Limb Circumference Detection Device, Limb Compliance Measuring Device Composed of the Said Device, and Lymphedema Treatment Device

Abstract

A limb circumference detection device includes a wire-pulling module, a first measurement module, and a second measurement module. The wire-pulling module is disposed around the limb in a surrounding manner. The first measurement module is arranged on the wire-pulling module, and the second measurement module is connected to the wire-pulling module. The first measurement module moves along the long axis direction of the limb and simultaneously measures the length of the limb. When the second measurement module moves along the long axis direction of the limb, the first measurement module synchronously measures the length of the wire-pulling module surrounding the limb, thereby continuously detecting the correlation between the limb length and the circumference. Two sets or even more than two sets of the wire-pulling modules of the detection device can be used in parallel. When two sets of wire-pulling modules are used in parallel, they can be used to monitor the change in limb softness, that is, compliance. When multiple sets of wire-pulling modules are used in parallel, they can be used for the treatment of limb edema.

Description

Technical Field

[0001] The present invention relates to a limb circumference detection device, and more specifically, to a detection device that continuously measures the circumferences of various positions of a limb and can perform limb compliance measurement and limb edema treatment. Background Art

[0002] After breast cancer, gynecological or pelvic cancer patients receive surgical treatment, resection of lymph nodes and subsequent radiotherapy and chemotherapy can cause tissue fibrosis, blocking the lymphatic circulation path. This leads to the accumulation of lymph fluid in the tissues, causing swelling, which is called lymphedema, and is particularly likely to occur in the limbs.

[0003] Lymphedema is caused by an imbalance between the exudation and recovery of lymph fluid. Therefore, lymphedema usually does not occur immediately after surgery and radiotherapy and chemotherapy, but gradually occurs several months or even years later. Lymphedema can seriously affect the appearance, confidence and daily living functions of patients.

[0004] In view of the good early treatment effect after the occurrence of lymphedema, patients need a convenient device to monitor the limb circumference after surgery and radiotherapy and chemotherapy to track whether lymphedema occurs. In addition, recording the data of the patient's limb circumference enables medical staff to adjust the content of the rehabilitation plan according to the patient's condition to be more suitable for the patient.

[0005] Furthermore, it has been found from clinical experience that the compliance of a limb represents the internal pressure of the limb and may also be an indicator of the degree of swelling and treatment effect. Therefore, measurement is also necessary. Lymphedema can be relieved by manual lymphatic drainage, but manual lymphatic drainage needs to be performed by professional personnel, which is quite labor-intensive for professional personnel and can only be performed in medical institutions. Therefore, there is an urgent need to develop a device that can achieve the above treatment effects, which can not only save manpower but also facilitate patients to receive treatment at any time without having to go to a medical institution.

[0006] It can be seen from this that how to design a detection device that can quickly and accurately measure the limb circumference and limb compliance and also has the effect of edema treatment is still a problem to be overcome in the current industry. Summary of the Invention

[0080] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for the understanding and reading of those skilled in the art, and are not used to limit the limiting conditions for the implementation of the present invention.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present invention can be implemented. This is stated first for clarification.

[0081] Please refer to Figure 1 , Figure 1It is the first schematic diagram of the limb circumference detection device of the present invention. The present invention provides a limb circumference detection device, which includes a wire-pulling module 1, a first measurement module 2, and a second measurement module 3. The wire-pulling module 1 includes a surrounding component, and the surrounding component can be arranged to surround the limb 100. The first measurement module 2 and the second measurement module 3 are arranged on the wire-pulling module 1. The first measurement module 2 will move along the long axis direction of the limb 100 and measure the length of the limb 100. At the same time, the second measurement module 3 will synchronously measure the length of the wire-pulling module 1 surrounding the limb 100, that is, the circumference of the limb 100. The limb 100 can include an upper limb or a lower limb. In the embodiment of the present invention, the upper limb is taken as an example for illustration.

