[0035] In this embodiment, a portable limb measurement device is composed of the following parts: an outer frame 101, a plurality of telescopic rods 102 with adjustable lengths, a plurality of rollers 103 with a rotating function, a plurality of fixing sleeves 104, and a flexible measuring rope 105. These telescopic rods 102 are installed at the edges of the outer frame 101 so that the size of the entire device can be adjusted as needed; the movable end of each telescopic rod 102 is equipped with a sleeve 104 for fixing and guiding the position of the roller 103; the roller 103 is located on one side of the sleeve 104 and can rotate freely so that the measuring rope 105 can slide smoothly therebetween. When in use, the patient's limb can pass through the space in the middle of the measuring rope 105, so that the plurality of telescopic rods 102 can be squeezed to drive the measuring rope 105 to expand and contract with the circumference of the limb.

[0036] In addition, the device also includes a support frame 106 for providing stable support, and a sliding frame 107 that can slide on the support frame 106.

This design makes the overall structure both stable and flexible to meet the measurement needs of limbs of different sizes.

[0037] Both the support frame 106 and the sliding frame 107 are equipped with a placement rack 109. The main function of these placement racks 109 is to provide a support platform for the limb to be measured to ensure that the limb can remain stable during the measurement process. In order to further improve the measurement accuracy, a measuring unit 110 is also integrated at one end of the measuring rope 105. This measuring unit 110 can record the changes in the circumference of the limb according to the stretching state of the measuring rope 105, thereby achieving accurate data collection. When in use, the limb is passed through the measuring rope 105 and supported by two placement racks 109, and then the sliding block 108 is slid, and the changes in the circumference of the limb can be measured by the expansion and contraction changes of the measuring rope 105, and recorded by the measuring unit 110.

[0038] Through such a design, this portable limb measurement device is not only easy to carry but also easy to operate. It is very suitable for use in different environments, whether it is a medical institution or a sports venue, and can play its unique advantages.

[0039] The placement rack 109 has a flexible pad 111 , and the flexible pad 111 is arranged on the top of the placement rack 109 .

[0040] This flexible pad 111 is arranged on the top of the placement frame 109, which can effectively protect the limbs from being pressed by hard objects, while providing a comfortable placement experience to ensure that the limbs will not move due to discomfort during the measurement process.

[0041] The support frame 106 includes a support frame body 112, a stabilizing rod 113, a sliding rod 114 and a support rod 115. The stabilizing rod 113 is rotatably connected to the support frame body 112 and is located on one side of the support frame body 112. The support rod 115 is slidably connected to the support frame body 112 and is located at the bottom of the support frame body 112. The sliding rod 114 is slidably connected to the stabilizing rod 113 and is rotatably connected to the support rod 115.

[0042] In order to ensure that the support frame 106 remains stable during use, the support rod 115 can be slid to drive the sliding rod 114 and the stabilizing rod 113 to extend out of the support frame body 112 to provide triangular support. A clamping rod can be provided on the support rod 115 to limit the pulled-out support rod 115, so that the support is more stable.

[0043] The support frame 106 further includes a first anti-slip pad 116 , which is disposed at the bottom of the support frame body 112 .

[0044] In order to prevent the device from slipping during use, the support frame 106 further includes a first anti-slip pad 116 disposed at the bottom of the support frame body 112 to increase friction and ensure stability.

[0045] The support frame 106 further includes a rotating rod 117 , which is rotatably connected to the support frame body 112 and is located at the bottom of the support frame body 112 , and is used to increase the moving length of the sliding frame 107 and the sliding block 108 .

[0046] The support frame 106 further includes a rotating rod 117 for increasing the moving length of the sliding frame 107 and the sliding block 108 so that the device can adapt to a wider measurement range.

[0047] The rotating rod 117 includes a rotating rod body 118, a snap-fit ​​buckle 119, a first spring 120 and a control block 121. The rotating rod body 118 is rotatably connected to the supporting frame body 112. The snap-fit ​​buckle 119 is slidably set at one end of the rotating rod body 118 and matches with the slot on the supporting frame body 112. The first spring 120 is set between the snap-fit ​​buckle 119 and the rotating rod body 118. The control block 121 is fixedly connected to the snap-fit ​​buckle 119 and is located on one side of the snap-fit ​​buckle 119.

[0048] When the rotating rod body 118 is rotated, the snap buckle 119 can enter the slot on the supporting frame body 112 with the support of the first spring 120, so that it can remain stable and facilitate sliding. When it needs to be stored, the snap buckle 119 can be pulled out of the slot through the control block 121, making it more convenient to use.

[0049] The sliding frame 107 includes a sliding frame body 122 and a locking rod 123. The locking rod 123 is threadedly connected to the sliding frame body 122 and is located at one side of the sliding frame body 122. The position of the sliding frame 107 can be fixed by rotating the locking rod 123.

