[0002] Animal bed devices are used in scientific research and are usually used in conjunction with imaging equipment to transport samples (living small animals, ex vivo organs or materials) to the scanning area where the imaging equipment is located and complete imaging scanning. Among them, the imaging equipment that is used in conjunction with the animal bed device includes: micro-computed tomography equipment (Micro CT), miniaturized positron emission tomography equipment (Micro PET) and / or single-photon emission computed tomography equipment (Micro SPECT), etc.

[0003] When the animal bed device is working, it is necessary to drive the animal cabin carrying the sample into the scanning area of ​​the imaging device and be scanned and imaged by the imaging device. For this purpose, the offset between the animal cabin and the imaging center axis of the imaging device needs to be within a preset range. At present, the installation position of the animal cabin in the existing animal bed device is fixed. However, the animal cabin will be deformed to a certain extent due to the load and its own weight in the animal bed device. Therefore, the actual offset between the animal cabin in the animal bed device and the imaging center axis of the imaging device will exceed the above-mentioned preset range, which will reduce the scanning field of view of the imaging device when scanning the sample in the animal cabin and affect the quality of the final scanning image.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] The animal bed device 100 for which protection is sought in the present application is used in conjunction with an imaging device (not shown), and when the animal bed device 100 is in operation, it can drive an animal cabin 20 carrying a sample (not shown) to extend into a scanning area of ​​the imaging device and be scanned and imaged by the imaging device.

[0037] like Figure 1As shown, an animal bed device 100 provided in an embodiment of the present application includes a bed body 10, an animal cabin 20, a driving mechanism 30 and an animal cabin support mechanism, wherein the bed body 10 is installed on an imaging device; the animal cabin 20 is used to carry samples; the driving mechanism 30 includes a guide rail 31 and a driving member (not shown), and the guide rail 31 and the driving member are both installed on the bed body 10; the animal cabin support mechanism includes a mounting seat 41, a support member 42 and an adjustable connecting assembly, wherein the mounting seat 41 is slidably mounted on the guide rail 31 and connected to the driving member, one end of the support member 42 is connected to the animal cabin 20, and the other end of the support member 42 is connected to the mounting seat 41 through an adjustable connecting assembly, so as to control the animal cabin 20 to reciprocate in a first horizontal direction driven by the mounting seat 41; wherein the mounting position of the support member 42 on the mounting seat 41 can be adjusted through the adjustable connecting assembly, so as to form a preset offset between the animal cabin 20 and the imaging center axis of the imaging device. It should be noted that the above-mentioned preset offset specifically refers to the offset between the animal cabin 20 and the imaging center axis of the imaging device that can meet the use requirements, and when the offset between the two is within the range of the preset offset, the imaging device has a sufficient scanning field of view for scanning the sample in the animal cabin 20. It should be noted that the above-mentioned first horizontal direction specifically refers to the direction parallel to the extension direction of the guide rail 31; the above-mentioned installation posture of the support member 42 on the mounting seat 41 specifically refers to the position and posture of the support member 42 on the mounting seat 41.

[0038] It can be understood that the installation position of the animal cabin 20 on the mounting seat 41 can be adjusted by an adjustable connecting component, that is, the installation position of the animal cabin 20 can be adaptively adjusted according to needs, so that it can be ensured that the offset between the animal cabin 20 and the imaging center axis of the imaging device can meet the use requirements, so that the scanning field of view of the imaging device when scanning the sample in the animal cabin 20 can be guaranteed, so that when the animal bed device 100 is used in conjunction with the imaging device, the imaging quality of the sample in the animal cabin 20 is improved when the imaging device is scanned.

[0039] like Figure 1 As shown, in some embodiments, the driving member can be specifically configured as a nut screwed onto the lead screw 32, the nut is connected and fixed to the mounting seat 41, and the rotation of the lead screw 32 is used to drive the nut to reciprocate in the first horizontal direction, and combined with the sliding connection between the mounting seat 41 and the guide rail 31, the mounting seat 41 can be driven to reciprocate in the first horizontal direction. Of course, for those skilled in the art, the driving member can also be configured as a connecting mechanism for connecting the mounting seat 41, and the mounting seat 41 can be driven directly through the connecting mechanism by a telescopic cylinder or a telescopic motor to achieve reciprocating motion of the mounting seat 41 in the first horizontal direction.

