Description

Technical Field

[0001] The present invention relates to a body composition analyzer, in particular to a portable small animal body composition analyzer, and belongs to the technical field of small animal body composition detection. Background Art

[0002] The Small Animal Body Composition Analyzer is an analytical instrument used in the field of biology. It uses bioelectrical impedance analysis (BIA) to rapidly measure body composition information, including overall fat content and muscle tissue content, in living mice. This method is non-invasive and simple to operate. It applies a small, multi-frequency current to the animal through electrodes placed on its limbs. The resulting electrical impedance and its changes are detected.

[0003] When using a small animal body composition analyzer to measure mice, medical tape is usually used to fix the mice's limbs. If a large number of mice need to be measured, the staff must repeatedly tear off the medical tape, which is time-consuming and labor-intensive, increasing the staff's labor intensity. As a result, this fixation method cannot meet the needs of rapid measurement and also affects the measurement efficiency. Summary of the Invention

[0016] The beneficial effects of the present invention are:

[0017] 1. In this invention, when it is necessary to fix the limbs of a mouse on four first electrodes to measure the body composition information of the mouse, a fixing mechanism is provided on the front of the analyzer body, and a drive mechanism preset inside the analyzer body drives the two first electric telescopic rods to rotate, so that the two first electric telescopic rods can drive the connecting rods at their extended ends to wrap and reel up the two fixing belts, thereby pressing and fixing the limbs of the mouse located above the four first electrodes. This is convenient and fast and can be applied to measuring large quantities of mice.

[0018] 2.

[0019] 3. In this invention, since the physical conditions of the mice to be measured are different, some mice will secrete too much urine after being anesthetized. After the staff places the mice on the front of the analyzer body for measurement, the urine of the mice will drip onto the surface of the analyzer body, causing contamination to the analyzer body. After the work is completed, the mounting plate of the limiting mechanism can be placed on the front of the analyzer body, and the first electric slider and rotating frame provided on both sides of the analyzer body can be used to drive the cleaning pad provided on the mounting plate and its outer wall to wipe the urine of the mice on the surface of the analyzer body, so as to facilitate the subsequent use of the analyzer body.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Reference Figures 1-10 A portable small animal body composition analyzer includes an analyzer body 1, two groups of first slide grooves are opened on the front of the analyzer body 1, and first electrodes 4 are slidably installed in the two groups of first slide grooves. The outer wall of the first electrode 4 away from the analyzer body 1 is installed with a fixing mechanism for quickly fixing the limbs of the mouse. The fixing mechanism includes two fixing belts 6 installed at the bottom of the analyzer body 1, and multiple first electrodes 4 are installed with fixing rods 12 on the outer wall of the side away from the analyzer body 1. The ends of the two fixing belts 6 away from the bottom of the analyzer body 1 pass through multiple fixing rods 12 close to them. The top of the analyzer body 1 is installed with a limiting mechanism for limiting the mouse body.

[0034] As a technical optimization solution of the present invention, two movable blocks 13 are slidably mounted on the bottom of the analyzer body 1. A connecting plate 14 is mounted on the outer wall of each movable block 13 on the side away from the analyzer body 1. A through slot 15 is defined on the end of each of the two fixing straps 6, which is adjacent to the two movable blocks 13. Each of the two fixing straps 6 is detachably connected to the connecting plate 14 of the movable block 13 via the through slot 15 provided at one end, allowing the two fixing straps 6 to be removed for replacement or cleaning after extended use.

[0035] As a technical optimization solution of the present invention, the limiting mechanism includes a mounting plate 20 arranged on the top of the analyzer body 1, two limiting plates 8 are slidably installed on the bottom of the mounting plate 20, and a double-headed screw 23 is rotatably installed at the center position of the bottom of the mounting plate 20, and the two ends of the double-headed screw 23 respectively pass through the limiting plates 8 close to it.

[0036] As a technical optimization solution of the present invention, a movable plate 24 is slidably installed at the bottom of the two limit plates 8, and a connecting groove 25 is provided at one end of the two movable plates 24 located outside the limit plates 8. A connecting block 11 that matches the two connecting grooves 25 is installed on the top of the analyzer body 1. The two limit plates 8 can be connected and adapted to the connecting block 11 through the connecting grooves 25 at the bottom of the two movable plates 24, so that the two limit plates 8 and the mounting plate 20 can be installed on the top of the analyzer body 1. The outer wall of the two limit plates 8 on the side away from each other is rotatably installed with a first electric telescopic rod 21, and the two first electric telescopic rods 21 are installed with a connecting rod 26 at one end away from the limit plates 8. The ends of the two fixing belts 6 away from the movable block 13 are respectively connected to the connecting rod 26 close to it, and the ends of the two connecting rods 26 away from the first electric telescopic rod 21 are installed with a connecting column 22. When using the analyzer body 1 to measure a mouse, after placing the mouse on the analyzer body 1, the mouse's limbs are placed on top of the four first electrodes 4 respectively. The two first electric telescopic rods 21 are driven to rotate synchronously by the preset driving mechanism inside the analyzer body 1, thereby driving the two connecting rods 26 to wind up the two fixing belts 6. Since the two fixing belts 6 are made of rubber material, during the process of the two connecting rods 26 winding up the fixing belts 6, the two fixing belts 6 will be driven to fit tightly with the outer walls of the two groups of first electrodes 4, thereby automatically pressing the mouse's limbs. The two fixing belts 6 are fixed to facilitate the measurement of the body information of the mouse; and one end of the two fixing belts 6 is respectively connected to the two connecting rods 26, and the other end is respectively connected to the two moving blocks 13. When the two first electric telescopic rods 21 drive the connecting rods 26 to retract, the two fixing belts 6, the two groups of first electrodes 4 and the two moving blocks 13 can be synchronously driven to move toward each other, and the distance between the two groups of first electrodes 4 can be adjusted, which is convenient for measuring mice of different sizes; and for mice with different limb lengths, the distance between the two groups of first electrodes 4 can also be adjusted to facilitate their measurement.