[0082] In Figure 1 In the shown embodiment, the wire-pulling module 1 may include a connecting wire 11. The surrounding component can be, for example, a bead chain 12 sleeved on the connecting wire 11. The bead chain 12 has the characteristics of being flexible but inextensible. The first measurement module 2 may include a roller 21 and a first rotation angle detection unit 22 connected to the roller 21. The first rotation angle detection unit 22 is used to measure the rotation angle of the roller 21. The second measurement module 3 may include a ratchet wheel 31 and a second rotation angle detection unit 32. The ratchet wheel 31 is arranged on the bead chain 12, and the second rotation angle detection unit 32 can be connected to the ratchet wheel 31. The function of the second rotation angle detection unit 32 is to measure the rotation angle of the ratchet wheel 31.

[0083] In this embodiment, the surrounding component of the wire-pulling module 1 can be the bead chain 12. The bead chain 12 can include an enclosing part 12a. The enclosing part 12a can be the part of the bead chain that surrounds the user's limb 100, such as the arm. The bead chain 12 has the characteristics of being flexible but inextensible. The roller 21 can be placed on the arm and start rolling from the starting point of the arm to be measured and recorded. More specifically, the roller 21 can move along the long axis direction of the arm, and the first rotation angle detection unit 22 synchronously measures the angle when the roller 21 rotates. The first rotation angle detection unit 22 can transmit the detected rotation angle value to an external arithmetic processing device 4, such as a mobile device or a computer. The arithmetic processing device 4 calculates the distance moved by the first measurement module 2 in real time from the obtained rotation angle. When the roller 21 rolls from the starting point of the arm to the end of the arm, the distance moved by the first measurement module 2 is the length of the arm.

[0084] Since different parts of the arm have different thicknesses, when the device moves along the long axis of the arm, the arm circumference changes. Under the fixed tension of the connecting line 11, the surrounding part 12a that slides along the outer periphery of the arm will expand or contract in coordination with the arm circumference. In one embodiment, the cable module 1 may further include a constant-tension spring group 13 and a fixed shaft 14. In this embodiment, the constant-tension spring group 13 refers to a tension spring with a default specific elastic coefficient. One end of the bead chain 12 can be connected to the fixed shaft 14, and the other end of the bead chain 12 is connected to one end of the connecting line 11. In another embodiment, the limb circumference detection device of the present invention may further install a bead chain pulley (not shown in the figure) at the fixed shaft 14. In this embodiment, one end of the bead chain 12 is connected to one end of the connecting line 11. After the bead chain 12 bypasses the pulley and turns, the other end of the bead chain 12 is connected back to the connecting line 11, which is used to reduce the moving distance of the end of the bead chain 12 and the connecting line 11. As for the other end of the connecting line 11, it is connected to the constant-tension spring group 13, and a spiral spring coil is arranged inside the constant-tension spring group 13. As the size of the arm circumference changes, the length of the surrounding part 12a increases or decreases accordingly. At this time, the spiral spring coil inside the constant-tension spring group 13 expands and contracts and rotates, pulling the connecting line 11 and the bead chain 12 to move, so as to maintain the fixed tension on the connecting line and the bead chain. Since the ratchet 31 engages with the bead chain 12, the movement of the bead chain 12 will drive the ratchet 31 to rotate at the same time. Then, the second rotation angle detection unit 32 synchronously measures and records the rotation angle of the ratchet 31 at different positions of the arm with different lengths. The second rotation angle detection unit 32 can also transmit the detected rotation angle value to an external mobile device or a computing and processing device 4 such as a computer. The computing and processing device 4 calculates the length of the surrounding part 12a in real time according to the rotation angle value of the ratchet 31, and this length is the arm circumference.