[0040] In the animal bed device 100 of the present application, the mounting seat 41 has a mounting surface (not shown), and the support member 42 can be assembled to the mounting seat 41 through the mounting surface, and the support member 42 has a supporting surface (not shown), and the mounting surface is arranged relative to the supporting surface. Since the positional relationship between the mounting surface and the supporting surface corresponds to the installation posture between the support member 42 and the mounting seat 41, in order to facilitate the description of the adjustment of the installation posture of the support member 42 on the mounting seat 41, it can be specifically presented by changing the relative positional relationship between the mounting surface and the supporting surface.

[0041] like Figure 1 , Figure 2 As shown, the adjustable connection assembly includes a first adjustable unit 50, which is mounted on the support member 42 and abuts against the mounting surface, and is used to adjust the connection position of the support surface relative to the mounting surface in the vertical direction and the deflection angle relative to the mounting surface. In other words, the first adjustable unit 50 can adjust the mounting angle and mounting height of the support member 42 on the mounting seat 41.

[0042] like Figure 2 As shown, in some embodiments, the first adjustable unit 50 includes at least three adjusting members 51, and the at least three adjusting members 51 are installed on the support member 42 at intervals and non-collinearly and abut against the mounting surface. It should be noted that the at least three adjusting members 51 are installed on the support member 42 at intervals and non-collinearly, which specifically means that the adjusting members 51 in the first adjustable unit 50 can at least enclose a triangle on the support member 42, and a plane is determined by three non-collinear points to support the installation of the support member 42 on the mounting seat 41.

[0043] Exemplarily, in some embodiments, the number of the adjusting members 51 is set to four, wherein the four adjusting members 51 are symmetrical with respect to the center of the mounting surface. That is, by controlling the contact between the four adjusting members 51 and the mounting surface on the mounting seat 41, the four adjusting members 51 can be used to lift the support member 42 from the mounting seat 41 as a whole, or the support member 42 can be driven to rotate relative to the mounting seat 41 around the first horizontal direction and / or the second horizontal direction, that is, the animal cabin 20 can be adjusted in the first horizontal direction and / or the second horizontal direction relative to the mounting seat 41 in the tilt direction and tilt angle. It should be noted that the second horizontal direction is perpendicular to the first horizontal direction.

[0044] It can be understood that the adjustment of the tilt direction and tilt angle of the support member 42 on the mounting seat 41 can be specifically achieved by adjusting the adjustment member 51 in different mounting positions. Therefore, for those skilled in the art, the adjustment member 51 can be arranged at different positions of the support member 42 according to usage requirements, and the number of adjustment members 51 at each position can also be specifically arranged according to usage requirements, which will not be elaborated here.

[0045] In order to clearly describe the working principle of how to use four adjusting members 51 to adjust the installation posture of the support member 42 on the mounting seat 41 when the first adjustable unit 50 is working, the present application sets the above four adjusting members 51 as the first adjusting member 511, the second adjusting member 512, the third adjusting member 513 and the fourth adjusting member 514. At this time, when the first adjusting member 511, the second adjusting member 512, the third adjusting member 513 and the fourth adjusting member 514 are adjusted in the same direction at the same time, the vertical translation of the support member 42 relative to the mounting surface can be achieved. If it is necessary to adjust the tilt direction and tilt angle of the support member 42 relative to the mounting seat 41, the first adjusting member 511 and the third adjusting member 513 can be adjusted in one direction, and the second adjusting member 512 and the fourth adjusting member 514 can be adjusted in the opposite direction, so that the support member 42 can be driven and adjusted to rotate around the first horizontal direction; or, the first adjusting member 511 and the second adjusting member 512 can be adjusted in one direction, and the third adjusting member 513 and the fourth adjusting member 514 can be adjusted in the opposite direction, so that the support member 42 can be driven and adjusted to rotate around the second horizontal direction. Therefore, by adjusting the four adjusting members 51, or adjusting two adjacent adjusting members 51 at the same time, the translation, tilt direction and tilt angle of the support member 42 relative to the mounting surface can be adjusted.