[0037] As a technical optimization solution of the present invention, grooves are provided on the tops of multiple first electrodes 4, and second electrodes 28 are installed in multiple grooves. Multiple second electric telescopic rods 27 are installed inside the analyzer body 1, and the extended ends of the multiple second electric telescopic rods 27 pass through the first electrodes 4 close to them and are connected to the second electrodes 28. Pressure sensors 29 are installed at the bottoms of the multiple second electrodes 28. When the two fixing straps 6 press and fix the mouse's limbs, due to the different fatness of the mouse's limbs, the mouse's limbs may not be in close contact with the second electrode 28, resulting in inaccurate measurement results. To avoid this, when the mouse's limbs are placed on top of the second electrode 28, they will press the second electrode 28, allowing the pressure sensor 29 to sense the pressure of the mouse's limbs in real time. For example, after the two fixing straps 6 press and fix the mouse's limbs, no value is displayed on the display screen 2 of the analyzer body 1. At this time, the pressure sensor 29 will transmit a signal to the controller preset in the analyzer body 1, which will drive the extended end of the second electric telescopic rod 27 to extend upward, thereby pushing one or more mouse limbs that are not in close contact with the second electrode 28 and the fixing strap 6 to move upward, so that the mouse limbs are in close contact with the top of the second electrode 28 and the bottom of the fixing strap 6, improving the accuracy of the measurement data. The pressure sensor 29 is a DJWX-20C high-precision micro pressure sensor in the prior art.

[0038] As a technical optimization solution of the present invention, a cleaning pad 9 is detachably mounted on the top of the mounting plate 20 , and the cleaning pad 9 is a sponge pad.

[0039] As a technical optimization solution of the present invention, a start button 3 is provided on the front of the analyzer body 1 above the plurality of first electrodes 4. A display screen 2 is provided above the start button 3. A cleaning pad 9 provided on top of the mounting plate 20 cleans the surface of the analyzer body 1 after use, making it easier to use the analyzer body 1 the next time.

[0040] As a technical optimization solution of the present invention, second slide grooves 10 are provided on two opposite sides of the analyzer body 1 , and first electric sliders 16 are installed in the two second slide grooves 10 .

[0041] As a technical optimization solution of the present invention, the outer walls of the two first electric sliders 16 away from the second slide groove 10 are both rotatably mounted with a rotating frame 5, and two second electric sliders 18 are installed inside the two rotating frames 5.

[0042] As a technical optimization solution of the present invention, a movable plate 17 is commonly installed on the outer wall of the side where the two second electric sliders 18 are close to each other, and an electric clamp 19 for clamping and fixing the connecting column 22 is installed on the top of the movable plate 17. When the analyzer body 1 is used to measure the last few mice, the limiting mechanism originally located on the top of the analyzer body 1 can be moved to the position between the four first electrodes 4. At this time, the two connecting columns 22 are respectively clamped and fixed in the two electric clamps 19, thereby limiting the limiting mechanism as a whole. Then, the two limiting plates 8 are driven by the rotation of the double-headed screw 23 to limit the body of the mouse, thereby preventing the last few mice from waking up prematurely during measurement, which will affect the measurement work.

[0043] In the present invention, before measuring the mouse, the mouse needs to be fasted for more than 6 hours and then anesthetized. After the mouse completely loses consciousness, the mouse is placed on the analyzer body 1, and its limbs are placed on the top of the four first electrodes 4 respectively. The two first electric telescopic rods 21 are driven to rotate synchronously by the preset driving mechanism inside the analyzer body 1, and then the two connecting rods 26 can be driven to wind up the two fixing belts 6, driving the two fixing belts 6 to fit tightly with the outer walls of the two groups of first electrodes 4, so as to automatically press and fix the mouse's limbs. After using the two fixing belts 6 to press and fix the mouse's limbs, the start button 3 is turned on, so that the analyzer body 1 is turned on to detect the mouse. The results are displayed on the display screen 2 after about 10 seconds. The staff records the results and starts to detect the next one.

