[0007] In some embodiments, the push rod includes a slide rail, and the positioning bracket is provided with a slider that cooperates with the slide rail.

[0008] In some specific embodiments, the push rod also includes a first fixed seat and a second fixed seat, the first fixed seat and the second fixed seat are respectively connected to the two ends of the slide rail through fixing screws, the first fixed seat is connected to the cabin body, and the second fixed seat is provided with a fixing through hole that cooperates with the cable.

[0009] In some embodiments, the locking structure includes a locking protrusion provided on the cabin body and a locking box provided on the positioning bracket; wherein: the locking protrusion can be inserted into the locking box to cooperate with the cabin body to lock the cabin body in the second working position; pressing the cabin body in the second working position can cause the locking box to release the locking protrusion, so that the cabin body and the push rod return to the first working position under the pull of the cable.

[0010] In some embodiments, a guide groove is provided on the positioning bracket, and the guide groove cooperates with the cable to guide the movement direction of the cable.

[0011] In some specific embodiments, the guide groove includes a first groove, a second groove and a third groove connected in sequence, the first groove and the third groove extend along the length direction of the positioning bracket and are respectively located on the top wall and the bottom wall of the positioning bracket, the second groove is an arc groove and is formed at the first end of the positioning bracket, and the cable is matched with the guide groove.

[0012] In some embodiments, one end of the cabin body connected to the push rod has an anesthetic gas inlet and an anesthetic gas outlet, and the positioning bracket is provided with a docking seat, and the docking seat has an inlet channel and an outlet channel; in the second working position, the docking seat is fitted with the cabin body so that the inlet channel docks with the anesthetic gas inlet, and the outlet channel docks with the anesthetic gas outlet.

[0013] In some specific embodiments, the docking seat is provided with a first elastic compression conduit and a second elastic compression conduit, and the first elastic compression conduit and the second elastic compression conduit are respectively arranged corresponding to the inlet channel and the outlet channel; wherein: in the second working position, the first elastic compression conduit is compressed and docked with the anesthetic gas inlet, and the second elastic compression conduit is compressed and docked with the anesthetic gas outlet.

At the same time, when the cabin body moves from the first working position to the second working position, the length of the cable extended from the cable box becomes longer, and the cable has a tendency to retract into the cable box, but due to the locking of the locking structure, the cable cannot be reeled in at this time. After the imaging is completed, the locking structure can be unlocked by pushing or pulling the cabin body again, and the cable can be reeled in at this time, and when reeled in, it can drive the cabin body back to the first working position. There is no need for the operator to laboriously and time-consumingly pull out the detection cabin module from the detection cavity as in the prior art, and the cabin body can be easily ejected from the detection cavity after the imaging is completed, which is convenient for the operator to operate and improves the user satisfaction.

[0017] The beneficial effects of the animal imaging device of the embodiment of the present invention are as follows: Since it has the detection chamber module described above, during the imaging process, the chamber body constitutes a cantilever structure supported by a push rod, which can ensure that the chamber body is stably maintained in the detection chamber and no other supporting structures exist in the detection chamber, thereby avoiding the phenomenon in the prior art that the supporting structure interferes with the imaging quality and imaging accuracy; and the chamber body can be easily popped out of the detection chamber after the imaging is completed, which is convenient for the operator to operate and improves user satisfaction.

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the description of this embodiment, the terms "upper", "lower", "left", "right", "front", "rear" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] refer to Figure 1-Figure 7 The specific structure of the detection chamber module of a specific embodiment of the present invention is described.

[0038] The present invention discloses a detection chamber module, referring to Figure 1 As shown, the detection chamber module of this embodiment includes a positioning bracket 100, a push rod 200, a chamber body 300 and a cable box 400. The positioning bracket 100 is fixed to the frame 10 of the animal imaging device. One end of the push rod 200 passes through the detection cavity of the animal imaging device and is slidably matched with the first end of the positioning bracket 100 along its length direction. The chamber body 300 is connected to the other end of the push rod 200 and is used to hold the animal to be imaged. The cable box 400 has a retractable cable 410. The free end of the cable 410 bypasses the second end of the positioning bracket 100 and is connected to the push rod 200. The chamber body 300 has a first working position (reference Figure 2 and Figure 4 shown) and the second working position (reference Figure 6 As shown), in the first working position, the cabin body 300 is located outside the detection cavity of the animal imaging device; in the second working position, the cabin body 300 is located inside the detection cavity and is locked on the positioning bracket 100 by a locking structure; in the first working position, pushing the cabin body 300 can move it to the second working position and lengthen the cable 410 to extend the length of the cable box 400; in the second working position, the cable 410 is reeled in to drive the cabin body 300 back to the first working position.

