Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a small animal optical imaging support assembly. Background Art

[0002] In most medical experiments, a fixing bracket is often needed to fix small animals. As recorded in the text of a slit lamp laser photocoagulation small animal bracket with the Chinese patent publication number CN102488566B, there is a support plate arranged vertically and rotatable around the vertical axis. The small animal is fixed on the plate surface of the support plate, so as to observe the small animal during the experiment. Similarly, in the experiment of obtaining the signs of small animals by imaging, the small animals also need to be fixed. Most of the existing imaging devices are arranged with a rotatable loading platform for placing objects or animals to be imaged, etc., as recorded in the text of an object three-dimensional imaging device with the Chinese patent publication number CN205921704U. In the existing small animal imaging experiments, the above support plate is often fixed on the above loading platform for imaging data collection. In the experiment of small animal imaging, it is often necessary to collect imaging data of as many small animals as possible for comparison. Therefore, small animals are fixed on both the front and back sides of the support plate, and the optical imaging data of the small animals on both the front and back sides can be collected by rotating the loading platform by 180°. However, since the small animals are in a living state, after the small animals are fixed on the front side of the support plate, it is impossible to press the small animals on the front side onto the table surface for the fixation operation of another small animal on the back side of the support plate. Therefore, the support plate can only be placed vertically. However, the living small animals will struggle and move around during fixation, which often leads to the problem that it is difficult to fix and tie the small animals on the vertically placed support plate. Therefore, it is urgent to solve this problem. Summary of the Utility Model

[0007] As a further solution of the present utility model: a concave receiving ring groove is coaxially arranged at the top end of the chassis. In a top-down view, the support plate is located inside the outer edge of the receiving ring groove.

[0008] As a further solution of the present utility model: a plug block that is inserted into and forms a rotation prevention fit with the loading platform of the imaging device is coaxially fixed at the bottom of the chassis.

When the two single plates are in the working state, the two butt joint screw holes are coaxially distributed, and the two single plates are locked in the working state by screwing a fastening bolt into the two butt joint screw holes.

[0010] As a further solution of the present utility model: an anesthesia mechanism is arranged on the side where the single plate is located on its working surface side, and the discharge path of the anesthesia medium discharge hole of the anesthesia mechanism points to the corresponding working surface.

[0012] As a further solution of the present utility model: adjacent anesthesia medium discharge holes on the anesthesia mechanism are communicated with each other through a medium channel. An air inlet joint communicated with any anesthesia medium discharge hole is arranged on the anesthesia mechanism. An adjusting air hole intersecting with the medium channel is also arranged on the anesthesia mechanism, and an adjusting piston that can be inserted into the medium channel and adjust the flow rate of the medium channel is arranged in the inner cavity of the adjusting air hole.

[0013] As a further solution of the present utility model: a three-way joint is further included. The three-way joint includes an air inlet connection head and two air outlet connection heads, and the two air outlet connection heads are respectively connected to the air inlet joints on two anesthesia mechanisms through rubber hoses.

[0014] As a further solution of the present utility model: the connection mode between the chassis and the support plate is bolt connection.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The support plate is composed of two single plates hinged at the same end to each other. The two single plates have a loading state where they are rotated and unfolded so that their plate surfaces are arranged side by side, and a working state where they are rotated and folded so that their inner plate surfaces are in contact. The outer plate surfaces of the two single plates in the working state form a working surface for fixing small animals. When it is necessary to load small animals on the working surface, the two single plates are rotated and unfolded to the loading state where the plate surfaces are arranged side by side. At this time, the two working surfaces are on the same plane. Thereafter, the two working surfaces are turned upwards, and the two single plates in the loading state are laid flat on the tabletop, and one small animal can be fixed on each of the two working surfaces respectively. After forming the working state later, the two small animals can be on the opposite plate surfaces, which is very convenient and fast to use. Thus, the support plate structure can conveniently fix two small animals on the two working surfaces, effectively improving the efficiency of fixing multiple small animals.

[0017] 2. When the plate surface of the support plate is arranged vertically, a chassis that can be detachably fixed to the load platform of the imaging device in a coaxial connection is provided at the bottom of the support plate. In a top-down view, the support plate is located inside the outer edge of the chassis, and the chassis can be used as a receiving tray for the excrement of small animals to prevent the excrement of small animals from contaminating the load platform.

[0018] 3. The cavity of the receiving ring groove on the chassis is used to receive the excrement of small animals, and the collection effect is better, further preventing the excrement of small animals from contaminating the load platform and providing better imaging conditions for subsequent imaging.

[0019] 4. The connection method of inserting the insert block into the load platform to form an anti-rotation fit is used, which is convenient for disassembly and assembly and can also ensure the coaxial rotation of the chassis and the load platform, effectively improving the efficiency of chassis disassembly and assembly.