[0044] When using the analyzer body 1 to measure a large number of mice, due to the large number of mice and the fact that the mice are anesthetized at the same time, when measuring the last few mice, the double-headed screw 23 can be driven to rotate by the preset driving machine inside the analyzer body 1, driving the two limit plates 8 and the movable plates 24 at the bottom thereof to move in opposite directions until the connecting grooves 25 at the bottom of the two movable plates 24 are disengaged from the connecting block 11. The staff can then move the mounting plate 20 and the two limit plates 8 at its bottom to a position between the four first electrodes 4, control the two first electric sliders 16 to move in the second slide groove 10 to a position in the same straight line with the two limit plates 8, control the two rotating frames 5 to rotate upward to a vertical state, and control the two second electric sliders 18 in the two rotating frames 5 to move to a position flush with the two first electric telescopic rods 21, so that the connecting column 22 at one end of the two connecting rods 26 away from each other is located in the two electric clamps 19, and the two connecting columns 22 are clamped and fixed by the two electric clamps 19. , and then the positions of the mounting plate 20 and the two limiting plates 8 located on the front of the analyzer body 1 can be limited and fixed, and the last few mice can be placed between the two limiting plates 8 respectively. The two limiting plates 8 can be driven by the double-headed screw 23 to move in the direction of approaching each other to clamp and fix the mice, thereby preventing the last few mice from waking up prematurely during measurement and affecting the measurement work; and because the bottoms of the two limiting plates 8 are both equipped with movable plates 24, when the two limiting plates 8 are located on the front of the analyzer body 1, the bottom ends of the two movable plates 24 are in contact with the front of the analyzer body 1, and the second electric slider 18 can be controlled to move upward or downward in the rotating frame 5 according to the size of different mice, so as to change the length of the movable plate 24, which is convenient for fixing mice of different sizes. At the same time, the two first electric sliders 16 can be used to move in the second slide groove 10 to drive the two limiting plates 8 to move on the analyzer body 1, so that the two limiting plates 8 can clamp and fix mice of different lengths.

[0045] Because the physical conditions of the mice to be measured are different, some mice will secrete too much urine after being anesthetized. After the staff places the mice on the front of the analyzer body 1 for measurement, the mouse's urine will drip onto the surface of the analyzer body 1, and there will be a small amount of mouse hair or other debris on the surface of the analyzer body 1. These debris will cause pollution to the analyzer body 1. After the work of the analyzer body 1 is completed, the mounting plate 20 and the two limit plates 8 originally located on the top of the analyzer body 1 can be removed, and the top of the mounting plate 20 is driven by the side of the cleaning pad 9 and placed on the front of the analyzer body 1. The two first electric sliders 16 are synchronously controlled to drive the rotating frame 5 and the electric clamp 19 inside it to move to a position in the same straight line with the mounting plate 20. After the connecting columns 22 at both ends of the two limit plates 8 cooperate with the two electric clamps 19, the two first electric sliders 16 can be moved from one end of the second slide 10 to the other end, and the mounting plate 20 and the cleaning pad 9 can be synchronously driven to move on the front of the analyzer body 1, so that the front of the analyzer body 1 can be cleaned, which is convenient for the next use of the analyzer body 1.

[0046] At the same time, when the cleaning pad 9 is used to clean the front of the analyzer body 1, the mouse urine will accumulate in the first chute. Directly driving the cleaning pad 9 to move back and forth on the front of the analyzer body 1 by the two first electric sliders 16 cannot clean the mouse urine in the first chute. At this time, the two first electric sliders 16 can drive the mounting plate 20 and the cleaning pad 9 to move to the top of the first chute, and then the two second electric sliders 18 can drive the moving plate 17 and the electric clamp 19 on the top to move downward together, thereby driving the mounting plate 20 and the cleaning pad 9 moves downward together to squeeze the cleaning pad 9. Since the cleaning pad 9 is made of sponge, after being squeezed and deformed, the deformed part of the cleaning pad 9 can extend into the first chute to absorb the mouse urine in the first chute, thereby further improving the cleaning effect of the analyzer body 1; and after cleaning the analyzer body 1, the cleaning pad 9 adsorbed with mouse urine is removed and replaced with a clean cleaning pad 9, and then the mounting plate 20 can be controlled to stay above the display screen 2, so that the mounting plate 20 can protect the display screen 2 when the analyzer body 1 is not in use.

[0047] After using the analyzer body 1, press the start button 3 again to turn off the analyzer body 1. When it needs to be carried, the connection between the two fixing straps 6 and the moving block 13 can be released, and the ends of the two fixing straps 6 that have been removed can be connected, so that the two fixing straps 6 can now be used as hanging straps, which makes it convenient for the staff to use the hanging straps to carry the analyzer body 1 across the body or hang it around the neck for transportation, so that the analyzer body 1 is easy to carry.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the content of this specification.