[0039] It can be understood that, in the actual working process, the initial position of the cabin body 300 is the first working position. In the first working position, the operator can fix the animal to be imaged (such as a mouse) inside the cabin body 300, and then push the cabin body 300 to move from the first working position to the second working position. Since the cabin body 300 of this embodiment is connected to a push rod 200, the push rod 200 and the positioning bracket 100 can be slidably matched. During the movement of the cabin body 300, the push rod 200 will move together. When the cabin body 300 moves to the second working position, the entire cabin body 300 constitutes a cantilever structure supported by the push rod 200, which can ensure that the cabin body 300 is stably maintained in the detection cavity, and there is no other supporting structure in the detection cavity, thereby avoiding the phenomenon that the supporting structure in the prior art interferes with the imaging quality and imaging accuracy. At the same time, when the cabin body 300 moves from the first working position to the second working position, the length of the cable 410 extended from the cable box 400 becomes longer, and the cable 410 has a movement tendency to retract the cable box 400, but due to the locking of the locking structure, the cable 410 cannot be reeled at this time. After the imaging is completed, the locking structure can be unlocked by pushing or pulling the cabin body 300 again, and the cable 410 can be reeled at this time, and when reeled, it can drive the cabin body 300 back to the first working position. There is no need for the operator to pull out the detection cabin module from the detection cavity with more effort and time as in the prior art, and the cabin body 300 can be more conveniently ejected from the detection cavity after the imaging is completed, which is convenient for the operator to operate and improves the user satisfaction.

[0040] It should be supplemented that the cable box 400 is a standard structure commonly used in the prior art and can be directly purchased according to actual needs. The specific structure of the cable box 400 is not limited here.

[0041] refer to Figure 3 As shown, the push rod 200 includes a slide rail 210, and the positioning bracket 100 is provided with a slider 120 that cooperates with the slide rail 210. It is understandable that the operator can fix the animal to be imaged (such as a mouse) inside the cabin body 300, and then in the process of pushing the cabin body 300 from the first working position to the second working position, the slide rail 210 can guide the movement direction of the slide rail 210, so as to avoid the push rod 200 from being skewed during the actual operation, resulting in the cabin body 300 being stuck inside the detection cavity. Of course, in an alternative embodiment of the present invention, the positioning bracket 100 can also be provided with a guide groove 130 that cooperates with the push rod 200, and the structure that guides the push rod 200 can be adjusted according to actual needs.

[0042] Optional, reference Figure 5-Figure 6As shown, the push rod 200 further includes a first fixing seat 220 and a second fixing seat 230, the first fixing seat 220 and the second fixing seat 230 are respectively connected to the two ends of the slide rail 210 by fixing screws, the first fixing seat 220 is connected to the cabin body 300, and the second fixing seat 230 is provided with a fixing through hole matched with the cable 410. It can be understood that under normal circumstances, a standard slide rail 210 is provided with a threaded hole, and the first fixing seat 220 and the second fixing seat 230 can stably support the slide rail 210, and avoid the need for secondary processing of the slide rail 210 when the slide rail 210 is directly connected to the cabin body 300 and the cable 410, so as to facilitate assembly.

[0043] Further optionally, the first fixing seat 220 is a fixing block, which is fixed to the cabin body 300 by screws. The first fixing seat 220 is provided with a fixing groove, and one end of the slide rail 210 is installed in the fixing groove and locked by a fixing screw.

[0044] Further optionally, the second fixing seat 230 is an L-shaped fixing seat, the horizontal plate of the L-shaped fixing seat is locked with the other end of the slide rail 210 by a fixing screw, and the vertical plate of the L-shaped fixing seat is provided with a fixing hole, in which a screw or pin or other structure for binding the cable 410 can be installed.