[0020] 5. The connection method of using the fastening bolt and the docking screw hole is used to lock the two single plates in the working state, which is stable and convenient for fixing.

[0021] 6. An anesthesia mechanism is provided on the side of the single plate where its working surface is located. The discharge path of the anesthesia medium discharge hole of the anesthesia mechanism points to the corresponding working surface, and the small animals on the working surface can be anesthetized to prevent the small animals from struggling during imaging and affecting the imaging effect.

[0022] 7. The working surface is divided into at least two linearly arranged working areas, and at least two linearly arranged anesthesia medium discharge holes are provided on the anesthesia mechanism. When the volume of the small animals is small, at least two small animals can be fixed on one working surface, and it is ensured that each small animal on the working surface can be anesthetized.

[0023] 8. The adjacent anesthesia medium discharge holes on the anesthesia mechanism are communicated with each other through a medium channel. Therefore, only an air inlet joint communicated with any anesthesia medium discharge hole needs to be arranged on the anesthesia mechanism to ensure that the anesthesia medium discharge holes on the anesthesia mechanism can all discharge the anesthesia medium. In addition, an adjustment air hole intersecting with the medium channel is arranged on the anesthesia mechanism, and an adjustment piston that can be inserted into the medium channel to adjust the flow rate of the medium channel is arranged in the inner cavity of the adjustment air hole, so that the anesthesia medium can be distributed as needed without causing waste of the anesthesia medium.

[0024] 9. The support assembly further includes a three-way joint. The three-way joint includes an air inlet connection head and two air outlet connection heads. The two air outlet connection heads are respectively connected with the air inlet joints on the two anesthesia mechanisms through rubber hoses.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] For the convenience of understanding, the specific structure and working mode of the present invention are further described as follows in conjunction with the drawings:

[0033] The specific structure of the present utility model is referred to Figures 1-4 as shown. Its main structure includes a support plate 20 for fixing small animals. Among them, the support plate 20 is composed of two single plates 21 hinged at the same end to each other. The two single plates 21 have a loading state in which they are rotated and unfolded so that the plate surfaces are arranged side by side and a working state in which they are rotated and folded so that the inner plate surfaces are attached to each other. The outer plate surfaces of the two single plates 21 in the working state form a working surface for fixing small animals. When it is necessary to load small animals on the working surface, the two single plates 21 are rotated and unfolded to the loading state in which the plate surfaces are arranged side by side. At this time, the two working surfaces are on the same plane. Thereafter, the two working surfaces are turned upwards, and the two single plates 21 in the loading state are laid flat on the tabletop, and then one small animal can be fixed on each of the two working surfaces respectively. After the working state is formed later, the two small animals can be located on the opposite plate surfaces, which is very convenient and fast to use. After the small animals are fixed, the two single plates 21 are rotated to the working state, and the working state of the two single plates 21 is maintained by the fixing part. At this time, the two single plates 21 in the working state are fixed on the loading platform, and by using the rotation of the loading platform, imaging acquisition can be realized for the small animals on the two working surfaces.

[0034] On the above basis, as Figure 1 and Figure 2 shown, when the plate surface of the support plate 20 is vertically arranged, a chassis 10 that can be detachably fixed to the loading platform of the imaging device coaxially is fixed at the bottom of the support plate 20, and the vertical center line of the support plate 20 coincides with the axis of the chassis 10. By using the chassis 10 to connect with the loading platform, it is convenient to quickly assemble the support plate 20 and the loading platform, and by coaxially fixing the chassis 10 and the loading platform, the vertical center line of the support plate 20 can coincide with the axis of the loading platform, so as to ensure the stable position of the two working surfaces at the acquisition end of the imaging system during the rotation of the support plate 20. In addition, from a top view perspective, the support plate 20 is located inside the outer edge of the chassis 10, and the chassis 10 can be used as a receiving tray for the excrement of small animals to prevent the excrement of small animals from polluting the loading platform.

[0035] Furthermore, as Figure 1 shown, a concave receiving ring groove 11 is coaxially arranged at the top end of the chassis 10. From a top view perspective, the support plate 20 is located inside the outer edge of the receiving ring groove 11. By using the cavity of the receiving ring groove 11 to receive the excrement of small animals, the collection effect is better, and further prevent the excrement of small animals from polluting the loading platform.

[0036] Specifically, as Figure 4 shown, a plug 12 that is coaxially fixed to the bottom of the chassis 10 and is inserted into the loading platform of the imaging device and forms an anti-rotation fit is provided. By using the connection method of inserting the plug 12 into the loading platform to form an anti-rotation fit, the disassembly and assembly are convenient and can also ensure the coaxial rotation of the chassis 10 and the loading platform, effectively improving the disassembly and assembly efficiency of the chassis 10.

