Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and particularly to an animal chamber positioning device and a positioning method. Background Art

[0002] When performing magnetic resonance examinations on animals, it is necessary to align the part of the animal to be examined with the center of the low-temperature coil of the magnetic resonance device to make the detection results more accurate. Since there are many types of animals and the parts to be detected are different, before examining different animals and parts, it is necessary to adjust the position of the part of the animal to be detected so that the part of the animal to be detected is aligned with the center of the low-temperature coil. The traditional method of adjusting the animal chamber is to place the animal in the animal chamber and insert the detection device, and then adjust the relative position between the animal chamber and the detection device to align the part of the animal to be detected with the center of the low-temperature coil. However, since the detection device will block the line of sight after the animal chamber is inserted into the detection device, it is impossible to directly observe the relative distance between the part of the animal to be detected and the low-temperature coil during the adjustment process, which affects the adjustment accuracy. Summary of the Invention

[0003] In view of this, the present invention provides an animal chamber positioning device and a positioning method to solve the problem that the line of sight is blocked by the detection device when adjusting the distance between the part of the animal to be detected and the low-temperature coil, resulting in affecting the adjustment accuracy.

[0004] To achieve the above object, the technical solution for the present invention to solve the technical problem is to provide an animal chamber positioning device, including: an animal chamber for carrying the animal to be examined; an adjustment mechanism provided on the animal chamber; a simulation chamber which is a columnar body with a through hole provided inside, and the animal chamber controls the position of the animal chamber in the through hole through the adjustment mechanism.

[0005] Further, an observation hole is provided on the circumferential outer shell of the simulation chamber along the direction of the through hole, or the simulation chamber is made of a transparent material, and the position of the animal chamber in the simulation chamber can be observed through the observation hole or the transparent material.

[0006] Further, a center mark is provided on the simulation chamber to locate the position of the animal chamber in the simulation chamber.

[0007] Further, the adjustment mechanism includes an adjustment component and a plug-in component, one end of the plug-in component is fixedly connected to the adjustment component, and the other end abuts against the simulation chamber.

[0008] Further, the simulation chamber includes a simulation probe and a simulation lining, the simulation lining is sleeved on the simulation probe; the through hole is provided on the simulation probe; a plug-in slot is provided on the simulation lining, and the plug-in component is inserted into the plug-in slot to realize the abutment of the plug-in component against the simulation chamber.

[0009] Further, the adjusting assembly includes a connecting member, an adjusting screw rod and a fixing member. The fixing member is fixedly connected to the animal chamber. The adjusting screw rod is located between the fixing member and the connecting member, and is rotatably connected to the fixing member and in threaded cooperation with the connecting member. The plug-in member is connected to one end of the connecting member away from the fixing member. By rotating the adjusting screw rod, the connecting member drives the plug-in member to move.

[0010] Further, the fixing member is located at one end of the animal chamber close to the simulation chamber. The connecting member includes an adjusting plate and a connecting plate. A threaded hole adapted to the adjusting screw rod is formed in the adjusting plate, and the adjusting screw rod is in threaded cooperation with the threaded hole. The connecting plates are located at opposite ends of the adjusting plate and are connected to the adjusting plate. The plug-in member is connected to one end of the connecting plate away from the adjusting plate.

[0011] Further, a strip-shaped hole is formed in the plug-in member, and a positioning hole is formed in the animal chamber. The strip-shaped hole communicates with the positioning hole. By inserting a screw or a pin into the positioning hole and clamping the plug-in member, the plug-in member is fixed.

[0012] Further, a sliding groove is formed in the animal chamber, and the plug-in member is in sliding cooperation with the sliding groove so that when the distance between the plug-in member and the animal chamber is adjusted by the adjusting assembly, the plug-in member slides in the sliding groove.

