Description

Technical Field

[0001] This application relates to the field of pet body fat detection technology, specifically to a pet body fat percentage measurement system. Background Technology

[0002] The Body Condition Scoring (BCS) method is used to scientifically assess a pet's obesity status in order to develop a reasonable health management plan. Current BCS scoring methods assess fat coverage of the ribs, spine, and pelvis by observing the pet's overall outline and palpating. However, these methods, particularly visual inspection and palpation, require a high level of veterinary expertise and extensive experience, and are subjective judgments, thus carrying a significant margin of error.

[0003] With the development of technology, bioelectrical impedance analysis (BIA) has been applied to pet body fat analysis. However, bioelectrical impedance values ​​are affected by a variety of factors and there are individual differences, resulting in low accuracy in assessing pet obesity. These factors include changes in body water (such as dehydration or water intake), changes in body temperature and room temperature, and differences in body size, age, and sex.

[0004] To address this, Chinese invention patent CN115153492A discloses a modular intelligent body fat scale with pet body shape detection function. Using a matrix grid electrode, it can determine the pet's body length by observing the position of the pet's paws. It employs machine vision recognition to replace manual BCS scoring of the pet's body fat, providing comprehensive body fat data. However, the measurement accuracy of the matrix grid electrode in this solution is not high, and the accuracy of the BCS scoring by machine vision is also low, resulting in low accuracy in assessing the pet's obesity status.

[0047] Body fat analysis of pets can help assess their obesity status, providing a comprehensive understanding of their health, preventing diseases, and optimizing their reproductive and athletic performance. For example, it can help determine if a pet is overweight or obese, preventing related diseases; detect metabolic problems such as diabetes and fatty liver early, and develop personalized diet and exercise plans for the pet accordingly.

[0048] This application provides a pet body fat percentage measurement system. It constructs a pet body fat percentage calculation model by using multiple sets of body shape data, electrical impedance data and body fat percentage data of different pet breeds. It automatically measures the pet's body shape data and electrical impedance data using a three-dimensional automatic measuring device and detection electrodes on a body fat scale. It then calculates the current pet's body fat percentage by combining the pet's characteristic data and the pet body fat percentage calculation model. The system is easy to use and has high accuracy.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0050] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0051] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.

[0052] like Figure 1 As shown, this utility model provides a pet body fat percentage measurement system, including a body fat scale 100, a main unit 200, and a body fat percentage calculation module. The body fat percentage calculation module includes a pet body fat percentage calculation model, which is constructed using multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds. When a pet stands on the body fat scale 100, the system automatically measures the pet's body shape data and electrical impedance data, and then automatically calculates the pet's body fat percentage using the pet body fat percentage calculation model. The main unit 200 includes an input device and a display screen. The input device is used to input the pet's characteristic data, and the display screen is used to display the pet's body fat percentage measurement results.

[0053] The pet's size data includes its body length, body width, shoulder height, and weight.

[0054] Pet characteristics, including pet ID, breed, and age, can be entered via an input device.

[0055] The pet's electrical impedance data can be obtained by measuring electrodes set on the body fat scale 100.

[0056] Specifically, the formula for calculating R in the pet body fat percentage calculation model is as follows:

[0057] R = a1 + a2 × shoulder height + a3 × age + a4 × electrical impedance + a5 × body width + a6 × BMI;

[0058] Where a1 is a constant, and a2, a3, a4, a5 and a6 are linear fitting parameters;

[0059] BMI = weight / body length 2 .

[0060] The units for shoulder height and body width are cm, the unit for age is years, the unit for electrical impedance is Ω, the unit for weight is kg, and the unit for body length is m.

[0061] The larger the amount of data collected, the more accurate the parameter values ​​of constant a1 and fitting parameters a2, a3, a4, a5, and a6, and the higher the accuracy of the pet body fat percentage calculation model R.

[0062] Based on multiple sets of experimental data from pet dogs, the calculation formula for the body fat percentage calculation model R of pet dogs is as follows:

[0063] R = -18.087 - 0.267 × shoulder height + 0.712 × age + 0.008 × electrical impedance + 1.235 × body width + 0.172 × BMI.

[0064] Therefore, based on the pet body fat percentage calculation model, the body fat percentage of the current breed of pet can be calculated using the measured body size data and electrical impedance data. The measurement results are fast, accurate, and easy to use.

