Description

Technical Field

[0001] The invention relates to the field of intelligent detection, and specifically to a multifunctional examination bed and a body index detection method thereof. Background Art

[0002] At present, the postoperative treatment and rehabilitation plan of many critically ill patients are closely related to BMI. However, since critically ill patients cannot get out of bed after surgery, their height, weight and changes in body shape after surgery are difficult to measure, which causes two problems. First, due to the uncertainty of height and weight and the uncertainty of change value, it is impossible to accurately monitor the patient's BMI value, making it difficult to formulate some rehabilitation plans after surgery. Secondly, after some back, waist and leg surgeries, the patient's bed posture is irregular and most of the time they cannot lie flat, making it very difficult to measure their height. The invention patent with publication number CN113855000A discloses a bed sheet and a measurement method for measuring the height of bedridden patients. Due to the setting of the scale lines on the bed sheet body, the patient's height can be measured according to the scale values ​​of the scale lines when lying in bed. At the same time, the setting of the zero-degree line facilitates medical staff to quickly find the reference position, thereby improving the efficiency of measuring height. The invention patent with publication number CN117959107A discloses a device for measuring the weight of bedridden patients, which can calculate the weight of a patient lying on a lying board according to the measured value of a tension sensor device. After the measurement is completed, the reclining board is lowered to the bed, and the patient can leave the reclining board by moving a little and lying on his side; then the device can be removed. The invention can measure the weight of multiple patients at the same time. The utility model patent with publication number CN221731296U discloses a bed-crossing board that can measure weight and height. Thanks to the cooperation of the bed-crossing board body, the sliding groove, the first limiting member, the infrared ranging receiver and the infrared ranging transmitter, when the bed-crossing board body is used to assist the patient to cross the bed, the first limiting member and the second limiting member can be used to press against the patient's head and feet respectively, and then the infrared ranging transmitter can be used to measure the height of the patient. The distance measuring receiver and the infrared distance measuring transmitter are used to measure the distance between the first limit piece and the second limit piece, so as to quickly measure the patient's height data. At the same time, in conjunction with the bed board, the electronic weighing plate and the weight display screen, after the bed board is settled, the patient's weight data can be quickly detected by the electronic weighing plate. It can be seen that the measuring beds in the prior art all use the traditional height and weight measurement method to measure the patient, and do not take into account the inaccuracy in weight measurement, the irregularity in long-term recording, and the inaccurate patient posture in height measurement. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a multifunctional examination bed and a body index detection method thereof.

[0004] A multifunctional examination bed and a method for detecting body indicators thereof, comprising the following steps: Step 1: Classify the patients and divide bedridden patients into Grade I, Grade II, and Grade III according to their surgical conditions.

[0005] Furthermore, step two: the patient's classification and initial physical condition are transmitted to the information storage system through the information transmission system, and the information storage system is provided with a height information storage system, a weight information storage system, and a BMI information storage system; wherein the information in the weight information storage system and the BMI information storage system is updated in real time according to the number of days in bed.

[0006] Further, step three: place the patients of grades I-III on the multifunctional examination bed after the operation. The multifunctional examination bed has a first state and a second state. The multifunctional examination bed is initially set to the first state.

[0007] Furthermore, in step four, the multifunctional examination bed is connected to the control device, and a signal for detecting the height and weight of the patient on the bed is sent to the multifunctional examination bed through the control device.

[0008] Furthermore, step five: before detecting the height, first determine the patient's grade according to the patient's information in the information storage system, and make a specific height detection strategy according to the patient's grade.

[0009] Furthermore, in step six, the weight data of the patient is first detected in the first state of the examination bed, and the weight of the patient is detected at a certain time every day by the control device.

[0010] Furthermore, step seven: after the patient's weight is detected in the first state of the examination bed, the first state of the examination bed is monitored. If the monitoring is normal, the weight information of the day is transmitted to the weight information storage system in the information storage system. If it is abnormal, the examination bed is changed to the second state.

[0011] Furthermore, step eight: after detecting the weight and height information of the day, the BMI information is calculated and transmitted to the BMI information storage system.

[0012] Furthermore, in step nine, when the examination bed is in state one, the patient's weight is tested every day, and the test results are monitored after each test. If the monitored data is incorrect, the examination bed is changed to the second state.

[0013] Furthermore, in step ten, the corresponding BMI value is calculated based on the measured patient height data and the daily monitored patient weight data and updated in the information storage system, and the patient's rehabilitation plan is customized based on the daily updated value.