[0013] A method for positioning an animal chamber is completed by using an animal chamber positioning device. The method includes: pushing the animal chamber carrying the animal to be inspected into the simulation chamber, adjusting the adjusting mechanism on the animal chamber so that the area to be detected of the animal to be inspected is located at the center position of the simulation chamber, and locking the adjusting structure; taking out the animal chamber from the simulation chamber and directly pushing it into the detection device to complete the positioning of the animal chamber.

[0014] Compared with the prior art, the animal chamber positioning device provided by the present invention has the following beneficial effects:

[0015] Before detecting the animal, the animal chamber is pre-positioned in the simulation chamber with the simulation chamber as a reference. The part of the animal on the animal chamber to be detected is adjusted into the simulation chamber through the adjusting mechanism, and the position of the plug-in member on the animal chamber is fixed. Thus, during detection, only by sending the pre-positioned animal chamber into the detection device, the part of the animal in the animal chamber to be detected can be aligned with the coil center of the detection device, avoiding the problem that the line of sight is blocked by the detection device and it is inconvenient to adjust when adjusting the distance during the detection process.

[0016] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Please refer to Figure 1-6 , an animal cage positioning device 10 provided by the present invention includes an animal cage 20, an adjusting mechanism 30 and a simulation cage 40. The animal cage 20 houses the animal to be detected. The adjusting mechanism 30 is located between the animal cage 20 and the simulation cage 40, is disposed on the animal cage 20 and is connected to the animal cage 20. The simulation cage 40 is a columnar body, and a through hole 41 matching the animal cage 20 is provided inside it. The position of the animal cage 20 in the through hole 41 is controlled by the adjusting mechanism 30.

[0027] Specifically, by cooperating the adjusting mechanism 30 with the simulation chamber 40, and then adjusting the relative distance between the animal chamber 20 and the simulation chamber 40 after they are inserted into each other, when the animal chamber 20 and the adjusting mechanism 30 are directly inserted into the detection device after being pulled out from the simulation chamber 40, the part of the animal to be detected in the animal chamber 20 is exactly aligned with the center of the low-temperature coil of the detection device. The simulation chamber 40 is used as a substitute for the detection device, so as to perform positioning and calibration with the simulation chamber 40 as a reference before inserting the animal chamber 20 and the adjusting mechanism 30 into the detection device, so that the line of sight will not be blocked by the detection device during the adjustment process.

[0028] Further, the adjusting mechanism 30 includes a plug-in part 31 and an adjusting component 32. The adjusting component 32 is located between the plug-in part 31 and the animal chamber 20, and is respectively connected to the plug-in part 31 and the animal chamber 20. The distance between the plug-in part 31 and the animal chamber 20 can be adjusted through the adjusting component 32. One end of the plug-in part 31 is fixedly connected to the adjusting component 32, and the other end abuts against the simulation chamber 40. After the plug-in part 31 abuts against the simulation chamber 40, with the simulation chamber 40 as a reference, the position of the animal chamber 20 in the through hole 41 can be adjusted through the adjusting component 32, so as to adjust the distance between the animal chamber 20 and the simulation chamber 40. After the adjustment is completed, the relative position between the plug-in part 31 and the animal chamber 20 is fixed. Thus, after the plug-in part 31 is pulled out from the simulation chamber 40 and inserted into the detection device, the part of the animal to be detected in the animal chamber 20 is just aligned with the coil center of the detection device.

[0029] It can be understood that the overall shape structure of the simulation chamber 40 can be a cylindrical or square columnar body. In this embodiment, the shape structure and size of the cavity of the simulation chamber 40 are the same as those of the actual detection device, but the simulation chamber 40 is different from the actual detection device in terms of local structure, material and other characteristics. By making the through hole 41 the same as the cavity of the actual detection device, the position of the animal chamber 20 in the through hole 41 can be adjusted by using the adjusting mechanism 30 with the through hole 41 as a reference, so as to complete the pre-positioning of the animal chamber 20. In some embodiments, the size of the simulation chamber can also be different from the shape structure and size of the actual detection device, as long as the position of the animal chamber 20 in the through hole 41 can be adjusted to realize the pre-positioning of the animal chamber 20.