[0045] Of course, in other embodiments of the present invention, the slide rail 210 may also be directly fixed to the cabin body 300 and the cable 410 by welding or bonding, and is not limited to the above description.

[0046] refer to Figure 3 and Figure 5As shown, the locking structure includes a locking protrusion 310 provided on the cabin body 300 and a locking box 110 provided on the positioning bracket 100. The locking protrusion 310 can be inserted into the locking box 110 to lock the cabin body 300 in the second working position; wherein, pressing the cabin body 300 in the second working position can cause the locking box 110 to release the locking protrusion 310, so that the cabin body 300 and the push rod 200 return to the first working position under the pull of the cable 410. It can be understood that the operator can fix the animal to be imaged (such as a mouse) inside the cabin body 300, and then when the cabin body 300 is pushed from the first working position to the second working position, the locking protrusion 310 can be inserted into the locking box 110 to lock the cabin body 300 in the second working position, ensuring that the cabin body 300 can be stably maintained in the detection cavity during the entire imaging process, ensuring imaging accuracy and imaging quality. When imaging is completed, pressing the cabin body 300 in the second working position can release the locking protrusion 310 of the lock box 110, and the cable 410 is wound under the action of the coil spring inside the cable box 400, so that the cabin body 300 and the push rod 200 return to the first working position under the pull of the cable 410. The locking structure includes the locking protrusion 310 and the lock box 110, and realizes the functions of plug-in locking and press-to-unlock, so that the structure of locking the cabin body 300 and releasing the cabin body 300 is very convenient, which further facilitates user operation and improves user experience.

[0047] It should be noted that the lock box 110 is a standard structure commonly used in the prior art and can be purchased directly according to actual needs. The specific structure of the lock box 110 is not limited here. In addition, in other embodiments of the present invention, the locking structure can also select other structures according to actual needs. For example, a magnetic suction piece is provided on the cabin body 300, and an electromagnet that cooperates with the magnetic suction piece is provided on the positioning bracket 100. After the imaging is completed, the cabin body 300 can be released by disconnecting the power of the electromagnet.

[0048] refer to Figure 7The positioning bracket 100 is provided with a guide groove 130, and the guide groove 130 cooperates with the cable 410 to guide the movement direction of the cable 410. It can be understood that, according to the above, after the imaging is completed, pressing the cabin body 300 in the second working position can make the lock box 110 release the locking protrusion 310, and the cable 410 is wound under the action of the coil spring inside the cable box 400, so that the cabin body 300 and the push rod 200 return to the first working position under the pulling of the cable 410. If the movement of the cable 410 is not constrained during the winding process of the cable 410, it is easy to cause the cable 410 to be skewed or even cause the cabin body 300 to be stuck. In this embodiment, a guide groove 130 for guiding the movement of the cable 410 is added to avoid the skew of the cable 410, thereby ensuring that the cabin body 300 can stably return to the first working position during the winding process of the cable 410.

[0049] Optionally, the guide groove 130 includes a first groove, a second groove and a third groove connected in sequence, the first groove and the third groove are extended along the length direction of the positioning bracket 100, and are respectively located on the top wall and the bottom wall of the positioning bracket 100, the second groove is an arc groove, and is formed at the first end of the positioning bracket 100, and the cable 410 is matched with the guide groove 130. It can be understood that the guide groove 130 is formed on the top wall, the bottom wall and the first end of the positioning bracket 100, so that the guide groove 130 is a U-shaped groove, and the notch of the U-shaped groove is set at the first end of the positioning bracket 100. The guide groove 130 of this shape can enhance the guiding effect on the cable 410, and reduce the friction between the cable 410 and the inside of the guide groove 130 to a certain extent, ensuring that the cabin body 300 can stably return to the first working position during the winding process of the cable 410 while reducing the wear of the cable 410.

