Description

Technical Field

[0001] The present invention relates to the technical field of waist measurement, and in particular to a medical intelligent waist measurement system and a measurement method. Background Art

[0002] Waist circumference is the circumference of the midpoint between the lowest point of the ribs and the upper edge of the iliac crest. It is a comprehensive indicator of total fat mass and fat distribution. Measuring waist circumference is important for assessing individual health status, especially health risks related to obesity.

[0003] In the current medical and health field, waist circumference is an important indicator for assessing human health, especially the risk of abdominal obesity and metabolic syndrome. The accuracy and convenience of its measurement have attracted much attention. Traditional waist circumference measurement tools use soft tape. Although low-cost and widely used, in actual use, traditional measurement methods have certain shortcomings. The measurement positioning is inaccurate, the measurement process is easily affected by human factors and causes errors, and the measurement plane cannot be automatically calibrated to maintain a horizontal state.

[0004] At present, with the development of electronic technology, electronic waist rulers have emerged. The integration of electronic technology has improved the degree of automation of measurement to a certain extent, but most products still rely on manual positioning, resulting in insufficient accuracy during the measurement process.

[0005] Therefore, we proposed a medical intelligent waist measurement system and measurement method. Summary of the Invention

[0006] The purpose of the present invention is to provide a medical intelligent waist measurement system and measurement method, which solves the problems raised in the background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a medical intelligent waist measurement system, comprising: a positioning module, a measurement module, a display and transmission module, a housing and a wearable module, and a control terminal;

[0008] The positioning module is used to automatically identify and lock the midpoint of the line connecting the iliac crest and the costal arch at the mid-axillary line as the waist circumference measurement point;

[0009] The measuring module is used to sense changes in waist size and ensure that the measuring plane is level;

[0010] The display and transmission module is used to display waist circumference data in real time and transmit the data;

[0011] The housing and the wearable module are used to assist in wearing the device and are tied around the waist of the person being measured;

[0012] The control center is used to process data and information and store data synchronously.

[0013] As a preferred embodiment of the present invention, the positioning module includes a bilateral infrared bone landmark scanning device and an adjustable robotic arm. The positioning error of the bilateral infrared bone landmark scanning device is ≤0.2 cm. The adjustable robotic arm is connected to the bilateral infrared bone landmark scanning device to adjust the horizontality of the bilateral infrared bone landmark scanning device.

[0014] As a preferred embodiment of the present invention, the measurement module includes a nanosilver flexible strain sensor and a three-axis MEMS level. The nanosilver flexible strain sensor is specifically a sensing belt with a measuring range of 60-150 cm.

[0015] As a preferred embodiment of the present invention, the accuracy of the three-axis MEMS level is 0.1°.

[0016] As a preferred embodiment of the present invention, the display and transmission module includes an OLED touch screen and a Bluetooth module, the OLED touch screen is used to display data, and the Bluetooth module is used to transmit data.

[0017] As a preferred embodiment of the present invention, the shell and wearable module include a shell and a wearable structure. The skin-contacting parts of the shell and the wearable structure are both made of medical-grade silicone material. The wearable structure includes a belt body and a magnetic buckle fixed on the belt body.

[0018] As a preferred embodiment of the present invention, the control center further includes a storage module and an alarm module. The storage module is used to store data, and the alarm module is used to sound an alarm.

[0019] The present invention also relates to a medical intelligent waist measurement method, comprising the following steps:

[0020] Step 1: First, disinfect the device and wipe the contact surfaces of the device with alcohol cotton, including the magnetic buckle, sensor belt, and OLED touch screen to ensure hygiene before measurement;

[0021] Step 2: The user should stand with their feet 25-30 cm apart, their upper limbs hanging naturally, and their body balanced. Wrap the device around the waist, ensuring that the magnetic buckle is tightly fixed and the device fits the skin around the waist without any looseness.

[0022] Step 3: Start the positioning module and use the bilateral infrared bone landmark scanning device to automatically identify and lock the midpoint of the line connecting the iliac crest and the costal arch in the mid-axillary line as the measurement point. After the infrared scan is completed, the device will beep to indicate that the positioning is complete. At this time, the robotic arm will automatically adjust to the midpoint position and perform horizontal calibration. If the robotic arm's built-in level detects that the measurement plane is tilted at an angle greater than 3°, the device will issue an alarm and the user will need to adjust their posture until the horizontal calibration is passed;

