in the accommodating cavity 2167, there may be a certain gap between the surface of the hook portion 4120 and the inner wall of the accommodating cavity 2167, so that the connecting assembly 400 can move more smoothly in the slot 2165.

[0066] Please refer again Figure 4 , the accommodating cavity 2167 can be axially symmetrical about the designated axis X. When the hook portion 4120 is clamped on the second side 2163, the direction of the designated axis X is the same as the extension direction of the extension portion 4140 (that is, the extension direction of the hook member 410). Exemplarily, the accommodating cavity 2167 can be in an inverted trapezoidal shape, a rectangular shape, etc. Therefore, the inner wall of the accommodating cavity 2167 (that is, the second side 2163) can provide two clamping surfaces for the hook portion 4120. Specifically, Figure 4The hook portion 4120 in the hook member 410 protrudes relative to the first extension surface 4141, so that the side of the hook member 410 provided with the first extension surface 4141 forms a protruding structure, and the side of the hook member 410 provided with the second extension surface 4143 is not provided with a protruding structure. Therefore, the hook member 410 is provided with a protruding structure only on one side. In this case, when the hook member 410 is extended into the slot 2165, it can abut against any holding surface without considering the orientation of the hook member 410, making it easier to connect the connection assembly 400 to the fixing buckle 2160, and blind insertion can be achieved to save operation time.

[0067] See also Fig. 9 , the clamping member 430 is roughly block-shaped, and is used to limit the hook member 410 in the clamping groove 2165. In this embodiment, the clamping member 430 may include a main body portion 4320 and a clamping portion 4340 connected to each other. Among them, the main body portion 4320 is movably connected to the extension portion 4140. For example, a guide structure (for example, a matching structure of a raised guide rail and a guide groove) may be provided between the main body portion 4320 and the extension portion 4140, so that the main body portion 4320 can move in the extension direction of the extension portion 4140. It should be noted here that the names of "main body portion" and "clamping portion" are all named for the convenience of description. In a specific example, there may be a clear dividing line or no clear dividing line between the structures of the two, for example, the two are assembled together or the two are an integrally formed structure. In some possible embodiments, the main body 4320 and the clamping portion 4340 may be an integrally formed structure. For example, the clamping member 430 may be made of plastic or non-magnetic metal through an injection molding process or machining. The main body 4320 and the clamping portion 4340 are two parts at different positions on the clamping member 430.

[0068] In some possible embodiments, the main body 4320 may be provided with a second through hole 4321, and the hole axis direction of the second through hole 4321 is substantially the same as the extension direction of the extension portion 4140. The main body 4320 is sleeved on the outer periphery of the extension portion 4140 through the second through hole 4321, and is located between the hook portion 4120 and the first through hole 4149. Specifically, the minimum width of the gap between the inner wall of the second through hole 4321 and the extension portion 4140 is less than the thickness of the flexible belt 320. For example, the inner wall of the second through hole 4321 and the surface of the extension portion 4140 can both be flat surfaces, and the "minimum width" here is the distance between the two. For another example, at least one of the inner wall of the second through hole 4321 and the surface of the extension portion 4140 is an uneven surface, in which case the "minimum width" is the minimum distance between the two surfaces. For example, the thickness of the flexible band 320 may be greater than or equal to 1 mm, and the gap between the inner wall of the second through hole 4321 and the extension portion 4140 may be less than or equal to 0.5 mm. Therefore, when manufacturing the binding band 300, the clamping member 430 may be sleeved on the hook member 410 first, and then the flexible band 320 may be passed through the first through hole 4149. The existence of the flexible band 320 may prevent the clamping member 430 from being separated from the first end 4145 of the hook member 410, thereby ensuring the normal use of the binding band 300.

[0069] In addition, when the strap 300 is removed from the hook portion 4120, the holding portion 4340 can be pulled out of the slot 2165 by holding the main body 4320. When the main body 4320 is moved to the position where the flexible belt 320 is located, the hook member 410 can be brought out of the slot 2165 by driving the flexible belt 320. Therefore, the disassembly process of the connecting assembly 400 is simpler, thereby improving the disassembly efficiency of the strap 300. Specifically, a plurality of protrusion structures can be provided on the outer surface of the main body 4320, and the plurality of protrusion structures are arranged at intervals along the extension direction of the extension portion 4140 to increase the gripping area of ​​the operator when disassembling the strap 300, so that the disassembly process of the strap 300 is smoother.

[0070] In some possible embodiments, the minimum width of the gap between the inner wall of the second through hole 4321 and the extension portion 4140 is smaller than the protruding height of the hook portion 4120. Therefore, the hook portion 4120 can prevent the retaining member 430 from being separated from the second end 4147 of the hook member 410. In other possible embodiments, please refer to Figure 8The hook member 410 may further include a limiting portion 4160, which is located at one end of the extension portion 4140 close to the hook portion 4120, between the first extension surface 4141 and the second extension surface 4143, and protrudes relative to the extension portion 4140 to form a step-like structure. When the main body 4320 is sleeved on the outer periphery of the extension portion 4140, the limiting portion 4160 and the main body 4320 are opposite to each other in the extension direction of the extension portion 4140. Therefore, in this embodiment, the main body 4320 can move along the extension direction of the extension portion 4140, and by setting the limiting portion 4160 and the main body 4320 to be arranged relative to each other, when the main body 4320 moves to the extreme position, it abuts against the limiting portion 4160, and the limiting portion 4160 can prevent the holding member 430 from being separated from the second end 4147 of the hook member 410, thereby ensuring the normal use of the strap 300.