[0085] Please refer to Figure 2 , Figure 2 is a schematic diagram of the first link module of the present invention. The limb circumference detection device of the present invention may further include a first link module 5. The first link module 5 is designed based on the geometric principle that "the position of the midpoint of the hypotenuse of a right triangle is equidistant from the three vertices". The roller 21 can be installed on the horizontal cross plate 51 below the first link module 5. The horizontal cross plate can keep the roller 21 perpendicular to the surface of the limb 100 to be measured at any time, and a tension spring (not shown) can be provided inside the first link module 5. Under the action of the tension spring, the horizontal cross plate 51 is pressed down, and further presses the roller 21 to roll on the surface of the limb 100. At the same time, the first link module 5 can also pull the bead chain 12 through a groove (not shown) attached to the horizontal cross plate, so that the bead chain 12 moves synchronously with the roller 21 along the long axis direction of the limb 100.

[0086] Please refer to Figure 3 , Figure 3It is a schematic diagram of the double wire-pulling module of the present invention. The limb circumference detection device of the present invention may further include a double wire-pulling module 6, whose function is the same as that of Figure 2 the first link module 5 shown. In one embodiment, the roller 21 may be installed on the horizontal cross plate 61 whose two ends are pulled down by the pulling force of the double wire-pulling module 6. The horizontal cross plate 61 is lowered by the downward pulling force of the double wire-pulling module 6 pulling simultaneously with equal pulling force. Furthermore, in addition to allowing the roller 21 to be perpendicular to the surface of the limb 100 to be measured at any time, the horizontal cross plate 61 will also press the roller 21 to roll while adhering to the surface of the limb 100. At the same time, the double wire-pulling module 6 can also pull the bead chain 12 through the groove (not shown) attached under the horizontal cross plate 61, so that the bead chain 12 moves synchronously with the roller 21 along the long axis direction of the limb 100.

[0087] It should be particularly noted that the limb circumference detection device of the present invention Figure 2 the first link module 5 shown and Figure 3 the double wire-pulling module 6 shown, since their functions are the same, either one can be selected for use during implementation, or both can be used depending on the situation.

[0088] Please refer to Figure 4 , Figure 4 which is a schematic diagram of the second embodiment of the limb circumference detection device of the present invention. In this embodiment, the wire-pulling module 7 includes a surrounding component that can surround the limb 100, a constant-tension spring group 71, and a connection line 72 whose one end is connected to the constant-tension spring group 71. The surrounding component of the wire-pulling module 7, in this embodiment, is the measurement line 73. When in use, the surrounding component of the wire-pulling module 7, which is the measurement line 73 in this embodiment, may include an enclosing portion 73a, and the enclosing portion 73a may be the part of the measurement line that surrounds the limb 100 of the user, such as the arm. The measurement line 73 can be made of materials such as plastic, metal, or cotton yarn. The measurement line 73 has the characteristics of being flexible but inextensible.

[0089] On the other hand, the present invention can also use an optical motion sensor to replace the angle detection unit. The first measurement module 2 and the second measurement module 3 may respectively include a first optical motion sensing unit 23 and a second optical motion sensing unit 33. The first optical motion sensing unit 23 may be arranged at the contact position between the circumference detection device of the present invention and the upper-side skin of the limb 100. When the circumference detection device moves along the length direction of the limb 100, it drives the first measurement module 2 and the measurement line 73 to move synchronously. The first optical motion sensing unit 23 is used to sense the distance of movement along the length of the limb 100 and measure the length of the limb 100.

[0090] The second optical movement sensing unit 33 is disposed close to and above the measurement line 73 for measuring the circumference of the limb 100. There are two ways for the second optical movement sensing unit 33 to measure the circumference of the limb 100. One way is to measure the moving distance of the measurement line 73 and then obtain the circumference of the limb 100. Another feasible way to measure the circumference of the limb 100 is to dispose the second optical movement sensing unit 33 beside the side wall of the pulley (not shown in the drawing) used to guide the turning of the measurement line 73, measure the rotation radian of the pulley and convert it into the moving distance of the measurement line 73, and then obtain the circumference of the limb 100. Since the connecting line 72 has the same moving distance as the measurement line 73, the above-mentioned second optical movement sensing unit 33 can also be disposed above the connecting line 72 to measure the moving distance of the connecting line 72, or beside the side wall of the pulley used to guide the turning of the connecting line 72, measure the rotation radian of the pulley and convert it into the moving distance of the connecting line 72.