[0030] Further, in order to facilitate observing the position of the animal chamber 20 in the simulation chamber 40, an observation hole can be provided on the cabin body of the simulation chamber 40. Through this observation hole, the position of the animal chamber 20 in the simulation chamber 40 can be seen. The simulation chamber 40 can also be made of a transparent material. Through the transparent material, the position of the animal chamber 20 in the simulation chamber 40 can also be easily observed, so as to have a directly observable field of view when adjusting the position of the animal chamber 20 in the through hole 41.

[0031] Furthermore, a micro camera can be installed inside the simulation chamber 40 to obtain the position of the animal chamber 20 in the simulation chamber 40 through this micro camera.

[0032] It can be understood that the detection device can be a magnetic resonance imaging device, a CT device, etc. for animal imaging monitoring, which have a relatively small detection aperture. Since the aperture of the device for animal imaging monitoring is small, after the animal is stuffed into the monitoring device, it is impossible to observe the specific position of the animal inside the device, so pre-positioning is required before putting the animal into the device.

[0033] It can be understood that after adjusting the distance between the animal chamber 20 and the simulation chamber 40, the relative position between the plug-in part 31 and the animal chamber 20 needs to be fixed to prevent the distance set with the simulation chamber 40 as a reference from being disrupted when the plug-in part 31 is inserted into the detection device, resulting in the misalignment between the part of the animal to be detected in the animal chamber 20 and the coil center of the detection device. The way to fix the relative position between the plug-in part 31 and the animal chamber 20 can be to restrict the adjustment component 32 to prevent the adjustment component 32 from driving the relative displacement between the plug-in part 31 and the animal chamber 20. It can also be to fixedly connect the plug-in part 31 and the animal chamber 20 to directly restrict the relative displacement between the plug-in part 31 and the animal chamber 20.

[0034] Further, the adjustment component 32 includes a connecting part 321, an adjustment screw rod 322 and a fixing part 323. The fixing part 323 is fixedly connected to the animal chamber 20. The adjustment screw rod 322 is located between the fixing part 323 and the connecting part 321, is rotatably connected to the fixing part 323, and is in threaded cooperation with the connecting part 321. The plug-in part 31 is connected to the side of the connecting part 321 away from the fixing part 323. By rotating the adjustment screw rod 322, the connecting part 321 can move in the direction of approaching or departing from the animal chamber 20 on the adjustment screw rod 322 through threaded transmission, and drive the plug-in part 31 to move together, so as to realize the adjustment of the distance between the plug-in part 31 and the animal chamber 20.

[0035] It should be noted that in some embodiments, the adjustment component 32 can be a cylinder or a hydraulic cylinder fixedly connected to the animal chamber. The push rod of the cylinder or the hydraulic cylinder is connected to the plug-in part 31, and the distance between the plug-in part 31 and the animal chamber 20 is adjusted by the telescopic movement of the push rod.

[0036] It can be understood that the rotational connection between the adjustment screw rod 322 and the fixing part 323 can be realized through shaft-hole cooperation or by setting bearings, as long as the adjustment screw rod 322 can rotate relative to the fixing part 323.

[0037] Further, the fixing part 323 is fixedly connected to one end of the animal chamber 20 close to the simulation chamber 40.

[0038] It can be understood that the dimension of the animal compartment 20 in the direction of being inserted into the simulation compartment 40 is the length of the animal compartment 20. The fixing member 323 is connected to one end of the animal compartment 20 close to the simulation compartment 40, that is, the fixing member 323 is located at a position between the midpoint of the length of the animal compartment 20 and the end point of the animal compartment 20 close to the simulation compartment 40. By arranging the fixing member 323 at the position of one end of the animal compartment 20 close to the simulation compartment 40, the lengths of the adjusting screw rod 322 and the connecting member 321 can be shortened.

