DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with specific 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.

[0047] Example 1

[0048] A clothing pressure monitoring module includes a flexible double-layer airbag 110, a solenoid valve 201, an air pump 202, and an air pressure sensor 203;

[0049] like Figure 1 As shown, the flexible double-layer airbag 110, the air pump 202 and the air pressure sensor 203 are connected together through a pipeline to form a closed pressure system. Furthermore, a solenoid valve 201 is provided on the pipeline at the output end of the air pump 202, and the end of the pipeline is connected to a three-way 211. The other two ports of the three-way 211 are respectively connected to the air pressure sensor 203 and the flexible double-layer airbag 110 through pipelines. The air pump 202 is used to inflate the entire pressure system. The solenoid valve 201 has two states, open and closed. The open state is used for the pressure system to take in air in the initial stage and to deflate the pressure system after the measurement is completed. The closed state is used to maintain the pressure stability of the pressure system during the measurement process. The air pressure sensor 203 is used to sense the inflation pressure of the air pump 202 in real time and monitor the overall pressure changes of the pressure system.

[0050] Example 2

[0051] like Figure 2 As shown, when the flexible double-layer airbag 110 is subjected to external pressure, the external pressure causes the internal pressure of the flexible double-layer airbag 110 to change. Since it is a closed pressure system, the pressure inside the entire pressure system changes.

[0052] Based on the above principles, this embodiment provides a working method of the clothing pressure monitoring module described in Embodiment 1, including the following steps:

[0053] Open the solenoid valve 201 and use the air pump to inflate the entire closed system until the value sensed by the air pressure sensor 203 reaches the set initial pressure (100Pa). Close the solenoid valve 201 and place the flexible double-layer airbag 110 between the clothing and the skin. Since the gravity of the clothing squeezes the flexible double-layer airbag 110, the pressure of the entire pressure system changes accordingly. At this time, the pressure monitored by the air pressure sensor 203 is the relative pressure of the clothing, and the actual pressure of the clothing is the relative pressure minus the initial pressure of the pressure system.

[0054] Example 3

[0055] like Figure 4 As shown, this embodiment provides a method for manufacturing a flexible double-layer airbag 110, wherein a flexible film layer 105 is cut with a fixed mold, and in this embodiment, it is cut into a circle with a diameter of 42 mm; a 3D printed trachea connector 106 is placed 5 mm away from the edge of a flexible film layer 105, and the trachea connector 106 is fixed to the flexible film layer 105 with glue, and then another flexible film layer 105 is covered on the flexible film layer 105 with the trachea connector 106, and the outer edges of the two flexible film layers 105 are integrally packaged using a pasting process to form a flexible double-layer airbag 110 with an internal diameter of 40 mm.

[0056] Furthermore, after the trachea connector 106 is connected to the trachea 101 (the pipeline connected to the flexible double-layer airbag 110 in Example 1), the trachea 101 is connected to one port of the tee 211 through the trachea air inlet joint 103 .

[0057] Example 4

[0058] This embodiment uses the clothing pressure monitoring module provided in Embodiment 1 to evaluate the comfort of the medical elastic sleeve and measure the overall pressure distribution of the medical elastic sleeve on the arm. Since the pressure exerted by the medical elastic sleeve on the human arm is not completely equal at all positions, during the pressure measurement process, the flexible double-layer airbags 110 of the three pressure monitoring modules are placed at different positions between the human arm and the medical elastic sleeve to obtain the pressure distribution at the arm position.

[0059] The evaluation process is as follows: three flexible double-layer airbags 110 are attached to different positions of the arm and the solenoid valve 201 is opened. Three air pumps 202 are inflated respectively until the flexible double-layer airbags 110 are inflated and reach the specified initial air pressure (100Pa). After the entire pressure system remains stable, the solenoid valve 201 is closed;

[0060] A medical elastic sleeve is put on the arm, and three flexible double-layer airbags 110 are located between the medical elastic sleeve and the arm. Due to the gravity of the medical elastic sleeve, the pressure inside the flexible double-layer airbag 110 will change, and the pressure of the entire pressure system will change accordingly. At this time, the pressure monitored by the air pressure sensor 203 is the relative pressure of the medical elastic sleeve, and the actual pressure of the medical elastic sleeve is the relative pressure minus the initial pressure of the pressure system (100Pa).

[0062] like Figure 5-Figure 7 As shown, a multifunctional clothing comfort evaluation device includes one or more clothing pressure monitoring modules, a control box 200, a sensor module 100, a data receiving and transmitting unit and a host computer 300 as described in Example 1, wherein the sensor module 100 is used to collect pressure, temperature, humidity and skin sweat signals of the human body in the clothing, the sensor module 100 is connected to the data receiving and transmitting unit, the data receiving and transmitting unit is arranged in the control box 200, the data receiving and transmitting unit is connected to the host computer 300, and is used to transmit the collected signals to the host computer 300, and the host computer 300 is used to process the received signals and perform visual display. The air pump 202 is arranged in the control box 200, and an air outlet 213 is arranged on the control box 200, and the air pump 202 is connected to the flexible double-layer airbag 110 through the air outlet 213 and the air pipe 101.