[0091] The length of the limb 100 obtained from the moving distance of the first optical movement sensing unit 23 along the length of the limb 100, and the circumference of the limb 100 obtained from the moving distance of the second optical movement sensing unit 33 measuring the measurement line 73 (or the connecting line 72) can both be transmitted to an external arithmetic processing device 4, such as a mobile device or a computer. The pulley angle measured by the second optical movement sensing unit 33 can also be converted by the arithmetic processing device 4 to convert the rotation radian of the pulley into the moving distance of the measurement line 73 (or the connecting line 72) to obtain the circumference of the limb 100.

[0092] Please refer to Figure 4 and Figure 5 , Figure 5 which is a schematic diagram of the second link module of the present invention. The circumference detection device of the present invention may further include at least one guiding clamp 80 and a second link module 81. In this embodiment, the circumference detection device of the present invention includes a plurality of guiding clamps 80, and the guiding clamps 80 can be evenly or unevenly distributed on the measurement line 73a and arranged around the limb 100. The second link module 81 is installed on both sides and the bottom side of the circumference detection device, and each guiding clamp 80 is installed on the second link module 81, so that the guiding clamp 80 adheres to the surface of the limb 100, and when the measurement line 73 moves in the circumference detection device, it can still adhere to the surface of the limb 100 at any time.

[0093] Specifically, the second link module 81 includes an outer frame 810, a first link 811, a second link 812, and a horizontal link 813. The outer frame 810 substantially surrounds the limb and has a strip-shaped card slot 8101, wherein the strip-shaped card slot 8101 can be substantially perpendicular to the long axis direction of the limb. The horizontal link 813 has two ends, one end of which is clamped in the strip-shaped card slot 8101 and is substantially perpendicular to the strip-shaped card slot 8101. The first link 811 has two ends, one end of which is slidably clamped in the strip-shaped card slot 8101. The second link 812 has two ends, one end of which is pivotally connected to the first link 811. The outer frame 810, the horizontal link 813, the first link 811, and the second link 812 are respectively connected to corresponding guide clamping blocks 80. The horizontal link 813 is disposed at a position on the bottom side of the limb circumference detection device close to the limb 100, and the first link 811 and the second link 812 are located above the horizontal link 813 and are used to guide the measurement line 73 to be close to the surface of the limb 100. The lifting mechanism design of the horizontal link 813 can adopt Figure 2 the same link mechanism as that shown in the link module 5, or can also adopt Figure 3 the same double wire-pulling mechanism as that shown in the double wire-pulling module 6.

[0094] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the limb compliance measurement device. As shown in the figure, the limb compliance measurement device includes two groups of wire-pulling modules 7 (including a constant-tension spring group 71, a connecting wire 72, and a measurement line 73), at least one group of first measurement modules 2 (including a first optical movement sensing unit 23), and two groups of second measurement modules 3 (including second optical movement sensing units 33). The two groups of wire-pulling modules 7 are respectively arranged around the limb 100 and are adjacent to each other. The two groups of wire-pulling modules 7 respectively apply different pulling force intensities to monitor the differential changes in the hardness of the limb 100. The first optical movement sensing unit 23 is arranged in the wire-pulling module 7 and is used to move along the long axis direction of the limb 100 and simultaneously measure the length of the limb 100. The two groups of second optical movement sensing units 33 are arranged in the two wire-pulling modules 7, and the second optical movement sensing unit 33 is used to synchronously measure the length of the corresponding surrounding parts 73a when the first optical movement sensing unit 23 moves along the long axis direction of the limb 100, so as to obtain the circumference of the limb 100.