[0039] Furthermore, the connecting member 321 includes an adjusting plate 324 and a connecting plate 325. The connecting plate 325 is located at opposite ends of the adjusting plate 324 and is connected to the adjusting plate 324. The plug-in member 31 is connected to one end of the connecting plate 325 away from the adjusting plate 324. A threaded hole 326 adapted to the adjusting screw rod 322 is formed in the adjusting plate 324, and the adjusting screw rod 322 is in threaded cooperation with the threaded hole 326. By rotating the adjusting screw rod 322, the adjusting plate 324 is moved on the adjusting screw rod 322, so as to drive the plug-in member 31 to move away from or close to the animal compartment 20 through the connecting plate 325.

[0040] Furthermore, a sliding groove 21 is formed in the animal compartment 20, and the plug-in member 31 is in sliding cooperation with the sliding groove 21. When the plug-in member 31 moves away from or close to the animal compartment 20, the plug-in member 31 slides in the sliding groove 21.

[0041] Furthermore, a strip-shaped hole 311 is formed in the plug-in member 31, and a positioning hole 22 is further formed in the animal compartment 20. The strip-shaped hole 311 communicates with the positioning hole 22. After the distance between the plug-in member 31 and the animal compartment 20 is adjusted by the adjusting assembly 32, by inserting a screw or a pin into the positioning hole 22, and using the screw to be in threaded cooperation with the positioning hole 22 or the pin to be inserted into the positioning hole and clamping the plug-in member 31, the plug-in member 31 is fixed. This avoids the adjusted distance being disrupted during the process of pulling the plug-in member 31 out of the simulation compartment 40 and inserting it into the detection device after the distance between the plug-in member 31 and the animal compartment 20 is adjusted.

[0042] Furthermore, the fixing member 323 is fixedly connected to the animal compartment 20 by screws.

[0043] It can be understood that in this embodiment, the adjusting assembly 32 is directly connected to the surface of the animal compartment 20. In some embodiments, the adjusting assembly 32 can also be arranged inside the animal compartment 20 or other parts, as long as it can adjust the distance between the plug-in member 31 and the animal compartment 20 based on the simulation compartment, so that when the animal in the animal compartment is detected by the detection device, the part to be detected is aligned with the center of the coil of the detection device.

[0044] Please refer to Figure 7, the simulation chamber 40 includes a simulation probe 42 and a simulation inner lining 43. The simulation inner lining 43 is sleeved on the simulation probe 42. A through hole 41 is formed in the simulation probe 42. After the adjustment mechanism 30 is cooperated with the simulation chamber 40, the position of the animal chamber 20 in the through hole 41 is adjusted by the adjustment mechanism 30, so that when the animal to be detected in the animal chamber 20 enters the detection device, it is just aligned with the coil center of the detection device.

[0045] Specifically, a plugging groove 431 is formed in the simulation inner lining 43. The plugging member 31 is in plugging fit with the plugging groove 431. A center mark (not shown in the figure) is provided in the simulation probe 42. The center mark is used as a reference for the position of the animal chamber 20 in the through hole 41. For example, after the plugging member 31 is in plugging fit with the plugging groove 431, the distance between the animal chamber 20 and the plugging member 31 is adjusted by the adjustment component 32, that is, the position of the animal chamber 20 in the through hole 41 is adjusted until the part of the animal to be detected in the animal chamber 20 is aligned with the center mark. At this time, the plugging member 31 is pulled out from the plugging groove 431 and then inserted into the detection device, and the part of the animal to be detected in the animal chamber 20 is located at the coil center of the detection device.

[0046] It can be understood that in this embodiment, both the simulation probe 42 and the simulation inner lining 43 are made of transparent materials, and can be directly observed when the position of the animal chamber 20 in the through hole 41 is adjusted by the adjustment component 32, so that the part of the animal to be detected in the animal chamber 20 is aligned with the center mark.