[0050] refer to Figure 5-Figure 7As shown, one end of the cabin body 300 connected to the push rod 200 has an anesthetic gas inlet 320 and an anesthetic gas outlet 330, and a docking seat 500 is provided on the positioning bracket 100, and the docking seat 500 has an inlet channel and an outlet channel; in the second working position, the docking seat 500 is fitted with the cabin body 300 so that the inlet channel docks with the anesthetic gas inlet 320, and the outlet channel docks with the anesthetic gas outlet 330. It is understandable that during the imaging process, the animal to be imaged usually needs to be anesthetized. The operation of external anesthesia is relatively complicated and can easily injure the animal to be imaged. In this embodiment, when in the second working position, the docking seat 500 is fitted with the cabin body 300 so that the inlet channel docks with the anesthetic gas inlet 320 and the outlet channel docks with the anesthetic gas outlet 330. At this time, the external anesthetic gas source is connected to the inlet channel and the outlet channel of the docking seat 500, and the outlet valve of the external anesthetic gas source is opened. The anesthetic gas enters the inlet channel from the output port of the external anesthetic gas source through the trachea and then enters the cabin body 300 from the anesthetic gas inlet 320 to achieve anesthesia of the animal to be imaged. Then, the return valve of the external anesthetic gas source is opened, and the excess anesthetic gas can be discharged to the outlet channel through the anesthetic gas outlet 330 and finally return to the external anesthetic gas source through the trachea. Therefore, during the imaging process, the anesthesia of the animal to be imaged can be achieved by only opening the outlet valve and the return valve of the external anesthetic gas source, without the need for external anesthesia, and the operation is convenient and will not cause damage to the imaged animal.

[0051] Optionally, the docking seat 500 is provided with a first elastic compression conduit 510 and a second elastic compression conduit 520, and the first elastic compression conduit 510 and the second elastic compression conduit 520 are respectively arranged corresponding to the inlet channel and the outlet channel: in the second working position, the first elastic compression conduit 510 is compressed and docked with the anesthetic gas inlet 320, and the second elastic compression conduit 520 is compressed and docked with the anesthetic gas outlet 330. It can be understood that in the actual working process, the first elastic compression conduit 510 is compressed and docked with the anesthetic gas inlet 320, and the second elastic compression conduit 520 is compressed and docked with the anesthetic gas outlet 330. In the second working position, the anesthetic gas inlet 320, the first elastic compression conduit 510 and the inlet channel form a relatively closed flow channel. Similarly, the anesthetic gas outlet 330, the second elastic compression conduit 520 and the outlet channel form a relatively closed flow channel, which can better avoid the phenomenon of anesthetic gas leakage during the anesthesia of the animal to be imaged.

[0052] refer to Figure 6-Figure 7As shown, the detection cabin module also includes a third fixed seat 600, which is connected to the frame 10 and to the second end of the positioning bracket 100. It can be understood that the positioning bracket 100 is vertically arranged with the frame 10, and it is relatively difficult to connect directly. In this embodiment, a third fixed seat 600 is added, and the third fixed seat 600 includes a first vertical plate, a horizontal plate and a second vertical plate. The first vertical plate and the second vertical plate are integrally formed on two sides of the horizontal plate that are opposite to each other, and the second vertical plate is vertically arranged with the first vertical plate and the horizontal plate. The first vertical plate and the horizontal plate are connected to the frame 10 by screws, and the second vertical plate is connected to the second end of the positioning bracket 100 by screws, which is conducive to ensuring the connection stability of the positioning bracket 100, thereby indirectly ensuring the stability of the cabin body 300 and the push rod 200.

[0053] Optionally, the detection chamber module further includes a fourth fixing seat 700, which is connected to the third fixing seat 600 and is used to install the cable box 400. It can be understood that the fourth fixing seat 700 is formed as a sheet metal part, which can conveniently and firmly fix the cable box 400, ensure the stability of the cable box 400, and thus ensure that the cable 410 stably drives the chamber body 300 to reset.

[0054] The present invention also discloses an animal imaging device, including a frame 10, a detection module and the detection chamber module mentioned above, wherein the detection module has a detection chamber, and the chamber body 300 of the detection chamber module has a first working position located outside the detection chamber and a second working position located inside the detection chamber. Due to the detection chamber module mentioned above, during the imaging process, the chamber body 300 constitutes a cantilever structure supported by the push rod 200, which can ensure that the chamber body 300 is stably maintained in the detection chamber, and there is no other supporting structure in the detection chamber, thereby avoiding the phenomenon that the supporting structure in the prior art interferes with the imaging quality and imaging accuracy; and the chamber body 300 is more convenient to pop out of the detection chamber after the imaging is completed, which is convenient for the operator to operate and improves the user satisfaction.