[0065] In this invention, the body fat percentage calculation module can be installed on the body fat scale 100, the host computer 200, or in the cloud. The specific installation method can be determined according to the usage scenario. For example, the body fat percentage calculation module can be installed on the body fat scale 100. In this method, the body fat scale 100 measures the pet's body shape and electrical impedance data, directly calculates the pet's body fat percentage, and then transmits it to the host computer 200 for display. No software or application needs to be installed on the host computer 200, making it suitable for any situation and convenient to use. Another method is to install the body fat percentage calculation module on the host computer 200. The body fat scale 100 measures the pet's body shape and electrical impedance data, transmits it to the host computer 200, and the host computer 200 calculates and displays the pet's body fat percentage. Since the body fat percentage calculation module is implemented using an app, it can be installed on any host computer, effectively reducing the cost of body fat percentage calculations, and making updates and upgrades more convenient.

[0066] like Figure 2 As shown, the body fat scale 100 includes a base 10 and a pet three-dimensional measurement device, a bioelectrical impedance measurement electrode, and a weight measurement device disposed on the base 10. The pet three-dimensional measurement device is used to measure the pet's body width, body length, and shoulder height. The bioelectrical impedance measurement electrode is used to measure the pet's bioelectrical impedance. The weight measurement device is used to measure the pet's weight.

[0067] The pet 3D measurement device includes two body width measuring rulers 21, two body length measuring rulers 22, and one shoulder height measuring ruler 23. The body width measuring rulers 21, body length measuring rulers 22, and shoulder height measuring rulers 23 are made of soft materials to ensure the safety of the pet during measurement.

[0068] Specifically, the top surface of the base 10 has a longitudinal groove 11 and a transverse groove 12 arranged perpendicularly to each other, intersecting at the center of the base 10. Four metal plates are provided on the top surface of the base 10, arranged in a grid pattern relative to the longitudinal and transverse grooves. These metal plates constitute the detection electrodes for bioelectrical impedance measurement. When a pet stands on the metal plates, the pet's bioelectrical impedance can be measured. In a preferred embodiment, two metal plates, either side or front and back, are short-circuited to form two detection electrodes (positive and negative), which not only simplifies the design but also improves the accuracy of the measurement results.

[0069] Two body width measuring rulers 21 are respectively set in the longitudinal slide groove 11. The longitudinal slide groove 11 is equipped with a longitudinal slider. The longitudinal slider and the longitudinal slide groove 11 constitute a longitudinal displacement measuring device. The lower end of the body width measuring ruler 21 is rotatably set on the longitudinal slider. The longitudinal slider can move along the length direction of the longitudinal slide groove 11 to measure the body width of the pet.

[0070] Two body length measuring rulers 22 are respectively set in the transverse slide groove 12. A transverse slider is provided in the transverse slide groove 12. The transverse slider and the transverse slide groove 12 constitute a longitudinal displacement measuring device. The lower end of the body length measuring ruler 22 is rotatably set on the transverse slider. The transverse slider can move along the length direction of the transverse slide groove 12 to measure the body length of the pet.

[0071] When in use, the body width measuring ruler 21 and body length measuring ruler 22 can be rotated upwards and set perpendicular to the top surface of the base 10. At the same time, they can be moved along the longitudinal slide 11 and the transverse slide 12 respectively, and abut against the left and right sides and front and back sides of the pet, so as to measure the pet's body width and body length.

[0072] When not in use, the width measuring ruler 21 and length measuring ruler 22 can be rotated downwards to a horizontal position for concealment, i.e., hidden in the base, reducing space occupation and making them easy to store and move.

[0073] The shoulder height measuring ruler 23 includes a vertical rod 231 and a horizontal rod 232 set on the vertical rod 231. The horizontal rod 232 is slidably connected to the vertical groove on the inner side of the vertical rod 231 through a vertical slider. The vertical slider and the vertical groove constitute a vertical displacement measuring device. Thus, the horizontal rod 232 can be moved up and down along the vertical rod 231 and placed against the pet's shoulder to measure the pet's shoulder height.