[0050] The sliding block 108 has a gripping portion 124, and the gripping portion 124 is located at one side of the sliding block 108, so that the user can manually adjust the position of the sliding block 108.

[0051] The measuring unit 110 includes a measuring spring 125, a tension sensor 126, a circumference change calculator 127, a display 128, a wireless transmission module 129 and a power supply 130. One end of the measuring spring 125 is connected to the measuring rope 105, and the other end of the measuring spring 125 is connected to the tension sensor 126. The circumference change calculator 127 is connected to the tension sensor 126. The display 128 is connected to the circumference change calculator 127. The wireless transmission module 129 is connected to the circumference change calculator 127. The power supply 130 is used to power other components.

[0052] The measuring unit 110 further includes a supporting wheel 131 , which is rotatably disposed on one side of the measuring rope 105 and is used to adjust the moving direction of the measuring rope 105 to be consistent with the deformation direction of the measuring spring 125 .

[0053] The measuring unit 110 is a highly integrated system, including a measuring spring 125, a tension sensor 126, a circumference change calculator 127, a display 128, a wireless transmission module 129, a power supply 130 and other components. One end of the measuring spring 125 is tightly connected to the measuring rope 105, and the other end is connected to the tension sensor 126. When the measuring rope 105 generates tension due to the change in the circumference of the limb, the tension will be transmitted to the measuring spring 125, thereby causing the measuring spring 125 to deform.

[0054] The tension sensor 126 is responsible for detecting the deformation degree of the measuring spring 125 and converting this physical quantity into an electrical signal output, which is then sent to the circumference change calculator 127 for processing. The circumference change calculator 127 integrates an advanced algorithm and can quickly and accurately calculate the change in limb circumference based on the data transmitted by the tension sensor 126. The calculation results will be displayed in real time on the display 128 for direct viewing by the operator or patient.

[0055] In addition to the local display, the measuring unit 110 is also equipped with a wireless transmission module 129, which can send the data processed by the circumference change calculator 127 to a designated receiving device, such as a doctor's computer or smart phone, via a wireless network, which greatly facilitates remote monitoring and data analysis. The realization of all these functions requires power support, so the measuring unit 110 has a built-in power supply 130 module for supplying power to other components to ensure the normal operation of the system.

[0056] In addition, in order to ensure that the tension of the measuring rope 105 can be accurately transmitted to the measuring spring 125, and to ensure that the measuring rope 105 does not deviate from the predetermined path when sliding, the measuring unit 110 also includes a support wheel 131. The support wheel 131 is designed to be rotatable and is placed on one side of the measuring rope 105. Its function is to adjust the direction of the measuring rope 105 when it moves, to ensure that the tension direction of the measuring rope 105 is consistent with the deformation direction of the measuring spring 125, thereby improving the accuracy and reliability of the measurement.

[0057] Second embodiment

[0058] See also Figure 8 The present invention also provides a method for using a portable limb measurement device, comprising:

[0059] S201 Slide the sliding frame 107 to a preset position and fix it;

[0060] The operator needs to adjust the position of the sliding frame 107 on the support frame 106 according to the body part and size to be measured until the sliding frame 107 reaches a suitable preset position. Once the suitable position is found, the locking mechanism (such as the locking rod 123) on the sliding frame 107 is used to fix it at this position to ensure that the sliding frame 107 does not move during the measurement process.

[0061] S202: The user's limb is passed through the hole formed by the measuring rope 105, and supported by the support frame 106 and the placement frame 109 on the sliding frame 107;

[0062] The user is guided to pass the limb to be measured (such as an arm or a leg) through the hole naturally formed by the measuring rope 105, so that the limb is located inside the measuring rope 105. At this time, the limb should be placed on the placement frame 109 equipped on the support frame 106 and the sliding frame 107, and the flexible pad 111 on the placement frame 109 is used to give the limb sufficient support to ensure that the limb remains still and comfortable during the measurement process.

[0063] S203: Move the sliding block 108 to the starting section of the edema portion, then start the measurement of the measuring unit 110, and move the sliding block 108 to the ending section of the edema portion.

[0064] Move the sliding block 108 along the sliding frame 107 to the starting point of the edema part, that is, the place where the edema begins. At this time, start the measuring unit 110 and start recording the circumference change of the limb. As the sliding block 108 moves slowly, the measuring rope 105 will slide along the surface of the limb until it reaches the end of the edema part. In this process, the measuring unit 110 will continue to monitor the tension change of the measuring rope 105 and record the relevant data. Finally, according to the data display provided by the measuring unit 110 or the data sent to the external device through the wireless transmission module 129, the specific circumference change information about the edema part can be obtained.