[0046] In some embodiments, the adjusting member 51 is connected to the supporting member 42 in a threaded manner. For example, the adjusting member 51 is set as an adjusting screw. In this way, the adjustment between the adjusting member 51 and the supporting member 42 can be facilitated, and the position of the supporting member 42 on the mounting seat 41 can be adjusted easily.

[0047] Among them, scale lines and marking lines can be marked between the adjusting member 51 and the supporting member 42. By using the indication of the marking lines on the scale lines, the rotation angle of the adjusting member 51 when it rotates on the supporting member 42 can be intuitively obtained. In this way, it is convenient to control the rotation angle of the adjusting member 51 on the supporting member 42, thereby facilitating the control of the translation, tilt direction and tilt angle adjustment of the supporting member 42 relative to the mounting surface.

[0048] like Figure 2 As shown, in some embodiments, the first adjustable unit 50 further includes a plurality of fixing members 52, and the support member 42 is provided with mounting holes 421, and the fixing members 52 can pass through the corresponding mounting holes 421 and be detachably connected to the mounting seat 41. In this way, the assembly positioning of the support member 42 on the mounting seat 41 can be achieved by utilizing the detachable connection between the fixing members 52 and the mounting seat 41, and the abutment between the adjusting member 51 connected to the support member 42 and the mounting seat 41.

[0049] Exemplarily, the fixing member 52 and the mounting seat 41 can be connected by a threaded connection, so that the fixing member 52 can fix the support member 42 on the mounting seat 41 by pressing the support member 42 against the mounting seat 41, so that the support member 42 can be easily fixed to the mounting seat 41. It should be noted that the number of the fixing members 52 can be two, three, four, or even more. Preferably, the number of the fixing members 52 is set to be the same as the number of the adjusting members 51, and the fixing members 52 are arranged adjacent to the corresponding adjusting members 51.

[0050] like Figure 2 , Figure 3 As shown, in some embodiments, the first adjustable unit 50 further includes a plurality of limit members 53, which are mounted on the mounting seat 41 and abut against the support member 42, and are used to limit the movement of the support surface relative to the mounting surface in the first horizontal direction. In other words, the support member 42 adjusted by the first adjustable unit 50 can be positioned by abutting against the limit members 53 and the support member 42.

[0051] Exemplarily, the number of the limiting members 53 is two, and the two limiting members 53 respectively abut against the two end surfaces of the support member 42 along the first horizontal direction. Of course, for those skilled in the art, the number of the limiting members 53 can also be set to three, four, or even more, and the two end surfaces of the support member 42 in the first horizontal direction can abut against the number of the limiting members 53 at the same time as needed, which can be two, three, or even more.

[0052] like Figure 2 , Figure 3 As shown, in some embodiments, the adjustable connection assembly includes a second adjustable unit 60, which is installed on the mounting seat 41 and connected to the support member 42, and is used to adjust the connection position of the support surface relative to the mounting surface in the second horizontal direction; wherein the second horizontal direction is set perpendicular to the first horizontal direction.

[0053] like Figure 3As shown, in some embodiments, the second adjustable unit 60 includes an adjustment fixing seat 61 and an adjustment rod 62, wherein the adjustment fixing seat 61 is mounted on the mounting seat 41 and is rotatably connected to the adjustment rod 62; wherein the adjustment rod 62 extends along the second horizontal direction and is threadedly connected to the support member 42. When the second adjustable unit 60 is working, the adjustment rod 62 can be driven to rotate on the adjustment fixing seat 61, and the threaded matching structure between the adjustment rod 62 and the support member 42 can be used to drive the support member 42 to reciprocate in the second horizontal direction. Of course, the connection method between the adjustment rod 62, the adjustment fixing seat 61 and the support member 42 is not limited to the above-mentioned one. For those skilled in the art, the adjustment rod 62 can also be threadedly connected to the adjustment fixing seat 61, and the adjustment rod 62 and the support member 42 are position-limited in the axial direction of the adjustment rod 62.