[0074] In this invention, the crossbar 232 adopts a multi-bar pull-out structure. A vertical groove is provided within the vertical slide groove, the width of which is greater than the thickness of the crossbar 232. One end of the crossbar 232 is rotatably mounted on the vertical slider. Thus, the crossbar 232 can be rotated downwards to a vertical position for concealment, i.e., hidden within the vertical slide groove.

[0075] In one embodiment, the base 10 has a side groove 13 along its length. The side groove 13 is adapted to the upright 231. The lower end of the upright 231 is rotatably disposed at one end of the side groove 13. The upright 231 can be rotatably disposed in two states: vertical and horizontal. When rotated to the vertical state, it is used for shoulder height measurement. When rotated to the horizontal position, the upright 231 is opposite to the side groove 13. Pushing the upright 231 inward can hide the upright 231 in the side groove 13, thereby facilitating storage and transportation.

[0076] The combination relationship between the width measuring ruler 21 and the longitudinal slider is as follows: Figure 3 As shown, the lower end of the body width measuring ruler 21 is provided with measuring ruler rotating shafts on both sides. The longitudinal slider includes a connecting seat 31 and a slider body 32 disposed on the bottom surface of the connecting seat 31. The slider body 32 is slidably disposed in the longitudinal groove 11. The connecting seat 31 is provided with a U-shaped notch, and the measuring ruler rotating shaft is rotatably disposed in the U-shaped notch.

[0077] The concealed structure of the upright 231 can adopt the following structure:

[0078] like Figure 4 As shown, one end of the side groove 13 on the base 10 is provided with a shaft hole, and the lower end of the upright 231 is provided with an upright shaft 233. The upright shaft 233 is adapted to the shaft hole and inserted into the shaft hole for rotational engagement.

[0079] The bottom surface of the base 10 is provided with a strip groove 14, which is arranged along the axial direction of the shaft at the lower end of the upright 231. The end of the shaft 233 of the upright is provided with a limiting piece 234, which slides in the strip groove 14 to limit the position of the upright 231 when it is pulled out and retracted.

[0080] In this design, when not in use, the width measuring ruler 21, length measuring ruler 22, and shoulder height measuring ruler 23 can all rotate downwards and be hidden in the base 10, thus facilitating storage and transportation. Figure 5 As shown.

[0081] The base 10 contains a signal transmission unit for transmitting detection data to the processing host 200. The signal transmission unit can be connected to the host 200 via wired or wireless means.

[0082] exist Figure 6 In one usage scenario shown, the body fat scale 100 and the host 200 are connected wirelessly. The body fat percentage calculation module is integrated into the pet body fat measurement app, which is installed on a tablet or smart TV. After receiving the measurement data from the body fat scale 100, the pet body fat percentage is calculated using the body fat percentage calculation module and displayed on the display interface.

[0083] Each test result and data can be stored on the server. Users can log in to the server with a username and password and query the test results and history of the pet by the pet ID.

[0084] An RFID reader can be installed on the body fat scale 100 or the main unit 200 to identify and obtain the pet's characteristic data by reading the pet's tag, or biochip technology can be used for identification and reading.

[0085] When performing bioelectrical impedance measurements on pets, the standard requires the pet to stand on four metal plates on a base with each of its four paws on top. However, in practice, pets often move around or even lie down on the base, leading to inaccurate measurements or even making it impossible to obtain the pet's bioelectrical impedance. To avoid this problem, this application provides a pluggable and detachable belly support device 40 on the base 10 to restrict the pet's movement or lying down.

[0086] like Figure 7 , Figure 8 , Figure 9 As shown, the abdominal support device 40 includes an abdominal support 41 and a support rod 42, with the abdominal support 41 fixed to the upper end of the support rod 42.

[0087] The base 10 has a socket 15 at its center, and multiple pressure rods 16 are arranged in the socket 15 along the circumferential direction. A micro switch is set in the base 10 for each pressure rod. The pressure rod 16 is slidably arranged up and down and is opposite to the contact end of the micro switch. The corresponding micro switch can be opened or closed by moving the pressure rod 16 up and down.

[0088] A sleeve 17 is inserted and fixed inside the insertion hole 15. An axially arranged strip-shaped protrusion 171 is provided on the inner wall of the sleeve 17. A limiting groove 421 is provided on the lower end face of the tube wall of the support rod 42. The limiting groove 421 is adapted to the strip-shaped protrusion 171. The support rod 42 is inserted into the sleeve 17.