[0014] Furthermore, in step one, surgeries that are not large in scale and in which the patient is bedridden but can change posture in bed after the surgery are classified as Level I; surgeries that are medium in scale and in which the patient is bedridden and cannot change posture in bed by himself but can change posture with the help of a doctor are classified as Level II; surgeries that are large in scale and in which the patient cannot change posture in bed after the surgery are classified as Level III.

[0015] Furthermore, in step three, the multifunctional examination bed is an inflatable bed, whose first state is an inflated support state, and whose second state is a deflated compressed state; an inflatable layer is provided inside the multifunctional examination bed, and air is inflated into the inflatable layer through an inflating device.

[0016] Furthermore, in step three, a support layer is provided below the inflation layer of the multifunctional examination bed, a sensor layer is provided above the inflation layer, and a plurality of weight detection sensor units are arranged at various positions in the sensor layer.

[0017] Furthermore, in step three, each weight detection sensing unit includes a sensor unit, a converter unit, and a data transmission unit; the sensor unit includes a sensor circuit, the sensor circuit includes a Uv positive pole and a Uv negative pole and a connecting circuit connected between the Uv positive pole and the Uv negative pole, and four strain gauge resistors R1, R2, R3, and R4 are arranged on the connecting circuit. When the four strain gauge resistors detect a weight change, the resistance changes. The sensor circuit is connected to the converter unit, and the converter unit is an AD converter. The AD converter amplifies the voltage data and transmits it to the data transmission unit. The data transmission unit is a data transmission unit.

[0018] Furthermore, in step three, the weight detection sensor units are set to N, and the sensor circuits of the N weight detection sensor units are connected through the converter unit and the data transmitter unit. The N data transmitters are connected through connecting lines, and the N data transmitters can exchange and monitor their respective data. After the data is exchanged and monitored, if the data is accurate, it will be transmitted to the display screen for display.

[0019] Furthermore, in step three, the first state of the multifunctional examination bed is an inflated state, and the second state is a deflated state. Four compression springs are arranged at the four corners of the bottom of the multifunctional examination bed, and a tension spring is connected in the middle of the multifunctional examination bed. The four compression springs are all provided with connecting rods connected to the tension parts of the tension springs.

[0020] Furthermore, in step five, the multifunctional examination bed is divided into M dividing lines from the head to the foot of the bed, the dividing lines are parallel to the head of the bed, and the first area, the second area, the third area...the Mth area are formed between adjacent dividing lines; the upper and lower dividing lines in each area are adjacent to each other by Xcm.

[0021] Furthermore, in step five, if the patient belongs to level I according to the information storage system, the patient lies flat on the bed by himself, and infrared technology is used to transmit infrared rays to the top of the patient's head and the soles of the feet to obtain the patient's height; if the patient belongs to level II according to the information storage system, the patient lies flat on the bed with the help of a doctor, and infrared technology is used to transmit infrared rays to the top of the patient's head and the soles of the feet to obtain the patient's height.

[0022] Furthermore, in step five, if the patient belongs to level III according to the information storage system, the patient's bed posture is first observed. If the posture is curled up and not lying flat, the position of the patient's head is first determined by infrared technology, and a straight line segment is drawn from the top of the patient's head downwards. The specific position of the patient's feet is determined by infrared technology, and the angle between the patient's foot position and the straight line segment is α.

[0023] Furthermore, in step 5, the length from the top of the head to the feet of the Class III patient in the curled-up state is measured by infrared as L 0， Then estimate the patient's height, and record the area of ​​the examination bed where the patient's head is located and the area of ​​the examination bed where the patient's feet are located. The area where the head is located is recorded as area A, and the area where the feet are located is recorded as area B. Both areas A and B are between areas 1-M. The length between the upper dividing line of area A and the lower dividing line of area B is L2, and the average value between L1 and L2 is taken as the patient's height.

[0024] Furthermore, in step seven, after the patient's weight is detected in the first state, normal and abnormal information of the weight is determined in the data transmitter of each weight detection sensor unit, and since the information between each data transmitter can be transmitted and shared, if the data of a certain weight detection sensor unit is abnormal, it is determined that the weight detection data in the first state is inaccurate, the gas in the inflation layer is released to change the bed to the second state, and the patient's weight is measured using Hooke's theorem through the deformation of the tension spring and compression spring at the bottom of the bed.

[0025] Compared with the prior art, the present invention has the following beneficial effects: The present invention ensures the stability and accuracy of weight detection by setting the multifunctional examination bed to two states to detect weight respectively. When the electronic detection in the first state fails, the device switches to the second state for mechanical detection to prevent problems with the electronic detection. The body weight and BMI are monitored for a long time to correspond to appropriate postoperative rehabilitation methods. Different height detection strategies are used to detect the height of patients in different postoperative conditions, solving the problem that the height of patients who cannot move after surgery cannot be detected.