[0063] like Figure 3 As shown, the sensor module 100 includes one or more sensor groups. When in use, multiple sensor groups are arranged at different positions. Each sensor group includes a temperature sensor 140, a humidity sensor 120 and a sweat sensor 130 that are packaged together through a hot pressing process. The flexible double-layer airbag 110 is packaged together with each sensor through a hot pressing process. The output ends of the air pressure sensor 203, the temperature sensor 140, the humidity sensor 120 and the sweat sensor 130 are respectively connected to the male connector 104 through a wire 102. A female connector 214 is arranged on the control chassis 200. The male connector 104 is plugged into the female connector 214. The female connector 214 is connected to the signal receiving end of the data receiving and transmitting unit through the wire 102.

[0064] The data receiving and transmitting unit includes an air pressure module 208, a temperature module 204, a humidity module 205, a sweat module 206 and a data transmission module 210 arranged in a control chassis 200. The input end of the air pressure module 208 is connected to the air pressure sensor 203, and its output end is connected to the input end of the data transmission module 210 through a daisy chain. The input end of the temperature module 204 is connected to the temperature sensor 140, and its output end is connected to the input end of the data transmission module 210 through a daisy chain. The input end of the humidity module 205 is connected to the humidity sensor 120, and its output end is connected to the input end of the data transmission module 210 through a daisy chain. The input end of the sweat module 206 is connected to the sweat sensor 130, and its output end is connected to the input end of the data transmission module 210 through a daisy chain. The output end of the data transmission module 210 is connected to the host computer 300 through a data transmission line 301.

[0065] Furthermore, a power module 209 and a relay module 207 are provided in the control box 200, and the temperature module 204, the humidity module 205, the sweat module 206, the relay module 207, the air pressure module 208 and the data transmission module 210 (in this embodiment, an isolated RS-232 / 485 conversion module) are connected to the power module 209, and an LED lamp 212 is installed on the control box 200, and the LED lamp 212 and the air pump 202 are connected to the relay module 207, and the relay module 207 is connected to the data transmission module 210, which is used to receive the control signal sent by the host computer 300. If the LED lamp 212 is on, the program in the host computer 300 runs successfully, and all the above modules are powered on, otherwise the program runs malfunction. In this embodiment, a plurality of LED lamps 212, an air outlet 213, and a female connector 214 are provided in the control box 200 to adapt to a plurality of clothing pressure monitoring modules.

[0066] The host computer 300 is provided with a control unit, which is a device control program developed based on LABVIEW software, and the data and control signal are transmitted through the program. The LABVIEW software includes an adaptive pressure measurement algorithm, which can adjust the power of the air pump 202 according to the pressure inside the garment to be tested (i.e., the flexible double-layer airbag 110), and adjust the flow rate during the inflation process of the air pump 202, so that the pressure inside the flexible double-layer airbag 110 will not fluctuate greatly during the entire measurement process, avoiding the impact of excessive flow rate on the internal gas, and ensuring the accuracy of pressure measurement.

[0067] Example 6

[0068] like Figure 8 As shown, this embodiment provides an evaluation method for the multifunctional clothing comfort evaluation device described in Example 5:

[0069] Open the LABVIEW software and perform initialization operations. After initialization, collect data on pressure, temperature, humidity, and sweat.

[0070] In the process of collecting pressure, first, the relay module 207 receives the software instruction, the relay module 207 is closed, the air pump 202 starts working, and the air pressure module 208 monitors the state of the flexible double-layer airbag 110 in real time. The gas pumped by the air pump 202 continuously enters the flexible double-layer airbag 110 to increase the internal pressure of the pressure system. When the pressure inside the pressure system reaches the set pressure, the relay module 207 receives the feedback information from the air pressure module 208, the solenoid valve 201 is closed, the air pump 202 stops working, the flexible double-layer airbag 110 is inflated, and then the flexible double-layer airbag 110 is placed between the human body and the clothing. Due to the gravity of the clothing, the pressure inside the flexible double-layer airbag 110 will change, so that the pressure of the entire pressure system changes. The air pressure sensor 203 collects the pressure of the pressure system in real time and uploads the collected pressure to the host computer 300. The software of the host computer 300 will continue to record the pressure value until the measurement is completed.

[0071] In the temperature collection process, after the software completes the initialization operation, the temperature module 204 receives the instruction, and the temperature module 204 starts to work, collects the electrical signal generated by the temperature sensor 140 in real time, and displays the temperature curve on the software interface until the pressure measurement process is completed.

[0072] During the humidity collection process, after the software completes the initialization operation, the humidity module 205 receives the instruction, and the humidity module 205 starts to work, collects the electrical signal generated by the humidity sensor 120 in real time, and displays the temperature curve on the software interface until the pressure measurement process is completed.

[0073] During the sweat collection process, after the software completes the initialization operation, the sweat module 206 receives the instruction, and the sweat module 206 starts to work, collects the electrical signal generated by the sweat sensor 130 in real time, and displays the sweat analysis curve on the software interface until the pressure measurement process is completed.

[0074] The host computer 300 displays the curves of pressure, temperature, humidity and sweat in real time. After the measurement, all the collected data in the system are exported and a spreadsheet in Excel format is generated.

[0075] After the measurement is completed, the host computer 300 analyzes the data generated by the measurement and makes a comprehensive evaluation of the comfort of human clothing. Among them, the pressure value, temperature value, humidity value and sweat composition, researchers can adjust the proportion of each according to the selected model. At the same time, the software can build in a reference model for the comprehensive evaluation of human comfort under different conditions, which can provide a reference for later research and analysis.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