[0047] It can be understood that in some embodiments, the center mark can be omitted, and the function of the center mark can be directly replaced by setting the length of the simulation probe 42. For example, after the plugging member 31 is inserted into the plugging groove 431, the part of the animal to be detected in the animal chamber is directly adjusted to be flush with the simulation probe 42, so that it can be aligned with the coil center of the detection device when being detected.

[0048] It can be understood that in some embodiments, when the center mark is omitted, the position of the animal chamber 20 in the through hole 41 can also be adjusted by the experience of the personnel.

[0049] It can be understood that in some embodiments, the plugging groove 431 can also be omitted, and the plugging member 31 is directly abutted against one end face of the simulation chamber 40 close to the plugging member 31, and then the position of the animal chamber 20 in the through hole 41 is adjusted by the adjustment mechanism 30, so that when the animal chamber 20 is taken out from the through hole 41 and inserted into the detection device, the animal to be detected in the animal chamber 20 is just aligned with the coil center in the detection device.

[0050] The animal chamber positioning method is completed by using an animal chamber positioning device. The method includes: pushing the animal chamber 20 carrying the animal to be examined into the simulation chamber 40, adjusting the adjusting mechanism 30 on the animal chamber 20 so that the area to be detected of the animal to be examined is located at the central position of the simulation chamber 40, and locking the adjusting structure 30; taking out the animal chamber 20 from the simulation chamber 40 and directly pushing it into the detection device to complete the positioning of the animal chamber 20.

[0051] Specifically, when magnetic resonance detection needs to be performed on an animal, first place and fix the animal in the animal chamber 20, and then insert the animal chamber 20 and the adjusting mechanism 30 into the simulation chamber 40, where the plug-in part 31 is in plug-in fit with the plug-in slot 431 to fix the position of the plug-in part 31. Then, adjust the distance between the animal chamber 20 and the plug-in part 31 through the adjusting component 32, so that the animal chamber 20 moves in the through hole 41 until the part of the animal in the animal chamber 20 to be detected is aligned with the position of the central mark on the simulation probe 42, that is, stop adjusting the distance, and fix the position between the plug-in part 31 and the animal chamber 20. After fixing the position between the plug-in part 31 and the animal chamber 20, pull out the plug-in part 31 from the plug-in slot 431, and finally send the plug-in part 31 and the animal chamber 20 into the detection device together. Since the distance between the plug-in part 31 and the animal chamber 20 has been fixed, after being inserted into the detection device, the part of the animal in the animal chamber 20 to be detected is just aligned with the center of the coil of the detection device, and no further adjustment is required.

[0052] Compared with the prior art, the animal chamber positioning device provided by the present invention has the following beneficial effects:

[0053] Before detecting an animal, first pre-position the animal chamber in the simulation chamber with the simulation chamber as a reference, adjust the part of the animal to be detected on the animal chamber into the simulation chamber through the adjusting mechanism, and fix the position of the plug-in part on the animal chamber. Thus, during detection, only need to send the pre-positioned animal chamber into the detection device, and the part of the animal in the animal chamber to be detected can be aligned with the center of the coil of the detection device, avoiding the problem that the line of sight is blocked by the detection device and it is inconvenient to adjust when adjusting the distance during the detection process.

[0054] By using a transparent material for the simulation chamber or providing an observation hole on the surface of the simulation chamber, it is very easy to observe the position of the animal chamber in the simulation chamber during the pre-positioning process.

[0055] By setting a central mark, when pre-positioning the animal chamber, the animal chamber can be aligned with the central mark to quickly find the positioning reference.

[0056] By setting the position of the fixing part at one end of the animal chamber close to the simulation chamber, the length of the adjusting screw rod and the connecting part can be reduced.

[0057] The specific embodiments of the present invention described above do not limit the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