[0095] The limb compliance measuring device of the present invention can be regarded as combining a limb circumference detecting device of the present invention with at least one of the cable pulling modules. Preferably, the cable pulling modules can be arranged in parallel. More preferably, the constant-tension spring groups of the cable pulling modules can selectively have the same or different tensile strengths. By arranging two cable pulling modules with different tensile forces in parallel and moving synchronously along the long axis direction of the limb 100, the circumference data of the same limb position under different tensile forces (i.e., the tightness of the measuring line) can be measured and obtained in real time. The difference between these two sets of data can be converted into the softness and hardness of the limb 100. In other words, the deviation of the limb circumference measurement value caused by the difference in tightness due to different tensile strengths reflects the softness and hardness (compliance) of the limb, thereby monitoring the difference change of limb compliance.

[0096] Please refer to Figure 7 , Figure 7 which is a schematic diagram of a lymphedema treatment device. The lymphedema treatment device includes a limb circumference detecting device of the present invention and a plurality of the cable pulling modules 7 (including a constant-tension spring group 71, a connecting line 72, and a measuring line 73). These cable pulling modules 7 are respectively arranged around the limb 100 and are adjacent to each other. Each cable pulling module 7 is used to apply a default tensile strength. More precisely, the constant-tension spring groups of the cable pulling modules can have various tensile strengths according to various treatment situations. In an embodiment of the present invention, the lymphedema treatment device may further include at least one first measuring module 2 (including a first optical movement sensing unit 23) and at least one second measuring module 3 (including a second optical movement sensing unit 33). At least one first optical movement sensing unit 23 is arranged on a corresponding cable pulling module 7 and is used to move along the long axis direction of the limb 100 and simultaneously measure the length of the limb 100. At least one second optical movement sensing unit 33 is arranged on the same cable pulling module 7. The second optical movement sensing unit 33 is used to synchronously measure the length of the corresponding surrounding portion 73a when the corresponding first optical movement sensing unit 23 moves along the long axis direction of the limb 100 to obtain the circumference of the limb 100.

[0097] In the embodiments of the limb compliance measuring device and the lymphedema treatment device of the present invention described above, the spacing between the cable pulling modules can be adjusted according to the component design and the condition of the patient's limb 100. Preferably, it can be set between 10 and 100 mm, but this is not a limitation.

[0098] As described above, the lymphedema treatment device of the present invention includes a limb circumference detection device of the present invention and a plurality of the wire-pulling modules, and different pulling force intensities are applied by the constant-tension spring groups 71 of the respective wire-pulling modules. Preferably, the lymphedema treatment device can be composed of a limb circumference detection device of the present invention and 2 to 9 of the wire-pulling modules. In this embodiment, the constant-tension spring groups 71 of the respective wire-pulling modules 7 respectively have preset different pulling forces. When the respective wire-pulling modules 7 are pulled along the arm in a fixed direction, the respective measuring wires 73 simultaneously apply pressure to the surface of the limb 100, thereby producing a treatment effect. The treatment principle is to apply appropriate pressure to the affected area to stimulate the smooth muscle contraction located on the lymphatic vessels, and cooperate with the appropriate drainage direction to redirect the interstitial lymph fluid to the superficial circulation, and then guide the excess lymph fluid back to the blood circulation through the anastomosis part of the superficial circulation to other normal-function lymph nodes.

The second end 8222 of the fourth link 822 can be connected to the guiding clamp block 80. The two third links 821 and the two fourth links 822 substantially surround the user's limb 100 and fix the guiding clamp block 80. The guiding clamp block 80 guides the surrounding portion 73a of the measuring wire 73 to make it close to the skin surface of the limb 100, and guides the measuring wire 73a to slide along the long axis direction of the limb 100. The lifting power of the third link module 82 and the guiding clamp block 80 is directly provided by the constant-tension spring group 71 at the other end of the measuring wire 73.