[0071] The clamping portion 4340 is connected to the main body 4320 and is opposite to the second extension surface 4143 of the extension portion 4140. For example, the clamping portion 4340 can be overlapped on the surface of the second extension surface 4143. Specifically in this embodiment, the clamping portion 4340 is located at one end of the main body 4320 facing the hook portion 4120 and protrudes relative to the main body 4320. When the clamping portion 4340 and the extension portion 4140 are overlapped in the slot 2165, in the width direction of the slot 2165, the overall overlapped size of the two is slightly smaller than the size of the slot 2165, so that the connecting assembly 400 can slide smoothly in the slot 2165 along the preset direction Y. In addition, in the width direction of the card slot 2165, the size of the main body 4320 is larger than the size of the card slot 2165. When the holding portion 4340 is placed in the card slot 2165, the main body 4320 and the first side 2161 are in contact, that is, the main body 4320 can be "stuck" on the first side 2161. Therefore, the main body 4320 is exposed outside the card slot 2165, so that the operator can pull the holding portion 4340 out of the card slot 2165 by holding the main body 4320, thereby improving the convenience of disassembling the strap 300.

[0072] In some possible embodiments, when the hook portion 4120 is clamped on the second side 2163, the extension direction of the extension portion 4140 is the direction of gravity, and the hook portion 4120 is located at the lower end of the extension portion 4140 along the direction of gravity. That is, when the hook portion 4120 is clamped on the second side 2163, the movement direction of the clamping member 430 relative to the hook member 410 is the direction of gravity, so that the clamping member 430 can slide down under the action of gravity without manual operation by the operator to place the clamping portion 4340 into the clamping slot 2165. The fixing process of the connecting assembly 400 is simpler, thereby improving the fixing efficiency of the strap 300. In addition, the hook member 410 and the clamping member 430 can also be kept in the clamping slot 2165 under the action of gravity, thereby improving the reliability of the connection between the connecting assembly 400 and the fixing buckle 2160.

[0073] The embodiment of the present application also provides a connection assembly, which includes a hook member and a clamping member. The hook member includes a hook portion, and the hook member is used to penetrate into the slot so that the hook portion and the slot are clamped. The clamping member includes a main body and a clamping portion connected to each other, and the main body can be movably connected to the hook member; the clamping member can move relative to the hook member, so that the clamping portion can be placed in the slot to overlap with the part of the hook member located in the slot, thereby limiting the hook member in the slot. The connection assembly in this embodiment can include any one feature or a combination of multiple features of the connection assembly 400 in the above embodiment, which will not be repeated in this specification.

[0074] The embodiment of the present application also provides a binding belt, which includes a flexible belt and a connecting assembly, wherein the hook is connected to the flexible belt and is suitable for being engaged with the slot to connect the flexible belt and the fixing buckle. The connecting assembly in this embodiment may include any one or a combination of multiple features of the binding belt 300 in the above embodiment, which will not be described in detail in this specification.

[0075] The embodiment of the present application also provides a hospital bed, which includes a bed body and a strap, and the bed body is provided with a slot. One end of the strap is suitable for being clamped in the slot, and the other end of the strap is connected to the bed body. The hospital bed in this embodiment can include any one feature or a combination of multiple features of the hospital bed 200 in the above embodiment, which will not be described in detail in this specification.

[0076] In summary, the present application provides a connection assembly 400, a strap 300, a hospital bed 200 and a medical device 100. The connection assembly 400 is applied to a strap 300 having a flexible belt 320 and is used to connect the flexible belt to a fixing buckle 2160. Specifically, when the flexible belt 320 is connected to the fixing buckle 2160, it is only necessary to extend the hook member 410 into the slot 2165, and when the hook portion 4120 is locked with the slot 2165, move the holding member 430 so that the holding portion 4340 is placed in the slot 2165, so as to play the role of limiting the hook member 410. At this time, since the holding portion 4340 and the partial structure of the hook member 410 are kept in the slot 2165 and are limited by the slot 2165, it means that the connection assembly 400 basically does not have any movement margin along the width direction of the slot 2165, so that the hook member 410 remains in a state of being held by the slot 2165, and the hook member 410 cannot be separated from the slot 2165. Therefore, the strap 300 in this embodiment can be stably connected to the slot 2165 on the fixing buckle 2160 through the connection assembly 400. When it is necessary to release the limit of the hook member 410, it is only necessary to operate the holding member 430 to pull the holding portion 4340 out of the slot 2165. At this time, the hook member 410 moves in the width direction of the slot 2165 to be separated from the slot 2165, so that the strap 300 and the fixing buckle 2160 are separated.

[0077] The strap 300 in the present application can be detachably inserted into the slot 2165 on the fixing buckle 2160 by providing the above-mentioned connecting component 400, so that the strap 300 can be more flexible when used to meet a variety of different fixing requirements.