[0054] like Figure 3 As shown, in some embodiments, the adjustment fixing seat 61 includes a first bending plate 611 and a second bending plate 612. The first bending plate 611 is fixed to the mounting seat 41 by a first screw 101, and the second bending plate 612 is fixed to a plate portion 6111 of the first bending plate 611 away from the mounting seat 41 by a second screw 102. The adjustment rod 62 passes through the second bending plate 612 and is rotatably connected to the second bending plate 612. In this way, the adjustment rod 62 and the support member 42 can be at the same height to satisfy the driving of the support member 42 to move in the second horizontal direction while the adjustment rod 62 rotates on the second bending plate 612.

[0055] In some embodiments, one of the adjusting rod 62 and the adjusting fixed seat 61 is marked with a scale (not shown), and the other is provided with a scale indicator (not shown), and the scale indicator can cooperate with the scale to display the rotation angle of the adjusting rod 62 when it rotates on the adjusting fixed seat 61. In this way, the rotation angle of the adjusting rod 62 when it rotates on the adjusting fixed seat 61 can be intuitively obtained according to the indication of the scale lines at different positions on the scale of the scale indicator, thereby facilitating the control of the position adjustment of the support member 42 in the second horizontal direction by the adjusting rod 62. Similarly, the rotation adjustment of the adjusting member 51 on the support member 42 in the first adjustable unit 50 can also be intuitively obtained by setting a corresponding scale indicator, which will not be elaborated here.

[0056] It should be noted that the rotation angle of the above-mentioned adjusting rod 62 when it rotates on the adjusting fixed seat 61 corresponds one to one with the displacement of the support member 42 when it moves in the second horizontal direction driven by the adjusting rod 62. Therefore, by controlling the rotation angle of the adjusting rod 62 when it rotates, the displacement of the support member 42 when it moves along the second horizontal direction on the mounting seat 41 can be controlled; of course, according to the demand for the displacement amount that needs to be adjusted when the animal cabin 20 translates in the second horizontal direction, it can be achieved by controlling the density of the scale lines on the scale, which will not be elaborated here.

[0057] like Figure 3 As shown, exemplarily, a fixing ring 621 is connected to the adjusting rod 62. For this purpose, scales can be marked on the outer peripheral surface of the fixing ring 621. Accordingly, an indicating arrow (not shown) can be provided on the second bending plate 612 of the adjusting fixing seat 61. By using the indicating arrow to indicate the scale lines on the fixing ring 621, the rotation angle of the adjusting rod 62 when it rotates on the second bending plate 612 can be directly read.

[0058] like Figure 2 , Figure 3 As shown, in some embodiments, the animal bed device 100 also includes an adjustment support frame 70, which is arranged on the outer side of the support member 42 and is respectively connected to the mounting seat 41; and, the limit member 53 and the adjustment fixing seat 61 in the animal bed device 100 of the present application can be assembled to the mounting seat 41 through the adjustment support frame 70, so that the second adjustable unit 60 and the first adjustable unit 50 in the animal bed device 100 for adjusting the installation posture of the animal cabin 20 on the mounting seat 41 can be installed on the existing mounting seat 41, that is, the second adjustable unit 60 and the first adjustable unit 50 can be installed without changing the original structure of the mounting seat 41, which has the effect of reducing costs.

[0059] Exemplarily, there are two adjustable support frames 70, and the two ends of the support member 42 extending out of the limit member 53 can be detachably connected to the adjustable support frames 70 respectively, and the adjustable fixing seat 61 can select one of the adjustable support frames 70 for assembly. It should be noted that the third screw 103 can be used to detachably connect the limit member 53 and the adjustable support frame 70, as well as the adjustable fixing seat 61 and the adjustable support frame 70.

[0060] In summary, the animal bed device 100 of the present application can use the first adjustable unit 50 and / or the second adjustable unit 60 to adjust the installation position of the animal cabin 20 on the mounting seat 41 as needed. In this way, it can be ensured that the offset between the animal cabin 20 and the imaging center axis of the imaging device can meet the use requirements, thereby ensuring the scanning field of view of the imaging device when scanning the samples in the animal cabin 20, so that when the animal bed device 100 is used in conjunction with the imaging device, the imaging quality of the samples in the animal cabin 20 when scanned by the imaging device is improved.

[0061] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