[0023] Step 4: After positioning and horizontal calibration are completed, the sensor belt will be slightly tightened, and the pressure will be constant at the standard value to ensure measurement accuracy. Within 3 seconds after the sensor belt is tightened, the device will complete the waist circumference measurement and display the waist circumference data in real time through the OLED touch screen. The user can view the waist circumference data through the touch screen and can choose to long press the screen to save the current measurement result, or feed the data back to the control center for storage via the Bluetooth module.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figure 1 and 2 As shown in FIG, a medical intelligent waist measurement system, the system consists of the following components:

[0033] It is mainly composed of positioning module, measurement module, display and transmission module, shell and wearable module and control terminal;

[0034] The positioning module includes:

[0035] Bilateral infrared bony landmark scanners: Installed on both sides of the device, they automatically scan and identify the midpoint of the line connecting the iliac crest and the costal arch at the midaxillary line. The scanners emit infrared light and receive reflected light, using an algorithm to analyze the intensity and position of the reflected light, accurately locking onto the measurement point with an error of less than ±0.2 cm.

[0036] Adjustable robotic arm: linked to the scanning device, once the measuring point is locked, the robotic arm automatically adjusts to the midpoint position to ensure that the sensor belt can accurately fit the point during measurement.

[0037] The measurement module includes:

[0038] Nanosilver flexible strain sensor: Specifically, it is a sensing strip with built-in nanosilver coating TPU (Ag+≥0.8μg / cm 2 ), the measuring range covers 60-150cm, which can accurately sense the changes in waist size. The sensor is slightly tightened during measurement, and the pressure is constant at the standard value (standard value <10N / cm 2 , such as 5N), to ensure comfort and accuracy of measurement.

[0039] A three-axis MEMS level with an accuracy of 0.1° ensures the measurement surface is level, preventing measurement errors caused by tilt. If the level detects a tilt angle greater than 3°, an alarm will sound, prompting the user to adjust their posture until the level is correct.

[0040] The display and transmission module includes:

[0041] OLED touch screen: Real-time display of waist circumference data, including measurement time, waist circumference value, horizontal deviation and confidence level. Users can manually correct or save measurement results through the touch screen.

[0042] Bluetooth module: supports the HL7 medical data standard, synchronizes measurement data to the control center, and realizes remote management and analysis of data.

[0043] The shell and wearable module include:

[0044] Magnetic detachable buckle: It is convenient for users to wrap the device around the waist and fix it. The magnetic design ensures that it is firmly worn and easy to remove.

[0045] Folding storage structure: After the measurement is completed, the device can be folded and stored for easy carrying and storage.

[0046] The control center is used to process and store data.

[0047] The specific measurement method is as follows:

[0048] Step 1: First, disinfect the device and wipe the contact surfaces of the device with alcohol cotton, including the magnetic buckle, sensor belt, and OLED touch screen to ensure hygiene before measurement;

[0049] Step 2: The user should stand with their feet 25-30 cm apart, their upper limbs hanging naturally, and their body balanced. Wrap the device around the waist, ensuring that the magnetic buckle is tightly fixed and the device fits the skin around the waist without any looseness.

[0050] Step 3: Start the positioning module and use the bilateral infrared bone landmark scanning device to automatically identify and lock the midpoint of the line connecting the iliac crest and the costal arch in the mid-axillary line as the measurement point. After the infrared scan is completed, the device will beep to indicate that the positioning is complete. At this time, the robotic arm will automatically adjust to the midpoint position and perform horizontal calibration. If the robotic arm's built-in level detects that the measurement plane is tilted at an angle greater than 3°, the device will issue an alarm and the user will need to adjust their posture until the horizontal calibration is passed;

[0051] Step 4: After positioning and horizontal calibration are completed, the sensor belt will be slightly tightened, and the pressure will be constant at the standard value to ensure measurement accuracy. Within 3 seconds after the sensor belt is tightened, the device will complete the waist circumference measurement and display the waist circumference data in real time through the OLED touch screen. The user can view the waist circumference data through the touch screen and can choose to long press the screen to save the current measurement result, or feed the data back to the control center for storage via the Bluetooth module.

[0052] In summary, the present invention achieves precise positioning of waist circumference measurement points and automatic calibration of measurement planes by adopting a bilateral infrared bone landmark scanning device and a three-axis MEMS level, which is beneficial to improving measurement accuracy and reliability, and at the same time helping to avoid errors caused by human factors in traditional measuring tools; and through the use of nano-silver flexible strain sensors and combined with intelligent sensing monitoring technology, it is beneficial to ensure comfort and safety during the measurement process; by using medical-grade safe materials in the device, it can be disinfected with high-temperature steam and alcohol after use, which is beneficial to facilitating daily disinfection work in medical institutions, avoiding cross infection, and improving safety of use.