[0037] On the basis above, as Figure 1 shown, the fixing part includes docking screw holes 22 respectively opened on two single boards 21. When the two single boards 21 are in the working state, the two docking screw holes 22 are coaxially distributed, and are screwed with fastening bolts to lock the two single boards 21 in the working state. Using the connection method of the fastening bolts and the docking screw holes 22 to lock the two single boards 21 in the working state is stable, convenient and fast. Of course, in actual implementation, the fixing part can also adopt structures such as U-shaped pins, U-shaped buckles or binding wires in the prior art, as long as the two single boards 21 in the working state can be locked.

[0038] It is worth mentioning that to prevent small animals from struggling during imaging and affecting the imaging effect, as Figure 1 shown, an anesthesia mechanism 30 is provided on the side where the single board 21 is located on its working surface. The discharge path of the anesthesia medium discharge hole 33 of the anesthesia mechanism 30 points to the corresponding working surface, and the anesthesia medium is discharged onto the working surface by the anesthesia mechanism 30 to anesthetize small animals.

[0039] Furthermore, as Figure 1 shown, the working surface is divided into at least two linearly arranged working areas. When the volume of small animals is small, at least two small animals can be fixed on one working surface, further improving the efficiency of imaging acquisition. In addition, as Figure 3 shown, in order to ensure that small animals on each working surface can be anesthetized, the linear arrangement path of the working area is perpendicular to the discharge path of the anesthesia medium discharge hole 33. At least two linearly arranged anesthesia medium discharge holes 33 are provided on the anesthesia mechanism 30, and the discharge paths of the anesthesia medium discharge holes 33 correspond to the working areas one by one.

[0040] Even further, as Figure 1 and Figure 3As shown, the adjacent anesthesia medium discharge holes 33 on the anesthesia mechanism 30 are communicated with each other through a medium channel. Therefore, only by providing an air inlet joint 31 on the anesthesia mechanism 30 that is communicated with any anesthesia medium discharge hole 33, it can be ensured that the anesthesia medium discharge holes 33 on the anesthesia mechanism 30 can all discharge the anesthesia medium. In addition, an adjustment air hole 32 intersecting with the medium channel is provided on the anesthesia mechanism 30, and an adjustment piston 34 that can be inserted into the medium channel to adjust the flow rate of the medium channel is arranged in the inner cavity of the adjustment air hole 32. When the amount of anesthesia medium required by small animals in different work areas is different, by adjusting the insertion depth of the adjustment piston 34 in the adjustment air hole 32, the flow rates of different anesthesia medium discharge holes 33 can be controlled. In addition, when small animals are not fixed in some work areas, by completely cutting off the medium channel with the adjustment piston 34, the flow rate of the medium channel can be reduced to zero, so that the anesthesia medium discharge holes 33 in the corresponding work areas will not discharge the anesthesia medium, and the waste of the anesthesia medium can be avoided.

[0041] Specifically, as Figure 1 shown, the support assembly further includes a three-way joint 40. The three-way joint 40 includes an air inlet connector 41 and two air outlet connectors 42. The two air outlet connectors 42 are respectively connected to the air inlet joints 31 on the two anesthesia mechanisms 30 through rubber hoses. After the anesthesia medium is introduced into the air inlet connector 41 of the three-way joint 40, the anesthesia medium is respectively introduced into the two anesthesia mechanisms 30 by the two air outlet connectors 42, so that at least one anesthesia medium discharge hole 33 in each anesthesia mechanism 30 discharges the anesthesia medium, that is, at least two anesthesia medium discharge holes 33 respectively send the anesthesia medium to the working surfaces of each single board 21. Of course, in specific implementation, the air inlet connectors 41 on the two anesthesia mechanisms 30 can also be respectively connected to two anesthesia medium conveying pipes, or control valves can be installed on the two air outlet connectors 42 of the three-way joint 40 to respectively control the independent operation of the two anesthesia mechanisms 30, so as to avoid waste of the anesthesia medium when only the working surface on one single board 21 is required to work. The connection method of the rubber hoses can not only ensure the sealing performance between the connection ends of the rubber hoses and the air outlet connectors 42 and the air inlet joints 31 during the introduction of the medium, but also, due to the flexible material of the rubber hoses, will not hinder the rotational switching between the loading state and the working state of the two single boards 21.

[0042] On the above basis, the connection method between the chassis 10 and the support plate 20 is bolt connection, which is fixed stably and conveniently and quickly. Of course, in specific implementation, a form such as the plug-in and anti-rotation cooperation between the insertion block 12 in the chassis 10 and the loading platform can also be adopted.

[0043] Of course, for those skilled in the art, the present utility model is not limited to the details of the above-described exemplary embodiments, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