[0089] In this application, the support rod 42 adopts a circular tube structure and is adapted to the inner diameter of the sleeve 17. Multiple slots 422 are provided on the lower end surface of the tube wall of the support rod 42 along the circumferential direction. The position of each slot corresponds to the position of the pressure rod 16, and each slot has a first depth and a second depth. The first depth is greater than the height of the pressure rod 16, and the second depth is less than the height of the pressure rod 16, which is used to press down and close the corresponding micro switch.

[0090] Different models of abdominal support devices have different positions and numbers of slots with a second depth on the support rod 42. When the limiting groove 421 and the strip-shaped protrusion 171 are inserted and positioned, different slots press against different pressure rods, thereby closing different microswitches. Therefore, based on the combination of different microswitch closing states, the corresponding model of the abdominal support device can be determined. The weight of different models of abdominal support devices can be pre-input into the body fat percentage calculation module, so that when measuring the pet's weight, the skin can be removed for different models of abdominal support devices to obtain the pet's actual weight.

[0091] Figure 10 This is a schematic diagram illustrating the application of the abdominal support device.

[0092] The identification method of the abdominal support device will be described in detail below through an embodiment.

[0093] In this embodiment, the base 10 is provided with three micro switches A, B and C. The support rod 42 of the first type of abdominal support device has slots corresponding to the two micro switches A and B. The depth of the slots is less than the height of the pressure rod 16. When the first type of abdominal support device is inserted, micro switches A and B are closed and micro switch C is opened, generating signal 110.

[0094] The support rod 42 of the second-type abdominal support device has slots corresponding to two microswitches A and C. The depth of these slots is less than the height of the pressure rod 16. When the second-type abdominal support device is inserted, microswitches A and C close, microswitches B open, and signal 101 is generated.

[0095] The support rod 42 of the third-type abdominal support device has slots corresponding to the two microswitches B and C. The depth of these slots is less than the height of the pressure rod 16. When the third-type abdominal support device is inserted, microswitches B and C close, microswitches A open, and signal 011 is generated.

[0096] Therefore, when the three different models of abdominal support devices are inserted, the states of each microswitch and the corresponding abdominal support signals generated are as follows:

[0097] Abdominal support device model micro switch A micro switch B micro switch C Abdominal support signal First closure closure disconnect 110 second closure disconnect closure 101 third disconnect closure closure 011

[0098] The corresponding belly support device model can be obtained based on the received belly support signal (110, 101 or 011), and then the weight of the currently used belly support device can be obtained so that the weight of the belly support device can be removed when measuring the pet's weight to obtain the pet's actual weight.

[0099] The above embodiments are merely illustrative examples. Three, five, or more microswitches can be set according to actual needs to adapt to more models of abdominal support devices.

[0100] In addition, the support bar can be a pull-out lifting bar to accommodate pets of different heights.

[0101] The abdominal support device is made of insulating material to ensure the accuracy of bioelectrical impedance data during measurement.

[0102] Based on the above description of specific embodiments, the pet body fat percentage measurement system provided by the utility model has the following advantages compared with the prior art:

[0103] A pet body fat percentage calculation model is constructed using multiple sets of body shape data, electrical impedance data, and body fat percentage data from different pet breeds. By acquiring the current pet's body shape data and electrical impedance data, the pet body fat percentage calculation model is used to automatically calculate the current pet's body fat percentage. This method is fast, efficient, accurate, and easy to use.

[0104] Secondly, the body fat scale is equipped with a three-dimensional measurement device for pets, a bioelectrical impedance measurement device, and a weight measurement device. It automatically measures the current pet's body shape and electrical impedance data through two body width measuring rulers, two body length measuring rulers, and shoulder height measuring rulers that are set relatively by sliding. The measurement speed is fast and it is easy to use.

[0105] Third, the body width and body length measuring rulers in the pet 3D measuring device can be rotated downwards when not in use and hidden in the longitudinal and transverse sliding grooves on the top surface of the base, making them easy to store and move.

[0106] Fourth, the longitudinal slider, transverse slider, and vertical slider each have a certain friction with the groove wall of their respective grooves, allowing them to stop at any position for convenient measurement.

[0107] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0108] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
